1 Introduction

Over the natural course of severe acute pancreatitis (SAP)intestinal permeability has been found to increase within thefirst 72 hours which led to massive endotoxin also knownas the lipopolysaccharide (LPS) aggregates to be uptakeninto blood circulationwhich initiates the occurrence of endo-toxemia [1] Previous study has described that endotoxemiawould initiate the consistent proinflammatory changes ingenic and proteinic expression profile of the immune cellswhich would trigger inflammatory cascade reaction andthen cause the serious dysfunction of capillary endothelium[2] Because pulmonary capillary networks are extremelyenriched in the early stage endotoxemia would initiate thesevere damage to pulmonary capillary endothelial barrier andthen cause acute lung injury (ALI) [3] The analyses of SAP-induced extrapancreatic organs injury indicated that ALI

not only occurs at the earliest stage but also initiates themost serious injury among these extrapancreatic organs [3]The SAP endotoxemia-induced ALI would directly lead toa significant decrease in ventilationperfusion ratio whicheventually result in respiratory failure [4] And the incidenceof ALI in SAP patients is 20 and the mortality rate is ashigh as 15 to 25 [4] Therefore alleviating SAP endo-toxemia-induced ALI could decrease the mortality rate inSAP The physiopathologic mechanisms of the damage topulmonary capillary endothelial barrier mainly include thedisassembly of tight junction (TJ) and adherens junction (AJ)and reorganization of cytoskeleton which would enhancepulmonary albumin leak and then result in the extra-vascularleak of the increased albumin leak-induced edema fluid intopulmonary interstitial and alveolar compartments and even-tually initiate respiratory failure [5 6] Hence pulmonaryalbumin leakage is the key pathophysiological mechanism

of ALI Additionally albumin with high molecular weightwould leak across capillary endothelial barrier mainly depen-dent on the paracellular leakage [7] Therefore the enhance-ment to systemic and pulmonary albumin leak depravationof airways indicators respiratory dysfunction and also theadverse change in lung tissue pathology could be consideredas the important features of pulmonary capillary endothelialbarrier injury [8ndash10] Moreover the reversal of the enhancedpulmonary albumin leak should be considered as the thera-peutic goal for ALI caused by endotoxemia in SAP

CQCQD decoction a famous Chinese medicinal for-mula has been used to treat SAP for decades in WestChina Hospital Sichuan University [11] According to theregulations on drug development and approval of SFDAbefore the Chinese medicinal formula is widely used inclinical practice there are four main principles required tobe met by the Chinese medicinal formula (1) action targetarea (2) highly efficient concentration (3) efficacy in animalmodel (4) multicentral random clinical trial The growingstudies evidences of CQCQD indicated that the first threeprinciples mentioned above have been met which will beshown as follows (i) action target area (1) pancreatic tissues(2) gastrointestinal tract (3) lung (4) immune system (5)pancreatic acinar cells (6) alveolar macrophages and (7)peritoneal macrophages [12ndash25] which suggested that thelungs are the important action target area for CQCQD(ii) Highly efficient concentration in clinical practice is asfollows CQCQD consists of Bupleuri Radix (Chai Hu) 15 gScutellariae Radix (Huang Qin) 15 g Magnoliae OfficinalisCortex (Hou Pu) 15 g Aurantii Fructus Immaturus (Zhi Shi)15 g Artemisiae Scopariae Herba (Yin Chen) 15 g GardeniaeFructus (Zhi Zi) 20 g Rhei Radix et Rhizoma (Da Huang)20 g and Natrii Sulfas (Mang Xiao) 20 g [12] according tothe standardized preparation procedure of CQCQD formulathese eight herbs will be decocted to form this decoction [13]since this decoction has been used to treat SAP for decadesand the effective pharmacotherapy to the patients has beencertified with ALI caused by endotoxemia in SAP [14] if thisdecoction is prepared strictly according to CQCQD formulaand the standardized preparation procedure the final con-centration of the prepared decoction can represent the highlyefficient concentrations of CQCQD in clinical application[15] (iii) Efficacy in SAP animal model is as follows (1)effectively ameliorating pancreatic histopathological changesand systemic inflammatory response [16ndash23] (2) effectivelyimproving gastrointestinal motility dysfunction [23] (3)effectively ameliorating alveolar inflammatory response [24](4) effectively alleviating ALI [25] which suggested that thetherapy of CQCQD could effectively alleviate the ALI causedby endotoxemia in SAP animal model Meanwhile accordingto the 4th principle multicentral random clinical trials arebeing conducted in a number of hospitals in China includingWest China Hospital of Sichuan University Chengdu No 1Hospital and Sichuan Hospital of TCM Although the multi-central randomclinical trials have not been completed a largenumber of clinical studies have provided the key evidencesthat (1) the therapy of CQCQD significantly decreased serumlevels of interleukin-6 (IL-6) and IL-1120573 receptor antagonist(IL-1ra) in SAP patients and also the hospitalization time of

SAP patients [12] (2) the therapy of CQCQD could decreasethe serum levels of matrix metalloproteinase-9 (MMP-9)C-reactive protein (CRP) and amyloid A (SAA) to relievethe durations of acute respiratory distress syndrome (ARDS)in patients with SAP [13 14] and the early application ofCQCQD is more effective than late application to shortenthe duration of ARDS [15] which suggested that the therapyof CQCQD could probably effectively alleviate ALI in thepatients with SAP Furthermore there are growing evidencesfor the monomers isolated from the herbs of CQCQDdecoction that (1) saikosaponin A baicalin and chlorogenicacid could inhibit some proinflammatory signal pathwayto ameliorate inflammatory cascade reaction [26ndash28] (2)saikosaponin C and baicalein could inhibit LPS-inducedapoptosis in human umbilical vein endothelial cells [2930] (3) wogonin could inhibit LPS-induced vascular hyper-permeability via inhibiting cytoskeleton reorganization [31]Consequently we speculated that the treatment of CQCQDdecoction in the patients with SAP endotoxemia-inducedALI could potentially ameliorate pulmonary albumin leak viadepressing the inflammatory cascade reaction and alleviatingthe damage to cell-cell junction However the potentialmolecular mechanisms have not been systematically studied

In this study microarray and Western blot and so forthanalyses were employed to reveal the key molecular mech-anisms for CQCQD decoction in alleviating the pulmonaryalbumin leakage caused by endotoxemia in SAP rats

these 5 pathways including inflammatory response (Toll-likereceptor signaling pathway) paracellular leakage (adherensjunction tight junction and regulation of actin cytoskele-ton) and apoptosis (apoptosis) (119875 lt 005 entitles ≧ 3Table 2) And then the DEGs (CS DEGs cluster) enrichedin these KEGG pathways were inputted into NetworkAn-alyst database to construct a PPI network (nodes = 623edges = 868 and seed proteins = 72) The top three nodeswith the highest degree and betweenness (degree gt40 andbetweenness gt1000) were Fos (protooncogene c-Fos) Pik3r1(phosphatidylinositol 3-kinase regulatory subunit alpha) andSrc (protooncogene tyrosine-protein kinase Src) respectively(Figure 2(a))Therefore the 3 proteins including c-Fos c-Srcand p85120572 encoded by these 3 genes were considered as theprioritized hub proteins and also predicted as the key targetproteins for CQCQD to attenuate pulmonary albumin leak-age Furthermore these 3 genes displayed the expression pat-terns of CS reversing SN (119875 lt 005 | log 2(Ratio)| ≧ 0585)which were shown in the heatmap (Figure 2(b))

38 Effects of the Pretreatment of CQCQD on the LPS-Induced Expression Changes in These 3 Predicted Proteins inHUVECs Imitating the Actions of the Selective InhibitionsAgents of These Predicted Target Proteins Since the selectiveinhibitions agents of these predicted target proteins show thesignificant alleviating effects on LPS-mediated paracellularleakage and proinflammatory cytokines release in HUVECsthe analyses of the expression of these predicted targetproteins were required to reveal the molecular mechanisms

HUVECs were treated as described previously and thenWestern blot analyses were performed This study providedthe important evidences that (1) LPS observably induced thehigh expressions of p-Src p-p85120572 and c-Fos compared withthat in Normal group (119875 lt 005 Figure 4) but did not inducethe significant changes in expression of nonphosphorylatedSrc and p85120572 compared with that in Normal group(119875 gt 005 Figures 4(a) and 4(b)) (2) the pretreatment withthe inhibitors of c-Src (PP1) remarkably inhibited

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

of ALI Additionally albumin with high molecular weightwould leak across capillary endothelial barrier mainly depen-dent on the paracellular leakage [7] Therefore the enhance-ment to systemic and pulmonary albumin leak depravationof airways indicators respiratory dysfunction and also theadverse change in lung tissue pathology could be consideredas the important features of pulmonary capillary endothelialbarrier injury [8ndash10] Moreover the reversal of the enhancedpulmonary albumin leak should be considered as the thera-peutic goal for ALI caused by endotoxemia in SAP

CQCQD decoction a famous Chinese medicinal for-mula has been used to treat SAP for decades in WestChina Hospital Sichuan University [11] According to theregulations on drug development and approval of SFDAbefore the Chinese medicinal formula is widely used inclinical practice there are four main principles required tobe met by the Chinese medicinal formula (1) action targetarea (2) highly efficient concentration (3) efficacy in animalmodel (4) multicentral random clinical trial The growingstudies evidences of CQCQD indicated that the first threeprinciples mentioned above have been met which will beshown as follows (i) action target area (1) pancreatic tissues(2) gastrointestinal tract (3) lung (4) immune system (5)pancreatic acinar cells (6) alveolar macrophages and (7)peritoneal macrophages [12ndash25] which suggested that thelungs are the important action target area for CQCQD(ii) Highly efficient concentration in clinical practice is asfollows CQCQD consists of Bupleuri Radix (Chai Hu) 15 gScutellariae Radix (Huang Qin) 15 g Magnoliae OfficinalisCortex (Hou Pu) 15 g Aurantii Fructus Immaturus (Zhi Shi)15 g Artemisiae Scopariae Herba (Yin Chen) 15 g GardeniaeFructus (Zhi Zi) 20 g Rhei Radix et Rhizoma (Da Huang)20 g and Natrii Sulfas (Mang Xiao) 20 g [12] according tothe standardized preparation procedure of CQCQD formulathese eight herbs will be decocted to form this decoction [13]since this decoction has been used to treat SAP for decadesand the effective pharmacotherapy to the patients has beencertified with ALI caused by endotoxemia in SAP [14] if thisdecoction is prepared strictly according to CQCQD formulaand the standardized preparation procedure the final con-centration of the prepared decoction can represent the highlyefficient concentrations of CQCQD in clinical application[15] (iii) Efficacy in SAP animal model is as follows (1)effectively ameliorating pancreatic histopathological changesand systemic inflammatory response [16ndash23] (2) effectivelyimproving gastrointestinal motility dysfunction [23] (3)effectively ameliorating alveolar inflammatory response [24](4) effectively alleviating ALI [25] which suggested that thetherapy of CQCQD could effectively alleviate the ALI causedby endotoxemia in SAP animal model Meanwhile accordingto the 4th principle multicentral random clinical trials arebeing conducted in a number of hospitals in China includingWest China Hospital of Sichuan University Chengdu No 1Hospital and Sichuan Hospital of TCM Although the multi-central randomclinical trials have not been completed a largenumber of clinical studies have provided the key evidencesthat (1) the therapy of CQCQD significantly decreased serumlevels of interleukin-6 (IL-6) and IL-1120573 receptor antagonist(IL-1ra) in SAP patients and also the hospitalization time of

SAP patients [12] (2) the therapy of CQCQD could decreasethe serum levels of matrix metalloproteinase-9 (MMP-9)C-reactive protein (CRP) and amyloid A (SAA) to relievethe durations of acute respiratory distress syndrome (ARDS)in patients with SAP [13 14] and the early application ofCQCQD is more effective than late application to shortenthe duration of ARDS [15] which suggested that the therapyof CQCQD could probably effectively alleviate ALI in thepatients with SAP Furthermore there are growing evidencesfor the monomers isolated from the herbs of CQCQDdecoction that (1) saikosaponin A baicalin and chlorogenicacid could inhibit some proinflammatory signal pathwayto ameliorate inflammatory cascade reaction [26ndash28] (2)saikosaponin C and baicalein could inhibit LPS-inducedapoptosis in human umbilical vein endothelial cells [2930] (3) wogonin could inhibit LPS-induced vascular hyper-permeability via inhibiting cytoskeleton reorganization [31]Consequently we speculated that the treatment of CQCQDdecoction in the patients with SAP endotoxemia-inducedALI could potentially ameliorate pulmonary albumin leak viadepressing the inflammatory cascade reaction and alleviatingthe damage to cell-cell junction However the potentialmolecular mechanisms have not been systematically studied

In this study microarray and Western blot and so forthanalyses were employed to reveal the key molecular mech-anisms for CQCQD decoction in alleviating the pulmonaryalbumin leakage caused by endotoxemia in SAP rats

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Figure 5 Correlations among the expressions of p-Src p-p85120572 and c-Fos and LPS-induced paracellular leakage and the change in TEER aswell as LPS-induced proinflammatory cytokines release in HUVECs (benchmark logarithmic scale = 10 120588 gt 098 versus dextran flux orthe levels of TNF-120572 or IL-6 or IL-1120573 120588 lt minus098 versus TEER 120588 gt 098 versus dextran flux and 120588 lt minus098 versus TEER)

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

Except Natrii Sulfas the other seven dried componentsof Chinese drug decoction pieces were immersed in coldwater for 60 minutes and then individually milled ExceptRhei Radix et Rhizoma the other six milled components ofthe Chinese drug decoction pieces were admixed in the pre-scribed proportion (ww) as shown inTable 1 and thenwereextracted in 10-fold (wv) of purified water by the decoctingmethod for two times (40 minuteseach time) according togood manufacturing practices (GMP) at the College of thePharmacy of Sichuan University At the last ten minutes inthe second decocting extraction the milled component ofRhei Radix et Rhizoma drug decoction pieces was added tothe extract liquids according to the prescribed proportion (ww) as shown in Table 1 for further decocting extractionAfterwards the mixing extracts of the seven Chinese drugdecoction pieces and the pure product of Natrii Sulfas wereadmixed according to the prescribed proportion ( ww) asshown in Table 1 The extracts were filtered concentratedspray-dried and lyophilized to obtain a powder (2844 yieldww based on the raw materials of Chinese drug decoctionpieces)The aliquots weremanufactured into clinical productthrough the addition of water-soluble sodium carboxymethylstarch (excipient) according to the proportion of 1 1 (ww)Before administration to animals the lyophilized powder ofCQCQD was prepared to a concentration of 24 gmL ofcrude herbsaqua pro injectione Rat medicated serums wereprepared according to published protocols [32] Briefly 10rats were randomly divided into blank group and CQCQDgroup Rats in CQCQD group were treated with CQCQD(01mL10 g bw times 1 time2 hrs 6 times) by intragastric

administration while rats in blank group only received thesame amount of normal saline After the last administrationblood from the rats was collected and centrifuged to prepareCQCQD-containing serum and control serum Finally theserums were stored at minus20∘Cprior to useThe previous reportindicated that CQCQD-containing serum at the concentra-tion of 10 was more effective than that at 5 in improvingthe viability of pancreatic acinar cells in SAP rats [33] It canbe concluded that highly efficient concentration of CQCQD-containing serum would probably be considered as 10Therefore the CQCQD-containing serum or control serumwas diluted to the concentration of 10 by using DMEMmedium respectively

23 Experimental Design For in vivo trial rats were ran-domly divided into sham-operation (SO) SAP and CQCQDgroup (119899 = 20group) In this paper ldquoSAP grouprdquo was usedto represent ldquoSAP endotoxemia-induced ALI model grouprdquoSAP endotoxemia-induced ALI model was induced byretrograde main pancreatic duct injection of 5 sodiumtaurocholate (1mLkg bw) combined with cecal ligation-perforation (CLP) At 1 hr after operation rats in CQCQDgroup were treated with CQCQD (01mL10 g bw times 1time2 hrs 6 times) by intragastric administration while ratsin the other two groups only received the same amount ofsaline At 1 hr before the end of experiment 5 rats fromeach group received intravenous injection of 2 Evans blue(EB) (2mLkg) At 12 hours after operation blood sampleswere collectedThenusing Infusion Pump (FreseniusVial SAFrance) the blood in the pulmonary circulation was clearedaway After that the tissues on the edge of 05 cm in thelungs of rats in each group were collected For in vitro trialaccording to our research targets HUVECs were divided intothe following six groups (1) Normal group (pretreated withnormal rat serums for 1 hr and then added DMEM mediumwith 10 FBS and coincubated for 12 hrs) (2) LPS group(pretreated with normal rat serums for 1 hr and then added1 120583M LPS and coincubated for 12 hrs) (3) CQCQD group(pretreated with CQCQDmedicated serums for 1 hr and thenadded 1 120583MLPS and coincubated for 12 hrs) (4)ndash(6) selectiveinhibition agents groups (pretreated with normal rat serums+ inhibitors of c-Src (PP1 10 120583M) or PI3K (LY294002 30 120583M)or transfected with siRNAs of c-Fos and then added 1 120583MLPSand coincubated for 12 hrs)

24 Gene Expression Profiling and Data Analysis The SOgroup SAP group and CQCQD group were represented bythe letters N S and C respectively The gene expressionprofiles of lung tissue in each sample were determined usingRat OneArray Plus Microarray (Phalanx Biotech Taiwan)The data of Rat OneArray Plus were analyzed using RosettaResolver System (Rosetta Biosoftware) Annotation ROA2release 10 (databases NCBI RefSeq release 65 and Ensemblerelease 76 cDNA sequences Rnor 50 annotations) and R303 software (httpwwwr-projectorg) DEGswere identi-fied as119875 lt 005 and | log 2(Ratio)| ≧ 0585 by unpaired t-testThe functional enrichment analyses of KEGG pathways asso-ciated with the lists of genes were generated by WebGestalt(httpwwwwebgestaltorg) (119875 lt 005 and entitles ge3)

required demonstrating the important involvements of these3 predicted target proteins in LPS-mediated changes inTEERparacellular leakage and proinflammatory cytokines releasein HUVECs HUVECs were pretreated with the inhibitorsof c-Src (PP1) or PI3K (LY294002) or transfected withsiRNAs of c-Fos which provided the important evidencesthat the pretreatment with PP1 or LY294002 as well asthe transfection with siRNAs of c-Fos remarkably reversedLPS-induced increases in proinflammatory cytokines releaseand paracellular leakage and also the decrease in TEER(119875 lt 005 Table 6) Strikingly the pretreatment ofCQCQD imitated the actions of the selective inhibitionsagents of these predicted proteins to significantly reverseLPS-mediated increase in paracellular leakage and proin-flammatory cytokines release as well as the decrease in TEER(119875 lt 005 Table 6)

38 Effects of the Pretreatment of CQCQD on the LPS-Induced Expression Changes in These 3 Predicted Proteins inHUVECs Imitating the Actions of the Selective InhibitionsAgents of These Predicted Target Proteins Since the selectiveinhibitions agents of these predicted target proteins show thesignificant alleviating effects on LPS-mediated paracellularleakage and proinflammatory cytokines release in HUVECsthe analyses of the expression of these predicted targetproteins were required to reveal the molecular mechanisms

HUVECs were treated as described previously and thenWestern blot analyses were performed This study providedthe important evidences that (1) LPS observably induced thehigh expressions of p-Src p-p85120572 and c-Fos compared withthat in Normal group (119875 lt 005 Figure 4) but did not inducethe significant changes in expression of nonphosphorylatedSrc and p85120572 compared with that in Normal group(119875 gt 005 Figures 4(a) and 4(b)) (2) the pretreatment withthe inhibitors of c-Src (PP1) remarkably inhibited

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Figure 5 Correlations among the expressions of p-Src p-p85120572 and c-Fos and LPS-induced paracellular leakage and the change in TEER aswell as LPS-induced proinflammatory cytokines release in HUVECs (benchmark logarithmic scale = 10 120588 gt 098 versus dextran flux orthe levels of TNF-120572 or IL-6 or IL-1120573 120588 lt minus098 versus TEER 120588 gt 098 versus dextran flux and 120588 lt minus098 versus TEER)

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

32 Predictions of the Target Proteins for CQCQD to AttenuatePulmonary Albumin Leakage Based on the Analyses of RatsPulmonaryTissueMicroarray andAlso theConstruction of PPINetwork The KEGG pathway enrichment analyses closelyrelated to paracellular leakage-dependent albumin leakageprovided the important evidences that some of the DEGs inCS and SN DEGs clusters were significantly enriched in

these 5 pathways including inflammatory response (Toll-likereceptor signaling pathway) paracellular leakage (adherensjunction tight junction and regulation of actin cytoskele-ton) and apoptosis (apoptosis) (119875 lt 005 entitles ≧ 3Table 2) And then the DEGs (CS DEGs cluster) enrichedin these KEGG pathways were inputted into NetworkAn-alyst database to construct a PPI network (nodes = 623edges = 868 and seed proteins = 72) The top three nodeswith the highest degree and betweenness (degree gt40 andbetweenness gt1000) were Fos (protooncogene c-Fos) Pik3r1(phosphatidylinositol 3-kinase regulatory subunit alpha) andSrc (protooncogene tyrosine-protein kinase Src) respectively(Figure 2(a))Therefore the 3 proteins including c-Fos c-Srcand p85120572 encoded by these 3 genes were considered as theprioritized hub proteins and also predicted as the key targetproteins for CQCQD to attenuate pulmonary albumin leak-age Furthermore these 3 genes displayed the expression pat-terns of CS reversing SN (119875 lt 005 | log 2(Ratio)| ≧ 0585)which were shown in the heatmap (Figure 2(b))

37 Effect of the Pretreatment of CQCQD on LPS-MediatedChanges in TEER Paracellular Leakage and Proinflamma-tory Cytokines Release in HUVECs Imitating the Actions ofthe Selective Inhibitions Agents of These Predicted ProteinsAs shown in Table 6 LPS-stimulated HUVECs show theremarkable increase in proinflammatory cytokines releaseand dextran flux (paracellular leakage) compared to that inNormal group (119875 lt 005) meanwhile TEER in LPS groupwas significantly lower than that in Normal group (119875 lt005) According to the analyses results of the PPI net-work constructed by the analyses of ratsrsquo pulmonary tissuemicroarray c-Fos c-Src and p85120572 were predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage Additional information p85120572 is encoded byPik3r1 [38] c-Fos is encoded by Fos [39] and c-Src is encodedby Src [40] In order to verify these predictions that firstly

required demonstrating the important involvements of these3 predicted target proteins in LPS-mediated changes inTEERparacellular leakage and proinflammatory cytokines releasein HUVECs HUVECs were pretreated with the inhibitorsof c-Src (PP1) or PI3K (LY294002) or transfected withsiRNAs of c-Fos which provided the important evidencesthat the pretreatment with PP1 or LY294002 as well asthe transfection with siRNAs of c-Fos remarkably reversedLPS-induced increases in proinflammatory cytokines releaseand paracellular leakage and also the decrease in TEER(119875 lt 005 Table 6) Strikingly the pretreatment ofCQCQD imitated the actions of the selective inhibitionsagents of these predicted proteins to significantly reverseLPS-mediated increase in paracellular leakage and proin-flammatory cytokines release as well as the decrease in TEER(119875 lt 005 Table 6)

38 Effects of the Pretreatment of CQCQD on the LPS-Induced Expression Changes in These 3 Predicted Proteins inHUVECs Imitating the Actions of the Selective InhibitionsAgents of These Predicted Target Proteins Since the selectiveinhibitions agents of these predicted target proteins show thesignificant alleviating effects on LPS-mediated paracellularleakage and proinflammatory cytokines release in HUVECsthe analyses of the expression of these predicted targetproteins were required to reveal the molecular mechanisms

HUVECs were treated as described previously and thenWestern blot analyses were performed This study providedthe important evidences that (1) LPS observably induced thehigh expressions of p-Src p-p85120572 and c-Fos compared withthat in Normal group (119875 lt 005 Figure 4) but did not inducethe significant changes in expression of nonphosphorylatedSrc and p85120572 compared with that in Normal group(119875 gt 005 Figures 4(a) and 4(b)) (2) the pretreatment withthe inhibitors of c-Src (PP1) remarkably inhibited

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Figure 5 Correlations among the expressions of p-Src p-p85120572 and c-Fos and LPS-induced paracellular leakage and the change in TEER aswell as LPS-induced proinflammatory cytokines release in HUVECs (benchmark logarithmic scale = 10 120588 gt 098 versus dextran flux orthe levels of TNF-120572 or IL-6 or IL-1120573 120588 lt minus098 versus TEER 120588 gt 098 versus dextran flux and 120588 lt minus098 versus TEER)

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

HUVECs were treated as described previously and thenWestern blot analyses were performed This study providedthe important evidences that (1) LPS observably induced thehigh expressions of p-Src p-p85120572 and c-Fos compared withthat in Normal group (119875 lt 005 Figure 4) but did not inducethe significant changes in expression of nonphosphorylatedSrc and p85120572 compared with that in Normal group(119875 gt 005 Figures 4(a) and 4(b)) (2) the pretreatment withthe inhibitors of c-Src (PP1) remarkably inhibited

LPS-induced high expression of p-Src (119875 lt 005 Figure 4(a))but did not induce the significant change in expression ofnonphosphorylated Src compared with that in Normal orLPS group (119875 gt 005 Figure 4(a)) (3) the pretreatmentwith the inhibitors of PI3K (LY294002) markedly suppressedLPS-induced high expression of p-p85120572 (119875 lt 005Figure 4(b)) but did not trigger the significant change inexpression of nonphosphorylated p85120572 compared withthat in Normal or LPS group (119875 gt 005 Figure 4(b)) (4)the transfection with siRNAs of c-Fos evidently inhibitedLPS-induced overexpression of c-Fos (119875 lt 005 Figure 4(c))(5) strikingly the pretreatment of CQCQD on HUVECssuccessfully imitated the actions of the selective inhibitionsagents in the same way to inhibit LPS-mediated highexpressions of p-Src p-p85120572 and c-Fos (119875 lt 005 Figure 4)and likewise did not induce the significant changes inexpressions of nonphosphorylated Src and p85120572 comparedwith that in Normal or LPS group (119875 gt 005 Figures 4(a)and 4(b)) Therefore the inhibition effects of LPS-mediatedhigh expressions of p-Src p-p85120572 and c-Fos were thekey molecular mechanisms for CQCQD or the selectiveinhibitions agents acting on these 3 predicted target proteins

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Figure 5 Correlations among the expressions of p-Src p-p85120572 and c-Fos and LPS-induced paracellular leakage and the change in TEER aswell as LPS-induced proinflammatory cytokines release in HUVECs (benchmark logarithmic scale = 10 120588 gt 098 versus dextran flux orthe levels of TNF-120572 or IL-6 or IL-1120573 120588 lt minus098 versus TEER 120588 gt 098 versus dextran flux and 120588 lt minus098 versus TEER)

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

32 Predictions of the Target Proteins for CQCQD to AttenuatePulmonary Albumin Leakage Based on the Analyses of RatsPulmonaryTissueMicroarray andAlso theConstruction of PPINetwork The KEGG pathway enrichment analyses closelyrelated to paracellular leakage-dependent albumin leakageprovided the important evidences that some of the DEGs inCS and SN DEGs clusters were significantly enriched in

these 5 pathways including inflammatory response (Toll-likereceptor signaling pathway) paracellular leakage (adherensjunction tight junction and regulation of actin cytoskele-ton) and apoptosis (apoptosis) (119875 lt 005 entitles ≧ 3Table 2) And then the DEGs (CS DEGs cluster) enrichedin these KEGG pathways were inputted into NetworkAn-alyst database to construct a PPI network (nodes = 623edges = 868 and seed proteins = 72) The top three nodeswith the highest degree and betweenness (degree gt40 andbetweenness gt1000) were Fos (protooncogene c-Fos) Pik3r1(phosphatidylinositol 3-kinase regulatory subunit alpha) andSrc (protooncogene tyrosine-protein kinase Src) respectively(Figure 2(a))Therefore the 3 proteins including c-Fos c-Srcand p85120572 encoded by these 3 genes were considered as theprioritized hub proteins and also predicted as the key targetproteins for CQCQD to attenuate pulmonary albumin leak-age Furthermore these 3 genes displayed the expression pat-terns of CS reversing SN (119875 lt 005 | log 2(Ratio)| ≧ 0585)which were shown in the heatmap (Figure 2(b))

38 Effects of the Pretreatment of CQCQD on the LPS-Induced Expression Changes in These 3 Predicted Proteins inHUVECs Imitating the Actions of the Selective InhibitionsAgents of These Predicted Target Proteins Since the selectiveinhibitions agents of these predicted target proteins show thesignificant alleviating effects on LPS-mediated paracellularleakage and proinflammatory cytokines release in HUVECsthe analyses of the expression of these predicted targetproteins were required to reveal the molecular mechanisms

HUVECs were treated as described previously and thenWestern blot analyses were performed This study providedthe important evidences that (1) LPS observably induced thehigh expressions of p-Src p-p85120572 and c-Fos compared withthat in Normal group (119875 lt 005 Figure 4) but did not inducethe significant changes in expression of nonphosphorylatedSrc and p85120572 compared with that in Normal group(119875 gt 005 Figures 4(a) and 4(b)) (2) the pretreatment withthe inhibitors of c-Src (PP1) remarkably inhibited

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Figure 5 Correlations among the expressions of p-Src p-p85120572 and c-Fos and LPS-induced paracellular leakage and the change in TEER aswell as LPS-induced proinflammatory cytokines release in HUVECs (benchmark logarithmic scale = 10 120588 gt 098 versus dextran flux orthe levels of TNF-120572 or IL-6 or IL-1120573 120588 lt minus098 versus TEER 120588 gt 098 versus dextran flux and 120588 lt minus098 versus TEER)

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

37 Effect of the Pretreatment of CQCQD on LPS-MediatedChanges in TEER Paracellular Leakage and Proinflamma-tory Cytokines Release in HUVECs Imitating the Actions ofthe Selective Inhibitions Agents of These Predicted ProteinsAs shown in Table 6 LPS-stimulated HUVECs show theremarkable increase in proinflammatory cytokines releaseand dextran flux (paracellular leakage) compared to that inNormal group (119875 lt 005) meanwhile TEER in LPS groupwas significantly lower than that in Normal group (119875 lt005) According to the analyses results of the PPI net-work constructed by the analyses of ratsrsquo pulmonary tissuemicroarray c-Fos c-Src and p85120572 were predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage Additional information p85120572 is encoded byPik3r1 [38] c-Fos is encoded by Fos [39] and c-Src is encodedby Src [40] In order to verify these predictions that firstly

required demonstrating the important involvements of these3 predicted target proteins in LPS-mediated changes inTEERparacellular leakage and proinflammatory cytokines releasein HUVECs HUVECs were pretreated with the inhibitorsof c-Src (PP1) or PI3K (LY294002) or transfected withsiRNAs of c-Fos which provided the important evidencesthat the pretreatment with PP1 or LY294002 as well asthe transfection with siRNAs of c-Fos remarkably reversedLPS-induced increases in proinflammatory cytokines releaseand paracellular leakage and also the decrease in TEER(119875 lt 005 Table 6) Strikingly the pretreatment ofCQCQD imitated the actions of the selective inhibitionsagents of these predicted proteins to significantly reverseLPS-mediated increase in paracellular leakage and proin-flammatory cytokines release as well as the decrease in TEER(119875 lt 005 Table 6)

38 Effects of the Pretreatment of CQCQD on the LPS-Induced Expression Changes in These 3 Predicted Proteins inHUVECs Imitating the Actions of the Selective InhibitionsAgents of These Predicted Target Proteins Since the selectiveinhibitions agents of these predicted target proteins show thesignificant alleviating effects on LPS-mediated paracellularleakage and proinflammatory cytokines release in HUVECsthe analyses of the expression of these predicted targetproteins were required to reveal the molecular mechanisms

HUVECs were treated as described previously and thenWestern blot analyses were performed This study providedthe important evidences that (1) LPS observably induced thehigh expressions of p-Src p-p85120572 and c-Fos compared withthat in Normal group (119875 lt 005 Figure 4) but did not inducethe significant changes in expression of nonphosphorylatedSrc and p85120572 compared with that in Normal group(119875 gt 005 Figures 4(a) and 4(b)) (2) the pretreatment withthe inhibitors of c-Src (PP1) remarkably inhibited

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Figure 5 Correlations among the expressions of p-Src p-p85120572 and c-Fos and LPS-induced paracellular leakage and the change in TEER aswell as LPS-induced proinflammatory cytokines release in HUVECs (benchmark logarithmic scale = 10 120588 gt 098 versus dextran flux orthe levels of TNF-120572 or IL-6 or IL-1120573 120588 lt minus098 versus TEER 120588 gt 098 versus dextran flux and 120588 lt minus098 versus TEER)

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

37 Effect of the Pretreatment of CQCQD on LPS-MediatedChanges in TEER Paracellular Leakage and Proinflamma-tory Cytokines Release in HUVECs Imitating the Actions ofthe Selective Inhibitions Agents of These Predicted ProteinsAs shown in Table 6 LPS-stimulated HUVECs show theremarkable increase in proinflammatory cytokines releaseand dextran flux (paracellular leakage) compared to that inNormal group (119875 lt 005) meanwhile TEER in LPS groupwas significantly lower than that in Normal group (119875 lt005) According to the analyses results of the PPI net-work constructed by the analyses of ratsrsquo pulmonary tissuemicroarray c-Fos c-Src and p85120572 were predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage Additional information p85120572 is encoded byPik3r1 [38] c-Fos is encoded by Fos [39] and c-Src is encodedby Src [40] In order to verify these predictions that firstly

38 Effects of the Pretreatment of CQCQD on the LPS-Induced Expression Changes in These 3 Predicted Proteins inHUVECs Imitating the Actions of the Selective InhibitionsAgents of These Predicted Target Proteins Since the selectiveinhibitions agents of these predicted target proteins show thesignificant alleviating effects on LPS-mediated paracellularleakage and proinflammatory cytokines release in HUVECsthe analyses of the expression of these predicted targetproteins were required to reveal the molecular mechanisms

HUVECs were treated as described previously and thenWestern blot analyses were performed This study providedthe important evidences that (1) LPS observably induced thehigh expressions of p-Src p-p85120572 and c-Fos compared withthat in Normal group (119875 lt 005 Figure 4) but did not inducethe significant changes in expression of nonphosphorylatedSrc and p85120572 compared with that in Normal group(119875 gt 005 Figures 4(a) and 4(b)) (2) the pretreatment withthe inhibitors of c-Src (PP1) remarkably inhibited

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Figure 5 Correlations among the expressions of p-Src p-p85120572 and c-Fos and LPS-induced paracellular leakage and the change in TEER aswell as LPS-induced proinflammatory cytokines release in HUVECs (benchmark logarithmic scale = 10 120588 gt 098 versus dextran flux orthe levels of TNF-120572 or IL-6 or IL-1120573 120588 lt minus098 versus TEER 120588 gt 098 versus dextran flux and 120588 lt minus098 versus TEER)

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

38 Effects of the Pretreatment of CQCQD on the LPS-Induced Expression Changes in These 3 Predicted Proteins inHUVECs Imitating the Actions of the Selective InhibitionsAgents of These Predicted Target Proteins Since the selectiveinhibitions agents of these predicted target proteins show thesignificant alleviating effects on LPS-mediated paracellularleakage and proinflammatory cytokines release in HUVECsthe analyses of the expression of these predicted targetproteins were required to reveal the molecular mechanisms

HUVECs were treated as described previously and thenWestern blot analyses were performed This study providedthe important evidences that (1) LPS observably induced thehigh expressions of p-Src p-p85120572 and c-Fos compared withthat in Normal group (119875 lt 005 Figure 4) but did not inducethe significant changes in expression of nonphosphorylatedSrc and p85120572 compared with that in Normal group(119875 gt 005 Figures 4(a) and 4(b)) (2) the pretreatment withthe inhibitors of c-Src (PP1) remarkably inhibited

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Figure 5 Correlations among the expressions of p-Src p-p85120572 and c-Fos and LPS-induced paracellular leakage and the change in TEER aswell as LPS-induced proinflammatory cytokines release in HUVECs (benchmark logarithmic scale = 10 120588 gt 098 versus dextran flux orthe levels of TNF-120572 or IL-6 or IL-1120573 120588 lt minus098 versus TEER 120588 gt 098 versus dextran flux and 120588 lt minus098 versus TEER)

p-Src p-p85120572 and c-Fos could suppress LPS-induced para-cellular leakage and proinflammatory cytokines release Andthen our in vitro studies successfully confirmed these pre-dictions (1) the pretreatment of CQCQD on LPS-stimulatedHUVECs which imitated the actions of the selective inhibi-tions agents to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Figure 4) (2) ultimately significantly

alleviated LPS-mediated increase in paracellular leakage andproinflammatory cytokines release as well as the decrease inTEER (Table 6)The above evidences suggested that CQCQDcould probably attenuate the paracellular leakage-dependentalbumin leak via reversing endotoxemia-triggered expres-sions changes in these predicted target proteinsThe potentialmolecular mechanisms were further analyzed as follows

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

39 Correlations among the Expressions of p-Src p-p85120572 andc-Fos and LPS-Induced Paracellular Leakage and the Changein TEER as well as LPS-Induced Proinflammatory CytokinesRelease in HUVECs According to the benchmark logarith-mic scale of 10 the line charts had been formed and then thecorrelational analyses were performed among the expressionsof p-Src p-p85120572 and c-Fos and LPS-induced paracellularleakage and the change in TEER as well as LPS-inducedproinflammatory cytokines release in HUVECs The 120588 valueof correlation coefficient is calculated based on the originaldata of these parameters but not the logarithmic data Thisstudy provided the first evidences that (1) the expressions ofp-Src p-p85120572 and c-Fos were positively correlated with LPS-induced paracellular leakage and proinflammatory cytokinesrelease (120588 gt 098) and negatively correlated with LPS-induced changes in TEER (120588 lt minus098) which demon-strated the very highly linear regression correlation (Figures5(a) 5(b) and 5(c)) (2) there were also the remarkablypositive correlations between LPS-induced proinflammatorycytokines release and LPS-induced paracellular leakage (120588 gt098) and also the notably negative correlations between LPS-induced proinflammatory cytokines release and LPS-inducedchanges in TEER (120588 lt minus098) which show the highly linearregression correlation (Figure 5(d))

4 Discussion

The methods of intraperitoneal (IP) or intratracheal (IT)injection of LPS-inducing lung injury are simple but theycannot simulate the natural course of SAP endotoxemia-induced ALI [41] Therefore we used the methods of retro-grade main pancreatic duct injection of 5 sodium tauro-cholate combined with cecal ligation-perforation to establishSAP endotoxemia-induced ALI model After cecal ligationthe feces were accumulated in cecum and then the punctureby using 18 needle was performed on the ligated cecum to

form 3 holes After that the mixed bacteria in the intestinalcontents constantly enter into the abdominal cavity to inducethe infection of the abdominal cavity which would resultin endotoxemia or sepsis and eventually initiate pulmonaryalbumin leakage to trigger ALI Hence the models inducedby retrograde main pancreatic duct injection of sodiumtaurocholate combined with cecal ligation-perforation couldrealistically demonstrate the pathophysiological process ofSAP endotoxemia-induced ALI that is more close to the trueprocess in clinic [41] Strikingly retrograde main pancreaticduct injection of 5 sodium taurocholate combined withcecal ligation-perforation successfully induced SAP com-plicated with endotoxemia (Table 3) the enhancement tosystemic and pulmonary albumin leak (Table 4) deprava-tion of airways indicators (Table 5) respiratory dysfunction(Table 5) and also the adverse change in pancreatic andpulmonary tissue pathology (Figure 3) which suggested thatthe models of ALI caused by endotoxemia in SAP rats weresuccessfully constructed Fortunately the therapy of CQCQDshowed the protective effects on the rats of SAP endotoxemia-induced ALI via significantly ameliorating the changes in theabove characteristics indexes (Tables 3 4 and 5 and Figure 3)

The pathophysiological mechanisms of alleviating para-cellular leakage-dependent albumin leak mainly include (1)inhibiting the excessive reassembly of F-actin and the reorga-nization of cytoskeleton (2) suppressing the disassembly ofTJs AJs and F-actin at cell-cell contact sites (3) reassemblingTJs AJs and F-actin at damaged cell-cell contact sites(4) maintaining AJs TJs and the homeostasis of actin(5) suppressing apoptosis and (6) inhibiting inflammatoryresponse [42] In our study the analyses of rats pulmonarytissues microarray and also the construction of PPI networkprovided the important evidences that (1) some DEGs in CSand SN DEGs clusters were significantly enriched in the 5KEGG pathways closely related to the above pathophysiolog-ical mechanisms (Table 2) (2) there were the 3 prioritizedhub proteins (c-Fos c-Src and p85120572) to be predicted as thekey target proteins for CQCQD in alleviating pulmonaryalbumin leakage and these 3 genes displayed the expressionpatterns of CS reversing SN (Figure 2) In order to verifythese predictions that firstly required demonstrating theimportant involvements of these 3 predicted target proteinsin LPS-mediated changes in TEER paracellular leakage andproinflammatory cytokines release in HUVECs and thenfurther investigate the molecular mechanisms involved ourstudies in vitro provided the several important evidencesthat (1) the selective inhibition agents of these 3 predictedtarget proteins remarkably reversed LPS-induced increases inproinflammatory cytokines release and paracellular leakageas well as the decrease in TEER (Table 6) (2) the inhibitioneffects of LPS-mediated high expressions of p-Src p-p85120572and c-Fos were the key molecular mechanisms for theselective inhibitions agents acting on these predicted targetproteins (Figure 4) (3) the expressions of p-Src p-p85120572 andc-Fos were highly and positively correlated with LPS-inducedparacellular leakage and proinflammatory cytokines releaseand highly and negatively correlated with LPS-inducedchanges in TEER (Figures 5(a) 5(b) and 5(c)) which sug-gested that inhibitions of LPS-mediated high expressions of

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos

Alleviating Paracellular Leakage via Inhibiting the Expres-sions of Upstream Trigger Molecules of Toll-Like ReceptorsPathway and Inflammatory Response LPS would activatedistinct pathway to induce inflammatory response via Toll-like receptors cascades and Lbp and Cd14 are key upstreammolecules that are common to all TLRs [43] Fortunatelyour study in vivo demonstrated that the therapy of CQCQDsignificantly decreased the levels of sera amylase and plasmaLPS Lbp and Cd14 compared to that in SAP group (Table 3)which suggested that the therapy of CQCQD could attenuatethe increase in the upstream trigger molecules caused bySAP complicated by endotoxemia The activation of Toll-likereceptors cascades would induce the upregulation of p-Src tophosphorylate p85120572 and induce the activation of Akt (kinaseSerinethreonine-protein) which ultimately leads to the acti-vation of NFKB and MAPK cascades and initiates the exces-sive transcriptions of proinflammatory cytokines [44 45] c-Fos is a key transcription factor in MAPK cascade whoseoverexpression would also mediate the numerous transcrip-tions of inflammatory cytokines [46] These previous reportshave been confirmed by our in vitro studies results that inhi-bitions of LPS-mediated high expressions of p-Src p-p85120572and c-Fos could suppress LPS-induced proinflammatorycytokines release (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion Strikingly the pretreatment ofCQCQD imitated the actions of these selective inhibitionsagents to inhibit LPS-mediated high expressions of p-Src p-p85120572 and c-Fos therefore suppressing the proinflammatorycytokines release (Figure 4 and Table 6) It is well known thatthe increase in proinflammatory cytokines release will lead tothe enhancement of the albumin leakage induced by LPSOurstudy in vitro provided the important evidences that therewere also remarkably positive correlations between LPS-induced proinflammatory cytokines release and paracellularleakage (Figure 5(d)) which suggested that the pretreatmentof CQCQD could probably contribute to alleviating LPS-induced paracellular leakage via inhibiting proinflammatorycytokines release (Table 4)

Protections and Maintenance of AJs TJs and the Homeosta-sis of F-Actin LPS-stimulated HUVECs had significantlyinduced the upregulated expressions of p-Src p-p85120572 and c-Fos (Figure 4) which would probably induce the disassemblyof AJs TJs and F-actin at cell-cell contact sites and trigger theexcessive reassembly of F-actin and cytoskeleton reorganiza-tion The molecular mechanisms were described as follows(1) the high expressions of p-Src at Tyr-419 would increasekinase activity to phosphorylate downstreammolecules [47]which would probably induce (a) the high phosphorylationof p85120572 to aggrandize the Akt (Serinethreonine-proteinkinase) activation to mediate the reorganization of cytoskele-ton [48] (b) the Tjp1 Tyr hyperphosphorylation to mediatethe collapse of TJs [49] and (c) the high phosphorylationof Ctnnb1 (Catenin beta-1) and Ctnnd1 (Catenin delta-1) toinduce disassembly of AJs [50 51] (2) the high expressionsof p-p85120572 would enhance Akt activity to induce cytoskeletonreorganization [48] (3) the excessive reassembly of F-actinwould further induce the overexpression and activation

of Fos [52] which would mediate more transcriptions ofinflammatory cytokines thus forming a vicious cycle Theseinferences have been confirmed by the studies in vitro thatLPS-stimulated HUVECs have markedly caused the decreasein TEER as well as the increase in proinflammatory cytokinesrelease and paracellular leak (Table 6) Notably the studies invitro have provided the key evidences that inhibitions of LPS-mediated high expressions of p-Src p-p85120572 and c-Fos couldreverse LPS-induced decrease in TEER and the increase inparacellular leak (Figures 4 5(a) 5(b) and 5(c) and Table 6)and the specific analyses have been demonstrated in the firstparagraph of the Discussion More notably the pretreatmentof CQCQD imitated the actions of these selective inhibitionsagents of these 3 predicted target proteins to inhibit LPS-induced high expressions of p-Src p-p85120572 and c-Fos (Fig-ure 4) Consistent with this the pretreatment of CQCQD evi-dently reversed LPS-induced decrease in TEER as well as theincrease in proinflammatory cytokines release and paracel-lular leak (Table 6) which suggested that the pretreatment ofCQCQDonLPS-stimulatedHUVECs could probably protectand maintain AJs TJs and the homeostasis of F-actin

To further verify the therapeutical effect of CQCQDon rats with SAP endotoxemia-induced ALI our studyprovided the key evidences that in in vivo study the therapyof CQCQD significantly ameliorated the enhancements ofsystemic and pulmonary albumin leakage as well as thedepravation of airways indicators (Tables 4 and 5) and ulti-mately improved respiratory dysfunction and pancreatic andpulmonary histopathological changes (Table 4 and Figure 3)

In conclusion the therapy of CQCQD could alleviatethe LPS- and cytokine-mediated pulmonary albumin leakagewhich were mainly via inhibiting the upregulation of p-Srcp-p85120572 and c-Fos
