Network Pharmacology Research of Qingyi Decoction(清胰汤)in the Treatment of Acute Pancreatitis

Presently,clinically specific drugs are absent for acute pancreatitis(AP).Numerous clinical investigations have extolled the notable efficacy of Qingyi Decoction(QYD,清胰汤)in the management of AP.However,the molecular mechanisms are lacking.Therefore,we analyzed pharmacological mechanisms of QYD in treating AP through network pharmacology.As for the network pharmacology,173active compounds and 1,073 active target genes for QYD were identified.Of these,884 active target genes correlated with AP among the 11128 AP-associated genes and were linked to the 173 active compounds.In addition,GO functional enrichment and KEGG pathway enrichment revealed that these target genes were mainly enriched in cancer signaling,neuroactive ligand-receptor interactions,lipids and atherosclerosis,cAMP signaling,central carbon metabolism in cancer,and calcium signaling pathways.Finally,molecular docking was employed to assess the binding affinity between target proteins and their associated compounds.This study identified critical compounds and potential target genes.Our study may serve as a foundation for subsequent investigations on the therapeutic potential of QYD in treating AP.

Qingyi decoction attenuates intestinal epithelial cell injury via the calcineurin/nuclear factor of activated T-cells pathway

BACKGROUND Recent studies have demonstrated that dysfunction of the intestinal barrier is a significant contributing factor to the development of severe acute pancreatitis(SAP).A stable intestinal mucosa barrier functions as a major anatomic and functional barrier,owing to the balance between intestinal epithelial cell(IEC)proliferation and apoptosis.There is some evidence that calcium overload may trigger IEC apoptosis and that calcineurin(CaN)/nuclear factor of activated Tcells(NFAT)signaling might play an important role in calcium-mediated apoptosis.AIM To investigate the potential mechanisms underlying the therapeutic effect of Qingyi decoction(QYD)in SAP.METHODS A rat model of SAP was created via retrograde infusion of sodium deoxycholate.Serum levels of amylase,tumor necrosis factor(TNF-α),interleukin(IL)-6,D-lactic acid,and diamine oxidase(DAO);histological changes;and apoptosis of IECs were examined in rats with or without QYD treatment.The expression of the two subunits of CaN and NFAT in intestinal tissue was measured via quantitative realtime polymerase chain reaction and western blotting.For in vitro studies,Caco-2 cells were treated with lipopolysaccharide(LPS)and QYD serum,and then cell viability and intracellular calcium levels were detected.RESULTS Retrograde infusion of sodium deoxycholate increased the severity of pancreatic and intestinal pathology and the levels of serum amylase,TNF-α,and IL-6.Both the indicators of intestinal mucosa damage(D-lactic acid and DAO)and the levels of IEC apoptosis were elevated in the SAP group.QYD treatment reduced the serum levels of amylase,TNF-α,IL-6,D-lactic acid,and DAO and attenuated the histological findings.IEC apoptosis associated with SAP was ameliorated under QYD treatment.In addition,the protein expression levels of the two subunits of CaN were remarkably elevated in the SAP group,and the NFATc3 gene was significantly upregulated at both the transcript and protein levels in the SAP group compared with the control group.QYD significantly restrained CaN and NFATc3 gene expression in the intestine,which was upregulated in the SAP group.Furthermore,QYD serum significantly decreased the LPS-induced elevation in intracellular free Ca^(2+)levels and inhibited cell death.CONCLUSION QYD can exert protective effects against intestinal mucosa damage caused by SAP and the protective effects are mediated,at least partially,by restraining IEC apoptosis via the CaN/NFATc3 pathway.

Analysis of Clinical Effect of Wumen Qingyi Decoction on Acute Pancreatitis

[Objectives]To examine the effects of Wumen Qingyi Decoction on inflammatory responses in patients with acute pancreatitis(AP).[Methods]Eighty patients with mild or severe AP were randomly allocated to a treatment group(Wumen Qingyi Decoction+baseline treated)or a control group(baseline treated).All patients were managed conservatively.In addition,the Group A received Wumen Qingyi Decoction for 400 mL/d for 7 d.Laboratory parameters,condition of disease and therapeutic effect indexes,and so on,between the two groups were compared.[Results]The recovery of serum levels of amylase(AMS),C reaction protein(CRP),and tumor necrosis factor(TNF-α),interleukin1(IL-1),IL-6,IL-10,as well as the scores of Balthazar and BISAP in Treatment group were quicker than those in Control group(P<0.05).In addition,the improvement of organic dysfunction in Treatment group was better than that in Control group.[Conclusions]The course of combined Wumen Qingyi Decoction and basic treatment of western medicine could effectively adjust the body's inflammatory response to promote the recovery process of acute pancreatitis.

Research Progress of Qingyi Decoction(清胰汤)in Treating Acute Pancreatitis

Acute pancreatitis(AP)is one of the most common digestive system diseases.AP is associated with high rate of hospitalization and death risk,but it lacks specific and effective therapies.Qingyi Decoction(清胰汤)is the basic formula for AP treatment.Qingyi Decoction can improve symptoms,inhibit inflammatory,ameliorate AP-induced organ injury via multiple pathways and targets,as demonstrated in many preclinical and clinical studies.This review summarized the progress of the clinical studies and mechanisms of Qingyi Decoction,aimed to provide valuable research information for the future clinical application and molecular mechanism research of Qingyi decoction.

Synergetic Effect of Yihuo Qingyi Decoction (益活凊胰汤) and Recombinant Staphylokinase in Treatment of Severe Acute Pancreatitis of Rats

Objective: To investigate the effect of recombinant staphylokinase (r-Sak) and the Chinese medicine Yihuo Qingyi Decoction (益活凊胰汤 Herbal decoction for severe acute pancreatitis) in the treatment of the severe acute pancreatitis (SAP) in rats, and to observe the synergistic effect of the two. Methods: One hundred and sixty-two adult male SD rats with the body mass of 250–280 g were randomly divided into the following 5 groups: sham operation group (n=18), control group (n=36), Yihuo Qingyi Decoction treatment group (n=36), r-Sak treatment group (n=36), and Yihuo Qingyi Decoction plus r-Sak treatment group (n=36). The SAP ratmodel was prepared by retrograde injection of 5% sodium taurocholate into the cholangiopancreatic duct. Two days before modeling, Yihuo Qingyi Decoction was intragastrically administrated, and r-Sak was intraperitoneally injected. The survival rate within 18 h after modeling was determined. The pancreatic blood flow, the weight of ascites, and the serum amylase and lipase were investigated at 6 h, 12 h, and 18kh after modeling, and the pancreatic tissue was examined under light microscopy to see its pathological change. Results: The 18 h survival count of group A,B,C,D and E rats was 9,2,6,7 and 8 respectively. After r-Sak and Yihuo Qingyi Decoction intervention, the serum amylase and lipase and the weight of ascites were significantly decreased, especially in group E.18 h after modeling, the level of the serum amylase and lipase and the weight of ascites in group E was 1 100±118 U·L-1,1 000±150 U·L-1 and 13.40±1.80 g respectively, obviously lower than that of group B (P<0.05).After SAP was induced, the pancreatic blood flow showed a tendency to decrease, but the decrease extent in the treatment groups was smaller than that in the control group.18h after modeling, the pancreatic blood flow in group B and group E was 30.16±8.96 mL·100 g-1·min-1,and 129.10±42.58 mL·100 g-1·min-1 respectively, there was significant difference (P<0.05). The pathological change of the pancreatic tissue was alleviated in the treatment groups. Conclusion: Both r-Sak and Yihuo Qingyi Decoction play a beneficial role in the treatment of rat SAP and there is a synergistic effect between the two.
