Therapeutic effect of Qingyi decoction in severe acute pancreatitis-induced intestinal barrier injury

World Journal of Gastroenterology 2015年第12期21卷 3537-3546页

作者： Jing-Wen Zhang Gui-Xin Zhang Hai-Long Chen ge-liang liu Lawrence Owusu Yu-Xi Wang Guan-Yu Wang Cai-Ming Xu Department of Surgery The First Affiliated Hospital Dalian Medical University Department of Surgery The Second Affiliated Hospital Dalian Medical University

AIM: To investigate the effect of Qingyi decoction onthe expression of secreted phospholipase A2(s PLA2) in intestinal barrier ***: Fifty healthy Sprague-Dawley rats were randomly divided into control, severe acute pancreatitis(SAP), Qingyi decoction-treated(QYT), dexamethasonetreated(DEX), and verapamil-treated(VER) groups. The SAP model was induced by retrograde infusion of 1.5% sodium deoxycholate into the biliopancreatic duct of the rats. All rats were sacrificed 24 h post-SAP induction. Arterial blood, intestine, and pancreas from each rat were harvested for investigations. The levels of serum amylase(AMY) and diamine oxidase(DAO) were determined using biochemical methods, and serum tumor necrosis factor(TNF)-α level was measured by an enzyme linked immunosorbent assay. Pathologic changes in the harvested tissues were investigated by microscopic examination of hematoxylin and eosinstained tissue sections. The expressions of s PLA2 at m RNA and protein levels were detected by reverse transcriptase PCR and Western blot, respectively. A terminal deoxynucleotidyl transferase-mediated d UTP nick-end labeling assay was used to investigate apoptosis of epithelial cells in the intestinal tissues. RESULTS: Compared to the control group, the expression of s PLA2 at both the m RNA and protein levels increased significantly in the SAP group(0.36 ± 0.13 vs 0.90 ± 0.38, and 0.16 ± 0.05 vs 0.64 ± 0.05, respectively; P s < 0.01). The levels of AMY, TNF-α and DAO in serum were also significantly increased(917 ± 62 U/L vs 6870 ± 810 U/L, 59.7 ± 14.3 ng/L vs 180.5 ± 20.1 ng/L, and 10.37 ± 2.44 U/L vs 37.89 ± 5.86 U/L, respectively; P s < 0.01). The apoptosis index of intestinal epithelial cells also differed significantly between the SAP and control rats(0.05 ± 0.02 vs 0.26 ± 0.06; P < 0.01). The serum levels of DAO and TNF-α, and the intestinal apoptosis index significantly correlated with s PLA2 expression in the intestine(r = 0.895, 0.893 and 0.926, respectively; Ps
