Therapeutic effects of Chai Qin Cheng Qi decoction on severe acute pancreatitis complicated liver damage in rats and its mechanisms

Abstract

To study the effects of Chai Qin Cheng Qi Decoction(CQCQD)(Traditional Chinese Medicine)on severe acute pancreatitis (SAP)complicated liver damage in rats. Seventy-two SD rats were randomly divided into three groups(n=24):Sham group, SAP group and CQCQD treatment group. SAP model was induced by retrograde injection with sodium taurocholate. The rats in CQCQD group received treatment with CQCQD. After modeling 1 h, 5 h, 10 h, pancreas and liver histopathological changes were observed. The serum levels of interleukin-6(IL-6), amylase(AMS), alanine aminotransferase(ALT) and aspartate transaminase(AST) were detected. IL-6 and monocyte chemotactic protein 1(MCP-1)mRNA in pancreas and liver were assayed. Compared with sham group, the activities of AMS,ALT and AST and the serum level of IL-6 in SAP group were increased significantly. The levels of MCP-1 and IL-6 mRNA in pancreas and liver tissue were increased (P<0.05). Compared with SAP group, the activities of AMS,ALT and AST and the level of IL-6 in CQCQD group were reduced significantly (P<0.05). The pancreas and liver tissue pathological damage alleviated. The levels of IL-6 and MCP-1mRNA in pancreas and liver were decreased significantly(P<0.05). MCP-1 takes part in the progression of SAP complicated liver damage; CQCQD can significantly inhibit the expression of pancreas and liver MCP-1, alleviate pathological damage of pancreas and liver in SAP and play a therapeutic role in SAP complicated liver damage.
