摘　　要：Objective: Scutellarin is a primary active composition come from Erigeron breviscapus. It is well known that scutellarin has anti-infammatory and antioxidant physiological functions. In this study, we detected the effects of scutellarin on hepatocyte cell apoptosis in type 2 diabetes mellitus(T2DM) rats.Methods: Sprague Dawley(SD)(6–8 weeks, 160–180 g) rats were randomly divided into six groups: control, model, scutellarin low-dose, medium-dose, high-dose treatment, and rosiglitazone positive groups;with 10 SD rats in each group(n = 10). The changes of biochemical factors in serum were detected by automatic biochemical instrument, the pathological changes of liver tissue were detected by hematoxylin and eosin(HE) staining, the apoptosis of liver tissue and cells was detected by tissue staining and fow analyzer, and the expression of apoptosis-related factors were determined by q PCR, Western blot and immunohistochemistry in liver tissues or cells.Results: The results showed that scutellarin decreased the levels of fasting blood glucose, total cholesterol, triglyceride, and low-density lipoprotein and increased the levels of high-density lipoprotein.Meanwhile, scutellarin decreased the levels of alanine transaminase(ALT) and aspartate transaminase(AST) and improved liver function. In addition, scutellarin suppressed the secretion of interleukin-1(IL-1), interleukin-6(IL-6) and tumor necrosis factor-a(TNF-a) and reduced hepatocyte apoptosis.Furthermore, scutellarin inhibited the expression of cleaved Caspase-3, Bax, and cytochrome C(Cyt-C)and promoted the expression of Bcl-2.Conclusion: Scutellarin can inhibit the apoptotic pathway, thereby relieving T2DM.
