摘　　要：目的:明确祛湿化瘀方对实验性非酒精性脂肪性肝炎(NASH)合并肝纤维化的疗效。方法:运用高反式脂肪酸高糖饮食诱导29周构建小鼠NASH合并肝纤维化模型,并予祛湿化瘀方灌胃给药4周,设奥贝胆酸为阳性对照药。观察各组小鼠血清丙氨酸氨基转移酶(ALT)及天门冬氨酸氨基转移酶(AST)活性、空腹血糖(FBG)、胰岛素(INS)和胰岛素抵抗指数(HOMA-IR)水平,肝组织甘油三酯(TG)与羟脯胺酸(HYP)含量,肝组织病理,肝纤维化相关指标:肝组织Ⅰ型胶原蛋白(Col-Ⅰ)、α-平滑肌肌动蛋白(α-SMA)和转化生长因子-β(TGF-β)的mRNA及蛋白的表达。结果:祛湿化瘀方可显著降低NASH肝纤维化小鼠血清ALT、AST活性及FBG、INS和HOMA-IR(P<0.01,P<0.05),降低肝组织TG及HYP含量(P<0.05,P<0.01);显著改善肝组织脂肪变性、炎症及气球样变、降低纤维化分期,显著降低肝组织Col-Ⅰ、α-SMA和TGF-β的mRNA及蛋白表达(P<0.05,P<0.01)。结论:祛湿化瘀方可改善实验性NASH肝纤维化,为其治疗NASH肝纤维化的临床应用及药物研发提供依据。Objective:To assess the therapeutic effect of a Qushi Huayu Formula(QSHY)on experimental non-alcoholic steatohepatitis(NASH)combined with liver fibrosis.Methods:A mouse model of NASH combined with liver fibrosis was induced by high trans-fatty acid and high sugar diet for 29 weeks.The mice were treated with QSHY by gavage for the last 4 weeks,and obeticholic acid was used as a positive control.The serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST)activity;fasting blood glucose(FBG),insulin(INS),and homeostatic model assessment for insulin resistance(HOMA-IR);triglyceride(TG)and hydroxyproline(HYP)content in liver tissue;the histopathological changes in liver tissues and related indicators of liver fibrosis were observed in each group of mice,such as the mRNA and protein expression of type I collagen(Col-Ⅰ),alpha-smooth muscle actin(α-SMA)and transforming growth factor-beta(TGF-β)were measured.Results:QSHY could significantly reduce serum ALT and AST activities,FBG,INS and HOMA-IR(P<0.01,P<0.05)and the contents of TG and HYP(P<0.05,P<0.01),improve the liver tissue pathology of mice,including steatosis,lobular inflammation,and ballooning.The mRNA and protein levels of Col-Ⅰ,α-SMA and TGF-βin liver tissue were significantly lower than those in the model group(P<0.05,P<0.01).Conclusion:Qushi Huayu Formula can improve liver fibrosis in experimental NASH,which provides a basis for its clinical application and drug development in the treatment of NASH complicated with liver fibrosis.
