摘要: 探讨益气法制剂(黄芪、白术)对CCL4所致肝纤维化大鼠的治疗作用及作用机制。采用腹腔注射40%四氯化碳(CCL4)玉米油溶液联合高脂低蛋白饮食建立肝纤维化模型大鼠。成模后分别给予相应药物灌胃治疗12周。HE、Masson染色法观察肝组织形态学变化,生化分析法检测血清肝功能,酶联免疫吸附法(ELISA)检测血清胶原蛋白含量。RT-qPCR检测肝组织内TGF-β1、TβRⅠ、Smad3、Samd7、α-SMA、HGF mRNA表达。给药治疗后,益气法制剂和秋水仙碱均可减轻大鼠胶原沉积,并可改善大鼠肝功能,其机制与抑制TGF-β1/Smad信号通路有关。

Abstract: To investigate the therapeutic effect and mechanism of Qi-Tonifying Decoction (Astragalus membranaceus and Atractylodes macrocephala) on hepatic fibrosis induced by CCL4 in rats.Hepatic fibrosis model was established by intraperitoneal injection of 40% carbon tetrachloride (CCL4) corn oil solution combined with high fat and low protein diet.The drugs were given to each group for 12 weeks.HE and Masson staining were used to observe the morphological changes of hepatic tissues.Biochemical analysis was used to detect liver function in serum.Enzyme-linked immunosorbent assay(ELISA) was used to detect collagen content in serum.The expression of TGF-beta 1,T beta R I,Smad3,Samd7,alpha -SMA and HGF in liver tissue was detected by RT-qPCR.After administration,Qi-Tonifying decoction and colchicine could reduce collagen deposition and improve liver function in rats,and its mechanism is related to inhibiting TGF-beta 1/Smad signaling pathway.

Key words: Qi-Tonifying, Hepatic fibrosis, CCL4, TGF-β1/Smad signaling pathway
