OBJECTIVE: To explore the preventive effects of Jiawei Yinchen Sini Decoction on the gene expression of Smad7 and Collagen,Ⅲ in mice with hepatic fibrosis.
METHODS: 48 male ICR mice were randomly divided into normal group, model group, colchicine group, JWYSN high dose group, medium dose group and low dose group, with 8 mice in each group. The hepatic fibrosis model was established by intraperitoneal injection of 30% CCl4( 1. 5 mg/kg, dissolved in olive oil). At the same time, the mice were treated with intragastric adminstration of drugs. After 14 days, the liver index was calculated; the levels of serum hyaluronic acid( HA) and laminin protein( LN) were detected by Enyme-linked immunosorbent assay; the pathological fibrosis change was observed by performing HE staining and was made a grading of hepatic fibrosis. mRNA expression of Smad7 and Collagen I, Ⅲ were detected by RT-q PCR analysis.
RESULTS: (1) Compared with model group, the liver index and levels of HA and LN in JWYSN medium dose group and low dose group were obviously decreased( P < 0. 05).( 2) The pathological results showed that, compared with model group, the hepatic fibrosis were significantly relief in different dose of JWYSN group( P < 0. 05).( 3) The expressions of Collagen Ⅰ mRNA in each treatment group were significantly lower than model group( P < 0. 05); In addition to JWYSN high dose group, the expressions of Smad7 mRNA in each treatment group increased significantly( P < 0. 05); In addition to JWYSN low dose group, the expression of CollagenⅢmRNA in each treatment group decreased significantly( P < 0. 05).
CONCLUSION: Jiawei Yinchen Sini decoction can up-regulate the expressions of Smad7 mRNA and inhibit expressions of mRNA and CollagenⅢmRNA in mice with hepatic fibrosis,thus attenuate the development of hepatic fibrosis.
