Objective:To observe the preventive and control effect of matrine on transforming growth factor (TGF-β1) and hepatocyte growth factor(HGF) of liver fibrosis tissue in rats.Methods:A total of 48SD rats were randomly divided intoA,B,C,D groups with12 in each, groupA as the normal control group and groupsB,C,D as liver fibrosis models using composite modulus method with carbon tetrachloride(CCL4).GroupB was the model group, groupC adoptedγ- interferon lavage therapy in the second day of modeling, and groupD adopted matrine lavage treatment, at4 and 8 weeks after treatment.Six rats were executed for detection ofTGF-β1 andHGF, liver tissue histology and comparison fibrosis degree changes of rat liver tissue between groups.Results:GroupsB,C,D showed a more significantly increasedTGF-β1 ateach time point compared with groupA(P<0.05);GroupB showed a more significantly increasedTGF-β1 than groupsC andD at weeks4 and8(P<0.05); groupD showed a lowest level ofTGF-β1, followed by groupsC and B.HGF of groupB decreased more significantly thanA group at weeks4 and8(P<0.05);HGF of groupsC andD was significantly elevated at4 and8 weeks than groupsA andB(P<0.05), in which the groupD showed the highest level ofHGF.According to tissue histologic observation, rat liver tissue structure of groupA was clear and normal, tissue structure of groupB was destroyed with obvious fibrous tissue hyperplasia and fatty change of hepatic cells; groupsC andD showed a slighter liver tissue damage, cell necrosis and connective tissue hyperplasia in collect abbacy than groupB with a trend of obvious improvement.Conclusions:Matrine can reduceTGF-β1 expression and enhance the activity ofHGF, so as to realize the inhibition effect on liver fibrosis in rats.
