ABSTRACT
Objective To investigate the effects of Qishen Erlian Decoction on serum MMP-1 and TIMP-1 levels in thioacetamide (TAA) induced liver fibrosis rats; To discuss its mechanism of action. Methods Liver fibrosis model was created by the TAA gavage method. 120 SD male rats were randomly assigned to control group, model group, colchicine group, Qishen Erlian Decoction low-, medium- and high-dose group (20 in each group). Each medication group was given relevant medicine for gavage. Control group and model group were given the same amount of normal saline for gavage, once a day for 5 weeks. HE staining and Masson trichrome staining were used to observe the pathological changes in liver tissue and liver tissue damage. Biochemistry, radioimmunoassay, and ELISA were used to detect the serum liver function, hepatic fibrosis index, MMP-1 and TIMP-1 levels. Results Compared with the model group, serum ALT, AST, TBIL, γ-GGT, HA, LN, Ⅳ-C and PCⅢ levels, MMP-1 and the ratio of MMP-1/TIMP-1 increased significantly and level of TIMP-1 decreased significantly in Qishen Erlian Decoction groups, with statistical significance (P<0.05, P<0.01). And there is a certain dose-effect relationship, with Qishen Erlian Decoction high-dose group the best effect. Conclusion Qishen Erlian Decoction can improve the liver function and liver fibrosis indexes, regulate the level of MMP-1 and TIMP-1, and prevent the progression of liver fibrosis.
ABSTRACT
Objective To observe the clinical efficacy ofQishen Erlian Decoction combined with entecavir for patients with liver fibrosis of hepatitis B.MethodsTotally 74 patients were divided into treatment group (38 cases) and control group (36 cases). The control group was given entecavir, while treatment group was given Qishen Erlian Decoction combined with entecavir, 48 weeks for 1 course. Entecavir was given to both groups after treatment, and two groups were followed up for 24 weeks. The liver function, DNA-HBV, serum TGF-β1, BMP-7, liver fibrosis indexes and clinical symptom changes of the two groups were observed.Results 3 cases were excluded and 3 cases were lost during follow-up in treatment group; 6 cases were lost during follow-up in the control group. Liver function and HBV-DNA in 12, 24, 36, 48 weeks and 24 weeks in follow-up were significantly lower than those pre-treatment (P<0.01) in the treatment group, and were significantly better than those in the control group (P<0.01). TGF-β1 decreased (P<0.05), BMP-7 increased (P<0.01), and the ratio of TGF-β1/BMP-7 decreased (P<0.01) in both groups after treatment. There was significant difference between the two groups (P<0.05). HA, LN, PCⅢ,Ⅳ-C, and FS decreased significantly in treatment group after treatment and in the follow-up (P<0.01), fatigue, discomfort in liver region, disgust oil and anorexia were improved (P<0.05), the difference was significant compared with control group (P<0.05).Conclusion Qishen Erlian Decoction combined with entecavir can not only protect liver and reduce aminotransferase, but also be antiviral and reverse liver fibrosis.
ABSTRACT
Objective To investigate the effects of annonaceous acetogenin on proliferation and apoptosis in Raji cells and its mechanism.Methods Raji cells cultured in vitro were divided into control group,annonaceous acetogenin group and adriamycin group.Raji cells were effected by 6.25,12.5,25,50 ?g/mL annonaceous acetogenin.Proliferation of Raji cells were evaluated by MTT assays,apoptosis percentage was assessed by flow cytometry.Caspase-9 protein was detected by immunohistochemistry.Results The Raji cell proliferation rate of annonaceous acetogenin decreased compared with the control,that of 25,50 ?g/mL group were lower than adriamycin group,and it was related to the concentration,relying on the incubating time.The apoptosis rate was higher than control,that of 25,50 ?g/mL group were higher than adriamycin group,and it was related to the concentration and the incubating time.The expression of caspase-9 protein of annonaceous acetogenin group was higher than control,and it had a positively relationship with the concentration and incubating time.Conclusions Annonaceous acetogenin could inhibit cell proliferation in a dose-dependent and time-dependent manner in Raji cells,and it may induce Raji cells apoptosis by up-regulating caspase-9 expression.
