ABSTRACT
Objective To observe the effect of JWSNS serum on proliferation and apoptosis hepatic stellate cells.Methods After being added different concentrations of JWSNS (the low concentrations of JWSNS:0.78 g/ml of crude drug; the medium concentration group of JWSNS:1.56 g/ml of crude drug; the high concentration group of JWSNS:3.12 g/ml of crude drug) drug-containing serum in vitro HSC-T6 cells for 12h,24 h and 48 h respectively,detected serum HSC-T6 proliferation with MTT colorimetry method and measured HSC-T6 apoptosis with flow cytometry and TUNEL method.Results (①) After applied JWSNS on rats HSC-T6,the Cell proliferation was inhibited which showed a time-concentration dependence.The differences were significant when comparing each JWSNS group with the control group (P＜0.01).High concentration of JWSNS group showed significant difference when compared with Biejiaruangan tablets group (P＜0.05) with high concentration of JWSNS (0.399± 0.041) ％ after 48h,and Biejia-Ruangan tablets (0.429± 0.037) ％ after 48 h.② Flow cytometry analysis showed each JWSNS group and Biejiaruangan tablets group had significant increased cell apoptosis when compared with the control group (P＜0.05) after 12 h,24 h,and 48 h.JWSNS medium concentration group [12 h was (17.83±0.25)％,24 h was (26.06±0.26)％,48 h was (39.30±2.25) ％] and JWSNS high concentration group [12 h was (27.15±0.29)％,24 h was (38.96±0.51)％,48 h was (49.34± 0.77) ％] had a significant increased cell apoptosis compared to the Biejia-Ruangan tablets group [ 12 h was (8.31 ± 0.30) ％,24 h was (16.25 ± 0.25) ％,48 h was (27.12± 0.39) ％].③ TUNEL detection showed that each concentration of JWSNS group [the low concentration of JWSNS:was (25.1 ± 1.48)％,medium concentration group of JWSNS was(39.30±2.25)％,high concentration group of JWSNS was(39.30±2.25)％] had a significant increased cell apoptosis rate than Biejiaruangan tablets group (30.0± 3.92) after 48 h (P＜0.01).Conclusion JWSNS containing serum can inhibit the proliferation of HSC-T6 in vitro,promote the apoptosis
ABSTRACT
Objective To investigate the role of Jiawei-sini Dection on expression of rat transforming growth factor-β1 receptor Ⅰ,Ⅱ(TβRⅠ,TβR Ⅱ), and study its treatment of anti-HF and the possible mechanisms. Methods The model of rat hepatic fibrosis was setup by subcutaneous injection of carbon tetrachloride and drinking alcohol freely;According to random block method, the successful model rats were divided into three groups:pathological model group (group B),Fufangbiejiarangan tablet group (group C), and Jiawei Sini Decoction group (group D), each group containing ten rats. Group A and group B were given two milliliters saline, group C was given Fufangbiejiarangan tablets 0.625 grams per kilogram of body weight, group D was given Jiawei Sini liquid 15.625 grams per kilogram of body weight.Each rat was fed once a day for 8 weeks.In order to avoid the natural repair of the hepatic affecting the experimental results, the rats,except group A, were still injected 40% CCl4 three milliliters per kilogram of body weight after feeding drug once a week. Fufang-Biejia-Ruangan Ttablet group was set as a positive control;The effects on expression of TβRⅠ,TβR Ⅱ were determined by immunohistochemical method. Changes of alanine aminotransferase (ALT), aspartate aminotransferase(AST),alkaline phosphatase(ALP) and TβRⅠ,TβR Ⅱ were observed in rats. Results The expression of TβRⅠ、Ⅱ, compared with the pathological model(16.63±2.69)%, (14.57±1.09)%, were significantly reduced in Jiawei-Sini Dection group[they are(8.09±0.71)%,(6.51±0.48)%, the difference was statistically significant(P＜0.05).The effects of Jiawei-Sini Dection was equal to the effect of Fufang-Biejia-Ruangan Tablets on expression of TβRⅠ,TβR Ⅱ(P＞0.05). Conclusion Jiawei-Sini Dection was able to inhibit the expression of TβRⅠ and TβR Ⅱ, thus affected the combination of TGFβ1, and their receptors.
