摘 要:目的:研究中药舒肝颗粒对体外培养活化大鼠肝星状细胞(HSC)活化增殖的影响,探讨舒肝颗粒抗肝纤维化的作用机制。方法:用空白对照及0.01,0.02,0.04 g.L-1的舒肝颗粒分别处理HSC细胞系HSC-T6 24 h后,MTT比色法检测细胞增殖,光镜下观察HSC形态学变化,免疫组化法测各组α-平滑肌肌动蛋白(α-SMA)表达的变化。结果:舒肝颗粒作用HSC细胞24 h后,0.01,0.02,0.04 g.L-1终浓度肝星状细胞抑制率分别为7.02%,13.33%,20.85%,明显高于空白对照组,且与药物浓度相关。与对照组比较,随着舒肝颗粒药物浓度的增高,HSC的细胞增殖和胞体伸展受到明显抑制;空白对照组,舒肝颗粒0.01,0.02,0.04 g.L-1组α-SMA阳性表达率分别为(62.83±3.42)%,(47.31±2.74)%,(37.79±3.01)%,(25.74±2.83)%,各组与空白对照组相比较差异有统计学意义(P<0.05)。结论:舒肝颗粒抑制肝星状细胞活化、增殖并抑制α-SMA表达,可能是其抗纤维化的作用机制。Objective:To study effect of Shugan granule on proliferation and activation of rat hepatic stellate cells in vitro and investigate the main mechanism of Shugan granule in protection of liver fibrosis.Method: The experiment was divided into the blank control group,Shugan granule 0.01 g·L-1 group,Shugan granule 0.02 g·L-1 group and Shugan granule 0.04 g·L-1 group.HSC was intervented in vitro for 24 h,then cell proliferation were found by MTT,the morphological changes were detected,α-smooth muscle actin(α-SMA) expression was investigated by Immunohistochemical method.Result: After 24 hours of incubation,Shugan granule at concentrations of 0.01,0.02,0.04 g·L-1 reduced the rates of cell growth by 7.02%,13.33%,20.85%,respectively,showing inhibitory effects with concentration-dependent manner.Compared with the control group,cell proliferation and cell body extension was obviously inhibited by Shugan granule,the positive rate of expressed α-SMA in control group was(62.83±3.42)%,in Shugan granule 0.01 g·L-1 group was(47.31±2.74)%,in Shugan granule 0.02 g·L-1 group was(37.79±3.01)%,in Shugan granule 0.04 g·L-1 group was(25.74±2.83)%,among control group and three Shugan granule intervention group there was a significant difference(P0.05).Conclusion:Shugan granule can resist hepatic fibrosis through inhibiting the activation and prolifition of HSC.
