复方861对肝星状细胞的增殖和凋亡的干预作用
Proliferation and apoptosis of hepatic stellate cells and effects of compound 861 on liver fibrosis
【摘要】 目的研究HSC在体外和体内的增殖和凋亡及中药的干预作用。方法体外研究对象为HSC系。细胞增殖采用MTT比色法,细胞凋亡采用电镜观察、流式细胞仪和TUNEL法检测。临床研究对象是慢性乙型肝炎患者。结果复方861显著抑制体外培养的HSC增殖,随着药物剂量的增加和时间的延长,HSC的凋亡明显增多,凋亡率增加,呈剂量和时间依赖。 TUNEL法检测,用 5 mg/ml复方 861作用 48 h后, HSC凋亡率为 25.9%,对照组为9.2%,差异有显著性。在慢性乙型肝炎患者中,肝星状细胞大量活化增生。复方861治疗6个月后,活化的星状细胞数量显著减少,可观察到其凋亡。结论活化的肝星状细胞存在凋亡,促进其凋亡在肝纤维化治疗中有重要作用。
【Abstract】 Objective To investigate the proliferation and apoptosis of the hepatic stellate cell (HSC) in vitro and in vivo and the effects of Chinese herb, compound 861. Methods The in vitro study was carried out on the culture of hepatic stellate cell line. Various concentrations of compound 861 were added and incubated. Cell proliferation was detected with MTT colorimetric assay. Cell apoptosis was detected by electron microscopy, flow cytometry and TUNEL. The subjects of in vivo study were patients with chronic hepatitis B. Results Compound 861 could significantly inhibit HSC proliferation and increase the apoptosis rate of HSC dose-dependently and time-dependently compared with the control group. After compound 861 incubation for 48h, the apoptosis rate of HSC was 25.9% compared with 9.2% in control group(p<0.05). The clinical study elucidated that the HSC was activated and proliferated in patients with chronic hepatitis B. After compound 861 treatment for 6 months, the number of activated HSC decreased and the apoptosis of HSC could be seen in the liver biopsy. Conclusion Apoptosis of activated HSC exists in vitro and in vivo, stimulating its apoptosis may play an important role in the treatment of liver fibrosis.
