摘 要:目的 研究中药复方861对肝星状细胞NF-κB活性的影响。方法 将5mg/ml的复方861加入体外培养的大鼠肝星状细胞系作用48h。 NF-κB活性的检测采用凝胶电泳移动抑制法,细胞培养液中细胞因子的检测采用ELISA法,细胞凋亡采用流式细胞仪和TUNEL法检测。结果 复方861作用使体外培养的肝星状细胞NF-κB结合活性比未加药的空白对照组显著减弱,细胞培养液中的IL-6和sICAM水平减低(P<0.05),星状细胞凋亡增加(P<0.01)。结论 复方861显著抑制体外培养的肝星状细胞NF-κB活性可能为治疗肝纤维化中的重要机理之一。Objective: To investigate the effect of Cpd 861 on nuclear factor-kappa B (NF-kB) binding activity of hepatic stellate cells (HSC) in vitro. Methods The study was oboed out on the culture of hepatic stellate cell line, 5mg/ml of Cpd 861 was added and incubated for 48 hours. NF-κB binding activity was evaluated by electrophoretic mobility shift assays. IL-6 and sICAM-1 levels in the cultured supernatant were detected by ELISA. Cell apoptosis was detected by flow cytometry and TUNEL. Results Cpd 861 suppressed the binding activity of NF-kB in HSCs compared with the control group. Moreover, IL-6 and sICAM-1 levels in the cultured supernatant were decreased (P<0.05) and apoptosis rate of HSCs was increased after Cpd 861 incubation (p<0.01). Conclusions The inhibitory effect on NF-kB binding activity might be part of the cellular mechanism of Cpd 861 to treat liver fibrosis.
