摘要 目的研究白藜芦醇(Res)对胶原诱导性关节炎(CIA)大鼠成纤维样滑膜细胞(FLS)增殖的影响并探讨其可能的作用机制。方法应用四甲基噻唑氮蓝(MTT)比色法和流式细胞术(FCM)检测FLS的增殖水平和细胞周期分布。结果50~400μmol/L的Res作用24、48h和25~400μmol/L的Res作用72h,均能明显抑制FLS的增殖(P<0.05),且具有时间剂量依赖性。细胞周期分析显示与对照组比较,Res处理组的FLS的S期细胞所占百分比例明显增加(P<0.01);G2/M期细胞所占百分比例明显减少(P<0.01),并呈剂量依赖性。结论Res对CIA大鼠成纤维样滑膜细胞具有生长抑制作用,其抗增殖效应呈现一定的剂量、时间依赖方式。该作用可能与Res能够使FLS的细胞周期阻滞于S期有关。
