摘    要:目的:观察穿山龙水溶性总皂苷对大鼠滑膜成纤维细胞系RSC-364细胞分泌基质金属蛋白酶-2(MMP-2)和MMP-9的影响。方法:应用肿瘤坏死因子-α(TNF-α)和白介素17(IL-17)刺激RSC-364细胞建立类风湿性关节炎细胞模型,并以不同剂量穿山龙水溶性总皂苷进行干预,ELISA法检测细胞培养液上清MMP-2和MMP-9的水平。结果:穿山龙水溶性总皂苷各剂量组(10、20、30mg/L)在不同时间点(24、48、72h)均可明显降低TNF-α和IL-17刺激的RSC-364细胞分泌MMP-2、MMP-9水平的升高,并呈剂量依赖性(P<0.05)。结论:穿山龙水溶性总皂苷可能通过抑制RSC-364细胞分泌MMP-2和MMP-9发挥抗类风湿性关节炎的作用。

关 键 词:穿山龙水溶性总皂苷  类风湿性关节炎  基质金属蛋白酶-2  基质金属蛋白酶-9  MMP-2  MMP-9

Abstract:Objective: To observe the inlfuence of water soluble total saponins of Dioscorea nipponica on rat synovial ifbroblast cell line RSC-364 cells secreting matrix metalloproteinases-2 (MMP-2) and MMP-9.Methods: Interleukin-17 (IL-17) and tumor necrosis factor-α (TNF-α) were used to stimulate RSC-364 for establishing rheumatoid arthritis (RA) cell model, then the cell model was intervened by water soluble total saponins of Dioscorea nipponica in different dosage. ELISA was used to detect the MMP-2 and MMP-9 level in cultural supernatants of RSC-364 cells.Results:Water soluble total saponins of Dioscorea nipponica in different dosage at different time point could obviously reduce the level of RSC-364 cells secreting MMP-2 and MMP-9 stimulated by IL-17+ TNF-α, and showed dosage-dependent (P〈0.05).Conclusions:Water soluble total saponins of Dioscorea nipponica may play a role in anti-RA by inhibiting RSC-364 cell secreting MMP-2 and MMP-9.
Keywords:Water soluble total saponins of Dioscorea nipponica  Rheumatoid arthritis
