摘要：

目的:观察三七总皂苷(PNS)对小鼠巨噬细胞炎性反应的治疗作用,同时探讨其可能机制。方法:通过蛋白质免疫印迹实验、实时PCR法、酶联免疫吸附试验,对照研究PNS对小鼠巨噬细胞系RAW 246.7细胞中炎性反应调控因子过氧化物酶体增殖物激活受体-α(PPAR-α)以及其下游调控的炎性反应递质肿瘤坏死因子-α(TNF-α)、C反应蛋白(CRP)和重组人巨噬细胞集落刺激因子(M-CSF),白细胞介素6(IL-6),炎性反应相关氧化因子诱导型一氧化氮合酶(iNOS)和环氧化酶-2(COX-2)表达的影响。结果:小鼠巨噬细胞炎性反应模型制备后TNF-α、CRP、M-CSF、IL-6、iNOS及COX-2水平明显上调,三七总皂苷给药后,细胞炎性反应递质与造模组比较有显著降低,差异有统计学意义(P<0.05)。结论:三七总皂苷可明显抑制小鼠巨噬细胞炎性反应效应,其作用机制可能通过激活调控因子PPAR-α实现。
