摘要(Abstract):
目的探讨丹参酮ⅡA对脓毒症大鼠外周血CD4+T细胞的作用。方法采用盲肠结扎穿孔术制备脓毒症大鼠模型(CLP),给予丹参酮ⅡA(TanⅡA)处理,分别于治疗前及治疗后24、48、72 h各时间点取静脉血,流式细胞仪检测全血细胞中辅助性T细胞(Th1、Th2、Th17);采用酶联免疫吸附法(ELISA)测定血中白细胞介素-1(IL-1)、白细胞介素-10(IL-10)、白细胞介素-17(IL-17)及肿瘤坏死因子-α(TNF-α)水平。结果 CLP组大鼠血清TNF-α、IL-17、IL-1水平和Th17比例明显高于同期Sham组(P<0.05),而TanⅡA各亚组血清TNF-α、IL-17、IL-1水平和Th17比例均低于CLP同期各亚组(P<0.05);CLP组大鼠血清IL-10水平和Th1/Th2比值明显低于Sham组(P<0.05),而TanⅡA各亚组血清IL-10水平和Th1/Th2比值高于CLP同期各亚组(P<0.05)。结论丹参酮ⅡA可能通过作用于脓毒症大鼠的外周血CD4+T细胞发挥调节免疫、改善炎症反应的作用。
