摘要 目的通过检测Toll样受体4(TLR4)和核因子E2相关因子2(Nrf2)在子宫脱垂患者骶韧带组织中的表达,阐释氧化应激破坏天然免疫在子宫脱垂发生中的作用。方法实验分为子宫脱垂组、子宫内膜异位症组及对照组,分别于术中切取三组患者部分骶韧带组织,通过RT-PCR和免疫组化两种方法检测TLR4和Nrf2基因和蛋白的表达,并比较其在各组的差异。结果 TLR4在子宫脱垂组的表达高于正常组(P<0.05),在对照组的表达高于子宫内膜异位症组(P<0.05);而Nrf2在子宫脱垂组中的阳性表达率低于对照组(P<0.05),在正常对照组中的表达低于子宫内膜异位症组(P<0.05)。结论 TLR4可能通过强化机械力诱发的氧化应激反应对宫颈筋膜环有机械力刺激作用;而Nrf2对这种氧化应激形成的刺激有一定的保护作用,这两个因子的异常表达与子宫脱垂的发生相关。
