摘要
目的:通过研究感染性早产小鼠胎盘Toll样受体4(Toll-like receptor 4,TLR4),核转录因子-kappaB p65(Nuclear factor-kappaB p65,NF-κBp65)和肿瘤坏死因子α(Tumornecrosis factor-alpha,TNF-α)的表达以及N-乙酰半胱氨酸(N-acetylcysteine,NAC)的干预影响,探讨一种预防小鼠感染性早产发生的新策略。方法:利用逆转录-聚合酶链反应(RT-PCR)和免疫组化方法检测早产小鼠胎盘TLR4、NF-κBp65、TNF-αmRNA和蛋白的表达,以及NAC干预后早产率、TLR4、NF-κBp65和TNF-α的表达变化。结果:对照组都有TLR4、NF-κBp65、TNF-α的少量表达,LPS模型组和对照组相比三者表达都显著升高(P<0.05);NAC+LPS和模型组相比,TLR4表达无明显变化,而NF-κBp65和TNF-α表达明显减少(P<0.05),并且早产率也明显下降(P<0.05);LPS+NAC治疗组和模型组相比无统计学意义。结论:NAC可以降低感染性早产小鼠胎盘NF-κBp65和TNF-α的表达,在早产的预防中有一定作用。
