  • 简介:【 摘要】 目的 : 探讨白介素 - 6( IL- 6 ) , 白介素 - 8( IL- 8 ) 与胎膜早破 的关系 。 方法 : 收集 2018年 1月 -2019年 1月的 160例胎膜早破孕妇作为病例组 ; 随机抽取同期正常孕妇160例作为对照组 。 两组孕妇入院后即抽取静脉血提 取血清 ,采用 ELISA 法检测血清中IL- 6 、IL- 8的含量 ,统计分析病例组和对照组感染绒毛膜羊膜炎的几率 ,采用 western blot 测定胎盘组织中 IL- 6 、IL- 8含量 。结果 : 病例组血清中 IL- 6 ,IL- 8 的含量明显高于对照组 , 差异有统计学意义 ;病例组感染绒毛膜羊膜炎的几率明显高于对照组 , 差异有统计学意义 ; 结论 :IL- 6 ,IL- 8 可能全程参与妊娠过程 ,因此联合监测 IL- 6 、IL- 8 的含量对于预测胎膜早破新生儿的预后有一定的作用 , 尤其在降低新生儿死亡率 、预防远期并发症等方面有一定价值 。
