摘要 目的:测定母血、脐血及羊水中胰岛素样生长因子-1(IGF-1)的水平,探讨胰岛素样生长因子-1与妊娠晚期糖尿病患者的肾功能、视网膜病变分级以及新生儿结局的相关性。方法:采用酶联免疫吸附法(ELISA)检测妊娠糖尿病孕妇(妊娠期糖尿病组26例、妊娠合并糖尿病组20例)以及正常妊娠孕妇的血清、脐血及羊水中IGF-1的水平;测定孕妇肾功能指标;查看眼底,了解视网膜病变的程度;记录新生儿体重、胎盘重量、身高;分析母血IGF-1与新生儿指标、视网膜病变的分级、肾功能状态的相关性。结果:①母血、脐血和羊水中均有不同水平的IGF-1存在,以母血水平最高。②GDM组母血、脐血和羊水中IGF-1水平均较正常妊娠组高,有显著性差异(P<0.05),DM组较正常孕妇组高,有极显著性差异(P<0.01)。③在GDM组和妊娠合并DM组新生儿身长与对照组均无显著性差异,GDM组和妊娠合并DM组新生儿体重、胎盘重量与对照组比较均有显著性差异(P均<0.05)。④对照组眼底检查均正常,而GDM组中有7例、妊娠合并DM组中12例眼底检查为异常。⑤GDM组和妊娠合并DM组中母血IGF-1水平均与脐血、羊水中的IGF-1水平呈正相关;GDM组和妊娠合并DM组中母血IGF-1水平与新生儿体重、胎盘重量均呈正相关;GDM组和妊娠合并DM组母血中IGF-1水平与视网膜病变无相关性;妊娠合并DM组母血中IGF-1水平与空腹血糖呈正相关。结论:胎儿循环中的IGF-1是胎儿生长发育的主要调节因子,并参与了GDM或妊娠合并DM的病理生理过程。
