文摘目的:观察妊娠期糖尿病(gestational diabetes mellitus,GDM)孕妇胎盘滋养细胞超微结构,探讨铁死亡在GDM发生发展中的作用。方法:选取2020年9月—2022年12月在常州妇幼保健院分娩的孕妇,孕24~28周行口服葡萄糖耐量试验。以确诊GDM的孕产妇为研究对象,分为通过饮食治疗控制血糖满意组(G1组)、口服二甲双胍控制血糖组(G2组)、胰岛素控制血糖组(G3组)、血糖控制不满意但拒用药组(G4组)各30例,正常健康孕妇为对照组(N组)。通过透射电镜观察各组胎盘滋养细胞超微结构;普鲁士蓝染色检查胎盘铁沉积情况;免疫组化检测胎盘长链脂酰辅酶A合成酶4(acyl-CoA synthetase long chain family member 4,ACSL4)、谷胱甘肽过氧化物酶4(glutathione peroxidase 4,GPX4)在合体滋养细胞层的定位和表达;Western blot和q RT-PCR分别检测胎盘ACSL4、GPX4蛋白和mRNA转录水平。结果:透射电镜下G1、G2、G3、G4组GDM产妇胎盘均可见不同程度的线粒体形态学改变,其中G1、G2、G3组线粒体改变较轻,G4组见典型的铁死亡萎缩线粒体。普鲁士蓝染色显示5组胎盘均见含铁颗粒,G1、G2、G3、G4组胎盘中含铁颗粒较N组明显增多,G1、G2、G3组胎盘中的含铁颗粒较G4组明显减少。Western blot结果显示,与N组相比,G1、G2、G3、G4组产妇胎盘中ACSL4蛋白表达增加而GPX4蛋白表达下降,qRT-PCR结果显示各组间ACSL4、GPX4的mRNA转录水平无显著性差异。结论:GDM孕妇胎盘滋养细胞中存在铁死亡,且与病情严重程度和用药相关。GDM孕妇胎盘中ACSL4、GPX4表达异常,二甲双胍和胰岛素有改善胎盘滋养细胞铁死亡的作用。
