摘要 目的:探讨正常和妊娠期肝内胆汁淤积症胎盘组织中COX-2表达的意义。方法:采用组织微阵列技术和免疫组织化学染色方法检测正常胎盘(30例)和ICP胎盘(轻度28例,重度19例)组织中COX-2蛋白的表达水平。结果:COX-2在正常胎盘和ICP胎盘绒毛表面合体滋养细胞胞浆内呈阳性表达,绒毛间质细胞、血管平滑肌细胞和内皮细胞胞浆着色也较明显;ICP重度组单位胎盘面积IOD最高(63.4±5.5),ICP轻度组次之(56.5±2.9),正常胎盘最低(49.2±7.8),3组间差异显著(P<0.01)。结论:ICP胎盘中COX-2增加可能是ICP易于发生早产的病理生理基础,增高的COX-2通过上调PG的合成与释放而诱发子宫收缩。
