母胎界面MCP-1表达异常与不明原因早期复发性流产的关系

目的:探讨绒毛、蜕膜组织中单核细胞趋化蛋白-1(MCP-1)表达异常与不明原因早期复发性流产(UERSA)的关系。方法:选取UERSA患者30例(UERSA组)以及同孕龄正常早孕妇女30例(正常早孕组),应用实时荧光定量聚合酶链反应(RT-PCR)技术检测两组绒毛、蜕膜组织中MCP-1mRNA的表达水平,应用酶联免疫吸附测定(ELISA)方法检测两组血清中MCP-1蛋白的含量。结果:早孕绒毛、蜕膜组织均有MCP-1mRNA的表达;UERSA组绒毛、蜕膜组织中MCP-1mRNA的表达量(1.96±0.39,3.67±0.98)均较正常早孕组(1.42±0.28,1.90±0.85)显著升高(P<0.01);UERSA组血清MCP-1蛋白含量为85.74±12.31pg/ml,较正常早孕组(59.41±9.70pg/ml)显著升高(P<0.01);血清MCP-1蛋白的含量与绒毛、蜕膜组织中MCP-1mRNA的水平分别呈正相关(r=0.595,0.655)。结论MCP-1表达于早孕母胎界面,绒毛、蜕膜组织MCP-1mRNA高表达可能与UERSA的发病机制有关,提示血清MCP-1升高在胚胎停育的早期诊断中具有重要的临床意义。

Abnormal expression of monocyte chemotactic protein-1 in pathogenesis of unexplained early recurrent spontaneous abortion

Objective: To investigate the relationship between abnormal expressions of monocyte chemotactic protein-1 (MCP-1) mRNA in villus and decidua and unexplained early recurrent spontaneous abortion (UERSA). Methods: The expressions of MCP-1 mRNA in villus and decidua tissues of 30 UERSA patients (UERSA group) and 30 normal early pregnancy women (normal early pregnancy group) were determined by real-time fluorescence quantitative PCR. The maternal serum levels of MCP-1 were detected by ELISA. Results: The MCP-1 ...
