Abstract： 目的探讨妊娠期妇女血清和胎盘组织中卵泡休止素(FS)水平变化及意义.方法采用FS特异双抗体夹心酶联免疫吸附试验,检测早期妊娠、足月妊娠妇女和生理月经期妇女的血清FS水平;采用逆转录聚合酶链反应(RT-PCR)法、半定量检测FS mRNA在足月妊娠妇女胎盘及卵巢组织中的表达.结果 (1)足月妊娠妇女血清FS水平为(180±26)μg/L,明显高于早期妊娠妇女的(4.4±2.1)μg/L, 两者比较,差异有极显著性(P<0.001);也明显高于生理月经期妇女的(1.5±2.2)μg/L,两者比较,差异有极显著性(P<0.001).(2)足月妊娠妇女胎盘组织FS mRNA呈强阳性表达,生理月经期妇女的卵巢组织FS mRNA呈阳性表达,足月妊娠妇女的卵巢组织FS mRNA呈弱阳性表达.(3)RT-PCR检测显示,足月妊娠妇女的胎盘组织FS mRNA的表达水平(0.8±0.4)高于其卵巢组织(0.4±0.3),两者比较,差异也有显著性(P<0.05);但低于生理月经期妇女的卵巢组织(0.93±0.13),两者比较,差异有显著性( P<0.05).结论 (1)妇女生理月经期卵巢组织可分泌FS,并有少量的FS mRNA表达.但在妊娠期卵巢分泌FS的功能受到抑制.(2)足月妊娠妇女的血清FS主要来源于胎儿-胎盘单位.FS在妊娠过程中对胚胎发育及胎盘功能可能有重要的调节作用.
