摘要 目的观察子痫前期(PE)患者胎盘及脐带组织吲哚胺2,3-双加氧酶(IDO)、巨噬细胞移动抑制因子(MIF)的表达变化,并探讨其意义。方法 PE患者66例,其中轻度32例(轻度组)、重度34例(重度组),同期健康晚孕妇女42例作为对照组。分别采用RT-PCR法和Western blot法检测胎盘、脐带组织中IDO、MIF mRNA和蛋白,用彩色超声多普勒诊断仪检测各组产前胎儿的脐动脉血流阻力指数(RI),记录新生儿体质量。结果重度组、轻度组、对照组胎盘、脐带组织IDO mRNA及蛋白相对表达均逐渐升高,MIF mRNA及蛋白相对表达、RI均逐渐降低;组间两两比较,P均<0.01。重度组新生儿体质量均低于轻度组和对照组,P均<0.01。PE患者中,胎盘、脐带组织IDO、MIF mRNA相对表达均呈负相关(r分别为-0.468、-0.455),P均<0.01;胎盘、脐带组织IDO mRNA表达水平与RI均呈负相关(r分别为-0.317、-0.526),与新生儿体质量均呈正相关(r分别为0.398、0.461),P均<0.01;胎盘、脐带组织MIF mRNA表达水平与RI均呈正相关(r分别为0.393、0.502),与新生儿体质量均呈负相关(r分别为-0.302、-0.431),P均<0.01。结论 PE患者胎盘及脐带组织中IDO表达降低、MIF表达升高,与胎儿RI升高和新生儿体质量降低有关,可能参与PE的发病。
