Abstract

目的测定不同缺铁程度足月孕妇血清铁调素的浓度及胎盘中膜铁转运蛋白1(FPN1) mRNA的表达水平,探讨其在母婴铁转运中的作用及调控机制。方法以55例足月孕妇为研究对象,检测母婴HGB、血清铁(SI)及血清铁蛋白(SF)水平。采用RT-PCR方法检测胎盘组织FPN1 mRNA的表达水平,应用双抗夹心生物素-亲和素-酶联免疫吸附试验检测血清铁调素浓度。比较不同铁状态孕妇FPN1 mRNA及铁调素浓度的差异。结果不同缺铁程度组孕妇相应新生儿脐血HGB、SI、SF水平比较差异均无统计学意义(P值均>0.05)。正常组、铁缺乏组及缺铁性贫血(IDA)组孕妇血清铁调素浓度分别为(193.637±52.219)、(176.523±43.875)及(147.623±37.768)µg/L,差异有统计学意义(F=3.872,P=0.027);胎盘FPN1 mRNA的表达水平分别为0.462±0.077、0.507±0.074及0.551±0.104,差异有统计学意义(F=4.767,P=0.013)。孕妇血清铁调素水平与胎盘FPN1 mRNA表达水平呈负相关(r=−0.383, P=0.004)。结论不同缺铁程度孕妇相应新生儿铁状态无明显差异,随着母体缺铁程度的加重,血清铁调素浓度下调,胎盘FPN1 mRNA表达上调。
