摘要(Abstract)：

目的:检测出生体重异常儿胎盘及母体血清中microRNA517a(miR-517a)、microRNA518b(miR-518b)、microRNA519a(miR-519a)的表达,探讨这三种微RNAs(miR-NAs)对出生体重的影响。方法:选择无妊娠并发症和合并症的足月分娩产妇,按胎儿出生体重分为:正常出生体重儿组(对照组,15例)、巨大儿组(20例)及小样儿组(15例)。分别收集3组的新鲜胎盘组织及母体血清,用实时荧光定量PCR方法检测3组miRNAs的变化。结果:miR-517a在巨大儿组(3.28±1.04)与小样儿组(3.63±1.45)胎盘中的表达均显著高于对照组(0.29±0.91)(P均<0.05);miR-519a在巨大儿组(4.62±0.44)与小样儿组(5.99±1.06)胎盘中的表达亦均显著高于对照组(2.65±0.57)(P均<0.05);而miR-518b在3组胎盘中的表达无统计学差异(P>0.05)。miR-517a在巨大儿组(2.76±0.44)与小样儿组(3.69±0.79)母体血清中的表达均显著高于对照组(0.14±1.81)(P均<0.05);miR-519a在巨大儿组(1.93±0.76)与小样儿组(0.47±1.17)母体血清中的表达均显著低于对照组(4.56±0.74)(P均<0.05);而miR-518b在三组母体血清中的表达无统计学差异(P>0.05)。结论:miR-517a、miR-519a参与了异常出生体重的调节。
