摘要 目的探讨外周血中miR-27a和GATA结合蛋白6(GATA6)的表达水平与妊娠合并心脏病孕妇妊娠结局关系。方法回顾性分析2017年5月至2019年7月西安医学院第二附属医院妇产科收治的不良妊娠结局妊娠合并心脏病孕妇81例作为病例组,另取同期就诊的妊娠合并心脏病妊娠结局良好者81例为对照组,收集孕妇治疗前血清,实时定量PCR(RT-qPCR)检测孕妇血清miR-27a的表达水平;western blot检测GATA6蛋白的表达水平;ELISA法检测血清心肌肌钙蛋白I(cTnI)的表达水平;放射免疫法检测血清pro-BNP的表达水平;采用Pearson法分析血清miR-27a、GATA6蛋白与血清cTnI、pro-BNP水平的相关性;采用Logistic回归模型分析影响妊娠合并心脏病孕妇不良妊娠结局的危险因素。ROC曲线分析miR-27a、GATA6、cTnI、pro-BNP对妊娠合并心脏病的诊断价值。结果与对照组比较,病例组心功能分级Ⅰ+Ⅱ级比例、GATA6 mRNA水平均显著降低,而Ⅲ+Ⅳ级比例、血清miR-27a、cTnI、pro-BNP水平均显著增加(P均<0.05)。此外,与心功能分级Ⅰ+Ⅱ级比较,Ⅲ+Ⅳ级患者血清miR-27a、cTnI、pro-BNP表达水平均显著升高,GATA6 mRNA水平显著降低(P均<0.001);妊娠合并心脏病孕妇血清miR-27a与GATA6 mRNA水平呈负相关(r=-0.499,P<0.05),而与血清cTnI、pro-BNP水平均呈正相关(r分别为0.512、0.497,P<0.05),此外,GATA6 mRNA与cTnI、pro-BNP水平均呈负相关(r分别为-0.531、-0.524,P<0.05)。Logistic回归分析结果发现,心功能分级升高、血清miR-27a、cTnI、pro-BNP水平升高、GATA6水平降低是影响妊娠合并心脏病孕妇不良妊娠结局的危险因素(P<0.05)。结论血清miR-27a水平增加及GATA6蛋白水平降低可能与妊娠合并心脏病孕妇心肌损伤有关,是影响不良妊娠结局的危险因素。
