摘要目的评估microRNA-520a作为异位妊娠(ectopic pregnancy,EP)患者非侵入性血清学诊断标志物的临床应用价值。方法收集2017年1月至2018年12月首都医科大学附属北京妇产医院185例孕妇的病例资料及其首次就诊送检的血液标本,包括64例宫腔妊娠(viable intrauterine pregnancy,VIP)、48例自然流产(spontaneous abortion,SA)以及73例EP,采用定量反转录聚合酶链反应(reverse transcription polymerase chain reaction,RT-PCR)检测患者血浆中microRNA-520a的表达水平。同时检测血清绒毛膜促性腺激素(human chorionic gonadotrophin,HCG)和孕酮水平,并比较各组间差异。采用ROC曲线分析microRNA-520a浓度作为EP血清学诊断标志物的有效性。结果microRNA-520a在EP组血浆中的表达水平(1.88±0.50)与VIP组(2.67±0.61,P=0.000)及SA组(2.77±0.50,P<0.001)比较,均显著下降。用于VIP与EP的鉴别诊断,ROC曲线的AUC为0.82(95%CI:0.68~0.97,P=0.001)。结论异位妊娠者血浆标本中microRNA-520a表达水平显著下降,microRNA-520a可作为血清学标志物应用于早期EP诊断。
