Circulating microRNAs (miRNAs) have been increasingly suggested as biomarkers for numerous diseases. The aims of this study were to evaluate the expression of plasma miR-27a/b in patients with acute pulmonary embolism (APE) and determine the possibility of miR-27a/b as diagnostic biomarkers for APE.
Seventy-eight APE patients diagnosed by computed tomographic pulmonary angiography (CTPA) and 70 age and gender matched normal volunteers were included in this study. The levels of miR-27a and miR-27b were measured by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and the concentrations of plasma D-dimer were measured using immunoturbidimetric assay.
The levels of plasma miR-27a and miR-27b were significantly higher in APE patients (P<0.001) compared with normal controls. Receiver operating characteristic (ROC) curve analyses showed that plasma miR-27a was superior to miR-27b for the diagnosis of APE (AUC=0.784, AUC=0.707, respectively). Combining miR-27a or miR-27b with D-dimer significantly increased the diagnostic capacity of APE.
Our results showed that circulating miR-27a and miR-27b might be potential novel diagnostic biomarkers in APE patients.
循环微小RNA(miRNA)越来越多地被认为是多种疾病的生物标志物。本研究旨在评估急性肺栓塞(APE)患者血浆miR-27a/b的表达,并确定miR-27a/b作为APE诊断生物标志物的可能性。
本研究纳入了78例经计算机断层扫描肺动脉造影(CTPA)诊断的APE患者和70例年龄及性别匹配的正常志愿者。采用定量逆转录-聚合酶链反应(qRT-PCR)检测miR-27a和miR-27b的水平,采用免疫比浊法检测血浆D-二聚体的浓度。
与正常对照组相比,APE患者血浆miR-27a和miR-27b水平显著升高(P<0.001)。受试者工作特征(ROC)曲线分析表明,血浆miR-27a在诊断APE方面优于miR-27b(AUC分别为0.784和0.707)。将miR-27a或miR-27b与D-二聚体联合使用可显著提高APE的诊断能力。
我们的结果表明,循环miR-27a和miR-27b可能是APE患者潜在的新型诊断生物标志物。
