摘要 目的:分析重症肺炎患者支气管肺泡灌洗液微小RNA–127–5p的表达特征。方法:选取清远市人民医院2016年6月至2018年2月期间收治的50例接受支气管肺泡灌洗的肺炎患者,根据是否为重症肺炎将50例肺炎患者分为观察组(重症肺炎)和对照组(非重症肺炎),收集两组患者支气管肺泡灌洗液,应用实时荧光定量多聚核苷酸链式反应(q PCR)法检测灌洗液中微小RNA–127–5p的表达量,绘制ROC曲线,评价支气管肺泡灌洗液微小RNA–127–5p表达变化在重症肺炎临床诊断中的应用价值。结果:观察组患者支气管肺泡灌洗液中微小RNA–127–5p的表达水平明显低于对照组患者,组间比较,差异具有统计学意义(P<0.05),微小RNA–127–5p表达变化诊断重症肺炎的ROC曲线下面积为0.862,95%CI为0.811~0.960,标准误为0.059,P值为0.002。当以0.845为临界值时,诊断重症肺炎的敏感性为87.2%,特异性为71.6%。结论:重症肺炎患者支气管肺泡灌洗液中微小RNA–127–5p的表达会随着病情的不断恶化呈下降趋势,用于辅助诊断重症肺炎具有较高的敏感性和特异性。
