摘要 目的探讨脓毒症患儿循环外泌体中长链非编码RNA HOXA11-AS(LncRNA HOXA11-AS)的表达水平及对脓毒症的筛查效能。方法选取2018年10月至2019年10月就诊的脓毒症患儿80例作为脓毒症组,另选取同期性别和年龄相匹配的体检健康儿童60例作为对照组。采集2组外周静脉血标本并提取外泌体。实时荧光定量聚合酶链反应(RT-PCR)检测2组外泌体中LncRNA HOXA11-AS的表达水平。ROC曲线分析LncRNA HOXA11-AS对脓毒症患儿的筛查效能。结果脓毒症患儿外周循环外泌体中LncRNA HOXA11-AS的表达水平明显高于对照组(1.54±0.89 vs 0.53±0.17,t=15.23,P<0.001)。LncRNA HOXA11-AS的表达与SOFA评分呈正相关(r=0.589,P<0.001)。脓毒症患儿C反应蛋白(CRP)浓度与SOFA评分呈正相关(r=0.432,P<0.01)。LncRNA HOXA11-AS的表达与WBC及CRP浓度呈正相关(r分别为0.561、0.614,P均<0.001)。外周循环外泌体中LncRNA HOXA11-AS筛查脓毒症的ROC曲线下面积(AUCROC)为0.947,当cut-off值为1.23时,敏感性为90.9%,特异性为93.9%。结论外周循环外泌体中LncRNA HOXA11-AS对儿童脓毒症的诊断具有较高的筛查价值。
