摘要:

目的 探讨外周血微小 RNA(microRNA,miRNA)⁃92a miR⁃342 在急性肺损伤(acute lung injury,ALI)患者诊断和预后的临床价值。方法 选取 60 ALI 患者,根据随访生存状态将患者分为 ALI 存活组(n = 40)和ALI死亡组(n = 20),并选取同期体检的52例健康者作为对照组,采用RT⁃PCR分析外周血 miR⁃92a miR⁃342 表达水平,收集患者临床资料,Cox 回归分析 ALI 患者死亡危险因素,绘制受试者工作 特征曲线(receiver operating characteristic,ROC)评价miR⁃92a和miR⁃342对ALI患者诊断价值。结果 与对 照组相比,ALI 存活组和 ALI 死亡组 APACHEⅡ评分、LIPS 评分更高,外周血中 CRP 更高。qRT⁃PCR 分析结果表明,ALI 存活组 miR⁃92a 相对表达水平高于对照组(P < 0.05),ALI 死亡组 miR⁃92a 相对表达水平高于 ALI 存活组(P < 0.05);ALI 存活组 miR⁃342 相对表达水平低于对照组(P < 0.05),ALI 死亡组 miR⁃342 相对 表达水平显著低于 ALI 存活组(P < 0.05)。Cox 回归分析结果表明,外周血 CRP、miR⁃92a miR⁃342 平是影响 ALI 发生风险的独立危险因素(P < 0.05)。ROC 结果表明,miR⁃92a 曲线下面积为 0.865,灵敏 度为 84.39%,特异度为 73.29%,截断值为 2.16;miR⁃342 曲线下面积为 0.839,灵敏度为 82.19%,特异度 71.77%,截断值为 0.56。MiR⁃92a miR⁃342 联合诊断曲线下面积为 0.895,灵敏度为 86.87%,特异度 76.57%。结论 外周血 miR⁃92a miR⁃342 水平与 ALI 有关,二者联合检测可为 ALI 早期预测提供 临床依据。

Abstract:

Objective To investigate the clinical value of peripheral blood microRNA(miRNA)⁃92a and miR ⁃342 in the diagnosis and prognosis of patients with acute lung injury(ALI). Method Sixty patients with ALI were divided into ALI survival group(n = 40)and ALI death group(n = 20)according to their survival status during follow⁃up,and 52 healthy subjects were selected as control group. The expression levels of miR⁃92a and miR⁃ 342 in the peripheral blood were analyzed by RT⁃PCR,and the clinical data of the patients were collected. Cox regression was used to analyze the risk factors of death in the ALI patients,and receiver operating characteristic (ROC)curves were plotted to evaluate the diagnostic value of miR ⁃ 92a and miR ⁃ 342 in ALI patients. Results Compared with the control group,the APACHEII score and LIPS score were higher and CRP in the peripheral blood was higher in the ALI survival group and ALI death group. The results of qRT⁃PCR analysis showed that the relative expression level of miR ⁃92a in the ALI survival group was higher than in the control group(P < 0.05), and higher in the ALI death group than in the ALI survival group(P < 0.05. The relative expression level of miR⁃ 342 in the ALI survival group was lower than in the control group(P < 0.05),and the relative expression level of miR⁃342 in the ALI death group was significantly lower than in the ALI survival group(P < 0.05). The results of Cox regression analysis showed that peripheral blood CRP,miR ⁃92a and miR ⁃342 levels were independent risk factors affecting the risk of ALI(P < 0.05). ROC results showed that miR⁃92a had an area under the curve of 0.865 a sensitivity of 84.39%,a specificity of 73.29%,and a cutoff value of 2.16;miR⁃342 had an area under the curve of 0.839,a sensitivity of 82.19%,a specificity of 71.77%,and a cutoff value of 0.56. The MiR⁃92a and miR⁃342 combined diagnostic area under the curve was 0.895,with a sensitivity of 86.87%,and a specificity of 76.57%.Conclusion The levels of miR⁃92a and miR⁃342 in peripheral blood are related to acute lung injury,and the com⁃ bined detection of miR⁃92a and miR⁃342 can provide clinical evidence for the early prediction of acute lung injury.
