摘要:

目的 探讨慢性阻塞性肺疾病(COPD)患者血清miR-455-3p、miR-106b-5p表达的变化及其临床意义。方法 选取2022年3月—2024年3月青海红十字医院COPD患者109例(COPD组)、健康体检者90名(正常对照组)。根据病情将COPD患者分为稳定期组(47例)和慢性阻塞性肺疾病急性加重期(AECOPD)组(62例)。收集所有研究对象的临床资料,检测血清miR-455-3p、miR-106b-5相对表达量和肺功能指标[第1秒用力呼气量(FEV1)、用力肺活量(FVC)、最大呼气峰流速(PEF)],计算FEV1/FVC比值。采用Pearson相关分析评估患者血清miR-455-3p、miR-106b-5p与肺功能指标的相关性。采用Logistic回归分析评估AECOPD发生的影响因素。采用受试者工作特征(ROC)曲线评价血清miR-455-3p、miR-106b-5p诊断AECOPD的效能。结果 COPD组血清miR-455-3p、miR-106b-5p相对表达量均低于正常对照组(P<0.001)。与稳定期组比较,AECOPD组血清miR-455-3p、miR-106b-5p相对表达量和FEV1、FVC、FEV1/FVC比值、PEF均降低(P<0.01)。COPD患者血清miR-455-3p、miR-106b-5p表达与肺功能指标(FEV1、FVC、FEV1/FVC比值、PEF)均呈正相关(P<0.001)。血清miR-455-3p、miR-106b-5p表达和FEV1、FVC、FEV1/FVC比值、PEF水平降低均是AECOPD发生的危险因素(P<0.05)。miR-455-3p、miR-106b-5p单项检测和联合检测诊断AECOPD的曲线下面积(AUC)分别为0.733、0.842、0.894。结论 COPD患者血清miR-455-3p、miR-106b-5p均呈低表达,与肺功能指标密切相关,二者联合检测对AECOPD有较高的辅助诊断价值。

Abstract:

Objective To investigate the changes in serum miR-455-3p and miR-106b-5p expressions in patients with chronic obstructive pulmonary disease(COPD)and their clinical significance. Methods A total of 109 COPD patients(COPD group)and 90 healthy subjects(healthy control group)were enrolled from Qinghai Red Cross Hospital from March 2022 to March 2024. Based on disease severity,COPD patients were classified into stable phase group(47 cases)and acute exacerbation of chronic obstructive pulmonary disease(AECOPD)group(62 cases). The clinical data were collected,and serum levels of miR-455-3p and miR-106b-5p were determined along with lung function parameters including forced expiratory volume in one second(FEV1),forced vital capacity(FVC),peak expiratory flow(PEF)and FEV1/FVC ratio. Pearson correlation analysis was used to assess the relationship between serum miR-455-3p and miR-106b-5p levels and lung function indicators. Logistic regression analysis was performed to identify risk factors for AECOPD. Receiver operating characteristic(ROC)curves were used to evaluate the diagnostic performance of serum miR-455-3p and miR-106b-5p for AECOPD. Results The relative expression levels of serum miR-455-3p and miR-106b-5p were lower in COPD group compared to healthy control group(P<0.001). Compared with stable phase group,the AECOPD group showed reduced relative expression of miR-455-3p and miR-106b-5p,as well as lower FEV1,FVC,FEV1/FVC ratio and PEF(P<0.01). Serum expressions of miR-455-3p and miR-106b-5p in COPD patients were positively correlated with lung function parameters(FEV1,FVC,FEV1/FVC,PEF)(P<0.001). Reduced expressions of miR-455-3p and miR-106b-5p,as well as decreased FEV1,FVC,FEV1/FVC and PEF levels,were all independent risk factors for AECOPD(P<0.05). The areas under curves(AUC) of miR-455-3p,miR-106b-5p single and combined determinations were 0.733,0.842 and 0.894,respectively. Conclusions Serum miR-455-3p and miR-106b-5p are downregulated in COPD patients and correlated with lung function parameters. The combined determination has high diagnostic value for AECOPD.
