摘要: 目的 探究 miR-144 在慢性阻塞性肺疾病 ( chronic obstructive pulmonary disease, COPD) 患者外 周血血清和单核细胞中的表达及其临床意义。 方法 选取 2020 年 3 月至 2021 年 6 月内江市第二人民医院 收治的 58 例 COPD 稳定期患者为观察组, 另选取同期 45 例健康体检者为对照组。 收集所有患者的一般临 床资料。 采用实时荧光定量 PCR 法 (qRT-PCR) 检测所有患者外周血血清和单核细胞中 miR-144 的表达水 平。 分析 COPD 患者外周血血清及单核细胞中 miR-144 表达水平与肺功能的关系。 Pearson 相关性分析 COPD 患者外周血血清及单核细胞 miR-144 表达水平与一秒用力呼气容积 ( forced expiratory volume in first second, FEV1) 的相关关系。 ROC 曲线分析患者外周血血清和单核细胞 miR-144 水平对 COPD 的诊断价值。 结果 与对照组相比, COPD 患者外周血血清及单核细胞中 miR-144 的表达水平均明显升高, 其差异具有 统计学意义 (P< 0. 05)。 COPD 患者外周血血清及单核细胞中 miR-144 的表达水平均随着肺功能严重程度 的加重而依次升高, 其差异具有统计学意义 (P< 0. 05)。 Pearson 相关性分析结果显示, COPD 患者外周血 血清及单核细胞 miR-144 表达水平与 FEV1 均呈负相关关系 (r = - 0. 517, r = - 0. 463, P< 0. 05)。 ROC 曲 线分析结果显示, 外周血血清和单核细胞 miR-144 水平对 COPD 诊断价值的 ROC 曲线下面积 (AUC) 分别 为 0. 857、 0. 849, 截断值为 1. 371、 1. 890, 敏感度为 84. 50 % 、 84. 50 % , 特异性为 80. 00 % 、 88. 90 % 。 结论 COPD 患者外周血血清和单核细胞 miR-144 水平显著上调, 且参与调节疾病的发展程度, 对发生 COPD 具有一定的诊断价值。

Abstract: Objective To explore the expression of miR-144 in the peripheral blood serum and monocytes from patients with chronic obstructive pulmonary disease (COPD) and its clinical significance. Methods Fifty-eight COPD patients at the stable period admitted to our hospital from March 2020 to June 2021 were selected as the observation group, and 45 healthy patients during the same period were selected as the control group. The general clinical data of all patients were collected. Real-time fluorescent quantitative PCR ( qRT-PCR) was used to detect the expression level of miR-144 in the peripheral blood serum and monocytes of all patients. The relationship between the expression level of miR-144 in the peripheral blood serum and monocytes and the lung function in patients with COPD was analyzed. Pearson correlation was used to analyze the correlation between the expression level of miR-144 in the peripheral blood serum and monocytes of COPD patients and the forced expiratory volume in first second (FEV1). ROC curve was used to analyze the diagnostic value of miR-144 expression levels in the peripheral blood serum and monocyte for COPD. Results The expression level of miR-144 in the peripheral blood serum and monocytes of COPD patients was significantly higher compared with the control group, (P < 0. 05). The expression level of miR-144 in the peripheral blood serum and monocytes of COPD patients increased with the aggravation of lung function, and the difference was statistically significant (P< 0. 05). The results of Pearson correlation analysis showed that the expression level of miR-144 in the peripheral blood serum and monocytes of COPD patients was negatively correlated with FEV1 ( r = - 0. 517, r = - 0. 463, P< 0. 05). ROC curve analysis results showed that the areas under the ROC curve (AUCs) of miR-144 levels in the peripheral blood serum and monocyte for the diagnosis of COPD were 0. 857 and 0. 849, with the cut-off values to be 1. 371 and 1. 890, the sensitivities to be 84. 50 % and 84. 50 % , and the specificities to be 80. 00 % and 88. 90 % , respectively. Conclusion The expression level of miR-144 in the peripheral blood serum and monocyte of patients with COPD is significantly up-regulated, they participate in the regulation of the development of the disease, and have a certain diagnostic value for the occurrence of COPD.
