Predictive value and efficacy evaluation of plasma miR-132,miR-134 combined with miR-124 in patients with depression

目的探讨血浆微小核糖核酸(miR)-132、miR-134联合miR-124对抑郁症患者的预测价值及疗效评估。方法选取2021年6月至2023年7月在该院精神病科确诊抑郁症患者75例作为研究组,另选取同期于该院体检的健康者75例作为对照组。检测两组血浆miR-132、miR-134及miR-124相对表达水平,并对两组治疗8周前后miR-132、miR-124、miR-134、脑源性神经营养因子(BDNF)、炎症因子[白细胞介素(IL)-6、IL-18、肿瘤坏死因子-α(TNF-α)]水平进行比较。采用多元线性回归分析构建联合预测模型。采用受试者工作特征(ROC)曲线评估血浆miR-132、miR-134、miR-124及联合预测在诊断抑郁症患者中的应用价值。结果研究组血浆miR-132、miR-124相对表达水平显著高于对照组,差异有统计学意义(P<0.05);研究组血浆miR-134相对表达水平显著低于对照组,差异有统计学意义(P<0.05)。ROC曲线分析显示,血浆miR-132、miR-134、miR-124及联合预测诊断抑郁症的曲线下面积分别为0.8588、0.8519、0.7631、0.9714。与治疗8周前比较,治疗8周后血浆miR-132、miR-124、IL-6、IL-18、TNF-α水平明显下调,miR-134、BDNF水平明显上调。结论miR-132、miR-134及miR-124与抑郁症的发生密切相关,三者联合可用于预测、早期诊断抑郁症患者及评估抑郁症患者的药物疗效。

Objective To explore the predictive value and efficacy evaluation of plasma microRNA(miR)-132,miR-134 combined with miR-124 in patients with depression.Methods A total of 75 patients diagnosed with depression in the psychiatric department of the hospital from June 2021 to July 2023 were selected as the study group,and 75 healthy subjects who underwent physical examination in the hospital during the same period were selected as the control group.The relative expression levels of miR-132,miR-134 and miR-124 in plasma of the two groups were detected.The levels of miR-132,miR-124,miR-134,brain-derived neurotrophic factor(BDNF),inflammatory factors[interleukin(IL)-6,IL-18,tumor necrosis factor-α(TNF-α)]were compared between the two groups before and after 8 weeks of treatment.Multiple linear regression analysis was used to construct a joint prediction model.The application value of plasma miR-132,miR-134,miR-124 and combined prediction in the diagnosis of depression was evaluated by receiver operating characteristic(ROC)curve.Results The relative expression levels of miR-132 and miR-124 in plasma of the study group were significantly higher than those of the control group,with statistical significance(P<0.05).The relative expression level of miR-134 in the study group was significantly lower than that in the control group,and the difference was statistically significant(P<0.05).ROC curve analysis showed that the area under the curve of plasma miR-132,miR-134,miR-124 and combined prediction of depression were 0.8588,0.8519,0.7631 and 0.9714,respectively.Compared with 8 weeks before treatment,plasma miR-132,miR-124,IL-6,IL-18 and TNF-αlevels were significantly down-regulated,while plasma miR-134 and BDNF levels were significantly upregulated after 8 weeks of treatment.Conclusion miR-132,miR-134 and miR-124 are closely related to the oc-currence of depression,and the combination of the three can be used to predict and early diagnose depression patients and evaluate the drug efficacy of depression patients.
