摘要:

目的 通过检测肝纤维化患者外周血中miR-571的表达,探讨miR-571水平对肝纤维化的诊断意义。 方法 选取2022年12月至2023年9月诊断为肝纤维化的患者40例(肝纤维化组)、肝炎患者40例(肝炎组)和健康对照者40例(健康对照组)作为研究对象。采用实时荧光定量PCR检测外周血中miR-571的表达水平,分析各组中miR-571的相对表达量。使用Spearman相关性分析miR-571与临床常见指标的相关性。通过二元logistic回归构建多变量诊断模型,并绘制ROC曲线评价miR-571和多变量诊断模型对肝纤维化的诊断能力。 结果 肝纤维化组中miR-571的表达水平显著高于健康对照组和肝炎组,差异有统计学意义(P < 0.001)。Spearman相关性分析显示,miR-571的表达水平与ALT、APRI评分和FIB-4指数呈正相关(r = 0.23、0.30、0.22,P < 0.05),与PLT呈负相关(r = -0.19,P < 0.05)。logistic回归分析得出miR-571和FIB-4指数是肝纤维化的独立危险因素。ROC曲线结果显示miR-571诊断纤维化的AUC为0.91(95%CI:0.85 ~ 0.96),miR-571联合FIB-4指数诊断肝纤维化的AUC为0.94(95%CI:0.90 ~ 0.98)。 结论 肝纤维化患者的外周血中miR-571表达显著升高,联合FIB-4指数对肝纤维化具有一定临床诊断价值。

Abstract:

Objective To study the diagnostic value of miR-571 for liver fibrosis by detecting miR-571 expression in the peripheral blood of patients with liver fibrosis. Methods From December 2022 to September 2023, 40 patients with liver fibrosis, 40 patients with chronic hepatitis, and 40 healthy controls were chosen as research subjects. The expression level of miR-571 in peripheral blood was detected using a real-time quantitative polymerase chain reaction, and the relative expression of miR-571 in each group was evaluated. The Spearman correlation method was utilized to examine the relationship between miR-571 and clinical detection indices. To assess the capacity of miR-571 and the multivariate diagnostic model to identify liver fibrosis, binary logistic regression was used to create a multivariate diagnostic model, and ROC curves were generated. Results The expression of miR-571 was significantly higher in the liver fibrosis group than in the healthy control and hepatitis groups, and the difference was statistically significant (P < 0.001). The expression level of miR-571 was positively connected with ALT, APRI score, and FIB-4 index (r = 0.23, 0.30, 0.22, P < 0.05) and negatively correlated with PLT (r = -0.19, P < 0.05) according to Spearman correlation analysis. Logistic regression research revealed that miR-571 and the FIB-4 index were independent risk factors for liver fibrosis. The AUC for miR-571 to diagnose fibrosis was 0.91 (95% CI: 0.85 ~ 0.96), while the AUC for miR-571 paired with the FIB-4 index was 0.94 (95% CI: 0.90 ~ 0.98). Conclusion MiR-571 expression was shown to be considerably higher in the peripheral blood of hepatic fibrosis patients, and the combined FIB-4 index offers some clinical diagnostic value for hepatic fibrosis.
