血清M2BPGi联合MRI-DWI预测丙型肝炎患者肝纤维化的临床价值

摘要

Objective To explore and compare the prognostic ability of the serum level of M2BPGi and MRI imaging technology for hepatic fibrosis. Methods 118 patients who were diagnosed as hepatitis C were enrolled from March 2014 to March 2015 in our hospital.Their baseline data were recorded,and they were texted by imaging examination of MRI.Then all patients were followed-up 2 years.The patients were divided into hepatic fibrosis group and control group according to the follow-up results.Univariate analysis and Cox model were used to show that the prognostic factors influencing the prognosis of hepatic fibrosis in patients;meanwhile,the statistical significance factors were calculated by ROC curve.Results The serological markers of IV-C,HA and serum level of M2BPGi in hepatic fibrosis group were higher than those in control group,but its ADC values of liver was lower than those in control group,and the difference was statistically significant(P < 0.05). COX regression analysis showed that the difference of M2BPGi(RR = 4.282,P = 0.003)and ADC values(RR = 0.654,P = 0.004). The ROC analysis of the hepatic fibrosis group and the control group showed that the AUC of the combination was 0.865,the sensitivity and specificity were 95.2%,60.5%,respectively.Conclusion The clinical value the com-bined prognostic of them is of high prognostic efficacy,which is hopeful to be used as an auxiliary prognostic meth-od in clinic.%目的 探究血清M2BPGi与MRI影像学技术预测肝纤维化的临床价值.方法 选取2014年3月至2015年3月就诊丙型肝炎患者118例,收集患者血清学肝纤四项水平和血清M2BPGi的水平,并进行磁共振成像检查,所有患者治疗后随访2年,根据随访结果分为肝纤维化组与对照组.单因素分析及Cox比例风险模型显示影响丙型肝炎患者并发肝纤维化可能性的因素;同时,采用ROC曲线分析其预测丙型肝炎患者并发肝纤维化的敏感性和特异性.结果 肝纤维化组的血清学指标IV-C与HA和血清M2BPGi水平均高于与对照组,MRI的表观扩散系数低于对照组,差异有统计学意义(P<0.05).COX回归分析显示血清M2BPGi水平(RR=4.282,P=0.003)与MRI影像学检查的ADC值(RR=0.654,P=0.004)的差异均有统计学意义.ROC显示二者联合时,AUC为0.865,敏感度为95.2%,特异性为60.5%.结论 血清M2BPGi联合MRI影像学检查预测效能较高,有望应用于临床作为预测丙型肝炎患者肝纤维化的辅助指标之一.
