摘要:

目的 探讨血清C1q肿瘤坏死因子相关蛋白3(CTRP3)、镍纹蛋白样蛋白(Metrnl)在2型糖尿病(T2DM)并发微血管病变诊断中的价值。方法 选取2021年8月—2024年1月唐山市开滦总医院2型糖尿病(T2DM)患者215例(T2DM组)、健康体检者215名(正常对照组)。根据是否发生微血管病变将T2DM患者分为病变组(104例)和非病变组(111例)。收集所有研究对象的临床资料,并检测血脂和血清CTRP3、Metrnl水平。采用多因素Logistic回归分析评估T2DM患者并发微血管病变的影响因素。采用受试者工作特征(ROC)曲线评估血清CTRP3、Metrnl诊断T2DM患者并发微血管病变的效能。结果 T2DM组血清CTRP3、Metrnl水平显著低于正常对照组(P<0.001),2个组其他指标差异均无统计学意义(P>0.05)。与非病变组比较,病变组血清CTRP3、Metrnl 、高密度脂蛋白胆固醇(HDL-C)水平降低(P<0.001),血清总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)水平升高(P<0.001),2个组之间其他指标差异均无统计学意义(P>0.05)。血清CTRP3、Metrnl水平降低均是T2DM患者并发微血管病变的危险因素[比值比(OR)值分别为0.276、0.124,95%可信区间(CI)分别为0.138~0.552、0.055~0.278,P<0.001]。血清CTRP3、Metrnl单项检测和联合检测诊断T2DM患者并发微血管病变的曲线下面积(AUC)分别为0.816、0.810、0.882。结论 血清CTRP3、Metrnl联合检测在T2DM并发微血管病变的诊断中具有较高的价值。

Abstract:

Objective To investigate the role of serum C1q tumor necrosis factor-related protein 3(CTRP3)and meteorin-like protein(Metrnl)in the diagnosis of type 2 diabetes mellitus(T2DM)complicated with microvascular lesions. Methods A total of 215 patients with T2DM (T2DM group) and 215 healthy subjects (healthy control group) were enrolled from Kailuan General Hospital from August 2021 to January 2024. T2DM patients were classified into lesion group(104 cases)and non-lesion group(111 cases)based on whether they had microvascular lesions. The clinical data were collected,and serum CTRP3 and Metrnl levels were determined. Multivariate Logistic regression analysis was used to evaluate the influencing factors of microvascular lesions in T2DM patients. Receiver operating characteristic (ROC) curve was used to evaluate the efficacy of serum CTRP3 and Metrnl in diagnosing microvascular lesions in T2DM patients. Results The serum CTRP3 and Metrnl levels in T2DM group were lower than those in healthy control group (P<0.001),and there was no statistical significance in the other indicators between the 2 groups(P>0.05). Compared with non-lesion group,the serum CTRP3,Metrnl and high-density lipoprotein cholesterol(HDL-C)levels in lesion group were decreased(P<0.001),while the serum total cholesterol(TC),triglyceride(TG)and low-density lipoprotein cholesterol(LDL-C)levels were increased (P<0.001). There was no statistical significance in the other indicators between the 2 groups(P>0.05). Decreased serum CTRP3 and Metrnl levels were risk factors for microvascular lesions in T2DM patients [odds ratios(OR)were 0.276 and 0.124,95% confidence intervals(CI)were 0.138-0.552 and 0.055-0.278,P<0.001]. The areas under curves (AUC) of single and combined determinations of serum CTRP3 and Metrnl for diagnosing microvascular lesions in T2DM patients were 0.816,0.810 and 0.882,respectively. Conclusions The combined determination of serum CTRP3 and Metrnl plays a role in the diagnosis of microvascular lesions in T2DM.
