摘要:

目的 探讨血清脂蛋白相关磷脂酶A2(Lp-PLA2)和超氧化物歧化酶(SOD)在脑小血管病(CSVD)患者轻度认知障碍(MCI)中的临床价值。方法 选取CSVD患者120例,根据患者入院时的蒙特利尔认知评估量表(MoCA)评分结果分为MCI组(MoCA评分<26分)和对照组(MoCA评分≥26分)。收集患者的一般资料、既往病史,检测其血浆Lp-PLA2和SOD水平。采用Pearson相关分析评估Lp-PLA2、SOD与MoCA评分的相关性。采用多因素Logistic回归分析评估MCI的危险因素。采用受试者工作特征(ROC)曲线评价Lp-PLA2、SOD辅助诊断MCI的价值。结果 MCI组Lp-PLA2水平高于对照组(P<0.05),SOD水平低于对照组(P<0.05)。多因素Logistic回归分析结果显示,Lp-PLA2是MCI的危险因素[比值比(OR)=3.241,95%可信区间(CI)为2.014~5.362],SOD是MCI的保护性因素(OR=0.652,95%CI为0.407~0.964)。Pearson相关分析结果显示,Lp-PLA2与MoCA评分呈负相关(r=-0.535,P=0.017),SOD与MoCA评分呈正相关(r=0.684,P=0.008)。Lp-PLA2、SOD单项检测和联合检测诊断MCI的曲线下面积(AUC)分别为0.813、0.738、0.903,联合检测效能优于单项检测(P<0.05)。结论 Lp-PLA2和SOD均为CSVD患者MCI的影响因素,两者联合检测有助于MCI的辅助诊断。

Abstract:

Objective To evaluate the clinical value of serum lipoprotein-related phospholipase A2(Lp-PLA2) combined with superoxide dismutase(SOD) in predicting mild cognitive impairment (MCI)in cerebral small vessel disease(CSVD). Methods According to the Montreal Cognitive Assessment(MoCA) score at admission,a total of 120 patients with CSVD were enrolled and classified into MCI group(MoCA score <26) and control group(MoCA score ≥26). The general information and past medical history of the patients were collected,and plasma Lp-PLA2 and SOD levels were determined. Pearson correlation analysis was used to evaluate the correlation between Lp-PLA2,SOD and MoCA score. Multivariate Logistic regression analysis was used to evaluate the risk factors for MCI. Receiver operating characteristic(ROC) curve was used to evaluate the values of Lp-PLA2 and SOD in the auxiliary diagnosis of MCI. Results The level of Lp-PLA2 in MCI group was higher than that in control group(P<0.05),and the level of SOD was lower than that in control group(P<0.05). Multivariate Logistic regression analysis showed that Lp-PLA2 [odds ratio(OR)=3.241,95% confidence interval(CI) 2.014-5.362] were independent risks of MCI,and SOD(OR=0.652,95%CI 0.407-0.964) was an independent protective factor for MCI. Lp-PLA2 was negatively correlated with MoCA score(r=-0.535,P=0.017),and SOD was positively correlated with MoCA score(r=0.684,P=0.008). The areas under curves(AUC) of Lp-PLA2,SOD single determinations and combined determination in the diagnosis of MCI were 0.813,0.738 and 0.903,respectively,and the efficiency of combined determination was better than those of single determinations(P<0.05). Conclusions Lp-PLA2 and SOD are influence factors for MCI in CSVD patients,and the combined determination may play a role in the diagnosis of MCI.
