摘要:

目的 探讨血管性帕金森综合征(VP)患者血清神经丝蛋白轻链(NFL)、胱抑素C(Cys C)、脂蛋白相关性磷脂酶A2(Lp-PLA2)水平变化及其临床意义。方法 选取2018年1月—2022年1月河北北方学院附属第一医院VP患者60例(VP组)、帕金森病(PD)患者60例(PD组)和健康体检者50名(对照组)。收集所有研究对象的一般资料,并检测NFL、Cys C、Lp-PLA2、总胆固醇(TC)、三酰甘油(TG)、尿酸(UA)、空腹血糖、糖化血红蛋白(HbA1c)。采用蒙特利尔认知量表(MoCA)评估患者认知功能。采用帕金森病评定量表运动症状部分(UPDRS-Ⅲ)评估患者运动障碍程度。采用Pearson相关分析评估各项目之间的相关性。采用Logistic回归分析评估VP发生的影响因素。采用受试者工作特征(ROC)曲线评价各项指标单项检测和联合检测诊断VP和PD的效能。结果 对照组、PD组、VP组血清NFL、Cys C、Lp-PLA2水平均依次升高(P<0.001)。VP组MoCA评分低于PD组(P<0.05),UPDRS-Ⅲ评分高于PD组(P<0.001)。其他指标3组之间差异均无统计学意义(P>0.05)。NFL、Cys C、Lp-PLA2、MoCA评分、UPDRS-Ⅲ评分均是VP发生的独立危险因素(P<0.05)。NFL、Cys C、Lp-PLA2水平与MoCA评分呈负相关(r值分别为-0.396、-0.527、-0.258,P<0.001),与UPDRS-Ⅲ评分呈正相关(r值分别为0.562、0.428、0.344、P<0.001)。血清NFL、Cys C、Lp-PLA2水平和MoCA评分、UPDRS-Ⅲ评分单项检测和联合检测诊断VP的曲线下面积(AUC)分别为0.616、0.778、0.815、0.504、0.543、0.958,5项指标单项检测和联合检测诊断PD的AUC分别为0.610、0.703、0.685、0.379、0.404、0.802。结论 VP患者血清NFL、Cys C、Lp-PLA2水平均异常升高,且与患者病情严重程度有关。上述3项指标联合MoCA评分、UPDRS-Ⅲ评分对VP有较高的辅助诊断价值。

Abstract:

Objective To investigate the changes of serum neurofilament light (NFL),cystatin C (Cys C) and lipoprotein-associated phospholipase A2 (Lp-PLA2) levels in patients with vascular Parkinsonism (VP)and their clinical significance. Methods From January 2018 to January 2022,60 VP patients (VP group),60 Parkinson's disease(PD) patients (PD group) and 50 healthy subjects (control group) were enrolled from the First Affiliated Hospital of Hebei North University. The general data of all the subjects were collected,and NFL,Cys C,Lp-PLA2,total cholesterol (TC),triglyceride (TG),uric acid (UA),fasting blood glucose and glycated hemoglobin A1c (HbA1c) were determined. The patients' cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). The Unified Parkinson's Disease Rating Scale-Ⅲ(UPDRS-Ⅲ) was used to evaluate the degree of dyskinesia. Pearson correlation analysis was used to evaluate the correlation between indexes. Logistic regression analysis was used to evaluate the influence factors of VP. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy of single and combined determinations of VP and PD. Results The levels of serum NFL,Cys C and Lp-PLA2 in control group,PD group and VP group were increased successively (P<0.001). The MoCA score of VP group was lower than that of PD group (P<0.05),and the UPDRS-Ⅲ score was higher than that of PD group (P<0.001). There was no statistical significance in the other indexes among the 3 groups (P>0.05). NFL,Cys C,Lp-PLA2,MoCA score and UPDRS-Ⅲ score were all independent risk factors for VP (P<0.05). The levels of NFL,Cys C and Lp-PLA2 were negatively correlated with MoCA score (r = -0.396,-0.527 and -0.258,P<0.001),and they were positively correlated with UPDRS-Ⅲ score (r =0.562,0.428 and 0.344,P<0.001). The areas under curves (AUC) of serum NFL,Cys C,Lp-PLA2,MoCA score and UPDRS-Ⅲ score were 0.616,0.778,0.815,0.504,0.543 and 0.958,respectively. The AUC of single and combined determinations of 5 indexes for PD diagnosis was 0.610,0.703,0.685,0.379,0.404 and 0.802,respectively. Conclusions he levels of serum NFL,Cys C and Lp-PLA2 of VP patients are increased abnormally,which are related to the severity of patients' disease. The 3 indexes combined with MoCA score and UPDRS-Ⅲ score have good diagnostic value for VP.
