目的 探讨帕金森病患者外周血浆及红细胞中α-突触核蛋白(α-syn)寡聚体含量对帕金森病诊断以及与病程、疾病严重程度的相关性.方法 2013年3月至2014年12月,采集30例帕金森病患者(患者组)及30例健康体检者(对照组)血液,采用酶联免疫吸附测定法检测血浆及红细胞中α-syn寡聚体含量.结果 对照组血浆及红细胞中α-syn寡聚体含量低于患者组(t>2.346,P<0.05);两组红细胞中α-syn寡聚体含量高于血浆中含量(t>2.242,P<0.05);患者组血浆及红细胞中α-syn寡聚体含量与病程、Hoehn-Yahr分期、帕金森病综合评分量表第3部分评分、帕金森病非运动症状问卷评分、简易精神状态检查评分均无相关性(P>0.05).结论 帕金森病患者外周血浆及红细胞中α-syn寡聚体含量有助于帕金森病诊断,但不具有监测疾病进展价值.%Objective To investigate the level of alpha-synuclein (α-syn) oligomers in peripheral blood plasma and red blood cells (RBC) in patients with Parkinson's disease (PD), and the value of it for diagnosis and evaluation of PD. Methods From March, 2013 to De-cember, 2014, peripheral blood samples were collected from 30 PD patients and 30 healthy coutrols, and the level ofα-syn oligomers in plas-ma and RBC was detected with enzyme linked immunosorbent assay. Results The level of α-syn oligomers was less in both plasma and RBC in the controls than in the patients (t>2.346, P<0.05), and was more in RBC than in plasma in both the controls and the patients (t>2.242, P<0.05). The level ofα-syn oligomers of patients did not correlate with their course, Hoehn-Yahr Stage, the scores of Unified Parkin-son Disease Rating Scale Part 3, Non-Motor Symptom Quest and Mini-Mental State Examinatlon, both in plasma and RBC (P>0.05). Con-clusion The level ofα-syn oligomers in peripheral RBC and plasma may be helpful for diagnosis of PD, but less for the evaluation of the ill-ness.
