【摘要】:目的: 通过流式细胞技术检测缺血性卒中患者急性期外周血血浆中细胞膜微粒(内皮细胞膜微粒与血小板细胞膜微粒)的水平,并探讨其在缺血性卒中急性期发生、发展中的意义和作用。 方法: 1、病例选择:选取2013年3月至12月在我院神经内科住院的缺血性卒中患者(首次发病,持续时间2周以内,新入院)为研究对象,并排除脑炎、自身免疫性疾病、血液病、严重肝、肾功能障碍、恶性肿瘤及恶病质等。共有84例纳入实验组。对照组我们选取来我院门诊体检者40例,具备以下特点:有一个或多个脑血管高危因素(如高血压、糖尿病、冠心病、高血脂、吸烟等)且无卒中史。 2、实验分组:按NIHSS评分将实验组分为轻度脑梗死组52例(NIHSS≤5分)和中重度脑梗死组32例(NIHSS≥6分),选取40例性别、年龄相匹配的体检者作为对照组。利用流式细胞仪技术检测病例组与对照组血浆内皮细胞膜微粒(APC-CD144+)与血小板细胞膜微粒(PE-CD41a+)水平。 3.统计学分析:数据以SPSS16.0软件包处理,定量资料以均数±标准差(ˉx±S)表示,定性资料以计数或率表示。采用X2检验、t检验、方差分析(one-way ANOVA)进行统计学分析,两变量相关采用sperman秩相关。检验水准为α=0.05,以P<0.05认为差别有统计学意义。 结果: 1.实验组血TCHO、HCY水平稍高于对照组,而血HDL-C水平低于对照组,,余基线资料比较差别无统计学意义(P>0.05) 2.实验组外周血血浆中内皮细胞膜微粒(EMPs)与血小板细胞膜微粒(PMPs)水平明显高于对照组(P<0.01) 3.经NIHSS评分分组后,轻度脑梗死组与中重度脑梗死组血浆中EMPs和PMPs水平有显著差异(P<0.05)且EMPs与PMPs水平的高低与缺血性卒中急性期的严重程度呈正相关(P<0.01,r=0.617),(P<0.01,r=0.535)。 结论: 1.缺血性卒中患者急性期外周血血浆中EMPs与PMPs水平高于对照组,且其水平的高低与疾病的严重程度呈正相关。 2. EMPs与PMPs可能参与了缺血性卒中急性期的发生、发展过程,其可能可作为评估患者病情的一项指标。
[Abstract]:Objective: Flow cytometry was used to detect the level of plasma membrane particles (endothelial cell membrane particles and platelet membrane particles) in peripheral blood of patients with acute ischemic stroke, and to explore their occurrence in the acute phase of ischemic stroke. Significance and role of development Methods: 1. Case selection: patients with ischemic stroke (first onset, duration less than 2 weeks, new admission) who were hospitalized in neurology department of our hospital from March to December 2013 were selected as study subjects, encephalitis, autoimmune disease and hematologic disease were excluded. Severe liver, renal dysfunction, malignant tumors and cachexia. A total of 84 cases were included in the experimental group. In the control group, 40 patients were selected for outpatient examination in our hospital, with the following characteristics: one or more cerebrovascular risk factors (such as hypertension, diabetes, coronary heart disease, hyperlipidemia, smoking, etc.) and no history of stroke. 2, experimental group: according to NIHSS score, the experimental group was divided into mild cerebral infarction group (52 cases) and moderate and severe cerebral infarction group (32 cases with NIHSS 鈮
