缺血性卒中急性期血浆神经递质水平的病例对照研究
目的：通过病例对照的方式研究缺血性卒中急性期血浆神经递质水平与正常人群之间的差异，同时研究不同严重程度卒中患者的血浆递质水平的差异。方法选取连续入组、发病在14d内的急性缺血性卒中患者，采集急性期的血样标本，通过液相色谱-高分辨质谱外标法测量比较卒中组以及正常对照组血浆内的5-羟色胺、去甲肾上腺素、谷氨酸和γ-氨基丁酸4种神经递质的浓度。同时比较不同卒中严重程度患者的4种神经递质浓度。结果共268例缺血性卒中患者入组，其急性期血浆神经递质与正常对照组相比，血浆5-羟色胺（t=2.289，P=0.023）、去甲肾上腺素（t=0.0903，P=0.367）和谷氨酸有上升趋势（t=0.277， P=...

Methods Consecutively recruited and less than 14 d acute ischemic stroke patients were selected. Blood samples were harvested from these subjects at the acute stage of stroke. The plasma levels of four neurotransmitters （i.e. 5-hydroxytryptamine, norepinephrine, glutamate, andγ-aminobutyric acid） were determined by using liquid chromatography-high-resolution mass spectrometry in the patients and normal controls. The neurotransmitter levels were also compared between the different stroke severity groups. Results A total of 268 patients enrolled in our study. Compared with the normal controls, the patients with acute ischemic stroke had signiifcantly higher level of 5-hydroxytryptamine （t=2.289, P=0.023） and lower level ofγ |
