【摘要】 目的 探讨急性脑梗死患者血清叶酸、VitB12水平及其临床意义。方法 对88例首次发病的急性缺血性脑中风患者分为两个亚组，动脉硬化性脑梗死组32例，腔隙性脑梗死组56例，并设对照组35例，入院后用罗氏公司Elecsys 2010型全自动电化学发光免疫分析仪测定血清叶酸、VitB12浓度。结果 (1)脑梗死组、腔隙性脑梗死组的血清叶酸、VitB12平均水平均显著低于对照组(P值分别<0.01、0.05)；(2)脑梗死组的血清叶酸、VitB12平均水平显著低于腔隙性脑梗死组(P值均<0.05)。结论 血清叶酸、VitB12可作为急性脑梗死、腔隙性脑梗死比较特异重要的监测指标，对临床鉴别脑梗死与腔隙性脑梗死有一定的帮助,并对脑梗死的预防、治疗可能有一定的指导意义。

    【Abstract】 Objective To explore the association between the level of folate,VitB12 and acute cerebral infarction disease.Methods 88 acute ischemic cerebrovascular stroke disease events were disparted in two subgroups,32 of arteriosclerotic cerebral infarction,56 of lacunar cerebral infarction,and 35 contrast group were set up.All the participants’ serum folate,VitB12 were measured when they entered the hospital.Results (1)The level of serum folate,VitB12 in cerebral infarction、lacunar cerebral infarction were evidently lower than contrast group.(P respectively<0.01,0.05).(2)The level of serum folate,VitB12 in cerebral infarction were significantly lower than those in lacunar cerebral infarction(P<0.05).Conclusion Folate and VitB12 could be a particular monitor factor for acute cerebral infarction and lacunar cerebral infarction disease,it is greatly helpful to distingui acute cerebral infarction and lacunar cerebral infarction clinically and also for prevention,therapy of ischemic cerebrovascular stroke disease. ......
