摘要: 目的 研究脑梗死患者同型半胱氨酸(Hcy)水平的变化,以探讨Hcy水平升高是否是脑血管病的独立危险因素,同时观察Hcy与其他传统危险因素的关系,以指导临床治疗及预防。 方法 应用循环酶法测定292例脑梗死患者、80名健康体检者(正常对照组)的血清Hcy水平,同时测定脑梗死传统危险因素如血压、空腹血糖(Glu)、甘油三酯(TG)、总胆固醇(TC)、脂蛋白(a)[Lp(a)]、尿酸(UA)等。采用回归分析方法,用相关系数(r)评价传统指标与Hcy的相关性。采用病例对照的方法进行分析。 结果 脑梗死组血清Hcy水平分别为(18.19±7.26)μmol/L,明显高于正常对照组[(11.23±5.46)μmol/L](P<0.05)。以Hcy>20 μmol/L为高Hcy血症的诊断标准,脑梗死组的发病率为20.5%,而对照组仅为1.2%,二者比较差异有统计学意义(P<0.05)。脑梗死组中男性Hcy[(19.84±7.87)μmol/L]明显高于女性[(12.38±7.42)μmol/L](P<0.05)。年龄、吸烟史、Glu、TG、TC等在2组中差异均无统计学意义(P>0.05)。在脑梗死传统危险因素中,UA、Lp(a)与Hcy呈正相关(r值分别为0.040、0.044,P均<0.05)。而年龄、舒张压、Glu、TG、TC与Hcy无相关性(P>0.05)。 结论 高Hcy血症为脑梗死的独立危险因素,UA、Lp(a)与Hcy关系密切。

Abstract: Objective To study the changes of homocysteine(Hcy) levels in patients with cerebral infarction in order to investigate whether the increase of Hcy is an independent risk factor for cerebrovascular disease,and to observe Hcy and other traditional risk factors for guiding clinical treatment and prevention.   Methods Hcy was determined by cyclic enzymatic method. A total of 292 patients with cerebral infarction were enrolled,and 80 healthy subjects were as control group. The blood pressure,fasting glucose(Glu),triglyceride(TG),total cholesterol(TC),lipoprotein(a) [Lp(a)] and uric acid(UA) were determined. The correlation of traditional indicators and Hcy was analyzed by correlation coefficient(r) with regression analysis. The results of patients with cerebral infarction and control group were analyzed. Results Hcy level was(18.19±7.26)μmol / L in patients with cerebral infarction. The Hcy level in control group was(11.23±5.46) μmol / L(P<0.05). If the Hcy level > 20 μmol/L was settled as high Hcy hematic disease diagnosis standard,the incidence rate in patients with cerebral infarction was 20.5%,and the incidence rate in control group was only 1.2% with statistical difference(P<0.05). In cerebral infarction patients,the Hcy level of males was(19.84±7.87) μmol / L ,which was significantly higher than that of females [(12.38±7.42)μmol / L](P<0.05). Age,smoking history,fasting Glu,TG and TC had no statistical significance(P>0.05). In a variety of traditional risk factors for cerebral infarction,the correlation of UA and Lp(a) with Hcy was positive,and r were 0.040 and 0.044(P<0.05). Age,diastolic blood pressure,Glu,TG and TC had no correlation with Hcy levels(P>0.05). Conclusions High Hcy hyperlipidemia is an independent risk factor for cerebral infarction,UA,Lp(a) and Hcy are closely related.
