[摘要] 目的 研究血浆同型半胱氨酸水平与老年脑卒中的关系。 方法 选取2013年1月~2015年12月收治的 140 例老年脑卒中患者,进行血浆同型半胱氨酸水平检测,对照组为60例老年健康体检者,比较两组血浆同型半胱氨酸水平。 结果 脑卒中组和对照组同型半胱氨酸水平分别为(15.79±4.73)μmol/L、(10.57±2.53)μmol/L,高同型半胱氨酸血症分别为 93 例(66.4%)、11例(18.3%),脑卒中人群血浆同型半胱氨酸水平与对照组比较差异显著(P<0.01)。脑卒中组男女同型半胱氨酸水平分别为(18.85±3.51)μmol/L、(12.91±3.86)μmol/L,高同型半胱氨酸血症阳性率男女分别为 62 例(91.18%)、31 例(43.06%),脑卒中组男女同型半胱氨酸水平比较差异显著(P<0.01)。结论 血浆高同型半胱氨酸水平是脑卒中的独立危险因素,对有脑卒中倾向的老年患者常规检测血浆同型半胱氨酸水平,控制高同型半胱氨酸血症,對预防脑卒中的发生有重要临床意义。

[Abstract] Objective To study the relationship between plasma homocysteine level and stroke in the elderly. Methods A total of 140 elderly patients with stroke who were admitted from January 2013 to December 2015 were selected. Plasma homocysteine levels were tested. The control group was 60 elderly patients undergoing health examination. Plasma homocysteine levels were compared between the two groups. Results The levels of homocysteine in stroke group and control group were(15.79±4.73) umol/L and(10.57±2.53) μmol/L respectively. There were 93 cases (66.4%) and 11 cases(18.3%) of hyperhomocysteinemia in the two groups respectively. The differences of the levels of plasma homocysteine in stroke patients were significant compared to those in the healthy control group(P<0.01). The levels of plasma homocysteine in the stroke group were(18.85±3.51) μmol/L and(12.91±3.86) μmol/L in males and females respectively. The positive rates of hyperhomocysteinemia were 62 cases(91.18%) and 31 cases(43.06%) in males and females respectively. The levels of homocysteine in the stroke group were significantly different compared between males and females (P<0.01). Conclusion Plasma homocysteine level is an independent risk factor for stroke. Routine detection of plasma homocysteine levels and control of hyperhomocysteinemia in elderly patients with a tendency to stroke, have important clinical implications for the prevention of stroke.

脑卒中发病率、患病率和死亡率随年龄增长而增加,75岁以上者发病率是45~54岁组的5~8倍[1-2]。同型半胱氨酸(homocysteine,Hcy)是一种含硫氨基酸,它是蛋氨酸和半胱氨酸代谢过程中的重要中间产物。高同型半胱氨酸血症可引起血管内皮功能和代谢紊乱,导致动脉粥样硬化性疾病,是心脑血管疾病的独立危险因素[3]。本文通过测定140例老年脑卒中患者及60例老年健康者血浆同型半胱氨酸水平,研究血浆同型半胱氨酸水平与老年脑卒中的关系。现报道如下。

1 资料与方法

1.1 临床资料

选取2013年1月~2015年12月收治的140例老年脑卒中患者,经头颅CT或MRI明确诊断。其中女72例,男68例;年龄60~88岁,平均(67.09±5.59)岁;对照组:选取60例健康体检的老年人并排除心脑血管疾病、糖尿病和肾脏等疾病,其中女30例,男30例;年龄60~87岁,平均(67.43±5.61)岁。两组性别、年龄等一般资料比较差异无统计学意义(P>0.05),具有可比性。所有受检者近3个月内均未服用过叶酸、维生素B6、维生素B12和降脂等药物。……
