摘　　要：目的探讨血清同型半胱氨酸(Hcy)水平与颈动脉粥样硬化(CAA)的关系,及叶酸、维生素B12干预后的变化。方法测定169例脑梗死患者(脑梗死组)及110名正常对照者(正常对照组)血清Hcy、叶酸、维生素B12水平;应用彩色多谱勒显像仪对脑梗死患者颈动脉进行检测;分析血清Hcy与叶酸、维生素B12水平以及与CAA程度的关系;观察叶酸、维生素B12干预4周后伴有高Hcy血症的脑梗死患者血清Hcy水平的变化。结果与正常对照组比较,脑梗死组血清Hcy水平明显增高(P<0.01);随着CAA程度增加,血清Hcy水平增高,叶酸、维生素B12水平下降;血清Hcy水平与叶酸、维生素B12水平呈负相关(r=-0.31,P<0.05;r=-0.47,P<0.01),与CAA程度呈正相关(r=0.58,P<0.05);干预治疗后血清Hcy水平显著下降(P<0.01)。结论血清Hcy水平增高是CAA危险因素之一;补充叶酸、维生素B12可降低血清Hcy水平。Objective To explore the relationship between the level of serum homocysteinaemia(Hcy) and the carotid artery atherosclerosis(CAA),and its change after intervention therapy with folate acid and VitaminB12 (VitB12). Methods The levels of serum Hcy,folate acid and VitB12 were measured in 169 patients with cerebral infarction(CI group) and 110 normal controls(NC group). The condition of carotid arteries was checked by color dopper flow image in CI group. The relationship between the level of serum Hcy and fola...
