目的 研究血同型半胱氨酸(Hcy)与动脉硬化型缺血性脑卒中的关系。方法 临床纳入58例我院2014年3月至2017年3 月期间收治的动脉硬化型缺血性脑卒中患者作为观察组，另纳入同期来我院体检中心进行体检的58例健康志愿者作 为对照组。分别对两组对象进行血Hcy、空腹血糖(FBG)以及血脂等水平检测，观察血Hcy与动脉硬化型缺血性脑卒 中的关系。结果 观察组患者血Hcy水平明显高于对照组，P＜0.05；而FBG、TC、TG、LDL-C以及HDL-C水平与对照组 无差异，P＞0.05。血Hcy与动脉硬化型缺血性脑卒中呈明显正相关，P＜0.05；而其他指标(FBG、血脂各指标等) 与动脉硬化型缺血性脑卒中无明显相关性，P＞0.05。结论 动脉硬化型缺血性脑卒中患者Hcy水平明显高于正常人 群，血Hcy水平越高，患者病情越严重。

Objective To study the correlation of the Hcy (homocysteine) level with arteriosclerosis-associated cerebral ischemic stroke. Methods 58 patients with arteriosclerosis-associated cerebral ischemic stroke treated from March 2014 to March 2017 in our hospital were selected (observation group). 58 healthy check-ups in our medical examination center were selected (control group). The index of Hcy, FBG and blood lipid for two groups were observed; the correlation of Hcy with the arteriosclerosis-associated cerebral ischemic stroke was analyzed. Results The index of Hcy for observation group was significantly higher than control group (P<0.05); the index of FBG, TC, TG, LDL-C and HDL-C for two groups were not significantly different (P>0.05), the index of Hcy had a close correlation with the arteriosclerosis-associated cerebral ischemic stroke(P<0.05); the other index (FBG, blood lipid, etc) had no obvious correlation with the arteriosclerosis-associated cerebral ischemic stroke (P>0.05). Conclusion The index of Hcy for arteriosclerosis-associated cerebral ischemic stroke patients is significantly higher than healthy group; the higher the Hcy level is, the more serious the illness condition is.
