    [摘要] 目的 探討同型半胱氨酸(homocysteine，Hcy)水平对脑梗死患者脑动脉狭窄程度和硬化状况的影响。 方法 选取2019年1月～2019年12月在我院诊治的脑梗死患者82例作为研究对象，根据血浆Hcy的水平，分为观察组(Hcy>15 μmol/L，42例)和对照组(Hcy 5～15 μmol/L，40例)，采用磁共振血管成像(Magnetic resonance angiography，MRA)测定血管的狭窄程度并采用彩色多普勒超声仪测定颈动脉斑块硬化程度，并采用Pearson分析Hcy水平与脑动脉狭窄程度和硬化状况的相关性。 结果 与对照组相比，观察组患者的无狭窄率显著降低(7.14% vs 32.50%)，重度狭窄率(54.76% vs 30.00%)和总狭窄率(92.86% vs 67.50%)显著升高，差异有统计学意义(P15 mol/L， n=42) and the control group(Hcy 5-15 μmol/L， n=40) according to the plasma Hcy level. Magnetic resonance angiography(MRA) was used to determine the degree of vascular stenosis and color Doppler ultrasonography was used to determine the degree of carotid plaque sclerosis. Pearson was used to analyze the correlation between the hcy level and the degree of cerebral artery stenosis and cerebral arteriosclerosis. Results Compared with the control group ......
