[摘要] 目的 分析缺血性脑血管病患者颈动脉粥样硬化程度与血浆神经肽Y(NPY)水平的相关性。 方法 采用放射免疫法检测缺血性脑血管病患者[包括急性脑梗死、短暂性脑缺血发作(TIA)和颈动脉粥样硬化患者]和健康体检者(对照组)血浆NPY水平；采用彩色多普勒超声检测缺血性脑血管病患者颈动脉内膜中层厚度(IMT)。 结果 缺血性脑血管病患者NPY水平较对照组明显升高(P < 0.01)；随着颈动脉粥样硬化程度加重，血浆NPY水平呈现增高趋势；颈动脉重度狭窄患者NPY水平与轻、中度狭窄患者相比差异有统计学意义(P < 0.05)；急性脑梗死和TIA患者较单纯颈动脉粥样硬化患者血浆NPY明显升高(P < 0.05)。缺血性脑血管病患者中血浆NPY水平与IMT值呈正相关关系(r = 0.163、0.245、0.179，P < 0.05)。 结论 NPY可反映颈动脉粥样硬化的程度且参与颈动脉粥样硬化的病理生理过程。

[Abstract] Objective To analyze the correlation between the level of blood plasma neuropeptide Y (NPY) and carotid atherosclerosis degree in patients with ischemic cerebrovascular disease. Methods The blood plasma NPY level of patients with ischemic cerebrovascular disease [patients with acute cerebral infarction, transient ischemia attach (TIA) and carotid atherosclerosis were include] and health people (control group) was measured by radioimmunity. The intima-medium thickness (IMT) of carotid artery in patients with ischemic cerebrovascular disease was detected by colour Doppler ultrasonography. Results Compared with control group, the blood plasma NPY level of ischemic cerebrovascular disease patients increased significantly (P < 0 ......
