研究目的:

观察高血压患者以及正常对照24小时动态血压变异,磁共振确定脑白质脱髓鞘及脑萎缩程度;MMSE、MoCA、CTB等评价认知功能;留取静脉血,测定血清Aβ、sLRP-1、sRAGE 、NO、内皮素-1、ROS水平,研究血压变异性与Aβ转运的关系及其机制,为防治高血压引起的认知功能障碍提供依据。  

Objectives of Study:

Through the longitudinal observation of hypertensive patients and healthy people,we can compare the difference between them from surveying the 24 hours ambulatory blood pressure variation , assessing the degree of cerebral white matter demyelination and brain atrophy; evaluating the cognitive functions using MMSE, MoCA, CTB, and so on. And combining with the determination of sRAGE, Amyloid beta peptide, sLRP - 1 ,NO, endothelin - 1, ROS level, we can discover the effects of blood pressure variability on plasma amyloid beta peptide and its mechanism .Those observations may offer new opportunities for better control the blood pressure which may lower the risk of cognitive impairment or dementia.
