缺血性脑血管是多因素所致的疾病,动脉粥样硬化是本病的基本病因,高脂血症增加血液粘滞度,可加速动脉粥样硬化的进程,是脑梗死的独立危险因素。近年来的研究表明,血清同型半胱氨酸(Homocysteine,Hcy)水平升高可通过多种机制引发各种血管病变,是心脑血管疾病的独立危险因素[1],为进一步探讨血清同型半胱氨酸(Hcy)水平变化与 Ischemic cerebrovascular disease is a multifactorial disease, atherosclerosis is the basic cause of the disease, hyperlipidemia increased blood viscosity, can accelerate the process of atherosclerosis, is an independent risk factor for cerebral infarction . In recent years, studies have shown that serum homocysteine ​​(Hcy) levels increased by a variety of mechanisms can lead to a variety of vascular lesions, cardiovascular and cerebrovascular disease is an independent risk factor [1], to further explore the serum homomorphic Cystine (Hcy) level changes and
