同型半胱氨酸(Hcy)是必需氨基酸蛋氨酸在人体内代谢的中间产物,是一种血管损伤性氨基酸,Hcy升高可通过损伤内皮细胞激活血小板,促进血栓形成等因素促进动脉粥样硬化形成。高Hcy血症与2型糖尿病大血管病变有密切关系[1,2],是心脑血管疾病的独立危险因素,为此,我们对108例2型糖尿 Homocysteine ​​(Hcy) is the essential amino acid methionine metabolism in the human body is an intermediate product, is a vascular injury of amino acids, Hcy can damage endothelial cells through the activation of platelets, promote thrombosis and other factors to promote atherosclerosis formation . Hyperhomocysteinemia and type 2 diabetes are closely related to macrovascular disease [1,2], is an independent risk factor for cardiovascular and cerebrovascular diseases, therefore, we have 108 cases of type 2 diabetes
