项目摘要高脂血症和高同型半胱氨酸(Hcy)血症是动脉粥样硬化(AS)与心血管疾病(CVD)的两项重要危险因素,降低人群血脂和 Hcy 水平有利于 AS 与 CVD 发病及死亡的控制。研究表明补充叶酸可明显降低 Hcy水平,但对血脂谱水平的影响尚无明确结论。本研究 Abstract Hyperlipidemia and hyperhomocysteinemia are two important risk factors of atherosclerosis (AS) and cardiovascular disease (CVD). To reduce the level of blood lipids and Hcy in the population is beneficial to AS and CVD morbidity and mortality control. Studies have shown that folic acid supplementation can significantly reduce the level of Hcy, but the level of lipid profile is not yet conclusive. this research
