观测了大连市175例50岁上下两年龄组成人血清三脂酰甘油、磷脂、胆固醇及各种脂肪酸含量。并对高脂血与ω-3型多不饱和脂肪酸水平的关系,特别是与花生四烯酸(AA)、二十碳五烯酸(EPA)或二十二碳六烯酸(DHA)之间的关系作了分析。结果表明大连居民血清中主要脂肪酸组成基本符合文献报道中沿海城市的类型。但EPA和DHA明显偏低。在体内他们虽然可从其它营养必需脂肪酸少量转化而来,但远远不能满足机体的需要,故人体所需EPA和DHA主要靠摄入。本文分析显示EPA和DHA与TG、TC的水平呈负相关。故EPA/AA和DHA/AA的比值可作为ω-3系多不饱和脂肪酸摄取及预测心血管疾病的指标,对营养调理及临床防治疾病有指导意义。
The serum triglycerides, phospholipids, cholesterol and fatty acids in 175 adults aged 50 years and older in Dalian were observed. And the relationship between hyperlipemia and the level of ω-3 polyunsaturated fatty acids, especially with arachidonic acid (AA), eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) The relationship between the analysis. The results showed that the main fatty acid composition in Dalian residents basically accorded with the types of coastal cities reported in the literature. However, EPA and DHA were significantly lower. In the body although they can be a small amount of other essential fatty acids from nutrients transformed, but far from being able to meet the needs of the body, so the body mainly EPA and DHA intake. This analysis shows that EPA and DHA and TG, TC levels were negatively correlated. Therefore, the ratio of EPA / AA and DHA / AA can be taken as an index of the uptake of ω-3 polyunsaturated fatty acids and prediction of cardiovascular diseases, which is of guiding significance for nutrition regulation and clinical prevention and treatment of diseases.
