以多因子回归及判别分析研究4地区、4民族八个人群共484人(男、40～59岁)的22种血清氨基酸水平与血压的关系,发现:1.住新疆同一地区的哈萨克、汉、维吾尔族的不同氨基酸水平可能反映其迥异的食物结构;而饮食相仿,住贵州同一山区汉、彝族组间的差别,提示除营养因子外、遗传代谢因子的影响。2.除门冬氨酸及(或)谷氨酸在居高寒山区的贵汉、彝组最高外,其他氨基酸水平在该区均较低,提示可能反映组织较慢的代谢更新率,与其血压、Quetelet指数及血清尿素水平较低也相一致。3.摄入动物蛋白量高的新疆(羊肉为主)或舟山(鱼为主)组人群,氨基酸水平均较高,难以将渔民中心脑血管病罹患率较低完全归因于摄入较多富含硫氨基酸的鱼肉。4.从血压回归方程提示缬、丰胱、丙、苏氨酸可能属升压性;亮、甲硫、苯丙、甘氨酸和谷胺酰胺可能属抗高血压性。
Using multifactor regression and discriminant analysis, we studied the relationship between 22 serum amino acid levels and blood pressure in 484 persons (male, 40-59 years old) in 4 regions and 4 ethnic groups and found that: 1. The different amino acid levels of Uighur people may reflect their different food structures. However, similar diets and differences among Han and Yi ethnic groups living in the same mountain area of Guizhou suggest the influence of genetic metabolic factors in addition to nutritional factors. 2. Except for aspartic acid and / or glutamic acid, the highest level of other amino acids in the Han and Yi groups living in alpine mountain regions are lower in this region, suggesting that it may reflect the slow metabolic rate of tissue replacement and its blood pressure , Quetelet index and lower serum urea levels are also consistent. 3. High intake of animal protein in Xinjiang (mainly mutton) or Zhoushan (fish-based) group of people, high levels of amino acids, it is difficult to lower the prevalence of cerebrovascular disease fisherman center entirely due to more intake Amino acids rich in fish. 4. From the regression equation of blood pressure prompted Valerian, cystine, C, Thr may be booster; light, methylthio, phenylpropyl, glycine and glutamine may be antihypertensive.
