摘要
目的:了解知识分子血清同型半胱氨酸水平及其相关影响因素.方法:在天津、广州、成都三座城市大专院校、科研院所选择年龄40～69岁,138名具有高级职称的知识分子作研究对象,对其应激水平、血清同型半胱氨酸、唾液皮质醇水平以及相关影响因素进行调查分析.结果:研究对象血清同型半胱氨酸平均水平为20.6±0.8μmo1/L.高水平唾液皮质醇组的血清同型半胱氨酸水平明显高于低水平唾液皮质醇组.各年龄组之间比较,40～49岁年龄组受试者血清同型半胱氨酸水平最高.男性血清同型半胱氨酸平均水平高于女性.将受试者血清同型半胱氨酸水平进行地区间的比较,天津受试者的血清同型半胱氨酸平均水平最高,成都居中,广州最低.结论:知识分子血清同型半胱氨酸水平显著高于正常人群.应激水平、性别、居住地对同型半胱氨酸水平有明显影响.
Objective： To observe the concentration of serum homocysteine in intellectuals and its influential factors. Method： Serum homocysteine and saliva cortisol concentrations were measured in 138 intellectuals from three cities, Tianjin, Guangzhou, and Chengdu. All the subjects had senior titles of technical post, aged 40-69 years. Results： The mean value of serum homocysteine concentration in intellectuals was 20.6±0.8μmol/L, higher than that of normal people. The group of high saliva cortisol concentration had higher serum homocysteine concentration. The mean value of homocysteine concentration was highest in 40-49 years old. Men had higher homocysteine level than women. According to the mean value of homocysteine concentration among different cities, Tianjin was highest, Chengdu medium, Guangzhou lowest. Conclusion： The serum homocysteine concentration of intellectuals is higher than that of normal people. The stress level, gender and resident cities might be the influencial factors of serum homocysteine concentration in Chinese intellectuals.
