贵阳市2889例全血Zn、Fe、Ca、Mg、Cu含量调查分析

目的了解本地区不同年龄性别人群体内锌（Zn）、铁（Fe）、钙（Ca）、镁（Mg）、铜（Cu）元素的含量及其分布特点。方法采用阳极溶出伏安法（anodicstrippingvoltammetry，ASV）检测6种微量元素的含量。结果各元素中以缺Ca最多，其次为Zn、Fe、Cu缺乏。不同年龄之间Zn、Fe、Ca、Cu元素缺乏有显著性差异（P〈0．05），Mg元素差异无显著性（P〉0．05）。Zn元素水平有较大的年龄阶梯，Zn有随年龄增加而递减的趋势，年龄越大，血中Zn水平越低。30岁以下人群血清铁明显低于其他各年龄人群。60岁以上人群Ca含量明显减少。不同性别之间血清Ca、Mg、Cu元素差异无统计学意义（P〉0．05），而Zn、Fe差异有统计学意义（P〈0．05）。结论不同年龄之间全血Zn、Fe、Ca、Cu元素缺乏有显著性差异，Mg元素差异无统计学意义；不同性别之间全血Zn、Fe元素缺乏有显著性差异，Ca、Mg、Cu元素差异无统计学意义。其检验结果可作为临床诊断和分析病因研究的重要参考依据。

2889 cases of whole blood zinc, iron, calcium, magnesium, copper content of investigation and analysis in Guiyang

Objective To understand the different age - sex groups in this region in vivo of zinc, iron, calcium, magnesium, copper content and its distribution characteristics. Methods Anodic stripping voltammetry （ anodic stripping vol- tammetry, ASV）. Results The element to calcium deficiency, followed by zinc, iron, and copper deficiency. Among the different age groups of zinc, iron, calcium, copper lack of significant difference （ P 〈 0. 05 ） , magnesium was no significant difference （ P 〉 0. 05 ）. Zinc level in the older age ladder, zinc increased with age decreasing trend of older, lower the level of zinc in the blood. People under the age of 30 serum ferritin was significantly lower than other age groups. 60 years of age were significantly less Ca. Different between the sexes of serum calcium, magnesium, copper was no significant difference （ P 〉 0. 05 ） , while zinc, iron, a significant difference （ P 〈 0. 05 ）. Conclusion The different ages of whole blood zinc, iron, calcium, magnesium, copper lack of significant differences in magnesium was no significant difference; differences between the sexes in whole blood zinc, iron and the lack of significant differences, calcium, magnesium, Copper difference was not significant. The test results can be used as clinical diagnosis and cause of the disease an important reference.
