采用原子吸收光谱分析法，对闸北区和南汇县中风高危人群（ＳＰＰ）血清微量元素Ｚｎ，Ｃｕ，Ｆｅ和常量元素Ｃａ，Ｍｇ含量作了抽样调查。结果发现闸北区ＳＰＰ的Ｃｕ，Ｃａ，Ｃａ／Ｍｇ明显低于南汇县ＳＰＰ和对照组，而Ｚｎ，Ｆｅ，Ｍｇ，Ｚｎ／Ｃｕ则高于南汇和对照组。Ｃａ，Ｃａ／Ｍｇ与血压呈负相关，而Ｚｎ／Ｃｕ与血压呈正相关；Ｃａ／Ｍｇ与身体指数和胆固醇呈负相关；Ｚｎ，Ｆｅ，Ｚｎ／Ｃｕ与红细胞压积呈正相关；Ｃａ，Ｃａ／Ｍｇ与低密度脂蛋白呈负相关；Ｚｎ，Ｆｅ，Ｚｎ／Ｃｕ与增龄呈正相关。提示脑中风发病与Ｃｕ．Ｃａ较低而Ｚｎ，Ｐｅ，Ｍｇ较高有密切的关系。
Atomic absorption spectroscopy was used to investigate the contents of trace elements Zn, Cu, Fe and Ca, Mg in high risk population of stroke in Zhabei District and Nanhui County. The results showed that SPP Cu, Ca, Ca / Mg in Zhabei District were significantly lower than that in Nanhui County SPP and control group, while Zn, Fe, Mg, Zn / Cu were higher than those in Nanhui and control groups. Ca, Ca and Mg were negatively correlated with blood pressure, while Zn / Cu was positively correlated with blood pressure; Ca / Mg was negatively correlated with body index and cholesterol; Zn, Fe and Zn / Cu were positively correlated with hematocrit; Mg was negatively correlated with LDL, while Zn, Fe and Zn / Cu were positively correlated with age. Tip stroke and Cu. Ca is lower and Zn, Pe, Mg are closely related.
