广西贺州市孕妇全血微量元素检测结果探讨

目的：探索广西贺州市孕妇和健康妇女全血微量元素含量水平，为合理补充微量元素提供参考依据。方法：将968例来自广西贺州市人民医院孕妇按孕周分为早孕组186例，中孕组730例和晚孕组52例，采用原子吸收分光光度法检测早孕组、中孕组、晚孕组及86例来自广西贺州市人民医院正常对照组妇女全血中的微量元素铜、锌、钙、镁、铁的含量，比较4组检测值。结果：早、中、晚孕组与对照组相比，铜随孕期增加而增加，差异有统计学意义（P〈0．01），但早、中、晚孕3组间差异无统计学意义（P〉0．05）；全血锌、钙在早、中孕期随孕周的增加其含量不断降低，与对照组比较，差异有统计学意义（P〈0．05），但早、中、晚孕3组比较无明显差异（P〉0．05）；全血镁、铁随孕周的增加其含量不断降低，早、中、晚孕期检测结果与对照组比较均有差异（P〈0．05）；其中铁元素早、中、晚孕组均缺乏明显（P〈0．01）。结论：广西贺州市孕妇应该根据自身情况适当补充微量元素。

ANALYSIS OF BLOOD TRACE ELEMENTS OF PREGNANT WOMEN IN HEZHOU

Objective.To compare the levels of serum trace elements between pregnancy women and healthy women in Hezhou, and provide the reference for the replenishment of trace elements. Methods： A total of 968 cases of pregnancy women were divided into three groups according to pregnancy weeks, early pregnan- cy （〈16 weeks, n =186）, middle pregnancy （16 to 28 weeks, n =730）, and late pregnancy （〉28 weeks, n =52）. Serum trace elements in three groups and a normal group （ n =86） were detected by atomic ab- sorption spectrophotometry. Results. As compared with control group, serum copper in group pregnancy increased significantly with the time of pregnancy （ P 〈0.01）, while serum magnesium and iron reduced significantly （ P 〈0.05）. Serum zinc and calcium in groups early pregnancy and middle pregnancy reduced significantly with the time of pregnancy （ P 〈0.05）. Serum iron in groups middle pregnancy and late preg- nancy reduced significantly than those in group early pregnancy with the time of pregnancy （ P 〈0.05）. Conclusion： Pregnancy women should be supplied with trace elements.
