目的 通过对500例儿童血样的5种元素进行检测,评价儿童血中微量元素的水平.方法 对500例儿童血样采用BH-5100五通道原子吸收光谱仪检测血锌、铁、钙、铜和镁的含量,并进行统计分析.结果 500例儿童血样中5种微量元素普遍缺乏,其中铁缺乏严重,占65.8%;其他缺乏的元素依次分别为:锌(44.4%)、钙(27.0%)、铜(16.4%)、镁(12.6%).铁缺乏率在不同的年龄组之间比较有极显著性差异(χ2=14.12,P<0.01),其他微量元素的缺乏率在不同年龄组中无显著性差异(均P>0.05).结论 乌鲁木齐市儿童铁缺乏严重,在临床诊断和治疗中应予以重视.%Objective To assess the blood microelement level by detecting 5 kinds of microelements in blood samples of 500 children. Methods The contents of zinc, iron, calcium, copper and magnesium in 500 blood samples were detected with BH-5100 five-channel atomic absorption spectrophotometer, and the results were analyzed. Results All of 5 kinds of microelements were deficient in 500 cases, and iron deficiency was highest, occupying 65. 8% . The other deficient microelements were zinc ( 44. 4% ), calcium ( 27. 0% ), copper ( 16.4% ) and magnesium ( 12.6% ) in order. There was significant difference in iron between different groups (χ2 = 14. 12,P <0.01 ), but no difference was found in other four microelements among different groups ( all P >0. 05 ). Conclusion Iron deficiency is common in children in Urumqi city, so special attention should be paid in the course of diagnosis and therapy.
