120例肺炎患儿血清营养素水平分析

Analysis of nutrient elements of 120 infants with pneumonia

目的探讨肺炎患儿体内血清营养素水平的变化。方法应用高效液相色谱法、原子吸收光谱法和酶联免疫法等,对120例肺炎患儿(肺炎组)的血清锌、铁、镁、钙、维生素A、维生素D等指标进行检测,同期随机抽取60例健康同龄儿(对照组)作为对照。结果肺炎组铁、锌、维生素A缺乏率及含量均低于对照组(P<0.05),钙、镁、维生素D缺乏率及含量比较差异无统计学意义(P>0.05)。结论肺炎患儿的锌、铁、维生素A缺乏普遍存在,在调节和介导免疫发应的过程中有一定作用。

Objective To explore the levels of certain vitamins and trace elements in infants with pneumonia.Methods Serum levels of zinc,calcium,magnesium,iron,vitamin A and vitamin D were detected with HPLC in 120 infants with pneumonia（group A） and 60 healthy controls（group B）.Results The deficiency rates of iron,zinc and vitamin A were significantly higher in group A than those in group B（P〈0.05）.Serum levels of calcium,magnesium and vitamin D were not significantly different between two groups（P〈0.05）.Conclusion The deficiency of zinc,iron and vitamin A is common in infants with pneumonia,which may play a role in regulating and meadiating immune function.
