目的分析肺炎支原体抗体阳性的儿童锌和维生素D含量。方法分别用酶联免疫法检测肺炎支原体抗体(MP),原子吸收光谱法检测锌含量,电化学发光免疫分析法检测25-羟基维生素D含量,用u检验统计分析阳性组与对照组的锌、25-羟基维生素D含量,用χ2检验统计分析两组的锌和维生素D缺乏率的差异。结果对照组锌和25-羟基维生素D含量分别为(75.33±16.03)μmol/L、(27.08±13.76)ng/ml,缺乏率为17.85%、8.57%;阳性组锌和25-羟基维生素D含量分别为(65.06±17.11)μmol/L、(26.64±12.82)ng/ml,缺乏率为35.71%、15.71%,两组的锌含量(u=5.185,P<0.05)和缺乏率都有显著差异(χ2=11.38,P<0.05),25-羟基维生素D含量(u=0.276,P>0.05)和缺乏率无差异(χ2=3.35,P>0.05)。结论肺炎支原体抗体阳性患儿及时补充锌对提高疗效、缩短病程有重要意义。
Objective To analyze the contents of zinc and vitamin D in children with Mycoplasma pneumoniae antibody positive. Methods Mycoplasma pneumoniae antibody (MP) was detected by enzyme-linked immunosorbent assay (ELISA), zinc content by atomic absorption spectrometry, 25-hydroxyvitamin D by electrochemiluminescence immunoassay. U test was used to analyze the contents of zinc, 25-hydroxy vitamin D content, χ2 test statistical analysis of the two groups of zinc and vitamin D deficiency rate differences. Results The contents of zinc and 25-hydroxyvitamin D in the control group were (75.33 ± 16.03) μmol / L and (27.08 ± 13.76) ng / ml respectively, with the rates of deficiency being 17.85% and 8.57% (65.06 ± 17.11) μmol / L and (26.64 ± 12.82) ng / ml respectively, the rate of deficiency was 35.71% and 15.71% respectively. There was significant difference between the two groups (u = 5.185, P <0.05) (χ2 = 11.38, P <0.05), 25-hydroxy vitamin D content (u = 0.276, P> 0.05) and no difference between the two groups (χ2 = 3.35, P> 0.05). Conclusion Mycoplasma pneumoniae antibody positive children with zinc supplementation in time to improve the efficacy and shorten the course of the course of great significance.
