Objective :To measure the content of 25-(OH)D3(25-hydroxylase catalytic system generated ossification diol) in the blood serum of the children of different ages, and to probe into the relativity of 25-(OH)D3 with BAKP(bone alkaline phosphatase) and trace elements.
Methods: Totally 382 cases of children were chosen, who took routine physical examination in the health care center of our hospital, as the research object.Divide the children into 5 groups according to their different ages:≤1,>1~3,>3~5,>5~7 and >7~12. Detect the concentration of serum 25-(OH)D3, the serum BAKP and some trace elements, such as the Cu,Zn,Fe and Mg by using enzyme-linked immune testing method.
Results: Children of all ages were obviously in lack of 25-(OH)D3.By using the Pearson correlation analysis, it was shown that the relativity between Zn and BAKP,Cu,between Fe and BAKP,Cu,Zn,between Mg and Cu,Z,Fe was very obvious(P<0.05).There was relativity between 25-(OH)D3 and BAKP(P<0.05).But there was no obvious relativity between 25-(OH)D3 and trace elements such as Cu,Zn,Fe and Mg(P>0.05).
Conclusion: Children of 0~12 years old have different degree of 25-(OH)D3 deficiency, which is especially serious in the children of 0~3 years old.The relativity analysis shows that there is connection between 25-(OH)D3 and BAKP, but there is no connection between 25-(OH)D3 and such trace elements as Cu,Zn,Fe and Mg.Taking Zn and Fe can help improve the BAKP content,which is very beneficial to children′s health.
