对西宁市３５例分娩孕妇及其新生儿脐血进行了全血钙、镁、铁、锰含量的测定及相关分析。结果表明，母血钙、镁、铁３种元素低于脐血，差别有高度显著性（Ｐ＜０．０１）；镁、铁含量母血与脐血之间呈正相关（ｒ＝０．４２３，ｐ＜０．０５和ｒ＝０．５１６，ｐ＜０．０１），而钙和锰无相关（Ｐ＞０．０５）。母体在钙和铁量不足的情况下，仍要满足胎儿的需要。
The contents and contents of calcium, magnesium, iron and manganese in whole blood of 35 pregnant women and their newborns born in Xining City were measured and analyzed. The results showed that the three elements of maternal calcium, magnesium and iron were lower than umbilical cord blood, the difference was highly significant (P <0.01). There was a positive correlation between magnesium and iron content of maternal blood and umbilical cord blood (r = 0.423 , P <0.05 and r = 0.516, p <0.01), while there was no correlation between calcium and manganese (P> 0.05). Maternal calcium and iron in the case of insufficient, still have to meet the needs of the fetus.
