目的:探讨母血与脐血血清维生素正常水平值及相互关系。方法:对2002年1月～2003年6月在天坛医院妇产科进行检查的北京市崇文区540例孕产妇配对测定母血、脐血中维生素A、C、D、E浓度,比较其水平并进行相关性分析。结果:脐血与母血比较,维生素A、C、D、E差异有显著性意义,脐血维生素值普遍低于母血。母血与脐血维生素A、C、D、E具有相关性。其中尤以母血维生素A与脐血的相关性大。结论:本次研究测得母血、脐血维生素值均低于正常值。提示孕期应合理补充维生素,定期检测体内维生素的含量,母血与脐血维生素A、C、D、E含量具有相关性,妊娠期补充维生素对提高新生儿体内维生素含量有作用,以提高维生素A最容易见效。
Objective: To investigate the relationship between serum vitamin levels in maternal and umbilical cord blood and their normal levels. Methods: From January 2002 to June 2003, maternal and umbilical blood samples were collected from 540 pregnant women in Chongwen District of Beijing Municipality for examination of obstetrics and gynecology in Tiantan Hospital. The concentrations of vitamin A, C, D and E were measured and compared with each other And correlation analysis. Results: Compared with maternal blood, the differences of vitamin A, C, D and E in umbilical cord blood and maternal blood were significant, and the vitamin value in umbilical cord blood was lower than maternal blood. Maternal blood and cord blood vitamin A, C, D, E has relevance. Especially in maternal blood vitamin A and cord blood related. Conclusion: This study measured maternal blood, umbilical cord blood vitamin values were lower than normal. Prompt pregnancy should be a reasonable vitamin supplements, regular testing of vitamin content in the body, maternal blood and umbilical cord blood vitamin A, C, D, E content is related to pregnancy vitamin supplements to improve neonatal body vitamin content in order to improve vitamin A The most effective.
