摘要
目的探讨母婴因素对脐带血有核细胞总数(total nucleated cell,TNC)和CD34^(+)细胞数量的预测意义。方法对山东省脐带血造血干细胞库8267份公共库脐带血的产妇年龄、孕周、脐血体积、分娩方式、新生儿性别、血型等信息进行统计,以Spearman秩相关性分析为基础,结合多元线性回归分析研究了不同母婴因素对TNC、CD34^(+)细胞数量的影响。结果产妇年龄、新生儿血型与TNC和CD34^(+)细胞数量均无显著相关性;孕周、脐血体积、分娩方式、新生儿性别与TNC和CD34^(+)细胞数量均具有显著相关性,其中,分娩方式对TNC的影响最大,顺产的TNC高于剖宫产;新生儿性别对CD34^(+)细胞数量的影响最大,男孩脐血中的CD34^(+)细胞数量要高于女孩。结论通过分析母婴因素对脐血质量参数的影响和多元线性回归模型的建立,可有效预测脐带血中TNC和CD34^(+)细胞的数量。
Objective To explore the predictive significance of maternal and infant factors on the total number of nucleated cells(TNC)and CD34^(+)cells in umbilical cord blood.Methods Conducting statistical analysis on the maternal age,the gestational age,the volume of umbilical cord blood,the delivery method,the gender and the blood type of neonates,and other information of the 8267 samples collected from the Shandong cord blood hematopoietic stem cell bank.The effects of different maternal and infant factors on the number of TNC and CD34^(+)cells were studied,based on Spearman rank correlation analysis,combined with multiple linear regression.Results There was no significant correlation between the maternal age,the blood type of neonates and the quantity of TNC and CD34^(+)cells.The gender of neonates,the mode of delivery,the gestational age,and the volume of the cord blood were all significantly correlated with the quantity of TNC and CD34^(+)cells.The mode of delivery had the greatest effect on TNC,and the TNC of normal delivery is greater than that of cesarean section.The gender of neonates had the greatest effect on CD34^(+)cells,and the quantity of CD34^(+)cells in boys was bigger than in girls.Conclusion By analyzing the influence of maternal and infant factors on cord blood quality parameters and establishing a multiple linear regression model,the number of TNC and CD34^(+)cells in cord blood can be effectively predicted.
