【摘要】 目的:揭示中国老年女性血红蛋白参考值的地理分布规律,为制定其统一标准提供科学依据。方法:收集中国157个地区用氰化高铁血红蛋白(HiCN)法测定的15690例血红蛋白参考值,运用因子分析、GIS空间分析和相关分析的方法研究其与地理环境之间的复杂关系特征及其分布规律。结果:用因子分析将5个地理环境的因素综合成2个公共因子F1和F2,用其得分值代替原始数据推导出回归方程:^y=127.9-0.01009F1-0.01543F2±8.8。用该方程计算出中国1288个观测点的参考值,借助GIS软件下的空间分析模块精确的内插出中国老年女性血红蛋白正常参考值的分布规律,其呈现出西高东低、北高南低的分布规律。结论:若已知中国某地的海拔高度(X1)、年日照时数(X2)、年平均相对湿度(X3)、年平均气温(X4)和年降水量(X5),可用该方程计算出该地区血红蛋白参考值,从趋势分布规律图也可得出中国任何地方的血红蛋白参考值。更多还原

【Abstract】 Objective To reveal the geographical distribution regularity of the normal reference value of old female’s hemoglobin in China,and provide scientific basis for making its unified standards.Methods The normal reference values of 15 690 examples of old female’s hematocrit by the method of hemoglobin cyanide(HiCN)and five geographical factors in 157 areas in China,its distribution regularity and the complex relationship characteristic between geography environment elements were analyzed with the methods of factor analysis,spatial analysis of GIS and correlation analysis.Results By the method of factor analysis,the five factors of geography environment were combined into two common factors F1and F2;the original data was replaced with its scores to infer the regression equation :y^=127.9-0.01009F1-0.01543F2±8.8.And this equation was used to figure out the reference value of 1 288 observation points in China.With support of the model of spatial analysis of GIS,the distribution regulation of old female’s hemoglobin reference value in China and its distribution regularity was west-higher,east-lower,north-higher and south-lower.Conclusion If some area’s altitude(X1),sunshine hours yearly(X2),mean relative humidity yearly(X3),mean temperature yearly(X4),precipitation yearly(X5) are known,this place’s reference value of hemoglobin can be calculated out by using this equation.The reference value of hemoglobin in any areas in China can be gotten from the trend distribution regularity map.更多还原
