Methods: After the sorting and analysis of data in the physical examination of 4640 cases, the comparisons between the BMI and blood lipid, the levels of blood sugar and hematuria acid were compared in the groups according to sex and age. The levels of blood lipid, blood sugar and hematuria acid were compared in the fatty and nonfatty groups according to BWI. The levels of blood lipid, blood sugar and hematuria acid were also compared in the two groups according to sex and BWI.

对4640例体检者检查资料进行整理分析，按性别、年龄分组，比较体重指数与血脂、血糖和血尿酸的水平；按BMI分为肥胖组和非肥胖组，比较两组之间血脂、血糖和血尿酸的水平；进一步按性别和BMI比较两组之间血脂、血糖和血尿酸的水平。

The results were as follows the change of vitamin C content was a "trial apex"-shape curve, higher in young fruit,incrustation and maturation stages, lower in other periods; the total acid content was the highest in young fruit, after that, it decreased rapidly, maintained lower level, and reached lowest when the fruit matured; the total content of soluble sugar inosculated with the fruit development, it was high when the fruit development was quick, and low when the fruit development was slow; before 59 d after anthesis, the reducing sugar content was high in the total content of soluble sugar and after that ,the nonreducing sugar content was high; before 45 d after anthesis, free amino acid content was obviously correlated with protein content, and they inosculated with the fruit development;4559 d after anthesis, free amino acid content increased quickly, and protein content decreased gradually, this was also the most shaping period of the embryo and endosperm.

结果表明，Vc含量呈&三峰&型曲线，幼果时、硬核后和成熟时较高，其他时期较低；有机酸含量以幼果期最高，以后迅速下降并维持较低水平，果实成熟时含量最低；可溶性总糖含量与果实发育状况基本相吻合，果实发育速度快时含量较高，慢时较低；在谢花后59 d以前，可溶性糖以还原糖为主，之后以非还原糖为主；游离氨基酸和蛋白质含量，在谢花后45 d以前两者呈高度相关，且与果实生长速度相吻合，谢花后4559 d是胚和胚乳的主要形成期，此期游离氨基酸含量迅速增加，蛋白质含量持续下降。西北林学院学报21卷第5期张传来等金光杏梅果实发育期间主要营养成分动态变化研究
