2h与24h尿钙/肌酐比值的相关性分析

Correlative analysis of 2 hours and 24 hours urinary ca/cr ratios

目的 了解晨起 2h尿Ca/Cr和 2 4h尿Ca/Cr的相关性。方法 对 3 2例甲亢病人和 3 0例Ⅱ型糖尿病病人进行同日晨起 2h和 2 4h尿Ca/Cr比值测定 ,分析两个时段尿Ca/Cr比值的相关性。结果 两种病患者的 2h尿Ca/Cr比值与 2 4h尿Ca/Cr比值均高度相关 (甲亢 :r=0 .844,p<0 .0 1;糖尿病 :r=0 .75 5 ,p <0 .0 1)。结论 晨起 2h尿Ca/Cr和 2 4h尿Ca/Cr比值高度相关 ,临床上可用 2h尿Ca/Cr比值代替 2 4h尿Ca/Cr比值。

Objective To study the correlation between 2 h in the early morning and 24 h urinary Ca/Cr ratios. Methods 2 h urinary Ca/Cr ratio in the early morning and that of 24 h were compared and treated statistically in 32 hyperthyroidisms and 30 type-2 diabetes. Results 2 h urinary Ca/Cr in the early morning was closely correlated with 24 h urinary Ca/Cr (hyperthyroidism group: r =0.844, P <0.01; type-2 diabetic group: r =0.755, P <0.01). Conclusion 2 h urinary Ca/Cr ratio might replace the 24 h urinary Ca/Cr ratio in clinical hyperthyroidisms or type-2 diabetes.
