| ［摘要］ 慢性肾脏病（chronic kidney disease，CKD）患者常伴有营养性维生素D缺乏的情况，虽然活性维生素D已被广泛用于CKD的治疗，但普通维生素D的补充尚未得到足够关注。研究证实普通维生素D的补充区别于活性维生素D临床意义，充足的25(OH)D水平除了能给肾脏尚存的1α羟化酶提供足够的底物以外，还可促进肾外组织在局部产生更多的1,25(OH)2D，调节许多组织细胞的增殖和分化。因此，对CKD患者来说，除了补充活性维生素D外，普通维生素D的补充也值得重视。 |

| Abstract: |
| ［Abstract］ Patients with chronic kidney disease(CKD) are more prone to developing vitamin D deficiency. Although traditional therapies with active vitamin D or vitamin D analogues have been widely used in patients with CKD, nutritional vitamin D supplementation is not paid much attention. There is increasing evidence suggesting that supplementation with plain vitamin D has important clinical benefits distinguishing from active vitamin D. Adequate serum 25(OH)D not only provides renal 1 alpha hydroxylase with sufficient substrate, but also contributes to local production of 1, 25(OH)2D in the extra-renal tissues. Thus generating their own 1, 25(OH)2D from circulating 25(OH)D creates pleiotropic effects, including regulation of proliferation and differentiation of many cell types. Therefore, nutritional vitamin D supplementation should be paid sufficient attention in CKD patients with vitamin D deficiency. |
