Purpose
The investigators hypothesize that the chronic kidney disease patients who suffer from vitamin D deficiency will be benefit from given Vitamin D2 because coronary artery calcification and hyperparathyroidism will be improved.

Primary Outcome Measures:
- the improvement of coronary artery calcification [ Time Frame: 2 years ] [ Designated as safety issue: No ]We use CT to detect the coronary artery calcification score in the chronic kidney disease patients for 3 times (baseline, 12 month and 24 month). We will compare the 2 arms （treatment or not）to know if there is any difference。
Secondary Outcome Measures:
- the improvement of proteinuria [ Time Frame: 2 years ] [ Designated as safety issue: No ]We detect the microalbuminuria in the chronic kidney disease patients for 5 times (baseline, 6 month,12 month 18month and 24 month). We will compare the 2 arms （treatment or not）to know if there is any difference。

Drug: Vitamin D2
25（OH）D level <12 nmol/L 50000IU/weekX12week， 12-39 nmol/L 50000IU/weekX4week then，50000IU/month， 40-75 nmol/L 50000IU/month， 75-116.75nmol/L 25000IU/month， ＞116.75nmol/L stopped. Other Name: Vitmain D2 capsule

Detailed Description:
We will call for 350 CKD patients (250 CKD3-5stage and 100 CKD5D stage)who suffer from vitamin D deficiency.They will be divided into 2 groups. One group will be given vitamin D and the other will not. They will take coronary artery CT test every year(in 2 years).We will compare the coronary calcification progression between the 2 groups.
