Study Arms (3)

oral drugs

EXPERIMENTAL

oral anti-diabetic drugs only.metformin,start from 500mg bid,if blood glucose dose not reach the standard,added to 500mg tid→1000mg bid.if metformin reach the biggest dosage,added gliclazide modified release tablets,from 30mg qd,if blood glucose dose not reach the standard,add dosage 30mg qd→60 mg qd→90mg qd→120mg qd(max).if still not reach the target,add acarbose 50mg tid

Drug: Metformin

lantus

EXPERIMENTAL

basal insulin combine with oral drugs,started with insulin glargine 0.2 u/kg subcutaneous injection at 10pm(at 8am if patients are night workers),add dosage if glucose dose not reach the target.after that,you can add oral drugs ,as Group Oral Drugs.

Drug: Lantus

Novomix30

EXPERIMENTAL

premixed insulin combine with oral drugs,started with premixed insulin subcutaneous injection(0.4-0.6 u/kg divided into half before breakfast and dinner),and add dosage if glucose dose not reach the target.after that,you can add oral drugs ,as Group Oral Drugs .

Drug: Novomix30

Interventions

start with metformin,from 500mg bid,if metformin reach the biggest dosage,added gliclazide modified release tablets,afterthat,add acarbose

oral drugs
LantusDRUG

started with insulin glargine 0.2 u/kg subcutaneous injection ,add dosage if glucose dose not reach the target.after that,you can add oral drugs(like oral drug group)
