Inclusion Criteria:

1. Patients must have an age range between 18 to 65 years (inclusive).
2. Patients with fatty liver confirmed by ultrasound.
3. Patients must meet the criteria for impaired glucose regulation or type 2 diabetes mellitus (FPG ≥ 5.6 mmol/L and/or a two hour glucose value ≥ 7.8 mmol/L).
4. Course of diabetic mellitus no more than 1 years
5. Diabetic patients have not received anti-diabetic drugs, including insulin, biguanides, sulfonylureas, thiazolidinediones, Alpha-glucosidase inhibitors, or glinides for 4 weeks before the time of enrollment
