- Brief Summary
The purpose of this study is to evaluate Effect of Fasting Therapy on Blood Glucose Control and Islet Function in Newly Diagnosed Type 2 Diabetic Patients.
- Detailed Description
This study was to investigate the effects of fasting therapy on blood glucose control and islet function in newly diagnosed type 2 diabetic patients.
60 participants will be recruited from outpatients or inpatients in First Affiliated Hospital of Sun Yat-sen University according the eligibility criteria. All the eligible subjects will be randomly allocated into 2 groups, the fasting group and the intense insulin therapy group. The former one will receive fasting therapy for 14 days and the latter be treated with an intense insulin therapy including short-term continuous subcutaneous insulin infusion treatment or four stage intensive insulin treatment for 2 weeks.
First of all, to determine whether fasting therapy is effective for glucose control or not, the investigators will observed the required time and control rate for a targeted glucose level, the average fasting blood glucose and postprandial blood glucose as well as the glucose amelioration degree in all the patients. Then, all the patients will undergo a follow-up period of 1 year, during which the fasting and postprandial blood glucose and glycosylated hemoglobin of each participant will be monitored to assess the long-term remission rate of diabetes. Patients are invited to review their glucose and lipid metabolic indices at 3 months, 6 months and 12 months of follow-up. Lifestyle guidance will be offered by specialist physicians throughout the follow-up period.
Secondly, all the patients are required to take the insulin and C-peptide releasing tests before and after fasting as well as in the follow-up to investigate the short-term and long-term treatment effect of islet function through accessing the first secretion function of pancreatic island and calculating insulin resistance(HOMA-IR) and HOMA-B through homeostasis model assessment.
In summary, this study aims to explore the short-term and long-term therapeutic effects in new onset type 2 diabetes, hoping to provide a novel, effective and more convenient treatment method for them.

Group Intervention Description Fasting therapy Fasting therapy Fasting therapy, lasting for 14 days, all subjects are isolated from ordinary food. However, drinking water is not limited and they are encouraged to drink more, at least 3 liters. Besides, they need to take some middle intensity exercise for at least 2 hours. They will take some prescribed medications except for hypoglycemic drugs. Fasting therapy Exercise Fasting therapy, lasting for 14 days, all subjects are isolated from ordinary food.

- Primary Outcome Measures
Name Time Method The remission rate of diabetes 6 months
- Secondary Outcome Measures
Name Time Method β-cell function--HOMA-B (%) 6 months HOMA means "Homeostasis model assessment". It is a designed model for evaluating the extent of individual's insulin resistance. The specific calculate formula is listed as follows, "fasting plasma glucose(mmol/l) × fasting insulin(mIU/L)/22.5". So it's a specific value without measurement. The normal value of it is 1. Higher than 1 indicate insulin resistance. HOMA-B refers to the basial pancreas islet function. The formula is "20 × fasting insulin / (fasting plasma glucose-3.5)". The measurement of it is percent(%). The normal value of it is 100%. The value of it will decrease when the patients's pancreas islet function is worse.
