Impaired Glucose Tolerance
Conditions
Brief summary
Impaired Glucose Tolerance (IGT) is an abnormal metabolic state following glucose metabolic steady state but prior to diabetes. IGT is an important stage during the progression of diabetes, with an underlying mechanism of insulin resistance and pancreatic β cell dysfunction. IGT is one of the diseases that shows significant beneficial response to acupuncture treatment. Original findings from the investigators'laboratory show that transcutaneous auricular vagus nerve stimulation (taVNS) which is innervated by vagus nerve, would enhance the activity of pancreatic β cells, promote the secretion of insulin, upregulate the expression of insulin receptors in central as well as peripheral tissues, thus to improve glycometabolism. In this study, the investigators would further illuminate the mechanism of taVNS at yidan-pi auricular acupoints on the regulation of glucose metabolism, its improvement of the IGT state in rat model, as well as its regulation effect on insulin receptor expression and insulin resistance, and systematically illustrate the clinical effective of this treatment on IGT, with emphasize on its influence on the concentrations of glucose and HbA1c, and thus provide an effective proposal for clinical acupuncture.
Interventions
DEVICEta-VNS
The transcutaneous vagus nerve stimulation (taVNS) at auricular concha is a typical representative of TCM modernization. The taVNS regulates the autonomic nervous system, which shows a good therapeutic effect for the treatment of IGT.
OTHERElectro-acupuncture
one of the most common acupuncture methods, selecting acupoints based on traditional Chinese medicine theory. It exerts the function to regulate qi and blood circulation and balance Yang and Yin energy inside body.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| FPG | Baseline and 6 week, 12 weeks | The fasting plasma glucose (FPG) is used to diagnose diabetes. IGT can be diagnosed base on FPG less than 7.0 mmol/L. |
| OGGT | Baseline and 6 week, 12 weeks | The 2-hour plasma glucose after a 75-g oral glucose tolerance test (OGTT) is used to diagnose diabetes. IGT can be diagnosed base on 2-hour plasma Glucose between 7.8 and 11.1 mmol/L. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| BMI | Baseline and 12 weeks | The body mass index are used to diagnose Obesity. Weight and height will be combined to report BMI in kg/m\^2 |
| A1C | Baseline and 6 week,baseline and 12 weeks | The hemoglobin A1C (A1C) is a diagnostic test for diabetes. Diabetes can be diagnosed base on A1C more than 6.5%. |
Other
| Measure | Time frame | Description |
|---|---|---|
| pulse | Baseline and 12 weeks | Normal pulse should be more than 60 per minute, or less than 100 per minute. |
| respiration | Baseline and 12 weeks | Normal respiration should be more than 16 times, or less than 20 times. |
| blood pressure | Baseline and 12 weeks | The systolic pressure should be no more than 139 mmHG, and the diastolic pressure should be no less than 89 mmHg. |
| body temperature | Baseline and 12 weeks | Normal temperature should be more than 36 C, or less than 37 C. |
