Effect of Jiangtang Bushen Recipe (降糖补肾方) in Intervention Treatment of Patients with Impaired Glucose Tolerance

Objective:To evaluate the intervention effect of diet, exercise and Jiangtang Bushen Recipe (JBR, 降糖补肾方), a Chinese herbal recipe, in preventing the progress of patients with impaired glucose tolerance ( IGT ) to diabetes mellitus (DM) type 2. Methods: Fifty-one IGT patients with their diagnosis conformed to the diagnosis standard of WHO, 1999, were randomly divided into the control group (n = 26) and the TCM group (n=25). Patients in the control group attended to the educational course for DM and received dietotherapy and kinetotherapy, and to those in the TCM group, under these treatments, JBR was given additionally. Oral glucose tolerance test (OGTT), body weight index (BWI), levels of blood lipids and fasting insulin of all the patients were examined after 3 months, 6 months and 12 months of treatment. The total observation time was 1 year. Results:Except the 6 cases out of the 51 patients (11.7%), on whom the observa-tion discontinued, in the control group, as compared with before treatment, levels of fasting insulin and fasting blood glucose after treatment were not changed significantly ( P > 0. 05 ) , also insignificant difference was shown in levels of total cholesterol (TC) and triglyceride (TG), thoughthe two indexes lowered slightly after treatment (P>0. 05), but significant difference was shown in comparison of OGTT/2h, blood glucose and BWI (P<0. 05). While in the TCM group, fasting blood glucose was changed insignificantly (P> 0. 05) , but there was significant difference in comparison of fasting insulin, TC, BWI, OGTT/2h and plasma glucose levels (P<0. 01) respectively before and after treatment. At the end of the stud-y, the cumulative cases with conversion to diabetes were 3 (13. 6%) in the control group, and 1 (4. 3%) in the TCM group, x2 test showed insignificant difference in comparison of diabetes conversion rate between the two groups (P>0. 05), however, the TCM group showed a better year conversion rate of normal glucose tolerance than that in the control group (x2 = 8. 31, P<0. 01). Conclusion: TCM intervention is possibly effective in delaying the conversion of IGT to DM type 2, and plays integrative effeciency in impelling IGT patients to health. The favorable education and treatment of DM controlling, including dieto- and kineto-therapy may also be advantageous in IGT intervention, but could not be effective in blocking the advance of IGT.Original article on CJITWM (Chin) 2004 ;24 (4): 317
