The diet of patients was adjusted with fixed volume of staple food depending on the degree of labor and constitution. Other hypoglycemic agents were forbidden in the observation period. The control group was treated only by diet controlling. Clinical symptoms, signs, Urinary glucose of patients were observed and 24 hours quantitative test of urinary glucose, saccharified hemoglobin and serum insulin were treated before and after the treatment.
　　
Result: Referring to the efficacy evaluation Standard in "Guidance on Principle of Clinical Research" promulgated by National Ministry of Health, therapeutic effect on the patient whose symptoms disappeared and fasting blood sugar reduced to normal range is taken as markedly effective; on those symptoms disappeared basically or alleviated obviously, fasting blood sugar lowered to below 8.33 mmol/L, urinary glucose lowed to (+) or (++) is taken as improved; on those Who is not arrived the above-mentioned norms is taken as ineffective. In the treatment group, the effect was assayed as markedly effective in 32 cases, 64%; as improved in l4.28% and as ineffective in 4.8%, the total effective rate 92%. In the control group, 4 (l3.3%) was markedly effective, 6 (20%) improved, 20 (66.7%) ineffective, and the total effective rate being 33.3%. The comparison between the two groups showed significant difference (P<0.0l). The fasting blood sugar 24 hours urinary glucose and sascharified hemoglobin in both groups were reduced and serum insulin increased, but as compared with the results in the control group, these criteria in the treatment group were improved more favourable, P<0.0l.

Conclusion: YZHD has satisfactory therapeutic effect in treating diabetes mellitus.
