Objective: Observation Liuwei Dihuang soft capsule treat diabetes (kidney Yin deficiency syndrome) clinical curative effect. Method :Two hundred and thirty-six cases by stratified area group diabetes patients randomized

double-blind simulation

positive drug and placebo parallel control

multicenter clinical test method. Test points three groups

4.75%more: 118 cases of

oral Liuwei Dihuang soft capsule (3 grain/times) + left to pill simulation medicine (9 g/times)

2 times per day

the morning 1 times; 0 case: oral group 1 ∶6 Liuwei Dihuang soft capsule simulation medicine (3 grain/times) + left to pill (9 g/times)

2 times per day

the morning 1 times; All cases of control group

oral Liuwei Dihuang soft capsule simulation medicine (3 grain/times) + left to pill simulation medicine (9 g/times)

2 times per day

the morning 1 times. All three groups of course of 8 weeks. Result :Three groups of patients after disease medication syndromes curative effect levels of comparative differences have statistically significant (P < 0.001). Blood sugar control efficacy effect similar

difference was statistically significant. After treatment

the most major clinical symptoms improved situation between three groups was statistically significant comparative differences. Three groups were some cases after treatment laboratory appears unusual clinically meaningful change

clinical doctors think'change and test drug is not a matter of. Conclusion :The three groups of patients after treatment efficacy of disease syndromes difference between the level of statistical significance (P<0.001); effect of glycemic control similar effect

the difference was not statistically significant; clinical symptoms after treatment

most of the major improvements in three differences between groups was statistically significant. Three groups after treatment in some cases laboratory tests are clinically significant abnormal changes in clinical doctors to determine 'change has nothing to do with the test drugs.
