Objectives of Study:

Verify the intervention effect of GQ formula granules on damp-heat type 2 DKD and comprehensively evaluate its safety. Compare the efficacy differences between GQ formula granules and traditional decoctions in the treatment of damp-heat type 2 DKD. Evaluate whether the efficacy of GQ formula granules in treating damp-heat type 2 DKD shows a dose-effect relationship and provide a scientific basis for determining the optimal therapeutic dose.

Randomization Procedure (please state who generates the random number sequence and by what method):

The stratified block randomization method is adopted. Stratification is carried out according to centers. With the help of SAS statistical software and a given seed number the Center Coding Random Number Table is generated. Firstly it is randomly divided into the GQ decoction group (group D) and the formula granule group (the ratio of the two groups is 1:3). Then the three groups in the GQ formula granule group are randomly grouped again. The conventional dose formula granule group (group M): low-dose formula granule group (group L): formula granule simulator group (group P) is 1:1:1. Subjects are enrolled according to random numbers. If the patient meets the enrollment conditions the researcher logs in to the randomization system and enters the user name and password (the user name and password are uniformly distributed to each center by the system administrator). After entering the system input patient-related information (such as name date of birth gender etc.) and the system automatically generates a random number.
