With the help of the 'Traditional Chinese Medicine Specialty Alliance Platform-Multicenter RCT Clinical Research Database,' this platform can be used to conduct scientific research on various aspects of DKD, such as disease prediction, treatment effectiveness evaluation, and recurrence rate analysis, providing effective means to improve DKD remission rates, delay disease progression, and enhance patients' quality of life. By selecting the Jiade Yishen Xiaozheng Qufang formula and conducting multicenter, prospective, double-blind RCT studies, its clinical value in improving DKD remission rates can be verified. With the support of scientific research, DKD treatment strategies can be optimized, therapeutic efficacy improved, recurrence rates reduced, and disease progression delayed, thereby enhancing patients' quality of life.

Cooperative units jointly carry out a prospective randomized placebo-controlled parallel double-blind study, relying on a multi-center clinical research platform, and verify through multi-center, prospective, double-blind RCT studies the clinical value of the Jia Jian Yi Shen Xiao Zheng Qu Feng Formula in improving the remission rate of DKD, in order to optimize the treatment strategy for DKD.
