The invention relates to the technical field of
traditional Chinese medicine preparations, and particularly discloses a
traditional Chinese medicine composition for treating
diabetic nephropathy and application thereof. The
traditional Chinese medicine composition is prepared from the following ten medicinal materials according to a specific ratio: radix rehmanniae recen,
astragalus membranaceus, golden
cypress,
coptis chinensis,
gastrodia elata,
cicada slough,
salvia miltiorrhiza, chinaroot greenbrier,
rosa laevigata michx and
motherwort. Systematic animal experiments and clinical researches prove that the Zuogui blood-glucose-reducing
kidney-pleasing formula can effectively reduce fasting blood-glucose of
diabetic nephropathy model mice, improve
lipid metabolism disorder, remarkably reduce the levels of
urea nitrogen,
creatinine and
uric acid and the ratio of
urine protein to
creatinine, and can be used for treating
diabetic nephropathy by inhibiting expression of
fibrosis-
related factors such as TGF-beta and alpha-SMA. The
renal fibrosis process is delayed. Compared with the prior art, the pharmaceutical composition provided by the invention has remarkable advantages in the aspects of improving renal functions, inhibiting
renal tissue fibrosis and delaying the development of diabetic
nephropathy.
