RESUMEN
Diabetic nephropathy （DN） is one of the common chronic kidney diseases （CKD） worldwide and a major cause of end-stage renal disease （ESRD）， seriously threatening and affecting the life and health of the global population. Currently， the pathogenesis of DN is considered to be closely related to factors such as glucose metabolism disorders， abnormal lipid metabolism， oxidative stress， activation of inflammatory factors， autophagy， and cell apoptosis in the continuous high-glucose environment of the body. Renal fibrosis is an important pathological feature and ultimate pathological outcome of DN. Timely intervention in renal fibrosis is of significant clinical and practical importance for the prevention and treatment of DN. Due to the limitations of western medicine in treating DN， traditional Chinese medicine （TCM） intervention in the process of renal fibrosis in DN has been widely used as a routine and potential treatment method due to its multi-component， multi-effect， and multi-target effects， effectively delaying the progression of the disease. It has been found that the Notch signaling pathway plays an important role in the development and maintenance of homeostasis in the body， and abnormal activation of the Notch signaling pathway is associated with DN. Activation of this signaling pathway plays a key role in the process of renal fibrosis. This article reviewed the regulatory mechanism of the Notch signaling pathway in renal fibrosis in DN， focusing on the relationship between targeting Notch signaling pathway by Chinese medicinal monomers and prescriptions and renal fibrosis in DN in order to provide a theoretical basis for the development of new drugs， basic research， and clinical application of TCM in the prevention and treatment of DN.
