Diabetes nephropathy (DN) is one of the most serious microvascular complications of diabetes, and also an important cause of death and disability of diabetes patients. There is no specific clinical staging of type 2 diabetes nephropathy at home and abroad, and there is no comprehensive study to comprehensively describe the occurrence and development of type 2 diabetes nephropathy through sensitive biomarkers, microvascular disease imaging and functional detection, digital markers and other multi-dimensional diagnosis and evaluation methods. Therefore, our research aims to establish a long-term follow-up queue for the whole cycle of diabetes nephropathy, develop multi-dimensional diagnostic and progress digital markers for diabetes nephropathy, develop a multimodal non-invasive diagnostic model and a new clinical staging/typing, and create a multi-dimensional accurate diagnosis and treatment system for type 2 diabetes nephropathy combining traditional Chinese and western medicine.
