Screening and Application Research of Early Diabetic Nephropathy Markers Based on Lipidomics.

The present study was a scientific research project concurrently conducted by clinical and laboratory. In term of clinical research, the basic personal data, medical history, physical examination and auxiliary examination results of subjects were mainly recorded. Whereas in term of basic research, the serum, plasma and urine samples of patients were collected for serological and metabonomics research to find new biomarkers. First, we recruited the patients who met the inclusion criteria. The patients' serum, plasma and urine were collected at baseline after obtaining informed patient consent. Simultaneously, the basic information, anthropometric indicators (including height, weight, waist circumference, hip circumference, blood pressure), past history, family history, menstrual history, birth history, medication history, lifestyle of the patients were registered, and the corresponding laboratory examination and auxiliary examination were carried out according to the diagnostic process. All data and data were entered into the database for later analysis. After the initial diagnosis, the patients were enrolled in the current trial. The patients were followed up annually until the last follow-up visit, and the complete follow-up was conducted for at least 5 years. Each follow-up followed the principles of routine clinical diagnosis and treatment. In addition, the patients' serum, plasma and urine samples were collected once a year during follow-up, and a centralized test of glycosylated hemoglobin was performed once a year. In this study, the pathogenesis of type 2 diabetic nephropathy was explored through multi-center standardized clinical follow-up; The potential mechanism and possible biomarkers in patients with early renal diseases of type 2 diabetes was explored through prospective long-term follow-up, so as to find novel therapeutic approaches and suitable population.
