The invention relates to a weight loss intervention method and device for chronic renal failure and obesity patients based on an individualized prescription. The method comprises the following steps: constructing a multi-modal dynamic time sequence feature vector of a patient; identifying and quantifying potential causal effects of different weight loss intervention measures on physiological outcomes of renal functions, electrolyte balance, anemia states, bone mineral metabolism and weight indexes of the CKD patient according to a dual robust estimator; dynamically constructing a weight loss intervention measure causal model according to the potential causal effect of the physiological outcome of each patient and the physiological and pathological background; and inputting the multi-modal dynamic time sequence feature vector of the patient into a weight loss intervention measure causal model, and generating a daily diet scheme, an exercise scheme and corresponding high-confidence risk early warning and causal explanation of the patient. The method overcomes the limitation that the traditional method only pays attention to correlation and cannot clearly determine the intervention effect, ensures that the causal atlas and the intervention scheme are optimized according to the real-time change state of the patient, and realizes a real dynamic prescription.

The mechanisms driving the development of extracapillary lesions in focal segmental glomerulosclerosis (FSGS) and crescentic glomerulonephritis (CGN) remain poorly understood. A key question is how parietal epithelial cells (PECs) invade glomerular capillaries, thereby promoting injury and kidney failure. Here the inventors show that expression of the tetraspanin CD9 increases markedly in PECs in mouse models of CGN and FSGS, and in kidneys from individuals diagnosed with these diseases. Cd9 gene targeting in PECs prevents glomerular damage in CGN and FSGS mouse models. Mechanistically, CD9 deficiency prevents the oriented migration of PECs into the glomerular tuft and their acquisition of CD44 and β1 integrin expression. These findings highlight a critical role for de novo expression of CD9 as a common pathogenic switch driving the PEC phenotype in CGN and FSGS, while offering a potential therapeutic avenue to treat these conditions. Accordingly, CD9 represents a reliable biomarker and as well as a biotargets in glomerulonephritides.

The application discloses a hemodialysis sufficiency evaluation method based on sodium balance, and relates to the technical field of hemodialysis, and the method comprises the following steps: obtaining the body weight, dry body weight and serum sodium concentration of a patient before dialysis; calculating a target sodium removal amount Na_target=DeltaW* [Na]s / 0.93, and establishing a quantitative equivalent relationship between the body weight increase and sodium accumulation; obtaining or calculating an actual sodium removal amount (including two ways of convection and diffusion); calculating a sodium removal ratio R_Na=Na_actual / Na_target; and evaluating the dialysis sufficiency according to the R_Na. The application firstly changes the dialysis sufficiency evaluation from 'urea removal' to'sodium and water removal', and directly aims at the main pathological burden of kidney failure patients, i.e. sodium and water retention. The sodium removal ratio R_Na is more directly related to the volume state and cardiovascular prognosis of the patient than the traditional Kt / V index. The method only needs the body weight and serum sodium before and after dialysis to be calculated, and can be integrated into the existing dialysis information system.
