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.
