Umbilical cord blood is not useful for treating nephritis. Umbilical cord blood contains hematopoietic stem cells, which can replace the cells of one’s own malignant lesions, so it can be used to treat some hematologic diseases, such as leukemia. The treatment of nephritis needs to be determined according to the pathological results, as well as the amount of quantitative urine protein and renal function. If it is a mild nephritis, such as urine protein quantification of less than 3.5 grams / day, kidney function is normal, then only need to apply ACEI or ARB drugs, such as timosartan, valsartan, perindopril, etc. to reduce urinary protein and protect the kidneys. If the quantitative amount of urinary protein is too large or the renal function is abnormal, renal puncture biopsy is needed, and according to the pathological results, glucocorticoid as well as immunosuppressant treatment may be added.
