The AU5800 fully automatic biochemical analyzer produced by Beckman Coulter Co., Ltd. was selected for renal function index determination. peripheral venous blood (3-5 mL) was extracted before and after treatment, and Cre and urea nitrogen were measured after centrifugation

According to the relevant contents of the Clinical Guiding Principles of New Chinese Medicine13, clinical symptoms of shortness of breath, fatigue, anorexia, chills, abdominal fullness and distension, unsolid stool, and weak waist were evaluated.

In patients, 3 mL of fasting venous blood was collected and given anticoagulant treatment. The total serum protein, serum albumin, hemoglobin, and total red blood cells were measured by Mindray automatic biochemical analyzer (model BS-280, Shenzhen Mindray Bio-Medical Electronics Co., LTD.).

The urea dynamic model was used to evaluate the overall urea clearance judgment of a single dialysis effect, and Kt / V was calculated according to the Daugirdas formula. Kt / V= -ln (BUN before dialysis / BUN after dialysis-0.008 t) + (4-3.5 BUN before dialysis /BUN after dialysis) ultrafiltration volume / dialysis body weight. Long-term dialysis components are protein catabolism rate (calculated by Gotch formula) and time-average urea concentration (calculated by Lowrie formula). Protein catabolism rate = 9.35G×0.29Vt.

The efficacy of the two groups was compared with the TCM syndrome points and the biochemical examination indexes.
