Patients all underwent regularly prescribed dialysis; blood urea nitrogen, creatinine, lipid and albumin were measured to calculate RRF,KT/V,clearance of creatinine (Ccr/w),PV/S and protein catabolic rate (PCR). Daily protein intakes (DPI) was evaluated.

• 患者均采用常规处方透析 ,并抽血检测生化、血脂及蛋白营养指标 ,计算RRF、尿素清除指数 (KT/ V)、周肌酐清除率 (Ccr/ w)、单位透析剂量 (PV/ S)及蛋白质分解率 (PCR) ,评估每日蛋白质摄入量(DPI)。
