Objective:To investigate the efficacy of high-flux hemodialysis combined with hemoperfusion in patients with uremia.Methods:Eighty patients with uremia who received treatment at the Quzhou Hospital Affiliated to Wenzhou Medical University (Quzhou People's Hospital) from January 2020 to December 2022 were selected for this prospective randomized controlled trial. Participants were grouped using a random number table method, with 40 patients in the study group receiving high-flux hemodialysis combined with hemoperfusion, and 40 patients in the control group receiving high-flux hemodialysis alone. Toxicity clearance, calcium-phosphate metabolism, immune function, and vascular endothelial function were assessed using competitive enzyme-linked immunosorbent assay, immunofluorescence assay, fully automated biochemical analyzers, and immunoturbidimetric assay. The differences in toxicity clearance, calcium-phosphate metabolism, immune function, and vascular endothelial function were compared between the two groups.Results:Compared with before treatment, both groups showed a significant decrease in parathyroid hormone (PTH), blood creatinine, β 2-microglobulin, blood urea nitrogen, blood phosphorus, advanced glycation end products (AGEs), intercellular adhesion molecule-1 (ICAM-1), and homocysteine (Hcy) after treatment. Specifically, PTH levels decreased from (353.28 ± 50.26) ng/L to (235.26 ± 31.51) ng/L in the control group and from (357.17 ± 52.18) ng/L to (174.16 ± 26.35) ng/L in the study group; blood creatinine decreased from (969.47 ± 110.44) μmol/L to (511.57 ± 91.96) μmol/L in the control group and from (957.58 ± 121.99) μmol/L to (414.37 ± 87.41) μmol/L in the study group; β 2-microglobulin decreased from (40.27 ± 7.98) mg/L to (22.06 ± 3.26) mg/L in the control group and from (41.65 ± 8.40) mg/L to (17.70 ± 3.43) mg/L in the study group; blood urea nitrogen decreased from (30.64 ± 5.63) mmol/L to (14.02 ± 2.80) mmol/L in the control group and from (30.04 ± 5.90) mmol/L to (10.07 ± 1.94) mmol/L in the study group; blood phosphorus decreased from (2.23 ± 0.49) mmol/L to (1.80 ± 0.36) mmol/L in the control group and from (2.26 ± 0.53) mmol/L to (1.53 ± 0.31) mmol/L in the study group ; Hcy decreased from (35.87 ± 5.34) μmol/L to (30.93 ± 4.65) μmol/L in the control group and from (36.21 ± 5.27) μmol/L to (20.26 ± 4.53) μmol/L in the study group; ICAM-1 decreased from (574.96 ± 56.81) ng/L to (419.87 ± 40.76) ng/L in the control group and from (569.84 ± 52.37) ng/L to (384.51 ± 35.12) ng/L in the study group; AGEs levels decreased from (330.41 ± 43.69) mg/L to (297.64 ± 38.59) mg/L in the control group and from (326.98 ± 41.25) mg/L to (165.42 ± 15.74) mg/L in the study group.
