Objective To observe the clinical efficacy of Shuxuening injection combined with compound coenzyme in the treatment of chronic allograft nephropathy (CAN). Methods A retrospective analysis of 108 patients with chronic allograft nephropathy (CAN) admitted to our hospital from June 2014 to May 2018 were divided into two groups according to different treatments. The 43 cases in the experimental group were given Shuxuening injection combined with compound coenzyme, and the 65 cases in control group were given non-Shu Xuening + compound coenzyme. The original immunization protocol was maintained in both groups. After 4 weeks of treatment, the changes of hemodynamic parameters, clinical efficacy, biochemical parameters, coagulation function and adverse reactions were observed before and after treatment. Results There was no significant difference in baseline data between the two groups before treatment (P> 0.05). After treatment, the peak systolic velocity of the intersegmental artery and cortical arteriole in the experimental group were significantly higher than that the control group (P < 0.05) , and the resistance index was lower than that in the control group (P < 0.05). After treatment, serum creatinine, 24 h urine protein quantitation, urinary microalbumin, total cholesterol and triglycerides were lower than that before treatment (P < 0.05) , and estimated glomerular filtration rate (eGFR) and serum. Albumin increased significantly (P < 0.05) , but the 24 h urine protein quantitation and urinary albumin decreased significantly in the experimental group compared with the control group (P < 0.05). After treatment, the total amount of cholesterol, triglycerides showed no significant difference (P> 0.05). After treatment, the platelet count, fibrinogen and D-dimer of the experimental group were significantly lower than those before treatment (P < 0.05) , and the activated partial thrombin time (APT) was significantly higher than that before treatment (P < 0.05). Significant difference in platelet count, fibrinogen, D-dimer and APTT was found after treatment (P < 0.05). After 4 weeks of treatment, the values of urea nitrogen and serum creatinine were significantly lower than those of the control group (P < 0.05). The recovery of transplanted kidney function in the experimental group was higher than that in the control group (P < 0.05). The experimental group reported 2 cases of fatigue complain and 1 case of dizziness, but no special treatment was given to them and their condition improved after symptomatic treatment; 1 case of mild phlebitis which was cured after given slowed drip rate and local hot compress therapy. The incidence of adverse events was 9.3％ (4/43). The control group reported 2 cases of fatigue complain, 1 case of nausea, 1 case of facial flushing, and all cured with no special treatment was given; 1 case of mild phlebitis, and cured after slowed the i.v. drip rate and ocal hot compress; The adverse events rate was 7.7％ (5/65). No serious adverse reactions occurred during the entire clinical trial. There was no significant difference in the incidence of adverse events between the experimental group and the control group (χ2=0.054, P=0.732). Conclusion Combined with Shuxuening injection and compound coenzyme can improve blood flow of transplanted kidney, reduce proteinuria, reduce blood urea nitrogen and creatinine in patients with CAN after renal transplantation and effectively improve patient's hemodynamic parameters and safety.
