Objective To explore the influence and curative effect of leflunomide combined with ginkgo leaf extract and dipyridamole on hypercoagulable state in patients with nephrotic syndrome.Methods Ninety-five patients who were the first diagnosed nephrotic syndrome were divided into experiment group (50 cases) and control group (45 cases) by random digits table method.The patients in experiment group were treated with leflunomide combined with ginkgo leaf extract and dipyridamole,while the patients in control group were treated with leflunomide.The coagulation function and renal function indexes were respectively detected before and after treatment.Results After treatment,the expression level of platelet activation complexes (PAC)-1 in experiment group decreased from (7.33 ± 1.69)％ to (2.58 ±0.97)％,and the expression level of CD62p decreased from (6.15 ± 1.59)％ to (3.18 ± 1.03)％,which were significantly lower than those after treatment in control group [(7.23 ± 1.41)％ and (5.99 ± 1.51)％],and there were statistical differences (P ＜ 0.05).The prothrombin time in experiment group extended from (10.62 ±0.45) s to (12.88 ± 0.69) s,and the activated partial thromboplastin time extended from (23.33 ± 2.79) s to (30.57 ±3.88) s,which were significantly longer than those after treatment in control group [(11.21 ±0.48) s and (23.46 ± 2.79) s],and there were statistical differences (P ＜ 0.05).The plasma D-dimer in experiment group decreased from (2.58 ± 1.23) mg/L to (0.89 ± 1.12) mg/L,the plasma fibrinogen decreased from (3.68 ± 1.21) g/L to (1.89 ± 0.74) g/L,which were significantly lower than those after treatment in control group [(2.33 ± 1.22) mg/L and (3.25 ± 1.33) g/L],and there were statistical differences (P＜0.05).The serum creatinine,blood urea nitrogen and 24 h urine protein levels after treatment in the 2 groups were significantly lower than those before treatment,but the serum creatinine and 24 h urine protein levels after treatment in experiment group were significantly lower than those in control group [(85.38 ± 18.56) μ mol/L vs.(115.23 ± 20.88) μ mol/L,(1.07 ± 0.38) g vs.(2.57 ± 0.99) g],and there were statistical differences (P ＜0.05).Conclusions The application of the leflunomide combined with ginkgo leaf extract and dipyridamole has great effects on releasing the hypercoagulable state and improving the renal function of patients with nephrotic syndrome.
