ABSTRACT
Objective To study the influence of probucol on the diabetic mellitus patients with non-proliferative diabetic retinopathy (NPDR) about blood lipids,serum level of the total antioxidant capacity (TAOC),malondialdehyde (MDA),superoxide dismutase (SOD) and macular edema,so as to provide clinical basis for the prevention and treatment of early DR by probucol.Methods 66 type 2 diabetes patients with 127 NPDR eyes were included.Patients were random divided into control and treatment groups,the control group was treated by intensive therapy of blood glucose and blood pressure control,and the treatment group was treated with the intensive therapy and probucol 0.375g,2 times a day for 12 months.Before and after treatment,the blood lipids,oxidative stress indicators and fundus fluorescein angiography in both groups had been determined.Results 62 cases with 120 eyes were enrolled in this study.Probucol obviously decreased levels of total cholesterol (TC) [ (3.6 ± 0.58) mmol/L VS (4.71 ± 0.61)mmol/L,t = 7.65,P < 0.01 ],triglyceride (TG) [ (1.07 ± 0.35) mmol/L VS (1.23 ± 0.43) mmol/L,t = 2.02,P < 0.05 ],low density lipoprotein cholesterol (LDLC) [ (2.0 ± 0.47) mmol/L VS (2.55 ±0.56)mmol/L,t =4.18,P <0.01] and MDA[ (10.35 ±2.97)nmol/L VS (14.83 ±2.75)nmol/L,t =6.18,P <0.01] in plasma of the patients.Levels of TAOC [(19.25±4.11)u/ml VS (16.63 ±3.27)u/ml,t =3.57,P <0.01 ]and SOD[ (94.52 ± 10.28)u/ml VS (75.37 ± 9.87) u/ml,t =8.62,P <0.01]were significantly improved in the probucol group,and the macular edema was significantly reduced in patients of the probucol group(x2 =4.219,P <0.05).Conclusion Probucol regulated serum lipids,and it had the apparent action of antioxidant,and it decreased the incidence of macular edema.Probucol had a therapeutic effect in patients with NDPR.
