RESUMO
Objective :To explore therapeutic effect of insulin pump combined alprostadil on diabetic peripheral neu-ropathy (DPN) in aged patients .Methods : A total of 134 aged DPN patients treated in our hospital were selected and randomly , equally divided into routine treatment group and combined treatment group (received insulin pump combined alprostadil based on routine treatment ) ,both groups were treated for two weeks .Therapeutic effect ,lev-els of blood lipids ,serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) before and after treat-ment were compared between two groups .Results : After treatment , total effective rate of combined treatment group was significantly higher than that of routine treatment group (92-5% 比74-6%, P＝0-005).Compared with routine treatment group after treatment ,there were significant rise in serum levels of SOD [ (78-54 ± 9-48) nU／ml vs.(88-29 ± 9-08) nU／ml] ,GSH-Px [(486-53 ± 32-84) U／L vs.(552-31 ± 89-86) U／L] and high density lipopro-tein cholesterol [HDL-C ,(5-88 ± 1-48) mmol／L vs.(6-59 ± 1-63) mmol／L] ,and significant reductions in serum levels of triglyceride [TG ,(2-05 ± 0-34) mmol／L vs.(1-35 ± 0-26) mmol／L] and low density lipoprotein choles-terol [LDL-C ,(3-48 ± 0-48 ) mmol／L vs.(2-48 ± 0-88 ) mmol／L ] in combined treatment group , P＝ 0-001 all. Conclusion : Insulin pump combined alprostadil possess significant therapeutic effect on aged DPN patients .It can significantly improve blood lipid levels ,and relieve oxidative stress state ,which is worth extending .
