Objective To explore the effect of alpha lipoic acid and Shuxuetong on oxidative stress and insulin resistance in patient with type 2 diabetes mellitus(T2DM)and to guide the clinical therapy for T2DM.Methods Totally 90 cases of T2DM pa-tients were sellected from Hainan Province Nongken Hospital.The patients were divided into Shuxuetong group(group A,n=30), alpha lipoic acid group(group B,n=30)and alpha lipoic acid and Shuxuetong group(group C,n =30).HOMA-IR,HOMA-β,and HOMA-ISI was calculated.SOD was determined by xanthine oxidase method.MDA was detected by Thiobarbituric acid method. The expression of IL-6 and TNF-αwas determined by ELISA analysis.Results Before treatment,SOD,MDA,IL-6,TNF-α,HO-MA-IR,HOMA-ISI,and HOMA-βwas no significant difference among the three groups(P >0.05).After treatment,all of which was significantly changed(P <0.05 and P <0.01).SOD,HOMA-ISI and HOMA-βin group C was significantly higher than that in group B(P <0.05),and which was significantly higher in group B than that in group A (P <0.05).MDA and HOMA-IR in group C was significantly lower than that in group B(P <0.05),and which was significantly lower in group B than that in group A (P <0.05).IL-6 and TNF-αin group C was lower than that in group A and group B(P <0.01),and which was no significant difference between group A and group B(P >0.05).Conclusion Alpha lipoic acid combined with Shuxuetong injection can significantly im-prove the oxidative stress state of T2DM patients,inhibit the inflammatory reaction,improve insulin resistance and patient′s sensi-tivity to insulin.Which was contribute to clinical treatment for T2DM.
