α-硫辛酸联合疏血通对2型糖尿病患者胰岛功能的影响

目的：观察α-硫辛酸联合疏血通对2型糖尿病(T2DM)患者氧化应激水平及胰岛素抵抗的影响。方法收集该院内分泌科2012年2月至2014年2月治疗的 T2DM 患者90例,分为疏血通治疗组(A 组)、α-硫辛酸治疗组(B 组)和α-硫辛酸联合疏血通治疗组(C 组),每组30例。计算胰岛素抵抗指数(HOMA-IR)、胰岛素分泌指数(HOMA-β)、胰岛素敏感指数(HOMA-ISI)。黄嘌呤氧化酶法测定超氧化物歧化酶(SOD),硫代巴比妥酸法测定丙二醛(MDA),IL-6和 TNF-α表达使用 ELISA 法检测。结果治疗前 A、B、C 3组 SOD、MDA、IL-6、TNF-α、HOMA-IR、HOMA-ISI 和 HOMA-β差异无统计学意义(P >0.05)。治疗后各组上述指标与治疗前比较差异均有统计学意义(P <0.05或 P <0.01)。其中 SOD、HOMA-ISI 和 HOMA-β在 C 组显著高于 B 组(P <0.05),B 组又显著高于 A 组(P <0.05)；MDA 和 HOMA-IR 在 C 组显著低于 B 组(P <0.05)；B 组又显著低于 A 组(P <0.05)。IL-6和 TNF-α在 C 组显著低于 A 组和 B 组(P <0.01),A 组与 B 组间差异无统计学意义(P >0.05)。结论α-硫辛酸联合疏血通可以显著改善 T2DM 患者氧化应激状态,抑制炎性反应,改善胰岛素抵抗,提高患者对胰岛素的敏感性,有利于T2DM 的临床治疗。

The effect of alpha lipoic acid and Shuxuetong on islet function in patient with type 2 diabetes mellitus

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.
