【摘要】：目的:研究運動與羅格列酮聯(lián)合對T2DM大鼠ADMA水平的影響,觀察其是否存在協(xié)同效應(yīng)。方法:采用高質(zhì)飲食結(jié)合腹腔注射低劑量STZ的方法建立T2DM大鼠模型,將實驗動物分為正常對照組、T2DM組、T2DM+運動組、T2DM+羅格列酮組和T2DM+運動+羅格列酮組,每組給予相應(yīng)的干預(yù)10周。結(jié)果:羅格列酮可以降低T2DM大鼠CML(P0.01)和ADMA(P0.01),同時上調(diào)肝臟PPAR-γ(P0.01)和DDAH-1(P0.01)mRNA表達,而運動可以降低T2DM大鼠CML(P0.01)和ADMA(P0.05),同時上調(diào)肝臟PPAR-γ(P0.05)和DDAH-1(P0.01)mRNA表達;運動和羅格列酮聯(lián)合干預(yù)組CML明顯低于羅格列酮單獨干預(yù)(P0.01),ADMA明顯低于單獨運動干預(yù)(P0.05),肝臟PPAR-γ和DDAH-1mRNA表達分別顯著高于單獨運動((P0.01)和單獨羅格列酮(P0.01)干預(yù)。結(jié)論:運動和羅格列酮在降低ADMA保護血管內(nèi)皮方面可能存在協(xié)同效應(yīng),其機制可能是基于AGEs/PPAR-γ/DDAH/ADMA途徑。
[Abstract]:Objective: to study the effect of exercise combined with rosiglitazone on ADMA level in T2DM rats. Methods: T2DM rat model was established by high quality diet and intraperitoneal injection of low dose STZ, and the experimental animals were divided into normal control group and T2DM group. Rosiglitazone group in T2DM exercise group and rosiglitazone group in T2DM exercise group. Results: rosiglitazone could reduce CML P0.01 and ADMAP 0.01) in T2DM rats. At the same time, the expression of PPAR- 緯 P0.01) and DDAH-1(P0.01)mRNA were upregulated. However, exercise could decrease the levels of CML P0.01 and ADMA-P0.05 in T2DM rats. At the same time, the expression of PPAR- 緯 P0.05) and DDAH-1(P0.01)mRNA were upregulated. CML in combined exercise and rosiglitazone intervention group was significantly lower than that in rosiglitazone alone intervention group (P0.05). The expression of PPAR- 緯 and DDAH-1mRNA in liver was significantly higher than that of P0.01) and rosiglitazone alone (P0.01). Conclusion: exercise and rosiglitazone may have synergistic effects on the protection of vascular endothelium from ADMA. The mechanism may be based on the ages / PPAR- 緯 -DDAH / ADMA pathway.
