目的:探讨运动训练、EGCG单独干预及联合应用对2型糖尿病大鼠主动脉AGEs含量和Col Ⅰ、Col Ⅳ、FN表达的影响。方法:通过高脂喂养加腹腔注射小剂量链脲佐菌素(STZ)构建2型糖尿病SD大鼠模型。将造模成功的68只大鼠随机分为糖尿病对照组(D)、糖尿病给药组(DY)、糖尿病运动组(DE)、糖尿病运动给药组(DEY),每组17只,另设正常对照组(C)10只。运动组大鼠进行12周不负重游泳训练,每周训练5 d。EGCG给药组大鼠每周灌胃7 d。实验结束后检测大鼠血液GLU、GHb、GSP和主动脉AGEs、Hyp、SOD、MDA、Col Ⅰ、Col ⅠV、FN水平的变化,并对实验结果进行统计分析。结果:与正常对照组(C)相比,糖尿病对照组(D)的血液GLU、GHb、GSP和主动脉AGEs、Hyp、Col Ⅰ、Col ⅠV、FN、氧化应激水平均显著升高(P〈0.01);糖尿病给药组(DY)、糖尿病运动组(DE)、糖尿病运动给药组(DEY)的血液GLU、GHb、GSP和主动脉AGEs、Hyp、Col Ⅰ、Col ⅠV、FN、氧化应激水平均显著降低(P〈0.05或P〈0.01);糖尿病运动给药组(DEY)血液GLU、GHb和主动脉AGEs、Hyp显著低于糖尿病给药组(DY)和糖尿病运动组(DE)(P〈0.05或P〈0.01),血液GSP和主动脉氧化应激水平、Col Ⅰ表达显著低于糖尿病运动组(DE)(P〈0.05)。结论:2型糖尿病大鼠存在主动脉间质胶原沉积的现象。运动训练和EGCG可改善2型糖尿病大鼠主动脉间质胶原沉积,且二者共同干预效果好于单一因素干预。这可能与运动和EGCG降低血糖、动脉AGEs含量及AGEs-RAGE下游与胶原代谢相关的信号通路效应有关。
目的:探討運動訓練、EGCG單獨榦預及聯閤應用對2型糖尿病大鼠主動脈AGEs含量和Col Ⅰ、Col Ⅳ、FN錶達的影響。方法:通過高脂餵養加腹腔註射小劑量鏈脲佐菌素(STZ)構建2型糖尿病SD大鼠模型。將造模成功的68隻大鼠隨機分為糖尿病對照組(D)、糖尿病給藥組(DY)、糖尿病運動組(DE)、糖尿病運動給藥組(DEY),每組17隻,另設正常對照組(C)10隻。運動組大鼠進行12週不負重遊泳訓練,每週訓練5 d。EGCG給藥組大鼠每週灌胃7 d。實驗結束後檢測大鼠血液GLU、GHb、GSP和主動脈AGEs、Hyp、SOD、MDA、Col Ⅰ、Col ⅠV、FN水平的變化,併對實驗結果進行統計分析。結果:與正常對照組(C)相比,糖尿病對照組(D)的血液GLU、GHb、GSP和主動脈AGEs、Hyp、Col Ⅰ、Col ⅠV、FN、氧化應激水平均顯著升高(P〈0.01);糖尿病給藥組(DY)、糖尿病運動組(DE)、糖尿病運動給藥組(DEY)的血液GLU、GHb、GSP和主動脈AGEs、Hyp、Col Ⅰ、Col ⅠV、FN、氧化應激水平均顯著降低(P〈0.05或P〈0.01);糖尿病運動給藥組(DEY)血液GLU、GHb和主動脈AGEs、Hyp顯著低于糖尿病給藥組(DY)和糖尿病運動組(DE)(P〈0.05或P〈0.01),血液GSP和主動脈氧化應激水平、Col Ⅰ錶達顯著低于糖尿病運動組(DE)(P〈0.05)。結論:2型糖尿病大鼠存在主動脈間質膠原沉積的現象。運動訓練和EGCG可改善2型糖尿病大鼠主動脈間質膠原沉積,且二者共同榦預效果好于單一因素榦預。這可能與運動和EGCG降低血糖、動脈AGEs含量及AGEs-RAGE下遊與膠原代謝相關的信號通路效應有關。

In order to investigate the impact of exercise and EGCG on arterial non-enzymatic glycosylation,Col Ⅰ,Col Ⅳ and FN expression of type 2 diabetes,the authors established a model for type 2 diabetes.Methods: They were randomly divided into group D,DY,DE,DEY,and additionally provided a comparison group C.The rats of group DE were arranged to do non-intensive swimming exercise 5 days for 12 weeks while and the rats of group were given gastry lavage for 7 days per week.After the experiment,rats’GLU,GHb,GSP of blood and AGEs,Hyp,SOD,MDA,Col Ⅰ,Col Ⅳ,FN changes of artery were tested.Result: The level of blood GLU,GHb,GSP and the level of artery AGEs,Hyp,Col Ⅰ,Col Ⅳ,FN,oxidative stress in group D were significantly higher than those in group C(P〈0.01);The level of blood GLU,GHb,GSP and the level of artery AGEs,Hyp,Col Ⅰ,Col Ⅳ,FN,in group DY,DE,DEY were significantly lower than those in group D(P〈0.05 or P〈0.01);The levels of blood GLU,GHb and the level of artery AGEs,Hyp in group DEY were significantly lower than those in group DY,DE(P〈0.05 or P〈0.01),and the level of blood GSP,artery oxidative stress,Col Ⅰ were significantly lower than those in group DE(P〈0.05).Conclusion: The rats of type 2 diabetes had the phenomenon of arterial collagen deposition.Exercise and EGCG could improve arterial collagen deposition in type 2 diabetic rats,which may be related to lower blood GLU and arterial AGEs content,the downstream signaling pathway effect of AGEs-RAGE regulating collagen metabolism.
