摘要: 目的:深入观察耐力训练对载脂蛋白E基因敲除(ApoE-/-)致动脉粥样硬化(AS)小鼠白介素18(IL-18)和白介素10(IL-10)的影响,探讨运动防治AS的可能机制。方法:选取8周龄雄性ApoE-/-小鼠20只:随机分为2组(n=10):AS模型组(AC组)和运动干预组(AE组),AE组进行跑台耐力训练;选取8周龄C57BL/6J雄性小鼠10只作为正常对照组(CC组)。实验持续12周,取主动脉制作冰冻切片,分别用于观察主动脉AS斑块和病理变化以及主动脉IL-18、IL-10蛋白表达;采用ELISA法检测血清IL-18、IL-10水平。结果:①12周高脂膳食致ApoE-/-小鼠发生典型的AS病变,耐力训练使AS斑块面积显著减少(P<0.01),病变程度显著减轻。②与CC组比较,AC组、AE组小鼠血清IL-18和IL-10水平均显著升高(P<0.01),且AC组IL-18/IL-10比值显著升高(P<0.01)。AE组血清IL-18水平及IL-18/IL-10比值均显著低于AC组(P<0.01)。③与CC组比较,AC组、AE组小鼠主动脉IL-10和IL-18蛋白表达均显著升高(P<0.01),AE组IL-10表达显著高于AC组(P<0.05),IL-18表达显著低于AC组(P<0.05)。结论:耐力训练通过降低血液和主动脉IL-18及提高IL-10水平,增强了主动脉血管抗炎能力,从而发挥抗AS的作用。

Abstract: Objective:To investigate the effects of endurance training on interleukin-18(IL-18) and IL-10 in atherogenice apolipoprotein E gene knockout(ApoE-/-)mice and explore its possible mechanism preventing atherosclerosis occurrence. Methods:Twenty male ApoE-/- mice (age:8 weeks) were randomly divided into atherosclerosis(AS)model group(AC) and exercise group(AE) and chose male C57BL/6J mice (age:8 weeks) as control group (CC). After 12 weeks, the aortic trunk closed heart was prepared for frozen section, which were used to observe the changes of plaque area and pathology. The expressions of IL-18 and IL-10 proteins and the levels of blood IL-18 and IL-10 were measured by ELISA. Results:① Twelve weeks high fat diet significantly resulted in typical AS lesion, however, endurance training markedly decreased AS plaque area and pathology in ApoE-/- mice(P<0.01). ②Compared with CC group, serum IL-18 and IL-10 levels were significantly increased in AC group and AE group and IL-18/IL-10 ratio was also increased markedly in AE group(P<0.01). Serum IL-18 level and IL-18/IL-10 ratio in AE group were all significantly lower than those in AC group (P<0.01).③Compared with CC group, the expressions of IL-10 and IL-18 proteins in aorta were significantly increased in AC group and AE group (P<0.01). The expression of IL-10 protein in aorta in AE group was markedly higher than that in AC group but IL-18 protein expression was significantly lower. Conclusion:Endurance training can prevent AS appeared through enhancing aortic anti-inflammatory capability by decreasing serum and aortic IL-18 levels and by increasing serum and aortic IL-10 level.

Key words: endurance training, atherosclerosis, interleukin-18, interleukin-10, apolipoprotein E gene knockout mice
