有氧运动联合黄精多糖对非酒精性脂肪肝大鼠TNF-α、NF-κB蛋白表达的影响

有氧运动联合黄精多糖对非酒精性脂肪肝大鼠TNF-α、NF-κB蛋白表达的影响摘要：本文旨在探究有氧运动联合黄精多糖对非酒精性脂肪肝大鼠TNF-α、NF-κB蛋白表达的影响。采用60只雄性SD大鼠，随机分为正常组、模型组、有氧运动组、黄精多糖组和有氧运动联合黄精多糖组。除正常组外，其余组采用高脂饮食及生活环境改变建立非酒精性脂肪肝大鼠模型。有氧运动组和有氧运动联合黄精多糖组在有氧运动训练的基础上分别口服黄精多糖。实验进行8周后，检测大鼠肝脏组织中TNF-α、NF-κBmRNA及蛋白表达情况。结果表明，有氧运动联合黄精多糖对非酒精性脂肪肝大鼠TNF-α、NF-κB蛋白表达水平的调节作用更显著，能有效缓解脂肪肝病变程度，提高大鼠肝脏的抗氧化能力。本研究揭示了有氧运动与黄精多糖联合应用对非酒精性脂肪肝的预防和治疗具有重要意义。
