骨骼肌作为调节机体糖代谢的重要外周组织,在基础状态和胰岛素刺激情况下,对糖的摄取利用量分别约占全身组织的2 0 %和75 %～95 % [1] 。在生理状态下,葡萄糖由骨骼肌细胞外向细胞内的转运过程是糖利用的主要限速步骤[2 ] 。胰岛素和肌肉收缩是生理状态下调节骨骼肌细胞糖转运 Skeletal muscle plays an important role in the regulation of glucose metabolism in peripheral tissues. Under the condition of basal state and insulin stimulation, the uptake of sugar accounts for about 20% and 75% -95% of the total body tissue, respectively [1]. Under physiological conditions, glucose is transported from skeletal muscle cells to the outside of the cells as the main rate-limiting step in sugar utilization [2]. Insulin and muscle contraction are physiologically regulated sugar transport in skeletal muscle cells
