Abstract: To observe the effect of Shizidaiping formula on insulin resistance skeletal muscle cells and to explore its mechanism in improving insulin resistance.Insulin resistant model was developed with 5×107mol/L insulin intervention for 12 h.High,middle and low concentrations of Shizidaiping formula(400,100,25 μg/mL)(SZDP-H,SZDP-M and SZDP-L)were then applied on skeletal muscle cells.Pioglitazone(40 μmol/L)was used as positive control.The content of glucose in skeletal muscle cell supernatant was determined by glucose oxidase method and the expressions of AKT and GSK-3β was detected with Western-blot method.The results showed that Shizidaiping formula can improve glucose metabolism,increase the content of AKT and AKT phosphorylation level,decrease the content of GSK-3β,and increase GSK-3β phosphorylation level.Shizidaiping formula improve glucose metabolism through increasing phosphorylation levels of AKT and GSK-3β.

Key words: Shizidaiping formula, skeletal muscle cell, insulin resistance, AKT/GSK-3&beta
