摘要
Objective To study the effect of metformin on lactate metabolism in hepatocytes in vitro under high glucose stress.In vitro LO2 cells,liver cells were randomly divided into blank control group,25 tendency/L glucose solution,27 tendency/L glucose solution,29 tendency/L glucose solution,31 tendency/L glucose solution,33 tendency/L glucose solution,35 tendency/L glucose solution treatment group,the optimal concentation of 31 tendency after L,use 30 tendency for L metformin solution,and then divided into blank control group,the optimal concentration of glucose solution,normal liver cells+metformin solution normal liver cells.The optimal concentration of glucose solution normal liver cells+metformin solution respectively in the 12h,24 h,48 h on cell count plate to calculate the mumber of liver cells,and using lactic acid determination kit the optimal concentration of glucose solution+normal liver cells and normal liver cells+the optimal concentration of glucose solution+metformin solution respectively in the 12 h,24 h,48 h of cell cultures of lactic acid value.There was no significant change in the lactic acid concentration but significant increase in the number of suviving hepatocytes in the high-glycemic control group compared with that in the high-glycemic control group without metformin.Metformin has no significant effect on lactic acid metabolism of hepatocytes under high glucose stess in vito,and has a protective effect on hepatocytes under high glucose stress.Based on this,it is preliminanily believed that metformin is not the direct factor leading to diabetic lactic acidosis.
