INS and type 2 diabetes mellitus: As can be seen from Figure 2, the secretion of insulin was significantly increased in the DM group (34.83 ± 2.73 mmol/L) compared with that in the NC group (16.93 ± 2.62 mmol/L) (p < 0.05), but it was the opposite case for the FBG level (Figure 1), indicating that the experimental mice suffered from T2DM.
