Abstract Objective To observe the effect of 5-hudroxymethyl-2-furfural (5-HMF) on glycolipid metabolism and hepatic function in mice with type 2 diabetes mellitus (T2DM) and hepatic injury. Methods A low, a medium and a high 5-HMF dose group, a model group, and a control group were designed, with ten female ICR mice in each group. The low, medium and high dose group were given 0.27, 0.80 and 2.67 mg/kgbw 5-HMF, respectively, for 12 weeks; while the model group and the control group were given volume controlled deionized water. The model group and three dose groups were fed with high-fat and high-sugar food (36%), and the intraperitoneal injection of alloxan (60 mg/kgbw) was executed in the 10th and 11th week; the control group were fed with normal food. The body weight, blood glucose, blood lipid, and liver function of mice were determined regularly. The livers were stained by periodic acid Schiff and the changes in pathology were observed. Results Compared with the control group, the serum levels of glucose (GLU), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) were significantly higher in the model group (P<0.05). Compared with the model group, the AST level in the low and high 5-HMF dose group, and the LDH level in the low, medium and high 5-HMF dose group, were significantly lower (P<0.05). There were no significant differences in the levels of GLU, total cholesterol, LDL-C, triacylglycerol, HDL-C and ALT between the model group and the three dose groups (P>0.05). Moderate to severe vacuolar degeneration was observed in the model group, while mild vacuolar degeneration was observed in the high dose group. Medium or large amount of hepatic glycogen granules were observed in the high dose group and the model group. Conclusion Under the conditions of this experiment, 5-HMF does not show any obvious function of reducing blood glucose and lipid in the mice with T2DM and liver injury, but show some protective effects on liver function．
