Abstract 【Objective】To investigate the effects of metformin combined with liraglutide on islet β cell function, liver function and Treg cells in peripheral blood of patients with type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver (NAFLD).【Methods】From January 2015 to December 2016, 93 patients with T2DM complicated with NAFLD were selected and were randomly divided into the observation group (n=47) and the control group (n=46). Two groups of patients were treated with metformin, the observation group received subcutaneous injection of liraglutide, the control group were given subcutaneous injection of insulin glargine. The course of treatment was 3 months. The levels of HbAlcN, FPGN, 2hPGN, FINS, HOMA-IR, HOMA-β, ALT, AST, GGT, TC, TG, HDL-C, LDL-C, and the ratio of Treg cells in peripheral blood to CD4⁺ T cells were compared between the two groups before and after treatment, the decrease in the observation group was more significant than that in the control group (P<0.05). The Treg/CD4⁺ in peripheral blood of the two groups before treatment was 5.62 ±1.80 % and 5.74 ±1.53% respectively, there was no significant difference between the two groups (P>0.05).【Results】Compared with that before treatment, the level of HbAlc, FPG, 2hPG and HOMA-IR decreased after treatment in both groups (P<0.05) and the value of HOMA-βincreased significantly (P<0.05).The level of HbA1c in the observation was lower than that of the control group after treatment, the difference was significant (t=2.230, P=0.028), and the rest indexes has no statistical significance (P>0.05).There was no significant difference in liver function and lipid metabolism between the two groups before treatment (P>0.05). The levels of ALT, AST and GGT in the observation group were lower than those before treatment, and the difference was statistically significant (P<0.05). The levels of ALT, AST and GGT in the control group were not significantly different from those before treatment (P>0.05). The levels of TC, TG, HDL-C and LDL-C in the two groups were lower than those before treatment, the difference was statistically significant (P<0.05), and the Treg/CD4⁺ in the observation group was significantly lower than that in the control group (P<0.05), the difference was statistically significant (P<0.05).【Conclusion】Metformin combined with Lilalutide in the treatment of T2DM patients with NAFLD can effectively restore the function of islet β cells, reduce the degree of insulin resistance, and achieve the purpose of blood glucose control, which is worthy of clinical application.
