They were randomly divided into the observation group and the control group, then they were treated with metformin or placebo for 52 months. We compared the level of FPG、PPPG、HbA1c、Vit B12、MMA and Neuropathy Scores before and after treatment between the two groups.Results After treatment with metformin for 3 years, FPG, PPPG and HbA1c in the observation group were decreasing significantly(P<0.05), and those in the observation group were significantly lower in the control group. The scores ofneuropathy and MMA in the two groups were increasing significantly, the observation group was significantly higher than the control group (P<0.05). Meanwhile, Vit B12 were decreasing significantly, the observation group was significantly lower than the control group (P<0.05).Conclusions Metformin not only reduces serum levels of B12, but also increases serum MMA progressively. The increase of MMA was associated with the NPS significantly. These results suggested that monitoring of B12 in users of metformin should be considered"/> 12;MMA;神經(jīng)系統(tǒng)病變;Metformin;type 2 diabetes mellitus;Vit B12;Methylmalonic acid;neuropathy"/>
