Abstract:
Type 2 diabetes (T2D) induced by obesity and high-fat diet is significantly associated with gut microbiota dysbacteriosis. Because the first line clinical medicine of metformin has several intestinal drawbacks, combination usage of metformin with a prebiotic of konjac mannan-oligosaccharides (MOS) was conceived and implemented aiming to investigate whether there were some intestinal synergetic effects and how MOS would function. Composite treatment of metformin and MOS demonstrated synergistic effects on ameliorating insulin resistance and glucose tolerance, also on repairing islet and hepatic histology. In addition, MF+MOS altered the gut community composition and structure by decreasing the relative abundances of family Rikenellaceae and order Clostridiales while increasing an unnamed OTU05945 of family S24-7, Akkermansia muciniphila, and Bifidobacterium pseudolongum. The present study suggested that usage of MOS could augment the hypoglycemic effects of metformin in association with gut microbiota modulation, which could provide references for further medication.

Correlation
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:
