The invention discloses a construction method of a type 2
diabetes mellitus primate model, the method comprises the following steps that a middle-year experimental monkey is taken, high-glucose and high-fat feed is fed, the
flameout time of a cage is 2: 00 to 12: 00, the normal
flameout time is adjusted to be 20: 00 to 6: 00 of the next day after two weeks, the normal
flameout time is adjusted to be 2: 00 to 12: 00 after two weeks, in this way, the flameout time is changed alternately, and after at least 6 months, molding is completed. According to the method, the method of disturbing animal
circadian rhythm and
eating time is used for the first time to force non-human
primate experimental animals to change work and
rest time, meanwhile, high-glucose and high-
fat diet modeling is combined, the modeling efficiency is remarkably improved, and the modeling period is shortened by more than 50%; and the method is similar to natural
pathogenesis, and the diabetes symptom is still maintained after induction is stopped half a year, which indicates that the model can be used as a stable T2DM model.
