Design: Search the Cochrane Library, ProQuest Academic Journal Library, PubMed, Web of Science, Ovid, Embase, CINAHL complete (EESCO) and other related databases to determine the literature. Screen out articles consistent with this review and summarize them. Results: Since the establishment of the database, a total of 1463 articles have been retrieved. After reading the title, abstract and full text, and excluding non-related and duplicate articles, 22 reports were finally included. Among them, there are 8 articles using different medication methods to compare the effects of establishing a CP model. The included articles explored the effects of different animal models, drug types, and their dose, concentration, speed, and time on the CP model. Conclusion: The factors of dose, concentration and time were positively correlated with the incidence of CP. The effect of speed factors on CP and the results of different animal models are inconsistent. It requires further research in the future.展开更多

Methods: To select T2DM patients who need therapies in hospital from June to September 2017 and divide the patients into study (n?= 41, Dried Noodles) and control (n?= 39, Noodles with Soup) groups. After 3 months, the clinical/biochemical parameters and compliance of two groups were observed. Results: The study group has lower clinical/biochemical parameters and higher compliance than control group for 3 months of intervention. The difference between the two groups is statistically significant (P Conclusion: The improvement of breakfast and health education mode effectively controls T2DM, promotes the development of good living habits of patients, and improves self-management ability and compliance of patients.展开更多
