In recent years, many researches have indicated that metabolic syndrome was closely related to the occurrence and development of colorectal adenomatous polyps, and was related to the recurrence of colorectal adenomatous polyps after resection. The possible mechanisms of metabolic syndrome affecting colorectal adenoma include chronic inflammation, insulin resistance and oxidative stress, and intestinal flora changes. Therefore, identifying metabolic syndrome and associated diseases are of great significance in the prevention, treatment and monitoring recurrence of colorectal adenomatous polyps in clinical practice. This article reviewed the correlation between metabolic syndrome and colorectal adenomatous polyps.

With the rapid change in lifestyle in recent years, the prevalence rate of nonalcoholic fatty liver disease (NAFLD) is increasing year by year and it has gradually become one of the major causes of chronic liver diseases. With the development of the bio-psycho-social medical model, the influence of psychological diseases on physical diseases has attracted the attention of scholars. At present, evidence has shown that anxiety, as one of the most common type of mental disorders, may be associated with the development of NAFLD. This article introduces the current status of research on anxiety and NAFLD and their common influencing factors and predicts the possible pathophysiological mechanism of NAFLD caused by anxiety, so as to lay a foundation for further research on the association between anxiety and NAFLD and provide new directions for the treatment of NAFLD.
