ABSTRACT
The defense and repair function of the gastrointestinal mucosa is of great significance for protecting the integrity of mucosa. A large number of studies have shown that the defense and repair system of gastrointestinal mucosa is a three-dimensional network system, and gut hormones participate in the whole process, thereby playing an important role for diseases related to mucosal injury. This article reviewed the roles of gut hormones in mucosal defense and repair.
ABSTRACT
Glutamine is not only a special nutritional substance but a conditional essential amino acid,which is the most abundant amino acids in plasma,representing about 60％ of free amino acids in the body,and it's normal plasma concentration is from 0.6 to 0.9 mmol/L.In recent years,with the increasing deepening study of the field of clinical nutrition,the concept of glutamine study has been gradually changed gradually changed it's concept from a simple nutritional support to immune nutrition therapy.Glutamine can not only improve the body's protein levels of nutrition,protect the gastrointestinal mucosa,but also reduce the incidence of infection and the inflammation in the body,improve immune function,reduce side effects of chemotherapy,and at the same time enhance tumor sensitivity to chemotherapy and promote gastrointestinal cancer patients' postoperative recovery,reduce surgical complications.This paper aims to review the application and research of glutamine in the gastrointestinal cancer patients after the operation.
