Research progress of glycocalyx on endothelium in sepsis / 中华实用儿科临床杂志

ABSTRACT

The mortality of sepsis remains high,and it is still a major cause of death in critically ill patients.But its pathophysiological mechanism remains a mystery,not yet fully clear.Endothelium play an important role in the development of sepsis.Maintaining the integrity of its surface glycocalyx to a certain extent reduces sepsis damage;and its destruction mediates a series of pathophysiological responses,including increasing vascular permeability by cell pathway or intracellular pathways,increasing the adhesion of white blood cells to endothelial cejls and a variety of cytokines to promote inflammatory response,activating of thrombin to coagulation dysfunction,promoting synthesis of nitric oxide to change vascular tension.The damage of glycocalyx as a first step in endothelial cell injury can be used as early diagnosis and prognosis of sepsis,which provides new ideas for the diagnosis and treatment of sepsis.
