[Studies on the cell markers of endothelial function in sepsis].

Objective: To study the phasic changes of the number of circulating endothelial cells (CEC) and endothelial microparticles (EMP) during the process of sepsis.

Methods: Thirty-one patients with sepsis were divided into mild group (<9), moderate group (9-15) and severe group (>15) according to the acute physiology and chronic health evaluation II (APACHE II) scores after onset, and each group was further divided into survivors and non-survivors.The level of CEC, EMP and pro-inflammatory cytokines were determined on 1, 2, 3, 7, 14 days after onset.
