In this study, the investigators will collect the peripheral blood of 1,3,7,14 day after diagnose of sepsis. Then, the concentration of branched-chain amino acids(BCAAs) in monocytes and plasma, and the expression of BCAAs metabolic enzymes in monocytes will be determined. Additionally, the inflammatory cytokines, e.g., Interleukin-1β (IL-1β), Tumor necrosis factor-α (TNF-α), Interleukin-10 (IL-10）, the chemokines macrophage inflammatory proteins 1α and 1β (MIP-1α and 1β) in the peripheral blood and the phagocytic function of monocytes will also be detected. The current project was designed to examine the metabolic level of branched-chain amino acids in plasm and monocyte/macrophage, and its role in immune dysfunction during sepsis.
