Sepsis is a systemic inflammatory response to infection and includes severe sepsis, septic shock and death. Platelet endothelial cell adhesion molecule-1 (PECAM-1) is one cell adhesion molecule expressed on platelets and leukocytes. It regulates platelet activation and mediates transendothelial migration of leukocytes, thus maintaining the integrity of the vasculature. ⋯ Among sepsis patients, the serum levels of sPECAM-1 were significantly higher in CG and GG genotype than in CC genotype. In septic shock patients, nonsurvivors (83.7 ± 12.6 ng/ml, n = 69) had a significantly higher serum sPECAM-1 level than the survivors (76.9 ± 12.7 ng/ml, n = 53) (P<0.01). In conclusion, PECAM-1 Leu125Val polymorphism and its sPECAM-1 levels are associated with sepsis severity and susceptibility to septic shock.

To compare the effects of general anesthesia combined with epidural preemptive analgesia with general anesthesia on stress reaction in the retroperitoneal laparoscopic surgery. ⋯ Compared with general anesthesia, general anesthesia combined with epidural preemptive analgesia can effectively alleviate patients' stress reaction under retroperitoneal laparoscopic surgery.

To observe the potency ratio of hyperbaric to isobaric solutions of ropivacaine in subarachnoid block for knee arthroscopy. ⋯ The ED50 of hyperbaric ropivacaine is less than that of isobaric ropivacaine in subarachnoid block anesthesia for knee arthroscopy.

Lipopolysaccharide (LPS) is known to induce acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Accumulating data suggest the crucial role of RAGE in the pathogenesis of ALI/ARDS. However, the mechanism by which RAGE mediates inflammatory lung injury in the neonates remains elusive. ⋯ Furthermore, RAGE antibody or bortezomib significantly reduced LPS-induced upregulation of RAGE and NF-κB expression in the lung. In conclusion, we established ALI model in neonate rats to demonstrate that LPS induced inflammatory lung injury via RAGE/NF-κB signaling. Interference with RAGE/NF-κB signaling is a potential approach to prevent and treat sepsis-related ALI/ARDS.

The purpose of the study was to evaluate the neuroprotective effect of dexmedetomidine on anesthesia recovery period and postoperative cognitive function of patients after robot-assisted laparoscopic radical cystectomy and ileal conduit diversion. ⋯ Dexmedetomidine had a neuroprotective effect on anesthesia recovery and postoperative period of the elderly patients undergone robot-assisted laparoscopic radical cystectomy, which might be related to the reduction of inflammatory reaction induced by dexmedetomidine.
