High mobility group box 1 (HMGB-1) has recently received attention as a late mediator of lipopolysaccharide-induced shock, and is thought to function as a mediator in such a disorder as multi-organ failure (MOF). In Japan, we have access to an immobilized polymyxin B fiber column using a direct hemoperfusion (PMX-DHP) for patients with septic shock to improve hemodynamics and organ dysfunction. In this study, we looked at HMGB-1 levels in each category based on the sequential organ failure assessment (SOFA) scores to further dissect its importance in specific aspects of organ failure in patients undergoing PMX-DHP. ⋯ Our results indicate that HMGB-1 is a useful prognostic biomarker in sepsis-induced organ failure in patients undergoing PMX-DHP.

In this study, we investigated the efficacy of a fibrinogen/thrombin-coated collagen patch (TachoSil) to terminate severe bleeding in a coagulopathic pig model with blunt liver injury. ⋯ TachoSil under severe coagulopathy effectively controlled bleeding and successfully prevented hemorrhagic death.

Near-infrared spectroscopy (NIRS) has been shown to provide reliable noninvasive monitoring of regional oxygenation in a variety of clinical settings. We set out to test its feasibility as a monitor of fetal and placental oxygenation during fetal cardiac surgery. ⋯ This is the first report of application of NIRS in the setting of fetal surgery. NIRS permits noninvasive assessment of placental oxygen saturation and pO(2). This technology is a simple and useful tool for real-time monitoring of oxygen delivery to the fetus during maternal-fetal cardiac interventions and of overall well-being of the fetal-placental unit.

Systemic inflammatory response syndromes involving sepsis continue to have extremely high mortality rates. Inflammation is difficult to control when it spreads throughout the body and often progresses into multiple organ dysfunction, eventually leading to death. Cepharanthine (CE) is a plant alkaloid that possesses bioactive properties, with various known actions. In the present study, we investigated protective effects of CE in a lipopolysaccharide (LPS)-induced systemic inflammatory response model and examined underlying mechanisms. ⋯ These results suggest that CE exerts protective effects, at least in part, via NF-κB inhibition. CE may thus be a potential agent for treating systemic inflammatory response syndromes such as sepsis.

Randomized Controlled Trial
The effect of intraperitoneal ropivacaine on pain after laparoscopic colectomy: a prospective randomized controlled trial.
Although laparoscopic procedures are becoming more common, postoperative pain remains a major factor causing delayed patient recovery. There have been several trials to reduce pain by instilling local anesthetics into the peritoneal cavity, but there has been no study on prolonged (∼300 min) or intensive surgery. We investigated the analgesic effect of intraperitoneal ropivacaine instillation after laparoscopic colectomy. ⋯ The intraperitoneal instillation of ropivacaine was effective in reducing postoperative pain and in shortening the recovery course after laparoscopic colectomy. The additional instillation of ropivacaine at the end of the surgery proved even more effective.
