Sepsis is a life-threatening acute inflammatory condition associated with metabolic complications. Accumulation of free fatty acids (FFAs) induces inflammation and causes lipotoxic effects in the liver. Because fatty acid metabolism plays a role in the inflammatory response, we hypothesized that the administration of C75, a fatty acid synthase inhibitor, could alleviate the injury caused by sepsis. ⋯ C75 effectively lowered FFA accumulation in the liver, which was associated with inhibition of inflammation and organ injury as well as improvement in survival rate after CLP. Thus, inhibition of FFA by C75 could ameliorate the hepatic dysfunction seen in sepsis.

Hypothermia can ameliorate ischemia-reperfusion-induced intestinal injury; however, whether the therapeutic mechanism of hypothermia on hemorrhagic shock, a severe condition of ischemia-reperfusion, is associated with mitochondrial protection in enterocytes is rarely reported. We aimed to evaluate the effects of hypothermia on mitochondria after shock-induced intestinal injury. ⋯ The results suggest that moderate hypothermia resuscitation is an effective treatment for shock-induced intestinal injury, and its therapeutic mechanism may be related to mitochondrial protection.

Comparative Study
Fresh frozen plasma: red blood cells (1:2) coagulation effect is equivalent to 1:1 and whole blood.
Preemptive treatment of trauma-associated coagulopathy involves transfusion of fresh frozen plasma (FFP) at 1:1 ratio with red blood cells (RBCs), but the optimal ratio remains controversial. In combat theaters, fresh whole blood (FWB) is also an option. The objective of this study was to determine the effect of FFP:RBC ratios 1:1, 1:2, 1:3 and FWB on coagulation during resuscitation. ⋯ FFP:RBC in a 1:2 ratio optimally harnessed hemostatic resuscitation and prudent use of blood products compared with 1:1 and 1:3 ratios and to FWB transfusion.

Three-dimensional printing (3DP) is gaining increasing recognition as a technique that will transform the landscape of surgical practice. It allows for the rapid conversion of anatomic images into physical objects, which are being used across a variety of surgical specialties. It has been unclear which groups are leading the way in coming up with novel ways of using the technology and what specifically the technology is being used for. The aim of this article was to review the current applications of 3DP in modern surgical practice. ⋯ Different specialties are at different stages in the use of the technology. The costs involved with implementing the technology and time taken for printing are important factors to consider before widespread use. For the foreseeable future, this is an exciting and interesting technology with the capacity to radically change health care and revolutionize modern surgery.

Sepsis is a complex syndrome with high mortality, which often induces acute lung injury (ALI) and acute respiratory distress syndrome. Cyanidin-3-O-glucoside (C3G), the most active anthocyanin in the blueberry extracts, has been demonstrated to have pulmonary protective effects in some ALI models. This study aims to evaluate the potential protective effect of C3G on sepsis-evoked ALI in rats. ⋯ These findings indicate that C3G exerts pulmonary protective effects on CLP-induced ALI rats. The effect may be associated with NF-κB signaling pathway suppression.
