Severe burns initiate an inflammatory response characterized by the upregulation of proinflammatory cytokine, which contributes to multiple organ injury. Na(+)/H(+) exchanger 1 (NHE1) plays a significant role in several inflammatory processes. This study was designed to investigate the role of NHE1 in burn-induced inflammation and multiple organ injury. ⋯ These results indicate that NHE1 inhibition prevents burn-induced multiple organ injury. The salutary effects afforded by NHE1 inhibition, at least in part, are mediated by attenuating systemic inflammatory response.

In the first posttransplant month, the most frequent complications are due to technical problems related to complex vascular and bile duct reconstructions during the operation. Moreover, despite great improvements in suturing technique and materials, severe organ ischemia-reperfusion caused by time-consuming hand suturing is still an important factor in graft survival. During the operation, severe hypotension, hypoxic acidosis, hyperkalemia, and renal dysfunction may occur during the anhepatic phase due to the prolonged venous clamping time required for hand suturing. Therefore, hand suturing is a handicap in the development of further advancements in liver transplantation. In this study, we aimed to test a new "mechanical installation method" for rapid vascular reconstruction. ⋯ The magnetic pinning-ring device offers a simple, fast, reliable, and efficacious technique for nonsuturing vascular and bile duct anastomoses. Use of this device shortens operation time, maintains a high patency rate, and improves the healing of tissue. Application of the magnetic ring anastomosis technique can effectively reduce the complications caused by hand suturing, and can reduce the extent of ischemia-reperfusion injury, leading to smoother operations and improved prognosis.

Review Meta Analysis Comparative Study
Clinical benefits of dexmedetomidine versus propofol in adult intensive care unit patients: a meta-analysis of randomized clinical trials.
This meta-analysis was performed to assess the influence of dexmedetomidine and propofol for adult intensive care unit (ICU) sedation, with respect to patient outcomes and adverse events. ⋯ For ICU patient sedation, dexmedetomidine may offer advantages over propofol in terms of decrease in the length of ICU stay and the risk of delirium. However, transient hypertension may occur when dexmedetomidine is administered with a loading dose or at high infusion rates.

Review Meta Analysis Comparative Study
Self-gripping versus sutured mesh for inguinal hernia repair: a systematic review and meta-analysis of current literature.
Lichtenstein tension-free mesh repair is the most commonly used technique for open inguinal hernia. However, mesh fixation with sutures to avoid dislocation has been considered as a cause of chronic pain and discomfort. A new self-gripping mesh (Parietene Progrip; Coviden) has been developed, which is making the use of sutureless for inguinal hernia repair. The aim of this systematic review was to compare the outcomes of open Lichtenstein inguinal hernia repair using new self-gripping mesh or sutured mesh. ⋯ Based on the results, both meshes appear to result in similar postoperation outcomes. Further long-term analysis may guide surgeon selection of adapted mesh for inguinal hernia repair.

Randomized Controlled Trial
The effects of propofol and dexmedetomidine infusion on fluid responsiveness in critically ill patients.
We studied the effects of propofol or dexmedetomidine on preload dependency and fluid responsiveness in critically ill patients. ⋯ We observed that propofol infusion, but not dexmedetomidine infusion, can increase preload dependency and fluid responsiveness in patients with circulatory failure.
