The anti-oxidative and anti-inflammatory activities of electro-acupuncture (EA), a traditional clinical method, are widely accepted, but its mechanisms are not yet well defined. In this study, we investigated the role of extracellular signal-regulated kinases1/2 (ERK1/2) pathways on electro-acupuncture - mediated up-regulation of heme oxygenase-1 (HO-1) in rabbit lungs injured by LPS-induced endotoxic shock. ⋯ After electro-acupuncture stimulation at ST36 and BL13, severe lung injury during endotoxic shock was attenuated. The mechanism may be through up-regulation of HO-1, mediated by the signal transductions of ERK1/2 pathways. Thus, the regulation of ERK1/2 pathways via electro-acupuncture may be a therapeutic strategy for endotoxic shock.

Autophagy facilitates ventilator-induced lung injury partly through activation of NF-kappaB pathway.
Mechanical ventilation is an important supportive therapy in the intensive care unit (ICU) to assist the critically ill patients with respiratory failure. But longer ventilation time has been proven to contribute to the lung injury which has been recognized as ventilator-induced lung injury (VILI). ⋯ Thus, we propose that autophagy may facilitate ventilator-induced lung injury partly through activation of NF-kappaB pathway, which might be a new potential therapeutic target for ventilator-induced lung injury. Although the exact mechanism of autophagy and its exact role in the VILI need to be further explored, at least it provides us a potential target in the future prevention of VILI.

This study is aimed at evaluating the operation techniques and clinical significance of free flap transplantation combined with skin grafting and vacuum sealing drainage (VSD) in repairing severe traumatic extensive circumferential or semi-circumferential soft-tissue defects of the lower leg. ⋯ Initial debridement and the temporary VSD cover followed after several days by free flap transplantation combined with skin grafting and VSD protection is a reliable treatment regimen for traumatic large circumferential or sub-circumferential soft tissue wounds of the lower leg with deep tissue exposure.

This study was performed to evaluate neck circumference (NC) and metabolic syndrome (MS) parameters in severe and non-severe (mild-moderate) obstructive sleep apnea syndrome (OSAS) patients according to apnea-hypopnea index (AHI). ⋯ In this study. NC in severe OSAS patients was significantly higher than in non-severe OSAS patients. The prevalence of metabolic syndrome was not correlated with OSAS severity. NC is an independent risk factor for severe OSAS.

Comparative Study Clinical Trial
Comparative evaluation of two different volumes of lidocaine in intravenous regional anesthesia.
This study was conducted to compare low concentration-high volume intravenous regional anesthesia (IVRA) method with local anesthetic method in upper extremity surgery in terms of efficiency and adverse effects. ⋯ IVRA technique applied with 2% concentration and volume of 12-15 mL lidocaine may be suggested as a safe option.
