Development and validation of a model to predict the need for artificial airways for acute trauma patients in the emergency department: a retrospective case-control study.

Objective: To develop scores for predicting the need for artificial airway procedures for acute trauma patients in the emergency department (ED).

Design: Retrospective case-control.

Setting: A tertiary comprehensive hospital in China.

Early extracorporeal membrane oxygenation as bridge for central airway obstruction patients caused by neck and chest tumors to emergency surgery.

Central airway obstruction caused by neck and chest tumors is a very dangerous oncological emergency with high mortality. Unfortunately, there is few literature to discuss an effective way for this life-threating condition. Providing effective airway managements, adequate ventilation and emergency surgical interventions are very important.

Efficiency of free thyroxine in predicting severity and mortality of patients with acute pancreatitis: A protocol for systematic review and meta-analysis.

Background: Previous studies suggest that free thyroxine may be used as a severity indicator of patients with acute pancreatitis (AP) in emergency department, helping determine the differential care of AP. However, there are no systematic reviews and the association between free thyroxine and AP is still not completely understood. Therefore, we will undertake a systematic review of the literature to summarize previous evidence regarding this topic, in order to clarify whether free thyroxine can help us pick out the mild AP cases.

[Effects of Scalp Acupuncture on Serum NSE and S-100β Concentrations and Postoperative Cogni- tive Function of Elderly Patients Undergoing Hip Replacement].

Objective: To explore the effect of Scalp acupuncture on serum neuron specific enolase (NSE) and S-100β concentrations, and incidence rates of postoperative delirium (POD) and postoperative cognitive function (POCD) of elderly patients undergoing hip replacement.

Methods: Eighty-four patients undergoing scheduled hip replacement under combined spinal-epidural anesthesia (CSEA) were assigned to the control group (group C) and the scalp acupuncture group (group S) according to random digit table, 42 cases in each group. In group S, scalp acupuncture was additionally performed according to International Standardized Scheme for Scalp Acupuncture.

Chief complaints associated with mortality involving civilian transport after Wen-chuan earthquake.

Objectives: Previous studies have reported that civilian transport is a mortality risk factor in low-resource communities. Few studies have analyzed the chief complaints associated with mortality involving civilian transport after an earthquake.Therefore, the present study was conducted to determine whether mortality resulting from medical professional transport differs from that involving civilian transport, and if so, the chief complaints associated with mortality involving civilian transport after the Wen-chuan earthquake.

[Effects of parecoxib sodium analgesia on serum concentrations of neuron-specific enolase and S-100β and postoperative cognitive function of elderly patients undergoing acute replacement of femoral head].

Objective: To explore the effects of parecoxib sodium analgesia on serum concentrations of neuron-specific enolase (NSE) and S-100β and postoperative cognitive function of elderly patients undergoing acute replacement of femoral head.

Methods: After the approval of institutional review board and the provision of informed consent, 80 patients over 70 years old, undergoing acute replacement of femoral head under combined spinal and epidural anesthesia and midazolam sedation at Qingdao Municipal Hospital and Qingdao Hiser Medical Center from January 2011 to May 2012, were randomly assigned into control group (group C, n = 40) and parecoxib group (group P, n = 40). In group P, parecoxib sodium 20/40 mg (based on weight 50 kg) was administered via an intravenous injection after admission with 12 hours intervals for six times.

[Expression of NF-kappaB and its downstream products in human umbilical vascular endothelial cells treated with paraquat].

Objective: To investigate the expression of NF-kappaB and its downstream products in the human umbilical vascular endothelial cells (HUVEC) treated with paraquat.

Methods: The HUVEC were cultured in vitro. The activation and location of NF-kappaB P65 protein were detected by immunocytochemical method at 8 h, 24 h and 48 h after treatment with paraquat.
