Effect of different degrees of adenoid hypertrophy on pediatric upper airway aerodynamics: a computational fluid dynamics study.

To improve the diagnostic accuracy of adenoid hypertrophy (AH) in children and prevent further complications in time, it is important to study and quantify the effects of different degrees of AH on pediatric upper airway (UA) aerodynamics. In this study, based on computed tomography (CT) scans of a child with AH, UA models with different degrees of obstruction (adenoidal-nasopharyngeal (AN) ratio of 0.9, 0.

Involvement of spinal cannabinoid receptor type 2 in the analgesia effect of hyperbaric oxygen treatment on paclitaxel-induced neuropathic pain.

Background: Chemotherapy-induced neuropathic pain (CINP) is intractable, and spinal cannabinoid receptors (CBRs) are potential therapeutic targets for CINP. Previous studies demonstrated that hyperbaric oxygen (HBO2) may contribute in alleviating specific peripheral neuropathic pain. However, neither CINP nor CBR have been clarified.

[The value of bispectral index in the unconscious patients with acute brain injury due to different pathogenic factors].

Objective: To observe the differences in bispectral index (BIS) in unconscious patients with acute brain injury due to different pathogenic factors, and approach its clinical significance.

Methods: A retrospective study was conducted. One hundred and twenty-two unconscious patients with acute brain injured admitted to the intensive care unit (ICU) from March 2009 to August 2012 were involved.

[Evaluation of continuous monitoring of bispectral index in prognosis in patients with acute brain injury].

Objective: To discuss the effect of continuous monitoring of bispectral index (BIS) on the prognosis of patients with acute brain injury.

Methods: A retrospective study was carried out, 61 patients with acute brain injury admitted to the intensive care unit (ICU) from March 2009 to July 2010 were divided into survival group (n=25) and death group (n=36). The BIS was continuously monitored for 12 hours within the first 3 days or 24 hours after stoppage of sedative after admission to ICU.

[Role of neuron specific enolase and S100 protein in evaluation of brain damage in patients resuscitated from cardiac arrest].

Objective: To investigate the prognostic value of serum neuron specific enolase (NSE) and S100 protein in evaluation of brain damage in patients resuscitated from cardiac arrest (CA).

Methods: According to whether the patients regained consciousness after 6 months or not, 25 patients after cardiopulmonary resuscitation (CPR) were divided into 2 groups, and blood samples were obtained for determination of NSE and S100 protein at 2, 12, 24, 48 and 72 hours after recovery of spontaneous circulation (ROSC), then the values at each time point were compared between 2 groups and also with that of 7 healthy volunteers. Receiver operator characteristic (ROC) curves of serum NSE and S100 protein were depicted and used area under curve (AUS) to scale the ability in evaluating the state of consciousness in patients after CPR.
