Objective To discuss the clinical preventation and treatment of the complications induced by endotracheal intubation in SICU.Methods Retrospective analysis was used on 55 cases of intubated patients in our hospital nearly 2 years.Results The incidence of endotracheal intubation was 36.4％,pneumonia 23.6％,accidental extubation 5.5％,endotracheal ulcer 1.8％,tracheoesophageal fistula 1.8％,obstruction of tracheal catheter 1.8％,arytenoid dislocation 1.8％.Conclusion The causeof complications of endotracheal intubation in SICU were overtime intubation,tranma,excessive-pressure of the air cuff and local inflammation.Airway humidification,suitable sedation,accurate and moderate operation,extubation or tracheotomy,suitable cuff pressure and fiberoptic bronchoscopy examination could avoid such complications.

Silent information regulator 1 (SIRT1) is a NAD+-dependent histone deacetylase,which plays an important role in cerebral ischemia.It mainly stabilizes cerebral vascular endothelium,prevents vascular stenosis and the anti-inflammatory and anti-oxidative stress effects after cerebral ischemia.This article reviews the protective effects of STRT1 and its related mechanisms in cerebral ischemia.

Objective To study the genetic toxicity of carbon tetrachloride for male mice and assess the potential genetic toxic effect on mankind. Methods Micronucleus test and sperm malformation test were used respectively to determine the change of micronucleus cell frequencies (MNCF) and the rate of sperm deformity of germ cell induced by carbon tetrachloride in male mice. Carbon tetrachloride was given through intraperitoneal injection at does of 5,15,25 mg/kg respectively for 24 h and 48 h, the rates of micronucleus in the bone marrow cell and sperm deformity of germ cell of male mice were investigated by counting the number of micronucleus cells per 5 000 polychromatic erythrocyte (PCE) in bone marrow and sperm deformity cells per 5 000 germ cells from male mice. Results The micronucleus rates of PCE in bone marrow and sperms deformity frequencies in carbon tetrachloride treated groups were much higher than the control group (P

The general theories of gray correction methods for the medical ultrasonic image are introduced in this paper, including gray level correction, gray level transformation and histogram correction. The dominant histogram equalization method is expatiated and modified against its disadvantages including inapparent enhancement of partial detail and non-interactivity. Series connections of several gray correction methods are used to treat with the ultrasonic image, and thus its utility is improved through the selective enhancement of the contrast of certain gray scope.
