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 investigate whether intraoperative hypotension was associated with postoperative delirium in older patients undergoing laparoscopic surgery with prospective cohort study.Methods Study subjects were patients,＞ 65 years of age,undergoing laparoscopic surgery,who were enrolled in an ongoing prospective observational study of the pathophysiology of postoperative delirium.Intraoperative blood pressure was measured,and predefined criteria were used to define hypotension.Delirium was measured by the Confusion Assessment Method on the first two postoperative days.Data were analyzed with t-test,two-sample proportion test,and ordered logistic regression muhivariable model,including correction for multiple comparison.Results Data from 213 patients with a mean age of 73.6 years (SD 6.1) were studied.Of these 63 (29.6％) developed delirium on day 1 and 61 (28.6％) on day 2.Relative hypotension (decreases by 20％,30％,or 40％) or absolute hypotension [mean arterial pressure (MAP) ＜ 50mmHg] were not significantly associated with postoperative delirium,nor was the duration of hypotension (MAP ＜ 50 mmHg).Conversely,intraoperative blood pressure variance was significantly associated with postoperative delirium.Conclusions These results showed that increased blood pressure fluctuation,not absolute or relative hypotension,was predictive of postoperative delirium.

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.
