Recently, there were many reports indicated that epinephrine nasal or scalp infiltration or endotracheal [...]
Objective: To discuss the trends about the phase value, T2* and R2* value of susceptibility weighted imaging (SWI) with the arterial oxygen level, and analyze the accuracy about the thrombus volume measurement using SWI.Methods: 12 cases of human arterial blood were collected. They were scanned using MR SWI according to 6 time point of 1,3,5,7,9,11 [...]

Objective The aim of present study is to investigate the morphologic characteristic of laryngeal arteriole, and to provide precise anatomic data for 3D radiotherapy of larynx neoplasms, laryngeal transplantation and laryngeal reconstruction. Methods 10 casting cadavers with intact laryngeal (named from 1 to 10 samples) were corroded by hydrochloric acid, the branches of laryngeal arteriole [...]
While people’s living standard has been improving, the dietary structure is out of balance and more fatty substance is absorbed. Consequently the incidence of coronary diseases has been rising. At present Percutaneous Transluminal Coronary Angioplasty (PTCA), a minimally invasive surgery, is one of the most popular therapies for the coronary diseases in China. As an [...]
Purpose:The aim of the study was to assess the effect of nebivolol on relaxation of captopril(10-8-3×10M) and losartan (10-7-3×10-4M) in spontaneously hypertensive rats (SHR) different arteries.Methods:SHR and age-matched Wister-Kyoto (WKY) rats were randomly divided into 3 groups：(1) SHR+Nebivolol:SHR treated with nebivolol(8 mg/kg/day, i.g.); (2) SHR control group (Vehicle once daily, i.g.); (3) WKY control group [...]
