关于娱乐型游泳池的设计

室内游泳池是其必备的硬件设施,娱乐型游泳池工艺简单也比较成熟,因而常被设计所轻视,国内许多宾馆游泳池虽然采用了先进的进口设备,但由于忽视了众多的细节问题,使用效果并不理想。一般的情况是:结构及加热部分由国内设计单位完成,工艺设计与设备供应由国内代理商承揽,又分土建、安装、装饰三家施工。容易产生问题。

Ultrasound ablation of pulmonary veins for treatment of paroxysmal atrial fibrillation

Objective: to evaluate the efficacy and safety of ultrasound ablation of pulmonary veins for treatment of paroxysmal atrial fibrillation. Methods: The study population consisted of 9 patients with 5 males and 4 females enrolled consecutively who had idiopathic paroxysmal atrial fibrillation(AF). The ultrasound balloon was positioned through a special sheath to the orifice of the target vein by a transseptal procedure. The balloon was inflated with contrast-mixed saline (contrast: saline = 1:4) whose volume was decided by the diameter of the target pulmonary vein. The ablation energy was usually set up at 35 to 40 watts with temperature controlled at 60℃. The duration of each ablation was about 120 seconds which was repeated not over 10 times. Results: The average duration of the total procedure was 132±68 min for our patients. The average fluoroscopy time was 33±17 min. With a mean follow-up of 16±8 months after the procedure, AF was completely eliminated in 4 patients without antiarrhythmic drugs. The episodes of atrial fibrillation were eliminated in 2 patients with low dosage of oral amiodarone (0.1, once daily) which was ineffective before the procedure. The frequency of episodes was similar to that before the procedure in 3 patients. There were no complications such as hemopericardium, air embolism and stenosis of the pulmonary veins by angiography, related to the procedure. Conclusion: Ultrasound ablation of the pulmonary veins is a new approach to treat paroxysmal atrial fibrillation. Before we determined its value, we need to do more researches with bigger sample, randomization and comparison design.

“讲授法”的自述

我是“讲授法”。在教学中,长期以来我控制了整个课堂,老师们教学向来都离不开我。可自从新一轮课程改革的到来, “探究法”、“尝试法”风光地登上了教学舞台,我也就倍受冷落了。不仅受冷落,有的书刊还公开批
