Video-assisted thoracoscopic surgery （VATS） for bilateral primary spontaneous pneumothorax

Objective:To review our experience of the treatment of bilateral primary spontaneous pneumothorax (PSP) by video-assisted thoracoscopic surgery (VATS). Materials and methods: Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results: Twelve males and one female, with age ranging from 15 to 36 years (mean 23.1 years), were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously (n=4) or sequentially (n=9). The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients (84.6%) had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was (45.6±18.3) min (range 25-96 min) and (120.6±28.7) min (range 84-166 min) respectively for the non-simultaneous (second VATS for the recurrence of contralateral side after first VATS) and simultaneous (bilateral VATS in one operation) procedures. There was no postoperative mortality. However, prolonged air leakage (>7 d) occurred in one patient (7.7%) who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions: VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior side.

面向就业的美国职业群课程模式探析

美国职业群课程模式以经济发展和就业需求为本，旨在培养学生的就业弹性和职业适应能力。实现其终身职业生涯发展。它以职业群分类和职业途径为依据，构建有序的课程体系。在实施过程中注重为学生制定系统的学习计划、加强职业指导服务和广泛建立合作伙伴，并逐渐开展了基于职业技能标准的课程评估。当前，职业群课程模式在联邦和州政府的管理和支持下得到了普及和推广，但也存在一些亟待克服的困难和问题。     

On-line estimation of concentration parameters in fermentation processes

INTRODUCTION Saccharomycete, closely linked with human life, is the only microbe that has been utilized to the extent of over a million tons in the world, and is one of the modelled biological bacteria mostly used in modern genetic engineering. Since there are no effective online instruments for measuring the production or resultant concentration, which is a very important quality index in fermentation process, soft sensors (Martin, 1997; Tham et al., 1991; Assis and Filho, 2000; Salgad…

中国美术中的审美特色

中国美术的审美特色是在漫长的岁月中形成的,它是和中国人的哲学观紧密相连的.这个审美特色缘起于诸子百家时期,在以后的发展和形成过程中又吸收了大量的外来思想,在各种思想的共同作用下逐渐定型,并在我国封建时代中到达了高峰.近代西学的进入给传统的审美思想带来了强劲的冲击,但百年的中西文化碰撞还没能让中国的审美特色发生质的变化,中国画的审美精神仍然是立足于中国人的哲学思想,发生变化的只是具体的技法.     

浙江"特色产业"论

特色经济的核心是特色产业。浙江的特色产业有着独特的发展思路和发展模式；它推动了浙江经济发展、富裕了浙江人民、使浙江快速完成了资本积累；它发挥了浙江优势、调整优化了浙江农村产业、产品结构，以鲜明的特色开辟了浙江独特的市场空间，避免产业趋同和不合理的重复建设；最终形成了与特色产业相配套的龙头企业和专业市场，带动周围地区加工生产进一步发展，提高了浙江农业工业化、集约化程度。这是浙江成为全国经济明星的成本。
