恣意纵横的东方气象 --近观赵无极的艺术世界

赵无极是一位融合中西方艺术精华的当代抽象主义绘画大家。他的独特的艺术风格的形成,源自于他对传统中国文化的彻悟与对西方现代艺术的借鉴。赵无极的艺术历程给我们剖析了东西方文化结构在相悖的情景下而得以戏剧性结合的秘密。他的成就为当代志在探索中西结合绘画道路的中国艺术家提供了一个借鉴的可能。

目的 :建立一种在临床上比较实用的GHb的测定方法。方法 :将Bio -Rex70阳离子交换树脂溶液与溶血液充分振荡、混匀后 ,离心 ,测定上清液的吸光度值。结果 :变异系数 :,正常标本CV % =3、3% ;高值标本CV % =4、5 %。方法比较 ,与泰康公司微柱法试剂盒比较r=0 .94 ,密切相关。灵敏度 ,0 .0 1A相当于GHb为 0 .3%。结论 :经改进的微柱法 ,简便、快速 ,性能符合临床要求     

试论文龙对《金瓶梅》主旨的解读

文龙对于《金瓶梅》的主旨有着独到的认识。在考虑《金瓶梅》是否是淫书时,其把思考的重心放在读者身上,认为读者的素质是理解《金瓶梅》是否是淫书的关键;他还结合自身生活体验来思考《金瓶梅》的“四贪”问题,认为深层次的快乐来源于心灵的自足而非欲望的满足。另外,他还指出《金瓶梅》是有慨于世事之作。     

3-(6-溴吡啶-2)-2-(2-氟-6-氯苯)-噻唑酮-4的电子结构与抗HIV活性间关系的量子化学研究

采用AM1方法,对3-(6-溴吡啶-2)-2-(2-氟-6-氯苯)-噻唑酮-4(BPFCTZO)进行了量子化学计算,给出了分子的几何构型、原子的净电荷、键级、前沿分子轨道组成与能级、前沿轨道电子密度等参数.结果表明BPFCTZO分子的稳定构型呈蝴蝶状,噻唑酮环为主活性区,其上的2位C、4位N和6位O等原子很可能是其与RT酶作用的活性位点.     

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.     

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.

INTRODUCTION Plants have defense mechanisms against patho-gen infection by inducing systemic resistance in re-sponse to localized pretreatment with biological cotrol agents, thus making them resistant to subsequpathogen infection (Caruso et al., 1999; Hammschmidt, 1999; Mohammadi and Kazemi, 2002; yada et al., 1995; Pozo et al., 2002; Ray et al., 199Biological control of plant pathogens has receivmuch more attention.
