居住区景观美学分析

美是人类生活的永恒主题,居住区景观之美是居民高层次的需求,通过对居民景观整体和各要素的合理组构,使其具有完整、和谐、连续、丰富的特点。居住景观之美能潜移默化地更新人的观念、提高人的修养、提升人的品质、培养人的情操,这是创造优美居住景观的更高追求。在当今城市的发展中,现代设计美学的不断渗透使得居住区景观设计越来越体现出它的重要性,这需要设计者具有强烈的责任感,营造人与土地、人与自然和谐的人居环境;需要环境设计者本着对历史、社会和人负责的态度把握时代特性,不断探寻居住区景观设计的新理念与新方法。     

E26 Transformation-Specific-1 (ETS1) and WDFY Family Member 4 (WDFY4) Polymorphisms in Chinese Patients with Rheumatoid Arthritis

E26 transformation-specific-1 (ETS1) and WDFY family member 4 (WDFY4) are closely related with systemic lupus erythematosus. We hypothesized that ETS1 and WDFY4 polymorphisms may contribute to rheumatoid arthritis (RA) susceptibility. We studied ETS1 rs1128334 G/A and WDFY4 rs7097397 A/G gene polymorphisms in 329 patients with RA and 697 controls in a Chinese population. Genotyping was done using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. When the WDFY4 rs7097397 AA homozygote genotype was used as the reference group, the AG genotype was associated with a significantly increased risk for RA. In the dominant model, when the WDFY4 rs7097397 AA homozygote genotype was used as the reference group, the AG/GG genotypes were associated with a significant increased susceptibility to RA. In stratification analyses, a significantly increased risk for RA associated with the WDFY4 rs7097397 AG genotype was evident among female patients, younger patients, C-reactive protein (CRP) negative patients and both anti-cyclic citrullinated peptide antibody (ACPA) positive patients and negative patients compared with the WDFY4 rs7097397 AA genotype. These findings suggested that WDFY4 rs7097397 A/G may be associated with the risk of RA, especially among younger, female patients, CRP-negative patients and both ACPA positive and negative patients. However, our results were obtained from a moderate-sized sample, and therefore this is a preliminary conclusion. To confirm these findings, validation by a larger study from a more diverse ethnic population is needed.

建筑师的城市总体规划 大巴黎规划中建筑师的作用和贡献

在中国,建筑师对城市总体规划编制是陌生的。但在近年法国《巴黎大区总体规划2030》编制的过程中,却一直可以看到建筑师的身影。继2008年"大巴黎计划国际咨询"后,14支由建筑师领衔的多学科团队借助"大巴黎国际工作坊"这一平台,继续用各自独特的视角和分析方法,为未来大都市地区的建设勾勒出直观易懂而且打动人心的发展图景。文章拟借此重新提起建筑师如何参与城市规划工作的讨论,并通过大巴黎规划这个具体案例,说明建筑师参与规划可能发挥的积极作用及带来的贡献。

改变即日常——阿科米星的实践综述

在快速城市化背景下实践的中国建筑师是否可能从纷繁复杂的日常城市和建筑中发现建筑学的新经验？这正是阿科米星最近相关实践和研究的动力。本文指出工作室对日常的关注同一贯的工作立场、出发点、思考方式和价值观念有关,是一个逐步延续和转变的过程。日常建筑中蕴含的使用调整、有效建造和时间差异感的力量被尝试转化为具体的实践策略。改变即日常,自然而恒久。在中国社会不确定的语境中探索建筑学还能做什么意味着开放的边界和更多的可能。
