从城市发展的理性角度看植物景观规划格局的构建

植物景观作为生态文明背景下城市规划中的重要介质,越来越为行业重视。本文在传统园林植物理法的基础上,站在城市发展的角度观察植物景观对于城市景观、城市生态结构所起的作用,并结合近几年植物景观在规划中的问题提出植物景观规划格局要理性构建的论点。通过分析城市硬质结构、城市生态结构、场地等潜在的逻辑需要,论述植物景观规划必须重视逻辑性。通过植物景观内在、外在自然秩序,社会秩序的梳理阐述了植物景观规划格局构建必须尊重合理的秩序。对植物景观规划格局构建的科学性思考可以满足现代城市景观中植物规划的艺术性与生态稳定性要求。

Research on the Development of Drug Regulatory Science in China

Objective To study the situation of the development of China’s drug regulatory science and to provide some suggestions for its future development.Methods Based on the origin of regulatory science in China,the methods of literature research and comparison were used to make a detailed analysis of China’s drug regulatory science plan and its implementation effect,the research direction,the number of key laboratories,regulatory science exchange conferences and professional papers published,so as to put forward the development trend of China’s regulatory science.Results and Conclusion According to China’s national conditions,the government should continue to promote the development of the regulatory science system from three aspects:basic theoretical research,discipline construction and action plan.China’s drug regulatory science can not only promote the rapid development of pharmaceutical industry,but also guarantee public health.

Apolipoprotein E mimetic peptide protects against diffuse brain injury

Apolipoprotein E plays a crucial role in inhibiting chronic neurodegenerative processes. Howev-er, its impact on neurological function following diffuse brain injury is still unclear. This study was designed to evaluate the therapeutic effects and mechanisms of action of apolipoprotein E mimetic peptide on diffuse brain injury. Apolipoprotein E mimetic peptide was administered into the caudal vein of rats with diffuse brain injury before and after injury. We found that apo-lipoprotein E mimetic peptide signiifcantly decreased the number of apoptotic neurons, reduced extracellular signal-regulated kinase1/2 phosphorylation, down-regulated Bax and cytochrome c expression, decreased malondialdehyde content, and increased superoxide dismutase activity in a dose-dependent manner. These experimental ifndings demonstrate that apolipoprotein E mimetic peptide improves learning and memory function and protects against diffuse brain injury-induced apoptosis by inhibiting the extracellular signal-regulated kinase1/2-Bax mito-chondrial apoptotic pathway.

论计划生育“三结合”模式的科学性

计划生育“三结合”由吉林省率先提出近十年，并已被国家充分肯定。十年来的实践已证实了计划生育“三结合”的正确与可行，尚缺少理论上的深入研究，经在国家计生委立项的“计划生育三结合之路研究”的软课题中找到了计划生育三结合提出的理论依据，进一步论证了计划生育三结合的科学性。
