《中小学图书馆(室)规程》十五年后的新使命及愿景

2018年中西部地区无机化学化工学术研讨会

作者： Xiaolu wang Leilei Xie Lifang Liu Wenming wang hongfei wang Key Laboratory of Chemical Biology and Molecular Engineering of Education Ministry Institute of Molecular Science Shanxi University Key Laboratory of Energy Conversion and Storage Materials of Shanxi Provence Institute of Molecular Science Shanxi University

In recent years, the discovery of nitric oxide（NO） as a signaling molecule in various physiological and pathological pathways has spurred research on the design of metal nitrosyl complexes with novel photo-induced reactivity and cellar biological activity [1–4]. In this work, nitrosylruthenium complexes using 8-hydroxyquinoline derivatives and amino acids as ligands were synthesized, and their photodynamic reactions were investigated. The photochemical DNA cleavage of the complexes was also demonstrated, possibly due to photo-induced free radicals. The crystal structures were determinated by X-ray diffraction, the photo-induced NO-release were confirmed through spin trapping of the electron paramagnetic resonance spectroscopy（EPR）, and the dynamic process of the NO dissociation upon photo irradiation was monitored using time-resolution and two-dimensional correlation infrared spectroscopy. The life time of the excited states for some complexes were measured and compared through super-fast absorption spectral technology. Furthermore, the binding constants of the complexes with calf thymus DNA and human serum albumin were calculated by fluorescence spectroscopy to understand the effects of the substituent groups on the biological activity. The DFT calculation were also performed to analyze and understand the photo induced the dissociation of the metal nitrosyl complexes. This provided the basis for design of NO-donors with potential applications in photodynamic therapy.

一、问题的提出现代社会,＂匠人精神＂相对于过去正在流失。很多老一代的工人可能都有这样的经历,在工厂里,老师傅对年轻徒弟＂传、帮、带＂,对很多细节问题做深入的讨论和研究。但是后来,因为各种原因,这种＂匠人＂的文化精神过时了,更多的是机械化制造,以及按部就班的工作。富士康更是把这种相对冷漠的生产方式推到极致,同一个工厂的工人相互不认识,缺乏交流。这种状态下,生产者绝对不会对产品产生任何感情。整体氛围如此,企业的最高层领导也不会花大量时间关注产品。对于企业管理者来说,肯定不会认为自己是个＂匠人＂,

Case Report An female infant patient, aged 8 months old, suffered from irregular colporrhagia for a period of 1 month after which she was taken to our hospital on 30th April, 2003. A pelvic CT examination displayed a 6.5 cm×3.0 cm shadow of a soft-tissue tumor growing longitudinally in her supravaginal uterine area （Fig. 1）. The density of the shadow was uneven, in which there were irregular low-density loci, an indication of a compression of the colon and bladder and a diffuse boundary between the posterior wall of the urinary bladder and tumor. No abnormalities were found in either kidney or ovary, the liver or gall bladder. Also no obvious lesions were seen on the chest X-ray film, and routine blood and urine laboratory examinations were normal.

化学变化的本质是化学键的形成与断裂。凝聚态化学的主要特征是分子内的物理与化学过程与周围环境之间的动态相互作用和动力学耦合,不仅会影响化学键形成与断裂的化学反应平衡与反应速率,还会改变化学反应的走向。动力学振动光谱技术是探测凝聚态体相中与表面上各种微观分子细节最为有力的当代谱学表征技术之一。与脉冲核磁技术类似,科学家们使用一组精心设计的激光脉冲在凝聚态体系中激发复杂的光学响应,所产生的信号中包含了比传统吸收光谱丰富得多的反应机理、分子与溶液结构、分子运动、电荷与能量传递等微观信息。近年来,各种动力学振动光谱被运用于凝聚态化学的各个领域,尤其是在溶液态和表界面态领域,获得了一系列突破性进展,并且处于不断发展的过程之中。在本文中,我们将回顾及展望动力学振动光谱技术的基本概念、实验方法和理论框架,以及它们在凝聚态及表面态化学中的重要应用。
