BACKGROUND： Research of transgene brings hope for gene therapy of various diseases; in addition, some projects have been tested in clinic. Recently, the focus has been to find an ideal vehicle and a suitable therapeutic gene. OBJECTIVE： To explore an effective way to construct recombinant adeno-associated viral vectors expression in human neurnnergen-3 gene. DESIGN： Gene directed cloning. SETTING： Central Laboratory of Northern China Coal Medical College. MATERIALS： DH5a competent bacillus coli strain was provided by Capital Medical University; pCDNA3-NT-3 by professor Chen from Bengbu Medical College; pAAV-Laze, pAAV-Helper, pAAV-RC and pAAV-MCS plasmids by Capital Medical University; HEK293 cells by Cell Center of Basic Medical College of Tongji Medical University. METHODS： NT-3 genes which were selected from pCDNA3-NT-3 plasmids were cloned in pAAV-MCS to form a recombinant adeno-associated viral plasmid （pAAV-NT-3）. pAAV-NT-3, pAAV-RC, pAAV-LacZ and pHelper plasmids were extracted, purified and subjected to enzyme-shearing evaluation. In addition, pAAV-NT-3 and pAAV-LacZ were cotransfected with pHelper and pAAV-RC, respectively into AVV-293 cells with DNA mediated by calcium superphosphate transfection gene; and then, AVV-293 cells were packed into recombinant adeno-associated viral rAAV-NT-3 and rAAV-LacZ. After collection of viral particles, rAAV-LacZ viral stock solution was diluted based on ratio of 10：1 and the mixture was used to infect HT 1080 cells. X-gal stain was used to measure virus titer. MAIN OUTCOME MEASURES： Size of targeted gene fragments, validity of vehicle construction and virus titer. RESULTS： Targeted gene NT-3 was successfully inserted into the relative vehicle pAAV and pAAV-NT-3 was correctly recongnized by enzyme-shearing evaluation. Enzyme-shearing electrophoresis demonstrated that pAAV-NT-3, pAAV-RC, pAAV-LacZ and pHelper plasmids were successfully extracted and purified. β-galactoside staining in situ indicated that LacZ genes were ex

The interaction of calf thymus DNA （CT DNA） and water-soluble manganese corrole, 5,10,15-tris（4-carboxyphenyl）corrolatomanganese（Ⅲ）（MnuTCPC） has been studied by absorption spectra, fluorescence spectra and CD spectra, as well as by viscosity measurements. Results revealed that this manganese corrole binds to CT DNA via an outside groove binding mode with intrinsic binding constant Ku of 4.67 × 104 Lomol L DNA cleavage activities of MnmTCPC in the presence of various oxidants were also investigated, MnmTCPC can cleave the supercoiled plas- mid pBR322 DNA to both nicked and linear form in the presence of hydrogen peroxide or tert-BuOOH, while no nuclease activity was observed by using KHSO5 as oxidant. Inhibitor tests revealed that hydroxyl radicals or singlet oxygen was not involved in MnTCPC mediated DNA oxidative cleavage. It is suggested that （oxo）manganese（V） corrole is the possibly active intermediate in this oxidative cleavage reactions.

Searching for highly efficient catalysts toward dehydrogenation of hydrazine for chemical hydrogen storage is highly desirable for the development of hydrogen economy. Herein, we report a simple in situ co-reduction synthesis of NiPt nanoparticles supported on CeO_2 nanospheres and their superior catalytic performance for hydrogen generation from alkaline solution of hydrazine at room temperature. Thanks to the strong electronic interaction arising from synergistic effect at atomic lever and support-metal interaction between NiPt and CeO_*** obtained Ni_5Pt_5-CeO_2 catalyst exhibits 100% hydrogen selectivity and superior catalytic performance for hydrogen generation from alkaline solution of hydrazine at room temperature, with a TOF value of 416 h 1.

With intensified contradiction between the rapid devel- opment of modem industry and the carrying capacity of natural environment, coordinating the relationship between economic benefits and ecological benefits is a significant issue to be solved for modem industrial engineering. This paper firstly conducts the comparative analysis between traditional and ecological industry as well as traditional and modem industrial engineering, and in- dicates that eco-industrial engineering is an inevitable choice for sustainable development of modem industrial engineering; Then, based on industrial ecology, environmental economics and sustain- able development theory, the connotation and definition of eco- industrial engineering are proposed, and the theoretical and practi- cal development of the concepts of eco-industrial engineering are further investigated. Furthermore, the research subject, research content, academic system architecture and evaluation methods of eco-industrial engineering are discussed. Finally, combining the current scientific and technological development, we put forward the important scientific value and practical significance of con- structing eco-industrial engineering for the utilization of these concepts.

随着多接收质谱仪分析技术的进步,铬稳定同位素体系在最近二十几年的环境科学和地球化学中得到了越来越广泛的应用。铬元素属于氧化还原敏感元素,在氧化还原反应过程中伴随着较大的同位素分馏。因此,铬同位素在指示现代或古代环境的氧化还原状态方面有着重要的应用。同时,铬也是中度相容和轻度亲铁元素,使得铬稳定同位素体系也可用来制约高温地质过程(如核幔分异、地幔熔融和岩浆分异结晶等)以及地外行星的演化。本综述首先介绍铬稳定同位素体系,随后讲述分析方法、铬同位素分馏原理以及铬同位素在高温、低温地球化学中的应用。

Tardive dystonia (TDt), a cluster of extrapyramidal symptoms that are caused by long-term use of antipsychotic medication, is characterized by difficulty in autonomic movements of skeletal (voluntary) muscles and consequent deformations of the body. TDt is rarely seen among patients taking olanzapine, but olanzapine was the precipitating antipsychotic medication in this 22-year old male patient with schizophrenia who developed lip puckering, persistent involuntary torticollis, muscular pain, axial dystonia and unstable gait after taking a standard dose of olanzapine regularly for about one year. His symptoms did not resolve after his olanzapine was stopped. Four months of treatment with clozapine combined with magnesium valproate, vitamin E, tiapride, and lorazepam did not lead to any improvement in the dystonia.
