民办高校教学质量管理探析

民办高等教育作为我国教育体系的重要组成部分,在人才培养过程中发挥着巨大的作用。民办高校只有提高教学质量,才能从真正意义上提高学校竞争力,在生存和发展中立于不败之地。学生状况、师资情况、专业和课程设置、教学评价与监控体系等因素是影响教学质量的主要因素,抓好这几个方面是保证民办高校教学质量提高的关键。     

国外大学的入学制度与特殊政策

本文对美国、英国、法国、德国等几个国，在大学入学考试制度、入学条件、录取方法，以及对能力发展显著学生的特殊政策等问题进行了阐述，以期对我国大学入学制度的改革提供借鉴。     

多元智能理论视野下的创造力培养

加德纳在对传统智力理论进行批评的基础上，提出了多元智能理论。多元智能理论从“解决问题与创造产品”的角度出发对智力进行新的诠释，由此提出了创造力具有多元性的观点，这对素质教育背景下的创造力培养具有重要的启示意义。     

汉康液的抗氧化作用及对SOD活力的影响

小鼠给予汉康液2.0g/kg/日,连续灌胃22天,结果表明该液能明显降低小鼠血清中丙二醛(MDA)含量,并对血清超氧化物歧化酶(SOD)活性有显著增强作用。     

对国库集中收付制度下的财政监督机制的探讨

党的十六届六中全会提出的“全面努力地构建和谐社会”是我们近期工作、学习的指导思想。国家财政作为重要的财力保障，在构建和谐社会的伟大工程中担负着致力于市场机制和谐、经济运行和谐、社会发展和谐的重要使命，这就客观上要求政府必须强化财政监督，以确保国家财政致力于和谐社会建设目标的全面实现。所以，建立健全财政监督机制，对加强财政监督具有重要的现实意义。本文针对在国库集中收付制度下如何建立健全财政监督机制做了简单的探讨。     

师生冲突的概念界定与分类探究——基于刘易斯·科塞的冲突分类理论

论文通过借鉴和辨析社会学理论中的冲突概念,对师生冲突概念作出界定。根据美国当代社会学家刘易斯·科塞的冲突分类理论,对学校师生冲突进行分类研究。在此基础上提出了三个观点:学校师生冲突的多数属于非现实性冲突;师生结构由紧密走向松散是师生冲突增多的重要原因;师生冲突具有一定的正面功能。     

突出"课程"要素保障教学质量——华威大学教学质量内部保障体系研究

华威大学是一所在短时间内迅速崛起的新大学,它的成功与其教学质量内部保障体系关系密切.本文在对华威大学教学质量保障体系的目标、组织构架、保障方法等进行分析的基础上,总结出其教学质量保障体系的几个突出特点:切合实际的质量目标、高效的组织结构、紧紧围绕"课程"保障教学质量的方法,并将这种突出强调"课程"要素的质量保障体系归纳为"课程型"质量保障模式.     

短小芽孢杆菌β-内酰胺酶基因的克隆

以质粒pSC101为载体,用鸟枪法将短小芽孢杆菌A3染色体的β—内酰胺酶基因,克隆至大肠杆菌HB101。经质粒检测及酶切电泳分析证明,克隆的β—内酰胺酶基因位于2.6kb的EcoRI片段上,将此片段连接到质粒PAL32转化枯草杆菌,亦能表达并向胞外分泌β—内酰胺酶。     

五四小说中知识分子形象的类型及其价值趋向

五四时期知识分子小说的人物形象,鲜明地体现出孤独、彷徨、虚无的情绪特征,使小说带上了强烈的抒情、感伤的色彩.在小说的人物系列划分上具有类型化的倾向,同时,每一类人物又显示出各自的价值趋向.五四知识分子小说及其人物形象普遍呈现出"时代精神"与"时代情感"的矛盾冲突.     

Investigation on apoptosis of neuronal cells induced by Amyloid beta-Protein

Objective: To construct a PC12 cell strain with neuronal differentiation, and observe the apoptosis and pro-liferation activity effects induced these cells by Amyloid beta-Protein (Aβ-43). Methods: 1) PC12 cells in logarithmicgrowth phase were subcultured for 24 h. After the culture fluid was changed, the cells were treated with Rat-β-NGF andcultured for 9 days. 2) Neuronal differentiation of PC12 cells in logarithmic growth phase were divided into four groups:control group (0), experimental group (1), experimental group (2) and experimental group (3). The concentrations of Aβ inthe four groups were 0 μmol/L, 1.25 μ mol/L, 2.5 μ mol/L and 5 μmol/L, respectively. The cells were harvested at 24, 48 and72 h later and stained with AnnexinV-FITC/PI after centrifugation and washing. Then flow cytometry was conducted toexamine the apoptosis percentage. 3) NGF-induced PC12 cells were selected and Aβ with different concentrations wasadded. The final concentrations of Aβ were 0 μmol/L, 1.25 μmol/L, 2.5 μmol/L and 5 μ mol/L, respectively. After the cellswere incubated in an atmosphere of 5% CO2 at 37 ℃ in an incubator for 72 h, the OD values were examined. Results: 1)Neuronal differentiated PC 12 cell lines were successfully established. 2) Flow cytometric examination indicated that Aβ(1.25, 2.5, and 5.0 μmol/L) could effectively induce apoptosis of neuronal-differented cells at the 24 h, 48 h and 72 h timepoints. 3) Aβ (0-5.00 μ mol/L) had no obvious effect on proliferation or restraining of the neuronal differentiation of thePC 12 cells after a 72 h interacting process. Conclusion: This investigation revealed successful neuronal differentiation of thePC12 cell strain. The induction of apoptosis of the neurocytes by various concentrations of Aβ was observed and the in-fluence of Aβ on induced proliferation of PC 12 cells by Rat-β-NGF was revealed. This study -05 provide basis for futureresearch on the molecular cure of AD and interdiction of AD evolution.
