大众化进程中弱势高校资源短缺下的品质提升

弱势高校既是高校中的弱势群体，又是高等教育大众化的主要载体。弱势高校在大众化中迎来了历史性发展机遇，但同时又遇到了后续生源、师资、社会保障、社会关系和自然环境、人文等资源短缺性难题。使其品质提升难以为继，生存发展空间受阻，解决资源短缺困扰，需要社会、政府的支持和经济的发展、社会的进步，但从弱势高校自身来说，必须利用市场和计划，深化改革，更新办学理念，形成办学特色，提高教育质量，加强队伍建设和创新管理机制。     

试论高校图书馆如何服务好成教函授学生

成教函授学生与普通高校学生相比,有其自身的特点.他们更有必要利用图书馆,更需要图书馆的服务.因此,高校图书馆必须转变观念.更好地为成教函授学生服务.     

零部件质量不确定对其再制造加工的影响

针对零部件再加工路线与再加工时间的不确定性问题,建立了零部件再加工系统的开环排队网络模型.该模型考虑了再加工机器故障和有限缓冲能力,并假定机器故障率、维修率和再加工时间服从指数分布.基于分解原理和扩展方法,给出了求解模型的近似分析算法以求解零部件的平均再加工时间、再加工效率等系统参数.提出了零部件质量的标定方法,并以此...     

文化民族性与晚清高等教育演进

鸦片战争后,西方文明的冲击打乱了中国社会既有的发展秩序,晚清社会的政治、经济与文化等各个领域开始发生变革。由于文化历史与传统的原因,晚清的文化变革较为缓慢并带有鲜明的民族性特征。晚清文化民族性深刻地影响了晚清高等教育的演进。     

班级良好人际关系的创建

班级是学生成长生活的主要关系体,一个班级的良好人际关系包括师生关系、同学之间的关系、教师与家长的关系等。本论文主要从我国班级人际关系的现状入手,分析了现实班级人际关系存在的主要问题,并在此基础上探讨了如何创建班级良好人际关系。     

AsCl_3在9mol·L~(-1)盐酸一苯和水一苯相中分配比的测定

本文介绍了笔者设计的测定AsCL_3在9mol·L~(-1)盐酸—苯相的分配比(D_1)和在水—苯相中的分配比(D_2)的简便方法。试验测知,在19℃时,D_1为10.82,D2为0.0180。苯对9mol·L~(-1)盐酸中的As(Ⅲ)的萃取率为91.5％,水对苯相的As(Ⅲ)的反萃取率为98.2％(等体积一次萃取)。     

中小学教师继续教育现存的问题与解决策略研究

随着教育改革的逐步深入,从"双基"到"三维目标"再到"核心素养",教育正从知识本位向人本位逐渐迁移,时代的变迁对中小学教师提出了更高的要求。但是,现阶段我国的中小学教师继续教育仍然存在许多不足和问题,笔者认为,要使中小学教师继续教育真正发挥实效,必须增大教师继续教育资金的投入,邀请一线教学经验丰富的名师担任讲师,变更培训时间,构建继续教育评价机制,从而让中小学教师继续教育健康、科学、有序地开展。

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.
