民办高校大学生毕业实习的实然状态与应然诉求——以独立学院为例

毕业实习是实践教学的重要环节也是独立学院人才培养的重要组成部分.当前,独立学院毕业实习中存在着毕业实习质量监控不够全面、毕业实习指导教师精力有限、实习基地不稳定等一系列的问题.解决这些问题不仅需要"母体院校"的有效支持,更需要独立学院自身科学、合理、有效的安排毕业实习工作,独立学院要在思想上给予毕业实习工作足够的重视,在人力、财力上给予毕业实习工作足够的支持、在各项工作措施上要切实有效.     

浅谈小学语文个性化阅读教学

《语文课程标准》指出":阅读是学生的个性化行为,不应该以教师的分析代替学生的阅读实践,应让学生在主动积极的思维和情感活动中,加深理解和体验,有所感悟和思考,受到情感熏陶,获得思想启迪,受审美乐趣。"个性化阅读是新课标倡导的一种阅读取向,它是阅读本身的客观规律。一、搜集信息,自主阅读。新课标的教育理念,使人们认识到"语文的外延和生活的外延"相等,人们的视野开放了,观念更新了,从书本延     

哈尔滨市外商直接投资技术溢出效应分析

在哈尔滨市外商直接投资金额不断增长的背景下,外商直接投资技术溢出效益如何成为备受关注的问题。为了验证外商直接投资是否对哈尔滨市的经济发展存在技术溢出效应,分析哈尔滨市利用外商直接投资的基本特征,并运用1991—2009年的数据进行实证分析。回归分析结果说明哈尔滨市外商直接投资存在正的技术溢出效应,但该效应并不显著。认为可以通过改善外商直接投资的政策环境,提高外商直接投资规模,引导外商直接投资进入技术密集型行业等措施提高哈尔滨外商直接投资的技术溢出效应。     

Suppressing progress of pancreatitis through selective inhibition of NF-κB activation by using NAC

Objective: To explore the characteristics of NF-κB activation in the progress of pancreatitis, the relationship with expression of TNF-α in the inflammatory reaction, and prevent the exacerbation of pancreatitis by using NAC. Method: Forty-eight rats were divided into three groups: therapy (group C), pancreatitis (group B) and control (group A). NAC served as the inhibitor of NF-κB activation. In the time intervals of 1.5, 3.0, 6.0, 12.0 hour, NF-κB activation was detected with flow cytometry (FCM) and the expression of TNF-α mRNA and protein with in situ hybridization (ISH) and enzyme-linked immuno-sorbent assay (ELISA) respectively. Meanwhile, the level of lipase and amylase in the serum was assayed and the pathological change was evaluated. Result: NF-κB activation in the pancreatitis group was higher than that in the control group (P<0.01), peaked at 3 hours, and was depressed by the inhibitor of NF-κB, NAC. The expression of TNF-α as well as the level of lipase and amylase in the serum also rose synchronously with activation of NF-κB. In contrast to group A, it was significantly different (P<0.01) in group B. After using NAC in group C, all of these values were decreased and the inflammatory reaction in the pancreas abated evidently. The pathology changes of the pancreas were shown to be alleviated in group C. Conclusion: First, NF-κB activity is intensively initiated in the course of pancreatitis and shown to have closely relationship with the release of cytokines. Second, use of NAC markedly depressed NF-κB activation. TNF-α expression is down regulated by cytokines. It is suggested that NAC probably acts as a useful agent for treatment of pancreatitis by indirectly inhibiting activation of NF-κB.
