校友捐赠对高校发展的作用及影响因素探析

伴随着我国经济持续、健康发展,我国高校校友捐赠数额快速增长,已逐渐成为高校办学经费的重要资金来源.文章从改善高校财务状况、促进高校学术自由和增强校友凝聚力等三个方面,分析了校友捐赠对高校发展的积极作用;从校友、学校、社会环境与文化背景、政策与法律制度等四个角度,分析了影响高校校友捐赠的因素.作为校友捐赠的受益主体,高校应加强校友会组织与管理工作,健全和创新校友会的组织体系,加大校友捐赠的宣传力度,营造校友捐赠文化氛围,以吸引更多的校友捐赠.     

应用型本科：《操作系统》课程讲授思路的研究

目前各个高校的计算机专业都开设有操作系统课程,操作系统的应用已从单一的计算机发展到如智能终端等其它更多的领域,其结构也从最初的监督程序发展到现在的可大、可小、可裁剪的多重结构,其算法、接口、界面等都在发生变化。百变之中,操作系统的基本工作原理是不变的。所以,应用型本科的计算机操作系统课程的教学,在讲授思路上将以操作系统的核心作为讲授重点,以学生熟知的＂程序＂为切入点,以期取得好的教学效果。

依托“创先争优”活动 建立大学生党员评议机制

根据"创先争优"活动的有关要求,结合高校在大学生党员培养、教育和管理等方面普遍关注的重要环节,建立大学生党员评议机制,主要从大学生党员的理论修养、政治追求、学业成绩、社会实践、党务工作、遵纪守法、群众认可度等方面进行定性定量的评议和分析,进而为建立健全大学生党员保持先进性的长效机制提供有效的依据。     

基于向量空间模型的古汉语词义自动消歧研究

借鉴现代汉语词义消歧的研究成果,提出一种改进的向量空间模型词义消歧方法,即在古汉语义项词语知识库的支持下,将待消歧多义词上下文与多义词的义项映射到向量空间模型中,完成语义消歧任务。以中国农业古籍全文数据库为统计语料,对10个典型古汉语多义词,共29个义项、1 836条待消歧上下文进行义项标注的实验,消歧平均正确率达到79.5%。     

Induced pluripotent stem cells: origins, applications, and future perspectives

Embryonic stem(ES)cells are widely used for different purposes,including gene targeting,cell therapy,tissue repair,organ regeneration,and so on.However,studies and applications of ES cells are hindered by ethical issues regarding cell sources.To circumvent ethical disputes,great efforts have been taken to generate ES cell-like cells,which are not derived from the inner cell mass of blastocyst-stage embryos.In 2006,Yamanaka et al.first reprogrammed mouse embryonic fibroblasts into ES cell-like cells called induced pluripotent stem(iPS)cells.About one year later,Yamanaka et al.and Thomson et al.independently reprogrammed human somatic cells into iPS cells.Since the first generation of iPS cells,they have now been derived from quite a few different kinds of cell types.In particular,the use of peripheral blood facilitates research on iPS cells because of safety,easy availability,and plenty of cell sources.Now iPS cells have been used for cell therapy,disease modeling,and drug discovery.In this review,we describe the generations,applications,potential issues,and future perspectives of iPS cells.     

关于中高职衔接问题的探讨

目前,我国中职升高职缺乏直接升学渠道,高职出现招生难现象,制约中高职的进一步发展。建立中职与高职的有效衔接,是职业教育体系完善和提高职业教育质量的关键,即拓宽中职毕业生继续学习的通道,又增强职业教育的吸引力。从中高职衔接的现实意义入手,分析中高职不衔接的主要表现,进而进行相应的对策研究。     

Influence of serum adiponectin level and SNP +45 polymorphism of adiponectin gene on myocardial fibrosis

Adiponectin plays an important role in the development of hypertension, atherosclerosis, and cardiomyocyte hypertrophy, but very little was known about the influence of serum adiponectin or the adiponectin gene polymorphism on myocardial fibrosis. Our study investigates the influence of the SNP +45 polymorphism of the adiponectin gene and serum levels of adiponectin on myocardial fibrosis in patients with essential hypertension. A case-control study was conducted on 165 hypertensive patients and 126 normotensive healthy controls. The genotypes of adiponectin gene polymorphisms were detected by the polymerase chain reaction (PCR) method. Serum concentrations of procollagen were measured by a double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in all subjects. The integrated backscatter score (IBS) was measured in the left ventricular myocardium using echocardiography. The serum levels of adiponectin in hypertensive patients were significantly lower than those in the normal control group ((2.69±1.0) μg/ml vs. (4.21±2.89) μg/ml, respectively, P<0.001). The serum levels of type-I procollagen carboxyl end peptide (PICP) and type-III procollagen ammonia cardinal extremity peptide (PIIINP) in the hypertension group were significantly higher than those in the control group. In the hypertension group, serum levels of adiponectin were significantly and negatively related to the average acoustic intensity and corrected acoustic intensity of the myocardium (r=0.46 and 0.61, respectively, P<0.05 for both). The serum levels of PICP and PIIINP were significantly different among the three genotypes of SNP +45 (P<0.01). Logistic regression analyses showed that sex and genotype (GG+GT) were the major risk factors of myocardial fibrosis in hypertensive patients (OR=5.343 and 3.278, respectively, P<0.05). These data suggest that lower levels of adiponectin and SNP +45 polymorphism of the adiponectin gene are likely to play an important role in myocardial fibrosis in hypertensive patients.
