体外培养FBs损伤模型的建立及细胞免疫组化研究

首次应用培养人胎肺成纤维细胞 (FBs)损伤模型 ,体外研究创缘FBs合成细胞型纤维连接蛋白 (cellu larfibronectins,cFn)的变化与损伤时间的关系。结果表明 ,损伤使处于静息状态的融合FBs成为具有运动能力和增殖能力的活跃细胞。应用免疫组化ABC法结合图像分析技术 ,观察伤后不同时间创缘FBs内cFn的含量变化。伤后 1h ,可以检测到cFn有变化 ,且在伤后 6h内 ,cFn逐渐增多 ,其变化与损伤时间呈正相关。这对今后应用cFn与损伤时间推断的研究提供了科学依据 ,同时为法医学损伤时间研究开辟了新的途径。     

“My Kids,They Safe.”: Lived Experiences of Parents Receiving Child Neglect Allegations

Abstract

This study aims to explore parents’ lived experiences of receiving child neglect allegations and how they make sense of these experiences. The sample consists of parents who participated in a family preservation program following allegations of child neglect. Semi-structured interviews were conducted and analyzed using interpretative phenomenological analysis (IPA). The findings suggest that parents resist neglect allegations, both by denial and minimization, partly due to their lack of clear understanding of what constitutes child neglect. Further, parents in this study tended to be reactive to meanings ascribed to the label of child neglect rather than the allegations per se. They seemed to experience internal conflict between their positive evaluations of their own parenting and what their neglect allegations might imply about their parenting. Parents also experienced emotional distress, such as concern about social stigma and fear of losing their parental rights, as they tried to make sense of their current situations. Suggested implications for practice include exploring parents’ subjective understanding of their allegations and considering their unique familial and sociocultural contexts from the outset of their involvement with child protective services (CPS) in order to build a collaborative working alliance.     

School-related victimizations among adolescents: An analysis of National Crime Survey (NCS) narratives

This paper uses a heretofore untapped source of information in the National Crime Survey (NCS) victimization data—the interviewer narratives—to explore school-related victimizations among adolescents. These narrative reports provide important information bearing on lifestyle and routine activity theories of victimization that is simply not available from the more familiar, highly structured portions of the NCS questionnaire. The NCS narratives suggest that a large proportion of school-related victimizations stems from peer interactions that occur in the course of routine daily activities and escalate into victimizations. Students represent pools of both potential offenders and potential victims who come in frequent contact with each other, often in the absence of capable guardians. However, rather than predatory, calculated attempts to harm, school-related victimizations among adolescents appear to consist primarily of bullying, injured pride, and misguided mischief. The theoretical and methodological implications of this study are highlighted.     

传染性腔上囊病病毒HN01超强毒株VP2基因的克隆和序列分析

根据GenBank中登录的传染性腔上囊病病毒(IBDV)标准强毒株52-70株基因组序列,设计并合成了1对扩增IBDV VP2基因的特异性引物.以IBDV超强毒分离株HN01感染发病鸡腔上囊组织中提取的病毒RNA为模板,用RT-PCR扩增出了1.45 kb的cDNA产物,将扩增的IBDV HN01株VP2基因克隆于pMD 18-T载体上,获得了pMD 18-T-VP2重组质粒.将IBDV HN01株 VP2基因序列测定结果与已发表的其他IBDV毒株VP2基因序列进行分析比较,绘出系统进化树.结果表明,HN01株与欧洲超强毒株UK661、日本超强毒株OKYM、香港超强毒株HK46等非常相似,而与经典强毒株、弱毒株和变异株相差较大.     

南宋初期美学思潮的重大转折

"靖康之难",北宋灭亡。"建炎南渡"初期,历史出现巨变,其爱国主义、民族主义热情高涨,由此产生了区别于前代的时代特点。曾经因为党禁的政治因素遭到贬抑的苏轼词风却大盛于建炎,是有其深刻背景的。当时美学思潮出现重大转折,在词这一文学审美样式上得到集中体现,改变了人们对其审美功能的体认,即由抒情转为言志,由浅斟低唱转为壮怀激烈,一直影响了整个南宋的文学审美历程。在这一转折过程中,军人岳飞所作的词具有不可忽视的地位。     

新文学史：社会文化思潮与历史变革的双重叠影

仅仅以“回归文学本体”的视野考察中国新文学史的构成 ,是难以揭示其本真面貌的 ,只有与“社会—历史批评”模式相结合 ,方可认清新文学史的个性主义、民族主义和马克思主义三大社会文化思潮与多次历史变革双重叠影的复杂结构形态。

"相关市场"界定的困惑与解析

在反垄断法上,"相关市场"的界定往往是展开竞争分析的出发点和前提.为了使其界定的结果更加符合实际情况,各国的执法机构在实践中纷纷引入经济分析的方法,并且总结出了许多界定的规则,但是由于经济生活的极度复杂性,使得这一界定过程充满了不确定的因素.加之考虑到司法成本的投入和法官素质要求过高等限制性条件,要想精确地界定"相关市场"的边界便显得十分困难.
