纤维蛋白原在心肌梗死死后诊断的特异性研究

为探讨纤维蛋白原(Fg)在心肌梗死死后诊断的特异性,应用免疫组织化学和图像分析技术,对正常心脏、心肌梗死及其它非梗死性的引起直接或间接心脏损害的情况如心肌炎、窒息、电击死、出血性休克、心挫伤、有机磷中毒等心肌细胞内Fg的变化进行研究。结果发现:正常对照组心肌细胞内未见Fg阳性反应,而心肌梗死、心肌炎、窒息、电击、休克、心挫伤、有机磷中毒等组均可见Fg阳性反应,且各组Fg阳性反应面积与正常对照组存在显著性差异。因此Fg作为心肌梗死死后诊断指标,易受心肌炎、窒息、电击、休克、心挫伤、有机磷中毒等的影响,对诊断心肌梗死的特异性较差。     

溺死大鼠肺组织水通道蛋白1的表达

目的检测生前溺死与死后抛尸的肺组织水通道蛋白的表达。方法取2种死亡方式条件下大鼠肺组织,用免疫组织化学方法检测肺组织中水通道蛋白1表达的分布特征。结果两种死亡条件下肺泡间质和支气管周围的毛细血管内皮及肺泡上皮均有AQP1的阳性表达,但积分光密度值(intergratedopticaldensity,IOD)值有显著性差别。结论AQP1在大鼠两种溺死条件下表达差别有统计学意义。     

液压冲击脑损伤后细胞间粘附分子表达的研究

目的测定外伤性脑损伤后脑内细胞间粘附分子(ICAM-1)的变化。方法用大鼠液压冲击脑损伤致伤模型制作大鼠脑损伤,伤后2、4、8、12、24h取脑组织,用免疫组织化学方法染色并用MIAS图像分析系统进行图像分析。结果脑损伤后2h即可见ICAM-1在脑内表达上调,12h达高峰,24h已回落。结论测定I-CAM-1在脑内的变化情况,可为推断24h以内脑损伤形成时间及伤后存活时间提供参考。     

浅谈公安院校课堂教学的现状及对策

本文是根据自己多年的公安教学实践写成的。在课堂教学中,深切体会到目前公安院校课堂教学的诸多弊端:教学方法单一;部分教师的教学囿于教材面上的内容;在传授知识的过程中,忽视学生能力的培养等等。针对上述问题,提出应全面提高公安院校师资队伍素质;改革教学方法和手段;改革教学内容和课程体系等对策。     

Feminism, Aestheticism and the Limits of Law

This article seeks to identify and address the normative void that resides at the heart of postmodernist-feminist theory, and to propose a philosophical framework – beyond postmodernism, but incorporating its central insights – for thinking through the normative questions with which feminists are inevitably confronted in their engagements with positive law. Two varieties of postmodernist-feminism are identified and critically analysed: the ‘corporeal feminism’ of Elizabeth Grosz and Judith Butler, which seeks to ground feminist critical practice in the irruptive capacities of the material body considered as an arte fact of social construction; and the deconstructionist feminism of Drucilla Cornell, for whom ‘the feminine’ is an indeterminate but disruptive force beyond its construction in law and in other social sites. The first component of the argument elaborated here is that each of these approaches ultimately reduces to a form of aestheticism which is incapable of generating a worthwhile and workable feminist approach to the restructuring of politics and law. The second component of the argument involves a return to aesthetics, in particular to the philosophical aesthetics of Kant’s Critique of Judgement. Kant’s aesthetic philosophy, it will be suggested, yields a framework of concepts which, duly re-manipulated, could speak to the very concerns that have inspired postmodernist-feminism: how to attend to (bodily) particularity while avoiding the dangers associated with ‘essentialism’; and how to theorise the propensity of the unrepresentable power of the feminine to exceed both embodied human capacities and the confining rein of socially privileged rationalities. Crucially, however it also responds to a set of preoccupations – those of the feminist lawyer – that cannot be accommodated by postmodernism: how to translate embodied experience into (legal) norms; generalise from the particular; seek consensus; and codify an endless potentiality in the form of law.

家兔角膜上皮和内皮细胞DNA含量与PMI关系的图像分析

目的 探讨家兔角膜上皮和内皮细胞DNA含量与PMI的关系。方法 应用计算机图像分析技术,测定105只家兔死后72h内不同时间点家兔角膜上皮和内皮细胞核DNA含量(IOD)的变化值并做统计学分析。结果 家兔死后72h内其角膜上皮细胞和内皮细胞核DNA降解速率与PMI具有显著的相关性,并由此归纳出体现DNA降解趋势的二项式回归方程。结论 应用计算机图像分析技术,测量机体死后角膜内外皮细胞DNA含量变化,将会成为推断PMI精确、客观的新方法。     

对树立警察公共关系理念的思考

当前,全国公安机关正在开展“贯彻十六大,全面建小康,公安怎么办”大讨论活动,本文试图通过对公安队伍建设的研究,对适应新形势,倡导警察公共关系理念进行分析,对警察行为和功能在公众中的心理影响、传播沟通的地位和作用,以及警察良好形象的树立等问题进行深入的阐述。     

Labour Party: saved by the modernisers or modernised to be saved?

The paper treats politics as a complex process that embraces actual or potential interactions among constructed meanings of different social actors through various symbolic forms drawing on the specific socio‐historical, political context. These symbolic forms can take the form of various kinds from everyday linguistic utterances to complex images and texts. It is suggested that there is a strong interrelationship between ‘image’ and political discourse and their symbolic value grows as long as they come from consistent communication among all the social actors participating in the political process inside and outside of the political organisation. Two historical examples from the British political landscape—the Labour election defeat in 1987 and the Labour leadership election in 1994—are examined so as to draw some useful remarks concerning the limitations in drawing the line between ‘image’ and political discourse and among processes considered either internal or external of the party.

基于DCT变换的半脆弱水印研究

分析当前基于DCT变换的半脆弱水印算法,针对DCT变换后的系数,采用一种更简单的量化方法:直接用一参数对要嵌入的地方进行量化,其他非嵌入区保持系数不变.通过大量实验证明,该方法对一定程度的JPEG压缩具有好的鲁棒性,对滤波、噪声以及恶意剪切等攻击有好的脆弱性,为实际应用提供了好的思路.     

在路上:客家人的族群意象和文化建构

长期以来,人们对客家人的族群意象一直停留在静态的文化特质描述之上,而从人类学过程论和过程分析的角度,可得出客家人“在路上”的族群意象。其概指客家族群在历史长河中迁徙、抗争、发展的整个过程,将客家的历史、现在和未来一并纳入研究视野,涵括客家的历史渊源、形成过程、文化特质以及族群性格和精神特征。“在路上”的客家意象是一个过程,是一个阶段,是一种状态,是受历史框架、社会结构和文化心理形塑的历史记忆和文化书写。
