早期心肌梗死死后诊断的法医病理学研究进展

心源性猝死在成人猝死的死因中占首位,心肌梗死是冠心病猝死的主要机制之一,由于早期心肌梗死发生突然,且可在短时间内死亡,肉眼和镜下都缺乏典型的形态学改变,一直都是法医实践中研究的热点,本文回顾多年来心肌梗死的研究成果在法医学中的应用及局限,展望新的临床指标在法医工作中的可行性,期望提高死后心肌梗死诊断的准确率。     

唐律之血亲规范与现代刑法关系研究

《唐律疏议》是中国古代法律的集大成者,对后代的立法产生了极其深远的影响.现行刑法与唐律疏议在时间上相差千年之久,但是却有着浓厚的渊源关系.从血亲规范角度比较二者,现行刑法与唐律血亲规范一脉相承,唐律血亲规范的重要历史作用和对我国现代刑法的深远意义.     

Genetic population data of 38 autosomal InDels for the Amerindian community Embera-Chami of Lapo,Antioquia-Colombia

This paper presents the genetic characterization of the Embera-Chami Amerindian community of Lapo-Antioquia-Colombia using 38 autosomal Indels. This group of markers showed a high discriminatory power (>99.9999%) and an appropriate power of exclusion (99.40%), allowing the use of these markers in the field of forensic genetics in this population.     

Genetic risk and the birth of the somatic individual

This paper considers the implications of the rise of the new molecular genetics for the ways in which we are governed and the ways in which we govern ourselves. Using examples of genetic screening and genetic discrimination in education, employment and insurance, and a case study of debates among those at risk of developing Huntington's Disease and their relatives, we suggest that some of the claims made by critics of these new developments are misplaced. While there are possibilities of genetic discrimination, the key event is the creation of the person 'genetically at risk'. But genetic risk does not imply resignation in the face of an implacable biological destiny: it induces new and active relations to oneself and one's future. In particular, it generates new forms of 'genetic responsibility', locating actually and potentially affected individuals within new communities of obligation and identification. Far from generating fatalism, the rewriting of personhood at a genetic level and its visualization through a 'molecular optic' transforms the relations between patient and expert in unexpected ways, and is linked to the development of novel 'life strategies', involving practices of choice, enterprise, self-actualization and prudence in relation to one's genetic make-up. Most generally, we suggest, the birth of the person 'genetically at risk' is part of a wider reshaping of personhood along somatic lines and a mutation in conceptions of life itself.     

武汉汉族群体3个多拷贝Y-STR基因座的遗传多态性

目的提供DYS385、DYS459和DYS464基因座的群体遗传学资料。方法用荧光标记引物及ABI 3100型基因分析仪对武汉地区176名汉族男性无关个体的DYS385、DYS459和DYS464 3个多拷贝Y-STR基因座进行分型。结果在DYS385和DYS459基因座的个体,可观察到1~2个不同长度的扩增产物;DYS464基因座个体,可观察到1~4个不同长度的扩增产物。DYS385基因座检出14个等位基因及47种单倍型,DYS459检出4个等位基因及7种单倍型,DYS464检出9个等位基因及51种单倍型,其单倍型多样性分别为0.9591、0.6047和0.9560。3个基因座构成的联合单倍型共有133种,其多样性值达0.9909。结论3个多拷贝Y-STR基因座均为高多态性的遗传标记,联合应用具有较高的个体分辨能力。     

Etiological Similarities Between Psychological and Physical Aggression in Intimate Relationships: A Behavioral Genetic Exploration

Previous research has consistently shown that there is a strong association between psychological and physical aggression in intimate relationships. Theories as to why this association exists include that they have a single underlying etiology with differing thresholds, or they have separate etiologies and there is a two-step process by which psychological aggression moves to physical. The current study suggests that these two theories are not necessarily competing theories. The genetic and environmental covariance between psychological and physical intimate partner aggression were examined in 134 monozygotic (MZ) and 41 dizygotic (DZ) twin pairs. Results showed that psychological and physical aggression have largely the same genetic etiology, and any differences between the two are a function of differing nonshared environmental influences.
