利用尸食性蚤蝇推断死亡时间的法医学研究进展

死亡时间的准确推断一直是法医学的难题。昆虫学方法已被认为是死亡时间推断的有效方法。尸食性蝇类发育生物学在死亡时间推断中有着重要地位。蚤蝇体形微小,在相对密闭的空间,可成为尸体上主要的甚至是唯一的昆虫证据。本文从尸食性蚤蝇的作用、种属鉴定以及日龄推断方面,综述了利用尸食性蚤蝇推断死亡时间的法医学研究进展。     

椎弓崩裂与外伤伤病关系法医学鉴定26例分析

目的阐述椎弓崩裂与外伤之间伤病关系的法医学鉴定要点。方法收集26例椎弓崩裂案例,从年龄、伴随症状、治疗方式、致伤方式等方面讨论此类病例的特点。结果认定外伤与损伤后果之间存在一定因果关系的2例被鉴定人年龄均在50岁以下,致伤方式均为高能量损伤,且均伴有合并伤,2例患者均接受了手术治疗。结论应关注50岁以下中青年外伤后椎弓崩裂与外伤之间的伤病关系分析。对于选择手术治疗者,更需分析两者之间的伤病关系。     

磁性纳米颗粒在法医学痕量分析中的应用进展

鉴于法医学痕量分析中生物样本的复杂性以及目标物的痕量性,需要一种简单有效的方法从复杂基质中获得足量的目标物。磁性纳米颗粒(magnetic nanoparticle,MNP)凭借其独特的超顺磁性、稳定的物理化学性质、生物相容性、尺寸小、较高的比表面积等特性,已在生物医药、药物递送和药物分离等多个研究领域显现出广泛的应用价值。为了将MNP应用于法医检材的前处理,最大程度地增加目标物的提取率,尽可能减少干扰因素以满足目标物痕量分析要求,本文综述了近年来MNP在法医毒物分析、环境法医学、痕量物证分析和刑事侦查领域的应用进展,为MNP在法医学痕量分析中的应用提供研究思路。     

法医学尸体检验职业防护指南(建议稿)

法医工作者的职业暴露风险极大,案件现场及尸体上的有毒有害物质、高致病性微生物以及利器、骨折等因素均可能给法医带来身心伤害甚至生命危险。随着经济社会发展,法医的工作环境已经较过去显著改善,但是针对个人防护的重视程度仍需提高。近年来公共卫生事件频发,给法医职业防护带来新的挑战,迫切需要借鉴生物安全领域的先进技术和防护理念,以满足新形势下法医工作的需要。本指南立足当前法医职业防护的实际需求,从暴露风险、防护分级、应急处置等角度阐述,希望能为制定法医职业防护相关标准提供参考,以指导法医工作者开展个人防护工作,为提升法医职业化水平和身心健康提供帮助。     

Professionalizing Arts Management in Healthcare Facilities

An urgent need exists for trained specialists to manage organizational policies and practices involving arts programs and activities in healthcare facilities. This article introduces the field of arts in health and argues for what is currently needed within the academic and professional field of arts management to advance this emerging arena of arts management theory and practice. The authors integrate key references from existing scholarship alongside additional survey data to offer recommendations for developing professional management of the arts in healthcare facilities like hospitals, hospices, and long-term care centers. The article provides an overview of the responsibilities of arts managers in healthcare institutions, as well as insight into the knowledge, competencies, and skills that arts managers require to effectively work in these settings. The article concludes with articulating a conceptual framework for a long-term research trajectory to inform further advancement of this distinct sub-field of arts management.     

Diagnosing Crime and Diagnosing Disease: Bias Reduction Strategies in the Forensic and Clinical Sciences

Cognitive effort is an essential part of both forensic and clinical decision‐making. Errors occur in both fields because the cognitive process is complex and prone to bias. We performed a selective review of full‐text English language literature on cognitive bias leading to diagnostic and forensic errors. Earlier work (1970–2000) concentrated on classifying and raising bias awareness. Recently (2000–2016), the emphasis has shifted toward strategies for “debiasing.” While the forensic sciences have focused on the control of misleading contextual cues, clinical debiasing efforts have relied on checklists and hypothetical scenarios. No single generally applicable and effective bias reduction strategy has emerged so far. Generalized attempts at bias elimination have not been particularly successful. It is time to shift focus to the study of errors within specific domains, and how to best communicate uncertainty in order to improve decision making on the part of both the expert and the trier‐of‐fact.     

视盘RNFL厚度改变与视野缺损的关系

目的探讨视网膜神经纤维层厚度与视野的关系及其在司法鉴定中的应用。方法采用GDx VCC和Octopus自动视野计对外伤视神经病变52例进行检查。按照视野有效值分组(组1-重伤组,组2-轻伤组,组3-轻微伤及以下组),统计其平均RNFL厚度,对各组的RNFL厚度进行方差分析;同时对平均RNFL厚度与视野指数(MD、MS、sLV)、视野有效值进行相关性及回归分析。结果组1的RNFL平均值36.300±8.456 95μm,组2的RNFL平均值53.647 4±15.453 06μm,组3的RNFL平均值60.903 6±9.535 14μm。通过方差分析,组1~3各组间差异显著,各组两两相比较差异显著。平均RNFL厚度与视野有效值、MS呈正相关(r=0.543、0.400,P0.05),平均RNFL厚度与MD、sLV呈负相关(r=-0.450、-0.440,P0.05)。平均RNFL厚度与视野有效值、MD、MS、sLV的直线回归方程分别为Y=0.967X+19.508、Y=0.095X-10.858、Y=0.175X+9.187、Y=-0.205X+20.215;二次项方程分别为Y=-0.037X~2+5.208X-93.795、Y=0.010X~2-1.325X+50.111、Y=-0.008X~2+1.103X-15.606、Y=0.004X~2-0.520X+22.232。结论 RNFL厚度检测具有客观评定视野的法医学价值,有望成为评估视野的一种客观、形态学新方法。
