Early Repolarization,Acute Emotional Stress and Sudden Death

We herein report the case of a 36‐year‐old man who died suddenly after a fight with another man. Forensic investigations included unenhanced computed tomography, postmortem angiography, autopsy, histology, neuropathology, toxicology, and biochemistry and allowed a traumatic cause of death to be excluded. An electrocardiogram recorded some years prior to death revealed the presence of an early repolarization pattern. Based on the results of all investigations, the cause of death was determined to be cardiac arrhythmia and cardiac arrest during an emotionally stressful event associated with physical assault. Direct third party involvement, however, was excluded, and the manner of death was listed as natural. The case was not pursued any further by the public prosecutor.     

The Forensic Implications of Turner's Syndrome

Turner's syndrome, the most common sex chromosome disorder of females, is caused by complete or partial loss of one X chromosome and is associated with a wide range of internal and external manifestations and increased mortality rates (three to nine times the background population). While individuals with Turner's syndrome may survive for many decades, premature and unexpected deaths can occur that bring decedents to the attention of forensic examiners. Causes of death in Turner's syndrome are often linked to underlying cardiovascular conditions such as aortic dissection, congenital cardiovascular disease, ischemic heart, and cerebrovascular disease, but deaths due to noncardiac causes also occur with increased frequency. The latter include epilepsy, diabetes mellitus, chronic renal disease, pneumonia, chronic liver disease, and malignancy. Thus, the autopsy evaluation of these cases requires careful examination of all major organ systems, with the consideration of confirmatory cytogenetic testing.     

大鼠脑、骨髓细胞核DNA降解推断死后间隔时间的研究

目的检测大鼠死后不同温度下脑、骨髓细胞核DNA降解规律，寻找推断早期死亡间隔时间（PMI）的新参数。方法10℃和20℃下，大鼠死后0～40h内，每隔4h取材脑组织和骨髓，单细胞凝胶电泳（SCGE）检测DNA降解程度，线性回归分析比较彗星参数HeadDNA％、尾长（TL）、Olive尾矩（TM）与PMI的关系。结果大鼠死后早期脑细胞、骨髓细胞核Head DNA％随着PMI逐渐下降的程度不同，20℃脑细胞核Head DNA％降解速率较快。与骨髓细胞相比，脑细胞核Head DNA％与PMI线性关系较好。与TL、TM相比，Head DNA％与PMI的线性关系较好。结论脑组织是利用SCGE检测DNA降解推断PMI的合适检材。Head DNA％较TL、TM推断PMI的价值更高。     

心肌缺血早期表达蛋白的质谱研究

目的用SELDI-TOFMS观察大鼠急性心肌缺血后心肌蛋白质谱的变化规律,筛选心肌缺血的蛋白标记物,为法医学心源性猝死的诊断提供依据。方法SD大鼠分成手术组,假手术组和非手术对照组。在结扎大鼠冠脉前降支后5min～6h内不同的时间段取大鼠心肌组织。蛋白提取后用CM10芯片结合SELDI-TOFMS质谱仪检测。结果血清CM10芯片检测到3个缺血后蛋白峰,质荷比(m/z)分别为6304Da、8337Da、8375Da,在手术组中阳性率和特异性均为100%,假手术组和非手术组中均没有发现。特异性升高的峰有3个:峰6658Da、6876Da,都是在实验组中≥15min以后升高2倍以上,8577Da峰则在缺血≥5min组升高。结论大鼠心肌组织中6304Da、8337Da、8375Da蛋白峰都是急性心肌缺血后的较为特异性改变,可在心肌缺血后5min内出现,有可能做为心肌缺血的蛋白标记,亦可能用于心肌缺血和法医学心源性猝死的诊断。     

UNDERSTANDING THE INFLUENCE OF VICTIM GENDER IN DEATH PENALTY CASES: THE IMPORTANCE OF VICTIM RACE,SEX‐RELATED VICTIMIZATION,AND JURY DECISION MAKING*

Using data from the Baldus, Woodworth, and Pulaski (1990) study of Georgia's death penalty system, we examine the influence of victim gender in death penalty cases. Furthermore, to improve our understanding of the meaning of victim gender, we consider 1) the joint effects of victim gender and victim race, 2) victimization characteristics that might explain victim gender effects, and 3) the impact of victim gender at different decision‐making stages in the death penalty case process. We find that both victim gender and race are associated with death sentencing outcomes and that an examination of the joint effects of victim gender and race reveals considerable differences in the likelihood of receiving a death sentence between the most disparate victim race–gender groups. In particular, it seems that black male victim cases are set apart from all others in terms of leniency afforded to defendants. We also show that the effect of victim gender is explained largely by gender differences in the sexual nature of some homicides. An examination of prosecutorial and jury decision making reveals that although victim gender has little impact on prosecutorial decisions, it has a meaningful impact on jury decisions.     

医疗纠纷中135例猝死分析

目的为探讨引起医疗纠纷案例中猝死发生的特点，特别是其年龄、性别、科室、疾病的分布和发生纠纷的原因，为有关单位调处医疗纠纷和制定有关法规提供科学依据。方法自本教研室1955～1996年42a间受理的法医病理学尸检资料中挑选各种医疗纠纷案例；制定统一表格，将其中猝死者逐一登记，并进行统计分析。结果42a中涉及医疗纠纷的淬死135例。其中男87例、女48例。年龄自新生儿～67岁。以新生儿和婴儿居多（67例），男明显多于女；其次为25～34岁的青壮年组（21例），女多于男。近12a发生的猝死（94例）是过去30a（41例）的2．3倍。猝死疾病以呼吸系统最常见（46％），次为心血管系统疾病（25％）；但54例成人猝死者心血管系统疾病占首位（26例），次为泌尿生殖系统疾病（12例）。发生的科室多见于产科和儿科（74例）。结论认为近10年来医疗纠纷中猝死案例明显增多；医疗纠纷中非医疗事故远多于医疗事故；法医病理尸检对正确、合理地调处医疗纠纷，并对探讨猝死的发生机制，反馈、丰富和发展相关临床学科的内容，以及提高诊治水平均具有重要意义。     

对我国死刑制度的理性思考

我国刑法中的死刑制度在社会主义初级阶段,有保留的必要性;我国的死刑政策,是现阶段社会主义法制建设的能动反映,我国刑法中对死刑作了严格的限制性规定。随着我国经济的发展、法制建设的日益完善,死刑也终将被废除。     

冠心病猝死冠状动脉粥样硬化斑块病理形态学观察

目的观察冠心病猝死(SCD)和对照组心冠状动脉(CA)粥样硬化斑块的差异,探讨其在SCD中的意义。方法从本教研室2001年~2003年尸检档案中挑选64例有严重CA粥样硬化病变的病例及心脏标本,分SCD组(36例)和对照组(28例冠心病非猝死者)。除常规检查心脏外,重点检查CA左主干(LM)、左前降支(LAD)、左旋支(LC)和右主支(RM)的开口、类型、走向及粥样硬化斑块情况。每支CA分近、中、远3段,检测每个斑块距开口的距离、狭窄程度、长度、数目和形状(分偏心、环形、偏心+环形三种)。用SPSS11.5统计软件进行统计分析。结果SCD组中CA粥样硬化病变4级21例,3级15例;对照组4级12例,3级16例。两组斑块病变的严重程度无显著性差异(P>0.05)。SCD组粥样斑块长(x-2.0365 cm)、以CA近段较多、与CA开口或分支处的距离近(x-0.7457 cm);对照组斑块短(x-1.4283 cm)、以中段多见,与CA开口或分叉处的距离远(x-2.1942 cm);两组斑块的长度和距开口的距离均有非常显著性差异(P<0.01)。两组间斑块的形状在LAD和RM有显著性差异(P<0.05),而LM和LC则无(P>0.05)。结论SCD与冠心病非猝死者的CA粥样硬化斑块在部位、长度、形状和距CA开口的距离存在差异,而狭窄程度无差异。这对SCD的病理诊断和法医学鉴定具有十分重要的意义。     

被害人有过错的故意杀人罪的死刑裁量研究——从被害与加害的关系切入

故意杀人罪是最典型的有被害人的犯罪。被害人加害在先引起他人加害 ,或被害人激化矛盾引起他人加害属于被害人有过错的故意杀人罪。在故意杀人罪死刑裁量中 ,被害人的过错是酌定从轻处罚情节。司法解释确立了“被害人一方有明显过错或对矛盾激化负有直接责任的故意杀人罪 ,一般不应判处死刑立即执行”的规则 ,但在司法实践中对被告人量刑时往往不予考虑。为了减少和限制故意杀人罪的死刑适用 ,在立法上有必要将被害人的过错这一酌定情节法定化。     

不能犯未遂构成特征新论

不能犯研究的重心是确立不能犯未遂的成立条件与不可罚的不能犯相区别。传统的刑法理论关于不能犯未遂的研究存在误区。对于不能犯未遂的成立条件应从以下几点来分析:客观上行为具有法益侵害的相称性;主观上具有犯罪故意及犯意指向的明确性;不完全具备《刑法分则》规定的全部构成要件;行为人对事实存在认识错误。
