家兔死后眼玻璃体液锌、镍含量与 PMI关系的研究

目的寻找一种精确推定PMI的方法。方法应用电感耦合等离子体质谱（ICP－MS）,检测了家兔死后96小时内眼玻璃体液锌、镍元素含量,探讨其与PMI的相关性。结果家兔死后24h内眼玻璃体液锌、镍元素含量与PMI显著相关,可作为推定早期PMI的参考指标,其二项式回归方程分别为y=0.1404x2－1.3351x＋3.8298（R2=0.9202）、y=0.0043x2－0.0596x＋0.2665（R2=0.9103）。结论家兔眼玻璃体液中Zn、Ni元素含量变化是推定早期PMI的参考指标之一。     

唾液酯酶多态性在个体识别中的应用研究

目的 探讨唾液酯酶（ Set）多态性在法医学亲权鉴定和个体识别方面的应用价值。方法 应用聚丙烯酰胺凝胶盘状电泳及固蓝 RR染色方法,调查了 114名中国人 Set的表型分布及基因频率,用χ 2检验进行统计学分析。结果 中国人酯酶表型频率 Set F 22.81％, Set FS 50.88％, Set S 26.31％ ;基因频率为 SetF 0.482 5, SetS 0.517 5;非父排除机率为 0.187 5,个体识别率为 0.619 9。结论 Set有较高的父权排除率和个体识别率,可作为法医学亲权鉴定和个体识别的重要标记系统之一。     

精神分裂症病人肇事因素分析

就鉴定案例中肇事精神分裂症病人与一般精神分裂症群体、其他肇事精神病人群体的资料进行比较,结果显示：精神分裂症群体的肇事率、凶杀率远高于其他精神病群体;肇事精神分裂症病人的诊治情况明显差于一般精神分裂症群体,且再婚率低,家庭支持系统不力等。提示：加强对精神分裂症病人的社会监管和治疗,是防止肇事行为发生,维护社会治安的积极措施。     

The SEM observation of brain tissues and vascular corrosion cast of closed diffuse brain injuries

The morphologic changes of the closed injured brain of rats were observed by SEM. The rats either died immediately after conclusive injuries or were killed after 5 minutes to 5 days after injuries. The main changes were as follows: the diffuse disorder, twist, wave-like distortion and break of neuron fibers; axonal swelling; formation of axonal retraction balls; stripping and denotation of myelin sheath The ball-like swelling of neuron, break of neuron membrane and vascular wall, and microthrombus formations were also observed. These damages worsened with prolongation of surviving time of the rats. The axonal retraction ball appeared 8 hours after the injury and was approximately 3-5 cm in diameter, and developed to 7-8 cm after 3-5 days. It is observed that frontal lobe, cerebellum and brain stem were severely damaged.     

青少年犯罪预防理论的研究视角：从犯罪原因到犯罪断念的转向

断念是行为主体(特别是青少年越轨者或犯罪人)在一段稳定的时期内对犯罪偏好明显与确定的拒绝。现阶段犯罪预防措施通过控制青少年犯罪原因遏制青少年犯罪增长趋势,绩效前景颇为黯淡。从聚焦于犯罪原因分析到致力于犯罪断念研究的战略性转向将成为当代社会犯罪预防的重要突破。作为人生状态与行为过程的犯罪断念,在静态结构与动态运行的结合中发挥青少年犯罪预防的积极效果。     

Age estimation from the structure of adult human teeth: review of the literature.

The literature on age estimation from the structure of adult human teeth is reviewed. Several anatomic changes of teeth have been shown to be valuable in age determination, but there is still controversy concerning the accuracy of cemental annulation. It is believed that improvements in age estimation can be made using direct measurement rather than scoring systems.     

Endogenous bargaining power and the theory of small group collective choice

Contrary to some criticism (Musgrave and Musgrave, and West) the small group collective choice model may yield a determinate, Pareto optimal solution even with all or none bargaining. Such bargaining as well as the solution are implied by the basic assumptions of the theoretical model.     

A pathological study of sudden coronary death in China: report of 89 autopsy cases.

This paper reports the results of a forensic pathological study of 89 autopsy cases of Sudden Coronary Death (SCD). Of 89 cases, 63 (52 male, 11 female) were narrowed by 76-100% in cross-sectional area (XSA) of the coronary artery (CA) and 26 (22 male, 4 female), by 51-75%. Atherosclerotic plaques in the CA were serious and extensive, especially in the left anterior descending and often involved several branches of CA at the same time. Recent thrombosis was found in 18 cases, haemorrhage in plaques in 17 cases. Only 2 cases had visible acute myocardial infarction. Inflammatory cell infiltration was found in coronary plaques in 36 cases. Myocardial fibrosis or small scar formation was detected in 51 cases. It is suggested that although the incidence of coronary heart disease (CHD) is low in China, SCD is the commonest mode of Sudden Unexpected Death. The majority of SCD (52%) were middle aged males (30-49 years old). Most of the cases died suddenly during sleep without any clear precipitating factors. The characteristics of occurrence and pathological changes in the CA and myocardium and the pathological diagnosis of SCD are also analysed and discussed.     

Autopsy findings in the eyes of fourteen fatally abused children

The eyes of fourteen fatally abused children and sixteen control cases were examined histopathologically. Ten of the abused children showed intraocular change. The most common ocular changes were subdural hemorrhage of the optic nerve and retinal hemorrhage which involved all the layers of the retina, but most commonly the nerve fiber layer, ganglion cell layer and inner nuclear layer. The presence of blood cavities within the retina partially supported the hypothesis of traumatic retinoschisis. The control cases of non-abused children rarely showed intraocular hemorrhage.
