Sex differences in suicidal ideation in a community sample from China

In a large sample of over 4,000 Chinese residents in the Wuling and Sino-Vietnamese border regions of China, females had a higher incidence of ever wishing that they were dead. This sex difference was found regardless of marital status, age, and occupation.     

Identifying sex chromosome abnormalities in forensic DNA testing using amelogenin and sex chromosome short tandem repeats

Forensic DNA laboratories worldwide have begun using multiplexed STR systems to decrease analysis time and increase sample throughput. The loci used in these systems are basically "nonsense" regions of human DNA. However, due to the chromosome on which some of these loci are located, various genetic abnormalities can sometimes be detected. This paper will show one such abnormality--Klinefelter's Syndrome--and the process used to show the possibility of this defect in two undiagnosed males using peak height ratios at the Amelogenin locus, and X-Y STRs.     

Craniometry and mathematical calculations as a method for viscero-cranium profile determination

The aim of this work is to prove the application of craniometry in determining the identity of unknown bodies. There is a great correlation between the viscero-cranium appearance and the osseous structure, the said correlation following mathematical rules and thus being possible to be calculated. Various segments of the skull and different size of the angles they make with each other are directly responsible for the graphic profile of viscero-cranium. The nasal bones and their angle are the basis to determine the shape and size of the nose.     

大鼠脑挫伤后FN表达与损伤时程关系的研究

为寻找推断脑损伤经历时间的可靠指标,采用自制自由落体撞击法致大鼠右顶叶局灶性脑挫伤模型,于不同时间段处死大鼠后,进行纤维连接蛋白的免疫组织化学及原位杂交法研究,结果发现纤维连接蛋白及其 mRNA表达水平与伤后经历时间有一定相关性,并能较好地鉴别死前脑挫伤和死后脑挫伤,可作为推断脑挫伤经历时间的参考指标之一。     

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。     

骨骼种属鉴定的组织学研究

目的 探求骨骼残渣的种属鉴定的组织学方法。方法 对人体不同部位骨骼,及常见动物骨骼的 77张骨组织学切片,在光镜下进行了骨组织学形态学研究。结果 不同动物骨组织学的形态学特征存在明显差异,其主要差别有：内、外环骨板的形态和相对厚度;哈氏系统之间的骨板的形态和哈氏系统的大小;哈氏环层骨板的数量及骨陷窝的数量等。结论 骨组织学的特征,不仅可以区分人与动物骨骼的残渣,也可以对不同动物的骨骼残渣进行区分。
