创缘周围血管生成在皮肤损伤时间推断中的应用

皮肤损伤时间推断一直以来都是法医病理学者所需解决的重要问题,免疫组织化学技术具有方便、敏感的特性,它的应用大大提高了皮肤损伤时间推断研究的发展。然而,有效指标的缺乏却限制了免疫组织化学技术的应用。血管生成在皮肤损伤愈合过程中发挥着非常重要的作用,因此,血管生成相关因子可能在皮肤损伤时间推断方面具有重要价值。

刑事政策视野下的未成年人刑事检察程序

为了更好地保护未成年人的合法权益,在未成年人刑事检查程序中体现“宽严相济”的刑事政策,贯彻教育挽救、区别对待的原则,不仅应当在实体上体现对未成年人“宽严相济”,在程序上也应当体现“宽严相济”,达到“教育、感化、挽救”失足未成年人的目的。     

关于审判工作机制改革的思考

现行的审判工作机制行政色彩浓厚 ,存在着诸多弊端。建立独立、公平的审判工作机制 ,主要的措施是要全面推行审判长和独任审判员选任制度 ,按照责任原则 ,落实合议庭及独任审判员负责制 ,强化合议庭和法官责任。     

刑事责任年龄认定存在的问题及对策研究

由于立法上缺乏刑事责任年龄认定标准;司法实践中户籍资料、被告人供述和辩解、证人陈述和骨龄鉴定认定依据均存在问题;刑事证据采纳标准和司法成本影响刑事责任年龄的认定,从而导致犯罪嫌疑人尤其是未成年人刑事责任年龄的认定处于不确定状态。对此,立法上应明确规定认定刑事责任年龄的法律依据;司法实践中,严格户籍管理,适当运用骨龄鉴定,严格遵守证据的采信规则,合理规划司法成本。

Cross-national comparison of homicide: Age/sex-adjusted rates using the 1980 U.S. homicide experience as a standard

Cross-sectional studies of crime have typically relied on crude crime rates when making comparisons between countries. Crude rates control for population size but implicitly assume that all members of the population are equally at risk. Empirical studies have shown that, cross-nationally, risk varies by age and sex. Standardization of crime rates removes the confounding effects of variable age and sex population distributions. Since age/sex-specific crime rates are generally unavailable for many countries, the method of indirect standardization is the most desirable technique. Age/sex-adjusted homicide rates for 76 countries are presented, and two comparative measures are suggested. It is shown that while the United States has a higher homicide rate than all but 15 countries; in most cases, the magnitude of the difference, not controlling for age/sex differences, is overestimated. Crude rates underestimate differences between the United States and countries with higher rates of homicide.     

两种骨龄标准推断女性14岁年龄的准确度

目的研究李果珍百分计数法和中国人手腕骨发育标准CHN法在推断女性14岁年龄时的准确度。方法在湖南娄底三所中学随机选择51名14岁女生,同一条件下拍摄左手腕X线片;按照上述两种方法由专业人员阅片;对比两种方法所得结果及其与真实年龄间的差异。结果计数法和CHN法测得的骨龄与研究对象的实际年龄间无显著性差异(P>0.05),两种方法比较也未见明显差异(P>0.05)。结论计数法和CNH法可用于湖南地区女性14岁年龄的推断。     

Histological age prediction from the femur in a contemporary Dutch sample. The decrease of nonremodeled bone in the anterior cortex

This paper presents an uncomplicated and minimally invasive method for age-at-death determination in a contemporary Dutch (West European) population, by modifying the approach of assessment based on the age-related remodeling of bone tissue. In contrast to the usual "osteon count," a "non-remodeled tissue count" is undertaken. To optimize the method, proper zeroing of the polarization filter set of the microscope is essential. Instructions for setting the filters are given. A sample of femoral shaft segments totaling 162 individuals with ages ranging from 15 to 96 years is analyzed. Subperiosteal quantitative assessments are recorded at the most anterior point of the femoral shaft and also at points 25 degrees to the left and to the right of that point. Interobserver agreement in the assessments shows an acceptable degree of correlation. Bone remodeling with age does not progress in a linear, but in a curvilinear manner. Dependence of predicted age on nonremodeled surface counts in the analyzed areas of the anterior cortex of the femur appears to be significant. A set of regression equations is given. Sex can be ignored in age prediction. The small but statistically significant dependence of predicted age on cadaver length corresponds with the present strong secular increase in stature in the Netherlands. A concise catalogue with micrograph examples for every 10-year period in life is available upon request.     

A quantitative method for estimation of volume changes in arachnoid foveae with age

Age-related changes of arachnoid foveae have been described, but objective, quantitative analyses are lacking. A new quantitative method is presented for estimation of change in total volume of arachnoid foveae with age. The pilot sample consisted of nine skulls from the Palmer Anatomy Laboratory. Arachnoid foveae were filled with sand, which was extracted using a vacuum pump. Mass was determined with an analytical balance and converted to volume. A reliability analysis was performed using intraclass correlation coefficients. The method was found to be highly reliable (intraobserver ICC = 0.9935, interobserver ICC = 0.9878). The relationship between total volume and age was then examined in a sample of 63 males of accurately known age from the Hamann-Todd collection. Linear regression analysis revealed no statistically significant relationship between total volume and age, or foveae frequency and age (alpha = 0.05). Development of arachnoid foveae may be influenced by health factors, which could limit its usefulness in aging.
