二分髌骨较罕见,系因青春期二个或多个髌骨骨化中心(化骨核)未融合而形成,临床误诊为骨折的屡有报道。为提高对二分髌骨影像征象的认识,避免法医学鉴定失误,现分析行法医学鉴定的3例二分髌骨资料并结合文献,阐述其形成原因、组织学变化、影像学征象及临床症状体征。3例被鉴定人均为成年,因膝关节外伤后出现膝部疼痛,曾被医疗单位诊断为髌骨骨折,委托损伤鉴定2例,伤残评定1例。依据Saupe’s分型法,其中Ⅲ型2例,Ⅱ型加Ⅲ型1例。在法医学鉴定实践中,熟知二分髌骨影像学征象并与髌骨骨折鉴别,可确保鉴定结论的客观、准确。 相似文献

This study examined perceptions of differential treatment relating to school disciplinary practices in a racially and ethnically diverse sample (Black, South Asian, Asian, White, and other racial/ethnic background) of high school students (N = 1870). Participants completed detailed individual questionnaires assessing general perceptions of school disciplinary practices and various aspects of the school environment. Results indicated that racial/ethnic minority students are much more likely than White students to perceive discrimination with respect to teacher treatment, school suspension, use of police by school authorities, and police treatment at school. Multivariate analyses revealed that such perceptions are particular strong for Black students. In addition, a number of other variables such as gender, socioeconomic status, age of immigration, and views of school climate also predicted students' perceptions of differential treatment toward members of their racial/ethnic group. The implications of these findings are discussed, and suggestions for future research are outlined. 相似文献

Lipomas are common benign tumors most frequently found within the subcutaneous areas of the body. Deep-seated lipomas are rare and tend to be larger than cutaneous ones. Lipomas are rarely seen in the thoracic cavity, and they are usually located in the mediastinum, bronchiole, and lungs. Diaphragmatic lipomas have been occasionally reported in the literature, the first being described by Clark et al. in 1886. The authors report two rare cases of giant diaphragmatic lipoma incidentally found during forensic autopsies. In the first case, a Caucasian 85-year-old woman burned to death with another passenger, after her methane-fueled car collided with another car on a highway near Terni, Umbria, Italy. In the second case, a Caucasian 45-year-old man collapsed while walking through the countryside of Perugia. In either case, a large mass in the thorax was observed. The definitive pathologic diagnosis was giant intrathoracic diaphragmatic lipoma without evidence of malignancy. The authors also review the relevant literature and discuss differential diagnoses. These case reports contribute to the establishment of the actual incidence of diaphragmatic lipomas. 相似文献

目的:筛选卵巢老化及针刺“肾俞”干预的相关基因。方法:建立自然的更年期大鼠模型,实验动物包括青年组、更年组、针刺组,采用mRNA差异显示PCR技术,筛选卵巢中差异表达的基因,其中部分进行克隆、测序,并与NCB I相关数据库进行同源性比较。结果:获得16条差异表达明显的cDNA片段,其中已测序的6条均为未知功能基因。结论:卵巢老化及针刺“肾俞”的干预效应可能是多基因参与作用的结果,对分离到的cDNA进一步研究有助于揭示其分子机制。 相似文献
