湖北省禽白血病自然病例的病理学诊断及p53和Bcl-2基因表达情况的观察

应用组织病理学和SABC免疫组织化学技术,对湖北省武汉市的2批14日龄和33日龄疑似禽白血病肉鸡进行了病理学诊断,并观察了病鸡肝肿瘤组织中p53基因和Bcl-2基因的表达情况。剖检可见病鸡肝、肾、脾均不同程度肿胀,组织病理学检查在肝、肾、心等脏器可见散在或聚集成团的骨髓瘤细胞,胞浆内充满球形的嗜酸性颗粒;在病鸡肝肿瘤组织中p53和Bcl-2基因均呈阳性表达,诊断为J亚群禽白血病(ALV-J),提示p53基因和Bcl-2基因与肉鸡J亚群禽白血病有关。     

骨折鉴定中MSCT及图像后处理的诊断与应用

目的探讨多层螺旋CT(MSCT)及其图像后处理功能在骨折法医鉴定中的诊断与应用价值。方法对366例法医鉴定者行薄层扫描并进行表面遮盖成像(SSD),透明化X线模拟投影(see-through)和多平面重建(MPR)处理。对所得图像进行诊断和分型。结果准确诊断并对134例鼻骨、98例眼眶和21例颅骨骨折进行分型。正确显示36例肋骨骨折、4例肩胛骨骨折、24例脊柱骨折和27例四肢骨及关节骨折。利用透明化X线模拟投影等技术鉴别陈旧性骨折18例。结论MSCT及图像后处理在骨折法医鉴定中具有重要实用价值,可为伤害等级鉴定提供有力的法医学依据。     

羊水栓塞诊断的方法学研究进展及法医学意义

羊水栓塞(amniotic fluid embolism,AFE)是指分娩过程中羊水进入母血循环,引起肺栓塞、休克甚至死亡等一系列严重症状的综合征。目前对于AFE的诊断为排除性诊断,方法缺乏灵敏性和特异性。因此随着以AFE为死因的孕产妇病死率的升高,寻找更精确的AFE诊断方法成为了法医学研究的重点。本文结合相关文献概述了AFE诊断方法的研究进展,希望能为法医学鉴定提供方法学参考。     

Unusual and Fatal Case of an Undiagnosed Intravascular Large B-cell Lymphoma: The Oncologist’s Great Imitator†

Intravascular lymphoma (IVL) is a rare subtype of extranodal lymphomas that is characterized by the selective growth of neoplastic cells within the lumen of small vessels. Authors document the case of an unexpected death caused by an undiagnosed intravascular large B-cell lymphoma with multi-organ involvement, which had initially manifested as an infection and then as an unclarified central nervous system pathology. Histological examination showed a diffuse intravascular large B-cell brain lymphoma with prominent cerebral involvement. The relevance of the case report reveals the importance of an autopsy of an extremely rare and threatening pathology that in most cases is diagnosed only postmortem. As a result, the role of the forensic pathologist becomes particularly important. When specifically performing an in-depth autopsy evaluation with a specific histologic analysis, it is possible to identify the intravascular lymphoma and declare a more accurate cause of death.     

120例闭合性颅脑损伤的临床诊断与法医鉴定的结论差异分析

有关闭合性颅脑损伤的临床诊断与法医鉴定的结论往往存在着差异,在脑震荡和脑损伤后综合症诊断上,这种差异尤为突出。差异的形成主要缘于临床诊断:临床医生过分依赖主诉;自信、草率、违反医理;对病人辅助检查不够;易受社会和人为因素干扰。     

Reliability of Sexually Violent Predator Civil Commitment Criteria in Florida

The present study investigated the reliability of Sexually Violent Predator (SVP) civil commitment criteria under Florida's Jimmy Ryce Act. The purpose of the study was to determine if, independently, 2 evaluators would reach the same conclusions about the same client (n = 295). According to civil commitment criteria outlined by the United States Supreme Court (Kansas v. Hendricks, 1997), SVPs must display a mental abnormality predisposing them to sexual violence and a likelihood of future sexual violence. The interrater reliability of 8 DSM-IV diagnoses applied by evaluators to determine whether a client has a "mental abnormality that predisposes him to sexual violence" was found to be poor to fair (kappa = .23 to . 70). The interrater reliability of risk assessment instruments used to determine "likelihood of reoffense" was good (ICC = .77 to .85). The recommendations made by evaluators regarding whether or not to refer a client for civil commitment demonstrated poor reliability (kappa = .54). Implications for practice and policy are explored.

105例儿童抽动障碍临床资料分析及中药疗效观察

目的 了解儿童抽动障碍的临床特点及中医证型分布，观察中药治疗儿童抽动障碍的临床疗效。方法 以确诊为抽动障碍的105例儿童作为研究对象，进行临床分析。在停用所有西药2周后，予自拟抽动1号方加减治疗3个月，观察疾病疗效和中医证候疗效。结果 105例儿童抽动障碍的临床表现多样化，误诊率高达57.1%，中医证型分布以肝亢风动型最多，自拟抽动1号方治疗儿童抽动障碍的总有效率达93.3%，随访1年后复发率为21.9%。结论 具有平肝熄风、镇静止痉功效的自拟抽动1号方对儿童抽动障碍有较好疗效，且无明显不良反应。
