膜攻击复合物对继发性脑损伤的影响

脑损伤后普遍存在的炎性反应激活补体并通过多种途径导致和加重继发性脑损伤。膜攻击复合物具有直接破坏血脑屏障、促使红细胞溶解、促进释放细胞因子、氧自由基和金属基质蛋白、加剧炎症反应的生物特性,从而加重继发性脑损伤。本文对膜攻击复合物造成继发性脑损伤的研究进行综述,希望能对相关研究和法医学鉴定提供参考。     

论兼采扶养丧失说与继承丧失说之可行性——对死亡赔偿中消极损害内容的再澄清

对于死亡赔偿中消极损害的内容,我国学界一般认为有扶养丧失说与继承丧失说两种不同的模式,并且这两种模式相互排斥,不能并存。这一看似合理、并有各国立法例支持的认识实际上存在很大问题。事实上,兼采扶养丧失说与继承丧失说并没有不可逾越的理论障碍。立法例上所谓的大多国家/地区均采扶养丧失说也只是学说上的一种概括,具体到各个国家/地区,均有所不同,没有必然的参考意义。相反,在我国,继承利益历来受到重视,因而将其与扶养利益分开,同时设立扶养利益与继承利益两个赔偿项目,具有重要意义。因此在我国,兼采扶养丧失说与继承丧失说更为合适。     

眼损伤法医学错误鉴定分析（附2例分析）

眼损伤法医学鉴定是法医临床学鉴定中的难点和研究热点,也是最容易出现错误鉴定的地方。本文针从两例错误鉴定入手,分析错误鉴定主要原因,一是鉴定人未关注病历材料中显示的重要信息,对病历材料中反映的既往病史、损伤动态发展及检查结果未予重视：二是鉴定人不具备眼损伤检查的基本技能,过度依赖外部信息。三是鉴定人不具备眼损伤的基础专业知识．对各类信息缺乏准确认识．对常见的眼损伤转归及预后不掌握。因此,结合上述问题,笔者建议鉴定人应当采取以下对策阻止或减少错误鉴定的发生,（1）完整审阅病历资料、影像学资料是基础;（4）实施细致、完善检查是关键;（3）准确把握鉴定标准是核心;（4）加强鉴定人专业技能和法律意识的提高是根本。     

高校学生伤害事故适用公平责任原则的分析--从我国相关立法视角所作的思考

公平责任原则能否适用于高等学校学生伤害事故,一直是高等学校学生伤害事故归责原则研究和适用中争议的焦点之一。争议在理论研究、司法实践和地方立法中的对立,实际是民法学界公平责任原则存废争议的延伸,源自对《民法通则》实施以来我国立法、司法解释,特别是《侵权法》相关规定的不同解读。对此所作的分层分析表明,我国法律既没有肯定公平责任原则的法律定位,也不存在公平责任原则适用于高等学校学生伤害事故的规定。“公平责任原则”只能作为归结法律责任以外社会责任的一项损害分担规则。     

Enhancing the Visibility of Injuries with Narrow‐Banded Beams of Light within the Visible Light Spectrum

The use of narrow‐banded visible light sources in improving the visibility of injuries has been hardly investigated, and studies examining the extent of this improvement are lacking. In this study, narrow‐banded beams of light within the visible light spectrum were used to explore their ability in improving the visibility of external injuries. The beams of light were induced by four crime‐lites^® providing narrow‐banded beams of light between 400 and 550 nm. The visibility of the injuries was assessed through specific long‐pass filters supplied with the set of crime‐lites^®. Forty‐three percent of the examined injuries improved in visibility by using the narrow‐banded visible light. In addition, injuries were visualized that were not visible or just barely visible to the naked eye. The improvements in visibility were particularly marked with the use of crime‐lites^® “violet” and “blue” covering the spectrum between 400–430 and 430–470 nm. The simple noninvasive method showed a great potential contribution in injury examination.     

建筑施工企业农民工工伤保险立法浅议

建筑行业农民工的工伤保险问题,已经引起社会各界的广泛关注。建立适合建筑行业农民工的工伤保险制度是保护农民工健康和维护社会稳定的必要条件。目前我国建筑行业农民工工伤维权存在一些问题,因此,需要建立符合我国建筑行业农民工自身特点的工伤保险。     

大鼠弥漫性轴索损伤后Homer1蛋白表达的研究

目的:观察大鼠弥漫性轴索损伤(DAI)后Homer1蛋白的表达规律。方法:将45只SD大鼠随机分为对照组及DAI组,后者按DAI后处死大鼠的时间不同分为30min、1h、3h、6h、12h、24h、72h、7d组。建立大鼠DAI动物模型,运用免疫组织化学技术及图像分析方法观察脑组织Homer1蛋白的表达。结果:损伤后30min,Homer1蛋白染色阳性细胞数增多,染色增强(P<0.05),随着损伤时间的延长,阳性细胞数及阳性表达范围逐渐扩大,于伤后24h达到高峰(P<0.01),随后逐渐下降。对照组可见少量Homer1蛋白表达。结论:Homer1蛋白是大鼠DAI后的灵敏指标,在不同时间段表达具有时序性变化规律,对于早期诊断DAI及损伤时间的推断具有一定的参考价值。     

Interpreting Injury Mechanisms of Blunt Force Trauma from Butterfly Fracture Formation

According to biomechanics of fracture production during blunt impact, tubular bones are subject to compressive (impact site) and tensile (opposite impact site) forces; this causes bones to break in tension before compression, producing Y-shaped fracture patterns with breakaway (butterfly) fragments. In current forensic models, the side of the bone exhibiting the breakaway fragment is designated the impact side, with initial breakage occurring opposite. Fracture production and patterning of blunt impacts to 255 sheep femora were analyzed. Contra the existing model, only 60% of complete butterfly fractures exhibited impact side breakaway fragments. Although fractures initiated on the tension, nonimpact side, butterfly fragments formed on either compression or tension sides. Using newly defined breakaway fragment shape criteria, impact side was estimated with 98% accuracy for both complete and partial butterfly fractures. Furthermore, the results suggest that the impact site is the located on one of the Y-fracture's arms, not the butterfly fragment's center, as previously modeled.
