损伤皮肤中白三烯B_4含量测定与损伤时间推断

本文作者利用高压液相色谱,快速检测大鼠皮肤切创创缘组织中白三烯B_4含量。结果发现,生前各损伤时间组创缘中白三烯B_4含量明显升高,且在1小时内与损伤时间有一定线性关系;死后损伤标本未见白三烯B_4含量升高。由此表明白三烯B_4含量测定,对推断生前1小时内的损伤时间有重要价值。高压液相色谱能快速、准确地检测损伤组织中的白三烯B_4。     

论行政自由裁量权的法律控制

行政自由裁量权是现代行政权力的重要组成部分。如果没有自由裁量权的存在,现代行政就失去了其价值和意义。然而自由裁量权因其“自由”的属性又使它极易被滥用,从而出现错位。为了保证行政自由裁量权的合理运作,建议从完善立法、健全司法监督制度、提高公务员的素质和公民的法律意识等几个方面加强对自由裁量权的法律控制。     

滥伐林木行为之行政法律责任评析

对滥伐林木行为追究行政责任时存在行政处罚的执法阻力较大,征收罚款的理论依据不足,行政罚款责任得来的资金的管理和使用不当等缺陷.本文认为,应当恢复民事责任、行政责任合理分界的状态,行政责任必须退出且应当完全可以由民事责任发生作用的领域;应当对滥伐林木行为人追究惩罚性民事损害赔偿责任.     

利用铣纹痕迹数量和角度判断钢丝钳剪切位置

目的观察钳剪钢丝铣纹痕迹规律。方法用钢丝钳剪切铁丝,观察形成铣纹痕迹的特点和规律,并对铣纹痕迹数量和倾斜角度与钢丝钳剪切刃口位置的关系予以分析。结果钢丝钳刃口形成的铣纹痕迹数量和倾斜角度随刃口位置变动而发生相应变化。结论通过检测铣纹痕迹的数量和倾斜角度能可靠判断剪切刃口的具体位置,为制作样本选择刃口部位提供依据。     

屠城、妄杀与死刑奏报——论蒙元时期死刑文化的转化

蒙古帝国初进中原的屠城之制,是根据蒙古传统法令而进行的一种刑事惩罚,它并不包括在成吉思汗所禁止的“妄杀”的范围内。但在向中原汉文化地区不断扩张的过程中,面对着草原游牧文化与中原农耕文化的冲突,蒙古统治者也不得不逐步改变其政策和法令,其草原法文化也开始深受中原地区法文化的影响,表现在死刑方面的转化就是把屠城包括在妄杀之中加以禁止,并在忽必烈时代开始建立起死刑的奏报制度,对死刑加以控制。但和唐代等比较起来,元代的死刑程序比较粗略。     

Bolt Cutter Blade's Imprint in Toolmarks Examination

Bolt cutters are known as cutting tools which are used for cutting hard objects and materials, such as padlocks and bars. Bolt cutter blades leave their imprint on the cut objects. When receiving a cut object from a crime scene, forensic toolmarks examiners can determine whether the suspected cutting tool was used in a specific crime or not based on class characteristic marks and individual marks that the bolt cutter blades leave on the cut object. The paper presents preliminary results of a study on ten bolt cutters and suggests a quick preliminary examination—the comparison between the blade thickness and the width of the imprint left by the tool on the cut object. Based on the comparison result, if there is not a match, the examiner can eliminate the feasibility of the use of the suspected cutting tool in a specific crime. This examination simplifies and accelerates the comparison procedure.     

基于板蓝根中（R,S）-告伊春含量研究板蓝根加工方法

目的 研究不同干燥方法及软化切制方法对板蓝根中（R,S）-告伊春含量的影响,从而建立提升黑龙江产板蓝根质量的加工方法。方法 采用高效液相色谱法对板蓝根中（R,S）-告伊春含量进行测定,比较晒干与烘干板蓝根药材的（R,S）-告伊春含量差异,比较不同投料形式板蓝根颗粒和饮片中（R,S）-告伊春含量差异。结果 60 ℃烘干后的板蓝根药材中（R,S）-告伊春含量高于晒干的板蓝根药材,且能明显缩短板蓝根药材的产地干燥时间;经软化切制的板蓝根饮片中（R,S）-告伊春含量明显高于板蓝根粗颗粒。结论 在板蓝根产地加工过程中,可用烘干法代替晒干法;以板蓝根药材作为中成药投料,建议采用软化切制后的板蓝根饮片。     

弹膛后切口刮擦痕迹在认定发射枪支中的作用

弹膛后切口刮擦痕迹属于弹膛的使用、擦拭痕迹中的一种,是退壳过程中射击弹壳壳体与弹膛后切口棱边发生轴向切划而形成,具有成痕面积大、成痕深、反映稳定等特点,在认定发射枪支中价值极高。     

Self‐harm Risk Among Adolescents and the Phenomenon of the “Blue Whale Challenge”: Case Series and Review of the Literature

The “Blue Whale Challenge” is a dangerous Internet phenomenon. As per media reports, it involves a series of life‐threatening tasks imposed by a “curator” to “players,” who must fulfill the whole list, and it ends with the suicide of the player. The authors report the data of five suspected cases of “Blue Whales” managed from January 2016 to December 2017 by the staff of a unit (the “Bambi Unit” of the Pediatric Hospital “Regina Margherita” of Turin, Italy) that is dedicated to the evaluation of suspected abused children. Then, they analyzed this data in the light of the literature regarding self‐harm. This comparison highlights the role of the Internet in the spreading of self‐harm behavior among vulnerable adolescents who are characterized by epidemiological, psychological, psychiatric, social, and cultural risk factors. In conclusion, the authors suggest a multidisciplinary and specialized approach in the evaluation of adolescents who committed self‐harm activities.     

浅谈盗割回流线案件的现场勘查

盗割回流线案件是近年来铁路沿线多发的一种危及行车安全的刑事案件,因其现场多且处于野外而给现场勘查带来很大难度。这类案件的现场勘查,首先应利用回流线上遗留的痕迹特征,分析作案工具的种类,同时要特别注意外围现场遗留的痕迹、物品。
