猪生殖与呼吸综合征病毒和猪圆环病毒2型共感染对猪外周血天然免疫细胞含量的影响

将猪生殖与呼吸综合征病毒(PRRSV)和猪圆环病毒2型(PCV2)单感染和共感染的6周龄仔猪,于感染前和感染后第3、7和10 d,采用血常规法、SWC3a单色流式细胞术以及CD3/CD4/CD8三色流式细胞术分析了感染猪外周血中白细胞、粒细胞、单核细胞、NK细胞、γδT细胞的含量。结果,感染后第3 d和第7 d,PRRSV感染组、PCV2感染组以及PRRSV+PCV2共感染组猪的白细胞、单核细胞、粒细胞、NK细胞、γδT细胞总数显著下降,并且共感染组比单感染组下降更加严重。结果表明,PRRSV+PCV2共感染对仔猪外周血天然免疫细胞的影响具有协同效应,意味着在感染早期可导致更加严重的先天免疫抑制。     

气相色谱仪双毛细管柱双检测器技术在毒物检测中的应用

目的利用双毛细管柱双检测器技术建立常见毒物的检验方法,并对其进行定性分析。方法样品进样后通过VSOS装置进入两根不同极性的毛细管柱,经分离后到达两个不同选择性的检测器。结果利用VSOS装置可对毒物进行较好的分离、定性。结论该方法可对常见毒物进行准确定性。     

8例利多卡因过敏性休克死的血药浓度分析

目的研究利多卡因过敏性休克死者利多卡因血药浓度及其与死因的关系。方法采用高效液相色谱法(HPLC),分别对使用利多卡因麻醉术中各项指标均正常的8例术中因利多卡因过敏性休克死者的血液和11例顺利完成手术患者的血液进行利多卡因浓度的检测,对比分析两者结果。结果 8例死者利多卡因血药浓度(1．61mg± 0．45mg／L)低于11例正常患者利多卡因血药浓度(2．44mg±0．47mg／L)。结论利多卡因过敏性休克死者血药浓度在正常值范围内,与发生过敏性休克致死无关。     

SPECIAL NEEDS CHILDREN IN FAMILY COURT CASES

This article presents a conceptual framework for describing cases involving children with special needs that are increasingly being seen in family court. Three categories that represent the most common of such cases include (1) acute, life-threatening medical conditions; (2) chronic developmental disorders; and (3) psychological and behavioral syndromes. After detailing the nature of the disabilities in each category, perspectives from the bench are offered with specific recommendations and general strategies for effective case management. This is followed by a proposal of an innovative conceptual model—the Individualized Parenting Plan (IPP)—that organizes and integrates nine domains essential for a comprehensive parenting plan for special needs children. The article concludes with a list of sixteen strategic guidelines for servicing the families of these special needs children, in their best interests.

论警检关系的基本特征与发展趋势

尽管世界上几个主要国家的警检关系存在三大模式的分野,但各国警察机关和检察机关之间既存在形式上的分工关系,又具有实质上的合作关系,只不过三大模式的侧重点有所不同而已。大致说来,英美模式的侧重点在审判程序,而大陆模式、中俄模式的侧重点在审前程序。但从一些国家近年来的司法改革看,三大模式在相互吸收的基础上,警检关系开始出现紧密化的发展趋势。     

贪污受贿犯罪定罪量刑标准的变迁与反思——以《刑法修正案(九)》的出台为视角

1997年《刑法》以数额为中心的定罪量刑标准缺乏社会适应性;各法定刑量刑幅度交叉现象严重;贪贿犯罪刑罚减免规定存在"宽严皆失"的弊端;生刑与死刑差距过大,资格剥夺措施一直缺位。《刑法修正案(九)》虽针对诸多问题作出了调整,但贪污与受贿的关系、终身监禁的落地实施等问题仍有待研究。为此,应降低贪贿入罪标准,扩大地方自由权,以无期徒刑重构终身监禁制度,厘清贪污受贿关系并严密刑罚裁量情节,废除贪贿犯罪刑罚减免制度。     

高铁隧道内气动效应形成损坏痕迹特点分析

动车高速通过隧道时,运行车体推动的空气由于受到隧道壁的约束能形成能量很强的冲击气流,有时会造成一些设备设施损坏、脱落,进而危及高铁行车安全。这类事件发生后,铁路部门往往误以为是人为破坏,并以破坏案件进行上报。本文通过对特定动车行车事故的现场勘验、调查访问,分析了高铁隧道内气动效应对特殊位置设施造成损坏的过程及形成痕迹特点,准确认定了事件性质和事故发生原因,并对气动效应形成损坏痕迹和常见工具形成痕迹的区别进行了探讨。     

Do volatile voters vote less correctly? An analysis of correct voting among vote (intention) switchers in US presidential election campaigns

The literature on electoral volatility and the literature on electoral campaigns hold contradictory views on voters switching vote (intention) during the campaign. In this note, we shed new light on this contradiction, making two contributions. First, we investigate the extent to which stable and volatile voters choose the correct party. Second, we distinguish levels of correct voting and the impact of the act of switching on the correctness of the vote. Our analyses of vote-switching in American elections show that, while volatile voters are less likely to vote correctly, they are more likely to switch from an incorrect to the correct party than vice versa. Furthermore, we show that following the campaign more closely makes voters more likely to switch vote (intention) towards the correct party.
