亚洲槟榔文化圈探析

槟榔文化的形成和发展与槟榔自身特殊的属性、当地的地理环境以及审美观念等均有密切关系。自古以来,中国、东南亚与南亚一带的居民就养成了嚼食槟榔的生活习惯,并形成了与槟榔有关的习俗和文化。由于近代以来自然环境改变、医药卫生科学知识普及、审美观念、婚俗变化以及新嗜好品的出现,槟榔在一些地区已经退出市场,但许多国家和地区至今仍然保留嚼食槟榔的习俗。     

GC/MS法测定人体血液和肾、肝组织中的丙泊酚

目的 采用气相色谱/质谱法检测人体血液和肾、肝组织中的丙泊酚.方法 心血和肾、肝组织中的丙泊酚经环己烷提取,采用气相色谱/质谱法,丙泊酚选择m/z 163、178,内标百里香酚选择m/z 150、135进行测定;并考察方法专属性、线性范围、定量线与检出限、回收率与精密度.结果 丙泊酚的保留时间为8.17min,与内标百里香酚分离良好;其在心血和肾、肝组织中的检测浓度线性关系良好,r值均大于0.992,最低检测质量浓度分别为0.05 μg/mL、0.10μg/g及0.05 μg/g,方法回收率90％ ～ 110％,日内、日间RSD均小于7％.结论 本文方法简便、灵敏、快速,其准确度、精密度和回收率均可满足生物检材中丙泊酚浓度的测定,可在相关研究及实践中选用.     

大鼠脑外伤后脑组织MMP-9的表达与损伤时间相关性

目的观察大鼠脑外伤后脑组织MMP-9的表达规律,探讨其在损伤时间推断中的应用价值。方法健康SD大鼠75只,随机分为损伤组、假损伤组和正常对照组。损伤组采用自由落体方法建立脑损伤模型;致脑损伤后分10个时间点,采用HE染色观察损伤区的变化,采用免疫组化方法检测各时间点阳性细胞的种类和比值,并与假损伤组和对照组进行统计分析比较。结果免疫组化染色显示损伤组伤后1h可见中性粒细胞阳性着色,6h后可见神经细胞阳性染色并逐渐增强,伤后5d阳性细胞数达到峰值,而后开始减弱,14d基本消失。假损伤组和正常对照组未见阳性表达。将实验组中2h～7d阳性细胞比值与其它各时间点相比,差异有统计学意义(P<0.05);实验组各时间点与假损伤组和对照组相比,差异均有统计学意义(P<0.05)。统计分析结果见表1。结论损伤后MMP-9阳性表达的规律性,有望成为脑损伤时间判定的参考指标。     

FTA战略:韩国经济发展的加速器

FTA是自由贸易协定(Free Trade Agreement)的简称,指两个或两个以上的国家(包括独立关税地区)根据WTO相关规则,为实现相互之间的贸易自由化所进行的地区性贸易安排.由自由贸易协定的缔约方所形成的区域称为自由贸易区,区内各成员国之间取消商品货物贸易的关税和数量限制,使区域内各成员的商品实现完全自由流动.     

Determination of Adenosine Phosphates in Rat Gastrocnemius at Various Postmortem Intervals Using High Performance Liquid Chromatography

Abstract: Although the change in adenosine phosphate levels in muscles may contribute to the development of rigor mortis, the relationship between their levels and the onset and development of rigor mortis has not been well elucidated. In the current study, levels of the adenosine phosphates including adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine monophosphate (AMP) in gastrocnemius at various postmortem intervals of 180 rats from different death modes were detected by high performance liquid chromatography. The results showed that the levels of ATP and ADP significantly decreased along with the postmortem period of rats from different death mode whereas the AMP level remained the same. In addition, it was found that changes in the ATP levels in muscles after death correlated well with the development of rigor mortis. Therefore, the ATP level could serve as a reference parameter for the deduction of rigor mortis in forensic science.     

对运用电脑绘制犯罪现场图技术存在问题的思考

目前,全国各级公安机关根据公安部的统一要求,除了绘制犯罪现场草图外,均要求用电脑绘制犯罪现场正式图,这也是公安执法规范化的具体要求之一。经过十多年的不断努力,运用电脑绘制犯罪现场图技术得到了长足的发展,然而,当前各级公安机关在利用电脑绘制现场图时却仍然存在具体操作上的难点,希望得到进一步的完善和解决。     

中国农民利益表达机制之完善研究

我国当前农民利益表达机制的不完善和诉求管道的堵塞严重损害了农民群体的利益,导致农民对政府的不信任感甚至敌对感持续增强,这为政府政策的落实带来诸多障碍,有效的利益表达机制的构筑已成为燃眉之急。针对当前我国农民利益表达机制中存在的问题,笔者认为,应当从利益表达的主体、客体、渠道、载体、工具五个方面入手,进一步完善现有的利益表达机制。     

Shoot/No-Shoot Decisions: Dissociation,Judgment, and Assailant/Weapon Characteristics

Shoot/no-shoot decisions in law enforcement are under increasing scrutiny nationwide. However, little research has addressed the ways in which factors related to assailants and weapons influence these decisions. In the present research, images of adult male, adult female, and juvenile (female) assailants presented simulated direct threats to respondents. Assailants were armed with a pistol, a knife, or a glass bottle. Respondents were asked to indicate whether or not they would shoot in the presence of these threats. Respondents also completed the Dissociative Experiences Scale (DES). Tendencies toward dissociation, a process generating a sense of unreality, influenced the performance of males who shot; more dissociated men took more time to fire. However, dissociation did not influence the performance of women. Sex and youth of the assailant had no effects on the shoot/no-shoot performance of either men or women, and oddly, weapon type had no significant effect on women’s performance, although men were more likely to fire on an assailant of either age or sex armed with a gun or knife than a bottle. These results are discussed in terms of relevance for law enforcement training and for juridical proceedings in shoot/no-shoot cases.     

关于高校物资实行政府采购的思考

按照政府采购法的要求,高校物资应实行政府采购。但这一采购模式目前仍处于尝试阶段,高校采购部门对其认识也不太明确,如何正确认识、实施政府采购以及实施政府采购过程中需注意哪些问题值得我们思考。     

人民监督员制度的反思与建构

为了顺应公民参与司法的国际化潮流,加强检察机关查办职务犯罪案件的外部监督机制,创立了人民监督员制度。人民监督员制度无疑具有科学性与合理性,但是在发展过程中也确实存在着一些问题,须对人民监督员制度进行立法整合。
