论中国艾滋病立法的基本框架

艾滋病立法的框架包括初步的立法体系及其主要内容。17年来,中国艾滋病立法从无到有,从分散到系统,形成了具有中国特色的初步的艾滋病立法体系。内容大致包括:艾滋病的地位与性质、主管部门与防治机构,艾滋病的防治对象与范围,防治方针与原则,权利与义务,宣传教育与行为干预,疫情监测与疫情报告等。     

A Case Control Study of Adolescent Risky Sexual Behavior and Its Relationship to Personality Dimensions,Conduct Disorder,and Substance Use

In comparison to the general adolescent population, adolescents with a history of externalizing behaviors including substance use and conduct disorder are younger at first intercourse, have a larger number of sexual partners, and use condoms less often when they engage in intercourse, placing them at higher risk for sexually transmitted diseases as well as unplanned pregnancy (Morris, R. E., Baker, C. J., Valentine, M., and Pennisi, A. J. (1998). J. Adolesc. Health 23: 39–48). A primary goal of this paper was to examine linkages between Cloninger's novelty-seeking, harm avoidance, and reward dependence dimensions and risky sexual behavior among 200 boys in treatment for substance abuse and delinquency compared to 200 boys recruited from the community, and matched on age, ethnicity, and geographic location. Analyses indicated that though there were mean differences on all personality constructs examined, these differences in personality failed to account for observed differences in risky sexual behavior. The structure of problem behavior also differed in the 2 groups.     

Comparison of HIV Risks among Gay,Lesbian, Bisexual and Heterosexual Homeless Youth

Youth who are homeless and gay, lesbian or bisexual (GLB) are one of the most disenfranchised and marginalized groups in our society. The purpose of this study is to examine and compare HIV in GLB homeless youth with their heterosexual counterparts. Participants for this study included 268 youth involved in treatment outcome studies with substance abusing homeless youth. Results suggest that GLB youth have greater HIV risks and that these risks are greater among bisexual females. In examining the predictors of sexual health risks, survival sex emerged as the most significant. Survival sex was high among females regardless of their sexual orientation and also among gay males. Implications of these findings suggest that a greater emphasis needs to be paid to preventive interventions among this population.

NIST Mass Spectrometry Data Center standard reference libraries and software tools: Application to seized drug analysis

The standard reference libraries and associated custom software provided by the National Institute of Standards and Technology's Mass Spectrometry Data Center (NIST MSDC) are described with a focus on assisting the seized drug analyst with the identification of fentanyl-related substances (FRS). These tools are particularly useful when encountering novel substances when no certified sample is available. The MSDC provides three standard reference mass spectral libraries, as well as six software packages for mass spectral analysis, reference library searching, data interpretation, and measurement uncertainty estimation. Each of these libraries and software packages are described with references to the original publications provided. Examples of fentanyl identification by gas chromatography–mass spectrometry (GC–MS) and by direct analysis in real-time (DART) mass spectrometry are given.

社会性别与艾滋病——对一位女性艾滋病患者生命历程的性别分析

本研究运用质性研究方法,对一位女性艾滋病患者的生命历程进行了社会性别分析。研究认为,传统的社会性别制度恶化了女性艾滋病患者的社会处境,尤其是从夫居和父系继嗣制度不仅使女性在患病后难以获得家庭和社区的支持,而且容易面临来自家庭和社区的双重压力。在艾滋病的防治中,应更关注女性的权益保护。     

2′-氯地西泮在大鼠体内分布及代谢降解规律研究

目的研究2′-氯地西泮及其代谢物(地洛西泮、氯甲西泮、劳拉西泮)在大鼠体内分布及代谢规律,为2′-氯地西泮相关案件的检验提供实验数据。方法40只SD大鼠随机分为4组,禁食12h,按2.625mg/kg 2′-氯地西泮灌胃给药,第一组给药后不同时间点经大鼠尾静脉采血,第二组为采血空白对照组,第三组给药30min后处死,取心、肝、肺、肾、脑、睾丸,经乙酸乙酯液液萃取后用高效液相色谱-三重四极杆质谱检测2′-氯地西泮及代谢物含量,第四组为分布空白对照组。结果2′-氯地西泮进入体内后,迅速代谢分布,在20min内达到血液最高浓度。2′-氯地西泮及代谢物在各器官中的分布特点为:肝>脑>心脏>肾>睾丸>肺。结论经灌胃2′-氯地西泮进入大鼠体内后,监测2′-氯地西泮及其代谢物在大鼠体内的分布及降解规律可以为2′-氯地西泮相关案件的检验鉴定提供参考依据。     

Determination of blood-harbored 2′-diclazepam with auto-spe and gc-ms/ms

Objective To develop a GC-MS/MS method for determination of 2′-diclazepam in blood. Methods The sampling blood was extracted via HLB cartridge (a product from Waters Corporation, enabling operation of the auto-SPE (solid-phase extraction) for this determination) that was eluted with ethyl acetate, having the collected eluate subjected to GC MS/MS analysis. Results For the 2′-diclazepam tested, a linear relationship was present between the concentration and peak area from the calibration curve in the range of 20 ～ 20μg/mL, demonstrating the limit of detection (LOD) being 10ng/mL. Moreover, the average recoveries were shown within the range of 81.8%~90.4%, and the relative standard deviations among 4.89%~5.47%. Conclusion The here-established method is of high sensitivity, selectivity and strong operability, suitable for determination of diclazepam in blood. © 2021, Editorial Office of Forensic Science and Technology.

子弹弹头及弹壳成分比较研究

目的对子弹物证进行成分分析可为涉枪案件的侦查提供科学依据。本实验旨在通过研究子弹弹头及弹壳的元素组成快速区分不同子弹,为推断子弹来源提供关键信息。方法收集不同厂家在1958-2019年不同批次生产的多种型号的子弹样品53份,应用扫描电镜能谱法(SEM/EDX)对样品的弹头内芯、弹头披甲和弹壳金属成分进行研究。结果结果显示多数子弹弹头内芯由纯铅构成,部分批次较晚的弹头为铅锑合金,另有两枚批次较早子弹为铁弹头;除六枚5.6mm运动步枪弹的弹头披甲以及四枚791厂样品的弹壳无明显特征外,其余子弹的弹头披甲和弹壳均为三类铜锌合金中的一种:含铜量83.7%~84.7%、87.6%~90.6%以及67.0%~69.8%的铜锌合金。同型号同厂家子弹所使用弹头披甲及弹壳材料的特征相似,同型号不同厂家、同厂家不同型号的子弹弹头披甲和弹壳材料则具有一定差异。近六十年来121厂样品子弹弹头披甲均为含铜量87.6%~90.6%的铜锌合金,弹壳材料为含铜量67.0%~69.8%的铜锌合金,其为该厂固定使用的铜锌合金原材料的可能性较高。791厂样品中有四种型号的子弹弹壳均为含锰量0.7%~0.9%的铁锰合金,这种合金在其他厂家并未出现,其为791厂弹壳特征原材料的可能性较高。结论掌握子弹弹头及弹壳的元素组成特征可以对不同子弹进行有效识别。     

Fathers’ Perspectives Regarding Their Children’s Exposure to Intimate Partner Violence

Children exposed to intimate partner violence are at high risk for mental health and behavioral problems. Numerous studies have examined mothers’ perceptions about the influence of exposure to violence on their children; few studies have examined the views of violent fathers. This study sought to identify how fathers, participating in batterer intervention programs (BIP), perceive consequences of their violence on their children and how they protect and mitigate the destructive effects of their violence on their children. Semi-structured interviews were conducted with 21 fathers, with a qualitative approach for analysis. The findings highlight the need for specific intervention for fathers.     

柬埔寨艾滋病治理成效及其原因评析

作为典型的弱小国家,柬埔寨在艾滋病治理上为世界树立了一个重要的榜样。经过20多年的努力,柬埔寨的艾滋病治理取得了显著的成效,主要表现在:艾滋病感染率大大降低,每年新增艾滋病感染人数大幅减少,艾滋病患者接受治疗的比例不断提升。取得这种成效的原因首先是柬埔寨政府对于艾滋病的安全化定位与实践,树立了政府治理的决心与魄力;其次是非政府组织对艾滋病治理的积极参与,奠定了艾滋病治理的社会基础;最后是国际社会的援助为柬埔寨艾滋病治理提供了强大的动力。这三个因素构成了柬埔寨艾滋病治理取得显著成效的三驾马车。
