我国药物滥用文献计量学研究

目的:了解我国近10a来药物滥用研究的文献状况。方法:采用"物质相关性障碍"为主题词,对《中国生物医学文献数据库》1997年-2006年收录的药物滥用文章进行检索和分析。根据《中国学术期刊综合引证报告》(2007版)提供的各项统计指标,对药物滥用领域的核心期刊进行分析。结果:(1)我国药物滥用研究论文的发表呈逐年上升趋势;(2)文献的著者以广东、北京和山东发文量最多,占50.4%;(3)大学的相关研究机构和附属医院发文量较多,占30%,其中北京大学发表最多;(4)药物滥用领域的研究中9.8%是基金资助的,而且基金资助数量也逐年增多;(5)载文量最多的期刊是《中国药物依赖性杂志》,其次是《中国药物滥用防治杂志》。结论:《中国药物依赖性杂志》和《中国药物滥用防治杂志》是药物依赖研究领域最受关注的期刊,具有较高的影响力和学术地位。     

山西省青少年毒品犯罪的成因及防控对策

毒品犯罪已经成为全球性的难题,近年来有愈演愈烈之势。尽管山西省并非我国毒品违法犯罪的高发省份,但毒品违法犯罪中青少年群体的参与程度和危害后果却不容忽视。实践部门要加大毒品危害性宣传,提高全民禁毒意识,同时强化青少年毒品违法犯罪的抑控机制,加强对青少年毒品违法犯罪的综合治理。     

贩毒案件中的诱惑侦查之合法性分析

当前,受国际毒潮的影响,我国的毒品犯罪形势日趋严峻,毒品消费以及毒品犯罪给社会造成的危害日益严重。鉴于贩毒案件的特殊性,在现实的迫切需要下,侦查部门在贩卖毒品案件侦查中开始适用诱惑侦查措施。国内关于诱惑侦查的合法性讨论较多,但少有结合具体案件实践分析适用诱惑侦查措施是否合法。在贩卖毒品案件中适用诱惑侦查措施有其必要性,从实体法、程序法角度看也具备合法性。     

On Correcting Biases in Self-Reports of Age at First Substance Use with Repeated Cross-Section Analysis

Household survey data on age at first use of alcohol, tobacco, marijuana,and hard drugs can be biased due to sample selection and inaccuraterecall. One potential concern is attrition, whereby individuals who getinvolved with substance use at an early age become increasingly less likelyto be surveyed in successive years. A comparison of data from the NationalHousehold Survey on Drug Abuse (NHSDA) with data from a longitudinal studysuggested that attrition might have caused substantially less bias thandid forward telescoping, the inflating of age at first useover time. The evidence of forward telescoping was particularly pronouncedwith respect to age at first use of alcohol. This paper presents a procedurefor correcting the distribution of age at first use for forward telescoping(but not attrition) by viewing a portion of the NHSDA data collected insuccessive years as constituting a cohort study. Results are presented fromapplying this procedure with NHSDA data collected from 1982 to 1995 forrespondents born 1968–1973. The findings suggest that preventionprograms need to be introduced at an earlier age than would be indicatedby uncorrected retrospective data. Other implications are alsohighlighted.     

Risk and Protective Factors Associated with Alcohol,Cigarette, and Marijuana Use During Adolescence

The purpose of this study was to increase the knowledge base of adolescent substance use by examining the influences of risk and protective factors for specific substance use, namely alcohol, cigarettes, and marijuana. Participants included 271 adolescents and their primary caregivers referred for mental health services across North Carolina. A series of hierarchical multiple regressions showed that the relative influences of risk and protective factors differed depending on the target substance in some cases. History of parental felony predicted use of all 3 substances, although the direction of association was substance specific. Parental behavioral control (how families express and maintain standards of behavior) was predictive only of cigarette and marijuana use, not alcohol use. The different links among risk factors, protective factors, and specific substance use are discussed, and recommendations for both mental health and substance use professionals are offered.She received her M.A. in Psychology from Wake Forest University and is currently a doctoral student in Clinical Psychology at the University of North Carolina at Greensboro.

Measurement Properties of the Communities That Care<Superscript>®</Superscript> Youth Survey Across Demographic Groups

Prevention science has produced information about risk and protective factors that predict adolescent drug use and related problem behaviors. This paper investigates the Communities That Care Youth Survey that measures multiple risk and protective factors. Using a sample of 172,628 students who participated in surveys administered in seven states in 1998, analyses were conducted to test the factor structure of these risk and protective factors and to test the equivalence of the factor models across five racial/ethnic groups (African Americans, Asians or Pacific Islanders, Caucasians, Hispanic Americans, and Native Americans), four grade levels (6th, 8th, 10th, and 12th) and both gender groups. Results support the construct validity of the surveys risk and protective factor scales and indicate that the measures are equally reliable across males and females and five racial/ethnic groups. Implications of these findings for science-based prevention planning are discussed.     

海洛因慢性依赖大鼠神经元一氧化氮合成酶变化

目的 研究海洛因药物滥用致脑神经细胞一氧化氮合成酶(ncNOS)表达的变化及法医学鉴定意义。方法 采用ncNOS免疫组织化学SP法、ncNOS mRNA原位分子杂交及图像分析技术,观察大鼠海洛因慢性依赖和自然戒断大脑皮质、中脑导水管周围灰质和中脑腹侧被盖区神经细胞ncNOS的变化和ncNOSmRNA的表达。结果 实验组神经细胞ncNOS含量和ncNOS mRNA表达比对照组明显增加,阳性细胞数明显增多;自然戒断组较慢性依赖组改变更加明显(P<0.05)。结论 ncNOS在海洛因慢性依赖和戒断中起重要作用,脑神经细胞ncNOS免疫组织化学变化可作为海洛因药物滥用法医学鉴定的形态学依据。     

毒品案件证据的法律适用--"毒品案件证据研究"课题组四川调研综述

毒品案件具有其自身的特殊性和侦查的特点,用事实推定原则来认定持有毒品人"明知".在证据尚不能证明行为人是为运输、贩卖时,才能按非法持有毒品罪论处;随时把证据固定下来用以证实犯罪,对技侦手段获取的证据,通过审批程序,步入法制化;对"特情"卧底取得的证据以变更方式处理.
