沙苑子本草考证

沙苑子为我国常用中药,药用历史悠久。通过查阅本草文献,对沙苑子名称、基原、功效、产地及伪品5个方面进行考证,得知其名称演变大致经过"白蒺藜""沙苑蒺藜""沙苑子"3个阶段;历代本草记载沙苑子基原为扁茎黄芪的干燥成熟种子,古今应用品种基本一致;沙苑子补肾固精功效的记载自宋《本草衍义》起逐渐清晰明确;沙苑子道地产区自宋时起为陕西沙苑,明清时期产地逐渐转到陕西潼关、山西等地,建国后以陕西省为主向北扩散,以陕西潼关为佳;沙苑子建国前有马薸子、色微绿伪品及紫云英子等混伪品,建国后有紫云英、猪屎豆、华黄芪和直立黄芪的种子等混伪品。为沙苑子正本清源,并为其进一步深入开发提供参考。     

玫瑰花口服液的红外指纹图谱及化学模式识别

目的:采用红外光谱和化学模式识别相结合建立了玫瑰花口服液质量评价的方法。方法:以11批玫瑰花口服液和4种伪品作红外光谱分析,对主要吸收峰进行指认,获得红外指纹图谱,并按不同特征吸收峰位下的透射比进行相似度计算,通过相似度分析对11批玫瑰花口服液及4种伪品的红外图谱一致性进行了考察,并把获得的指纹图谱采用系统聚类分析和主成分分析进行化学模式识别。结果:11批玫瑰花口服液红外指纹图谱一致性良好,玫瑰花口服液及伪品通过相似度分析和化学模式识别均能够很好地区分开来,相似度和聚类分析、主成分分析结果相一致,2种化学计量方法具有良好的相关性。结论:结果表明该方法是鉴别玫瑰花口服液真伪的有效方法。

中药制剂通心络胶囊近红外定性模型的建立

目的建立石家庄以岭药业股份有限公司的通心络胶囊的近红外定性模型。方法在OPUS的Setup Conformity Test模块中,取7502.3~4999.0cm-1谱段范围的漫反射光谱,进行一阶导数对数据前处理后,建立定性模型。结果 36批通心络胶囊均在模型设定CI限度范围内,而2批假冒品均在模型设定CI限度范围外。结论建立该药的定性模型可在打击假冒品中应用。     

The Internet and lifestyle drugs: an analysis of demographic characteristics,methods, and motives of online purchasers of illicit lifestyle drugs in the Netherlands

Abstract

Aims: The Internet has marked a revolution in the supply of illegal drugs, while at the same time, new types of illegal and semilegal drugs increasingly are becoming available. In order to deepen our understanding of the demand and supply of these new drugs on the Internet, this study focuses on the demographic characteristics, methods and preferences of people who purchase ‘lifestyle drugs’ through the surface web.

Methods: Data were obtained through the following two surveys: a prevalence study of 50,848 Dutch respondents and an in-depth study of 153 people who have purchased lifestyle drugs online.

Findings: At least 10.2% of the Dutch adult population has bought medicines online; the majority being lifestyle drugs (5.2%). In addition, an estimated 1.6% of the Dutch population has purchased medicines illicitly, with the majority of products concerning lifestyle drugs (0.9%). Illicit lifestyle drugs are primarily purchased through e-commerce sites and online pharmacies, and users report high satisfaction rates.

Conclusion: Purchasing lifestyle drugs is characterised by specific online dynamics, as the drugs are often openly accessible and the boundaries between legal and illegal sale blurred. As new types of drugs become available, it is important to further monitor customers’ preferences and experiences.
