Discussing options between patients and health care professionals in genetic diagnosis: ethical and legal criteria

The specific characteristics of genetic data lead to ethical-legal conflicts in the framework of genetic diagnosis. Several international organisations, including UNESCO and the Council of Europe, have enacted rules referring to the use of genetic information. This paper discusses possible legal and ethical criteria that could be used in genetic testing.     

Controlled release of lidocaine hydrochloride from the surfactant-doped hybrid xerogels.

We investigate the controlled release of lidocaine hydrochloride from the doped silica-based xerogels. In the xerogel preparation, tetraethoxysilane (TEOS), methyltriethoxysilane (MTES), and propyltriethoxysilane (PTES) are used as precursors, and a nonionic surfactant Igepal CO 720 is used as a dopant. The experimental results suggest that the release of lidocaine hydrochloride can be easily controlled by partially substituting TEOS with the organosilanes, and/or by adding the dopant. Adding the organosilane precursors lowers the release of both the drug and the surfactant in the order of TEOS, MTES/TEOS, and PTES/TEOS xerogels. The release from the PTES/TEOS xerogels is much lower than that from the other xerogels. The release of lidocaine hydrochloride is obviously suppressed by the addition of Igepal CO 720, while the release of Igepal CO 720 is slightly promoted by the addition of the drug. The overall release process is found to be diffusion-controlled, and the release behaviors can be well explained by considering the effects of the textual properties of the xerogels and the interactions among the drug, the surfactant, and the xerogel matrices.     

对加强药品配送机构监督管理的思考

国家食品药品监督管理局在《关于全面开展加强农村药品监督网络建设促进农村药品供应网络建设工作的指导意见》中明确指出：“为配合药品配送、连锁进县到乡，各省（区、市）食品药品监督部门可以进行建立区域性药品配送站的研究和指导。在进行研究和探索过程中，鼓励将基层的药品批发企业改组成区域性药品配送站”。     

岗前标准预防教育对减少护生针刺伤的效果观察

岗前培训有助于提高护士技能[1]。医务人员由于职业原因引起可能致命感染(乙型肝炎、丙型肝炎、艾滋病),感染者多数为护士或临床实验工作者,暴露方式主要为暴露于病人的血液,多为针刺伤[2]。而实习护士自我防护意识不足,操作生疏,发生针刺伤比率大,约40.3%[3]。标准防护主张医护人员要严格执行消毒隔离制度和操作规程,充分利用各种屏障防护用具和设备,减少各种危险行为,最大限度地保护医护人员和病人安全。我院从2001年7月起对实习护生进行上岗前标准防护知识及操作培训,现报道如下。1材料与方法1.1研究对象2001年7月—2003年5月,来我院进行…

The genetic and epigenetic basis of ependymoma

Introduction  

Although ependymoma is the third most common pediatric brain tumor, we know little about the genetic/epigenetic basis of its initiation, maintenance, or progression. This is due in part to the heterogeneity of the disease, as well as the small sample size of the cohorts analyzed in most studies.
