目的ZentangleR艺术治疗方法被应用于心理健康相关领域,尚未在边缘型人格障碍患者得到验证。本研究分析边缘型人格障碍患者接受ZentangleR艺术治疗方法的练习体验。方法采用现象学解释方法,对患者进行半结构化访谈。患者均已在西班牙某医院的人格障碍治疗室接受了每个月1次,共6次ZentangleR艺术治疗。本研究中共访谈了15例患者。Smith、Flowers和Larkin方法用于资料分析中的评估。结果根据研究结果,共提炼出3个类别的主题:有耕耘即有收获(参与者报告了注意力、放松、人际关系、与环境互动方面的改善,以及接受和改变的积极体验);众擎易举(患者认可在团体中感觉更好,并建立了相互联系;他们也描述了团体环境对个人行为的影响);画出自己的轨迹(通过绘画方式提供了自我表达和自我认识的媒介,通过情感表达提升了幸福感,提高了创造力,增强了自信心)。结论通过练习ZentangleR,患者可以作出灵活性和适应性等行为反应,通过焦虑管理、冲动控制改善情绪健康,学习应对问题,提高自尊或注意力。心理健康护理在边缘型人格的综合治疗及协同多样化补充性干预措施中发挥着积极作用。

Several receptors have been identified as implicated on viral entry into the hepatocyte; and, this interaction between the virus and potential receptors could modulate infection, spontaneous viral clearance, persistence of the infection and the widespread of the virus as outbreak. Nevertheless, the playing role of each of them remains controversial. The NiemannPick type C1 like 1 gene (NPC1L1) receptor has been recently implicated on hepatitis C virus (HCV) entry into the cell and ezetimibe, an anti-cholesterol drug seems to block that, emerging the idea to control hepatitis C outbreak modulating lipid-related receptors. Hepatitis C infection seems to modulate lipid metabolism according to host genetic background. Indeed, it circulates like a lipoviroparticle. The main aim of this field of vision would be to discuss the role of hepatocyte receptors implicated on virus entry, especially NPC1L1 and the therapeutic options derived from the better knowledge about HCV-lipidsreceptors interaction.
