A new mouse model for the neurodevelopmental ciliopathy Joubert syndrome

Recent recognition of the key role of primary cilia in orchestrating human development and of the dire consequences of their dysfunction on human health has placed this small organelle in the spotlight. While the causal link between mutations in ciliary genes and central nervous system malformations and dysfunction is well established, the mechanisms by which primary cilia dysfunction acts on development and function of the CNS remain partly unknown. The recent article by Bashford and Subramanian in The Journal of Pathology describes a new mouse model for the neurodevelopmental ciliopathy Joubert syndrome, supporting a role for ciliary-mediated Hedgehog signaling on proliferation, survival, and differentiation of cerebellar granule cell progenitors. © 2019 Pathological Society of Great Britain and Ireland.

师承教育在医教协同创新中医人才培养中的作用

中医师承教育是当今社会中医传承的主要方式,其培养了大量的中医优秀人才,促进中医药文化和中医学术思想传播,是现代中医药发展不可缺少的组成部分。但近代以来,人们脑海中逐渐形成了以西方医学为体系的思维模式时,中医学教育该如何的发展与传承。针对这一现象,我们分析了现代院校教育与师承教育的特点,阐述师承教育在现代中医人才培养中的作用,以期探讨高等中医药院校教育改革的模式。     

翻转课堂教学法在天然药物化学实验中的应用

目的利用翻转课堂教学法改进传统的天然药物化学实验课教学模式,提高该课程的教学效果。方法从实验教学的课程设计与开发,课前自主学习、课中内化及课后评估和讨论等环节进行了一系列的探讨与改革。结果翻转课堂教学模式为解决学生长期以来在天然药物化学实验课中缺乏主动参与性、探索性等问题提供一剂良方。结论在天然药物化学实验课教学中引入翻转课堂教学模式的初步探索为天然药物化学实验课的改革提供了依据和思路。     

单兆伟运用温经汤治疗女性肾虚泄泻经验

全国名中医、孟河医派传人单兆伟教授擅长胃肠病诊治,临证擅用《金匮要略》温经汤治疗女性肾虚型泄泻。认为温经汤的主要适应证是肝肾虚寒型的女性腹泻和(或)月经不调,肝脾肾三脏虚寒、寒凝而瘀、虚瘀相因、寒热错杂是温经汤证的病机特点,泄下清谷、脉象沉细或细涩、舌质淡黯有齿痕或瘀点是温经汤的主要应用指证。     

医用粘胶相关性皮肤损伤的文献计量学分析

目的: 应用文献计量学方法,分析国内外医用粘胶相关性皮肤损伤（Medical adhesive-related skin injuries,MARSI）文献的研究主题和热点。方法: 检索Cochrane Library、PubMed、EMbase、Web of science、sinoMed、CNKI、Wanfang、VIP等数据库MARSI相关文献,检索时限为建库至2019年5月。采用SPSS 22.0 软件进行文献计量分析,利用gCLUTO统计对国内外高频主题词进行聚类分析。结果: 共纳入论文103篇,其中外文文献占总文献量的27.18%,中文文献占总文献量的72.82%。聚类分析将国内外高频主题词聚为4大类,依次为皮肤损伤及损伤类型、相关危险因素、风险评估及风险管理、护理干预措施。结论: MARSI仍是国内外研究的热点,其发病机制研究仍处于探索阶段,目前尚缺乏有效的预防策略,研究领域较局限。在今后的研究中,应加强MARSI预防的研究、注重多学科合作。     

Sensory evoked potentials in patients with Rett syndrome through the lens of animal studies: Systematic review

ObjectiveSystematically review the abnormalities in event related potential (ERP) recorded in Rett Syndrome (RTT) patients and animals in search of translational biomarkers of deficits related to the particular neurophysiological processes of known genetic origin (MECP2 mutations).MethodsPubmed, ISI Web of Knowledge and BIORXIV were searched for the relevant articles according to PRISMA standards.ResultsERP components are generally delayed across all sensory modalities both in RTT patients and its animal model, while findings on ERPs amplitude strongly depend on stimulus properties and presentation rate. Studies on RTT animal models uncovered the abnormalities in the excitatory and inhibitory transmission as critical mechanisms underlying the ERPs changes, but showed that even similar ERP alterations in auditory and visual domains have a diverse neural basis. A range of novel approaches has been developed in animal studies bringing along the meaningful neurophysiological interpretation of ERP measures in RTT patients.ConclusionsWhile there is a clear evidence for sensory ERPs abnormalities in RTT, to further advance the field there is a need in a large-scale ERP studies with the functionally-relevant experimental paradigms.SignificanceThe review provides insights into domain-specific neural basis of the ERP abnormalities and promotes clinical application of the ERP measures as the non-invasive functional biomarkers of RTT pathophysiology.     

Content analysis of media coverage of breastfeeding in Mexico

Media can be a powerful communication tool to promote breastfeeding programs, influence mother's breastfeeding behaviour, and generate support among stakeholders for breastfeeding. Yet, there is little information on how media coverage influences a country's breastfeeding enabling environment. This study addressed this gap by conducting a retrospective content analysis of documents published between January 1, 2017 and January 1, 2018 to analyse the media coverage related to breastfeeding in Mexico. Content analysis was based on the breastfeeding gear model and a strategic planning technique to identify strengths, weaknesses, opportunities, and threats for enabling the national breastfeeding environment. Media coverage of breastfeeding was more frequent in August (36% of all documents). The top three topics commonly covered by the media were advocacy events promoting breastfeeding, promotion campaigns, and changes in breastfeeding legislation and policy. In general, the media coverage focused on strengths of specific breastfeeding policies. There was limited news coverage of key factors that negatively influenced or threatened the breastfeeding environment. Findings support the need to design strategies to engage the media covering in more depth and breadth diverse aspects of breastfeeding protection, promotion, and support efforts in Mexico.
