Subduction plays a fundamental role in plate tectonics and is a significant factor in modifying the structure and topography of the Earth. It is driven by convection forces that change over a >100 Myr time scale. However, when an oceanic plateau approaches, it plugs the subduction, and causes slab necking and tearing. This abrupt change may trigger a series of geodynamic (tectonic, volcanic) and sedimentary responses recorded across the convergence boundary and its surrounding regions by synchronous structural modifications. We suggest that a large enough triggering event may lead to a ripple tectonic effect that propagates outwards while speeding up the yielding of localized stress states that otherwise would not reach their threshold. The ripple effect facilitates tectonic, volcanic, and structural events worldwide that are seemingly unrelated. When the world’s largest oceanic plateau, Ontong Java Plateau (OJP), choked the Pacific-Australian convergence zone at ~6 Myr ago, it induced kinematic modifications throughout the Pacific region and along its plate margins. Other, seemingly unrelated, short-lived modifications were recorded worldwide during that time window. These modifications changed the rotation of the entire Pacific plate, which occupies ~20% of the Earth’s surface. In addition, the Scotia Sea spreading stopped, global volcanism increased, the Strait of Gibraltar closed, and the Mediterranean Sea dried up and induced the Messinian salinity crisis. In this paper, we attribute these and many other synchronous events to a new “ripple tectonics” mechanism. We suggest that the OJPincipient collision triggered the Miocene-Pliocene transition. Similarly, we suggest that innovative GPS-based studies conducted today may seek the connectivity between tectonic, seismic, and volcanic events worldwide.

Current viewpoints on platelet contribution to inflammation

World Journal of Hematology 2012年第4期1卷 14-21页

Inflammation is an underlying feature of a variety of human diseases. Because inflammatory diseases are a major cause of morbidity and mortality in developed countries, understanding the interaction of the most important factors involved is an important *** platelets are widely recognized as having a critical role in primary hemostasis and thrombosis, basic and clinical evidence increasingly identifies these enucleated cells as relevant modulators, as both effector and target cells, of the inflammatory response. The cross-talk between platelets, endothelial cells and leukocytes in the inflammatory milieu mat be seen as a double-edged sword which functions not only as an effective first-line defense mechanism but may also lead to organ failure and death in the absence of counter-regulation *** molecular mechanisms involved in the reciprocal activation of platelets, endothelial cells and leukocytes are beginning to be elucidated. In the light of the existing data from experimental and clinical studies it is conceivable that platelet adhesion molecules and platelet mediators provide promising targets for novel therapeutic strategies in inflammatory diseases. The potentially adverse effects of these approaches need to be carefullyaddressed and monitored, including alterations in hemostasis and coagulation and particularly the impairment of host defense mechanisms, given the recently identified pivotal role of platelets in pathogen recognition and bacterial trapping. In this review we discuss the most important recent advances in research into the cross-talk between platelets and vascular cells during inflammation and the clinical consequences of these interactions.

人类病毒感染常引起各种自身抗体的短暂出现,在某些患者可导致自身免疫性组织损伤和疾病的发生。这种引起或加重自身免疲过程的能力为许多病毒所共有,动物模型证明它主要影响病毒在其中复制的器官。自身免疫病患者存在病毒的'足迹',包括特异性抗病毒抗体效价高,病毒序列的存在以及血清内出现α干扰素。病毒诱导自身免疫的发病机理可为:病毒对宿主免疫系统的直接或间接影响;抗病毒抗体对机体的有害作用;病毒诱导宿主的抗原变化。

作者： Ami schattner 武昱 Department of Medicine Kaplan Medical Centre Hebrew University and Hadassah Medical School Jerusalem Israel 中华检验医学杂志编辑部

众所周知，内科住院医师的第一年常常会产生倦怠感。这有可能导致对患者的治疗欠佳、工作失误、生活质量降低以及抑郁。关于住院医师开始的数周与住院医师第一年内的其他时间相比发生倦怠的研究数据尚未公布。

Difficulties in Recruitment for a Randomised Controlled Trial of Lifestyle Intervention for Type 2 Diabetes: Implications for Diabetes Management

引用

Open Journal of Endocrine and Metabolic Diseases 2012年第4期2卷 53-57页

作者： George A. Jelinek Emily Hadgkiss Craig Hassed Bernard Crimmins Peter schattner Danny Liew Rick Kausman Warrick J. Inder Siegfried Gutbrod Tracey J. Weiland Department of General Practice Faculty of Medicine Nursing and Health Sciences Monash University Clayton Australia Department of Medicine Faculty of Medicine and Health Sciences The University of Melbourne Royal Melbourne Hospital Melbourne Australia East Bentleigh General Practice Melbourne Australia Emergency Practice Innovation Centre St Vincent’s Hospital Melbourne Australia Formerly Department of Endocrinology St Vincent’s Hospital Melbourne Australia Manningham General Practice Melbourne Australia The Butterfly Foundation Malvern Australia The Gawler Foundation Yarra Junction Australia

Objective: To report our experience of attempting a randomised controlled trial of an intensive lifestyle intervention for early type 2 diabetes delivered in a residential setting. Methods: We established a trial requiring 84 participants (46 standard care and 38 intervention) to detect a 1% difference in HbA1c between intervention and control groups at 12 months, allowing for attrition. Ethics approval was obtained from Monash University. Results: The study was abandoned after five months of consistent promotion due to recruitment failure (four subjects recruited). Conclusion: It appears to be difficult for patients with diabetes to commit to a live-in period of education regarding lifestyle modification as a means of treating the illness. We recommend better education of patients and their doctors about the potential health benefits of lifestyle change to manage type 2 diabetes, and further research into novel methods of delivering lifestyle advice which are both effective and sustainable.

背景全科医生需要面对各种各样的精神疾病患者,包括在文化和语言方面存在巨大差异(CALD)的患者。本研究目的是,了解全科医生在管理CALD精神疾病患者过程中遇到的阻碍和有利条件。方法 2013年5—7月,对墨尔本的10名全科医生进行半结构访谈,根据访谈的主题分别进行数据分析。结果全科医生遇到的阻碍包括:在识别首发症状、告知诊断结果、使用译员服务等方面存在困难。有利条件包括:全科医生和患者的文化背景一致、针对CALD精神疾病患者采取的医疗改进措施、对全科医生和CALD精神疾病患者开展有针对性的继续教育。讨论在全科医生和精神疾病患者文化背景一致的情况下,可以有效促进精神疾病管理。关于使用译员服务、推广医疗改进措施,以提高服务质量,尚需更深入的研究。大多数全科医生认为,有必要在CALD精神疾病患者较多的社区改进心理卫生服务能力。
