1面向21世纪的卒中新定义:美国心脏病学会和美国卒中学会声明显示文摘尽管脑血管病有着全球性影响且对其病理生理学的认识有了很多进步,但是'卒中'这一术语在临床实践、临床研究或公共卫生评估中的定义却不一致。传统的定义依据于临床,却没有考虑到科学技术的进步。美国心脏协会(AHA)和美国卒中协会(ASA)卒中分会组织了写作小组,为21世纪卒中新定义撰写专家共识性声明。中枢神经系统(CNS)梗死,指由缺血所导致的脑、脊髓或视网膜的细胞死亡,是基于持续性损害的神经病理学、神经影像学和(或)临床证据。CNS梗死表现为一个临床谱:缺血性卒中特指伴有明显症状的CNS梗死,而静息性梗死根据定义指未引起已知的症状的梗死。卒中也还包括脑出血和蛛网膜下腔出血。新定义的卒中结合了临床和组织学标准,可被用于实践、研究和公共卫生评估。俞羚 董荃 宋叶平 江静雯 李卉 刘亮贤 苏爱萍 李焰生 Sacco RL Kasner SE Broderick JP Caplan LR Connors JJ Culebras A Elkind MS George MG Hamdan AD Higashida RT Hoh BL Janis LS Kase CS Kleindorfer DO Lee JM Moseley ME Peterson ED Turan TN Valderrama AL Vinters HV 2013神经病学与神经康复学杂志2013,10,2:188

3When worlds collide: Th17 and Treg cells in cancer and autoimmunity显示文摘The balance between Th17 cells and regulatory T cells(Tregs)has emerged as a prominent factor in regulating autoimmunity and cancer.Th17 cells are vital for host defense against pathogens but have also been implicated in causing autoimmune disorders and cancer,though their role in carcinogenesis is less well understood.Tregs are required for self-tolerance and defense against autoimmunity and often correlate with cancer progression.This review addresses the importance of a functional homeostasis between these two subsets in health and the consequences of its disruption when these forces collide in disease.Importantly,we discuss the ability of Th17 cells to mediate cancer regression in immunotherapy,including adoptive transfer and checkpoint blockade therapy,and the therapeutic possibilities of purposefully offsetting the Th17/Treg balance to treat patients with cancer as well as those with autoimmune diseases.Hannah M.Knochelmann Connor J.Dwyer Stefanie R.Bailey Sierra M.Amaya Dirk M.Elston Joni M.Mazza-Mc.Crann Chrystal M.Paulos 2018Cellular & Molecular Immunology2018,15,5:50
4利用DEM提取地貌指数的方法述评显示文摘介绍了几个广泛应用于水文科学的流域地貌指数(包括地表坡度、流量分配系数、单宽集水面积、集水面积以及湿度指数)的计算方法,阐述了这些地貌指数在水文科学中所代表的物理意义和对流域水文过程空间分布的描述能力。对了解流域地貌对降雨径流的影响,揭示产汇流过程的物理机制,研制和开发分布式水文物理模型均有重要意义。熊立华 郭生练 Kieran M.O Connor 2002水科学进展2002,13,6:30
5综合性卒中中心医疗质量的度量标准:对脑卒中联盟综合性卒中中心推荐意见的详细随访美国心脏协会/美国卒中协会对医疗专业人员的声明显示文摘背景卒中是一种主要的残疾和死亡原因。脑卒巾联盟提议,建立初级卒中中心(primary stroke center,PSC)和综合性卒中中心(comprehensive stroke center,csc)以分别为需要基本或高级下预的卒中患者提供适当的医疗服务。从2003年开始,美国医疗卫生机构认证联合委员会和各州已指定了一些PSC,目前正在考虑CSC的指定工作。为了推进该过程,我们提出了一套CSC应追踪监测医疗质量并促进质量改进的标准和相关数据。方法和结果我们分析了现有指南、综述和其他文献,以识别区分CSC与PSC的主要特征;起草了一套标准和相关数据元素,以评价这些卒中医疗方面的关键部分;然后通过反复修改达成共识。我们提出的这套标准和相关数据元素,涵盖了CSC内缺血性脯血管病、非外伤性蛛网膜下腔出血和腩出血患者专、№医疗的主要方面。结论我们提出这套标准,旨在为CSC的标准化数据采集提供一个框架,以促进当地医疗质量改进,并允许对来自不同CSC的数据进行合并分析。这将有助于将来CSC国家执行标准的制定。何晟(译) 蔡可夫(译) 张元媛(译) 胡旻婧(译) 倪耀辉(译) 芮瑛(译) 柯开富(译) Dana Leifer Dawn M.

14Computed tomography and patient risk:Facts,perceptions and uncertainties显示文摘Since its introduction in the 1970s, computed tomography(CT) has revolutionized diagnostic decision-making. One of the major concerns associated with the widespread use of CT is the associated increased radiation exposure incurred by patients. The link between ionizing radiation and the subsequent development of neoplasia has been largely based on extrapolating data from studies of survivors of the atomic bombs dropped in Japan in 1945 and on assessments of the increased relative risk of neoplasia in those occupationally exposed to radiation within the nuclear industry. However, the association between exposure to low-dose radiation from diagnostic imaging examinations and oncogenesis remains unclear. With improved technology, significant advances have already been achieved with regards to radiation dose reduction. There are several dose optimization strategies available that may be readily employed including omitting unnecessary images at the ends of acquired series, minimizing the number of phases acquired, and the use of automated exposure control as opposed to fixed tube current techniques. In addition, new image reconstruction techniques that reduce radiation dose have been developed in recent years with promising results. These techniques use iterative reconstruction algorithms to attain diagnostic quality images with reduced image noise at lower radiation doses.Stephen P Power Fiachra Moloney Maria Twomey Karl James Owen J O'Connor Michael M Maher 2016World Journal of Radiology2016,8,12:7
15磨矿介质材质与捕收剂添加方式对某铜镍硫化矿浮选的影响显示文摘通过磨矿和浮选试验研究了低碳钢和不锈钢两种磨矿介质与捕收剂添加方式对某铜镍硫化矿(Nkomati矿)浮选的影响。试验研究使用实验室用圆筒形棒磨机和机械搅拌式挂槽浮选机完成,通过浮选水回收率、精矿产率和有用矿物回收率分析了磨矿介质和捕收剂添加方式对铜镍硫化物浮选行为的影响。研究中对矿浆pH值、氧化还原电位(Eh)和溶解氧(Do)等溶液化学性质进行了测定,以考察磨矿介质及捕收剂添加方式对溶液化学性质的影响。磨矿介质对Nkomati矿的矿浆溶液化学性质和浮选行为具有显著影响,经低碳钢磨矿后,具有较高的铜、镍和磁黄铁矿回收率,EDTA可浸出铁的含量更高,Do值更低。不同磨矿介质磨矿条件下,捕收剂添加方式对铜镍矿浮选的影响规律不同,低碳钢磨矿时,捕收剂添加在浮选槽中的铜回收率较高;不锈钢磨矿时,捕收剂添加在磨机中的铜和镍的回收率较高。宋振国 K Corin J G Wiese C T O'Connor 2017矿产保护与利用2017,37,6:6
16Gastroenterologist perceptions of faecal microbiota transplantation显示文摘AIM: To explore gastroenterologist perceptions towards and experience with faecal microbiota transplantation(FMT).METHODS: A questionnaire survey consisting of 17 questions was created to assess gastroenterologists' attitude towards and experience with FMT. This was anonymously distributed in hard copy format amongst attendees at gastroenterology meetings in Australia between October 2013 and April 2014. Basic descriptive statistical analyses were performed.RESULTS: Fifty-two clinicians participated. Twenty one percent had previously referred patients for FMT,8% more than once. Ninety percent would refer patients with Clostridium difficile infection(CDI) for FMT if easily available,37% for ulcerative colitis,13% for Crohn's disease and 6% for irritable bowel syndrome. Six percent would not refer any indication,including recurrent CDI. Eighty-six percent would enroll patients in FMT clinical trials. Thirty-seven percent considered the optimal mode of FMT administration transcolonoscopic,17% nasoduodenal,13% enema and 8% oral capsule. The greatest concerns regarding FMT were: 42% lack of evidence,12% infection risk,10% non infectious adverse effects/lack of safety data,10% aesthetic,10% lack of efficacy,4% disease exacerbation,and 2% inappropriate use; 6% had no concerns. Seventy seven percent believed there is a lack of accessibility while 52% had an interest in learning how to provide FMT. Only 6% offered FMT at their institution.CONCLUSION: Despite general enthusiasm,most gastroenterologists have limited experience with,or access to,FMT. The greatest concerns were lack of supportive evidence and safety issues. However a significant proportion would refer indications other than CDI for FMT despite insufficient evidence. These data provide guidance on where education and training are required.Sudarshan Paramsothy Alissa J Walsh Thomas Borody Douglas Samuel Johan van den Bogaerde Rupert WL Leong Susan Connor Watson Ng Hazel M Mitchell Nadeem O Kaakoush Michael A Kamm 2015World Journal of Gastroenterology2015,21,38:5

18Anemia and iron deficiency in gastrointestinal and liver conditions显示文摘Iron deficiency anemia(IDA) is associated with a number of pathological gastrointestinal conditions other than inflammatory bowel disease, and also with liver disorders. Different factors such as chronic bleeding, malabsorption and inflammation may contribute to IDA. Although patients with symptoms of anemia are frequently referred to gastroenterologists, the approach to diagnosis and selection of treatment as well as follow-up measures is not standardized and suboptimal. Iron deficiency, even without anemia, can substantially impact physical and cognitive function and reduce quality of life. Therefore, regular iron status assessment and awareness of the clinical consequences of impaired iron status are critical. While the range of options for treatment of IDA is increasing due to the availability of effective and well-tolerated parenteral iron preparations, a comprehensive overview of IDA and its therapy in patients with gastrointestinal conditions is currently lacking. Furthermore, definitions and assessment of iron status lack harmonization and there is a paucity of expert guidelines on this topic. This review summarizes current thinking concerning IDA as a common co-morbidity in specific gastrointestinal and liver disorders, and thus encourages a more unified treatment approach to anemia and iron deficiency, while offering gastroenterologists guidance on treatment options for IDA in everyday clinical practice.Jürgen Stein Susan Connor Garth Virgin David Eng Hui Ong Lisandro Pereyra 2016World Journal of Gastroenterology2016,22,35:5

20A new species from an ornithuromorph(Aves: Ornithothoraces)dominated locality of the Jehol Biota显示文摘We report on a new species of ornithuromorph bird, Iteravis huchzermeyeri gen. et sp. nov., from the previously unreported Sihedang locality of the Lower Cretaceous Yixian Formation, the oldest ornithuromorph bearing deposit in the world. Unlike most other Cretaceous localities, specimens from this new quarry are largely referable to Ornithuromorpha, similar to the Lower Cretaceous Aptian Xiagou Formation in Gansu Province. Also similar to the Xiagou avifauna, the fauna at Sihedang is largely dominated by a single taxon(described here).Differences in faunal dominance may suggest the Sihedang records a unique ecological habitat. This may also explain the dominance of Gansus in the younger Xiagou Formation locality and suggests that previous hypotheses regarding the shift in dominance between Enantiornithes and Ornithuromorpha need to be reassessed in terms of potential ecological biases due to limited sampling. Furthermore, the recognition of an ornithuromorph dominated locality in the Sihedang significantly weakens the signal of such an inferred trend. Compared to most Jehol birds, the new specimen is relatively better preserved in three dimensions revealing morphological details of the skeleton, as well as preserves feather impressions including a rectricial morphology previously unknown among Mesozoic birds.Shuang Zhou Jingmai K.O'Connor Min Wang 2014Chinese Science Bulletin2014,59,36:4
