4冠状动脉内影像学临床应用专家共识(第一部分):对冠状动脉介入治疗的指导与优化显示文摘欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。Lorenz Raber Gary S Mintz Konstantinos C Koskinas Thomas W Johnson Niels R Holm Yoshinubo Onuma Maria D Radu Michael Joner Bo Yu Haibo Jia Nicolas Meneveau Jose M.de la Torre Hemandez Javier Escaned Jonathan Hill Francesco Prati Antonio Colombo Carlo di Mario Evelyn Regar Davide Capodanno William Wijns Robert A Byme Giulio Guagliumi 2019中华心血管病杂志2019,47,1:17
5板块构造机制在显生宙初期发生转变显示文摘虽然目前对于板块构造何时成为主要构造机制存在争议,但是研究者普遍认为在古太古代已经完成转变。元古代时期,哥伦比亚超大陆向罗迪尼亚超大陆的转换,并未发生超大陆的完全裂解和聚合,而是岩石圈和环境的相对稳定期。相比之下,成冰期至今则发育有大量的被动大陆边缘,以及在425~225 Ma期间大幅增加的裂谷和大陆岛弧长度,表明存在与潘吉亚超大陆形成密切相关的激烈板块构造活动。袁超(编译) Brown M Kirkland C L Johnson T E 2020矿物岩石地球化学通报2020,39,4:9

8Clinical update for the diagnosis and treatment of Clostridium difficile infection显示文摘Clostridium difficile infection(CDI)presents a rapidly evolving challenge in the battle against hospitalacquired infections.Recent advances in CDI diagnosis and management include rapid changes in diagnostic approach with the introduction of newer tests,such as detection of glutamate dehydrogenase in stool and polymerase chain reaction to detect the gene for toxin production,which will soon revolutionize the diagnostic approach to CDI.New medications and multiple medical society guidelines have introduced changing concepts in the definitions of severity of CDI and the choice of therapeutic agents,while rapid expansion of data on the efficacy of fecal microbiota transplantation heralds a revolutionary change in the management of patients suffering multiple relapses of CDI.Through a comprehensive review of current medical literature,this article aims to offer an intensive review of the current state of CDI diagnosis,discuss the strengths and limitations of available laboratory tests,compare both current and future treatments options and offer recommendations for best practice strategies.Edward C Oldfield Ⅳ Edward C Oldfield Ⅲ David A Johnson 2014World Journal of Gastrointestinal Pharmacology and Therapeutics2014,5,1:6

11Osteopontin: a leading candidate adhesion molecule for implantation in pigs and sheep显示文摘Osteopontin(OPN; also known as Secreted Phosphoprotein 1, SPP1) is a secreted extra-cellular matrix(ECM) protein that binds to a variety of cell surface integrins to stimulate cell-cell and cell-ECM adhesion and communication. It is generally accepted that OPN interacts with apically expressed integrin receptors on the uterine luminal epithelium(LE)and conceptus trophectoderm to attach the conceptus to the uterus for implantation. Research conducted with pigs and sheep has significantly advanced understanding of the role(s) of OPN during implantation through exploitation of the prolonged peri-implantation period of pregnancy when elongating conceptuses are free within the uterine lumen requiring extensive paracrine signaling between conceptus and endometrium. This is followed by a protracted and incremental attachment cascade of trophectoderm to uterine LE during implantation, and development of a true epitheliochorial or synepitheliochorial placenta exhibited by pigs and sheep, respectively. In pigs, implanting conceptuses secrete estrogens which induce the synthesis and secretion of OPN in adjacent uterine LE. OPN then binds to αvβ6 integrin receptors on trophectoderm, and the αvβ3 integrin receptors on uterine LE to bridge conceptus attachment to uterine LE for implantation. In sheep, implanting conceptuses secrete interferon tau that prolongs the lifespan of CL. Progesterone released by CL then induces OPN synthesis and secretion from the endometrial GE into the uterine lumen where OPN binds integrins expressed on trophectoderm(αvβ3) and uterine LE(identity of specific integrins unknown) to adhere the conceptus to the uterus for implantation. OPN binding to the αvβ3 integrin receptor on ovine trophectoderm cells induces in vitro focal adhesion assembly, a prerequisite for adhesion and migration of trophectoderm, through activation of: 1) P70S6 K via crosstalk between FRAP1/MTOR and MAPK pathways; 2) MTOR,PI3 K, MAPK3/MAPK1(Erk1/2) and MAPK14(p38) signaling to stimulate trohectoderm cell migration; and 3) focal adhesion assembly and myosin II motor activity to induce migration of trophectoderm cells. Further large in vivo focal adhesions assemble at the uterine-placental interface of both pigs and sheep and identify the involvement of sizable mechanical forces at this interface during discrete periods of trophoblast migration, attachment and placentation in both species.Greg A Johnson Robert C Burghardt Fuller W Bazer 2015Journal of Animal Science and Biotechnology2015,6,2:4
12Uterine biology in pigs and sheep显示文摘There is a dialogue between the developing conceptus (embryo-fetus and associated placental membranes) and maternal uterus which must be established during the peri-implantation period for pregnancy recognition signaling, implantation, regulation of gene expression by uterine epithelial and stromal cells, placentation and exchange of nutrients and gases. The uterus provide a microenvironment in which molecules secreted by uterine epithelia or transported into the uterine lumen represent histotroph required for growth and development of the conceptus and receptivity of the uterus to implantation. Pregnancy recognition signaling mechanisms sustain the functional lifespan of the corpora lutea (CL) which produce progesterone, the hormone of pregnancy essential for uterine functions that support implantation and placentation required for a successful outcome of pregnancy. It is within the peri-implantation period that most embryonic deaths occur due to deficiencies attributed to uterine functions or failure of the conceptus to develop appropriately, signal pregnancy recognition and/or undergo implantation and placentation. With proper placentation, the fetal fluids and fetal membranes each have unique functions to ensure hematotrophic and histotrophic nutrition in support of growth and development of the fetus. The endocrine status of the pregnant female and her nutritional status are critical for successful establishment and maintenance of pregnancy. This review addresses the complexity of key mechanisms that are characteristic of successful reproduction in sheep and pigs and gaps in knowledge that must be the subject of research in order to enhance fertility and reproductive health of livestock species.Fuller W Bazer Gwonhwa Song Jinyoung Kim Kathrin A Dunlap Michael Carey Satterfield Gregory A Johnson Robert C Burghardt Guoyao Wu 2012Journal of Animal Science and Biotechnology2012,3,3:3

17Celiac disease:Management of persistent symptoms in patients on a gluten-free diet显示文摘AIM:To investigate all patients referred to our center with non-responsive celiac disease (NRCD),to establish a cause for their continued symptoms.METHODS:We assessed all patients referred to our center with non-responsive celiac disease over an 18-mo period.These individuals were investigated to establish the eitiology of their continued symptoms.The patients were first seen in clinic where a thorough history and examination were performed with routine blood work including tissue transglutaminase antibody measurement.They were also referred to a specialist gastroenterology dietician to try to identift any lapses in the diet and sources of hidden gluten ingestion.A repeat small intestinal biopsy was also performed and compared to biopsies from the referring hospital where possible.Colonoscopy,lactulose hydrogen breath testing,pancreolauryl testing and computed tomography scan of the abdomen were undertaken if the symptoms persisted.Their clinical progress was followed over a minimum of 2 years.RESULTS:One hundred and twelve consecutive patients were referred with NRCD.Twelve were found not to have celiac disease (CD).Of the remaining 100 patients,45% were not adequately adhering to a strict gluten-free diet,with 24 (53%) found to be inadvertently ingesting gluten,and 21 (47%) admitting noncompliance.Microscopic colitis was diagnosed in 12% and small bowel bacterial overgrowth in 9%.Refractory CD was diagnosed in 9%.Three of these were diagnosed with intestinal lymphoma.After 2 years,78 patients remained well,eight had continuing symptoms,and four had died.CONCLUSION:In individuals with NRCD,a remediable cause can be found in 90%:with continued gluten ingestion as the leading cause.We propose an algorithm for investigation.David H Dewar Suzanne C Donnelly Simon D McLaughlin Matthew W Johnson H Julia Ellis Paul J Ciclitira 2012World Journal of Gastroenterology2012,18,12:2
