1“猪地方性肺炎及其防治控制”专栏二:有关猪肺炎支原体感染诊断方法和流行病学的最新观点显示文摘猪肺炎支原体是猪地方性肺炎(Enzoodc Pneumonia,EP)的主要病原体,本病是一种主要影响肥育猪的慢性呼吸道疾病。尽管人们在控制猪肺炎支原体感染及其带来的不利影响上花费了大量的精力,但是猪地方性肺炎仍继续给全球养猪生产造成重大的经济损失。猪肺炎支原体通常是通过引进亚临床型感染的动物而侵入猪群的,或通过短距离的空气传播发生感染,但后一种情况较少。一旦侵入猪群,猪肺炎支原体可通过与受感染的母猪直接接触而将病原体传给后代或在同圈猪只之间进行传播。用于诊断猪肺炎支原体感染的“黄金标准”技术——细菌学培养非常费劲,通常很少使用。酶联免疫吸附试验和聚合酶链式反应检测方法以及以屠宰场监测或田间剖解为形式的死后检查,是用于调查猪肺炎支原体是否参与了猪呼吸道疾病的最常用技术。这些技术已被用来监测受猪地方性肺炎影响的猪群猪肺炎支原体的临床型和亚临床型感染猪群、免疫猪群或非免疫猪群以及处于不同的生产条件和管理奈件下的猪群的发生情况。猪场水平上的猪地方性肺炎临床过程差异以及猪肺炎支原体疫苗接种效果的差异表明,猪肺炎支原体的不同田间分离株的传播和毒力特性存在差异。本文综述了猪肺炎支原体感染的流行病学最新知识,包括其传播、感染和血清转化动力学,并且还比较了用来监测猪地方性肺炎的各种流行病学方法。Marina Sibila Maria Pieters Thomas Molitor Dominiek Maes Freddy Haesebmuck Joaquim Segal e s 沈权(译) 邵嘉佳(校) 2009国外畜牧学(猪与禽)2009,,3:16
2Factors associated with incomplete small bowel capsule endoscopy studies显示文摘AIM:To identify patient risk factors associated with incomplete small bowel capsule endoscopy(CE) studies.METHODS:Data from all CE procedures performed at St.Paul's Hospital in Vancouver,British Columbia,Canada,between December 2001 and June 2008 were collected and analyzed on a retrospective basis.Data collection for complete and incomplete CE study groups included patient demographics as well as a number of potential risk factors for incomplete CE including indication for the procedure,hospitalization,diabetes mellitus with or without end organ damage,limitations in mobility,renal insufficiency,past history of bowel obstruction,abdominal surgery,abdominal radiation therapy and opiate use.Risk factors were analyzed using a univariable and multivariable logistic regression model.RESULTS:From a total of 535 CE procedures performed,158 were incomplete(29.5%).The univariable analysis showed that CE procedures performed for overt gastrointestinal bleeding(P = 0.002),and for patients with a prior history of abdominal surgery(P = 0.023) or bowel obstruction(P = 0.023) were significantly associated with incomplete CE studies.Patients on opiate medications(P = 0.094) as well as hospitalized patients(P = 0.054) were not statistically significant,but did show a trend towards incomplete CE.The multivariable analysis showed that independent risk factors for an incomplete CE procedure include prior history of bowel obstruction [odds ratios(OR) 2.77,P = 0.02,95% confidence intervals(CI):1.17-6.56] and procedures performed for gastrointestinal bleeding(Occult OR 2.04,P = 0.037,95% CI:1.04-4.02 and Overt OR 2.69,P = 0.002,95% CI:1.44-5.05).Patients with a prior history of abdominal surgery(OR 1.46,P = 0.068,95% CI:0.97-2.19),those taking opiate medications(OR 1.54,P = 0.15,95% CI:0.86-2.76) and hospitalized patients(OR 1.82,P = 0.124,95% CI:0.85-3.93) showed a trend towards statistical significance.CONCLUSION:We have identified a number of risk factors for incomplete CE procedures that can be used to risk-stratify patients and guide interventions to improve completion rates.Mitchell M Lee Andrew Jacques Eric Lam Ricky Kwok Pardis Lakzadeh Ajit Sandhar Brandon Segal Sigrid Svarta Joanna Law Robert Enns 2010World Journal of Gastroenterology2010,16,42:10

4Vaccine-induced autoimmunity: the role of molecular mimicry and immune crossreaction显示文摘Since the early 1800s vaccines have saved numerous lives by preventing lethal infections.However,during the past two decades,there has been growing awareness of possible adverse events associated with vaccinations,cultivating heated debates and leading to significant fluctuations in vaccination rates.It is therefore pertinent for the scientific community to seriously address public concern of adverse effects of vaccines to regain public trust in these important medical interventions.Such adverse reactions to vaccines may be viewed as a result of the interaction between susceptibility of the vaccinated subject and various vaccine components.Among the implicated mechanisms for these reactions is molecular mimicry.Molecular mimicry refers to a significant similarity between certain pathogenic elements contained in the vaccine and specific human proteins.This similarity may lead to immune crossreactivity,wherein the reaction of the immune system towards the pathogenic antigens may harm the similar human proteins,essentially causing autoimmune disease.In this review,we address the concept of molecular mimicry and its application in explaining post vaccination autoimmune phenomena.We further review the principal examples of the influenza,hepatitis B,and human papilloma virus vaccines,all suspected to induce autoimmunity via molecular mimicry.Finally,we refer to possible implications on the potential future development of better,safer vaccines.Yahel Segal Yehuda Shoenfeld 2018Cellular & Molecular Immunology2018,15,6:6
5副猪嗜血杆菌感染诊断方法和最新基因分型方法的研究进展显示文摘副猪嗜血杆菌可引起猪格拉塞病和其它许多疾病,对与该菌有关的疾病进行诊断通常依赖于临床症状、病理变化和细菌分离,但由于有无毒菌株(nonvirulentstrain)的存在及其在健康仔猪上呼吸道上的早期定殖,使得对该菌的诊断变得较为复杂。而且,在同一猪场甚至是同一只猪体内可能存在多种不同的菌株,因此确定可导致临床发病的特定菌株显得尤为重要。最近,科研人员开发了一些针对副猪嗜血杆菌的基因分型方法,目的是确定该菌的基因型与其毒力强度之间的关系。由于缺乏副猪嗜血杆菌完整基因组序列及其致病因子(viru-lencefactor)的知识,因此将副猪嗜血杆菌的基因型与其毒力联系起来极富挑战性。李艳 刘静 Alex Olvera Joaquim Segales 2008国外畜牧学(猪与禽)2008,28,5:5

9SEPRAN: A Versatile Finite-Element Package for a Wide Variety of Problems in Geosciences显示文摘Numerical modelling of geological processes,such as mantle convection,flow in porous media,and geothermal heat transfer,has become quite common with the increase in computing and the availability of usable software. Today modelling these dynamical processes entails the solving of the governing equations involving the mass,momentum,energy and chemical transport. These equations represent partial differential equations and must be solved on powerful enough computers because they require sufficient spatial and temporal resolution to be useful. We describe here the salient and outstanding features of the SEPRAN software package,developed in the Netherlands,as a case study for a robust and user-friendly software,which the geological community can utilize in handling many thermal-mechanical-chemical problems found in geology,which will include geothermal situations,where many types of partial differential equations must be solved at the same time with thermodynamical input parameters.Arie van den Berg Guus Segal David A.Yuen 2015Journal of Earth Science2015,26,1:3

11Systematic review of macular ganglion cell complex analysis using spectral domain optical coherence tomography for glaucoma assessment显示文摘AIM: To review the use of spectral domain optical coherence tomography(SD-OCT) for macular retinal ganglion cells(RGC) and ganglion cell complex(GCC) measurement in glaucoma assessment, specifically for early detection and detection of disease progression. METHODS: A systematic review was performed by searching Pub Med, Medline, and Web of Science for articles published in English through July 2014 describing the various macular SD-OCT scanning strategies developed for glaucoma assessment. The review focused on papers evaluating the use of macular RGC/GCC SDOCT to detect early glaucoma and its progression. The search included keywords corresponding to the index test(macular ganglion cell/RGC/GCC/Spectral domain OCT), the target condition(glaucoma), and diagnostic performance. The RGC/GCC SD-OCT scanning strategies used to assess glaucoma of most commonly used SD-OCT instruments were described and compared. These included the Cirrus high definition-OCT(Carl Zeiss Meditec, Inc., Dublin, CA, United States), RTVue(Optovue, Inc., Fremont, CA, United States), Spectralis(Heidelberg Engineering, Heidelberg, Germany) and the 3D OCT 2000(Topcon Corporation, Tokyo, Japan). Studies focusing on the ability of RGC/GCC SD-OCT to detect early glaucomatous damage and on the correlation between glaucomatous progression and RGC/GCC measurement by SD-OCT were reviewed.RESULTS: According to the literature, macular RGC/GCC SD-OCT has high diagnostic power of preperimetric glaucoma, reliable discrimination ability to differentiate between healthy eyes and glaucomatous eyes, with good correlation with visual filed damage. The current data suggests that it may serve as a sensitive detection tool for glaucomatous structural progression even with mild functional progression as the rate of change of RGC/GCC thickness was found to be significantly higher in progressing than in stable eyes. Glaucoma assessment with RGC/GCC SD-OCT was comparable with and sometimes better than circumpapillary retinal nerve fiber layer thickness measurement.CONCLUSION: An increasing body of evidence supports using macular RGC/GCC thickness as an indicator for early glaucoma. This might be a useful tool for monitoring disease progression.Amit Meshi Dafna Goldenberg Sharon Armarnik Ori Segal Noa Geffen 2015World Journal of Ophthalmology2015,5,2:3
12The emergency department length of stay: Is the time running out?显示文摘Purpose: To examine the relationships between emergency department length of stay (EDLOS) with hospital length of stay (HLOS) and clinical outcome in hemodynamically stable trauma patients. Methods: Prospective data collected for 2 years from consecutive trauma patients admitted to the trauma resuscitation bay. Only stable blunt trauma patients with appropriate trauma triage criteria requiring trauma teamactivationwere included in the study. EDLOSwas determined short if patient spent less than 2 h in the emergency department (ER) and long for more than 2 h. Results: A total of 248 patients were enrolled in the study. The mean total EDLOS was 125 min (range 78 e180). Injury severity score (ISS) were significantly higher in the long EDLOS group (17 ± 13 versus 11 ± 9, p < 0.001). However, when leveled according to ISS, there were no differences in mean in diagnostic workup, admission rate to intensive care unit (ICU) or HLOS between the short and long EDLOS groups. Conclusion: EDLOS is not a significant parameter for HLOS in stable trauma patients.Alexander Becker Gil Segal Yuri Berlin Dan Hershko 2019Chinese Journal of Traumatology2019,22,3:2
