1Adult iatrogenic ureteral injury and strictureeincidence and treatment strategies显示文摘Iatrogenic ureteral injuries and strictures are relatively common complication of pelvic surgery and radiation treatment.Left untreated they are associated with severe shortand long-term complications such as urinoma,septic state,renal failure,and loss of a renal unit.Treatment depends on timing of diagnosis,as well as extent of injury,and ranges from simple endoscopic management to complex surgical reconstruction under usage of pedicled grafts.While recent advances in ureteral tissue engineering are promising the topic is still underreported.Historically a domain of open surgery,laparoscopic and robotic-assisted approaches have proven their feasibility in small case series,and are increasingly being utilized as means of reconstructive surgery.This review aims to give an outline of incidence and treatment of ureteral injuries and strictures in light of the latest advances.Philipp Gild Luis AKluth Malte WVetterlein Oliver Engel Felix KHChun Margit Fisch 2018Asian Journal of Urology2018,5,2:14
2鳞状上皮细胞癌抗原水平新检测方法在宫颈癌、肺癌和头颈部癌鉴别诊断中的性能及临床表现显示文摘鳞状上皮细胞癌抗原水平在鳞状上皮细胞癌中通常升高。这项多中心研究评估了一种新的Elecsys?鳞状上皮细胞癌检测的检测性能,该检测方法是以等摩尔方式测量血清鳞状上皮细胞癌抗原1和2的水平,并研究了鳞状上皮细胞癌抗原用于宫颈癌、肺癌和头颈部鳞状上皮细胞癌鉴别诊断的潜能。在欧洲三个研究中心进行了精确度和方法学比较实验。健康人群的参考区间使用来自欧洲和中国人群的样本确定的。鉴别诊断试验确定了鳞状上皮细胞癌抗原水平能否将宫颈癌、肺癌或头颈癌与表观健康的、良性的或其他恶性群组区分开来。根据95%特异性下的鳞状上皮细胞癌抗原水平计算出鳞状上皮细胞癌抗原医学截断值。9个分析浓度的重复性变异系数<5.3%,中间精密变异系数<0.3%。方法学比较显示,与Architect和Kryptor系统具有很好的相关性(斜率分别为1.1和1.5)。表观健康人群的第95百分位数的参考区间为2.3 ng/m L(95%置信区间:1.9-3.8;欧洲队列,n=153)和2.7 ng/m L(95%置信区间:2.2-3.3;中国队列,n=146)。最佳的鉴别诊断结果见于宫颈鳞状上皮细胞癌:受试者工作特征曲线分析显示鳞状上皮细胞癌抗原水平(2.9 ng/m L的医学截断值)鉴别宫颈鳞状上皮细胞癌(n=127)与表观健康女性(n=286;曲线下面积:86.2%;95%置信区间:81.8-90.6;灵敏度:61.4%;特异性:95.6%),良性疾病(n=187;曲线下面积:86.3%;95%置信区间:81.2-91.3;灵敏度:61.4%;特异性:95.0%)和其他宫颈癌(n=157;曲线下面积:78.9%;95%置信区间:70.8-87.1;灵敏度:61.4%;特异性:86.7%)。鳞状上皮细胞癌还可帮助鉴别诊断肺癌。Elecsys鳞状上皮细胞癌检测技术在宫颈鳞状上皮细胞癌的临床实践中表现出了良好的性能,适合用于鉴别诊断。Stefan HOLDENRIEDER Rafael MOLINA Ling QIU Xiuyi ZHI Sandra RUTZ Christine ENGEL Pia KASPER- SAUER Farshid DAYYANI Catharina Mkorse 2018中国肺癌杂志2018,21,7:13
3Diagnosis of gastrointestinal bleeding: A practical guide for clinicians显示文摘Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians.Bong Sik Matthew Kim Bob T Li Alexander Engel Jaswinder S Samra Stephen Clarke Ian D Norton Angela E Li 2014World Journal of Gastrointestinal Pathophysiology2014,5,4:13
4CuZn37黄铜板料微塑性成形中的尺寸效应研究显示文摘为研究金属微塑性成形特点,对厚度不同及粗细两种晶粒尺寸的黄铜箔试样进行了单向拉伸和微弯曲实验,并采用经典塑性理论和应变梯度理论对弯曲回弹角进行了预测.粗晶粒板料试样单向拉伸实验表明,CuZn37黄铜的硬化曲线存在一种明显的尺寸效应,即板料厚度越小,屈服强度越高.弯曲回弹实验结果也存在另一种明显的尺寸效应现象,即板料厚度越小,回弹角越大.对这两种尺寸效应产生的原因进行了分析,指出应变梯度硬化对微成形工艺过程有重要影响.李河宗 董湘怀 王倩 申昱 DIEHL A HAGENAH H ENGEL U MERKLEIN M 2011材料科学与工艺2011,19,4:12
5Responses of an old-field plant community to interacting factors of elevated[CO_(2)],warming,and soil moisture显示文摘Aims The direct effects of atmospheric and climatic change factors—atmospheric[CO_(2)],air temperature and changes in precipitation—can shape plant community composition and alter ecosystem function.It is essential to understand how these factors interact to make better predictions about how ecosystems may respond to change.We investigated the direct and interactive effects of[CO_(2)],warming and altered soil moisture in open-top chambers(OTCs)enclosing a constructed old-field community to test how these factors shape plant communities.Materials and methods The experimental facility in Oak Ridge,TN,USA,made use of 4-m diameter OTCs and rain shelters to manipulate[CO_(2)](ambient,ambient+300 ppm),air temperature(ambient,ambient+3.5C)and soil moisture(wet,dry).The plant communities within the chambers comprised seven common old-field species,including grasses,forbs and legumes.We tracked foliar cover for each species and calculated community richness,evenness and diversity from 2003 to 2005.Important findings This work resulted in three main findings:(1)warming had speciesspecific effects on foliar cover that varied through time and were altered by soil moisture treatments;(2)[CO_(2)]had little effect on individual species or the community;(3)diversity,evenness and richness were influenced most by soil moisture,primarily reflecting the response of one dominant species.We conclude that individualistic species responses to atmospheric and climatic change can alter community composition and that plant populations and communities should be considered as part of analyses of terrestrial ecosystem response to climate change.However,prediction of plant community responses may be difficult given interactions between factors and changes in response through time.E.Cayenne Engel Jake F.Weltzin Richard J.Norby Aimee T.Classen 2009Journal of Plant Ecology2009,2,1:8

7Artificial intelligence in gastroenterology: A state-of-the-art review显示文摘The development of artificial intelligence(AI)has increased dramatically in the last 20 years,with clinical applications progressively being explored for most of the medical specialties.The field of gastroenterology and hepatology,substantially reliant on vast amounts of imaging studies,is not an exception.The clinical applications of AI systems in this field include the identification of premalignant or malignant lesions(e.g.,identification of dysplasia or esophageal adenocarcinoma in Barrett’s esophagus,pancreatic malignancies),detection of lesions(e.g.,polyp identification and classification,small-bowel bleeding lesion on capsule endoscopy,pancreatic cystic lesions),development of objective scoring systems for risk stratification,predicting disease prognosis or treatment response[e.g.,determining survival in patients post-resection of hepatocellular carcinoma),determining which patients with inflammatory bowel disease(IBD)will benefit from biologic therapy],or evaluation of metrics such as bowel preparation score or quality of endoscopic examination.The objective of this comprehensive review is to analyze the available AI-related studies pertaining to the entirety of the gastrointestinal tract,including the upper,middle and lower tracts;IBD;the hepatobiliary system;and the pancreas,discussing the findings and clinical applications,as well as outlining the current limitations and future directions in this field.Paul T Kröner Megan ML Engels Benjamin S Glicksberg Kipp W Johnson Obaie Mzaik Jeanin E van Hooft Michael B Wallace Hashem B El-Serag Chayakrit Krittanawong 2021World Journal of Gastroenterology2021,27,40:6
8Neglected tropical diseases:an effective global response to local poverty-related disease priorities显示文摘Background:Neglected tropical diseases(NTDs)have long been overlooked in the global health agenda.They are intimately related to poverty,cause important local burdens of disease,but individually do not represent global priorities.Yet,NTDs were estimated to affect close to 2 billion people at the turn of the millennium,with a collective burden equivalent to HIV/AIDS,tuberculosis,or malaria.A global response was therefore warranted.Main text:The World Health Organization(WHO)conceived an innovative strategy in the early 2000s to combat NTDs as a group of diseases,based on a combination of five public health interventions.Access to essential NTD medicines has hugely improved thanks to strong public-private partnership involving the pharmaceutical sector.The combination of a WHO NTD roadmap with clear targets to be achieved by 2020 and game-changing partner commitments endorsed in the London Declaration on Neglected Tropical Diseases,have led to unprecedented progress in the implementation of large-scale preventive treatment,case management and care of NTDs.The coming decade will see as challenges the mainstreaming of these NTD interventions into Universal Health Coverage and the coordination with other sectors to get to the roots of poverty and scale up transmissionbreaking interventions.Chinese expertise with the elimination of multiple NTDs,together with poverty reduction and intersectoral action piloted by municipalities and local governments,can serve as a model for the latter.The international community will also need to keep a specific focus on NTDs in order to further steer this global response,manage the scaling up and sustainment of NTD interventions globally,and develop novel products and implementation strategies for NTDs that are still lagging behind.Conclusions:The year 2020 will be crucial for the future of the global response to NTDs.Progress against the 2020 roadmap targets will be assessed,a new 2021–2030 NTD roadmap will be launched,and the London Declaration commitments will need to be renewed.It is hoped that during the coming decade the global response will be able to further build on today’s successes,align with the new global health and development frameworks,but also keep focused attention on NTDs and mobilize enough resources to see the effort effectively through to 2030.Dirk Engels Xiao-Nong Zhou 2020Infectious Diseases of Poverty2020,9,1:4
9采用先进的深枪喂钙线钢包处理法改进工艺控制及提高钢质量显示文摘<正> 在过去的九年中,在冶炼高质量钢方面,喂线技术作为一种实现钙处理的经济有效方法,已经得到了世界范围的广泛认可。1975年,Pfizer通过采用Pferrocal~*包芯线在北美首创了喂线技术。这些早期的试验结果不仅表明了喂线的有效性,而且还对流体力学和热力学条件进行了限定,特别是需要使用纯钙的条件。MARK J ENGEL 张开坚 1993钢铁钒钛1993,14,1:4
10Mesozoic giant fleas from northeastern China (Siphonaptera):Taxonomy and implications for palaeodiversity显示文摘The recently discovered definite giant fleas from the Middle Jurassic Daohugou fauna and the Early Cretaceous Jehol fauna of northeastern China represent significant evidence for understanding ectoparasitism in the Mesozoic as well as the evolution of these giant blood feeders with their putative hosts (i.e. hairy or feathered vertebrates). On the basis of seven well-preserved specimens from Daohugou and Huangbanjigou we analyse the systematic classification of these primitive fleas, establishing two new genera and three new species as Pseudopulex wangi sp. nov., Hadropsylla sinica gen. et sp. nov., and Tyrannopsylla beipiaoensis gen. et sp. nov. All of them are assigned to the extinct siphonapteran family Pseudopulicidae, while the Early Cretaceous genus Tarwinia is transferred to Tarwiniidae fam. nov. The basal morphological disparities of Siphonaptera in the Mesozoic are evidenced by the occurrence of at least three distinct groups (pseudopulicids, tarwiniids, and saurophthirids). These disparate morphologies likely indicate adaptations to different hosts.HUANG DiYing ENGEL Michael S CAI ChenYang NEL André 2013Chinese Science Bulletin2013,58,14:4
11On tolerability and safety of a maintenance treatment with 6-thioguanine in azathioprineor 6-mercaptopurine intolerant IBD patients显示文摘AIM: To determine the tolerability and safety profile of a low-dose maintenance therapy with 6-TG in azathioprine (AZA) or 6-mercaptopurine (6-MP) intolerant inflammatory bowel disease (IBD) patients over a treatment period of at least 1 year.METHODS: Database analysis.RESULTS: Twenty out of ninety-five (21%) patients discontinued 6-TG (mean dose 24.6 mg; mean 6-TGN level 540 pmol/8×108 RBC) within 1 year. Reasons for discontinuation were GI complaints (31%), malaise (15%)and hepatotoxicity (15%). Hematological events occurred in three patients, one discontinued treatment. In the 6-TG-tolerant group, 9% (7/75) could be classified as hepatotoxicity. An abdominal ultrasound was performed in 54% of patients, one patient had splenomegaly.CONCLUSION: The majority of AZA or 6-MP-intolerant IBD patients (79%) is able to tolerate maintenance treatment with 6-TG (dosages between 0.3 and 0.4 mg/kg per d). 6-TG may still be considered as an escape maintenance immunosuppressant in this difficult to treat group of patients, taking into account potential toxicity and efficacy of other alternatives. The recently reported hepatotoxicity is worrisome and 6-TG should therefore be administered only in prospective trials.Nanne KH de Boer Luc JJ Derijks Lennard PL Gilissen Daniel W Hommes Leopold GJB Engels Sybrand Y de Boer Gijsbertus den Hartog Piet M Hooymans Anja BU M(?)kelburg Barend D Westerveld Anton HJ Naber Chris JJ Mulder Dirk J de Jong 2005World Journal of Gastroenterology2005,11,35:4

14全球药物滥用的疾病负担:来自2010年全球疾病负担研究显示文摘背景:直到目前还没有研究者系统地估计过全球及区域性的苯丙胺类、大麻、可卡因和阿片类药物依赖的患病率及其造成的疾病负担。我们旨在用伤残损失寿命年(YLDs)、过早死亡损失寿命年(YLLs)和伤残调整寿命年(DALYs)来估计药物依赖的患病率和其造成的疾病负担。方法:采用贝叶斯Meta回归的方法(Dis Mod-MR)对药物依赖的流行病学研究及2010年全球疾病、伤害及危险因素负担研究(GBD 2010)进行了系统综述,估计人群水平的药物依赖患病率。GBD 2010通过代表性社区调查和基于互联网的调查计算出新的失能权重。我们把估计的药物依赖患病率和新的失能权重结合起来估算药物依赖导致的YLDs、YLLs、DALYs和其作为相关疾病危险因素时导致的YLDs、YLLs和DALYs。结果:2010年,药物依赖直接造成了2千万的DALYs(95%UI(不确定区间)1.3-2.54千万),占全球全因DALYs的0.8%(0.6%-1.0%)。世界范围内,相比于其他药物,越来越多的人依赖于阿片类和苯丙胺类药物。阿片类药物依赖直接造成的疾病负担最大(DALYs为920万,95%UI为710-1140万)。在某些地区,药物依赖导致的DALYs所占比例比其他地区高出20倍,收入越高的国家药物依赖造成的负担所占比例也越高。注射吸毒所致HIV感染造成210万的DALYs(95%UI 110-360万),所致HCV感染导致50.2万的DALYs(95%UI 28.6-89.1万)。苯丙胺类药物依赖所致自杀造成85.4万的DALYs(95%UI 29.1-179.1万),阿片类药物依赖所致自杀造成67.1万的DALYs(95%UI 32.9-173.0万),可卡因依赖所致自杀造成32.4万的DALYs(95%UI 10.9-68.2万)。药物依赖导致的疾病负担最高的国家(>650 DALYs/10万人)包括美国,英国,俄罗斯和澳大利亚。结论:药物滥用是造成全球疾病负担的一个重要因素。为减少人群水平的疾病负担,我们需采取有效的措施(比如给予阿片类药物依赖者替代治疗及针具交换等)降低阿片类药物依赖和注射吸毒导致的疾病负担。王同瑜 Degenhardt L Whiteford HA Ferrari AJ Baxter AJ Charlson FJ Hall WD Freedman G Burstein R Johns Engell RE Flaxman A Murray CJ Vos T 2015中国药物依赖性杂志2015,24,6:3
15Characterization of the Expression of the ATP-Gated P2X7 Receptor Following Status Epilepticus and during Epilepsy Using a P2X7-EGFP Reporter Mouse显示文摘Mounting evidence suggests that the ATP-gated P2X7 receptor contributes to increased hyperexcitability in the brain.While increased expression of P2X7 in the hippocampus and cortex following status epilepticus and during epilepsy has been repeatedly demonstrated,the cell type-specific expression of P2X7 and its expression in extra-hippocampal brain structures remains incompletely explored.In this study,P2X7 expression was visualized by using a transgenic mouse model overexpressing P2X7 fused to the fluorescent protein EGFP.The results showed increased P2X7-EGFP expression after status epilepticus induced by intra-amygdala kainic acid and during epilepsy in different brain regions including the hippocampus,cortex,striatum,thalamus and cerebellum,and this was most evident in microglia and oligodendrocytes.Colocalization of P2X7-EGFP with cell type-specific markers was not detected in neurons or astrocytes.These data suggest that P2X7 activation is a common pathological hallmark across different brain structures,possibly contributing to brain inflammation and neurodegeneration following acute seizures and during epilepsy.James Morgan Mariana Alves Giorgia Conte Aida Menendez-Mendez Laura de Diego-Garcia Gioacchino de Leo Edward Beamer Jonathon Smith Annette Nicke Tobias Engel 2020Neuroscience Bulletin2020,36,11:3
16The cross-cutting contribution of the end of neglected tropical diseases to the sustainable development goals显示文摘The Sustainable Development Goals(SDGs)call for an integrated response,the kind that has defined Neglected Tropical Diseases(NTDs)efforts in the past decade.NTD interventions have the greatest relevance for SDG3,the health goal,where the focus on equity,and its commitment to reaching people in need of health services,wherever they may live and whatever their circumstances,is fundamentally aligned with the target of Universal Health Coverage.NTD interventions,however,also affect and are affected by many of the other development areas covered under the 2030 Agenda.Strategies such as mass drug administration or the programmatic integration of NTD and WASH activities(SDG6)are driven by effective global partnerships(SDG17).Intervention against the NTDs can also have an impact on poverty(SDG1)and hunger(SDG2),can improve education(SDG4),work and economic growth(SDG8),thereby reducing inequalities(SDG10).The community-led distribution of donated medicines to more than 1 billion people reinforces women’s empowerment(SDG5),logistics infrastructure(SDG9)and non-discrimination against disability(SDG16).Interventions to curb mosquito-borne NTDs contribute to the goals of urban sustainability(SDG11)and resilience to climate change(SDG13),while the safe use of insecticides supports the goal of sustainable ecosystems(SDG15).Although indirectly,interventions to control waterand animal-related NTDs can facilitate the goals of small-scale fishing(SDG14)and sustainable hydroelectricity and biofuels(SDG7).NTDs proliferate in less developed areas in countries across the income spectrum,areas where large numbers of people have little or no access to adequate health care,clean water,sanitation,housing,education,transport and information.This scoping review assesses how in this context,ending the epidemic of the NTDs can impact and improve our prospects of attaining the SDGs.Mathieu Bangert David H.Molyneux Steve W.Lindsay Christopher Fitzpatrick Dirk Engels 2017Infectious Diseases of Poverty2017,6,1:3
