2Nonalcoholic fatty liver disease: An overview of current insights in pathogenesis, diagnosis and treatment显示文摘Estimates of people suffering from overweight (one billion) and obesity (300 million) are increasing. The accumulation of triglycerides in the liver, in the absence of excess alcohol intake, has been described in the early sixties. It was not until 1980, however, that Ludwig et al named this condition nonalcoholic steatohepatitis (NASH). Subsequently, nonalcoholic fatty liver disease (NAFLD) has been used as a general name for conditions ranging from simple steatosis through steatohepatitis to end-stage liver disease (cirrhosis). Many studies have demonstrated the significant correlation with obesity and insulin resistance. Other studies have revealed a signifi- cant correlation between hepatic steatosis, cardiovascu- lar disease and increased intima-media thickness. WHO estimated that at least two million patients will develop cirrhosis due to hepatic steatosis in the years to come. Longitudinal cohort studies have demonstrated that those patients with cirrhosis have a similar risk to devel- op hepatocellular carcinoma as those with other causes of cirrhosis. Taken all together, NAFLD has become the third most important indication for liver transplantation. There- fore, training programmes in internal medicine, gastroen- terology and hepatology should stress the importance of diagnosing this entity and treat properly those at risk for developing complications of portal hypertension and con- comittant cardiovascular disease. This review will focus on the clinical characteristics, pathophysiology, imaging tech- niques and the readily available therapeutic options.Tim CMA Schreuder Bart J Verwer Carin MJ van Nieuwkerk Chris JJ Mulder 2008World Journal of Gastroenterology2008,14,16:35
3Challenges in diagnosing mesenteric ischemia显示文摘Early identification of acute mesenteric ischemia (AMI) is challenging. The wide variability in clinical presentation challenges providers to make an early accurate diagnosis. Despite major diagnostic and treatment advances over the past decades, mortality remains high. Arterial embolus and superior mesenteric artery thrombosis are common causes of AMI. Non-occlusive causes are less common, but vasculitis may be important, especially in younger people. Because of the unclear clinical presentation and non-specific laboratory findings, low clinical suspicion may lead to loss of valuable time. During this diagnostic delay, progression of ischemia to transmural bowel infarction with peritonitis and septicemia may further worsen patient outcomes. Several diagnostic modalities are used to assess possible AMI. Multi-detector row computed tomographic angiography is the current gold standard. Although computed tomographic angiography leads to an accurate diagnosis in many cases, early detection is a persistent problem. Because early diagnosis is vital to commence treatment, new diagnostic strategies are needed. A non-invasive simple biochemical test would be ideal to increase clinical suspicion of AMI and would improve patient selection for radiographic evaluation. Thus, AMI could be diagnosed earlier with follow-up computed tomographic angiography or high spatial magnetic resonance imaging. Experimental in vitro and in vivo studies show promise for alpha glutathione S transferase and intestinal fatty acid binding protein as markers for AMI. Future research must confirm the clinical utility of these biochemical markers in the diagnosis of mesenteric ischemia.Teun C van den Heijkant Bart AC Aerts Joep A Teijink Wim A Buurman Misha DP Luyer 2013World Journal of Gastroenterology2013,19,9:31
4Phosphate removal from wastewater by model-La(Ⅲ)zeolite adsorbents显示文摘Phosphorus is one of the primary nutrients which leads to eutrophication and accelerates aging process in enclosed water bodies. Because of the poor phosphorus selectivity of other adsorbents, the novel La(III)-modified zeolite adsorbent (LZA) was prepared by modifying 90 nm zeolite with lanthanide to selectively remove phosphate in the presence of various omnipresent anions, such as sulfates, bicarbonates, and chlorides. Through batch and fixed bed operation, the following optimum conditions were obtained: concentration of lanthanum chloride solution 0.05 mol/L; solid/liquor ratio 1/25; pH 10; calcination temperature 550°C; time 1 h. The value of the Freundlich model constants Kf and 1/n were found to be 16.76 mg/L and 0.2209, respectively. In addition, when calculated at pH 6.0, distribution coefficient KD could be as high as 36.6. Furthermore, in the alkaline pH range, solution of 0.8 mol/L NaCl was used to regenerate the saturated LZA, which could reach the high regeneration efficiency as high as 100%. Because of the good selectivity and regenerability of LZA, it might serve as a potential way for advanced phosphate removal from the sewage containing other anions.NING Ping BART Hans-Jorg LI Bing LU Xiwu ZHANG Yong 2008Journal of Environmental Sciences2008,20,6:30

7Diagnostic and prognostic potential of tissue and circulating long non-coding RNAs in colorectal tumors显示文摘Long non-coding RNAs(lncRNAs)are members of the non-protein coding RNA family longer than 200 nucleotides.They participate in the regulation of gene and protein expression influencing apoptosis,cell proliferation and immune responses,thereby playing a critical role in the development and progression of various cancers,including colorectal cancer(CRC).As CRC is one of the most frequently diagnosed malignancies worldwide with high mortality,its screening and early detection are crucial,so the identification of disease-specific biomarkers is necessary.LncRNAs are promising candidates as they are involved in carcinogenesis,and certain lncRNAs(e.g.,CCAT1,CRNDE,CRCAL1-4)show altered expression in adenomas,making them potential early diagnostic markers.In addition to being useful as tissue-specific markers,analysis of circulating lncRNAs(e.g.,CCAT1,CCAT2,BLACAT1,CRNDE,NEAT1,UCA1)in peripheral blood offers the possibility to establish minimally invasive,liquid biopsy-based diagnostic tests.This review article aims to describe the origin,structure,and functions of lncRNAs and to discuss their contribution to CRC development.Moreover,our purpose is to summarise lncRNAs showing altered expression levels during tumor formation in both colon tissue and plasma/serum samples and to demonstrate their clinical implications as diagnostic or prognostic biomarkers for CRC.Orsolya Galamb Barbara K Barták Alexandra Kalmár Zsófia B Nagy Krisztina A Szigeti Zsolt Tulassay Peter Igaz Béla Molnár 2019World Journal of Gastroenterology2019,25,34:18

10A Comprehensive Overview of Skeletal Phenotypes Associated with Alterations in Wnt/β-catenin Signaling in Humans and Mice显示文摘The Wnt signaling pathway plays key roles in differentiation and development and alterations in this signaling pathway are causally associated with numerous human diseases.While several laboratories were examining roles for Wnt signaling in skeletal development during the 1990s,interest in the pathway rose exponentially when three key papers were published in 2001-2002.One report found that loss of the Wnt co-receptor,Low-density lipoprotein related protein-5(LRP5),was the underlying genetic cause of the syndrome Osteoporosis pseudoglioma(OPPG).OPPG is characterized by early-onset osteoporosis causing increased susceptibility to debilitating fractures.Shortly thereafter,two groups reported that individuals carrying a specific point mutation in LRP5(G171V)develop high-bone mass.Subsequent to this,the causative mechanisms for these observations heightened the need to understand the mechanisms by which Wnt signaling controlled bone development and homeostasis and encouraged significant investment from biotechnology and pharmaceutical companies to develop methods to activate Wnt signaling to increase bone mass to treat osteoporosis and other bone disease.In this review,we will briefly summarize the cellular mechanisms underlying Wnt signaling and discuss the observations related to OPPG and the high-bone mass disorders that heightened the appreciation of the role of Wnt signaling in normal bone development and homeostasis.We will then present a comprehensive overview of the core components of the pathway with an emphasis on the phenotypes associated with mice carrying genetically engineered mutations in these genes and clinical observations that further link alterations in the pathway to changes in human bone.Kevin A.Maupin Casey J.Droscha Bart O.Williams 2013Bone Research2013,1,1:18

12世界腹腔间隙学会腹内高压和腹腔间隙综合征2013版专家共识与诊疗指南显示文摘随着人们对腹内压(intra-abdominal pressure,IAP)的重视,大量研究开始关注腹内高压(intraabdominal hypertension,IAH)和腹腔间隙综合征(abdominal compartment syndrome,ACS).世界腹腔间隙学会(The abdominal compartment society,WSACS)先后在2006年提出了IAH和ACS的专家共识,2007年发表了诊疗指南,2009年明确了疾病相关研究的推荐方向.2013年WSACS发布了新的IAH和ACS专家共识与诊疗指南.该指南由多学科专家共同参与制定,大部分是外科专家和重症监护专家.专家们首先明确24个临床医师关心的IAH和ACS问题,随后进行了系统有序的文献整理.Andrew W.Kirkpatrick Derek J.Roberts Jan De Waele Roman Jaeschke Manu L.N.G.Malbrain Bart De Keulenaer Juan Duchesne Martin Bjorc Ari Leppaniemi 2015中华外科杂志2015,53,3:15
13Boceprevir,GC-376,and calpain inhibitors Ⅱ,Ⅻ inhibit SARS-CoV-2 viral replication by targeting the viral main protease显示文摘A new coronavirus SARS-CoV-2,also called novel coronavirus 2019(2019-nCoV),started to circulate among humans around December 2019,and it is now widespread as a global pandemic.The disease caused by SARS-CoV-2 virus is called COVID-19,which is highly contagious and has an overall mortality rate of 6.35%as of May 26,2020.There is no vaccine or antiviral available for SARS-CoV-2.In this study,we report our discovery of inhibitors targeting the SARS-CoV-2 main protease(Mpro).Using the FRET-based enzymatic assay,several inhibitors including boceprevir,GC-376,and calpain inhibitorsⅡ,andⅫwere identified to have potent activity with single-digit to submicromolar ICs0 values in the enzymatic assay.The mechanism of action of the hits was further characterized using enzyme kinetic studies,thermal shift binding assays,and native mass spectrometry.Significantly,four compounds(boceprevir,GC-376,calpain inhibitorsⅡandⅫ)inhibit SARS-CoV-2 viral replication in cell culture with EC50 values ranging from 0.49 to 3.37μM.Notably,boceprevir,calpain inhibitorsⅡandⅫrepresent novel chemotypes that are distinct from known substrate-based peptidomimetic Mpro inhibitors.A complex crystal structure of SARS-CoV-2 Mpro with GC-376,determined at 2.15(A)resolution with three protomers per asymmetric unit,revealed two unique binding configurations,shedding light on the molecular interactions and protein conformational flexibility underlying substrate and inhibitor binding by Mpro.Overall,the compounds identified herein provide promising starting points for the further development of SARS-CoV-2 therapeutics.Chunlong Ma Michael Dominic Sacco Brett Hurst Julia Alma Townsend Yanmei Hu Tommy Szeto Xiujun Zhang Bart Tarbet Michael Thomas Marty Yu Chen Jun Wang 2020Cell Research2020,30,8:13
14SARS-CoV-2 Omicron variant is highly sensitive to molnupiravir,nirmatrelvir,and the combination显示文摘Dear Editor,Since the first outbreak in late 2019,the RNA genome of SARS-CoV-2 has been undergoing constant evolution.This is largely attributed to the viral polymerase that is intrinsically error prone and the selection pressures exerted by the host immune system.Several variants of concern harboring multiple mutations in the spike protein have emerged in the past year.The currently fast-spreading Omicron variant contains many more mutations compared with the previous variants,and most of these mutations are located around the receptor binding domain of the spike protein.Pengfei Li Yining Wang Marla Lavrijsen Mart M.Lamers Annemarie C.de Vries Robbert J.Rottier Marco J.Bruno Maikel P.Peppelenbosch Bart L.Haagmans Qiuwei Pan 2022Cell Research2022,32,3:11
15Haplotype of prostaglandin synthase 2/cyclooxygenase 2 is involved in the susceptibility to inflammatory bowel disease显示文摘AIM: Prostaglandin G/H synthase 2 (PTGS2 or COX2) is one of the key factors in the cellular response to inflammation.PTGS2 is expressed in the affected intestinal segments of patients with inflammatory bowel diseases (IBD). In IBD patients, non-steroidal anti-inflammatory drugs, which have been shown to reduce both the production and activity of PTGS2, may activate IBD and aggravate the symptoms.We aimed at examining genetic variants of PTGS2 that may be risk factors for IBD.METHODS: We genotyped 291 individuals diagnosed with IBD and 367 controls from the Dutch population for the five most frequent polymorphisms of the PTGS2 gene.Clinical data were collected on all patients. DNA was extracted via normal laboratory methods. Genotyping was carried out using multiplex PCR followed by the Invader Assay and the 5' exonuclease assay (TaqMan). New polymorphism screening was performed by pre-screening with denaturing high-performance liquid chromatography,followed by fluorescent sequencing.RESULTS: Allele 5209G was weakly associated with Crohn's disease (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.03-2.57), and allele 8473T with ulcerative colitis (OR 1.50, 95%CI 1.00-2.27). The haplotype including both alleles showed a strong association with IBD (OR 13.15, 95%CI 3.17-116.15). This haplotype, while rare (-0.3%) in the general population, is found more frequently in patients (3.5%).CONCLUSION: Our data suggest that this haplotype of PTGS2 contributes to the susceptibility of IBD.David G Cox J Bart A Crusius Petra HM Peeters H Bas Bueno-de-Mesquita A Salvador Pe(n|~)a Federico Canzian 2005World Journal of Gastroenterology2005,11,38:10
16社会文化制度对门禁社区发展的影响——中国和荷兰的对比研究显示文摘作为后现代城市主义的典型空间形态,门禁社区在全球的蔓延引起了学界的广泛关注。当前对门禁社区发展机制的探讨主要集中于全球性宏观社会环境和消费者需求的层面,但对供给方的推动和制约因素关注不够。本文从制度视角出发,以中国和荷兰为案例,分析了门禁社区发展的异同,并具体从住房开发政策过程、历史传统和价值观两方面去理解和解释产生这种差异的原因。研究既是对从供给角度研究门禁社区的补充和拓展,同时也显示了本土制度环境解释人文地理学问题的必要性和重要性。指出在借鉴西方理论理解中国城市空间结构和社会变迁问题的同时,也不可忽视中国自身历史文化因素和社会制度背景。封丹 Bart Wissink Werner Breitung 2010世界地理研究2010,19,4:10
17喷水推进混流泵叶片径向力显示文摘水力机械内的水压力脉动常常导致叶片的疲劳破坏及共振,为了研究叶片旋转交互作用引起的流体诱导水压力,基于CFD计算和模型试验开展导叶式喷水推进混流泵叶片交互作用径向力研究.建立了一个闭式的混流泵试验循环系统,在叶轮和泵轴内内置同步旋转测力计测量叶轮上的瞬时力和转矩.通过大量的标定确定试验轴系的动态特性.采用Fluent软件进行非定常数值模拟,并将模拟结果与试验结果进行了比较,分析了产生偏差的原因.结果表明:叶片旋转经过时的轴上径向作用力的频率与工况有关,同时叶片激发的径向力导致叶轮有与轴旋转方向相反旋转的趋势;计算的推进泵外特性与试验吻合较好,同时叶片交互作用径向力的量级也有较好的吻合度;从小流量到大流量工况,计算结果的变化趋势与试验结果一致.成立 Bart P.M.van Esch 刘超 周济人 金燕 2012排灌机械工程学报2012,30,6:9
18Acute necrotizing pancreatitis as fi rst manifestation of primary hyperparathyroidism显示文摘We report the case of a female patient with severe acute necrotizing pancreatitis associated with hypercalcemia as first manifestation of primary hyperparathyroidism caused by a benign parathyroid adenoma.Initially the acute pancreatitis was treated conservatively.The patient subsequently underwent surgical resection of the parathyroid adenoma and surgical clearance of a large infected pancreatic pseudocyst.Although the association of parathyroid adenoma-induced hypercalcemia and acute pancreatitis is a known medical entity,it is very uncommon.The pathophysiology of hypercalcemia-induced acute pancreatitis is therefore not well known,although some mechanisms have been proposed.It is important to treat the provoking factor.Therefore,the cause of hypercalcemia should be identif ied early.Surgical resection of the parathyroid adenoma is the ultimate therapy.Jeroen I Lenz Jimmy M Jacobs Bart Op de Beeck Ivan A Huyghe Paul A Pelckmans Tom G Moreels 2010World Journal of Gastroenterology2010,16,23:9
19原水性质对纳滤去除三嗪类除草剂的影响显示文摘为考察原水性质(water matrix)对纳滤去除三嗪类除草剂的影响,以某市河水及管网水配制的5mg/L 的农药溶液为对象,研究了4种纳滤膜(DESAL51 HL、UTC-20、UTC 60)对其中阿特拉津和西玛津的截留率及水通量的变化.结果表明,相对于蒸馏水而言,河水及管网水能提高纳滤对农药的截留率,并降低水通量.对于河水和管网水引起相似的截留率提高和水通量减少,其机制设想为由于离子在膜表面或孔径内的吸附,导致了膜有效孔径的堵塞或变小,从而使更多的除草剂分子在通过膜的过程中被截留.河水和管网水中天然有机物的存在对纳滤膜截留有机物能力的影响较小.在选用的4种膜中,UTC-20不受原水水质的影响,对COD、硝酸盐等污染物有较高的去除率并保持较高的水通量.张阳 张颖 陈冠雄 VAN DER BRUGGEN Bart VANDECASTEELE Carlo 2005哈尔滨工业大学学报2005,37,3:8
20颈部动脉夹层分离及其与颈椎推拿疗法的联系: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目的:颈部动脉夹层分离(cervicalarterydissection,CD)是中青年人卒中的最常见病因。本指南旨在对CD诊治的现有证据水平以及其与颈椎推拿疗法(cervical manipulative therapy, CMT)的统计学联系进行回顾。某些类型的CMT是由医疗专业人员对颈椎施加猛烈或轻柔的推力。方法写作组成员由美国心脏协会卒中委员会的科学声明监督委员会以及美国心脏协会的手稿监督委员会任命。各成员负责与其专业领域相关的主题,回顾适当的文献并参考公开发表的临床和流行病学研究、发病率和死亡率报告、临床与公共卫生指南、权威声明、个人文件以及专家意见,对现有证据进行总结并指出目前的知识空白。结果CD患者可表现为单侧头痛、后颈部痛或主要由动脉-动脉栓塞导致的脑或视网膜缺血(短暂性缺血或卒中)、CD脑神经麻痹、眼交感神经麻痹或搏动性耳鸣。CD的诊断依赖于完整的病史、体格检查和针对性的辅助检查。尽管轻微创伤的作用存在争议,但机械压力可造成椎动脉和颈内动脉内膜损伤,进而导致CD。CD患者的残疾程度存在差异,一些患者预后良好,但有些患者则会出现严重神经系统后遗症。目前尚无循证指南可用来指导CD的最佳处理策略。抗血小板和抗凝治疗均被用于局部血栓和继发性栓塞的预防。病例对照研究和其他文献提示CD[尤其是椎动脉夹层分离(vertebral artery dissection, VAD)]与CMT之间存在流行病学联系,但尚不清楚这是由于对先前存在的CD认识不足还是CMT导致的创伤。超声、CT血管造影以及磁共振血管造影都有助于CD的诊断。神经影像学随访首选无创性检查措施,但我们认为任何单一的检查方法都不能作为金标准。结论 CD是中青年患者发生缺血性卒中的重要病因。CD最好发于颈椎上段,可累及颈内动脉或椎动脉。尽管目前的生物力学证据不足以证实CMT 可导致CD,但临床报道提示机械压力在相当一部分CD中起着一定的作用,而且大多数基于人群的对照研究在年轻患者中显示CMT与VAD卒中之间存在联系。尽管对于曾经接受过CMT的患者,CMT相关性CD的发生率尚不完全清楚并且很可能较低,但当有临床症状时,医生应考虑到CD的可能性,并且在进行颈椎推拿前告知患者CD与CMT之间的统计学联系。José Biller Ralph L.
