1FXR: a metabolic regulator and cell protector显示文摘Farnesoid X 受体(FXR ) 是激活 ligand 的抄写因素的原子受体总科的一个成员。作为一个新陈代谢的管理者, FXR 戏在胆汁酸,胆固醇,类脂化合物,和葡萄糖新陈代谢给角色调音。因此, FXR 是为很多新陈代谢的混乱的一个潜在的药目标,特别那些与新陈代谢的症候群有关。更最近,我们的组和其它扩大了 FXR 的功能到非常新陈代谢的规定,它在肠,肝新生,和 hepatocarcinogenesis 包括抗菌剂生长。这些新调查结果比以前想建议 FXR 有宽广得多的角色,并且也为多重疾病作为一个药目标加亮 FXR。这评论总结 FXR 的基本信息,但是集中于它的新功能。Yan-Dong Wang Wei-Dong Chen David D Moore Wendong Huang 2008Cell Research2008,18,11:33
2What we should know about portal vein thrombosis in cirrhotic patients:A changing perspective显示文摘Portal vein thrombosis(PVT) is one of the most common complications occurring during the natural course of liver cirrhosis.Even though PVT is often asymptomatic,the worsening of liver function,an unexpected episode of gastrointestinal bleeding or ascitic decompensation may be landmarks of PVT development.Beyond these clinical manifestations,it is debated whether PVT really has an impact on liver cirrhosis natural history or rather represents only one of its consequences.Probably PVT development should not only be considered as a matter of impaired blood flow or pro-coagulation tendency.On one hand,PVT seems a consequence of the worsening in portal vein outflow due to the increased hepatic resistance in cirrhotic livers.On the other hand,vascular microthrombosis secondary to necroinflammation may cause liver ischemia and infarction,with loss of hepatic tissue(parenchymal extinction) which is replaced by fibrotic tissue.Therefore,PVT might also be considered as the overt manifestation of the liver fibrosing process evolution and anticoagulant therapy may thus have microscopic indirect effects also on the progression of liver disease.At present,a connection between PVT development and the progression of liver fibrosis/cirrhosis has not yet been demonstrated.Nevertheless,it is not clear if PVT development may worsen cirrhotic patients' outcome by itself.Some authors tried to assess liver transplant benefit in PVT cirrhotic patients but data are contrasting.In this review,we will try to answer these questions,providing a critical analysis of data reported in literature.Francesca Romana Ponziani Maria Assunta Zocco Matteo Garcovich Francesca D'Aversa Davide Roccarina Antonio Gasbarrini 2012World Journal of Gastroenterology2012,18,36:24

8Diagnostic accuracy of endoscopic ultrasound in pancreatic neuroendocrine tumors: A systematic review and meta analysis显示文摘AIM: To detect pancreatic neuroendocrine tumors (PNETs) has been varied. This study is undertaken to evaluate the accuracy of endoscopic ultrasound (EUS) in detecting PNETs.METHODS: Only EUS studies confirmed by surgery or appropriate follow-up were selected. Articles were searched in Medline, Ovid journals, Medline nonindexed citations, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. Pooling was conducted by both fixed and random effects model). RESULTS: Initial search identified 2610 reference articles, of these 140 relevant articles were selected and reviewed. Data was extracted from 13 studies (n = 456) which met the inclusion criteria. Pooled sensitivity of EUS in detecting a PNETs was 87.2% (95%CI: 82.2-91.2). EUS had a pooled specificity of 98.0% (95%CI: 94.3-99.6). The positive likelihood ratio of EUS was 11.1 (95%CI: 5.34-22.8) and negative likelihood ratio was 0.17 (95%CI: 0.13-0.24). The diagnostic odds ratio, the odds of having anatomic PNETs in positive as compared to negative EUS studies was 94.7 (95%CI: 37.9-236.1). Begg-Mazumdar bias indicator for publication bias gave a Kendall's tau value of 0.31 (P = 0.16), indication no publication bias. The P for χ2 heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION: EUS has excellent sensitivity and specificity to detect PNETs. EUS should be strongly considered for evaluation of PNETs.Srinivas R Puli Nikhil Kalva Matthew L Bechtold Smitha R Pamulaparthy Micheal D Cashman Norman C Estes Richard H Pearl Fritz-Henry Volmar Sonu Dillon Michael F Shekleton David Forcione 2013World Journal of Gastroenterology2013,19,23:14

10Efficacy of adjuvant XELOX and FOLFOX6 chemotherapy after D2 dissection for gastric cancer显示文摘AIM: To compare the efficacy of capecitabine and oxaliplatin (XELOX) with 5-fluorouracil, folinic acid and oxaliplatin (FOLFOX6) in gastric cancer patients after D2 dissection. METHODS: Between May 2004 and June 2010, patients in our gastric cancer database who underwent D2 dissection for gastric cancer at the First Affiliated Hospital of Sun Yat-Sen University were retrospectively analyzed. A total of 896 patients were enrolled into this study according to the established inclusion and exclusion criteria. Of these patients, 214 received the XELOX regimen, 48 received FOLFOX6 therapy and 634 patients underwent surgery only without chemotherapy. Overall survival was compared among the three groups using Cox regression and propensity score matchedpair analyses. RESULTS: Patients in the XELOX and FOLFOX6 groups were younger at the time of treatment (median age 55.2 years; 51.2 years vs 58.9 years), had more undifferentiated tumors (70.1%; 70.8% vs 61.4%), and more lymph node metastases (80.8%; 83.3% vs 57.7%), respectively. Overall 5-year survival was 57.3% in the XELOX group which was higher than that (47.5%) in the surgery only group (P = 0.062) and that (34.5%) in the FOLFOX6 group (P = 0.022). Multivariate analysis showed that XELOX therapy was an independent prognostic factor (hazard ratio = 0.564, P < 0.001). After propensity score adjustment, XELOX significantly increased overall 5-year survival compared to surgery only (58.2% vs 44.2%, P = 0.025) but not compared to FOLFOX6 therapy (48.5% vs 42.7%, P = 0.685). The incidence of grade 3/4 adverse reactions was similar between the XELOX and FOLFOX6 groups, and more patients suffered from hand-foot syndrome in the XELOX group (P = 0.018). CONCLUSION: Adjuvant XELOX therapy is associated with better survival in patients after D2 dissection, but does not result in a greater survival benefit compared with FOLFOX6 therapy.Ying Wu Zhe-Wei Wei Yu-Long He Roderich E Schwarz David D Smith Guang-Kai Xia Chang-Hua Zhang 2013World Journal of Gastroenterology2013,19,21:14

12Global Wheat Head Detection(GWHD)Dataset:A Large and Diverse Dataset of High-Resolution RGB-Labelled Images to Develop and Benchmark Wheat Head Detection Methods显示文摘The detection of wheat heads in plant images is an important task for estimating pertinent wheat traits including head population density and head characteristics such as health,size,maturity stage,and the presence of awns.Several studies have developed methods for wheat head detection from high-resolution RGB imagery based on machine learning algorithms.However,these methods have generally been calibrated and validated on limited datasets.High variability in observational conditions,genotypic differences,development stages,and head orientation makes wheat head detection a challenge for computer vision.Further,possible blurring due to motion or wind and overlap between heads for dense populations make this task even more complex.Through a joint international collaborative effort,we have built a large,diverse,and well-labelled dataset of wheat images,called the Global Wheat Head Detection(GWHD)dataset.It contains 4700 high-resolution RGB images and 190000 labelled wheat heads collected from several countries around the world at different growth stages with a wide range of genotypes.Guidelines for image acquisition,associating minimum metadata to respect FAIR principles,and consistent head labelling methods are proposed when developing new head detection datasets.The GWHD dataset is publicly available at http://gffzzef49fa24bca249bbh556n6p95fq5o6o0k.ffgz.tsg.suse.edu.cn/and aimed at developing and benchmarking methods for wheat head detection.Etienne David Simon Madec Pouria Sadeghi-Tehran Helge Aasen Bangyou Zheng Shouyang Liu Norbert Kirchgessner Goro Ishikawa Koichi Nagasawa Minhajul A.Badhon Curtis Pozniak Benoit de Solan Andreas Hund Scott C.Chapman Frédéric Baret Ian Stavness Wei Guo 2020Plant Phenomics2020,2,1:13

14将卒中纳入心血管风险预测工具美国心脏协会/美国卒中协会对医疗卫生专业人员的声明显示文摘背景和目的目前美国针对心血管事件风险预测以及一级和二级预防的指南声明均使用绝对风险估计值来识别血管事件高危患者以及可从特定干预措施中获益的患者。然而,这些指南并未明确地包括卒中患者。本指南对现有证据和争论进行概述以支持:(1)将卒中(尤其是动脉粥样硬化性卒中)患者纳入心血管病绝对风险增高的患者群体;(2)将卒中纳入血管性疾病风险预测工具的转归预测因素。方法和结果写作组成员由委员会联合主席基于先前在相关领域的研究成果来提名,并得到美国心脏协会(American Heart Association,AHA)卒中委员会科学声明监督委员会以及文稿监督委员会的批准。作者采用系统文献回顾(覆盖1980年1月至2010年3月期间的文献)并参考以往公布的指南、个人资料以及专家观点,以归纳现有证据,提出当前知识的不足,并根据AHA标准对适当的问题制定推荐意见。所有写作组成员均有机会对推荐意见进行评论并批准了最终版本。经广泛的AHA内部同行评议以及卒中委员会领导阶层和科学声明监督委员会的审阅后,最终获得AHA科学咨询和协调委员会的批准。将卒中患者(尤其是动脉粥样硬化性卒中患者)纳入冠状动脉和心血管病绝对高危人群的原因如下。首先,有证据显示,缺血性卒中患者发生致死性和非致死性心肌梗死或猝死的绝对风险增高,10年绝对风险≥20%,这一风险阈值已被一些指南用于定义冠状动脉疾病风险等危症。其次,纳入动脉粥样硬化性卒中的原因与纳入糖尿病、周围血管病、慢性肾脏病以及其他动脉粥样硬化性疾病的原因相同,尽管尚缺乏在所有人群或患者中风险增高的统一证据。再次,缺血性卒中的大动脉粥样硬化性卒中亚型与其他这些疾病的病理生理学机制相同。将卒中纳入高危因素将导致高危人群的数量扩大约10%。然而,由于卒中的异质性,尚不确定其他卒中亚型,包括出血性卒中以及非动脉粥样硬化性卒中亚型,是否应被视为具有相同水平的风险,因此有待进一步研究。鉴于卒中对残疾和死亡的影响、卒中与其他血管性疾病预防措施的相似性以及卒中在某些人群中较冠状动脉疾病更高的重要性,将卒中、心肌梗死和猝死纳入心血管事件风险预测工具的转归预测因素是合适的。美国以外的指南常常将卒中患者纳入心血管高危人群,并将卒中作为心脏终点的一个相关转归事件。结论动脉粥样硬化性卒中患者应被纳入会进一步发生冠状动脉粥样硬化事件的高危患者(10年≥20%)。是否应纳入非动脉粥样硬化卒中亚型尚不确定。对于一级预防,缺血性卒中应被纳入绝对风险评估方案的心血管疾病转归事件。将动脉粥样硬化性卒中作为一个高危因素或者更宽泛地将缺血性卒中视作一种转归事件纳入,可能对心血管病的预防具有重要意义,因为被评定为高危风险的患者数量将大幅增加。Daniel T.

15Role of blood AFP mRNA and tumor grade in the preoperative prognostic evaluation of patients with hepatoceiluiar carcinoma显示文摘AIM: To explore the potential prognostic role of preoperative tumor grade and blood AFP mRNA in a cohort of patients with hepatocellular carcinoma (HCC)eligible for radical therapies according to a well-defined treatment algorithm not including nodule size and number as absolute selection criteria.METHODS: Fifty patients with a diagnosis of HCC were prospectively enrolled in the study. Inclusion criteria were: (1) histological assessment of tumor grade by means of percutaneous biopsies; (2) determination of AFP mRNA status in the blood; (3) patient's eligibility for radical therapies.RESULTS: At preoperative evaluation, 54% of the study group had a well-differentiated HCC, 42% had AFP mRNA in the blood, 40% had a tumor larger than 5 cm and 56% had more than one nodule. Surgery (resection or liver transplantation) was performed in 29 patients,while 21 had percutaneous ablation procedures. After a median follow-up of 28 mo, 12-, 24-, and 36-mo survival rates were 78%, 58%, and 51%, respectively. Surgical therapy, performance status and three tumor-related variables (AFP mRNA, HCC grade and gross vascular invasion) resulted as significant survival predictors at univariate analysis. Nodule size and number did not perform as significant prognosticators. Multivariate study selected only surgical therapy and a biologically early HCC profile (AFP mRNA negative and well-differentiated tumor without gross vascular invasion) as independent survival variables.CONCLUSION: The preoperative determination of tumor grade and blood AFP mRNA status may potentially refine the prognostic evaluation of HCC patients and improve the selection process for radical therapies.Umberto Cillo Alessandro Vitale Filippo Navaglia Daniela Basso Umberto Montin Marco Bassanello Francesco D'Amico Francesco Antonio Ciarleglio Alberto Brolese Giacomo Zanus Vito De Pascale Mario Plebani Davide Francesco D'Amico 2005World Journal of Gastroenterology2005,11,44:12
16植物甾醇和植物甾烷醇:来源、安全性以及在保健食品中的应用显示文摘包括植物甾醇和植物甾烷醇在内的植物固醇天然存在于植物细胞中,作为构成细胞膜的组成成分。在植物油和松科树木的树油中含有丰富的植物固醇,特别是β-谷甾醇、菜油甾醇和豆甾醇。在动物实验和人体临床实验中发现植物固醇具有降低总胆固醇和LDL胆固醇的作用。临床实验的结果表明,每日摄入1—2g的植物固醇可以达到降低州10%—15%的血清胆固醇的作用。其作用机制与植物固醇同胆固醇的结构类似性及其在乳糜微粒中的溶解度有关,从而降低胆固醇在肠道中的吸收。一般认为植物固醇是安全的,它本身是正常膳食中的一部份。临床毒理学研究发现有效剂量之内的植物固醇不仅能降低胆固醇而且对人和动物没有毒性,虽然有对于食物中的植物固醇影响类胡萝卜素吸收的担心,但从临床研究的结果中证明只要在膳食中增加一份的富含类胡萝卜素的水果和蔬菜就可以轻易解决这一问题。Jerzy Zawistowski 胡春 David D Kitts 2002中国食品学报2002,2,2:12
17More anxious than depressed:prevalence and correlates in a 15-nation study of anxiety disorders in people with type 2 diabetes mellitus显示文摘Background Anxiety disorder, one of the highly disabling, prevalent and common mental disorders, is known to be more prevalent in persons with type 2 diabetes mellitus (T2DM) than the general population, and the comorbid presence of anxiety disorders is known to have an impact on the diabetes outcome and the quality of life. However, the information on the type of anxiety disorder and its prevalence in persons with T2DM is limited. Aims To assess the prevalence and correlates of anxiety disorder in people with type 2 diabetes in different countries. Methods People aged 18-65 years with diabetes and treated in outpatient settings were recruited in 15 countries and underwent a psychiatric interview with the Mini-International Neuropsychiatric Interview. Demographic and medical record data were collected. Results A total of 3170 people with type 2 diabetes (56.2% women;with mean (SD) duration of diabetes 10.01 (7.0) years) participated. The overall prevalence of anxiety disorders in type 2 diabetic persons was 18%;however, 2.8% of the study population had more than one type of anxiety disorder. The most prevalent anxiety disorders were generalised anxiety disorder (8.1%) and panic disorder (5.1%). Female gender, presence of diabetic complications, longer duration of diabetes and poorer glycaemic control (HbA1c levels) were significantly associated with comorbid anxiety disorder. A higher prevalence of anxiety disorders was observed in Ukraine, Saudi Arabia and Argentina with a lower prevalence in Bangladesh and India. Conclusions Our international study shows that people with type 2 diabetes have a high prevalence of anxiety disorders, especially women, those with diabetic complications, those with a longer duration of diabetes and poorer glycaemic control. Early identification and appropriate timely care of psychiatric problems of people with type 2 diabetes is warranted.Santosh K Chaturvedi Shayanth Manche Gowda Helal Uddin Ahmed Fahad D Alosaimi Nicola Andreone Alexey Bobrov Viola Bulgari Giuseppe Carra Gianluca Castelnuovo Giovanni de Girolamo Tomasz Gondek Nikola Jovanovic Thummala Kamala Andrzej Ki Nebojsa Lalic Dusica Lecic-Tosevski Fareed Minhas Victoria Mutiso David Ndetei Golam Rabbani Suntibenchakul Somruk Sathyanarayana Srikanta Rizwan Taj Umberto Valentini Olivera Vukovic Wolfgang Wolwer Larry Cimino Arie Nouwen Cathy Lloyd Norman Sartorius 2019General Psychiatry2019,32,4:11
18Intentional ingestions of foreign objects among prisoners: A review显示文摘The intentional ingestion of foreign objects(IIFO) is described more commonly in prison populations than in the general population, with an estimated annual incidence of 1 in 1900 inmates in our state correctional facilities. Incidents often involve ingestion of small metal objects(e.g., paperclips, razor blades) or other commonly available items like pens or eating utensils. Despite ingestion of relatively sharp objects, most episodes can be clinically managed with either observation or endoscopy. Surgery should be reserved for those with signs or symptoms of gastrointestinal perforation or obstruction. For those with a history of IIFO, efforts should focus on prevention of recurrenceas subsequent episodes are associated with higher morbidity, significant healthcare and security costs. The pattern of IIFO is often repetitive, with escalation both in frequency of ingestions and in number of items ingested. Little is known about successful prevention strategies, but efforts to monitor patients and provide psychiatric care are potential best-practice strategies. This article aims to provide state-of-the art review on the topic, followed by a set of basic recommendations.David C Evans Thomas R Wojda Christian D Jones Andrew J Otey Stanislaw P Stawicki 2015World Journal of Gastrointestinal Endoscopy2015,7,3:10
19英国胃肠病学会关于胃癌风险患者的诊断和管理指南显示文摘胃癌预后较差,部分原因在于诊断较晚。胃癌的危险因素包括幽门螺杆菌(H.pylori,HP)感染和胃癌家族史,尤其是遗传性弥漫性胃癌和恶性贫血。胃癌发展的阶段包括慢性胃炎、胃黏膜萎缩(GA)、胃黏膜肠化生(GIM)和异型增生。胃癌早期发现和提高生存率的关键是在内镜检查前以非侵入性方式识别高危人群。然而,尽管生物标志物可能有助于检测慢性萎缩性胃炎,但尚无足够的证据支持其用于人群筛查。高质量内镜检查是胃癌早期发现的重要组成部分,图像增强内镜结合组织病理学活检是GA和GIM最佳的诊断方法,并能准确进行风险分层。按照悉尼标准从胃窦、角切迹、小弯和大弯进行活检,既能明确诊断,也能对胃癌进行风险分层。理想状态应当是在高质量内镜检查中对GA或GIM区域活检。英国属于低危地区,可根据需要接受常规诊断性胃镜检查,但没有足够证据支持筛查,对于广泛GA或GIM的患者,每3年检查内镜。对于胃异型增生和早期癌,只要满足标准,内镜下黏膜切除术或内镜黏膜下剥离术的治疗有效,成功率高,复发率低。Matthew Banks David Graham Marnix Jansen TakujiGotoda Sergio Coda Massimiliano di Pietro NoriyaUedo Pradeep Bhandari D Mark Pritchard Ernst J Kuipers Manuel Rodriguez-Justo Marco R Novelli KrishRagunath Neil Shepherd Mario Dinis-Ribeiro 乌雅罕(译) 张冬雪(译) 牛占岳(校) 刘鑫(校) 丁士刚(译/校) 2020中华胃肠内镜电子杂志2020,7,2:10
20Two quantitative trait loci, Dw1 and Dw2, are primarily responsible for rootstock-induced dwarfing in apple显示文摘The apple dwarfing rootstock‘Malling9’(‘M9’)has been used worldwide both to reduce scion vigour and as a genetic source for breeding new rootstocks.Progeny of‘M9’segregate for rootstock-induced dwarfing of the scion,indicating that this trait is controlled by one or more genetic factors.A quantitative trait locus(QTL)analysis of a rootstock population derived from the cross between‘M9’בRobusta5’(non-dwarfing)and grafted with‘Braeburn’scions identified a major QTL(Dw1)on linkage group(LG)5,which exhibits a significant influence on dwarfing of the scion.A smaller-effect QTL affecting dwarfing(Dw2)was identified on LG11,and four minor-effect QTLs were found on LG6,LG9,LG10 and LG12.Phenotypic analysis indicates that the combination of Dw1 and Dw2 has the strongest influence on rootstock-induced dwarfing,and that Dw1 has a stronger effect than Dw2.Genetic markers linked to Dw1 and Dw2 were screened over 41 rootstock accessions that confer a range of effects on scion growth.The majority of the dwarfing and semi-dwarfing rootstock accessions screened carried marker alleles linked to Dw1 and Dw2.This suggests that most apple dwarfing rootstocks have been derived from the same genetic source.Toshi M Foster Jean-Marc Celton David Chagné D Stuart Tustin Susan E Gardiner 2015Horticulture Research2015,2,1:10
