| 1 | 淹水土壤有机酸积累与秸秆碳氮比及氮供应的关系显示文摘有机酸积累和毒害是稻田秸秆还田中受到广泛关注的问题。本文以水稻与小麦秸秆为材料,采用淹水培养研究了甲酸、乙酸、丙酸及丁酸在土壤中的积累及其与秸秆碳氮比、氮肥添加量的关系。结果表明,在不施用氮肥的情况下,随秸秆用量的增加,秸秆处理的有机酸积累均显著增多。与稻秸处理相比,麦秸处理的有机酸(尤其是丙酸)积累量显著较高,土壤溶液中NH4+浓度显著较低。加入尿素明显减少有机酸积累,促进CH4排放,但对CO2的排放无显著影响;氮素的影响在麦秸处理中表现的尤为明显。上述结果说明麦秸的高碳氮比增加了无机氮的生物固定,抑制有机酸向CH4转化,从而导致麦秸处理有机酸积累量高于稻秸处理。施用氮肥是减少麦秸还田后有机酸积累的有效措施之一,但此措施将可能促进CH4的排放。 | 单玉华 蔡祖聪 韩勇 Sarah E Johnson Roland J Buresh | 2006 | 土壤学报2006，43，6： | 68 |

| 3 | 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 |
| 4 | 抗菌蜂蜜预防腹膜透析相关感染:一项随机对照试验显示文摘背景 目前缺少指导预防腹膜透析相关感染策略的研究证据。抗菌蜂蜜作为一种新型、廉价、有效的局部预防性使用的药物,不会诱导细菌耐药。因此,我们评估,对鼻内定植金黄色葡萄球菌的患者,与同时进行腹膜管外出口部位常规护理加上鼻内莫匹罗星去定植的方法相比,腹膜管外出口部位每日使用蜂蜜,是否会延迟首次出现腹膜透析相关感染的时间。 | Johnson D W Badve S V Pascoe E M 陈玉华 | 2014 | 中国感染控制杂志2014，13，2： | 7 |
| 5 | Artificial 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 | 2021 | World Journal of Gastroenterology2021，27，40： | 6 |
| 6 | Radial artery access site complications during cardiac procedures,clinical implications and potential solutions: The role of nitric oxide显示文摘Percutaneous coronary intervention for the treatment of coronary artery disease is most commonly performed in the UK through the radial artery,as this is considered to be safer than the femoral approach.However,despite improvements in technology and techniques,complications can occur.The most common complication,arterial spasm,can cause intense pain and,in some cases,procedural failure.The incidence of spasm is dependent on several variables,including operator experience,artery size,and equipment used.An antispasmolytic cocktail can be applied to reduce spasm,which usually includes an exogenous nitric oxide(NO)donor(glyceryl trinitrate).NO is an endogenous local vasodilator and therefore is a potential target for anti-spasm intervention.However,systemic administration can result in unwanted side-effects,such as hypotension.A method that adopts local delivery of NO might be advantageous.This review article describes the mechanisms involved in radial artery spasm,discusses the advantages and disadvantages of current strategies to reduce spasm,and highlight the potential of NO-loaded nanoporous materials for use in this setting. | Emma M Coghill Timothy Johnson Russell E Morris Ian L Megson Stephen J Leslie | 2020 | World Journal of Cardiology2020，12，1： | 4 |
| 7 | Primary mucosa-associated lymphoid tissue lymphoma of the liver: A report of two cases and review of the literature显示文摘Mucosa-associated lymphoid tissue(MALT) lymphoma of the liver is a very rare condition and thus the diag-nosis may be challeng-ing-. The clinical presentation is usually variable, rang-ing- from minimal clinical symptoms to severe end stag-e liver disease. In this paper, we describe the clinicopatholog-ic finding-s in two cases of primary hepatic MALT lymphoma. One case is an 80-year-old female with no underlying- chronic liver disease and the second case is a 30-year-old female with autoimmune hepatitis complicated by MALT lymphoma. In both specimens, there was diffuse infiltration of atypical B-lymphocytes that were positive for CD20 and CD79 a, but neg-ative for CD5, CD43 and CD10. There were occasional lymphoepithelial lesions involving- the hepatocytes or bile ducts. Polymerase chain reaction analysis showed monoclonal immunog-lobulin heavy chain g-ene rearrang-ement in both cases. The first case was treated with surg-ery but developed pulmonary recurrence a year after complete resection but went into remission following- treatment with rituximab. A second recurrence occurred in the rig-ht parotid g-land 7 years later, which was treated with idelalisib. The second case was effectively treated with rituximab. To our knowledg-e, the second case is the first reported case linked to autoimmune hepatitis. | Ifeyinwa E Obiorah Lynt Johnson Metin Ozdemirli | 2017 | World Journal of Hepatology2017，9，3： | 4 |

| 9 | 儿科CT应用和辐射暴露与癌症预测风险联系的研究显示文摘背景和目的计算机断层扫描(CT)在儿科的使用增加了人们对电离辐射暴露导致癌症风险的关注。本回顾性研究的目的在于量化确定在儿科使用CT和相关辐射暴露与癌症风险联系的趋势。方法调查自1996年至2010年间15岁以下接受过CT检查的儿童,共4,857,736人年。对五家保健系统于2001年至2011年间进行的744起对头部、腹部/骨盆、胸部和脊柱的随机CT扫描进行研究后,计算辐射剂量和预估癌症风险率。上述这些部位的扫描检查数量占所有CT扫描数量的95%以上。预估的癌症终生归因风险率计算基于《电离辐射的生物学效应》(BEIR)的第七次报告———针对乳腺癌、结肠癌、肝癌、肺癌、卵巢癌、前列腺癌、胃癌、甲状腺癌、膀胱癌、子宫癌和白血病——以及使用类似方法开发出的针对口腔、食管、直肠、胰腺、肾及脑部肿瘤的计算机模型,这些肿瘤在美国所有癌症病例中所占的比例高达85%。结果在1996年至2005年间,5岁以下儿童CT检查率增加了1倍而5到14岁儿童使用率增加了2倍;2006至2007年间,儿童CT检查率保持稳定,而之后开始下降。有效剂量幅度为每次扫描0.03到69.2毫希弗。有效剂量在20毫希弗或以上的检查出现在14%~25%的腹部或盆腔扫描、6%~14%的脊柱扫描以及3%~8%的胸部扫描。与年长儿童及男性患儿相比,低龄者及女性患儿终生罹患实体癌症的风险更高;接受腹部、盆腔或脊柱CT扫描的患儿也较接受其他部位CT扫描更易引发实体癌。对于女性患儿,根据年龄不同,不同部位CT扫描辐射诱导实体癌发生情况分别为每300到390例腹部或盆腔扫描、每330到480例胸部扫描以及每270到800例脊柱扫描。对于5岁以下的患儿,进行头部CT扫描导致白血病的风险最高,达1.9/10000。美国卫生保健机构每年共对儿童各器官进行4百万次的CT扫描,这可能导致未来约4870例癌症病例。如果将最高辐射剂量降低25%,就可减少2090例癌症病例,相当于患癌风险降低43%。取消不必要的扫描,可减少3020例癌症病例,相当于患癌风险降低62%。结论CT在儿科使用的增加以及放射剂量的较大变化,导致很多儿童接受了高剂量检查。降低最高照射剂量1/4的策略可以显著地减少辐射诱发癌症的数量。 | Miglioretti DL Johnson E Williams A 陈斯乐 张信华 | 2014 | 消化肿瘤杂志(电子版)2014，0，1： | 2 |
