| 1 | CONSORT 2010说明与详述:报告平行对照随机临床试验指南的更新显示文摘大量证据显示随机对照临床试验(randomised controlled trial,RCT)的报告质量不理想。报告不透明,则读者既不能评判试验结果是否真实可靠,也不能从中提取可用于系统综述的信息。最近的方法学分析表明,报告不充分和设计不合理与对治疗效果产生评价偏倚有关。这种系统误差对RCT损害严重,而RCT正是以其能减少或避免偏倚而被视为评价干预措施的金标准。为了提高RCT的报告质量,一个由专家和编辑组成的工作组制定了临床试验报告的统一标准(Consolidated Standards of Reporting Trials,CONSORT)声明。CONSORT声明于1996年首次发表,并于2001年更新。声明由对照检查清单和流程图组成,供作者在报告RCT时使用。许多核心医学期刊和主要国际性编辑组织都已认可CONSORT声明。该声明促进了对RCT的严格评价和解释。2001年,在对CONSORT进行修订时,人们就已经清楚地认识到,解释和说明制定CONSORT声明的原理,有助于研究人员等撰写或评价临床试验报告。一篇CONSORT说明与详述文章于2001年同2001版CONSORT声明一起发表。2007年1月的专家会议之后,对CONSORT声明作了进一步修订并已发表,即'CONSORT2010声明'。这次更新对原版对照检查清单作了文字上的修改,使其更为明晰,并收入了与一些新近才认识到的主题相关的建议,如选择性报告结局产生的偏倚。说明与详述文件旨在加强人们对CONSORT声明的理解、应用和传播,这次也作了大量修订,对每一项新增或更新的清单条目的含义和增改理由进行了解释,提供了优秀的报告实例,还尽可能地提供了相关的经验性研究的参考文献。文中收入了若干流程图实例。'CONSORT2010声明'、其说明与详述文件,以及相关网站(www.consort-statement.org),对于改进随机临床试验报告必将有所裨益。 | David Moher Sally Hopewell Kenneth F Schulz Victor Montori Peter C Gφtzsche P J Devereaux Diana Elbourne Matthias Egger Douglas G Altman 周庆辉 卞兆祥 刘建平 | 2010 | 中西医结合学报2010，8，8： | 318 |
| 2 | 森林火险等级预报系统评述显示文摘对当前世界上主要的森林火险等级系统进行了综述,包括加拿大、美国、澳大利亚以及其他一些国家的森林火险等级系统。对主要森林火险等级系统的组成、结构和发展过程进行了比较,讨论了这些系统应用的局限性。比较了世界上3个应用比较普遍的森林火险等级系统的发展、可燃物类型、输入因子、输出因子和应用范围,认为发展中国的森林火险等级系统采用加拿大的森林火险等级系统(CFFDRS)的技术比较合适。我们可直接应用CFFDRS,然后根据当地气候和可燃物类型对火险等级系统进行校正。 | 田晓瑞 Douglas J Mcrae 张有慧 | 2006 | 世界林业研究2006，19，2： | 48 |
| 3 | 木质素生物合成及其基因调控的研究进展显示文摘木质素是地球上数量仅次于纤维素的有机物,在植物生长发育中具有重要的生物学功能,也是生物质能源的来源之一,但在制浆造纸过程中,将木材原料中木质素与纤维素分离,不仅能耗高,成本高,而且废弃物还污染环境。林木木质素改良对于提高纸浆得率和质量、降低造纸经济成本以及环境保护,都具有重要意义。文中介绍了木质素生物合成途径及其基因调控的研究进展,此外,还介绍了木质素生物合成基因调控的研究趋势,主要是木质素特异性启动子、双价和多基因结构的共抑制以及转录因子的调控。 | 李金花 张绮纹 牛正田 卢孟柱 Carl J Douglas | 2007 | 世界林业研究2007，20，1： | 18 |
| 4 | Increased hepcidin expression in colorectal carcinogenesis显示文摘AIM:To investigate whether the iron stores regulator hepcidin is implicated in colon cancer-associated anae- mia and whether it might have a role in colorectal car- cinogenesis. METHODS: Mass spectrometry (MALDI-TOF MS and SELDI-TOF MS) was employed to measure hepcidin in urine collected from 56 patients with colorectal cancer. Quantitative Real Time RT-PCR was utilised to determine hepcidin mRNA expression in colorectal cancer tissue. Hepcidin cellular localisation was determined using im- munohistochemistry. RESULTS: We demonstrate that whilst urinary hepcidin expression was not correlated with anaemia it was posi- tively associated with increasing T-stage of colorectal cancer (P < 0.05). Furthermore, we report that hepcidin mRNA is expressed in 34% of colorectal cancer tissue specimens and was correlated with ferroportin repres- sion. This was supported by hepcidin immunoreactivity in colorectal cancer tissue. CONCLUSION: We demonstrate that systemic hepcidin expression is unlikely to be the cause of the systemic anaemia associated with colorectal cancer. However, we demonstrate for the first time that hepcidin is expressed by colorectal cancer tissue and that this may represent a novel oncogenic signalling mechanism. | Douglas G Ward Keith Roberts Matthew J Brookes Howard Joy Ashley Martin Tariq Ismail Robert Spychal Tariq Iqbal Chris Tselepis | 2008 | World Journal of Gastroenterology2008，14，9： | 12 |
| 5 | 加强流行病学中观察性研究报告质量(STROBE)声明:观察性研究报告规范显示文摘很多生物医学研究都是观察性的。但对这类研究的报告却通常不完整,从而限制了对其优缺点及普适性的评价。“加强流行病学中观察性研究报告质量(STROBE)”工作组针对一篇完整明确的观察性研究报告应包括的内容提供了一套建议。建议涵盖了流行病学研究的三种主要设计类型:队列设计、病例对照设计和横断面设计。2004年9月,我们召开了为期2天的研讨会,与会的方法学专家、研究人员和期刊编辑共同起草了一份观察性研究报告应纳入的条目清单草案。此后,又通过协调小组数次会议及与有关人员电子邮件讨论等对该草案进行了修改,纳入了经验性证据和方法学方面的意见。通过研讨会及之后反复的咨询和修订,我们制定出了一个包含22个条目的清单(STROBE声明),分为论文的题目、摘要、引言、方法、结果和讨论等部分。其中18个条目适用于所有三种主要的观察性研究设计,其余4个条目则专门用于队列、病例一对照或横断面设计。详细的解释和示范文件已另行发表,在《公共科学图书馆一医学》(PLoS Medicine)、《内科学年报》(Annalsof Internal Medicine)和《流行病学》(Epidemiology)的网站可以免费获得。我们希望STROBE声明能有助于改善观察性研究报告的质量。 | Erikvon Elm Douglas G Altman Matthias Egger Stuart J Pocock Peter C G tzsche Jan P Vandenbroucke 赵乐(译) 邹光勇(审) 杜怀东(审) | 2008 | 世界临床医学2008，2，1： | 12 |
| 6 | Gastroenterologist perceptions of faecal microbiota transplantation显示文摘AIM: To explore gastroenterologist perceptions towards and experience with faecal microbiota transplantation(FMT).METHODS: A questionnaire survey consisting of 17 questions was created to assess gastroenterologists' attitude towards and experience with FMT. This was anonymously distributed in hard copy format amongst attendees at gastroenterology meetings in Australia between October 2013 and April 2014. Basic descriptive statistical analyses were performed.RESULTS: Fifty-two clinicians participated. Twenty one percent had previously referred patients for FMT,8% more than once. Ninety percent would refer patients with Clostridium difficile infection(CDI) for FMT if easily available,37% for ulcerative colitis,13% for Crohn's disease and 6% for irritable bowel syndrome. Six percent would not refer any indication,including recurrent CDI. Eighty-six percent would enroll patients in FMT clinical trials. Thirty-seven percent considered the optimal mode of FMT administration transcolonoscopic,17% nasoduodenal,13% enema and 8% oral capsule. The greatest concerns regarding FMT were: 42% lack of evidence,12% infection risk,10% non infectious adverse effects/lack of safety data,10% aesthetic,10% lack of efficacy,4% disease exacerbation,and 2% inappropriate use; 6% had no concerns. Seventy seven percent believed there is a lack of accessibility while 52% had an interest in learning how to provide FMT. Only 6% offered FMT at their institution.CONCLUSION: Despite general enthusiasm,most gastroenterologists have limited experience with,or access to,FMT. The greatest concerns were lack of supportive evidence and safety issues. However a significant proportion would refer indications other than CDI for FMT despite insufficient evidence. These data provide guidance on where education and training are required. | Sudarshan Paramsothy Alissa J Walsh Thomas Borody Douglas Samuel Johan van den Bogaerde Rupert WL Leong Susan Connor Watson Ng Hazel M Mitchell Nadeem O Kaakoush Michael A Kamm | 2015 | World Journal of Gastroenterology2015，21，38： | 5 |
| 7 | 植物凝集素串联法富集纯化血清多个亚糖蛋白质组显示文摘蛋白质糖基化修饰是哺乳动物中最为常见的一种翻译后修饰,蛋白质的寡糖侧链具有重要的生物学意义,如蛋白质分子间及细胞间相互作用、识别、肿瘤侵袭与转移等.本实验应用寡甘露糖型亲合层析柱、唾液酸型层析柱和O-连接糖蛋白亲合层析柱从血清中序列性提取寡甘露糖型、唾液酸型的N-连接糖蛋白及O-连接的糖蛋白,一维和二维电泳图谱显示血清各亚糖蛋白组图谱差异,并对富集的唾液酸型糖蛋白质组的二维电泳图谱中12个显著的差异蛋白质点进行质谱检测,鉴定出的14个蛋白均为N-连接糖蛋白.植物凝集素序列性提取血清各亚糖蛋白质组,显著减小了血清蛋白质组的复杂性和血清蛋白浓度波动范围,提高了质谱鉴定血清中对疾病诊断和疗效监测具有重要意义的生物标志物的灵敏性. | 齐义军 王攀 牛保华 侯艳芳 晁玮霞 WARD Douglas JOHSON Philip J 马远方 | 2011 | 中国科学:生命科学2011，41，5： | 3 |
| 8 | Reuse of liver grafts following the brain death of the initial recipient显示文摘AIM: To determine if there is a reasonable prospect of success of a re-use liver transplantation.METHODS: We systematically searched for reports of liver graft re-use using electronic searches of PubMed and Web of Knowledge. We performed hand searches of references lists of articles reporting re-use of grafts.RESULTS: A systematic review of the literature reveals 28 liver transplantations using previously transplanted grafts. First and second recipients ranged in age from 4 to 72 years and 29 to 62 years respectively. Liver disease in the first recipient was varied including 5(18%) patients with fulminant liver failure who died subsequently of cerebral edema. The second transplanta-tion was performed after a median interval of 5 d(one day-13 years). Viral hepatitis was present in 3(11%) of the initial recipients and in 8(29%) of final recipients. Hepatocellular carcinoma was present in 6(21%) of the final recipients. Early survival after the final transplantation was 93%, whereas long-term survival was 78% with a mean follow-up of 23.3(3-120) mo.CONCLUSION: Outcomes of transplantation using previously transplanted grafts in this select population are similar to those seen with conventional grafts. | Hideaki Tanaka Vivian C McAlister Mark A Levstik Cameron N Ghent Paul J Marotta Douglas Quan William J Wall | 2014 | World Journal of Hepatology2014，6，6： | 3 |
| 9 | Reinterpretation of histology of proximal colon polyps called hyperplastic in 2001显示文摘AIM: To evaluate how proximal colon polyps interpreted as hyperplastic polyps in 2001 would be interpreted by expert pathologists in 2007. METHODS: Forty consecutive proximal colon polyps ≥ 5 mm in size, removed in 2001, and originally interpreted as hyperplastic polyps by general pathologists at Indiana University, were reviewed in 2007 by 3 GI pathologists. RESULTS: The gastrointestinal (GI) pathologists interpreted 85%, 43% and 30% of the polyps as sessile serrated polyps (sessile serrated adenomas). The overall Kappa was 0.16. When diagnoses were compared in pairs, Kappa values were 0.38 and 0.25 (fair agreement) and 0.14 (slight agreement). CONCLUSION: Many polyps interpreted as hyperplastic in 2001 were considered sessile serrated lesions by GI pathologists in 2007, but there is substantial inter-observer variation amongst GI pathologists. | Omer Khalid Sofyan Radaideh Oscar W Cummings Michael J O'Brien John R Goldblum Douglas K Rex | 2009 | World Journal of Gastroenterology2009，15，30： | 3 |
| 10 | Nrf2 is required for normal postnatal bone acquisition in mice显示文摘A large body of literature suggests that bone metabolism is susceptible to the ill effects of reactive species that accumulate in the body and cause cellular dysfunction. One of the body's front lines in defense against such damage is the transcription factor, Nrf2. This transcription factor regulates a plethora of antioxidant and cellular defense pathways to protect cells from such damage. Despite the breadth of knowledge of both the function of Nrf2 and the effects of reactive species in bone metabolism, the direct role of Nrf2 in skeletal biology has yet to be thoroughly examined. Thus, in the current study, we have examined the role of Nrf2 in postnatal bone metabolism in mice. Mice lacking Nrf2(Nrf22/2) exhibited a marked deficit in postnatal bone acquisition,which was most severe at 3 weeks of age when osteoblast numbers were 12-fold less than observed in control animals. While primary osteoblasts from Nrf22/2mice functioned normally in vitro, the colony forming capacity of bone marrow stromal cells(BMSCs) from these mice was significantly reduced compared to controls.This defect could be rescued through treatment with the radical scavenger N-acetyl cysteine(NAC), suggesting that increased reactive species stress might impair early osteoblastogenesis in BMSCs and lead to the failure of bone acquisition observed in Nrf22/2animals. Taken together, these studies suggest Nrf2 represents a key pathway in regulating bone metabolism, which may provide future therapeutic targets to treat osteoporosis. | Jung-Hyun Kim Vandana Singhal Shyam Biswal Rajesh K Thimmulappa Douglas J Di Girolamo | 2014 | Bone Research2014，2，4： | 3 |

| 12 | Is iron overload in alcohol-related cirrhosis mediated by hepcidin?显示文摘In this case report we describe the relationship between ferritin levels and hepcidin in a patient with alcohol-related spur cell anemia who underwent liver transplantation.We demonstrate a reciprocal relation-ship between serum or urinary hepcidin and serum ferritin,which indicates that inadequate hepcidin production by the diseased liver is associated with elevated serum ferritin.The ferritin level falls with increasing hepcidin production after transplantation.Neither inflammatory indices(IL6)nor erythropoietin appear to be related to hepcidin expression in this case.We suggest that inappropriately low hepcidin production by the cirrhotic liver may contribute substantially to elevated tissue iron stores in cirrhosis and speculate that hepcidin replacement in these patients may be of therapeutic benefi t in the future. | Tariq Iqbal Azzam Diab Douglas G Ward Matthew J Brookes Chris Tselepis Jim Murray Elwyn Elias | 2009 | World Journal of Gastroenterology2009，15，46： | 2 |

| 14 | Diagnostic and therapeutic role of endoscopic retrograde cholangiopancreatography in biliary rhabdomyosarcoma显示文摘Biliary rhabdomyosarcoma (BRMS) is an uncommon childhood malignancy which has been managed surgically. We present a case of a 3-year-old boy with BRMS, in whom endoscopic retrograde cholangiopancreatography (ERCP) was successfully used both diagnostically and therapeutically, thus obviating the need for surgery and its attendant risks of morbidity and mortality. We conclude that ERCP is an effective alternative to surgery for BRMS in some patients. | Ryan W Himes Isaac Raijman Milton J Finegold Heidi V Russell Douglas S Fishman | 2008 | World Journal of Gastroenterology2008，14，30： | 2 |
