1CONSORT 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江南造山带雪峰隆起区元古宙浊积岩沉积构造背景的地球化学制约显示文摘江南造山带雪峰隆起区元古宙浊积岩的地球化学组成良好地反映了沉积盆地的板块构造性质,并为解释区域大地构造的性质和演化提供了有用的信息。中元古代冷家溪群和新元古代板溪群(包括下部马底驿组和上部五强溪组)地层在主元素成分上无明显区别,总体上以中等SiO2含量和K2O/Na2O比值以及较高的(Fe2O3+MgO)含量为特征。稀土元素球粒陨石标准化曲线与典型的后太古宙页岩(如PAAS或NASC)和上陆壳相似,以轻稀土富集、显著的铕负异常和重稀土平坦为特征。大离子亲石元素和铁镁族元素的含量中等。主元素和微量元素特征指示了研究区元古宙浊积岩很可能代表了一套活动大陆边缘弧后沉积盆地的产物。陆内裂谷盆地模式对于解释新元古代华南地区的构造性质和演化可能并不合适。华夏陆块与扬子陆块的拼接以及Rodinia超大陆的最终形成可能发生在约0.8Ga左右的晋宁(雪峰)造山运动期,而不是全球Grenville造山期末的四堡(东安)运动期。顾雪祥 刘建明 Oskar Schulz Franz Vavtar 郑明华 2003地球化学2003,32,5:53

6Generating optical orbital angular momentum at visible wavelengths using a plasmonic metasurface显示文摘Light beams with a helical phase-front possess orbital angular momentum along their direction of propagation in addition to the spin angular momentum that describes their polarisation.Until recently,it was thought that these two‘rotational’motions of light were largely independent and could not be coupled during light–matter interactions.However,it is now known that interactions with carefully designed complex media can result in spin-to-orbit coupling,where a change of the spin angular momentum will modify the orbital angular momentum and vice versa.In this work,we propose and demonstrate that the birefringence of plasmonic nanostructures can be wielded to transform circularly polarised light into light carrying orbital angular momentum.A device operating at visible wavelengths is designed from a space-variant array of subwavelength plasmonic nano-antennas.Experiment confirms that circularly polarised light transmitted through the device is imbued with orbital angular momentum of 62'(with conversion efficiency of at least 1%).This technology paves the way towards ultrathin orbital angular momentum generators that could be integrated into applications for spectroscopy,nanoscale sensing and classical or quantum communications using integrated photonic devices.Ebrahim Karimi Sebastian A Schulz Israel De Leon Hammam Qassim Jeremy Upham Robert W Boyd 2014Light(Science & Applications)2014,3,1:39
7UGT1A1 gene polymorphism: Impact on toxicity and efficacy of irinotecan-based regimens in metastatic colorectal cancer显示文摘AIM: To investigate the correlation between uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) gene polymorphisms and irinotecan-associated side effects and parameters of drug efficacy in patients with metastatic colorectal cancer (mCRC) receiving a low-dose weekly irinotecan chemotherapeutic regimen. METHODS: Genotypes were retrospectively evaluated by gene scan analysis on the ABI 310 sequencer of the TATAA box in the promoter region of the UGT1A1 gene in blood samples from 105 patients who had received 1st line irinotecan-based chemotherapy for mCRC. RESULTS: The distribution of the genotypes was as follows: wild type genotype (WT) (6/6 ) 39.0%, heterozygous genotype (6/7) 49.5%, and homozygous genotype (7/7) 9.5%. The overall response rate (OR) was similar between patients carrying the (6/7, 7/7) or the WT genotype (6/6) (44.3% vs 43.2%, P = 0.75). Neither time to progression [(TTP) 8.1 vs 8.2 mo, P = 0.97] nor overall survival [(OS) 21.2 vs 18.9 mo, P = 0.73] differed significantly in patients who carried the(6/6) when compared to the (6/7, 7/7) genotype. No significant differences in toxicity were observed: Grade 3 and 4 delayed diarrhoea [(6/7, 7/7) vs (6/6); 13.0% vs 6.2%, P =0.08], treatment delays [(6/7, 7/7) vs (6/6); 25.1% vs 19.3%, P = 0.24] or dose reductions [(6/7, 7/7) vs (6/6); 21.5% vs 27.2%, P = 0.07].CONCLUSION: This analysis demonstrates the non-significant influence of the UGT1A1 gene polymorphism on efficacy and rate of irinotecan-associated toxicity in mCRC patients receiving low-dose irinotecan based chemotherapy.Christoph Schulz Volker Heinemann Andreas Schalhorn Nikolas Moosmann Thomas Zwingers Stefan Boeck Clemens Giessen Hans-Joachim Stemmler 2009World Journal of Gastroenterology2009,15,40:31

14Herbal traditional Chinese medicine and its evidence base in gastrointestinal disorders显示文摘Herbal traditional Chinese medicine(TCM) is used to treat several ailments, but its efficiency is poorly documented and hence debated, as opposed to modern medicine commonly providinge ffective therapies. The aim of this review article is to present a practical reference guide on the role of herbal TCM in managing gastrointestinal disorders, supported by systematic reviews and evidence based trials. A literature search using herbal TCM combined with terms for gastrointestinal disorders in Pub Med and the Cochrane database identified publications of herbal TCM trials. Results were analyzed for study type, inclusion criteria, and outcome parameters. Quality of placebo controlled, randomized, double-blind clinical trials was poor, mostly neglecting stringent evidence based diagnostic and therapeutic criteria. Accordingly, appropriate Cochrane reviews and meta-analyses were limited and failed to support valid, clinically relevant evidence based efficiency of herbal TCM in gastrointestinal diseases, including gastroesophageal reflux disease, gastric or duodenal ulcer, dyspepsia, irritable bowel syndrome, ulcerative colitis, and Crohn's disease. In conclusion, the use of herbal TCM to treat various diseases has an interesting philosophical background with a long history, but it received increasing skepticism due to the lack of evidence based efficiency as shown by high quality trials; this has now been summarized for gastrointestinal disorders, with TCM not recommended for most gastrointestinal diseases. Future studies should focus on placebo controlled, randomized, double-blind clinical trials, herbal product quality and standard criteria for diagnosis, treatment, outcome, and assessment of adverse herb reactions. This approach will provide figures of risk/benefit profiles that hopefully are positive for at least some treatment modalities of herbal TCM. Proponents of modern herbal TCM best face these promising challenges of pragmaticmodern medicine by bridging the gap between the two medicinal cultures.Rolf Teschke Albrecht Wolff Christian Frenzel Axel Eickhoff Johannes Schulze 2015World Journal of Gastroenterology2015,21,15:19
15Current biomarkers for hepatocellular carcinoma: Surveillance, diagnosis and prediction of prognosis显示文摘Biomarkers for surveillance, diagnosis and prediction of prognosis in patients with hepatocellular carcinoma(HCC) are currently not ready for introduction into clinical practice because of limited sensitivity and specificity. Especially for the early detection of small HCC novel biomarkers are needed to improve the current effectiveness of screening performed byultrasound. The use of high-throughput technologies in hepatocellular research allows to identify molecules involved in the complex pathways in hepatocarcinogenesis. Several invasive and non-invasive biomarkers have been identified already and have been evaluated in different clinical settings. Gene signatures with prognostic potential have been identified by gene expression profiling from tumor tissue. However, a single 'all-in-one' biomarker that fits all-surveillance, diagnosis, prediction of prognosis-has not been found so far. The future of biomarkers most probably lies in a combination of non-invasive biomarkers, imaging and clinical parameters in a surveillance setting. Molecular profiling of tumorous and non-tumorous liver tissue may allow a prediction of prognosis for the individual patient and hopefully clear the way for individual treatment approaches. This article gives an overview on current developments in biomarker research in HCC with a focus on currently available and novel biomarkers, in particular on micro RNA.Kerstin Schütte Christian Schulz Alexander Link Peter Malfertheiner 2015World Journal of Hepatology2015,7,2:18
16湖南沃溪W-Sb-Au矿床成因的流体包裹体证据显示文摘系统研究了沃溪W-Sb-Au矿床层状矿体的流体包裹体特征,均一温度集中在120~180℃,盐度变化于2.9%~8.9%NaCl之间,由包裹体均一温度与盐度计算得出的流体密度介于0.94~0.96g/cm^3。流体包裹体稀土元素地球化学组成表明,成矿流体为一种进化的海水,即海水在海底下沉积柱循环过程中萃取矿质,形成120~180℃温度的低密度成矿流体。当其回返上升到海底后,形成悬浮热液柱,并与冷海水逐渐掺和,发生化学和机械-化学沉积,在海底形成层状矿体。流体包裹体均一温度和盐度的变化范围与很多沉积喷流(SEDEX)矿床极为相似,暗示与这些矿床具有相似的成因机制。同一矿层、条带状矿石中同一条带的石英中包裹体均一温度和盐度的规律性变化,支持沃溪W-Sb-Au矿床的同生热水沉积成因观点。董树义 顾雪祥 Oskar Schulz Franz Vavtar 刘建明 郑明华 程文斌 2008地质学报2008,82,5:16
17Long-term follow-up after complete ablation of Barrett's esophagus with argon plasma coagulation显示文摘AIM: To report the long-term outcome of patients after complete ablation of non-neoplastic Barrett's esophagus (BE) with respect to BE relapse and development of intraepithelial neoplasia or esophageal adenocarcinoma.METHODS: In 70 patients with histologically proven nonneoplastic BE, complete BE ablation was achieved by argon plasma coagulation (APC) and high-dose proton pump inhibitor therapy (120 mg omeprazole daily). Sixty-six patients (94.4%) underwent further surveillance endoscopy. At each surveillance endoscopy four-quadrant biopsies were taken from the neo-squamous epithelium at 2 cm intervals depending on the pre-treatment length of BE mucosa beginning at the neo-Z-line, and from any endoscopically suspicious lesion.RESULTS: The median follow-up of 66 patients was 51 mo (range 9-85 mo) giving a total of 280.5 patient years.A mean of 6 biopsies were taken during surveillance endoscopies. In 13 patients (19.7%) tongues or islands suspicious for BE were found during endoscopy. In 8 of these patients (12.1%) non-neoplastic BE relapse was confirmed histologically giving a histological relapse rate of 3% per year. In none of the patients, intraepithelial neoplasia nor an esophageal adenocarcinoma was detected.Logistic regression analysis identified endoscopic detection of islands or tongues as the only positive predictor of BE relapse (P = 0.0004).CONCLUSION: The long-term relapse rate of nonneoplastic BE following complete ablation with high-power APC is low (3% per year).Ahmed Madisch Stephan Miehike Ekkehard Bayerdoerffer Birgit Wiedemann David Antos Anke Sievert Michael Vieth Manfred Stolte Heinrich Schulz 2005World Journal of Gastroenterology2005,11,8:14
18CONSORT声明:提高平行随机试验报告质量的修订建议显示文摘要想理解随机对照试验(RCT)的结果,读者必须了解其设计、实施、分析和解释。这种目标只能通过作者的完全透明而实现。尽管做了几十年的教育努力,RCTs的报告方法仍然需要改进。调查人员和编辑们为了帮助作者提高报告的质量,通过使用核对表和流程图的形式开发了原CONSORT(报告试验的强化标准)。这里介绍的修改过的CONSORT声明,融合了新的证据,听取了对早期声明的批评意见。核对表的项目涵盖了文题、摘要、引言、方法、结果和讨论部分的内容。修订的核对表包括精选的22个项目,经验证据表明不报告这些信息会对疗效产生错误估计,或者需要这些信息以判断发现的可靠性和相关性。我们有意安插了流程图,以便描述受试者参与RCT的经过。修订的流程图描述了试验的4个阶段(登记、干预分配、随访和分析)的信息。流程图清楚地显示了每个干预组的受试者数量,包含在资料的初步分析中。包含这些数字便于读者判断作者是否采用了意向性治疗分析法(intentiontotreat)。总之,CONSORT声明旨在提高报告RCT的质量,便于读者了解试验的实施,以及评价其结果的有效性。David Moher Kenneth F Schulz Douglas G.Altman 代表CONSORT小组 汪谋岳 2005中国中西医结合杂志2005,25,7:13
19基于电磁阀的喷嘴直接注入式农药喷洒系统显示文摘设计了一种喷嘴直接注入式农药喷洒系统。通过与传统喷雾机械比较,简述了喷嘴直接注入式喷雾系统的结构和喷雾执行单元。为了实现农药定量注入,设计一种基于电磁原理的快速响应阀,并论述其工作原理和闭环控制方式。通过试验测试了喷雾执行单元的喷雾特性和喷杆组内各喷雾单元的一致性。结果表明在一定喷洒速率范围内,喷雾执行单元的喷水量和水压强存在多项式关系,农药注入量和PWM信号的高电平时间存在指数关系,其决定系数均高于0.9,并且同一喷杆组内6个喷雾单元的喷雾效果大体一致。蔡祥 Walgenbach Martin Doerpmund Malte Schulze Lammers Peter 孙宇瑞 2013农业机械学报2013,44,6:13
20An Improved Frequency Domain Technique for Determining Soil Water Content显示文摘For many years a soil water content sensor with low cost, reliability and sufficient accuracy has been desirable. Thus, an improved measurement method based on the frequency domain (FD) principle for determining soil water content was considered. Unlike other measurement principles, a new measurable index, η, which was independent of the output impedance and the amplitude of the oscillator while relying on the electrical impedance of a multi-pin probe, was pro- posed. Moreover, a model for processing the impedance of the multi-pin soil probe was developed, and several important electrical parameters for establishing their operating ranges applicable to this probe were evaluated. In order to confirm the theoretical analysis, an experiment was conducted with a 4-pin probe. Using the developed model, the relationship between the proposed index η and soil volumetric water content was shown to be linear (R2 = 0.9921). Thus, as the measurable index, η seemed satisfactory.SUN Yu-Rui MA Dao-Kun LIN Jian-Hui P. SCHULZE LAMMERS L. DAMEROW 2005Pedosphere2005,15,6:13
