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
3Machine-learned interatomic potentials by active learning:amorphous and liquid hafnium dioxide显示文摘We propose an active learning scheme for automatically sampling a minimum number of uncorrelated configurations for fitting the Gaussian Approximation Potential(GAP).Our active learning scheme consists of an unsupervised machine learning(ML)scheme coupled with a Bayesian optimization technique that evaluates the GAP model.We apply this scheme to a Hafnium dioxide(HfO2)dataset generated from a“melt-quench”ab initio molecular dynamics(AIMD)protocol.Our results show that the active learning scheme,with no prior knowledge of the dataset,is able to extract a configuration that reaches the required energy fit tolerance.Further,molecular dynamics(MD)simulations performed using this active learned GAP model on 6144 atom systems of amorphous and liquid state elucidate the structural properties of HfO2 with near ab initio precision and quench rates(i.e.,1.0 K/ps)not accessible via AIMD.The melt and amorphous X-ray structural factors generated from our simulation are in good agreement with experiment.In addition,the calculated diffusion constants are in good agreement with previous ab initio studies.Ganesh Sivaraman Anand Narayanan Krishnamoorthy Matthias Baur Christian Holm Marius Stan Gábor Csányi Chris Benmore Álvaro Vázquez-Mayagoitia 2020npj Computational Materials2020,,1:10
4Matched-pair analysis of postoperative morbidity and mortality for pancreaticogastrostomy and pancreaticojejunostomy using mattress sutures in soft pancreatic tissue remnants显示文摘BACKGROUND:After pancreaticoduodenectomy,the incidence of postoperative pancreatic fistula remains high,especially in patients with 'soft' pancreatic tissue remnants.No 'gold standard' surgical technique for pancreaticoenteric anastomosis has been established.This study aimed to compare the postoperative morbidity and mortality of pancreaticogastrostomy and pancreaticojejunostomy for 'soft' pancreatic tissue remnants using modified mattress sutures.METHODS:Seventy-five patients who had undergone pancreaticogastrostomy and 75 who had undergone pancreaticojejunostomy after pancreaticoduodenectomy between 2002 and 2008 were retrospectively compared using matched-pair analysis.A modified mattress suture technique was used for the pancreaticoenteric anastomosis.Patients with an underlying 'hard' pancreatic tissue remnant,as in chronic pancreatitis,were excluded.Both groups were homogeneous for age,gender,and underlying disease.Postoperative morbidity,mortality,and preoperative and operative data were analyzed.RESULTS:There were no significant differences between the groups for the incidence of postoperative pancreatic fistula (10.7% in both).Postoperative morbidity and mortality,median operation time,median length of hospital stay,intraoperative blood loss,and the amount of intraoperatively transfused erythrocyte concentrates also did not significantly differ between the groups.Patient age >65 years (P=0.017),operation time >350minutes (P=0.001),and intraoperative transfusion of erythrocyte concentrates (P=0.038) were identified as risk factors for postoperative morbidity.CONCLUSIONS:Our results showed no significant differences between the groups in the pancreaticogastrostomy and pancreaticojejunostomy anastomosis techniques using mattress sutures for 'soft' pancreatic tissue remnants.In our experience,the mattress sutures are safe and simple to use,and pancreaticogastrostomy in particular is feasible and easy to learn,with good endoscopic accessibility to the anastomosis region.However,the location of the anastomosis and the surgical technique need to be individually evaluated to further reduce the incidence of postoperative pancreatic fistula.Fritz Klein Marcus Bahra Matthias Glanemann Wladimir Faber Peter Warnick Andreas Andreou Safak Gül Dietmar Jacob 2012Hepatobiliary & Pancreatic Diseases International2012,11,1:9

6Machine-learned multi-system surrogate models for materials prediction显示文摘Surrogate machine-learning models are transforming computational materials science by predicting properties of materials with the accuracy of ab initio methods at a fraction of the computational cost.We demonstrate surrogate models that simultaneously interpolate energies of different materials on a dataset of 10 binary alloys(AgCu,AlFe,AlMg,AlNi,AlTi,CoNi,CuFe,CuNi,FeV,and NbNi)with 10 different species and all possible fcc,bcc,and hcp structures up to eight atoms in the unit cell,15,950 structures in total.We find that the deviation of prediction errors when increasing the number of simultaneously modeled alloys is<1 meV/atom.Several state-of-the-art materials representations and learning algorithms were found to qualitatively agree on the prediction errors of formation enthalpy with relative errors of<2.5% for all systems.Chandramouli Nyshadham Matthias Rupp Brayden Bekker Alexander V.Shapeev Tim Mueller Conrad W.Rosenbrock Gábor Csányi David W.Wingate Gus L.W.Hart 2019npj Computational Materials2019,,1:8

9Heme oxygenase-1 overexpression increases liver injury after bile duct ligation in rats显示文摘AIM: To investigate the effects of heme oxygenase-1 (HO-1) against oxidant-induced injury caused by bile duct ligation (BDL). METHODS: Either cobalt protoporphyrin (CoPP), a HO-1 inducer, or saline were injected intraperitoneally in male SD-rats. Three days later, BDL or sham-operations were performed. Rats were sacrificed 3 wk after BDL and livers were harvested for histology. Fibrosis was evaluated by sirius red staining and image analysis. Alpha-smooth muscular actin, which indicates activation of stellate cells, was detected by immunohistochemical staining, and cytokine and collagen-Ⅰα (Col-Ⅰα) mRNA expression was detected using RNase protection assays. RESULTS: Serum alanine transaminase increased 8-fold above normal levels one day after BDL. Surprisingly, enzyme release was not reduced in rats receiving CoPP. Liver fibrosis was evaluated 3 wk after BDL and the sirius red-positive area was found to be increased to about 7.8%. However, in CoPP pretreated rats sirius red- positive areas were increased to about 11.7% after BDL. Collagen-Ⅰα and TGF-β mRNA increased significantly by BDL. Again, this effect was increased by HO-1 overexpression.CONCLUSION: Hepatic fibrosis due to BDL is not reduced by the HO-1 inducer CoPP. In contrast, HO-1 overexpression increases liver injury in rats under conditions of experimental chronic cholestasis.Matthias Froh Lars Conzelmann Peter Walbrun Susanne Netter Reiner Wiest Michael D Wheeler Mark Lehnert Takehiko Uesugi Jurgen Scholmerich Ronald G Thurman 2007World Journal of Gastroenterology2007,13,25:4

11Role of HSP-90 for increased nNOS-mediated vasodilation in mesenteric arteries in portal hypertension显示文摘AIM:To explore the role of heat shock protein-90 (HSP-90) for nitrergic vasorelaxation in the splanchnic circulation in rats with and without portal hypertension. METHODS: Neuronal nitric oxide synthase (nNOS) and HSP-90 were analyzed by immunofluorescence, western blotting and co-immunoprecipitation in the mesenteric vasculature and isolated nerves of portal-vein-ligated (PVL) rats and sham operated rats. In vitro perfused de-endothelialized mesenteric arterial vasculature was preconstricted with norepinephrine (EC80) and tested for nNOS-mediated vasorelaxation by periarterial nerve stimulation (PNS, 2-12 Hz, 45V) before and after incubation with geldanamycin (specific inhibitor of HSP-90 signalling, 3 μg/mL) or L-NAME (non-specific NOSblocker, 10-4 mol/L). RESULTS: nNOS and HSP-90 expression was significantly increased in mesenteric nerves from PVL as compared to sham rats. Moreover, nNOS and HSP-90 were visualized in mesenteric nerves by immunofluorescence and immunoprecipitation of nNOS co-immunoprecitated HSP-90 in sham and PVL rats. PNS induced a frequencydependent vasorelaxation which was more pronounced in PVL as compared to sham rats. L-NAME and geldanamycin markedly reduced nNOS-mediated vasorelaxation abrogating differences between the study groups. The effect of L-NAME and geldanamycin on nNOS-mediated vasorelaxation was significantly greater in PVL than in sham animals. However, no difference in magnitude of effect between L-NAME and geldanamycin was noted. CONCLUSION: HSP-90 acts as a signalling mediator of nNOS-dependent nerve mediated vascular responses in mesenteric arteries, and the increased nitrergic vasorelaxation observed in portal hypertension is mediated largely by HSP-90.Lukas Moleda Lars Jurzik Matthias Froh Erwin Gbele Claus Hellerbrand Rainer H Straub Jürgen Schlmerich Reiner Wiest 2010World Journal of Gastroenterology2010,16,15:4
12Do viral infections protect from or enhance type 1 diabetes and how can we tell the difference?显示文摘Virus infections have been implicated in both initiation of and protection from autoimmune diseases,such as type 1 diabetes(T1D).In this review we intend to reflect on recent evidence how viruses might on the one hand be involved in the pathogenesis of T1D and on the other hand induce a state of protection from autoimmune-mediated damage.It is important to acknowledge that human individuals encounter more than just one virus infection in their lifetime.Therefore,it is important to integrate more than just one possible environmental triggering factor for autoimmune diseases to occur.Urs Christen Matthias G von Herrath 2011Cellular & Molecular Immunology2011,8,3:4
13Triggers of histologically suspected drug-induced colitis显示文摘BACKGROUND Drug toxicity is a common and even serious problem in the gastrointestinal tract that is thought to be caused by a broad spectrum of agents.Although withdrawal of the causative agent would cure the disease knowledge is scarce and mostly derives from case reports and series.AIM To investigate potential triggers of drug-induced colitis(DiC).METHODS We conducted a retrospective,observational case control study.Patients were assigned to DiC or one of two age-and gender-matched control groups(noninflammatory controls and inflammatory colitis of another cause)based on histopathological findings.Histopathology was reassessed in a subset of patients(28 DiC with atherosclerosis,DiC without atherosclerosis and ischaemic colitis each)for validation purposes.Medical history was collected from the electronic database and patient records.Statistical analysis included chi-squared test,t-test,logistic and multivariate regression models.RESULTS Drug-induced colitis was detected in 211 endoscopically sampled biopsy specimens of the colon mucosa(7%of all screened colonoscopic biopsy samples);a total of 633 patients were included equally matched throughout the three groups(291 males,mean age:62.1±16.1 years).In the univariate analysis,DiC was associated with diuretics,dihydropyridines,glycosides,ASS,platelet aggregation inhibitors,nonsteroidal anti-inflammatory drugs(NSAIDs),statins and fibrates,and with atherosclerosis,particularly coronary heart disease,and hyperlipoproteinaemia.Echocardiographic parameters did not show substantial differences.In the multivariate analysis only fibrates[odds ratio(OR)=9.1],NSAIDs(OR=6.7)and atherosclerosis(OR=2.1)proved to be associated with DiC.Both DiC reassessment groups presented milder inflammation than ischaemic colitis.The DiC patients with atherosclerosis exhibited histological features from both DiC without atherosclerosis and ischaemic colitis.CONCLUSION Several drugs indicated for the treatment of cardiovascular and related diseases are associated with DiC.Atherosclerosis and microcirculatory disturbances seem to play an important pathogenetic role.Thorsten Brechmann Katharina Günther Matthias Neid Wolff Schmiegel Andrea Tannapfel 2019World Journal of Gastroenterology2019,25,8:3
