| 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 | Pancreatic cancer: A review of clinical diagnosis, epidemiology, treatment and outcomes显示文摘This review aims to outline the most up-to-date knowledge of pancreatic adenocarcinoma risk, diagnostics, treatment and outcomes, while identifying gaps that aim to stimulate further research in this understudied malignancy. Pancreatic adenocarcinoma is a lethal condition with a rising incidence, predicted to become the second leading cause of cancer death in some regions. It often presents at an advanced stage, which contributes to poor five-year survival rates of 2%-9%, ranking firmly last amongst all cancer sites in terms of prognostic outcomes for patients. Better understanding of the risk factors and symptoms associated with this disease is essential to inform both health professionals and the general population of potential preventive and/or early detection measures. The identification of high-risk patients who could benefit from screening to detect pre-malignant conditions such as pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasms and mucinous cystic neoplasms is urgently required, however an acceptable screening test has yet to be identified. The management of pancreatic adenocarcinoma is evolving, with the introduction of new surgical techniques and medical therapies such as laparoscopic techniques and neo-adjuvant chemoradiotherapy, however this has only led to modest improvements in outcomes. The identification of novel biomarkers is desirable to move towards a precision medicine era, where pancreatic cancer therapy can be tailored to the individual patient, while unnecessary treatments that have negative consequences on quality of life could be prevented for others. Research efforts must also focus on the development of new agents and delivery systems. Overall, considerable progress is required to reduce the burden associated with pancreatic cancer. Recent, renewed efforts to fund large consortia and research into pancreatic adenocarcinoma are welcomed, but further streams will be necessary to facilitate the momentum needed to bring breakthroughs seen for other cancer sites. | Andrew McGuigan Paul Kelly Richard C Turkington Claire Jones Helen G Coleman R Stephen McCain | 2018 | World Journal of Gastroenterology2018,24,43: | 140 |

| 5 | 不同收获方式含水率对油菜收获物流损失的影响显示文摘收获物流损失是影响油菜生产成本的重要因素,以DMH145油菜品种为对象,在丹麦FOULUM农业研究中心试验研究了油菜籽粒含水率对油菜分段收获和联合收获中3种主要损失的影响,建立了含水率与3种主要损失及总损失之间的数学函数,另外秸秆含水率对秸秆收获物流损失的影响也进行了研究。结果表明:随着含水率的降低,脱粒损失和清选损失降低,但是过低的含水量会使割台损失增大。总损失与含水率之间存在CUBIC函数关系且关系显著;不同含水率情况下,分段收获和联合收获籽粒平均损失率分别为16.358%和18.771%,分段收获平均高出联合收获2.4%;在三大损失中割台损失最低值0.976%,平均低于脱粒损失和清选损失;秸秆含水率对秸秆收获物流损失影响不显著。 | 刘德军 赵秀荣 高连兴 Sφrensen C G | 2011 | 农业工程学报2011,27,10: | 46 |
| 6 | AGNP精神科治疗药物监测共识指南:2011显示文摘治疗药物监测(Therapeutic drug monitoring,TDM),如通过定量测定血清或血浆药物浓度指导用药剂量优化,已经成为对患者进行精神药物治疗的很有价值的工具。在患者用药依从性难以判断、药物耐受性不佳、治疗剂量下无效以及可能存在药代动力学药物-药物相互作用等情况下,测定药物浓度是很有用的。在精神科,有可能明显获益于TDM的主要患者群体包括儿童、孕妇、老年患者、智力障碍患者、涉及司法的患者、已知或怀疑携带药代动力学相关基因变异的患者,以及合并躯体疾病影响药代动力学的患者。然而,只有将TDM充分整合到临床治疗过程中去,才能发挥其优化药物治疗的潜在优势。为了促进TDM的合理应用,神经精神药理学与药物精神病学协会(Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie,AGNP)的TDM专家组在2004年发表了精神药物治疗药物监测指南。之后,随着知识不断更新,又有许多可能需要进行TDM的新药上市。因此,本次更新将神经精神药物的种类扩展到了128种,并将其TDM必要性划分为从'强烈推荐'到'可能有用'的四个等级。经过大量细致且全面的文献检索与分门别类的汇总整理,将基于循证医学理念的'治疗参考浓度范围'和'剂量相关参考浓度范围'呈现给大家。本共识指南引入了'实验室警戒浓度'的新概念,即实验室需要马上告知治疗医生的药物浓度上限。本共识指南还给出了诸如药物作为细胞色素P450酶的底物和抑制剂的性质,代谢物与母药浓度比值的常见范围,以及与结果解释相关的内容,还提供了何时将TDM与遗传药理学检测相结合的建议。遵循本指南,有助于改善许多患者精神药物治疗的效果,特别是那些存在药代动力学异常的患者。TDM是一门交叉学科,有时针对看起来不一致的数据,需要多学科坦诚地讨论,只有这样,患者才能从这种合作中获益。 | Hiemke C Baumann P Bergemann N Conca A Dietmaier O Egberts K Fric M Gerlach M Greiner C Gründer G Haen E Havemann-Reinecke U Jaquenoud Sirot E Kirchherr H Laux G Lutz UC Messer T Müller MJ Pfuhlmann B Rambeck B Riederer P Schoppek B Stingl J Uhr M Ulrich S Waschgler R Zernig G 李文标(译) 果伟(译) 阮灿军(译) 贺静(译) 汤宜朗(审校) 王传跃(审校) | 2016 | 实用药物与临床2016,19,10: | 37 |
| 7 | 利用AFLP进行“甘蔗属复合体”系统演化和亲缘关系研究显示文摘采用AFLP分子标记技术,对“甘蔗属复合体”中4个属16个种的6 9份来自中国和澳大利亚的甘蔗种质资源材料进行系统演化和亲缘关系分析。2对AFLP引物共检测到173个标记,其中172个为多态标记,多态率达99 4 % ;通过计算Jaccard相似性系数,用UPGMA和PCA法构建了分子系统树和效应图。结果表明:(1)属间亲缘关系中,甘蔗属与芒属较近,与河八王属和蔗茅属较远,而河八王属与蔗茅属较近;(2 )甘蔗属内,细茎野生种与其他种关系较远,其中,栽培品种与热带种关系较近,中国种和印度种关系较近,而大茎野生种自聚为一族,与上述4种分离;(3)蔗茅属内,除蔗茅种和滇蔗茅种外,无论是中国斑茅(云南、海南)还是印度尼西亚斑茅,都与蔗茅属其他种聚在一起,其中与E procerus的关系最近,与E bengalense和E sarpet种次之;由斑茅与这3个种构成的群体与由E elephantinus和E ravennae构成的群体相对分离,形成了明显的2个组群。再次表明斑茅应列入蔗茅属,建议我国甘蔗学者采纳国外分类命名(E arundinaceus) ,以能更好地开展斑茅的研究和杂交育种利用并与国际接轨;(4)蔗茅和滇蔗茅均没有聚类到蔗茅属类群中,而分别独立位于系统树2大枝系上。蔗茅与甘蔗属亲缘关系较近,与芒属亲缘关系次之,与蔗茅属和河八王属关系较远;滇蔗茅与河八王属亲缘关系? | 蔡青 范源洪 Aitken K Piperidis G McIntyre C L Jackson P | 2005 | 作物学报2005,31,5: | 33 |
| 8 | Diabetic neuropathic pain:Physiopathology and treatment显示文摘Diabetic neuropathy is a common complication of both type 1 and type 2 diabetes,which affects over 90% of the diabetic patients.Although pain is one of the main symptoms of diabetic neuropathy,its pathophysiological mechanisms are not yet fully known.It is widely accepted that the toxic effects of hyperglycemia play an important role in the development of this complication,but several other hypotheses have been postulated.The management of diabetic neuropathic pain consists basically in excluding other causes of painful peripheral neuropathy,improving glycemic control as a prophylactic therapy and using medications to alleviate pain.First line drugs for pain relief include anticonvulsants,such as pregabalin and gabapentin and antidepressants,especial y those that act to inhibit the reuptake of serotonin and noradrenaline.In addition,there is experimental and clinical evidence that opioids can be helpful in pain control,mainly if associated with first line drugs.Other agents,including for topical application,such as capsaicin cream and lidocaine patches,have also been proposed to be useful as adjuvants in the control of diabetic neuropathic pain,but the clinical evidence is insufficient to support their use.In conclusion,a better understanding of the mechanisms underlying diabetic neuropathic pain will contribute to the search of new therapies,but also to the improvement of the guidelines to optimize pain control with the drugs currently available. | Anne K Schreiber Carina FM Nones Renata C Reis Juliana G Chichorro Joice M Cunha | 2015 | World Journal of Diabetes2015,6,3: | 34 |
| 9 | 最新AD研究用诊断标准:IWG-2标准显示文摘在过去的8年中,国际工作组织(IWG)和美国国立老化研究院-阿尔茨海默协会(NIA-AA)建立了阿尔茨海默病(AD)诊断标准,它能更好地定义AD的临床表型,整合了生物标记物于诊断流程中,并覆盖了疾病的全程。本意见书充分地权衡了IWG标准的优缺点,建议改进诊断框架。依据这些改进,AD的诊断变得简单,只要有恰当的AD临床表型(典型或不典型)和与AD的病理相一致的病理生理学生物标志物出现。我们认为疾病的下游的定位性生物标志,如容积性磁共振成像(MRI)和氟脱氧葡萄糖-正电子发射型计算机断层成像(FDG-PET)等,适合更好地测量和监测疾病过程。本文还详述了非典型性AD、混合性AD和AD临床前期的特异诊断标准。 | 陈刚 曹雯炜 俞羚 糜建华 Dubois B Feldman HH Jacova C Hampel H Molinuevo JL Blennow K DeK osky ST Gauthier S Selkoe D Bateman R Cappa S Crutch S Engelborghs S Frisoni GB Fox NC Galasko D Habert MO Jicha GA Nordberg A Pasquier F Rabinovici G Robert P Rowe C Salloway S Sarazin M Epelbaum S de Souza LC Vellas B Visser PJ Schneider L Stern Y Scheltens P Cummings JL | 2014 | 神经病学与神经康复学杂志2014,11,3: | 31 |
| 10 | Use of probiotics for prevention of radiation-induced diarrhea显示文摘AIM: To investigate the efficacy of a high-potency probiotic preparation on prevention of radiation-induced diarrhea in cancer patients. METHODS: This was a double-blind, placebo-controlled trial. Four hundred and ninety patients who underwent adjuvant postoperative radiation therapy after surgery for sigmoid, rectal, or cervical cancer were assigned to either the high-potency probiotic preparation VSL#3 (one sachet t.i.d.,) or placebo starting from the first day of radiation therapy. Efficacy endpoints were incidence and severity of radiation-induced diarrhea, daily number of bowel movements, and the time from the start of the study to the use of loperamide as rescue medication. RESULTS: More placebo patients had radiation-induced diarrhea than VSL#3 patients (124 of 239 patients, 51.8%, and 77 of 243 patients, 31.6%; P < 0.001) and more patients given placebo suffered grade 3 or 4 diarrhea compared with VSL#3 recipients (55.4% and 1.4%, P < 0.001). Daily bowel movements were 14.7 ± 6 and 5.1 ± 3 among placebo and VSL#3 recipients (P < 0.05), and the mean time to the use of loperamide was 86 ± 6 h for placebo patients and 122 ± 8 h for VSL#3 patients (P < 0.001). CONCLUSION: Probiotic lactic acid-producing bacteria are an easy, safe, and feasible approach to protect cancer patients against the risk of radiation-induced diarrhea. | P Delia G Sansotta V Donato P Frosina G Messina C De Renzis G Famularo | 2007 | World Journal of Gastroenterology2007,13,6: | 29 |
| 11 | Laparoscopic and robot-assisted laparoscopic digestivesurgery:Present and future directions显示文摘Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen's fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated. | Juan C Rodríguez-Sanjuán Marcos Gómez-Ruiz Soledad Trugeda-Carrera Carlos Manuel-Palazuelos Antonio López-Useros Manuel Gómez-Fleitas | 2016 | World Journal of Gastroenterology2016,22,6: | 27 |
| 12 | Modern management of rectal cancer: A 2006 update显示文摘The goal of this review is to outline some of the important surgical issues surrounding the management of patients with early (T1/T2 and NO), as well as locally advanced (T3/T4 and/or N1) rectal cancer. Surgery for rectal cancer continues to develop towards the ultimate goals of improved local control and overall survival, maintaining quality of life, and preserving sphincter, genitourinary, and sexual function. Information concerning the depth of tumor penetration through the rectal wall, lymph node involvement, and presence of distant metastatic disease is of crucial importance when planning a curative rectal cancer resection. Preoperative staging is used to determine the indication for neoadjuvant therapy as well as the indication for local excision versus radical cancer resection. Local excision is likely to be curative in most patients with a primary tumor which is limited to the submucosa (T1N0M0), without high-risk features and in the absence of metastatic disease. In appropriate patients, minimally invasive procedures, such as local excision, TEM, and laparoscopic resection allow for improved patient comfort, shorter hospital stays, and earlier return to preoperative activity level. Once the tumor invades the muscularis propria (T2), radical rectal resection in acceptable operative candidates is recommended. In patients with transmural and/or node positive disease (T3/T4 and/or N1) with no distant metastases, preoperative chemoradiation followed by radical resection according to the principles of TME has become widely accepted. During the planning and conduct of a radical operation for a locally advanced rectal cancer, a number of surgical management issues are considered, including: (1) total mesorectal excision (TME); (2) autonomic nerve preservation (ANP); (3) circumferential resection margin (CRM); (4) distal resection margin; (5) sphincter preservation and options for restoration of bowel continuity; (6) laparoscopic approaches; and (7) postoperative quality of life. | Glen C Balch Alex De Meo Jose G Guillem | 2006 | World Journal of Gastroenterology2006,12,20: | 26 |
| 13 | 光复散射对消光法粒径测量的影响:复散射模型与数值模拟显示文摘复散射效应在光散射颗粒测量中不仅重要 ,且尚未得到很好解决。采用蒙特卡罗方法 ,对不同的光波长 ,颗粒浓度以及收接器条件下的光复散射进行了数值模拟 ,数值算法程序经与四通量模型进行对比验证 ,数值结果与单散射条件的郎伯比尔模型进行比较 ,进而讨论了复散射效应对消光法颗粒粒径测量影响。表明复散射对消光法颗粒测量的影响不仅取决于颗粒系自身的浓度 ,而且接收器的几何尺寸和接收位置起着非常重要的作用 ,减小颗粒介质层厚度和减小光接收器接收面积 ,增大接收距离以及减小接收角都能减小复散射效应对消光法粒径测量的影响。 | 苏明旭 任宽芳 Grehan G 蔡小舒 Rozé C Girasole T | 2004 | 光学学报2004,24,5: | 25 |
| 14 | Clinical and cost impact of intravenous proton pump inhibitor use in non-ICU patients显示文摘AIM:To assess the appropriateness of the indication and route of administration of proton-pump-inhibitors (PPIs) and their associated cost impact. METHODS:Data collection was performed prospec-tively during a 6-mo period on 340 patients who re-ceived omeprazole intravenously during their hospital stay in non-intensive care floors. Updated guidelines were used to assess the appropriateness of the indication and route of administration. RESULTS:Complete data collection was available for 286 patients which were used to assess intravenous (IV) PPIs utilization. Around 88% of patients were receiving PPIs for claimed stress ulcer prophylaxis (SUP) indication; of which,only 17% met the guideline criteria for SUP indication,14% met the criteria for non-steroidal-anti-inflammatory drugs-induced ulcer prophylaxis,while the remaining 69% were identifi ed as having an unjustified indication for PPI use. Theinitiation of IV PPIs was appropriate in 55% of pa-tients. Half of these patients were candidates for switching to the oral dosage form during their hos-pitalization,while only 36.7% of these patients were actually switched. The inappropriate initiation of PPIs via the IV route was more likely to take place on the medical floor than the surgical floor (53% vs 36%,P = 0.003). The cost analysis associated with the appro-priateness of the indication for PPI use as well as the route of administration of PPI revealed a possible saving of up to $17 732.5 and $14 571,respectively. CONCLUSION:This study highlights the over-utili-zation of IV PPIs in non-intensive care unit patients. Restriction of IV PPI use for justified indications and route of administration is recommended. | Soumana C Nasser Jeanette G Nassif Hani I Dimassi | 2010 | World Journal of Gastroenterology2010,16,8: | 23 |
| 15 | 沂蒙山林区不同植物群落下土壤颗粒分形与孔隙结构特征显示文摘为探索人为活动干扰下植物群落变化对土壤物理结构特征的影响,运用土壤分形学和水文学原理与方法研究沂蒙山林区7种植物群落下的土壤颗粒组成、分形维数、土壤孔隙度及其相关性。结果表明:在长期农业耕作等人为干扰下,玉米作物、板栗经济林和灌草丛群落下的土壤颗粒呈粗粒化特征,分形维数显著降低,土壤总孔隙度和毛管孔隙度下降,非毛管孔隙度增加,土壤物理结构呈现退化状态;而处于长期封禁保护下的森林群落,土壤颗粒分形维数较大,粉黏粒等细粒物质的含量较高,孔隙结构状况较好。研究区土壤颗粒组成具有石质山地典型的粗骨土结构特征,森林群落能显著增加土壤中粉黏粒等细粒物质的含量和对土壤空隙的填充能力,是其改善土壤物理结构的分形学机制。土壤颗粒分形维数与土壤粉黏粒含量、总孔隙度和毛管孔隙度之间存在明显的线性正相关,而与土壤砂粒含量和非毛管孔隙度具有线性负相关关系,它能较好表征植物群落变化对土壤颗粒组成和孔隙状况的影响,因而可作为评价土壤物理结构质量的一项综合性指标。 | 刘霞 姚孝友 张光灿 胡续礼 Heathman G C | 2011 | 林业科学2011,47,8: | 22 |

| 17 | Contribution of oxidative stress to pulmonary arterial hypertension显示文摘Recent data implicate oxidative stress as a mediator of pulmonary hypertension (PH) and of the associated pathological changes to the pulmonary vasculature and right ventricle (RV). Increases in reactive oxygen species (ROS), altered redox state, and elevated oxidant stress have been demonstrated in the lungs and RV of several animal models of PH, including chronic hypoxia, monocrotaline toxicity, caveolin-1 knock-out mouse, and the transgenic Ren2 rat which overexpresses the mouse renin gene. Generation of ROS in these models is derived mostly from the activities of the nicotinamide adenine dinucleotide phosphate oxidases, xanthine oxidase, and uncoupled endothelial nitric oxide synthase. As disease progresses circulating monocytes and bone marrow-derived monocytic progenitor cells are attracted to and accumulate in the pulmonary vasculature. Once established, these inflammatory cells generate ROS and secrete mitogenic and fibrogenic cytokines that induce cell proliferation and fibrosis in the vascular wall resulting in progressive vascular remodeling. Deficiencies in antioxidant enzymes also contribute to pulmonary hypertensive states. Current therapies were developed to improve endothelial function, reduce pulmonary artery pressure, and slow the progression of vascular remodeling in the pulmonary vasculature by targeting deficiencies in either NO (PDE-type 5 inhibition) or PGI 2 (prostacyclin analogs), or excessive synthesis of ET-1 (ET receptor blockers) with the intent to improve patient clinical status and survival. New therapies may slow disease progression to some extent, but long term management has not been achieved and mortality is still high. Although little is known concerning the effects of current pulmonary arterial hypertension treatments on RV structure and function, interest in this area is increasing. Development of therapeutic strategies that simultaneously target pathology in the pulmonary vasculature and RV may be beneficial in reducing mortality associated with RV failure. | Vincent G DeMarco Adam T Whaley-Connell James R Sowers Javad Habibi Kevin C Dellsperger | 2010 | World Journal of Cardiology2010,2,10: | 21 |
| 18 | Reduction of Cancer Risk With an Oral Supplement of Selenium显示文摘The hypothesis that a dietary Supplement of selenium (Se) may reduce cancer risk was tested experimetally in humans. Patients with histories of basal/squarnous cell carcinomas of the skin were assigned randomly in double-blind fashion to dally oral supplements of either Seenriched yeast (200 μg Se/day), or a low-Se yeast placebo. A total of 1312 patients recruited in 1983-1990 were followed with regular dermatologic examinations through 1993 for a total of 8269 person-years of observation. Skin cancer diagnoses were confirmed histologically.Plasma Se concentration was determined at 6-12 months intervals. All deaths and patient-reported illnesses were recorded; reported cancers were confirmed and documented by consultation with the patient medical care providers. The results indicate that Se did not significantly affect the primary endpoints: incidences of recurrent basal/squarnous cell carcinomas of the skin. However, Setreatment was associated with reductions in several secondary endpoints:total mortality, mortality from all cancers combined, as well as the incidence of all cancers combined, lung cancer, colorectal cancer and prostate cancer. The consistencies of these associations over time, between study clinics and for the leading cancer sltes strongly suggests benefits of Se-supplementation for this cohort of patients, supporting the hypopthesis that supplemental Se can reduce cancer risk. Although Se did no shown protective effects against nonmelanoma skin cancers, the suggested reductions in risks to other frequent cancers demand further evaluation in well controlled cliflical intervention | G·F·COMBSJR L·C·CLARK 等 | 1997 | Biomedical and Environmental Sciences1997,10,2: | 21 |
