1美国临床肿瘤学会IV期非小细胞肺癌化疗的临床实践指南更新显示文摘本文旨在为IV期非小细胞肺癌患者的治疗提供更新版推荐。本文资料检索源自2002年以来公布的相关随机试验文献。此指南范围限于化疗与生物治疗。更新委员会对这些文献进行了总结并提供了推荐更新。162篇文献符合标准被纳入参考。本推荐基于可改善总生存期的治疗方法。仅改善无进展生存期的治疗方法推动了对毒性及生存质量的监测。对于体力状态评分为0分或1分患者的一线治疗,可推荐以铂类为基础的细胞毒性药物的两药联用。对铂类治疗有禁忌的患者,可采用非铂类细胞毒性两药联合。对于体力状态评分为2分的患者,单一细胞毒性药物即可。对于疾病进展或经过4个周期的治疗仍对治疗无反应的患者,应停止一线细胞毒性化疗。即使在6个周期后患者对治疗仍有反应,亦应停止两药细胞毒性化疗。对于伴有明确的表皮生长因子受体(epidermal growth factor receptor,EGFR)突变的患者,可推荐一线采用吉非替尼治疗;对于EGFR突变为阴性或不明确的患者,细胞毒性化疗更佳。除具有特定临床特征的患者外,可推荐贝伐单抗与卡铂-紫杉醇联用。对于通过免疫组化证实EGFR阳性的肿瘤患者,可推荐西妥昔单抗与顺铂-长春瑞滨联用。多西紫杉醇、厄洛替尼、吉非替尼或培美曲塞被推荐作为二线治疗。对于未曾接受过厄洛替尼或吉非替尼治疗的患者,可推荐厄洛替尼作为三线治疗。现有数据不足以推荐常规三线采用细胞毒性药物。已有的证据也不足以推荐常规应用分子标记物选择化疗。Christopher G.

2Degradation of organic pollutants by a Co_3O_4 -graphite composite electrode in an electro-Fenton-like system显示文摘A novel composite electrode was constructed by pressing together Co3O4 and graphite and it was used as the cathode in an electro-Fenton-like (EFL) system. The poor electron transport characteristic of Co3O4 was overcome by incorporating graphite. In situ electro-catalytic generation of hydroxyl radicals (·OH) occurred at high current efficiencies from pH 2-10, extending the traditional Fenton reaction pH range. Cyclic voltammetry and AC impedance spectrometry were used to characterize the composite electrode. The ability of the EFL system to degrade organic compounds was investigated using sulforhodamine B (SRB) and 2,4-dichlorophenol (2,4-DCP) as probes. Decoloration of SRB (1.0×10-5 mol/L) was complete (100%) in 150 min and SRB was effectively degraded from pH 2-10. The decomposition of SRB was studied using Fourier transform infrared spectroscopy (FT-IR) and total organic carbon (TOC) analysis and results indicated that the final degradation products were carbon dioxide, carboxylic acids and amines. The EFL system also decomposed 2,4-DCP and the degradation was 98.6% in 240 min. Electro-catalytic degradation of SRB occurs by a ·OH mechanism. After 5 times reused, the degradation rate of SRB did not significantly slow down. The electrode shows excellent potential for use in advanced oxidation processes (AOPs) used to treat persistent organic pollutants (POPs) in wastewater.LIU Shuan GU Yan WANG ShuLian ZHANG Yu FANG YanFen JOHNSON David M HUANG YingPing 2013Chinese Science Bulletin2013,58,19:18
3冠状动脉内影像学临床应用专家共识(第一部分):对冠状动脉介入治疗的指导与优化显示文摘欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。Lorenz Raber Gary S Mintz Konstantinos C Koskinas Thomas W Johnson Niels R Holm Yoshinubo Onuma Maria D Radu Michael Joner Bo Yu Haibo Jia Nicolas Meneveau Jose M.de la Torre Hemandez Javier Escaned Jonathan Hill Francesco Prati Antonio Colombo Carlo di Mario Evelyn Regar Davide Capodanno William Wijns Robert A Byme Giulio Guagliumi 2019中华心血管病杂志2019,47,1:17
4Endoscopy and polyps-diagnostic and therapeutic advances in management显示文摘Despite multiple efforts aimed at early detection through screening, colon cancer remains the third leading cause of cancer-related deaths in the United States, with an estimated 51000 deaths during 2013 alone. The goal remains to identify and remove benign neoplastic polyps prior to becoming invasive cancers. Polypoid lesions of the colon vary widely from hyperplastic, hamartomatous and inflammatory to neoplastic adenomatous growths. Although these lesions are all benign, they are common, with up to one-quarter of patients over 60 years old will develop pre-malignant adenomatous polyps. Colonoscopy is the most effective screening tool to detect polyps and colon cancer, although several studies have demonstrated missed polyp rates from 6%-29%, largely due to variations in polyp size. This number can be as high as 40%, even with advanced (> 1 cm) adenomas. Other factors including sub-optimal bowel preparation, experience of the endoscopist, and patient anatomical variations all affect the detection rate. Additional challenges in decision-making exist when dealing with more advanced, and typically larger, polyps that have traditionally required formal resection. In this brief review, we will explore the recent advances in polyp detection and therapeutic options.Scott R Steele Eric K Johnson Bradley Champagne Brad Davis Sang Lee David Rivadeneira Howard Ross Dana A Hayden Justin A Maykel 2013World Journal of Gastroenterology2013,19,27:16

6三峡库区香溪河库湾土壤多环芳烃时空分布特征及风险评价显示文摘为了全面评价三峡库区土壤多环芳烃(polycyclic aromatic hydrocarbons,PAHs)环境行为,以香溪河库湾不同淹没类型土壤[消落带上缘(> 175 m)、消落带(145~175 m)和沉积物(<145 m)]为研究对象,通过高效液相色谱检测方法,分析3个区域土壤16种美国环保署优先控制的PAHs含量.结果表明,香溪河库湾土壤PAHs总量表现为消落带上缘>消落带>沉积物,沉积物PAHs以3环和4环为主,而消落带及其上缘土壤PAHs以4环和5环为主,其中消落带土壤PAHs变异系数相对最高,与其它两个区域PAHs组成之间的相关性相对较弱.各区域土壤PAHs分布呈现季节差异,夏季和冬季土壤PAHs含量相对较高,主要与库区各季节居民能源消费类型有关;空间分布特征表现为,沉积物PAHs空间分布整体较为均匀,而消落带及其上缘土壤PAHs在峡口镇和长江入江口处PAHs含量相对较高,主要与空间水平上各样点频繁的人类活动有关.PAHs异构体比值法分析表明,香溪河库湾各区域土壤PAHs来源具有季节性差异,化石燃料和生物质的不完全燃烧是消落带土壤PAHs的主要来源;终身致癌风险评价模型分析表明,土壤PAHs通过误食和皮肤接触暴露途径对人体健康产生潜在致癌风险,并且消落带上缘土壤PAHs致癌风险相对较大.研究结果扩展了对香溪河库湾土壤PAHs环境行为的认识,为三峡库区香溪河库湾土壤PAHs污染防治提供有益参考.黄应平 金蕾 朱灿 李锟 谢平 David Johnson 刘慧刚 席颖 2021环境科学2021,42,8:9
7Role of microbial dysbiosis in the pathogenesis of esophageal mucosal disease:A paradigm shift from acid to bacteria?显示文摘Genomic sequencing,bioinformatics,and initial speciation(e.g.,relative abundance)of the commensal microbiome have revolutionized the way we think about the“human”body in health and disease.The interactions between the gut bacteria and the immune system of the host play a key role in the pathogenesis of gastrointestinal diseases,including those impacting the esophagus.Although relatively stable,there are a number of factors that may disrupt the delicate balance between the luminal esophageal microbiome(EM)and the host.These changes are thought to be a product of age,diet,antibiotic and other medication use,oral hygiene,smoking,and/or expression of antibiotic products(bacteriocins)by other flora.These effects may lead to persistent dysbiosis which in turn increases the risk of local inflammation,systemic inflammation,and ultimately disease progression.Research has suggested that the etiology of gastroesophageal reflux disease-related esophagitis includes a cytokine-mediated inflammatory component and is,therefore,not merely the result of esophageal mucosal exposure to corrosives(i.e.,acid).Emerging evidence also suggests that the EM plays a major role in the pathogenesis of disease by inciting an immunogenic response which ultimately propagates the inflammatory cascade.Here,we discuss the potential role for manipulating the EM as a therapeutic option for treating the root cause of various esophageal disease rather than just providing symptomatic relief(i.e.,acid suppression).Steve M D'Souza Kevin Houston Lauren Keenan Byung Soo Yoo Parth J Parekh David A Johnson 2021World Journal of Gastroenterology2021,27,18:8

11Clinical update for the diagnosis and treatment of Clostridium difficile infection显示文摘Clostridium difficile infection(CDI)presents a rapidly evolving challenge in the battle against hospitalacquired infections.Recent advances in CDI diagnosis and management include rapid changes in diagnostic approach with the introduction of newer tests,such as detection of glutamate dehydrogenase in stool and polymerase chain reaction to detect the gene for toxin production,which will soon revolutionize the diagnostic approach to CDI.New medications and multiple medical society guidelines have introduced changing concepts in the definitions of severity of CDI and the choice of therapeutic agents,while rapid expansion of data on the efficacy of fecal microbiota transplantation heralds a revolutionary change in the management of patients suffering multiple relapses of CDI.Through a comprehensive review of current medical literature,this article aims to offer an intensive review of the current state of CDI diagnosis,discuss the strengths and limitations of available laboratory tests,compare both current and future treatments options and offer recommendations for best practice strategies.Edward C Oldfield Ⅳ Edward C Oldfield Ⅲ David A Johnson 2014World Journal of Gastrointestinal Pharmacology and Therapeutics2014,5,1:6
