| 2 | 2018加拿大心境障碍与焦虑障碍治疗协作组/国际双相障碍学会指南:双相障碍的管理显示文摘加拿大心境障碍与焦虑障碍治疗协作组(Canadian Network for Mood and Anxiety Treatments,CANMAT)曾于2005年发布了第1版双相障碍管理指南,并分别于2007、2009和2013年对该指南进行了更新,其中最近的2次更新是与国际双相障碍学会(International Society for Bipolar Disorders,ISBD)合作完成。2018版CANMAT/ISBD双相障碍治疗指南(以下简称指南)反映了自2005年首版指南发表以来本领域取得的重大进展,包括疾病诊断与疾病管理的更新以及药物治疗与心理治疗的近期研究进展。这些前沿进展中综合考虑了循证证据的级别,并基于治疗疗效、临床实践经验、安全性、耐受性和药物导致的转相风险等,对一线、二线及三线治疗方案进行了简明而清晰的推荐。本指南中新增内容涵盖了双相Ⅰ型障碍(BD-Ⅰ)的躁狂发作急性期、抑郁发作急性期和双相障碍维持期的一线及二线治疗推荐等级划分。这种对治疗推荐等级的划分综合考虑了治疗方法对双相障碍不同时相的影响,将进一步帮助临床医生做出基于循证证据的治疗决策。锂盐、喹硫平、双丙戊酸盐、阿塞那平、阿立哌唑、帕利哌酮、利培酮和卡利拉嗪单药或联合使用被推荐为躁狂发作急性期的一线治疗选择。BD-Ⅰ抑郁期的一线治疗选择包括喹硫平、鲁拉西酮、锂盐、拉莫三嗪单药,鲁拉西酮联合锂盐或双丙戊酸盐或拉莫三嗪辅助治疗。尽管急性期治疗有效的药物通常应继续用于BD-Ⅰ的维持期治疗,但也存在一些特殊情况(例如抗抑郁药)。现有数据表明,锂盐、喹硫平、双丙戊酸盐、拉莫三嗪、阿塞那平和阿立哌唑单药或联合治疗应被视为维持治疗的初始或更换治疗方案时的一线选择。除了探讨BD-Ⅰ的相关问题外,本指南中还对双相Ⅱ型障碍(BD-Ⅱ)的临床管理进行了系统回顾并给予治疗推荐,同时针对特殊人群也有相关推荐,如处于各个生殖周期的女性、儿童、青少年和老年人。此外,本指南中还讨论了特定精神疾病及共病(如物质滥用、焦虑障碍和代谢性疾病)的影响。最后,本指南中概述了安全性和药物监测的相关问题。CANMAT/ISBD工作组希望本指南能够成为全球临床医生的实用工具。 | Lakshmi N Yatham Sidney H Kennedy Sagar V Parikh Ayal Sehaffer David J Bond Benicio N Frey Verinder Sharma Benjamin I Goldstein Soham Rej Serge Beaulieu Martin Alda Glenda MaeQueen Roumen V Milev Arun Ravindran Claire O'Donovan Diane Mclntosh Raymond W Lam Gustavo Vazquez Flavio Kapczinski Roger S Melntyre Jan Kozicky Shigenobu Kanba Beny Lafer Trisha Suppes Joseph R Calabrese Eduard Vieta Gin Malhi Robert M Post Michael Berk 胡晨(译) 王刚(译) | 2019 | 中华精神科杂志2019,52,1: | 25 |
| 3 | WONCA研究论文摘要汇编——慢性阻塞性肺疾病对亚太地区的影响:基于亚洲人群的EPIC调查显示文摘背景慢性阻塞性肺疾病(COPD)是一种慢性、进行性呼吸减弱的临床病症,主要临床表现为不完全可逆性气流受限。在亚太地区,关于COPD患病率的研究较多,但关于COPD影响的研究较少,本研究旨在对COPD的现患病率及其对亚太地区的影响进行综合阐述。方法 2012年2月1日—5月16日,在亚太地区的9个区域进行人群调查。共有112 300个家庭接受调查,从中抽取符合本研究纳入标准(≥40岁;确诊为COPD、慢性支气管炎或肺气肿,或伴有慢性支气管炎症状)的居民69 279例,其中确诊为COPD的居民为4 289例。采用结构式调查问卷,通过面对面采访或电话随访的形式收集居民的相关资料,最终纳入患者1 841例。结果估算COPD总患病率为6.2%,其中19.1%为重症。调查前的12个月内,近一半患者(46.0%)的病情加重,其中19.0%的患者因病情加重而入院治疗。关于COPD对工作的影响,23.0%的患者表示无法工作,42.0%的患者认为该病限制了工作或活动能力。20.0%服用处方药的患者不知晓自身服用药物的名称;44.0%的患者在调查前12个月内服用过常见口服皮质类固醇处方,而吸入器的使用率(25.0%)较低。仅有37.0%的患者进行了肺功能检查,但89.0%接受检测的患者不知晓检查结果。结论亚太地区的COPD患病率较高,因患病带来的社会经济负担较大。COPD管理能力提升空间较大,患者和医生的疾病相关教育有待加强。 | Lim1 S Chi-Leung Lam D M AR | 2015 | 中国全科医学2015,18,28: | 20 |
| 4 | 香港地区一次光化学污染过程的特征分析显示文摘对2000年3月28-31日发生在香港地区的一次光化学污染过程进行了分析。在这次过程中,O3、NO2、CO、RSP、SO2的最大浓度分别达到175.2μg/m3,333.5μg/m3,5405μg/m3,349.3μg/m3,132.8μg/m3,污染持续时间三天,影响范围覆盖香港全境。利用同步的气象资料和大气污染监测数据,进行了浓度变化分析、气象条件分析、局地光化学机制分析和输送机制分析。结果揭示了这次污染过程的基本特征,并指出造成这次大气污染的可能原因:晴天高温、低湿的气象条件和局地污染物的排放对此次光化学烟雾的形成有重要作用;外地污染物的输送对污染形成也有一定贡献。香港地区所处的地理位置、城市布局和交通状况有利于光化学污染的形成。 | 谢旻 王体健 高丽洁 LAM K S | 2004 | 热带气象学报2004,20,4: | 17 |
| 5 | 微创入路在脊柱手术中的应用显示文摘微创入路脊柱手术(MASS)是在经典微创脊柱手术(MISS)基础上发展而来的新的微创脊柱外科技术。MASS通过应用一些特殊设备或器械,经微创手术入路在直视下完成脊柱手术,减少手术入路对周围组织的损伤,同时又能达到传统开放手术同样的手术效果。MASS有效结合了MISS与开放手术的优势,减少了传统开放手术和MISS手术的并发症,具有手术组织创伤小、学习曲线相对MISS缩短、疗效确切、术后恢复快、医疗效价比高等优点,临床应用日益广泛。 | 宁尚龙 徐宝山 夏群 Khai S Lam | 2008 | 上海交通大学学报(医学版)2008,28,12: | 8 |
| 6 | Elevated basal intestinal mucosal cytokine levels in asymptomatic first-degree relatives of patients with Crohn's disease显示文摘AIM To determine levels of cytokines incolonic mucosa of asymptomatic first degreerelatives of Crohn’s disease patients.METHODS Cytokines(Interleukin(IL)1-Beta,IL-2,IL-5 and IL-8)were measured using ELISAin biopsy samples of normal looking colonicmucosa of first degree relatives of Crohn’sdisease patients(n = 9)and from normalcontrols(n = 10)with no family history ofCrohn’s disease.RESULTS Asymptomatic first degree relativesof patients with Crohn’s disease had significantlyhigher levels of basal intestinal mucosalcytokines(IL-2,IL-5 and IL-8)than normalcontrols.Whether these increased cytokinelevels serve as phenotypic markers for a geneticpredisposition to developing Crohns diseaselater on,or whether they indicate early(pre-clinical)damage has yet to be further defined.CONCLUSION Asymptomatic first degreerelatives of Crohn’s disease patients have higherlevels of cytokines in their normal-lookingintestinal mucosa compared to normal controls,This supports the hypothesis that increasedcytokines may be a cause or an early event inthe inflammatory cascade of Crohns disease andare not merely a result of the inflammatoryprocess. | Indaram AVK Nandi S Weissman S Lam S Bailey B Blumstein M Greenberg R Bank S | 2000 | World Journal of Gastroenterology2000,6,1: | 8 |

| 9 | Activation of human fibroblast-like synoviocytes by uric acid crystals in rheumatoid arthritis显示文摘Hyperuricemia-mediated uric acid crystal formation may cause joint inflammation and provoke the destruction of joints through the activation of inflammasome-mediated innate immune responses.However,the immunopathological effects and underlying intracellular regulatory mechanisms of uric acid crystal-mediated activation of fibroblast-like synoviocytes(FLS)in rheumatoid arthritis(RA)have not been elucidated.Therefore,we investigated the in vitro effects of monosodium urate crystals,alone or in combination with the inflammatory cytokines tumor-necrosis factor(TNF)-a or interleukin(IL)-1b,on the activation of human FLS from RA patients and normal control subjects and the underlying intracellular signaling mechanisms of treatment with these crystals.Monosodium urate crystals were able to significantly increase the release of the inflammatory cytokine IL-6,the chemokine CXCL8 and the matrix metalloproteinase(MMP)-1 from both normal and RA-FLS(all P,0.05).Moreover,the additive or synergistic effect on the release of IL-6,CXCL8 and MMP-1 from both normal and RA-FLS was observed following the combined treatment with monosodium urate crystals and TNF-a or IL-1b.Further experiments showed that the release of the measured inflammatory cytokine,chemokine and MMP-1 stimulated by monosodium urate crystals were differentially regulated by the intracellular activation of extracellular signal-regulated kinase and c-Jun N-terminal kinase pathways but not the p38 mitogen-activated protein kinase pathway.Our results therefore provide a new insight into the uric acid crystal-activated immunopathological mechanisms mediated by distinct intracellular signal transduction pathways leading to joint inflammation in RA. | Da P Chen Chun K Wong Lai S Tam Edmund K Li Christopher WK Lam | 2011 | Cellular & Molecular Immunology2011,8,6: | 5 |
| 10 | Phosphine oxide-functionalized polyfluorene derivatives:Synthesis,photophysics,electrochemical properties,and electroluminescence performance显示文摘A series of phosphine oxide-functionalized polyfluorene derivatives,PFH-PO-40-1 (P1),PFH-PO-20-1 (P2),PFH-PO-10-1 (P3),and PFH-PO-1-1 (P4),were prepared via a palladium-mediated Suzuki cross-coupling reaction.The structures and purities of all polymers were fully characterized by 1H and 13C NMR,UV-vis and photoluminescent spectroscopy,gel permeation chromatography,and TGA/DSC.Their emission features showed single broad peaks at about 445 nm in film,compared with those in dilute solutions,which might be caused by some degree of aggregation in the excited states of the backbones.The best electroluminescence (EL) performance of these polymers with configuration of ITO/PEDOT:PSS/Polymer/Alq3/LiF/Al was obtained from P1 (current efficiency was 4.2 Cd/A at 6V). | LIU DeAng GIBSON Gary BRUG James LAM Sity MAO Samuel S | 2011 | Science China Chemistry2011,54,4: | 3 |

| 15 | 用总氧自由基清除能力测定生物样品及抗氧化剂的总抗氧化能力显示文摘目的建立一项用于反映抗氧化剂或生物组织抗氧化能力的指标——总氧自由基清除能力(TOSC)。方法用气相色谱法测定几种抗氧化剂及小鼠肝、心、肾的TOSC。结果TOSC与抗氧化剂浓度有很好的剂量-效应关系,维生素C的TOSC高于谷胱甘肽的TOSC,小鼠心TOSC在几种组织中最高,不同个体小鼠间TOSC差异不大。结论TOSC水平与抗氧化剂和生物样品的浓度相关,且在小鼠间个体差异不大,可作为一项有意义的生物标志物用于化学品评价。 | 卢小英 叶怀庄 蔡德雷 徐立红 Paul K S Lam | 2003 | 环境与健康杂志2003,20,5: | 2 |
