| 1 | 国际疼痛研究协会疼痛定义修订版:概念、挑战和折中显示文摘现行国际疼痛研究协会(IASP)将疼痛定义为'与实际或潜在组织损伤,或描述的类似损伤相关的一种不愉快的感觉和情感体验',该定义是由一个分类小组委员会推荐,并于1979年被IASP理事会所采纳。这一定义已被疼痛领域的卫生保健专业人士和研究人员广泛接受,并被一些行业、政府及非政府组织(包括世界卫生组织)所采用。近年来,一些业内人士认为,随着对疼痛更深入的了解,有必要对这个定义重新审定,并提出了修改建议。因此,2018年,IASP成立了一个主席特别工作小组,该小组是由14名来自多个国家的在疼痛相关的临床和基础科学方面拥有广泛专业知识的人员组成,其任务是评估现行定义及其附带注释,并对其保留还是修改提出建议。本文提供了关键概念的摘要、对IASP会员和公众评论的分析以及两年内委员会对疼痛定义和注释的最终修订意见。特别工作小组最后建议将疼痛定义修改为'与组织损伤或潜在组织损伤相关或类似相关的一种不愉快的感觉和情感体验',并将原来的附带注释更新为一系列简要说明并提供相关词源。今年年初,IASP理事会一致接受了修订后的定义和注释。 | Raja SN.Carr DB Cohen M.Finnerup NB Flor H.Gibson S Keefe FJ.Mogil JS Ringkamp M.Sluka KA Song XJ.Stevens B Sullivan MD.Tutelman PR Ushida T.Vader K 程志祥(译) 许继军(译) 程建国(审校) 刘先国(审校) 刘延青(审校) | 2020 | 中华疼痛学杂志2020，16，5： | 137 |
| 2 | 评估大气细颗粒物暴露引起的全球疾病负担的一个综合风险函数显示文摘[背景]评估由于环境空气中细颗粒物(PM2.5)长期暴露引起的疾病负担,需要了解相对风险度(RR)函数的图形和幅度。然而,在世界上很多观察到高PM2.5环境浓度的地方,都缺乏足够的直接证据确定死亡RR函数的图形。[目的]建立可用于全球PM2.5暴露范围内成人死因的RR函数:缺血性心脏病(IHD)、脑血管疾病(脑卒中)、慢性阻塞性肺病(COPD)和肺癌(LC)。建立急性下呼吸道感染(ALRI)发病的RR函数,用于估算〈5岁的儿童中死亡率和健康生活损失年数。[方法]通过整合现有的来自于环境空气污染(AAP)、二手烟草烟雾、家用固体烹饪用燃料和主动吸烟(AS)等研究的RR信息,拟合综合暴露-反应(IER)模型。采用颗粒物质的吸入剂量,通过转化AS暴露来估计全年PM2.5的暴露当量。在估算全球环境PM2.5浓度的基础上,得出各国的人群归因分数(PAFs)。[结果]与以往负担评估中使用的其他7种模型相比,IER模型是一种优越的RR预测方法。在不同国家中,归因于AAP暴露的PAF百分数各不相同,分别为:IHD,2~41;脑卒中,1~43;COPD,〈1~21;LC,〈1~25;ALRI,〈1~38。[结论]我们建立了一种以细颗粒物为基础的RR模型,它通过整合来自不同类型的燃烧所产生颗粒物排放的RR信息,涵盖全球范围的暴露。当获得新的RR信息时,可以对这个模型进行更新。 | Richard T.Burnett C.Arden Pope III Majid Ezzati Casey Olives Stephen S.Lim Sumi Mehta Hwashin H.Shin Gitanjali Singh Bryan Hubbell Michael Brauer H.Ross Anderson Kirk R.Smith John R.Balmes Nigel G.Bruce Haidong Kan Francine Laden Annette Prüss-Ustün Michelle C.Turner Susan M.Gapstur W.Ryan Diver Aaron Cohen 何蓉 张伊人 金泰廙 | 2014 | 环境与职业医学2014，31，11： | 80 |
| 3 | BCLC策略:预后预测和治疗推荐2022版更新显示文摘2018版BCLC预后和治疗推荐策略发布后,肝细胞癌(简称HCC)的研究又取得了重大进展。本次更新基于肝癌各领域的研究进展结果。重点关注影响策略的重要研究进展。虽然近年的研究结果成绩斐然,但将其引入为临床医生和研究者提供行动依据的循证模型指南来说证据效力依然不够确切。本文对该问题进行分析,阐述了为HCC患者制定个体化治疗临床决策所需的批判性思维和专业知识。 | Reig M Forner A Rimola J Ferrer-Fabrega J Burrel M Garcia-Criado A Kelley RK Galle PR Mazzaferro V Salem R Sangro B Singal AG Vogel A Fuster J Ayuso C Bruix J 刘永凡(摘译) 崔笑(摘译) 耿小平(审校) | 2022 | 肝胆外科杂志2022，30，5： | 80 |
| 4 | Portal vein thrombosis in cirrhosis: Controversies and latest developments显示文摘Portal vein thrombosis(PVT) is encountered in livercirrhosis, particularly in advanced disease. It has been a feared complication of cirrhosis, attributed to significant worsening of liver disease, poorer clinical outcomes and potential inoperability at liver transplantation; also catastrophic events such as acute intestinal ischaemia. Optimal management of PVT has not yet been addressed in any consensus publication.We review current literature on PVT in cirrhosis; its prevalence, pathophysiology, diagnosis, impact on the natural history of cirrhosis and liver transplantation,and management. Studies were identified by a search strategy using MEDLINE and Google Scholar. The incidence of PVT increases with increasing severity of liver disease: less than 1% in well-compensated cirrhosis, 7.4%-16% in advanced cirrhosis. Prevalence in patients undergoing liver transplantation is 5%-16%.PVT frequently regresses instead of uniform thrombus progression. PVT is not associated with increased risk of mortality. Optimal management has not been addressed in any consensus publication. We propose areas for future research to address unresolved clinical questions. | Damian J Harding M Thamara PR Perera Frederick Chen Simon Olliff Dhiraj Tripathi | 2015 | World Journal of Gastroenterology2015，21，22： | 42 |
| 5 | Mesenchymal stromal cells-exosomes:a promising cell-free therapeutic tool for wound healing and cutaneous regeneration显示文摘Cutaneous regeneration at the wound site involves several intricate and dynamic processes which require a series of coordinated interactions implicating various cell types,growth factors,extracellular matrix(ECM),nerves,and blood vessels.Mesenchymal stromal cells(MSCs)take part in all the skin wound healing stages playing active and beneficial roles in animal models and humans.Exosomes,which are among the key products MSCs release,mimic the effects of parental MSCs.They can shuttle various effector proteins,messenger RNA(mRNA)and microRNAs(miRNAs)to modulate the activity of recipient cells,playing important roles in wound healing.Moreover,using exosomes avoids many risks associated with cell transplantation.Therefore,as a novel type of cell-free therapy,MSC-exosome-mediated administration may be safer and more efficient than whole cell.In this review,we provide a comprehensive understanding of the latest studies and observations on the role of MSC-exosome therapy in wound healing and cutaneous regeneration.In addition,we address the hypothesis of MSCs microenvironment extracellular vesicles(MSCs-MEVs)or MSCs microenvironment exosomes(MSCs-MExos)that need to take stock of and solved urgently in the related research about MSC-exosomes therapeutic applications.This review can inspire investigators to explore new research directions of MSC-exosome therapy in cutaneous repair and regeneration. | Peng Hu Qinxin Yang Qi Wang Chenshuo Shi Dali Wang Ubaldo Armato Ilaria Dal Prà Anna Chiarini | 2019 | Burns & Trauma2019，7，1： | 20 |
| 6 | Current status and recent advances of liver transplantation from donation after cardiac death显示文摘The last decade saw increased organ donation activity from donors after cardiac death (DCD). This contributed to a signif icant proportion of transplant activity. Despite certain drawbacks, liver transplantation from DCD donors continues to supplement the donor pool on the backdrop of a severe organ shortage. Understanding the pathophysiology has provided the basis for modulation of DCD organs that has been proven to be effective outside liver transplantation but remains experimental in liver transplantation models. Research continues on how best to further increase the utility of DCD grafts. Most of the work has been carried out exploring the use of organ preservation using machine assisted perfusion. Both ex-situ and in-situ organ perfusion systems are tested in the liver transplantation setting with promising results. Additional techniques involved pharmacological manipulation of the donor, graft and the recipient. Ethical barriers and end-of-life care pathways are obstacles to widespread clinical application of some of the recent advances to practice. It is likely that some of the DCD offers are in fact probably 'prematurely' of-fered without ideal donor management or even prior to brain death being established. The absolute benef its of DCD exist only if this form of donation supplements the existing deceased donor pool; hence, it is worthwhile revisiting organ donation process enabling us to identify counter remedial measures. | M Thamara PR Perera Simon R Bramhall | 2011 | World Journal of Gastrointestinal Surgery2011，3，11： | 16 |

| 8 | Post-Mesozoic Transformation of Tectonic Domain in Southeastern China and Its Geodynamic Mechanism显示文摘Since the Mesozoic and Cenozoic, a transformation from a Tethyan Himalayan tectonic domain into a circum Pacific tectonic domain from Indosinian to Yanshanian is indicated in this paper, resulting in conspicuous changes in geophysics, tectono magmatic distribution, lithofacies and paleo geography, tectonic system in southeastern China. Tectonic analysis shows that the tectonic framework resulted from the compounding, transforming and superimposing of the two tectonic domains. The geodynamic mechanism of the transformation is mainly shown as the transverse and longitudinal heterogeneity of lithosphere, and the exchange between the crust and the mantle. | Wu Ganguo Zhang Da Faculty of Earth Sciences and Mineral Resources, China University of Geosciences, Beijing 100083, China Chen Bailin Institute of Geomechanics, CAGS, Beijing 100081, China Wu Jianshe Institute of Geological Survey of Fujian Pr | 2000 | Journal of Earth Science2000，19，3： | 12 |

| 10 | Plants as concept generators for biomimetic light-weight structures with variable stiffness and self-repair mechanisms显示文摘Plants possess many structural and functional properties that have a high potential to serve as concept generators for the production of biomimetic technical materials and structures. We present data on two features of plants (variable stiffness due to pressure changes in cellular structures and rapid self-repair functions) that may be used as models for biomimetic projects. | Thomas Speck Tom Masselter Bettina Prüm Olga Speck Rolf Luchsinger Siegfried Fink | 2004 | Journal of Bionic Engineering2004，1，4： | 10 |
| 11 | Organic matter produced by algae and cyanobacteria: Quantitative and qualitative characterization显示文摘This work aims at characterizing organic matter produced by an alga Euglena gracilis and a cyanobacteria Microcystis aeruginosa and assessing the evolution of its characteristics during growth.A culture medium was optimized.The species growth phases were monitored using both visible spectrophotometry and flow cytometry cell counting.Organic matter fractionation according to hydrophobicity and specific UV absorbance(SUVA) index were used to specifically characterize the produced algal organic matter(AOM).The AOM characteristics were both growth phase and species dependent.However,a similar evolution was observed.The hydrophilic fraction(HPI) was the major fraction whatever the growth phases and was almost the only one produced during lag and exponential phases.It represented around 75% of AOM during exponential phase and then decreased when the stationary phase appeared.It represented 46% and 60% of the AOM during late decline phase for the cyanobacteria and the alga respectively.The hydrophobic(HPO) and transphilic(TPH) fractions started to appear from the beginning of the stationary phase with more hydrophobic compounds coming from intracellular organic material of dying cells.HPO and TPH percentages still increased during the decline phase probably because of two additional processes:photo-dissolution and leaching of particulate organic matter from cells fragments.A comparison of AOM during late decline phase and natural organic matter(NOM) from Glane River(France) underlined that AOM was more hydrophilic and presented a lower SUVA for each fractions than NOM.However,the difference between NOM and AOM hydrophobicity narrowed during decline phase. | Maud Leloup Rudy Nicolau Virginie Pallier Claude Yprmian Geneviève Feuillade-Cathalifaud | 2013 | Journal of Environmental Sciences2013，25，6： | 10 |

| 13 | Near-infrared fluorescence sentinel lymph node detection in gastric cancer: A pilot study显示文摘AIM: To investigate feasibility and accuracy of nearinfrared fluorescence imaging using indocyanine green: nanocolloid for sentinel lymph node(SLN) detection in gastric cancer.METHODS: A prospective, single-institution, phaseI feasibility trial was conducted. Patients suffering from gastric cancer and planned for gastrectomy were included. During surgery, a subserosal injection of 1.6 m L ICG:Nanocoll was administered around the tumor. NIR fluorescence imaging of the abdominal cavity was performed using the Mini-FLARE? NIR fluorescence imaging system. Lymphatic pathways and SLNs were visualized. Of every detected SLN, the corresponding lymph node station, signal-to-background ratio and histopathological diagnosis was determined. Patients underwent standard-of-care gastrectomy. Detected SLNs outside the standard dissection planes were also resected and evaluated.RESULTS: Twenty-six patients were enrolled. Four patients were excluded because distant metastases were found during surgery or due to technical failure of the injection. In 21 of the remaining 22 patients, at least 1 SLN was detected by NIR Fluorescence imaging(mean 3.1 SLNs; range 1-6). In 8 of the 21 patients, tumor-positive LNs were found. Overall accuracy of the technique was 90%(70%-99%; 95%CI), which decreased by higher p T-stage(100%, 100%, 100%, 90%, 0% for respectively Tx, T1, T2, T3, T4 tumors). All NIR-negative SLNs were completely effaced by tumor. Mean fluorescence signal-to-background ratio of SLNs was 4.4(range 1.4-19.8). In 8 of the 21 patients, SLNs outside the standard resection plane were identified, that contained malignant cells in 2 patients.CONCLUSION: This study shows successful use of ICG:Nanocoll as lymphatic tracer for SLN detection in gastric cancer. Moreover, tumor-containing LNs outside the standard dissection planes were identified. | Quirijn RJG Tummers Leonora SF Boogerd Wobbe O de Steur Floris PR Verbeek Martin C Boonstra Henricus JM Handgraaf John V Frangioni Cornelis JH van de Velde Henk H Hartgrink Alexander L Vahrmeijer | 2016 | World Journal of Gastroenterology2016，22，13： | 9 |

| 17 | Hearing and Cochlear structures in a Swine Model显示文摘Objective To study the audition and inner ear structure in a normal swine model.Methods Auditory brainstem responses(ABRs) were determined in swine at 1 day and 1 month after birth.The form of the cochlea and hair cells were examined under a scanning electron microscope and on cochlear slices.Results ABR thresholds at 1 day and 1 month post-birth were between 40 and 50 dB SPL.The latencies of waves I,III and V in 1 day old swine were 1.97 ± 0.13,3.01± 0.16 and 4.26±0.20 ms,respectively.At 1 month,the lantancies of waves I,III and V were 2.01 ± 0.05,3.11±0.08 and 4.65 ± 0.14 ms,respectively,slightly longer than those at 1 day,although not statistically significant(p>0.05).The swine cochlea was constituted of 3 and a half turns and the cochlear hair cells lined up in four rows.Hair cell cilia in the apical turn were longer than those in other turns.Conclusions The swine cochlea is mature at the time of birth.Swine ABR thresholds are slightly higher than humans and rats.Swine appears to be a precocial animal species. | GUO Wei-wei1,Cheng Lei2,Liu Hui-zhan1,Sun Jian-he1,YANG Shi-ming1,1 Department of Otolaryngology,Head & Neck Surgery,Institute of Otolaryngology,Chinese PLA General Hospital,Beijing 100853,China 2 State Rey laboratory for Agrobio technology China Agrical universiy Beijing 100193,PR,China | 2010 | Journal of Otology2010，5，2： | 7 |
| 18 | Antagonizing amyloid-β/calcium-sensing receptor signaling in human astrocytes and neurons: a key to halt Alzheimer's disease progression?显示文摘Astrocytes' roles in late-onset Alzheimer's disease(LOAD) promotion are important, since they survive soluble or fibrillar amyloid-β peptides(Aβs) neurotoxic effects, undergo alterations of intracellular and intercellular Ca2+ signaling and gliotransmitters release via the Aβ/α7-n ACh R(α7-nicotinic acetylcholine receptor) signaling, and overproduce/oversecrete newly synthesized Aβ42 oligomers, NO, and VEGF-A via the Aβ/Ca SR(calcium-sensing receptor) signaling. Recently, it was suggested that the NMDAR(N-methyl-D-aspartate receptor) inhibitor nitromemantine would block the synapse-destroying effects of Aβ/α7-n ACh R signaling. Yet, this and the progressive extracellular accrual and spreading of Aβ42 oligomers would be stopped well upstream by NPS 2143, an allosteric Ca SR antagonist(calcilytic). | Ilaria Dal Prà Anna Chiarini Ubaldo Armato | 2015 | Neural Regeneration Research2015，10，2： | 6 |
