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
2Role of antispasmodics in the treatment of irritable bowel syndrome显示文摘Irritable bowel syndrome(IBS)is a long-lasting,relapsing disorder characterized by abdominal pain/discomfort and altered bowel habits.Intestinal motility impairment and visceral hypersensitivity are the key factors among its multifactorial pathogenesis,both of which require effective treatment.Voltage-gated calcium channels mediate smooth muscle contraction and endocrine secretion and play important roles in neuronal transmission.Antispasmodics are a group of drugs that have been used in the treatment of IBS for decades.Alverine citrate,a spasmolytic,decreases the sensitivity of smooth muscle contractile proteins to calcium,and it is a selective 5-HT1A receptor antagonist.Alverine,in combination with simethicone,has been demonstrated to effectively reduce abdominal pain and discomfort in a large placebo-controlled trial.Mebeverine is a musculotropic agent that potently blocks intestinal peristalsis.Non-placebo-controlled trials have shown positive effects of mebeverine in IBS regarding symptom control;nevertheless,in recent placebo-controlled studies,mebeverine did not exhibit superiority over placebo.Otilonium bromide is poorly absorbed from the GI tract,where it acts locally as an L-type calcium channel blocker,an antimuscarinic and a tachykinin NK2receptor antagonist.Otilonium has effectively reduced pain and improved defecation alterations in placebocontrolled trials in IBS patients.Pinaverium bromide is also an L-type calcium channel blocker that acts locally in the GI tract.Pinaverium improves motility disorders and consequently reduces stool problems in IBS patients.Phloroglucinol and trimethylphloroglucinol are non-specific antispasmodics that reduced pain in IBS patients in a placebo-controlled trial.Antispasmodics have excellent safety profiles.T-type calcium channel blockers can abolish visceral hypersensitivity in animal models,which makes them potential candidates for the development of novel therapeutic agents in the treatment of IBS.Anita Annaházi Richárd Róka András Rosztóczy Tibor Wittmann 2014World Journal of Gastroenterology2014,20,20:15
3Interplay between nitric oxide and VIP in CCK-8-induced phasic contractile activity in the rabbit sphincter of Oddi显示文摘AIM: The sphincter of Oddi (SO) plays an important role in delivery of bile into the duodenum. To establish whether vasoactive intestinal polypeptide (VIP) and nitric oxide (NO) were involved in phasic contractile activity of the rabbit SO stimulated by cholecystokinin-octapeptide (CCK-8).METHODS: Isolated SO muscle rings were cleaned of fat and mounted horizontally on two small L-shaped hooksone of which was connected to a force transducer for the measurement of isometric tension. The experiments were carried out in a thermostatically controlled (37±0.2℃)organ bath (5 mL) containing Krebs solution. The organ fluid was gassed with 95% O2 and 50 mL/L CO2 to keep the pH at 7.40±0.05. Contractile responses to CCK-8 (1μmol/L) were evaluated in the presence and absence of N^G-nitro-L-arginine (LNNA), an inhibitor of NO synthase (100μmol/L), and (p-chloro-D-Phe^6-Leu^17)-VIP (VIPa,30μmol/L), a VIP receptor antagonist.RESULTS: CCK-8 stimulated the phasic activity of the SO.NO synthase inhibition increased the frequency and amplitude of contractions with a slight increase in developed tension.Pre-incubation with VIPa also attenuated this CCK-8 effect.The combined application of LNNA and VIPa abolished the phasic activity of the muscle rings with a marked increase in tension in response to CCK-8.CONCLUSION: VIP and NO together contribute to an increase in phasic activity of SO.Attila Pálv(o|¨)lgyi Réka Sári József Németh Annamária Szabolcs István Nagy Péter Hegyi János Lonovics Zoltán Szilvássy 2005World Journal of Gastroenterology2005,11,21:11
4Screening and identification of mimotopes of the major shrimp allergen tropomyosin using one-bead-one- compound peptide libraries显示文摘one-bead-one-compound (OBOC ) 组合的肽图书馆是一个强大的工具识别 ligand 和受体相互作用。这里,我们使用了 OBOC 图书馆技术识别对主要贝壳变应原 tropomyosin 的免疫球蛋白 E (IgE ) epitopes 特定的 mimotopes。有 8-12 氨基酸残余的 OBOC 肽图书馆为 tropomyosin 的 IgE mimotopes 与贝壳过敏症从病人与浆液样品被屏蔽。25 mimotopes 从屏蔽被识别,他们到 tropomyosin 特定的 IgE 的有约束力的反应被肽 ELISA 证实。这些 mimotopes 能基于顺序相同被划分成七簇,并且由聚类的 mimotopes 的 EpiSearch 印射的 epitope 被执行描绘并且证实 mimotopes 的有效性。五从六预言的 epitopes 被发现与 tropomyosin 的以前识别的 epitopes 重叠。为了推进,证实 mimotopes 的模仿潜力, BALB/c 老鼠被使免疫, mimotopes 结合了到锁眼恋栈者 hemocyanin 和 assayed 让他们的能力导致 tropomyosin 特定的抗体。那收到的 mimotope 免疫被发现有 tropomyosin 特定的免疫球蛋白 G 的提高的水平的 BALB/c 老鼠,然而并非收到了无关的 mimotope 的老鼠。这研究用整个 sera 开创 OBOC 图书馆的成功的申请屏蔽并且识别多重虾变应原 mimotopes 并且验证他们在 vitro 使用的模仿潜力,在 vivo,并且在 silico 方法。Nicki YH Leung Christine YY Wai Marco HK Ho Ruiwu Liu Kit S Lam Jin Jun Wang Shang An Shu Ka Hou Chu Patrick SC Leung 2017Cellular & Molecular Immunology2017,14,3:6
5Epidemiologic characteristics of Helicobacter pylori infection in southeast Hungary显示文摘BACKGROUND Epidemiologic studies have revealed a decrease in the prevalence of Helicobacter pylori(H.pylori)infection in Western Europe.AIM To obtain data regarding the prevalence of H.pylori in Csongrád and Békés Counties in Hungary,evaluate the differences in its prevalence between urban and rural areas,and establish factors associated with positive seroprevalence.METHODS One-thousand and one healthy blood donors[male/female:501/500,mean age:40(19–65)years]were enrolled in this study.Subjects were tested for H.pylori IgG antibody positivity via enzyme-linked immunosorbent assay.Subgroup analysis by age,gender,smoking habits,alcohol consumption,and urban vs nonurban residence was also performed.RESULTS The overall seropositivity of H.pylori was 32%.It was higher in males(34.93%vs 29.2%,P=0.0521)and in rural areas(36.2%vs 27.94%,P=0.0051).Agricultural/industrial workers were more likely to be positive for infection than office workers(38.35%vs 30.11%,P=0.0095)and rural subjects in Békés County than those in Csongrád County(43.36%vs 33.33%,P=0.0015).CONCLUSION Although the prevalence of H.pylori infection decreased in recent decades in Southeast Hungary,it remains high in middle-aged rural populations.Generally accepted risk factors for H.pylori positivity appeared to be valid for the studied population.Lenke Bálint Andrea Tiszai Gábor Kozák Ilona Dóczi Veronika Szekeres Orsolya Inczefi Georgina Ollé Krisztina Helle Richárd Róka András Rosztóczy 2019World Journal of Gastroenterology2019,25,42:5

7Electrocardiographic markers of cardiac resynchronization therapy response:delayed time to intrinsicoid deflection onset in lateral leads显示文摘Cardiac resynchronization therapy(CRT)has emerged as an important intervention for patients with heart failure(HF)with reduced ejection fraction and delayed ventricular activation.In these patients,CRT has demonstrated to improve quality of life,promote reverse left ventricular(LV)remodeling,reduce HF hospitalizations,and extend survival.However,despite advancements in our understanding of CRT,a significant number of patients do not respond to this therapy.Several invasive and non-invasive parameters have been assessed to predict response to CRT,but the electrocardiogram(ECG)has remained as the prevailing screening method albeit with limitations.Ideally,an accurate,simple,and reproducible ECG marker or set of markers would dramatically overcome the current limitations.We describe the clinical utility of an old ECG parameter that can estimate ventricular activation delay:the onset to intrinsicoid deflection(ID).Based on the concept of direct measurement of ventricular activation time(intrinsic deflection onset),time to ID onset measures on the surface ECG the time that the electrical activation time takes to reach the area subtended by the corresponding surface ECG lead.Based on this principle,the time to ID on the lateral leads can estimate the delay activation to the lateral LV wall and can be used as a predictor for CRT response,particularly in patients with non-specific intraventricular conduction delay or in patients with left bundle branch block and QRS<150 ms.The aim of this review is to present the current evidence and potential use of this ECG parameter to estimate LV activation and predict CRT response.Rubén KA Tapia-Orihuela S Michael Gharacholou Samuel J Asirvatham Freddy Del-Carpio Munoz 2022Journal of Geriatric Cardiology2022,19,1:3
8Projection of the Zhujiang(Pearl) River Delta's potential submerged area due to sea level rise during the 21st century based on CMIP5 simulations显示文摘Projections of potential submerged area due to sea level rise are helpful for improving understanding of the influence of ongoing global warming on coastal areas. The Ensemble Empirical Mode Decomposition method is used to adaptively decompose the sea level time series in order to extract the secular trend component. Then the linear relationship between the global mean sea level(GMSL) change and the Zhujiang(Pearl) River Delta(PRD)sea level change is calculated: an increase of 1.0 m in the GMSL corresponds to a 1.3 m(uncertainty interval from1.25 to 1.46 m) increase in the PRD. Based on this relationship and the GMSL rise projected by the Coupled Model Intercomparison Project Phase 5 under three greenhouse gas emission scenarios(representative concentration pathways, or RCPs, from low to high emission scenarios RCP2.6, RCP4.5, and RCP8.5), the PRD sea level is calculated and projected for the period 2006–2100. By around the year 2050, the PRD sea level will rise 0.29(0.21 to 0.40) m under RCP2.6, 0.31(0.22 to 0.42) m under RCP4.5, and 0.34(0.25 to 0.46) m under RCP8.5, respectively.By 2100, it will rise 0.59(0.36 to 0.88) m, 0.71(0.47 to 1.02) m, and 1.0(0.68 to 1.41) m, respectively. In addition,considering the extreme value of relative sea level due to land subsidence(i.e., 0.20 m) and that obtained from intermonthly variability(i.e., 0.33 m), the PRD sea level will rise 1.94 m by the year 2100 under the RCP8.5scenario with the upper uncertainty level(i.e., 1.41 m). Accordingly, the potential submerged area is 8.57×103 km2 for the PRD, about 1.3 times its present area.XIA Jiangjiang YAN Zhongwei ZHOU Wen FONG Soi Kun LEONG Ka Cheng TANG Iu Man CHANG S W LEONG W K JIN Shaofei 2015Acta Oceanologica Sinica2015,34,9:3
9Increased duodenal expression of mi R-146a and-155 in pediatric Crohn's disease显示文摘AIM: To evaluate the role of micro RNA(mi R)-146 a,-155 and-122 in the duodenal mucosa of pediatric patients with Crohn's disease(CD) and the effect of transforming growth factor-β(TGF-β) on these mi Rs in duodenal epithelial and fibroblast cells.METHODS: Formalin-fixed, paraffin-embedded biopsies derived from the macroscopically inflamed(CD inflamed: n = 10) and intact(CD intact: n = 10) duodenal mucosa of pediatric CD patients and control children(C: n = 10) were examined. Expression of mi R-146 a,-155 and-122 was determined by realtime polymerase-chain reaction(PCR). The expression of the above mi Rs was investigated in recombinant human TGF-β(1 nmol/L, 24 h) or vehicle treated small intestinal epithelial cells(CCL-241) and primary duodenal fibroblast cells derived from healthy children as well.RESULTS: Expression of mi R-146 a was significantly higher in the inflamed duodenal mucosa compared to the intact duodenal mucosa of children with CD(CD inflamed: 3.21 ± 0.50 vs CD intact: 0.62 ± 0.26, p ≤ 0.01) and to the control group(CD inflamed: 3.21 ± 0.50 vs C: 1.00 ± 0.33, p ≤ 0.05). The expression of mi R-155 was significantly increased in the inflamed region of the duodenum compared to the control group(CD inflamed: 4.87 ± 1.02 vs Control: 1.00 ± 0.40, p ≤ 0.001). The expression of mi R-122 was unchanged in the inflamed or intact mucosa of CD patients compared to controls. TGF-β treatment significantly decreased the expression of mi R-155 in small intestinal epithelial cells(TGF-β: 0.7 ± 0.083 vs Control: 1 ± 0.09, p ≤ 0.05) and also the expression of mi R-146a(TGF-β: 0.67 ± 0.04 vs Control: 1 ± 0.15, p ≤ 0.01) and mi R-155(TGF-β: 0.72 ± 0.09 vs Control: 1 ± 0.06, p ≤ 0.05) in primary duodenal fibroblasts compared to corresponding vehicle treated controls. TGF-β treatment did not influence the expression of mi R-122.CONCLUSION: The elevated expression of mi R-146 a and-155 in the inflamed duodenal mucosa of CD patients suggests the role of these mi Rs in the pathomechanism of inflammatory bowel disease. Antiinflammatory TGF-β plays an important role in the regulation of the expression of these mi Rs.Dániel Szucs Nóra Judit Béres Réka Rokonay Kriszta Boros Katalin Borka Zoltán Kiss András Arató Attila J Szabó ádám Vannay Erna Sziksz Csaba Bereczki Gábor Veres 2016World Journal of Gastroenterology2016,22,26:2
10Atrophy of the left dorsolateral prefrontal cortex is associated with poor performance in verbal fluency in elderly poststroke women显示文摘This study aimed to investigate the association between atrophy in the prefrontal cortex with executive function and verbal fluency in elderly male and female patients poststroke.Thirty elderly female patients with non-aphasic ischemic stroke aged ≥ 60 years and 30 age-matched non-aphasic male patients with ischemic stroke were recruited.Automatic magnetic resonance imaging segmentation was used to assess the volume of the whole prefrontal cortex,along with its subdivisions:anterior cingulate cortex,orbitofrontal cortex and dorsolateral prefrontal cortex.The Semantic Verbal Fluency Test was administered at 3 and 15 months poststroke.At 3 months poststroke,left dorsolateral prefrontal cortex volume was significantly correlated with Verbal Fluency Test score in female patients only(partial coefficient = 0.453,P = 0.045),after controlling for age,education,diabetes,neurological deficit,white matter lesions volume,as well as the location and volume of infarcts.At 15 months poststroke,there remained a significant association between the left dorsolateral prefrontal cortex volume and Verbal Fluency Test(partial coefficient = 0.661,P = 0.001) and between the left prefrontal cortex volume and Verbal Fluency Test(partial coefficient = 0.573,P = 0.004) in female patients after the same adjustments.These findings indicate that atrophy of the left dorsolateral prefrontal cortex contributes to the impairment of verbal fluency in elderly female patients with stroke.Sex differences may be present in the neuropsychological mechanisms of verbal fluency impairment in patients with stroke.Yang-Kun Chen Wei-Min Xiao Defeng Wang Lin Shi Winnie CW Chu Vincent CT Mok Ka Sing Wong Gabor S Ungvari Wai Kwong Tang 2013Neural Regeneration Research2013,8,4:2
11Risk stratification in symptomatic intracranial atherosclerotic disease with conventional vascular risk factors and cerebral haemodynamics显示文摘Background and purpose Symptomatic intracranial atherosclerotic stenosis(sICAS)is associated with a considerable risk of recurrent stroke despite contemporarily optimal medical treatment.Severity of luminal stenosis in sICAS and its haemodynamic significance quantified with computational fluid dynamics(CFD)models were associated with the risk of stroke recurrence.We aimed to develop and compare stroke risk prediction nomograms in sICAS,based on vascular risk factors and these metrics.Methods Patients with 50%-99%sICAS confirmed in CT angiography(CTA)were enrolled.Conventional vascular risk factors were collected.Severity of luminal stenosis in sICAS was dichotomised as moderate(50%-69%)and severe(70%-99%).Translesional pressure ratio(PR)and wall shear stress ratio(WSSR)were quantified via CTA-based CFD modelling;the haemodynamic status of sICAS was classified as normal(normal PR&WSSR),intermediate(otherwise)and abnormal(abnormal PR&WSSR).All patients received guideline-recommended medical treatment.We developed and compared performance of nomograms composed of these variables and independent predictors identified in multivariate logistic regression,in predicting the primary outcome,recurrent ischaemic stroke in the same territory(SIT)within 1 year.Results Among 245 sICAS patients,20(8.2%)had SIT.The D2H2A nomogram,incorporating diabetes,dyslipidaemia,haemodynamic status of sICAS,hypertension and age≥50 years,showed good calibration(P for Hosmer-Lemeshow test=0.560)and discrimination(C-statistic 0.73,95%CI 0.60 to 0.85).It also had better performance in risk reclassification and provided larger net benefits in decision curve analysis,compared with nomograms composed of conventional vascular risk factors only,and plus the severity of luminal stenosis in sICAS.Sensitivity analysis in patients with anterior-circulation sICAS showed similar results.Conclusions The D2H2A nomogram,incorporating conventional vascular risk factors and the haemodynamic significance of sICAS as assessed in CFD models,could be a useful tool to stratify sICAS patients for the risk of recurrent stroke under contemporarily optimal medical treatment.Xuan Tian Hui Fang Linfang Lan Hing Lung Ip Jill Abrigo Haipeng Liu Lina Zheng Florence S Y Fan Sze Ho Ma Bonaventure Ip Bo Song Yuming Xu Jingwei Li Bing Zhang Yun Xu Yannie O Y Soo Vincent Mok Ka Sing Wong Thomas W Leung Xinyi Leng 2023Stroke & Vascular Neurology2023,8,1:2

13外科口罩覆盖N95自吸过滤式防护口罩:增加泄漏风险显示文摘本报告通过对相关流体力学和密封压力的分析建模,论证了当N95自吸过滤式防护口罩(N95 FFR)被外科口罩、布口罩或医用口罩(统称为外科口罩)覆盖时,将增加颜面部与口罩之间密封泄漏的潜在风险。以前发表的关于呼吸器压力和泄漏的试验研究也适用于此问题。在可预见的未来,正确使用N95 FFR仍将是保证医护人员安全的重要组成部分,特别是对于那些从事产生气溶胶操作(AGP)(如气管插管)的人员。在考虑泄漏风险时,重要的是要了解哪些因素可能会影响颜面部与口罩之间的密封性。N95 FFR的适配度和密封性会随着反复的穿戴和落纱而退化。据报道,一些N95 FFR再处理或回收技术可以加速这种退化。简而言之,N95型口罩密封性容易受损,可能会受到多种因素的影响。谭彩霞(译) 吴安华(审校) Mueller JT Karimi S Poterack KA 2021中国感染控制杂志2021,20,3:2
