| 1 | Current concepts in ameloblastoma-targeted therapies in B-raf proto-oncogene serine/threonine kinase V600E mutation: Systematic review显示文摘BACKGROUND Ameloblastomas are common benign epithelial odontogenic neoplasms that present an aggressive and unpredictable behavior that may modify treatment strategies.Different signaling pathways that participate in the progression of these tumors have been identified.B-raf proto-oncogene serine/threonine kinase(BRAF)is a protein involved in the behavior of ameloblastomas,and it is related to many cell mechanisms.BRAF gene mutations have been identified in ameloblastomas,of which the BRAF V600E(valine substituted by glutamic acid at amino acid 600)mutation has been the most common and can be present concomitantly with other mutations that may be involved in its behavior.Targeted therapies have been used as an alternative in the case of resistance or contraindications to conventional treatments.AIM To document the presence of BRAF V600E and additional mutations,their behavior,and targeted therapies in these tumors.METHODS An electronic literature search was conducted according to PRISMA guidelines in PubMed/MEDLINE,Cochrane,EMBASE,and SpringerLink using the terms“ameloblastomas”,“BRAF V600E”,“additional mutations”,and“targeted therapies”.Ameloblastomas were classified according to WHO guidelines.Inclusion criteria were articles in English,published not more than 10 years ago,and studies with laboratory works related to BRAF V600E.Articles were evaluated by two independent reviewers and retrieved for full-text evaluation.The EBLIP Critical Appraisal Checklist was used to evaluate the quality of the eligible studies.Descriptive statistical analysis was performed.RESULTS Two independent reviewers,with a substantial concordance indicated by a kappa coefficient of k=0.76,evaluated a total of 19 articles that were included in this study.The analysis registered 521 conventional ameloblastomas(AM),81 unicystic ameloblastomas(UA),13 ameloblastic carcinomas(AC),three metastatic ameloblastomas(MA),and six peripheral ameloblastomas(PA),of which the histopathological type,anatomic location,laboratory tests,expression of BRAF mutation,and additional mutations were registered.The BRAF V600E mutation was found in 297 AM(57%),63 UA(77.7%),3 AC(23%),1 MA(50%),and 5 PA(83.3%).Follicular type predominated with a total of 116 cases(40%),followed by plexiform type with 63 cases(22.1%).Furthermore,both types presented additional mutations,in which alterations in JAK3 P132T,SMARCB1,PIK3CA,CTNNB1,SMO,and BRAF G606E genes were found.Four case reports were found with targeted therapy to BRAF V600E.CONCLUSION The identification of BRAF V600E and additional mutations as an aid in targeted therapies has been a breakthrough in alternative treatments of ameloblastomas where surgical treatments are contraindicated. | Rogelio González-González Sandra López-Verdín Jesús Lavalle-Carrasco Nelly Molina-Frechero Mario Isiordia-Espinoza Ramón G Carreón-Burciaga Ronell Bologna-Molina | 2020 | World Journal of Clinical Oncology2020，11，1： | 6 |
| 2 | 抗炎介质表达缺陷参与中性粒细胞型支气管哮喘发病机制:半乳糖凝集素-3和白细胞介素-1RA/白细胞介素-1beta比例显著下降显示文摘支气管哮喘(哮喘)是具有异质性的气道炎症性疾病,其主要特点表现为气道高反应和可变的气流受限。在哮喘的发病机制中,过敏原诱导的TH2淋巴细胞激活以及IL-5介导的嗜酸粒细胞渗出起到重要的作用。近年来发现超过50%的哮喘患者气道的嗜酸粒细胞水平并不增高,并将这种亚型定义为非嗜酸粒细胞型哮喘。其中部分患者表现为气道中性粒细胞明显增高,称为中性粒细胞型哮喘。 | 高鹏 Peter G Gibson Katherine J Baines Ian A Yang John W Upham Paul N Reynolds Sandra Hodge Alan L James Christine Jenkins Matthew J Peters 张捷 Jodie L Simpson | 2016 | 中华结核和呼吸杂志2016，39，11： | 5 |
| 3 | Gastro-duodenal disease in Africa: Literature review and clinical data from Accra, Ghana显示文摘Gastroduodenal disease(GDD)was initially thought to be uncommon in Africa.Amongst others,lack of access to optimal health infrastructure and suspicion of conventional medicine resulted in the reported prevalence of GDD being significantly lower than that in other areas of the world.Following the increasing availability of flexible upper gastro-intestinal endoscopy,it has now become apparent that GDD,especially peptic ulcer disease(PUD),is prevalent across the continent of Africa.Recognised risk factors for gastric cancer(GCA)include Helicobater pylori(H.pylori),diet,Epstein-Barr virus infection and industrial chemical exposure,while those for PUD are H.pylori,non-steroidal antiinflammatory drug(NSAID)-use,smoking and alcohol consumption.Of these,H.pylori is generally accepted to be causally related to the development of atrophic gastritis(AG),intestinal metaplasia(IM),PUD and distal GCA.Here,we perform a systematic review of the patterns of GDD across Africa obtained with endoscopy,and complement the analysis with new data obtained on premalignant gastric his-topathological lesions in Accra,Ghana which was compared with previous data from Maputo,Mozambique.As there is a general lack of structured cohort studies in Africa,we also considered endoscopy-based hospital or tertiary centre studies of symptomatic individuals.In Africa,there is considerable heterogeneity in the prevalence of PUD with no clear geographical patterns.Furthermore,there are differences in PUD within-country despite universally endemic H.pylori infection.PUD is not uncommon in Africa.Most of the African tertiary-centre studies had higher prevalence of PUD when compared with similar studies in western countries.An additional intriguing observation is a recent,ongoing decline in PUD in some African countries where H.pylori infection is still high.One possible reason for the high,sustained prevalence of PUD may be the significant use of NSAIDs in local or over-the-counter preparations.The prevalence of AG and IM,were similar or modestly higher over rates in western countries but lower than those seen in Asia..In our new data,sampling of 136 patients in Accra detected evidence of pre-malignant lesions(AG and/or IM)in 20 individuals(14.7%).Likewise,the prevalence of pre-malignant lesions,in a sample of 109 patients from Maputo,were 8.3%AG and 8.3%IM.While H.pylori is endemic in Africa,the observed prevalence for GCA is rather low.However,cancer data is drawn from country cancer registries that are not comprehensive due to considerable variation in the availability of efficient local cancer reporting systems,diagnostic health facilities and expertise.Validation of cases and their source as well as specificity of outcome definitions are not explicit in most studies further contributing to uncertainty about the precise incidence rates of GCA on the continent.We conclude that evidence is still lacking to support(or not)the African enigma theory due to inconsistencies in the data that indicate a particularly low incidence of GDD in African countries. | Timothy N Archampong Richard H Asmah Cathy J Richards Vicki J Martin Christopher D Bayliss Edília Botao Leonor David Sandra Beleza Carla Carrilho | 2019 | World Journal of Gastroenterology2019，25，26： | 3 |

| 18 | Depicting the battle between nectarine and Monilinia laxa:the fruit developmental stage dictates the effectiveness of the host defenses and the pathogen’s infection strategies显示文摘Infections by the fungus Monilinia laxa,the main cause of brown rot in Europe,result in considerable losses of stone fruit.Herein,we present a comprehensive transcriptomic approach to unravel strategies deployed by nectarine fruit and M.laxa during their interaction.We used M.laxa-inoculated immature and mature fruit,which was resistant and susceptible to brown rot,respectively,to perform a dual RNA-Seq analysis.In immature fruit,host responses,pathogen biomass,and pathogen transcriptional activity peaked at 14–24 h post inoculation(hpi),at which point M.laxa appeared to switch its transcriptional response to either quiescence or death.Mature fruit experienced an exponential increase in host and pathogen activity beginning at 6 hpi.Functional analyses in both host and pathogen highlighted differences in stage-dependent strategies.For example,in immature fruit,M.laxa unsuccessfully employed carbohydrate-active enzymes(CAZymes)for penetration,which the fruit was able to combat with tightly regulated hormone responses and an oxidative burst that challenged the pathogen’s survival at later time points.In contrast,in mature fruit,M.laxa was more dependent on proteolytic effectors than CAZymes,and was able to invest in filamentous growth early during the interaction.Hormone analyses of mature fruit infected with M.laxa indicated that,while jasmonic acid activity was likely useful for defense,high ethylene activity may have promoted susceptibility through the induction of ripening processes.Lastly,we identified M.laxa genes that were highly induced in both quiescent and active infections and may serve as targets for control of brown rot. | Marta Balsells-Llauradó Christian J.Silva Josep Usall Núria Vall-llaura Sandra Serrano-Prieto Neus Teixidó Saskia D.Mesquida-Pesci Antonieta de Cal Barbara Blanco-Ulate Rosario Torres | 2020 | Horticulture Research2020，7，1： | 1 |
