| 1 | 胡萝卜软腐果胶杆菌巴西亚种(Pectobacterium carotovorum subsp.brasiliense)引起的黄瓜细菌性软腐病在中国发生显示文摘2014—2015年,在中国山东、山西、河北、河南、辽宁等省的黄瓜茎叶上发生了毁灭性的细菌性软腐病,造成了黄瓜产业严重的经济损失。黄瓜叶片、茎、叶柄和果实表面出现流胶;茎基部呈深褐色进而出现湿腐。受侵染的黄瓜叶边缘出现黄斑和湿腐症状,并逐渐扩散至叶片中心。从受侵染组织中分离出45个细菌菌株,在形态学特性鉴定、生理学、生物化学和16Sr RNA基因序列分析的基础上,将病原体鉴定为胡萝卜软腐果胶杆菌(Pectobacterium carotovorum)。多位点序列分析(MLSA)证实,分离菌株是胡萝卜软腐果胶杆菌巴西亚种[Pectobacterium carotovorum subsp.brasiliensis(Pcb)],病原菌归入进化枝II。重新分离获得与原始菌株相同的菌株,证实了分离菌株的致病力。寄主范围测试表明,该菌株具有广泛的寄主范围。目前为止,这是对Pcb引起的黄瓜软腐病——这一对黄瓜生产具有重要经济影响的病害在中国乃至全球范围内的首次报道。 | 冯志琴(译) meng x l chai a l shi y x xie x w ma z h li b j | 2017 | 中国植保导刊2017，37，7： | 10 |
| 2 | 标准辅助化疗基础上增加塞来昔布或安慰剂对Ⅲ期结肠癌患者无复发生存的疗效对比研究:CALGB/SWOG 80702(Alliance)随机对照研究显示文摘背景:既往观察性和随机对照研究已表明阿司匹林和环氧化酶-2(COX-2)抑制剂可降低肠道息肉和肠癌的发生风险。COX-2抑制剂塞来昔布治疗非转移性结肠癌的效果尚未明确。目的:本研究旨在明确FOLFOX辅助化疗基础上增加塞来昔布是否能提高Ⅲ期结肠癌患者的无复发生存率。方法:本研究为在美国、加拿大的654个中心开展的采用2×2析因设计的Ⅲ期临床研究,从2010年6月至2015年11月共纳入2526例Ⅲ期结肠癌患者,随访时间截止为2020年8月10日。以化疗时长和是否接受塞来昔布治疗作为2个随机因素,入组患者被随机分配接受3个月或6个月的FOLFOX辅助化疗(每两周1次)及随机接受联合3年塞来昔布(400 mg QD,n=1263)或安慰剂(n=1261)治疗。主要终点测量指标为3年无复发生存率(DFS),次要终点测量指标包括总生存、不良反应及心血管特异性不良事件。本次仅报道以是否接受塞来昔布治疗的随机分组研究结果。结果:入组患者平均年龄(61±11)岁,1134例(44.9%)为女性,最终2524例被纳入初步分析。患者治疗方案依从性(即接受塞来昔布或安慰剂治疗2.75年以上或持续治疗至复发、死亡或不可接受的不良事件)在塞来昔布组和安慰剂组分别为70.8%和69.9%。经过6年中位随访期,塞来昔布组和安慰剂组各有337例和363例患者出现疾病复发或死亡,3年无复发生率分别为76.3%和73.4%(疾病复发或死亡风险比HR=0.89,95%CI:0.76~1.03,P=0.12)。塞来昔布治疗对DFS的影响不会因辅助化疗时长(3个月或6个月)而存在差异(交互作用P=0.61)。两组5年生存率分别为84.3%和81.6%(死亡风险比HR=0.86,95%CI:0.72~1.04,P=0.13)。任何级别的高血压病发生率在塞来昔布组和安慰剂组分别为14.6%和10.9%,而2级或以上肌酐水平升高的发生率在两组分别为1.7%和0.5%。结论:对于Ⅲ期结肠癌患者,在标准辅助化疗的基础上联合3年塞来昔布治疗与安慰剂比较,对患者无复发生存率的改善不明显。 | 邱萌 MEYERHARDT J A SHI Q FUCHS C S | 2021 | 结直肠肛门外科2021，27，3： | 6 |

| 4 | A survey of FLS2 genes from multiple citrus species identifies candidates for enhancing disease resistance to Xanthomonas citri ssp. citri.显示文摘Pathogen-associated molecular patterns(PAMPs)-triggered immunity(PTI)is an important component of plant innate immunity.In a previous study,we showed that the PAMP flg22 from Xanthomonas citri ssp.citri(Xflg22),the causal agent of citrus canker,induced PTI in citrus,which correlated with the observed levels of canker resistance.Here,we identified and sequenced two bacterial flagellin/flg22 receptors(FLS2-1 and FLS2-2)from‘Duncan’grapefruit(Citrus paradisi,CpFLS2-1 and CpFLS2-2)and‘Sun Chu Sha’mandarin(C.reticulata,CrFLS2-1 and CrFLS2-2).We were able to isolate only one FLS2 from‘Nagami’kumquat(Fortunella margarita,FmFLS2-1)and gene flanking sequences suggest a rearrangement event that resulted in the deletion of FLS2-2 from the genome.Phylogenetic analysis,gene structure and presence of critical amino acid domains all indicate we identified the true FLS2 genes in citrus.FLS2-2 was more transcriptionally responsive to Xflg22 than FLS2-1,with induced expression levels higher in canker-resistant citrus than in susceptible ones.Interestingly,‘Nagami’kumquat showed the highest FLS2-1 steady-state expression levels,although it was not induced by Xflg22.We selected FmFLS2-1,CrFLS2-2 and CpFLS2-2 to further evaluate their capacity to enhance bacterial resistance using Agrobacterium-mediated transient expression assays.Both FmFLS2-1 and CrFLS2-2,the two proteins from canker-resistant species,conferred stronger Xflg22 responses and reduced canker symptoms in leaves of the susceptible grapefruit genotype.These two citrus genes will be useful resources to enhance PTI and achieve resistance against canker and possibly other bacterial pathogens in susceptible citrus types. | Qingchun Shi Vicente J Febres Jeffrey B Jones Gloria A Moore | 2016 | Horticulture Research2016，3，1： | 3 |
