摘要: 肺炎链球菌(S.pn)菌毛是肺炎链球菌的胞外结构部分,也是菌体的黏附和毒力因子,在致病过程中起重要作用,作为蛋白疫苗的候选抗原之一,在联合免疫的疫苗策略中颇具潜力。本文以近年来S.pn菌毛蛋白基因、结构和生物学功能的研究成果为中心,结合菌毛作为蛋白疫苗候选因子的免疫保护效果进行综述,旨在系统地描述S.pn菌毛结构和功能的研究现状,并为后续疫苗研究提供新的思路。

  • 肺结节的外科治疗策略

    作者:李何子;汪天虎; 期刊:《重庆医学》 2019年2期

    肺结节是最常见的影像学改变之一。随着健康检查的普及,越来越多的肺结节特别是肺小结节被发现,这些体检发现的肺结节不但让患者高度紧张,也一度困扰医务人员。为了规范化地进行随访和治疗,近年国内外已出台了很多指南和专家共识。肺结节是否应该进行外科治疗,需要临床专科医生按照指南来进行规范和详细地评估。对于明确需要手术的患者,目前提倡精准化、微创化和个性化的进行治疗。为了更好地把握肺结节的手术适应证、手术策略和选择合适的手术方式,本文就此进行相关概述。

  • 早期肺腺癌患者预后及早期复发病理特征的研究

    目的 术后复发转移是早期肺腺癌治疗失败的主要原因,探寻其临床病理特征有利于筛选预测复发转移的高危患者。方法 随访分析157例手术治疗、病理确诊为早期肺腺癌患者的整体复发及生存时间,重点探讨早期复发患者的临床病理特征。结果 157例早期肺腺癌患者的中位无复发生存(RFS)时间为55.0个月,1、2和5年RFS率分别为86.0%、75.8%和45.0%;总生存率分别为98.1%、96.0%和84.1%。157例早期肺腺癌患者中,69例复发转移,其中1年内早期复发者为22例(14.0%)。统计分析结果显示,肿瘤大小、组织学亚型是影响早期肺腺癌术后患者RFS的危险因素(P<0.05),低分化和非贴壁为主型可能是早期复发患者的病理学特征。结论 肿瘤直径大于2cm、非贴壁为主型和低分化可能是预测早期肺腺癌复发与早期复发的重要因素。
