穿越“生死” 这种创新疗法为攻克胶质母细胞瘤带来了什么？
穿越“生死” 这种创新疗法为攻克胶质母细胞瘤带来了什么？
2019 - 11 - 08
“5年后的今天，他们中将只剩下3名幸存者。”在谈到不久前刚刚接触过的100名胶质母细胞瘤（GBM）新患者时，Howard Fine博士语气很低沉，也透着几许无奈。作为威尔康奈尔医学院（Weill Cornell Medicine）的一名肿瘤学家，从医30年来，Howard Fine博士曾治疗过不下两万名GBM患者，不过，最终的结果却很扎心——“你现在很难再看到这些人了，因为他们基本上都死了。”Howard Fine博士所经历的，正是GBM在现实生活中的真实写照。神经胶质瘤是最常见的恶性原发性脑瘤，占所有原发性脑瘤的近四分之一，占所有恶性肿瘤的四分之三；而GBM又是最常见、最具侵袭性的胶质瘤类型，占所有胶质瘤的一半以上，仅在美国，每年就有约1.2万个新发病例。GBM是一个“致命杀手”，一旦被确诊，留给患者的时间平均只剩下15个月左右。GBM如此冷酷无情，自然惹得天怒人怨、人人喊打，不过，一个非常尴尬的事实却是：在与它的交锋中，医学界推出的各种手段胜绩寥寥，一种 “有心杀贼，无力回天”的感觉油然而生。面对GBM的嚣张气焰，专注于开发创新癌症疗法的DelMar Pharmaceuticals公司“明知山有虎，偏向虎山行”，开发出了一种对抗GBM的有力武器——VAL-083。接下来，DelMar Pharmaceuticals总裁兼首席执行官Saiid Zarrabian先生将为我们讲述V...

呼吸道微生物群影响流感易感性
呼吸道微生物群影响流感易感性
2019 - 01 - 21
冬季流感严重危害人类健康，甚至会威胁生命，我们究竟有什么办法预防流感呢？目前，美国密歇根大学 Betsy Foxman 和同事最新研究表明，呼吸道微生物群可能与流感易感性密切相关。这项研究报告发表在 1 月 9 日出版的《美国公共科学图书馆 · 综合》杂志上。流感病毒是流感病原体，主要侵袭目标是人体呼吸道，感染上皮细胞。鼻子和喉咙的上皮细胞被复杂的细菌群落包围，因此 Betsy Foxman 和同事推测认为，这些呼吸道微生物群可能与病毒相互作用，并在人体对流感预防方面充分发挥作用。在这项研究中，研究人员对 2012—2014 年登记的 144 个尼加拉瓜家庭进行了分析，这些家庭中有一位成员被确认患有流感，包括成年人和儿童的所有家庭成员都接受为期两个星期的监测。研究人员对每个家庭进行 5 次回访信息统计，对所有家庭成员的呼吸道微生物取样，并对监控测试者进行症状日志记录。研究者使用统计模型，对每次测试的家庭成员呼吸道微生物群分类为两个不同种群类型，尽管大约一半的测试者在研究测试过程中体内微生物群类型发生了变化。接下来，研究人员将参与者微生物类型与他们流感易感性进行了对比分析。结果发现，跨年龄组的一种呼吸道微生物类型显示出对流感的易感性降低，这种微生物类型在婴儿和儿童群体中并不常见，而且与年龄较大的青少年和成年人相比，其稳定性较低。虽然微生物种群和流感易感性之间的联系在这项研究...

中国科学家首次为微创胃癌治疗提供“中国模式”
中国科学家首次为微创胃癌治疗提供“中国模式”
2019 - 06 - 03
5月28日，南方医科大学南方医院教授李国新作为通讯作者发布了胃癌微创手术最新临床研究成果，该研究在全球范围内，首次提供了腹腔镜微创治疗局部进展期胃癌的高级别循证医学证据，揭示了腹腔镜微创手术治疗局部进展期胃癌具有确切的远期疗效与显着的微创获益。该研究在国际顶级医学期刊《美国医学会杂志》（以下简称为《JAMA》）在线发表，首次为世界胃癌治疗提供了“中国模式”，将使得更多患者受益于腹腔镜微创手术。胃癌是世界第二高发恶性肿瘤，42%的新发病例在中国，80%的患者在就诊时已发展至局部进展期，是严重影响国民健康的重大肿瘤疾病。2009年，李国新牵头组织，成立了中国腹腔镜胃肠外科研究组（CLASS），开展胃癌微创手术关键技术研究，建立了标准化手术操作方案。此多中心成员单位包括北京大学肿瘤医院（季加孚、苏向前、李子禹教授）、中国人民解放军301医院（杜晓辉教授）、复旦大学中山医院（孙益红教授）、上海交通大学瑞金医院（胡伟国教授）等。该研究组经过建立全国多中心数据库、开展系列多中心回顾性研究作为前期基础，于2012年启动了CLASS研究组的首项前瞻性临床研究（CLASS-01研究）。该研究旨在回答腹腔镜治疗局部进展期胃癌的安全性和肿瘤学疗效问题，以临床分期T2、T3或T4a的胃癌患者为研究对象，采用多中心、随机对照的试验设计，以3年无瘤生存率为主要研究终点，手术并发症、3年总生存率、术后关键恢复指...
