1帕博利珠单抗单用或与放疗联用治疗转移性非小细胞肺癌:两个随机试验的汇总分析显示文摘背景放疗可以提高整个机体对免疫治疗的应答。在Ⅱ期PEMBRO-RT研究和Ⅰ/Ⅱ期MDACC研究中,患有转移性非小细胞肺癌(NSCLC)的患者被随机分配入组,接受免疫治疗(帕博利珠单抗)+放疗联合疗法,或免疫治疗单一疗法。当上述2个研究单独分析时,联合疗法组显示出潜在获益。由于每个研究的样本量较小,缓解率和结局并未显示出统计学意义,然而却有显著的临床获益。因此,本研究进行汇总分析,来判断放疗是否会改善转移性NSCLC患者的免疫治疗应答。方法PEMBRO-RT和MDACC研究纳入标准:患者年龄≥18岁,患有转移性NSCLC,且有≥1处未经放疗照射的病灶,以便进行射野外应答监测。PEMBRO-RT研究纳入曾接受过化疗患者,MDACC研究纳入曾接受过治疗或新诊断患者。2个研究中的患者均未接受过免疫治疗。在PEMBRO-RT研究中患者被等比例随机分配入组,并根据吸烟状态进行分层(分为<10年组和≥10年组)。MDACC研究的患者根据放疗计划可行性被等比例随机分配入2个受试组。由于联合治疗组的干预本质,每个研究中的放疗均不适用盲法。在2个研究中,不论是否进行放疗,均静脉滴入帕博利珠单抗(每3周200 mg)。在PEMBRO-RT研究中,在放疗(24 Gy 3次分割照射)结束后1周给予第1剂帕博利珠单抗。在MDACC研究中,在第1次放疗(50 Gy 4次分割照射或45 Gy 15次分割照射)同时给予帕博利珠单抗。仅检测未经照射病灶的应答。本研究的终点为最佳射野外(远隔)应答率(ARR)、最佳射野外疾病控制率(ACR)、12周时ARR、12周时ACR、无进展生存期(PFS)和总生存期(OS)。2个研究的意向治疗(ITT)人群均纳入分析。PEMBRO-RT研究(NCT02492568)和MDACC研究(NCT02444741)均在ClinicalTrials.gov上注册。发现纳入148例患者,76例接受帕博利珠单抗治疗,72例接受帕博利珠单抗+放疗治疗。所有患者随访时间中位数为33个月[四分位距(IQR):32.4~33.6]。148例患者中124例(84%)组织学特征为非鳞癌,111例(75%)患者曾经接受过化疗。组间没有基线特征差异,包括PD-L1表达状态和转移灶体积。最常见的照射部位为肺转移灶(39%,28/72)、胸腔内淋巴结(21%,15/72)和非原发灶(17%,12/72)。帕博利珠单抗组和联合治疗组的最佳ARR分别为19.7%(15/76)和41.7%(30/72),OR=2.96,95%CI:1.42~6.20,P=0.0039;最佳ACR分别为43.4%(33/76)和65.3%(47/72),OR=2.51,95%CI:1.28~4.91,P=0.0071;PFS中位数分别为4.4(IQR:2.9~5.9)和9.0个月(IQR:6.8~11.2),HR=0.67,95%CI:0.45~0.99,P=0.045;OS中位数分别为8.7(IQR:6.4~11.0)和19.2个月(IQR:14.6~23.8),OR=0.67,95%CI:0.54~0.84,P=0.0004。在汇总分析中没有发现新的安全问题。解读帕博利珠单抗免疫疗法+放疗显著提高转移性NSCLC患者的应答和改善治疗结局。这些结果需要在三期临床试验中进行验证。陈大卫(翻译) 于金明(校对) Willemijn S M E Theelen Vivek Verma Brian P Hobbs Heike M U Peulen Joachim G J V Aerts Idris Bahce Anna Larissa N Niemeijer Joe Y Chang Patricia M de Groot Quynh-Nhu Nguyen Nathan I Comeaux George R Simon Ferdinandos Skoulidis Steven H Lin Kewen He Roshal Patel John Heymach Paul Baas James W Welsh 2021中华肿瘤防治杂志2021,28,24:49
2Football injuries of the ankle: A review of injury mechanisms, diagnosis and management显示文摘Football is the most popular sport worldwide and is associated with a high injury rate, most of which are the result of trauma from player contact. Ankle injuries are among the most commonly diagnosed injuries in the game. The result is reduced physical activity and endurance levels, lost game time, and considerable medical cost. Sports medicine professionals must employ the correct diagnostic tools and effective treatments and rehabilitation protocols to minimize the impact of these injuries on the player. This review examines the diagnosis, treatment, and postoperative rehabilitation for common football injuries of the ankle based on the clinical evidence provided in the current literature.Raymond J Walls Keir A Ross Ethan J Fraser Christopher W Hodgkins Niall A Smyth Christopher J Egan James Calder John G Kennedy 2016World Journal of Orthopedics2016,7,1:5
3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
4Scaffolds based therapy for osteochondral lesions of the talus:A systematic review显示文摘AIM To clarify the effectiveness of scaffold-based therapy for osteochondral lesions of the talus(OLT). METHODS A systematic search of MEDLINE and EMBASE databases was performed during August 2016 and updated in January 2017. Included studies were evaluated with regard to the level of evidence(LOE) and quality of evidence(QOE) using the Modified Coleman Methodology Score. Variable reporting outcome data, clinical outcomes, and the percentage of patients who returned to sport at previous level were also evaluated. RESULTS Twenty-eight studies for a total of 897 ankles were included; 96% were either LOE Ⅲ or Ⅳ. Studies were designated as either of poor or fair quality. There were 30 treatment groups reporting six different scaffold repair techniques: 13 matrix-induced autologous chondrocyte transplantation(MACT), nine bone marrow derived cell transplantation(BMDCT), four autologous matrixinduced chondrogeneis(AMIC), and four studies of other techniques. The categories of general demographics(93%) and patient-reported outcome data(85%) were well reported. Study design(73%), imaging data(73%), clinical variables(49%), and patient history(30%) were also included. The weighted mean American Orthopaedic Foot and Ankle Society(AOFAS) score at final follow-up was: 86.7 in MACT, 88.2 in BMDCT, and 82.3 in AMIC. Eight studies reported that a weighted mean of 68.3% ofpatients returned to a previous level of sport activity. CONCLUSION Scaffold-based therapy for OLT may produce favorable clinical outcomes, but low LOE, poor QOE, and variability of the data have confounded the effectiveness of this treatment.Yoshiharu Shimozono Youichi Yasui Andrew W Ross Wataru Miyamoto John G Kennedy 2017World Journal of Orthopedics2017,8,10:4

72009年南极冰穹A的双色天光背景统计和分析显示文摘天光背景是天文台址的一个重要指标。利用2009年位于南极冰穹A的CSTAR望远镜两个波段的观测数据,对南极冰穹A的天光背景进行了统计和分析。结果表明约74%的g波段天光背景的ADU值小于每像素100/s;90.5%的r波段的天光背景的ADU值小于每像素100/s。在不考虑大气消光的情况下,定标后的结果为2009年冰穹A的观测数据中天光背景亮度的中值:g波段为19.9 mag/arcsec2,r波段为20.1 mag/arcsec2。宗伟凯 付建宁 牛家树 Ashley Michael C B 宫雪非 Lawrence J S 刘强 Luong-Van Daniel Pennypacker C R Storey John W V 王灵芝 王力帆 杨惠根 袁祥岩 York Donald G 朱镇熹 2014天文研究与技术2014,11,1:2
