1基于IMRT时代的第八版AJCC/UICC鼻咽癌临床分期建议显示文摘目的准确的分期系统对癌症的治疗至关重要。随着癌症分期和治疗方法的演变,需要不断评价分期的适用性和改进性。方法基于第7版AJCC/UICC分期回顾性分析香港和中国大陆2个肿瘤中心收治的1609例接受调强放射治疗的首诊无转移鼻咽癌患者临床资料,所有患者治疗前均行核磁共振分期评估。结果无其他T3、T4期解剖结构受侵患者中,伴有咀嚼肌间隙(翼内肌和/或翼外肌)侵犯、椎前肌侵犯及咽旁间隙侵犯的三组患者之间0s相近。伴广泛软组织(上述侵犯结构以外的软组织)受侵患者OS与伴有颅内侵犯或颅神经侵犯相似。仅2%患者锁骨上窝以上淋巴结转移者直径〉6cm,其0s率与下颈淋巴结转移者类似。用下颈(环状软骨尾侧缘水平以下)代替锁骨上窝并不影响N分期之间的风险差异性。采用推荐的T、N分期,T。N。、T。N,期0s相近。结论经AJCC/UICC分期筹备委员会审阅后,建议第8版分期应将翼内肌/翼外肌从T。降到T:期,增加椎前肌为L期,用下颈取代锁骨上窝,将淋巴结最大直径〉6cm合并归为N,期,将T。、N,期统一归为Ⅳ。期。这些改变不仅使得相邻分期间风险差异性更好,而且使得临床实践性与全球适用性之间达到最佳平衡。潘建基 Wai Tong Ng 宗井凤 Lucy L.K.Chan Brian O' Sullivan 林少俊 Henry C.K.Sze 陈韵彬 Horace C.W.Choi 郭巧娟 Wai Kuen Kan 肖友平 Xu Wei Quynh Thu Le Christine M.Glastonbury A.Dimtrios Colevas Randal S.Weber Jatin P.Shah Anne W.M.Lee 2016中华放射肿瘤学杂志2016,25,3:65
2Role of liver transplantation in the management of hepatoblastoma in the pediatric population显示文摘Hepatoblastoma(HB) is the most common primary liver tumor in children and accounts for two-thirds of all malignant liver neoplasms in the pediatric population. For patients with advanced HB(unresectable or unresponsive to chemotherapy), combined treatment with chemotherapy and liver transplantation is an excellent option. The etiology of HB is mostly obscure because of its extreme rarity although some inherited syndromes and very low birth weight have been associated with it. The prognosis for children with HB has significantly improved in the past three decades thanks to advancements in chemotherapy, surgical resection and postoperative care. In 2002 a surgical staging system called pretreatment extent of disease(PRETEXT) was designed to allow a universal, multidisciplinary approach to patients with HB. Between one-third to two-thirds of patients initially present with unresectable tumors or distant metastases, but up to 85% of these tumors become operable after neoadjuvant chemotherapy. Patients with PRETEXT categories 1, 2, and some 3 are referred for neoadjuvant chemotherapy followed by surgical resection with the goal of complete tumor removal. Classic treatments regimens include a combination of cisplatin, fluorouracil, and vincristine or cisplatin and doxorubicin. Liver transplantation is the only treatment option for unresectable HB. In 2010 the pediatric end-stage liver disease, a pediatric-specific scoring system that determines a patient's ranking on the liver transplant list, began to award additional 'exception' points for patients with HB. We analyzed the Standard Transplant Analysis and Research dataset to assess the impact of changes in exception point criteria for HB on outcomes after liver transplantation at Texas Children's Hospital in Houston, Texas. We found that patients who were listed for transplantation with current HB exception criteria experienced a shorter waitlist time but survival was similar between the two eras.Saira Khaderi Jacfranz Guiteau Ronald T Cotton Christine O'Mahony Abbas Rana John A Goss 2014World Journal of Transplantation2014,4,4:23
3中国上市公司业绩与总经理变更分析显示文摘本文研究了上市公司业绩与总经理的强制性变更和正常性变更的关系。研究结果显示,强制性总经理变更作为最极端的约束手段能够约束业绩差的总经理;差的业绩并不是导致总经理变更的原因。无论是强制性还是正常性总经理变更都对公司的业绩没有显著的影响,也就是说,总经理变更,特别是强制性总经理变更不能达到促进公司业绩提高的目的。皮莉莉 Julian Lowe Christine O'Connor 2005甘肃社会科学2005,,3:9
4Multimodality imaging of ovarian cystic lesions: Review with an imaging based algorithmic approach显示文摘Ovarian cystic masses include a spectrum of benign, borderline and high grade malignant neoplasms. Imaging plays a crucial role in characterization and pretreatment planning of incidentally detected or suspected adnexal masses, as diagnosis of ovarian malignancy at an early stage is correlated with a better prognosis. Knowledge of differential diagnosis, imaging features, management trends and an algorithmic approach of such lesions is important for optimal clinical management. This article illustrates a multi-modality approach in the diagnosis of a spectrum of ovarian cystic masses and also proposes an algorithmic approach for the diagnosis of these lesions.Ashish P Wasnik Christine O Menias Joel F Platt Usha R Lalchandani Deepak G Bedi Khaled M Elsayes 2013World Journal of Radiology2013,5,3:7
5Bifunctional chimeric SuperCD suicide gene -YCD: YUPRT fusion is highly effective in a rat hepatoma model显示文摘AIM: To investigate the effects of catalytically superior gene-directed enzyme prodrug therapy systems on a rat hepatoma model.METHODS: To increase hepatoma cell chemosensitivity for the prodrug 5-fluorocytosine (5-FC), we generated a chimeric bifunctional SuperCD suicide gene, a fusion of the yeast cytosine deaminase (YCD) and the yeast uracil phosphoribosyltransferase (YUPRT) gene.RESULTS: In vitro stably transduced Morris rat hepatoma cells (MH) expressing the bifunctional SuperCD suicide gene (MH SuperCD) showed a clearly marked enhancement in cell killing when incubated with 5-FC as compared with MH ceils stably expressing YCD solely (MH YCD) or the cytosine deaminase gene of bacterial origin(MH BCD), respectively. In vivo, MH SuperCD tumors implanted both subcutaneously as well as orthotopically into the livers of syngeneic ACI rats demonstrated significant tumor regressions (P<0.01) under both high dose as well as low dose systemic 5-FC application,whereas MH tumors without transgene expression (MH naive) showed rapid progression. For the first time, an order of in vivo suicide gene effectiveness (SuperCD>>YCD > > BCD > > > negative control) was defi ned as a result of a directin vivo comparison of all three suicide genes.CONCLUSION: Bifunctional SuperCD suicide gene expression is highly effective in a rat hepatoma model,thereby significantly improving both the therapeutic index and the efficacy of hepatocellular carcinoma killing by fluorocytosine.Florian Graepler Marie-Luise Lemken Wolfgang A Wybranietz Ulrike Schmidt Irina Smirnow Christine D GroB Martin Spiegel Andrea Schenk Schenk Hansj(o|¨)rg Graf Ulrike A Lauer Reinhard Vonthein Michael Gregor Sorin Armeanu Michael Bitzer Ulrich M.Lauer 2005World Journal of Gastroenterology2005,11,44:2

7Monitoring dioxins and PCBs in eggs as sensitive indicators for environmental pollution and global contaminated sites and recommendations for reducing and controlling releases and exposure显示文摘This review compiles information on PCDD/F-and PCB-contaminated eggs from 20 years of global egg monitoring around emission sources in four continents conducted by the International Pollutants Elimination Network(IPEN)and Arnika as well as a compilation of data from scientific literature.IPEN monitored 127 pooled egg samples including samples from 113 chicken flocks at potential PCDD/F-and PCB-contaminated sites around priority sources listed in the Stockholm Convention(e.g.waste incinerators,metal industries,cement plants,and open burning).99(88%)of pooled egg samples were above the EU maximum limits for PCDD/Fs(2.5 pg PCDD/F-TEQ/g fat)or the sum of PCDD/Fs and dioxinlike PCBs(5 pg PCDD/F-PCB-TEQ/g fat).Children consuming such eggs exceed the tolerable weekly intake(TWI).This demonstrates that close to 90%of these areas were not safe for the production of free-range eggs.Sixteen out of the 113 egg samples(14%)were contaminated above 50 pg TEQ/g fat and exceeded the EU maximum limit more than 10 times.From the 26 pooled egg samples around incinerators 24(92%)exceeded the limit with a mean of 43.1 pg TEQ/g fat(2.6e234 pg TEQ/g).All 21 egg samples around metal industries(4.4e112.6 pg TEQ/g fat)were above limits with mean concentration of 26.0 pg TEQ/g fat.Also all 7 egg samples measured at e-waste recycling sites were above limits(mean 308 pg TEQ/g fat).In 58(51%)pooled egg samples the PCB-TEQ was above 5 pg TEQ/g fat exceeding the EU maximum limit with dioxin-like PCBs alone.This highlights the role of commercial PCBs for global contamination with dioxin-like compounds.It was discovered that around metal industries,shredder plants,open burning sites of e-waste and dump sites,a high share of contamination was caused by dl-PCBs.This clearly shows severe PCB release from the end-of-life management of PCB-containing equipment in developing countries.Also highly contaminated eggs were found at many sites where plastic was incinerated.The highest contaminated egg sample ever measured came from an e-waste site in Ghana and had 856 pg TEQ/g fat plus 300 pg TEQ from brominated dioxins(PBDD/Fs).Other extreme PCDD/F contaminations of eggs were found at a chlor-alkali site(514 pg TEQ/g fat),Agent Orange contaminated areas in Vietnam(490,249 and 246 pg TEQ/g fat)and e-waste sites(568 and 520 pg TEQ/g fat).Where DR CALUX®bioassay revealed higher TEQ compared to measured PCDD/F-PCB-TEQ in IPEN studies,polybrominated PBDD/F were also measured and detected up to 300 pg TEQ/g fat at e-waste sites.One positive outcome from the IPEN studies is that all 10 pooled supermarket eggs in developing countries were below regulatory limit.Policy recommendations are made including:a systematic assessment of areas around PCDD/Fs and PCBs sources;measures for reduction of exposures of populations;urgent control of emission sources including PCB equipment,the open burning of plastic,and the use of plastic as fuel in boilers/incinerators in developing countries without air pollution control.Furthermore,soil limits need to be re-assessed and lowered for free-range poultry.Jindrich Petrlik Lee Bell Joe DiGangi Serge Molly Allo'o Allo'o Gilbert Kuepouo Griffins Ochieng Ochola Valeriya Grechko Nikola Jelinek Jitka Strakova Martin Skalsky Yuyun Ismawati Drwiega Jonathan N.Hogarh Eric Akortia Sam Adu-Kumi Akarapon Teebthaisong Maria Carcamo Bjorn Beeler Peter Behnisch Claudia Baitinger Christine Herold Roland Weber 2022Emerging Contaminants2022,8,1:2
