目的:分析非上呼吸消化道来源的结外NK/T细胞淋巴瘤(non-upper aerodigestive tract extranodal NK/T-cell lymphoma,NUAT-ENKTCL)的不良预后因素。方法:回顾性分析郑州大学第一附属医院2011年1月至2015年12月收治的20例NUAT-NKTCL患者... 目的:分析非上呼吸消化道来源的结外NK/T细胞淋巴瘤(non-upper aerodigestive tract extranodal NK/T-cell lymphoma,NUAT-ENKTCL)的不良预后因素。方法:回顾性分析郑州大学第一附属医院2011年1月至2015年12月收治的20例NUAT-NKTCL患者临床资料,采用Kaplan-Meier法进行生存分析,应用Log-Rank法检验对EBER表达、年龄、性别、乳酸脱氢酶(lactic dehydrogenase,LDH)水平和治疗前外周血EBV-DNA拷贝数等进行单因素分析。结果:20例患者中,男女比为13∶7。中位年龄为39(12~66)岁,其中≥60岁3例(15%),<60岁17例(85%)。Ann Arbor分期:Ⅰ、Ⅱ期8例(40%),Ⅲ、Ⅳ期12例(60%)。LDH水平升高12例(60%)。治疗前外周血EBV-DNA拷贝数增加11例(55%)。病变组织中EBER(+)13例(65%)。患者截至随访时间死亡4例,生存16例,中位总生存期(median overall survival,mOS)为15.4个月,中位无进展生存期(median progression free survival,mPFS)为8个月。完全缓解(complete response,CR)11例(55%),部分缓解(partial response,PR)5例(25%),客观缓解率(objective response rate,ORR)为80%。单因素分析显示年龄与预后呈显著相关性。结论:EBER的表达并不影响NUAT-ENKTCL患者的预后,年龄≥60岁患者预后较差。 展开更多

Objective:This study aimed to evaluate the safety,efficacy,and feasibility of the rituximab,fotemustine,pemetrexed,and dexamethasone(R-FPD)regimen followed by whole-brain radiotherapy(WBRT)for patients with primary central nervous system lymphoma(PCNSL).Methods:A prospective,single-center phase II clinical trial was conducted.Patients with PCNSL newly diagnosed at the First Affiliated Hospital of Zhengzhou University between July 2018 and July 2020 were studied.The R-FPD regimen consisted of rituximab(375 mg/m2 i.v.on D0),fotemustine(100 mg/m2 i.v.on D1),pemetrexed(600 mg/m2 i.v.on D1),and dexamethasone(40 mg i.v.on D1-5).Patients 60 years or younger who showed a complete response(CR)were treated with 23.4 Gy of WBRT after the end of chemotherapy;those older than 60 years with CR were treated with a wait-and-see approach;and those who did not show CR after the 4th cycle of chemotherapy were given salvage WBRT 30 Gy+local tumor field irradiation up to 45 Gy,regardless of age.Results:A total of 30 patients were included.After 2 cycles,the objective response rate(ORR)was 96.5%(28/29,1 CR,27 PR,0 SD,and 1 PD).After 4 cycles,the ORR was 73.1%(19/26,11 CR,8 PR,4 SD,and 3 PD).After WBRT,the ORR was 90.9%(10/11,7 CR,3 PR,and 1 SD).The grade III and IV toxicity responses were mainly leukopenia(20.0%),thrombocytopenia(23.3%),and anemia(10.0%).Conclusions:Fotemustine-based therapy in combination with rituximab chemotherapy followed by WBRT can improve outcomes,providing ORR benefits and favorable tolerability in patients newly diagnosed with PCNSL. 展开更多

Non-precious metal single-atom catalysts(NPM-SACs)with unique electronic structures and coordination environments have gained much attention in electrocatalysis owing to their low cost,high atomic utilization,and high performance.NPM-SACs on carbon support(NPM-SACs/CS)are promising because of the carbon substrate with a large surface area,excellent electrical conductivity,and high chemical stability.This review provides an overview of recent developments in NPM-SACs/CS for the electrocatalytic field.First,the state-of-the-art synthesis methods and advanced characterization techniques of NPM-SACs/CS are discussed in detail.Then,the structural adjustment strategy of NPM-SACs/CS for optimizing electrocatalytic performance is introduced concisely.Furthermore,we provide a comprehensive summary of recent advances in developing NPM-SACs/CS for important electrochemical reactions,including carbon dioxide reduction reaction,hydrogen evolution reaction,oxygen evolution reaction,oxygen reduction reaction,and nitrogen reduction reaction.In the end,the existing challenges and future opportunities of NPM-SACs/CS in the electrocatalytic field are highlighted. 展开更多
