| 1 | 帕博利珠单抗联合以铂类为基础的化疗治疗非小细胞肺癌合并稳定性脑转移患者的结局:KEYNOTE-021、-189和-407研究的汇总分析显示文摘背景与目的此项探索性分析回顾评价了晚期非小细胞肺癌(non-small cell lung cancer,NSCLC)患者的结局,旨在确定基线时合并脑转移是否会影响一线应用帕博利珠单抗联合化疗(pembrolizumab plus chemotherapy,PC)比对单用化疗的疗效。患者和方法对KEYNOTE-021队列G(非鳞癌)、KEYNOTE-189(非鳞癌)和KEYNOTE-407(鳞癌)三项研究晚期NSCLC患者的数据进行汇总分析。患者接受含铂两药化疗和/或35个周期帕博利珠单抗治疗(每3周200 mg)。所有研究均纳入了经治或初治的稳定性脑转移患者(KEYNOTE-189与KEYNOTE-407研究纳入初治脑转移患者)。经治的脑转移患者已处于病情稳定的状态≥2周(KEYNOTE-021队列G患者≥4周),无新发或脑转移病灶扩大的证据且入组前至少3天以上未使用激素。初治的无症状脑转移患者需定期接受脑部影像学检查。结果共纳入1298例患者,其中171例有基线脑转移,1127例无脑转移。两组的中位随访时间(范围)在数据截止时分别为10.9(0.1-35.1)个月和11.0(0.1-34.9)个月。合并脑转移和无脑转移患者的总生存期[0.48(95%CI:0.32-0.70)和0.63(95%CI:0.53-0.75)]和无进展生存期[0.44(95%CI:0.31-0.62)和0.55(95%CI:0.48-0.63)]的风险比(PC/化疗)相似。合并脑转移的患者中,PC组和单用化疗组患者的中位总生存期分别为18.8个月和7.6个月,中位无进展生存期分别为6.9个月和4.1个月。无论是否合并脑转移,PC组患者的客观缓解率都高于单用化疗组,且缓解持续时间有显著延长。合并脑转移的患者中,PC组与单用化疗组的治疗相关不良事件发生率分别为88.2%和82.8%;而无脑转移的患者中,两组治疗相关不良事件的发生率分别为94.5%和90.6%。结论无论是否合并脑转移,与单用化疗相比,帕博利珠单抗联合以铂类为基础的组织学特异性化疗可改善所有PD-L1亚组的临床结局,其中包括PD-L1肿瘤比例评分<1%的患者,并且在晚期NSCLC患者中安全性良好。该方案是晚期NSCLC初治患者的标准方案,并可用于合并稳定性脑转移的患者。 | 周清(翻译校对) Steven F Powell Delvys Rodríguez-Abreu Corey J Langer Ali Tafreshi Luis Paz-Ares Hans-Georg Kopp Jeronimo Rodríguez-Cid Dariusz M Kowalski Ying Cheng Takayasu Kurata Mark M Awad Jinaxin Lin Bin Zhao M Catherine Pietanza Bilal Piperdi Marina C Garassino | 2022 | 中国肺癌杂志2022，25，1： | 6 |
| 2 | Immunogenetic factors driving formation of ultralong VH CDR3 in Bos taurus antibodies显示文摘The antibody repertoire of Bos taurus is characterized by a subset of variable heavy(VH)chain regions with ultralong third complementarity determining regions(CDR3)which,compared to other species,can provide a potent response to challenging antigens like HIV env.These unusual CDR3 can range to over seventy highly diverse amino acids in length and form uniqueβ-ribbon‘stalk’and disulfide bonded‘knob’structures,far from the typical antigen binding site.The genetic components and processes for forming these unusual cattle antibody VH CDR3 are not well understood.Here we analyze sequences of Bos taurus antibody VH domains and find that the subset with ultralong CDR3 exclusively uses a single variable gene,IGHV1-7(VHBUL)rearranged to the longest diversity gene,IGHD8-2.An eight nucleotide duplication at the 3′end of IGHV1-7 encodes a longer V-region producing an extended Fβ-strand that contributes to the stalk in a rearranged CDR3.A low amino acid variability was observed in CDR1 and CDR2,suggesting that antigen binding for this subset most likely only depends on the CDR3.Importantly a novel,potentially AID mediated,deletional diversification mechanism of the B.taurus VH ultralong CDR3 knob was discovered,in which interior codons of the IGHD8-2 region are removed while maintaining integral structural components of the knob and descending strand of the stalk in place.These deletions serve to further diversify cysteine positions,and thus disulfide bonded loops.Hence,both germline and somatic genetic factors and processes appear to be involved in diversification of this structurally unusual cattle VH ultralong CDR3 repertoire. | Thaddeus C Deiss Melissa Vadnais Feng Wang Patricia L Chen Ali Torkamani Waithaka Mwangi Marie-Paule Lefranc Michael F Criscitiello Vaughn V Smider | 2019 | Cellular & Molecular Immunology2019，16，1： | 4 |
| 3 | Drainage vs. non-drainage after cholecystectomy for acute cholecystitis:a retrospective study显示文摘Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence,this study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis.A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital,Abha,Saudi Arabia,was conducted from April 2010 to April 2012.Data were extracted from hospital case files.Preoperative data included clinical presentation,routine investigations and liver function tests.Operative data included excessive adhesions,bleeding,bile leak,and drain insertion.Complicated cases such as pericholecystic collections,mucocele and empyema were also reported.Patients who needed therapeutic drainage were excluded.Postoperative data included hospital stay,volume of drained fluid,time of drain removal,and drain site problems.The study included 103 patients allocated into two groups;group A(n = 38) for patients with operative drain insertion and group B(n = 65) for patients without drain insertion.The number of patients with preoperative diagnosis of acute non-complicated cholecystitis was significantly greater in group B(80%) than group A(36.8%)(P < 0.001).Operative time was significantly longer in group A.All patients who were converted from laparoscopic to open cholecystectomy were in group A.Multivariate analysis revealed that hospital stay was significantly(P < 0.001) longer in patients with preoperative complications.There was no added benefit for prophylactic drain insertion after cholecystectomy for acute calculous cholecystitis in non-complicated or in complicated cases. | Mohammed A Bawahab Walid M Abd El Maksoud Saeed A Alsareii Fahad S Al Amri Hala F Ali Abdul Rahman Nimeri Abdul Rahman M Al Amri Adel A Assiri Mohammed I Abdul Aziz | 2014 | The Journal of Biomedical Research2014，28，3： | 3 |

| 5 | Prevalence of plasmid mediated bla_(TEM-1) and bla_(CTX-M-15) type extended spectrum beta-lactamases in patients with sepsis显示文摘Objective:To characterize the bacterial pathogens in patients having gram negative septicaemia. Further,to evaluate the antimicrobial resistance and underlying molecular mechanisms in these strains.Methods:A total number of 70 cases of gram negative sepsis were included in this prospective,open labeled,observational study.Standard methods for isolation and identification of bacteria were used.Antimicrobial susceptibility and ESBL testing was performed by the standard disc diffusion method.PCR amplification was performed to identify blaCTX-M,blaSHVand blaTEM type ESBLs.Conjugation experiments were performed to show resistant marker transfer. Results:The most prevalent isolates Escherichia coli(E.coli) 58.6%,Klebsiella Spp.32.9%and Pseudomonas 8.6%,were resistant to most of the antimicrobials including cefazolin,ceftriaxone, cefuroxime,ampicillin and co-trimoxazole but sensitive to imipenem and meropenem.ESBL and MBL production was seen 7.3%and 12.2%of E.coli isolates respectively.Three isoaltes were found to have blaCTX-M-15 and two of them also showed blaTEM-1 type enxyme.Whereas, none of them showed blaSHV.Conjugation experiments using J-53 cells confirmed these resistant markers as plasmid mediated.Conclusions:This work highlights the molecular epidemiology of escalating antimicrobial resistance and likely switch over of blaCTX-M-15 type extended spectrum beta-lactamases by blaTEM type ESBLs in India.Further,the antimicrobial resistance by horizontal gene transfer was predominant among Enterobacteraceae in the community setting. | Shahzad F Haque Saeedut-Z Ali Mohammed TP Asad U Khan | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，2： | 2 |
| 6 | Rare presentation of primary (AL) amyloidosis as gastrointestinal hemorrhage without systemic involvement显示文摘We are reporting a rare case of a patient with primary(AL) amyloidosis presenting with an acute non-varicealupper gastrointestinal hemorrhage in the absence ofother systemic involvement. The case report involves a58-year-old woman with significant cardiac history andhereditary blood disorder who came in complaining ofabdominal pain and coffee-ground emesis for two days.Computed tomography(CT) scan of the abdomen andpelvis with contrast revealed segmental wall thickeningof the proximal jejunum with hyperdense, heterog-enous luminal content. Similar findings were evident inthe left lower small bowel region, suspicious for smallbowel hematoma and the possibility of intraluminalclots. Esophagogastroduodenoscopy performed postresuscitation showed punctate, erythematous lesionsthroughout the stomach as well as regions of smallbowel mucosa that appeared scalloped, ulcerated, andhemorrhaged on contact. Despite initial treatment for immunostain-positive focal cytomegalovirus gastritis, follow-up esophagogastroduodenoscopy after two months continued to demonstrate friable and irregular duodenal mucosa hinting at a different underlying etiol-ogy. Pathology reports from analyses of biopsy samples highlighted infiltration and expansion of the lamina pro-pria and submucosa. Subsequent staining with congo red/crystal violet and appropriate subtyping established the diagnosis of AL(kappa)-type amyloidosis. The sig-nificance of this case lies in the fact that our patient did not have the typically seen diagnostic systemic involvements-namely of heart and kidneys-usually seen in primary(AL) amyloidosis patients. It was the persis-tent endoscopic findings and biopsy results which gave clues to the physicians regarding the possibility of an abnormal protein-deposition entity. | Mohammad F Ali Anik Patel Stephanie Muller David Friedel | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，4： | 2 |
| 7 | Software Project Management Approaches for Global Software Development: A Systematic Mapping Study显示文摘Global Software Development(GSD) is a well established field of software engineering with the benefits of a global environment. Software Project Management(SPM) plays a key role in the success of GSD. As a result, the need has arisen to study and evaluate the downsides of SPM for GSD, to thereby pave the way for the development of new methods, techniques, and tools with which to tackle them. This paper aims to identify and classify research on SPM approaches for GSD that are available in the literature, to identify their current weaknesses and strengths, and to analyze their applications in industry. We performed a Systematic Mapping Study(SMS) based on six classification criteria. Eighty-four papers were selected and analyzed. The results indicate that interest in SPM for GSD has been increasing since 2006. As a class of approaches, the most frequently reported methods(40%) are those used for coordination, planning, and monitoring, along with estimation techniques that can be used to better match a distributed project. SPM for GSD requires further investigation by researchers and practitioners, particularly with respect to cost and time estimations. These findings will help overcome the challenges that must to be considered in future SPM research for GSD, especially regarding collaboration and time-zone differences. | Manal El Bajta Ali Idri Joaquín Nicolás Ros José Luis Fernández-Alemán Juan Manuel Carrillo de Gea Félix García Ambrosio Toval | 2018 | Tsinghua Science and Technology2018，23，6： | 2 |
