| 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 |
| 2 | Developmental dysplasia of the hip in the newborn: A systematic review显示文摘Developmental dysplasia of the hip(DDH) denotes a wide spectrum of conditions ranging from subtle acetabular dysplasia to irreducible hip dislocations. Clinical diagnostic tests complement ultrasound imaging in allowing diagnosis, classification and monitoring of this condition. Classification systems relate to the alpha and beta angles in addition to the dynamic coverage index(DCI). Screening programmes for DDH show considerable geographic variation; certain risk factors have been identified which necessitate ultrasound assessment of the newborn. The treatment of DDH has undergone significant evolution, but the current gold standard is still the Pavlik harness. Duration of Pavlik harness treatment has been reported to range from 3 to 9.3 mo. The beta angle, DCI and the superior/lateral femoral head displacement can be assessed via ultrasound to estimate the likelihood of success. Success rates of between 7% and 99% have been reported when using the harness to treat DDH. Avascular necrosis remains the most devastating complication of harness usage with a reported rate of between 0% and 28%. Alternative non-surgical treatment methods used for DDH include devices proposed by LeD amany, Frejka, Lorenz and Ortolani. The Rosen splint and Wagner stocking have also been used for DDH treatment. Surgical treatment for DDH comprises open reduction alongside a combination of femoral or pelvic osteotomies. Femoral osteotomies are carried out in cases of excessive anteversion or valgus deformity of the femoral neck. The two principal pelvic osteotomies most commonly performed are the Salter osteotomy and Pemberton acetabuloplasty. Serious surgical complications include epiphyseal damage, sciatic nerve damage and femoral neck fracture. | Vivek Gulati Kelechi Eseonu Junaid Sayani Nizar Ismail Chika Uzoigwe Muhammed Zaki Choudhury Pooja Gulati Adeel Aqil Saket Tibrewal | 2013 | World Journal of Orthopedics2013，4，2： | 29 |

| 5 | Multi-modality imaging review of congenital abnormalities of kidney and upper urinary tract显示文摘Congenital abnormalities of the kidney and urinary tract(CAKUT) include a wide range of abnormalities ranging from asymptomatic ectopic kidneys to life threatening renal agenesis(bilateral). Many of them are detected in the antenatal or immediate postnatal with a significant proportion identified in the adult population with varying degree of severity. CAKUT can be classified on embryological basis in to abnormalities in the renal parenchymal development, aberrant embryonic migration and abnormalities of the collecting system. Renal parenchymal abnormalities include multi cystic dysplastic kidneys, renal hypoplasia, number(agenesis or supernumerary), shape and cystic renal diseases. Aberrant embryonic migration encompasses abnormal location and fusion anomalies. Collecting system abnormalities include duplex kidneys and Pelvi ureteric junction obstruction. Ultrasonography(US) is typically the first imaging performed as it is easily available, noninvasive and radiation free used both antenatally and postnatally. Computed tomography(CT) and magnetic resonance imaging(MRI) are useful to confirm the ultrasound detected abnormality, detection of complex malformations, demonstration of collecting system and vascular anatomy and more importantly for early detection of complications like renal calculi, infection and malignancies. As CAKUT are one of the leading causes of end stage renal disease, it is important for the radiologists to be familiar with the varying imaging appearances of CAKUT on US, CT and MRI, thereby helping in prompt diagnosis and optimal management. | Subramaniyan Ramanathan Devendra Kumar Maneesh Khanna Mahmoud Al Heidous Adnan Sheikh Vivek Virmani Yegu Palaniappan | 2016 | World Journal of Radiology2016，8，2： | 13 |

| 7 | Endosonography in the diagnosis and management of pancreatic cysts显示文摘Rapid advances in radiologic technology and increased cross-sectional imaging have led to a sharp rise in incidental discoveries of pancreatic cystic lesions. These cystic lesions include non-neoplastic cysts with no risk of malignancy, neoplastic non-mucinous serous cystadenomas with little or no risk of malignancy, as well as neoplastic mucinous cysts and solid pseudopapillary neoplasms both with varying riskof malignancy. Accurate diagnosis is imperative as management is guided by symptoms and risk of malignancy. Endoscopic ultrasound(EUS) allows high resolution evaluation of cyst morphology and precise guidance for fine needle aspiration(FNA) of cyst fluid for cytological, chemical and molecular analysis. Initially, clinical evaluation and radiologic imaging, preferably with magnetic resonance imaging of the pancreas and magnetic resonance cholangiopancreatography, are performed. In asymptomatic patients where diagnosis is unclear and malignant risk is indeterminate, EUSFNA should be used to confirm the presence or absence of high-risk features, differentiate mucinous from non-mucinous lesions, and diagnose malignancy. After analyzing the cyst fluid for viscosity, cyst fluid carcinoembryonic antigen, amylase, and cyst wall cytology should be obtained. DNA analysis may add useful information in diagnosing mucinous cysts when the previous studies are indeterminate. New molecular biomarkers are being investigated to improve diagnostic capabilities and management decisions in these challenging cystic lesions. Current guidelines recommend surgical pancreatic resection as the standard of care for symptomatic cysts and those with high-risk features associated with malignancy. EUSguided cyst ablation is a promising minimally invasive, relatively low-risk alternative to both surgery and surveillance. | Vivek Kadiyala Linda S Lee | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，3： | 12 |

| 9 | Gastroesophageal reflux disease and severe obesity:Fundoplication or bariatric surgery?显示文摘Increases in the prevalence of obesity and gastroesophageal reflux disease (GERD) have paralleled one another over the past decade, which suggests the possibility of a linkage between these two processes. In both instances, surgical therapy is recognized as the most effective treatment for severe, refractory disease. Current surgical therapies for severe obesity include (in descending frequency) Roux-en-Y gastric bypass, adjustable gastric banding, sleeve gastrectomy, and biliopancreatic diversion with duodenal switch, while fundoplication remains the mainstay for the treatment of severe GERD. In several large series, however, the outcomes and durability of fundoplication in the setting of severe obesity are not as good as those in patients who are not severely obese. As such, bariatric surgery has been suggested as a potential alternative treatment for these patients. This article reviews current concepts in the putative pathophysiological mechanisms by which obesity contributes to gastroesophageal reflux and their implications with regards to surgical therapy for GERD in the setting of severe obesity. | Vivek N Prachand John C Alverdy | 2010 | World Journal of Gastroenterology2010，16，30： | 10 |
| 10 | Combined treatment of non-small cell lung cancer using radiotherapy and immunotherapy: challenges and updates显示文摘The efficacy of immunotherapy for advanced non-small cell lung cancer(NSCLC)remains unsatisfactory,as the majority of patients either do not experience an objective response or acquire secondary resistance.As a result,several methods to enhance the systemic efficacy of immunotherapy have been investigated,including a large area of active research by combining immunotherapy with radiation therapy(RT).Given the rapidly burgeoning concept of combining immunotherapy and RT for increasing therapeutic benefit,we review the progress in this field thus far and explore further avenues for enhancing this combination.This review commences with a discussion of the only two existing randomized trials(and a pooled analysis)showing that the addition of RT to immunotherapy improves the abscopal response rate,progression-free survival,and overall survival in metastatic NSCLC patients.We then discussed factors and biomarkers that may be associated with a proportionally greater benefit to additional RT,such as low programmed cell death protein ligand 1(PD-L1)status,tumor mutational burden(TMB),and patient’s immune function.Next,the implementation of RT to overcome immunotherapy resistance is discussed,including a mechanistic discussion and methods with which these mechanisms could be exploited.Lastly,the emerging role of low-dose RT is discussed,which may help to overcome inhibitory signals in the tumor stroma that limit T-cell infiltration.Taken together,given the current state of this rapidly expanding realm,these futuristic strategies may be reflected upon to further enhance the efficacy of immunotherapy for a wider group of patients. | Shijie Shang Jie Liu Vivek Verma Meng Wu James Welsh Jinming Yu Dawei Chen | 2021 | Cancer Communications2021，41，11： | 10 |
| 11 | Current Status and Future Challenges of Weather Radar Polarimetry: Bridging the Gap between Radar Meteorology/Hydrology/Engineering and Numerical Weather Prediction显示文摘After decades of research and development, the WSR-88 D(NEXRAD) network in the United States was upgraded with dual-polarization capability, providing polarimetric radar data(PRD) that have the potential to improve weather observations,quantification, forecasting, and warnings. The weather radar networks in China and other countries are also being upgraded with dual-polarization capability. Now, with radar polarimetry technology having matured, and PRD available both nationally and globally, it is important to understand the current status and future challenges and opportunities. The potential impact of PRD has been limited by their oftentimes subjective and empirical use. More importantly, the community has not begun to regularly derive from PRD the state parameters, such as water mixing ratios and number concentrations, used in numerical weather prediction(NWP) models.In this review, we summarize the current status of weather radar polarimetry, discuss the issues and limitations of PRD usage, and explore potential approaches to more efficiently use PRD for quantitative precipitation estimation and forecasting based on statistical retrieval with physical constraints where prior information is used and observation error is included. This approach aligns the observation-based retrievals favored by the radar meteorology community with the model-based analysis of the NWP community. We also examine the challenges and opportunities of polarimetric phased array radar research and development for future weather observation. | Guifu ZHANG Vivek N.MAHALE Bryan J.PUTNAM Youcun QI Qing CAO ANDrew D.BYRD Petar BUKOVCIC Dusan S.ZRNIC Jidong GAO Ming XUE Youngsun JUNG Heather D.REEVES Pamela L.HEINSELMAN AlexANDer RYZHKOV Robert D.PALMER Pengfei ZHANG Mark WEBER Greg M.MCFARQUHAR Berrien MOORE III Yan ZHANG Jian ZHANG J.VIVEKANANDAN Yasser AL-RASHID Richard L.ICE Daniel S.BERKOWITZ Chong-chi TONG Caleb FULTON Richard J.DOVIAK | 2019 | Advances in Atmospheric Sciences2019，36，6： | 9 |

| 13 | Blumgart's technique of pancreaticojejunostomy: Analysis of safety and outcomes显示文摘Background: Blumgart's pancreaticojejunostomy(PJ) has been described with low pancreatic leak rates. This study aimed to evaluate our experience with this technique regarding the pancreatic leak and other perioperative outcomes. Methods: We performed a single-center retrospective analysis of a cohort of 81 patients who underwent pancreaticoduodenectomy in our department from January 2011 to February 2018. The primary endpoint was the occurrence of a clinically relevant postoperative pancreatic fistula(CR-POPF) and analysis of its risk factors. Results: The CR-POPF rate was 12.3%. Fistula risk score(FRS) was the only significant risk factor for the occurrence of overall POPF in multivariate analysis. However, none of the other factors including FRS was found to be significantly associated with CR-POPF risk. A strong positive correlation was found between the CR-POPF and the incidence of delayed gastric emptying, post-pancreatectomy hemorrhage and increased length of hospital stay. Conclusion: Blumgart's technique is a safe technique of pancreatico-enteric anastomosis with low rates of CR-POPF. CR-POPF with this technique is independent of most of the preoperative and intraoperative factors. Therefore, this technique can be used for all types of the pancreas with consistently good results. | Vishal Gupta Saket Kumar Vivek Gupta Pradeep Joshi Rahul Rahul Rakesh Kumar Yadav Amit Dangi Abhijit Chandra | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，2： | 8 |
| 14 | Antioxidant,lipid peroxidation inhibition and free radical scavenging efficacy of a diterpenoid compound sugiol isolated from Metasequoia glyptostroboides显示文摘Objective:To investigate the antioxidant enicacy of a biologically active dilerpenoid compound sugiol isolated from Metasequoia glyptostroboides(M.glyptostroboides)in various antioxidant models.Methods:An abietane type diterpenoid sugiol,isolated from ethyl acetate extract of M.glyptostroboides cones,was analyzed for its antioxidant efficacy as reducing power ability and lipid peroxidation inhibition as well as its ability to scavenge free radicals such as 1,1-diphenyl-2-picryl hydrazyl,nitric oxide,superoxide and hydroxyl radicals.Results:The sugiol showed significant and concentration-dependent antioxidant and free radical scavenging activities.Consequently,the sugiol exerted lipid peroxidation inhibitory effect by 76.3%as compared to a-tocopherol(80.13%)and butylaled hydroxyanisole(76.59%).In addition,the sugiol had significant scavenging activities of l,l-diphenyl-2-picryl hydrazyl,nitric oxide,superoxide and hydroxyl free radicals in a concentration-dependent manner by 78.83%,72.42%,72.99%and 85.04%,when compared to the standard compound ascorbic acid(81.69%,74.62%,73.00%and 73.79%)and a-tocopherol/butylated hydroxyanisole(84.09%,78.61%,74.45%and 70.02%),respectively.Conclusions:These findings justify the biological and traditional uses of M.glyptostroboides or its secondary metabolites as confirmed by its promising antioxidant efficacy. | Vivek K.Bajpai Ajay Sharma Sun Chul Kang Kwang-Hyun Baek | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，1： | 8 |

| 20 | Laparoscopic liver resection for benign and malignant liver tumors显示文摘BACKGROUND:Laparoscopic liver resection is one of the most complex procedures in hepatobiliary surgery.In the last two decades,laparoscopic liver surgery has emerged as an option at major academic institutions.The purpose of this study is to describe the initial experience of minimally invasive liver resections at a non-academic institution. METHODS:We retrospectively reviewed medical records of patients undergoing laparoscopic liver resections between June 2006 and December 2009 at our center.Indications, technical aspects,and outcomes of these patients are described. RESULTS:Laparoscopic liver resection was attempted in 28 patients.Of these,27 patients underwent laparoscopic liver resection(22 total laparoscopic and 5 hand assisted)and one needed conversion to open surgery.Twenty patients had a benign lesion and 8 had malignant lesions.Three patients had multiple lesions in different segments requiring separate resections.The lesions were located in segments Ⅱ-Ⅲ(n=18), Ⅳ(n=3),Ⅴ-Ⅵ(n=9),and VII(n=1).Tumor size ranged from 1.5 cm to 8.5 cm.The surgical procedures included left lateral sectionectomy(n=17),left hepatectomy(n=2),sectionectomy (n=8),and local resections(n=4).Median operative time was 110 minutes(range 55-210 minutes),and the median length of hospital stay was 2.5 days(range 1-7 days).There was no perioperative mortality.One patient developed hernia at the site of tumor extraction requiring repair at 3 months. CONCLUSIONS:Laparoscopic liver resections can be safely performed in selected patients with benign and malignant liver tumors.With increasing experience,laparoscopic liver resections are likely to become a favorable alternative to open resection. | Ashish Singhal Vivek Kohli Nazih | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，1： | 7 |
