| 3 | 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 |
| 4 | Draining Tangjiashan Barrier Lake after Wenchuan Earthquake and the flood propagation after the dam break显示文摘Tangjiashan Barrier Lake is one of the largest barrier lakes caused by the Wenchuan Earthquake. Its risk analysis, emergency plan and effect of the emergency plan are introduced in this paper. The dam height of Tangjiashan Barrier Dam is about 105 m, and the reservoir storage capacity is 3.2×108 m3. When the dam broke the flood peak were estimated to be larger than 48000 m3/s, which might cause a enormous disaster to the downstream cities and residents. A discharge channel with 13 m deep and 8 m wide was drug, so that the water may flow out of the lake before the dam breaks. As a result, the drainage and risk mitigation project are successful. During the drainage process, the flood peak was about 6500 m3/s, and about 1.6×108 m3 of water was drained off and the residual reservoir capacity was only 8.97×107 m3. A new channel with average width 100 m was formed, which can bear floods of 200 years frequency. The successful experience and the collected data can be used to deal with the similar natural disasters in future. | LIU Ning1, ZHANG JianXin2, LIN Wei3, CHENG WuYI4 & CHEN ZuYu5 1 Ministry of Water Resources of the People’s Republic of China, Beijing 100053, China 2 Bureau of Hydrology of the Ministry of Water Resources of the People’s Republic of China, Beijing 100053, China 3 Sichuan Hydrographic and Water Resources Survey Bureau Chengdu 610031, China 4 HydroChina Chengdu Engineering Corporation, Chengdu 610072, China 5 China Institute of Water Resources and Hydropower Research, Beijing 100044, China | 2009 | Science China(Technological Sciences)2009，52，4： | 29 |
| 5 | Early intrajejunal nutrition: bacterial translocation and gut barrier function of severe acute pancreatitis in dogs显示文摘Objective: To evaluate the effect of early intrajejunalnutrition in attenuating bacterial and/or endotoxintranslocation and improving gut barrier function ofsevere acute pancreatitis (SAP) in dogs.Methods: 15 dogs were divided into parenteral nutrition(PN) group(7 dogs)and early intrajejunal nutrition(EIN) group(8). EIN was delivered nutrients via a nee-dle jejunostomy catheter feeding at 48h after operation.SAP model was induced by injecting 1 ml/kg of com-bined solution of 5% sodium taurocholate and 8000-10000 BAEE units trypsin/ml into the pancreas via thepancreatic duct. Systemic blood samples were ob-tained before and 1, 3, 5, 7 d following SAP, and culturedby aerobic as well as anaerobic bacterial growth. Systemicplasma and portal vein endotoxin levels were quantifiedby the chromogenic limulus amebocyte lysate (LAL)technique. Portal vein blood and specimens of tissuefrom the mesenteriolum and mesocolon lymph nodes,lung, pulmonary portal lymph nodes, pancreatitis tissueand periopancreas tissue were adopted before the experi-ment was finished. Aliquots of the homogenata were cul-tured as blood mentioned above to determine the magnitudeof the bacteria DNA, protein and the villi, the thickness ofmucosa, and the whole bowel wall of the ileum and trans-verse colon were measured.Results: The study showed that the levels of systemicplasma endotoxin and the magnitude of bacterialtranslocation to the portal and systemic blood and dis-tant organ were reduced significantly in the EINgroup as compared with the TPN group. The contentsof protein and DNA, the height of villi, the thicknessof mucosa and whole bowel wall of the ileum andtransverse colon in the EIN group were higher thanthose in the PN group.Conclusion: Our results suggested that EIN is safe andeffective to be adopted by intrajejunal delivery of nu-trients in SAP, decreases the occurrence of gut bacterialtranslocation, and improves the gut barrier function. | Huan-Long Qin Zhen-Dong Su Qi Gao Qing-Tian Lin From the Department of Surgery, Shanghai Sixth People’s Hospital, Shanghai, 200233, China | 2002 | Hepatobiliary & Pancreatic Diseases International2002，1，1： | 20 |

| 14 | Effects of suppressing glucose transporter-1 by an antisense oligodeoxynucleotide on the growth of human hepatocellular carcinoma cells显示文摘BACKGROUND:The glucose transporter-1(Glut-1),a key ratelimiting factor in the transport and metabolism of glucose in cancer cells,is over-expressed in many human cancer cells and this overexpression is correlated with poor biological behavior. The increased levels of Glut-1 expression in hepatocellular carcinoma(HCC)cells functionally affect tumorigenicity.This study was undertaken to investigate effects of suppressing Glut-1 by an antisense oligodeoxynucleotide(AS-ODN)on the growth of human hepatocellular carcinoma(HepG-2)cells. METHODS:We used AS-ODN targeting against the Glut-1 gene in a HepG-2 cell line.There were four experimental groups: empty pcDNA3.1 vector(mock transfection),pcDNA3.1-anti-Glut(+),pcDNA3.1-Glut(+),and non-transfected HepG-2 cells. The Glut-1 mRNA expression was detected by RT-PCR and the Glut-1 protein expression by Western blotting after cell culture, and the glucose uptake was detected after glucose stimulation in each group. RESULTS:Compared with non-transfected HepG-2 or Glut-1 pcDNA3.1,a down-regulation of Glut-1 mRNA in HepG-2 cells transfected with anti-Glut-1 pcDNA3.1 was noted(P<0.05).Glut-1 protein in HepG-2 cells transfected with Glut-1 AS-ODN was decreased compared with non-transfected HepG-2,Glut-1 pcDNA3.1,or empty vectors. Glucose uptake by the HepG-2 cells transfected with AS-ODN was decreased at 1 hour after glucose stimulation.CONCLUSIONS:The application of Glut-1 AS-ODN can down-regulate the expression of Glut-1 at mRNA and protein,and inhibit glucose uptake partially in HepG-2 cells.The Glut-1 gene maybe a potential therapeutic target for HCC. | Tian-Qi Liu,Jun Fan,Lin Zhou and Shu-Sen Zheng Key Laboratory of Combined Multi-organ Trans-plantation,Ministry of Public Health Key Laboratory of Organ Trans-plantation,Zhejiang Province and Division of Hepatobiliary and Pancreatic Surgery,Department of Surgery State Key Laboratory for Diagnosis and Treatment of Infectious Disease,First Affiliated Hospital,Zhejiang University School of Medicine,Hangzhou 310003,China Department of Hepatobiliary Surgery,the People’s Hospital of Guangxi Zhuang Autonomous Region, Nanning 530021,China | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，1： | 9 |
| 15 | Performing colonoscopy in elderly and very elderly patients:Risks,costs and benefits显示文摘Many diagnostic and screening colonoscopies are performed on very elderly patients.Although colonoscopic yield increases with age,the potential benefits in such patients decrease because of shorter life expectancy and more frequent comorbidities.Colonoscopy in very elderly patients carries a greater risk of complications and morbidity than in younger patients,and is associated with lower completion rates and higher likelihood of poor bowel preparation.Thus,screening colonoscopy in very elderly patients should be performed only after careful consideration of potential benefits,risks and patient preferences.On the other hand,diagnostic and therapeutic colonoscopy are more likely to benefit even very elderly patients,and in most cases should be performed if indicated. | Otto S Lin | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，6： | 8 |
