| 1 | 激光剥蚀信号在线平滑和去汞装置:原位微区铅同位素准确分析利器显示文摘激光原位微区分析可在微观尺度上完成样品的元素定量分析或同位素组成测定,为研究成岩、成矿物质来源和追踪地壳与地幔演化历史提供了独特的观察视野。但是,激光剥蚀等离子体质谱的一些缺陷阻碍了地质样品的高精度、高空间分辨率分析,比如:剥蚀池的位置效应、低剥蚀速率下信号波动影响、激光剥蚀脉动式信号导致的光谱螺纹效应、高频激光剥蚀造成的元素分馏效应等。为此,一些学者设计了不同规格和样式的激光剥蚀信号平滑装置来克服这些问题。但是,这些信号平滑装置普遍还存在气体吹扫时间过长和降低激光剥蚀信号灵敏度等问题。因此,研制新型的信号平滑装置对改善LA—ICP—MS的数据质量具有重要的意义。 | Hu Z Zhang W Liu Y Gao S Li M Zong K Chen H Hu S 刘勇胜 | 2015 | 矿物岩石地球化学通报2015，34，4： | 114 |

| 4 | 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 |
| 5 | Overexpression of ADAM9 in non-small cell lung cancer correlates with brain metastasis显示文摘The 'a disintegrin and metalloprotease' (ADAM) family contributes to regulation of the cell-cell and cell-matrix interactions that are critical determinants of malignancy. To determine the relationship between metastasis and ADAM proteins, we compared the mRNA levels of ADAM9,-10,-12,-15, and-17 in sublines of an EBC-1 lung cancer cell line that were highly metastatic to either brain or bone. ADAM9 mRNA levels were significantly higher in highly brain-metastatic sublines than in the parent or highly bonemetastalic sublines. To elucidate the role ofADAM9 in brain metastasis, we stably transfected A549 and EBC-1 cells with a fulllength ADAM9 expression vector. Compared with mock-transfectants, ADAM9 overexpression resulted in increased invasive capacity | Shintani Y Higashiyama S Ohta M Hirabayashi H Yamamoto S Yoshimasu T Matsuda H Matsuura N | 2004 | 中国神经肿瘤杂志2004，2，2： | 36 |

| 15 | Clinical value of rapid urine trypsinogen-2 test strip, urinary trypsinogen activation peptide, and serum and urinary activation peptide of carboxypeptidase B in acute pancreatitis显示文摘AIM: To assess the usefulness of urinary trypsinogen-2 test strip, urinary trypsinogen activation peptide (TAP),and serum and urine concentrations of the activation peptide of carboxypeptidase B (CAPAP) in the diagnosisof acute pancreatitis.METHODS: Patients with acute abdominal pain and hospitalized within 24 h after the onset of symptoms were prospectively studied. Urinary trypsinogen-2 was considered positive when a clear blue line was observed (detection limit 50 μg/L). Urinary TAP was measured using a quantitative solid-phase ELISA, and serum and urinary CAPAP by a radioimmunoassay method.RESULTS: Acute abdominal pain was due to acute pancreatitis in 50 patients and turned out to be extrapancreatic in origin in 22 patients. Patients with acute pancreatitis showed significantly higher median levels of serum and urinary CAPAP levels, as well as amylase and lipase than extrapancreatic controls. Median TAP levels were similar in both groups. The urinary trypsinogen-2 test strip was positive in 68% of patients with acute pancreatitis and 13.6% in extrapancreatic controls (P<0.01). Urinary CAPAP was the most reliable test for the diagnosis of acute pancreatitis (sensitivity 66.7%, specificity 95.5%, positive and negative predictive values 96.6% and 56.7%, respectively), with a 14.6 positive likelihood ratio for a cut-off value of 2.32 nmol/L.CONCLUSION: In patients with acute abdominal pain,hospitalized within 24 h of symptom onset, CAPAP in serum and urine was a reliable diagnostic marker of acute pancreatitis. Urinary trypsinogen-2 test strip showed a clinical value similar to amylase and lipase.Urinary TAP was not a useful screening test for the diagnosis of acute pancreatitis. | Jesús Sáez Juan Martínez Celia Trigo José Sánchez-Payá Luis Compay Raquel Laveda Pilar Grió Cristina García Miguel Pérez-Mateo | 2005 | World Journal of Gastroenterology2005，11，46： | 21 |
| 16 | Protective effect of naringenin on acetic acid-induced ulcerative colitis in rats显示文摘AIM:To evaluate the ameliorative effect of naringenin(NG)during ulcerative colitis(UC)in rats.METHODS:Rats were treated with three different doses(25,50 and 100 mg/kg per day)of NG and a single dose of mesalazine(MES,300 mg/kg per day)for seven days prior to ulcerative colitis induction by4%acetic acid(AA).Twenty four hours after AA rectal administration,animals were scarified and the colonic tissues were dissected.Colonic mucus content was estimated using Alcian blue dye binding technique.In colon tissues,levels of total glutathione sulphadryls(T-GSH),non-protein sulphadryls(NP-SH)and thiobarbituric acid reactive substances(TBARS)were evaluated.The activities of the antioxidant enzymes,catalase(CAT)and superoxide dismutase(SOD)were measured.Concentrations of nucleic acids(DNA and RNA)and total protein were also estimated in colon tissues.Colonic levels of tumor necrosis factor-(TNF-),interleukin-1(IL-1),interleukin-6(IL-6),prostaglandin E2(PGE2)and nitric oxide(NO)were estimated.In cross section of colitis tissue the histopathological changes were observed.RESULTS:Colonic mucus content was decreased in AA compared to controls(587.09±65.59 mg/kg vs941.78±68.41 mg/kg,P<0.001).AA administration markedly reduced T-GSH(5.25±0.37 nmol/L vs 3.04±0.24 nmol/L,P<0.01),NP-SH(3.16±0.04 nmol/L vs 2.16±0.30 nmol/L,P<0.01),CAT(6.77±0.40 U/mg vs 3.04±0.2 U/mg,P<0.01)and SOD(3.10±0.11U/mg vs 1.77±0.18 U/mg,P<0.01)while TBARS,TNF-,IL-1,IL-6,PGE2 and NO levels(15.09±3.84nmol/L vs 59.90±16.34 nmol/L,P<0.01;113.56±1.91 pg/mg vs 134.24±4.77 pg/mg,P<0.01;209.20±36.38 pg/mg vs 422.19±31.47 pg/mg,P<0.01;250.83±25.09 pg/mg vs 638.58±115.9 pg/mg,P<0.01;248.19±36.98 pg/mg vs 541.74±58.34 pg/mg,P<0.01 and 81.26±2.98 mmol/g vs 101.90±10.73 mmol/g,P<0.001)were increased in colon of rats with UC compared controls respectively.Naringenin supplementation,significantly and dose dependently increased the colonic mucus content.The elevated TBARS levels were significantly decreased(39.35±5.86nmol/L,P<0.05;26.74±3.17 nmol/L,P<0.01 nmol/L and 17.74±2.69 nmol/L,P<0.01)compared to AA(59.90±16.34 nmol/L)group while the decreased levels of T-GSH and NP-SH and activities of CAT and SOD found increased by NG treatments in dose dependent manner.The decreased values of nucleic acids and total protein in AA group were also significantly(P<0.01)increased in all three NG supplemented groupsrespectively.NG pretreatment inhibited the TNF-levels(123.76±3.76 pg/mg,122.62±3.41 pg/mg and121.51±2.61 pg/mg vs 134.24±4.78 pg/mg,P<0.05)compared to AA group,respectively.Interleukins,IL-1 and IL-6 levels were also decreased in NG50+AA(314.37±16.31 pg/mg and 292.58±23.68 pg/mg,P<0.05)and NG100+AA(416.72±49.62 pg/mg and 407.96±43.87 pg/mg,P<0.05)when compared to AA(352.46±8.58 pg/mg and 638.58±115.98pg/mg)group.Similar decrease(P<0.05)was seen in PGE2and NO values when compared to AA group.The group pretreated with MES,as a reference drug,showed significant(P<0.01)protection against the changes induced in colon tissue by AA administration respectively.CONCLUSION:In present study,NG produced antioxidant and anti-inflammatory effects demonstrating protective effect in inflammatory bowel disease. | Salim S Al-Rejaie Hatem M Abuohashish Maher M Al-Enazi Abdullah H Al-Assaf Mihir Y Parmar Mohammed M Ahmed | 2013 | World Journal of Gastroenterology2013，19，34： | 20 |

| 19 | 预期寿命估计对脊柱转移瘤手术选择与预后预测的临床意义显示文摘背景与目的:目前,临床上对脊柱转移瘤患者是否采取手术治疗以及如何选择手术仍然存在较大的争议。预期寿命的估计是手术选择的决定因素之一。本研究旨在评价Tokuhashi和Tomita评分系统这两种常用的预期寿命估计方法对硬膜外脊柱转移瘤患者手术选择与预后预测的临床价值。方法:对2001年1月至2004年4月丹麦奥胡斯大学医院脊柱外科中心收治的169例硬膜外脊柱转移瘤入组患者,术前用Tokuhashi与Tomita评分系统进行评分以及估计预期寿命,并结合Tomita脊柱肿瘤分型,选择实施手术分级治疗。术后6个月、12个月以及24个月分别进行前瞻性随访观察。对在预期寿命为“3个月内死亡”、“6个月内死亡”以及“12个月内死亡”的患者通过Tokuhashi与Tomita评分系统绘制受试者作业特征曲线(receiveroperatingcharacteristiccurves,ROC曲线),比较两个评分系统对预期寿命估计的准确性。同时采用Kaplan-Meier生存曲线分析法,计算Tokuhashi和Tomita评分系统各分数段患者术后的实际平均生存时间。结果:预期寿命分别为“3个月内死亡”、“6个月内死亡”以及“12个月内死亡”的病例ROC曲线分析显示,Tomita评分系统与Tokuhashi评分系统之间的差异均无显著性(各组P值分别为0.16、0.47与0.38)。Kaplan-Meier生存曲线分析显示,Tomita评分系统在4~7分之间对预后估计过高,Tokuhashi评分系统在0~8分之间对预后估计过低。结论:Tokuhashi和Tomita评分系统均可成功地预测脊柱转移瘤患者术后预后的情况。Tokuhashi评分系统可较为准确地预测生存期较短的患者,从而避免对这类患者做不必要的大手术。 | 邹学农 Anders Grejs 李海声 Kristian Hφy Ebbe S Hansen Cody Bünger | 2006 | 癌症2006，25，11： | 18 |
| 20 | Advances in endoscopic retrograde cholangiopancreatography for the treatment of cholangiocarcinoma显示文摘Cholangiocarcinoma(CCA) is a malignancy of the bileducts that carries high morbidity and mortality. Patients with CCA typically present with obstructive jaundice, and associated complications of CCA include cholangitis and biliary sepsis. Endoscopic retrograde cholangiopancreatography(ERCP) is a valuable treatment modality for patients with CCA, as it enables internal drainage of blocked bile ducts and hepatic segments by using plastic or metal stents. While there remains debate as to if bilateral(or multi-segmental) hepatic drainage is required and/or superior to unilateral drainage, the underlying tenant of draining any persistently opacified bile ducts is paramount to good ERCP practice and good clinical outcomes. Endoscopic therapy for malignant biliary strictures from CCA has advanced to include ablative therapies via ERCP-directed photodynamic therapy(PDT) or radiofrequency ablation(RFA). While ERCP techniques cannot cure CCA, advancements in the field of ERCP have enabled us to improve upon the quality of life of patients with inoperable and incurable disease. ERCP-directed PDT has been used in lieu of brachytherapy to provide neoadjuvant local tumor control in patients with CCA who are awaiting liver transplantation. Lastly, mounting evidence suggests that palliative ERCP-directed PDT, and probably ERCPdirected RFA as well, offer a survival advantage to patients with this difficult-to-treat malignancy. | Dushant S Uppal Andrew Y Wang | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，7： | 18 |
