1Refining pathological evaluation of neoadjuvant therapy for adenocarcinoma of the esophagus显示文摘AIM:To assess tumour regression grade(TRG)and lymph node downstaging to help define patients who benefit from neoadjuvant chemotherapy.METHODS:Two hundred and eighteen consecutive patients with adenocarcinoma of the esophagus or gastro-esophageal junction treated with surgery alone or neoadjuvant chemotherapy and surgery between 2005and 2011 at a single institution were reviewed.Triplet neoadjuvant chemotherapy consisting of platinum,fluoropyrimidine and anthracycline was considered for operable patients(World Health Organization performance status≤2)with clinical stage T2-4 N0-1.Response to neoadjuvant chemotherapy(NAC)was assessed using TRG,as described by Mandard et al.In addition lymph node downstaging was also assessed.Lymph node downstaging was defined by cN1 at diagnosis:assessed radiologically(computed tomography,positron emission tomography,endoscopic ultrasonography),then pathologically recorded as N0 after surgery;ypN0 if NAC given prior to surgery,or pN0if surgery alone.Patients were followed up for 5 years post surgery.Recurrence was defined radiologically,with or without pathological confirmation.An association was examined between t TRG and lymph node downstaging with disease free survival(DFS)and a comprehensive range of clinicopathological characteristics.RESULTS:Two hundred and eighteen patients underwent esophageal resection during the study interval with a mean follow up of 3 years(median follow up:2.552,95%CI:2.022-3.081).There was a 1.8%(n=4)inpatient mortality rate.One hundred and thirty-six(62.4%)patients received NAC,with 74.3%(n=101)of patients demonstrating some signs of pathological tumour regression(TRG 1-4)and 5.9%(n=8)having a complete pathological response.Forty four point one percent(n=60)had downstaging of their nodal disease(cN1 to ypN0),compared to only 15.9%(n=13)that underwent surgery alone(pre-operatively overstaged:cN1 to pN0),(P<0.0001).Response to NAC was associated with significantly increased DFS(mean DFS;TRG 1-2:5.1years,95%CI:4.6-5.6 vs TRG 3-5:2.8 years,95%CI:2.2-3.3,P<0.0001).Nodal down-staging conferred a significant DFS advantage for those patients with a poor primary tumour response to NAC(median DFS;TRG 3-5 and nodal down-staging:5.533 years,95%CI:3.558-7.531 vs TRG 3-5 and no nodal down-staging:1.114 years,95%CI:0.961-1.267,P<0.0001).CONCLUSION:Response to NAC in the primary tumour and in the lymph nodes are both independently associated with improved DFS.Fergus Noble Luke Nolan Adrian C Bateman James P Byrne Jamie J Kelly Ian S Bailey Donna M Sharland Charlotte N Rees Timothy J Iveson Tim J Underwood Andrew R Bateman 2013World Journal of Gastroenterology2013,19,48:4
2Reduced striatal volumes in Parkinson’s disease:a magnetic resonance imaging study显示文摘Background:The presence and extent of structural changes in the brain as a consequence of Parkinson’s disease(PD)is still poorly understood.Methods:High-resolution 3-tesla T1-weighted structural magnetic resonance images in sixty-five PD and 27 age-matched healthy control participants were examined.Putamen,caudate,and intracranial volumes were manually traced in the axial plane of 3D reconstructed images.Striatal nuclei volumes were normalized to intracranial volume for statistical comparison.Disease status was assessed using the Unified Parkinson’s Disease Rating Scale and Hoehn and Yahr scale.Cognitive status was assessed using global status tests and detailed neuropsychological testing.Results:Both caudate and putamen volumes were smaller in PD brains compared to controls after adjusting for age and gender.Caudate volumes were reduced by 11%(p=0.001)and putamen volumes by 8.1%(p=0.025).PD striatal volumes were not found to be significantly correlated with cognitive or motor decline.Conclusion:Small,but significant reductions in the volume of both the caudate and putamen occur in PD brains.These reductions are independent of the effects of age and gender,however the relation of these reductions to the functional loss of dopamine,which is characteristic of PD,remains unclear.Toni L Pitcher Tracy R Melzer Michael R MacAskill Charlotte F Graham Leslie Livingston Ross J Keenan Richard Watts John C Dalrymple-Alford Tim J Anderson 2012Translational Neurodegeneration2012,1,1:2
3基于一个大型随机试验预测稳定性心绞痛队列患者死亡、心肌梗死和卒中的危险评分显示文摘目的对需要抗心绞痛治疗并且左心室功能代偿症状稳定的心绞痛患者建立预测全因死亡、心肌梗死和导致致残性卒中的复合危险评分。设计大型多中心临床试验数据的多变量Cox回归分析。背景西欧、以色列、加拿大、澳大利亚和新西兰的心脏专科门诊患者。入选者7311例具有全部需要资料的患者被入选。主要结局的测量指标平均随访4.9年时间内所有原因的死亡、心肌梗死或者致残性卒中。结果1063例患者发生任何原因死亡或者持久性心肌梗死或者致残性卒中。这些复合终点的5年危险性在危险性最低的十分位患者为4%,而在危险性最高的十分位患者为35%。危险评分结合16项临床常规变量的降序排序是:年龄、左心室射血分数、吸烟、白细胞计数、糖尿病、随机血糖浓度、肌酐浓度、既往卒中病史、1周至少1次心绞痛发作、冠状动脉造影发现(如果能够获得)、降脂治疗、QT间期、收缩期血压≥150mmHg、抗心绞痛药物数量、陈旧性心肌梗死以及性别。把这个模型分别应用于任何原因所致的死亡、心肌梗死和卒中进行预测评估,所得的结果相似。危险评分似乎不能预测事件性质(39%的死亡、46%心肌梗死以及15%致残性卒中)或者冠状动脉造影或血管重建率(占29%的患者)。结论该危险评分对客观地决定稳定性心绞痛患者进一步治疗措施以减少重要预后事件发生是有帮助的。该危险评分同样可以用于将来的计划性试验。Tim C Clayton Stuart J Pocock Jacobus Lubsen Zoltán Vokó Bridget-Anne Kirwan Keith A A Fox Philip A Poole-Wilson 2006英国医学杂志中文版2006,9,1:2

15Serum outperforms plasma in small extracellular vesicle microRNA biomarker studies of adenocarcinoma of the esophagus显示文摘BACKGROUND Circulating microRNAs(miRNAs)are potential biomarkers for many diseases.However,they can originate from non-disease specific sources,such as blood cells,and compromise the investigations for miRNA biomarkers.While small extracellular vesicles(sEVs)have been suggested to provide a purer source of circulating miRNAs for biomarkers discovery,the most suitable blood sample for sEV miRNA biomarker studies has not been defined.AIM To compare the mi RNA profiles between matched serum and plasma s EV preparations to determine their suitability for biomarker studies.METHODS Matched serum and plasma samples were obtained from 10 healthy controls and10 patients with esophageal adenocarcinoma.s EV isolates were prepared from serum and plasma using Exo Quick TM and quantified using Nano Sight.RNA was extracted from s EV preparations with the mi RNeasy Serum/Plasma kit and profiled using the Taqman Openarray q PCR.The overall mi RNA content and theexpression of specific mi RNAs of reported vesicular and non-vesicular origins were compared between serum and plasma s EV preparations.The diagnostic performance of a previously identified multi-mi RNA biomarker panel for esophageal adenocarcinoma was also compared.RESULTS The overall mi RNA content was higher in plasma s EV preparations(480 mi RNAs)and contained 97.5%of the mi RNAs found in the serum s EV preparations(412 mi RNAs).The expression of commonly expressed mi RNAs was highly correlated(Spearman’s R=0.87,P<0.0001)between the plasma and serum s EV preparations,but was consistently higher in the plasma s EV preparations.Specific blood-cell mi RNAs(hsa-mi R-223-3 p,hsa-mi R-451 a,mi R-19 b-3 p,hsa-mi R-17-5 p,hsa-mi R-30 b-5 p,hsa-mi R-106 a-5 p,hsa-mi R-150-5 p and hsa-mi R-92 a-3 p)were expressed at 2.7 to 9.6 fold higher levels in the plasma s EV preparations compared to serum s EV preparations(P<0.05).In plasma s EV preparations,the percentage of protein-associated mi RNAs expressed at relatively higher levels(Ct 20-25)was greater than serum s EV preparations(50%vs 31%).While the percentage of vesicle-associated mi RNAs expressed at relatively higher levels was greater in the serum s EV preparations than plasma s EV preparations(70%vs 44%).A 5-mi RNA biomarker panel produced a higher cross validated accuracy for discriminating patients with esophageal adenocarcinoma from healthy controls using serum s EV preparations compared with plasma s EV preparations(AUROC 0.80 vs 0.54,P<0.05).CONCLUSION Although plasma s EV preparations contained more mi RNAs than serum s EV preparations,they also contained more mi RNAs from non-vesicle origins.Serum appears to be more suitable than plasma for s EV mi RNAs biomarkers studies.Karen Chiam George C Mayne Tingting Wang David I Watson Tanya S Irvine Tim Bright Lorelle T Smith Imogen A Ball Joanne M Bowen Dorothy M Keefe Sarah K Thompson Damian J Hussey 2020World Journal of Gastroenterology2020,26,20:1
