1Analyses of publicly available genomics resources define FGF-2-expressing bladder carcinomas as EMT-prone, proliferative tumors with low mutation rates and high expression of CTLA-4, PD-1 and PD-L1显示文摘Fibroblast growth factor 2(FGF-2)is overexpressed in a subset of invasive bladder carcinomas and its overexpression correlates with poor prognosis.Analyses of publicly available databases addressing the molecular mechanisms that may be responsible for the poor prognosis of these tumors,revealed that FGF-2 expression correlates positively with the expression of epithelial to mesenchymal transition(EMT)-promoting transcription factors and with changes in gene expression that are characteristic of EMT.The same analyses also revealed that FGF-2 correlates negatively with the expression,mutation and copy number variations of FGFR-3,all of which are associated with noninvasive bladder carcinomas.Finally,they showed that FGF-2 expression correlates with the expression of FGFR-1,the expression of the IIIc variant of FGFR-2 and with the expression of Akt3.The latter observation is significant because our earlier studies had shown that Akt3 regulates FGFR-2 alternative splicing,shifting the balance toward the IIIc relative to the IIIb FGFR-2 splice variant.As the IIIc variant is recognized by FGF-2,while the IIIb variant is not,we conclude that Akt3 may facilitate the FGF-2 response.FGF-2 is known to promote the expression of KDM2B,which functions in concert with EZH2 to repress the EZH2-targeting microRNA miR-101,activating a switch,which stably upregulates EZH2.The cancer genome atlas(TCGA)data showing a correlation between KDM2B and EZH2 expression and Oncomine data,showing a correlation between KDM2B and tumor progression,strongly support the role of the FGF-2/KDM2B/miR-101/EZH2 pathway in bladder cancer.These observations combined,suggest a model according to which FGF-2 induces EMT,cell proliferation and cancer stem cell self-renewal by coupling the Akt3 and KDM2B-controlled pathways outlined above,in bladder carcinomas.Further analyses of publicly available databases,revealed that FGF-2-expressing bladder carcinomas carry fewer genetic alterations and they tend to express high levels of CTLA-4,PD-1 and PD-L1,which suggests immune blockade by checkpoint activation.EMT,enhanced proliferation and immune checkpoint activation combined,may be responsible for the poor prognosis of FGF-2-expressing bladder carcinomas.Elizabeth A McNiel Philip N Tsichlis 2017Signal Transduction and Targeted Therapy2017,2,1:6
2妊娠期糖尿病对大鼠雌性子代缺血再灌注后心脏收缩功能的影响及其机制显示文摘目的利用大鼠模型探讨妊娠期糖尿病(GDM)对雌性子代心脏功能的影响及潜在机制。方法雌性野生型SD大鼠在妊娠中期给予腹腔注射链脲佐菌素(35 mg/kg)建立GDM模型(GDM组),另设正常对照组。分娩后,雌性F1子代饲养至24周,期间测定随机血糖、血压和心率,进行葡萄糖耐量试验、胰岛素耐量试验。构建心脏离体缺血再灌注(I/R)模型,Western blotting检测心脏蛋白激酶B(Akt)、腺苷酸激活蛋白激酶(AMPK)和乙酰辅酶A羧化酶(ACC)信号通路。结果 GDM组雌性F1子代离体I/R后心脏收缩功能显著低于正常对照组(P=0.048 6);Western blotting显示离体I/R后GDM组雌性F1子代大鼠心脏AMPK和ACC磷酸化水平显著低于正常对照组(P=0.005 6)。结论 GDM可引起子代雌性大鼠对心脏I/R损伤不耐受,这可能与其心脏AMPK磷酸化对I/R刺激反应迟钝有关。邹虹 姜小雪 王寒冰 袁雨 罗晓芳 谭彬 张华 Philip N Baker 童超 漆洪波 2016上海交通大学学报(医学版)2016,36,2:5
3Randomised controlled trial comparing modified Sano's and narrow band imaging international colorectal endoscopic classifications for colorectal lesions显示文摘AIM To assess the utility of modified Sano′s(MS) vs thenarrow band imaging international colorectal endoscopic(NICE) classification in differentiating colorectal polyps.METHODS Patients undergoing colonoscopy between 2013 and 2015 were enrolled in this trial.Based on the MS or the NICE classifications,patients were randomised for real-time endoscopic diagnosis.This was followed by biopsies,endoscopic or surgical resection.The endoscopic diagnosis was then compared to the final(blinded) histopathology.The primary endpoint was the sensitivity(Sn),specificity(Sp),positive predictive value(PPV) and negative predictive value(NPV) of differentiating neoplastic and non-neoplastic polyps(MSⅡ/Ⅱo/Ⅲa/Ⅲb vs I or NICE 1 vs 2/3).The secondary endpoints were 'endoscopic resectability'(MSⅡ/Ⅱo/Ⅲa vs Ⅰ/Ⅲb or NICE 2 vs 1/3),NPV for diminutive distal adenomas and prediction of post-polypectomy surveillance intervals.RESULTS A total of 348 patients were evaluated.The Sn,Sp,PPV and NPV in differentiating neoplastic polyps from non-neoplastic polyps were,98.9%,85.7%,98.2% and 90.9% for MS;and 99.1%,57.7%,95.4% and 88.2% for NICE,respectively.The area under the receiver operating characteristic curve(AUC) for MS was 0.92(95%CI:0.86-0.98);and AUC for NICE was 0.78(95%CI:0.69,0.88).The Sn,Sp,PPV and NPV in predicting 'endoscopic resectability' were 98.9%,86.1%,97.8% and 92.5% for MS;and 98.6%,66.7%,94.7% and 88.9% for NICE,respectively.The AUC for MS was 0.92(95%CI:0.87-0.98);and the AUC for NICE was 0.83(95%CI:0.75-0.90).The AUC values were statistically different for both comparisons(P = 0.0165 and P = 0.0420,respectively).The accuracy for diagnosis of sessile serrated adenoma/polyp(SSA/P) with high confidence utilizing MS classification was 93.2%.The differentiation of SSA/P from other lesions achieved Sp,Sn,PPV and NPV of 87.2%,91.5%,89.6% and 98.6%,respectively.The NPV for predicting adenomas in diminutive rectosigmoid polyps(n = 150) was 96.6% and 95% with MS and NICE respectively.The calculated accuracy of post-polypectomy surveillance for MS group was 98.2%(167 out of 170) and for NICE group was 92.1%(139 out of 151).CONCLUSION The MS classification outperformed the NICE classification in differentiating neoplastic polyps and predicting endoscopic resectability.Both classifications met ASGE PIVI thresholds.Leonardo Zorrón Cheng Tao Pu Kuan Loong Cheong Doreen Siew Ching Koay Sze Pheh Yeap Amanda Ovenden Mahima Raju Andrew Ruszkiewicz Philip W Chiu James Y Lau Rajvinder Singh 2018World Journal of Gastrointestinal Endoscopy2018,10,9:4

9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
