3Upregulation of vimentin and aberrant expression of E-cadherin /beta-catenin complex in oral squamous cell carcinomas:correlation with the clinicopathological features and patient outcome显示文摘Oral squamous cell carcinoma is a challenging oncology problem.A reliable biomarker for metastasis or high-risk prognosis in oral cancer patients remains undefined.Using quantitative immunohistochemistry,we examined the expression of vimentin,E-cadherin,and beta-catenin in 83 oral squamous cell carcinoma patients,and the relationships between the expression of these markers and specific clinicopathological features were analysed.The high expression of vimentin was observed in 23 of 43(53%) tumours from patients who eventually developed a recurrent tumour and was associated with recurrence and death(P < 0.001 and < 0.001,respectively).The decreased expression of E-cadherin was observed in 36 of 43(84%) tumours from patients who eventually developed a recurrent tumour and was also associated with recurrence and death(P < 0.001 and < 0.001,respectively).Although no correlation between beta-catenin expression in whole-tumour sections and clinicopathological features was observed,decreased beta-catenin expression at the tumour invasive front was closely associated with recurrence and death(P=0.002 and 0.002,respectively).The expression of vimentin and that of E-cadherin were associated with survival and were independent prognostic factors in univariate and multivariate analyses.Our data show that the overexpression of vimentin was closely associated with recurrence and death in oral squamous cell carcinoma patients.The combination of the upregulation of vimentin and aberrant expression of E-cadherin/beta-catenin complexes at the tumour invasive front may provide a useful prognostic marker in oral squamous cell carcinoma.Liu,LK Jiang,XY Zhou,XX Wang,DM Song,XL Jiang,HB Nanjing Med Univ,Coll Stomatol,Dept Oral Pathol,Nanjing 210029,Jiangsu,Peoples R China Nanjing Med Univ,Inst Stomatol,Dept Oral Pathol,Nanjing 210029,Jiangsu,Peoples R China Nanjing Med Univ,Coll Stomatol,Dept Oral & Maxillofacial Surg,Nanjing 210029,Jiangsu,Peoples R China 2010南京医科大学学报(自然科学版)2010,30,5:25
4Suppression of P-gp induced multiple drug resistance in a drug resistant gastric cancer cell line by overexpression of Fas显示文摘AIM To observe the drug sensitizing effect andrelated mechanisms of fas gene transduction onhuman drug-resistant gastric cancer cellSGC7901/VCR(resistant to Vincristine).METHODS The cell cycle alteration wasobserved by FACS.The sensitivity of gastriccancer cells to apoptosis was determined by invitro apoptosis assay.The drug sensitization ofcells to several anti-tumor drugs was observedby MTT assay.Immunochemical method wasused to show expression of P-gp and Topo Ⅱ ingastric cancer cells.RESULTS Comparing to SGC7901 and pBK-SGC7901/VCR,fas-SGC7901/VCR showeddecreasing G2 cells and increasing S cells,theG2 phase fraction of pBK-SGC7901/VCR wasabout 3.0 times that of fas-SGC7901/VCR,but Sphase fraction of fas-SGC7901/VCR was about1.9 times that of pBK-SGC7901/VCR,indicatingS phase arrest of fas-SGC7901/VCR.FACS alsosuggested apoptosis of fas-SGC7901/VCR,fas-SGC7901/VCR was more sensitive to apoptosisinducing agent VM-26 than pBK-SGC7901/VCR.MTT assay showed increased sensitization offas-SGC7901/VCR to DDP,MMC and 5-FU,butsame sensitization to VCR according to pBK-SGC7901/VCR.SGC7901,pBK-SGC7901/ VCRand fas-SGC7901/VCR had positively stainedTopo Ⅱ equally.P-gp staining in pBK- SGC7901/VCR was stronger than in SG07901,but there was little staining of P-gp in fas.SGC7901/VCR.CONCLUSION fas gene transduction couldreverse the MDR of human drug-resistant gastriccancer cell SGC7901/VCR to a degree,possiblybecause of higher sensitization to apoptosis anddecreased expression of P-gp.Yin F Shi YQ Zhao WP Xiao B Miao JY Fan DM 2000World Journal of Gastroenterology2000,6,5:24
5Down-regulation of Hsp90 could change cell cycle distribution and increase drug sensitivity of tumor cells显示文摘:AIM To construct Hsp90 antisense RNAeukaryotic expression vector, transfect it intoSGC7901 and SGC7901/VCR of MDR-type humangastric cancer cell lines, HCC7402 of humanhepatic cancer and Eel09 of human esophagealcancer cell lines, and to study the cell cycledistribution of the gene transected cells andtheir response to chemotherapeutic drugs.METHODS A I .03kb cDNA sequence of Hsp90Pwas obtained from the primary plasmid phHsp90by EcoR 1 and BamH I nuclease digestion andwas cloned to the EcoR 1 and BamH 1 site ofthe pcDNA by T4DNA ligase and an antisenseorientation of Hsp900 expression vector wasconstructed. The constructs were transfectedwith lipofectamine and positive clones wereselected with G418. The expression of RNA wasdetermined with dot blotting and RNaseprotection assay, and the expression of Hsp90protein determined with Western blot. Cell cycledistribution of the transfectants was analyzedwith flow cytometry, and the drug sensitivity ofthe transfectants to adriamycin (ADR ),vincrinstine (VCR ), mitomycin (MMC ) andcyclophosphamide (CTX ) with MTT andintracellular drug concentration of thetransfectants was determined with flowcytometry.RESULTS In EcoR 1 and BamH I restrictionanalysis, the size and the direction of the clonedsequence of Hsp900 remained what had beendesigned and the gene constructs were namedpcDNA-Hsp90. AH^SGC7901, AH^SGC7901/ VCR,AH-HCC7402 and AH-Eel09 cell clones allexpressed Hsp90 anti--sense RNA. Theexpression of Hsp90 was down--regulated in AHSGC7901, AH--SGC7901/ VCR, AH-HCC7402 andAH--Eel09 cell clones. Cell cycle distribution waschanged differently. In AH-SGC7901/ VCR andAH-Ec109 cells, G, phase cells were increased; Sphase and G, phase cells were decreased ascompared with their parental cell lines. In AHSGC7901 cell, G, phase cells were decreased, Qphase cells increased and S phase cells were notchanged, and in AH-HCC7402 cells G,, S and qphase cells remained unchanged as comparedwith their parental cell lines. The sensitivity ofAH--SGC7901, AH--SGC7901/ VCR, AH-HCC7402 andAH-Ec109 to chemotherapeutic drugs, thesensitivity ot AH--SGC7901/ VCR to ADR, VCR,MMC and CTX the sensitivity of AH-HCC7402 toADR and VCR, and the sensitivity of Eel09 toADR, VCR and CTX all increased as comparedwith their parental cell lines. The meanfluorescence intensity of ADR in AH--SGC7901,AH-SGC7901/ VCR, AH--HCC7402 and AH-Ec109was also significantly elevated (P< 0. 05).CONCLUSION Down-regulation of HsP90 couldchange cell cycle distribution and increase thedrug sensitivity of tumor cells.Liu XL Xiao B Yu ZC Guo JC Zhao QC Xu L Shi YQ Fan DM 1999World Journal of Gastroenterology1999,5,3:21

10Coronary artery anomalies overview: The normal and the abnormal显示文摘The aim of this review is to give a comprehensive and concise overview of coronary embryology and normal coronary anatomy, describe common variants of normal and summarize typical patterns of anomalous coronary artery anatomy. Extensive iconography supports the text, with particular attention to images obtained in vivo using non-invasive imaging. We have divided this article into three groups, according to their frequency in the general population: Normal, normal variant and anomaly. Although congenital coronary artery anomalies are relatively uncommon, they are the second most common cause of sudden cardiac death among young athletes and therefore warrant detailed review. Based on the functional relevance of each abnormality, coronary artery anomalies can be classified as anomalies with obligatory ischemia, without ischemia or with exceptional ischemia. The clinical symptoms may include chest pain, dyspnea, palpitations, syncope, cardiomyopathy, arrhythmia, myocardial infarction and sudden cardiac death. Moreover, it is important to also identify variants and anomalies without clinical relevance in their own right as complications during surgery or angioplasty can occur.Adriana DM Villa Eva Sammut Arjun Nair Ronak Rajani Rodolfo Bonamini Amedeo Chiribiri 2016World Journal of Radiology2016,8,6:14
11阿米福汀对单次肺照射的保护作用及TGF-β1活性的影响显示文摘目的用大鼠放射性肺损伤模式评价阿米福汀对单次肺照射的放射性肺损伤保护作用和对TGFβ1活性变化的影响。方法34只150~160g的Fish344雌性大鼠随机进入照射加药(11只)、单纯照射(11只)、单用药(6只)和正常对照(6只)实验组。用4MVX射线单次28Gy照射右全肺,照射前30min腹腔内注射阿米福汀150mg/kg。每2周观测呼吸频率和血浆转化生长因子(TGFβ1)水平,在6个月后终止观察。肺组织进行羟脯胺酸、胶原蛋白含量、总TGFβ1与活性TGFβ1水平、TGFβ1蛋白表达和巨噬细胞量等检测。结果单纯照射组呼吸频率于第8周发生改变、达(185±13)次/min,3只因呼吸困难终止观察,7只有胸腔积液;照射加药组于第14周开始增加,仅为(125±5)次/min,无呼吸困难和胸腔积液发生。单纯照射组的肺组织结构消失纤维化,照射加药组也有纤维化,但保持大部分肺泡结构。血浆TGFβ1水平呈双峰改变,单纯照射组12周时为(3.2±0.5)ng/ml,较照射加药组(1.3±0.3)ng/ml明显增高(P=0.004);肺组织活性TGFβ1与总TGFβ1含量之比分别为3.9%±0.2%与3.1%±0.2%,单纯照射明显高于照射加药组(P<0.05)。结论阿米福汀不仅能增加肺组织对放射性损伤的耐受,同时也能减少TGFβ1的含量与表达,也许同时能减少TGFβ1的活性表达。冯勤付 Vujaskovic Z Brizel DM Anscher MS 2004中华放射肿瘤学杂志2004,13,3:12
