| 1 | Role of cyclooxygenase-2 in the carcinogenesis of gastrointestinal tract cancers: A review and report of personal experience显示文摘选择 cyclooxygenase (艇长)-2 禁止者(coxibs ) 作为反煽动性的药之一被开发避免 non-steroidal 的各种各样的副作用反煽动性的药(NSAID ) 。然而, coxibs 也有一个能力禁止各种各样的类型的肿瘤开发 NSAID 的一样的方法。用细胞线和动物模型的许多试验性的研究表明了一个能力阻止 COX-2 禁止者的肿瘤增长。在为息肉 chemoprevention 执行使随机化的研究以后,与家庭腺瘤息肉病( FAP )在病人学习,它证明有 celecoxib 的治疗, coxibs 之一,显著地减少了颜色的数字在 2000 的表面的息肉,美国食物药品管理局(食物及药品管理局)立即为 FAP 病人同意了临床的使用 celecoxib 。然而,某 coxibs 最近被报导包括心脏病和击增加严肃的心血管的事件的风险。在这篇文章,我们在胃肠道的致癌作用考察 COX-2 的一个角色,例如食管,胃和 colorectum,并且也为胃肠道肿瘤的 chemoprevention 分析 coxibs 的前景。 | Takashi Fujimura Tetsuo Ohta Katsunobu Oyama Tomoharu Miyashita Koichi Miwa | 2006 | World Journal of Gastroenterology2006，12，9： | 33 |
| 2 | Surgical anatomy of innervation of the gallbladder in humans and Suncus murinus with special reference to morphological understanding of gallstone formation after gastrectomy显示文摘瞄准:澄清人的胆囊的神经分布,与在胃切除术以后的胆石形成的词法理解的特殊参考。方法:肝,胆囊和包围结构在乙醇沉浸于茜素红 S 的 10 mg/L 答案在死尸染色周围神经(n = 10 ) 。在区域的神经分布完全在一台双目显微镜下面被把。同样,在 10 Suncus murinus 的一样的区域的神经分布(S。murinus ) 被检验采用整个山免疫组织化学。结果:胆囊的神经分布通过二条线路主要发生了。一个人从前面的肝的丛,神经分布沿着膀胱的动脉和管发生了。总是,这条线路通过了肝十二指肠系带。另外的线路从以后的肝的丛,神经分布沿着膀胱的管 vent 集合发生了。这条线路也通过了肝十二指肠系带欧洲粪金龟子突围。类似的结果在 S 被获得。murinus。结论:从经由膀胱的动脉或管的前面的肝的丛的线路为保存胆囊神经分布是关键的。淋巴节点解剖可以明确地在胃切除术以后在肝十二指肠系带影响胆石的发生。而且,从经由到胆囊的胆总管和膀胱的管的以后的肝的丛的线路不应该被不顾。丛的保藏可以在胃切除术以后稀释胆石形成的发生。 | Shuang-Qin Yi Tetsuo Ohta Akihiko Tsuchida Hayato Terayama Munekazu Naito Jun Li Heng-Xiao Wang Nozomi Yi Shigenori Tanaka Masahiro Itoh | 2007 | World Journal of Gastroenterology2007，13，14： | 19 |
| 3 | Enhancement patterns of pancreatic adenocarcinoma on conventional dynamic multi-detector row CT:Correlation with angiogenesis and fibrosis显示文摘AIM:To evaluate retrospectively the correlation between enhancement patterns on dynamic computed tomography (CT) and angiogenesis and fibrosis in pancreatic adenocarcinoma.METHODS: Twenty-three patients with pancreatic adenocarcinoma underwent dynamic CT and tumor resection. In addition to the absolute and relative enhanced value that was calculated by subtracting the attenuation value on pre-contrast from those on contrast-enhanced CT in each phase, we defined one parameter, 'tumor-aorta enhancement ratio', which was calculated by dividing enhancement of pancreatic cancer by enhancement of abdominal aorta in each phase. These enhancement patterns were correlated with the level of vascular endothelial growth factor (VEGF), microvessel density (MVD), and extent of fibrosis.RESULTS: The absolute enhanced value in the arterial phase correlated with the level of VEGF and MVD (P=0.047, P=0.001). The relative enhanced value in arterial phase and tumor-aorta enhancement ratio (arterial) correlated with MVD (P=0.003, P=0.022). Tumor-aorta enhancement ratio (arterial) correlated negatively with the extent of fibrosis (P=0.004). The tumors with greater MVD and higher expression of VEGF tended to show high enhancement in the arterial dominant phase. On the other hand, the tumors with a larger amount of fibrosis showed a negative correlation with the grade of enhancement during the arterial phase.CONCLUSION: Enhancement patterns on dynamic CT correlated with angiogenesis and may be modified by the extent of fibrosis. | Yuki Hattori Toshifumi Gabata Osamu Matsui Kentaro Mochizuki Hirohisa Kitagawa Masato Kayahara Tetsuo Ohta Yasuni Nakanuma | 2009 | World Journal of Gastroenterology2009，15，25： | 15 |
| 4 | Characterization of CD133^+ parenchymal cells in the liver:Histology and culture显示文摘AIM:To reveal the characteristics of CD133+ cells in the liver.METHODS:This study examined the histological characteristics of CD133+ cells in non-neoplastic and neoplastic liver tissues by immunostaining,and also analyzed the biological characteristics of CD133+ cells derived from human hepatocellular carcinoma(HCC) or cholangiocarcinoma cell lines.RESULTS:Immunostaining revealed constant expression of CD133 in non-neoplastic and neoplastic biliary epithelium,and these cells had the immunophenotype CD133+/CK19+/HepPar-1-.A small number of CD133+/CK19-/HepPar-1+ cells were also identified in HCC and combined hepatocellular and cholangiocarcinoma.In addition,small ductal structures,resembling the canal of Hering,partly surrounded by hepatocytes were positive for CD133.CD133 expression was observed in three HCC(HuH7,PLC5 and HepG2) and two cholangiocarcinoma cell lines(HuCCT1 and CCKS1).Fluorescence-activated cell sorting(FACS) revealed that CD133+ and CD133-cells derived from HuH7 and HuCCT1 cells similarly produced CD133+ and CD133-cells during subculture.To examine the relationship between CD133+ cells and the side population(SP) phenotype,FACS was performed using Hoechst 33342 and a monoclonal antibody against CD133.The ratios of CD133+/CD133-cells were almost identical in the SP and non-SP in HuH7.In addition,four different cellular populations(SP/CD133+,SP/CD133-,non-SP/CD133+,and non-SP/CD133-) could similarly produce CD133+ and CD133-cells during subculture.CONCLUSION:This study revealed that CD133 could be a biliary and progenitor cell marker in vivo.However,CD133 alone is not sufficient to detect tumor-initiating cells in cell lines. | Seiichi Yoshikawa Yoh Zen Takahiko Fujii Yasunori Sato Tetsuo Ohta Yutaka Aoyagi Yasuni Nakanuma | 2009 | World Journal of Gastroenterology2009，15，39： | 6 |
| 5 | Survival of geriatric patients after percutaneous endoscopic gastrostomy in Japan显示文摘AIM: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan. METHODS: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient’s characteristics at PEG using log-rank tests and Cox proportional hazard models. RESULTS: Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors. CONCLUSION: These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors. | Yutaka Suzuki Seryna Tamez Akihiko Murakami Akihiko Taira Akihiro Mizuhara Akira Horiuchi Chie Mihara Eiji Ako Hirohito Muramatsu Hitoshi Okano Hitoshi Suenaga Kazuaki Jomoto Junya Kobayashi Katsunari Takifuji Kazuhiro Akiyama Koh Tahara Koji Onishi Makoto Shimazaki Masami Matsumoto Masashi Ijima Masato Murakami Masato Nakahori Michiaki Kudo Michio Maruyama Mikako Takahashi Naohiro Washizawa Shigeru Onozawa Satoshi Goshi Satoyoshi Yamashita Shigeki Ono Shin Imazato Shinji Nishiwaki Shuichirou Kitahara Takao Endo Takao Iiri Takeshi Nagahama Takuto Hikichi Tatsuya Mikami Tetsuo Yamamoto Tetsushi Ogawa Tomoko Ogawa Tomoyuki Ohta Toshifumi Matsumoto Toshiroh Kura Tsutomu Kikuchi Tsuyoshi Iwase Tsuyotoshi Tsuji Yukio Nishiguchi Mitsuyoshi Urashima | 2010 | World Journal of Gastroenterology2010，16，40： | 4 |
| 6 | Clinical and radiological feature of lymphoepithelial cyst of the pancreas显示文摘A lymphoepithelial cyst(LEC)of the pancreas is a rare benign lesion.Because patients with LEC of the pancreas have a good prognosis,it is important that these lesions are accurately differentiated from other more aggressive pancreatic neoplasms for an appropriate treatment strategy.Previous studies have reported that a definitive diagnosis of LEC often cannot be obtained based solely on the findings of preoperative imaging(e.g.,Computed tomography or Magnetic resonance imaging).In this study,we reviewed four cases of pancreatic LECs to investigate the feature of LECs.We reviewed these cases with regard to symptoms,imaging findings,surgical procedures,and other clinical factors.We found that LEC was associated with unique characteristics on imaging findings.A preoperative diagnosisof LEC may be possible by comprehensively evaluating its clinical and imaging findings. | Hirofumi Terakawa Isamu Makino Hisatoshi Nakagawara Tomoharu Miyashita Hidehiro Tajima Hirohisa Kitagawa Takashi Fujimura Dai Inoue Kazuto Kozaka Toshifumi Gabata Tetsuo Ohta | 2014 | World Journal of Gastroenterology2014，20，45： | 4 |
| 7 | A case report of anaplastic carcinoma of the pancreas with remarkable intraductal tumor growth into the main pancreatic duct显示文摘We herein report a case of anaplastic carcinoma of the pancreas with remarkable intraductal tumor growth into the main pancreatic duct.A 76-year-old male was referred to our hospital for treatment of a pancreatic tumor.Preoperative examinations revealed a poorly defined tumor in the main pancreatic duct in the body of the pancreas,accompanied with severe dilatation of the main pancreatic duct,which was diagnosed as an intraductal papillary-mucinous neoplasm.We performed distal pancreatectomy and splenectomy.The pathological examination revealed that the tumor consisted of a mixture of anaplastic carcinoma(giant cell type)and adenocarcinoma in the pancreas.There was a papillary projecting tumor composed of anaplastic carcinoma in the dilated main pancreatic duct.The patient is now receiving chemotherapy because liver metastasis was detected 12 mo after surgery.In this case,we could observe a remarkable intraductal tumor growth into the main pancreatic duct.We also discuss the pathogenesis and characteristics of this rare tumor with specific tumor growth. | Mitsuyoshi Okazaki Isamu Makino Hirohisa Kitagawa Shinichi Nakanuma Hironori Hayashi Hisatoshi Nakagawara Tomoharu Miyashita Hidehiro Tajima Hiroyuki Takamura Tetsuo Ohta | 2014 | World Journal of Gastroenterology2014，20，3： | 2 |
| 8 | Intraductal papillary neoplasm of the bile duct accompanying biliary mixed adenoneuroendocrine carcinoma显示文摘We present the first case of an intraductal papillary neoplasm of the bile duct(IPNB) accompanying a mixed adenoneuroendocrine carcinoma(MANEC).A 74-yearold woman presented with fever of unknown cause.Laboratory data revealed jaundice and liver injury.Contrast-enhanced computed tomography revealed a 20 mm polypoid tumor in the dilated distal bile duct,which exhibited early enhancement and papillary growth.Upper gastrointestinal endoscopy revealed mucus production from the papilla of Vater,characterized by its protruding and dilated orifice.Endoscopic ultrasonography visualized the polypoid tumor in the distal bile duct,but no invasive region was suggested by diagnostic imaging.Therefore,the initial diagnosis was IPNB.After endoscopic nasobiliary drainage,a pylorus-preserving pancreaticoduodenectomy was performed.Pathological examination of the resected bile duct revealed papillary proliferation of biliary-type cells with nuclear atypia,indicating pancreaticobiliary-type IPNB.In addition,solid portions comprised of tumor cells with characteristic salt-and-pepper nuclei were evident.Immunohistochemistry revealed expression of the neuroendocrine marker synaptophysin in this solid component,diagnosing it as a neuroendocrine tumor(NET).Furthermore,the MIB-1 proliferation index of NET was higher than that of IPNB,and microinvasion of the NET component was found,indicating neuroendocrine carcinoma(NET G3).This unique case of MANEC,comprising IPNB and NET,provides insight into the pathogenesis of biliary NET. | Ichiro Onishi Hirohisa Kitagawa Kenichi Harada Syogo Maruzen Seisyo Sakai Isamu Makino Hironori Hayashi Hisatoshi Nakagawara Hidehiro Tajima Hiroyuki Takamura Takashi Tani Masato Kayahara Hiroko Ikeda Tetsuo Ohta Yasuni Nakanuma | 2013 | World Journal of Gastroenterology2013，19，20： | 2 |
