| 1 | Changes in growth factor and cytokine expression in biliary obstructed rat liver and their relationship with delayed liver regeneration after partial hepatectomy显示文摘瞄准:在部分肝切除术以后在肝新生上学习妨碍的黄疸的效果。方法: Hepatocyte 生长因素( HGF ),它的受体, 遇见c ,脉管的内皮生长因素( VEGF )和转变生长在肝织物和孤立的肝细胞的 factor-beta1 ( TGF-beta1 ) mRNA 表示被量的反向抄写的聚合酶链反应( RT-PCR )用 LightCycler 在胆汁的阻塞( BO )以后调查。为 desmin 和 alpha 光滑的肌肉肌动朊(alpha-SMA ) 染色的 Immunohistochemical 也被学习。标记的原子抗原(PCNA ) 索引的再生肝重量和增殖的房间,和生长因素表示然后与伴随物在 70% 肝切除术以后被评估在 BO 老鼠或假冒操作老鼠的内部胆汁的排水。结果:肝的 TGF-beta1 mRNA 层次显著地在 BO 以后增加了 14 天,并且进一步与胆汁郁积的持续时间增加了。同时, HGF 和 VEGF 趋于增加,但是不是重要的。在房间孤立, TGF-beta1 mRNA 主要在肝的星形的房间(HSC ) 被发现部分。Immunohistochemical 研究揭示了 HSC (desmin 积极的房间) 的一个增加的数字并且在 BO 以后在门区域激活 HSC (alpha-SMA-positive 房间) 。在一个肝切除术模型,肝新生在 BO 老鼠被推迟,作为与假冒操作老鼠相比。在肝切除术,和更早的 HGF mRNA 山峰沉醉于 BO 老鼠以后, TGF-beta1 mRNA 是显著地起来调整的直到 48 h。结论:BO 导致 HSC 增长和激活,导致 TGF-beta1 mRNA 的起来规定和在肝的 HGF mRNA 的抑制。这些改变的表示模式可以强烈与妨碍的黄疸在肝切除术以后涉及推迟的肝新生。 | Hironobu Makino Hiroaki Shimizu Hiroshi Ito Fumio Kimura Satoshi Ambiru Akira Togawa Masayuki Ohtsuka Hiroyuki Yoshidome Atsushi Kato Hideyuki Yoshitomi Shigeaki Sawada Masaru Miyazaki | 2006 | World Journal of Gastroenterology2006，12，13： | 32 |
| 2 | Short term results of endoscopic submucosal dissection in superficial esophageal squamous cell neoplasms显示文摘AIM: To evaluate the efficacy of endoscopic submucosal dissection for superficial esophageal squamous cell neoplasms. METHODS: Between July 2007 and March 2009, 27 consecutive superficial esophageal squamous cell neoplasms in 25 enrolled patients were treated by endoscopic submucosal dissection. The therapeutic efficacy, complications, and follow-up results were assessed. RESULTS: The mean size of the lesions was 21 ± 13 mm (range 2-55 mm); the mean size of the resection specimens was 32 ± 12 mm (range 10-70 mm). The enblock resection rate was 100% (27/27), and en block resection with tumor-free lateral/basal margins was 88.9% (24/27). Perforation occurred in 1 patient who was managed by conservative medical treatments. None of the patients developed local recurrence or distant metastasis in the follow-up period. CONCLUSION: Endoscopic submucosal dissection is applicable to superficial esophageal squamous cell neoplasms with promising results. | Kouichi Nonaka Shin Arai Keiko Ishikawa Masamitsu Nakao Yousuke Nakai Osamu Togawa Koji Nagata Michio Shimizu Yutaka Sasaki Hiroto Kita | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，2： | 19 |
| 3 | Multicenter study of endoscopic preoperative biliary drainage for malignant distal biliary obstruction显示文摘AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction.METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent(PS) or nasobiliary catheter(NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedurerelated adverse events, stent/catheter dysfunction(occlusion or migration of PS/NBC, developmentof cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution(bilirubin level < 3.0 mg/d L) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis.RESULTS: In total, 419 patients were included in the study(PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients(46%), bile duct cancer in 172(41%), gallbladder cancer in three(1%), and ampullary cancer in 50(12%). The median serum total bilirubin was 7.8 mg/d L and 324 patients(77%) had ≥ 3.0 mg/d L. During the median time to surgery of 29 d [interquartile range(IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio(SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method(PS or NBC).CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored. | Naoki Sasahira Tsuyoshi Hamada Osamu Togawa Ryuichi Yamamoto Tomohisa Iwai Kiichi Tamada Yoshiaki Kawaguchi Kenji Shimura Takero Koike Yu Yoshida Kazuya Sugimori Shomei Ryozawa Toshiharu Kakimoto Ko Nishikawa Katsuya Kitamura Tsunao Imamura Masafumi Mizuide Nobuo Toda Iruru Maetani Yuji Sakai Takao Itoi Masatsugu Nagahama Yousuke Nakai Hiroyuki Isayama | 2016 | World Journal of Gastroenterology2016，22，14： | 18 |
| 4 | Vascular endothelial growth factor and angiopoietins regulate sinusoidal regeneration and remodeling after partial hepatectomy in rats显示文摘AIM: To study the regulatory mechanisms of sinusoidal regeneration after partial hepatectomy.METHODS: We investigated the expression of angiopoietin (Ang)-1, Ang-2, Tie-2, and vascular endothelial growth factor (VEGF) in regenerating liver tissue by quantitative reverse-transcription polymerase chain reaction (RT-PCR) using a LightCycler (Roche Diagnostics) and also immunohistochemical staining after 70% hepatectomy in rats. In the next step, we isolated liver cells (hepatocytes,sinusoidal endothelial cell (SEC), Kupffer cell, and hepatic stellate cells (HSC)) from regenerating liver tissue by in situ collagenase perfusion and counterflow elutriation,to determine potential cellular sources of these angiogenic factors after hepatectomy. Proliferation and apoptosis of SECs were also evaluated by proliferating cell nuclear antigen (PCNA) staining and the terminal deoxynucleotidyl transferase d-uridine triphosphate nick end labeling (TUNEL) assay, respectively.RESULTS: VEGF mRNA expression increased with a peak at 72 h after hepatectomy, decreasing thereafter.The expression of Ang-1 mRNA was present at detectable levels before hepatectomy and increased slowly with a peak at 96 h. Meanwhile, Ang-2 mRNA was hardly detected before hepatectomy, but was remarkably induced at 120 and 144 h. In isolated cells, VEGF mRNA expression was found mainly in the hepatocyte fraction.Meanwhile, mRNA for Ang-1 and Ang-2 was foundin the SEC and HSC fractions, but was more prominent in the latter. The PCNA labeling index of SECs increased slowly,reaching a peak at 72 h, whereas apoptotic SECs were detected between 120 h and 144 h.CONCLUSION: Ang-Tie system, together with VEGF,plays a critical role in regulating balance between SEC proliferation and apoptosis during sinusoidal regeneration after hepatectomy. However, the VEGF system plays a more important role in the early phase of sinusoidal regeneration than angiopoietin/Tie system. | Hiroaki Shimizu Noboru Mitsuhashi Masayuki Ohtsuka Hiroshi Ito Fumio Kimura Satoshi Ambiru Akira Togawa Hiroyuki Yoshidome Atsushi Kato Masaru Miyazaki | 2005 | World Journal of Gastroenterology2005，11，46： | 17 |
| 5 | Reduced hemoglobin and increased C-reactive protein are associated with upper gastrointestinal bleeding显示文摘AIM: To investigate the early upper gastrointestinal endoscopy(endoscopy) significantly reduces mortality resulting from upper gastrointestinal(GI) bleeding. METHODS: Upper GI bleeding was defined as 1a, 1b, 2a, and 2b according to the Forrest classification. The hemoglobin(Hb), and C-reactive protein(CRP) were examined at around the day of endoscopy and 3 mo prior to endoscopy. The rate of change was calculated as follows:(the result of blood examination on the day of endoscopy- the results of blood examination 3 mo prior to endoscopy)/(results of blood examination 3 mo prior to endoscopy). Receiver operating characteristic curves were created to determine threshold values. RESULTS: Seventy-nine men and 77 women were enrolled. There were 17 patients with upper GI bleeding: 12 with a gastric ulcer, 3 with a duodenal ulcer, 1 with an acute gastric mucosal lesion, and 1 with gastric cancer. The area under the curve(AUC), threshold, sensitivity, and specificity of Hb around the day of endoscopy were 0.902, 11.7 g/dL, 94.1%, and 77.1%, respectively, while those of CRP were 0.722, 0.5 mg/dL, 70.5%, and 73%, respectively. The AUC, threshold, sensitivity, and specificity of the rate of change of Hb were 0.851,-21.3%, 76.4%, and 82.6%, respectively, while those of CRP were 0.901, 100%, 100%, and 82.5%, respectively. CONCLUSION: Predictors for upper GI bleeding were Hb < 11.7 g/dL, reduction rate in the Hb > 21.3% and an increase in the CRP > 100%, 3 mo before endoscopy. | Minoru Tomizawa Fuminobu Shinozaki Rumiko Hasegawa Akira Togawa Yoshinori Shirai Noboru Ichiki Yasufumi Motoyoshi Takao Sugiyama Shigenori Yamamoto Makoto Sueishi | 2014 | World Journal of Gastroenterology2014，20，5： | 13 |
| 6 | 在哪个与狭窄的乐队成像放大了内视镜检查法的胃的联系 mucosa 的淋巴的组织淋巴瘤的一个盒子在诊断是有用的显示文摘 Recently, we reported a case of gastric mucosaassociated lymphoid tissue (MALT) lymphoma presenting with unique vascular features. In the report, we defined the tree-like appearance (TLA) on the images of abnormal blood vessels which resembled branches from the trunk of a tree in the shiny mucosa, in which the glandular structure was lost. The 67-year-old female was diagnosed with gastric MALT lymphoma. The patient received eradication therapy for H. pylori. Conventional endoscopy revealed multiple ill-delineated brownish depressions in the stomach and cobblestonelike mucosa was observed at the greater curvature to the posterior wall of the upper gastric body 7 mo after successful eradication. Unsuccessful treatment of gastric MALT lymphoma was suspected on conventional endoscopy. Conventional endoscopic observations found focal depressions and cobblestone-like appearance, and these lesions were subsequently observed using magnified endoscopy combined with narrow band imaging to identify abnormal vessels presenting with a TLA within the lesions. Ten biopsies were taken from the area where abnormal vessels were present within these lesions. Ten biopsies were also taken from the lesions without abnormal vessels as a control. A total of 20 biopsy samples were evaluated to determine whether the diagnosis of MALT lymphoma could be obtained histologically from each sample. A positive diagnosis was obtained in 8/10 TLA (+) sites and in 2/10 TLA(-) sites. Target biopsies of the site with abnormal blood vessels can potentially improve diagnostic accuracy of gastric MALT lymphoma. | Kouichi Nonaka Keiko Ishikawa Shin Arai Masamitsu Nakao Michio Shimizu Takaki Sakurai Koji Nagata Makoto Nishimura Osamu Togawa Yasutoshi Ochiai Yutaka Sasaki Hiroto Kita | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，4： | 8 |
| 7 | 有为决定早阶段的区分的胃的癌的扩展区域的 NBI 的在我的 DL 的实用性显示文摘 AIM: To investigate whether magnifying endoscopy with narrow band imaging (ME-NBI) is useful for evaluating the area of superficial, depressed- or flat-type differentiated adenocarcinoma of the stomach. METHODS: This procedure was performed in Saitama Medical University International Medical Center, Japanese Red Cross Kumamoto Hospital and Kitakyushu Municipal Medical Center. The subjects were 31 patients in whom biopsy findings, from superficial, depressed- or flat-type gastric lesion, suggested differentiated adenocarcinoma in the above 3 hospitals between January and December 2009. Biopsy was performed on the lesion and non-lesion sides of a boundary (imaginary boundary) visualized on ME-NBI. The results were pathologically investigated. We evaluated the accuracy of estimating a demarcation line (DL) on ME-NBI in comparison with biopsy findings as a gold standard. RESULTS: The DL that could be recognized at 2 points on the orifice and anal sides of each lesion during ME-NBI was consistent with the pathological findings in 22 patients with 0-Ⅱc lesions, 7 with 0-Ⅱb lesions, and 2 with 0-Ⅱb + Ⅱc lesions, showing an accuracy of 100%. CONCLUSION: The results suggest the usefulness of ME-NBI for evaluating the area of superficial, depressed- and flat-type differentiated adenocarcinoma of the stomach. | Kouichi Nonaka Masaaki Namoto Hideki Kitada Michio Shimizu Yasutoshi Ochiai Osamu Togawa Masamitsu Nakao Makoto Nishimura Keiko Ishikawa Shin Arai Hiroto Kita | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，8： | 6 |
