1Clinical significance of serum levels of vascular endothelial growth factor and its receptor in biliary disease and carcinoma显示文摘AIM: To investigate the clinical significance of serum vascular endothelial growth factor (VEGF) and soluble VEGF receptor-1 (VEGFR1/Flt-1) (sVEGFR1) levels in biliary diseases.METHODS: We analyzed the serum levels of these proteins in patients with acute cholangitis (group 1), biliary malignancies (group 2), and primary biliary cirrhosis or primary sclerosing cholangitis (group 3), and in healthy donors (group 4). The influence of inflammation was also analyzed. Serum VEGF levels were expressed as VEGF per platelet (VEGF/PLT, pg/106) in order to exclude the influence of platelet counts.RESULTS: sVEGFR1 levels were significantly higher in groups 1 and 2 than in the control group, but did not correlate with inflammatory markers. VEGF/PLT levels were generally higher in patients with active inflammation than in those with carcinoma. C-reactive protein strongly correlated with the levels of serum VEGF independently of platelet and leukocyte counts, even in cancer patients. In cancer patients, VEGF/PLT and sVEGFR1 levels might be indicators for evaluating the effect of medical treatment or the disease progression.CONCLUSION: Serum VEGF and VEGFR1 might be useful markers for gauging the clinical effect of various treatments on patients.Munechika Enjoji Makoto Nakamuta Koji Yamaguchi Satoshi Ohta Kazuhiro Kotoh Marie Fukushima Masami Kuniyoshi Tomomi Yamada Masao Tanaka Hajime Nawata 2005World Journal of Gastroenterology2005,11,8:9

3Age-dependent eradication of Helicobacter pylori in Japanese patients显示文摘AIM:To determine the general risk factors affecting the failure rate of first-line eradication therapy in Japanese patients with Helicobacter pylori(H.pylori)infection.METHODS:The present study enrolled 253 patients who had an H.pylori infection,underwent gastroendoscopy,and were treated with H.pylori eradication therapy.Eradication therapy consisted of 30 mg lansoprazole plus 750 mg amoxicillin and 400 mg clarithromycin twice daily for 7 d.All of the patients underwent a 13 C urea breath test at least 1 mo after the completion of eradication therapy.The current study investigated the independent factors associated with successful H.pylori eradication using a multiple logistic regression analysis.RESULTS:The overall success rate in the patients was 85.8%.Among the general factors examined in the multivariate analyses,only having an age less than 50 years was found to be significantly associated with a poor response to H.pylori eradication.Moreover,side effects were the only clinical factors in the patients who were under 50 years of age that significantly influenced the poor response to H.pylori eradication.CONCLUSION:H.pylori-positive elderly patients should undergo eradication therapy.In addition,it is necessary to improve H.pylori eradication therapy in younger patients.Satoshi Mamori Akihiro Higashida Fumiaki Kawara Katsuhiro Ohnishi Akihiko Takeda Eri Senda Cho Ashida Hajime Yamada 2010World Journal of Gastroenterology2010,16,33:7
4Lymphomatoidgastropathy mimicking extranodal NK/T cell lymphoma,nasal type:A case report显示文摘Extranodal natural killer(NK)/T-cell lymphoma,nasal type,exhibits aggressive tumor behavior and carries a poor prognosis.Recently,lymphomatoid gastropathy with NK/T cell infiltration into gastric mucosa has been recognized as a pseudo-malignant disease which regresses without treatment.Because the conventional immunohistochemical criteria of lymphomatoid gastropathy is similar to that of extranodal NK/T-cell lymphoma nasal type,it is difficult to distinguish between the two conditions by histopathological evaluation only.Here,we report a rare case of lymphomatoid gastropathy in a 57-year-old female.Gastroendoscopy on routine check-up revealed elevated reddish lesions < 1 cm in diameter in the gastric fornix and body.Although repeat endoscopies at 1 and 6 mo later revealed no gastric lesions at any locations without any treatments,at 12 mo later gastric lymphomatoid lesions recurred at gastric fornix and body.Histological examination of endoscopic biopsy specimens at 12 mo showed atypical NK cell infiltration with CD3+,CD4-,CD5-,CD7+,CD8-,CD20-,CD30-,CD56+,CD79a-and T-cell-restricted intracellular antigen-1+ into gastric mucosa.After treatment for Helicobacter pylori(H.pylori) eradication,the lesions disappeared in all locations of the gastric fornix and body over the subsequent 12 mo.Here,we report a case of H.pylori-positive lymphomatoid gastropathy with massive NK-cell proliferation,and also review the literature concerning newly identified lymphomatoid gastropathy based on comparison of extra nodal NK/T-cell lymphoma nasal type.In any case,these lesions are evaluated with biopsy specimens,the possibility of this benign entity should be considered,and excessive treatment should be carefully avoided.Close follow-up for this case of lymphomatoid gastropathy is necessary to exclude any underlying malignancy.Tomohiro Terai Mitsushige Sugimoto Hiroki Uozaki Tetsushi Kitagawa Mana Kinoshita Satoshi Baba Takanori Yamada Satoshi Osawa Ken Sugimoto 2012World Journal of Gastroenterology2012,18,17:5
5Feasibility and safety of laparoscopic and endoscopic cooperative surgery for gastric submucosal tumors, including esophagogastric junction tumors显示文摘Shu Hoteya Shusuke Haruta Hisashi Shinohara Akihiro Yamada Tsukasa Furuhata Satoshi Yamashita Daisuke Kikuchi Toshifumi Mitani Osamu Ogawa Akira Matsui Toshiro Iizuka Harushi Udagawa Mitsuru Kaise 2014Digestive Endoscopy2014,,4:4
6Acid suppressive therapy improved symptoms due to circumferential cervical inlet patch with proton pumps(H^+/K^+-ATPase)显示文摘Cervical inlet patch(CIP), also referred to as esophageal heterotopic gastric mucosa, is regarded as the residue of columnar epithelium of the embryonic esophagus. Narrow band imaging increases the detection rate of CIP. Herein, we present a 55-year-old man with symptomatic circumferential inlet patch. He exhibited globus and dysphagia, and esophagogastroduodenoscopy found cir-cumferential CIP, where im-munohistochemistry revealed the existence of pro-ton pumps(H^+, K^+ -ATPase). His throat symptoms were relieved by acid suppressive therapy with pump inhibitors. This case indicated that CIP should be considered as a differential diagnosis for the cause of globus symptoms in rare cases.Takanori Yamada Atsushi Tsuji Shunya Onoue Masanao Kaneko Fumihiko Tanioka Satoshi Osawa Yasuhiko Saida 2017World Journal of Clinical Cases2017,5,11:3
7Intestinal anisakiasis can cause intussusception in adults:An extremely rare condition显示文摘We report an extremely rare case of adult intussusception caused by anisakiasis. A 41-year-old man was admitted into our hospital for right lower abdominal colicky pain. Ultrasonography and computed tomography revealed the presence of intussusception. As pneumodynamic resolution by colonoscopy failed, surgery was performed. The anisakis body was found in the submucosal layer of the resection specimen. The patient was discharged 9 d after the operation. Anisakiasis may cause intussusception in any country where sushi or sashimi now exists as a popular food. If suspicious, detailed clinical interview as to food intake prior to symptom development is crucial.Tomofumi Miura Akira Iwaya Takao Shimizu Junpei Tsuchiya Junichiro Nakamura Satoshi Yamada Tsutomu Miura Masahiko Yanagi Hiroyuki Usuda Iwao Emura Toru Takahashi 2010World Journal of Gastroenterology2010,16,14:3
8Image-based autonomous navigation of Hayabusa2 using artificial landmarks: The design and brief in-flight results of the first landing on asteroid Ryugu显示文摘Hayabusa2 is an asteroid sample return mission carried out by the Japan Aerospace Exploration Agency.The spacecraft was launched in 2014 and arrived at the target asteroid Ryugu on June 27,2018.During the 1.5-year proximity phase,several critical operations(including two landing/sampling operations)were successfully performed.They were based on autonomous image-based descent and landing techniques.This paper describes an imagebased autonomous navigation scheme of the Hayabusa2 mission using artificial landmarks named target markers(TMs).Its basic algorithm,and the in-flight results of the first touchdown and its rehearsal,are shown.Naoko Ogawa Fuyuto Terui Yuya Mimasu Kent Yoshikawa Go Ono Seiji Yasuda Kota Matsushima Tetsuya Masuda Hiroki Hihara Junpei Sano Takashi Matsuhisa Satoshi Danno Manabu Yamada Yasuhiro Yokota Yuto Takei Takanao Saiki Yuichi Tsuda 2020Astrodynamics2020,4,2:2
9TTF-1 is useful for primary site determination in duodenal metastasis显示文摘We report here on a case of duodenal metastasis from primary lung adenocarcinoma. A 69-year old man was diagnosed with primary lung adenocarcinoma. Four courses of combined chemotherapy with carboplatin and paclitaxel associated with irradiation of 60 Gy shrunk the lung tumor. However, soon after,the para-aortic lymph node became swollen. Esophagogastroduodenoscopy revealed three duodenal tumors. Differential diagnosis between malignant lymphoma and metastatic duodenal cancer was endoscopically difficult. The histology of biopsied specimens was poorly differentiated adenocarcinoma. Immunohistochemical analysis revealed a positive reaction for thyroid transcription factor-1 (TTF-1). Thus, we concluded that these were metastatic duodenal tumors from lung adenocarcinoma. Two courses of gemcitabine led to a complete remission in this duodenal metastasisand para-aortic lymph node swelling with only scarring remaining in computed tomography. He is now on the continuous generalized chemotherapy. In conclusion, duodenal metastasis from primary lung adenocarcinoma is rare and hard to diagnose. In such an instance, TTF-1 immunostaining is crucial to obtain the correct diagnosis.Tomofumi Miura Yuichi Shimaoka Junichiro Nakamura Satoshi Yamada Tsutomu Miura Masahiko Yanagi Kazuhiro Sato Hiroyuki Usuda Iwao Emura Toru Takahashi 2010World Journal of Gastrointestinal Oncology2010,2,9:2

15A case of small bowel adenocarcinoma in a patient with Crohn’s disease detected by PET/CT and double-balloon enteroscopy显示文摘Small bowel adenocarcinoma (SBA) in patients with Crohn’s disease (CD) is quite rare, difficult to diagnose without surgery, and has a poor prognosis. Here, we report a 48-year-old man with SBA and a 21-year history of CD who was diagnosed by a combination of positron emission tomography/computed tomography (PET/CT) and double-balloon enteroscopy (DBE). Since the age of 27 years, the patient had been treated for ileal CD and was referred to our hospital with persistent melena. Multiple hepatic tumors were found by CT. PET/CT detected an accumulation spot in the small bowel. DBE revealed an ulcerative tumor in the ileum about 100 cm from the ileocecal valve. An endoscopic forceps biopsy specimen showed poorly differentiated adenocarcinoma. There were some longitudinal ulcer scars near the tumor, and the chronic inflammation inthe small bowel appeared to be associated with the cancer development. Previous reports suggest the risk of SBA in patients with CD is higher than in the overall population. Since early diagnosis is extremely difficult in these cases, novel techniques, such as PET/CT and DBE, may be expected to help in making a preoperative diagnosis of the development of SBA in CD.Chise Kodaira Satoshi Osawa Chihiro Mochizuki Yoshihiko Sato Masafumi Nishino Takanori Yamada Yasuhiro Takayanagi Kosuke Takagaki Ken Sugimoto Shigeru Kanaoka Takahisa Furuta Mutsuhiro Ikuma 2009World Journal of Gastroenterology2009,15,14:2
16Sessile serrated adenoma detection rate is correlated with adenoma detection rate显示文摘AIM To investigated the association between adenoma detection rate(ADR) and sessile serrated ADR(SSADR) and significant predictors for sessile serrated adenomas(SSA) detection.METHODS This study is a retrospective, single-center analysis. Total colonoscopies performed by the gastroenterologists at the University of Tokyo Hospital between January and December 2014 were retrospectively identified. Polyps were classified as low-grade or high-grade adenoma, cancer, SSA, or SSA with cytological dysplasia, and the prevalence of each type of polyp was investigated. Predictors of adenoma and SSA detection were examined using logistic generalized estimating equation models. The association between ADR and SSADR for each gastroenterologist was investigated by calculating a correlation coefficient weighted by the number of each gastroenterologist's examination.RESULTS A total of 3691 colonoscopies performed by 35 gastroenterologists were assessed. Overall, 978 (26.5%) low-and 84 (2.2%) high-grade adenomas, 81 (2.2%) cancers, 66 (1.8%) SSAs, and 2 (0.1%) SSAs with cytological dysplasia were detected. Overall ADR was 29.5%(men 33.2%, women 23.8%) and overall SSADR was 1.8%(men 1.7%, women 2.1%). In addition, 672 low-grade adenomas (68.8% of all the detected lowgrade adenomas), 58 (69.9%) high-grade adenomas, 29 (34.5%) cancers, 52 (78.8%) SSAs, and 2 (100%) SSAs with cytological dysplasia were found in the proximal colon. Adenoma detection was the only significant predictor of SSA detection (adjusted OR: 2.53, 95%CI: 1.53-4.20; P < 0.001). The correlation coefficient between ADR and SSADR weighted by the number of each gastroenterologist's examinations was 0.606(P < 0.001).CONCLUSION Our results demonstrated that ADR is correlated to SSADR. In addition, patients with adenomas had a higher prevalence of SSAs than those without adenomas.Daisuke Ohki Yosuke Tsuji Tomohiro Shinozaki Yoshiki Sakaguchi Chihiro Minatsuki Hiroto Kinoshita Keiko Niimi Satoshi Ono Yoku Hayakawa Shuntaro Yoshida Atsuo Yamada Shinya Kodashima Nobutake Yamamichi Yoshihiro Hirata Tetsuo Ushiku Mitsuhiro Fujishiro Masashi Fukayama Kazuhiko Koike 2018World Journal of Gastrointestinal Oncology2018,10,3:2
