| 1 | Expression of Interleukin-26 is upregulated in inflammatory bowel disease显示文摘AIM To investigate interleukin(IL)-26 expression in the inflamed mucosa of patients with inflammatory bowel disease(IBD) and the function of IL-26. METHODS Human colonic subepithelial myofibroblasts(SEMFs) were isolated from colon tissue surgically resected. The expression of IL-26 protein and its receptor complex was analyzed by immunohistochemistry. The gene expression induced by IL-26 was evaluated by realtime polymerase chain reaction. Intracellular signaling pathways were evaluated by immunoblotting and specific small interfering(si) RNA transfection. RESULTS The m RNA and protein expression of IL-26 were significantly enhanced in the inflamed mucosa of patients with IBD. IL-26 receptor complex was expressed in colonic SEMFs in vivo and in vitro. IL-26 stimulated the m RNA expression of IL-6 and IL-8 in colonic SEMFs. The inhibitors of mitogen-activated protein kinases and phosphoinositide 3-kinase, and si RNAs for signal transducers and activator of transcription 1/3, nuclear factor-kappa B and activator protein-1 significantly reduced the m RNA expression of IL-6 and IL-8 induced by IL-26.CONCLUSION These results suggest that IL-26 plays a role in the pathophysiology of IBD through induction of inflammatory mediators. | Makoto Fujii Atsushi Nishida Hirotsugu Imaeda Masashi Ohno Kyohei Nishino Shigeki Sakai Osamu Inatomi Shigeki Bamba Masahiro Kawahara Tomoharu Shimizu Akira Andoh | 2017 | World Journal of Gastroenterology2017，23，30： | 8 |
| 2 | Cap polyposis refractory to Helicobacter pylori eradication treated with endoscopic submucosal dissection显示文摘Cap polyposis is a rare intestinal disorder. Characteristic endoscopic findings are multiple inflammatory polypoid lesions covered by caps of fibrous purulent exudate. Although a specific treatment has not been established, some studies have suggested that eradication therapy for Helicobacter pylori(H. pylori) is effective. We report a case of a 20-year-old man with cap polyposis presenting with hematochezia. Colonoscopy showed the erythematous polyps with white caps from the sigmoid colon to rectum. Histopathological findings revealed elongated, tortuous, branched crypts lined by hyperplastic epithelium with a mild degree of fibromusculosis in the lamina propria. Although H. pylori eradication was instituted, there was no improvement over six months. We then performed en bloc excision of the polyps by endoscopic submucosal dissection(ESD), which resulted in complete resolution of symptoms. ESD may be a treatment option for cap polyposis refractory to conservative treatments. We review the literature concerning treatment for cap polyposis and clinical outcomes. | Masaki Murata Mitsushige Sugimoto Hiromitsu Ban Taketo Otsuka Toshiro Nakata Masahide Fukuda Osamu Inatomi Shigeki Bamba Ryoji Kushima Akira Andoh | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，10： | 5 |
| 3 | Usefulness of the clip-flap method of endoscopic submucosal dissection: A randomized controlled trial显示文摘AIM To prospectively investigate the efficacy and safety of clipflap assisted endoscopic submucosal dissection(ESD) for gastric tumors.METHODS From May 2015 to October 2016, we enrolled 104 patients with gastric cancer or adenoma scheduled for ESD at Shiga University of Medical Science Hospital. We randomized patients into two subgroups using the minimization method based on location of the tumor(upper, middle or lower third of the stomach), tumor size(< 20 mm or > 20 mm) and ulcer status: ESD using an endoclip(the clip-flap group) and ESD without an endoclip(the conventional group). Therapeutic efficacy(procedure time) and safety(complication: Gastrointestinal bleeding and perforation) were assessed. RESULTS En bloc resection was performed in all patients. Four patients had delayed bleeding(3.8%) and two had perforation(1.9%). No significant differences in en bloc resection rate(conventional group: 100%, clip flap group: 100%), curative endoscopic resection rate(conventional group: 90.9%, clip flap group: 89.8%, P = 0.85), procedure time(conventional group: 70.8 ± 46.2 min, clip flap group: 74.7 ± 53.3 min, P = 0.69), area of resected specimen(conventional group: 884.6 ± 792.1 mm^2, clip flap group: 1006.4 ± 1004.8 mm^2, P = 0.49), delayed bleeding rate(conventional group: 5.5%, clip flap group: 2.0%, P = 0.49), or perforation rate(conventional group: 1.8%, clip flap group: 2.0%, P = 0.93) were found between the two groups. Lessexperienced endoscopists did not show any differences in procedure time between the two groups.CONCLUSION For patients with early-stage gastric tumors, the clipflap method has no advantage in efficacy or safety compared with the conventional method. | Hiromitsu Ban Mitsushige Sugimoto Taketo Otsuka Masaki Murata Toshiro Nakata Hiroshi Hasegawa Osamu Inatomi Shigeki Bamba Akira Andoh | 2018 | World Journal of Gastroenterology2018，24，35： | 4 |
| 4 | Efficacy of additional treatment with azathioprine in a patient with prednisolone-dependent gastric sarcoidosis显示文摘Gastric sarcoidosis with noncaseating granuloma is rare. Although corticosteroid produces a dramatic clinical response, it is unknown whether azathioprine show efficacy in prednisolone-dependent cases. Here, we report a case of gastric sarcoidosis in a 25-year-old man with severe epigastlargia. Gastroendoscopy revealed multiple map-like ulcerations. Histological examination showed multiple noncaseating granulomatous lesions in gastric mucosa, which were incompatible with diagnoses of Crohn's disease or tuberculosis. He was started on prednisolone at 30 mg/d, and his symptoms improved within 7-d. The prednisolone was gradually tapered by 5 mg every 2-wk, but oral azathioprine at 50 mg was added after symptoms recurred at tapered dose of 10 mg. Endoscopy 4-wk later showed healing ulcers, and, lymphocytic infiltration was absent. The efficacy of additional azathioprine in gastric sarcoidosis is not well defined. Here, we report a case of prednisolone-dependent gastric sarcoidosis that improved after additional azathioprine, and also review the literature concerning the treatment, especially for prednisolone-dependent cases. | Masaki Murata Mitsushige Sugimoto Yoshihiro Yokota Hiromitsu Ban Osamu Inatomi Shigeki Bamba Ryoji Kushima Akira Andoh | 2016 | World Journal of Gastroenterology2016，22，47： | 3 |

| 6 | Application of novel magnified single balloon enteroscopy for a patient with Cronkhite-Canada syndrome显示文摘We present a case of Cronkhite-Canada syndrome(CCS) in which the entire intestine was observed using a prototype of magnifying single-balloon enteroscope(SIF Y-0007, Olympus). CCS is a rare, non-familial gastrointestinal polyposis with ectodermal abnormalities. To our knowledge, this is the first report showing magnified intestinal lesions of CCS. A 73-year-old female visited our hospital with complaints of diarrhea and dysgeusia. The blood test showed mild anemia and hypoalbuminemia. The esophagogastroduodenoscopy and colonoscopy revealed diffuse and reddened sessile to semi-pedunculated polyps, resulting in the diagnosis of CCS. In addition to the findings of conventional balloon-assisted enteroscopy or capsule endoscopy, magnifying observation revealed tiny granular structures, non-uniformity of the villus, irregular caliber of the loop-like capillaries, scattered white spots in the villous tip, and patchy redness of the villus. Histologically, the scattered white spots and patchy redness of the villus reflect lymphangiectasia and bleeding to interstitium, respectively. | Masaki Murata Shigeki Bamba Kenichiro Takahashi Hirotsugu Imaeda Atsushi Nishida Osamu Inatomi Tomoyuki Tsujikawa Ryoji Kushima Mitsushige Sugimoto Akira Andoh | 2017 | World Journal of Gastroenterology2017，23，22： | 2 |

| 8 | Severity of gastric mucosal atrophy affects the healing speed of post-endoscopic submucosal dissection ulcers显示文摘AIM To investigate factors associated with the healing of endoscopic submucosal dissection(ESD)-induced ulcers.METHODS We enrolled 132 patients with gastric tumors scheduled for ESD. Following ESD, patients were treated with daily lansoprazole 30 mg or vonoprazan 20 mg. Ulcer size was endoscopically measured on the day after ESD and at 4 and 8 wk. The gastric mucosa was endoscopically graded according to the Kyoto gastritis scoring system. We assessed the number of patients with and without a 90% reduction in ulcer area at 4 wk post-ESD and scar formation at 8 wk, and looked for risk factors for slower healing.RESULTS The mean size of gastric tumors and post-ESD ulcers was 17.4 ± 12.1 mm and 32.9 ± 13.0 mm. The meanreduction rates in ulcer area were 90.4% ± 0.8% at 4 wk and 99.8% ± 0.1% at 8 wk. The reduction rate was associated with the Kyoto grade of gastric atrophy at 4 wk(A0: 97.9% ± 0.6%, A1: 93.4% ± 4.1%, and A2: 89.7% ± 1.0%, respectively). In multivariate analysis, the factor predicting 90% reduction at 4 wk was gastric atrophy(Odds ratio: 5.678, 95%CI: 1.190-27.085, P = 0.029).CONCLUSION The healing speed of post-ESD ulcers was associated with the degree of gastric mucosal atrophy, and Helicobacter pylori eradication therapy is required to perform at younger age. | Taketo Otsuka Mitsushige Sugimoto Hiromitsu Ban Toshiro Nakata Masaki Murata Atsushi Nishida Osamu Inatomi Shigeki Bamba Akira Andoh | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，5： | 2 |
