| 1 | Treatment strategy for gastric non-invasive intraepithelial neoplasia diagnosed by endoscopic biopsy显示文摘Treatment strategies,whether as follow-up or'total incisional biopsy'for gastric noninvasive intraepithelial neoplasia diagnosed by examination of an endoscopic forceps biopsy specimen,are controversial due to problems associated with the diagnostic accuracy of endoscopic forceps biopsy and questions about the safety and efficacy of endoscopic treatment.Based on the histological findings of the biopsy specimen,it is difficult to differentiate between reactive or regenerative changes,inflammation and neoplastic changes,intraepithelial and invasive tumors.Therefore,gastric neoplasia diagnosed as noninvasive intraepithelial often develop into invasive carcinoma during follow-up.Recent advances in endoscopic modalities and treatment devices,such as image-enhanced endoscopy and highfrequency generators,may make endoscopic treatment,such as endoscopic submucosal dissection(ESD),a therapeutic option for gastric intraepithelial neoplasia,including low-grade neoplasms.Future studies are required to evaluate whether ESD is a valid strategy for gastric intraepithelial neoplasm with regard to safety and cost effectiveness. | Tsutomu Nishida Shusaku Tsutsui Motohiko Kato Takuya Inoue Shunsuke Yamamoto Yoshito Hayashi Tomofumi Akasaka Takuya Yamada Shinichiro Shinzaki Hideki Iijima Masahiko Tsujii Tetsuo Takehara | 2011 | World Journal of Gastrointestinal Pathophysiology2011，2，6： | 18 |
| 2 | Comparative study of esomeprazole and lansoprazole in triple therapy for eradication of Helicobacter pylori in Japan显示文摘AIM:To evaluate the efficacy and safety of esomeprazole-based triple therapy compared with lansoprazole therapy as first-line eradication therapy for patients with Helicobacter pylori(H.pylori)in usual post-marketing use in Japan,where the clarithromycin(CAM)resistance rate is 30%.METHODS:For this multicenter,randomized,openlabel,non-inferiority trial,we recruited patients(≥20years of age)with H.pylori infection from 20 hospitals in Japan.We randomly allocated patients to esomeprazole therapy(esomeprazole 20 mg,CAM 400 mg,amoxicillin(AC)750 mg for the first 7 d,with all drugs given twice daily)or lansoprazole therapy(lansoprazole30 mg,CAM 400 mg,AC 750 mg for the first 7 d,with all drugs given twice daily)using a minimization method with age,sex,and institution as adjustment factors.Our primary outcome was the eradication rate by intention-to-treat(ITT)and per-protocol(PP)analyses.H.pylori eradication was confirmed by a urea breath test from 4 to 8 wk after cessation of therapy.RESULTS:ITT analysis revealed the eradication rates of 69.4%(95%CI:61.2%-76.6%)for esomeprazole therapy and 73.9%(95%CI:65.9%-80.6%)for lansoprazole therapy(P=0.4982).PP analysis showed eradication rate of 76.9%(95%CI:68.6%-83.5%)for esomeprazole therapy and 79.8%(95%CI:71.9%-86.0%)for lansoprazole therapy(P=0.6423).There were no differences in adverse effects between the two therapies.CONCLUSION:Esomeprazole showed non-inferiority and safety in a 7 day-triple therapy for eradication of H.pylori compared with lansoprazole. | Tsutomu Nishida Masahiko Tsujii Hirohisa Tanimura Shusaku Tsutsui Shingo Tsuji Akira Takeda Atsuo Inoue Hiroyuki Fukui Toshiyuki Yoshio Osamu Kishida Hiroyuki Ogawa Masahide Oshita Ichizo Kobayashi Shinichiro Zushi Makoto Ichiba Naoto Uenoyama Yuichi Yasunaga Ryu Ishihara Mamoru Yura Masato Komori Satoshi Egawa Hideki Iijima Tetsuo Takehara | 2014 | World Journal of Gastroenterology2014，20，15： | 13 |
| 3 | Inflammatory pseudotumor of the liver and spleen diagnosed by percutaneous needle biopsy显示文摘An inflammatory pseudotumor (IPT) is a relatively rare lesion characterized by chronic inf iltration of inflammatory cells and areas of f ibrosis. IPTs are diff icult to diagnose because of the absence of specif ic symptoms or of characteristic hematological or radiological f indings. In this study, a case of a woman aged over 70 years was reported, who presented with a general malaise lasting more than two months. A computed tomography scan demonstrated a diffusely spread lesion of the liver with a portal vein occlusion and a splenic lesion surrounded by a soft density layer. Since the percutaneous liver biopsy showed f indings that suggested an IPT, although the radiological f indings did not exclude the possibility of a malignancy, we performed a percutaneous spleen biopsy to enable a more defi nitive diagnosis. The microscopic f indings from the spleen specimen lead us to a diagnosis of IPT involving the liver and spleen. Sub-sequent steroid pulse therapy was effective, and rapid resolution of the disease was observed. | Tsukasa Kawaguchi Kiyoshi Mochizuki Takashi Kizu Masanori Miyazaki Takayuki Yakushijin Shusaku Tsutsui Eiichi Morii Tetsuo Takehara | 2012 | World Journal of Gastroenterology2012，18，1： | 11 |

| 5 | Choroidal and cutaneous metastasis from gastric adenocarcinoma显示文摘Choroidal or cutaneous metastasis of gastric cancer is rare. Gastrointestinal cancer was found in only 4% in patients with uveal metastasis. Choroidal metastasis from gastric cancer was reported in two cases in earlier literature. The frequency of gastric cancer as a primary lesion was 6% in cutaneous metastasis of men, and cutaneous metastasis occurs in 0.8% of all gastric cancers. We report a patient with gastric adenocarcinoma who presented with visual disorder in his left eye and skin pain on his head as his initial symptoms. These symptoms were diagnosed to be caused by choroidal and cutaneous metastasis of gastric adenocarcinoma. Two cycles of chemotherapy consisted of oral S-1 and intravenous cisplatin (SPIRITS regimen); this was markedly effective to reduce the primary gastric lesion and almost all the metastatic lesions. | Shoichiro Kawai Tsutomu Nishida Yoshito Hayashi Hisao Ezaki Takuya Yamada Shinichiro Shinzaki Masanori Miyazaki Kei Nakai Takayuki Yakushijin Kenji Watabe Hideki Iijima Masahiko Tsujii Kohji Nishida Tetsuo Takehara | 2013 | World Journal of Gastroenterology2013，19，9： | 6 |
| 6 | Esophageal early basaloid squamous carcinoma with unusual narrowband imaging magnified endoscopy findings显示文摘Basaloid squamous carcinoma(BSC)is a rare variant of esophageal cancer.There are very few reports of'early'BSC.Here we report a case of early BSC with unusual findings by narrowband imaging magnified endoscopy(NBI-ME).A 70-year-old man with a middle thoracic esophageal tumor was referred to our hospital.White-light endoscopy revealed a reddish depressed lesion 5 mm in diameter having a subepithelial tumor-like prominence with a gentle rising slope.NBI-ME revealed irregular loop-shaped microvessels coexistent with thick irregularly branched non-looped vessels.Iodine staining revealed a pale brown lesion.We performed endoscopic submucosal dissection for diagnostic treatment.Histologic examination showed the proliferation of basal cell-like hyperchromatic tumor cells in the lamina propria and with slight invasion into the submucosa at a depth of 320μm.The tumor cells formed solid nests and microcystic structures,containing an Alcian blue-positive mucoid matrix.The surface was covered with squamous epithelium without cellular atypia.Thin vessels were observed in the intra-epithelial papilla and thick vessels were observed around the solid nests beneath the epithelium.Based on these findings together,we diagnosed the lesion as BSC.In this case,the NBI-ME findings differed from those of typical squamous cell carcinoma in that both non-invasive cancer-like irregular loop-shaped microvessels coexisted with massively invasive cancerlike thick non-looped vessels.We speculate that the looped and non-looped vessels observed by NBI-ME histologically corresponded to thin vessels in the intraepithelial papilla and thick vessels around the tumor nests,respectively.These NBI-ME findings might be a feature of early esophageal BSC. | Yugo Kai Motohiko Kato Yoshito Hayashi Tomofumi Akasaka Shinichiro Shinzaki Tsutomu Nishida Masahiko Tsujii Eiichi Morii Tetsuo Takehara | 2014 | World Journal of Gastroenterology2014，20，35： | 4 |
| 7 | Endoscopic submucosal dissection in early gastric cancer in elderly patients and comorbid conditions显示文摘The prognosis of early gastric cancer(EGC) is good if there is no concomitant lymph node metastasis. Therefore, the early detection of EGC is important to improve the prognosis of patients with gastric cancer. In Japan, 40% to 50% of all gastric cancers are EGC, and endoscopic submucosal dissection(ESD) is widely accepted as a local treatment for these lesions, particularly for large lesions that at one time were an indication for gastrectomy because of the difficulty of en-bloc resection. Consequently, this procedure can preserve the entire stomach and the patient's postoperative quality of life. ESD has become a general technique with improved procedures and devices, and has become the preferred treatment for EGC rather than gastrectomy. Therefore, ESD may demonstrate many advantages in patients who have several comorbidities, particularly elderly population, patients taking antithrombotic agents, or patients with chronic kidney disease, or liver cirrhosis. However, it is not yet clear whether patients with both EGC and comorbidities are feasible candidates for ESD and whether they would consequently be able to achieve a survival benefit after ESD. In this review, we discuss the clinical problems of ESD in patients with EGC and those comorbid conditions. | Tsutomu Nishida Motohiko Kato Toshiyuki Yoshio Tomofumi Akasaka Teppei Yoshioka Tomoki Michida Masashi Yamamoto Shiro Hayashi Yoshito Hayashi Masahiko Tsujii Tetsuo Takehara | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，5： | 4 |
| 8 | Endoscopic surveillance strategy after endoscopic resection for early gastric cancer显示文摘Early detection of early gastric cancer(EGC)is important to improve the prognosis of patients with gastric cancer.Recent advances in endoscopic modalities and treatment devices,such as image-enhanced endoscopy and high-frequency generators,may make endoscopic treatment,such as endoscopic submucosal dissection,a therapeutic option for gastric intraepithelial neoplasia.Consequently,short-term outcomes of endoscopic resection(ER)for EGC have improved.Therefore,surveillance with endoscopy after ER for EGC is becoming more important,but how to perform endoscopic surveillance after ER has not been established,even though the follow-up strategy for more advanced gastric cancer has been outlined.Therefore,a surveillance strategy for patients with EGC after ER is needed. | Tsutomu Nishida Masahiko Tsujii Motohiko Kato Yoshito Hayashi Tomofumi Akasaka Hideki Iijima Tetsuo Takehara | 2014 | World Journal of Gastrointestinal Pathophysiology2014，5，2： | 4 |
| 9 | OsIDD2, a zinc finger and INDETERMINATE DOMAIN protein, regulates secondary cell wall formation显示文摘Previously, we found 123 transcription factors(TFs) as candidate regulators of secondary cell wall(SCW)formation in rice by using phylogenetic and co-expression network analyses. Among them, we examined in this work the role of OsIDD_2, a zinc finger and indeterminate domain(IDD) family TF. Its overexpressors showed dwarfism, fragile leaves, and decreased lignin content, which are typical phenotypes of plants defective in SCW formation, whereas its knockout plants showed slightly increased lignin content.The RNA-seq and quantitative reverse transcription polymerase chain reaction analyses confirmed that some lignin biosynthetic genes were downregulated in the OsIDD_2-overexpressing plants, and revealed the same case for other genes involved in cellulose synthesis and sucrose metabolism. The transient expression assay using rice protoplasts revealed that OsIDD_2 negatively regulates the transcription of genes involved in lignin biosynthesis, cinnamyl alcohol dehydrogenase 2 and 3(CAD_2 and 3), and sucrose metabolism, sucrose synthase 5(SUS_5), whereas an Alpha Screen assay, which can detect the interaction between TFs and their target DNA sequences, directly confirmed the interaction between OsIDD_2 and the target sequences located in the promoter regions of CAD_2 and CAD_3. Based on these observations, we conclude that OsIDD_2 is negatively involved in SCW formation and other biological events by downregulating its target genes. | Peng Huang Hideki Yoshida Kenji Yano Shunsuke Kinoshita Kyosuke Kawai Eriko Koketsu Masako Hattori Sayaka Takehara Ji Huang Ko Hirano Reynante Lacsamana Ordonio Makoto Matsuoka Miyako Ueguchi-Tanaka | 2018 | Journal of Integrative Plant Biology2018，60，2： | 3 |
| 10 | Alpha-fetoprotein and des-gamma-carboxy-prothrombin at twenty-four weeks after interferon-based therapy predict hepatocellular carcinoma development显示文摘AIM: To investigate risk factors for development of hepatocellular carcinoma(HCC) in patients with hepatitis C virus-related liver cirrhosis(LC-C).METHODS: To evaluate the relationship between clinical factors including virological response and the development of HCC in patients with LC-C treated with interferon(IFN) and ribavirin, we conducted a multicenter, retrospective study in 14 hospitals in Japan. All patients had compensated LC-C with clinical or histological data available. HCC was diagnosed by the presence of typical hypervascular characteristics on computed tomography and/or magnetic resonance imaging.RESULTS: HCC was diagnosis in 50(21.6%) of 231 LC-C patients during a median observation period of 3.8 years after IFN and ribavirin therapy. Patients who developed HCC were older(P = 0.018) and had higher serum levels of pretreatment alpha-fetoprotein(AFP)(P = 0.038). Multivariate analysis revealed the following independent risk factors for HCC development: history of treatment for HCC [P < 0.001, odds ratio(OR) = 15.27, 95%CI: 4.98-59.51], AFP levels of ≥ 10 ng/m L(P = 0.009, OR = 3.89, 95%CI: 1.38-11.94), and des-γ-carboxy prothrombin(DCP) levels of ≥ 40 m AU/mL at 24 wk after the completion of IFN and ribavirin therapy(P < 0.001, OR = 24.43, 95%CI: 4.11-238.67).CONCLUSION: We suggested that the elevation of AFP and DCP levels at 24 wk after the completion of IFN and ribavirin therapy were strongly associated with the incidence of HCC irrespective of virological response among Japanese LC-C patients. | Satoshi Shakado Shotaro Sakisaka Kazuaki Chayama Takeshi Okanoue Joji Toyoda Namiki Izumi Akihiro Matsumoto Tetsuo Takehara Akio Ido Yoichi Hiasa Kentaro Yoshioka Hideyuki Nomura Yoshiyuki Ueno Masataka Seike Hiromitsu Kumada | 2015 | World Journal of Hepatology2015，7，27： | 3 |
| 11 | Percutaneous endoscopic gastrostomy under steadypressure automatically controlled endoscopy:First clinicalseries显示文摘AIM: To elucidate the safety of percutaneous endoscopic gastrostomy(PEG) under steady pressure automatically controlled endoscopy(SPACE) using carbon dioxide(CO_2).METHODS: Nine patients underwent PEG with a modified introducer method under conscious sedation. A T-tube was attached to the channel of an endoscope connected to an automatic surgical insufflator. The stomach was inflated under the SPACE system. The intragastric pressure was kept between 4-8 mmH g with a flow of CO_2 at 35 L/min. Median procedure time, intragastric pressure, median systolic blood pressure, partial pressure of CO_2, abdominal girth before and immediately after PEG, and free gas and small intestinal gas on abdominal X-ray before and after PEG were recorded. RESULTS: PEG was completed under stable pneumostomach in all patients, with a median procedural time of 22 min. Median intragastric pressure was 6.9 mmH g and median arterial CO_2 pressure before and after PEG was 42.1 and 45.5 Torr(NS). The median abdominal girth before and after PEG was 68.1 and 69.6 cm(NS). A mild free gas image after PEG was observed in two patients, and faint abdominal gas in the downstream bowel was documented in two patients.CONCLUSION: SPACE might enable standardized pneumostomach and modified introducer procedure of PEG. | Hiroyuki Imaeda Kiyokazu Nakajima Naoki Hosoe Masanori Nakahara Shinichiro Zushi Motohiko Kato Kazuhiro Kashiwagi Yasushi Matsumoto Kayoko Kimura Rieko Nakamura Norihito Wada Masahiko Tsujii Naohisa Yahagi Toshifumi Hibi Takanori Kanai Tetsuo Takehara Haruhiko Ogata | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，3： | 2 |

| 13 | Mechanisms of the autophagosome-lysosome fusion step and its relation to non-alcoholic fatty liver disease显示文摘Macroautophagy(hereafter autophagy)is a catabolic process by which autophagosomes arising from an isolation membrane fuse with lysosomes to degrade components in the cytoplasm.Autophagosomelysosome fusion step is one of the key steps during the process of macroautophagy.The step is extremely complicated and its detailed mechanisms remain unclear.It consists of two phases:first phase is autophagosome migration phase and second phase is fusion of autophagosomes and lysosomes phase.Recently,various molecules have been reported to be involved in each phase.In the first phase,microtubules and actin remodeling mechanism are involved.In the second phase,soluble N-ethylmaleimide-sensitive factor attachment protein receptor(SNARE)proteins,Rab family proteins,phosphoinositide 3-kinase(PI3K)complex and Rubicon are involved.In the present review,we introduce recent findings related to autophagosome-lysosome fusion step and discuss liver diseases possibly associated with autophagosome-lysosome fusion dysfunction. | Hayato Hikita Sadatsugu Sakane Tetsuo Takehara | 2018 | Liver Research2018，2，3： | 2 |

| 15 | Clinical problems with antithrombotic therapy for endoscopic submucosal dissection for gastric neoplasms显示文摘Endoscopic submucosal dissection(ESD) is minimally invasive and thus has become a widely accepted treatment for gastric neoplasms,particularly for patients with comorbidities.Antithrombotic agents are used to prevent thrombotic events in patients with comorbidities such as cardio-cerebrovascular diseases and atrial fibrillation.With appropriate cessation,antithrombotic therapy does not increase delayed bleeding in low thrombosis-risk patients.However,high thrombosisrisk patients are often treated with combination therapy with antithrombotic agents and occasionally require the continuation of antithrombotic agents or heparin bridge therapy(HBT) in the perioperative period.Dual antiplatelet therapy(DAPT),a representative combination therapy,is frequently used after placement of drug-eluting stents and has a high risk of delayed bleeding.In patients receiving DAPT,gastric ESD may be postponed until DAPT is no longer required.HBT is often required for patients treated with anticoagulants and has an extremely high bleeding risk.The continuous use of warfarin or direct oral anticoagulants may be possible alternatives.Here,we show that some antithrombotic therapies in high thrombosis-risk patients increase delayed bleeding after gastric ESD,whereas most antithrombotic therapies do not.The management of high thrombosis-risk patients is crucial for improved outcomes. | Toshiyuki Yoshio Tsutomu Nishida Yoshito Hayashi Hideki Iijima Masahiko Tsujii Junko Fujisaki Tetsuo Takehara | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，20： | 2 |
