| 1 | Crosstalk between angiogenesis, cytokeratin-18, and insulin resistance in the progression of non-alcoholic steatohepatitis显示文摘AIM: To elucidate the possible crosstalk between angiogenesis, cytokeratin-18 (CK-18), and insulin resistance (IR) especially in patients with non-alcoholic steatohepatitis (NASH).METHODS: Twenty-eight patients with NASH and 11 with simple fatty liver disease (FL) were enrolled in this study and underwent clinicopathological examination. The measures of angiogenesis, CK-18, and IR employed were CD34-immunopositive vessels, CK-18immunopositive cells, and homeostasis model assessment of IR (HOMA-IR), respectively. The correlations of these factors with NASH were elucidated.RESULTS: Significant development of hepatic neovascularization was observed only in NASH, whereas almost no neovascularization could be observed in FL and healthy liver. The degree of angiogenesis was almost parallel to liver fibrosis development, and both parameters were positively correlated. Similarly, CK-18expression and HOMA-R were signifi cantly increased in NASH as compared with FL and healthy liver. Furthermore, CK-18 and HOMA-IR were also positively correlated with the degree of neovascularization. CONCLUSION: These results indicate that the crosstalk between angiogenesis, CK-18, and IR may play an important role in the onset and progression of NASH. | Mitsuteru Kitade Hitoshi Yoshiji Ryuichi Noguchi Yasuhide Ikenaka Kosuke Kaji Yusaku Shirai Masaharu Yamazaki Masahito Uemura Junichi Yamao Masao Fujimoto Akira Mitoro Masahisa Toyohara Masayoshi Sawai Motoyuki Yoshida Chie Morioka Tatsuhiro Tsujimoto Hideto Kawaratani Hiroshi Fukui | 2009 | World Journal of Gastroenterology2009，15，41： | 9 |
| 2 | Endoscopic diagnosis for colorectal sessile serrated lesions显示文摘BACKGROUND Hyperplastic polyps are considered non-neoplastic, whereas sessile serrated lesions(SSLs) are precursors of cancer via the ‘‘serrated neoplastic pathway’’. The clinical features of SSLs are tumor size(> 5 mm), location in the proximal colon, coverage with abundant mucus called the ‘‘mucus cap’’, indistinct borders, and a cloud-like surface. The features in magnifying narrow-band imaging are varicose microvascular vessels and expanded crypt openings. However, accurate diagnosis is often difficult.AIM To develop a diagnostic score system for SSLs.METHODS We retrospectively reviewed consecutive patients who underwent endoscopic resection during colonoscopy at the Toyoshima endoscopy clinic. We collected data on serrated polyps diagnosed by endoscopic or pathological examination. The significant factors for the diagnosis of SSLs were assessed using logistic regression analysis. Each item that was significant in multivariate analysis was assigned 1 point, with the sum of these points defined as the endoscopic SSL diagnosis score. The optimal cut-off value of the endoscopic SSL diagnosis score was determined by receiver-operating characteristic curve analysis.RESULTS Among 1288 polyps that were endoscopically removed, we analyzed 232 diagnosed as serrated polyps by endoscopic or pathological examination. In the univariate analysis, the location(proximal colon), size(> 5 mm), mucus cap, indistinct borders, cloud-like surface, and varicose microvascular vessels were significantly associated with the diagnosis of SSLs. In the multivariate analysis, size(> 5 mm;P = 0.033), mucus cap(P = 0.005), and indistinct borders(P = 0.033) were independently associated with the diagnosis of SSLs. Size > 5 mm, mucus cap, and indistinct borders were assigned 1 point each and the sum of these points was defined as the endoscopic SSL diagnosis score. The receiver-operating characteristic curve analysis showed an optimal cut-off score of 3, which predicted pathological SSLs with 75% sensitivity, 80% specificity, and 78.4% accuracy. The pathological SSL rate for an endoscopic SSL diagnosis score of 3 was significantly higher than that for an endoscopic SSL diagnosis score of 0, 1, or 2(P < 0.001).CONCLUSION Size > 5 mm, mucus cap, and indistinct borders were significant endoscopic features for the diagnosis of SSLs. Serrated polyps with these three features should be removed during colonoscopy. | Toshihiro Nishizawa Shuntaro Yoshida Akira Toyoshima Tomoharu Yamada Yoshiki Sakaguchi Taiga Irako Hirotoshi Ebinuma Takanori Kanai Kazuhiko Koike Osamu Toyoshima | 2021 | World Journal of Gastroenterology2021，27，13： | 7 |
| 3 | Feasibility of initial endoscopic common bile duct stone removal in patients with acute cholangitis显示文摘AIM To investigate the feasibility of initial endoscopic common bile duct(CBD) stone removal in patients with acute cholangitis(AC).METHODS A single-center,retrospective study was conducted between April 2013 and December 2014 and was approved by the Medical Ethics Committee at our institution.Written informed consent was obtained from each patient prior to the procedure.The cohort comprised 31 AC patients with CBD stones who underwent endoscopic biliary drainage(EBD) for na?ve papilla within 48 h after AC onset.We retrospectively divided the participants into two groups: 19 patients with initial endoscopic CBD stone removal(initial group) and 12 patients with delayed endoscopic CBD stone removal(delayed group).We evaluated the feasibility of initial endoscopic CBD stone removal in patients with AC.RESULTS We observed no significant differences between the groups regarding patient characteristics.According to the assessments based on the Tokyo Guidelines,the AC severity of patients with initial endoscopic CBD stone removal was mild to moderate.The use of antithrombotic agents before EBD was less frequent in the initial group than in the delayed group(11% vs 58%,respectively; P = 0.004).All the patients underwent successful endoscopic CBD stone removaland adverse events did not differ significantly between the groups.The number of endoscopic retrograde cholangiopancreatography procedures was significantly lower in the initial group than in the delayed group [median(interquartile range) 1(1-1) vs 2(2-2),respectively; P < 0.001].The length of hospital stay was significantly shorter for the initial group than for the delayed group [10(9-15) vs 17(14-20),respectively; P = 0.010].CONCLUSION Initial endoscopic CBD stone removal in patients with AC may be feasible when AC severity and the use of antithrombotic agents are carefully considered. | Akira Yamamiya Katsuya Kitamura Yu Ishii Yuta Mitsui Tomohiro Nomoto Hitoshi Yoshida | 2017 | World Journal of Clinical Cases2017，5，7： | 5 |
| 4 | Endovascular treatment of post-laparoscopic pancreatectomy splenic arteriovenous fistula with splenic vein aneurysm显示文摘Splenic arteriovenous fistulas(SAVFs) with splenic vein aneurysms are extremely rare entities. There have been no prior reports of SAVFs developing after laparoscopic pancreatectomy. Here, we report the first case. A 40-year-old man underwent a laparoscopic, spleen-preserving, distal pancreatectomy for an endocrine neoplasm of the pancreatic tail. Three months after surgery, a computed tomography(CT) scan demonstrated an SAVF with a dilated splenic vein. The SAVF, together with the splenic vein aneurysm, was successfully treated using percutaneous transarterial coil embolization of the splenic artery, including the SAVF and drainage vein. After the endovascular treatment, the patient's recovery was uneventful. He was discharged on postoperative day 6 and continues to be well 3 mo after discharge. An abdominal CT scan performed at his 3-mo follow-up demonstrated complete thrombosis of the splenic vein aneurysm, which had decreased to a 40 mm diameter. This is the first reported case of SAVF following a laparoscopic pancreatectomy and demonstrates the usefulness of endovascular treatment for this type of complication. | Tatsuo Ueda Satoru Murata Akira Yamamoto Jin Tamai Yuko Kobayashi Chiaki Hiranuma Hiroshi Yoshida Shin-ichiro Kumita | 2015 | World Journal of Gastroenterology2015，21，25： | 5 |
| 5 | Combined treatment of vitamin K_2 and angiotensin-converting enzyme inhibitor ameliorates hepatic dysplastic nodule in a patient with liver cirrhosis显示文摘Although it is well known that the hepatocellular carcinoma (HCC) is an ominous complication in patients with liver cirrhosis, there has been no approved drug to prevent the development of HCC to date. We previously reported that the combined treatment of vitamin K2 (VK) and angiotensin-converting enzyme inhibitor (ACE-I) significantly suppressed the experimental hepatocarcinogenesis. A 66-year-old Japanese woman with hepatitis C virus (HCV)-related liver cirrhosis developed a dysplastic nodule in the liver detected by enhanced computed tomography along with elevation of the tumor markers, namely, alpha-fetoprotein (AFP) and lectin-reactive demarcation (AFP-L3), suggesting the presence of latent HCC. After oral administration of VK and ACE-I, the serum levels of both AFP and AFP-L3 gradually decreased without any marked alteration of the serum aminotransferase activity. After one-year treatment, not only the serum levels of AFP and AFP-L3 returned to the normal ranges, but also the dysplastic nodule disappeared. Since both VK and ACE-I are widely used without serious side effects, this combined regimen may become a new strategy for chemoprevention against HCC. | Hitoshi Yoshiji Ryuichi Noguchi Masaharu Yamazaki Yasuhide Ikenaka Masayoshi Sawai Masatoshi Ishikawa Hideto Kawaratani Tsuyoshi Mashitani Mitsuteru Kitade Kosuke Kaji Masahito Uemura Junichi Yamao Masao Fujimoto Akira Mitoro Masahisa Toyohara Motoyuki Yoshida Hiroshi Fukui | 2007 | World Journal of Gastroenterology2007，13，23： | 5 |

| 7 | Eosinophilic cholecystitis along with pericarditis caused by Ascaris lumbricoides: A case report显示文摘Although the etiology of eosinophilic cholecystitis is still obscure, the postulated causes include allergies, parasites, hypereosinophilic syndrome, and eosinophilic gastroenteritis. It is sometimes accompanied by several complications, but a simultaneous onset with pericarditis is very rares. A 28-year-old woman complained of acute right hypocondrial pain and dyspnea associated with systemic eruption. Several imaging modalities revealed acute cholecystitis and pericarditis with massive pericardial effusion. A marked peripheral blood eosinophilia was observed, and the eruption was diagnosed as urticaria. Her serum had a high titer of antibody against Ascaris lumbricoides . Treatment with albendazole drastically improved all clinical manifestations along with normalization of the imaging features and eosinophilia. We report herein a rare case of simultaneous onset of acute cholecystitis and pericarditis associated with a marked eosinophilia caused by parasitic infection. | Kosuke Kaji Hitoshi Yoshiji Masahide Yoshikawa Masaharu Yamazaki Yasuhide Ikenaka Ryuichi Noguchi Masayoshi Sawai Masatoshi Ishikawa Tsuyoshi Mashitani Mitsuteru Kitade Hideto Kawaratani Masahito Uemura Junichi Yamao Masao Fujimoto Akira Mitoro Masahisa Toyohara Motoyuki Yoshida Hiroshi Fukui | 2007 | World Journal of Gastroenterology2007，13，27： | 3 |
| 8 | Enlarged folds on endoscopic gastritis as a predictor for submucosal invasion of gastric cancers显示文摘BACKGROUND Accurate diagnosis of the depth of gastric cancer invasion is crucial in clinical practice.The diagnosis of gastric cancer depth is often made using endoscopic characteristics of the tumor and its margins;however,evaluating invasion depth based on endoscopic background gastritis remains unclear.AIM To investigate predicting submucosal invasion using the endoscopy-based Kyoto classification of gastritis.METHODS Patients with gastric cancer detected on esophagogastroduodenoscopy at Toyoshima Endoscopy Clinic were enrolled.We analyzed the effects of patient and tumor characteristics,including age,sex,body mass index,surveillance endoscopy within 2 years,current Helicobacter pylori infection,the Kyoto classification,and Lauren’s tumor type,on submucosal tumor invasion and curative endoscopic resection.The Kyoto classification included atrophy,intestinal metaplasia,enlarged folds,nodularity,and diffuse redness.Atrophy was characterized by non-reddish and low mucosa.Intestinal metaplasia was detected as patchy whitish or grayish-white flat elevations,forming an irregular uneven surface.An enlarged fold referred to a fold width≥5 mm in the greater curvature of the corpus.Nodularity was characterized by goosebump-like multiple nodules in the antrum.Diffuse redness was characterized by uniform reddish nonatrophic mucosa in the greater curvature of the corpus.RESULTS A total of 266 gastric cancer patients(mean age,66.7 years;male sex,58.6%;mean body mass index,22.8 kg/m2)were enrolled.Ninety-three patients underwent esophagogastroduodenoscopy for surveillance within 2 years,and 140 had current Helicobacter pylori infection.The mean Kyoto score was 4.54.Fifty-eight cancers were diffuse-type,and 87 cancers had invaded the submucosa.Multivariate analysis revealed that low body mass index(odds ratio 0.88,P=0.02),no surveillance esophagogastroduodenoscopy within 2 years(odds ratio 0.15,P<0.001),endoscopic enlarged folds of gastritis(odds ratio 3.39,P=0.001),and Lauren’s diffuse-type(odds ratio 5.09,P<0.001)were independently associated with submucosal invasion.Similar results were obtained with curative endoscopic resection.Among cancer patients with enlarged folds,severely enlarged folds(width≥10 mm)were more related to submucosal invasion than mildly enlarged folds(width 5-9 mm,P<0.001).CONCLUSION Enlarged folds of gastritis were associated with submucosal invasion.Endoscopic observation of background gastritis as well as the lesion itself may help diagnose the depth of cancer invasion. | Osamu Toyoshima Shuntaro Yoshida Toshihiro Nishizawa Akira Toyoshima Kosuke Sakitani Tatsuya Matsuno Tomoharu Yamada Takashi Matsuo Hayato Nakagawa Kazuhiko Koike | 2021 | World Journal of Gastrointestinal Endoscopy2021，13，9： | 2 |

| 10 | Endocytoscopic visualization of squamous cell islands within Barrett's epithelium显示文摘AIM: To study the endocytoscopic visualization of squamous cell islands within Barrett's epithelium. METHODS: Endocytoscopy (ECS) has been studied in the surveillance of Barrett's esophagus, with controversial results. In initial studies, however, a soft catheter type endocytoscope was used, while only methylene blue dye was used for the staining of Barrett's mucosa. Integrated type endocytoscopes (GIF-Q260 EC, Olympus Corp, Tokyo, Japan) have been recently developed, with the incorporation of a high-power magnifying endocytoscope into a standard endoscope together with narrow-band imaging (NBI). Moreover, double staining with a mixture of 0.05% crystal violet and 0.1% of methylene blue (CM) during ECS enables higher quality images comparable to conventional hematoxylin eosin histopathological images.RESULTS: In vivo endocytoscopic visualization of papillary squamous cell islands within glandular Barrett's epithelium in a patient with long-segment Barrett's esophagus is reported. Conventional white light endoscopy showed typical long-segment Barrett's esophagus, with small squamous cell islands within normal Barrett's mucosa, which were better visualized by NBI endoscopy. ECS after double CM staining showed regular Barrett's esophagus, while higher magnification (×480) revealed the orifices of glandular structures better. Furthermore, typical squamous cell papillary protrusion, classified as endocytoscopic atypia classification (ECA) 2 according to ECA, was identified within regular glandular Barrett's mucosa. Histological examination of biopsies taken from the same area showed squamous epithelium within glandular Barrett's mucosa, corresponding well to endocytoscopic findings. CONCLUSION: To our knowledge, this is the first report of in vivo visualization of esophageal papillary squamous cell islands surrounded by glandular Barrett's epithelium. | Nicholas Eleftheriadis Haruhiro Inoue Haruo Ikeda Manabu Onimaru Akira Yoshida Toshihisa Hosoya Roberta Maselli Shin-ei Kudo | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，4： | 2 |

| 16 | Kyoto classification in patients who developed multiple gastric carcinomas after Helicobacter pylori eradication显示文摘BACKGROUND Endoscopic Kyoto classification predicts gastric cancer risk;however,the score in the patients with primary gastric cancer after Helicobacter pylori(H.pylori)eradication therapy is unknown.AIM To elucidate the Kyoto classification score in patients with both single gastric cancer and multiple gastric cancers developed after H.pylori eradication.METHODS The endoscopist recorded the Kyoto classification at the endoscope and the Kyoto classification score at the time of the first diagnosis of gastric cancer after H.pylori eradication.The score was compared between single gastric cancer group and multiple gastric cancers group.RESULTS The Kyoto score at the time of diagnosis of 45 cases of gastric cancer after H.pylori eradication was 4.0 points in average.The score was 3.8 points in the single gastric cancer group,and 5.1 points in the multiple gastric cancers group.The multiple group had a significantly higher score than the single group(P=0.016).In the multiple gastric cancers group,all the patients(7/7)had 5 or higher Kyoto score,while in single gastric cancer group,the proportion of patients with a score of 5 or higher was less than half,or 44.7%(17/38).CONCLUSION Patients diagnosed with gastric cancer after H.pylori eradication tended to have advanced gastritis.In particular,in cases of multiple gastric cancers developed after H.pylori eradication,the endoscopic Kyoto classification score tended to be 5 or higher in patients with an open type atrophic gastritis and the intestinal metaplasia extended to the corpus. | Kosuke Sakitani Toshihiro Nishizawa Akira Toyoshima Shuntaro Yoshida Tatsuya Matsuno Tomoharu Yamada Masatoshi Irokawa Yoshiyuki Takahashi Yousuke Nakai Osamu Toyoshima Kazuhiko Koike | 2020 | World Journal of Gastrointestinal Endoscopy2020，12，9： | 2 |
| 17 | 日本东部内陆地区2011年大地震前后的应力状态与诱发地震显示文摘通过反演震源机制数据,得到了东日本大地震前后日本东部内陆地区的应力场。地震前,在东北部(Tohoku),σ1轴呈EW方向,但在关东-东部(Kanto-Chubu)地区则呈NW-SE方向。地震后,在Tohoku北部和靠近磐城市(Iwaki City)的Tohoku东南部,应力场发生了变化,主应力取向大致等同于与地震相关的静应力变化取向。这说明地震前这些地区的差应力值小于1MPa。在Tohoku中部,虽然地震后加载的应力取向几乎逆转,但其应力场没有发生变化,说明那里的差应力值大大超过1MPa。在Kanto-Chubu,地震后加载了与背景应力方向近乎相同的应力,且应力场没有发生预期的变化。这可能就是Kanto-Chubu地区高地震活动水平的诱因。 | Keisuke Yoshida Akira Hasegawa Tomomi Okada Takeshi Iinuma Yoshihiro Ito Youichi Asano 洪启宇 | 2012 | 国际地震动态2012，，4： | 2 |
