| 1 | Nonalcoholic fatty liver disease is a novel predictor of cardiovascular disease显示文摘AIM:To clarify whether nonalcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular disease.METHODS:We carried out a prospective observational study with a total of 1637 apparently healthy Japanese men and women who were recruited from a health check-up program.NAFLD was diagnosed by abdominal ultrasonography.The metabolic syndrome(MS)was defined according to the modified National Cholesterol Education Program(NCEP)ATP Ⅲ criteria.Five years after the baseline evaluations,the incidence of cardiovascular disease was assessed by a self-administered questionnaire.RESULTS:Among 1221 participants available for outcome analyses,the incidence of cardiovascular disease was higher in 231 subjects with NAFLD at baseline(5 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage)than 990 subjects without NAFLD(3 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage).Multivariate analyses indicated that NAFLD was a predictor of cardiovascular disease independent of conventional risk factors(odds ratio 4.12,95% CI,1.58 to 10.75,P = 0.004).MS was alsoindependently associated with cardiovascular events.But simultaneous inclusion of NAFLD and MS in a multivariate model revealed that NAFLD but not MS retained a statistically significant correlation with cardiovascular disease.CONCLUSION:Although both of them were predictors of cardiovascular disease,NAFLD but not MS retained a statistically significant correlation with cardiovascular disease in a multivariate model.NAFLD is a strong predictor of cardiovascular disease and may play a central role in the cardiovascular risk of MS. | Masahide Hamaguchi Takao Kojima Noriyuki Takeda Chisato Nagata Jun Takeda Hiroshi Sarui Yutaka Kawahito Naohisa Yoshida Atsushi Suetsugu Takahiro Kato Junichi Okuda Kazunori Ida Toshikazu Yoshikawa | 2007 | World Journal of Gastroenterology2007,13,10: | 55 |

| 3 | Anti-inflammatory activity of probiotic Bifidobacterium: Enhancement of IL-10 production in peripheral blood mononuclear cells from ulcerative colitis patients and inhibition of IL-8 secretion in HT-29 cells显示文摘AIM: To determine the anti-inflammatory activity of probiotic Bifidobacteria in Bifidobacteria-fermented milk (BFM) which is effective against active ulcerative colitis (UC) and exacerbations of UC, and to explore the immunoregulatory mechanisms. METHODS: Peripheral blood mononuclear cells (PBMNC) from UC patients or HT-29 cells were co-cultured with heat-killed probiotic bacteria or culture supernatant of Bifidobacterium breve strain Yakult (BbrY) or Bifidobacterium bifidum strain Yakult (BbiY) to estimate the amount of IL-10 or IL-8 secreted. RESULTS: Both strains of probiotic Bifidobacteria contained in the BFM induced IL-10 production in PBMNC from UC patients, though BbrY was more effective than BbiY. Conditioned medium (CM) and DNA of both strains inhibited IL-8 secretion in HT-29 cells stimulated with TNF-α, whereas no such effect was observed with heat- killed bacteria. The inhibitory effect of CM derived from BbiY was greater than that of CM derived from BbrY. DNAs of the two strains had a comparable inhibitory activity against the secretion of IL-8. CM of BbiY induced a repression of IL-8 gene expression with a higher expression of IκB-ζ mRNA 4 h after culture of HT-29 cells compared to that in the absence of CM.CONCLUSION: Probiotic Bifidobacterium strains in BFM enhance IL-10 production in PBMNC and inhibit IL-8 secretion in intestinal epithelial cells, suggesting that BFM has anti-inflammatory effects against ulcerative colitis. | Akemi Imaoka Tatsuichiro Shima Kimitoshi Kato Shigeaki Mizuno Toshiki Uehara Satoshi Matsumoto Hiromi Setoyama Taeko Hara Yoshinori Umesaki | 2008 | World Journal of Gastroenterology2008,14,16: | 37 |

| 6 | Petawatt and exawatt class lasers worldwide显示文摘In the 2015 review paper‘Petawatt Class Lasers Worldwide’a comprehensive overview of the current status of highpower facilities of>200 TW was presented.This was largely based on facility specifications,with some description of their uses,for instance in fundamental ultra-high-intensity interactions,secondary source generation,and inertial confinement fusion(ICF).With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification(CPA),which made these lasers possible,we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed.We are now in the era of multi-petawatt facilities coming online,with 100 PW lasers being proposed and even under construction.In addition to this there is a pull towards development of industrial and multi-disciplinary applications,which demands much higher repetition rates,delivering high-average powers with higher efficiencies and the use of alternative wavelengths:mid-IR facilities.So apart from a comprehensive update of the current global status,we want to look at what technologies are to be deployed to get to these new regimes,and some of the critical issues facing their development. | Colin N.Danson Constantin Haefner Jake Bromage Thomas Butcher Jean-Christophe FChanteloup Enam A.Chowdhury Almantas Galvanauskas Leonida A.Gizzi Joachim Hein David I.Hillier Nicholas W.Hopps Yoshiaki Kato Efim A.Khazanov Ryosuke Kodama Georg Korn Ruxin Li Yutong Li Jens Limpert Jingui Ma Chang Hee Nam David Neely Dimitrios Papadopoulos Rory R.Penman Liejia Qian Jorge J.Rocca andrey A.Shaykin Craig W.Siders Christopher Spindloe Sándor Szatmári Raoul M.G.M.Trines Jianqiang Zhu Ping Zhu Jonathan D.Zuegel | 2019 | High Power Laser Science and Engineering2019,7,3: | 33 |
| 7 | Environmental Problems From Tea Cultivation in Japan and a Control Measure Using Calcium Cyanamide显示文摘A field experiment, involving lime N (calcium cyanamide, CaCN2) fertilization as a control measure, was conducted to study environmental problems induced by long-term heavy N application in Japanese tea fields. Long-term tea cultivation caused serious soil acidification. Seventy-seven percent of the 70 tea fields investigated had soil pH values below 4.0, and 9% below 3.0, with the lowest value of 2.7. Moreover, excess N application in tea fields put a threat to plant growth, induced serious nitrate contamination to local water, and caused high nitrous oxide loss. Compared with the conventional high N application treatment (1100 kg N ha-1) without lime N, the low N application (400 kg N ha-1) with calcium cyanamide effectively stopped soil acidification as well as achieved the same or slightly higher levels in tea yield and in total N and amino acid contents of tea shoots. The application of calcium cyanamide could be a suitable fertilization for the prevention of environmental problems in tea cultivation. | K. OH T.

| 8 | Helicobacter pylori-related chronic gastritis as a risk factor for colonic neoplasms显示文摘To summarize the current views and insights on associations between Helicobacter pylori(H. pylori)-related chronic gastritis and colorectal neoplasm, we reviewed recent studies to clarify whether H. pylori infection/H. pylori-related chronic gastritis is associated with an elevated risk of colorectal neoplasm. Recent studies based on large databases with careful control for confounding variables have clearly demonstrated an increased risk of colorectal neoplasm associated with H. pylori infection. The correlation between H. pylori-related chronic atrophic gastritis(CAG) and colorectal neoplasm has only been examined in a limited number of studies. A recent large study using a national histopathological database, and our study based on the stage of H. pylori-related chronic gastritis as determined by serum levels of H. pylori antibody titer and pepsinogen, indicatedthat H. pylori-related CAG confers an increased risk of colorectal neoplasm, and more extensive atrophic gastritis will probably be associated with even higher risk of neoplasm. In addition, our study suggested that the activity of H. pylori-related chronic gastritis is correlated with colorectal neoplasm risk. H. pylori-related chronic gastritis could be involved in an increased risk of colorectal neoplasm that appears to be enhanced by the progression of gastric atrophy and the presence of active inflammation. | Izumi Inoue Jun Kato Hideyuki Tamai Mikitaka Iguchi Takao Maekita Noriko Yoshimura Masao Ichinose | 2014 | World Journal of Gastroenterology2014,20,6: | 25 |
| 9 | Single-incision laparoscopic cholecystectomy:Single institution experience and literature review显示文摘Single-incision laparoscopic surgery is a rapidly evolving field as a bridge between traditional laparoscopic surgery and natural orifice transluminal endoscopic surgery.We report one of the initial clinical experiences in Japan with this new technique.Four cases of gallbladder diseases were selected for this new technique.A single curved intra-umbilical 25-mm incision was made by pulling out the umbilicus.A 12-mm trocar was placed through an open approach,and the abdominal cavity was explored with a 10-mm semiflexible laparoscope.Two 5-mm ports were inserted laterally from the laparoscope port.A 2-mm mini-loop retractor was inserted to retract the fundus of the gallbladder.Dissection was performed using an electric cautery hook and an Endograsper roticulator.There were two women and two men with a mean age of 50.5 years(range:40-61 years).All procedures were completed successfully without any perioperative complications.In all cases,there was no need to extend the skin incision.Average operative time was 88.8 min.Postoperative follow-up didnot reveal any umbili-cal wound complication.Single-incision laparoscopic cholecystectomy is feasible and a promising alternative method as scarless abdominal surgery for the treatment of some patients with gallbladder disease. | Yasumitsu Hirano Toru Watanabe Tsuneyuki Uchida Shuhei Yoshida Kanae Tawaraya Hideaki Kato Osamu Hosokawa | 2010 | World Journal of Gastroenterology2010,16,2: | 23 |

| 11 | Aging is a risk factor of nonalcoholic fatty liver disease in premenopausal women显示文摘AIM: To clarify the relationship between age, menopause, and nonalcoholic fatty liver disease (NAFLD) in women. METHODS: We conducted a follow-up study on non-alcoholic fatty liver disease by using abdominal ultrasonography, and investigated the relationship of age and menopause with the development of NAFLD in women. We followed 1829 women and 2572 men (response rate, 86%) selected in 2001 to represent the non-institutionalized adult population of Gifu, Japan. Data collected included self-reported medical history, lifestyle factors, and menopausal status. The postmenopausal state was defined as beginning 1 year after the cessation of menses. We diagnosed NAFLD with the aid of abdominal ultrasonography by using diagnostic criteria describedRESULTS: The prevalence of NAFLD in women increases with age, but does not alter with age in men. Furthermore, the prevalence of NAFLD in premenopausal women (6%) was lower than that in men (24%) and in postmenopausal women (15%). The associations of the postmenopausal state and hormone replacement therapy with NAFLD were statistically significant in a univariate logistic regression model. At the follow-up examination, 67 women (5%) were newly diagnosed with NAFLD. The incidence of NAFLD was 3.5% (28/802) in premenopausal women, 7.5% (4/53) in menopausal women, 6.1% (24/392) in postmenopausal women, and 5.3% (11/206) in women receiving hormone replacement therapy. The weight gain in premenopausal women was equal to that in postmenopausal women. Metabolic syndrome and weight gain were independent risk factors for NAFLD in pre-and postmenopausal women, but age was an independent risk factor in premenopausal women only. CONCLUSION: Aging is a risk factor for NAFLD in premenopausal women, independent of weight gain or influence of metabolic syndrome. | Masahide Hamaguchi Takao Kojima Akihiro Ohbora Noriyuki Takeda Michiaki Fukui Takahiro Kato | 2012 | World Journal of Gastroenterology2012,18,3: | 19 |
| 12 | Specific endoscopic features of ulcerative colitis complicated by cytomegalovirus infection显示文摘AIM:To identify specific colonoscopic findings in patients with ulcerative colitis (UC) complicated by cyto-megalovirus (CMV) infection.METHODS: Among UC patients who were hospitalized due to exacerbation of symptoms, colonoscopic findings were compared between 15 CMV-positive patients and 58 CMV-negative patients. CMV infection was determined by blood test for CMV antigenemia. Five aspects of mucosal changes were analyzed (loss of vascular pattern, erythema, mucosal edema, easy bleeding, and mucinous exudates) as well as five aspects of ulcerative change (wide mucosal defect, punched-out ulceration, longitudinal ulceration, irregular ulceration, and cobble-stone-like appearance). Sensitivity, specificity, positive predictive value, and negative predictive value of each finding for CMV positivity were determined.RESULTS: The sensitivity of irregular ulceration for positive CMV was 100%. The specificity of wide mucosal defect was 95%. Punched-out ulceration and lon-gitudinal ulceration exhibited relatively high sensitivity and specificity (more than 70% for each).CONCLUSION:Specific colonoscopic findings in patients with UC complicated by CMV infection were identified. These findings may facilitate the early diagnosis of CMV infection in UC patients. | Hideyuki Suzuki Jun Kato Motoaki Kuriyama Sakiko Hiraoka Kenji Kuwaki Kazuhide Yamamoto | 2010 | World Journal of Gastroenterology2010,16,10: | 19 |
| 13 | Diagnosis and therapies for gastric non-invasive neoplasia显示文摘There has been a great discrepancy of pathological diagnosis for gastric non-invasive neoplasia/dysplasia between Japanese and western pathologists. In Japan, lesions that most western pathologists diagnose as dysplasia are often considered adenocarcinoma based on nuclear and structural atypia regardless of the presence of invasion. In the Vienna classification, gastric non-invasive intraepithelial neoplasia(NIN) weredivided into low grade and high grade(including intramucosal cancer of Japanese criteria). The diagnosis by both endoscopy and pathology of biopsy specimen is difficult. Recent advances of diagnostic modality such as magnified endoscopy and imaged enhanced endoscopy is expected to improve the diagnostic yield for NIN. There are two treatment strategies for NIN, observation and diagnostic therapy by endoscopic resection(ER). ER is acceptable because of its less invasiveness and high local control rate, on the other hand, cancer-developing rate of low-grade NIN is reported to be low. Therefore there is controversy for the treatment of gastric NIN. Prospective study based on unified pathological definition is required in the future. | Motohiko Kato | 2015 | World Journal of Gastroenterology2015,21,44: | 18 |
| 14 | Laparoscopic appendectomy for acute appendicitis: How to discourage surgeons using inadequate therapy显示文摘Acute appendicitis(AA) develops in a progressive and irreversible manner, even if the clinical course of AA can be temporarily modified by intentional medications. Reliable and real-time diagnosis of AA can be made based on findings of the white blood cell count and enhanced computed tomography. Emergent laparoscopic appendectomy(LA) is considered as the first therapeutic choice for AA. Interval/delayed appendectomy at 6-12 wk after disease onset is considered as unsafe with a high recurrent rate during the waiting time. However, this technique may have some advantages for avoiding unnecessary extended resection in patients with an appendiceal mass. Nonoperative management of AA may be tolerated only in children. Postoperative complications increase according to the patient's factors, and temporal avoidance of emergent general anesthesia may be beneficial for high-risk patients. The surgeon's skill and cooperation of the hospital are important for successful LA. Delaying appendectomy for less than 24 h from diagnosis is safe. Additionally, a semi-elective manner(i.e., LA within 24 h after onset of symptoms) may be paradoxically acceptable, according to the factors of the patient, physician, and institution. Prompt LA is mandatory for AA. Fortunately, the Japanese government uses a universal health insurance system, which covers LA. | tomohide hori takafumi machimoto yoshio kadokawa toshiyuki hata tatsuo ito shigeru kato daiki yasukawa yuki aisu yusuke kimura maho sasaki yuichi takamatsu taku kitano shigeo hisamori tsunehiro yoshimura | 2017 | World Journal of Gastroenterology2017,23,32: | 18 |
| 15 | 为胃的癌症的内视镜的 submucosal 解剖的支持的技术和设备显示文摘 The indications for endoscopic treatment have expanded in recent years,and relatively intestinal-type mucosal stomach carcinomas with a low potential for metastasis are now often resected en bloc by endoscopic submucosal dissection(ESD),even if they measure over 20 mm in size.However,ESD requires complex maneuvers,which entails a long operation time,and is often accompanied by complications such as bleeding and perforation.Many technical developments have been implemented to overcome these complications.The scope,cutting device,hemostasis device,and other supportive devices have been improved.However,even with these innovations,ESD remains a potentially complex procedure.One of the major difficulties is poor visualization of the submucosal layer resulting from the poor countertraction afforded during submucosal dissection.Recently,countertraction devices have been developed.In this paper,we introduce countertraction techniques and devices mainly for gastric cancer. | Nobuyuki Sakurazawa Shunji Kato Itsuo Fujita Yoshikazu Kanazawa Hiroyuki Onodera Eiji Uchida | 2012 | World Journal of Gastrointestinal Endoscopy2012,4,6: | 18 |
| 16 | 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 |
| 17 | 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 |
| 18 | Impact of endoscopic screening on mortality reduction from gastric cancer显示文摘AIM:To investigate mortality reduction from gastric cancer based on the results of endoscopic screening.METHODS:The study population consisted of participants of gastric cancer screening by endoscopy,regular radiography,and photofluorography at Niigata city in 2005.The observed numbers of cumulative deaths from gastric cancers and other cancers were accumulated by linkage with the Niigata Prefectural Cancer Registry.The standardized mortality ratio(SMR)of gastric cancer and other cancer deaths in each screening group was calculated by applying the mortality rate of the reference population.RESULTS:Based on the results calculated from the mortality rate of the population of Niigata city,the SMRs of gastric cancer death were 0.43(95%CI:0.30-0.57)for the endoscopic screening group,0.68(95%CI:0.55-0.79)for the regular radiographic screening group,and 0.85(95%CI:0.71-0.94)for the photofluorography screening group.The mortality reduction from gastric cancer was higher in the endoscopic screening group than in the regular radiographic screening group despite the nearly equal mortality rates of all cancers except gastric cancer.CONCLUSION:The 57%mortality reduction from gastric cancer might indicate the effectiveness of endoscopic screening for gastric cancer.Further studies and prudent interpretation of results are needed. | Chisato Hamashima Kazuei Ogoshi Rintarou Narisawa Tomoki Kishi Toshiyuki Kato Kazutaka Fujita Masatoshi Sano Satoshi Tsukioka | 2015 | World Journal of Gastroenterology2015,21,8: | 16 |

| 20 | Gut microbiota,inflammation and colorectal cancer显示文摘Although genes contribute to colorectal cancer,the gut microbiota are an important player.Accumulating evidence suggests that chronic infection and the ensuing inflammation contributes to tumor initiation and tumor progression.A variety of bacterial species and tumor-promoting virulence mechanisms have been investigated.Significant advances have been made in understanding the composition and functional capabilities of the gut microbiota and its roles in cancer.In the current review,we discuss the novel roles of microbiota in the progression of colon cancer.Although microbiota technically include organisms other than bacteria e.g.,viruses and fungi,this review will primarily focus on bacteria.We summarize epidemiological studies of human microbiome and colon cancer.We discuss the progress in the scientific understanding of the interplay between the gut microbiota,barrier function,and host responses in experimental models.Further,we discuss the potential application in prevention,diagnosis,and therapy of colon cancer by targeting microbiota.We discuss the challenges lie ahead and the future direction in studying gut microbiome in colon cancer to close the gap between the basic sciences and clinical application. | Jun Sun Ikuko Kato | 2016 | Genes & Diseases2016,3,2: | 16 |
