| 1 | Review of the diagnosis and management of gastrointestinal bezoars显示文摘The formation of a bezoar is a relatively infrequentdisorder that affects the gastrointestinal system.Bezoars are mainly classified into four types dependingon the material constituting the indigestible mass of thebezoar phytobezoars, trichobezoars, pharmacobezoars,and lactobezoars. Gastric bezoars often cause ulcerativelesions in the stomach and subsequent bleeding,whereas small intestinal bezoars present with smallbowel obstruction and ileus. A number of articles haveemphasized the usefulness of Coca-Cola? administrationfor the dissolution of phytobezoars. However, persimmonphytobezoars may be resistant to such dissolutiontreatment because of their harder consistency comparedto other types of phytobezoars. Better understanding ofthe etiology and epidemiology of each type of bezoarwill facilitate prompt diagnosis and management.Here we provide an overview of the prevalence, classification,predisposing factors, and manifestations ofbezoars. Diagnosis and management strategies arealso discussed, reviewing mainly our own case series.Recent progress in basic research regarding persimmonphytobezoars is also briefly reviewed. | Masaya Iwamuro Hiroyuki Okada Kazuhiro Matsueda Tomoki Inaba Chiaki Kusumoto Atsushi Imagawa Kazuhide Yamamoto | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，4： | 22 |
| 2 | 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 |
| 3 | Intraductal neoplasm of the intrahepatic bile duct: Clinicopathological study of 24 cases显示文摘AIM: To investigate the clinicopathological features of intraductal neoplasm of the intrahepatic bile duct (INihB). METHODS: Clinicopathological features of 24 cases of INihB, which were previously diagnosed as biliary papillomatosis or intraductal growth of intrahepatic biliary neoplasm, were reviewed. Mucin immunohistochemistry was performed for mucin (MUC)1, MUC2, MUC5AC and MUC6. Ki-67, P53 and β-catenin immunoreactivity were also examined. We categorized each tumor as adenoma (low grade), borderline (intermediate grade), and malignant (carcinoma in situ , high grade including tumors with microinvasion). RESULTS: Among 24 cases of INihB, we identified 24 tumors. Twenty of 24 tumors (83%) were composed of a papillary structure; the same feature observed in intraductal papillary neoplasm of the bile duct (IPNB). In contrast, the remaining four tumors (17%) showed both tubular and papillary structures. In three of the four tumors (75%), macroscopic mucin secretion was limited but microscopic intracellular mucin was evident. Histologically, 16 tumors (67%) were malignant, three (12%) were borderline, and five (21%) were adenoma. Microinvasion was found in four cases (17%). Immunohistochemical analysis revealed that MUC1 was not expressed in the borderline/adenoma group but was expressed only in malignant lesions (P = 0.0095). Ki-67 labeling index (LI) was significantly higher in the malignant group than in the borderline/adenoma group (22.2 ± 15.5 vs 7.5 ± 6.3, P < 0.01). In the 16 malignant cases, expression of MUC5AC showed borderline significant association with high Ki-67 LI (P = 0.0622). Nuclear expression of β-catenin was observed in two (8%) of the 24 tumors, and these two tumors also showed MUC1 expression. P53 was negative in all tumors. CONCLUSION: Some cases of INihB have a tubular structure, and are subcategorized as IPNB with tubular structure. MUC1 expression in INihB correlates positively with degree of malignancy. | Yoshiki Naito Hironori Kusano Osamu Nakashima Eiji Sadashima Satoshi Hattori Tomoki Taira Akihiko Kawahara Yoshinobu Okabe Kazuhide Shimamatsu Jun Taguchi Seiya Momosaki Koji Irie Rin Yamaguchi Hiroshi Yokomizo Michiko Nagamine Seiji Fukuda Shinichi Sugiyama Naoyo Nishida Koichi Higaki Munehiro Yoshitomi Masafumi Yasunaga Koji Okuda Hisafumi Kinoshita Masayoshi Kage Masamichi Nakayama Makiko Yasumoto Jun Akiba Hirohisa Yano | 2012 | World Journal of Gastroenterology2012，18，28： | 16 |
| 4 | Patients with early recurrence of hepatocellular carcinoma have poor prognosis显示文摘BACKGROUND: Early recurrence(ER) after hepatic resection(HR) is a poor prognostic factor for patients with hepatocellular carcinoma(HCC). This study aimed to identify the clinicopathological features, outcomes, and risk factors for ER after HR for small HCC in order to clarify the reasons why ER is a worse recurrence pattern.METHODS: We retrospectively examined 130 patients who underwent HR for small HCC(≤30 mm). Recurrence was classified into ER(<2 years) and late recurrence(LR)(≥2 years). The clinicopathological features, outcomes, and risk factors for ER were analyzed by multivariate analysis.RESULTS: ER was observed in 39 patients(30.0%). The survival rate of the ER group was significantly lower than that of the LR group(P<0.005), and ER was an independent prognostic factor for poor survival(P=0.0001). The ER group had a significantly higher frequency(P=0.0039) and shorter interval(P=0.027) of development to carcinoma beyond the Milan criteria(DBMC) compared with the LR group, and ER was an independent risk factor for DBMC(P<0.0001). Multi-nodularity, non-simple nodular type, and microvascular invasion were independent predictors for ER(P=0.012, 0.010, and 0.019, respectively).CONCLUSIONS: ER was a highly malignant recurrence pattern associated with DBMC and subsequent poor survival after HR for small HCC. Multi-nodularity, non-simple nodular type, and microvascular invasion predict ER, and taking these factors into consideration may be useful for the decision of the treatment strategy for small HCC after HR. | Tomoki Kobayashi Hiroshi Aikata Tsuyoshi Kobayashi Hideki Ohdan Koji Arihiro Kazuaki Chayama | 2017 | Hepatobiliary & Pancreatic Diseases International2017，16，3： | 15 |
| 5 | Colorectal endoscopic submucosal dissection: Recent technical advances for safe and successful procedures显示文摘Endoscopic submucosal dissection(ESD) is very useful in en bloc resection of large superficial colorectal tumors but is a technically difficult procedure because the colonic wall is thin and endoscopic maneuverability is poor because of colonic flexure and extensibility. A high risk of perforation has been reported in colorectal ESD. To prevent complications such as perforation and unexpected bleeding, it is crucial to ensure good visualization of the submucosal layer by creating a mucosal flap, which is an exfoliated mucosa for inserting the tip of the endoscope under it. The creation of a mucosal flap is often technically difficult; however, various types of equipment, appropriate strategy, and novel procedures including our clip-flap method, appear to facilitate mucosal flap creation, improving the safety and success rate of ESD. Favorable treatment outcomes with colorectal ESD have already been reported in many advanced institutions, and appropriate understanding of techniques and development of training systems are required for world-wide standardization of colorectal ESD. Here, we describe recent technical advances for safe and successful colorectal ESD. | Katsumi Yamamoto Tomoki Michida Tsutomu Nishida Shiro Hayashi Masafumi Naito Toshifumi Ito | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，14： | 9 |
| 6 | Progress in researches about focal adhesion kinase in gastrointestinal tract显示文摘Focal adhesion kinase(FAK)is a 125-kDa non-receptor protein tyrosine.Growth factors or the clustering of integrins facilitate the rapid phosphorylation of FAK at Tyr-397 and this in turn recruits Src-family protein tyrosine kinases,resulting in the phosphorylation of Tyr-576 and Tyr-577 in the FAK activation loop and full catalytic FAK activation.FAK plays a critical role in the biological processes of normal and cancer cells including the gastrointestinal tract.FAK also plays an important role in the restitution,cell survival and apoptosis and carcinogenesis of the gastrointestinal tract.FAK is over-expressed in cancer cells and its over-expression and elevated activities are associated with motility and invasion of cancer cells.FAK has been proposed as a potential target in cancer therapy.Small molecule inhibitors effectively inhibit the kinase activity of FAK and show a potent inhibitory effect for the proliferation and migration of tumor cells,indicating a high potential for application in cancer therapy. | Hui Fang Hao Yoshio Naomoto Xiao-Hong Bao Nobuyuki Watanabe Kazufumi Sakurama Kazuhiro Noma Yasuko Tomono Takuya Fukazawa Yasuhiro Shirakawa Tomoki Yamatsuji Junji Matsuoka Munenori Takaoka | 2009 | World Journal of Gastroenterology2009，15，47： | 8 |

| 13 | Glutamine depletion induces murine neonatal melena with increased apoptosis of the intestinal epithelium显示文摘AIM:To investigate the possible biological outcome and effect of glutamine depletion in neonatal mice and rodent intestinal epithelial cells.METHODS:We developed three kinds of artificial milk with different amounts of glutamine;Complete amino acid milk (CAM),which is based on maternal mouse milk,glutamine-depleted milk (GDM),and glutaminerich milk (GRM).GRM contains three-fold more glutamine than CAM.Eighty-seven newborn mice were divided into three groups and were fed with either of CAM,GDM,or GRM via a recently improved nipple-bottle system for seven days.After the feeding period,the mice were subjected to macroscopic and microscopic observations by immunohistochemistry for 5-bromo-2'deoxyuridine (BrdU) and Ki-67 as markers of cell proliferation,and for cleaved-caspase-3 as a marker of apoptosis.Moreover,IEC6 rat intestinal epithelial cells were cultured in different concentrations of glutamine and were subject to a 4-[3-(4-iodophenyl)-2-(4-nitrophenyl)2H-5-tetrazolio]-1,3-benzene disulfonate cell proliferation assay,flow cytometry,and western blotting to examine the biological effect of glutamine on cell growth and apoptosis.RESULTS:During the feeding period,we found colonic hemorrhage in six of 28 GDM-fed mice (21.4%),but not in the GRM-fed mice,with no differences in body weight gain between each group.Microscopic examination showed destruction of microvilli and the disappearance of glycocalyx of the intestinal wall in the colon epithelial tissues taken from GDM-fed mice.Intake of GDM reduced BrdU incorporation (the average percentage of BrdU-positive staining;GRM:13.8%,CAM:10.7%,GDM:1.14%,GRM vs GDM:P < 0.001,CAM vs GDM:P < 0.001) and Ki-67 labeling index (the average percentage of Ki67-positive staining;GRM:24.5%,CAM:22.4% GDM:19.4%,GRM vs GDM:P=0.001,CAM vs GDM:P =0.049),suggesting that glutamine depletion inhibited cell proliferation of intestinal epithelial cells.Glutamine deprivation further caused the deformation of the nuclear membrane and the plasma membrane,accompanied by chromatin degeneration and an absence of fat droplets from the colonic epithelia,indicating that the cells underwent apoptosis.Moreover,immunohistochemical analysis revealed the appearance of cleaved caspase-3 in colonic epithelial cells of GDM-fed mice.Finally,when IEC6 rat intestinal epithelial cells were cultured without glutamine,cell proliferation was significantly suppressed after 24 h (relative cell growth;4 mmol/L:100.0% ± 36.1%,0 mmol/L:25.3% ± 25.0%,P < 0.05),with severe cellular damage.The cells underwent apoptosis,accompanied by increased cell population in sub-G0 phase (4 mmol/L:1.68%,0.4 mmol/L:1.35%,0 mmol/L:5.21%),where dying cells are supposed to accumulate.CONCLUSION:Glutamine is an important alimentary component for the maintenance of intestinal mucosa.Glutamine deprivation can cause instability of the intestinal epithelial alignment by increased apoptosis. | Takayuki Motoki Yoshio Naomoto Junji Hoshiba Yasuhiro Shirakawa Tomoki Yamatsuji Junji Matsuoka Munenori Takaoka Yasuko Tomono Yasuhiro Fujiwara Hiroshi Tsuchita Mehmet Gunduz Hitoshi Nagatsuka Noriaki Tanaka Toshiyoshi Fujiwara | 2011 | World Journal of Gastroenterology2011，17，6： | 4 |
| 14 | 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 |
| 15 | A novel experimental method to evaluate the impact of volute's asymmetry on the performance of a high pressure ratio turbocharger compressor显示文摘All components of a turbocharger compressor are axisymmetric except for the spiral-shaped,gas-collecting overhung volute.In this paper,a novel experimental method to evaluate the impact of the volute's asymmetry on centrifugal compressor performance is proposed and applied to a high pressure-ratio turbocharger compressor.This method can isolate the impact of the volute's asymmetry on the compressor performance for the first time.Experiments prove the considerable impact of the volute's asymmetry on the compressor performance,especially the stability and efficiency.The impact of the volute's asymmetry on compressor stability correlates with rotational speed and thus with the pressure ratio,constricting the stable flow range by up to 47 percent and decreasing the maximum efficiency by 4.8 percent at the design speed.The results provide evidence to exploit the potential of intrinsic non-axisymmetric flow induced by asymmetric volute to improve the performance of turbocharger compressor with a high pressure ratio. | LIN Yun ZHENG XinQian JIN Lei TAMAKI Hideaki KAWAKUBO Tomoki | 2012 | Science China(Technological Sciences)2012，55，6： | 4 |
| 16 | Serum Mac-2 binding protein is a novel biomarker for chronic pancreatitis显示文摘AIM: To determine the efficacy of Mac-2 binding protein(Mac-2bp) for diagnosis of chronic pancreatitis.METHODS: Fifty-nine healthy volunteers(HV), 162 patients with chronic pancreatitis(CP), and 94 patients with pancreatic ductal adenocarcinoma(PDAC) were enrolled in this study. We measured serum Mac-2bp using our developed enzyme-linked immunosorbent assay kit. Additional biochemical variables were measured using an automated analyzer(including aminotransferase, alanine aminotransferase, γ-glutamyltransferase, alkaline phosphatase, triglyceride, C-reactive protein, and amylase levels) or chemiluminescent enzyme immunoassay(carbohydrate antigen 19-9 and carcinoembryonic antigen). The ability of Mac-2bp to predict CP diagnosis accurately was assessed using receiver operating characteristic(ROC) analyses.RESULTS: Serum Mac-2bp levels were significantly increased in CP patients compared to HV(P < 0.0001) and PDAC patients(P < 0.0001). Area under the ROC curve values of Mac-2bp for the discrimination of CP from HV and PDAC were 0.727 and 0.784, respectively. Multivariate analyses demonstrated that serum Mac-2bp levels were independent determinants for CP diagnosis from HV and PDAC patients. Immunohistological staining showed that Mac-2bp was expressed faintly in the pancreas tissues of both CP and PDAC patients. Serum aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, alkaline phosphatase, and triglyceride levels were significantly higher in patients with CP or PDAC. Serum Mac-2bp levels were highly correlated with protein levels of alanine aminotransferase, γ-glutamyltransferase, and C-reactive protein, but not amylase, suggesting that the damaged liver produces Mac-2bp. CONCLUSION: Measurement of serum Mac-2bp may be a novel and useful biomarker for CP diagnosis as well as liver fibrosis in the general population. | Tomohiro Maekawa Yoshihiro Kamada Yusuke Ebisutani Makiko Ueda Tomoki Hata Koichi Kawamoto Shinji Takamatsu Kayo Mizutani Mayuka Shimomura Tomoaki Sobajima Hironobu Fujii Kotarosumitomo Nakayama Kimihiro Nishino Makoto Yamada Takashi Kumada Toshifumi Ito Hidetoshi Eguchi Hiroaki Nagano Eiji Miyoshi | 2016 | World Journal of Gastroenterology2016，22，17： | 3 |
| 17 | Factors associated with complicated erosive esophagitis: A Japanese multicenter, prospective, cross-sectional study显示文摘AIM To assess the clinical characteristics of patients with complicated erosive esophagitis(EE) and their associated factors.METHODS This prospective, cross-sectional study included patients diagnosed with EE by upper gastrointestinal endoscopy between October 2014 and March 2015 at 106 Japanese hospitals. Data on medical history, general condition, gastrointestinal symptoms, lifestyle habits, comorbidities, and endoscopic findings were collected using a standard form to create a dedicated database. Logistic regression analysis was used to calculate adjusted odds ratios(aO R) and 95%CI for the association with complicated EE.RESULTS During the study period, 1749 patients diagnosed with EE, 38.3% of whom were prescribed proton pump inhibitors(PPIs) were included. Of them, 143(8.2%) had EE complications. Esophageal bleeding occurred in 84(4.8%) patients, esophageal strictures in 45(2.6%) patients, and 14(0.8%) patients experienced both. Multivariate analysis showed that increased age(a OR: 1.05; 95%CI: 1.03-1.08), concomitant use of psychotropic agents(a OR: 6.51; 95%CI: 3.01-13.61), and Los Angeles grades B(a OR: 2.69; 95%CI: 1.48-4.96), C(aO R: 15.38; 95%CI: 8.62-28.37), and D(aO R: 71.49; 95%CI: 37.47-142.01) were significantly associated with complications, whereas alcohol consumption 2-4 d/wk was negatively associated(a OR: 0.23; 95%CI: 0.06-0.61). Analyzing associated factors with each EE complication separately showed esophageal ulcer bleeding were associated with increased age(a OR: 1.05; 95%CI: 1.02-1.07) and Los Angeles grades B(aO R: 3.60; 95%CI: 1.52-8.50), C(a OR: 27.61; 95%CI: 12.34-61.80), and D(a OR: 119.09; 95%CI: 51.15-277.29), while esophageal strictures were associated with increased age(a OR: 1.07; 95%CI: 1.04-1.10), gastroesophageal reflux symptom(aO R: 2.51; 95%CI: 1.39-4.51), concomitantuse of psychotropic agents(a OR: 11.79; 95%CI: 5.06-27.48), Los Angeles grades C(aO R: 7.35; 95%CI: 3.32-16.25), and D(a OR: 20.34; 95%CI: 8.36-49.53) and long-segment Barrett's esophagus(a OR: 4.63; 95%CI: 1.64-13.05).CONCLUSION Aging and severe EE were common associated factors, although there were more associated factors in esophageal strictures than esophageal ulcer bleeding. Despite the availability and widespread use of PPIs, EE complications are likely to remain a problem in Japan owing to the aging population and high-stress society. | Masahiro Sakaguchi Noriaki Manabe Nobuo Ueki Jun Miwa Tomoki Inaba Norimasa Yoshida Kouichi Sakurai Masahiro Nakagawa Hajime Yamada Michiya Saito Koji Nakada Katsuhiko Iwakiri Takashi Joh Ken Haruma | 2017 | World Journal of Gastroenterology2017，23，2： | 3 |

| 20 | Walking-friendly built environments and objectively measured physical function in older adults显示文摘Background:Few studies have examined the associations between urban design attributes and older adults’physical function.Especially,it is not well known how built-environment attributes may influence physical function in Asian cities.The aim of this study was to examine associations between objectively measured environmental attributes of walkability and objectively assessed physical function in a sample of Japanese older adults.Methods:Cross-sectional data collected in 2013 from 314 older residents(aged 65-84 years)living in Japan were used.Physical function was estimated from objectively measured upper-and lower-body function,mobility,and balance by a trained research team member.A comprehensive list of built-environment attributes,including population density,availability of destinations,intersection density,and distance to the nearest public transport station,were objectively calculated.Walk Score as a composite measure of neighborhood walkability was also obtained.Results:Among men,higher population density,availability of destinations,and intersection density were significantly associated with better physical function performance(1-legged stance with eyes open).Higher Walk Score was also marginally associated with better physical function performance(1-legged stance with eyes open).None of the environmental attributes were associated with physical function in elderly women.Conclusion:Our findings indicate that environmental attributes of walkability are associated with the physical function of elderly men in the context of Asia.Walking-friendly neighborhoods can not only promote older adults’active behaviors but can also support their physical function. | Mohammad Javad Koohsari Gavin R.McCormack Tomoki Nakaya Ai Shibata Kaori Ishii Akitomo Yasunaga Yung Liao Koichiro Oka | 2020 | Journal of Sport and Health Science2020，9，6： | 3 |
