| 1 | Fucoidan enhances intestinal barrier function by upregulating the expression of claudin-1显示文摘AIM:To evaluate the protective effects of fucoidan on oxidative stress-induced barrier disruption in human intestinal epithelial cells.METHODS:In Caco-2 cell monolayer models,the disruption of barrier function by oxidative stress is mediated by H2O2.The integrity of polarized Caco-2 cell monolayers was determined by measuring the transepithelial resistance(TER)and permeability was estimated by measuring the paracellular transport of FITC-labeled4-kDa dextran(FD4).The protective effects of fucoidan on epithelial barrier functions on polarized Caco-2 cell monolayers were evaluated by TER and FD4 flux.The expression of tight junction(TJ)proteins was assessed using reverse-transcription polymerase chain reaction(RT-PCR)and immunofluorescence staining.RESULTS:Without H2O2treatment,fucoidan significantly increased the TER compared to control(P<0.05),indicating a direct enhancement of intestinal epithelial barrier function.Next,H2O2disrupted the epithelial barrier function in a time-dependent manner.Fucoidan prevented the H2O2-induced destruction in a dosedependent manner.Fucoidan significantly decreased H2O2-induced FD4 flux(P<0.01),indicating the prevention of disruption in paracellular permeability.RTPCR showed that Caco-2 cells endogenously expressed claudin-1 and-2,and occludin and that H2O2reduced the mRNA expression of these TJ proteins.Treatment with fucoidan attenuated the reduction in the expressions of claudin-1 and claudin-2 but not occludin.Immunofluorescence staining revealed that the expression of claudin-1 was intact and high on the cell surface.H2O2disrupted the integrity of claudin-1.Treatment with fucoidan dramatically attenuated the expression of claudin-1.CONCLUSION:Fucoidan enhanced intestinal epithelial barrier function by upregulating the expression of claudin-1.Thus,fucoidan may be an appropriate therapy for the treatment of inflammatory bowel diseases. | Atsushi Iraha Hiroshi Chinen Akira Hokama Takumi Yonashiro Tetsu Kinjo Kazuto Kishimoto Manabu Nakamoto Tetsuo Hirata Nagisa Kinjo Futoshi Higa Masao Tateyama Fukunori Kinjo Jiro Fujita | 2013 | World Journal of Gastroenterology2013，19，33： | 15 |
| 2 | Diagnosis of intestinal tuberculosis using a monoclonal antibody to Mycobacterium tuberculosis显示文摘AIM:To investigate the utility of immunohistochemical(IHC) staining with an antibody to Mycobacterium tuberculosis(M.tuberculosis) for the diagnosis of intestinal tuberculosis(TB).METHODS:We retrospectively identified 10 patients(4 males and 6 females;mean age = 65.1 ± 13.6 years) with intestinal TB.Clinical characteristics,including age,gender,underlying disease,and symptoms were obtained.Chest radiograph and laboratory tests,including sputum Ziehl-Neelsen(ZN) staining,M.tuberculosis culture,and sputum polymerase chain reaction(PCR) for tubercle bacilli DNA,as well as Tuberculin skin test(TST) and QuantiFERON-TB gold test(QFT),were examined.Colonoscopic records recorded on the basis of Sato's classification were also reviewed,in addition to data from intestinal biopsies examined for histopathological findings,including hematoxylin and eosin staining,and ZN staining,as well as M.tuberculosis culture,and PCR for tubercle bacilli DNA.For the present study,archived formalin-fixed paraffin-embedded(FFPE) intestinal tissue samples were immunohistochemically stained using a commercially available species-specific monoclonal antibody to the 38-kDa antigen of the M.tuberculosis complex.These sections were also stained with the pan-macrophage marker CD68 antibody.RESULTS:From the clinical data,we found that no patients were immunocompromised,and that the main symptoms were diarrhea and weight loss.Three patients displayed active pulmonary TB,six patients(60%) had a positive TST,and 4 patients(40%) had a positive QFT.Colonoscopic findings revealed that all patients had type 1 findings(linear ulcers in a circumferential arrangement or linear ulcers arranged circumferentially with mucosa showing multiple nodules),all of which were located in the right hemicolon and/or terminal ileum.Seven patients(70%) had concomitant healed lesions in the ileocecal area.No acid-fast bacilli were detected with ZN staining of the intestinal tissue samples,and both M.tuberculosis culture and PCR for tubercle bacilli DNA were negative in all samples.The histopathological data revealed that tuberculous granulomas were present in 4 cases(40%).IHC staining in archived FFPE samples with anti-M.tuberculosis monoclonal antibody revealed positive findings in 4 patients(40%);the same patients in which granulomas were detected by hematoxylin and eosin staining.M.tuberculosis antigens were found to be mostly intracellular,granular in pattern,and primarily located in the CD68 + macrophages of the granulomas.CONCLUSION:IHC staining with a monoclonal antibody to M.tuberculosis may be an efficient and simple diagnostic tool in addition to classic examination methods for the diagnosis of intestinal TB. | Yasushi Ihama Akira Hokama Kenji Hibiya Kazuto Kishimoto Manabu Nakamoto Tetsuo Hirata Nagisa Kinjo Haley L Cash Futoshi Higa Masao Tateyama Fukunori Kinjo Jiro Fujita | 2012 | World Journal of Gastroenterology2012，18，47： | 12 |
| 3 | Endoscopic and radiographic features of gastrointestinal involvement in vasculitis显示文摘Vasculitis is an inflammation of vessel walls,followed by alteration of the blood flow and damage to the dependent organ.Vasculitis can cause local or diffuse pathologic changes in the gastrointestinal (GI) tract.The variety of GI lesions includes ulcer,submucosal edema,hemorrhage,paralytic ileus,mesenteric ischemia,bowel obstruction,and life-threatening perforation.The endoscopic and radiographic features of GI involvement in vasculitisare reviewed with the emphasis on small-vessel vasculitis by presenting our typicalcases,including Churg-Strauss syndrome,HenochSch nlein purpura,systemic lupus erythematosus,and Beh et's disease.Important endoscopic features are ischemic enterocolitis and ulcer.Characteristic computed tomographic findings include bowel wall thickening with the target sign and engorgement of mesenteric vessels with comb sign.Knowledge of endoscopic and radiographic GI manifestations can help make an early diagnosis and establish treatment strategy. | Akira Hokama Kazuto Kishimoto Yasushi Ihama Chiharu Kobashigawa Manabu Nakamoto Tetsuo Hirata Nagisa Kinjo Futoshi Higa Masao Tateyama Fukunori Kinjo Kunitoshi Iseki Seiya Kato Jiro Fujita | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，3： | 9 |
| 4 | Pegylated interferon plus ribavirin for genotype Ib chronic hepatitis C in Japan显示文摘AIM:To evaluate the efficacy of pegylated interferon α-2b(peg-IFNα-2b) plus ribavirin(RBV) therapy in Japanese patients with chronic hepatitis C(CHC) genotype Ib and a high viral load.METHODS:One hundred and twenty CHC patients(58.3% male) who received peg-IFNα-2b plus RBV therapy for 48 wk were enrolled.Sustained virological response(SVR) and clinical parameters were evaluated.RESULTS:One hundred(83.3%) of 120 patients completed 48 wk of treatment.53 patients(44.3%) achieved SVR.Early virological response(EVR) and end of treatment response(ETR) rates were 50% and 73.3%,respectively.The clinical parameters(SVR vs non-SVR) associated with SVR,ALT(108.4 IU/L vs 74.5 IU/L,P = 0.063),EVR(76.4% vs 16.4%,P < 0.0001),adherence to peg-IFN(≥ 80% of planned dose) at week 12(48.1% vs 13.6%,P = 0.00036),adherence to peg-IFN at week 48(54.7% vs 16.2%,P < 0.0001) and adherence to RBV at week 48(56.1% vs 32.1%,P = 0.0102) were determined using univariate analysis,and EVR and adherence to peg-IFN at week 48 were determined using multivariate analysis.In the older patient group(> 56 years),SVR in females was significantly lower than that in males(17% vs 50%,P = 0.0262).EVR and adherence to Peg-IFN were demonstrated to be the main factors associated with SVR.CONCLUSION:Peg-IFNα-2b plus RBV combination therapy demonstrated good tolerability in Japanese patients with CHC and resulted in a SVR rate of 44.3%.Treatment of elderly female patients is still challenging and maintenance of adherence to peg-IFNα-2b is important in improving the SVR rate. | Takayuki Kogure Yoshiyuki Ueno Koji Fukushima Futoshi Nagasaki Yasuteru Kondo Jun Inoue Yasunori Matsuda Eiji Kakazu Takeshi Yamamoto Hiroyoshi Onodera Yutaka Miyazaki Hiromasa Okamoto Takehiro Akahane Tomoo Kobayashi Yutaka Mano Takao Iwasaki Motoyasu Ishii Tooru Shimosegawa | 2008 | World Journal of Gastroenterology2008，14，47： | 7 |
| 5 | Fulminant hepatic failure in a case of autoimmune hepatitis in hepatitis C during peg-interferon-alpha 2b plus ribavirin treatment显示文摘A 27-year-old Caucasian female with hepatitis C virus (HCV) infection treated with interferon (IFN) who developed severe autoimmune hepatitis (AIH) is described. The infecting viral strain was of genotype Ib and the pre-treatment HCV viral load was at a high level. The patient was treated with pegylated IFN-alpha 2b and ribavirin,and her HCV-RNA became negative at wk 12,but after that she developed fulminant hepatic failure. The patient recovered after steroid pulse therapy consisting of methylprednisolone 1000 mg/d for three days which was administered twice. A needle liver biopsy revealed the typical pathological findings of AIH. | Takayuki Kogure Yoshiyuki Ueno Koji Fukushima Futoshi Nagasaki Jun Inoue Eiji Kakazu Yasunori Matsuda Osamu Kido Yu Nakagome Osamu Kimura Noriyuki Obara Yuta Wakui Takao Iwasaki Tooru Shimosegawa | 2007 | World Journal of Gastroenterology2007，13，32： | 5 |

| 7 | Clinical impacts of mesothelin expression in gastrointestinal carcinomas显示文摘Mesothelin,C-ERC/mesothelin is a 40-kD a cell surface glycoprotein that is normally present on normal mesothelial cells lining the pleura,peritoneum,and pericardium.Moreover,mesothelin has been shown to be overexpressed in several human cancers,including virtually all mesothelioma and pancreatic cancer approximately 70% of ovarian cancer and extra bile duc cancer,and 50% of lung adenocarcinomas and gastric cancer.The full-length human mesothelin gene encodes the primary product,a 71-k Da precursor protein.The71-kD a mesothelin precursor is cleaved into two products40-k Da C-terminal fragment that remains membranebound via glycosylphosphatidylinositol anchor,and a31-kD a N-terminal fragment,megakaryocyte potentiating factor,which is secreted into the blood.The biologica functions of mesothelin remain largely unknown However,results of recent studies have suggested tha the mesothelin may play a role of cell proliferation and migration.In pancreatic cancer,mesothelin expression was immunohistochemically observed in all cases,bu absent in normal pancreas and in chronic pancreatitis Furthermore,the expression of mesothelin was correlated with an poorer patient outcome in severa human cancers.The limited mesothelin expression in normal tissues and high expression in many cancers makes it an attractive candidate for cancer therapy.The present review discusses the expression and function o mesothelin in cancer cells and the utility of mesothelin as a target of cancer therapy. | Takahiro Einama Futoshi Kawamata Hirofumi Kamachi Hiroshi Nishihara Shigenori Homma Fumihiko Matsuzawa Tatsuzo Mizukami Yuji Konishi Munenori Tahara Toshiya Kamiyama Okio Hino Akinobu Taketomi Satoru Todo | 2016 | World Journal of Gastrointestinal Pathophysiology2016，7，2： | 4 |
| 8 | Effect of roselle calyx extract on in vitro viability and biofilm formation ability of oral pathogenic bacteria显示文摘Objective: To investigate the effect of the roselle calyx extract(RCE)(Hibiscus sabdariffa L.) on the in vitro viability and biofilm formation ability of oral pathogenic bacteria. Methods:RCE was prepared by soaking roselle calyx powder with ethyl alcohol for 24 h at room temperature. After centrifugation, the extract was lyophilized. Then, the extract was dissolved in phosphate-buffered saline, the p H was adjusted, and the extract was aseptically filtered. We used Streptococcus mutans, Streptococcus sanguinis, Lactobacillus casei, Actinomyces naeslundii, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis and Prevotella intermedia in this study. The antibacterial activity of the RCE was determined by treating the cells of these bacteria with the extract for 10 or 20 min at room temperature. The minimum inhibitory concentration(MIC) and minimum bactericidal concentration was determined using the micro dilution method, and the effect of the RCE on the ability to form biofilm was determined using a polystyrene micro plate assay. In addition, we used the WST-1 assay to determine the cytotoxicity of the RCE on HGF, Ca9-22 and KB cells. Results: The RCE had antibacterial activity against oral bacteria used in this study. In particular, most significant antibacterial activity was observed against Fusobacterium nucleatum, Prevotella intermedia and Porphyromonas gingivalis. The MIC and minimum bactericidal concentration were 7.2 mg/m L–28.8 mg/m L and 14.4 to >57.6 mg/m L. The RCE had an inhibitory effect on biofilm formation at the MIC and sub-MIC levels. In addition, the RCE had low cytotoxic effects on HGF, Ca9-22 and KB cells. Conclusions: Thus, our results indicate that the RCE may be used for preventing oral diseases. | Herastuti Sulistyani Mari Fujita Hiroshi Miyakawa Futoshi Nakazawa | 2016 | Asian Pacific Journal of Tropical Medicine2016，9，2： | 3 |
