| 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 |

| 4 | 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 |
| 5 | Effects of climate change on potential habitats of the cold temperate coniferous forest in Yunnan province, southwestern China显示文摘We built a classification tree(CT) model to estimate climatic factors controlling the cold temperate coniferous forest(CTCF) distributions in Yunnan province and to predict its potential habitats under the current and future climates, using seven climate change scenarios, projected over the years of 2070-2099. The accurate CT model on CTCFs showed that minimum temperature of coldest month(TMW) was the overwhelmingly potent factor among the six climate variables. The areas of TMW<-4.05 were suitable habitats of CTCF, and the areas of -1.35 < TMW were non-habitats, where temperate conifer and broad-leaved mixed forests(TCBLFs) were distribute in lower elevation, bordering on the CTCF. Dominant species of Abies, Picea, and Larix in the CTCFs, are more tolerant to winter coldness than Tsuga and broad-leaved trees including deciduous broad-leaved Acer and Betula, evergreen broadleaved Cyclobalanopsis and Lithocarpus in TCBLFs. Winter coldness may actually limit the cool-side distributions of TCBLFs in the areas between -1.35°C and -4.05°C, and the warm-side distributions of CTCFs may be controlled by competition to the species of TCBLFs. Under future climate scenarios, the vulnerable area, where current potential(suitable + marginal) habitats(80,749 km^2) shift to nonhabitats, was predicted to decrease to 55.91%(45,053 km^2) of the current area. Inferring from the current vegetation distribution pattern, TCBLFs will replace declining CTCFs. Vulnerable areas predicted by models are important in determining priority of ecosystem conservation. | LIWang-jun PENG Ming-chun Motoki HIGA Nobuyuki TANAKA Tetsuya MATSUI Cindy Q.

| 6 | Clues to the signals for chloroplast photorelocation from the lifetimes of accumulation and avoidance responses显示文摘Chloroplast photo-relocation movement is crucial for plant survival; however, the mechanism of this phenomenon is still poorly understood. Especially, the signal that goes from photoreceptor to chloroplast is unknown, although the photoreceptors(phototropin 1 and 2) have been identified and an actin structure(chloroplast actin filaments) has been characterized that is specific for chloroplast movement. Here,in gametophytes of the fern Adiantum capillus-veneris,gametophores of the moss Physcomiterella patens, and leaves of the seed plant Arabidopsis thaliana, we sought to characterize the signaling system by measuring the lifetime of the induced response. Chloroplast movements were induced by microbeam irradiation with high-intensity blue light and recorded. The lifetime of the avoidance state was measured as a lag time between switching off the beam and the loss of avoidance behavior, and that of the accumulation state was measured as the duration of accumulation behavior following the extinction of the beam. The lifetime for the avoidance response state is approximately 3–4 min and that for the accumulation response is 19–28 min. These data suggest that the two responses are based on distinct signals. | Takeshi Higa Masamitsu Wada | 2015 | Journal of Integrative Plant Biology2015，57，1： | 4 |
| 7 | Current status and future perspectives of radiomics in hepatocellular carcinoma显示文摘Given the frequent co-existence of an aggressive tumor and underlying chronic liver disease,the management of hepatocellular carcinoma(HCC)patients requires experienced multidisciplinary team discussion.Moreover,imaging plays a key role in the diagnosis,staging,restaging,and surveillance of HCC.Currently,imaging assessment of HCC entails the assessment of qualitative characteristics which are prone to inter-reader variability.Radiomics is an emerging field that extracts high-dimensional mineable quantitative features that cannot be assessed visually with the naked eye from medical imaging.The main potential applications of radiomic models in HCC are to predict histology,response to treatment,genetic signature,recurrence,and survival.Despite the encouraging results to date,there are challenges and limitations that need to be overcome before radiomics implementation in clinical practice.The purpose of this article is to review the main concepts and challenges pertaining to radiomics,and to review recent studies and potential applications of radiomics in HCC. | Joao Miranda Natally Horvat Gilton Marques Fonseca Jose de Arimateia Batista Araujo-Filho Maria ClaraFernandes Charlotte Charbel Jayasree Chakraborty Fabricio Ferreira Coelho Cesar Higa Nomura Paulo Herman | 2023 | World Journal of Gastroenterology2023，29，1： | 3 |
