| 1 | Role of regulatory T cell in the pathogenesis of inflammatorybowel disease显示文摘Regulatory T(Treg) cells play key roles in various immune responses. For example, Treg cells contribute to the complex pathogenesis of inflammatory bowel disease(IBD), which includes Crohn's disease and ulcerative colitis during onset or development of that disease. Many animal models of IBD have been used to investigate factors such as pathogenic cytokines, pathogenic bacteria, and T-cell functions, including those of Treg cells. In addition, analyses of patients with IBD facilitate our understanding of the precise mechanism of IBD. This review article focuses on the role of Treg cells and outlines the pathogenesis and therapeutic strategies of IBD based on previous reports. | akiko yamada rieko arakaki masako saito takaaki tsunematsu yasusei kudo naozumi ishimaru | 2016 | World Journal of Gastroenterology2016，22，7： | 24 |
| 2 | Plexiform angiomyxoid myofi broblastic tumor of the stomach显示文摘Plexiform angiomyxoid myofibroblastic tumor of the stomach is a unique mesenchymal tumor that we first described in 2007.The tumor is very rare,and to date,only 18 cases confirmed by immunohistochemistry have been reported in the literature.The patients' ages ranged from 7 to 75 years(mean,43 years),and the male-to-female ratio was approximately 1:1.Representative clinical symptoms are ulceration,associated upper gastrointestinal bleeding(hematemesis),and anemia.The tumors are located at the antrum in all cases,and grossly,the tumor is whitish to brownish or reddish,and forms a lobulated submucosal or transmural mass.Microscopically,the tumor is characterized by a plexiform growth pattern,the proliferation of cytologically bland spindle cells,and a myxoid stroma that is rich in small vessels and positive for Alcian blue stain.Immunohistochemically,the tumor cells are positive for α-smooth muscle actin and negative for KIT and CD34.Differential diagnoses include gastrointestinal stromal tumor and other mesenchymal tumors of the gastrointestinal tract.Some authors proposed that this tumor should be designated as 'plexiform fibromyxoma',but this designation might cause confusion.The tumor is probably benign and thus far,neither recurrence nor metastasis has been reported. | Yoshihisa Takahashi Masako Suzuki Toshio Fukusato | 2010 | World Journal of Gastroenterology2010，16，23： | 12 |
| 3 | Potential effects of mesenchymal stem cell derived extracellular vesicles and exosomal miRNAs in neurological disorders显示文摘Mesenchymal stem cells are multipotent cells that possess anti-inflammatory,antiapoptotic and immunomodulatory properties.The effects of existing drugs for neurodegenerative disorders such as Alzheimer’s disease are limited,thus mesenchymal stem cell therapy has been anticipated as a means of ameliorating neuronal dysfunction.Since mesenchymal stem cells are known to scarcely differentiate into neuronal cells in damaged brain after transplantation,paracrine factors secreted from mesenchymal stem cells have been suggested to exert therapeutic effects.Extracellular vesicles and exosomes are small vesicles released from mesenchymal stem cells that contain various molecules,including proteins,mRNAs and microRNAs.In recent years,administration of exosomes/extracellular vesicles in models of neurological disorders has been shown to improve neuronal dysfunctions,via exosomal transfer into damaged cells.In addition,various microRNAs derived from mesenchymal stem cells that regulate various genes and reduce neuropathological changes in various neurological disorders have been identified.This review summarizes the effects of exosomes/extracellular vesicles and exosomal microRNAs derived from mesenchymal stem cells on models of stroke,subarachnoid and intracerebral hemorrhage,traumatic brain injury,and cognitive impairments,including Alzheimer’s disease. | Masako Nakano Mineko Fujimiya | 2021 | Neural Regeneration Research2021，16，12： | 9 |
| 4 | A prospective randomized trial of lafutidine vs rabeprazole on post-ESD gastric ulcers显示文摘AIM:To compare the effects of rabeprazole and lafutidine on post-endoscopic submucosal dissection(ESD) gastric ulcers.METHODS:Patients with gastric tumors indicated for ESD were prospectively studied.After ESD,all patients were treated with intravenous omeprazole for the first 3 d.Patients were then randomly assigned to oral lafutidine or rabeprazole.Ulcer size,ulcer size reduction rate,and ulcer stage were evaluated 4 wk later.Occurrence of complication was monitored throughout the 4-wk period.RESULTS:Sixty five patients were enrolled in the study,and 60 patients were subjected to the final analysis.In the lafutidine group(30 lesions in 29 patients),initial and 4-wk post-ESD ulcer sizes were 33.3 ± 9.2 and 10.5 ± 4.8 mm,respectively.In the rabeprazole group(34 lesions in 31 patients),the values were 34.7 ± 11.3 and 11.8 ± 6.7 mm,respectively.Ulcer size reduction rates in lafutidine and rabeprazole groups were 32.3% and 33.5%,respectively(P=0.974).Ulcer stage 4 wk post-ESD did not differ significantly between the two groups(P=0.868).Two cases in the rabeprazole group and no cases in the lafutidine group developed ulcer bleeding during the oral dose period,although the difference of bleeding rate between the two groups was not statistically significant(P=0.157).CONCLUSION:Lafutidine and rabeprazole have equivalent therapeutic effects on post-ESD gastric ulcers. | Tomohiko Richard Ohya Hiroki Endo Kei Kawagoe Tatsuro Yanagawa Katsuhiro Hanawa Ken Ohata Masako Asayama Kantaro Hisatomi Takuma Teratani Toshiaki Gunji Hajime Sato Nobuyuki Matsuhashi | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，1： | 7 |
| 5 | Skin toxicity predicts efficacy to sorafenib in patients with advanced hepatocellular carcinoma显示文摘AIM:To study the relationship between adverse events(AEs),efficacy,and nursing intervention for sorafenibtherapy in patients with hepatocellular carcinoma(HCC).METHODS:We enrolled 37 consecutive patients withadvanced HCC who received sorafenib therapy.Relationships among baseline characteristics as well as AEoccurrence and tumor response,overall survival(OS),and treatment duration were analyzed.The nursingintervention program consisted of education regardingself-monitoring and AEs management,and telephoneRESULTS:A total of 37 patients were enrolled in the study,comprising 30 males(81%) with a median age of 71 years.The disease control rate at 3 mo was 41%,and the median OS and treatment duration were 259 and 108 d,respectively.Nursing intervention was given to 24 patients(65%).Every patient exhibited some kinds of AEs,but no patients experienced G4 AEs.Frequently observed AEs > G2 included anorexia(57%),skin toxicity(57%),and fatigue(54%).Factors significantly associated with longer OS in multivariate analysis demonstrated that age ≤ 70 years,presence of > G2 skin toxicity,and absence of > G2 hypoalbuminemia.The disease control rate in patients with > G2 skin toxicity was 13/20(65%),which was significantly higher compared with that in patients with no or G1 skin toxicity.Multivariate analysis revealed that nursing intervention and > G2 skin toxicity were independent significant predictors for longer treatment duration.CONCLUSION:Skin toxicity was associated with favorable outcomes with sorafenib therapy for advanced HCC.Nursing intervention contributed to better adher-ence,which may improve the efficacy of sorafenib. | Masako Shomura Tatehiro Kagawa Koichi Shiraishi Shunji Hirose Yoshitaka Arase Tetsuya Mine Jun Koizumi | 2014 | World Journal of Hepatology2014，6，9： | 6 |
| 6 | Familial pancreatic cancer: Concept, management and issues显示文摘Familial pancreatic cancer (FPC) is broadly defined as two first-degree-relatives with pancreatic cancer (PC) and accounts for 4%-10% of PC. Several genetic syndromes, including Peutz-Jeghers syndrome, hereditary pancreatitis, hereditary breast-ovarian cancer syndrome(HBOC), Lynch syndrome, and familial adenomatous polyposis (FAP), also have increased risks of PC, but the narrowest definition of FPC excludes these known syndromes. When compared with other familial tumors, proven genetic alterations are limited to a small proportion (<20%) and the familial aggregation is usually modest. However, an ethnic deviation (Ashkenazi Jewish>Caucasian) and a younger onset are common also in FPC. In European countries, 'anticipation' is reported in FPC families, as with other hereditary syndromes; a trend toward younger age and worse prognosis is recognized in the late years. The resected pancreases of FPC kindred often show multiple pancreatic intraepithelial neoplasia (Pan IN) foci, with various K-ras mutations, similar to colorectal polyposis seen in the FAP patients. As with HBOC patients, a patient who is a BRCA mutation carrier with unresectable pancreatic cancer (accounting for 0%-19% of FPC patients) demonstrated better outcome following platinum and Poly (ADP-ribose) polymerase inhibitor treatment. Western countries have established FPC registries since the 1990 s and several surveillance projects for highrisk individuals are now ongoing to detect early PCs. Improvement in lifestyle habits, including non-smoking, is recommended for individuals at risk. In Japan, the FPC study group was initiated in 2013 and the Japanese FPC registry was established in 2014 by the Japan Pancreas Society. | Hiroyuki Matsubayashi Kyoichi Takaori Chigusa Morizane Hiroyuki Maguchi Masamichi Mizuma Hideaki Takahashi Keita Wada Hiroko Hosoi Shinichi Yachida Masami Suzuki Risa Usui Toru Furukawa Junji Furuse Takamitsu Sato Makoto Ueno Yoshimi Kiyozumi Susumu Hijioka Nobumasa Mizuno Takeshi Terashima Masaki Mizumoto Yuzo Kodama Masako Torishima Takahisa Kawaguchi Reiko Ashida Masayuki Kitano Keiji Hanada Masayuki Furukawa Ken Kawabe Yoshiyuki Majima Toru Shimosegawa | 2017 | World Journal of Gastroenterology2017，23，6： | 5 |
| 7 | OsIDD2, a zinc finger and INDETERMINATE DOMAIN protein, regulates secondary cell wall formation显示文摘Previously, we found 123 transcription factors(TFs) as candidate regulators of secondary cell wall(SCW)formation in rice by using phylogenetic and co-expression network analyses. Among them, we examined in this work the role of OsIDD_2, a zinc finger and indeterminate domain(IDD) family TF. Its overexpressors showed dwarfism, fragile leaves, and decreased lignin content, which are typical phenotypes of plants defective in SCW formation, whereas its knockout plants showed slightly increased lignin content.The RNA-seq and quantitative reverse transcription polymerase chain reaction analyses confirmed that some lignin biosynthetic genes were downregulated in the OsIDD_2-overexpressing plants, and revealed the same case for other genes involved in cellulose synthesis and sucrose metabolism. The transient expression assay using rice protoplasts revealed that OsIDD_2 negatively regulates the transcription of genes involved in lignin biosynthesis, cinnamyl alcohol dehydrogenase 2 and 3(CAD_2 and 3), and sucrose metabolism, sucrose synthase 5(SUS_5), whereas an Alpha Screen assay, which can detect the interaction between TFs and their target DNA sequences, directly confirmed the interaction between OsIDD_2 and the target sequences located in the promoter regions of CAD_2 and CAD_3. Based on these observations, we conclude that OsIDD_2 is negatively involved in SCW formation and other biological events by downregulating its target genes. | Peng Huang Hideki Yoshida Kenji Yano Shunsuke Kinoshita Kyosuke Kawai Eriko Koketsu Masako Hattori Sayaka Takehara Ji Huang Ko Hirano Reynante Lacsamana Ordonio Makoto Matsuoka Miyako Ueguchi-Tanaka | 2018 | Journal of Integrative Plant Biology2018，60，2： | 3 |
| 8 | Preparation,characterization and biological properties of a novel bone block composed of platelet rich fibrin and a deproteinized bovine bone mineral显示文摘Alveolar bone defects caused by tooth loss often lead to challenges in implant dentistry,with a need for development of optimal bone biomaterials to predictably rebuild these tissues.To address this problem,we fabricated a novel bone block using platelet-rich fibrin(PRF)and Deproteinized Bovine Bone Mineral(DBBM),and characterized their mechanical and biological properties.The bone block was prepared by mixing DBBM,Liquid-PRF,and Solid-PRF fragments in various combinations as follows:(1)BLOCK-1 made with Solid-PRF fragments+DBBM,(2)BLOCK-2 made with Liquid-PRF+DBBM,(3)BLOCK-3 made with Solid-PRF fragments+Liquid-PRF+DBBM.The time for solidification and the degradation properties were subsequently recorded.Scanning electron microscopy(SEM)and tensile tests were carried out to investigate the microstructure and mechanical properties of each block.The bioactivity of the three groups towards osteoblast differentiation was also evaluated by culturing cells with the conditioned medium from each of the three groups including cell proliferation assay,cell migration assay,alkaline phosphatase(ALP)staining,and alizarin red staining(ARS),as well as by real-time PCR for genes encoding runt-related transcription factor 2(RUNX2),ALP,collagen type I alphal(COLIv41)and osteocalcin(OCN).BLOCK-3 made with Solid-PRF fragments+Liquid-PRF+DBBM had by far the fastest solidification period(over a 10-fold increase)as well as the most resistance to degradation.SEM and tensile tests also revealed that the mechanical properties of BLOCK-3 were superior in strength when compared to all other groups and further induced the highest osteoblast migration and osteogenic differentiation confirmed by ALP,ARS and real-time PCR.PRF bone blocks made through the combination of Solid-PRF fragments+Liquid-PRF+DBBM had the greatest mechanical and biological properties when compared to either used alone.Future clinical studies are warranted to further support the clinical application of PRF bone blocks in bone regeneration procedures. | Mengge Feng Yulan Wang Yan Wei Xiaoxin Zhang Leyi Xiao Zijjian Gong Masako Fujioka-Kobayashi Anton Sculean Richard J Miron Scott Froum Yufeng Zhang | 2022 | Fundamental Research2022，2，2： | 3 |

| 11 | A successful treatment by hepatic arterial infusion therapy for advanced,unresectable biliary tract cancer显示文摘Biliary tract cancers(BTC)are relatively rare tumors, and the prognosis is extremely poor.There has been no standard chemotherapy for advanced BTC.However, recently,gemcitabine(GEM)have been used against BTC as the most active agent,and promising response rates and overall survival times with tolerable drug toxicities have been observed.In this article,two cases of advanced intrahepatic cholangiocarcinoma and unresectable metastatic gallbladder(GB)cancer are reported.They were treated with hepatic arterial infusion(HAI)chemotherapy using a combination of GEM and cisplatin,along with the systemic administration of GEM.As a consequence,multiple liver tumors,the GB cancer and metastatic lymph nodes regressed without severe drug toxicities,and favorable results(the overall survival times were 16 and 14 mo, respectively)were achieved.In conclusion,HAI therapy using GEM combined with cisplatin may be a useful and well-tolerated option for advanced BTC,especially in cases where multiple liver metastases are detected. | Masako Nishimura | 2010 | World Journal of Hepatology2010，2，5： | 3 |
| 12 | Characteristic pathological findings and effects of ecabet sodium in rat reflux esophagitis显示文摘AIM:To explore the pathological flndings in the entire esophagus in rats with reflux esophagitis, and the effects of ecabet sodium(ES).METHODS:A rat model of chronic acid reflux esophagitis was used.In the treatment group, ES was administered after surgery(n = 16).No drug was administered postoperatively to the esophagitis group(n = 9).Shamoperated rats were used as a control group(n = 5).Rats were sacriflced on day 7 after the operation.The epithelial thickness and leukocyte inflltration were examined in the upper, middle and lower areas of the esophagus.The survival rate, incidence of esophageal ulcer, and mean surface area and number of esophageal ulcers were determined in the esophagitis and ES groups.Esophageal histology was assessed in all three groups.RESULTS:Leukocyte infiltration in the esophagitis group was 26.3 ± 22.0 in the middle esophagus and 8.2 ± 4.9 in the upper esophagus, which was signiflcantly greater than that in the controls(1.3 ± 1.1 and 1.4 ± 1.0, respectively)(P < 0.05).The thickness of the epithelium in the esophagitis group was 210.8 ± 47.7 μm in the lower esophagus and 204.2 ± 60.1 μm in the middle esophagus, which was significantlygreater than that in the controls(26.0 ± 5.5 and 21.0 ± 6.5 μm, respectively)(P < 0.05).The mean number of ulcers per animal in the ES group in the entire esophagus was 5.4 ± 2.5, which was signiflcantly less than that in the esophagitis group(9.0 ± 3.5)(P < 0.05).The epithelial thickness in the ES group was 97.5 ± 32.2 μm in the lower esophagus, which was decreased compared with that in the esophagitis group(210.8 ± 47.7 μm)(P < 0.05).CONCLUSION:Mucosal inflammation extended to the upper esophagus close to the hypopharynx.Our study suggested that ES may have a useful defensive role in reflux esophagitis. | Daisuke Asaoka Akihito Nagahara Masako Oguro Yuko Izumi Akihiko Kurosawa Taro Osada Masato Kawabe Mariko Hojo Michiro Otaka Sumio Watanabe | 2009 | World Journal of Gastroenterology2009，15，28： | 2 |
| 13 | Human pluripotent stem cells:Towards therapeutic development for the treatment of lifestyle diseases显示文摘There are two types of human pluripotent stem cells: Embryonic stem cells(ESCs) and induced pluripotent stem cells(iPSCs),both of which launched themselves on clinical trials after having taken measures to overcome problems: Blocking rejections by immunosuppressants regarding ESCs and minimizing the risk of tumorigenicity by depleting exogenous gene components regarding iP SCs.It is generally assumed that clinical applications of human pluripotent stem cells should be limited to those cases where there are no alternative measures for treatments because of the risk in transplanting those cells to living bodies.Regarding lifestyle diseases,we have already several therapeutic options,and thus,development of human pluripotent stem cell-based therapeutics tends to be avoided.Nevertheless,human pluripotent stem cells can contribute to the development of new therapeutics in this field.As we will show,there is a case where only a short-term presence of human pluripotent stem-derived cells can exert long-term therapeutic effects even after they are rejected.In those cases,immunologically rejections of ESC-or allogenic iP SC-derived cells may produce beneficial outcomes by nullifying the risk of tumorigenesis without deterioration of therapeutic effects.Another utility of human pluripotent stem cells is the provision of an innovative tool for drug discovery that are otherwise unavailable.For example,clinical specimens of human classical brown adipocytes(BAs),which has been attracting a great deal of attention as a new target of drug discovery for the treatment of metabolic disorders,are unobtainable from living individuals due to scarcity,fragility and ethical problems.However,BA can easily be produced from human pluripotent stem cells.In this review,we will contemplate potential contribution of human pluripotent stem cells to therapeutic development for lifestyle diseases. | Miwako Nishio Masako Nakahara Akira Yuo Kumiko Saeki | 2016 | World Journal of Stem Cells2016，8，2： | 2 |
