| 3 | Helicobacter pylori-infected animal models are extremely suitable for the investigation of gastric carcinogenesis显示文摘Although various animal models have been developed to clarify gastric carcinogenesis, apparent mechanism of gastric cancer was not clarified in recent years. Since the recognition of the pathogenicity of Helicobacter pylori (Hpylori), several animal models with Hpylori infection have been developed to confirm the association between Hpylori and gastric cancer. Nonhuman primate and rodent models were suitable for this study. Japanese monkey model revealed atrophic gastritis and p53mutation after long-term infection of Hpylori. Mongolian gerbil model showed the development of gastric carcinoma with H pylori infection alone, as well as with combination of chemical carcinogens, such as N-methylN-nitrosourea and N-methyl-N-nitro-N'-nitrosoguanidine.The histopathological changes of these animal models after Hpylori inoculation are closely similar to those in human beings with Hpylori infection. Eradication therapy attenuated the development of gastric cancer in Hpyloriinfected Mongolian gerbil. Although several features of animal models differ from those seen in human beings,these experimental models provide a starting point for further studies to clarify the mechanism of gastric carcinogenesis as a result of Hpylori infection and assist the planning of eradication therapy to prevent gastric carcinoma. | Masaaki Kodama Kazunari Murakami Ryugo Sato Tadayoshi Okimoto Akira Nishizono Toshio Fujioka | 2005 | World Journal of Gastroenterology2005，11，45： | 19 |
| 4 | Expression of mutant type-p53 products in H pylori-associated chronic gastritis显示文摘AIM:To investigate the mutation of p 53 immuno-histochemically in non-tumorous gastric mucosa with H pylori infection before and after H pylori eradication therapy.METHODS:53 subjects(36 male,17 female,mean age ± SEM,57.1 ± 12.1)undergoing endoscopic examination were included in this study.42 of 53 patients were H pylori-positive,and 11 were H pylori-negative.All H pylori-positive patients had successful eradication therapy.Biopsy specimens were taken from five points of the stomach,as recommended by the updated Sydney system.Immunohistochemical studies were performed by using primary antibodies against p53(DO-7 and PAb240).RESULTS:p53(DO-7 and PAb240)immunoreactivity was shown in the neck region of the gastric pits,however,quite a few cells were found to be immunopositive for p 53(PAb240)in the H pylori-infected gastric mucosa.The proportion of patients immunopositive for p 53(PAb240)was significantly reduced 6 mo after eradication [28/42(66.7%)to 6/42(14.3%)](P < 0.05),while the biopsies taken from H pylori-negative patients showed no immunoreactivity for p53(PAb240).p53(PAb240)-positive patients were divided into two groups by the number of positive cells detected:one with more than six positive cells per 10 gastric pits(group A,n = 12),and the other with less than five positive cells per 10 gastric pits(group B,n = 30).Atrophy scores in group A were significant higher than those in group B at the greater curvature of the antrum(group A:2.00 ± 0.14 vs group B:1.40 ± 0.15,P = 0.012),the lesser curvature of the corpus(group A:2.00 ± 0.21 vs group B:1.07 ± 0.23,P = 0.017),and the greater curvature of the corpus(group A:1.20 ± 0.30vs group B:0.47 ± 0.21,P = 0.031).Group A showed significant higher intestinal metaplasia scores than group B only at the lesser curvature of the antrum(group A:2.10 ± 0.41 vs group B:1.12 ± 0.29,P = 0.035).CONCLUSION:H pylori-associated chronic gastritis expressed the mutant-type p53,which was significantly associated with more severe atrophic and metaplastic changes.H pylori eradication led to a significant reduction in the expression of the mutant-type p53.It is considered that H pylori-infected chronic gastritis is associated with a genetic instability that leads to gastric carcinogenesis,and H pylori eradication may prevent gastric cancer. | Masaaki Kodama Kazunari Murakami Tadayoshi Okimoto Ryugo Sato Koichiro Watanabe Toshio Fujioka | 2007 | World Journal of Gastroenterology2007，13，10： | 13 |
| 5 | Aspirin-induced small bowel injuries and the preventive effect of rebamipide显示文摘AIM:To evaluate the influence of taking low-dose aspirin for 4 wk on small intestinal complications and to examine the preventive effect of rebamipide.METHODS:This study was conducted as a single-center,randomized,double-blind,cross-over,placebo-controlled study.Eleven healthy male subjects were enrolled.Each subject underwent video capsule endos-copy after 1 and 4 wk of taking aspirin and omepra-zole,along with either rebamipide or placebo therapy.The primary endpoint was to evaluate small bowel damage in healthy subjects before and after taking low-dose aspirin for 4 wk.RESULTS:The number of subjects with mucosal breaks(defined as multiple erosions and/or ulcers)were 1 at 1 wk and 1 at 4 wk on the jejunum,and 6 at 1 wk(P = 0.0061)and 7 at 4 wk on the ileum(P =0.0019).Rebamipide significantly prevented mucosal breaks on the ileum compared with the placebo group(P = 0.0173 at 1 wk and P = 0.0266 at 4 wk).CONCLUSION:Longer-term,low-dose aspirin adminis-tration induced damage in the small bowel.Rebamipide prevented this damage,and may be a candidate drug for treating aspirin-induced small bowel complications. | Kazuhiro Mizukami Kazunari Murakami Takashi Abe Kunimitsu Inoue Masahiro Uchida Tadayoshi Okimoto Masaaki Kodama Toshio Fujioka | 2011 | World Journal of Gastroenterology2011，17，46： | 8 |
| 6 | Extremely high prevalence of Helicobacter pylori infection in Bhutan显示文摘AIM: To revealed the prevalence of Helicobacter pylori (H. pylori ) infection in the Bhutanese population. METHODS: We recruited a total of 372 volunteers (214 females and 158 males; mean age of 39.6 ± 14.9 years) from three Bhutanese cities (Thimphu, Punaka, and Wangdue). The status of H. pylori infection was determined based on five different tests: the rapid urease test (CLO test), culture, histology, immunohistochemistry (IHC), and serum anti H. pylori -antibody. RESULTS: The serological test showed a significantly higher positive rate compared with the CLO test, culture, histology and IHC (P < 0.001, P < 0.001, P=0.01, and P=0.01, respectively). When the subjects were considered to be H. pylori positive in the case of at least one test showing a positive result, the overall prevalence of H. pylori infection in Bhutan was 73.4%. The prevalence of H. pylori infection significantly decreased with age (P < 0.01). The prevalence of H. pylori infection was lower in Thimphu than in Punakha and Wangdue (P=0.001 and 0.06, respectively). The prevalence of H. pylori infection was significantly higher in patients with peptic ulcers than in those with gastritis (91.4% vs 71.3%, P=0.003). CONCLUSION: The high incidence of gastric cancer in Bhutan may be attributed to the high prevalence of H. pylori infection. | Ratha-korn Vilaichone Varocha Mahachai Seiji Shiota Tomohisa Uchida Thawee Ratanachu-ek Lotay Tshering Nguyen Lam Tung Toshio Fujioka Masatsugu Moriyama Yoshio Yamaoka | 2013 | World Journal of Gastroenterology2013，19，18： | 8 |
| 7 | Influence of proton pump inhibitor treatment on Helicobacter pylori stool antigen test显示文摘AIM: To investigate the effects of proton pump inhibitor (PPI) treatment on stool antigen test using the TestMate pylori enzyme immunoassay. METHODS: This study assessed 28 patients [16 men and 12 women; mean age (63.1 ± 5.9) years; range, 25-84 years] who underwent stool antigen test and urea breath test (UBT) before and after PPI administration. RESULTS: Using the UBT as the standard, the sensitivity, specif icity and agreement of the stool antigen test in all 28 patients were 95.2%, 71.4%, and 89.3%, respectively, before PPI administration, and 88.9%, 90.9%, and 89.3%, respectively, after PPI treatment. Mean UBT values were 23.98% ± 5.33% before and 16.19% ± 4.75% after PPI treatment and, in 15 patients treated for ≥ 4 wk, were signif icantly lower after than before 4 wk of PPI treatment (12.58% ± 4.49% vs 24.53% ± 8.53%, P = 0.048). The mean optical density (A450/630) ratios on the stool antigen test were 1.16 ± 0.20 before and 1.17 ± 0.24 after PPI treatment (P = 0.989), and were 1.02 ± 0.26 and 0.69 ± 0.28, respectively, in the group treated for > 4 wk (P = 0.099). | Masaaki Kodama Kazunari Murakami Tadayoshi Okimoto Yoshihiro Fukuda Tadashi Shimoyama Masumi Okuda Chieko Kato Intetsu Kobayashi Toshio Fujioka | 2012 | World Journal of Gastroenterology2012，18，1： | 7 |

| 9 | Antibiotics resistance rate of Helicobacter pylori in Bhutan显示文摘AIM:To survey the antibiotic resistance pattern of Helicobacter pylori(H.pylori)strains isolated from Bhutanese population.METHODS:We isolated 111 H.pylori strains from the gastric mucosa of H.pylori-infected patients in Bhutan in 2010.The Epsilometer test was used to determine the minimum inhibitory concentrations(MICs)of amoxicillin(AMX),clarithromycin(CLR),metronidazole(MNZ),levofloxacin(LVX),ciprofloxacin(CIP),and tetracycline(TET).RESULTS:Nineteen of the isolated H.pylori strains were susceptible to all antibiotics tested.The isolated strains showed the highest rate of antibiotic resistance to MNZ(92/111,82.9%).Among the 92 MNZresistant strains,74 strains(80.4%)showed high-level resistance(MIC≥256 g/mL).Three strains were resistance to LVX(2.7%).These strains were also resistance to CIP.None of the strains showed resistance to CLR,AMX and TET.CONCLUSION:CLR-based triple therapy is a more effective treatment approach over MNZ-based triple therapy for H.pylori infection in Bhutan. | Ratha-korn Vilaichone Yoshio Yamaoka Seiji Shiota Thawee Ratanachu-ek Lotay Tshering Tomohisa Uchida Toshio Fujioka Varocha Mahachai | 2013 | World Journal of Gastroenterology2013，19，33： | 6 |
| 10 | A novel animal model for in vivo study of liver cancer metastasis显示文摘AIM:To establish an animal model with human hepatocyte-repopulated liver for the study of liver cancer metastasis.METHODS:Cell transplantation into mouse livers was conducted using alpha-fetoprotein(AFP)-producing hu-man gastric cancer cells(h-GCCs) and h-hepatocytes as donor cells in a transgenic mouse line expressing urokinase-type plasminogen activator(uPA) driven by the albumin enhancer/promoter crossed with a severe combined immunodeficient(SCID) mouse line(uPA/SCID mice).Host mice were divided into two groups(A and B).Group A mice were transplanted with h-GCCs alone,and group B mice were transplanted with h-GCCs and h-hepatocytes together.The replacement index(RI),which is the ratio of transplanted h-GCCs and h-hepatocytes that occupy the examined area of a histological section,was estimated by measuring h-AFP and h-albumin concentrations in sera,respectively,as well as by immunohistochemical analyses of h-AFP and human cytokeratin 18 in histological sections.RESULTS:The h-GCCs successfully engrafted,repopulated,and colonized the livers of mice in group A(RI = 22.0% ± 2.6%).These mice had moderately differentiated adenocarcinomatous lesions with disrupted glandular structures,which is a characteristics feature of gastric cancers.The serum h-AFP level reached 211.0 ± 142.2 g/mL(range,7.1-324.2 g/mL).In group B mice,the h-GCCs and h-hepatocytes independently engrafted,repopulated the host liver,and developed colonies(RI = 12.0% ± 6.8% and 66.0% ± 12.3%,respectively).h-GCC colonies also showed typical adenocarcinomatous glandular structures around the h-hepatocyte-colonies.These mice survived for the full 56 day-study and did not exhibit any metastasis of h-GCCs in the extrahepatic regions during the observational period.The mice with an h-hepatocyte-repopulated liver possessed metastasized h-GCCs and therefore could be a useful humanized liver animal model for studying liver cancer metastasis in vivo.CONCLUSION:A novel animal model of human liver cancer metastasis was established using the uPA/SCID mouse line.This model could be useful for in vivo testing of anti-cancer drugs and for studying the mechanisms of human liver cancer metastasis. | Shinsuke Fujiwara Hikaru Fujioka Chise Tateno Ken Taniguchi Masahiro Ito Hiroshi Ohishi Rie Utoh Hiromi Ishibashi Takashi Kanematsu Katsutoshi Yoshizato | 2012 | World Journal of Gastroenterology2012，18，29： | 6 |
| 11 | Comparison between bioartificial and artificial liver for the treatment of acute liver failure in pigs显示文摘AIM: To characterize and evaluate the therapeuti efficacy of bioartificial liver (BAL) as compared to tha of continuous hemodiafiltration (CHDF) with plasma exchange (PE), which is the current standard therapy fo fulminant hepatic failure (FHF) in Japan. METHODS: Pigs with hepatic devascularization were divided into three groups: (1) a non-treatment group (NT; n = 4); (2) a BAL treatment group (BAL; n = 4) (3) a PE + CHDF treatment group using 1.5 L of norma porcine plasma with CHDF (PE + CHDF, n = 4). Our BA system consisted of a hollow fiber module with 0.2 μm pores and 1 x 1010 of microcarrier-attached hepatocyte inoculated into the extra-fiber space. Each treatment wa initiated 4 h after hepatic devascularization. RESULTS: The pigs in the BAL and the PE + CHD groups survived longer than those in the NT group. The elimination capacity of blood ammonia by both BAL and PE + CHDF was significantly higher than that in NT Aromatic amino acids (AAA) were selectively eliminated by BAL, whereas both AAA and branched chain amino acids, which are beneficial for life, were eliminated by PE + CHDF. Electrolytes maintenance and acid-base balance were better in the CPE + CHDF group than that in the BAL group. CONCLUSION: Our results suggest that PE + CHDF eliminate all factors regardless of benefits, wherea BAL selectively metabolizes toxic factors such as AAA However since PE + CHDF maintain electrolytes and acid-base balance, a combination therapy of BAL plu CPE + CHDF might be more effective for FHF. | Yasushi Kawazoe Susumu Eguchi Nozomu Sugiyama Yukio Kamohara Hikaru Fujioka Takashi Kanematsu | 2006 | World Journal of Gastroenterology2006，12，46： | 5 |

| 16 | Tumor characteristics of ductal carcinoma in situ of breast visualized on [F-18] fluorodeoxyglucose-positron emission tomography/computed tomography: Results from a retrospective study显示文摘AIM To clarify clinicopathological features of ductal carcinoma in situ(DCIS) visualized on [F-18] fluorodeoxyglucosepositron emission tomography/computed tomography(FDG-PET/CT).METHODS This study retrospectively reviewed 52 consecutive tumors in 50 patients with pathologically proven pure DCIS who underwent [F-18] FDG-PET/CT before surgery. [F-18] FDG-PET/CT was performed after biopsy in all patients. The mean interval from biopsy to [F-18] FDGPET/CT was 29.2 d. [F-18] FDG uptake by visual analysis and maximum standardized uptake value(SUVmax) was compared with clinicopathological characteristics.RESULTS[F-18] FDG uptake was visualized in 28 lesions(53.8%) and the mean and standard deviation of SUVmax was 1.63 and 0.90. On univariate analysis, visual analysis and the SUVmax were associated with symptomatic presentation(P = 0.012 and 0.002, respectively), palpability(P = 0.030 and 0.024, respectively), use of core-needle biopsy(CNB)(P = 0.023 and 0.012, respectively), ultrasound-guided biopsy(P = 0.040 and 0.006, respectively), enhancing lesion ≥ 20 mm on magnetic resonance imaging(MRI)(P = 0.001 and 0.010, respectively), tumor size ≥ 20 mm on histopathology(P = 0.002 and 0.008, respectively). However, [F-18] FDG uptake parameters were not significantly associated with age, presence of calcification on mammography, mass formation on MRI, presence of comedo necrosis, hormone status(estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2), and nuclear grade. The factors significantly associated with visual analysis and SUVmax were symptomatic presentation(P = 0.019 and 0.001, respectively), use of CNB(P = 0.001 and 0.031, respectively), and enhancing lesion ≥ 20 mm on MRI(P = 0.001 and 0.049, respectively) on multivariate analysis.CONCLUSION Although DCIS of breast is generally non-avid tumor, symptomatic and large tumors(≥ 20 mm) tend to be visualized on [F-18] FDG-PET/CT. | Tomoyuki Fujioka Kazunori Kubota Akira Toriihara Youichi Machida Kaori Okazawa Tsuyoshi Nakagawa Yukihisa Saida Ukihide Tateishi | 2016 | World Journal of Radiology2016，8，8： | 2 |
