| 1 | Association of Fusobacterium nucleatum with immunity andmolecular alterations in colorectal cancer显示文摘The human intestinal microbiome plays a major role in human health and diseases, including colorectal cancer. Colorectal carcinogenesis represents a heterogeneous process with a differing set of somatic molecular alterations, influenced by diet, environmental and microbial exposures, and host immunity. Fusobacterium species are part of the human oral and intestinal microbiota. Metagenomic analyses have shown an enrichment of Fusobacterium nucleatum(F. nucleatum) in colorectal carcinoma tissue. Using 511 colorectal carcinomas from Japanese patients, we assessed the presence of F. nucleatum. Our results showed that the frequency of F. nucleatum positivity in the Japanese colorectal cancer was 8.6%(44/511), which was lower than that in United States cohort studies(13%). Similar to the United States studies, F. nucleatum positivityin Japanese colorectal cancers was significantly associated with microsatellite instability(MSI)-high status. Regarding the immune response in colorectal cancer, high levels of infiltrating T-cell subsets(i.e., CD3+, CD8+, CD45RO+, and FOXP3+ cells) have been associated with better patient prognosis. There is also evidence to indicate that molecular features of colorectal cancer, especially MSI, influence T-cell-mediated adaptive immunity. Concerning the association between the gut microbiome and immunity, F. nucleatum has been shown to expand myeloid-derived immune cells, which inhibit T-cell proliferation and induce T-cell apoptosis in colorectal cancer. This finding indicates that F. nucleatum possesses immunosuppressive activities by inhibiting human T-cell responses. Certain micro RNAs are induced during the macrophage inflammatory response and have the ability to regulate host-cell responses to pathogens. Micro RNA-21 increases the levels of IL-10 and prostaglandin E2, which suppress antitumor T-cell-mediated adaptive immunity through the inhibition of the antigen-presenting capacities of dendritic cells and T-cell proliferation in colorectal cancer cells. Thus, emerging evidence may provide insights for strategies to target microbiota, immune cells and tumor molecular alterations for colorectal cancer prevention and treatment. Further investigation is needed to clarify the association of Fusobacterium with T-cells and micro RNA expressions in colorectal cancer. | Katsuhiko Nosho Yasutaka Sukawa Yasushi Adachi Miki Ito Kei Mitsuhashi Hiroyoshi Kurihara Shinichi Kanno Itaru Yamamoto Keisuke Ishigami Hisayoshi Igarashi Reo Maruyama Kohzoh Imai Hiroyuki Yamamoto Yasuhisa Shinomura | 2016 | World Journal of Gastroenterology2016，22，2： | 44 |
| 2 | Diagnosis and Treatment of Keloids and Hypertrophic Scars—Japan Scar Workshop Consensus Document 2018显示文摘There has been a long-standing need for guidelines on the diagnosis and treatment of keloids and hypertrophic scars that are based on an understanding of the pathomechanisms that underlie these skin fibrotic diseases.This is particularly true for clinicians who deal with Asian and African patients because these ethnicities are highly prone to these diseases.By contrast,Caucasians are less likely to develop keloids and hypertrophic scars,and if they do,the scars tend not to be severe.This ethnic disparity also means that countries vary in terms of their differential diagnostic algorithms.The lack of clear treatment guidelines also means that primary care physicians are currently applying a hotchpotch of treatments,with uneven outcomes.To overcome these issues,the Japan Scar Workshop(JSW)has created a tool that allows clinicians to objectively diagnose and distinguish between keloids,hypertrophic scars,and mature scars.This tool is called the JSW Scar Scale(JSS)and it involves scoring the risk factors of the individual patients and the affected areas.The tool is simple and easy to use.As a result,even physicians who are not accustomed to keloids and hypertrophic scars can easily diagnose them and judge their severity.The JSW has also established a committee that,in cooperation with outside experts in various fields,has prepared a Consensus Document on keloid and hypertrophic scar treatment guidelines.These guidelines are simple and will allow even inexperienced clinicians to choose the most appropriate treatment strategy.The Consensus Document is provided in this article.It describes(1)the diagnostic algorithm for pathological scars and how to differentiate them from clinically similar benign and malignant tumors,(2)the general treatment algorithms for keloids and hypertrophic scars at different medical facilities,(3)the rationale behind each treatment for keloids and hypertrophic scars,and(4)the body site-specific treatment protocols for these scars.We believe that this Consensus Document will be helpful for physicians from all over the world who treat keloids and hypertrophic scars. | Rei Ogawa Sadanori Akita Satoshi Akaishi Noriko Aramaki-Hattori Teruyuki Dohi Toshihiko Hayashi Kazuo Kishi Taro Kono Hajime Matsumura Gan Muneuchi Naoki Murao Munetomo Nagao Keisuke Okabe Fumiaki Shimizu Mamiko Tosa Yasuyoshi Tosa Satoko Yamawaki Shinichi Ansai Norihisa Inazu Toshiko Kamo Reiko Kazki Shigehiko Kuribayashi | 2019 | Burns & Trauma2019，7，1： | 31 |
| 3 | Shear wave velocity is a useful marker for managing nonalcoholic steatohepatitis显示文摘AIM:To investigate whether a noninvasive measurement of tissue strain has a potential usefulness for management of nonalcoholic steatohepatitis(NASH).METHODS:In total 26 patients,23 NASHs and 3 normal controls were enrolled in this study.NASH was staged based on Brunt criterion.At a region of interest(ROI),a shear wave was evoked by implementing an acoustic radiation force impulse(ARFI),and the propagation velocity was quantif ied.RESULTS:Shear wave velocity(SWV) could be reproducibly quantified at all ROIs in all subjects except for 4 NASH cases,in which a reliable SWV value was not calculated at several ROIs.An average SWV of 1.34 ± 0.26 m/s in fibrous stage 0-1 was significantly slower than 2.20 ± 0.74 m/s and 2.90 ± 1.01 m/s in stages 3 and 4,respectively,but was not significantly different from 1.79 ± 0.78 m/s in stage 2.When a cutoff value was set at 1.47 m/s,receiver operating characteristic analysis showed significance to dissociate stages 3 and 4 from stage 0-1(P=0.0092) with sensitivity,specificity and area under curve of 100%,75% and 94.2%,respectively.In addition,the correlation between SWV and hyaluronic acid was significant(P<0.0001),while a tendency toward negative correlation was observed with serum albumin(P=0.053).CONCLUSION:The clinical implementation of ARFI provides noninvasive repeated evaluations of liver stiffness at an arbitrary position,which has the potential to shed new light on NASH management. | Akihiko Osaki Tomoyuki Kubota Takeshi Suda Masato Igarashi Keisuke Nagasaki Atsunori Tsuchiya Masahiko Yano Yasushi Tamura Masaaki Takamura Hirokazu Kawai Satoshi Yamagiwa Toru Kikuchi Minoru Nomoto Yutaka Aoyagi | 2010 | World Journal of Gastroenterology2010，16，23： | 30 |
| 4 | Useful detection of CD147 (EMMPRIN) for pathological diagnosis of early hepatocellular carcinoma in needle biopsy samples显示文摘AIM:To make clear whether CD147 (EMMPRIN) expression in pathological tumor samples with a fine-needle aspiration biopsy is useful for pathological diagnosis of early hepatocellular carcinoma (HCC). METHODS:Twenty-two patients (15 men and 7 women; median age 68 years,range 56-81 years) underwent a liver tissue biopsy in order to make a diagnosis of HCC. Paraffin-embedded liver biopsy tissue samples from 22 patients were stained with anti-CD147 antibody,murine monoclonal antibody 12C3 (MAb12C3) for immunohistochemical analysis. An immunohistochemical analysis of CD147 was performed and the degree of staining compared between tumor and non-tumor tissue. In addition,the degree of staining within tumor tissue was compared according to a number of clinicopathological variables. RESULTS:The degree of staining of CD147 was significantly higher in tumor tissues than non-tumor tissues,even in tumors less than 15 mm in diameter.The expression of this protein was significantly elevated in HCC tissue specimens from patients with a low value of serum AST and γ-GTP. | Satoshi Mamori Keisuke Nagatsuma Tomokazu Matsuura Kiyoshi Ohkawa Hiroshi Hano Masaharu Fukunaga Masato Matsushima Yoshifumi Masui Nao Fushiya Hiroshi Onoda Yasuyuki Searashi Ichiro Takagi Hisao Tajiri | 2007 | World Journal of Gastroenterology2007，13，21： | 20 |
| 5 | Leaching of phosphorus from incinerated sewage sludge ash by means of acid extraction followed by adsorption on orange waste gel显示文摘Ashes from sewage sludge incineration have a high phosphorus content, approximately 8% (W/W), which indicates a potential resource of the limiting nutrient. Incineration of sewage sludge with subsequent recovery of phosphorus is a relatively new sludge treatment technique. In this article, the leaching of phosphorus by using sulfuric acid as well as hydrochloric acid by means of several batch experiments was presented. At the same time a selective recovery of phosphorus by adsorption was also discussed. The effects of acid concentration, temperature and time on extraction were studied. The phosphorus leaching increased with the increase in acid concentration and temperature. Kinetic studies showed that the complete leaching of phosphorus took place in less than 4 h. Selective adsorption of phosphorus by using orange waste gel provided a hint for recovery of this natural resource, which eventually could meet the ever-increasing requirement for phosphorus. The overall results indicated that the incinerated sewage sludge ash can be treated with acid to efficiently recover phosphorus and thus can be considered a potentially renewable source of phosphorus. | Biplob Kumar Biswas Katsutoshi Inoue Hiroyuki Harada Keisuke Ohto Hidetaka Kawakita | 2009 | Journal of Environmental Sciences2009，21，12： | 20 |
| 6 | Non-invasive determination of hepatic steatosis by acoustic structure quantification from ultrasound echo amplitude显示文摘AIM:To use leptin-deficient(ob/ob) mice with demonstrated differences in steatosis levels to test a new diagnostic method using the acoustical structure quantification(ASQ) mode and the associated analytical parameter,'focal disturbance ratio'(FD-ratio).METHODS:Nine ob/ob mice,at 5,8,and 12 wk of age(n = 3 in each age group),were used as models for hepatic steatosis.Echo signals obtained from ultrasonography in the mice were analyzed by ASQ,which uses a statistical analysis of echo amplitude to estimate inhomogeneity in the diagnostic region.FD-ratio,as calculated from this analysis,was the focus of the present study.FD-ratio and fat droplet areas and sizes were compared between age groups.RESULTS:No fibrosis or inflammation was observed in any of the groups.The fat droplet area significantly(P < 0.01) increased with age from 1.25% ± 0.28% at 5 wk to 31.07% ± 0.48% at 8 wk to 51.69% ± 3.19% at 12 wk.The median fat droplet size also significantly(P < 0.01) increased with age,from 1.33(0.55-10.52) m at 5 wk,2.82(0.61-44.13) m at 8 wk and 6.34(0.66-81.83) m at 12 wk.The mean FD-ratio was 0.42 ± 0.11 at 5 wk,0.11 ± 0.05 at 8 wk,and 0.03 ± 0.02 at 12 wk.The FD-ratio was significantly lower at 12 wk than at 5 wk and 8 wk(P < 0.01).A significant negative correlation was observed between the FD-ratio and either the fat droplet area(r =-0.7211,P = 0.0017) or fat droplet size(r =-0.9811,P = 0.0052).CONCLUSION:This tool for statistical analysis of signals from ultrasonography using the FD-ratio can be used to accurately quantify fat in vivo in an animal model of hepatic steatosis,and may serve as a quantitative biomarker of hepatic steatosis. | Hidekatsu Kuroda Keisuke Kakisaka Naohisa Kamiyama Takayoshi Oikawa Mio Onodera Kei Sawara Kanta Oikawa Ryujin Endo Yasuhiro Takikawa Kazuyuki Suzuki | 2012 | World Journal of Gastroenterology2012，18，29： | 15 |
| 7 | Visualizing the hepatic vascular architecture using superb microvascular imaging in patients with hepatitis C virus: A novel technique显示文摘AIM: To identify the hepatic vascular architecture of patients with hepatitis C virus(HCV) using superb microvascular imaging(SMI) and investigate the use of SMI in the evaluation of liver fibrosis.METHODS: SMI was performed in 100 HCV patients. SMI images were classified into five types according to the vascular pattern, and these patterns were compared with the fibrosis stage. Moreover, the images were analyzed to examine vascularity by integrating the number of SMI signals in the region of interest ROI [number of vascular trees(VT)]. The number of VT, fibrosis stage, serum parameters of liver function, and CD34 expression were investigated.RESULTS: There was a significant difference between SMI distribution pattern and fibrosis stage(P < 0.001). The mean VT values in each of the fibrosis stages were as follows: 26.69 ± 7.08 in F0, 27.72 ± 9.32 in F1, 36.74 ± 9.23 in F2, 37.36 ± 5.32 in F3, and 58.14 ± 14.08 in F4. The VT showed excellent diagnostic ability for F4 [area under the receiver operator characteristic(AUROC): 0.911]. The VT was significantly correlated with the CD34 labeling index(r = 0.617, P < 0.0001).CONCLUSION: SMI permitted the detailed delineation of the vascular architecture in chronic liver disease. SMI appears to be a reliable tool for noninvasively detecting significant fibrosis or cirrhosis in HCV patients. | Hidekatsu Kuroda Tamami Abe Keisuke Kakisaka Yudai Fujiwara Yuichi Yoshida Akio Miyasaka Kazuyuki Ishida Hideaki Ishida Tamotsu Sugai Yasuhiro Takikawa | 2016 | World Journal of Gastroenterology2016，22，26： | 12 |
| 8 | Chromoendoscopy of gastric adenoma using an acetic acid indigocarmine mixture显示文摘AIM:To investigate the usefulness of chromoendoscopy,using an acetic acid indigocarmine mixture(AIM),for gastric adenoma diagnosed by forceps biopsy.METHODS:A total of 54 lesions in 45 patients diagnosed as gastric adenoma by forceps biopsy were prospectively enrolled in this study and treated by endoscopic submucosal dissection(ESD)between January 2011 and January 2012.AIM-chromoendoscopy(AIMCE)was performed followed by ESD.AIM solution was sprinkled and images were recorded every 30 s for 3min.Clinical characteristics such as tumor size(<2cm,≥2 cm),surface color in white light endoscopy(WLE)(whitish,normochromic or reddish),macroscopic appearance(flat or elevated,depressed),and reddish change in AIM-CE were selected as valuables.RESULTS:En bloc resection was achieved in all 54 cases,with curative resection of fifty two lesions(96.3%).Twenty three lesions(42.6%)were diagnosed as welldifferentiated adenocarcinoma and the remaining 31lesions(57.4%)were gastric adenoma.All adenocarcinoma lesions were well-differentiated tubular adenocarcinomas and were restricted within the mucosal layer.The sensitivity of reddish color change in AIM-CE is significantly higher than that in WLE(vs tumor size≥2 cm,P=0.016,vs normochromic or reddish surface color,P=0.046,vs depressed macroscopic type,P=0.0030).On the other hand,no significant differences were found in the specificity and accuracy.In univariate analysis,normochromic or reddish surface color in WLE(OR=3.7,95%CI:1.2-12,P=0.022)and reddish change in AIM-CE(OR=14,95%CI:3.8-70,P<0.001)were significantly related to diagnosis of early gastric cancer(EGC).In multivariate analysis,only reddish change in AIM-CE(OR=11,95%CI:2.3-66,P=0.0022)was a significant factor associated with diagnosis of EGC.CONCLUSION:AIM-CE may have potential for screening EGC in patients initially diagnosed as gastric adenoma by forceps biopsy. | Yoshiyasu Kono Ryuta Takenaka Yoshiro Kawahara Hiroyuki Okada Keisuke Hori Seiji Kawano Yasushi Yamasaki Koji Takemoto Takayoshi Miyake Shigeatsu Fujiki Kazuhide Yamamoto | 2014 | World Journal of Gastroenterology2014，20，17： | 12 |
| 9 | Frequent loss of heterozygosity in two distinct regions,8p23.1 and 8p22, in hepatocellular carcinoma显示文摘AIM: To identify the precise location of putative tumor suppressor genes (TSGs) on the short arm of chromo- some 8 in patients with hepatocellular carcinoma (HCC). METHODS: We used 16 microsatellite markers informative in Japanese patients, which were selected from 61 pub- lished markers, on 8p, to analyze the frequency of loss of heterozygosity (LOH) in each region in 33 cases (56 lesions) of HCC. RESULTS: The frequency of LOH at 8p23.2-21 with at least one marker was 63% (20/32) in the informative cases. More specifically, the frequency of LOH at 8p23.2, 8p23.1, 8p22, and 8p21 was 6%, 52%, 47%, and 13% in HCC cases. The LOH was significantly more frequent at 8p23.1 and 8p22 than the average (52% vs 22%, P = 0.0008; and 47% vs 22%, P = 0.004, respectively) or others sites, such as 8p23.2 (52% vs 6%, P = 0.003; 47% vs 22%, P = 0.004) and 8p21 (52% vs 13%, P = 0.001; 47% vs 13%, P = 0.005) in liver cancer on the basis of cases. Notably, LOH frequency was significantly higher at D8S277, D8S503, D8S1130, D8S552, D8S254 and D8S258 than at the other sites. However, no allelic loss was detected at any marker on 8p in the lesions of nontumor liver tissues. CONCLUSION: Deletion of 8p, especially the loss of 8p23.1-22, is an important event in the initiation or promotion of HCC. Our results should be useful in identi- fying critical genes that might lie at 8p23.1-22. | Tomoe Lu Hiroshi Hano Keisuke Nagatsuma Satoru Chiba Masahiro Ikegami | 2007 | World Journal of Gastroenterology2007，13，7： | 12 |
| 10 | DNA methylation in gastric cancer, related to Helicobacter pylori and Epstein-Barr virus显示文摘Gastric cancer is a leading cause of cancer death worldwide,and significant effort has been focused on clarifying the pathology of gastric cancer.In particular,the development of genome-wide analysis tools has enabled the detection of genetic and epigenetic alterations in gastric cancer;for example,aberrant DNA methylation in gene promoter regions is thought to play a crucial role in gastric carcinogenesis.The etiological viewpoint is also essential for the study of gastric cancers,and two distinct pathogens,Helicobacter pylori(H.pylori)and Epstein-Barr virus(EBV),are known to participate in gastric carcinogenesis.Chronic inflammation of the gastric epithelium due to H.pylori infection induces aberrant polyclonal methylation that may lead to an increased risk of gastric cancer.In addition,EBV infection is known to cause extensive methylation,and EBV-positive gastric cancers display a high methylation epigenotype,in which aberrant methylation extends to not only Polycomb repressive complex(PRC)-target genes in embryonic stem cells but also non-PRC-target genes.Here,we review aberrant DNA methylation in gastric cancer and the association between methylation and infection with H.pylori and EBV. | Keisuke Matsusaka Sayaka Funata Masashi Fukayama Atsushi Kaneda | 2014 | World Journal of Gastroenterology2014，20，14： | 12 |
| 11 | Immunotherapy for colorectal cancer显示文摘The incidence of colorectal cancer(CRC)is on the rise,and the prognosis for patients with recurrent or metastatic disease is extremely poor.Although chemotherapy and radiation therapy can improve survival rates,it is imperative to integrate alternative strategies such as immunotherapy to improve outcomes for patients with advanced CRC.In this review,we will discuss the effect of immunotherapy for inducing cytotoxic T lymphocytes and the major immunotherapeutic approaches for CRC that are currently in clinical trials,including peptide vaccines,dendritic cell-based cancer vaccines,whole tumor cell vaccines,viral vector-based cancer vaccines,adoptive cell transfer therapy,antibody-based cancer immunotherapy,and cytokine therapy.The possibility of combination therapies will also be discussed along with the challenges presented by tumor escape mechanisms. | Shigeo Koido Toshifumi Ohkusa Sadamu Homma Yoshihisa Namiki Kazuki Takakura Keisuke Saito Zensho Ito Hiroko Kobayashi Mikio Kajihara Kan Uchiyama Seiji Arihiro Hiroshi Arakawa Masato Okamoto Jianlin Gong Hisao Tajiri | 2013 | World Journal of Gastroenterology2013，19，46： | 11 |
| 12 | Prognosis of ulcerative colitis differs between patients with complete and partial mucosal healing, which can be predicted from the platelet count显示文摘AIM:To determine the difference in clinical outcome between ulcerative colitis(UC)patients with Mayo endoscopic subscore(MES)0 and those with MES 1.METHODS:UC patients with sustained clinical remission of 6 mo or more at the time of colonoscopy were examined for clinical outcomes and the hazard ratios of clinical relapse according to MES.Parameters,including blood tests,to identify predictive factors for MES 0and slight endoscopic recurrence in clinically stablepatients were assessed.Moreover,a receiver operating characteristic curve was generated,and the area under the curve was calculated to indicate the utility of the parameters for the division between complete and partial mucosal healing.All P values were two-sided and considered significant when less than 0.05.RESULTS:A total of 183 patients with clinical remission were examined.Patients with MES 0(complete mucosal healing:n=80,44%)were much less likely to relapse than those with MES 1(partial mucosal healing:n=89,48%)(P<0.0001,log-rank test),and the hazard ratio of risk of relapse in patients with MES 1 vs MES0 was 8.17(95%CI:4.19-17.96,P<0.0001).The platelet count(PLT)<26×104/μL was an independent predictive factor for complete mucosal healing(OR=4.1,95%CI:2.15-7.99).Among patients with MES 0 at the initial colonoscopy,patients of whom colonoscopy findings shifted to MES 1 showed significant increases in PLT compared to those who maintained MES 0(3.8×104/μL vs-0.6×104/μL,P<0.0001).CONCLUSION:The relapse rate differed greatly between patients with complete and partial mucosal healing.A shift from complete to partial healing in clinically stable UC patients can be predicted by monitoring PLT. | Asuka Nakarai Jun Kato Sakiko Hiraoka Toshihiro Inokuchi Daisuke Takei Yuki Moritou Mitsuhiro Akita Sakuma Takahashi Keisuke Hori Keita Harada Hiroyuki Okada Kazuhide Yamamoto | 2014 | World Journal of Gastroenterology2014，20，48： | 11 |
| 13 | Helicobacter pylori infection in subjects negative for high titer serum antibody显示文摘AIM To investigate the clinicopathological features of the patients testing negative for high titer serum antiHelicobacter pylori(H. pylori) antibody.METHODS The antibody titers were measured using antigens derived from Japanese individuals. ^(13)C-urea breath test-positive individuals were defined as having H. pylori infection. We investigated the demographic characteristics, laboratory data, endoscopic findings including Kyoto classification of gastritis, and histology in negative-high titer patients without H. pylori eradication therapy. Kyoto classification consisted of scores for gastric atrophy, intestinal metaplasia, enlarged folds, nodularity, and redness.RESULTS Of the 136 subjects enrolled, 23(17%) had H. pylori infection. Kyoto classification had an excellent area under the receiver operating characteristics curve(0.886, 95% confidence interval: 0.803-0.968, P = 3.7 × 10^(-20)) for predicting H. pylori infection with a cutoff value of 2. Further, Kyoto classification, H. pylori density, and neutrophil activity had high accuracies(89.7%, 96.3%, and 94.1%, respectively). Kyoto classification was independent of the demographic and laboratory parameters in multivariate analysis.CONCLUSION Endoscopic Kyoto classification of gastritis is a useful predictor of H. pylori infection in negative-high titer antibody patients. | Osamu Toyoshima Toshihiro Nishizawa Masahide Arita Yosuke Kataoka Kosuke Sakitani Shuntaro Yoshida Hiroharu Yamashita Keisuke Hata Hidenobu Watanabe Hidekazu Suzuki | 2018 | World Journal of Gastroenterology2018，24，13： | 9 |
| 14 | Serum anti-Helicobacter pylori antibody titer and its association with gastric nodularity,atrophy,and age:A cross-sectional study显示文摘AIM To clarify the role of serum anti-Helicobacter pylori(H. pylori) antibody titers in gastric cancer.METHODS In this cross-sectional study, the effect of patients' baseline characteristics and endoscopic findings on their serum antibody titers were assessed. We evaluated consecutive patients who underwent esophagogastroduodenoscopy and their first evaluation for H. pylori infection using a serum antibody test. We excluded patients with a history of eradication therapy. The participants were divided into four groups according to their E-plate serum antibody titer. Patients with serum antibody titers < 3, 3-9.9, 10-49.9, and ≥ 50 U/m L were classified into groups A, B, C, and D, respectively. RESULTS In total, 874 participants were analyzed with 70%, 16%, 8.7%, and 5.1% of them in the groups A, B, C, and D, respectively. Patients in group C were older than patients in groups A and B. Gastric open-type atrophy, intestinal metaplasia, enlarged folds, diffuse redness, and duodenal ulcers were associated with a high titer. Regular arrangements of collecting venules, fundic gland polyps, superficial gastritis, and gastroesophageal reflux disease were related to a low titer. Multivariate analysis revealed that nodularity(P = 0.0094), atrophy(P = 0.0076), and age 40-59 years(vs age ≥ 60 years, P = 0.0090) were correlated with a high serum antibody titer in H. pylori-infected patients. Intestinal metaplasia and atrophy were related to age ≥ 60 years in group C and D.CONCLUSION Serum antibody titer changes with age, reflects gastric mucosal inflammation, and is useful in predicting the risk of gastric cancer. | Osamu Toyoshima Toshihiro Nishizawa Kosuke Sakitani Tadahiro Yamakawa Yoshiyuki Takahashi Nobutake Yamamichi Keisuke Hata Yasuyuki Seto Kazuhiko Koike Hidenobu Watanabe Hidekazu Suzuki | 2018 | World Journal of Gastroenterology2018，24，35： | 9 |
| 15 | Ore-forming mechanism for the Xiaoxinancha Au-rich Cu deposit in Yanbian,Jilin Province,China:Evidence from noble gas isotope geochemistry of fluid inclusions in minerals显示文摘The Xiaoxinancha Au-rich copper deposit is one of important Au-Cu deposits along the continental margin in Eastern China. The deposit consists of two sections: the Beishan mine (North), composed of altered rocks with veinlet-dissemination sulfides and melnicovite-dominated sulfide-quartz veins, and the Nanshan mine (South), composed of pyrrhotite-dominated sulfide-quartz veins and pure sulfide veins. The isotope compositions of noble gases extracted from fluid inclusions in ore minerals, i.e. ratios of 3He/4He, 20Ne/22Ne and40Ar/36Ar are in the ranges of 4.45―0.08 Ra, 10.2―8.8 and 306―430, respectively. Fluid inclusions in minerals from the Nanshan mine have higher 3He/4He and 20Ne/22Ne ratios whereas those from the Beishan mine have lower 3He/4He ratios. The analysis of origin, and evolution of the ore fluids and its relations with the ore-forming stages and the ages of mineralization suggests that the initial hydrothermal fluids probably come from the melts generated by partial melting of oceanic crust with the participation of fluids from the mantle (mantle-plume type)/aesthenosphere. This also corresponds to the continental margin settings during the subduction of Izanagi ocaneic plate towards the palaeo-Asian continent (123―102 Ma). The veinlet-dissemination ore bodies of the Beishan mine were formed through replacement and crystallization of the mixed fluids generated by mixing of the ascending high-temperature boiling fluid with young crustal fluid whereas the melnicovite-dominated sulfide-quartz veins were formed subsequently by filling of the high-temperature ore fluid in fissures. Pyrrhotite-dominated sulfide-quartz veins in the Nanshan mine were formed by filling-deposition-crystallization of the moderate-temperature ore fluids and the pure sulfide veins were formed later by filling-deposition-crystallization of ore substance-rich fluids after boiling of the moderate-temperature ore fluids. The metallogenic dynamic processes can be summarized as: (1) formation of fluidand ore substance-bearing Adakitic magma by degassing, dewatering and partial melting during subduction of the Izanagi plate; (2) separation and formation of ore fluids from the Adakitic magma; and (3) success-sive ascending of the ore fluids and final formation of the Au-rich Cu deposit of veinlet-dissemination and vein types by secondary boiling. | KEISUKE Nagao HIROCHIKA Sumino | 2008 | Science China Earth Sciences2008，51，2： | 9 |
| 16 | Excessive portal flow causes graft failure in extremely small-for-size liver transplantation in pigs显示文摘AIM: To evaluate the effects of a portocaval shunt on the decrease of excessive portal flow for the prevention of sinusoidal microcirculatory injury in extremely smallfor-size liver transplantation in pigs.METHODS: The right lateral lobe of pigs, i.e. the 25%of the liver, was transplanted orthotopically. The pigs were divided into two groups: graft without portocaval shunt (n = 11) and graft with portocaval shunt (n=11).Survival rate, portal flow, hepatic arterial flow, and histological findings were investigated.RESULTS: In the group without portocaval shunt, all pigs except one died of liver dysfunction within 24 h after transplantation. In the group with portocaval shunt,eight pigs survived for more than 4 d. The portal flow volumes before and after transplantation in the group without portocaval shunt were 118.2±26.9 mL/min/100 g liver tissue and 270.5±72.9 mL/min/100 g liver tissue,respectively. On the other hand, in the group with portocaval shunt, those volumes were 124.2±27.8 mL/min/100 g liver tissue and 42.7±32.3 mL/min/100 g liver tissue, respectively (P<0.01). As for histological findings in the group without portocaval shunt, destruction of the sinusoidal lining and bleeding in the peri-portal areas were observed after reperfusion, but these findings were not recognized in the group with portocaval shunt.CONCLUSION: These results suggest that excessive portal flow is attributed to post transplant liver dysfunction after extreme small-for-size liver transplantation caused by sinusoidal microcirculatory injury. | Hong-Sheng Wang Nobuhiro Ohkohchi Yoshitaka Enomoto Masahiro Usuda Shigehito Miyagi Takeshi Asakura Hiroo Masuoka Takashi Aiso Keisuke Fukushima Tomohiro Narita Hideyuki Yamaya Atsushi Nakamura Satoshi Sekiguchi Naoki Kawagishi Akira Sato Susumu Satomi | 2005 | World Journal of Gastroenterology2005，11，44： | 8 |
| 17 | Comparison of PPIs and H_2-receptor antagonists plus prokinetics for dysmotility-like dyspepsia显示文摘AIM:To compare efficacy of proton pump inhibitors(PPIs)with H2-receptor antagonists(H2RAs)plus prokinetics(Proks)for dysmotility-like symptoms in functional dyspepsia(FD).METHODS:Subjects were randomized to receive openlabel treatment with either rabeprazole 10 mg od(n= 57)or famotidine 10 mg bid plus mosapride 5 mg tid(n=57)for 4 wk.The primary efficacy endpoint was change(%)from baseline in total dysmotility-like dyspepsia symptom score.The secondary efficacy endpoint was patient satisfaction with treatment.RESULTS:The improvement in dysmotility-like dyspep-sia symptom score on day 28 was significantly greater in the rabeprazole group(22.5%±29.2%of baseline) than the famotidine+mosapride group(53.2%± 58.6%of baseline,P<0.0001).The superior benefit of rabeprazole treatment after 28 d was consistent regardless of Helicobacter pylori status.Significantly more subjects in the rabeprazole group were satisfied or very satisfied with treatment on day 28 than in the famotidine+mosapride group(87.7%vs 59.6%,P= 0.0012).Rabeprazole therapy was the only significant predictor of treatment response(P<0.0001),defined as a total symptom score improvement≥50%.CONCLUSION:PPI monotherapy improves dysmotility-like symptoms significantly better than H2RAs plus Proks,and should be the treatment of first choice for Japanese FD. | Masahiro Sakaguchi Miyuki Takao Yasuo Ohyama Hiroshi Oka Hiroshi Yamashita Takumi Fukuchi Kiyoshi Ashida Masahiro Murotani Masuyo Murotani Kazuo Majima Hiroshi Morikawa Takashi Hashimoto Keisuke Kiyota Hirohiko Esaki Kanji Amemoto Gouhei Isowa Fumiyuki Takao | 2012 | World Journal of Gastroenterology2012，18，13： | 8 |
| 18 | A CIN-like TCP transcription factor(LsTCP4)having retrotransposon insertion associates with a shift from Salinas type to Empire type in crisphead lettuce(Lactuca sativa L.)显示文摘To improve several agronomic traits in crisphead lettuce(Lactuca sativa L.)under high-temperature growth conditions,we investigated the correlation among those traits in multiple cultivars and performed genetic mapping of their causal genes.In a field cultivation test of Empire type(serrated leaf)and Salinas type(wavy leaf)cultivars,Empire type cultivars showed increased tipburn susceptibility and late bolting compared with Salinas type cultivars.We attempted genetic mapping of leaf shape and bolting time by ddRAD-seq using the F2 population derived from a cross between‘VI185’(Empire type)and‘ShinanoGreen’(Salinas type).These analyses suggested that both traits are controlled by a single locus in LG5.Genotyping of 51 commercial lettuce cultivars with a tightly linked marker(LG5_v8_252.743Mbp)at this locus showed an association between its genotype and the serrated leaf phenotype.By further fine mapping and transcriptome analysis,a gene encoding putative CIN-like TCP transcription factor was determined to be a candidate gene at this locus and was designated as LsTCP4.An insertion of retrotransposable element was found in the allele of‘VI185’,and its transcript level in the leaves was lower than that in‘ShinanoGreen’.Because shapes of leaf epidermal cells in‘VI185’were similar to those in the TCP family mutant of Arabidopsis thaliana,the leaf shape phenotype was likely caused by reduced expression of LsTCP4.Furthermore,because it is known that the TCP family protein also controls flowering time via interaction with FT in A.thaliana,it was highly possible that LsTCP4 gave pleiotropic effects on both leaf shape and bolting time in lettuce. | Kousuke Seki Kenji Komatsu Keisuke Tanaka Masahiro Hiraga Hiromi Kajiya-Kanegae Hideo Matsumura Yuichi Uno | 2020 | Horticulture Research2020，7，1： | 7 |
| 19 | Factors correlating with acoustic radiation force impulse elastography in chronic hepatitis C显示文摘AIM: To investigate the factors other than fibrosis stage correlating with acoustic radiation force impulse(ARFI) elastograpy in chronic hepatitis C. METHODS: ARFI elastograpy was performed in 108 consecutive patients with chronic hepatitis C who underwent a liver biopsy. The proportion of fibrosis area in the biopsy specimens was measured by computerassisted morphometric image analysis. RESULTS: ARFI correlated significantly with fibrosis stage(β = 0.1865, P < 0.0001) and hyaluronic acid levels(β = 0.0008, P = 0.0039) in all patients by multiple regression analysis. Fibrosis area correlated significantly with ARFI by Spearman's rank correlation test but not by multiple regression analysis. ARFI correlated significantly with body mass index(BMI)(β =-0.0334, P = 0.0001) in F 0 or F 1, with γ-glutamyltranspeptidase levels(β = 0.0048, P = 0.0012) in F 2, and with fibrosis stage(β = 0.2921, P = 0.0044) and hyaluronic acid levels(β = 0.0012, P = 0.0025) in F 3 or F 4. The ARFI cutoff value was 1.28 m/s for F ≥ 2, 1.44 m/s for F ≥ 3, and 1.73 m/s for F 4. CONCLUSION: ARFI correlated with fibrosis stage and hyaluronic acid but not with inflammation. ARFI was affected by BMI, γ-glutamyltranspeptidase, and hyaluronic acid in each fibrosis stage. | Toru Nishikawa Senju Hashimoto Naoto Kawabe Masao Harata Yoshifumi Nitta Michihito Murao Takuji Nakano Yuko Mizuno Hiroaki Shimazaki Toshiki Kan Kazunori Nakaoka Yuka Takagawa Masashi Ohki Naohiro Ichino Keisuke Osakabe Kentaro Yoshioka | 2014 | World Journal of Gastroenterology2014，20，5： | 7 |
| 20 | A new index for non-invasive assessment of liver fibrosis显示文摘AIM:To construct and evaluate a new non-invasive fibrosis index for assessment of the stage of liver f ibrosis. METHODS:A new f ibrosis index (Fibro-Stiffness index) was developed in 165 of 285 patients with chronic hepatitis C, and was validated in the other 120 patients where liver biopsy was performed. Its usefulness was compared with liver stiffness (LS) measured by FibroScan, the aminotransferase-to-platelet ratio index, the Forns index and the FibroIndex. RESULTS: The Fibro-Stiffness index consists of LS,platelet count and prothrombin time. The values of the Fibro-Stiffness index differed signif icantly between neighboring f ibrosis stages except F0-F1. The area under the receiver operating characteristics curves of the Fibro-Stiffness index for prediction of F≥2 (0.90), F≥ 3 (0.90) and F= 4(0.92) in the estimation group and those for F≥ 3 (0.93) and F =4 (0.97) in the validation group were the highest among the 5 methods examined. The accuracy of the Fibro-Stiffness index had highest values for F≥2, F≥3 and F=4 in both the estimation and validation groups. The diagnostic performance for F= 4 was improved by a combination of the Fibro-Stiffness index with serum hyaluronic acid level. CONCLUSION: The Fibro-Stiffness index was constructed and validated. It showed superior diagnostic performance to other indices for F ≥ 2,3 and 4. | Naohiro Ichino Keisuke Osakabe Toru Nishikawa Hiroko Sugiyama Miho Kato Shiho Kitahara Senju Hashimoto Naoto Kawabe Masao Harata Yoshifumi Nitta Michihito Murao Takuji Nakano Yuko Arima Hiroaki Shimazaki Koji Suzuki Kentaro Yoshioka | 2010 | World Journal of Gastroenterology2010，16，38： | 7 |
