| 2 | Alterations in the human epidermal growth factor receptor 2-phosphatidylinositol 3-kinase-v-Akt pathway in gastric cancer显示文摘AIM:To investigate human epidermal growth factor receptor 2(HER2)-phosphatidylinositol 3-kinase(PI3K)-vAkt murine thymoma viral oncogene homolog signaling pathway.METHODS:We analyzed 231 formalin-fixed,paraffinembedded gastric cancer tissue specimens from Japanese patients who had undergone surgical treatment.The patients' age,sex,tumor location,depth of invasion,pathological type,lymph node metastasis,and pathological stage were determined by a review of the medical records.Expression of HER2 was analyzed by immunohistochemistry(IHC) using the HercepTest TM kit.Standard criteria for HER2 positivity(0,1+,2+,and 3+) were used.Tumors that scored 3+ were considered HER2-positive.Expression of phospho Akt(pAkt) was also analyzed by IHC.Tumors were considered pAkt-positive when the percentage of positive tumor cells was 10% or more.PI3K,catalytic,alpha polypeptide(PIK3CA) mutations in exons 1,9 and 20 were analyzed by pyrosequencing.Epstein-Barr virus(EBV) infection was analyzed by in situ hybridization targeting EBV-encoded small RNA(EBER) with an EBER-RNA probe.Microsatellite instability(MSI) was analyzed by polymerase chain reaction using the mononucleotide markers BAT25 and BAT26.RESULTS:HER2 expression levels of 0,1+,2+ and 3+ were found in 167(72%),32(14%),12(5%) and 20(8.7%) samples,respectively.HER2 overexpression(IHC 3+) significantly correlated with intestinal histological type(15/20 vs 98 /205,P = 0.05).PIK3CA mutations were present in 20 cases(8.7%) and significantly correlated with MSI(10/20 vs 9/211,P < 0.01).The mutation frequency was high(21%) in T4 cancers and very low(6%) in T2 cancers.Mutations in exons 1,9 and 20 were detected in 5(2%),9(4%) and 7(3%) cases,respectively.Two new types of PIK3CA mutation,R88Q and R108H,were found in exon1.All PIK3CA mutations were heterozygous missense singlebase substitutions,the most common being H1047R(6/20,30%) in exon20.Eighteen cancers(8%) were EBV-positive and this positivity significantly correlated with a diffuse histological type(13/18 vs 93/198,P = 0.04).There were 7 cases of lymphoepithelioma-like carcinomas(LELC) and 6 of those cases were EBV-positive(percent/EBV:6/18,33%;percent/all LELC:6/7,86%).pAkt expression was positive in 119(53%) cases but showed no correlation with clinicopathological characteristics.pAkt expression was significantly correlated with HER2 overexpression(16/20 vs 103/211,P < 0.01) but not with PIK3CA mutations(12/20 vs 107/211,P = 0.37) or EBV infection(8/18 vs 103/211,P = 0.69).The frequency of pAkt expression was higher in cancers with exon20 mutations(100%) than in those with exon1(40%) or exon9(56%) mutations.One case showed both HER2 overexpression and EBV infection and 3 cases showed both PIK3CA mutations and EBV infection.However,no cases showed both PIK3CA mutations and HER2 overexpression.One EBVpositive cancer with PIK3CA mutation(H1047R) was MSI-positive.Three of these 4 cases were positive for pAkt expression.In survival analysis,pAkt expression significantly correlated with a poor prognosis(hazard ratio 1.75;95%CI:1.12-2.80,P = 0.02).CONCLUSION:HER2 expression,PIK3CA mutations and EBV infection in gastric cancer were characterized.pAkt expression significantly correlates with HER2 expression and with a poor prognosis. | Yasutaka Sukawa Hiroyuki Yamamoto Katsuhiko Nosho Hiroaki Kunimoto Hiromu Suzuki Yasushi Adachi Mayumi Nakazawa Takayuki Nobuoka Mariko Kawayama Masashi Mikami Takashi Matsuno Tadashi Hasegawa Koichi Hirata Kohzoh Imai Yasuhisa Shinomura | 2012 | World Journal of Gastroenterology2012,18,45: | 19 |
| 3 | Factors affecting recurrence after surgery for Crohn's disease显示文摘Although in Crohn's disease post-operative recurrence is common, the determinants of disease recurrence remain speculative. The aim of this study was to examine factors affecting post-operative recurrence of Crohn's disease. A Medline-based literature review was carried out. The following factors were investigated: age at onset of disease, sex, family history of Crohn's disease,smoking, duration of Crohn's disease before surgery,prophylactic medical treatment (corticosteroids, 5-amino salicylic acid [5-ASA] and immunosuppressants),anatomical site of involvement, indication for surgery (perforating or non-perforating disease), length of resected bowel, anast-omotic technique, presence of granuloma in the specimen, involvement of disease at the resection margin, blood transfusions and postoperative complications. Smoking significantly increases the risk of recurrence (risk is approximately twice as high), especially in women and heavy smokers. Quitting smoking reduces the post-operative recurrence rate. A number of studies have shown a higher risk when the duration of the disease before surgery was short. There were, however, different definitions of 'short' among the studies. Prophylactic cortic-osteroids therapy is not effective in reducing the post-operative recurrence. A number of randomized controlled trials offered evidence of the efficacy of 5-ASA (mesalazine) in reducing post-operative recurrence. Recently, the thera-peutic efficacy of immunosuppressive drugs (azathioprine and 6-mercaptopurine) in the prevention of post-operative recurrence has been investigated and several studies have reported that these drugs might help prevent the recurrence. Further clinical trials would be necessary to evaluate the prophylactic efficacy of immunosuppressants.Several studies showed a higher recurrence rate in patients with perforating disease than in those with non-perforating disease. However, evidence for differing recurrence rates in perforating and non-perforating diseases is inconclusive.A number of retrospective studies reported that a stapled functional end-to-end anastomosis was associated with a lower recurrence rate compared with other types of anastomosis. However, prospective randomized studies would be necessary to draw a definite conclusion. Many studies found no difference in the recurrence rates between patients with radical resection and non-radical resection. Therefore, minimal surgery including strictureplasty has been justified in the management of Crohn's disease. In this review, the following factors do not seem to be predictive of post-operative recurrence:age at onset of disease, sex, family history of Crohn's disease, anatomical site of disease, length of resected bowel, presence of granuloma in the specimen, blood transfusions and post-operative complications. The most significant factor affecting post-operative recurrence of Crohn's disease is smoking. Smoking significantly increases the risk of recurrence. A short disease duration before surgery seems, albeit to a very minor degree, to be associated with a higher recurrence rate. 5-ASA has been shown with some degree of confidence to lead to a lower recurrence rate. The prophylactic efficacy of immunosuppressive drugs should be assessed in future.A wider anastomotic technique after resection may reduce the post-operative recurrence rate, though this should be investigated with prospective randomized controlled trials. | Takayuki Yamamoto | 2005 | World Journal of Gastroenterology2005,11,26: | 17 |
| 4 | A combination treatment of entecavir and early-phase corticosteroid in severe exacerbation of chronic hepatitis B显示文摘Of patients with severe exacerbation of chronic hepatitis B accompanied by jaundice and coagulopathy,20%-30%have a fatal outcome.In this report,we describe 2 cases of severe exacerbation of chronic hepatitis B with jaundice and coagulopathy who were successfully treated with a combination of entecavir and corticosteroid.In both cases,rapid reductions in serum hepatitis B virus(HBV)-DNA levels were observed,and corticosteroid was stopped after serum HBV-DNA levels became undetectable.Entecavir treatment was continued.Generally,entecavir treatment reduced serum HBV-DNA levels rapidly,although the improvement in liver function was delayed by a few weeks.During this time lag,liver cell injury continued and the disease progressed.Corticosteroid suppressed the excessive host immune response and was useful for stopping progressive deterioration.A combination of entecavir and early-phase corticosteroid may be a useful treatment in severe exacerbation of chronic hepatitis B. | Kazuyuki Matsumoto Yasuhiro Miyake Hirokazu Miyatake Masahiro Takahara Takayuki Imada Satoru Yagi Tatsuya Toyokawa Morihito Nakatsu Masaharu Ando Mamoru Hirohata | 2009 | World Journal of Gastroenterology2009,15,13: | 16 |
| 5 | Comparative study: Vonoprazan and proton pump inhibitors in Helicobacter pylori eradication therapy显示文摘AIM To compare the effectiveness and safety of vonoprazan-based therapy with proton pump inhibitor(PPI)-based therapies to treat Helicobacter pylori(H. pylori).METHODS We retrospectively analysed data from first-line(vonoprazan or PPI with 200 mg clarithromycin and 750 mg amoxicillin twice daily for 7 d)(n = 1353) and second-line(vonoprazan or PPI with 250 mg metronidazole and 750 mg amoxicillin twice daily for 7 d)(n = 261) eradication treatments for H. pylori- positive patients with associated gastrointestinal diseases from April 2014 to December 2015 at Hattori Clinic, Japan. The primary endpoint was the eradication rate, which was assessed with a full analysis set. The secondary endpoints were adverse events and related factors.RESULTS After the first-line treatments, the eradication rates for vonoprazan, esomeprazol, rabeprazole, and lansoprazole were 87.9%(95%CI: 84.9%-90.5%), 71.6%(95%CI: 67.5%-75.5%), 62.9%(95%CI: 52.0%-72.9%), and 57.3%(95%CI: 50.4%-64.1%), respectively. The vonoprazan eradication rate was significantly higher than that of the PPIs(P < 0.01). Interestingly, smoking did not affect the H. pylori eradication rate in the vonoprazan group(P = 0.34), whereas it decreased the rates in the PPI groups(P = 0.013). The incidence of adverse events in the vonop-razan group was not different from the PPI group(P = 0.054), although the vonoprazan group exhibited a wider range of adverse events. Vonoprazan-based triple therapy was highly effective as a second-line treatment, with an eradication rate similar to that of PPI-based therapy.CONCLUSION Vonoprazan might be superior to PPIs in first-line H. pylori therapy, particularly for smokers. However, caution is required due to possible adverse events. | Kouichi Sakurai Hiroko Suda Yumi Ido Takayuki Takeichi Ayako Okuda Kiwamu Hasuda Masahiro Hattori | 2017 | World Journal of Gastroenterology2017,23,4: | 16 |

| 8 | Inflammatory pseudotumor of the liver and spleen diagnosed by percutaneous needle biopsy显示文摘An inflammatory pseudotumor (IPT) is a relatively rare lesion characterized by chronic inf iltration of inflammatory cells and areas of f ibrosis. IPTs are diff icult to diagnose because of the absence of specif ic symptoms or of characteristic hematological or radiological f indings. In this study, a case of a woman aged over 70 years was reported, who presented with a general malaise lasting more than two months. A computed tomography scan demonstrated a diffusely spread lesion of the liver with a portal vein occlusion and a splenic lesion surrounded by a soft density layer. Since the percutaneous liver biopsy showed f indings that suggested an IPT, although the radiological f indings did not exclude the possibility of a malignancy, we performed a percutaneous spleen biopsy to enable a more defi nitive diagnosis. The microscopic f indings from the spleen specimen lead us to a diagnosis of IPT involving the liver and spleen. Sub-sequent steroid pulse therapy was effective, and rapid resolution of the disease was observed. | Tsukasa Kawaguchi Kiyoshi Mochizuki Takashi Kizu Masanori Miyazaki Takayuki Yakushijin Shusaku Tsutsui Eiichi Morii Tetsuo Takehara | 2012 | World Journal of Gastroenterology2012,18,1: | 11 |
| 9 | Treating inflammatory bowel disease by adsorptive leucocytapheresis:A desire to treat without drugs显示文摘Ulcerative colitis and Crohn’s disease are the major phenotypes of the idiopathic inflammatory bowel disease(IBD),which afflicts millions of individuals throughout the world with debilitating symptoms,impairing function and quality of life.Current medications are aimed at reducing the symptoms or suppressing exacerbations.However,patients require life-long medications,and this can lead to drug dependency,loss of response together with adverse side effects.Indeed,drug side effects become additional morbidity factor in many patients on long-term medications.Nonetheless,the efficacy of anti-tumour necrosis factors(TNF)-αbiologics has validated the role of inflammatory cytokines notably TNF-αin the exacerbation of IBD.However,inflammatory cytokines are released by patients’own cellular elements including myeloid lineage leucocytes,which in patients with IBD are elevated with activation behaviour and prolonged survival.Accordingly,these leucocytes appear logical targets of therapy and can be depleted by adsorptive granulocyte/monocyte apheresis(GMA)with an Adacolumn.Based on this background,recently GMA has been applied to treat patients with IBD in Japan and in the European Union countries.Efficacy rates have been impressive as well as disappointing.In fact the clinical response to GMA seems to define the patients’disease course,response to medications,duration of active disease,and severity at entry.The best responders have been first episode cases(up to 100%)followed by steroid nave and patients with a short duration of active disease prior to GMA.Patients with deep ulcers together with extensive loss of the mucosal tissue and cases with a long duration of IBD refractory to existing medications are not likely to benefit from GMA.It is clinically interesting that patients who respond to GMA have a good long-term disease course by avoiding drugs including corticosteroids in the early stage of their IBD.Additionally,GMA is very much favoured by patients for its good safety profile.GMA in 21st century reminds us of phlebotomy as a major medical practice at the time of Hippocrates.However,in patients with IBD,there is a scope for removing from the body the sources of proinflammatory cytokines and achieve disease remission.The bottom line is that by introducing GMA at an early stage following the onset of IBD or before patients develop extensive mucosal damage and become refractory to medications,many patients should respond to GMA and avoid pharmacologics.This should fulfill the desire to treat without drugs. | Abbi R Saniabadi Tomotaka Tanaka Toshihide Ohmori Koji Sawada Takayuki Yamamoto Hiroyuki Hanai | 2014 | World Journal of Gastroenterology2014,20,29: | 11 |
| 10 | Helicobacter pylori and gastric mucosa-associated lymphoid tissue lymphoma:Recent progress in pathogenesis and management显示文摘Recent progress in the research regarding the molecular pathogenesis and management of gastric mucosaassociated lymphoid tissue(MALT)lymphoma is reviewed.In approximately 90%of cases,Helicobacter pylori(H.pylori)infection plays the causative role in the pathogenesis,and H.pylori eradication is nowadays the first-line treatment for this disease,which leads to complete disease remission in 50%-90%of cases.In H.pylori-dependent cases,microbe-generated immune responses,including interaction between B and T cells involving CD40 and CD40L co-stimulatory molecules,are considered to induce the development of MALT lymphoma.In H.pylori-independent cases,activation of the nuclear factor-κB pathway by oncogenic products of specific chromosomal translocations such as t(11;18)/API2-MALT1,or inactivation of tumor necrosis factor alpha-induced protein 3(A20)are considered to contribute to the lymphomagenesis.Recently,a largescale Japanese multicenter study confirmed that the long-term clinical outcome of gastric MALT lymphoma after H.pylori eradication is excellent.Treatment modalities for patients not responding to H.pylori eradication include a'watch and wait'strategy,radiotherapy,chemotherapy,rituximab immunotherapy,and a combination of these.Because of the indolent behavior of MALT lymphoma,second-line treatment should be tailored in consideration of the clinical stage and extent of the disease in each patient. | Shotaro Nakamura Takayuki Matsumoto | 2013 | World Journal of Gastroenterology2013,19,45: | 11 |

| 13 | Effects of 5-HT2B, 5-HT3 and 5-HT4 receptor antagonists on gastrointestinal motor activity in dogs显示文摘AIM:To study the effects of 5-hydroxytryptamine(5-HT)receptor antagonists on normal colonic motor activity in conscious dogs.METHODS:Colonic motor activity was recorded using a strain gauge force transducer in 5 dogs before and after 5-HT2B,5-HT3 and 5-HT4 receptor antagonist administration.The force transducers were implanted on the serosal surfaces of the gastric antrum,terminal ileum,ileocecal sphincter and colon.Test materials or vehicle alone was administered as an intravenous bolus injection during a quiescent period of the whole colon in the interdigestive state.The effects of these receptor antagonists on normal gastrointestinal motor activity were analyzed.RESULTS:5-HT2B,5-HT3 and 5-HT4 receptor antagonists had no contractile effect on the fasting canine terminal ileum.The 5-HT3 and 5-HT4 receptor antagonists inhibited phaseⅢof the interdigestive motor complex of the antrum and significantly inhibited colonic motor activity.In the proximal colon,the inhibitory effect was dose dependent.Dose dependency,however,was not observed in the distal colon.The 5-HT2B receptor antagonist had no contractile effect on normal colonic motor activity.CONCLUSION:The 5-HT3 and 5-HT4 receptor antagonists inhibited normal colonic motor activity.The5-HT2B receptor antagonist had no contractile effect on normal colonic motor activity. | Hiroki Morita Erito Mochiki Nobuyuki Takahashi Kiyoshi Kawamura Akira Watanabe Toshinaga Sutou Atsushi Ogawa Mitsuhiro Yanai Kyoichi Ogata Takaaki Fujii Tetsuro Ohno Souichi Tsutsumi Takayuki Asao Hiroyuki Kuwano | 2013 | World Journal of Gastroenterology2013,19,39: | 9 |
| 14 | The polyketide synthase OsPKS2 is essential for pollen exine and Ubisch body patterning in rice显示文摘Lipid and phenolic metabolism are important for pollen exine formation. In Arabidopsis, polyketide synthases(PKSs) are essential for both sporopollenin biosynthesis and exine formation. Here, we characterized the role of a polyketide synthase(OsPKS2) in male reproduction of rice(Oryza sativa). Recombinant OsPKS2 catalyzed the condensation of fatty acyl-CoA with malonyl-CoA to generate triketide and tetraketide α-pyrones, the main components of pollen exine. Indeed, the ospks2 mutant had defective exine patterning and was male sterile. However, the mutant showed no significant reduction in sporopollenin accumulation. Compared with the WT(wild type), ospks2 displayed unconfined and amorphous tectum and nexine layers in the exine, and less organized Ubisch bodies. Like the pksb/lap5 mutant of the Arabidopsis ortholog, ospks2 showed broad alterations in the profiles of anther-related phenolic compounds.However, unlike pksb/lap5, in which most detected phenolics were substantially decreased, ospks2 accumulated higher levels of phenolics. Based on these results and our observation that OsPKS2 is unable to fully restore the exine defects in the pksb/lap5, we propose that PKS proteins have functionally diversified during evolution.Collectively, our results suggest that PKSs represent a conserved and diversified biochemical pathway for anther and pollen development in higher plants. | Xiaolei Zhu Jing Yu Jianxin Shi Takayuki Tohge Alisdair R.Fernie Sagit Meir Asaph Aharoni Dawei Xu Dabing Zhang Wanqi Liang | 2017 | Journal of Integrative Plant Biology2017,59,9: | 9 |
| 15 | Cerebral lipiodol embolism related to a vascular lake during chemoembolization in hepatocellular carcinoma:A case report and review of the literature显示文摘A male patient underwent conventional transcatheter chemoembolization for advanced recurrent hepatocellular carcinoma(HCC). Even after the injection of 7 m L of lipiodol followed by gelatin sponge particles, the flow of feeding arteries did not slow down. A repeat angiography revealed a newly developed vascular lake draining into systemic veins; however, embolization was continued without taking noticing of the vascular lake. The patient's level of consciousness deteriorated immediately after the procedure, and non-contrast computed tomography revealed pulmonary and cerebral lipiodol embolisms. The patient's level of consciousness gradually improved after 8 wk in intensive care. In this case, a vascular lake emerged during chemoembolization and drained into systemic veins, offering a pathway carrying lipiodol to pulmonary vessels, the most likely cause of this serious complication. We should be aware that vascular lakes in HCC may drain into systemic veins and can cause intratumoral arteriovenous shunts. | Hideki Ishimaru Minoru Morikawa Takayuki Sakugawa Ichiro Sakamoto Yasuhide Motoyoshi Yohei Ikebe Masataka Uetani | 2018 | World Journal of Gastroenterology2018,24,37: | 9 |

| 18 | Identification of activity stop locations in GPS trajectories by density-based clustering method combined with support vector machines显示文摘The identification of activity locations in continuous GPS trajectories is an essential preliminary step in obtaining person trip data and for activity-based transportation demand forecasting.In this research,a two-step methodology for identifying activity stop locations is proposed.In the first step,an improved density-based spatial clustering of applications with noise(DBSCAN) algorithm identifies stop points and moving points;then in the second step,the support vector machines(SVMs) method distinguishes activity stops from non-activity stops among the identified stop points.A time sequence constraint and a direction change constraint are applied as improvements to DBSCAN(yielding an improved algorithm known as C-DBSCAN).Then three major features are extracted for use in the SVMs method:stop duration,mean distance to the centroid of a cluster of points at a stop location,and the shorter of distances from current location to home and to the workplace.The proposed methodology was tested using GPS data collected from mobile phones in the Nagoya area of Japan.The C-DBSCAN algorithm achieves an accuracy of 90%in identifying stop points in the first step,while the SVMs method is 96%accurate in distinguishing the locations of activity stops from non-activity stops in the second step.Compared to other variants of DBSCAN used to identify activity locations from GPS trajectories,this two-step method is generally superior. | Lei Gong Hitomi Sato Toshiyuki Yamamoto Tomio Miwa Takayuki Morikawa | 2015 | Journal of Modern Transportation2015,23,3: | 8 |

| 20 | Decrease of reactive-oxygen-producing granulocytes and release of IL-10 into the peripheral blood following leukocytapheresis in patients with active ulcerative colitis显示文摘AIM: To investigate the clinical efficacy of leukocytapheresis (LCAP) in patients with active ulcerative colitis (UC), and to elucidate the mechanisms by determining the changes in the cytokine levels in the peripheral blood and of the functions of the peripheral blood leukocytes in these patients.METHODS: The subjects were 19 patients with active UC, with a mean clinical activity index (CAI) of 9.2. The LCAP was conducted using Cellsorba E. In each session of LCAP, 2-3 L of blood at the flow rate of 30-50 mL/min was processed. The treatment was carried out in approximately 1-h sessions, once a week, for 5-10 wk. Blood samples for determination of the cytokine levels were collected from the inflow side of the column (site of dehematization; at the start of LCAP) and outflow side of the column (at the end of LCAP). Blood samples for the determination of reactive-oxygen-producing cells were collected from the peripheral blood before and after LCAP.RESULTS: LCAP resulted in clinical improvement in all the 19 patients of UC recruited for this study. Remission (CAI: ≤4) was noted in 15 (79%) of the 19 patients. The blood level of the pro-inflammatory cytoline IL-6 was found to be decreased following treatment by LCAP, and the level of the anti-inflammatory cytokine IL-10 at the outflow side of the LCAP column was found to be significantly elevated as compared to that at the inflow side of the column. The reactive-oxygen-producing granulocytes in the peripheral blood of UC patients was increased as compared to that in healthy persons and the increase was found to be decreased following treatment by LCAP.CONCLUSION: LCAP exerted a high therapeutic efficacy in patients with active UC. Our findings suggest that LCAP is associated with enhanced production of the inhibitory cytokine IL-10 to indirectly inhibit the functions of the inflammatory leukocytes, and that inflammation is also considerably attenuated by the direct removal of reactiveoxygen-producing neutrophils from the peripheral blood. | Hiroyuki Hanai Takayuki Iida Ken Takeuchi Fumitoshi Watanabe Yasuhiko Maruyama Masataka Kikuyama Tatsuo Tanaka Kenji Kondo Kou Tanaka Kenji Takai | 2005 | World Journal of Gastroenterology2005,11,20: | 7 |
