| 1 | Balloon-occluded transcatheter arterial chemoembolization for hepatocellular carcinoma显示文摘Transcatheter arterial chemoembolization(TACE) is widely accepted as a treatment for patients with hepatocellular carcinoma(HCC) in the intermediate stage according to the Barcelona Clinic Liver Cancer(BCLC) guidelines. Recently, balloon-occluded TACE(B-TACE) was developed in Japan. Despite the lack of a clear definition, B-TACE is generally defined as the infusion of emulsion of chemotherapeutic agents with lipiodol followed by gelatin particles under the occlusion of feeding arteries by a microballoon catheter, which leads to the dense lipiodol emulsion(LE) accumulation in HCC nodules. This phenomenon cannot be explained only by the prevention of proximal migration and leakage of embolization materials; it further involves causing local changes in the hemodynamics of the surrounding occlusion artery and targeted HCC nodules. Balloon-occluded arterial stump pressure plays an important role in the dense LE accumulation in targeted HCC nodules. Although randomized controlled trials comparing the therapeutic effect and the prognosis of B-TACE to those of the other TACE procedures, such as conventional-TACE and drug-eluting beads TACE, are still lacking, B-TACE is thought to be a promising treatment. The purpose of this review is to summarize the mechanism, therapeutic effect, indication, prognosis and complications of BTACE. | Takeshi Hatanaka Hirotaka Arai Satoru Kakizaki | 2018 | World Journal of Hepatology2018，10，7： | 22 |

| 3 | Short term results of endoscopic submucosal dissection in superficial esophageal squamous cell neoplasms显示文摘AIM: To evaluate the efficacy of endoscopic submucosal dissection for superficial esophageal squamous cell neoplasms. METHODS: Between July 2007 and March 2009, 27 consecutive superficial esophageal squamous cell neoplasms in 25 enrolled patients were treated by endoscopic submucosal dissection. The therapeutic efficacy, complications, and follow-up results were assessed. RESULTS: The mean size of the lesions was 21 ± 13 mm (range 2-55 mm); the mean size of the resection specimens was 32 ± 12 mm (range 10-70 mm). The enblock resection rate was 100% (27/27), and en block resection with tumor-free lateral/basal margins was 88.9% (24/27). Perforation occurred in 1 patient who was managed by conservative medical treatments. None of the patients developed local recurrence or distant metastasis in the follow-up period. CONCLUSION: Endoscopic submucosal dissection is applicable to superficial esophageal squamous cell neoplasms with promising results. | Kouichi Nonaka Shin Arai Keiko Ishikawa Masamitsu Nakao Yousuke Nakai Osamu Togawa Koji Nagata Michio Shimizu Yutaka Sasaki Hiroto Kita | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，2： | 19 |
| 4 | Can endoscopic submucosal dissection be safely performed in a smaller specialized clinic?显示文摘AIM:To investigate whether endoscopic submucosal dissection(ESD) can be safely performed at small clinics,such as the Shirakawa Clinic.METHODS:One thousand forty-seven ESDs to treat gastrointestinal tumors were performed at the Shirakawa Clinic from April 2006 to March 2011.The efficacy,technical feasibility and associated complications of the procedures were assessed.The ESD procedures were performed by five endoscopists.Sedation was induced with propofol for esophagogastorduodenal ESD.RESULTS:One thousand forty-seven ESDs were performed to treat 64 patients with esophageal cancer(E),850 patients with gastric tumors(G:764 patients with cancer,82 patients with adenomas and four others),four patients with duodenal cancer(D) and 129 patients with colorectal tumors(C:94 patients with cancer,21 patients with adenomas and 14 others).The en bloc resection rate was 94.3%(E:96.9%,G:95.8%,D:100%,C:79.8%).The median operation time was 46 min(range:4-360 min) and the mean size of the resected specimens was 18 mm(range:2-150 mm).No mortal complications were observed in association with the ESD procedures.Perforation occurred in 12 cases(1.1%,E:1 case,G:9 cases,D:1 case,C:1 case) and postoperative bleeding occurred in 53 cases(5.1%,G:51 cases,D:1 case,C:1 case);however,no case required either emergency surgery or blood transfusion.All of the perforations and postperative bleedings were resolved by endoscopic clipping or hemostasis.The other problematic complication observed was pneumonia,which was treated with conservative therapy.CONCLUSION:ESD can be safely performed in a clinic with established therapeutic methods and medical services to address potential complications. | Naondo Sohara Satoshi Hagiwara Riki Arai Haruhisa Iizuka Yasuhiro Onozato Satoru Kakizaki | 2013 | World Journal of Gastroenterology2013，19，4： | 15 |
| 5 | Prognostic value of KRAS and BRAF mutations in curatively resected colorectal cancer显示文摘AIM: To investigate the prognostic role of KRAS and BRAF mutations after adjustment for microsatellite instability(MSI) status in Japanese colorectal cancer(CRC) population.METHODS: We assessed KRAS and BRAF mutations and MSI status in 813 Japanese patients with curatively resected, stage Ⅰ-Ⅲ CRC and examined associations of these mutations with disease-free survival(DFS) and overall survival(OS) using uni- and multivariate Cox proportional hazards models.RESULTS: KRAS and BRAF mutations were detected in 312(38%) of 812 and 40(5%) of 811 tumors, respectively. KRAS mutations occurred more frequently in females than in males(P = 0.02), while the presence of BRAF mutations was significantly associated with the female gender(P = 0.006), proximal tumor location(P < 0.001), mucinous or poorly differentiated histology(P < 0.001), and MSI-high tumors(P < 0.001). After adjusting for relevant variables, including MSI status, KRAS mutations were associated with poorer DFS(HR = 1.35; 95%CI: 1.03-1.75) and OS(HR = 1.46; 95%CI: 1.09-1.97). BRAF mutations were poor prognostic factors for DFS(HR = 2.20; 95%CI: 1.19-4.06) and OS(HR = 2.30; 95%CI: 1.15-4.71). Neither the BRAF by MSI interaction test nor the KRAS by MSI interaction test yielded statistically significant results for DFS and OS.CONCLUSION: KRAS and BRAF mutations are associated with inferior survival, independent of MSI status, inJapanese patients with curatively resected CRC. | Shigenori Kadowaki Miho Kakuta Shuhei Takahashi Akemi Takahashi Yoshiko Arai Yoji Nishimura Toshimasa Yatsuoka Akira Ooki Kensei Yamaguchi Keitaro Matsuo Kei Muro Kiwamu Akagi | 2015 | World Journal of Gastroenterology2015，21，4： | 14 |
| 6 | Usefulness of anti-ulcer drugs for the prevention and treatment of peptic ulcers induced by low doses of aspirin显示文摘AIM:To investigate the usefulness of anti-ulcer drugs for the prevention and treatment of low-dose aspirin- induced peptic ulcer. METHODS:Upper gastrointestinal endoscopy was performed in 68 patients receiving daily low-dose aspirin(81 or 100 mg/day).The endoscopic findings were classified according to the Lanza score,and the scores were compared between groups categorized according to the concomitant use of anti-ulcer drugs and the types of drugs used.In another study,31 hemorrhagic peptic ulcer patients who had been receiving low-dose aspirin were enrolled.The patients were randomly classified into the proton pump inhibitor (PPI)-treated group and the H2 receptor antagonist (H2RA)-treated group.The administration of low-dose aspirin was continued concomitantly,and endoscopic examinations were performed 8 wk later. RESULTS:The Lanza scores(mean±SD)of the gastro-mucosal lesions were 1.0±1.9 and 1.9±2.3 in 8 and 16 patients receiving prevention therapy with a PPI and an H2RA,respectively.Both scores were significantly smaller than the scores in 34 patients who were not receiving prevention therapy(4.7±1.0)and in 10 patients receiving cytoprotective anti-ulcer drugs (4.3±1.6).In the prospective study,18 and 13 patients received a PPI and an H2RA,respectively.Endoscopic examinations revealed that the tissue in the region of the gastro-mucosal lesions had reverted to normal in all patients in the PPI-treated group and in 12 patients (92%)in the H2RA-treated group;no significant differences were observed between the groups. CONCLUSION:H2RA therapy was effective for both the prevention and treatment of low-dose aspirin- induced peptic ulcer,similar to the effects of PPIs, while cytoprotective anti-ulcer drugs were ineffective in preventing ulceration. | Sayaka Nakashima Shinichi Ota Shin Arai Kiyoko Yoshino Mie Inao Keiko Ishikawa Nobuaki Nakayama Yukinori Imai Sumiko Nagoshi Satoshi Mochida | 2009 | World Journal of Gastroenterology2009，15，6： | 11 |

| 8 | 基本参数法X-射线荧光光谱同时分析镍、钴和铁基合金显示文摘用基本参数法分析了镍、钴和铁基合金,对每种元素在整个含量范围内用单一校准进行了测定,并获得了满意的结果。研究显示,本方法可以采用多通道光谱仪对主次元素进行分析测定。例如,对镍元素来说,在质量分数0%到100%的浓度范围内,准确度达到质量分数0.14%。我们还发现,在铬的分析中,三级激发很显著,对整体强度的贡献率达到2.4%。通过将三级激发考虑进理论强度计算,方法的准确度可由质量分数0.14%提高到0.10%。对灵敏度进行了最小二乘拟合法校准,研究显示二次拟合多项式用单一校准曲线在整个浓度范围内都能给出很好的结果。在多通道光谱仪中,当通道不再适合谱线重叠时,理论强度重叠校正法是有效的手段。 | KATAOKA Yoshiyukki FURUSAWA Eiichi KOHNO Hisayuki ARAI Tomoya MARTIN Al INOUE Hisashi MANTLER Michael | 2009 | 冶金分析2009，29，5： | 9 |
| 9 | An advanced partitioning process for key elements separation from high level liquid waste显示文摘To separate MA(Am,Cm) and some fission product elements(FPs) such as Tc,Pd,Cs and Sr from high level liquid waste(HLLW) systematically,we have been studying an advanced aqueous partitioning process,which uses selective adsorption as the separation method.For this process,we prepared several novel adsorbents which were immobilized in a porous silica/polymer composite support(SiO 2-P).Adsorption and separation behavior of various elements was studied experimentally in detail.Small scale separation tests using simulated HLLW solutions were carried out.Pd(II) was strongly adsorbed by the AR-01 anion exchanger and effectively eluted off by using thiourea.Successful separation of Pd(II) from simulated HLLW was achieved.Tc(VII) also exhibited strong adsorption on AR-01 and could be eluted off by using U(IV) as a reductive eluent.Am(III) presented significantly high adsorbability and selectivity onto R-BTP/SiO 2-P adsorbents over various FPs including Ln(III).The R-BTP adsorbents were fairly stable in 3 M HNO 3,but instable against-irradiation-3M HNO 3.An advanced partitioning process consisting of three separation columns for the target elements separation from HLLW was proposed and the obtained experiment results indicated that the proposed process is essentially feasible. | WEI YueZhou WANG XinPeng LIU RuiQin WU Yan USUDA Shigekazu ARAI Tsuyoshi | 2012 | Science China Chemistry2012，55，9： | 9 |
| 10 | Clinical practice of transarterial chemoembolization for hepatocellular carcinoma:consensus statement from an international expert panel of International Society of Multidisciplinary Interventional Oncology(ISMIO)显示文摘Importance:Transarterial chemoembolization(TACE)has been associated with a wide range of practice variations for hepatocellular carcinoma(HCC)between the East and the West.This considerable ambiguity may lead to the heterogeneous quality in treatment and have a negative impact on the role of TACE in the overall multidisciplinary HCC treatment system.Objective:It may be a good start to establish a guideline worldwide to have this consensus from experts who represent east and west,although it does not cover all aspects of TACE.Evidence Review:An international expert panel on TACE is convened to cluster the expert’s opinions and summary a standard consensus.This panel committee consist of leading physicians in TACE on HCC from USA,France,Japan,Singapore,Korea,China,and so on.The first-round face-to-face consensus meeting was held during in Nanjing,China in October 2019.The second-round conference for revision of the consensus was held during the Annual Meeting of Chinese College of Interventionalists in August 2020 by a hybrid format of a Webinar and roundtable meeting.After several on-line revisions,the final manuscript was approved by all members of the panel in June 2021.Findings:The consensus statements were organized into the following categories:patients’selection,performing the procedure,TACE outcomes,repeat TACE,TACE failure/refractory,and TACE-based combination treatments.Conclusions and Relevance for Reviews:More and more evidences have showed the better outcomes with strategy of combined TACE with other local therapies such as ablations.The most-recently developing strategy of combined TACE with PD-1/PD-L1 plus tyrosine kinase inhibitor(TKI)agents has shined a light to the HCC patients,especially to those with high risk of tumor recurrence after treatment or TACE failure/refractory. | Jian Lu Ming Zhao Yasuaki Arai Bin-Yan Zhong Hai-Dong Zhu Xiao-Long Qi Thierry de Baere Uei Pua Hyun Ki Yoon David C.Madoff Gao-Jun Teng International Society of Multidisciplinary Interventional Oncology(ISMIO) | 2021 | Hepatobiliary Surgery and Nutrition2021，10，5： | 9 |
| 11 | 在哪个与狭窄的乐队成像放大了内视镜检查法的胃的联系 mucosa 的淋巴的组织淋巴瘤的一个盒子在诊断是有用的显示文摘 Recently, we reported a case of gastric mucosaassociated lymphoid tissue (MALT) lymphoma presenting with unique vascular features. In the report, we defined the tree-like appearance (TLA) on the images of abnormal blood vessels which resembled branches from the trunk of a tree in the shiny mucosa, in which the glandular structure was lost. The 67-year-old female was diagnosed with gastric MALT lymphoma. The patient received eradication therapy for H. pylori. Conventional endoscopy revealed multiple ill-delineated brownish depressions in the stomach and cobblestonelike mucosa was observed at the greater curvature to the posterior wall of the upper gastric body 7 mo after successful eradication. Unsuccessful treatment of gastric MALT lymphoma was suspected on conventional endoscopy. Conventional endoscopic observations found focal depressions and cobblestone-like appearance, and these lesions were subsequently observed using magnified endoscopy combined with narrow band imaging to identify abnormal vessels presenting with a TLA within the lesions. Ten biopsies were taken from the area where abnormal vessels were present within these lesions. Ten biopsies were also taken from the lesions without abnormal vessels as a control. A total of 20 biopsy samples were evaluated to determine whether the diagnosis of MALT lymphoma could be obtained histologically from each sample. A positive diagnosis was obtained in 8/10 TLA (+) sites and in 2/10 TLA(-) sites. Target biopsies of the site with abnormal blood vessels can potentially improve diagnostic accuracy of gastric MALT lymphoma. | Kouichi Nonaka Keiko Ishikawa Shin Arai Masamitsu Nakao Michio Shimizu Takaki Sakurai Koji Nagata Makoto Nishimura Osamu Togawa Yasutoshi Ochiai Yutaka Sasaki Hiroto Kita | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，4： | 8 |

| 15 | Two-week treatment with proton pump inhibitor is sufficient for healing post endoscopic submucosal dissection ulcers显示文摘AIM:To investigate the optimum period of treatment for post endoscopic submucosal dissection(ESD)ulcers.METHODS:Patients who underwent ESD for gastric cancer were randomized to two groups and treated with esomeprazole 20 mg per day for 4 wk(4W group)or 2 wk(2W group).At 4 wk after ESD,we measured the size of the artificial ulcers by endoscopy and determined the ulcer healing rate,compared with the size of the ESD specimens.This randomized controlled trial study was approved by our ethics committee and registered in the UMIN Clinical Trial Registry.RESULTS:A total of 60 consecutive patients were included in the study.All patients received rebamipide 300 mg per day for 4 wk.One patient in 2W group who showed bleeding within two weeks and received endoscopic treatment was excluded from further analysis.The numbers of patients with ulcers in the healing/scar stage in the 2W and 4W groups at 4 wk after ESD were 20/6 and 28/5,respectively,with no significant difference.The ulcer healing rate in the 2W and 4W groups were 96.1%[95%confidence interval(CI):94.6%-97.55]vs 94.8%(95%CI:92.6%-97.1%),respectively,with no statistical difference(UMIN000006951).CONCLUSION:Two-wk treatment with a proton pump inhibitor is as effective as four-week treatment for healing post ESD ulcers. | Makoto Arai Tomoaki Matsumura Kenichiro Okimoto Arata Oyamada Keiko Saito Shoko Minemura Daisuke Maruoka Takeshi Tanaka Tomoo Nakagawa Tatsuro Katsuno Osamu Yokosuka | 2014 | World Journal of Gastroenterology2014，20，43： | 6 |
| 16 | Electrochemical behavior of [UO_2Cl_4]^(2-) in 1-ethyl-3-methylimidazolium based ionic liquids显示文摘In order to examine the chemical form of uranyl species in 1-ethyl-3-methylimidazolium(EMI) based ionic liquids,UV-visible absorption spectra of solutions prepared by dissolving [EMI] 2 [UO2Cl4] into a mixture of EMICl and EMIBF 4(50:50 mol%) were measured.As a result,it was confirmed that uranyl species in the mixture of EMICl and EMIBF 4 existed as [UO2Cl4]2-.Cyclic voltammograms(CVs) of [UO2Cl4]2-in the mixture were measured at 25 ℃ using a Pt working electrode,a Pt wire counter electrode,and an Ag/Ag + reference electrode(0.01 M AgNO 3,0.1 M tetrabutylammonium perchlorate in acetonitrile) in a glove box under an Ar atmosphere.Peaks corresponding to one redox couple were observed around-1.05 V(Epc) and-0.92 V(Epa) vs.ferrocene/ferrocenium ion(Fc/Fc +).The potential differences between two peaks(Ep) increased from 101 to 152 mV with an increase in the scan rate from 50 to 300 mV s-1,while the(Epc+Epa)/2 value was constant,-0.989 V vs.Fc/Fc + regardless of the scan rate.Furthermore,the diffusion coefficient of [UO2Cl4]2-and the standard rate constant were estimated to be 3.7 × 10-8 cm 2 s-1 and(2.7-2.8) × 10-4 cm s-1 at 25 oC.By using the diffusion coefficient and the standard rate constant,the simulation of CVs was performed based on the reaction,[UO2Cl4]2-+ e = [UO2Cl4]3-.The simulated CVs were found to be consistent with the experimental ones.From these results,it is concluded that [UO2Cl4]2-in the mixture of EMICl and EMIBF 4 is reduced to [UO2Cl4]3-quasi-reversibly at-0.989 V vs.Fc/Fc +. | OGURA Toshinari SASAKI Kotoe TAKAO Koichiro ARAI Tsuyoshi IKEDA Yasuhisa | 2012 | Science China Chemistry2012，55，9： | 6 |
| 17 | 有为决定早阶段的区分的胃的癌的扩展区域的 NBI 的在我的 DL 的实用性显示文摘 AIM: To investigate whether magnifying endoscopy with narrow band imaging (ME-NBI) is useful for evaluating the area of superficial, depressed- or flat-type differentiated adenocarcinoma of the stomach. METHODS: This procedure was performed in Saitama Medical University International Medical Center, Japanese Red Cross Kumamoto Hospital and Kitakyushu Municipal Medical Center. The subjects were 31 patients in whom biopsy findings, from superficial, depressed- or flat-type gastric lesion, suggested differentiated adenocarcinoma in the above 3 hospitals between January and December 2009. Biopsy was performed on the lesion and non-lesion sides of a boundary (imaginary boundary) visualized on ME-NBI. The results were pathologically investigated. We evaluated the accuracy of estimating a demarcation line (DL) on ME-NBI in comparison with biopsy findings as a gold standard. RESULTS: The DL that could be recognized at 2 points on the orifice and anal sides of each lesion during ME-NBI was consistent with the pathological findings in 22 patients with 0-Ⅱc lesions, 7 with 0-Ⅱb lesions, and 2 with 0-Ⅱb + Ⅱc lesions, showing an accuracy of 100%. CONCLUSION: The results suggest the usefulness of ME-NBI for evaluating the area of superficial, depressed- and flat-type differentiated adenocarcinoma of the stomach. | Kouichi Nonaka Masaaki Namoto Hideki Kitada Michio Shimizu Yasutoshi Ochiai Osamu Togawa Masamitsu Nakao Makoto Nishimura Keiko Ishikawa Shin Arai Hiroto Kita | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，8： | 6 |
| 18 | In vitro and in vivo antioxidative and hepatoprotective activity of aqueous extract of Cortex Dictamni显示文摘AIM To investigate the antioxidant and hepatoprotective effects of Cortex Dictamni aqueous extract(CDAE) in carbon tetrachloride(CCl4)-induced liver damage in rats.METHODS The in vitro antioxidant effect of CDAE was investigated using α,α-diphenyl-β-picrylhydrazyl(DPPH), 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid)(ABTS), β-carotene bleaching, reducing power, and thiobarbituric acid reactive substance assays. A linoleic acid system, including ferric thiocyanate(FTC) and thiobarbituric acid(TBA) assays, was used to evaluate the inhibition of lipid peroxidation. The in vivo hepatoprotective and antioxidant effects of CDAEagainst CCl4-induced liver damage were evaluated in Sprague-Dawley rats. Silymarin was used as a positive control. Liver damage was assessed by determining hepatic histopathology and liver marker enzymes in serum. Enzyme and non-enzyme antioxidant levels and lipid peroxide content were measured in the liver. Cytochrome P450 2E1(CYP2E1) protein expression was measured via immunohistochemical staining. Nuclear factor E2-related factor(Nrf2), heme oxygenase-1(HO-1), NAD(P)H quinine oxidoreductase 1(NQO1), and γ-glutamylcysteine synthetase catalytic subunit(γ-GCSc) protein expression was measured by Western blot.RESULTS Our results showed that CDAE exhibited a strong antioxidant activity in vitro. CDAE scavenged DPPH and ABTS radicals in a dose-dependent manner. CDAE inhibited lipid peroxidation with a lipid peroxide inhibition rate of 40.6% ± 5.2%. In the FTC and TBA assays, CDAE significantly inhibited lipid peroxidation(P < 0.01). In vivo histopathological studies indicated that CCl4-induced liver injury was alleviated following CDAE treatment in rats of both sexes. CDAE(160 and 320 mg/kg) significantly prevented CCl4-induced elevations of alkaline phosphatase, glutamate pyruvate transaminase, aspartate aminotransferase, and total bilirubin levels in rats of both sexes(P < 0.05, 0.01, or 0.001). Moreover, CDAE restored the decreased activities of hepatic antioxidant enzymes, including superoxide dismutase, catalase, and glutathione peroxidase, as well as non-enzyme antioxidant glutathione, which were induced by CCl4 treatment. CDAE significantly suppressed the up-regulation of CYP2E1 and promoted Nrf2, HO-1, NQO1, and γ-GCSc protein expression.CONCLUSION CDAE exhibits good antioxidant performance in vitro, with marked radical-scavenging and anti-lipid peroxidation activities. CDAE is effective in preventing CCl4-induced hepatic damage in rats of both sexes. The hepatoprotective activity of CDAE may be attributable to its antioxidant activity, which may involve Keap1-Nrf2-mediated antioxidant regulation. | Lin Li Yun-Feng Zhou Yan-Lin Li Li-Li Wang Hiderori Arai Yang Xu | 2017 | World Journal of Gastroenterology2017，23，16： | 6 |

| 20 | Sofosbuvir treatment and hepatitis C virus infection显示文摘Hepatitis C virus(HCV) infection is a serious problem worldwide.The use of interferon-based therapy has made HCV eradication challenging.The recent appearance of direct-acting antiviral agents(DAAs) has changed HCV therapy.Combining the use of DAAs with peginterferon and ribavirin has improved treatment efficacy.Furthermore,the combination of different orally administered DAAs has enabled interferon-free therapy with much higher efficacy and safety.In particular,sofosbuvir,a nucleotide-based NS5 B inhibitor,prevents HCV RNA synthesis by acting as a 'chain terminator'.Treatment with sofosbuvir has attained an extremely high rate of sustained virologic response.The current review summarizes the efficacy and safety of sofosbuvir therapy. | Masato Nakamura Tatsuo Kanda Yuki Haga Reina Sasaki Shuang Wu Shingo Nakamoto Shin Yasui Makoto Arai Fumio Imazeki Osamu Yokosuka | 2016 | World Journal of Hepatology2016，8，3： | 4 |
