| 1 | Comparative study of esomeprazole and lansoprazole in triple therapy for eradication of Helicobacter pylori in Japan显示文摘AIM:To evaluate the efficacy and safety of esomeprazole-based triple therapy compared with lansoprazole therapy as first-line eradication therapy for patients with Helicobacter pylori(H.pylori)in usual post-marketing use in Japan,where the clarithromycin(CAM)resistance rate is 30%.METHODS:For this multicenter,randomized,openlabel,non-inferiority trial,we recruited patients(≥20years of age)with H.pylori infection from 20 hospitals in Japan.We randomly allocated patients to esomeprazole therapy(esomeprazole 20 mg,CAM 400 mg,amoxicillin(AC)750 mg for the first 7 d,with all drugs given twice daily)or lansoprazole therapy(lansoprazole30 mg,CAM 400 mg,AC 750 mg for the first 7 d,with all drugs given twice daily)using a minimization method with age,sex,and institution as adjustment factors.Our primary outcome was the eradication rate by intention-to-treat(ITT)and per-protocol(PP)analyses.H.pylori eradication was confirmed by a urea breath test from 4 to 8 wk after cessation of therapy.RESULTS:ITT analysis revealed the eradication rates of 69.4%(95%CI:61.2%-76.6%)for esomeprazole therapy and 73.9%(95%CI:65.9%-80.6%)for lansoprazole therapy(P=0.4982).PP analysis showed eradication rate of 76.9%(95%CI:68.6%-83.5%)for esomeprazole therapy and 79.8%(95%CI:71.9%-86.0%)for lansoprazole therapy(P=0.6423).There were no differences in adverse effects between the two therapies.CONCLUSION:Esomeprazole showed non-inferiority and safety in a 7 day-triple therapy for eradication of H.pylori compared with lansoprazole. | Tsutomu Nishida Masahiko Tsujii Hirohisa Tanimura Shusaku Tsutsui Shingo Tsuji Akira Takeda Atsuo Inoue Hiroyuki Fukui Toshiyuki Yoshio Osamu Kishida Hiroyuki Ogawa Masahide Oshita Ichizo Kobayashi Shinichiro Zushi Makoto Ichiba Naoto Uenoyama Yuichi Yasunaga Ryu Ishihara Mamoru Yura Masato Komori Satoshi Egawa Hideki Iijima Tetsuo Takehara | 2014 | World Journal of Gastroenterology2014，20，15： | 13 |
| 2 | 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 |
| 3 | Usefulness of bispectral monitoring of conscious sedation during endoscopic mucosal dissection显示文摘AIM: To assess the usefulness of bispectral index (BIS) monitoring in order to carry out endoscopic submucosal dissection (ESD) safely and with patients' satisfaction. METHODS: Three hundred sixty-six patients with an early-stage neoplasm of the digestive tract were enrolled. The BIS monitor (A-1050: Aspect medical systems/NIHON KOHDEN, Tokyo, Japan) was used. The appropriate sedative condition was set at 55 to 75 BIS levels (BIS value) during the endoscopic procedures. RESULTS: Among 366 cases, 13 were accompanied by adverse events during and/or after ESD. All episodes occurred in cases with BIS value between 56 and 65. Hypotension was observed in four cases, and bradycardia in six. Respiratory distress was observed in two cases with chronic pulmonary obstructive disease. All patients with adverse events were able to leave the hospital without extension of the hospitalization. CONCLUSION: BIS monitoring is useful to safely perform ESD. A BIS value of 70 to 75 is suitable for ESD. | Kazunori Hata Akira Andoh Kiyoyuki Hayafuji Atsuhiro Ogawa Tamio Nakahara Tomoyuki Tsujikawa Yoshihide Fujiyama Yasuharu Saito | 2009 | World Journal of Gastroenterology2009，15，5： | 9 |
| 4 | Modulatory effects of Bifidobacterium longum BB536 on defecation in elderly patients receiving enteral feeding显示文摘AIM:To investigate the effects of the probiotic Bifidobacterium longum BB536 on the health management of elderly patients receiving enteral feeding.METHODS:Two double-blind,placebo-controlled trials were performed with long-term inpatients receiving enteral tube feeding at Kitakyushu Hospital Group,Fukuoka,Japan.BB536 was administered as BB536-L and BB536-H powders that contained approximately 2.5 × 10 10 and 5 × 10 10 cfu of BB536,respectively.In the first trial,83 patients(age range:67-101 years) were randomized into 2 groups that received placebo(placebo group) or BB536-H(BB536 group) powders.In the second trial,123 patients(age range:65-102years) were randomized into 3 groups,and each group received placebo(placebo group),BB536-L(BB536-L group),or BB536-H(BB536-H group) powders.Each patient received the study medication for 16 wk after 1 wk of pre-observation.Fecal samples were collected from each patient prior to and after the intervention during Trial 2.Clinical observations included body temperature,occurrence of infection,frequency of defecation,and fecal microbiota.RESULTS:No significant changes were observed in the frequency of defecation for either treatment in Trial 1.However,a significant change was noted in the BB536-L group(P = 0.0439) in Trial 2 but not in the placebo or BB536-H groups.Subgroup analyses based on the frequency of defecation for each patient during the pre-observation period for both trials revealed significant increases in bowel movements in patients with a low frequency of defecation and significant decreases in the bowel movements of patients with a high frequency of defecation during the intervention period in the BB536 groups.The combination of Trials 1 and 2 data revealed a modulatory effect of BB536 ingestion on the changes in bowel movements.Significantly increased bowel movements were observed in patients in the low frequency subgroup with significant intergroup differences(P < 0.01).Significantly decreased bowel movements were observed in patients in the high subgroup,but no significant intergroup differences were observed compared with the placebo group.BB536 ingestion increased the prevalence of normally formed stools.BB536 intake also significantly(P < 0.01) increased the cell numbers of bifidobacteria in fecal microbiota,and significant intergroup differences were observed at week 16.No adverse events were reported in any group.CONCLUSION:Our results suggest that BB536 ingestion modulated the intestinal environment and may have improved the health care of elderly patients receiving enteral feeding. | Junko Kondo Jin-Zhong Xiao Akira Shirahata Mieko Baba Akie Abe Koichi Ogawa Taeko Shimoda | 2013 | World Journal of Gastroenterology2013，19，14： | 7 |
| 5 | Control of Collection Efficiency for Axial Flow Cyclone Dust Collectors with Fixed Guide Vanes and with Funnel Shaped Exit Pipes显示文摘The experimental result of the collection efficiency of the axial flow cyclone with the fixed guide vanes is lowerthan that with the tangential inlet pipe to the cyclone body due to the weak angular momentum transfer given byflowing through the guide vanes.However,one of the interesting points is the control of the collection efficiencydepended on the funnel shaped exit pipes.The collection efficiencies for these funnel shaped exit pipes aredepended on the Froude number.Then,in this paper,the experimental results of the pressure drop and also thecollection efficiency using the fly-ash particles and also the comparison of the calculated results of the collectionefficiency with the experimental results are described in detail. | Akira Ogawa Masaru Arakawa | 2006 | Journal of Thermal Science2006，15，3： | 4 |
| 6 | Survival of geriatric patients after percutaneous endoscopic gastrostomy in Japan显示文摘AIM: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan. METHODS: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient’s characteristics at PEG using log-rank tests and Cox proportional hazard models. RESULTS: Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors. CONCLUSION: These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors. | Yutaka Suzuki Seryna Tamez Akihiko Murakami Akihiko Taira Akihiro Mizuhara Akira Horiuchi Chie Mihara Eiji Ako Hirohito Muramatsu Hitoshi Okano Hitoshi Suenaga Kazuaki Jomoto Junya Kobayashi Katsunari Takifuji Kazuhiro Akiyama Koh Tahara Koji Onishi Makoto Shimazaki Masami Matsumoto Masashi Ijima Masato Murakami Masato Nakahori Michiaki Kudo Michio Maruyama Mikako Takahashi Naohiro Washizawa Shigeru Onozawa Satoshi Goshi Satoyoshi Yamashita Shigeki Ono Shin Imazato Shinji Nishiwaki Shuichirou Kitahara Takao Endo Takao Iiri Takeshi Nagahama Takuto Hikichi Tatsuya Mikami Tetsuo Yamamoto Tetsushi Ogawa Tomoko Ogawa Tomoyuki Ohta Toshifumi Matsumoto Toshiroh Kura Tsutomu Kikuchi Tsuyoshi Iwase Tsuyotoshi Tsuji Yukio Nishiguchi Mitsuyoshi Urashima | 2010 | World Journal of Gastroenterology2010，16，40： | 4 |

| 8 | Effect of double platinum agents, combination of miriplatintransarterial oily chemoembolization and cisplatinhepatic arterial infusion chemotherapy, in patients with hepatocellular carcinoma: Report of two cases显示文摘Hepatocellular carcinoma(HCC) is one of the most common cancers and the third highest cause of cancerassociated mortality worldwide. The treatment of HCC is complicated by its variable biological behavior and the frequent coexistence of chronic liver disease, particularly cirrhosis. To date, multiple treatment modalities have been developed according to the stage of the tumor and the hepatic functional reserve, including transarterial treatments such as transarterial chemoembolization, transarterial oily chemoembolization(TOCE), and hepatic arterial infusion chemotherapy(HAIC). We conducted a phase I and II study of the combination therapy with double platinum agents, miriplatin and cisplatin, and confirmed its safety and efficacy. Here, we describe two cases of unresectable HCC who were successfully treated by miriplatin-TOCE/cisplatin-HAIC combination therapy, resulting in complete responses with no significant adverse events. This report will provide that the combination therapy can be the therapeutic option for HCC patients in the advanced stage. | Kohei Ogawa Kenya Kamimura Yukari Watanabe Yosuke Motai Daisuke Kumaki Ryoya Seki Akira Sakamaki Satoshi Abe Hirokazu Kawai Takeshi Suda Satoshi Yamagiwa Shuji Terai | 2017 | World Journal of Clinical Cases2017，5，6： | 4 |
| 9 | On the Pressure Drop and the Velocity Distribution in the Cylindrical Vortex Chamber with Two Inlet Pipes for the Control of Vortex Flow显示文摘Vortex flow is applied to a cyclone dust collector, a vortex combustion chamber, and a vortex diode for vortex control. In order to apply the vortex flow to the industries, it is necessary to keep the stable flow condition and to estimate the response time of the transient flow process and also the intensity of the vortex flow. For control vortex flow, two types of vortex chamber with two inlet pipes were designed. One of them is to promote the vortex flow named as Co-Rotating Flow System and another one is to hinder the vortex flow named as Counter-Rotating Flow System. The pressure drops and the velocity distributions were measured for these vortex chambers. The estimation of the tangential velocity by the application of the angular momentum flux is compared with the measured velocity by a cylindrical Pitot-tube. The characteristics of the total pressure drop could be explained by introducing the circulation. | Akira OGAWA Tutomu OONO Hayato OKABE Noriaki AKIBA Taketo OOYAGI | 2005 | Journal of Thermal Science2005，14，2： | 3 |

| 13 | Diagnosis and management of fibromuscular dysplasia and segmental arterial mediolysis in gastroenterology field: A mini-review显示文摘The vascular diseases including aneurysm, occlusion, and thromboses in the mesenteric lesions could cause severe symptoms and appropriate diagnosis and treatment are essential for managing patients. With the development and improvement of imaging modalities, diagnostic frequency of these vascular diseases in abdominal lesions is increasing even with the small changes in the vasculatures. Among various vascular diseases, fibromuscular dysplasia(FMD) and segmental arterial mediolysis(SAM) are noninflammatory, nonatherosclerotic arterial diseases which need to be diagnosed urgently because these diseases could affect various organs and be lethal if the appropriate management is not provided. However, because FMD and SAM are rare, the cause, prevalence, clinical characteristics including the symptoms, findings in the imaging studies, pathological findings, management, and prognoses have not been systematically summarized. Therefore, there have been neither standard diagnostic criteria nor therapeutic methodologies established, to date. To systematically summarize the information and to compare these disease entities, we have summarized the characteristics of FMD and SAM in the gastroenterological regions by reviewing the cases reported thus far. The information summarized will be helpful for physicians treating these patients in an emergency care unit and for the differential diagnosis of other diseases showing severe abdominal pain. | Masayoshi Ko Kenya Kamimura Kohei Ogawa Kentaro Tominaga Akira Sakamaki Hiroteru Kamimura Satoshi Abe Kenichi Mizuno Shuji Terai | 2018 | World Journal of Gastroenterology2018，24，32： | 2 |
| 14 | Spin-up and Spin-Down Times of Rotational Air Flow Depended on Mean Air Velocity and Surface Roughness on Inner Surface in Cylindrical Vortex Chamber显示文摘The spin-up time TA in the spin-up process and spin-down time TD in the spin-down process of rotational air flow in the cylindrical vortex chamber with three kinds of the artificial surface roughness were investigated. One of the most different characteristics between the smooth and rough surface conditions was the spin-down time TD. Also the transient response of the tangential velocity on the spin-up process was analyzed numerically and this result was compared with the experimental results. The above stated results are reported here in detail. | Akira Ogawa Hiroyuki Murakami | 2004 | Journal of Thermal Science2004，13，1： | 2 |
