| 1 | 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 |
| 2 | Short-and long-term results of endoscopic ultrasoundguided transmural drainage for pancreatic pseudocysts and walled-off necrosis显示文摘AIM To evaluate the short-and long-term results of endoscopic ultrasound-guided transmural drainage(EUS-GTD) for pancreatic fluid collection(PFC) and identify the predictive factors of treatment outcome for walled-off necrosis(WON) managed by EUS-GTD alone.METHODS We investigated 103 consecutive patients with PFC who underwent EUS-GTD between September 1999 and August 2015. Patients were divided into four groups as follows: WON(n = 40), pancreatic pseudocyst(PPC; n = 11), chronic pseudocyst(n = 33), and others(n = 19). We evaluated the short-and long-term outcomes of the treatment. In cases of WON, multiple logistic regression analyses were performed to identify the predictor variables associated with the treatment success. In addition, PFC recurrence was examined in patients followed up for more than 6 mo and internal stent removal after successful EUS-GTD was confirmed.RESULTS In this study, the total technical success rate was 96.1%. The treatment success rate of WON, PPC, chronic pseudocyst, and others was 57.5%, 90.9%, 91.0%, and 89.5%, respectively. Contrast-enhanced computed tomography using the multivariate logistic regression analysis revealed that the treatment success rate of WON was significantly lower in patients with more than 50% pancreatic parenchymal necrosis(OR = 17.0; 95%CI: 1.9-150.7; P = 0.011) and in patients with more than 150 mm of PFC(OR = 27.9; 95%CI: 3.4-227.7; P = 0.002).The recurrence of PFC in the long term was 13.3%(median observation time, 38.8 mo). Mean amylase level in the cavity was significantly higher in the recurrence group than in the no recurrence group(P = 0.02).CONCLUSION The reduction of WON by EUS-GTD alone was associated with the proportion of necrotic tissue and extent of the cavity. The amylase level in the cavity may be a predictive factor for recurrence of PFC. | Yuto Watanabe Rintaro Mikata Shin Yasui Hiroshi Ohyama Harutoshi Sugiyama Yuji Sakai Toshio Tsuyuguchi Naoya Kato | 2017 | World Journal of Gastroenterology2017，23，39： | 7 |
| 3 | Efficacy of multiple biliary stenting for refractory benign biliary strictures due to chronic calcifying pancreatitis显示文摘AIM To investigate endoscopic therapy efficacy for refractory benign biliary strictures(BBS) with multiple biliary stenting and clarify predictors.METHODS Ten consecutive patients with stones in the pancreatic head and BBS due to chronic pancreatitis who underwent endoscopic therapy were evaluated. Endoscopic insertion of a single stent failed in all patients. We used plastic stents(7F, 8.5F, and 10F) and increased stents at intervals of 2 or 3 mo. Stents were removed approximately 1 year after initial stenting. BBS and common bile duct(CBD) diameter were evaluated using cholangiography. Patients were followed for ≥ 6 mo after therapy, interviewed for cholestasis symptoms, and underwent liver function testing every visit. Patients with complete and incomplete stricture dilations were compared.RESULTS Endoscopic therapy was completed in 8(80%) patients, whereas 2(20%) patients could not continue therapy because of severe acute cholangitis and abdominal abscess, respectively. The mean number of stents was 4.1 ± 1.2. In two(20%) patients, BBS did not improve; thus, a biliary stent was inserted. BBS improved in six(60%) patients. CBD diameter improved more significantly in the complete group than in the incomplete group(6.1 ± 1.8 mm vs 13.7 ± 2.2 mm, respectively, P = 0.010). Stricture length was significantly associated with complete stricture dilation(complete group; 20.5 ± 3.0 mm, incomplete group; 29.0 ± 5.1 mm, P = 0.011). Acute cholangitis did not recur during the mean follow-up period of 20.6 ± 7.3 mo.CONCLUSION Sequential endoscopic insertion of multiple stents is effective for refractory BBS caused by chronic calcifying pancreatitis. BBS length calculation can improve patient selection procedure for therapy. | Hiroshi Ohyama Rintaro Mikata Takeshi Ishihara Yuji Sakai Harutoshi Sugiyama Shin Yasui Toshio Tsuyuguchi | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，1： | 6 |
| 4 | MK-0626,a selective DPP-4 inhibitor,attenuates hepatic steatosis in ob/ob mice显示文摘AIM:To investigate the mechanism and in vivo effects of MK-0626,a dipeptidyl peptidase-4 inhibitor,on hepatic steatosis using ob/ob mice.METHODS:We analyzed obese(ob/ob)8-wk-old male mice that had been randomly divided into two groups of ob/ob mice(n=16 each)and were treated with1.5 or 3 mg/kg MK-0626 and two control groups of untreated ob/ob mice and lean littermates(n=16 each).All mice were fed a normal chow diet with or without MK-0626 for either four or eight weeks.Blood samples were collected,and total hepatectomy was performed.RESULTS:The administration of dietary MK-0626 ameliorated the hepatic lipid accumulation in ob/ob micetreated with 3 mg/kg MK-0626(3 MK),P<0.05,vs untreated ob/ob mice(ob/ob).The MK-0626 treatment reduced the serum alanine aminotransferase levels(both treatment groups,P<0.05 vs ob/ob)and glucoses/insulin levels/calculated HOMA scores(1.5 MK,P<0.05vs ob/ob;3 MK,P<0.01 vs ob/ob)and increased the serum adiponectin levels(3 MK,P<0.05 vs ob/ob)in a dose-dependent manner.The MK-0626 treatment increased the m RNA expression of peroxisome proliferator-activated receptorα/microsomal triglyceride transfer protein(1.5 MK,P<0.05 vs ob/ob;3 MK,P<0.01vs ob/ob)but reduced the sterol regulatory element binding transcription factor-1c/fatty acid synthase/stearoyl-Co A desaturase-1(both treatment groups,P<0.01 vs ob/ob).The MK-0626 treatment increased the activity of AMP-activated protein kinase(AMPK)(both treatment groups,P<0.01 vs ob/ob).CONCLUSION:MK-0626 could attenuate hepatic steatosis through enhancing AMPK activity,inhibiting hepatic lipogenic gene expression,enhancing triglyceride secretion from liver and increasing serum adiponectin levels. | Tatsuya Ohyama Ken Sato Yuichi Yamazaki Hiroaki Hashizume Norio Horiguchi Satoru Kakizaki Masatomo Mori Motoyasu Kusano Masanobu Yamada | 2014 | World Journal of Gastroenterology2014，20，43： | 4 |

| 13 | Combination therapy with daclatasvir and asunaprevir for dialysis patients infected with hepatitis C virus显示文摘The standard antiviral therapy for dialysis patients infected with hepatitis C virus(HCV) is(pegylated) interferon monotherapy, but its efficacy is insufficient. Oral direct-acting antiviral agents(DAAs) have recently been developed for chronic hepatitis C patients. However, some DAAs have contraindications for chronic renal failure(CRF). Daclatasvir and asunaprevir are metabolized largely in the liver and are not contraindicated in CRF. Combination therapy with daclatasvir and asunaprevir was used for 4 dialysis patients infected with genotype 1b HCV. One patient had viral breakthrough, and the 3 others had sustained virological response 12. One patient was admitted for heart failure and percutaneous coronary intervention due to concomitant ischemic disease. Heart failure was unlikely to be caused by the combination therapy, as it was probably due to water overload. The patient continued to receive the combination therapy after the remission of the heart failure. The combination therapy was well tolerated in the other patients. | Ken Sato Yuichi Yamazaki Tatsuya Ohyama Takeshi Kobayashi Norio Horiguchi Satoru Kakizaki Motoyasu Kusano Masanobu Yamada | 2016 | World Journal of Clinical Cases2016，4，3： | 2 |
| 14 | 3D attitude measurement by means of spread spectrum modulated ultrasonic wave显示文摘Local position and attitude measurement methods are necessary for the navigation of autonomous robots and the other applications. In this paper, a 3D attitude measurement method is proposed. This method uses the spread spectrum modulated ultrasonic wave for the measurement of the pseudo-distance of each pathway between transmitter and receiver elements that are arranged in an array. The relative attitude between transmitter and receiver unit could be calculated from the relationship between these pseudo-distances. The use of spread spectrum modulation enables the high accuracy, noise tolerance, and coexistence of multiple transmitter devices by code division multiple access (CDMA) between transmitter and receiver elements. A pair of transmitter and receiver prototype for proposed method was manufactured, and the fundamental performance was examined in experiments. As a result, accuracy of σ=0.78 mm in the pseudo-distance measurement of each pathway between transmitter and receiver elements was confirmed, and about 0.01 rad resolution in the attitude measurement was also confirmed. | Shinji Ohyama Hiroshi Iwasawa Sang Il Ko Junya Takayama | 2007 | 仪器仪表学报2007，28，4： | 2 |
