| 1 | 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 |
| 2 | Clinical outcomes of ampullary neoplasms in resected margin positive or uncertain cases after endoscopic papillectomy显示文摘BACKGROUND Endoscopic papillectomy(EP) for benign ampullary neoplasms could be a lessinvasive alternative to pancreatoduodenectomy(PD). There are some problems and limitations with EP. The post-EP resection margins of ampullary tumors are often positive or uncertain because of the burning effect of EP. The clinical outcomes of resected margin positive or uncertain cases after EP remain unknown.AIM To investigate the clinical outcomes of resected margin positive or uncertain cases after EP.METHODS Between January 2007 and October 2018, all patients with ampullary tumors who underwent EP at Kobe University Hospital were included in this study. The indications for EP were as follows: adenoma, as determined by preoperative endoscopic biopsy, without bile/pancreatic duct extension, according to endoscopic ultrasound or intraductal ultrasound. The clinical outcomes of resected margin positive or uncertain cases after EP were retrospectively investigated.RESULTS Of the 45 patients, 29 were male, and 16 were female. The mean age of the patients was 65 years old. Forty-one patients(89.5%) underwent en bloc resection,and 4 patients(10.5%) underwent piecemeal resection. After EP, 33 tumors were histopathologically diagnosed as adenoma, and 12 were diagnosed as adenocarcinoma. The resected margins were positive or uncertain in 24 patients(53.3%). Of these cases, 15 and 9 were diagnosed as adenoma and adenocarcinoma, respectively. Follow-up observation was selected for all adenomas and 5 adenocarcinomas. In the remaining 4 adenocarcinoma cases,additional PD was performed. Additional PD was performed in 4 cases, and residual carcinoma was found after the additional PD in 1 of these cases. In the follow-up period, local tumor recurrence was detected in 3 cases. Two of these cases involved primary EP-diagnosed adenoma. The recurrent tumors were also adenomas detected by biopsy. The remaining case involved primary EPdiagnosed adenocarcinoma. The recurrent tumor was also an adenocarcinoma.All of the recurrent tumors were successfully treated with argon plasma coagulation(APC). There was no local or lymph node recurrence after the APC.The post-APC follow-up periods lasted for 57.1 to 133.8 mo. No ampullary tumor-related deaths occurred in all patients.CONCLUSION Resected margin positive or uncertain cases after EP could be managed by endoscopic treatment including APC, even in cases of adenocarcinoma. EP could become an effective less-invasive first-line treatment for early stage ampullary tumors. | Arata Sakai Masahiro Tsujimae Atsuhiro Masuda Takao Iemoto Shigeto Ashina Kohei Yamakawa Takeshi Tanaka Shunta Tanaka Yasutaka Yamada Ryota Nakano Yu Sato Manabu Kurosawa Takuya Ikegawa Seiji Fujigaki Takashi Kobayashi Hideyuki Shiomi Yoshifumi Arisaka Tomoo Itoh Yuzo Kodama | 2019 | World Journal of Gastroenterology2019，25，11： | 9 |
| 3 | Targeting hyaluronan for the treatment of pancreatic ductal adenocarcinoma显示文摘Progression of cancer is often associated with interactions between cancer cells and extracellular matrix(ECM) surrounding them. Increasing evidence has suggested that accumulation of hyaluronan(HA), a major component of ECM, provides a favorable microenvironment for cancer progression. Pancreatic ductal adenocarcinoma(PDAC) is characterized typically by a dense desmoplastic stroma with a large amount of HA, making this molecule as an attractive target for therapy. Several studies have shown efficacy of inhibitors of HA synthesis or signaling for the treatment of PDAC. Recent studies have also demonstrated substantial improvements in the effects of chemotherapy by a targeted depletion of stromal HA in PDAC using an enzymatic agent. Thus, targeting HA has been recognized as a promising therapeutic strategy to treat this highly aggressive neoplasm. In this review article, we summarize our current understanding of the role of HA in the progression of PDAC and discuss possible therapeutic approaches targeting HA. | Norihiro Sato Xiao-Bo Cheng Shiro Kohi Atsuhiro Koga Keiji Hirata | 2016 | Acta Pharmaceutica Sinica B2016，6，2： | 5 |
| 4 | Factors associated with residual gastroesophageal reflux disease symptoms in patients receiving proton pump inhibitor maintenance therapy显示文摘AIM To elucidate the factors associated with residual gastroesophageal reflux disease(GERD) symptoms in patients receiving proton pump inhibitor(PPI) maintenance therapy in clinical practice.METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD(FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale(GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed.RESULTS The FSSG scores ranged from 1 to 28 points(median score: 7.5 points), and 19 patients(48.7%) had a score of 8 points or more. The patients' GSRS scores were significantly correlated with their FSSG scores(correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers(RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers(total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients(total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms. | Fumiaki Kawara Tsuyoshi Fujita Yoshinori Morita Atsushi Uda Atsuhiro Masuda Masaya Saito Makoto Ooi Tsukasa Ishida Yasuyuki Kondo Shiei Yoshida Tatsuya Okuno Yoshihiko Yano Masaru Yoshida Hiromu Kutsumi Takanobu Hayakumo Kazuhiko Yamashita Takeshi Hirano Midori Hirai Takeshi Azuma | 2017 | World Journal of Gastroenterology2017，23，11： | 5 |
| 5 | Phosphorylation of alphaB-crystallin in epiretinal membrane of human proliferative diabetic retinopathy显示文摘AIM: To examine phosphorylation of alpha B-crystallin(p-αBC), a vascular endothelial growth factor(VEGF)chaperone, and immunohistochemically investigate relationship between p-αBC, VEGF and phosphorylated p38-mitogen-activated protein kinase(p-p38 MAPK) in the epiretinal membrane of human proliferative diabetic retinopathy(PDR).METHODS: Eleven epiretinal membranes of PDR surgically excised were included in this study. Two normal retinas were also collected from enucleation tissues due to choroidal melanoma. Paraformaldehyde-fixed, paraffin-embedded tissue sections were processed for immunohistochemistry with anti-p-αBC, VEGF, CD31,and p-p38 MAPK antibodies.RESULTS: Immunoreactivity for p-αBC was observed in all of the epiretinal membranes examined, where phosphorylation on serine(Ser) 59 showed strongest immunoreactivity in over 70% of the membranes. The immunolocalization of p-αBC was detected in the CD31-positive endothelial cells, and co-localized with VEGF and p-p38 MAPK in PDR membranes. Immunoreactivity for p-αBC, however, was undetectable in endothelial cells of the normal retinas, where p-p38 MAPK immunoreactivity was less marked than PDR membranes.CONCLUSION: Phosphorylation of αBC, in particular,phosphorylation on Ser59 by p-p38 MAPK may play a potential role as a molecular chaperon for VEGF in the pathogenesis of epiretinal membranes in PDR. | Yoko Dong Zhenyu Dong Satoru Kase Ryo Ando Junichi Fukuhara Satoshi Kinoshita Saori Inafuku Yoshiaki Tagawa Erdal Tan Ishizuka Wataru Saito Miyuki Murata Atsuhiro Kanda Kousuke Noda Susumu Ishida | 2016 | International Journal of Ophthalmology(English edition)2016，9，8： | 4 |
| 6 | Risk factors for the recurrence of hepatocellular carcinoma after radiofrequency ablation of hepatocellular carcinoma in patients with hepatitis C显示文摘AIM: To analyze the risk factors of hepatocellular carcinoma (HCC) recurrence after radiofrequency ablation (RFA) treatment with HCV-associated hepatitis. METHODS: Twenty-six patients with HCV-associated HCC who were followed-up for more than 12 mo were selected for this study. Risk factors for distant intrahepatic recurrences of HCC were evaluated for patients in whom complete coagulation was achieved without recurrence in the same subsegment as the primary nodule. Twelve clinical and tumoral factors were examined: Age, gender, nodule diameter, number of primary HCC nodule, Child-Pugh classification, serum platelet, serum albumin, serum AST, post RFA AST, serum ALT, post RFA ALT, post RFA treatment.RESULTS: Distant recurrences of HCC in remnant liver after RFA were observed in 14 cases and in the number of primary HCC nodules (P = 0.047), and the serum platelets (P = 0.030), the clear difference came out by the recurrence group and the non-recurrence group. The cumulative recurrence rates after 1 and 2 years were30.8% and 86.8%, respectively for primary multinodular HCC, and 15.4% and 29.5% respectively, for primary uninodular HCC. In addition the 1-year recurrence rates for patients with serum albumin more than 3.4 g/dL and less than 3.4 g/dL were 23.1% for both, but the 2-years recurrence rates were 89.0% and 23.1%, respectively. The number of primary HCC nodules (relative risk, 6.970; P = 0.016) were found to be a statistically significant predictor for poor distant intrahepatic recurrence by univariate analysis.CONCLUSION: Patients who have multiple HCC nodules, low serum platelets and low serum albumin accompanied by HCV infection, should be carefully followed because of the high incidence of new HCC lesions in the remnant liver, even if coagulation RFA is complete. | Yutaka Yamanaka Katsuya Shiraki Kazumi Miyashita Tomoko Inoue Tomoyuki Kawakita Yumi Yamaguchi Yukiko Saitou Norihiko Yamamoto Takeshi Nakano Atsuhiro Nakatsuka Koichiro Yamakado Kan Takeda | 2005 | World Journal of Gastroenterology2005，11，14： | 4 |
| 7 | Tubulopapillary adenoma of the gallbladder accompanied by bile duct tumor thrombus显示文摘Intraductal papillary mucinous neoplasm of the bile duct(IPNB)is recognized as a precancerous lesion;however,both its pathogenesis and progression remain unclear.We present here a case of IPNB arising from the gallbladder accompanied by bile duct tumor thrombus in a 79-year-old female.The resected specimen revealed a tubulopapillary adenoma with no malignant cells.This case suggests that even in the absence of malignant cells,these tumors can behave as malignant tumors requiring aggressive treatment.Even if no malignant cells are present,intraepithelial neoplasms occurring in the ampullopancreatobiliary tract can behave as malignant tumors. | Kentaroh Yamamoto Fumio Yamamoto Atsuhiro Maeda Hirotsune Igimi Mami Yamamoto Ryosuke Yamaguchi Yuichi Yamashita | 2014 | World Journal of Gastroenterology2014，20，26： | 3 |

| 9 | Roles of the (pro) renin receptor in the kidney显示文摘Prorenin receptor(PRR) is a multi-functioning protein possessing at least four different roles:(1) working as a receptor for renin and prorenin producing angiotensin I from angiotensinogen thus enhancing the tissue reninangiotensin system;(2) inducing intracellular signals when a ligand binds to PRR;(3) participating in the functions of vacuolar proton ATPase; and(4) constituting the Wnt signaling receptor complex.Here,the roles of PRR in kidney physiology and diabetic conditions as well as recent findings regarding a soluble form of PRR are discussed.We also propose the possible mechanism concerning diabetic nephropathy as 'trade-off hypothesis' from a PRR point of view.In brief,under hyperglycemic conditions,injured podocytes degrade degenerated proteins and intracellular organelles which require V-ATPase and PRR for vesicle internal acidification.Sustained hyperglycemia overproduces PRR molecules,which are transported to the transmembrane and bind to increased serum prorenin in the diabetic condition.This enhances tissue renin-angiotensin system and PRR-mediated mitogen-activated protein kinase signals,resulting in increased injurious molecules such as transforming growth factor-β,cyclooxygenase2,interleukin-1β,and tumor necrosis factor-α ending in diabetic nephropathy progression.Although many findings led us to better PRR understanding,future works should elucidate which PRR functions,of the four discussed here,are dominant in each cell and kidney disease context. | Yoichi Oshima Satoshi Morimoto Atsuhiro Ichihara | 2014 | World Journal of Nephrology2014，3，4： | 3 |
| 10 | Lack of evidence for leukocyte maternal microchimerism in primary biliary cirrhosis显示文摘It is reasonable to assume that microchimerism could also be involved in the induction of primary biliary cirrhosis (PBC). However, previous reports investigated only fetus-microchimerism in women patients. Maternal microchimerism has not been investigated until now.The current study aimed to clear either maternal microchimerism was involved in the pathogenesis of PBC or not.METHODS: We used fluorescence in situ hybridization on paraffin-embedded tissue (We called 'Tissue-FiSH'.) to determine whether maternal cells infiltrated in male patients who were diagnosed as having PBC. Tissue-FiSH was performed by using both X and Y specific probes on the biopsy liver sample of 3 male PBC patients.RESULTS: Infiltrating lymphocytes demonstrated both X and Y signals in all 3 male patients.CONCLUSION: Maternal microchimerism dose not play asignificant role in PBC. PBC may not relate to fetus and maternal microchimerism. | Kenichi Nomura Yoshio Sumida Takaharu Yoh Atsuhiro Morita Yosuke Matsumoto SawakoTaji NaohisaYoshida MasahitoMinami YoshitoItoh ShigeoHoriike Keisho Kataoka Masafumi Taniwaki Takeshi Okanoue | 2004 | World Journal of Gastroenterology2004，10，16： | 2 |

| 13 | Possible contribution of(pro)renin receptor to development of gestational diabetes mellitus显示文摘(Pro)renin receptor [(P)RR], a receptor for renin and prorenin, was first cloned in 2002. Since then, the pathophysiological roles of(P)RR have been growing concerns.(P)RR binds renin and prorenin, with two important consequences, nonproteolytic activation of prorenin, leading to the tissue renin-angiotensin system activation and the intracellular signalings. It is now also known to play an important role as vacuolar H+-ATPase associated protein, involving in Wnt signaling, main component of embryonic development. Extracellular domain of full-length(P)RR is cleaved in golgi-complex forming soluble(P)RR [s(P)RR]. The s(P)RR is now possible to be measured in human blood and urine. It is now measured in different pathophysiological states, and recent study showed that elevated plasma s(P)RR levels in the early stage of pregnancies are associated with higher incidence of gestational diabetes mellitus later in the pregnancies. Plasma s(P)RR levels of neonates are known to be higher than that of adults. It was also shown that, increased s(P)RR concentrations in cord blood, associated with a lower small for gestational age birth likelihood. These data suggests the involvement of(P)RR in embryo's growth. In thisreview article, we attempt to figure out the possible pathophysiological roles of the(P)RR in maternal glucose intolerance and embryo's growth, through reviewing previous studies. | Kanako Bokuda Atsuhiro Ichihara | 2014 | World Journal of Diabetes2014，5，6： | 2 |

| 17 | Use of water jet instruments in gastrointestinal endoscopy显示文摘In recent years, water jet instruments have been used in the field of gastrointestinal endoscopy, mainly in two clinical situations: Investigation and treatment under endoscopic view. Injecting water jet into the gastrointestinal lumen is helpful for maintaining a clear endoscopic view, washing away blood or mucous in the lumen or on the surface of the tip of the endoscope. This contributes to reducing time and discomfort of examination. Water jet technology is an alternative method for dissecting soft tissue; this method does not harm the small vessels or cause mechanical or thermal damage. However, its use in clinical settings has been limited to the transmucosal injection of water into the submucosal layer that elevates the mucosa to prepare for endoscopic mucosal resection or endoscopic submucosal dissection, instead of tissue dissection, which may occur because of the continuous water jet. A preclinical study has been conducted using a pulsed water jet system as an alternative method for submucosal dissection by reducing intraoperative water consumption and maintenance of dissection capability. This review introduces recent studies pertaining to using a water jet in gastrointestinal endoscopy and discusses future prospects. | Toru Nakano Chiaki Sato Tadashi Sakurai Takashi Kamei Atsuhiro Nakagawa Noriaki Ohuchi | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，3： | 1 |
