3为用离合器切割器的食道的小粒的房间肿瘤的内视镜的 submucosal 解剖显示文摘 Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate.The shortcomings of this method are the deficiencies of fixing the knife to the target lesion,and of compressing it.These shortcomings can lead to major complications such as perforation and bleeding.To reduce the risk of complications related to ESD,we developed a new grasping type scissors forceps (Clutch Cutter,Fujifilm,Japan) which can grasp and incise the targeted tissue using an electrosurgical current.Esophagogastroduodenoscopy on a 59-year-old Japanese man revealed a 16mm esophageal submucosal nodule with central depression.Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement.The histologic diagnosis of the specimen obtained by biopsy was granular cell tumor.It was safely and accurately resected without unexpected incision by ESD using the CC.No delayed hemorrhage or perforation occurred.Histological examination confirmed that the granular cell tumor was completely excised with negative resection margin.We report herein a case of esophageal granular cell tumor successfully treated by an ESD technique using the CC.Keishi Komori Kazuya Akahoshi Yoshimasa Tanaka Yasuaki Motomura Masaru Kubokawa Soichi Itaba Terumasa Hisano Takashi Osoegawa Naotaka Nakama Risa Iwao Masafumi Oya Kazuhiko Nakamura 2012World Journal of Gastrointestinal Endoscopy2012,4,1:8
4Role of RANKL/RANK in primary and secondary breast cancer显示文摘Bone is one of the most preferential metastatic target sites of breast cancer. Bone possesses unique biological microenvironments in which various growth factors are stored and continuously released through osteoclastic bone resorption, providing fertile soil for circulating breast cancer cells. Bone-disseminated breast cancer cells in turn produce osteotropic cytokines which modulate bone environments. Under the influences of breast cancer-produced cytokines, osteoblasts express elevated levels of Ligand for receptor activator of nuclear factor-κB(RANKL) and stimulate osteoclastogenesis via binding to the receptor receptor activator of nuclear factor-κB(RANK) and activating its downstream signaling pathways in hematopoietic osteoclast precursors, which causes further osteoclastic bone destruction. Establishment of crosstalk with bone microenvironments(so called vicious cycle) is an essential event for metastatic breast cancer cells to develop bone metastasis. RANKL and RANK play a central role in this crosstalk. Moreover, recent studies have demonstrated that RANKL and RANK are involved in tumorigenesis and distant metastasis independent of bone microenvironments. Pharmacological disruption of the RANKL/RANK interplay should be an effective therapeutic intervention for primary breast tumors and bone and non-bone metastasis. In this context, denosumab, which is neutralizing monoclonal antibody against RANKL, is a mechanismbased drug for the treatment of bone metastases and would be beneficial for breast cancer patients with bone metastases and potentially visceral organ metastases.Toshiyuki Yoneda Soichi Tanaka Kenji Hata 2013World Journal of Orthopedics2013,4,4:5
5Effects on coagulation factor production following primary hepatomitogen-induced direct hyperplasia显示文摘AIM:To investigate the molecular mechanisms involved in coagulation factor expression and/or function during direct hyperplasia(DH) -mediated liver regeneration.METHODS:Direct hyperplasia-mediated liver regeneration was induced in female C57BL/6 mice by administering 1,4-bis[2-(3,5-dichloropyridyloxy) ] benzene(TCPOBOP) ,a representative hepatomitogen.Mice were weighed and sacrificed at various time points [Day 0(D0:prior to injection) ,3 h,D1,D2,D3,and D10] after TCPOBOP administration to obtain liver and blood samples.Using the RNA samples extracted from the liver,a comprehensive analysis was performed on the hepatic gene expression profiling of coagulation-related factors by real-time RT-PCR(fibrinogen,prothrombin,factors Ⅴ,Ⅶ,Ⅷ,Ⅸ,Ⅹ,Ⅺ,Ⅻ,XⅢβ,plasminogen,antithrombin,protein C,protein S,ADAMTS13,and VWF) .The corresponding plasma levels of coagulation factors(fibrinogen,prothrombin,factors Ⅴ,Ⅶ,Ⅷ,Ⅸ,Ⅹ,Ⅺ,Ⅻ,XⅢ,and VWF) were also analyzed and compared with their mRNA levels.RESULTS:Gavage administration of TCPOBOP(3 mg/kg body weight) resulted in a marked and gradual increase in the weight of the mouse livers relative to the total body weight to 220% by D10 relative to the D0(control) ratios.At the peak of liver regeneration(D1 and D2) ,the gene expression levels for most of the coagulationrelated factors(fibrinogen,prothrombin,factors Ⅴ,Ⅶ,Ⅷ,Ⅸ,Ⅺ,Ⅻ,XⅢβ,plasminogen,antithrombin,protein C,ADAMTS13,VWF) were found to be downregulated in a time-dependent manner,and gradually recovered by D10 to the basal levels.Only mRNA levels of factor Ⅹ and protein S failed to show any decrease during the regenerative phase.As for the plasma levels,5 clotting factors(prothrombin,factors Ⅷ,Ⅸ,Ⅺ,and Ⅻ) demonstrated a significant decrease(P < 0.05) during the regeneration phase compared with D0.Among these 5 factors,factor Ⅸ and factor Ⅺ showed the most dramatic decline in their activities by about 50% at D2 compared to the basal levels,and these reductions in plasma activity for both factors were consistent with our RT-PCR findings.In contrast,the plasma activities of the other coagulation factors(fibrinogen,factors Ⅴ,Ⅶ,XⅢ,and VWF) were not significantly reduced,despite the reduction in the liver mRNA levels.Unlike the other factors,FX showed a temporal increase in its plasma activity,with significant increases(P < 0.05) detected at D1.CONCLUSION:Investigating the coagulation cascade protein profiles during liver regeneration by DH may help to better understand the basic biology of the liver under normal and pathological conditions.Kohei Tatsumi Kazuo Ohashi Sanae Taminishi Soichi Takagi Rie Utoh Akira Yoshioka Midori Shima Teruo Okano 2009World Journal of Gastroenterology2009,15,42:5

7Dual therapy with zinc acetate and rifaximin prevents from ethanolinduced liver fibrosis by maintaining intestinal barrier integrity显示文摘BACKGROUND Hepatic overload of gut-derived lipopolysaccharide dictates the progression of alcoholic liver disease(ALD)by inducing oxidative stress and activating Kupffer cells and hepatic stellate cells through toll-like receptor 4 signaling.Therefore,targeting the maintenance of intestinal barrier integrity has attracted attention for the treatment of ALD.Zinc acetate and rifaximin,which is a nonabsorbable antibiotic,had been clinically used for patients with cirrhosis,particularly those with hepatic encephalopathy,and had been known to improve intestinal barrier dysfunction.However,only few studies focused on their efficacies in preventing the ALD-related fibrosis development.AIM To investigate the effects of a combined zinc acetate with rifaximin on liver fibrosis in a mouse ALD model.METHODS To induce ALD-related liver fibrosis,female C57BL/6J mice were fed a 2.5%(v/v)ethanol-containing Lieber-DeCarli liquid diet and received intraperitoneal carbon tetrachloride(CCl4)injection twice weekly(1 mL/kg)for 8 wk.Zinc acetate(100 mg/L)and/or rifaximin(100 mg/L)were orally administered during experimental period.Hepatic steatosis,inflammation and fibrosis as well as intestinal barrier function were evaluated by histological and molecular analyses.Moreover,the direct effects of both agents on Caco-2 barrier function were assessed by in vitro assays.RESULTSIn the ethanol plus CCl4-treated mice,combination of zinc acetate and rifaximin attenuated oxidative lipid peroxidation with downregulation of Nox2 and Nox4.This combination significantly inhibited the Kupffer cells expansion and the proinflammatory response with blunted hepatic exposure of lipopolysaccharide and the toll-like receptor 4/nuclear factor kB pathway.Consequently,liver fibrosis and hepatic stellate cells activation were efficiently suppressed with downregulation of Mmp-2,-9,-13,and Timp1.Both agents improved the atrophic changes and permeability in the ileum,with restoration of tight junction proteins(TJPs)by decreasing the expressions of tumor necrosis factorαand myosin light chain kinase.In the in vitro assay,both agents directly reinforced ethanol or lipopolysaccharide-stimulated paracellular permeability and upregulated TJPs in Caco-2 cells.CONCLUSION Dual therapy with zinc acetate and rifaximin may serve as a strategy to prevent ALD-related fibrosis by maintaining intestinal barrier integrity.Yuki Fujimoto Kosuke Kaji Norihisa Nishimura Masahide Enomoto Koji Murata Soichi Takeda Hiroaki Takaya Hideto Kawaratani Kei Moriya Tadashi Namisaki Takemi Akahane Hitoshi Yoshiji 2021World Journal of Gastroenterology2021,27,48:4
8A unique case of collagenous colitis presenting as protein-losing enteropathy successfully treated with prednisolone显示文摘A 76-year-old woman with a 5-mo history of recurrent diarrhea and generalized edema was admitted to our hospital. Colonoscopy revealed edematous mucosa,and histopathological examination was compatible with collagenous colitis. Protein leakage from the colon,particularly in the ascending portion,was identified on 99mTc-human serum albumin scintigraphy. Collagenous colitis associated with protein-losing enteropathy (PLE) without small bowel disease was diagnosed. Prednisolone treatment ameliorated diarrhea and hypoproteinemia. Collagenous colitis should be included in the differential diagnosis of chronic diarrhea with hypoproteinemia for appropriate management.Soichi Sano Keiko Yamagami Ayako Tanaka Minako Nishio Tomoyuki Nakamura Yuki Kubo Takeshi Inoue Wataru Ueda Kiyotaka Okawa Katsunobu Yoshioka 2008World Journal of Gastroenterology2008,14,39:3

10Hilar cholangiocarcinoma with intratumoral calcification: A case report显示文摘This report describes a rare case of hilar cholangiocarcinoma with intratumoral calcification that mimicked hepatolithiasis. A 73-year-old man presented to a local hospital with a calcified lesion in the hepatic hilum. At first,hepatolithiasis was diagnosed,and he underwent endoscopic stone extraction via the transpapillary route. This treatment strategy failed due to biliary stricture. He was referred to our hospital,and further examination suggested the existence of cholangiocarcinoma. He underwent left hepatectomy with caudate lobectomy and extrahepatic bile duct resection. Pathological examination revealed hilar cholangiocarcinoma with intratumoral calcification,while no stones were found. To the best of our knowledge,only one case of calcified hilar cholangiocarcinoma has been previously reported in the literature. Here,we report a rare case of calcified hilar cholangiocarcinoma and reveal its clinicopathologic features.Kazuho Inoko Takahiro Tsuchikawa Takehiro Noji Yo Kurashima Yuma Ebihara Eiji Tamoto Toru Nakamura Soichi Murakami Keisuke Okamura Toshiaki Shichinohe Satoshi Hirano 2015World Journal of Gastroenterology2015,21,38:2

13Endoscopic mucosal resection vs endoscopic submucosal dissection for superficial non-ampullary duodenal tumors显示文摘BACKGROUND The selection of endoscopic treatments for superficial non-ampullary duodenal epithelial tumors(SNADETs)is controversial.AIM To compare the efficacy and safety of endoscopic mucosal resection(EMR)and endoscopic submucosal dissection(ESD)for SNADETs.METHODS We retrospectively analyzed the data of patients with SNADETs from a database of endoscopic treatment for SNADETs,which included eight hospitals in Fukuoka,Japan,between April 2001 and October 2017.A total of 142 patients with SNADETs treated with EMR or ESD were analyzed.Propensity score matching was performed to adjust for the differences in the patient characteristics between the two groups.We analyzed the treatment outcomes,including the rates of en bloc/complete resection,procedure time,adverse event rate,hospital stay,and local or metastatic recurrence.RESULTS Twenty-eight pairs of patients were created.The characteristics of patients between the two groups were similar after matching.The EMR group had a significantly shorter procedure time and hospital stay than those of the ESD group[median procedure time(interquartile range):6(3-10.75)min vs 87.5(68.5-136.5)min,P<0.001,hospital stay:8(6-10.75)d vs 11(8.25-14.75)d,P=0.006].Other outcomes were not significantly different between the two groups(en bloc resection rate:82.1%vs 92.9%,P=0.42;complete resection rate:71.4%vs 89.3%,P=0.18;and adverse event rate:3.6%vs 17.9%,P=0.19,local recurrence rate:3.6%vs 0%,P=1;metastatic recurrence rate:0%in both).Only one patient in the ESD group underwent emergency surgery owing to intraoperative perforation.CONCLUSION EMR has significantly shorter procedure time and hospital stay than ESD,and provides acceptable curability and safety compared to ESD.Accordingly,EMR for SNADETs is associated with lower medical costs.Mitsuru Esaki Kazuhiro Haraguchi Kazuya Akahoshi Naru Tomoeda Akira Aso Soichi Itaba Haruei Ogino Yusuke Kitagawa Hiroyuki Fujii Kazuhiko Nakamura Masaru Kubokawa Naohiko Harada Yosuke Minoda Sho Suzuki Eikichi Ihara Yoshihiro Ogawa 2020World Journal of Gastrointestinal Oncology2020,12,8:2
14Influence of Separated Vortex on Aerodynamic Noise of an Airfoil Blade显示文摘In order to clarify the mechanism by which aerodynamic noise is generated from separated flow around an airfoil blade,the relation between the attack angle and the aerodynamic noise of the blade was analyzed using a wind tunnel experiment and a CFD code.In the case of rear surface separation,the separated vortex which has a large-scale structure in the direction of the blade chord is transformed into a structure that concentrates at the trailing edge with an increase in the attack angle.The aerodynamic noise level then becomes small according to the vortex scale in the blade chord.When the flow is separated at the leading edge,a separated vortex of low pressure is formed at the vicinity of the trailing edge.The pressure fluctuations on the blade surface at the vicinity of the trailing edge become large due to the vortex in the wake.It is considered that the aerodynamic noise level increases when the flow is separated at the leading edge because the separated vortex is causing the fluctuations due to wake vortex shedding.Soichi Sasaki Hajime Takamatsu Masao Tsujino Haruhiro Tsubota Hidechito Hayashi 2010Journal of Thermal Science2010,19,1:2
15Improved method of plasma 8-Isoprostane measurement and association analyses with habitual drinking and smoking显示文摘AIM: To develop a simple and accurate method for quantifying 8-isoprostane in plasma by employing a combination of two-step solid-phase extraction of samples and a commercially available ELISA kit, and by this method to examine the effects of drinking and smoking habits against the levels of plasma 8-isoprostane in healthy Japanese volunteers.METHODS: Plasma 8-isoprostane was extracted with ODS gel suspension followed by NH2 Sep-Pak column. The 8-isoprostane fractions were assayed using a commercially available ELISA kit. We measured plasma 8-isoprostane levels in 157 healthy Japanese volunteers divided into three groups (64 non-habitual drinkers, 56 moderate drinkers and 37 habitual drinkers) according to their alcohol consumption per week. Genotypes of aldehyde dehydrogenase 2 (ALDH2) were also determined to investigate the plasma 8-isoprostane levels with reference to drinking habits. In addition, the plasma 8-isoprostane levels of 96 non-smokers and 61 smokers from the same subjects were compared.RESULTS: Our method fulfilled all the requirements for use in routine clinical assays with respect to sensitivity, intra- and inter-assay reproducibility, accuracy and dynamic assay range. Significant increases of plasma 8-isoprostane levels were observed in female habitual drinkers when compared with those of non-habitual drinkers (t = 5.494, P < 0.0001) as well as moderate drinkers (t = 3.542, P < 0.005), and 8-isoprostane levels were also significantly different between ALDH2*2/1 and ALDH2*1/1 in the female habitual drinkers (t = 6.930, P < 0.0001), suggesting that excessive drinking of alcohol may increase oxidization stress, especially in females. On the contrary, no significant difference of the plasma 8-isoprostane levels was observed between non-smokers and smokers.CONCLUSION: Our present method was proved to be a simple and accurate tool for measuring plasma 8-isoprostane. However, the clinical utility of plasma 8-isoprostane for drinking and smoking habits was limited since elevated 8-isoprostane levels were observed in female heavy drinkers, and no association was found between smokers and nonsmokers.Soichi Kitano Hisashi Hisatomi Nozomu Hibi Katsumi Kawano Shoji Harada 2006World Journal of Gastroenterology2006,12,36:2

17Isolated ileal perforation due to cytomegalovirus reactivation during management of terbinafine hypersensitivity显示文摘We report a case of 71-year-old man who developed a hypersensitivity syndrome associated with terbinafine. He was placed on terbinafine (250 mg/d) for the treatment of tinea pedis due to diabetes mellitus. Following the treatment with terbinafine, he developed druginduced hypersensitivity syndrome (DIHS). Systemic corticosteroid led to transient improvement of his clinical manifestations. Three months after disease onset, he presented with panperitonitis due to ileal perforation, and underwent an emergency operation. The affected ileum was resected and ileostomy was performed in the terminal ileum. Cytomegalovirus (CMV)-specific IgG antibodies were significantly increased, high-titer CMV antigenemia was detected, and pathological examination of the resected ileum confirmed CMV infection. Based onthese observations, we strongly recommend that physicians monitor reactivation of the family of herpesvirus other than herpesvirus 6, to manage DIHS properly.Soichi Sano Hiroki Ueno Keiko Yamagami Yosuke Yakushiji Yoshihiro Isaka Isao Kawasaki Masashi Takemura Takeshi Inoue Masayuki Hosoi 2010World Journal of Gastroenterology2010,16,26:2
