3Review of the diagnosis and management of gastrointestinal bezoars显示文摘The formation of a bezoar is a relatively infrequentdisorder that affects the gastrointestinal system.Bezoars are mainly classified into four types dependingon the material constituting the indigestible mass of thebezoar phytobezoars, trichobezoars, pharmacobezoars,and lactobezoars. Gastric bezoars often cause ulcerativelesions in the stomach and subsequent bleeding,whereas small intestinal bezoars present with smallbowel obstruction and ileus. A number of articles haveemphasized the usefulness of Coca-Cola? administrationfor the dissolution of phytobezoars. However, persimmonphytobezoars may be resistant to such dissolutiontreatment because of their harder consistency comparedto other types of phytobezoars. Better understanding ofthe etiology and epidemiology of each type of bezoarwill facilitate prompt diagnosis and management.Here we provide an overview of the prevalence, classification,predisposing factors, and manifestations ofbezoars. Diagnosis and management strategies arealso discussed, reviewing mainly our own case series.Recent progress in basic research regarding persimmonphytobezoars is also briefly reviewed.Masaya Iwamuro Hiroyuki Okada Kazuhiro Matsueda Tomoki Inaba Chiaki Kusumoto Atsushi Imagawa Kazuhide Yamamoto 2015World Journal of Gastrointestinal Endoscopy2015,7,4:22

5Minimally invasive surgery for upper gastrointestinal cancer: Our experience and review of the literature显示文摘Minimally invasive surgery(MIS) for upper gastro-intestinal(GI) cancer, characterized by minimal access, has been increasingly performed worldwide. It not only results in better cosmetic outcomes, but also reduces intraoperative blood loss and postoperative pain, leading to faster recovery; however, endoscopically enhanced anatomy and improved hemostasis via positive intracorporeal pressure generated by CO2 insufflation have not contributed to reduction in early postoperative complications or improvement in long-term outcomes. Since 1995, we have been actively using MIS for operable patients with resectable upper GI cancer and have developed stable and robust methodology in conducting totally laparoscopic gastrectomy for advanced gastric cancer and prone thoracoscopic esophagectomy for esophageal cancer using novel technology including da Vinci Surgical System(DVSS). We have recently demonstrated that use of DVSS might reduce postoperative local complications including pancreatic fistula after gastrectomy and recurrent laryngeal nerve palsy after esophagectomy. In this article, we present the current status and future perspectives on MIS for gastric and esophageal cancer based on our experience and a review of the literature.Koichi Suda Masaya Nakauchi Kazuki Inaba Yoshinori Ishida Ichiro Uyama 2016World Journal of Gastroenterology2016,22,19:13
6Surgical treatment of HCC in a patient with lamivudine-resistant hepatitis B cirrhosis with adefovir dipivoxil显示文摘We describe a 77-year-old woman with chronic hepatitis B who became resistant to lamivudine.She was started on adefovir(10 mg daily)while still continuing lamivudine therapy.Four mo later her liver function improved and serum Hepatitis B virus(HBV)-DNA level became undetectable.Three years after the start of additional adefovir treatment,hepatocellular carcinoma (HCC)was detected and the patient underwent a successful hepa-tectomy.Our findings suggest tha-t the addition of adefovir to ongoing lamivudine therapy cannot completely suppress hepatocarcinogenesis,but is useful for improving liver function in patients with lamivudine-resistant HBV-related cirrhosis,allowing HCC surgery.Takashi Akima Masaya Tamano Hidetsugu Yamagishi Keiichi Kubota Takahiro Fujimori Hideyuki Hiraishi 2010World Journal of Hepatology2010,2,8:11
7Endoscopic features and prognoses of mantle cell lymphoma with gastrointestinal involvement显示文摘AIM: To evaluate the endoscopic manifestations and prognoses of gastrointestinal (GI) mantle cell lymphoma (MCL). METHODS: A database search at the Department of Pathology of Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences revealed 57 MCL patients with GI involvement. Clinical records were available for 35 of the 57 patients from 21 institutions, and those 35 patients were enrolled in this study. We summarized the gross types of endoscopic features, event-free survival (EFS), and overall survival (OS) of those patients.RESULTS: Of the 35 patients, GI involvement in the esophagus, stomach, and duodenum was found in 2 (5.7%), 26 (74.3%), and 12 (34.3%) patients, respectively. Twenty-one of the 35 patients underwent colonoscopy; among them, GI involvement in the ileum, cecum, colon, and rectum was found in 10 (47.6%), 3 (14.3%), 12 (57.1%), and 10 (47.6%), respectively. Various lesions, such as superficial, protruded, fold thickening, or ulcerative, were found in the stomach, whereas multiple lymphomatous polyposis (MLP) was dominant from the duodenum to the rectum. Twelve patients were treated with a hyper-CVAD/MA regimen, and they had better OS (3-year rate, 88.3% vs 46.4%, P < 0.01) and better EFS (3-year rate, 66.7% vs 33.8%, P < 0.05) than the remaining 23 patients who were not treated with this regimen. CONCLUSION: MLP was a representative form of intestinal involvement, whereas a variety of lesions were found in the stomach. The hyper-CVAD/MA regimen may improve survival in these patients.Masaya Iwamuro Hiroyuki Okada Yoshiro Kawahara Katsuji Shinagawa Toshiaki Morito Tadashi Yoshino Kazuhide Yamamoto 2010World Journal of Gastroenterology2010,16,37:9
8Efficacy of multislice computed tomography for gastroenteric and hepatic surgeries显示文摘AIM: To determine the efficacy of multislice CT for gastroenteric and hepatic surgery.METHODS: Dual-phase helical computed tomography was performed in 50 of 51 patients who underwent gastroenteric and hepatic surgeries. Twenty-eight, eighteen and four patients suffering from colorectal cancer, gastric cancer,and liver cancer respectively underwent colorectal surgery (laparoscopic surgery: 6 cases), gastrectomy, and hepatectomy. Three-dimensional computed tomography imaging of the inferior mesenteric artery, celiac artery and hepatic artery was performed. And in the follow-up examination of postoperative patients, multiplanar reconstruction image was made in case of need.RESULTS: Scans in 50 patients were technically satisfactory and included in the analysis. Depiction of major visceral arteries, which were important for surgery and other treatments, could be done in all patients.Preoperative visualization of the left colic artery and sigmoidal arteries, the celiac artery and its branches, and hepatic artery was very useful to lymph node dissection,the planning of a reservoir and hepatectomy. And multiplanar reconstruction image was helpful to diagnosis for the postoperative follow-up of patients.CONCLUSION: Three-dimensional volume rendering or multiplanar reconstruction imaging performed by multislice computed tomography was very useful for gastroenteric and hepatic surgeries.Hiroshi Ohtani Hidemi Kawajiri Yuichi Arimoto Koichi Ohno Yasuhisa Fujimoto Hiroko Oba Kenji Adachi Masaya Hirano Shoichi Terakawa Mitsuo Tsubakimoto 2005World Journal of Gastroenterology2005,11,10:9
9Silver Nanowire Electrodes: Conductivity Improvement Without Post-treatment and Application in Capacitive Pressure Sensors显示文摘Transparent electrode based on silver nanowires(Ag NWs) emerges as an outstanding alternative of indium tin oxide film especially for flexible electronics. However, the conductivity of Ag NWs transparent electrode is still dramatically limited by the contact resistance between nanowires at high transmittance. Polyvinylpyrrolidone(PVP) layer adsorbed on the nanowire surface acts as an electrically insulating barrier at wire–wire junctions, and some devastating post-treatment methods are proposed to reduce or eliminate PVP layer, which usually limit the application of the substrates susceptible to heat or pressure and burden the fabrication with high-cost, time-consuming, or inefficient processes. In this work, a simple and rapid pre-treatment washing method was proposed to reduce the thickness of PVP layer from 13.19 to0.96 nm and improve the contact between wires. Ag NW electrodes with sheet resistances of 15.6 and 204 X sq-1have been achieved at transmittances of 90 and 97.5 %, respectively. This method avoided any post-treatments and popularized the application of high-performance Ag NW transparent electrode on more substrates. The improved Ag NWs were successfully employed in a capacitive pressure sensor with high transparency, sensitivity, and reproducibility.Jun Wang Jinting Jiu Teppei Araki Masaya Nogi Tohru Sugahara Shijo Nagao Hirotaka Koga Peng He Katsuaki Suganuma 2015Nano-Micro Letters2015,7,1:9
10Non-robotic minimally invasive gastrectomy as an independent risk factor for postoperative intra-abdominal infectious complications: A single-center, retrospective and propensity score-matched analysis显示文摘BACKGROUND Minimally invasive surgery for gastric cancer(GC) has gained widespread use as a safe curative procedure especially for early GC.AIM To determine risk factors for postoperative complications after minimally invasive gastrectomy for GC.METHODS Between January 2009 and June 2019, 1716 consecutive patients were referred to our division for primary GC. Among them, 1401 patients who were diagnosed with both clinical and pathological Stage Ⅲ or lower GC and underwent robotic gastrectomy(RG) or laparoscopic gastrectomy(LG) were enrolled. Retrospective chart review and multivariate analysis were performed for identifying risk factors for postoperative morbidity.RESULTS Morbidity following minimally invasive gastrectomy was observed in 7.5% of the patients. Multivariate analyses demonstrated that non-robotic minimally invasive surgery, male gender, and an operative time of ≥ 360 min were significant independent risk factors for morbidity. Therefore, morbidity was compared between RG and LG. Accordingly, propensity-matched cohort analysis revealed that the RG group had significantly fewer intra-abdominal infectious complications than the LG group(2.5% vs 5.9%, respectively;P = 0.038), while no significant differences were noted for other local or systemic complications.Multivariate analyses of the propensity-matched cohort revealed that non-robotic minimally invasive surgery [odds ratio = 2.463(1.070–5.682);P = 0.034] was a significant independent risk factor for intra-abdominal infectious complications.CONCLUSION The findings showed that robotic surgery might improve short-term outcomes following minimally invasive radical gastrectomy by reducing intra-abdominal infectious complications.Susumu Shibasaki Koichi Suda Masaya Nakauchi Kenichi Nakamura Kenji Kikuchi Kazuki Inaba Ichiro Uyama 2020World Journal of Gastroenterology2020,26,11:8
11Numerical Simulation of Sand Erosion Phenomena in Rotor/Stator Interaction of Compressor显示文摘沙侵蚀是侵犯到一面墙的稳固的粒子引起严重机械损坏到墙表面的现象。这现象是典型煤气粒子的二阶段的狂暴的流动和流动地,粒子轨道和墙变丑与对方一起交往的一个多物理问题。在另一方面,在微粒环境操作的飞机引擎由于沙侵蚀受到表演和一生恶化。特别,飞机引擎的压缩机严重地被损坏。压缩机的流动地强烈有三个维、不稳定的性质。以便由于沙侵蚀估计恶化,为一台压缩机的沙侵蚀模拟在转子定子相互作用的考虑下面被要求。在现在的学习,我们把我们的三维的沙侵蚀预言代码用于一台单个阶段轴流压缩机。我们数字地在压缩机调查流动领域,粒子轨道,和侵蚀的墙形状的变化,到在压缩机澄清沙侵蚀的效果。Masaya Suzuki Kazuaki Inaba Makoto Yamamoto 2008Journal of Thermal Science2008,17,2:7
12Safety and efficacy of carbon dioxide insufflation during gastric endoscopic submucosal dissection显示文摘AIM: To compare the safety and efficacy of carbon dioxide(CO2) and air insufflation during gastric endoscopic submucosal dissection(ESD).METHODS: This study involved 116 patients who underwent gastric ESD between January and December 2009.After eliminating 29 patients who fit the exclusion criteria,87 patients,without known pulmonary dysfunction,were randomized into the CO2 insufflation(n = 36) or air insufflation(n = 51) groups.Standard ESD was performed with a CO2 regulation unit(constant rate of 1.4 L/min) used for patients undergoing CO2 insufflation.Patients received diazepam for conscious sedation and pentazocine for analgesia.Transcutaneous CO2 tension(Ptc CO2) was recorded 15 min before,during,and after ESD with insufflation.Ptc CO2,the correlation between Ptc CO2 and procedure time,and ESD-related complications were compared between the two groups.Arterial blood gases were analyzed after ESD in the first 30 patients(12 with CO2 and 18 with air insufflation) to assess the correlation between arterial blood CO2 partial pressure(Pa CO2) and Ptc CO2.RESULTS: There were no differences in respiratoryfunctions,median sedative doses,or median procedure times between the groups.Similarly,there was no significant difference in post-ESD blood gas parameters,including Pa CO2,between the CO2 and air groups(44.6 mm Hg vs 45 mm Hg).Both groups demonstrated median p H values of 7.36,and none of the patients exhibited acidemia.No significant differences were observed between the CO2 and air groups with respect to baseline Ptc CO2(39 mm Hg vs 40 mm Hg),peak Ptc CO2 during ESD(52 mm Hg vs 51 mm Hg),or median Ptc CO2 after ESD(50 mm Hg vs 50 mm Hg).There was a strong correlation between Pa CO2 and Ptc CO2(r = 0.66; P < 0.001).The incidence of Mallory-Weiss tears was significantly lower with CO2 insufflation than with air insufflation(0% vs 15.6%,P = 0.013).CO2 insufflation did not cause any adverse events,such as CO2 narcosis or gas embolisms.CONCLUSION: CO2 insufflation during gastric ESD results in similar blood gas levels as air insufflation,and also reduces the incidence of Mallory-Weiss tears.Jun Takada Hiroshi Araki Fumito Onogi Takayuki Nakanishi Masaya Kubota Takashi Ibuka Masahito Shimizu Hisataka Moriwaki 2015World Journal of Gastroenterology2015,21,26:6
13Lymphoepithelioma-like esophageal carcinoma with macroscopic reduction显示文摘Esophageal lymphoepithelioma-like carcinoma(LELC) is extremely rare. We report the first case of esopha-geal LELC showing macroscopic reduction. A 67-year-old male presented with dysphagia and, by endoscopic examination, was found to have a significantly raised tumor of 10 mm in diameter in the thoracic esophagus. The biopsied material showed esophageal cancer. We performed endoscopic submucosal dissection. However, the tumor became flattened, similar to a scar, in only 2 mo. Histologically, the carcinoma cells had infiltrated the submucosal layer. Prominent infiltration of T lymphoid cells that stained positive for CD8 was observed aroundthe carcinoma cells. Therefore, this lesion was consid-ered to be an LELC with poorly differentiated squamous cells. Because the margin was positive, an esophagec-tomy was performed. Carcinoma cells were detected in the neck in one lymph node. The staging was T1N0M1 b. However, the patient has been well, without adjuvant therapy or recurrence, for more than 5 years.Masaya Uesato Tuguaki Kono Tooru Shiratori Yasunori Akutsu Isamu Hoshino Kentarou Murakami Daisuke Horibe Tetsurou Maruyama Yoshihide Semba Ryuma Urahama Yukiko Ogura Takashi Oide Toru Tanizawa Hisahiro Matsubara 2014World Journal of Gastrointestinal Endoscopy2014,6,8:6
14Subvoxel light-sheet microscopy for high-resolution high-throughput volumetric imaging of large biomedical specimens显示文摘A key challenge when imaging whole biomedical specimens is how to quickly obtain massive cellular information over a large field of view(FOV).We report a subvoxel light-sheet microscopy(SLSM)method enabling high-throughput volumetric imaging of mesoscale specimens at cellular resolution.A nonaxial,continuous scanning strategy is developed to rapidly acquire a stack of large-FOV images with three-dimensional(3-D)nanoscale shifts encoded.Then,by adopting a subvoxel-resolving procedure,the SLSM method models these low-resolution,cross-correlated images in the spatial domain and can iteratively recover a 3-D image with improved resolution throughout the sample.This technique can surpass the optical limit of a conventional light-sheet microscope by more than three times,with high acquisition speeds of gigavoxels per minute.By fast reconstruction of 3-D cultured cells,intact organs,and live embryos,SLSM method presents a convenient way to circumvent the trade-off between mapping large-scale tissue(>100 mm3)and observing single cell(∼1-μm resolution).It also eliminates the need of complicated mechanical stitching or modulated illumination,using a simple light-sheet setup and fast graphics processing unit-based computation to achieve high-throughput,high-resolution 3-D microscopy,which could be tailored for a wide range of biomedical applications in pathology,histology,neuroscience,etc.Peng Fei Jun Nie Juhyun Lee Yichen Ding Shuoran Li Hao Zhang Masaya Hagiwara Tingting Yu Tatiana Segura Chih-Ming Ho Dan Zhu Tzung KHsiaic 2019Advanced Photonics2019,1,1:6
15Endoscopic ultrasonography can diagnose distal biliary strictures without a mass on computed tomography显示文摘AIM:To assess the diagnostic ability of endoscopic ultrasonography(EUS)for evaluating causes of dista biliary strictures shown on endoscopic retrograde chol angiopancreatography(ERCP)or magnetic resonance cholangiopancreatography(MRCP),even without iden tifiable mass on computed tomography(CT). METHODS:The diagnostic ability of EUS was retro spectively analyzed and compared with that of routine cytology(RC)and tumor markers in 34 patients with distal biliary strictures detected by ERCP or MRCP a Dokkyo Medical School Hospital from December 2005 to December 2008,without any adjacent mass or ec centric thickening of the bile duct on CT that could cause biliary strictures.Findings considered as benign strictures on EUS included preservation of the normasonographic layers of the bile duct wall,irrespective of the presence of a mass lesion.Other strictures were considered malignant.Final diagnosis of underlying diseases was made by pathological examination in 18 cases after surgical removal of the samples,and by clinical follow-up for>10 mo in 16 cases. RESULTS:Seventeen patients(50%)were finally di- agnosed with benign conditions,including 6'normal' subjects,while 17 patients(50%)were diagnosed with malignant disease.In terms of diagnostic ability,EUS showed 94.1%sensitivity,82.3%specificity,84.2% positive predictive value,93.3%negative predictive value(NPV)and 88.2%accuracy for identifying ma- lignant and benign strictures.EUS was more sensi- tive than RC(94.1%vs 62.5%,P=0.039).NPV was also better for EUS than for RC(93.3%vs 57.5%,P= 0.035).In addition,EUS provided significantly higher sensitivity than tumor markers using 100 U/mL as the cutoff level of carbohydrate antigen 19-9(94.1%vs 53%,P=0.017).On EUS,biliary stricture that was fi- nally diagnosed as malignant showed as a hypoechoic, irregular mass,with obstruction of the biliary duct and invasion to surrounding tissues. CONCLUSION:EUS can diagnose biliary strictures caused by malignant tumors that are undetectable on CT.Earlier detection by EUS would provide more therapeutic options for patients with early-stage pancreaticobiliary cancer.Yasuyuki Saifuku Michiko Yamagata Takero Koike Genyo Hitomi Kazunari Kanke Hidetaka Watanabe Toshimitsu Murohisa Masaya Tamano Makoto Iijima Keiichi Kubota Hideyuki Hiraishi 2010World Journal of Gastroenterology2010,16,2:5
16Factors 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 2017World Journal of Gastroenterology2017,23,11:5
17Shear wave elastography in hepatitis C patients before and after antiviral therapy显示文摘AIM To investigate shear wave(SW) propagation velocity in patients with untreated hepatitis C and patients with sustained virological response(SVR). METHODS A total of 136 hepatitis C patients [85 patients who had not received antiviral therapy(na?ve group) and 51 patients who had received antiviral therapy and subsequently achieved SVR of at least 24 wk(SVR group)] and 58 healthy volunteers and outpatients without liver disease(control group) underwent evaluation of liver stiffness by SW elastography(SWE). Various parameters were evaluated in the chronic hepatitis C patients at the time of SWE.RESULTS SW propagation velocity(Vs) was 1.23 ± 0.14 m/s in the control group, 1.56 ± 0.32 m/s in the SVR group, and 1.69 ± 0.31 m/s in the na?ve group. Significant differences were seen between the control group and the SVR group(P = 0.0000) and between the SVR group and the na?ve group(P = 0.01417). All four fibrosis markers were higher in the na?ve group than in the SVR group. In the na?ve group, Vs was positively correlated with alanine aminotransferase(ALT)(r = 0.5372), α feto protein(AFP)(r = 0.4389), type Ⅳ collagen(r = 0.5883), procollagen Ⅲ peptide(P-Ⅲ-P)(r = 0.4140), hyaluronic acid(r = 0.4551), and Mac-2 binding protein glycosylation isomer(M2BPGi)(r = 0.6092) and negatively correlated with albumin(r =-0.4289), platelets(r =-0.5372), and prothrombinactivity(r =-0.5235). On multiple regression analysis, Vs was the most strongly correlated with ALT(standard partial regression std β = 0.4039, P = 0.00000). In the SVR group, Vs was positively correlated with AFP(r = 0.6977), type IV collagen(r = 0.5228), P-Ⅲ-P(r = 0.5812), hyaluronic acid(r = 0.5189), and M2BPGi(r = 0.6251) and negatively correlated with albumin(r =-0.4283), platelets(r =-0.4842), and prothrombin activity(r =-0.4771). On multiple regression analysis, Vs was strongly correlated with AFP(standard partial regression std β = 0.5953, P = 0.00000) and M2BPGi(standard partial regression std β = 0.2969, P = 0.03363).CONCLUSION In hepatitis C patients, liver stiffness is higher in treatment-na?ve patients than in those showing SVR. SWE may be a predictor of hepatocarcinogenesis in SVR patients.Toshikuni Suda Osamu Okawa Rion Masaoka Yoshinori Gyotoku Naohiko Tokutomi Yasumi Katayama Masaya Tamano 2017World Journal of Hepatology2017,9,1:4
18High expressions of caveolins on the proliferating bile ductules in primary biliary cirrhosis显示文摘AIM: An increase in bile ductular structures is observed in diverse human liver diseases, especially in primary biliary cirrhosis (PBC). These structures harbor the progenitor cell component of the liver. Caveolins are cholesterol-binding proteins involved in the regulation of several intracellular processes including cholesterol transport. This study aims to examine the role of caveolin in PBC.METHODS: Immunohistochemical and Western blottingstudies were performed on human liver specimens obtained from patients with PBC and normal liver samples. The expression of caveolin (CAV)-1 and -2 was determined using specific antibodies.RESULTS: In normal liver, scanty immunostaining for CAV1 and -2 was observed in bile ductules. In PBC liver samples, the expression levels of CAV-1 and -2 were increased on proliferating bile ductules especially in stage 3 cases, but was sparse on interlobular bile duct in stage 1 specimens. Especially, the regenerating bile ductules at the interface of portal tracts and necrotic areas were immunostained intensely for CAV-1 and -2. These phenomena were confirmed by Western blot.CONCLUSION: The present results demonstrate increased expression of caveolins in proliferating bile ductules in PBC, which may be related to the homeostasis of cholesterol transport in regenerating bile ductules in PBC liver.Hiroaki Yokomori Masaya Oda Go Wakabayashi Masaki Kitajima Kazunori Yoshimura Masahiko Nomura Toshifumi Hibi 2005World Journal of Gastroenterology2005,11,24:4
19Expression of adhesion molecules on mature cholangiocytes in canal of Hering and bile ductules in wedge biopsy samples of primary biliary cirrhosis显示文摘AIM: To examine the expression of intercellular adhesion molecule-1 (ICAM-1) and lymphocyte function-associated antigen-1 (LFA-1) expression on canals of Hering (CoH)and bile ductules associated with the autoimmune process of bile duct destruction in primary biliary cirrhosis (PBC).METHODS: Ten wedged liver biopsies of PBC (five cases each of stages 2 and 3) were studied. The liver specimens were processed for transmission electron microscopy.Immunohistochemistry was performed using anti-ICAM-1 and anti-LFA-1 mouse mAbs. In situ hybridization was done to examine the messenger RNA expression of ICAM-1 in formalin-fixed, paraffin-embedded sections using peptide nucleic acid probes and the catalyzed signal amplification (CSA) technique. Immunogold-silver staining for electron microscopy was performed using anti-ICAM and anti-LFA-1 mouse mAbs. The immunogold particles on epithelial cells of bile ductules and cholangiocytes of CoH cells were counted and analyzed semi-quantitatively.Western blotting was performed to confirm ICAM-1 protein expression.RESULTS: In liver tissues of PBC patients, immunohistochemistry showed aberrant ICAM-1 expression on the plasma membrane of epithelial cells lining bile ductules,and also on mature cholangiocytes but not on hepatocytes in CoH. LFA-1-positive lymphocytes were closely associated with epithelial cells in bile ductules. ICAM-1 expression at protein level was confirmed by Western blot. In situ hybridization demonstrated ICAM-1 mRNA expression in bile ductules and LFA-1 mRNA in lymphocytes infiltrating the bile ductules. By immunoelectron microscopy, ICAM-1 was demonstrated on the basal surface of epithelial cells in bile ductules and on the luminal surfaces of cholangiocytes in damaged CoH. Cells with intermediate morphology resembling progenitor cells in CoH were not labeled with ICAM-1 and LFA-1.CONCLUSION: De novo expression of ICAM-1 both on mature cholangiocytes in CoH and epithelial cells in bile ductules in PBC implies that lymphocyte-induced destruction through adhesion by ICAM-1 and binding of LFA-1-expressing activated lymphocytes takes place not only in bile ductules but also in the CoH.Hiroaki Yokomori Masaya Oda Mariko Ogi Go Wakabayashi Shigeyuki Kawachi Kazunori Yoshimura Toshihiro Nagai Masaki Kitajima Masahiko Nomura Toshifumi Hibi 2005World Journal of Gastroenterology2005,11,28:4
20The prospects of regenerative medicine combined with rehabilitative approaches for chronic spinal cord injury animal models显示文摘Regenerative medicine has opened a window for functional recovery in acute-to-subacute phase spinal cord injury(SCI).By contrast,there are still only a few studies have focused on the treatment of the chronically injured spinal cord,in which cell-based regenerative medicine seems less effective.Since the majority of SCI patients are in the chronic phase,representing a major challenge for the clinical application of cellbased regenerative medicine.Although combined therapies for the treatment of chronic SCI have attracted attention of researchers and its potential importance is also widely recognized,there had been very few studies involving rehabilitative treatments to date.In a recent study,we have demonstrated for the first time that treadmill training combined with cell transplantation significantly promotes functional recovery even in chronic SCI,not only in additive but also in synergistic manner.Even though we have succeeded to outline the profiles of recovery secondary to the combination therapy,the mechanism underlying the effects remain unsolved.In this review article,we summarize the present progress and consider the prospect of the cell-based regenerative medicine particularly combined with rehabilitative approaches for chronic SCI animal models.Syoichi Tashiro Masaya Nakamura Hideyuki Okano 2017Neural Regeneration Research2017,12,1:4
