3Evolving concepts in bone infection: redefining “biofilm”,“acute vs. chronic osteomyelitis”, “the immune proteome” and “local antibiotic therapy”显示文摘Osteomyelitis is a devastating disease caused by microbial infection of bone. While the frequency of infection following elective orthopedic surgery is low, rates of reinfection are disturbingly high. Staphylococcus aureus is responsible for the majority of chronic osteomyelitis cases and is often considered to be incurable due to bacterial persistence deep within bone. Unfortunately, there is no consensus on clinical classifications of osteomyelitis and the ensuing treatment algorithm. Given the high patient morbidity,mortality, and economic burden caused by osteomyelitis, it is important to elucidate mechanisms of bone infection to inform novel strategies for prevention and curative treatment. Recent discoveries in this field have identified three distinct reservoirs of bacterial biofilm including: Staphylococcal abscess communities in the local soft tissue and bone marrow, glycocalyx formation on implant hardware and necrotic tissue, and colonization of the osteocyte-lacuno canalicular network(OLCN) of cortical bone. In contrast, S.aureus intracellular persistence in bone cells has not been substantiated in vivo, which challenges this mode of chronic osteomyelitis. There have also been major advances in our understanding of the immune proteome against S. aureus, from clinical studies of serum antibodies and media enriched for newly synthesized antibodies(MENSA), which may provide new opportunities for osteomyelitis diagnosis, prognosis, and vaccine development. Finally, novel therapies such as antimicrobial implant coatings and antibiotic impregnated 3D-printed scaffolds represent promising strategies for preventing and managing this devastating disease. Here, we review these recent advances and highlight translational opportunities towards a cure.Elysia A. Masters Ryan P. Trombetta Karen L. de Mesy Bentley Brendan F Boyce Ann Lindley Gill Steven R.

5Dietary polyphenols and colorectal cancer risk:The Fukuoka colorectal cancer study显示文摘AIM:To investigate the associations between dietary intake of polyphenols and colorectal cancer. METHODS:The study subjects were derived from the Fukuoka colorectal cancer study, a community-based case-control study. The study subjects were 816 cases of colorectal cancer and 815 community-based controls. The consumption of 148 food items was assessed by a computer-assisted interview. We used the consumption of 97 food items to estimate dietary intakes of total, tea and coffee polyphenols. The Phenol-Explorer database was used for 92 food items. Of the 5 foods which were not listed in the Phenol-Explorer Database, polyphenol contents of 3 foods (sweet potatoes, satoimo and daikon) were based on a Japanese study and 2 foods (soybeans and fried potatoes) were estimated by ORAC-based polyphenol contents in the United States Department of Agriculture Database. Odds ratios (OR) and 95%CI of colorectal cancer risk according to quintile categories of intake were obtained by using logistic regression models with adjustment for age, sex, residential area, parental history of colorectal cancer, smoking, alcohol consumption, body mass index 10 years before, type of job, leisure-time physical activity and dietary intakes of calcium and n-3 polyunsaturated fatty acids.RESULTS:There was no measurable difference in total or tea polyphenol intake between cases and controls, but intake of coffee polyphenols was lower in cases than in controls. The multivariate-adjusted OR of colorectal cancer according to quintile categories of coffee polyphenols (from the first to top quintile) were 1.00 (referent), 0.81 (95%CI:0.60-1.10), 0.65 (95%CI:0.47-0.89), 0.65 (95%CI:0.46-0.89) and 0.82 (95%CI:0.60-1.10), respectively (P trend = 0.07). Similar, but less pronounced, decreases in the OR were also noted for the third and fourth quintiles of total polyphenol intake. Tea polyphenols and non-coffee polyphenols showed no association with colorectal cancer risk. The sitespecific analysis, based on 463 colon cancer cases and 340 rectal cancer cases, showed an inverse association between coffee polyphenols and colon cancer. The multivariate-adjusted OR of colon cancer for the first to top quintiles of coffee polyphenols were 1.00 (referent), 0.92 (95%CI:0.64-1.31), 0.75 (95%CI:0.52-1.08), 0.69 (95%CI:0.47-1.01), and 0.68 (95%CI:0.46-1.00), respectively (P trend = 0.02). Distal colon cancer showed a more evident inverse association with coffee polyphenols than proximal colon cancer. The association between coffee polyphenols and rectal cancer risk was U -shaped, with significant decreases in the OR at the second to fourth quintile categories. There was also a tendency that the OR of colon and rectal cancer decreased in the intermediate categories of total polyphenols. The decrease in the OR in the intermediate categories of total polyphenols was most pronounced for distal colon cancer. Intake of tea polyphenols was not associated with either colon or rectal cancer. The associations of coffee consumption with colorectal, colon and rectal cancers were almost the same as observed for coffee polyphenols. The trend of the association between coffee consumption and colorectal cancer was statistically significant. CONCLUSION:The present findings suggest a decreased risk of colorectal cancer associated with coffee consumption.Zhen-Jie Wang Keizo Ohnaka Makiko Morita Kengo Toyomura Suminori Kono Takashi Ueki Masao Tanaka Yoshihiro Kakeji Yoshihiko Maehara Takeshi Okamura Koji Ikejiri Kitaroh Futami Takafumi Maekawa Yohichi Yasunami Kenji Takenaka Hitoshi Ichimiya Reiji Terasaka 2013World Journal of Gastroenterology2013,19,17:12
6Boron removal from metallurgical grade silicon by oxidizing refining显示文摘A purification process was developed to remove impurity element boron from the metallurgical grade silicon by the electric arc furnace refining. The thermodynamic equilibria calculation and experiment to remove boron in the oxidizing atmosphere were performed and analyzed. Boron is removed as the gaseous species BxOy and BxHzOy in O2 and H2O-O2 atmosphere respectively. The equilibrium pressure of BxHzOy is 105-1010 times that of BxOy. Boron is removed and its content in silicon is reduced from 18× 10-6 to 2×10-6 in the Ar-H2O-O2 atmosphere in the electric arc furnace.伍继君 马文会 杨斌 戴永年 K. MORITA 2009中国有色金属学会会刊:英文版2009,19,2:12
7An updated review of gastric cancer in the next-generation sequencing era:Insights from bench to bedside and vice versa显示文摘Gastric cancer(GC)is one of the most common malignancies and remains the second leading cause of cancer-related death worldwide.There is an increasing understanding of the roles that genetic and epigenetic alterations play in GCs.Recent studies using nextgeneration sequencing(NGS)have revealed a number of potential cancer-driving genes in GC.Whole-exome sequencing of GC has identified recurrent somatic mutations in the chromatin remodeling gene ARID1A and alterations in the cell adhesion gene FAT4,a member of the cadherin gene family.Mutations in chromatin remodeling genes(ARID1A,MLL3 and MLL)have been found in 47%of GCs.Whole-genome sequencing and whole-transcriptome sequencing analyses have also discovered novel alterations in GC.Recent studies of cancer epigenetics have revealed widespread alterations in genes involved in the epigenetic machinery,such as DNA methylation,histone modifications,nucleosome positioning,noncoding RNAs and microRNAs.Recent advances in molecular research on GC have resulted in the introduction of new diagnostic and therapeutic strategies into clinical settings.The antihuman epidermal growth receptor 2(HER2)antibody trastuzumab has led to an era of personalized therapy in GC.In addition,ramucirumab,a monoclonal antibody targeting vascular endothelial growth factor receptor(VEGFR)-2,is the first biological treatment that showed survival benefits as a single-agent therapy in patients with advanced GC who progressed after firstline chemotherapy.Using NGS to systematically identify gene alterations in GC is a promising approach with remarkable potential for investigating the pathogenesis of GC and identifying novel therapeutic targets,as well as useful biomarkers.In this review,we will summarize the recent advances in the understanding of the molecular pathogenesis of GC,focusing on the potential use of these genetic and epigenetic alterations as diagnostic biomarkers and novel therapeutic targets.Hiroyuki Yamamoto Yoshiyuki Watanabe Tadateru Maehata Ryo Morita Yoshihito Yoshida Ritsuko Oikawa Shinya Ishigooka Shun-ichiro Ozawa Yasumasa Matsuo Kosuke Hosoya Masaki Yamashita Hiroaki Taniguchi Katsuhiko Nosho Hiromu Suzuki Hiroshi Yasuda Yasuhisa Shinomura Fumio Itoh 2014World Journal of Gastroenterology2014,20,14:12
8Differentiation of focal liver lesions using three-dimensional ultrasonography: Retrospective and prospective studies显示文摘AIM: To differentiate focal liver lesions based on enhancement patterns using three-dimensional ultrasonography (3D US) with perflubutane-based contrast agent.METHODS: Two hundred and eighty two patients with focal liver lesions,including 168 hepatocellular carcinomas (HCCs),63 metastases,40 hemangiomas and 11 focal nodular hyperplasias (FNHs),were examined by 3D US with perflubutane-based contrast agent.Tomographic ultrasound images and sonographic angiograms were reconstructed.Among 282 lesions,enhancement patterns of 163 lesions between January 2007 and October 2007 were analyzed retrospectively.Then from November 2007 to May 2008,compared with contrast-enhanced (CE) 2D US,CE 3D US was performed on 119 lesions for prospective differential diagnosis.Sensitivity,specificity,area under receiver operating characteristic curve (Az) and inter-reader agreement were assessed.RESULTS: With the tridimensional view,dominant enhancement patterns were revealed as diffuse enhancement or peripheral ring-like enhancement,followed with washout change for HCCs or metastases,respectively,and peripheral nodular enhancement or diffuse enhancement with spoke-wheel arteries,followed by persistent enhancement for hemangiomas or FNHs,respectively.At CE 3D US,the prospective differentiation of lesions showed sensitivity 92% (mean for two readers),specificity 91% and Az value 0.95 for HCCs,84%,97%,and 0.95 for metastases,91%,98%,and 0.98 for hemangiomas and 80%,99%,and 0.99 for FNHs,respectively,while good to excellent inter-reader agreement was achieved.No significant difference exists between prospective diagnosis accuracy at CE 3D US and that at CE 2D US.CONCLUSION: CE 3D US provides a spatial perspective for liver tumor enhancement,and could help in differentiating focal liver lesions.Kazushi Numata Manabu Morimoto Akito Nozaki Michio Ueda Masaaki Kondo Satoshi Morita Katsuaki Tanaka 2010World Journal of Gastroenterology2010,16,17:12
9西藏南部普莫雍错19 cal ka BP以来高分辨率环境记录显示文摘利用西藏南部普莫雍错深水湖区获取的3.8m长湖芯,对湖芯中25个样品的植物碎屑进行筛选和有机碳同位素测定,在确定植物来源的前提下进行了14C测定,结合表层样品的过剩210Pb衰变计算的沉积速率对整个湖芯的14C测年及其碳库效应进行了系统校正,结果显示该湖芯完整地覆盖了19calkaBP以来的时间尺度.通过对湖芯TOC,IC,粒度和孢粉的分析,发现该湖在16.2calkaBP之前为一个水深较浅的湖泊,尽管温度升高导致冰川开始融化,湖区环境仍然具有冷干的特征;16.2~11.8calkaBP,沉积环境剧烈而频繁的波动,14.2和11.8calkaBP左右的2次冷事件可能是老仙女木和新仙女木事件的反映.11.8calkaBP之后,已经形成了现今状态的深水湖泊,冰川融水的补给使得湖泊水温较低,受到湖泊水体影响的沉积物环境代用指标对温暖条件的响应并不明显.通过普莫雍错湖与西藏南部相同时代的不同湖泊沉积物记录的比较,发现末次冰消期开始的气候转暖对青藏高原东南部影响更加显著,反映了西南季风自冰消期以后逐渐加强、向高原内部推移的过程,以冰川融水补给为主的湖泊对冷事件的响应更加明显.全新世以来,西南季风对整个西藏南部区域发挥着控制性影响.吕新苗 朱立平 NISHIMURA Mitsugu MORITA Yoshimune WATANABE Takahiro NAKAMURA Toshio 汪勇 2011科学通报2011,56,24:11
10A high-resolution environmental change record since 19 cal ka BP in Pumoyum Co, southern Tibet显示文摘A 380-cm-long sediment core was acquired from the deep water area of Pumoyum Co, southern Tibet. Twenty-five plant residue samples were selected, and organic carbon stable isotopes were obtained using the AMS 14 C chronological method. The 14 C age and carbon reservoir effect were calibrated with surface sedimentation rate measurements using 210 Pb dating. Results showed that the core sediment deposited over 19 cal ka BP. Based on a multi-proxy analysis of TOC and IC contents, grain size and pollen assemblage data, the palaeoclimatic evolution of Pumoyum Co was reconstructed since the last glacial. Pumoyum Co was a shallow lake prior to 16.2 cal ka BP; although the glacier around the lake began to melt due to increasing temperatures, climate was still cold and dry. In the interval of 16.2-11.8 cal ka BP, the sedimentary environment fluctuated drastically and frequently. Two cold-events occurred at 14.2 and 11.8 cal ka BP, and these may correspond to the Older Dryas and the Younger Dryas events, respectively. After 11.8 cal ka BP, Pumoyun Co developed into the deep lake as it is now. The lake water temperature was relatively lower at that time because of influx of cold water from glacial meltwater entering the lake. As a result, the multi-proxy indicators showed no sign of warm conditions. Comparisons between the sedimentary record of Pumoyum Co with that of other lakes of the same age in southern Tibet indicate a warmer climate following the last deglaciation influenced the southeastern Tibetan Plateau. These results imply that the southwest Asian monsoon gradually became stronger since the deglaciation during its expansion to the inner plateau. The glacial-supplied water of the lake responded sensitively to cold-events. The entire southern Tibet region was dominantly influenced climatically by the southwest Asian monsoon during the Holocene.LU XinMiao ZHU LiPing NISHIMURA Mitsugu MORITA Yoshimune WATANABE Takahiro NAKAMURA Toshio WANG Yong 2011Chinese Science Bulletin2011,56,27:10
11Effects 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 2013World Journal of Gastroenterology2013,19,39:9

13Quality of life in gastric cancer显示文摘AIM: To summarize the empirical research on assessing quality of life (QOL) in patients with gastric carcinoma. METHODS: Literature searches were conducted in MedLine from 1966 to February 2004. RESULTS: Twenty-six studies were identified. QOL was used as an outcome measure in virtually all identified studies, such as those examining the effects of gastric cancer and various medical or surgical treatments in the patients. QOL was assessed mainly with generic measures; the social dimensions of QOL were largely neglected. The lack of gastric cancer-specific QOL measures hampers QOL research up to now. The gastric cancer-specific EORTCQLQ-STO22 and the FACT-Ga are important additions to the arsenal of disease-specific QOL measures. In most of the studies, the label QOL is used for questionnaires, which only assess symptoms or performance status, or are physician-reported rather than patient-reported outcomes. CONCLUSION: QOL in patients with gastric cancer deserves more systematic studies, especially as one of the outcome measures in randomized clinical trials. Results of studies that include QOL in patients with gastric cancer should be applied in clinical care, which aims at improving QOL of these patients.Ad A.Kaptein Satoshi Morita Junichi Sakamoto 2005World Journal of Gastroenterology2005,11,21:8

15Magnifying endoscopy in upper gastroenterology for assessing lesions before completing endoscopic removal显示文摘Any prognosis of gastrointestinal (GI) cancer is closely related to the stage of the disease at diagnosis.Endoscopic submucosal dissection (ESD) and en bloc endoscopic mucosal resection (EMR) have been performed as curative treatments for many early-stage GI lesions in recent years.The technologies have been widely accepted in many Asian countries because they are minimally invasive and supply thorough histopathologic evaluation of the specimens.However,before engaging in endoscopic therapy,an accurate diagnosis is a precondition to effecting the complete cure of the underlying malignancy or carcinoma in situ.For the past few years,many new types of endoscopic techniques,including magnifying endoscopy with narrow-band imaging (MENBI),have emerged in many countries because these methods provide a strong indication of early lesions and are very useful in determining treatment options before ESD or EMR.However,to date,there is no comparable classification equivalent to 'Kudo's Pit Pattern Classification in the colon',for the upper GI,there is still no clear internationally accepted classification system of magnifying endoscopy.Therefore,in order to help unify some viewpoints,here we will review the defining optical imaging characteristics and the current representative classifications of microvascular and microsurface patterns in the upper GI tract under ME-NBI,describe the accurate relationship between them and the pathological diagnosis,and their clinical applications prior to ESD or en bloc EMR.We will also discuss assessing the differentiation and depth of invasion,defying the lateral spread of involvement and targeting biopsy in real time.Ning-Li Chai En-Qiang Ling-Hu Yoshinori Morita Daisuke Obata Takashi Toyonaqa Takeshi Azuma Ben-Yan Wu 2012World Journal of Gastroenterology2012,18,12:7
16Indicators of sorafenib efficacy in patients with advanced hepatocellular carcinoma显示文摘AIM:To determine significant indicators for the efficacy of sorafenib in patients with advanced hepatocellular carcinoma(HCC).METHODS:A total of 46 patients with Barcelona Clinic Liver Cancer stage C who received sorafenib for more than 30 d at the Iizuka Hospital from June 2009 to December 2012 were enrolled in this study.Multivariate and univariate analyses were performed to evaluate the associations of hepatic function according to Child-Pugh grade,location and size of the largest tumor and adverse events of sorafenib treatment,such as hand-foot syndrome(HFS),hypertension,diarrhea,and alopecia,with the efficacy of treatment,as measured by overall survival(OS)and time to progression(TTP).RESULTS:Patients included 39 men and 7 women whose ages ranged from 48 to 85 years(70.6±9.6years).HCC was classified according to etiology as follows:hepatitis C virus(n=26),hepatitis B virus(n=9),and other(n=11).Liver function in patients was categorized as Child-Pugh grade A(n=30)or B(n=16).Tumors were categorized by size[<5 cm(n=33)or>5 cm(n=13)]and the location of the largest tumor was used to categorize patients with intrahepatic(n=28)or extrahepatic(n=18)HCC.HFS,hypertension,diarrhea,and alopecia were present in22(47.8%),19(41.3%),15(32.6%)and 7 patients(15.2%),respectively.The median OS of all patients was 373 d and the median TTP was 112 d.The etiology of HCC did not correlate with the median OS and TPP.The median OS of patients with tumors<5 cm was significantly longer than those with larger tumors(496 vs 245 d;HR=0.19,95%CI:0.07-0.48;P<0.01).According to the results of a multivariate analysis,the size of the largest tumor affected OS(HR=0.22,95%CI:0.08-0.59;P<0.01).The median TTP was significantly longer in patients with extrahepatic compared to intrahepatic major HCC(224 vs 98 d;HR=0.32;95%CI:0.14-0.67;P<0.01).The median TTP of patients with HFS was significantly longer than those without it(195 d vs 83 d;HR=0.41,95%CI:0.20-0.82;P<0.05),and the median TTP was significantly longer in patients with hypertension(195 d vs84 d;HR=0.43,95%CI:0.21-0.84;P<0.05).According to the results of the multivariate analysis,extrahepatic major HCC(HR=0.36,P<0.01)and HFS(HR=0.44,P<0.05)prolonged TTP.CONCLUSION:Extrahepatic major HCC and HFS are associated with prolonged TTP and are useful indicators for judging the efficacy of sorafenib treatment.Masayoshi Yada Akihide Masumoto Kenta Motomura Hirotaka Tajiri Yusuke Morita Hideo Suzuki Takeshi Senju Toshimasa Koyanagi 2014World Journal of Gastroenterology2014,20,35:7
17Utility of tricalcium phosphate and osteogenic matrix cell sheet constructs for bone defect reconstruction显示文摘AIM: To determine the effects of transplanting osteogenic matrix cell sheets and beta-tricalcium phosphate(TCP) constructs on bone formation in bone defects.METHODS: Osteogenic matrix cell sheets were prepared from bone marrow stromal cells(BMSCs), and a porous TCP ceramic was used as a scaffold. Three experimental groups were prepared, comprised of TCP scaffolds(1) seeded with BMSCs;(2) wrapped with osteogenic matrix cell sheets; or(3) both. Constructs were implanted into a femoral defect model in rats and bone growth was evaluated by radiography, histology, biochemistry, and mechanical testing after 8 wk. RESULTS: In bone defects, constructs implanted with cell sheets showed callus formation with segmentalor continuous bone formation at 8 wk, in contrast to TCP seeded with BMSCs, which resulted in bone nonunion. Wrapping TCP constructs with osteogenic matrix cell sheets increased their osteogenic potential and resulting bone formation, compared with conventional bone tissue engineering TCP scaffolds seeded with BMSCs. The compressive stiffness(mean ± SD) values were 225.0 ± 95.7, 30.0 ± 11.5, and 26.3 ± 10.6 MPa for BMSC/TCP/Sheet constructs with continuous bone formation, BMSC/TCP/Sheet constructs with segmental bone formation, and BMSC/TCP constructs, respectively. The compressive stiffness of BMSC/TCP/Sheet constructs with continuous bone formation was significantly higher than those with segmental bone formation and BMSC/TCP constructs.CONCLUSION: This technique is an improvement over current methods, such as TCP substitution, and is useful for hard tissue reconstruction and inducing earlier bone union in defects.Tomoyuki Ueha Manabu Akahane Takamasa Shimizu Yoshinobu Uchihara Yusuke Morita Naoya Nitta Akira Kido Yusuke Inagaki Kenji Kawate Yasuhito Tanaka 2015World Journal of Stem Cells2015,7,5:7
18Speckle tracking echocardiography to assess regional ventricular function in patients with apical hypertrophic cardiomyopathy显示文摘AIM To explore regional systolic strain of midwall and endocardial segments using speckle tracking echocardiography in patients with apical hypertrophic cardiomyopathy(HCM).METHODS We prospectively assessed 20 patients(mean age 53 ± 16 years,range:18-81 years,10 were male),with apical HCM. We measured global longitudinal peak systolic strain(GLPSS) in the midwall and endocardium of the left ventricle. RESULTS The diastolic thickness of the 4 apical segments was 16.25 ± 2.75 mm. All patients had a normal global systolicfunction with a fractional shortening of 50% ± 8%. In spite of supernormal left ventricular(LV) systolic function,midwall GLPSS was decreased in all patients,more in the apical(-7.3% ±-8.8%) than in basal segments(-15.5% ±-6.93%),while endocardial GLPPS was significantly greater and reached normal values(apical:-22.8% ±-7.8%,basal:-17.9% ±-7.5%). CONCLUSION This study shows that two-dimensional strain was decreased mainly confined to the mesocardium,while endocardium myocardial deformation was preserved in HCM and allowed to identify subclinical LV dysfunction. This transmural heterogeneity in systolic strain had not been previously described in HCM and could be explained by the distribution of myofibrillar disarray in deep myocardial areas. The clinical application of this novel finding may help further understanding of the pathophysiology of HCM.María Cristina Saccheri Tomás Francisco Cianciulli Luis Alberto Morita Ricardo JoséMéndez Martín Alejandro Beck Juan Enrique Guerra Alberto Cozzarin Luciana Jimena Puente Lorena Romina Balletti Jorge Alberto Lax 2017World Journal of Cardiology2017,9,4:7
19Feasibility and safety of endoscopic submucosal dissection for lower rectal tumors with hemorrhoids显示文摘AIM: To evaluate the feasibility and safety of endoscopic submucosal dissection(ESD) for lower rectal lesions with hemorrhoids.METHODS: The outcome of ESD for 23 lesions with hemorrhoids(hemorrhoid group) was compared with that of 48 lesions without hemorrhoids extending to the dentate line(non-hemorrhoid group) during the same study period. RESULTS: Median operation times(ranges) in the hemorrhoid and non-hemorrhoid groups were 121(51-390) and 130(28-540) min. The en bloc resection rate and the curative resection rate in the hemorrhoid group were 96% and 83%, and they were 100% and 90% in the non-hemorrhoid group, respectively. In terms of adverse events, perforation and postoperative bleeding did not occur in both groups. In terms of the clinical course of hemorrhoids after ESD, the rate of complete recovery of hemorrhoids after ESD in lesions with resection of more than 90% was significantly higher than that in lesions with resection of less than 90%.CONCLUSION: ESD on lower rectal lesions with hemorrhoids could be performed safely, similarly to that on rectal lesions extending to the dentate line without hemorrhoids. In addition, all hemorrhoids after ESD improved to various degrees, depending on the resection range.Shinwa Tanaka Takashi Toyonaga Yoshinori Morita Namiko Hoshi Tsukasa Ishida Yoshiko Ohara Tetsuya Yoshizaki Fumiaki Kawara Eiji Umegaki Takeshi Azuma 2016World Journal of Gastroenterology2016,22,27:6
20Trisomy 3 may predict a poor response of gastric MALT lymphoma to Helicobacter pylori eradication therapy显示文摘AIM: To investigate the relation of the response to Helicobacter pylori eradication therapy to the depth of tumor invasion and chromosome abnormalities in patients with mucosaassociated lymphoid tissue (MALT) lymphoma and to determine the clinical value of aneuploidy.METHODS: We studied 13 patients with localized gastric MALT lymphoma of stage E1. Before eradication therapy,the depth of tumor invasion was assessed by endoscopic ultrasonography in 8 patients and by endoscopic examination and gastrointestinal series in the remaining patients. To detect chromosomal abnormalities, paraffin-embedded tissue sections of diagnostic biopsy specimens underwent tissuefluorescence in situ hybridization (FISH), using chromosomespecific α-satellite DNA probes for chromosomes 3,7,12,and 18 and YAC clones for t(11;18)(q21;q21).RESULTS: Seven of the 13 patients had complete regression(CR) in response to H pylori eradication therapy. No patient with CR had submucosal tumor invasion. Trisomy 18 was seen in 1 patient with CR, and both trisomies 12 and 18 were present in another patient with CR. All patients with no response or progressive disease had deep submucosal tumor invasion and showed t(11;18)(q21;q21) or trisomy 3. Trisomy 7 was not detected in this series of patients.CONCLUSION: The depth of tumor invasion is an accurate predictor of the response of stage E1 MALT lymphoma to H pylori eradication therapy and is closely associated with the presence of chromosomal abnormalities. Trisomy 3 may predict the aggressive development of MALT lymphoma.Sawako Taji Kenichi Nomura Yosuke Matsumoto Hideaki Sakabe Naohisa Yoshida Shoji Mitsufuji Kazuhiro Nishida Shigeo Horiike Shigeo Nakamura Masuji Morita Masafumi Taniwaki 2005World Journal of Gastroenterology2005,11,1:6
