1Causal role of Helicobacter pylori infection in gastric cancer显示文摘胃的癌症是在世界,为在亚洲的所有癌症盒子的一个大比例的财务,拉丁美洲,和在欧洲的一些国家上的第二很经常的癌症。Helicobacter pylori (H pylori ) 被认为是在萎缩性胃炎的发展起一个特定的作用,它多代表最公认的小径在走肠类型的胃的致癌作用。最近的研究建议那联合招待基因因素,细菌的毒力因素,并且环境并且生活方式因素决定胃的损坏和 H pylori 感染的最终的临床的结果的严厉。胃的癌症的领先的原因应该导致有效根除策略的 H pylori 的精液的发现。胃的癌症的预防要求更好屏蔽的策略为根除识别候选人。Takafumi Ando Yasuyuki Goto Osamu Maeda Osamu Watanabe Kazuhiro Ishiguro Hidemi Goto 2006World Journal of Gastroenterology2006,12,2:29
2Transarterial chemoembolization for hepatocellular carcinoma: A review of techniques显示文摘Hepatocellular carcinoma(HCC)is one of the most common malignant diseases worldwide.While curative therapies,including resection,liver transplantation,and percutaneous ablation(percutaneous ethanol injection and radiofrequency ablation),are applicable for only a portion of the HCC population,transcatheter arterial chemoembolization(TACE)has been recognized as an effective palliative treatment option for patients with advanced HCC.TACE is also used even for single HCCs in which it is difficult to perform surgical resection or locoregional treatment due to systemic co-morbidities or anatomical problems.TACE has become widely adopted in the treatment of HCC.By using computed tomography-angiography,TACE is capable of performing diagnosis and treatment at the same time.Furthermore,TACE plays an important role in the multidisciplinary treatment for HCC when combined with other treatment.In this review,we first discuss the history of TACE,and then review the previous findings about techniques of achieving a locoregional treatment effect(liver infarction treatment,e.g.,ultra-selective TACE,balloon-occluded TACE),and the use of TACE as a drugdelivery system for anti-cancer agents(palliative,e.g.,platinum complex agents,drug-eluting beads)for multiple lesions.Norihiro Imai Masatoshi Ishigami Yoji Ishizu Teiji Kuzuya Takashi Honda Kazuhiko Hayashi Yoshiki Hirooka Hidemi Goto 2014World Journal of Hepatology2014,6,12:24
3城市地表热通量遥感反演及与下垫面关系分析显示文摘选择日本埼玉县熊谷市为研究区,应用ASTER热红外遥感图像,采用PCACA模型以及理论定位算法,对城市地表热通量的相关参数进行反演,进而分析城市下垫面不同土地覆盖类型对地表热通量以及能量平衡的影响。结果表明,PCACA模型应用于城市区域地表通量估算是可行的。这种算法可以大大减少在下垫面结构复杂的城市区域进行地表热通量估算时所需的参数,并有效降低研究结果的不确定性。研究发现,城乡不同下垫面地表覆盖类型对地表热通量的影响差异显著。不同地表下垫面类型的波文比由大到小顺序依次为:工业用地>住宅用地>交通用地>公共设施用地>旱田>公共绿地>水域。在相同的外部气象条件下,与城市周边的植被覆盖区相比,城市人工建筑用地具有较高的显热通量,较低的潜热通量,以及较高的波文比。由于城市地表显热通量和波文比明显高于周边植被覆盖地表,导致城市地表向低层大气供热的增加,这是城市热岛效应形成的重要机制之一。刘越 Shintaro Goto 庄大方 匡文慧 2012地理学报2012,67,1:21
4动脉粥样硬化血栓形成门诊患者1年内心血管事件的发生率显示文摘背景:目前,有关社区中动脉粥样硬化血栓形成稳定患者心血管(cardiovascular,CV)事件发生率的资料比较少,既往也无国际性队列研究对冠状动脉病(coronary artery disease,CAD)、脑血管病(cerebrovascular disease,CVD)、外周动脉病(peripheral arterial disease,PAD)确诊患者以及此类疾病高危患者不同事件的发生率进行评估。 目的:在患有动脉疾病的门诊患者或存在多个动脉粥样硬化血栓形成危险因素的门诊患者中确定当今世界1年内CV事件的发生率。 设计、地点及参试者:“减少动脉粥样硬化血栓形成维系健康(Reduction of Artherotllrombosis for Continued Health,REACH)”注册研究是一项国际前瞻性队列研究。研究人员于2003—2004年从44个国家、5587名医生入选68236例已确诊的动脉粥样硬化性血管病患者(CAD、PAD、CVD;n=55814)以及至少存在3个动脉粥样硬化血栓形成危险因素的患者(n=12422)。 主要观测指标:CV死亡、心肌梗死(myocardial infarction,MI)及卒中的发生率。结果:截至2006年7月,共有95.22%的患者(n=64977)提供了1年内的结局。心血管死亡、MI及卒中的总体发生率为4.24%;动脉粥样硬化性血管病患者为4.69%,仅存在多个危险因素的患者为2.15%。CAD、CVD及PAD患者CV死亡、MI及卒中的总体发生率分别为4.52%、6.47%和5.35%。CAD、CVD及PAD患者发生终点事件(即CV死亡、MI、卒中)以及因动脉粥样硬化血栓形成事件入院的几率分别为15.20%、14.53%和21.14%。上述事件发生率随症状性动脉疾病病变部位数量的增加而增加,仅存在危险因素的患者为5.31%,有1处症状性动脉疾病的患者为12.58%,有2处症状性动脉疾病的患者为21.14%,有3处症状性动脉疾病的患者为26.27%(趋势P〈0.001)。 结论:在这项当代大型国际研究中,患有动脉粥样硬化性血管病的门诊患者以及有动脉粥样硬化血栓形成危险的门诊患者CV事件的年发生率相对较高。存在多部位病变者CV事件的1年发生率升高。Gabriel Steg Deepak L.

5Interleukin-17 levels in Helicobacter pylori-infected gastric mucosa and pathologic sequelae of colonization显示文摘AIM: To determine the role of interleukin (IL)-17 in gastric ulcerogenesis. METHODS: Thirty-six gastric ulcer (GU) patients and 29 non-ulcer (NU) patients were enrolled in this study. Mucosal biopsy samples were obtained from the gastric antrum and GU site during endoscopy. Samples were used in in situ stimulation for 48 h in the presence of 10 μg/mL phytohemagglutinin-P (PHA), histological examination, and Helicobacter pylori(H pylori) culture. IL-17 and IL-8 protein levels in culture supernatants were assayed by ELISA. IL-17 mRNA expression was analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). H pylori cagA and vacA status was assessed by reverse hybridization using a line probe assay (LiPA). IL-8 levels in culture supernatants were assayed after AGS cells were co-cultured with H pylori strain 26 695 or recombinant human (rh) IL-17. RESULTS: All 36 GU patients and 15 of 29 NU patients were found to be H pylori-positive, while 14 NU patients were H pylori-negative. All 51 H pylori strains from both GU and NU patients were cagA- and vacAs1/m1-positive. Antral mucosal tissues from H pylori-positive patients contained significantly (H pylori-positive NU patients: median 467 pg/mg/protein, range 53-2 499; H pylori-negative NU patients: median 104 pg/mg/protein, range 16-312, P<0.0005) higher levels of IL-17 than those from uninfected patients. IL-17 levels at the ulcer site were significantly (ulcer site: median 1356 pg/mg/protein, range 121-1 3730; antrum: median 761 pg/mg/protein, range 24-7 620, P<0.005) higher than those at distant sites in the antrum. Biopsies from H pylori-positive GU and NU patients showed IL-17 mRNA expression in all samples whereas those from the antrum of the H pylori-negative controls showed no detectable expression. A significant correlation was seen between IL-17 and IL-8 levels at each biopsy site (ulcer: r= 0.62, P<0.0001; antrum: r = 0.61, P<0.0001) in GU patients. RhIL-17 and H pylori strain 26 695 each stimulated IL-8 production from AGS cells. CONCLUSION: IL-17 may play an important role in the inflammatory response to H pylori colonization, and may ultimately influence the outcome of H pylori-associated diseases that arise within the context of gastritis.Tomokazu Mizuno Takafumi Ando Kazuo Nobata Tomoyuki Tsuzuki Osamu Maeda Osamu Watanabe Masaaki Minami Kenji Ina Kazuo Kusugami Richard M.

6Application of cold drawn lamellar microstructure for developing ultra-high strength wires显示文摘Composite materials having lamellar structure are known to have a good combination of high strength and ductility. They are widely used in the fields of automobiles, civil engineering and construction, machines and many other industries. An application of lamellar microstructure for developing ultra-high strength steel wires was studied and discussed. Based on the experimental results, the relationships between the strength increase and microstructure development during the cold wire drawing were studied to reveal the strengthening mechanism. As cold drawing proceeds, the wire strength extremely increases, the microstructure changes from large single crystal lamellar structure to very fine polycrystalline lamellar one which has nano-sized grains, high dislocation density and amorphous regions. From the results obtained, it is concluded that heavy cold drawing technique is an effective method for lamellar composite to get high strength wires. Furthermore, formation process of the best microstructure for producing the ultra-high strength wires was also discussed.S. Goto R. Kirchheim T . Al-Kassab C. Borchers 2007中国有色金属学会会刊:英文版2007,17,6:15
7Cytomegalovirus infection in severe ulcerative colitis patients undergoing continuous intravenous cyclosporine treatment in Japan显示文摘AIM: To investigate active cytomegalovirus (CMV) infection following the cyclosporine A (CyA) treatment of steroid-refractory ulcerative colitis (UC).METHODS: Twenty-three patients with severe UC not responding to steroid therapy (male 14, and female 9) enrolled at Nagoya University Hospital from 1999 to 2005. They received continuous intravenous infusion of CyA (average 4 mg/kg per day) for 1 mo. Serum and colonic biopsy samples were collected before CyA treatment and 4 d, 10 d, 20 d, and 30 d after treatment. Patients were evaluated for CMV by using serology (IgM antibody by ELISA), quantitative real-time PCR for CMV DNA, and histopathological assessment of hematoxylin and eosin (HE)-stained colonic biopsies. CMV infection was indicated by positive results in any test. RESULTS: No patients had active CMV infection before CyA treatment. Eighteen of 23 UC patients treated with CyA were infected with active CMV (IgM antibody in 16/23 patients, 69.6%; CMV DNA in 18/23 patients, 78.2%; and inclusion bodies in 4/23 patients, 17.3%). There was no difference in the active CMV-infection rate between males and females. Active CMV infection was observed after approximately 8 d of CyA treatment, leading to an exacerbation of colitis. Fifteen of these 18 patients with active CMV infection (83.3%) required surgical treatment because of severe deteriorating colitis. Treatment with ganciclovir rendered surgery avoidable in three patients. CONCLUSION: Our results suggest that active CMVinfection in severe UC patients treated with CyA is associated with poor outcome. Further, ganciclovir is useful for treatment of CMV-associated UC after immuno-suppressive therapy.Masaaki Minami Michio Ohta Teruko Ohkura Takafumi Ando Naoki Ohmiya Yasumasa Niwa Hidemi Goto 2007World Journal of Gastroenterology2007,13,5:13
8Refractory gastric ulcer with abundant IgG4-positive plasma cell infiltration: A case report显示文摘We describe a 77-year-old man with refractory gastric ulcer that worsened after Helicobacter pylori eradication therapy.Pathology showed marked infiltration of IgG4-positive plasma cells in the gastric lesions,which led us to suspect IgG4-related sclerosing disease.To the best of our knowledge,this is the first report of IgG4-related gastric ulcer without the main manifestation of autoimmune pancreatitis.Takayoshi Fujita Takafumi Ando Masatoshi Sakakibara Waki Hosoda Hidemi Goto 2010World Journal of Gastroenterology2010,16,17:13
92018 update of expert consensus statement on antiplatelet therapy in East Asian patients with ACS or undergoing PCI显示文摘East Asians are the most populous race in the world and their health status is an important global issue.Compared with Caucasian populations, East Asian patients have a different benefit/risk ratio when using antithrombotic treatment. Despite this observation, treatment strategies in East Asian patients are mostly based on the American and European guidelines. Despite a lower platelet inhibitory response to clopidogrel, East Asian patients show a similar or even a lower rate of ischemic event occurrence and higher bleeding risk compared with Caucasian patients. For potent P2Y_(12) inhibitors(ticagrelor and prasugrel),East Asian patients have shown less favorable net clinical benefits compared with Caucasian patients,which may be related to differences in pharmacokinetic/pharmacodynamic profiles and therapeutic zone of antiplatelet effect. This updated consensus mainly focuses on state-of-the-art and current controversies in the East Asian population. In addition, when East Asian patients are administered potent P2Y_(12) receptor inhibitors, the strategies and ongoing trials to overcome the related hurdles are discussed.Yong Huo Young-Hoon Jeong Yanjun Gong Daowen Wang Ben He Jiyan Chen Guosheng Fu Yundai Chen Jianping Li Yi Li Shinya Goto Udaya S.Tantry Paul A.Gurbel Jong-Hwa Ahn Hyo-Soo Kim Myung Ho Jeong Yaling Han Sidney C.Smith Jr. Junbo Ge 2019Science Bulletin2019,64,3:12
10Analysis of the risk factors for severity in post endoscopic retrograde cholangiopancreatography pancreatitis: The indication of prophylactic treatments显示文摘AIM To determine the risk factors of severe post endoscopic retrograde cholangiopancreatography pancreatitis(s PEP) and clarify the indication of prophylactic treatments.METHODS At our hospital, endoscopic retrograde cholangiopancreatography(ERCP) was performed on 1507 patients from May 2012 to December 2015. Of these patients, we enrolled all 121 patients that were diagnosed with post endoscopic retrograde PEP. Fourteen of 121 patients diagnosed as s PEP were analyzed.RESULTS Forty-one patients had contrast media remaining in the pancreatic duct after completion of ERCP. Seventy-one patients had abdominal pain within three hours after ERCP. These were significant differences for s PEP(P < 0.05). The median of Body mass index, the median time for ERCP, the median serum amylase level of the next day, past histories including drinking and smoking, past history of pancreatitis, sphincter of Oddi dysfunction, whether emergency or not, expertise of ERCP procedure, diverticulum nearby Vater papilla, whether there was sphincterotomy or papillary balloon dilation, pancreatic duct cannulation, use of intraductal ultrasonography enforcement, and transpapillary biopsies had no significant differences with s PEP.CONCLUSION Contrast media remaining in the pancreatic duct and the appearance of abdominal pain within three hours after ERCP were risk factors of s PEP.Hiroshi Matsubara Fumihiro Urano Yuki Kinoshita Shozo Okamura Hiroki Kawashima Hidemi Goto Yoshiki Hirooka 2017World Journal of Gastrointestinal Endoscopy2017,9,4:12
11Endoscopic ultrasound-guided fine needle aspiration in the differentiation of type 1 and type 2 autoimmune pancreatitis显示文摘AIM:To investigate the usefulness of endoscopic ultrasound-guided fine needle aspiration(EUS-FNA) in the differentiation of autoimmune pancreatitis(AIP).METHODS:We retrospectively reviewed 47 of 56 AIP patients who underwent EUS-FNA and met the Asian diagnostic criteria.On 47 EUS-FNA specimens,we evaluated the presence of adequate material and characteristic features of lymphoplasmacytic sclerosing pancreatitis(LPSP) and idiopathic duct-centric pancreatitis(IDCP) mentioned in the International Consensus Diagnostic Criteria and examined if these findings make a contribution to the differential diagnosis of type 1 and type 2 AIP.A disposable 22-gauge needle was used for EUS-FNA.RESULTS:Adequate specimens including pancreatic tissue for differentiating AIP from cancer were obtained from 43 of 47 patients who underwent EUSFNA.EUS-FNA was performed from the pancreatic head in 21 cases,which is known to be technically difficult when performed by core biopsy;there was no significant difference in the results compared with pancreatic body-tail.Nine of 47 patients met level 1 findings of LPSP and 5 patients met level 2 findings of LPSP.No one met level 1 findings of IDCP,but 3 patients met level 2 findings of IDCP.Of 10 seronegative cases,2 cases were diagnosed with 'definitive type 1 AIP',and 3 cases were diagnosed with 'probable type 2 AIP' when considering both the level 2 histological findings and response to steroids.CONCLUSION:EUS-FNA is useful in the differentiation of type 1 and type 2 AIP,particularly in seronegative cases.Takuya Ishikawa Akihiro Itoh Hiroki Kawashima Eizaburo Ohno Hirosh Matsubara Yuya Itoh Yosuke Nakamura Takeshi Hiramatsu Masanao Nakamura Ryoji Miyahara Naoki Ohmiya Hidemi Goto Yoshiki Hirooka 2012World Journal of Gastroenterology2012,18,29:8
12BRIEF ARTICLE New reduced volume preparation regimen in colon capsule endoscopy显示文摘AIM:To evaluate the effectiveness of our proposed bowel preparation method for colon capsule endoscopy.METHODS:A pilot,multicenter,randomized controlled trial compared our proposed 'reduced volume method'(group A) with the 'conventional volume method'(group B) preparation regimens.Group A did not drink polyethylene glycol electrolyte lavage solution(PEGELS) the day before the capsule procedure,while group B drank 2 L.During the procedure day,groups A and B drank 2 L and 1 L of PEG-ELS,respectively,and swallowed the colon capsule(PillCam COLON capsule).Two hours later the first booster of 100 g magnesium citrate mixed with 900 mL water was administered to both groups,and the second booster was administered six hours post capsule ingestion as long as the capsule had not been excreted by that time.Capsule videos were reviewed for grading of cleansing level,RESULTS:Sixty-four subjects were enrolled,with results from 60 analyzed.Groups A and B included 31 and 29 subjects,respectively.Twenty-nine(94%) subjects in group A and 25(86%) subjects in group B had adequate bowel preparation(ns).Twenty-two(71%) of the 31 subjects in group A excreted the capsule within its battery life compared to 16(55%) of the 29 subjects in group B(ns).Of the remaining 22 subjects whose capsules were not excreted within the battery life,all of the capsules reached the left side colon before they stopped functioning.A single adverse event was reported in one subject who had mild symptoms of nausea and vomiting one hour after starting to drink PEG-ELS,due to ingesting the PEG-ELS faster than recommended.CONCLUSION:Our proposed reduced volume bowel preparation method for colon capsule without PEG-ELS during the days before the procedure was as effective as the conventional volume method.Yasuo Kakugawa Yutaka Saito Shoichi Saito Kenji Watanabe Naoki Ohmiya Mitsuyuki Murano Shiro Oka Tetsuo Arakawa Hidemi Goto Kazuhide Higuchi Shinji Tanaka Hideki Ishikawa Hisao Tajiri 2012World Journal of Gastroenterology2012,18,17:8
13Characteristic endoscopic findings and risk factors for cytomegalovirus-associated colitis in patients with active ulcerative colitis显示文摘AIM: To identify characteristic endoscopic findings and risk factors for cytomegalovirus(CMV)-associated colitis in patients with active ulcerative colitis(UC).METHODS: A total of 149 UC patients admitted to the Department of Gastroenterology, Nagoya University Hospital, from January 2004 to December 2013 with exacerbation of UC symptoms were enrolled in this retrospective study. All medical records, including colonoscopy results, were reviewed. CMV infection was determined by the presence of CMV antigen, CMV inclusion bodies in biopsy specimens, or positive specific immunohistochemical staining for CMV. Multivariate analysis was used to identify independent risk factors for CMV colitis.RESULTS: Multivariate analysis indicated independent associations with the extent of disease(pancolitis) anduse of > 400 mg corticosteroids for the previous 4 wk. In contrast, no association was seen with sex, age at UC diagnosis, immunomodulator use, or infliximab use. Punched-out ulceration was also significantly associated with CMV infection in patients with active UC(odds ratio = 12.672, 95%CI: 4.210-38.143).CONCLUSION: Identification of a total corticosteroid dose > 400 mg for 4 wk, extensive colitis and a specific endoscopic finding of punched-out ulcer might facilitate the more rapid diagnosis and timely initiation of antiviral therapy for CMV-associated colitis in patients with active UC.Yutaka Hirayama Takafumi Ando Yoshiki Hirooka Osamu Watanabe Ryoji Miyahara Masanao Nakamura Takeshi Yamamura Hidemi Goto 2016World Journal of Gastrointestinal Endoscopy2016,8,6:8
14Use of color Doppler ultrasonography in the diagnosis of anomalous connection in pancreatobiliary disease显示文摘AIM: To estimate the detectability of anomalous connection in pancreatobiliary disease (ACPBD) cases, measuring gallbladder wall blood flow (GWBF).METHODS: In the retrospective study, we enrolled 42subjects with gallbladder wall thickening. GWBF velocity was determined as an average value of the peak velocity of color signals on the gallbladder wall, three times in each case. Based on the findings on endoscopic ultrasonography (EUS) or endoscopic retrograde cholangiopancreatography (ERCP), the 42 subjects were divided into 11 cases with ACPBD and 31 cases without ACPBD. In the prospective study, the subjects were 92 cases with gallbladder wall thickening. Using the cut-off level of the flow velocity obtained in the retrospective study, the usefulness of measuring GWBF velocity in diagnosing ACPBD was evaluated.RESULTS: In the retrospective study, imaging of GWBF was obtained in 40 of the 42 subjects. The mean GWBF velocity of the ACPBD cases was 29.4±3.9 cm/s(mean±SD), which was significantly different (P<0.0001;95% CI 5.48-13.2) from that of the without ACPBD cases(20.1±5.9 cm/s). Based on this result, we prepared a receiver operating characteristic curve, and the cut-off level appropriate for diagnosing ACPBD was estimated to be 25 cm/s. In the prospective study, GWBF was detected in 86 of the 92 subjects. Based on the EUS or ERCP findings, the 92 subjects were divided into 15 cases with ACPBD and 77 cases without ACPBD. When a cut-off level of 25 cm/s was employed, ACPBD could be diagnosed with a sensitivity of 87.0% (13/15) and a specificity of87.3% (62/71).CONCLUSION: Measurement of GWBF velocity, which is less invasive and provides objective values, is very useful for diagnosing ACPBD prior to the development of malignant tumors in cases with gallbladder wall thickening.Hiroki Kawashima Yoshiki Hirooka Akihiro Itoh Senju Hashimoto Terutomo Itoh Kazuo Hara Akira Kanamori Naoki Ohmiya Yasumasa Niwa Hidemi Goto 2005World Journal of Gastroenterology2005,11,7:7
15Early effects of oral administration of omeprazole and roxatidine on intragastric pH显示文摘Objective:The ideal medication for the treatment of acid-related diseases,e.g.,peptic ulcers,stress-related gastric bleeding,functional dyspepsia,and gastroesophageal reflux disease,should have a rapid onset of action to promote hemostasis and relieve the symptoms.The aim of our study was to investigate the inhibitory effects on gastric acid secretion of a single oral administration of a proton pump inhibitor,omeprazole 20 mg,and an H2-receptor antagonist,roxatidine 75 mg.Methods:Ten Helicobacter pylori-negative male subjects participated in this randomized,two-way crossover study.Intragastric pH was monitored continuously for 6 h after single oral administration of omeprazole 20 mg and roxatidine 75 mg.Each administration was separated by a 7-d washout period.Results:During the 6-h study period,the average pH after administration of roxatidine was higher than that after administration of omeprazole(median:4.45 vs.2.65;P=0.0367).Also during the 6-h study period,a longer duration of maintenance at pH above 2,5,and 6 was observed after administration of roxatidine 75 mg than after administration of omeprazole 20 mg(median:90.6% vs.55.2%,P=0.0284;43.7% vs.10.6%,P=0.0125;40.3% vs.3.3%,P=0.0125;respectively).Conclusions:In Helicobacter pylori-negative healthy male subjects,oral administration of roxatidine 75 mg increased the intragastric pH more rapidly than that of omeprazole 20 mg.Hiroshi IIDA Shingo KATO Yusuke SEKINO Eiji SAKAI Takashi UCHIYAMA Hiroki ENDO Kunihiro HOSONO Yasunari SAKAMOTO Koji FUJITA Masato YONEDA Tomoko KOIDE Hirokazu TAKAHASHI Chikako TOKORO Ayumu GOTO Yasunobu ABE Noritoshi KOBAYASHI Kensuke KUBOTA Eiji GOTOH Shin MAEDA Atsushi NAKAJIMA Masahiko INAMORI 2012Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2012,13,1:6
16Inducible nitric oxide synthase polymorphism is associated with the increased risk of differentiated gastric cancer in a Japanese population显示文摘AIM: To examine the association of inducible nitric oxide synthase (iNOS) C150T polymorphism with gastric cancer, as well as with gastric atrophy and H pylori seropositivity. METHODS: A single nucleotide polymorphism of iNOS C150T was examined for 454 Japanese health checkup examinees (126 males and 328 females) aged 35 to 85 years without a history of cancer and 202 gastric cancer patients (134 males and 68 females) aged 33 to 94 years with pathologically confirmed diagnosis of gastric adenocarcinoma. RESULTS: The iNOS C150T polymorphism was not associated with gastric atrophy or with H pylori seropositivity. The odds ratio (OR) of the C/T + T/T for gastric cancer was increased without statistical significance (OR=1.19, 95% confidence interval (CI): 0.68-2.08). In the differentiated subgroup (n = 113), however, the OR of the C/T genotype for gastric cancer was significant (OR = 2.02, 95% CI: 1.04-3.92) relative to the C/C genotype. In addition, considering the location of gastric cancer (n = 105), there were significant differences between the controls and non-cardia group with the OR of 2.13 (95% CI: 1.08-4.18) for C/T and 1.94 (95% CI: 1.00-3.78) for C/T + T/T. CONCLUSION: The iNOS C150T polymorphism is associated with the risk of H pylori-related gastric cancerin a Japanese population. This polymorphism may play an important role in increasing the risk of gastric cancer in Asian countires with the highest rates of gastric cancer.Yasuyuki Goto Takafumi Ando Mariko Naito Hidemi Goto Nobuyuki Hamajima 2006World Journal of Gastroenterology2006,12,39:6

19In vivo histological diagnosis for gastric cancer using endocytoscopy显示文摘AIM To examine usefulness of virtual biopsy using endocytoscopy by comparing the in vivo endocytoscopic and histopathological images of gastric cancers.METHODS Endocytoscopy was performed in 30 patients with early gastric cancer. Of these, 26 patients showed well differentiated adenocarcinomas, while 4 patients showed poorly differentiated adenocarcinomas(including one signet ring cell carcinoma). Cancerous and non-cancerous areas were observed after double staining with 0.05% crystal violet and 0.1% methylene blue. The endocytoscopic images obtained were evaluated by an expert endoscopist and an expert pathologist without knowledge of patient clinical data, and endocytoscopic and histopathological diagnoses were compared.RESULTS The endocytoscopic images of the cancerous area were assessed as evaluable in 25(83.3%) and 27(90%) patients by endoscopist A and pathologist B, respectively, and those of the non-cancerous area as evaluable in 28(93.3%) and 23(76.7%) patients by the endoscopist and pathologist, respectively. The sensitivity, specificity, and diagnostic accuracy of gastric cancer diagnosis using evaluable endocytoscopic images were 88.0% and 92.9%, and 90.6% by endoscopist A, and 88.9% and 91.3%, and 90.0% by pathologist B, respectively. Evaluation of the diagnostic concordance rate between the endoscopist and the pathologist by inter-observer agreement calculation revealed no significant difference between the two observers. The inter-observer agreement(κ-value) for endocytoscopic diagnosis was 0.745. CONCLUSION Endocytoscopy is useful for the differentiation of cancerous from non-cancerous gastric mucosa, making it a promising tool for virtual biopsy.Issei Tsurudome Ryoji Miyahara Kohei Funasaka Kazuhiro Furukawa Masanobu Matsushita Takeshi Yamamura Takuya Ishikawa Eizaburo Ohno Masanao Nakamura Hiroki Kawashima Osamu Watanabe Masato Nakaguro Akira Satou Yoshiki Hirooka Hidemi Goto 2017World Journal of Gastroenterology2017,23,37:5
20高可靠性IGBT模块封装的设计显示文摘本文给出了当前的IGBT模块封装设计的原则,重点是封装结构和可靠性之间的关系,特别是温度循环性能。复杂的IGBT模块内部含有不同的材料。因为不同的热膨胀系数,层间介面处的物理损坏会伴随着一系列温度循环而不断累积。IGBT模块的寿命周期主要依赖于其材料的组合和结构设计上。作为一种尝试,本文针对未来IGBT在较高的运行温度下的可能性,谈到了当前的热优化设计和键合技术研究。Yoshitaka Nishimura Kazunaga Oonishi Fumihiko Momose Tomoaki Goto 袁海斌(译) 2010电力电子2010,,4:5
