| 1 | Safety trial of high-intensity focused ultrasound therapy for pancreatic cancer显示文摘AIM:To evaluate the safety and clinical application of high-intensity focused ultrasound(HIFU)therapy for unresectable pancreatic cancer(PC).METHODS:Thirty PC patients(16 cases in stage III and 14 cases in stage IV)with visualized pancreatic tumors were admitted for HIFU therapy as an optional local therapy in addition to systemic chemotherapy or chemoradiotherapy.Informed consent was obtained.This study began at the end of 2008 and was approved by the ethics committee of our hospital[Institutional Review Board(IRB):890].The HIFU device used was the FEP-BY02(Yuande Bio-Medical Engineering,Beijing,China).RESULTS:The mean tumor size after HIFU therapy changed to 30.9±1.7 mm from 31.7±1.7 mm at pre-therapy.There were no significant changes in tumor size,mean number of treatment sessions(2.7±0.1 mm),or mean total treatment time(2.4±0.1 h).The rate of symptom relief effect was 66.7%.The effectiveness of primary lesion treatment was as follows:complete response,0;partial response,4;stable disease,22;progressive disease,4.Treatment after HIFU therapy included 2 operations,24 chemotherapy treatments,and 4 best supportive care treatments.Adverse events occurred in 10%of cases,namely pseudocyst formation in 2 cases and mild pancreatitis development in 1.However,no severe adverse events occurred in this study.CONCLUSION:We suggest that HIFU therapy is safe and has the potential to be a new method of combination therapy for PC. | Atsushi Sofuni Fuminori Moriyasu Takatomo Sano Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Kentaro Ishii Syujiro Tsuji Nobuhito Ikeuchi Reina Tanaka Junko Umeda Ryosuke Tonozuka Mitsuyoshi Honjo Shuntaro Mukai Mitsuru Fujita Takao Itoi | 2014 | World Journal of Gastroenterology2014,20,28: | 12 |
| 2 | New pyrometallurgical process of EAF dust treatment with CaO addition显示文摘The non-carbothermic zinc pyrometallurgical processing of electric arc furnace(EAF) dust was investigated on a laboratory scale. The main objective of this process was to convert highly stable zinc ferrite(Zn Fe2O4), which accounts for more than half of total zinc in the EAF dust, into Zn O and Ca2Fe2O5 by Ca O addition. The EAF dust was mixed with Ca O powder in various ratios, pressed into pellets, and heated in a muffle furnace in air at temperatures ranging from 700 to 1100°C for a predetermined holding time. All Zn Fe2O4 was transformed into Zn O and Ca2Fe2O5 at a minimum temperature of 900°C within 1 h when sufficient Ca O to achieve a Ca/Fe molar ratio of 1.1 was added. However, at higher temperatures, excess Ca O beyond the stoichiometric ratio was required because it was consumed by reactions leading to the formation of compounds other than Zn Fe2O4. The evaporation of halides and heavy metals in the EAF dust was also studied. These components could be preferentially volatilized into the gas phase at 1100°C when Ca O was added. | Romchat Chairaksa-Fujimoto Yosuke Inoue Naoyoshi Umeda Satoshi Itoh Tetsuya Nagasaka | 2015 | International Journal of Minerals,Metallurgy and Materials2015,22,8: | 7 |

| 4 | Cloning and sequence characteristics of the genomic gene of a rice metallothionein显示文摘Northern blot analysis showed that a metallothionein gene, ricMT is expressed strongly in the stem of rice with an expression level that could be more than 100-fold stronger than in leaf blades. The results suggest that the 5’ upstream region flanking the coding sequence of the ricMT may contain a fairly strong promoter To elucidatr its regulation and promoter structure, the genomic clones of ricMT were screened out from a rice genomic library and a fragment of about 4084 bp was sequenced. The fragment included a 5’ upstream region of ca. 2970 bp, a transcription region of ca. 690 bp and a 3’ downstream region of ca. 420 bp. Computer analysis of the sequence homology showed that the 5’ upstream region included a putative TATA box, a putative CAAT box, and a typical metal-responsive element TGCGCGCG. The results will promote further understanding of the mechanisms of gene regulation and metal response of plant metallothionein proteins. | YU Lihua, LIU Jinyuan, Masaaki Umeda, Hirofumi Uchimiya & ZHAO Nanming Department of Biological Sciences and Biotechnology, State Key Laboratory of Biomembrane and Membrane Biotechnology, Beijing 100084, China Institute of Molecular and Cellular Bioscie | 2000 | Chinese Science Bulletin2000,45,2: | 4 |
| 5 | Prognosis of cancer with branch duct type IPMN of the pancreas显示文摘AIM:To examine the coexistence of metachronous and synchronous cancer in branch duct intraductal papillary mucinous neoplasms of the pancreas (IPMN).METHODS: We reviewed the records of 145 patients with branch duct IPMN between January 1991 and April 2008 and assessed the relationship between IPMN and intraor extra-pancreatic carcinoma and the outcome of IPMN.RESULTS: The mean observation period was 55.9 ± 45.3 mo. Among the 145 patients, the frequency of extra-pancreatic cancer was 29.0%. The frequency of gastric cancer, colon cancer, breast cancer, and pan-creatic cancer were 25.5%, 15.7%, 13.7%, and 9.8%, respectively. Twenty (13.8%) of the patients died. The cause of death was extra-pancreatic carcinoma in 40%,pancreatic cancer in 25%, IPMN per se in 20%, and benign disease in 15% of the patients.CONCLUSION: The prognosis for IPMN depends not on the IPMN per se, but on the presence of intraor extra-pancreatic cancer. | Nobuhito Ikeuchi Takao Itoi Atsushi Sofuni Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Kentaro Ishii Shujiro Tsuji Junko Umeda Fuminori Moriyasu Akihiko Tsuchida Kazuhiko Kasuya | 2010 | World Journal of Gastroenterology2010,16,15: | 3 |
| 6 | CD14 upregulation as a distinct feature of non-alcoholic fatty liver disease after pancreatoduodenectomy显示文摘AIM:To investigate the pathogenesis of non-alcoholic fatty liver disease(NAFLD)after pancreatoduodenectomy(PD).METHODS:A cohort of 82 patients who underwent PD at Okayama University Hospital between 2003 and 2009 was enrolled and the clinicopathological features were compared between patients with and without NAFLD after PD.Computed tomography(CT)images were evaluated every 6 mo after PD for follow-up.Hepatic steatosis was diagnosed on CT when hepatic attenuation values were 40 Hounsfield units.Liver biopsy was performed for 4 of 30 patients with NAFLD after PD who consented to undergo biopsies.To compare NAFLD after PD with NAFLD associated with metabolic syndrome,liver samples were obtained from 10 patients with NAFLD associated with metabolic syndrome [fatty liver,n = 5;non-alcoholic steatohepatitis(NASH),n = 5] by percutaneous ultrasonography-guided liver biopsy.Double-fluorescence immunohistochemistry was applied to examine CD14 expression as a marker of lipopolysaccharide(LPS)-sensitized macrophage cells(Kupffer cells)in liver biopsy specimens.RESULTS:The incidence of postoperative NAFLD was 36.6%(30/82).Univariate analysis identified cancer of the pancreatic head,sex,diameter of the main pancreatic duct,and dissection of the nerve plexus as factors associated with the development of NAFLD after PD.Those patients who developed NAFLD after PD demonstrated significantly decreased levels of serum albumin,total protein,cholesterol and triglycerides compared to patients without NAFLD after PD,but no glucose intolerance or insulin resistance.Liver biopsy was performed in four patients with NAFLD after PD.All four patients showed moderate-to-severe steatosis and NASH was diagnosed in two.Numbers of cells positive for CD68(a marker of Kupffer cells)and CD14(a marker of LPSsensitized Kupffer cells)were counted in all biopsy specimens.The number of CD68+ cells in specimens of NAFLD after PD was significantly increased from that in specimens of NAFLD associated with metabolic syndrome specimens,which indicated the presence of significantly more Kupffer cells in NAFLD after PD than in NAFLD associated with metabolic syndrome.Similarly,more CD14+ cells,namely,LPS-sensitized Kupffer cells,were observed in NAFLD after PD than in NAFLD associated with metabolic syndrome.Regarding NASH,more CD68+ cells and CD14+ cells were observed in NASH after PD specimens than in NASH associated with metabolic syndrome.This showed that more Kupffer cells and more LPS-sensitized Kupffer cells were present in NASH after PD than in NASH associated with metabolic syndrome.These observations suggest that after PD,Kupffer cells and LPS-sensitized Kupffer cells were significantly upregulated,not only in NASH,but also in simple fatty liver.CONCLUSION:NAFLD after PD is characterized by both malnutrition and the up-regulation of CD14 on Kupffer cells.Gut-derived endotoxin appears central to the development of NAFLD after PD. | Daisuke Satoh Takahito Yagi Takeshi Nagasaka Susumu Shinoura Yuzo Umeda Ryuichi Yoshida Masashi Utsumi Takehiro Tanaka Hiroshi Sadamori Toshiyoshi Fujiwara | 2013 | World Journal of Hepatology2013,5,4: | 3 |
| 7 | Sulforaphane-rich broccoli sprout extract improves hepatic abnormalities in male subjects显示文摘AIM: To evaluate effects of dietary supplementation of sulforaphane(SF)-rich broccoli sprout(BS) extract on hepatic abnormalities in Japanese male participants.METHODS: In a randomized,placebo-controlled,double blind trial,male participants with fatty liver received either BS capsules containing glucoraphanin [GR; a precursor of SF(n = 24)] or placebo(n = 28) for 2 mo. Liver function markers,serum levels of aspartate and alanine aminotransferases(AST and ALT,respectively) and γ-glutamyl transpeptidase(γ-GTP) and an oxidative stress marker,urinary levels of 8-hydroxydeoxyguanosine(8-OHd G),were measured and compared in participants before and after the trial period. In an animal model,chronic liver failure was induced in Sprague-Dawley rats by successive intraperitoneal injection with N-nitrosodimethylamine(NDMA) for 4 wk. Concomitantly,rats received AIN-76 diets supplemented with or without BS extract. Thereafter,rats were sacrificed,and their sera and livers were collected to measure serum liver function markers and hepatic levels of thiobarbituric acid reactive substances(TBARS) levels and hepatic glutathione S-transferase(GST) activity,a prototypical phase 2 antioxidant enzyme.RESULTS: Dietary supplementation with BS extract containing SF precursor GR for 2 mo significantly decreased serum levels of liver function markers,ALT [median(interquartile range),before: 54.0(34.5-79.0) vs after supplementation: 48.5(33.3-65.3) IU/L,P < 0.05] and γ-GTP [before: 51.5(40.8-91.3) vs after: 50.0(37.8-85.3) IU/L,P < 0.05],as well as the alkali phosphatase activity. Placebo showed no significant effects on the markers. The urinary level of 8-OHd G,an established oxidative stress marker,was significantly reduced in participants who had received BS capsules but not the placebo [before: 6.66(5.51-9.03) vs after: 5.49(4.89-6.66) ng/mg-creatinine,P < 0.05]. The reduction of urinary 8-OHd G was significantly correlated with decreased levels of both ALT and γ-GTP [?8-OHd G and ?ALT: Spearman r(r) 0.514 and P = 0.012,?8-OHd G and ?γ-GTP: r = 0.496 and P = 0.016]. Intake of BS extract prevented NDMA-induced chronic liver failure in rats,which was attributable to the suppression of the increase in TBARS through induction of hepatic phase 2 antioxidant enzymes including hepatic GST(86.6 ± 95.2 vs 107.8 ± 7.7 IU/g,P < 0.01).CONCLUSION: Dietary supplementation with BS extract containing the SF precursor GR is likely to be highly effective in improving liver function through reduction of oxidative stress. | Masahiro Kikuchi Yusuke Ushida Hirokazu Shiozawa Rumiko Umeda Kota Tsuruya Yudai Aoki Hiroyuki Suganuma Yasuhiro Nishizaki | 2015 | World Journal of Gastroenterology2015,21,43: | 3 |

| 9 | 自由锻Ti-Ni形状记忆合金的显微组织和超弹性(英文)显示文摘采用放电等离子烧结(SPS)法将元素钛粉和镍粉制备成Ti-51%Ni形状记忆合金(SMAs)。研究目的是采用自由锻二次加工以提高SPS合金的性能。对自由锻前后合金的显微组织、相变温度和超弹性进行比较。结果表明,自由锻可以显著提高Ti-Ni形状记忆合金的拉伸强度和形状记忆性能,自由锻后合金的韧性从6.8%提高到了9.2%,超弹性的应变范围从5%增加到7.5%,应变恢复速率从72%提高到92%。Ti-51%Ni合金显微组织中含有立方奥氏体相(B2)基体、单斜马氏体相(B19′)、第二相(Ti_3Ni_4,Ti_2Ni和TiNi_3)和氧化物相(Ti_4Ni_2O,Ti_3O_5)。自由锻后再经500°C时效处理的最终样品的马氏体相变温度向高温方向偏移,这是由于Ti_3Ni_4相(透射电镜下可以观察到)的析出而导致基体中Ni含量的减少。总之,自由锻可以提高Ti-51%Ni形状记忆合金的超弹性和力学性能。 | Abdollah BAHADOR Esah HAMZAH Katsuyoshi KONDOH Tuty ASMA ABUBAKAR Farazila YUSOF Junko UMEDA Safaa N.SAUD Mustafa K.IBRAHIM | 2018 | Transactions of Nonferrous Metals Society of China2018,28,3: | 2 |
| 10 | Observation of mitochondrial activity based on temporal and spatial pH variations measured by near-field fluorescent ratiometry显示文摘A novel method combining dual wavelength fluorescent ratiometry with scanning near-field optical microscopy (SNOM) is proposed and developed to measure the concentration and distribution of protons in the vicinity of biological samples. This method involves immersing mitochondria in a pH-sensitive fluorescent dye solution instead of injecting the dye into the surface of the mitochondrial membrane. It uses a dual emission pH-sensitive dye and SNOM with a thermally pulled and metal-coated optical fiber probe to improve the spatial resolution. The time dependence of the fluorescence intensity ratio (FIR) under acid addition and the response of mitochondria to nutritional supplementation were studied by using this method. Activation of mitochondria and a distance-dependent delay in the FIR response were observed. The results confirmed that mitochondrial activity could be observed by using this method. | LI YongBo SHIONHARA Ryosuke IWAMI Kentaro OHTA Yoshihiro UMEDA Norihiro | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,12: | 2 |

| 13 | Protective effect of Irsogladine on monochloramineinduced gastric mucosallesions in rats:a comparative study with rebamipide显示文摘AIM To examine the effect of irsogladine, a novel antiulcer drug, on the mucosal ulcerogenic response to monochloramine (NH 2Cl) in rat stomach, in comparison with rebamipide, another antiulcer drug with cytoprotective activity. METHODS AND RESULTS Oral administration of NH 2Cl (120*!mM) produced severe hemorrhagic lesions in unanesthetized rat stomachs. Both irsogladine ( 1*!mg/*!kg - 10*!mg/*!kg , po ) and rebamipide ( 30*!mg/*!kg - 100*!mg/*!kg , po ) dose dependently prevented the development of these lesions in response to NH 2Cl, the effect of irsogladine was significant at 3*!mg/*!kg or greater, and that of rebamipide only at 100*!mg/*!kg . The protective effect of irsogladine on NH 2Cl induced gastric lesions was significantly reduced by N G nitro L arginine methyl ester (L NAME) but not by indomethacin, while that of rebamipide was significantly mitigated by indomethacin but not by L NAME. Topical application of NH 2Cl (20*!mM) caused a marked reduction of potential difference (PD) in ex vivo stomachs. This PD reduction was not affected by mucosal application of irsogladine, but significantly prevented by rebamipide. The mucosal exposure to NH 4OH (120*!mM) also caused a marked PD reduction in the ischemic stomach (bleeding from the carotid artery), resulting in gastric lesions. These ulcerogenic and PD responses caused by NH 4OH plus ischemia were also significantly mitigated by rebamipide, in an indomethacin sensitive manner, while irsogladine potently prevented such lesions without affecting the PD response, in a L NAME sensitive manner. CONCLUSION These results suggest that ① NH 2Cl generated either exogenously or endogenously damages the gastric mucosa, ② both irsogladine and rebamipide protect the stomach against injury caused by NH 2Cl, and ③ the mechanism underlying the protective action of irsogladine is partly mediated by endogenous nitric oxide, while that of rebamipide is in part mediated by endogenous prostaglandins. | H Yamamoto, M Umeda, H Mizoguchi, S Kato and K Takeuchi | 1999 | World Journal of Gastroenterology1999,5,6: | 2 |
