| 1 | Glycer-AGEs-RAGE signaling enhances the angiogenic potential of hepatocellular carcinoma by upregulating VEGF expression显示文摘AIM:To investigate the effect of glyceraldehyde-derived advanced glycation end-products(Glycer-AGEs) on hepatocellular carcinoma(HCC)cells.METHODS:Two HCC cell lines(Hep3B and HepG2 cells)and human umbilical vein endothelial cells(HUVEC)were used.Cell viability was determined using the WST-8 assay.Western blotting,enzyme linked immunosorbent assay,and real-time reverse transcriptionpolymerase chain reactions were used to detect protein and mRNA.Angiogenesis was evaluated by assessing the proliferation,migration,and tube formation of HUVEC.RESULTS:The receptor for AGEs(RAGE)protein was detected in Hep3B and HepG2 cells.HepG2 cells werenot affected by the addition of Glycer-AGEs.GlycerAGEs markedly increased vascular endothelial growth factor(VEGF)mRNA and protein expression,which is one of the most potent angiogenic factors.Compared with the control unglycated bovine serum albumin(BSA) treatment,VEGF mRNA expression levels induced by the Glycer-AGEs treatment were 1.00±0.10 vs 1.92 ±0.09(P<0.01).Similarly,protein expression levels induced by the Glycer-AGEs treatment were 1.63±0.04 ng/mL vs 2.28±0.17 ng/mL for the 24 h treatment and 3.36±0.10 ng/mL vs 4.79±0.31 ng/mL for the 48 h treatment,respectively(P<0.01).Furthermore,compared with the effect of the control unglycated BSA-treated conditioned medium,the Glycer-AGEstreated conditioned medium significantly increased the proliferation,migration,and tube formation of HUVEC,with values of 122.4%±9.0%vs 144.5%±11.3%for cell viability,4.29±1.53 vs 6.78±1.84 for migration indices,and 71.0±7.5 vs 112.4±8.0 for the number of branching points,respectively(P<0.01).CONCLUSION:These results suggest that Glycer-AGEs-RAGE signaling enhances the angiogenic potential of HCC cells by upregulating VEGF expression. | Junichi Takino Shoichi Yamagishi Masayoshi Takeuchi | 2012 | World Journal of Gastroenterology2012，18，15： | 27 |
| 2 | Pathogenesis of NSAID-induced gastric damage:Importance of cyclooxygenase inhibition and gastric hypermotility显示文摘This article reviews the pathogenic mechanism of nonsteroidal anti-inflammatory drug(NSAID)-induced gastric damage,focusing on the relation between cyclooxygenase(COX) inhibition and various functional events.NSAIDs,such as indomethacin,at a dose that inhibits prostaglandin(PG) production,enhance gastric motility,resulting in an increase in mucosal permeability,neutrophil infiltration and oxyradical production,and eventually producing gastric lesions.These lesions are prevented by pretreatment with PGE 2 and antisecretory drugs,and also via an atropine-sensitive mechanism,not related to antisecretory action.Although neither rofecoxib(a selective COX-2 inhibitor) nor SC-560(a selective COX-1 inhibitor) alone damages the stomach,the combined administration of these drugs provokes gastric lesions.SC-560,but not rofecoxib,decreases prostaglandin E 2(PGE 2) production and causes gastric hypermotility and an increase in mucosal permeability.COX-2 mRNA is expressed in the stomach after administration of indomethacin and SC-560 but not rofecoxib.The up-regulation of indomethacin-induced COX-2 expression is prevented by atropine at a dose that inhibits gastric hypermotility.In addition,selective COX-2 inhibitors have deleterious influences on the stomach when COX-2 is overexpressed under various conditions,including adrenalectomy,arthritis,and Helicobacter pylori-infection.In summary,gastric hypermotility plays a primary role in the pathogenesis of NSAID-induced gastric damage,and the response,causally related with PG deficiency due to COX-1 inhibition,occurs prior to other pathogenic events such as increased mucosal permeability;and the ulcerogenic properties of NSAIDs require the inhibition of both COX-1 and COX-2,the inhibition of COX-1 upregulates COX-2 expression in association with gastric hypermotility,and PGs produced by COX-2 counteract the deleterious effect of COX-1 inhibition. | Koji Takeuchi | 2012 | World Journal of Gastroenterology2012，18，18： | 25 |

| 4 | Machine learning modeling of superconducting critical temperature显示文摘Superconductivity has been the focus of enormous research effort since its discovery more than a century ago.Yet,some features of this unique phenomenon remain poorly understood;prime among these is the connection between superconductivity and chemical/structural properties of materials.To bridge the gap,several machine learning schemes are developed herein to model the critical temperatures(T_(c))of the 12,000+known superconductors available via the SuperCon database.Materials are first divided into two classes based on their T_(c) values,above and below 10 K,and a classification model predicting this label is trained.The model uses coarse-grained features based only on the chemical compositions.It shows strong predictive power,with out-of-sample accuracy of about 92%.Separate regression models are developed to predict the values of T_(c) for cuprate,iron-based,and low-T_(c) compounds.These models also demonstrate good performance,with learned predictors offering potential insights into the mechanisms behind superconductivity in different families of materials.To improve the accuracy and interpretability of these models,new features are incorporated using materials data from the AFLOW Online Repositories.Finally,the classification and regression models are combined into a single-integrated pipeline and employed to search the entire Inorganic Crystallographic Structure Database(ICSD)for potential new superconductors.We identify>30 non-cuprate and non-iron-based oxides as candidate materials. | Valentin Stanev Corey Oses A.Gilad Kusne Efrain Rodriguez Johnpierre Paglione Stefano Curtarolo Ichiro Takeuchi | 2018 | npj Computational Materials2018，，1： | 21 |
| 5 | Feasibility of cold snare polypectomy in Japan: A pilot study显示文摘AIM: To investigate the feasibility of cold snare polypectomy(CSP) in Japan.METHODS: The outcomes of 234 non-pedunculated polyps smaller than 10 mm in 61 patients who underwent CSP in a Japanese referral center were retrospectively analyzed. The cold snare polypectomies were performed by nine endoscopists with no prior experience in CSP using an electrosurgical snare without electrocautery.RESULTS: CSPs were completed for 232 of the 234 polyps. Two(0.9%) polyps could not be removed without electrocautery. Immediate postpolypectomy bleeding requiring endoscopic hemostasis occurred in eight lesions(3.4%; 95%CI: 1.1%-5.8%), but all were easily managed. The incidence of immediate bleeding after CSP for small polyps(6-9 mm) was significantly higher than that of diminutive polyps(≤ 5 mm; 15% vs 1%, respectively). Three(5%) patients complained of minor bleeding after the procedure but required no intervention. The incidence of delayed bleeding requiringendoscopic intervention was 0.0%(95%CI: 0.0%-1.7%). In total, 12% of the resected lesions could not be retrieved for pathological examination. Tumor involvement in the lateral margin could not be histologically assessed in 70(40%) lesions.CONCLUSION: CSP is feasible in Japan. However, immediate bleeding, retrieval failure and uncertain assessment of the lateral tumor margin should not be underestimated. Careful endoscopic diagnosis before and evaluation of the tumor residue after CSP are recommended when implementing CSP in Japan. | Yoji Takeuchi Takeshi Yamashina Noriko Matsuura Takashi Ito Mototsugu Fujii Kengo Nagai Fumi Matsui Tomofumi Akasaka Noboru Hanaoka Koji Higashino Hiroyasu Iishi Ryu Ishihara Henrik Thorlacius Noriya Uedo | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，17： | 14 |
| 6 | Biology and treatment of cervical adenocarcinoma显示文摘Uterine cervical adenocarcinoma(ADC) has been increasing in its prevalence world widely despite the decrease of squamous cell carcinoma(SCC). It comprises nearly 20–25% of the all cervical malignancy in developed countries. The worse biological behavior had been reported in patients with intermediateand high risk factors after surgery, and in advanced stage over III, radiotherapy(RT) alone and concurrent chemo-radiotherapy(CCRT) with cisplatin was not always effective. As for chemotherapy(CT), the induction CT has not established, as well. Further molecular targeted therapy(MTT) has been studied. The targets of oncogenic driver mutations were vascular endothelial growth factor(VEGF) in SCC, or tyrosine kinase(TK) of endothelial growth factor receptor 2(EGFR2, Her2/neu)-Ras-MAPK-ERK pathway. Bevacizumab(Bev, anti-VEGF monoclonal antibody) is considered as one of key agent with paclitaxel and carboplatin in SCC, but not for ADC. This article focuses on up-to-date knowledge of biology and possible specific therapeutic directions to explore in the management of cervical ADC. | Satoshi Takeuchi | 2016 | Chinese Journal of Cancer Research2016，28，2： | 13 |

| 13 | Management of gastric and duodenal neuroendocrine tumors显示文摘Gastrointestinal neuroendocrine tumors(GI-NETs) are rare neoplasms, like all NETs. However, the incidence of GI-NETS has been increasing in recent years. Gastric NETs(G-NETs) and duodenal NETs(D-NETs) are the common types of upper GI-NETs based on tumor location. G-NETs are classified into three distinct subgroups: type?Ⅰ, Ⅱ, and Ⅲ. Type?Ⅰ?G-NETs, which are the most common subtype(70%-80% of all G-NETs), are associated with chronic atrophic gastritis, including autoimmune gastritis and Helicobacter pylori associated atrophic gastritis. Type Ⅱ G-NETs(5%-6%) are associated with multiple endocrine neoplasia type 1 and Zollinger-Ellison syndrome(MEN1-ZES). Both type?Ⅰ?and Ⅱ G-NETs are related to hypergastrinemia, are small in size, occur in multiple numbers, and are generally benign. In contrast, type Ⅲ G-NETs(10%-15%) are not associated with hypergastrinemia, are large-sized single tumors, and are usually malignant. Therefore, surgical resection and chemotherapy are generally necessary for type Ⅲ G-NETs, while endoscopic resection and followup, which are acceptable for the treatment of most type?Ⅰ?and Ⅱ G-NETs, are only acceptable for small and well differentiated type Ⅲ G-NETs. D-NETs include gastrinomas(50%-60%), somatostatin-producing tumors(15%), nonfunctional serotonin-containing tumors(20%), poorly differentiated neuroendocrine carcinomas(< 3%), and gangliocytic paragangliomas(< 2%). Most D-NETs are located in the first or second part of the duodenum, with 20% occurring in the periampullary region. Therapy for D-NETs is based on tumor size, location, histological grade, stage, and tumor type. While endoscopic resection may be considered for small nonfunctional D-NETs(G1) located in the higher papilla region, surgical resection is necessary for most other D-NETs. However, there is no consensus regarding the ideal treatment of D-NETs. | Yuichi Sato Satoru Hashimoto Ken-ichi Mizuno Manabu Takeuchi Shuji Terai | 2016 | World Journal of Gastroenterology2016，22，30： | 10 |
| 14 | Pink-color sign in esophageal squamous neoplasia, and speculation regarding the underlying mechanism显示文摘AIM:To investigate the reasons for the occurrence of the pink-color sign of iodine-unstained lesions. METHODS:In chromoendoscopy, the pink-color sign of iodine-unstained lesions is recognized as useful for the diagnosis of esophageal squamous cell carcinoma. Patients with superficial esophageal neoplasms treated by endoscopic resection were included in the study. Areas of mucosa with and without the pink-color sign were evaluated histologically. The following histologic features that were possibly associated with the pinkcolor sign were evaluated. The keratinous layer and basal cell layer were classified as present or absent. Cellular atypia was classified as high grade, moderate grade or low grade, based on nuclear irregularity, mitotic figures, loss of polarity, chromatin pattern and nuclear/cytoplasmic ratio. Vascular change was assessed based on dilatation, tortuosity, caliber change and variability in shape. Vessels with these four findings were classified as positive for vascular change. Endoscopic images of the lesions were captured immediately after iodine staining, 2-3 min after iodine staining and after complete fading of iodine staining. Quantitative analysis of color changes after iodine staining was also performed. RESULTS:A total of 61 superficial esophageal neoplasms in 54 patients were included in the study. The lesions were located in the cervical esophagus in one case, the upper thoracic esophagus in 10 cases, the mid-thoracic esophagus in 33 cases, and the lower thoracic esophagus in 17 cases. The median diameter of the lesions was 20 mm (range:2-74 mm). Of the 61 lesions, 28 were classified as pink-color sign positive and 33 as pink-color sign negative. The histologic diagnosis was high-grade intraepithelial neoplasia (HGIN) or cancer invading into the lamina propria in 26 of the 28 pink-color sign positive lesions. There was a significant association between pink-color sign positive epithelium and HGIN or invasive cancer (P = 0.0001). Univariate analyses found that absence of the keratinous layer and cellular atypia were significantly associated with the pink-color sign. After Bonferroni correction, there were no significant associations between the pink-color sign and presence of the basal membrane or vascular change. Multivariate analyses found that only absence of the keratinous layer was independently associated with the pink-color sign (OR = 58.8, 95%CI:5.5-632).Quantitative analysis was performed on 10 superficial esophageal neoplasms with both pink-color sign positive and negative areas in 10 patients. Pink-color sign positive mucosa had a lower mean color value in the late phase (pinkish color) than in the early phase (yellowish color), and had similar mean color values in the late and final phases. These findings suggest that pinkcolor positive mucosa underwent color fading from the color of the iodine (yellow) to the color of the mucosa (pink) within 2-3 min after iodine staining. Pink-color sign negative mucosa had similar mean color values in the late and early phases (yellowish color), and had a lower mean color value in the final phase (pinkish color) than in the late phase. These findings suggest that pink-color sign negative mucosa did not undergo color fading during the 2-3 min after iodine staining, and underwent color fading only after spraying of sodium thiosulfate. CONCLUSION:The pink-color sign was associated with absence of the keratinous layer. This sign may be caused by early fading of iodine staining. | Ryu Ishihara Hiromitsu Kanzaki Hiroyasu Iishi Kengo Nagai Fumi Matsui Takeshi Yamashina Noriko Matsuura Takashi Ito Mototsugu Fujii Sachiko Yamamoto Noboru Hanaoka Yoji Takeuchi Koji Higashino Noriya Uedo Masaharu Tatsuta Yasuhiko Tomita Shingo Ishiguro | 2013 | World Journal of Gastroenterology2013，19，27： | 10 |
| 15 | Role of bacterial and genetic factors in gastric cancer in Costa Rica显示文摘AIM: To evaluate several risk factors for gastric cancer (GC) in Costa Rican regions with contrasting GC incidence rate (GCIR). METHODS: According to GCIR, 191 Helicobacter pylori (H pylori)-positive patients were classified into groups A (high GCIR, n = 101) and B (low GCIR, n = 90). Human DNA obtained from biopsy specimens was used in the determination of polymorphisms of the genes coding for interleukin (IL)-1β and IL-10 by PCR-RFLP, and IL-1RN by PCR. H pylori DNA extractions obtained from clinical isolates of 83 patients were used for PCR-based genotyping of H pylori cagA, vacA and babA2. Human DNA from gastric biopsies of 52 GC patients was utilized for comparative purposes. RESULTS: Cytokine polymorphisms showed no association with GCIR variability. However, gastric atrophy, intestinal metaplasia and strains with different vacA genotypes in the same stomach (mixed strain infection) were more frequently found in group A than in group B, and cagA and vacA s1b were signif icantly associated with high GCIR (P = 0.026 and 0.041, respectively). IL- 1β+3954_T/C (OR 2.1, 1.0-4.3), IL-1RN*2/L (OR 3.5, 1.7-7.3) and IL-10-592_C/A (OR 3.2, 1.5-6.8) were individually associated with GC, and a combination of these cytokine polymorphisms with H pylori vacA s1b and m1 further increased the risk (OR 7.2, 1.4-36.4). CONCLUSION: Although a proinflammatory cytokine genetic profile showed an increased risk for developing GC, the characteristics of H pylori infection, in particular the status of cagA and vacA genotype distribution seemed to play a major role in GCIR variability in Costa Rica. | Sergio A Con Hiroaki Takeuchi Gil R Con-Chin Vicky G Con-Chin Nobufumi Yasuda Reinaldo Con-Wong | 2009 | World Journal of Gastroenterology2009，15，2： | 9 |
| 16 | 采用预喷射减少柴油机的NO_x排放显示文摘在一台涡轮增压直喷式柴油机上研究了预喷射对柴油机燃烧的影响。在改变预喷射油量和定时的情况下,测定了各种喷油条件下的发动机排放。结果表明,预喷射能减少低负荷时的NO_x和总HC排放,并能在一定程度上改善燃油耗。为了解这一现象,对柴油机的燃烧进行了分析,并用内窥镜观察了燃烧过程。发现预喷射之所以能降低燃气平均温度是由于限制了预混合燃烧以及延缓扩散燃烧的缘故。摄取了预喷射燃烧产生的燃气被喷入预喷射燃烧火焰中的主喷射油束卷吸而导致燃烧延缓的照片。 | Minami T Takeuchi K Shimazaki N 朱炳全 | 1998 | 国外内燃机1998，30，1： | 9 |
| 17 | 支气管的动脉和气管的分叉的大动脉的 ostia : MDCT 分析显示文摘 AIM:To explore the anatomical relationships between bronchial artery and tracheal bifurcation using computed tomography angiography (CTA).METHODS:One hundred consecutive patients (84 men,16 women;aged 46-85 years) who underwent CTA using multi-detector row CT (MDCT) were investigated retrospectively.The distance between sites of bronchial artery ostia and tracheal bifurcation,and dividing directions were explored.The directions of division from the descending aorta were described as on a clock face.RESULTS:We identified ostia of 198 bronchial arteries:95 right bronchial arteries,67 left bronchial arteries,36 common trunk arteries.Of these,172 (87%) divided from the descending aorta,25 (13%) from the aortic arch,and 1 (0.5%) from the left subclavian artery.The right,left,and common trunk bronchial arteries divided at-1 to 2 cm from tracheal bifurcation with frequencies of 77% (73/95),82% (54/66),and 70% (25/36),respectively.The dividing direction of right bronchial arteries from the descending aorta was 9 to 10 o’clock with a frequency of 81% (64/79);that of left and common tract bronchial arteries was 11 to 1 o’clock with frequencies of 70% (43/62) and 77% (24/31),respectively.CONCLUSION:CTA using MDCT provides details of the relation between bronchial artery ostia and tracheal bifurcation. | Julaiti Ziyawudong Nobuyuki Kawai Morio Sato Akira Ikoma Hiroki Sanda Taizo Takeuchi Hiroki Minamiguchi Motoki Nakai Takami Tanaka Tetsuo Sonomura | 2012 | World Journal of Radiology2012，4，1： | 9 |
| 18 | Comparison of dissimilarity measures for cluster analysis of X-ray diffraction data from combinatorial libraries显示文摘Machine learning techniques have proven invaluable to manage the ever growing volume of materials research data produced as developments continue in high-throughput materials simulation,fabrication,and characterization.In particular,machine learning techniques have been demonstrated for their utility in rapidly and automatically identifying potential composition-phase maps from structural data characterization of composition spread libraries,enabling rapid materials fabrication-structure-property analysis and functional materials discovery.A key issue in development of an automated phase-diagram determination method is the choice of dissimilarity measure,or kernel function.The desired measure reduces the impact of confounding structural data issues on analysis performance.The issues include peak height changes and peak shifting due to lattice constant change as a function of composition.In this work,we investigate the choice of dissimilarity measure in X-ray diffraction-based structure analysis and the choice of measure’s performance impact on automatic composition-phase map determination.Nine dissimilarity measures are investigated for their impact in analyzing X-ray diffraction patterns for a Fe-Co-Ni ternary alloy composition spread.The cosine,Pearson correlation coefficient,and Jensen-Shannon divergence measures are shown to provide the best performance in the presence of peak height change and peak shifting(due to lattice constant change)when the magnitude of peak shifting is unknown.With prior knowledge of the maximum peak shifting,dynamic time warping in a normalized constrained mode provides the best performance.This work also serves to demonstrate a strategy for rapid analysis of a large number of X-ray diffraction patterns in general beyond data from combinatorial libraries. | Yuma Iwasaki A.Gilad Kusne Ichiro Takeuchi | 2017 | npj Computational Materials2017，，1： | 8 |

| 20 | Role of targeted therapy in metastatic colorectal cancer显示文摘Colorectal cancer(CRC) is a significant cause of cancer-related morbidity and mortality all over the world.Improvements of cytotoxic and biologic agents have prolonged the survival in metastatic CRC(mC RC),with a median overall survival of approximately 2 years and more in the past two decades.The biologic agents that have proven clinical benefits in m CRC mainly target vascular endothelial growth factor(VEGF) and epidermal growth factor receptor(EGFR).In particular,bevacizumab targeting VEGF and cetuximab and panitumumab targeting EGFR have demonstrated sig-nificant survival benefits in combination with cytotoxic chemotherapy in the first-line,second-line,or salvage setting.Aflibercept,ramucirumab,and regorafenib are also used in second-line or salvage therapy.Recent retrospective analyses have shown that KRAS or NRAS mutations were negative predictive markers for anti-EGFR therapy.Based on the evidence from large rand-omized clinical trials,personalized therapy is necessary for patients with m CRC according to their tumor biology and characteristics.The aim of this paper was to summarize the results of the major randomized clinical trials and highlight the benefits of the molecular targeted agents in patients with mC RC. | Yoshihito Ohhara Naoki Fukuda Satoshi Takeuchi Rio Honma Yasushi Shimizu Ichiro Kinoshita Hirotoshi Dosaka-Akita | 2016 | World Journal of Gastrointestinal Oncology2016，8，9： | 8 |
