| 4 | Clinicopathological features of early gastric cancers arising in Helicobacter pylori uninfected patients显示文摘BACKGROUND Persistent Helicobacter pylori(H.pylori)infection causes chronic inflammation,atrophy of the gastric mucosa,and a high risk of developing gastric cancer.In recent years,awareness of eradication therapy has increased in Japan.As H.pylori infections decrease,the proportion of gastric cancers arising from H.pylori uninfected gastric mucosa will increase.The emergence of gastric cancer arising in H.pylori uninfected patients though rarely reported,is a concern to be addressed and needs elucidation of its clinicopathological features.AIM To evaluate the clinicopathological features of early gastric cancer in H.pyloriuninfected patients.METHODS A total of 2462 patients with 3375 instances of early gastric cancers that were treated by endoscopic submucosal dissection were enrolled in our study between May 2000 and September 2019.Of these,30 lesions in 30 patients were diagnosed as H.pylori-uninfected gastric cancer(Hp UIGC).We defined a patient as H.pylori-uninfected using the following three criteria:(1)The patient did not receive treatment for H.pylori,which was determined by investigating medical recordsand conducting patient interviews;(2)Lack of endoscopic atrophy;and(3)The patient was negative for H.pylori after being tested at least twice using various diagnostic methods,including serum anti-H.pylori-Ig G antibody,urease breath test,rapid urease test,and microscopic examination.RESULTS The frequency of Hp UIGC was 1.2%(30/2462)for the patients in our study.The study included 19 males and 11 females with a mean age of 59 years.The location of the stomach lesions was divided into three sections;upper third(U),middle third(M),lower third(L).Of the 30 lesions,15 were U,1 was M,and 14 were L.Morphologically,17 lesions were protruded and flat elevated type(0-I,0-IIa,0-IIa+IIc),and 13 lesions were flat and depressed type(0-IIb,0-IIc).The median tumor diameter was 8 mm(range 2-98 mm).Histological analysis revealed that22 lesions(73.3%)were differentiated type.The Hp UIGC lesions were classified into fundic gland type adenocarcinoma(7 cases),foveolar type welldifferentiated adenocarcinoma(8 cases),intestinal phenotype adenocarcinoma(7 cases),and pure signet-ring cell carcinoma(8 cases).Among 30 Hp UIGCs,24 lesions(80%)were limited to the mucosa;wherein,the remaining 6 lesions showed submucosal invasion.One of the submucosal invasive lesions showed more than 500μm invasion.The mucin phenotype analysis identified 7 Hp UIGC with intestinal phenotype and 23 with gastric phenotype.CONCLUSION We elucidated the clinicopathological characteristics of Hp UIGC,revealing recognition not only undifferentiated-type but also differentiated-type.In addition,intestinal phenotype tumors were also observed and could be an important tip. | Chiko Sato Kingo Hirasawa Yoko Tateishi Yuichiro Ozeki Atsushi Sawada Ryosuke Ikeda Takehide Fukuchi Masafumi Nishio Ryosuke Kobayashi Makomo Makazu Hiroaki Kaneko Yoshiaki Inayama Shin Maeda | 2020 | World Journal of Gastroenterology2020，26，20： | 7 |
| 5 | Multi-criteria technique for mapping of debris-covered and clean-ice glaciers in the Shaksgam valley using Landsat TM and ASTER GDEM显示文摘Glaciers in the Shaksgam valley provide important fresh water resources to neighbourhood livelihood. Repeated creation of the glacier inventories is important to assess glacier–climate interactions and to predict future runoff from glacierized catchments. For this study, we applied a multi-criteria technique to map the glaciers of the Shaksgam valley of China, using Landsat Thematic Mapper(Landsat TM)(2009) and Advanced Spaceborne Thermal Emission and Reflection Radiometer Global Digital Elevation Model version two(ASTER GDEM V2) data. The geomorphometric parameters slope, plan, and profile curvature were generated from ASTER GDEM. Then they were organized in similar surface groups using cluster analysis. For accurate mapping of supraglacial debris area, clustering results were combined with a thermal mask generated from the Landsat TM thermal band. The debris-free glaciers were identified using the band ratio(TM band 4/TM band 5) technique. Final vector maps of the glaciers were created using overlay tools in a geographic information system(GIS).Accuracy of the generated glacier outlines was assessed through comparison with glacier outlines based on the Second Chinese Glacier Inventory(SCGI) data and glacier outlines created from high-resolution Google Earth? images of 2009. Glacier areas derived using the proposed approach were 3% less than in the reference datasets. Furthermore, final glacier maps show satisfactory mapping results, but identification of the debris-cover glacier terminus(covered by thick debris layer) is still problematic. Therefore, manual editing was necessary to improve the final glacier maps. | Alifu HAIRETI Ryutaro TATEISHI Bayan ALSAAIDEH Saeid GHARECHELOU | 2016 | Journal of Mountain Science2016，13，4： | 5 |
| 6 | Histopathological validation of magnifying endoscopy for diagnosis of mixed-histological-type early gastric cancer显示文摘BACKGROUND The undifferentiated-type(UDT)component profoundly affects the clinical course of early gastric cancers(EGCs).However,an accurate preoperative diagnosis of the histological types is unsatisfactory.To date,few studies have investigated whether the UDT component within mixed-histological-type(MT)EGCs can be recognized preoperatively.AIM To clarify the histopathological characteristics of the endoscopically-resected MT EGCs for investigating whether the UDT component could be recognized preoperatively.METHODS This was a single-center retrospective study.First,we attempted to clarify the histopathological characteristics of the endoscopically-resected MT EGCs with emphasis on the UDT component.Histopathological examination investigated each lesion’s UDT component:(1)Whole mucosal layer occupation of the UDT component;(2)UDT component exposure to the surface of the mucosa;and(3)existence of a clear border between the differentiated-type and UDT components.Then,preoperative endoscopic images with magnifying endoscopy with narrowband imaging(ME-NBI)were examined to identify whether the endoscopic UDT component finding was recognizable within the area where it was present in the histopathological examination.The preoperative biopsy results and comparative relationships between endoscopic and histopathological findings were also examined.RESULTS In the histopathological examination,the whole mucosal layer occupation of the UDT component and exposure of the UDT component to the mucosal surface were observed in 67.3%(33/49)and 79.6%(39/49)of samples,respectively.A clear distinction of the border between the differentiated-type and UDT components could not be drawn in 65.3%(32/49)of MT lesions.In the endoscopic examination,the preoperative endoscopic images showed that only 24.5%(12/49)of MT EGCs revealed the UDT component within the area where it was present histopathologically.Histopathological UDT predominance was the single significant factor associated with the presence of the endoscopic UDT component finding(61.5%vs 11.1%,P=0.0009).Only 26.5%(13/49)of the lesions were diagnosed from the pretreatment biopsy as having a UDT component.Combined results of the pretreatment biopsy and ME-NBI showed the preoperative presence of the UDT component in 40.8%(20/49)of MT EGCs.CONCLUSION Recognition of a UDT component within MT EGCs is difficult even when pretreatment biopsy and ME-NBI are combined.Endoscopic resection plays a significant role in both treatment and diagnosis. | Yuichiro Ozeki Kingo Hirasawa Ryosuke Kobayashi Chiko Sato Yoko Tateishi Atsushi Sawada Ryosuke Ikeda Masafumi Nishio Takehide Fukuchi Makomo Makazu Masataka Taguri Shin Maeda | 2020 | World Journal of Gastroenterology2020，26，36： | 5 |
| 7 | Assessment of disease progression in patients with transfusion-associated chronic hepatitis C using transient elastography显示文摘AIM:To evaluate the relationship between liver stiffness and duration of infection in blood transfusion-associated hepatitis C virus (HCV) patients with or without hepatocellular carcinoma (HCC).METHODS:Between December 2006 and June 2008,a total of 524 transfusion-associated HCV-RNA positive patients with or without HCC were enrolled.Liver stiffness was obtained noninvasively by using Fibroscan (Echosens,Paris,France).The date of blood transfusion was obtained by interview.Duration of infection was derived from the interval between the date of bloodtransfusion and the date of liver stiffness measurement (LSM).Patients were stratified into four groups based on the duration of infection (17-29 years;30-39 years;40-49 years;and 50-70 years).The difference in liver stiffness between patients with and without HCC was assessed in each group.Multiple linear regression analysis was used to determine the factors associated with liver stiffness.RESULTS:A total of 524 patients underwent LSM.Eight patients were excluded because of unsuccessful measurements.Thus 516 patients were included in the current analysis (225 with HCC and 291 without).The patients were 244 men and 272 women,with a mean age of 67.8 ± 9.5 years.The median liver stiffness was 14.3 kPa (25.8 in HCC group and 7.6 in nonHCC group).The patients who developed HCC in short duration of infection were male dominant,having lower platelet count,with a history of heavier alcohol consumption,showing higher liver stiffness,and receiving blood transfusion at an old age.Liver stiffness was positively correlated with duration of infection in patients without HCC (r=0.132,P=0.024) but not in patients with HCC (r=-0.103,P=0.123).Liver stiffness was significantly higher in patients with HCC than in those without in each duration group (P < 0.0001).The factors significantly associated with high liver stiffness in multiple regression were age at blood transfusion (P < 0.0001),duration of infection (P=0.0015),and heavy alcohol consumption (P=0.043) CONCLUSION:Although liver stiffness gradually increases over time,HCC develops in patients with high stiffness value regardless of the duration of infection. | Ryota Masuzaki Ryosuke Tateishi Haruhiko Yoshida Toru Arano Koji Uchino Kenichiro Enooku Eriko Goto Hayato Nakagawa Yoshinari Asaoka Yuji Kondo Tadashi Goto Hitoshi Ikeda Shuichiro Shiina Masao Omata Kazuhiko Koike | 2012 | World Journal of Gastroenterology2012，18，12： | 4 |

| 15 | Tumor characteristics of ductal carcinoma in situ of breast visualized on [F-18] fluorodeoxyglucose-positron emission tomography/computed tomography: Results from a retrospective study显示文摘AIM To clarify clinicopathological features of ductal carcinoma in situ(DCIS) visualized on [F-18] fluorodeoxyglucosepositron emission tomography/computed tomography(FDG-PET/CT).METHODS This study retrospectively reviewed 52 consecutive tumors in 50 patients with pathologically proven pure DCIS who underwent [F-18] FDG-PET/CT before surgery. [F-18] FDG-PET/CT was performed after biopsy in all patients. The mean interval from biopsy to [F-18] FDGPET/CT was 29.2 d. [F-18] FDG uptake by visual analysis and maximum standardized uptake value(SUVmax) was compared with clinicopathological characteristics.RESULTS[F-18] FDG uptake was visualized in 28 lesions(53.8%) and the mean and standard deviation of SUVmax was 1.63 and 0.90. On univariate analysis, visual analysis and the SUVmax were associated with symptomatic presentation(P = 0.012 and 0.002, respectively), palpability(P = 0.030 and 0.024, respectively), use of core-needle biopsy(CNB)(P = 0.023 and 0.012, respectively), ultrasound-guided biopsy(P = 0.040 and 0.006, respectively), enhancing lesion ≥ 20 mm on magnetic resonance imaging(MRI)(P = 0.001 and 0.010, respectively), tumor size ≥ 20 mm on histopathology(P = 0.002 and 0.008, respectively). However, [F-18] FDG uptake parameters were not significantly associated with age, presence of calcification on mammography, mass formation on MRI, presence of comedo necrosis, hormone status(estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2), and nuclear grade. The factors significantly associated with visual analysis and SUVmax were symptomatic presentation(P = 0.019 and 0.001, respectively), use of CNB(P = 0.001 and 0.031, respectively), and enhancing lesion ≥ 20 mm on MRI(P = 0.001 and 0.049, respectively) on multivariate analysis.CONCLUSION Although DCIS of breast is generally non-avid tumor, symptomatic and large tumors(≥ 20 mm) tend to be visualized on [F-18] FDG-PET/CT. | Tomoyuki Fujioka Kazunori Kubota Akira Toriihara Youichi Machida Kaori Okazawa Tsuyoshi Nakagawa Yukihisa Saida Ukihide Tateishi | 2016 | World Journal of Radiology2016，8，8： | 2 |

| 17 | Hepatic gene expression profiles associated with fibrosis progression and hepatocarcinogenesis in hepatitis C patients显示文摘AIM: To determine fibrosis progression and hepatocellular carcinoma (HCC), using simultaneous gene expression analysis.METHODS: Total RNA samples were extracted from liver biopsies from 19 patients with hepatitis C virus (HCV)infection and 3 patients without HCV infection. Among the 19 HCV-infected patients, 7 and 12 patients had grade F1-2 and F3-4 fibrosis, respectively. Of the 12 patients with F3-4 fibrosis, 8 had HCC. Gene expression in the liver samples was determined using an oligonucleotide microarray. The following comparisons were performed:normal livers vs HCV-infected livers; F1-2 vs F3-4; and F3-4 with HCC vs F3-4 without HCC. Genes that were differentially expressed between these groups were identified based on signal-to-noise ratios.RESULTS: In the HCV-infected livers, genes involved in immune responses were highly expressed. Expression levels of genes for plasma proteins and drug-metabolizing enzymes were decreased and those of genes involved in the cell cycle and oncogenesis were increased in the F3-4 cases as compared to the F1-2 cases. Among the F3-4 cases, genes involved in carbohydrate metabolism tended to be more highly expressed in patients with HCC than in patients without HCC.CONCLUSION: We identified genes that are associated with fibrosis progression and hepatocarcinogenesis. This information may be used to detect increased carcinogenic potential in the livers of patients with HCV infection. | Yujin Hoshida Motoyuki Otsuka Naoya Kato Ryosuke Tateishi Takuma Teratani Shuichiro Shiina Hiroyoshi Taniguchi Masaru Moriyama Takao Kawabe Masao Omata | 2005 | World Journal of Gastroenterology2005，11，13： | 2 |
| 18 | Global mapping of urban built-up areas of year 2014 by combining MODIS multispectral data with VIIRS nighttime light data显示文摘An improved methodology for the extraction and mapping of urban built-up areas at a global scale is presented in this study.The Moderate Resolution Imaging Spectroradiometer(MODIS)-based multispectral data were combined with the Visible Infrared Imager Radiometer Suite(VIIRS)-based nighttime light(NTL)data for robust extraction and mapping of urban built-up areas.The MODIS-based newly proposed Urban Built-up Index(UBI)was combined with NTL data,and the resulting Enhanced UBI(EUBI)was used as a single master image for global extraction of urban built-up areas.Due to higher variation of the EUBI with respect to geographical regions,a region-specific threshold approach was used to extract urban built-up areas.This research provided 500-m-resolution global urban built-up map of year 2014.The resulted map was compared with three existing moderate-resolution global maps and one high-resolution map in the United States.The comparative analysis demonstrated finer details of the urban built-up cover estimated by the resultant map. | Ram C.Sharma Ryutaro Tateishi Keitarou Hara Saeid Gharechelou Kotaro Iizuka | 2016 | International Journal of Digital Earth2016，9，10： | 2 |
| 19 | Cancer-derived VEGF plays no role in malignant ascites formation in the mouse显示文摘AIM: Vascular endothelial growth factor (VEGF) is a potent mediator of peritoneal fluid accumulation following tumor progression. This study investigated the role of VEGF secreted by cancerous cells in the formation of malignant ascites.METHODS: VEGF expression was eliminated byknockdown in the pancreas cancer cell-line PancO2 using vector-based short-hairpin type RNA interference (RNAi).Malignant ascites formation in the mouse was analyzed by intraperitoneal injection of PancO2 cells expressing VEGF or with expression knockdown.RESULTS: The VEGF knockdown PancO2 cell was successfully established. Knockdown of VEGF did not affect cancer cell proliferation in vitro or in vivo. The volume of ascites following peritoneal expansion of the tumor in VEGF knockdown cells and control cells did not differ statistically in this in vivo study. Moreover, the VEGF concentration in the ascites did not differ statistically.CONCLUSION: Malignant ascites formation might be mediated by VEGF production in noncancerous tissues,such as stromal compartments. An anti-VEGF strategy against malignant ascites could be applied to various tumors regardless of whether they secrete VEGF. | Bayasi Guleng Keisuke Tateishi Fumihiko Kanai Amarsanaa Jazag Miki Ohta Yoshinari Asaoka Hideaki Ijichi Yasuo Tanaka Jun Imamura Tsuneo Ikenoue Yasushi Fukushima Keita-Morikane Makoto Miyagishi Kazunari Taira Takao Kawabe Masao Omata | 2005 | World Journal of Gastroenterology2005，11，35： | 2 |
