| 1 | Retrospective cohort study Lower incidence of complications in endoscopic nasobiliary drainage for hilar cholangiocarcinoma显示文摘AIM:To identify the most effective endoscopic biliary drainage technique for patients with hilar cholangiocarcinoma.METHODS:In total,118 patients with hilar cholangiocarcinoma underwent endoscopic management[endoscopic nasobiliary drainage(ENBD)or endoscopic biliary stenting]as a temporary drainage in our institution between 2009 and 2014.We retrospectively evaluated all complications from initial endoscopic drainage to surgery or palliative treatment.The risk factors for biliary reintervention,post-endoscopic retrograde cholangiopancreatography(post-ERCP)pancreatitis,and percutaneous transhepatic biliary drainage(PTBD)were also analyzed using patient-and procedure-related characteristics.The risk factors for bilateral drainage were examined in a subgroup analysis of patients who underwent initial unilateral drainage.RESULTS:In total,137 complications were observed in92(78%)patients.Biliary reintervention was required in 83(70%)patients.ENBD was significantly associated with a low risk of biliary reintervention[odds ratio(OR)=0.26,95%CI:0.08-0.76,P=0.012].Post-ERCP pancreatitis was observed in 19(16%)patients.An absence of endoscopic sphincterotomy was significantly associated with post-ERCP pancreatitis(OR=3.46,95%CI:1.19-10.87,P=0.023).PTBD was required in 16(14%)patients,and Bismuth type III or IV cholangiocarcinoma was a significant risk factor(OR=7.88,95%CI:1.33-155.0,P=0.010).Of 102 patients with initial unilateral drainage,49(48%)required bilateral drainage.Endoscopic sphincterotomy(OR=3.24,95%CI:1.27-8.78,P=0.004)and Bismuth II,III,or IV cholangiocarcinoma(OR=34.69,95%CI:4.88-736.7,P<0.001)were significant risk factors for bilateral drainage.CONCLUSION:The endoscopic management of hilar cholangiocarcinoma is challenging.ENBD should be selected as a temporary drainage method because of its low risk of complications. | Kazumichi Kawakubo Hiroshi Kawakami Masaki Kuwatani Shin Haba Taiki Kudo Yoko A Taya Shuhei Kawahata Yoshimasa Kubota Kimitoshi Kubo Kazunori Eto Nobuyuki Ehira Hiroaki Yamato Manabu Onodera Naoya Sakamoto | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，9： | 26 |
| 2 | Improving recognition of hepatic perivascular epithelioid cell tumor:Case report and literature review显示文摘A 58-year-old man presented with the chief complaint of abdominal bloating and was incidentally found to have a liver tumor.As diagnostic imaging studies could not rule out malignancy,the patient underwent partial resection of segment 3 of the liver.The lesion pathologically showed eosinophilic proliferation,in addition to immunohistochemical positivity for human melanoma black 45 and Melan-A,thereby leading to the diagnosis of a hepatic perivascular epithelioid cell tumor(PEComa).A PEComa arising from the liver is relatively rare.Moreover,the name ‘PEComa' has not yet been widely recognized,and the same disease entity has been called epithelioid angiomyolipoma(EAML),further diminishing the recognition of PEComa.In addition,PEComa imaging findings mimic those of malignant liver tumors,and clinically,this tumor tends to enlarge.Therefore,a PEComa is difficult to diagnose.We conducted a systematic review of PEComa and EAML cases and discuss the results,including findings useful for differentiating perivascular epithelioid cell tumors from malignant liver tumors. | Toshiya Maebayashi Katsumi Abe Takuya Aizawa Masakuni Sakaguchi Naoya Ishibashi Osamu Abe Tadatoshi Takayama Hisashi Nakayama Shunichi Matsuoka Kazushige Nirei Hitomi Nakamura Masahiro Ogawa Masahiko Sugitani | 2015 | World Journal of Gastroenterology2015，21，17： | 20 |
| 3 | Neoadjuvant treatment for esophageal squamous cell carcinoma显示文摘Squamous cell carcinoma and adenocarcinoma are types of esophageal cancer, one of the most aggressive malignant diseases. Since both histological types present entirely different diseases with different epidemiology, pathogenesis and tumor biology, separate therapeutic strategies should be developed against each type. While surgical resection remains the dominant therapeutic intervention for patients with operable esophageal squamous cell carcinoma(ESCC), alternative strategies are actively sought to reduce the frequency of post-operative local or distant disease recurrence. Such strategies are particularly sought in the preoperative setting. Currently, the optimal management of resectable ESCC differs widely between Western and Asian countries(such as Japan). While Western countries focus on neoadjuvant or definitive chemoradiotherapy, neoadjuvant chemotherapy followed by surgery is the standard treatment in Japan. Importantly, each country and region has established its own therapeutic strategy from the results of local randomized control trials. This review discusses the current knowledge, available data and information regarding neoadjuvant treatment for operable ESCC. | Yoshifumi Baba Masayuki Watanabe Naoya Yoshida Hideo Baba | 2014 | World Journal of Gastrointestinal Oncology2014，6，5： | 17 |
| 4 | Cytokines in adipose-derived mesenchymal stem cells promote the healing of liver disease显示文摘Adipose-derived mesenchymal stem cells(ADSCs) are a treatment cell source for patients with chronic liver injury. ADSCs are characterized by being harvested from the patient's own subcutaneous adipose tissue, a high cell yield(i.e., reduced immune rejection response), accumulation at a disease nidus, suppression of excessive immune response, production of various growth factors and cytokines, angiogenic effects, antiapoptotic effects, and control of immune cells via cellcell interaction. We previously showed that conditioned medium of ADSCs promoted hepatocyte proliferation and improved the liver function in a mouse model of acute liver failure. Furthermore, as found by many other groups, the administration of ADSCs improved liver tissue fibrosis in a mouse model of liver cirrhosis. A comprehensive protein expression analysis by liquid chromatography with tandem mass spectrometry showed that the various cytokines and chemokines produced by ADSCs promote the healing of liver disease. In this review, we examine the ability of expressed protein components of ADSCs to promote healing in cell therapy for liver disease. Previous studies demonstrated that ADSCs are a treatment cell source for patients with chronic liver injury. This review describes the various cytokines and chemokines produced by ADSCs that promote the healing of liver disease. | Saifun Nahar Yoshiki Nakashima Chika Miyagi-Shiohira Takao Kinjo Zensei Toyoda Naoya Kobayashi Issei Saitoh Masami Watanabe Hirofumi Noguchi Jiro Fujita | 2018 | World Journal of Stem Cells2018，10，11： | 11 |
| 5 | Lansoprazole ameliorates intestinal mucosal damage induced by ischemia-reperfusion in rats显示文摘AIM: To investigate the protective effect of lansoprazoleon ischemia and reperfusion (I/R)-induced rat intestinalmucosal injury in vivo.METHODS: Intestinal damage was induced by clampingboth the superior mesenteric artery and the celiac trunkfor 30 rain followed by reperfusion in male Sprague-Dawleyrats. lansoprazole was given to rats intraperitoneally 1 hbefore vascular clamping.RESULTS: Both the intraluminal hemoglobin and proteinlevels, as indices of mucosal damage, significantlyincreased in I/R-groups comparion with those of sham-operation groups. These increases in intraluminal hemoglobinand protein levels were significantly inhibited by the treatmentwith lansoprazole at a dose of 1 mg/kg. Small intestineexposed to I/R resulted in mucosal inflammation that wascharacterized by significant increases in thiobarbituric acid-reactive substances (TBARS), tissue-associatedmyeloperoxidase activity (MPO), and mucosal content of ratcytokine-induced neutrophil chemoattractant-1 (CINC-1).These increases in TBARS, MPO activities and CINC-1 contentin the intestinal mucosa after I/R were all inhibited bypretreatment with lansoprazole at a dose of 1 mg/kg.Furthermore, the CINC-1 mRNA expression was increasedduring intestinal I/R, and this increase in mRNA expressionwas inhibited by treatment with lansoprazole.CONCLUSION: Lansoprazole inhibits lipid peroxidation andreduces development of intestinal mucosal inflammationinduced by I/R in rats, suggesting that lansoprazole mayhave a therapeutic potential for I/R injury. | Hiroshi Ichikawa Norimasa Yoshida Tomohisa Takagi Naoya Tomatsuri Kazuhiro Katada Yutaka Isozaki Kazuhiko Uchiyama Yuji Naito Takeshi Okanoue Toshikazu Yoshikawa | 2004 | World Journal of Gastroenterology2004，10，19： | 10 |
| 6 | Low-grade myofibroblastic sarcoma of the palate显示文摘Low-grade myofibroblastic sarcoma(LGMS) is a rare,malignant tumor with myofibroblastic differentiation.Despite it being classified as a distinct entity by the World Health Organization,a few cases were reported in the oral and maxillofacial region.Here,a LGMS developed on the palate of a 73-year-old man who presented with a 1-cm tumor on the posterior border of the palate.Based on the histological and immunohistochemical features,a diagnosis of LGMS was established.The tumor was resected,and no recurrence was observed over 2 years.Although the tongue is the most preferred site for LGMS,it may occur in any region of the oral cavity. | Tomohiro Yamada Tomohide Yoshimura Naoya Kitamura Eri Sasabe Seiji Ohno Tetsuya Yamamoto | 2012 | International Journal of Oral Science2012，4，3： | 9 |
| 7 | Usefulness of vonoprazan,a potassium ion-competitive acid blocker,for primary eradication of Helicobacter pylori显示文摘AIM To investigate usefulness of triple therapy with vonoprazan,a potassium ion-competitive acid blocker and antibiotics,for Helicobacter pylori(H.pylori) eradication.METHODS The H.pylori eradication rate was examined in 2507 patients(2055 undergoing primary eradication and 452 undergoing secondary eradication,excluding patients with subtotal gastrectomy) at the Japanese Red Cross Kyoto Daiichi Hospital from March 2013 to September 2015.For patients treated from March 2013 to February 2015,a proton pump inhibitor(PPI) was used to reduce acid secretion,while vonoprazan was used after March 2015.The success rates of the 2 regimens(PPI + amoxicillin + clarithromycin/metronidazole,or vonoprazan + amoxicillin + clarithromycin/metronidazole) were compared.RESULTS The success rate of primary H.pylori eradication was significantly higher in the vonoprazan group.When stratified by the underlying disease,a significant increase of the H.pylori eradication rate was observed in patients with chronic gastritis.A significantly lower H.pylori eradication rate was observed in younger patients compared to older patients in the PPI group,but there was no difference according to age in the vonoprazan group.On the otherhand,the success rate of secondary eradication was similar at approximately 90% in both groups.CONCLUSION Vonoprazan is very useful for primary eradication of H.pylori,and may become a first-line acid secretion inhibitor instead of PPIs. | Shinya Yamada Takumi Kawakami Yoshikazu Nakatsugawa Takahiro Suzuki Hideki Fujii Naoya Tomatsuri Hideki Nakamura Hideki Sato Yusuke Okuyama Hiroyuki Kimura Norimasa Yoshida | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，4： | 8 |
| 8 | Short-and long-term results of endoscopic ultrasoundguided transmural drainage for pancreatic pseudocysts and walled-off necrosis显示文摘AIM To evaluate the short-and long-term results of endoscopic ultrasound-guided transmural drainage(EUS-GTD) for pancreatic fluid collection(PFC) and identify the predictive factors of treatment outcome for walled-off necrosis(WON) managed by EUS-GTD alone.METHODS We investigated 103 consecutive patients with PFC who underwent EUS-GTD between September 1999 and August 2015. Patients were divided into four groups as follows: WON(n = 40), pancreatic pseudocyst(PPC; n = 11), chronic pseudocyst(n = 33), and others(n = 19). We evaluated the short-and long-term outcomes of the treatment. In cases of WON, multiple logistic regression analyses were performed to identify the predictor variables associated with the treatment success. In addition, PFC recurrence was examined in patients followed up for more than 6 mo and internal stent removal after successful EUS-GTD was confirmed.RESULTS In this study, the total technical success rate was 96.1%. The treatment success rate of WON, PPC, chronic pseudocyst, and others was 57.5%, 90.9%, 91.0%, and 89.5%, respectively. Contrast-enhanced computed tomography using the multivariate logistic regression analysis revealed that the treatment success rate of WON was significantly lower in patients with more than 50% pancreatic parenchymal necrosis(OR = 17.0; 95%CI: 1.9-150.7; P = 0.011) and in patients with more than 150 mm of PFC(OR = 27.9; 95%CI: 3.4-227.7; P = 0.002).The recurrence of PFC in the long term was 13.3%(median observation time, 38.8 mo). Mean amylase level in the cavity was significantly higher in the recurrence group than in the no recurrence group(P = 0.02).CONCLUSION The reduction of WON by EUS-GTD alone was associated with the proportion of necrotic tissue and extent of the cavity. The amylase level in the cavity may be a predictive factor for recurrence of PFC. | Yuto Watanabe Rintaro Mikata Shin Yasui Hiroshi Ohyama Harutoshi Sugiyama Yuji Sakai Toshio Tsuyuguchi Naoya Kato | 2017 | World Journal of Gastroenterology2017，23，39： | 7 |
| 9 | Utility 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 | 2015 | World Journal of Stem Cells2015，7，5： | 7 |
| 10 | Evaluating 3D position and velocity of subject in parabolic flight experiment by use of the binocular stereo vision measurement显示文摘A practical method for evaluating the three-dimensional(3D) position and velocity of a moving object used in the parabolic flight experiment is developed by using the binocular stereo vision measurement theory. The camera calibration mathematic model without considering the lens distortion is introduced.The direct linear transformation(DLT) algorithm is improved to accomplish the camera calibration.The camera calibration result and optimization algorithm are used to calculate the object's world coordinate from image coordinate.The 3D position and the velocity of the moving object are obtained.The standard uncertainty in estimating the velocity is 0.0024 m/s,which corresponds to 1%level of the velocity of the object in the experiment.The results show that this method is very useful for the parabolic flight experiments. | 金涛 贾宏志 侯文玫 Ryo Yamamoto Norihiro Nagai Yusaku Fujii Koichi Maru Naoya Ohta Kazuhito Shimada | 2010 | Chinese Optics Letters2010，8，6： | 6 |
| 11 | The increase in surface CXCR4 expression on lung extravascular neutrophils and its effects on neutrophils during endotoxin-induced lung injury显示文摘Inflammatory stimuli,such as a microbes or lipopolysaccharides,induce a rapid release of neutrophils from the bone marrow and promote neutrophil migration into inflamed sites to promote host defense.However,an excess accumulation and retention of neutrophils in inflamed tissue can cause severe tissue injuries in the later stages of inflammation.Recent studies have reported that both CXCL12 levels in injured lungs and its receptor,CXCR4,on accumulated neutrophils in injured lungs,increased;furthermore,these studies showed that the CXCL12/CXCR4 signaling pathway participated in neutrophil accumulation in the later stages of lipopolysaccharide(LPS)-induced lung injury.However,the mechanisms underlying this increase in surface CXCR4 expression in neutrophils remain unclear.In this study,we found that surface CXCR4 expression increased in extravascular,but not intravascular,neutrophils in the lungs of LPS-induced lung injury model mice.Furthermore,ex vivo studies revealed that CXCL12 acted not only as a chemoattractant,but also as a suppressor of cell death for the lung neutrophils expressing CXCR4.Sulfatide,one of the native ligands for L-selectin,induced the increase of surface CXCR4 expression on isolated circulating neutrophils,suggesting that the activation of L-selectin may be involved in the increase in surface CXCR4.Our findings show that surface CXCR4 levels on neutrophils increase after extravasation into injured lungs,possibly through the activation of L-selectin.The CXCL12/CXCR4 signaling pathway plays an important role in the modulation of neutrophil activity during acute lung injury,not only by promoting chemotaxis but also by suppressing cell death. | Mitsuhiro Yamada Hiroshi Kubo Seiichi Kobayashi Kota Ishizawa Mei He Takaya Suzuki Naoya Fujino Hiroyuki Kunishima Masamitsu Hatta Katsushi Nishimaki Tetsuji Aoyagi Kouichi Tokuda Miho Kitagawa Hisakazu Yano Hirokazu Tamamura Nobutaka Fujii Mitsuo Kaku | 2011 | Cellular & Molecular Immunology2011，8，4： | 6 |
| 12 | Biochemically curative surgery for gastrinoma in multiple endocrine neoplasia type 1 patients显示文摘AIM: To search for the optimal surgery for gastrinoma and duodenopancreatic neuroendocrine tumors in patients with multiple endocrine neoplasia type 1. METHODS: Sixteen patients with genetically confirmed multiple endocrine neoplasia type 1 (MEN 1) and Zollinger-Ellison syndrome (ZES) underwent resection of both gastrinomas and duodenopancreatic neuroendocrine tumors (NETs) between 1991 and 2009. For localization of gastrinoma, selective arterial secretagogue injection test (SASI test) with secretin or calcium solution was performed as well as somatostatin receptor scintigraphy (SRS) and other imaging methods such as computed tomography (CT) or magnetic resonance imaging (MRI). The modus of surgery for gastrinoma has been changed over time, searching for the optimal surgery: pancreaticoduodenectomy (PD) was first performed guided by localization with the SAST test, then local resection of duodenal gastrinomas with dissection of regional lymph nodes (LR), and recently pancreas-preserving total duodenectomy (PPTD) has been performed for multiple duodenal gastrinomas. RESULTS: Among various types of preoperative localizing methods for gastrinoma, the SASI test was the most useful method. Imaging methods such as SRS or CT made it essentially impossible to differentiate functioning gastrinoma among various kinds of NETs. However, recent imaging methods including SRS or CT were useful for detecting both distant metastases and ectopic NETs; therefore they are indispensable for staging of NETs. Biochemical cure of gastrinoma was achieved in 14 of 16 patients (87.5%); that is, 100% in 3 patients who underwent PD, 100% in 6 patients who underwent LR (although in 2 patients (33.3%) second LR was performed for recurrence of duodenal gastrinoma), and 71.4% in 7 patients who underwent PPTD. Pancreatic NETs more than 1 cm in diameter were resected either by distal pancreatectomy or enucleations, and no hepatic metastases have developed postoperatively. Pathological study of the resected specimens revealed co-existence of pancreatic gastrinoma with duodenal gastrinoma in 2 of 16 patients (13%), and G cell hyperplasia and/or microgastrinoma in the duodenal Brunner's gland was revealed in all of 7 duodenal specimens after PPTD. CONCLUSION: Aggressive resection surgery based on accurate localization with the SASI test was useful for biochemical cure of gastrinoma in patients with MEN 1. | Masayuki Imamura Izumi Komoto Shuichi Ota Takuya Hiratsuka Shinji Kosugi Ryuichiro Doi Masaaki Awane Naoya Inoue | 2011 | World Journal of Gastroenterology2011，17，10： | 5 |
| 13 | Improvement of photocatalytic activity of high specific surface area graphitic carbon nitride by loading a co-catalyst显示文摘Graphitic carbon nitride(g-C3N4)was synthesized by heating melamine and was then treated with sodium hydroxide solution under a hydrothermal condition to obtain g-C3N4 with a large specific surface area(HSSA).HSSA shows higher photocatalytic activity for decomposition of acetaldehyde than that of original g-C3N4.HSSA was modified with RuO2 as a co-catalyst by the impregnation method.HSSA loaded with 0.05 wt%RuO2 shows the highest photocatalytic activity for acetaldehyde decomposition under visible light(k=455 nm). | Ye Chen Naoya Murakami Hai-Yan Chen Jia Sun Qi-Tao Zhang Zhi-Feng Wang Teruhisa Ohno Ming Zhang | 2019 | Rare Metals2019，38，5： | 5 |
| 14 | Protocol liver biopsy is the only examination that can detect mid-term graft fibrosis after pediatric liver transplantation显示文摘AIM:To assessed the clinical significance of protocol liver biopsy(PLB)in pediatric liver transplantation(LT).METHODS:Between July 2008 and August 2012,89and 55 PLBs were performed in pediatric patients at two and five years after LT,respectively.We assessed the histopathological findings using the Metavir scoring system,including activity(A)and fibrosis(F),and we identified factors associated with scores of≥A1 and≥F1.Our results clarified the timing and effectiveness of PLB.RESULTS:The incidences of scores of≥A1 and≥F1 were 24.7%and 24.7%,respectively,at two years after LT and 42.3%and 34.5%,respectively,at five years.Independent risk factors in a multivariate analysis of a score of≥A1 at two years included≥2 h ofcold ischemic time,no acute cellular rejection and an alanine amino transaminase(ALT)level of≥20 IU/L(P=0.028,P=0.033 and P=0.012,respectively);however,no risk factors were identified for a score of≥F1.Furthermore,no independent risk factors associated with scores of≥A1 and≥F1 at five years were identified using multivariate analysis.A ROC curve analysis of ALT at two years for a score of≥A1 demonstrated the recommended cutoff value for diagnosing≥A1 histology to be 20 IU/L.The incidence of scores of≥A2 or≥F2 at two years after LT was 3.4%(three cases),and all patients had an absolute score of≥A2.In contrast to that observed for PLBs at five years after LT,the incidence of scores of≥A2 or≥F2 was 20.0%(11 cases),and all patients had an absolute score of≥F2.In all cases,the dose of immunosuppressants was increased after the PLB,and all ten patients who underwent a follow-up liver biopsy improved to scores of≤A1 or F1.CONCLUSION:PLB at two years after LT is an unnecessary examination,because the serum ALT level reflects portal inflammation.In addition,immunosuppressive therapy should be modulated to maintain the ALT concentration at a level less than 20 IU/L.PLB at five years is an excellent examination for the detection of early reversible graft fibrosis because no serum markers reflect this finding. | Yukihiro Sanada Koshi Matsumoto Taizen Urahashi Yoshiyuki Ihara Taiichi Wakiya Noriki Okada Naoya Yamada Yuta Hirata Koichi Mizuta | 2014 | World Journal of Gastroenterology2014，20，21： | 5 |
| 15 | Eco-morphological characteristics of fern species for slope conservation显示文摘Degradation of slopes due to shallow landslide and the subsequent erosional processes are a big challenge on the application of soil bioengineering techniques; that is the use of plants as main structural components of a slope protection and conservation system. An optimal application of soil bioengineering techniques should include not only the technical factor of plants as structural components but also the ecology of species and the plant adaptations to disturbances, which is crucial if a longterm successful slope restoration system is intended. Ferns are a dominant understory vegetation species in the forest of Japan, but its characteristics and influences on the recovery of shallow landslide scars have not been fully studied yet. This study aims to find out the ecological characteristics of fern species through the calculation of ecological indicators and the quantification of the morphological features of specimens growing on disturbed and non-disturbed forest slopes in Japan. Gleichenia japonica was found as the vegetation species with biggest ecological indicators on both slopes. The analysis of morphological characteristics of the specimens growing on both sites showed that the development of the specimens is focused in below-ground characteristics. The pull-out force of Gleichenia japonica root system as an indicator of ecological adaptation to a constraint environment and morphological characteristics quality is influenced by height and root length according to the principal component analysis. The eco-morphological characteristics of species can be used as an indicator of an optimal element in soil bioengineering establishment for slope conservation proposes. The long and fibrous root system could be placed on forest roads, steep or small slopes where space limitation is an issue for the establishment of bigger species and if the slope conditions allow it, it can control soil losses due to rainfall and provide stability. | Laura SANCHEZ-CASTILLO Ken’ichirou KOSUGI Naoya MASAOKA Tetsuya KUBOTA | 2019 | Journal of Mountain Science2019，16，3： | 4 |

| 18 | Synthesis of anatase TiO2 with exposed {001} and {101} facets and photocatalytic activity显示文摘Anatase titanium(IV) oxide (TiO2) particles with exposed {()01) and {101) facets were prepared by hydrothermal treatment of amorphous TiO2 with H2O2- NH3 solution. Crystal phase, shape, and size of TiO2 particles are found to be greatly dependent on the ratio of H2O2-NH3 solution. The prepared TiOo particles with specific exposed crystal faces show higher photocatalytic activity for acetaldehyde decomposition than commercial spherical TiO^ particles. This result implies that recombination is prevented by spatial separation of redox sites in the particles because of selective migration of electrons and positive holes to specific exposed crystal faces and/or different reactivity of electrons and positive holes on the specific exposed crystal face. | Jia Sun Ming Zhang Zhi-Feng Wang Hai-Yan Chen Ye Chen Naoya Murakami Teruhisa Ohno | 2019 | Rare Metals2019，38，4： | 3 |
| 19 | Gastroduodenal ulcer bleeding in elderly patients on low dose aspirin therapy显示文摘AIM To determine the clinical characteristics of elderly patients of hemorrhagic gastroduodenal ulcer on low-dose aspirin(LDA)therapy.METHODS A total of 1105 patients with hemorrhagic gastroduodenal ulcer treated in our hospital between January 2000 and March 2016 were grouped by age and drugs used,and these groups were compared in several factors.These groups were compared in terms of length of hospital stay,presence/absence of hemoglobin(Hb)decrease,presence/absence of blood transfusion,Forrest Ⅰ,percentage of Helicobacter pylori infection,presence/absence of underlying disease,and percentage of severe cases.RESULTS The percentage of blood transfusion(62.6%vs 47.7%,P<0.001),Hb decrease(53.8% vs 40.8%,P<0.001),and the length of hospital stay(23.5 d vs 16.7 d,P<0.001)were significantly greater in those on drug therapy.The percentage of blood transfusion(65.3%vs 47.8%,P<0.001),Hb decrease(54.2%vs 42.1%,P<0.001),and length of hospital stay(23.3 d vs 17.5 d,P<0.001)were significantly greater in the elderly.In comparison with the LDA monotherapy group,the percentage of severe cases was significantly higher in the LDA combination therapy group when elderly patients were concerned(16.1%vs34.0%,P=0.030).Meanwhile,among those on LDA monotherapy,there was no significant difference between elderly and non-elderly(16.1%vs 16.0%,P=0.985).CONCLUSION A combination of LDA with antithrombotic drugs or nonsteroidal anti-inflammatory drugs(NSAIDs)contributes to aggravation.And advanced age is not an aggravating factor when LDA monotherapy is used. | Koh Fukushi Keiichi Tominaga Kazunori Nagashima Akira Kanamori Naoya Izawa Mimari Kanazawa Takako Sasai Hideyuki Hiraishi | 2018 | World Journal of Gastroenterology2018，24，34： | 3 |
