| 1 | Multicenter study of endoscopic preoperative biliary drainage for malignant distal biliary obstruction显示文摘AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction.METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent(PS) or nasobiliary catheter(NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedurerelated adverse events, stent/catheter dysfunction(occlusion or migration of PS/NBC, developmentof cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution(bilirubin level < 3.0 mg/d L) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis.RESULTS: In total, 419 patients were included in the study(PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients(46%), bile duct cancer in 172(41%), gallbladder cancer in three(1%), and ampullary cancer in 50(12%). The median serum total bilirubin was 7.8 mg/d L and 324 patients(77%) had ≥ 3.0 mg/d L. During the median time to surgery of 29 d [interquartile range(IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio(SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method(PS or NBC).CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored. | Naoki Sasahira Tsuyoshi Hamada Osamu Togawa Ryuichi Yamamoto Tomohisa Iwai Kiichi Tamada Yoshiaki Kawaguchi Kenji Shimura Takero Koike Yu Yoshida Kazuya Sugimori Shomei Ryozawa Toshiharu Kakimoto Ko Nishikawa Katsuya Kitamura Tsunao Imamura Masafumi Mizuide Nobuo Toda Iruru Maetani Yuji Sakai Takao Itoi Masatsugu Nagahama Yousuke Nakai Hiroyuki Isayama | 2016 | World Journal of Gastroenterology2016，22，14： | 18 |

| 4 | Improvement of prognosis for unresectable biliary tract cancer显示文摘AIM:To evaluate the chemotherapeutic outcomes and confirm the recent improvement of prognosis for unresectable biliary tract cancer.METHODS:A total of 186 consecutive patients with unresectable biliary tract cancer,who had been treated with chemotherapy between 2000 and 2009 at five institutions in Japan,were retrospectively analyzed.These patients were divided into three groups based on the year beginning chemotherapy:Group A(2000-2003),Group B(2004-2006),and Group C(2007-2009).The data were fixed at the end of December 2011.Overall survival and time-to-progression were analyzed and compared chronologically.RESULTS:No patient characteristics were significantly different among the three groups.The gallbladder was involved in about half of the patients in each group,and metastatic biliary tract cancer was present in three quarters of the enrollees.In Group A,5-fluorouracilbased chemotherapies were primarily selected as firstline chemotherapy,and only 24% were treated with second-line chemotherapy.In Group B,gemcitabine or S-1 monotherapy was mainly introduced as firstline chemotherapy,and 51% of the patients who were refractory to first-line chemotherapy were treated with second-line chemotherapy mainly with monotherapy.In Group C,the combination therapy with gemcitabine and S-1 was mainly chosen as first-line chemotherapy,and 53% of the patients refractory to first-line chemotherapy were treated with second-line chemotherapy mainly with combination therapy.The median timeto-progressions were 4.4 mo,3.5 mo and 5.9 mo in Groups A,B and C,respectively(4.4 mo vs 3.5 mo vs 5.9 mo,P < 0.01).The median overall survivals were 7.1,7.3,and 11.7 mo in Groups A,B and C(7.1 mo vs 7.3 mo vs 11.7 mo,P = 0.03).Induction rates of all three drugs(gemcitabine,platinum analogs,and fluoropyrimidine) in Groups A,B and C were 4%,2% and 27%(4% vs 2% vs 27%,P < 0.01).CONCLUSION:The prognosis of unresectable biliary tract cancer has improved recently.Using three effective drugs(gemcitabine,platinum analogs,and fluoropyrimidine) may improve the prognosis of this cancer. | Takashi Sasaki Hiroyuki Isayama Yousuke Nakai Naminatsu Takahara Naoki Sasahira Hirofumi Kogure Suguru Mizuno Hiroshi Yagioka Yukiko Ito Natsuyo Yamamoto Kenji Hirano Nobuo Toda Minoru Tada Masao Omata Kazuhiko Koike | 2013 | World Journal of Gastroenterology2013，19，1： | 8 |
| 5 | How Convolutional Neural Networks Diagnose Plant Disease显示文摘Deep learning with convolutional neural networks(CNNs)has achieved great success in the classification of various plant diseases.However,a limited number of studies have elucidated the process of inference,leaving it as an untouchable black box.Revealing the CNN to extract the learned feature as an interpretable form not only ensures its reliability but also enables the validation of the model authenticity and the training dataset by human intervention.In this study,a variety of neuron-wise and layer-wise visualization methods were applied using a CNN,trained with a publicly available plant disease image dataset.We showed that neural networks can capture the colors and textures of lesions specific to respective diseases upon diagnosis,which resembles human decision-making.While several visualizationmethods were used as they are,others had to be optimized to target a specific layer that fully captures the features to generate consequential outputs.Moreover,by interpreting the generated attention maps,we identified several layers that were not contributing to inference and removed such layers inside the network,decreasing the number of parameters by 75%without affecting the classification accuracy.The results provide an impetus for the CNN black box users in the field of plant science to better understand the diagnosis process and lead to further efficient use of deep learning for plant disease diagnosis. | Yosuke Toda Fumio Okura | 2019 | Plant Phenomics2019，1，1： | 6 |
| 6 | Infrasound observations at Syowa Station,East Antarctica:Implications for detecting the surface environmental variations in the polar regions显示文摘Characteristic infrasound waves observed at Antarctic stations demonstrate physical interaction involving environmental changes in the Antarctic continent and the surrounding oceans.A Chaparraltype infrasound sensor was installed at Syowa Station(SYO;39°E,69°S),East Antarctica,as one of the projects of the International Polar Year(IPY2007—2008).Data continuously recorded during the three seasons in 2008—2010 clearly indicate a contamination of the background oceanic signals(microbaroms)with peaks between 4 and 10 s observed during a whole season.The peak amplitudes of the microbaroms have relatively lower values during austral winters,caused by a larger amount of sea-ice extending around the L(u|')tzow-Holm Bay near SYO,with decreasing ocean wave loading effects.Microbaroms measurements are useful tool for characterizing ocean wave climate,complementing other oceanographic and geophysical data.A continuous monitoring by infrasound sensors in the Antarctic firmly contributes to the Comprehensive Nuclear-Test-Ban Treaty(CTBT) in the southern high latitude,together with the Pan-Antarctic Observations System(PAntOS) under the Scientific Committee on Antarctic Research(SCAR).Detailed measurements of the infrasound waves in Antarctica,consequently,could be a new proxy for monitoring regional environmental change as well as the temporal climate variations in the polar regions. | Yoshiaki Ishihara Masaki Kanao Masa-yuki Yamamoto Shigeru Toda Takeshi Matsushima Takahiko Murayama | 2015 | Geoscience Frontiers2015，6，2： | 4 |
| 7 | Clinical analysis of high serum IgE in autoimmune pancreatitis显示文摘AIM: To clarify the clinical significance of high serum IgE in autoimmune pancreatitis (AIP). METHODS: Forty-two AIP patients, whose IgE was measured before steroid treatment, were analyzed. To evaluate the relationship between IgE levels and the disease activity of AIP, we examined (1) Frequency of high IgE (> 170 IU/mL) and concomitant allergic dis-eases requiring treatment; (2) Correlations between IgG, IgG4, and IgE; (3) Relationship between the presence of extrapancreatic lesions and IgE; (4) Re-lationship between clinical relapse and IgE in patients treated with steroids, and (5) Transition of IgE before and after steroid treatment. RESULTS: IgE was elevated in 36/42 (86%) patients.Concomitant allergic disease was observed in seven patients (allergic rhinitis in three, bronchial asthma in three, and urticaria in one). There were no signifi-cant correlations between IgG, IgG4, and IgE (r = -0.168 for IgG, and r = -0.188 for IgG4). There was no significant difference in IgE in the patients with and without extrapancreatic lesions (526 ± 531 IU/mL vs 819 ± 768 IU/mL, P = 0.163), with and without clini-cal relapse (457 ± 346 IU/mL vs 784 ± 786 IU/mL, P = 0.374). There was no significant difference in IgE between before and after steroid treatment (723 ± 744 IU/mL vs 673 ± 660 IU/mL, P = 0.633). CONCLUSION: Although IgE does not necessarily reflect the disease activity, IgE might be useful for the diagnosis of AIP in an inactive stage. | Kenji Hirano Minoru Tada Hiroyuki Isayama Kazumichi Kawakubo Hiroshi Yagioka Takashi Sasaki Hirofumi Kogure Yousuke Nakai Naoki Sasahira Takeshi Tsujino Nobuo Toda Kazuhiko Koike | 2010 | World Journal of Gastroenterology2010，16，41： | 4 |
| 8 | Identification of Naturally Occurring Polyamines as Root-Knot Nematode Attractants显示文摘Root-knot nematodes(RKNs;genus Meloidogyne)are a class of plant parasites that infect the roots of many plant species.It is believed that RKNs target certain signaling molecules derived from plants to locate their hosts;however,currently,no plant compound has been unambiguously identified as a universal RKN attractant.To address this question,we screened a chemical library of synthetic compounds for Meloidogyne incognita attractants.The breakdown product of aminopropylam ino-anthraquinone,1,3-diam inopropane,as well as its related compounds,putrescine and cadaverine,were found to attract M.incognita.After exam ining various polyamines,M.incognita were found to be attracted specifically by natural com pounds that possess three to five methylene groups between two terminal amino groups.Using cryo-TO F-SIM S/SEM,cadaverine was indeed detected in soybean root cortex cells and the surrounding rhizosphere,establishing a chemical gradient.In addition to cadaverine,putrescine and 1,3-diam inopropane were also detected in root exudate by HPLC-MS/MS.Furtherm ore,exogenously applied cadaverine is sufficient to enhance M.incognita infection of Arabidopsis seedlings.These results suggest that M.incognita is likely attracted by polyam ines to locate the appropriate host plants,and the naturally occurring polyamines have potential applications in agriculture in developing protection strategies for crops from RKN infection. | Morihiro Oota Allen Yi-Lun Tsai Dan Aoki Yasuyuki Matsushita Syuuto Toyoda Kazuhiko Fukushima Kentaro Saeki Kei Toda Laetitia Perfus-Barbeoch Bruno Favery Hayato Ishikawa Shinichiro Sawa | 2020 | Molecular Plant2020，13，4： | 4 |
| 9 | Efficacy of tolvaptan in patients with refractory ascites in a clinical setting显示文摘AIM: To elucidate the efficacies of tolvaptan(TLV) as a treatment for refractory ascites compared with conventional treatment. METHODS: We retrospectively enrolled 120 refractory ascites patients between January 1, 2009 and September 31, 2014. Sixty patients were treated with oral TLV at a starting dose of 3.75 mg/d in addition to sodium restriction(> 7 g/d), albumin infusion(10-20 g/wk), and standard diuretic therapy(20-60 mg/d furosemide and 25-50 mg/d spironolactone) and 60 patients with large volume paracentesis in addition to sodium restriction(less than 7 g/d), albumin infusion(10-20 g/wk), and standard diuretic therapy(20-120 mg/d furosemide and 25-150 mg/d spironolactone). Patient demographics and laboratory data, including liver function, were not matched due to the small number of patients. Continuous variables were analyzed by unpaired t-test or paired t-test. Fisher's exact test was applied in cases comparing two nominal variables. We analyzed factors affecting clinical outcomes using receiver operating characteristic curves and multivariate regression analysis. We also used multivariate Cox's proportional hazard regression analysis to elucidate the risk factors that contributed to the increased incidence of ascites.RESULTS: TLV was effective in 38(63.3%) patients. The best cut-off values for urine output and reduced urine osmolality as measures of refractory ascites improvement were > 1800 mL within the first 24 h and > 30%, respectively. Multivariate regression analysis indicated that > 25% reduced urine osmolality [odds ratio(OR) = 20.7; P < 0.01] and positive hepatitis C viral antibodies(OR = 5.93; P = 0.05) were positively correlated with an improvement of refractory ascites, while the total bilirubin level per 1.0 mg/dL(OR = 0.57;P = 0.02) was negatively correlated with improvement. In comparing the TLV group and controls, only the serum sodium level was significantly lower in the TLV group(133 mE q/L vs 136 mE q/L; P = 0.02). However, there were no significant differences in the other parameters between the two groups. The cumulative incidence rate was significantly higher in the control group with a median incidence time of 30 d in the TLV group and 20 d in the control group(P = 0.01). Cox hazard proportional multivariate analysis indicated that the use of TLV(OR = 0.58; P < 0.01), uncontrolled liver neoplasms(OR = 1.92; P < 0.01), total bilirubin level per 1.0 mg/dL(OR = 1.10; P < 0.01), and higher sodium level per 1.0 m Eq/L(OR = 0.94; P < 0.01) were independent factors that contributed to incidence. CONCLUSION: Administration of TLV results in better control of refractory ascites and reduced the incidence of additional invasive procedures or hospitalization compared with conventional ascites treatments. | Takamasa Ohki Koki Sato Tomoharu Yamada Mari Yamagami Daisaku Ito Koki Kawanishi Kentaro Kojima Michiharu Seki Nobuo Toda Kazumi Tagawa | 2015 | World Journal of Hepatology2015，7，12： | 4 |

| 11 | Effects of discharge current and voltage on the high density of metastable helium atoms显示文摘Both hollow-cathode and Penning-type discharges were adopted toexcite helium atoms to a metastable state. Experimental data indicate that Penning discharge is more suitable for generating high fractions of metastables in a low-density helium hean for laser-induced fluorescence technique in measuring electric fields at the edge of a plasma. The metastable density increases with increasing helium gas pressure in the range of 1.33×10^-2-66.7Pa. The highest metastable density of 3.8×10^16m^-3 is observed at a static gas pressure of 66.7Pa. An approximately linear relationship between the density of metastable helium atoms and the plasma discharge current is observed. Magnetic field plays a very important role in producing a high density of metastable atoms in Penning discharge. | FengXian-Ping DAndruczyk BWJames KTakiyama SNamba TOda | 2003 | Chinese Physics B2003，12，5： | 3 |
| 12 | Impact of diabetes on long term follow-up of elderly patients with chronic total occlusion post percutaneous coronary intervention显示文摘Ba ckground The prognosis of elderly patients with chronic total occlusion (CTO) and diabetes mellitus (DM) treated with percutaneous coronary intervention (PCI) is not known. Objective To investigate the effect of diabetes on long-term follow-up of CTO after PCI in elderly patients.Methods A total of 153 elderly patients (age > 65 years old) with CTO lesions which were successfully treated with PCI were enrolled. Fifty one patients with diabetes and 102 without diabetes were compared for long-term outcomes (mean follow up: 36 ±12 months). Major adverse cardiac events (MACE) which include death, myocardial infarction or target lesion revascularization (TLR) were considered as a combined endpoint. Results The combined endpoint occurred in 29.4% of diabetes patients, and 11.3% of the patients without diabetes (P < 0.05). The Cox proportional hazards model identified: drug eluting stent (DES) or bare metal stent (BMS) (HR: 0.13, 95% confidence interval (95%CI): 0.03–0.62, P = 0.004), DM(HR: 6.69, 95% CI: 1.62–15.81, P = 0.01) and final minimal lumen diameter (MLD) (HR: 0.37, 95% CI: 0.13–0.90, P = 0.03 ) as independent predictors of MACE, DM with renal impairment (HR: 6.64, 95% CI: 1.32–33.36, P = 0.02), HBA1C on admission (HR: 1.79, 95% CI: 1.09–2.94, P = 0.02), as independent predictors of MACE at long term follow-up. Conclusions The study demonstrates that DMis a predictive factor for MACE in elderly CTOpatients treatedwith PCI, type of stent, final minimal lumen diameter and DMwith renal impairment, and HBA1C level on admission are predictors of MACE. | Wei Liu Kenji Wagatsuma Hideo Nii Mikihito Toda Hideo Amano Yasuto Uchida | 2013 | Journal of Geriatric Cardiology2013，10，1： | 3 |
| 13 | Coulomb Stress Evolution History as Implication on the Pattern of Strong Earthquakes along the Xianshuihe-Xiaojiang Fault System, China显示文摘Coulomb stress accumulation and releasing history and its relationship with the occurrence of strong historical earthquakes could deepen our understanding of the occurrence pattern of strong earthquakes and hence its seismic potential in future. The sinistral strike-slip Xianshuihe-Xiaojiang fault zone(XXFS) is one of the most dangerous fault zones in China, extending 1 500-kmlong from the central Tibetan Plateau to the Red River fault zone. There are 35 M≥6.5 historical earthquakes occurred since 1327, hence it is an ideal site for studying the Coulomb stress evolution history and its relationship with the occurrences of strong earthquakes. In this study, we evaluated the Coulomb stress change history along the XXFS by synthesizing fault geometry, GPS data and historical earthquakes. Coulomb stress change history also revealed different patterns of historical earthquakes on different segments of the XXFS, such as characteristic recurrence intervals along the Salaha-Moxi fault and super-cycles along the Xianshuihe fault. Based on the occurrence pattern of past historical earthquakes and current Coulomb stress field obtained in this study, we suggest positive ΔCFS and hence high seismic potential along the Salaha-Moxi fault and the Anninghe fault. | Bing Yan Shinji Toda Aiming Lin | 2018 | Journal of Earth Science2018，29，2： | 3 |
