| 1 | Reinfection rate and endoscopic changes after successful eradication of Helicobacter pylori显示文摘AIM:To determine the long-term outcomes regarding reinfection with Helicobacter pylori(H.pylori)and endoscopic changes after successful H.pylori eradication. METHODS:From June 1994 to January 2007,186 patients(M:F=98:88;mean age 50.0±11.4 years), in whom H.pylori had been successfully eradicated, were enrolled.The mean duration of follow up was 41.2±24.0 mo. RESULTS:H.pylori reinfection occurred in 58 patients (31.2%).The average annual reinfection rate was 9.1% per patient year.No recurrence of peptic ulcer was detected at the follow up endoscopy.There were no significant differences between the H.pylori eradication regimens for the reinfection rate and no significant differences in endoscopic findings between the H.pylorirecurred group and the H.pylori-cured group.CONCLUSION:The reinfection rate in Korea is 9.1% which represents a decreasing trend.There was no relationship between H.pylori infection status and changes in endoscopic findings.There was also no recurrence or aggravation of ulcers. | Kum Hei Ryu Sun Young Yi Youn Ju Na Su Jung Baik Su Jin Yoon Hae-Sun Jung Hyun Joo Song | 2010 | World Journal of Gastroenterology2010，16，2： | 14 |
| 2 | Genome-wide identification and analysis of the DREB genes and their expression profiles under abiotic stresses in Chinese jujube(Ziziphus jujuba Mill.)显示文摘CBF/DREB proteins play a critical role in abiotic stress-mediated gene expression and represent attractive regulons for plant breeding programs.However,no study has been conducted for CBF/DREB protein-related genes in jujube(Ziziphus jujuba Mill.).In this study,twenty-five ZjDREB genes were identified and annotated from the jujube(Z.jujuba‘Dongzao’)genome.Detailed analysis,including gene classification,annotation,phylogenetic evaluation,conserved motif determination and expression profiling were performed on all genes.Phylogenetic analysis showed that ZjDREB proteins were divided into five subgroups(A1–A5),but lacking a subgroup A6 corresponding to AtDREBs.The ZjDREB genes were distributed in nine of twelve chromosomes in the genome.Additionally,the expression patterns of the DREB genes under different abiotic stresses were investigated using q RT-PCR.Nineteen ZjDREB genes were down-regulated under low temperature,in contrast six ZjDREB genes(01,03,05,11,23 and 24)were up-regulated.Under drought,salinity and high temperature conditions,expression of ZjDREB03,09,10,14,15,17 and 20 genes were induced and showed similar expression patterns,suggesting that various stress conditions share common elements in the signaling pathway.The results suggest that the family of DREB genes play an important role in abiotic stresses in jujube,and provide a foundation for further functional studies of this important class of transcriptional regulators. | Heying Zhou Jiping Jia Decang Kong Zhendong Zhang Shuang Song Yingyue Li Xiaoming Pang | 2019 | Journal of Forestry Research2019，30，4： | 8 |

| 4 | Thermal Stress in Free-standing Diamond Films with Cr Interlayer Destroyed显示文摘Thermal stress in large area free-standing diamond films was remarkable during the post-deposition cooling of direct current (DC) arc plasma jet chemical vapor deposition (CVD) process.In this research,the stress release caused by delamination of Cr interlayer was of great importance to ensure the integrity of free-standing diamond film.The effects of Cr interlayer on Mo substrate,namely composite substrate,on thermal stress were investigated.Thermo-mechanical coupling analysis of the thermal stress was applied by finite element analysis (FEA) using ANSYS code.It was found that the interlayer could be destroyed first by the large thermal stress,and then the stress could be released and the probability of diamond film crack initiation would be reduced.The stress concentration at the bent edge of diamond film was also discussed.In addition,diamond films deposited on Mo substrates with and without Cr interlayer were prepared by DC arc plasma jet CVD system and experimental measurements were used to characterize these films.It was found that composite substrate could be an effective method of growing free-standing crack-free diamond films by DC arc plasma jet CVD system when there is no special requirement to the film strength. | Zheng Liu,Liangxian Chen,Chengming Li,Lifu Hei,Jianhua Song,Guangchao Chen,Weizhong Tang and Fanxiu Lv School of Materials Science and Engineering,University of Science and Technology Beijing,Beijing 100083,China | 2010 | Journal of Materials Science & Technology2010，26，11： | 1 |
| 5 | Luminescence,Concentration Quenching and Thermal Stability of White Emitting Phosphor Ba_2Ca(BO_3)_2:Dy^(3+)显示文摘A white emitting phosphor Ba2Ca(BO3)2:Dy3+ was synthesized via a high temperature solid state reaction at 1000℃ for 5 h. The luminescence, mole fraction quenching and thermal stability of Ba2Ca(BO3)2:Dy3+ were investigated. According to the phase composition analyzed by X-ray powder diffraction, there is no crystalline phase except Ba2Ca(BO3)2 in the sample. Ba2Ca(BO3)2:Dy3+ can produce white emission under 348 nm excitation. The emission intensities of Ba2Ca(BO3)2:Dy3+ are affected by Dy3+ concentration. The concentration quenching effect was analyzed, and the concentration quenching mechanism was verified as dipole-dipole interaction. The critical distance(R c) obtained based on the crystal structure data is 2.911 nm. At 150℃, the emission intensity of Ba2Ca(BO3)2:Dy3+ is 68.0% of the initial value at room temperature. The activation energy for the thermal quenching calculated is 0.202 e V. Moreover, the CIE chromaticity coordinates of Ba2Ca(BO3)2:Dy3+ locate in the white region of(0.319, 0.356). | SONG Huiling ZHOU Fen CAO Heying GUO Mingchao ZHAO Jiawei WANG Zhijun LIU Haiyan GAO Shaojie LI Panlai | 2015 | Journal of the Chinese Ceramic Society2015，，2： | 1 |

| 13 | Electrochemically activated nickel-cobalt double hydroxide for aqueous ammonium-zinc hybrid battery显示文摘Aqueous rechargeable ammonium-ion(NH^(4+))batteries(AAIBs)with ammonium ions as charge carriers possess many advantages,yet the relatively low discharge capacities(e.g.,<200 mAh·g^(−1))of the reported NH_(4)^(+)host materials hinder the development of AAIBs.Herein,we study the NH_(4)^(+)storage properties of an electrochemically activated NiCo double hydroxide(A-NiCo-DH)in neutral ammonium acetate electrolyte for the first time.The activation process extracts the interlayer anions(NO3from the host material,providing additional cation accommodation sites for charge storage.The introduced H vacancies in A-−)NiCo-DH could activate the O sites,leading to the enhanced cation adsorption capability for the electrode.Therefore,A-NiCo-DH exhibits a high discharge capacity of 280.6 mAh·g^(−1)at 0.72 A·g^(−1)with good rate capability.Spectroscopy studies suggest A-NiCo-DH experiences a NH4+/H+coinsertion mechanism.A NH4+-Zn hybrid cell is assembled using A-NiCo-DH as the cathode and Zn foil as the anode,respectively.The device delivers an energy density of 306 Wh·kg^(−1)at the power density of 745.8 W·kg^(−1)(based on the active mass of A-NiCo-DH).This work provides a new NH_(4)^(+)storage material and would push forward the development of aqueous NH4+-based batteries. | Qing Pan Peng Hei Yu Song Jianming Meng Chang Liu Xiao-Xia Liu | 2023 | Nano Research2023，16，2： | 0 |
| 14 | Observation and mitigation of image distortion in high-energy electron radiography显示文摘Image distortion caused by the angular misalignment of quadrupole magnets in high-energy electron radiography has been studied systematically.We propose that the distortion originates from the coupling of the electron motions in the transverse directions,based on a theoretical analysis and the transfer-matrix method.The relative angular rotation between the second and third magnetic quadrupoles was identified as the main contributor to image distortion.This was verified by both a beam-dynamics simulation and experiments.Different strategies to mitigate this image distortion are also explored,including magnets online tuning,higher beam energy and larger magnification factor.This study provides criteria for designing experiments and paves the way for achieving higher image precision. | Hao-Qing Li Liang Sheng Chang-Qing Zhang Ying-Chao Du Zheng Zhou Xiu-Feng Weng Jia-Hao Xiao Hong-Qiao Yin Bin Sun Kun Wei Yang Li Bao-Jun Duan Yong-Tang Liu Yan-Hong Zhang Mei Zhang Yan Song Xiao-Dong Zhang Jun Liu Zhu-Ming Fu Qing Xu Xue Du Jian-Peng Gao Xin-Yi Wang Xin-Jian Tan Dong-Wei Hei | 2023 | Nuclear Science and Techniques2023，34，6： | 0 |
