AIM： To elucidate the influences of Hpylori infection on oral iron treatment for iron deficiency anemia （IDA）.METHODS： A total of 86 patients were divided into two groups： group A, receiving ferrous succinate combined with triple therapy for H pylori eradication, and group B （control）, treated with ferrous succinate only. During treatment of IDA, dynamic changes in hemoglobin （Hb） level, mean corpuscular volume （MCV）, mean corpuscular hemoglobin （MCH）, serum iron （SI）, and serum ferritin （SF） were compared between the groups.RESULTS： Hb was slightly higher in group A at d 14 alter the start of triple therapy for H pylori eradication （P 〉 0.05）. After the therapy, the increase of Hb in group A became significantly faster than that in group B （P 〈 0.05）. At d 56, the mean Hb in group A returned to the normal level, however, in group B, it was lower than that in group A （P 〈 0.05） although it had also increased compared with that before oral iron treatment. The MCV and MCH in group A recovered to the normal level, and were much higher than those in group B （P 〈 0.05） at d 21. In Group B, the MCV and MCH remained at lower than normal levels until d 42 alter the start of therapy. And then, they reached a plateau in both groups and the differences disappeared （P 〉 0.05）. The SF in group A was higher than that in group B （P 〈 0.05） 28 d alter the treatment and its improvement was quicker in group A （P 〈 0.05）, and the difference between the two groups was even more significant （P 〈 0.01） at d 56. The SI in group A was higher than that in group B （P 〈 0.05） at d 14 and this persisted until d 56 when the follow-up of this research was finished.CONCLUSION： Treatment of H pylori can enhance the efficacy of ferrous succinate therapy in IDA patients with Hpylori-positive chronic gastritis.

Research in Astronomy and Astrophysics 2022年第2期22卷 195-203页

作者： lun-hua Shang Jun-Tao Bai Shi-Jun Dang Qi-Jun Zhi School of Physics and Electronic Science Guizhou Normal UniversityGuiyang 550001China School of Electronic and Optical Engineering Nanjing University of Science and TechnologyNanjing 210094China Guizhou Provincial Key Laboratory of Radio Astronomy and Data Processing Guizhou Normal UniversityGuiyang 550001China

We report the "Bi-drifting" subpulses observed in PSR J0815+0939 using the Five-hundred-meter Aperture Spherical radio Telescope(FAST). The observation at band from 1050 to 1450 MHz is evenly divided into two bands, i.e., the bands at center frequencies of 1150 and 1350 MHz. The mean pulse profiles and the "Bi-drifting"subpulses at these two bands are investigated. It is found that the pulse profiles at these two frequencies show four emission components, and the peak separations between four emission components decrease with the increase of frequency. In addition, the ratio of peak intensity of each component to the intensity of component Ⅳ at 1150 MHz is larger than that at 1350 MHz. We carry out an analysis of the longitude-resolved fluctuation spectrum and twodimensional fluctuation spectrum for each emission component, and find that the P3 of components Ⅰ,Ⅱ and Ⅲ is about 10.56, 10.57 and 10.59 s at 1150 and 1350 MHz. However, the reliable measurements of P3 of component IV and P2 for these four components were not obtained due to the low signal-to-noise ratio of observation *** pulse energy distributions at frequencies 1150 and 1350 MHz are presented, and it is found that no nulling phenomenon has been found in this pulsar. With our observation from the FAST, the "Bi-drifting" subpulse phenomenon of PSR J0815+0939 is expanded from 400 to 1350 MHz, which is helpful for the relevant researchers to test and constrain the pulsar emission model, especially the model of "Bi-drifting" subpulse.

Absorption Spectroscopy of （8,1） Band in d^3△-a^3П System of CS Radical

引用

Chinese Journal of Chemical Physics 2012年第5期25卷 513-518,I0003页

作者： Chuan-liang Li lun-hua Deng Yan Zhang Ji-lin Wei Ya ng-qin Chen Department of Physics School of Applied ScienceTaiyuan University of Science and TechnoloEyTaiyuan 030024China State Key Laboratory of Precision Spectroscopy and Department of Physics East China NormalUniversityShanghai 200052China

The CS radical was generated by discharging the mixture gas of CS2 and Helium. The Doppler limited spectra of CS were recorded in the region of 12350-12950 cm^-1 using optical heterodyne concentration modulation absorption spectroscopy. Three hundred and twenty-six lines were recorded and assigned to the d^3△-a^3П （8,1） band, in which eighty-three transitions were first observed. A set of improved molecular constants for the d^3△（v=8） and a^3П（v=1） levels were determined by a non-linear least-squares fitting of all the lines to the effective Hamiltonian.

We perform a global analysis of the new combined data on inclusive structure functions in electron-proton scattering at small value of Bjorken x （x≤0.01） in the framework of the color glass condensate. The new combined HERA data at small-x are studied by an analytic proton structure function. It is shown that the theoretical results of the analytic proton structure function are in agreement with the new combined experimental data. The longitudinal proton structure function is investigated with the analytic expression. It is demonstrated that our approach shows a very good description of the longitudinal structure function experimental data, which is evidence showing the saturation effect is a domination mechanism during the rapidity evolution of the gluon density at high energy.

Journal of Integrative Plant Biology 2007年第9期49卷 1284-1293页

作者： Da-lun Tian Wen-hua Xiang Wen-De Yan Wen-Xing Kang Xiang-Wen Deng Zhu Fan Research Section of Ecology Central-South University of Forestry & Technology Changsha 410004 China

Phytoremediation as a sustainable and inexpensive technology based on the removal of pollutants from the environment by plants is becoming an increasingly important objective in plant research. In this study, biological cycles of five nutrient elements （N, P, K, Ca, and Mg） and eight heavy metal elements （Fe, Cu, Zn, Mn, Cd, Ni, Pb and Co） were examined in young paniculed goldraintree （Koelreuteria paniculata Laxm） and common elaeocarpus （Elaeocarpus decipens） mixed stands in an abandoned mining area. We found that after vegetation restoration in abandoned mining areas, the organic matter and concentrations of nutrient elements were significantly increased and the heavy metal elements were significantly decreased, the annual retention, uptake and return were 75.0, 115.4, and 40.3 kg/hm^2 for nutrient elements, and 1 878.0, 3 231.0 and 1 353.0 g/hm^2 for heavy metal elements, respectively, with the utilization coefficient, cycling coefficient and turnover rate of 0.92, 0.35 and 0.32 for nutrient elements, and 1.24, 0.42 and 1.92 for heavy metal elements, respectively. Our results suggested that the vegetation restoration in abandoned mining areas had significant effects in improving environmental conditions, enhancing soil available nutrients, and ensuring human health.

Chinese Journal of Chemical Physics 2019年第5期32卷 536-542页

作者： Ruo-yu Jiang Jia Ye lun-hua Deng Hai-ling Wang State Key Laboratory of Precision Spectroscopy East China Normal University Shanghai 200062 China

High-resolution absorption spectra of atomic krypton in the range of 11870-12700 cm-1 were recorded by employing concentration modulation absorption spectroscopy technique with a tunable single-mode cw Ti:Sapphire laser. The krypton atoms were excited to the absorbing energy states by discharge-burning in a mixture of helium and krypton. A total of 120 lines of neutral krypton were observed, among them 33 lines had already been classified in previous studies, 45 lines were newly classified with the known energy levels, and 42 lines cannot be classified. These unclassified lines indicate that up to now unknown energy levels of Kr must exist. Further, an analysis of the unclassified lines to get possible new energy levels with a classification program is reported.

KINETICS STUDY ON MELT GRAFTING ACRYLIC ACID ONTO LLDPE USING REACTIVE EXTRUSION

引用

Chinese Journal of Polymer Science 2005年第6期23卷 603-610页

作者： Qiang Shi Lian-chao Zhu Chuan-lun Cai and Jing-hua Yin State Key Laboratory of Polymer Physics and Chemistry,Changchun Institute of Applied Chemistry,Chinese Academy of Sciences,Changchun 130022,China State Key Laboratory of Polymer Physics and Chemistry Changchun Institute of Applied Chemistry Chinese Academy of Sciences Changchun 130022 China

The kinetics of melt grafting acrylic acid （AA） onto linear low density polyethylene （LLDPE） by using reactive extrusion was investigated. The polymeric peroxides （POOP and POOH） generated by electron beam irradiation were used to initiate the graft reaction. The samples taken out from the barrel at five ports along screw axis were analyzed by FTIR. The spectra show that both the graft copolymerization and homopolymerization proceed in two stages： the graft degree （or mass of homopolymer） increases linearly with the reaction time in the initial stage, and then gradually in the second stage. The rate of graft copolymerization Rg is always faster than that of homopolymerization Rh in the present system and the activation energy is 131 kJ · mol^-1 for graft copolymerization and 127 kJ · mol^-1 for homopolymeirzation. These results were interpreted in terms of solubility and diffusion of monomer, as well as the reactivity and the concentration of reactive species. The relationships between reaction rate and monomer concentration and peroxide concentration were found to be： Rg ∞ [M]^1.46[POOP＋POOH]^0.53 and Rh ∞ [M] ^1.08[POOH]^0.51, which indicate that the addition of monomer to polymeric radicals is a slow step for the graft copolymerization.
