| 1 | Protective Effect of Magnesium Isoglycyrrhizinate on Ethanol-Induced Testicular Injuries in Mice显示文摘Objective:Ethanol treatment induces an increase in oxidative stress. As licorice compounds are potent antioxidants, our aim was to examine whether magnesium isoglycyrrhizinate attenuated lipid peroxidation, the major end-point of oxidative damage resulting from ethanol administration. Methods: Four groups(18 animals in each group) of male Kunming mice were used. The first group served as control and received 0.4 ml normal saline daily for 18 days orally. The second group of mice was given 56% ethanol at 16 ml/kg body weight per day for 18 days orally. The third group was given the same dose of ethanol and administrated magnesium isoglycyrrhizinate (15 mg/kg.d, i.p.) for 18 days. The fourth group was given the same dose of ethanol and administrated with magnesium isoglycyrrhizinate (45 mg/kg.d, i.p.) for 18 days. Twenty four hours after 9 days or 18 days of treatment the mice were sacrificed using 10% chloral hydrate. Sperm counts and motility in the epididymis were assessed. The lipid peroxidation and antioxidants of testicular mitochondria were also determined. The pathological changes of testicle tissue of the mice were observed by light microscopy. Results: Magnesium isoglycyrrhizinate effectively prevented the ethanol-induced seminiferous epithelium disorganization and degeneration of Sertoli cells and germ cells. Sperm counts and motility of the magnesium isoglycyrrhizinate treated groups were higher than those of the alcohol treated group, but were lower than those of the control group. The drug exhibited an ability to counteract ethanol induced oxidative challenge as it effectively reduced testicular malondialdehyde (MDA) and increased the activities of superoxide dismutase and glutathione peroxidase. Conclusion: Magnesium isoglycyrrhizinate is able to inhibit the ethanol-induced lipid peroxidation and has a protective effect against testicular oxidative injury. | Yuanqiao He Fuqing Zeng Qing Liu Wen Ju Houju Fu Hua Hao Lulu Lia Yifeng Xie | 2010 | The Journal of Biomedical Research2010，24，2： | 9 |

| 3 | Inhibitive effects of three compositae plants on Microcystis aeruginosa显示文摘Based on common phenomena of biochemical interaction between plants and microorganisms,the inhibitive effects of three common terrestrial compositae plants,namely Artemisia lavandulaefolia DC.,Conyza canadensis(L.)Cronq.,and Kalimeris indica(L.)Sch.-Bip.on the blue algae Microcystis aeruginosa was studied.Live compositae plants are co-cultivated with algae in two different inoculation doses for 10 days in 5-pools incubators,in order to exclude the influence of bacteria and nutrients.The results show that Artemisia lavandulaefolia DC has the most inhibitive potential among the three plants as evidenced by the most drastic decrease in optical density(OD680)of the algae.The inhibition rate is 93.3%(with initial inoculation dose of 2.0×10^(6) Cells/mL)and 89.3%(with initial inoculation dose of 4.0×10^(6) Cells/mL)respectively on the 10th day of cultivation.The average inhibition rate during the later half of the experiment is 0.76(with initial inoculation dose of 2.0×10^(6) Cells/mL)and 0.71(with initial inoculation dose of 4.0×10^(6) Cells/mL),respectively.Logistic model analysis shows that compositae plants such as A.lavandulaefolia DC.causes the reduction of the habitat’s carrying capacity of algae.ANOVA analysis is used to determine the similarity and differences between every experimental group and an average inhibitive rate model is used to evaluate the inhibition effects.The results show that A.lavandulaefolia DC.,which grow well in the aquatic environment,may have a great potential in controlling algae bloom in eutrophic water. | Weihao ZHANG Fuqing XU Wei HE Xing ZHENG Chen YANG | 2009 | Frontiers of Environmental Science & Engineering2009，3，1： | 3 |
| 4 | Bayesian edge detector for SAR imagery using discontinuity-adaptive Markov random feld modeling显示文摘Synthetic aperture radar(SAR)image is severely affected by multiplicative speckle noise,which greatly complicates the edge detection.In this paper,by incorporating the discontinuityadaptive Markov random feld(DAMRF)and maximum a posteriori(MAP)estimation criterion into edge detection,a Bayesian edge detector for SAR imagery is accordingly developed.In the proposed detector,the DAMRF is used as the a priori distribution of the local mean reflectivity,and a maximum a posteriori estimation of it is thus obtained by maximizing the posteriori energy using gradient–descent method.Four normalized ratios constructed in different directions are computed,based on which two edge strength maps(ESMs)are formed.The fnal edge detection result is achieved by fusing the results of two thresholded ESMs.The experimental results with synthetic and real SAR images show that the proposed detector could effciently detect edges in SAR images,and achieve better performance than two popular detectors in terms of Pratt’s fgure of merit and visual evaluation in most cases. | Yuan Zhan He You Cai Fuqing | 2013 | Chinese Journal of Aeronautics2013，26，6： | 2 |

| 6 | Fast Algorithm for Maneuvering Target Detection in SAR Imagery Based on Gridding and Fusion of Texture Features显示文摘Designing detection algorithms with high efficiency for Synthetic Aperture Radar(SAR) imagery is essential for the operator SAR Automatic Target Recognition(ATR) system.This work abandons the detection strategy of visiting every pixel in SAR imagery as done in many traditional detection algorithms,and introduces the gridding and fusion idea of different texture fea-tures to realize fast target detection.It first grids the original SAR imagery,yielding a set of grids to be classified into clutter grids and target grids,and then calculates the texture features in each grid.By fusing the calculation results,the target grids containing potential maneuvering targets are determined.The dual threshold segmentation technique is imposed on target grids to obtain the regions of interest.The fused texture features,including local statistics features and Gray-Level Co-occurrence Matrix(GLCM),are investigated.The efficiency and superiority of our proposed algorithm were tested and verified by comparing with existing fast de-tection algorithms using real SAR data.The results obtained from the experiments indicate the promising practical application val-ue of our study. | YUAN Zhan HE You CAI Fuqing | 2011 | Geo-Spatial Information Science2011，14，3： | 1 |

| 8 | The L-shell ionization of Ho and Os induced by electron impact显示文摘The electron-induced L-shell X-ray par- tial production cross sections, total production cross sections and mean ionization cross sections for Ho and Os have been measured as functions of electron energies from near threshold up to 36 keV by using a thin target with thick substrate technique. The influ- ence of the electrons reflected from the substrate was corrected by using the electron transport biparti- tion model. Also, the corrected measured results were compared with theoretical predictions proposed by Gryzinski and McGuire. | WU Zhangwen, GOU Chengjun, YANG Dailun, PENG Xiufeng, HE Fuqing & LUO Zhengming Key Laboratory for Radiation Physics and Technology of the Education Ministry of China Institute of Nuclear Science and Technology, Sichuan University, Chengdu 610064, China | 2006 | Chinese Science Bulletin2006，51，16： | 0 |
