| 1 | Topographical Evaluation of the Decentration of Orthokeratology Lenses显示文摘Purpose: To evaluate the amount of lens decentration and various factors affecting decentration after orthokeratology lens wear and to observe the effect of decentration on the visual functions.Methods: Two kinds of orthokeratology lenses were fitted to 270 eyes of 135 patients [initial mean refractive error: (-3.98±1.51)D]. Humphery Instruments ATLAS 990 was used for the computer-assisted analysis of corneal topographical maps. The examination of corneal topography was performed on patients before and after 6 months of wearing orthokeratology lenses. The amount of decentration of orthokeratology lenses was measured by finding the distance between center of optic zone and the pupil center. The factors influencing the amount of decentration were analyzed, including the initial refraction error, astigmatism, keratometry values, corneal eccentricity, and the diameter of lens.Visual symptoms including monocular diplopia, glare around lights were recorded to evaluate the effects of decentration on visual functions.Results: The mean amount of decentration was (0.49±0.34) mm after one night's wear.The mean amount of decentration after 1 month, 3 months and 6 months was (0.57±0.41) mm, (0.55±0.48) mm and (0.59±0.39) mm, respectively. After one month, the amount of decentration was less than 0.50 mm in 51.1% eyes, 0.50~1.0 mm in 35.6% eyes and more than 1.00 mm in 13.3% eyes. The direction of decentration of more than 0.50 mm was mainly in the temporal quadrant (48.5%). Patients with greater initial astigmatism and smaller lenses showed greater decentration (P<0.05). There was no statistically significant difference in decentration between the two groups with different corneal eccentricities and keratometry values (P>0.05). The amount of decentration was greater in patients who complained of monocular diplopia and glare.Conclusions: The amount of decentration of orthokeratology depends on the initial refractive error, astigmatism and the design of orthokeratology lenses. Improvement in fitting technology and lens design can lead to reduced incidence of decentration and visual symptoms. | Xiao Yang Xingwu Zhong Xiangming Gong Junwen Zeng | 2005 | Eye Science2005，21，3： | 10 |
| 2 | Combined Application of 5% Natamycin and 0.2% Fluconazole for the Treatment of Fungal Keratitis显示文摘Purpose: To observe the clinical efficacy of combined use of 5% natamycin and 0.2% fluconazole for the treatment of fungal keratitis. Methods:A total of 65 cases diagnosed with fungal keratitis by direct smear and/or fungus culture from January 2010 to January 2013 were enrolled in this study.The duration from the onset of symptoms to admission to our ophthalmic center ranged from 9 to 90 d (mean 29.5 ±19.1 d) in the severe group, which significantly differed from the 7 to 36 d (mean 16.6±7.1 d) in the non-severe group (P<0.01). All cases were divided into non-severe and severe groups based on the degree of corneal inflammation. All cases were treated with topical use of 5% natamycin and 0.2% fluconazole once per hour. The same clinical and examination protocols were adopted for both groups. Results:In the non-severe group,23 of the 24 patients (95.8%) were healed, and 1 (4.2%) showed treatment effica cy. In the severe group,12 of 41 patients (29.3%) were healed, 11(26.8%) showed clinical efficacy, and 18(43.9%) showed no efficacy. The patients between two groups significantly differed in terms of efficacy (P<0.01). Conclusion:Combined use of 5% natamycin and 0.2% fluconazole is efficacious in treating fungal keratitis, especially mild or moderate infections. | Hua Gong Xiangming Gong | 2013 | Eye Science2013，28，2： | 7 |

| 6 | Machine-learning based ocean atmospheric duct forecasting:a hybrid model-data-driven approach显示文摘The atmospheric duct is a vital radio wave environment.Conventional methods of forecasting the atmospheric duct mainly include statistical analysis based on sounding observation data and mesoscale numerical model-based prediction.The former can provide accurate duct information but is highly dependent on the acquisition of data sets.The latter is more practical but still lacks accuracy.This paper introduces machine learning to establish a novel meteorological parameter correction model for atmospheric duct prediction.In detail,using the weather research and forecasting(WRF)model data and spatiotemporal characteristics as input,sounding data as label and extreme gradient boosting(XGBoost)model for training,the meteorological parameter correction effect is the best,i.e.,the accuracy of forecast meteorological parameters is improved by about 65.4%.Combining the mapping relationship between meteorological parameters and corrected atmospheric refractive index(CARI),and the transition mechanism of CARI to duct parameters,a new duct forecasting mechanism is proposed.Due to the high efficiency of numerical model and the accuracy of sounding data,the new duct forecasting mechanism has excellent performance.By comparing the duct forecasting results,the forecasting accuracy of the new duct forecasting model is significantly higher than that of the mesoscale model. | Feng Yuting Gong Haobing Hao Xiaojing Gao Hui Guo Xiangming | 2023 | The Journal of China Universities of Posts and Telecommunications2023，30，4： | 0 |

| 9 | Study of the spatial growth of stimulated Brillouin scattering in a gas-filled hohlraum via detecting the driven ion acoustic wave显示文摘In an experiment performed on the Shenguang-III prototype laser facility, collective Thomson scattering (TS) is used to study the spatialgrowth of stimulated Brillouin scattering (SBS) in a gas-filled hohlraum by detecting the SBS-driven ion acoustic wave. High-quality timeresolved SBS and TS spectra are obtained simultaneously in the experiment, and these are analyzed by a steady-state code based on theray-tracing model. The analysis indicates that ion–ion collisions may play an important role in suppressing SBS growth in the Au plasma;as aresult, the SBS excited in the filled gas region is dominant. In the early phase of the laser pulse, SBS originates primarily from the high-densityplasma at the edges of the interaction beam channel, which is piled up by the heating of the interaction beam. Throughout the duration of thelaser pulse, the presence of the TS probe beam might mitigate SBS by perturbing the density distribution around the region overlapping withthe interaction beam. | Chaoxin Chen Tao Gong Zhichao Li Liang Hao Yonggang Liu Xiangming Liu Hang Zhao Yaoyuan Liu Kaiqiang Pan Qi Li Sanwei Li Zhijun Li Sai Jin Feng Wang Dong Yang | 2024 | Matter and Radiation at Extremes2024，9，2： | 0 |
| 10 | The effects of incident light wavelength difference on the collective stimulated Brillouin scattering in plasmas显示文摘The first laser–plasma interaction experiment using lasers of eight beams grouped into one octad has been conducted on the Shenguang Octopus facility.Although each beam intensity is below its individual threshold for stimulated Brillouin backscattering(SBS),collective behaviors are excited to enhance the octad SBS.In particular,when two-color/cone lasers with wavelength separation 0.3 nm are used,the backward SBS reflectivities show novel behavior in which beams of longer wavelength achieve higher SBS gain.This property of SBS can be attributed to the rotation of the wave vectors of common ion acoustic waves due to the competition of detunings between geometrical angle and wavelength separation.This mechanism is confirmed using massively parallel supercomputer simulations with the three-dimensional laser–plasma interaction code LAP3D. | Qiang Wang Zhichao Li Zhanjun Liu Tao Gong Wenshuai Zhang Tao Xu Bin Li Ping Li Xin Li Chunyang Zheng Lihua Cao Xincheng Liu Kaiqiang Pan Hang Zhao Yonggang Liu Bo Deng Lifei Hou Yingjie Li Xiangming Liu Yulong Li Xiaoshi Peng Zanyang Guan Qiangqiang Wang Xingsen Che Sanwei Li Qiang Yin Wei Zhang Liqiong Xia Peng Wang Xiaohua Jiang Liang Guo Qi Li Minqing He Liang Hao Hongbo Cai Wudi Zheng Shiyang Zou Dong Yang Feng Wang Jiamin Yang Baohan Zhang Yongkun Ding Xiantu He | 2023 | Matter and Radiation at Extremes2023，8，5： | 0 |
| 11 | Cytotoxicity of Contact Lens Care Solution to Human Corneal Epithelium in Vitro显示文摘Purpose: To investigate the cytotoxicity of soft contact lens multi-purpose care solutions which are now in common use in China.Methods: The cell culture method was used. Cytotoxicity was indicated by significant increases in the number of dead cells relative to controls.Results: Cells were exposed to soft contact lens care solutions for 15 min. They were irregular in shape and variable in size. The intercellular space increased and variable in size.The in-tercelluar space increased and the cells became scrunken. With the time of exposure elongated , damage of cells became more severe.Conclusions: Four kinds of soft contact lens multi-purpose care solutions may have harmful effects on the culture of human corneal epithelial cells. Soaked lenses should be rinsed with saline before being placed in the eyes in order to reduce the potential toxicity of contact lens care solutions.
