Chinese Medical Journal 2017年第21期130卷 2569-2574页

作者： peng-fei Wen Wan-Shou Guo Qi-Dong Zhang Fu-Qiang Gao Ju-An Yue Zhao-Hui {2.u {2.-Ming Cheng Zi-Rong {2. department of Orthopaedic Surgery Peking University China-Japan Friendship School of Clinical MedicineBeijing 100029China department of Orthopaedic Surgery Center for Osteonecrosis and Joint Preserving and ReconstructionBeijing Key Laboratory of Arthritic and Rheumatic DiseasesChina-Japan Friendship HospitalBeijing 100029China beijing University of Chinese Medicine Beijing 100029China

Background： The lateral pillar of the femoral head is an important site for disease development such as osteonecrosis of the femoral head. The femoral head consists of medial, central, and lateral pillars. This study aimed to determine the biomechanical effects of early osteonecrosis in pillars of the femoral head via a finite element （FE） analysis. Methods： A three-dimensional FE model of the intact hip joint was constructed from the image data of a healthy control. Further, a set of six early osteonecrosis models was developed based on the three-pillar classification. The von Mises stress and surface displacements were calculated for all models. Results： The peak values of von Mises stress in the cortical and cancellous bones of normal model were 6.41 MPa and 0.49 MPa, respectively. In models with necrotic lesions in the cortical and cancellous bones, the von Mises stress and displacement of lateral pillar showed significant variability： the stress of cortical bone decreased from 6.41 MPa to 1.51 MPa （76.0% reduction）, while cancellous bone showed an increase from 0.49 MPa to 1.2. MPa （159.0% increase）; surface displacements of cortical and cancellous bones increased from 52.4 μm and 5{2.μm to 67.9 μm （2..5%） and 61.9 μm （18.8%）, respectively. In addition, osteonecrosis affected not only pillars but also adjacent structures in terms of the von Mises stress and surface displacement levels. Conclusions： This study suggested that the early-stage necrosis in the femoral head could increase the risk of collapse, especially in lateral pillar. On the other hand, the cortical part of lateral pillar was found to be the main biomechanical support of femoral head.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2.1. and ended in June 2.1., and the data have been released to the public as the LAMOST Pilot Data Release in August 2.1.. The regular survey started in September 2.1., and completed its first year of operation in June 2.1.. The LAMOST DR1 includes a total of 12.2.plates containing 2.955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2.are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2.2.4 696 spectra, of which 1 944 32. are stellar spectra, 12.082.are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（12. 52. entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

采用文献资料、案例分析等方法,从价值、问题与路径3个维度对中国现代武术节的发展进行审视。武术节作为现代社会的节庆生产,契合了地方社会发展的需要,构建了武术竞技展演的空间,搭建了武术文化交流的平台。然而,在武术节庆中,还存在武术工具价值过度利用,武术负面形象蔓延,武术节贪大问题突出,武术节信息化建设不足,武术节周期节律不强等节庆隐忧。现代武术节的健康持续发展,还需反哺地域武术,促进地域传统武术的传承发展;科学诠释武术文化,传播武术的正面形象;聚焦地域武术文化,创建富有特色的武术节;加强信息化建设,建立"三位一体"的官方信息传播平台;强化时间节律,周期性务实推进武术节的开展。
