肩袖损伤发病多因长期不良习惯导致肩胛骨及肩关节发生位移,骨骼移位使得其附着的肌肉出现过度拉伸或发生痉挛,亦使关节间隙变窄,对关节间隙内通过的肌肉造成挤压或磨损,最终导致肩部的筋骨平衡破坏,骨错筋伤、筋骨失衡。在肩袖损伤的诊疗过程中,应坚持筋骨平衡理念,精确诊断、精准治疗。诊断时,基于肩胛骨的6个活动方向、3种常见位移形式以及3种肌肉的病理状态,在筋、骨两个方面对肩袖损伤进行诊断,明确受损肌肉及其损伤程度,明确肩胛骨位移形式。在精确诊断的前提下,对不同损伤形式的肌肉采用针对性的手法,并选择对应的正骨手法矫正肩胛骨位移,将筋骨平衡观念融入整个治疗过程中,调骨理筋、理气活血,达骨正筋柔、血气调和的状态。

Diagnosis of the ENSO modulation of tropical cyclogenesis over the southern South China Sea using a genesis potential index

Acta Oceanologica Sinica 2012年第5期31卷 54-68页

The modulation of tropical cyclogenesis over the southern South China Sea （SSCS） by the El Nin o- Southern Oscillation （ENSO） is examined in October–December （OND）, when tropical cyclone （TC） activities are most active in this region. The results reveal that there were more TCs formed over the SSCS during La Nin a years and less TCs during El Nin o years. How different environmental factors （including low-level vorticity, mid-level relative humidity, vertical wind shear, and potential intensity） contribute to this influence is investigated, using a genesis potential （GP） index developed by Emanuel and Nolan. Composite anomalies of the GP index are produced for El Nin o and La Nin a years separately, which could account for the changes of TC frequency over the SSCS in different ENSO phases. The degree of contribution by each factor is determined quantitatively by producing composites of modified indices in which only one of the contributing factors varies, with the others set to climatology. The results show that the mid-level relative humidity makes the largest contribution to the ENSO modulation of tropical cyclogenesis over the SSCS. Although warmer sea surface temperatures （SSTs） and larger amount of evaporation from the ocean surface were observed over the SSCS during El Nin o years, anomalous descending motions due to the anomalous Walker circulations inhibited the upward transports of water vapor and led to less moisture contents in the middle troposphere, which suppressed TC formations.

A comparison of summer precipitation structures over the South China Sea and the East China Sea based on tropical rainfall measurement mission

引用

Acta Oceanologica Sinica 2013年第11期32卷 41-49页

作者： li Jiangnan YANG Chaofeng li Fangzhou HE Qihua li weibiao School of Environmental Sciences and Engineering Sun Yat-sen University Zhejiang Sub-bureau of East China Regional Air Traffic Management Bureau of CAAC

The three-dimensional structures of summer precipitation over the South China Sea （SCS） and the East China Sea （ECS） are investigated based on tropical rainfall measurement mission （TRMM）. The primary results are as follows. First, both the convective and stratiform precipitation rates in the SCS are much higher than those of the ECS. The contribution of the convective cloud precipitation to the surface precipitation is primarily over the SCS and the ECS with a proportion of about 70%, but the contribution of convective cloud precipitation is slightly larger in the SCS than the ECS. The contribution of stratus precipitation is slightly larger in the ECS than that in the SCS. Second, the content of cloud particles and precipitation particles in the ECS in June was greater than that in the SCS, while in July and August, the content of cloud and precipitation particles in the ECS was less than that in the SCS. Third, the latent heat profile of the ECS is quite different from that of the SCS. In June, the peak values of evaporation and condensation latent heating rates in the ECS are greater than those in the SCS. In July and August, however, the peak values of evaporation and condensation latent heating rates in the ECS are about 0.05°/h less than those in the SCS.

The structural characteristics of precipitation in Asian-Pacific's three monsoon regions measured by tropical rainfall measurement mission

引用

Acta Oceanologica Sinica 2014年第3期33卷 111-117页

作者： li Jiangnan ZHENG Yanping li Fangzhou GUO Feiyun li weibiao Department of Atmospheric Sciences School of Environmental Science and Engineering Sun Yat-Sen University Meteorological Information Center of Guangdong Province Baiyun District Bureau of Meteorology

The three-dimensional structure of precipitation on a seasonal scale in the Asian-Pacific＇s three monsoon regions is investigated based on the tropical rainfall measurement mission （TRMM） data. The results show that：（1） The maximum seasonal variation of the relative proportional difference of convective precipitation and stratiform rain occurs in the East Asian monsoon region, the second occurs in the Indian monsoon region, and the minimum is in the northwest Pacific monsoon region. In both the northwest Pacific mon soon region and the Indian monsoon region, the convective rain is proportionately larger than stratiform rain in all four seasons. （2） Cloud ice reaches its maximum at around 9 km. Cloud water＇s maximum range is between 3 and 4 km. The large value area of precipitation ice is mainly between 4 and 9 km. The precipi tation water particle is concentrated mostly below 4 km. The largest content is from the ground to 2 km. （3） The most remarkable variance of the content of cloud ice in the Indian monsoon region occurs from spring to winter, and the content of cloud water in the northwest Pacific is always higher than that in the other two regions. （4） The latent heat profile has a similar double-peak structure. The first peak is at 4 km and the second peak is at 2 km. In autumn and winter, the latent heat is higher in the northwest Pacific than in other two regions. In all three regions, the release of the latent heat is higher in summer and autumn than in spring and winter.

Evolution mechanisms of the intraseasonal oscillation associated with the Yangtze River Basin flood in 1998

Science China Earth Sciences 2005年第7期48卷 957-967页

作者： CHEN Guixing li weibiao YUAN Zhuojian WEN Zhiping Department of Atmospheric Science/Center of Monsoon and Environment Sun Yat-Sen University Guangzhou 510275 China Department of Atmospheric Science/Center of Monsoon and Environment Sun Yat-Sen University Guangzhou 510275 China Department of Atmospheric Science/Center of Monsoon and Environment Sun Yat-Sen University Guangzhou 510275 China Department of Atmospheric Science/Center of Monsoon and Environment Sun Yat-Sen University Guangzhou 510275 China

With 1998 NCEP reanalysis data and the linear diagnostic equation for local me- ridional circulation, four main processes and the boundary effects with relatively large contribu- tions to the intraseasonal oscillation of the vertical branches of the East Asian meridional circula- tion are quantitatively identified among all the processes involved in the quasi-primitive equations used in the derivation of the linear diagnostic equation. The numerical results show that the main processes with maximal contributions in the lower latitudes include the latent heating and vertical transports of sensible heat. These processes are mainly associated with the tropical convective activities and result in the low-frequency cyclones in the lower latitudes. The main processes with maximal contributions in the higher latitudes are the horizontal transports of westerly momentum and horizontal temperature advections. These processes are mainly associated with the fluctua- tions in the westerlies and result in the low-frequency cyclones in the higher latitudes. The low-frequency cyclones propagating away from lower latitudes not only interact with those from higher latitudes to enhance the lifting of the moist air in the Yangtze River Basin (YRB), but also leave room for the development of the low-frequency anticyclones over the South China Sea (SCS). The southwesterly in the northwestern quadrant of the SCS anticyclones provides the YRB with abundant moisture. This favorable moisture condition along with the enhanced rising motion in the YRB leads to the extraordinary flood in 1998.
