He is the current vice president of Chinese Acupuncture Society, the honorary chairman of Shanghai Acupuncture Society, a member of Shanghai Intangible Cultural Heritage Assessment Committee. He used to be the director of Shanghai Municipal Literature Museum of Traditional Chinese Medicine and the director of the Shanghai Information Institute of Traditional Chinese Medicine. He has been engaged in acupuncture clinical and literature research for more than 40 years. He has been to Europe to give lectures and treat patients in clinic for 3 times, and received a favorable evaluation. And he has independently written and edited more than 60 books on acupuncture and traditional Chinese medicine as a chief editor （including English and Japanese versions）, which were published in Beijing, Shanghai, Chongqing, Taipei and Tokyo. He has published nearly 100 papers in both English and Chinese. He has also chaired Shanghai Municipal Public Health Bureau research projects, and participated in a number of projects such as Shanghai Municipal Science and Technology Commission project, the National 973 project. He has accumulated a wealth of clinical experience on acupuncture treamlent tor multiple modem intractable diseases, especially has unique experience on the acupuncture treammnt for stubborn eye diseases.展开更多

In marine environments, understanding surface wind and wave fields and their evolution over time is important for conducting safe and efficient human activities, such as navigation and engineering. This study considers long-term trends in the sea surface wind speed(WS) and significant wave height(SWH) in the China Seas over the period 1988–2011 using the Cross-Calibrated Multi-Platform(CCMP) ocean surface wind product and a 24-year hindcast wave dataset obtained from the WAVEWATCH-III(WW3) wave model forced with CCMP winds. The long-term trends in WS and SWH in the China Seas are analyzed over the past 24 years to provide a reference point from which to assess future climate change and offshore wind and wave energy resource development in the region. Results demonstrate that over the period 1988–2011 in the China Seas: 1) WS and SWH showed a significant increasing trend of 3.38 cm s^(-1)yr^(-1) and 1.52 cm yr^(-1), respectively; 2) there were notable regional differences in the long-term trends of WS and SWH; 3) areas with strong increasing trends were located mainly in the middle of the Tsushima Strait, the northern and southern areas of the Taiwan Strait, and in nearshore regions of the northern South China Sea; and 4) the long-term trend in WS was closely associated with El Ni?o and a significant increase in the occurrence of gale force winds in the region.展开更多
