ABSTRACT
Under the guidance of the "Sancai principle", based on the understanding of the etiology and pathogenesis of the imbalance of muscles and bones in bi syndrome of neck region, holistic treatment should be used. The needle-knife release therapy is applied at corresponding acupoints in the three parts i.e. head, neck and back including Tiancai points (Naohu [GV 17] and Naokong [GB 19]), Rencai points (neck Jiaji [EX-B 2]), and Dicai points (Dazhui [GV 14], Quyuan [SI 13] and Tianzong [SI 11]). According to the layers of the lesion's meridians and muscles, the needle-knife is inserted into skin, muscle and bone to relax the tendons and treat bone disorders, and restore the normal mechanical balance of neck.

Atmosphere is regarded to be an important media in the environmental pollution research area. Passive air sampling was one of the effective complementary sampling techniques for the active high volume air sampler in recent decades. A regional scale investigation on the atmospheric polycyclic aromatic hydrocarbons (PAHs) was conducted in the Yangtze River Delta (YRD). Polyurethane foam based passive air samplers were used to collect the atmospheric PAHs from 31 sampling sites in this area. PAHs concentrations ranged from 10.1 ng x m(-1) to 367 ng x m(-3) in this study. The annual average concentration of benzo [a] pyrene (BaP) reached 2.25 ng x m(-3), which was two times higher exceeding the national standard, GB 3095-2012. The atmospheric PAHs during four seasons decreased in the following order: autumn > winter > spring > summer. Larger BaP excessive areas were found in autumn and winter than other seasons. Moreover, an obvious emission of BaP was confirmed during the winter time. Traffic related petroleum combustion, coal and biomass burning, and coke oven were identified as potential sources of atmospheric PAHs, contributing 38.1%, 42.4%, and 19.5%, respectively.
