First, the relationship between Shénquè （神阙 CV 8） and zang-fu and eight extra meridians stated in the ancient literature explained that the theory of CV 8 as the theoretical core of abdominal acupuncture therapy had literature support and theoretical evidence; second, with emphasis on the diagnosis and treatment based on differentiation of syndromes, four methods for selecting the points, including the ones according to hologram, meridians and collaterals, the Ba-kuo （八 廓） and three energizer, meanwhile, the origin of method selecting the points according to Three Energizer and clinical experience was also addressed; third, some problems about the manipulation of abdominal acupuncture therapy were put forward, such as selection of depth, direction, needle tool, as well as personal ideas and precautions, in order to ensure the clinical effect.展开更多

On this basis, by making use of relevant softwares, it had conducted color abstraction on current typical rural appearance; analyzed the color of rural nature, artificial environment and cultural environment in accordance with international standard of Natural Color System; and then concluded color context of rural appearance. It proposed that color control could be conducted on rural appearance from macroscopic, medium and microcosmic perspective by taking advantage of color planning in new rural appearance construction, so as to build a new rural color system, create modern new rural appearance reflecting regional characteristic and integrating with the natural environment, preserve artificial color of traditional ancient villages, coordinate colors in villages with architectures of different ages, finally realizing reshaping of Chinese people's spiritual hometown.展开更多

Current clinical guidelines for low-back pain recommend acupuncture for CLBP. However, there are very few high-quality acupuncture studies on CLBP in older adults. Clinical acupuncture experts in the American Traditional Chinese Medicine Association(ATCMA) were interested in the recent grant on CLBP research announced by the National Center for Complementary and Integrative Health. The ATCMA experts held an online discussion on the subject of real-world acupuncture treatments for CLBP in older adults. Seven participants, each with more than 20 years of acupuncture practice, discussed their own unique clinical experience while another participant talked about the potential mechanism of acupuncture in pain management. As a result of the discussion, a picture of a similar treatment strategy emerged across the participants for CLBP in older adults. This discussion shows that acupuncture may have complicated mechanisms in pain management, yet it is effective for the treatment of chronic pain involving maladaptive neuroplasticity;therefore, it should be effective for CLBP in older adults.展开更多

It is proposed that the interaction between, or lateral coupling of, meridional circulation systems may serve as the mechanism of the oscillation propagation in a meridional direction.展开更多

The dimensionless parameters mainly involved in this discussion are the relative submerged depth Re/h, relative wave height Rc/Hi, relative rubble size B/D50, relative breakwater width B√ HiL0 and wave breaker index ξ. It indicates that there exist notable differences among the computed results, which mainly originate from the limited experimental conditions and different analytical methods, even though the major tendency keeps similar. It is necessary to conduct more systematic studies to obtain better understanding about the mechanism of wave transmission over submerged breakwaters.展开更多
