With the development of business of manned spaceflight, the body damage of astronauts on the space en-vironment has received growing concern. Weight loss is the most important cause of various diseases, and the weightlessness muscle atrophy is one of urgent problems to be solved in aerospace medicine. Although there is no concept of weightlessness or weightlessness muscle atrophy in the theory of traditional Chinese medicine (TCM), TCM can grasp the pathogenesis of complex diseases, and provide important theoretical references for the prevention and management of weightlessness diseases, especially weightlessness muscle atrophy. In this paper, TCM Cognition of weightlessness and the pathogenesis of weightlessness muscle atrophy was studied by the sight of TCM theory of qi hoisting. The discussion was made from aspects of circulation of qi and blood, zang-fu function. This work is wished to be beneficial to apply the TCM theory in aerospace medicine.

Phytohormone auxins play important roles in plant growth and development. The primary auxin-response genes can be classified into three major groups: Aux/IAAs, SAURs and GH3s. Significant progress has been made in understanding these gene families by approaches of the functional genomics, molecular genetics and molecular biology. In this review, we focused on the structures, functions and models of the expressional regulation of plant GH3 genes. The interactions in the signal transduction pathways between auxins and other signals mediated by the GH3 genes, the relationship between the GH3 genes and the stress adaptation responses of plants are emphasized.
