RESUMEN
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.
RESUMEN
<p><b>OBJECTIVE</b>To establish a method to determine the underivatized glycine (Gly) and proline (Pro) in vinegar turtle shell.</p><p><b>METHOD</b>An HPLC-ELSD method was conducted on a Prevail C18 column (4.6 mm x 250 mm, 5 microm) with the mobile phase of acetonitrile and 0.7% trifluoroacetic acid solution (containing 5.0 mmol x L(-1) heptafluorobutyric acid), and elution time was 15 min.</p><p><b>RESULT</b>The calibration curves were showed good linearity within the concentration range of 0.14-0.6 g x L(-1). The average recoveries were 101.2% and 102.5%, and RSD were 1.9% and 2.5%, respectively.</p><p><b>CONCLUSION</b>Since this method needs neither the special amino acid analyzer nor derivation of amino acid., it is efficient, simple and accurate., which could be used for quality control of vinegar turtle shell.</p>
