Résumé
Traditional Chinese Medicine massage is a kind of physiotherapy which affects on specific parts of the body surface by means of training to regulate the function of the body to achieve the therapeutic effect. In this work,under positive detection model, the chemical fingerprint of exhaled breath from volunteers before and after receiving Traditional Chinese Medicine massage within m/z 50-1000 were detected by extractive electrospray ionization-mass spectrometry (EESI-MS). And through high resolution mass spectrometry analysis, the metabolites such as epinephrine (m/z 184. 0889), 3-(3-hydroxyphenyl) propionic acid (m/z 167.0615) and L-tryptophan (m/z 205. 0933) were successfully identified. Besides, chemical fingerprints of volunteers before and after receiving Traditional Chinese Medicine massage under different health condition were clearly differentiated via partial least squares discrimination analysis (PLS-DA). The results showed that Traditional Chinese Medicine massage could significantly change the metabolic process of volunteers. Moreover, it further indicated that the established method could provide a real time fashion to follow metabolic changes caused by Traditional Chinese Medicine massage.
