RESUMO
Objective:To analyze the main chemical constituents of traditional Chinese medicine compound Bushao Tiaozhi capsules by using UPLC-Q-TOF-MS technology. Method:The separation was eluted with Waters CORTECS UPLC C18 column（2.1 mm×150 mm，1.6 μm） in a gradient mode， with methanol-0.1% formic acid as the mobile phase. The column temperature was 40 ℃，the flow rate was 0.24 mL·min-1，and the injection volume was 1 μL. The mass spectrometry condition was X500R QTOF mass spectrometry，the positive and negative electrospray ionization （ESI） was adopted for determine the chromatographic effluent，and the main chromatographic peaks were assigned and distinguished by Q-TOF. Result:A total of 53 chemical constituents were identified by reference confirmation，literature comparison，and high mass spectrometry data analysis. The chemical constituent cluster was composed of 21 flavonoids，10 phenolics，5 monoterpene glycosides，7 diterpene lactones and 10 sesquiterpenes. Furthermore，all of the constituents were surveyed and classified according to their medicinal materials derivation. Among them，the 5 flavonoids components（mangiferin，isoquercitrin，typhaneoside，isorhamnetin 3-O-neohesperidoside，tiliroside）were identified in Microctis Folium for the first time. Conclusion:This study shows that UPLC-Q-TOF-MS technology provides a simple，rapid，and accurate method for the identification of chemical constituents in Bushao Tiaozhi capsules. The identified chemical components mostly cover the main constituents of each medicinal material in the formula，so as to provide a new technological method and theoretical foundation for further defining the pharmacological basis and mechanism of action and optimizing the quality control of Bushao Tiaozhi capsules.
RESUMO
To study the effect of early intervention of liver-soothing and Blood-activating decoction combined with acupuncture in improving neurological functions, depressive symptom and life quality of patients with post-stroke depression, and compare with fluoxetine hydrochloride. Specifically, 63 patients with post-stroke depression were randomly divided into the traditional Chinese medicine (TCM) acupuncture group (31 cases) and the western medicine group (32 cases). On the basis of the conventional treatment of the primary disease, the TCM acupuncture group was treated with liver-soothing and blood-activating decoction and acupuncture, while the western medicine group was treated with fluoxetine hydrochloride for four weeks. In the follow-up visit six months later, scores of HAMD, NIHSS and SS-QOL were observed. The scores of HAMD and NIHSS of both groups were significantly decreased (P < 0.01), while the scores of SS-QOL increased significantly, with a notable difference compared with that before the treatment (P < 0.01). Specifically, the TCM acupuncture group's was superior to the western medicine group (P < 0.05). The study suggests that the early intervention of liver-soothing and blood-activating decoction combined with acupuncture on patients with post-stroke depression has the effect in relieving depression symptom and improving neurological functions, thereby improving their quality of life and prognosis.
