[Herbs for calming liver and suppressing liver-yang in treatment of migraine with hyperactive liver-yang syndrome and its effects on lymphocyte protein expression: a randomized controlled trial]

OBJECTIVE: To observe the efficacy of herbs for calming liver and suppressing liver-yang in treatment of migraine patients with hyperactivity of liver-yang syndrome and to investigate its effects on the lymphocyte protein expression. This approach may lay a foundation for the further investigation of pathogenic mechanisms in migraine with hyperactive liver-yang syndrome and the curative mechanisms of calming liver and suppressing liver-yang treatment. METHODS: A total of 32 migraine patients with hyperactivity of liver-yang syndrome were randomly divided into treatment group (16 cases) and control group (16 cases). The patients in the treatment group were treated with herbs for calming liver and suppressing liver-yang in accordance with traditional Chinese medicine (TCM) theory and the patients in the control group were treated with Flunarizine Capsules for two courses of treatment. The therapeutic effects, the score of TCM symptom and the changes of headache attack were observed in both groups before and after the treatment. The side effects were also observed in both groups. The level of differential protein expression was analyzed by two-dimensional electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). RESULTS: The herbs for calming liver and suppressing liver-yang had better effects on headache improvement than the Flunarizine Capsules (P<0.01). The cure rates in the treatment and control groups were 87.5% and 7...
