Abstract:Objective To explore the curative effect of Xiaotong Pingfeng Decoction on migraine. Methods Between January 2013 and June 2015, 112 patients with migraine with aura were treated in our hospital. According to the random number table method they were divided into observation group (Xiaotong Pingfeng Decoction) and control group (Flunarizine Hydrochloride Capsules). Clinical curative effect, hemorheological parameters and plasma levels of serotonin (5-HT), beta-endorphin (β-EP), calcitonin gene-related peptide (CGRP) and neuropeptide Y (NPY), and adverse reactions were observed and recorded in the two groups. Results In the 56 cases of the bservation group, the total effective rate was 80.36%; while in the 56 cases of the control group, the total effective rate was 62.50%. Before treatment, the migraine integral had no significant difference between the two groups (P >0.05). After treatment, the migraine score of the observation group was significantly lower than that of the control group (P < 0.05). Before treatment, hemorheological parameters of the two groups were not significantly different (P >0.05). After treatment, blood viscosity, hematocrit and fibrinogen levels in the observation group were significantly lower than those in the control group (P < 0.05), but there was no significant difference in platelet between the two groups (P > 0.05). Before treatment, there was no significant difference in 5-HT, β-EP, CGRP or NPY level between the two groups (P > 0.05). After treatment, 5-HT, β-EP and CGRP levels of the observation group were significantly higher than those of the control group (P < 0.05), while NPY level was lower than that of the control group (P < 0.05). In the observation group, there were weakness in 1 case, drowsiness in 2 cases, nausea and vomiting in 2 cases, and thirst in 1 case, the overall incidence of adverse reactions was 10.71%; in the control group, there were fatigue in 4 cases, sleepiness in 4 cases, nausea and vomiting in 3 cases, rash in 1 case, and thirst in 3 cases, the total rate of adverse reactions was 26.79%, the difference was statistically significant (P < 0.05). Conclusions Xiaotong Pingfeng Decoction can significantly improve hemorheology in patients with migraine, increase serotonin,β-EP and CGRP levels, avoid excessive secretion of NPY, and further reduce the incidence of adverse reactions.
