ABSTRACT
OBJECTIVE@#To explore the effectiveness and safety of the combined treatment with acupuncture and venlafaxine hydrochloride on depression in terms of the microstructure change of white matter fiber tracts of brain based on diffusion tensor imaging technology (DTI).@*METHODS@#The prospective study design was adopted. All of 60 patients with depression were randomized into an acupuncture-medication group and a medication group, 30 cases in each one. In the medication group, venlafaxine hydrochloride was used, 75 mg per day in the 1st week, 150 mg per day in the 2nd week and 225 mg per day from the 3rd to 6th week. In the acupuncture-medication group, on the base of the treatment in the medication group, acupuncture was combined. Baihui (GV 20) and Yintang (GV 29) were the main acupoints. The supplementary acupoints were selected according to the clinical symptoms of individuals. The needles were retained for 30 min. Acupuncture was provided once every 2 days, 3 times a week. The consecutive 12 weeks of treatment were required in the two groups. Additionally, a normal group was prepared with 30 healthy volunteers. Separately, before treatment, in 2, 8 and 12 weeks of treatment, Hamilton's depression scale (HAMD-17), Beck depression inventory scale (BDI) and the antidepressant side effect scale (SERS) were adopted to evaluate the effectiveness and safety of the two groups. Moreover, before and after 12 weeks of treatment, DTI was adopted to detect the fractional anisotropy score (FA) of each brain region in the patients.@*RESULTS@#After treatment, the scores of HAMD-17 and BDI were all reduced in the two groups (0.05). Compared with the healthy volunteers, FA scores in 6 brain regions changed obviously in the patients with depression, including the white matter of bilateral frontal lobes, splenium of corpus callosum, left cingulated gyrus, white matter of bilateral inferior temporal gyrus, white matter of bilateral inferior parietal lobe and white matter of bilateral deep temporal occipital region separately. Before treatment, the differences in FA scores of these 6 brain regions were not significant statistically between the two groups (>0.05). After treatment, FA scores in the white matter of bilateral frontal lobes, white matter of bilateral inferior temporal gyrus and white matter of bilateral deep temporal occipital region in the acupuncture-medication group were all higher than those in the medication group (<0.05).@*CONCLUSION@#Acupuncture repairs the brain white matter fiber tracts in some brain regions to certain extent and the therapeutic effects are enhanced with the adjuvant medication of venlafaxine hydrochloride.
