Objective To explore the mechanism of immediate effect regulated by acupuncture on acupoints in patients with migraine without aura(MwoA)during the interictal period.Methods A total of 28 MwoA patients were enrolled and resting-state functional magnetic resonance imaging(rs-fMRI)were performed at baseline and after acupuncture for 30 minutes.Paired t test was used to compare the differences of regional homogeneity(ReHo)and voxel-mirrored homotopic connectivity(VMHC)between two groups.Additionally,the correlation between the changes of rs-fMRI indexes and clinical scores was analyzed.Results In MwoA patients after acupuncture for 30 minutes,the mean regional homogeneity(mReHo)was decreased in the right lingual gyrus and right cere-bellum and was increased in the right middle frontal gyrus,while the z transformation voxel-mirrored homotopic connectivity(zVMHC)was significantly decreased in the bilateral cuneus compared with baseline.There was no significant correlation between imaging data and clinical scales.Conclusion Patients with MwoA after acupuncture for 30 minutes show abnormal ReHo and VMHC in multiple brain regions,which suggest that the mechanism of immediate effect may act through regulating pain-related brain regions.

ObjectiveTo investigate the mechanism of acupuncture in the treatment of chemotherapy-related cognitive impairment （CRCI） of breast cancer based on resting-state functional magnetic resonance imaging （rs-fMRI）. MethodTwenty-five patients with CRCI of breast cancer were included and treated with the acupuncture based on the method of regulating qi and blood， nourishing mind and benefiting intelligence； the selected acupoints included Zusanli （ST 36， bilateral）， Xuehai （SP 10， bilateral）， Tanzhong （CV 17）， Zhongwan （CV 12）， Qihai （CV 6）， Baihui （GV 20）， Fengfu （GV 16， bilateral）， Xinshu （BL 15， bilateral）， Tongli （HT 5， bilateral）， Zhaohai （KI 6， bilateral）， Yixi （BL 45， bilateral） twice a week， each time interval of 2-3 days， for 8 weeks. The scores of Montreal Cognitive Assessment （MoCA）， Mini-mental State Examination （MMSE）， European Cancer Research and Treatment Organization Quality of Life Questionnaire （EORTC QLQ-C30） were compared before and after acupuncture， and the effectiveness were evaluated by MoCA scale. The patients received rs-fMRI before and after treatment， and used low-frequency oscillation amplitude and functional connectivity （FC） analysis to extract the mean zALFF values of regions of interest such as bilateral anterior cingulate gyrus， bilateral hippocampus， bilateral amygdala， bilateral temporal pole middle temporal gyrus， and bilateral temporal pole supramarginal gyrus for comparison， and used the brain regions with statistically significant differences in the pre- and post-treatment zALFF values as the seed points for the seed-point-based FC Analysis. Correlation analyses were performed between the imaging metrics and the clinical scales. ResultsTwenty-four patients with CRCI of breast cancer completed treatment and follow-up. The zALFF values of the left hippocampus， left amygdala， and left temporal pole temporal gyrus in patients' rs-fMRI decreased after treatment （P＜0.05 or P＜0.01）， and left temporal pole temporal gyrus and right posterior cerebellar lobe FC were elevated （t = -5.169）， and MoCA scale total scores and visuospatial and executive， naming， and delayed recall cognitive scores， MMSE scale total scores， and EORTC QLQ-C30 scale mood scores were significantly higher （P＜0.05 or P＜0.01）. The total effective rate of MoCA was 58.33%. The difference in zALFF values of the left temporal pole middle temporal gyrus before and after treatment was negatively correlated with the MoCA total score （r= -0.499， P = 0.015）， as well as the difference in abstract function （r = -0.498， P = 0.016）. ConclusionThe acupuncture method of regulating qi and blood， nourishing mind and benefiting intelligence can improve the cognitive function of breast cancer patients with CRCI， and its mechanism may be related to improving the functional activities of hippocampus， amygdala and temporal lobe， as well as the functional connections of left temporal pole-temporal middle gyrus and right posterior cerebellar lobe.
