ABSTRACT
OBJECTIVE@#To observe the characteristics of carotid intima-media thickness (IMT) and cerebral blood flow velocity in patients with mild-to-moderate hypertension, and to evaluate the effects of acupuncture on carotid IMT and blood flow velocity of middle cerebral artery and vertebral-basilar artery.@*METHODS@#A total of 240 patients with mild-to-moderate hypertension who met the inclusion criteria were treated with acupuncture method proposed by academician . The acupoints of Renying (ST 9), Quchi (LI 11), Hegu (LI 4), Zusanli (ST 36) and Taichong (LR 3) were selected. The treatment was given once a day, five times a week for 3 months. The carotid ultrasonography and transcranial color Doppler were performed before treatment and 3 months after treatment to evaluate the improvements of carotid IMT and brain blood flow velocity.@*RESULTS@#Among 175 patients, 94.3% suffered from impaired carotid IMT. After acupuncture intervention, 7.7%-10.9% patients had improved IMT but 4.6%-6.3% had aggravated carotid IMT. There was no significant difference of carotid IMT before and after treatment (>0.05). About 50% patients had abnormal intracranial blood flow velocity; after acupuncture intervention, 27.4%-33.3% patients who had the abnormal blood flow velocity had normal one, but 27.0%-52.5% patients who had normal blood flow velocity had abnormal one. After acupuncture intervention, the low-speed blood flow of MCA, VA and BA in female patients aged 41-60 years and the low-speed blood flow of MCA and VA in female patients aged 61-70 years were significantly improved (all <0.05); the high-speed blood flow of MCA and VA in male patients aged 61-70 years and the high-speed blood flow of VA and BA in female patients aged 41-60 years were significantly decreased (all <0.05).@*CONCLUSION@#Nearly 95% of patients with mild-to-moderate hypertension had carotid IMT, and about 50% had abnormal blood flow velocity of intracranial artery. The present study failed to found significant effects of acupuncture on carotid IMT, but it shows acupuncture can generally improve the low blood flow velocity in women with mild-to-moderate hypertension.
