Abstract
OBJECTIVE: To verify the efficacy of primary hypertension treated with acupuncture at acupoints selected according to syndrome differentiation and probe into the mechanism of acupuncture for primary hypertension. METHODS:One hundred and thirty-five cases of primary hypertension were randomized into an observation group (108 cases) and a control group (27 cases). In either group, Fengchi (GB 20), Quchi (LI 11), Zusanli (ST 36) and Sanyinjiao (SP 6) were selected conventionally. In observation group, on the basis of the acupoints selected above, the supplementary points were selected according to syndrome differentiation in Chinese medicine and the control group was selected main points only, once per day. After 15 days acupuncture, the efficacy and changes in microcirculation of nail fold were observed. RESULTS: The remarkable effective rate and the total effective rate were 29.6% (32/108) and 84.2% (91/108) in observation group respectively, which were superior to 18. 5% (5/27) and 70.4% (19/27) as compared with control group separately (both P < 0.05). After treatment, the microcirculation of nail fold was all improved in two groups, of which blood flow state integral, peripheral capillary loop state integral and the total integral were all improved obviously (all P < 0.05). The improvements in observation group were much more significant than those in control group (all P < 0.05). CONCLUSION:Acupuncture is effective significantly on primary hypertension and the point selection according to syndrome differentiation can improve the efficacy, which is probably relevant with the reduction in the peripheral vascular resistance due to the improvements of microcirculatory state in mechanism.
