OBJECTIVE: To observe the therapeutic effect of electroacupuncture (EA) at Quchi (LI 11) on blood pressure and blood plasma catecholamines in the patient of essential hypertension and to investigate the mechanism. METHODS: Sixty cases of essential hypertension were randomly divided into an EA group (n=30) and a control group (n=30). In the EA group, bilateral Quchi (LI 11) were selected; and in the control group, western medicine Nicardipine was taken. The variation of blood pressure and blood plasma catecholamines were examined before and after the treatment. RESULTS: (1) After treatment, there were significant reduction in the levels of systolic blood pressure and diastole blood pressure in both groups (P < 0.01); (2) After treatment, significant reduction in levels of adrenaline and noradrenaline were also found in both groups (P < 0.01), however, no significant differences in the level of dopamine were observed in both groups (P > 0.05); (3) The effective rate of 66.7% in the EA group was similar to that of 70.0% in the control group (P > 0.05). CONCLUSION: Both EA at Quchi (LI 11) and western medicine are able to beneficially regulate blood pressure of patients with essential hypertension through adjusting blood plasma catecholamines.
