To observe the effect of needle-retention duration at Baihui (GV 20) and Sishencong (EX-HN 1) on blood pressure in hypertension patients.
Twenty-four patients with essential hypertension were randomly divided into acupuncture group and medication group. For patients of the acupuncture group, single-use sterilized filiform needles were inserted into Baihui (GV 20) and Sishencong (EX-HN 1) and manipulated for about 10 s till "Deqi", and retained for 8 h. Patients of the medication group were treated by oral administration of Nifedipine tablets(20 mg)in the morning. Blood pressure (right brachial artery) was detected 0.5, 2, 4, 6 and 8 h after the treatment respectively.
In comparison with pre-treatment, the systolic pressure levels at the time-points of 0.5, 2, 4, 6 and 8 h after taking Nifedipine in the medication group, and the systolic pressure levels at the time-points of 2, 4 and 6 h after the treatment in the acupuncture group, and the diastolic pressure levels at the time-points of 2, 4, 6 and 8 h in both acupuncture and medication groups were decreased obviously (P<0.05, P<0.01). The effect of acupuncture group was significantly weaker than that of the medication group in lowering systolic pressure at the time-points of 0.5 and 8 h after the treatment (P<0.01). No significant differences were found between the acupuncture and medication groups in lowering systolic pressure at the time-points of 2, 4 and 6 h after the treatment, and in lowering diastolic pressure at the time-points of 0.5, 2, 4, 6 and 8 h after the treatment (P>0.05).
Acupuncture stimulation of Baihui (GV 20) and Sishencong (EX-HN 1) with sustained needle-retention works well in lowering blood pressure in hypertension patients, but is relatively slower and has a shorter period of time in lowering blood-pressure efficacy.
观察百会（GV 20）和四神聪（EX-HN 1）留针时间对高血压患者血压的影响。
将24例原发性高血压患者随机分为针刺组和药物组。针刺组患者采用一次性无菌毫针针刺百会（GV 20）和四神聪（EX-HN 1），行针约10秒至“得气”，留针8小时。药物组患者于早晨口服硝苯地平片（20毫克）。分别于治疗后0.5、2、4、6和8小时检测血压（右肱动脉）。
与治疗前比较，药物组服用硝苯地平后0.5、2、4、6和8小时的收缩压水平，针刺组治疗后2、4和6小时的收缩压水平，以及针刺组和药物组治疗后2、4、6和8小时的舒张压水平均明显降低（P<0.05，P<0.01）。针刺组在治疗后0.5和8小时降低收缩压的效果明显弱于药物组（P<0.01）。针刺组和药物组在治疗后2、4和6小时降低收缩压，以及在治疗后0.5、2、4、6和8小时降低舒张压方面，差异均无统计学意义（P>0.05）。
针刺百会（GV 20）和四神聪（EX-HN 1）并留针，对高血压患者有较好的降压作用，但起效相对较慢，降压疗效维持时间较短。
