百会、四神聪穴久留针对高血压患者血压的影响

目的:观察百会、四神聪穴留针法及口服硝苯地平缓释片对高血压患者血压的影响,探讨治疗高血压的更优疗法。方法:将24例高血压病患者随机分为针刺组和药物组。针刺组选取百会、四神聪穴,针刺得气后留针8h;药物组早晨口服硝苯地平缓释片20mg。分别于治疗后0.5、2、4、6、8h末测量两组患者右上肢血压,对比两组血压情况。结果:针刺组患者2h末收缩压较治疗前明显降低(P<0.05),4h末收缩压到达最低(P<0.01),6h后收缩压开始回升,于8h末收缩压恢复至针刺前水平(P>0.05);药物组患者于0.5h末开始收缩压较治疗前持续下降(P<0.05,P<0.01),8h末仍见血压缓慢下降(P<0.01);0.5h末及8h末针刺组收缩压高于药物组(P<0.01)。两组舒张压均于治疗后2h开始较治疗前下降,且持续到8h(P<0.05,P<0.01);两组舒张压比较差异均无统计学意义(P>0.05)。结论:百会、四神聪穴留针法降低收缩压起效较慢,维持时间较短;对舒张压的影响与口服硝苯地平缓释片相似。

Effect of acupuncture needle-retention duration at Baihui (GV 20) and sishencong (EX-HN 1) on blood pressure in hypertension patients

Objective To observe the effect of needle-retention duration at Baihui(GV 20)and Sishencong(EX-HN 1)on blood pressure in hypertension patients.Methods 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.Results 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).Conclusion Acupuncture stimulation of Baihui(GV 20)and Si-shencong(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.
