Anti-hypertension Effect Of Selecting Taichong (LR3) As The Major Point Plus Its Yuan-source And Collateral Acupoints In Treating Patients Of Primary Hypertention

Objective To observe the anti-hypertension effect of selecting Taichong(LR3)as the major point plus its Yuan-source and Collateral Acupoints on the patients with essential hypertension.To provide clinical basis for the specificity of acupoints compatibility effect and acupuncture treatment of hypertension.Methods According to the inclusion criteria,140 patients with essential hypertension were randomized into five groups,Taichong group,Ligou(LR5)group,a non-acupoint group,Taichong plus Ligou group and Taichong plus non-acupoint group.On the basis of the existing treatment,the acupuncture needles were retained in acupoints for 30 min while the arrival of Qi was achieved,and twirled,lifted and thrust for 1 min in every 10 min,once every other day,3 times a week in 4weeks,12 times in total.The blood pressure was examined before and after the every acupuncture,and the 24h ambulatory BP monitoring was examined before and at the end of the treatment,and 4 weeks after the treatment.Result 1.①Comparison of the effect of systolic blood pressure among the needle retaining time of 1 min and 30 min:On the needle retaining time of 30 min,the reduction of systolic blood pressure and diastolic blood pressure among LR3+LR5 group,LR3 group,LR5 group and LR3+non-acupoint group were statistically significant compared to before(P<0.05);On the needle retaining time of 30 min,the reduction of systolic blood pressure among LR3+ LR5 group,LR3 group,LR5 group and LR3+non-acupoint group were statistically significant compared to those of 1 min(P<0.05);The reductions on the needle retaining time of 30 min were significantly superior to those of 1 min.2.The change of systolic blood pressure after 3 times,6 times,9 times and 12 times of acupuncture treatments:The reduction of systolic blood pressure among LR3+LR5 group,LR3 group,LR5 group and LR3+non-acupoint group were gradually increasing after 9times and 12 times of acupuncture treatments,and the systolic blood pressure of these groups were statistically significant compared to before(P<0.05);The degree of decreasing blood pressure of LR3+LR5 group was obviously higher than LR3 group,LR5 group,non-acupoint group and LR3+non-acupoint group after 6 times、9 times and 12 times of acupuncture treatments(P<0.05);After 12 times of acupuncture treatments,the reduction of systolic blood pressure among LR3+LR5 group,LR3 group,LR5 group and LR3+non-acupoint group were statistically significant compared with non-acupoint group(P<0.05).The largest proportional decreases noted in LR3+LR5 group;the degree of decreasing blood pressure in non-acupoint group was smallest.②The results after 3 times,6 times,9 times,12 times of acupuncture on diastolic blood pressure were as follows:After 12 times of acupuncture treatments,the reduction of diastolic blood pressure among LR3+LR5 group,LR3 group,LR5 group and LR3+non-acupoint group were statistically significant compared to before(P<0.05).3.①By the end of the treatment:In 24h,dynamic change of systolic blood pressure on LR3+LR5 group was significantly different compared with the other groups(P<0.05),and it shows the largest decline on the blood pressure.Diastolic blood pressure among LR3 group,LR3+LR5 group and LR3+non-acupoint group were significantly different compared with non-acupoint group(P<0.05).In day,dynamic change of systolic blood pressure and diastolic blood pressure among LR3+LR5 group,LR3 group,LR5 group and LR3+non-acupoint group was significantly different compared with non-acupoint group(P<0.05),and LR3+LR5 group revealed the largest rate.The decreasing amplitude of adjunct acupuncture points groups and single points groups were better than non-acupoint group in 24ht,day and night.②follow-up studies after the treatment:Systolic blood pressure and diastolic blood pressure change in 24ht and night show significantly different on LR3+LR5 group compared with non-acupoint group(P<0.05),and the blood pressure of every groups increased in various degrees.Conclusion 1.The hypertensive effect after removing acupuncture needles in post-acupuncture long needle retaining time(30min)are more explicit than in long needle retaining time(1min).2.The hypertensive effect of the combination of acupoints(LR3+LR5 group)are better than meridian points.Furthermore,the hypertensive effect of meridian points is more explicit than non-acupoint group.3.Compared with diastolic blood pressure,acupuncture are more effective in hypertensive effect of reducing the systolic blood pressure,and it also has the accumulation effect of time to some extent.The hypotensive effect of acupuncture has Long-term antihypertensive effect.
