0.05).The effect of PC6-PC7 and GB37-GB39 groups was significantly superior to that of SJ4-SJ5,BL25-BL24 and GV20-EX-HN groups in elevating MAP 30 min after bleeding(P<0.05).Compared with model group,heart rate(HR) of PC6-PC7 group was increased significantly 15 min and 30 min after bleeding(P<0.05.).After bleeding,low frequency(LF),LF/high frequency(HF) and very low frequency(VLF) increased apparently.Compared with model group,LF,LF/HF and VLF of PC6-PC7 and GB37-GB39 groups decreased significantly 30 min after bleeding(P<0.05),suggesting a better balancing effect of EA of PC6-PC7 and GB37-GB39 on the activities of sympathetic and vagus nerves.Conclusion EA of different acupoint groups has its own relative specificity in regulating MAP and HR in the rat,and PC6-PC7 EA and GB37-GB39 EA have a better efficacy,which is closely associated with their effects in balancing activities of the autonomic nerve system.

Abstract: Objective To observe the effect of electroacupuncture(EA) of different acupoint groups on mean arterial pressure(MAP) and heart rate variability(HRV)in hypotension rats.Methods A total of 70 Wistar female rats were randomized into model,"Neiguan"(PC 6)-"Daling"(PC 7),"Waiguan"(SJ 4)-"Yangchi"(SJ 5),"Tianshu"(ST 25)-"Wailing"(ST 26),"Dachangshu"(BL 25)-"Qihaishu"(BL 24),"Baihui"(GV 20)-"Qianshencong"(EX-HN),and"Guangming"(GB 37)-"Xuanzhong"(GB 39)groups,with 10 cases in each.Hypotension model was established by bleeding(2.5-3 ml) through carotid artery.Immediately after bleeding,EA(2/15 Hz,1 mA,30 min) was applied to the above-mentioned acupoints of the 6 EA groups.MAP and ECG were recorded,then HRV was analyzed by using software Chart 5.2.1.Results MAP declined significantly after bleeding.Compared with model group,MAP values of PC6-PC7 and GB37-GB39 groups increased significantly 15 min and 30 min after bleeding,and those of ST25-ST26 and GV20-EX-HN groups also increased apparently 30 min after bleeding(P<0.05).No marked effects were observed in EA of SJ4-SJ5 and BL25-BL24 groups(P>0.05).The effect of PC6-PC7 and GB37-GB39 groups was significantly superior to that of SJ4-SJ5,BL25-BL24 and GV20-EX-HN groups in elevating MAP 30 min after bleeding(P<0.05).Compared with model group,heart rate(HR) of PC6-PC7 group was increased significantly 15 min and 30 min after bleeding(P<0.05.).After bleeding,low frequency(LF),LF/high frequency(HF) and very low frequency(VLF) increased apparently.Compared with model group,LF,LF/HF and VLF of PC6-PC7 and GB37-GB39 groups decreased significantly 30 min after bleeding(P<0.05),suggesting a better balancing effect of EA of PC6-PC7 and GB37-GB39 on the activities of sympathetic and vagus nerves.Conclusion EA of different acupoint groups has its own relative specificity in regulating MAP and HR in the rat,and PC6-PC7 EA and GB37-GB39 EA have a better efficacy,which is closely associated with their effects in balancing activities of the autonomic nerve system.
