Orthogonal design to sift the optimal parameter of Neiguan acupuncture for cerebral infarction

The individual difference and non-repeatability in acupuncture have not only restricted the devel- opment of acupuncture, but have also affected the specificity of acupoints. The present study used instruments to control needle depth, lifting and thrusting frequency, and the duration of acupuncture. Effects of the quantified acupuncture were observed at Neiguan （PC6） with different stimulation parameters. A frequency of 1, 2, or 3 Hz and duration of 5, 60, or 180 seconds were used to observe cerebral blood flow and ratio of infarct volume recovery. Results showed that stimulation at Neiguan with a frequency of 1 Hz and long duration of 180 seconds or 2/3 Hz and long duration of 5/60 seconds significantly increased cerebral blood flow and decreased the ratio of infarct volume. In- teractions between frequency and duration play a critical role in quantified acupuncture therapy.

Electroacupuncture at the Renzhong (DU 26) and Neiguan (PC 6) acupoints repairs the DNA of nervous tissue supplied by the middle cerebral artery in rats

This study compares the changes of DNA repair in brain tissue dominated by the middle cerebral artery after electroacupuncture at the acupoints of Renzhong （DU 26）, Neiguan （PC 6）, Quchi （LI 11） and Zusanli （ST 36） in rats. In the apurinic/apyrimidinic endonuclease DNA basic group reparative excision experiments, the apurinic/apyrimidinic endonuclease activity of brain tissue increased slightly after electroacupuncture in rats. In the DNA polymerase β （Pol β）experiments, the Pol β ac-tivity of brain tissue increased after electroacupuncture, especially at DU 26 and PC 6. In the DNA ligase experiments, the expression of DNA ligase 1 in brain tissue increased significantly after electroacupuncture. These findings demonstrate increased activity of apurinic/apyrimidinic en-donuclease, Pol β and DNA ligase 1 after electroacupuncture at DU 26 and PC 6. Also, DNA repair in brain tissue supplied by the middle cerebral artery is promoted after electroacupuncture at DU 26 and PC 6, which are more effective than the LI 11 and ST 36 acupoints .

EFFECT OF α_1 AND α_2 RECEPTORS IN THE RABBIT THORACIC SPINAL CORD ON ELECTROACUPUNCTURE AT "NEIGUAN" FOR TREATMENT OF ACUTE MYOCARDIAL ISCHEMIA

In the present paper, the effect of α1 and α2 subtypes of the thoracic spinal cord on electroacupuncture (EA)-induced improvement of ischemic cardiac electrical and mechanical activities was observed in 80 anesthetized rabbits by using ECG-ST, MBP, LVP and dp/dt max as indexes. Results showed that:1) EA at "Neiguan" could significantly improve the electrical and mechanical activities of the ischemic heart; 2) the effect of EA could be enhanced to a certain degree when α1 receptors of the thoracic spinal cord were activated by subarachnoid microinjection of phenylephrine, while it was weakened when α1 receptors were inhibited by microinjection of parison; and 3) activation or inhibition of α2 receptors of the thoracic spinal cord by microinjection of clonidine and yohimbine had no marked influence on the effect of EA in improving electrical activity of the ischemic heart, but when activated,they could weaken the effect of EA in raising MBP; while suppressed, they had no any striking influence on the effect of EA in raising MBP. It suggests that among α-receptors, predominantly α1-receptors participate in the process of EA-induced improvement of performance of ischemic heart.

Effect of acupuncture at Neiguan (PC 6) on cardiac function using echocardiography in myocardial ischemia rats induced by isoproterenol

OBJECTIVE: To investigate the effect of acupuncture at Neiguan(PC 6) on cardiac function using echocardiography in rat models of myocardial ischemia(MI) induced by isoproterenol(ISO).METHODS: Twenty-seven Sprague-Dawley rats were randomly assigned to normal, model, and acupuncture groups. The model and acupuncture groups were given injections of ISO(85 mg/kg) to establish the MI model. After model establishment,the acupuncture group was treated with acupuncture at Neiguan(PC 6) for 30 min. Echocardiography was used to monitor diastolic and systolic function for 30 min starting from the time after the acupuncture needles were removed. Changes in the length of left ventricular internal diameter at end-diastole(LVIDd), length of left ventricular internal diameter at end-systole(LVIDs), the ratio of mitral peak velocity at early diastole and atrial contraction(E/A), ejection fraction(EF), fractional shortening(FS), and stroke volume(SV) were measured.RESULTS: Compared with the model group at 0and 15 min after needles were removed, the means of LVIDd and LVIDs were significantly lower(P <0.01) and E/A, EF, FS, and SV significantly higher(P < 0.01) in the acupuncture group. In the acupuncture group, the means of LVIDd and LVIDs15 min after the needles were removed were significantly higher(P < 0.01) than those at 0 min. The means of E/A, EF, FS, and SV significantly decreased(P < 0.01) from 0 to 15 min in the acupuncture group.CONCLUSION: These findings indicate that acupuncture at Neiguan(PC 6) can affect cardiac function by increasing left ventricular diastolic and systolic function in MI rat models, but the effect only lasts for 15 min.
