Study On Cumulative Effect Of Hemodynamics In Pca Withthe Acupuncture On Fenglong(St40)

Purpose:Acupuncture on left ST40of healthy youth, and parameters of TCD were managed to be recorded such as Vs, Vd, Vm, PI and RI at different times.Observe the left ST40acupuncture to bilateral posterior cerebral artery blood dynamics influence, discuss whether ST40acupuncture cumulative effect and the acupuncture security for clinical choosing and LiuZhen time provide experimental data.Method:Select with transcranial doppler ultrasound imaging confirmed the flow of blood to the normal PCA healthy young16, evenly divided between men and women. Always inadvertently cerebrovascular disease or other influence factors of PCA. Check in the first three days to stop smoking, drinking or eating blood vessels are the influence of food and drink. Test subjects take the supine position, turn head on one side, and fully exposed to check on one side of the temporal, with transcranial doppler ultrasound instrument (TCD) sampling depth of6.0～6.5cm, probe in temporal Windows and PCA agent, the color most saturated place sampling. Acupuncture16healthy youth FengLong acupuncture point on the left, the TCD respectively in the top10min, the acupuncture needle to when gas, LiuZhen15min, when the needle, needle out10min after testing on both sides of the posterior cerebral artery systolic blood flow of the biggest (Vs), diastolic blood flow (Vd) maximum speed, the mean blood flow velocity (Vm), beating index (PI) and impedance index (RI). The SPSS17.0package statistical analysis. The standard deviation and measurement data mean differences said, the application of single factor analysis of variance statistical analysis. P<0.05for with a statistical significance.Result1The parameters of TCD Vs, Vd, Vm10min after withdrawing the needle from left ST40[Were84.56±19.72cm/s、39.75±10.15cm/s、56.13±14.73cm/s each] all showed a decline compared with the parameters10min before acupuncture(P<0.05), while other parameters turned out to be almost the same(P>0.05).2. The data of right PCA when left ST40being acupuncured turned out to be the same as10min befor acupuncture(P>0.05)Conclusion:1Acupuncture on left ST40has cumulative effect of declining on Vs, Vd and Vm, while no influence was showed out on PCA of the opposite side, which suggest us not to choose patients ipsilateral blood velocity of PCA slowed down when ST40is chosen to cure diseases.2. Acupuncturing ST40has a negative accumulation effect related to LiuZhen time, suggests us cut down LiuZhen time modestly when acupunturing and pay attention to prevent symptons coursed by the decline of ipsilateral blood velocity of PCA.
