The Effects Of Left Kunlun Point (BL60) On ACA Blood Flow Velocity And PI、RI In Lacunar Infartion Patient

Purpose:Acupuncture on the left Kunlun point on lacunar infarction patients with the use of Transcranial Doppler (TCD) ultrasonic instrument as detection method to observe all six reference points for exploring the hemodynamic effects and the influence of bilateral anterior cerebral artery (ACA) blood flow velocity, PI & RI in clinical application of this point in the treatment of ACA’s lacunar infarction.Method:Selected 30 selected patients divided into mixed-sex group, male and female group of 15 cases each. Source derived from Heilongjiang University of Chinese Medicine, Acupuncture II for the period from December 2013 to March 2014. Age 45-65 years, mean age (56±1.94) years,6 cases appeared signs of dysarthria/clumsy hand syndrome,8 cases of pure sensory stroke,16 cases of pure motor stroke. In average, stroke patients discharged between 15-30 days after admitted to hospital. Experiment environment including ambient, temperature and humidity are in constant comfort condition. In this study, we used the same experienced physicians to perform the acupuncture procedures and TCD operators for related professional control to avoid intensity, manipulation and interference disputes leading to the statistical errors and inference differences. Participants in the condition of supine lie, physicians clean the skin around the acupuncture points, acupuncture on the left Kunlun point for a 0.5-0.8 inch in depth, using row needle technique of reinforcing-reducing method, twirling the number of 6 rev/sec line pin for 15 seconds for a total of 90 revolutions. Patients participating in the experiment were asked to supine lie with one side of front temporal region fully exposed to EME instrument of German-made, for TCD operators to capture the frequency data using 7.5MHz of Companion III version. Method of data collection has the device sensor placed closely to participant’s ACA of temporal region, observed the stability in resolution and the most saturated images to be captured as samples, the samples measuring inner depth of 3.0-6.Ocm region to detect the ACA on the change of hemodynamic parameters. After the clarity and stability signal is detected, data collection proceeded with record of acupuncture in the first 10min before the needles insertion, the first moment as the needles inserted (row needle 15s), the second moment during the needles retention of 15min,30min and immediately after needles removed (45min of retention) and 5min lapse after needles removed, all six times points data values of bilateral ACA Vs, Vd, and Vm, RI and PI. These data values are inputted into SPSS statistical software system version 17.0, for analysis and comparison. It is warrant that data with P<0.05 is statistically significant.Result:1. Effect of acupuncture on the left side of the Kunlun points to mixed-gender experimental group Vs, Vd, Vm and PI, RI1.1. Acupuncture on the left side of the Kunlun, the right side of the ACA all time six points of blood flow velocity does not change significantly.1.2. Acupuncture on the left side of the Kunlun and as the needle retained for 30 min, the left side of the ACA hemodynamic parameters Vs, Vm, Vd rise as compared to the first 10 min before needles insertion with Vs, Vm, Vd parameter, the value was statistically significant (P<0.05) yet PI, RI parameters for all six intervals are status quo at all times.2. Effect of acupuncture on the left side of the Kunlun point to the male experimental group’s Vs, Vd, and Vm and PI, RI.2.1. Acupuncture on the left side of Kunlun of all reference time points, the rights side of Male’s ACA hemodynamic parameters does not change significantly with the first 10min before needles insertion.2.2. Acupuncture on the left side of Kunlun of all reference time points, the left side of Male’s ACA hemodynamic parameters does not change significantly with the first 10min before needles insertion.3. Effect of acupuncture on the left side of the Kunlun point to the female experimental group’s Vs, Vd, and Vm and PI, RI.3.1. Acupuncture on the left side of Kunlun, the rights side of Female’s ACA hemodynamic parameters of all reference time point does not change significantly with the first 10min before needles insertion.3.2. Acupuncture on the left side of Kunlun, the left side of Female’s ACA hemodynamic parameters of all reference time point does not change significantly with the first 10min before needles insertion.4. Effect of acupuncture on the left side of the Kunlun point to the male, the female comparison on the influence of Vs, Vd, and Vm, PI, RI.4.1. Acupuncture on the left side of Kunlun, the rights side of the male, the female controlled group’s ACA Vs, Vd, and Vm, PI, RI hemodynamic parameters compared with for both male and female experimental groups does not change significantly at all similar times point in comparison.4.2. Acupuncture on the left side of Kunlun, the left side of the male, the female’s ACA Vs, Vd, and Vm, PI, RI hemodynamic parameters compared with for both male and female does not change significantly at all similar times point in comparison.Conclusion:1. Acupuncture on the left side of Kunlun point with retention time of 30min on the mixed-gender experimental group caused the left side of participant’s ACA blood flow faster but had no effect on the contralateral ACA blood flow velocity, suggesting that when the lacunar infarction detected on the left ACA can select left side Kunlun points for treatment.2. Acupuncture on the left side of Kunlun point on the Male’s ACA hemodynamic parameters at each time points was not found responsible of the bilateral ACA blood flow velocity and PI, RI of change.3. Acupuncture on the left side of Kunlun point on the Female’s ACA hemodynamic parameters at each time points was not found responsible of the bilateral ACA blood flow velocity and PI, RI of change.4. The needle left Kunlun point in bilateral ACA has no obvious difference when comparison groups of both the male, the female controlled groups at the same time points. Therefore, the findings prompted no gender impact consideration in clinical selection of points in treatment of lacunar infarction.
