| PurposeAcupuncture in patients with TIA left HT8, at the same time by Transcranial Doppler ultrasound instrument, observe the different time points in acupuncture six Middle Cerebral Artery hemodynamic changes of the parameters in the situation, the needle left HT8 in patients with TIA Middle Cerebral Artery blood velocity in different time points, the influence of PI and RI, provide reference for clinical use of the hole.MethodThe experimental subjects for elderly volunteers, a total of 30 people, with a history of TIA, age between 40-75 years old. Volunteers TIA into standard, and confirmed by TCD ultrasound imaging on the left side of the MCA blood flow speed, Vm:140～160cm/s, Vm:100-120cm/s, on the right side of MCA blood velocity within the normal range, MCA is characteristic and highly suggestive of moderate stenosis, blood vessel diameter decreases 50%～69%.Volunteers to exclude congenital cardiovascular disease, previous stroke with TIA, a variety of reasons (trauma, piercing, etc.) caused by vascular lesions. By selecting Volunteers for 48 hours before the experiment, and in the process of the whole experiment on smoking wine and oral medications, keep enough sleep, avoid because of other factors influence the experimental data, thus to influence the experimental conclusion. Before the experiment to the volunteers on the safety of the experiment, experiment purpose and method steps, consent of the rear can start the test.Experiment time:volunteers to dine in 2 hours, and lay down after 5 minutes, respiration, pulse and blood pressure were stable after measurement. Experimental environment:room temperature 24±2℃, air relative humidity (50±5)%, quiet. Partial skin after disinfection, select the left HT8 stab 0.3 0.5 inches,with Qi for degrees, while retaining needles and the needle when the needles to speed the per second twist turn 6turn flat line or flat needle technique for 15 seconds, a total of 90 RPM.Subjects to the supine position, stay calm, head to the side, fully exposed lateral temporal book inspection. Detection using Transcranial Doppler ultrasound diagnostic instrument, choose 2 MHz pulse wave doppler probe on the left and right side of the temporal window, probe and middle cerebral artery, back slightly after saturated in color image sampling, record the acupuncture 5 min before, when the needles are inserted, line the needle 1(15 min), line the needle 2(30 min), out the needle(45min) and needle 5 min after a total of six time point of bilateral middle cerebral artery of Vd, Vs, Vm, PI and RI of the experimental data. Applying experimental data entry version SPSS 17.0 statistics software, the single factor analysis of variance, P< 0.05 indicates a significant difference.Avoid the needle or filling purging methods such as different experimental error, so the line on the subjects of acupuncture and needle technique carries on the system by the same name acupuncturist training after operation; The entire process of TCD detection operation by ultrasound doctors.Result1. Acupuncture in patients with TIA left HT8:(1) different time points on the left side of the MCA Vs, Vd and Vm arguments:line the needle 2 on the left side of the MCA Vs, Vd and Vm values were significantly lower compared with before acupuncture, with statistical significance (P<0.05), other time points of data change had no statistical significance (P>0.05); (2)on the left side of the MCA PI,RI parameters impact:when acupuncture, line the needle 1, line the needle 2, the needle retaining needle and the needle when compared before and after acupuncture, there were no statistical significance (P>0.05).2. Acupuncture in patients with TIA left HT8:(1) for different time points on the right side of MCA hemodynamic parameters influence on acupuncture needle, line the needle 1,2, a line of needle and compared before and after acupuncture needle, there was no significant difference (P>0.05).Conclusion1. Acupuncture in patients with TIA left HT8, while retaining needle for 30 minutes of the left middle cerebral artery blood velocity slows, nothing to do with the left side of the middle cerebral artery vascular elasticity and vascular resistance.2. Acupuncture in patients with TIA left HT8, on the right side of the MCA blood velocity and PI, RI index has no statistical significance. |
