Abstract:
Purpose To explore the application of contrast-enhanced ultrasound in evaluating the local muscle microcirculation before and after acupuncture at Zusanli point in normal people.Materials and Methods A total of 72 healthy volunteers who visited the Department of Ultrasound,the Second Affiliated Hospital of Fujian Medical University from September 2018 to May 2020 were prospectively collected,all subjects performed ultrasound contrast before acupuncture,acupuncture with strongest deqi,and two hours after acupuncture to observe the blood flow perfusion of the microvessels in the tibialis anterior muscle.The pre-selected areas of interest the small arteries,muscle tissues and venules in the middle were analyzed to obtain the time-intensity curve and contrast transit time(CTTs)perfusion parameters.Needle sensation was evaluated using objective scoring criteria for acupuncture combined with moxibustion recipients.Gastrin,plasma gastrin,cholecystokinin,and secretin were measured in all subjects before acupuncture,when acupuncture had the strongest deqi,and two hours after acupuncture.Results ①CTTs of arterial-muscle,muscle-venous and arterial-venous of the tibialis anterior muscle at acupuncture with strongest deqi were significantly shorter than those at before acupuncture and two hours after acupuncture(all P<0.001),and there was no significant difference in CTTs before and after acupuncture and moxibustion(P>0.05);②when acupuncture deqi was strongest,serum gastrin,plasma prokinetics,cholecystokinin,and secretin were significantly increased compared with those before acupuncture and two hours after acupuncture,with statistically significant difference(all P<0.001),while there was no significant difference in these parameters between before acupuncture and two hours after acupuncture(P>0.05);③when acupuncture had the strongest deqi,there were positive correlations between gastrin,plasma prokinetic hormone,cholecystokinin,and secretin values and CTTs of arterial-muscle,muscle-venous,and arterial-venous(r=0.360-0.702,P<0.001).Conclusion Acupuncture of the Zusanli,when it gains the strongest deqi,can cause changes in the microcirculation around the skeletal muscle,leading to a significant shortening of CTTs,and also promotes the secretory function of the gastrointestinal tract.
