The differences in characteristic curves revealed that the specific effect of acupuncture existed during the post-acupuncture rest state and lasted for 5 minutes.展开更多

However, the majority of studies to date have focused on a single acupoint at a time. In the present study, we observed activity changes in the brains of healthy volunteers before and after acupuncture atTaichong （LR3） andTaixi （KI3） using resting-state functional magnetic resonance imaging. Fifteen healthy volunteers underwent resting-state functional magnetic resonance imaging of the brain 15 minutes before acupuncture, then received acupuncture atTaichong andTaixi using the nail-pressing needle insertion method, after which the needle was retained in place for 30 minutes. Fifteen minutes after withdrawal of the needle, the volunteers underwent a further session of resting-state functional magnetic res-onance imaging, which revealed that the amplitude of low-frequency lfuctuation, a measure of spontaneous neuronal activity, increased mainly in the cerebral occipital lobe and middle occipital gyrus （Brodmann area 18/19）, inferior occipital gyrus （Brodmann area 18） and cuneus （Brodmann area 18）, but decreased mainly in the gyrus rectus of the frontal lobe （Brodmann area 11）, inferi-or frontal gyrus （Brodmann area 44） and the center of the posterior lobe of the cerebellum. The present ifndings indicate that acupuncture atTaichong andTaixi speciifcally promote blood lfow and activation in the brain areas related to vision, emotion and cognition, and inhibit brain areas related to emotion, attention, phonological and semantic processing, and memory.展开更多

Additionally, Tokyo Wistar rats were used as the control group. Changes in blood pressure were recorded in different groups of rats before and after the corresponding treatment. Hematoxylin and eosin(HE) staining was used to study basic morphological changes, and immunohistochemistry was used to determine GLUT1 expression in the hypothalamus. Further,PET-CT was utilized to elucidate the antihypertensive mechanism after acupuncture at the Taichong(LR 3) acupoints.RESULTS: PET-CT indicated activation of the hypothalamus. Measurement of blood pressure showed that acupuncture at the Taichong(LR 3) acupoints lowered blood pressure. HE staining did not show any significant pathological changes, although differences in cell number were observed. Immunohistochemical analysis indicated a GLUT1 downregulation in the SHRs of the Taichong(LR 3) acupuncture group after the treatment.CONCLUSION: Acupuncture at Taichong(LR 3) acupoints lowered blood pressure in SHRs, with possible mechanisms being changes in cell number and GLUT1 expression in the hypothalamus.展开更多

Method According to syndrome differentiation, toothache was divided into pathogenic wind-fire type and deficiency-fire type. Twenty patients were treated by needling Tai-chong (LR 3) o! the affected side. Reducing manipulation was performed for toothache due to pathogenic windfire while early-reducing-late-tonifying was performed for toothache due to deficiency-fire type. Results The pain disappearance occurred in 14 cases, improved in 5 cases and no effect in one case. Conclusion Needling Tai-chong( LR 3) was effective for toothache.展开更多

Methods: Sixty cases with chronic hepatic diseases were randomly divided into a Taichong(LR 3) group and a Ququan(LR 8) group, 30 cases in each group, and were respectively treated with electroacupuncture at Taichong(LR 3) and Ququan(LR 8). The blood flow results of the hepatic artery and portal vein by color ultrasonic test were used as the objective indexes, to compare and observe the hemodynamics changes of the hepatic artery and portal vein in the patients before and after EA. Results: After EA, in Taichong(LR 3) group, the average velocity, the lowest velocity, resistance indexes and the highest velocity of blood flow of the hepatic artery, and the highest velocity, average velocity of blood flow of the portal vein, blood flow volume of the portal vein(PVBF), total blood flow volume of the liver(TLBF), and Doppler blood perfusion indexes of the hepatic artery(DPI) were all statistically different from those before intervention(all P<0.05). In Ququan(LR 8) group, the highest velocity,average velocity, lowest velocity and resistance indexes of blood flow of the hepatic artery, and the highest velocity and average velocity of blood flow of the portal vein, and PVBF were significantly different from those before intervention(P<0.05). The TLBF and DPI were significantly different from those before intervention(P<0.01). All various indexes were not statistically different between the two groups. Conclusion: EA at Taichong(LR 3) and Ququan(LR 8) can speed up blood flow velocity of the portal vein, increase PVBF, increase the TLBF, increase the resistance indexes of the hepatic artery, decrease the blood flow velocity of the hepatic artery, and decrease DPI in the liver.展开更多

文摘Objective: To observe the influence of electroacupuncture(EA) at Taichong(LR 3) and Ququan(LR 8) on hepatic hemodynamics in the patients with chronic hepatic diseases. Methods: Sixty cases with chronic hepatic diseases were randomly divided into a Taichong(LR 3) group and a Ququan(LR 8) group, 30 cases in each group, and were respectively treated with electroacupuncture at Taichong(LR 3) and Ququan(LR 8). The blood flow results of the hepatic artery and portal vein by color ultrasonic test were used as the objective indexes, to compare and observe the hemodynamics changes of the hepatic artery and portal vein in the patients before and after EA. Results: After EA, in Taichong(LR 3) group, the average velocity, the lowest velocity, resistance indexes and the highest velocity of blood flow of the hepatic artery, and the highest velocity, average velocity of blood flow of the portal vein, blood flow volume of the portal vein(PVBF), total blood flow volume of the liver(TLBF), and Doppler blood perfusion indexes of the hepatic artery(DPI) were all statistically different from those before intervention(all P<0.05). In Ququan(LR 8) group, the highest velocity,average velocity, lowest velocity and resistance indexes of blood flow of the hepatic artery, and the highest velocity and average velocity of blood flow of the portal vein, and PVBF were significantly different from those before intervention(P<0.05). The TLBF and DPI were significantly different from those before intervention(P<0.01). All various indexes were not statistically different between the two groups. Conclusion: EA at Taichong(LR 3) and Ququan(LR 8) can speed up blood flow velocity of the portal vein, increase PVBF, increase the TLBF, increase the resistance indexes of the hepatic artery, decrease the blood flow velocity of the hepatic artery, and decrease DPI in the liver.
