Dynamic functional connectivity analysis of Taichong (LR3) acupuncture effects in various brain regions

The present study conducted a multi-scale dynamic functional connectivity analysis to evaluate dynamic behavior of acupuncture at Taichong （LR3） and sham acupoints surrounding Taichong Results showed differences in wavelet transform coherence characteristic curves in the declive, precuneus, postcentral gyrus, supramarginal gyrus, and occipital lobe between acupuncture at Taichong and acupuncture at sham acupoints. The differences in characteristic curves revealed that the specific effect of acupuncture existed during the post-acupuncture rest state and lasted for 5 minutes.

Brain activation and inhibition after acupuncture at Taichong and Taixi: resting-state functional magnetic resonance imaging

Acupuncture can induce changes in the brain. 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.

针刺太冲穴对肝阳上亢型偏头痛大鼠血清血管活性物质含量的影响

目的:探讨针刺太冲穴对肝阳上亢型偏头痛模型鼠的作用机制。方法:将50只SD大鼠随机分为空白对照组(n=10)、模型组(n=40),模型组大鼠以附子汤灌胃结合颈肩部皮下注射硝酸甘油建立肝阳上亢偏头痛模型,其中30只大鼠成模,将成模的大鼠随机分为模型组、太冲组、非穴组,每组10只。太冲组针刺双侧太冲穴,非穴组针刺双侧肋下非穴,留针30 min。观察大鼠行为学(耳红持续时间、挠头及爬笼次数)、酶联免疫吸附试验法检测大鼠血清降钙素基因相关肽(CGRP)、5-羟色胺(5-HT)、肿瘤坏死因子-α(TNF-α)含量。结果:模型组、太冲组及非穴组均在注射硝酸甘油后4 min左右耳红,持续3 h左右消失;与模型组、非穴组比较,太冲组大鼠耳红持续时间较短(均P<0.05)。针刺前,除空白对照组外,大鼠的挠头、爬笼次数增加且组间差异无统计学意义(P>0.05);针刺后1 h、2 h,与模型组和非穴组比较,太冲组大鼠挠头、爬笼次数均减少(均P<0.05)。与空白对照组比较,模型组大鼠血清中CGRP、TNF-α含量增高(P<0.05),5-HT含量降低(P<0.05);与模型组和非穴组比较,太冲组大鼠血清中CGRP、TNF-α含量减少(均P<0.05),5-HT含量增多(均P<0.05)。结论:针刺双侧太冲穴可缓解偏头痛,其作用机制可能与降低血清中CGRP、TNF-α含量,提高5-HT含量有关。

Effects of Hegu (LI 4) and Taichong (LR 3) on Vascular Dilation and Constriction in Migraine Patients

Hegu （LI 4） and Taichong （LR 3） are the Yuan- Primary acupoints of the Large Intestine and Liver Meridian, and are collectively named as Si Guan （four gates） point.

Effect of Taichong(LR 3) acupuncture in spontaneously hypertensive rats

OBJECTIVE: To evaluate the effects of Taichong(LR3) acupuncture points(acupoints) on the expression of glucose transporter protein 1(GLUT1) in the hypothalamus of spontaneously hypertensive rats(SHRs) as measured by combined positron emission tomography and computed tomography(PETCT).METHODS: Spontaneously hypertensive rats(SHR)were divided into model, Taichong(LR 3) acupuncture, and sham groups. 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.
