• Zhou Mei-sheng 1984 : shen mind; the state of mind; spirit; the Yang energy of the body; men gate; see Yunmen (1.2)
• Shen ( Ricci 4317 ) : les esprits, divinités, génies, divin, l'Esprit suprême, Dieu, principe vital supérieur, vitalité (Guillaume 1995); plusieurs gloses s'affrontent : un phénomène naturel : tourbillon de la foudre et nuées d'orage d'où : expansion, manifestation, renouvellement des puissances célestes ; ou volutes de fumée d'un sacrifice (expression, manifestation qui s'élève vers les divinités). Représentation de mains qui s'opposent pour tendre une corde, symbole de l'alternance des forces naturelles. La recatégorisation de shen par 示, shì, la clé des affaires religieuses (K 113), fait évoluer le sens vers : influx des puissances d'en haut, d'où : puissances célestes, divinités, esprit ; principe vital supérieur, quintessence de l'énergie vitale ; esprit, âme supérieure ; vitalité (Laurent 2000).
• Men ( Ricci 3426 ) : porte, portail, voie d'accès, entrée ou sortie, ouverture, orifice (Guillaume 1995); Cf. 2P , Yunmen (Laurent 2000).

• Jia Yi jing (Guillaume 1995).

• Zhou Mei-sheng 1984 : Shenmen Taoist called the eye Shenmen, the gate for spirit to go in or out.
• Pan 1993 : Il est appelé « Porte du Shen » parce qu'il ouvre le Cœur et soulage la tension mentale.
• Lade 1994 : Le nom fait référence à une “porte” sur le méridien du Cœur, par laquelle on peut atteindre directement l'énergie hôte de l' organe (l'Esprit). Dans le Taoïsme, shen men fait référence aux yeux (qui reflètent la présence et la force de l'Esprit), endroit par lequel l'Esprit entre et sort.
• Laurent 2000 : Le Su Wen définit ce point comme “le palais de la radiance lumineuse”. Shen peut avoir deux sens esprit lié à la pensée ou vitalité se rattachant au yang fondamental ; dans l'expression jing/shen, shen représente le principe d'organisation de la matière vivante, jing étant sa capacité de développement.

Li Dongyuan dit : « Quand le Qi de l'Estomac descend, il y a perturbation du Qi des Cinq Organes et apparition de diverses maladies. Quand le Qi se trouve au niveau du Cœur, on peut piquer Shenmen- 7C, point Shu du Shoushaoyin pour régulariser le Qi et faire qu'il retrouve sa place ». Selon Ling Shu : « “Le Shao yin n'a pas de shu” cela signifie-t-il que le Cœur n'est jamais malade ?

  The modern literatures on the diseases treated with acupuncture at Shenmen (HT 7) were collected. Using literature statistical analysis in bibliometrics, the common compatibility of Shenmen (HT 7) and the disease spectrum were analyzed so as to provide the references of the diseases that can be treated with acupuncture at Shenmen (HT 7). It was found that 39 kinds of diseases and symptoms, mainly nerve system diseases, could be treated with acupuncture at Shenmen (HT 7), including insomnia, depression, anxiety and dementia. Shenmen (HT 7) was seldom used alone. Instead, it was commonly used along with Baihui (GV 20), Sanyinjiao (SP 6), Neiguan (PC 6), sishencong (EX-HN 1) and Taicong (LR 3).

  The indications of acupoints are thought to be highly associated with the lines of the meridian systems. The present study used data mining methods to analyze the characteristics of the indications of each acupoint and to visualize the relationships between the acupoints and disease sites in the classic Korean medical text Chimgoogyeongheombang. Using a term frequency-inverse document frequency (tf-idf) scheme, the present study extracted valuable data regarding the indications of each acupoint according to the frequency of the cooccurrences of eight Source points and eighteen disease sites. Furthermore, the spatial patterns of the indications of each acupoint on a body map were visualized according to the tf-idf values. Each acupoint along the different meridians exhibited different constellation patterns at various disease sites. Additionally, the spatial patterns of the indications of each acupoint were highly associated with the route of the corresponding meridian. The present findings demonstrate that the indications of each acupoint were primarily associated with the corresponding meridian system. Furthermore, these findings suggest that the routes of the meridians may have clinical implications in terms of identifying the constellations of the indications of acupoints.

The visualization of the indications of the acupoints on a body map. Eight Source points representing the three meridian systems (Foot-Yin, Hand-Yin, and Hand-Yang meridian) and the indications of each acupoint (tf-idf value)were visualized on a human body template (Jung 2015).

  In the previous study, acupuncture at HT7 has shown to attenuate the self-administration of morphine at a low dose (0.1mg/kg). In this study, it was further investigated whether acupuncture at HT7 could attenuate the morphine self-administration at a high dose (0.5mg/kg). Male Sprague-Dawley rats weighing 270-300g were used. After surgery of catheterization, animals were trained to self-administer morphine solution (0.5mg/kg) using daily 1h session under fixed ratio 1 schedule for 3 weeks. Animals that had shown stable morphine-taking (establish baseline: variation less than 20% of the mean of three consecutive days) were subjected to the acupuncture treatment. Bicuculline and SCH 50911 were used to investigate the possible relation between the effect of acupuncture and the GABA receptor system. Acupuncture at HT7, but not at control acupoint, LI5, suppressed spontaneous morphine-taking behavior significantly. In addition, the effect of acupuncture was blocked by both GABA receptor antagonists. The results of this study suggest that acupuncture at HT7 suppresses morphine-taking behavior through the mediation of GABA receptor system.

  We adopted the horseradish peroxidase (HRP) method probe into the segmental distributions of the afferent neurons of the heart and P6, P5 and H7. 10% HRP 50-60µl was injected into P6 of 10 cats, the P5 of 10 cats, H7 of 10 cats and 100-150µl injected into the epicardium and the myocardium of 20 others. The labelled neurons were discovered in the dorsal ganglions in C5-8 and T2 when HRP injected into P6, in C6-8 and T2 when HRP injected into P5, in C6-T2 when HRP injected into H7 and in C8-T1-10 when HRP injected into the epicardium and the myocardium. The experiment showed that there are mutual intersect and overlapping in the C8-T2 spinal ganglions between the afferents of the points and the heart. It may be the neuroanatomical foundations of acupuncture of P6, P5 and H7 for treatment the heart diseases. It also provides the neuroanatomical foundation for somato-visceral connections.

  In order to probe into the therapeutic effect and the mechanism of acupuncture and moxibustion for treatment of coronary heart disease, 60 cases that accorded with diagnostic criteria of coronary heart disease established by WHOM were randomly assigned to two groups. The treatment group received acupuncture at Neiguan (PC 6) and Shenmen (HT7) acupoints and the control group received intravenous drip of polarised liquid. The treatment for the two groups was given once a day and 14 days constituted one therapeutic course. GMP-140, plat and EKG were detected before treatment and after one course respectively. Results showed that GMP-140 after treatment was significantly lower than that before treatment in the treatment group (P<0.01), indicating that acupuncture at Neiguan (PC 6) and Shenmen (HT 7) points can inhibit activity of platelet, prevent thrombosis and improve coronary artery hired flow.

  OBJECTIVE: To observe the effect of electroacupuncture (EA) of “Shenmen” (HT 7) and “Zhizheng” (SI 7) on cardiac function and electrical activities of the cardiac sympathetic nerve in acute myocardial schemia rabbits. METHODS: Forty livid-blue rabbits were randomly divided into normal control, model, “Shenmen” (HT 7) and “Zhizheng” (517) groups with 10 cases in each group. Acute myocardial ischemia (AMI) model was established by intravenous injection of pituitrin (3 U/kg). Changes of heart rate (HR), maximum rising rate (+dp/dt max) and maximum descending rate (-dp/dt max) of the left ventricular systolic pressure (LVSP), and discharges of cardiac sympathetic nerve (superior cardiac branch) were recorded. EA (2 Hz, 5 V) was applied to bilateral “Shenmen” (HT 7) and “Zhizheng” (SI 7) for 30 mm. RESULTS: After AMI, HR, LVSP, +dp/dt max and firing frequency of cardiac sympathetic nerve decreased significantly (P < 0.01), and -dp/dt max increased obviously in model group (P < 0.01). Compared with model group, HR, +dp/dt max and cardiac sympathetic discharge of HT7 and S17 groups increased significantly 10 mm and 20 mm after EA (P < 0.05, 0.01), and -dp/dt max of the later 2 groups reduced evidently 20 mm after EA (P < 0.05, 0.01). No significant differences were found between HT7 and control groups in HR, LVSP and the firing frequency of cardiac nerve 20 mm and 30 mm after EA, and between SI7 and control groups in the firing frequency of cardiac nerve 30 mm after EA (P > 0.05). The effects of group HT7 were significantly better than those of SI7 (P < 0.05). CONCLUSION: EA of both HT7 and SI7 can obviously improve cardiac function and electrical activity of cardiac sympathetic nerve in AMI, and the effects of HT7 are markedly better than those of SI7.

[Effects of Electroacupuncture Stimulation of “Neiguan” (PC 6) and “Shenmen” (HT 7) on Contents of 5-Hydroxytryptamine in Hypothalamic Paraventricular Nucleus Region and Serum in hyperlipidemia rats with acute myocardial infarction]. Acupuncture Research. 2013;38(6):482-7. [164571].

  OBJECTIVE: To observe the effects of electroacupuncture (EA) stimulation of “Neiguan”(PC 6) and “Shenmen” (HT 7) on 5-hydroxytryptamine (5-HT) levels in the paraventricular nucleus (PVN) region of hypothalamus and serum in hyperlipidemia rats with acute myocardial infarction (AMI). METHODS: A total of 80 SD rats with hyperlipidemia were used in the present study. Among them, 20 rats were randomly selected to be the sham-operation group, and the rest 60 cases were used to make the AMI model by occlusion of the anterior descending branch of the left coronary artery. The 60 rats who were identified to be successful in AMI were randomly divided into model group, EA-PC 6 group and EA-HT 7 group (20 rats/group). EA (2 Hz, 2 mA) was applied to bilateral PC 6 and HT 7 for 20 min, once daily for 5 days. The contents of 5-HT of hypothalamic PVN region and serum were examined by enzyme linked immunosorbent assay (ELISA) and radioimmunoassay, respectively. RESULTS: Following AMI, marked myocardial injury (swelling, breakage, disappearance of local transverse striations and necrosis of myocytes) with infiltration of neutrophil granulocytes was found in the model group, while in both EA-PC 6 group and EA-HT 7 group, moderate swelling (no breakage) of fewer myocardial fibers with mild infiltration of neutrophil granulocytes was found, indicating a marked improvement of myocardial injury after EA treatment. Compared with the sham-operation group, the content of 5-HT was obviously decreased in the hypothalamic PVN region and significantly increased in serum in the model group (P < 0.01). After EA intervention, the content of 5-HT was considerably up-regulated in the hypothalamic PVN region and apparently down-regulated in serum in both EA-PC 6 and EA-HT 7 groups in comparison with the model group (P < 0.01). No significant differences were found between EA-PC 6 and EA-HT 7 groups in regulating hypothalamic and serum 5-HT levels (P > 0.05). CONCLUSION: EA stimulation of both PC 6 and HT 7 can relieve acute ischemic injury of the myocardium in hyperlipidemia rats, which is probably partially related to its effect in promoting the release of 5-HT from the hypothalamic PVN region.

Histological changes of myocardial tissues of rats in each group : de gauche à droite : 1) Sham-operation group: normal cardiac myocytes with clear nuclei, and normal myocardial fibers aligning in good order with uniform dyeing. 2) Model group: cardiac myocyte being swelling , necrosis , with swollen myofibrillar degeneration and necrosis with infiltration of neutrophil granulocytes and interstitial edema. 3) EA-PC 6 group: there were little swellings of the myocardial fibers with no breakage and rare infiltration of neutrophil granulocytes. 4) EA-HT 7 group: like the EA-PC 6 group , there were swellings of the myocardial fibers with a little breakage and a small amount of infiltration of neutrophil granulocytes , indicating much improvement resulting from EA treatment.

  OBJECTIVE: To explore the effect of acupuncture at HT7 on heart rate variability (HRV) in healthy volunteers. METHODS: 120 subjects were divided into four groups using a random number table. The following groups of acupuncture interventions were used: HT7 verum acupuncture; HT7 non-penetrating sham acupuncture; acupuncture at a sham point; and no acupuncture. HRV was recorded 10 min before, during and after each stimulation using an Actiheart ECG recorder. RESULTS: The HT7 verum acupuncture group had higher very-low frequency, low frequency and high frequency components of HRV compared with the control groups during but not after acupuncture. The HT7 verum acupuncture group also had higher SD of normal intervals compared with the sham needling and no acupuncture control groups. CONCLUSIONS: Our preliminary study suggests, subject to limitations, that acupuncture at HT7 could affect cardiac autonomic neural regulation in healthy subjects, manifest as increased HRV, most likely via the parasympathetic system.

  OBJECTIVE: To compare the relative characteristics of Baihui (GV 20), Shuigou (GV 26) and Shenmen (HT 7) in treatment of vascular dementia. METHODS: Fifty cases of vascular dementia (VD) were divided into 5 groups randomly. The patients in the group A were treated by acupuncture at routine acupoints. Besides the routine acupoints of the group A, Baihui (GV 20), Shuigou (GV 26) and Shenmen (HT 7) were added to treat the patients in group B, C, D, respectively, while Baihui, Shuigou and Shenmen were added to the group E. The clinical symptoms and signs were observed. RESULTS: Baihui and Shenmen can improve memory, orientation, reaction, obstinacy and trance of VD patients. Baihui is good at helping the patients to understand, calculate and adapt the society. Shuigou is good at improvement of sleeping, slow reaction, trance and memory of the patients. The combination of Baihui, Shuigou and Shenmen can generally promote intelligence level and society adaptive ability. CONCLUSION: Baihui, Shuigou and Shenmen have own characteristics in improving clinical signs and intelligence of patients of VD, and the combination of the 3 acupoints has the best effect in treating VD.

  OBJECTIVE: Using methods of clinical scale assessment and cerebral functional imaging to compare the relative specificity of needling acupoints Baihui (DU20), Shuigou (DU26) and Shenmen (HT7) in intervening vascular dementia (VD) in different areas in the brain. METHODS: Fifty patients with VD were randomized into 5 groups. Needling on conventionally used acupoints of hand and foot three Yang-meridians aiming at hemiplegia was applied to the patients in Group A, and needling on DU20 to Group B, on DU26 to Group C, on HT7 to Group D and on all the three to Group E was applied additionally. Assessments of Mini Mental State Examination (MMSE), Activities of Daily Living (ADL) and Family Attitude Questionnaire (FAQ) were made. And the positron emission computerized tomography (PET) and single photon emission computerized tomography (SPECT) examinations were conducted in 5 selected patients from each group before and after treatment. RESULTS: Needling on conventional acupoints plus DU20 could effect the inner temporal system, thalamencephalon system and prefrontal cortical system to improve memory and executive capacity of VD patients; conventional acupoints plus DU26 could effect more to the prefrontal cortical system to obviously elevate the executive capacity; that plus HT7 would reveal an effect similar to but rather weaker than plus DU20, and effect more to memory; and that plus all the three simultaneously could effect rather roundly multiple aspects of the nervous system related to intellectual activities, to elevate the recognition and enhance the executive capacity. CONCLUSION: Needling on various acupoints like DU20, DU26 and HT7 have effects on different brain areas.

  Objective: To observe the effect of needling Baihui (DU20), Shuigou (DU26) and Shenmen (HT7) on glucose metabolism in different regions of the brain in patients with vascular dementia (VD). Method: Ten patients suffering from vascular dementia were divided into 2 groups randomly. Patients in the control group received needling treatment at the routine acu-points for hemiplegia (acu-points were chosen from the 6 Yang Meridians of the Hand and Foot). Patients in the treatment group received the same treatment with the addition of 3 acupoints chosen especially to treat dementia: Baihui (DU20), Shuigou (DU26) and Shenmen (HT7). All of the patients were examined by positron emission tomography (PET) in order to detect the glucose metabolism in different regions of the brain before and after acupuncture treatment. A semi-quantitative analysis was used to compare the average glucose metabolisms of different cerebral regions of interest before and after treatment. Result: The addition of the 3 acu-points, Baihui (DU20), Shuigou (DU26) and Shenmen (HT7), obviously increased the glucose metabolism of VD patients in the bilateral frontal lobes and thalamus, temporal lobe and lentiform nucleus in the healthy side. Conclusion: The effect of treating VD by needling Baihui (DU20), Shuigou (DU26) and Shenmen (HT7) has a close relationship with its ability to improve cerebral glucose metabolism.

Result There were no significant differences in comparing the HRV indexes between the two groups before intervention (P>0. 05); while the HRV indexes in the treatment group were superior to that in the control group after intervention (P < (0. 05). HRV indexes were improved after intervention in the treatment group (P<0. 05); ofthe indexes, only SDNN was improved after intervention in the control group (P< 0. 05), and the rest indexes were insignificantly changed (P> 0. 05). Conclusion Electroacupuncture at Neignan and Shenmen can significantly reduce HRV in patients with post-cerebral infarction sequelae.

• Chan J et al. An Uncontrolled Pilot Study of HT 7 for “Stress”. Acupuncture Med. 2002;20(2-3):74-7. [12355].

  Bilateral acupuncture needling at HT7 was an effective method for reducing the rating of 'psychological stress' in 16 out of of a group of 17 volunteers (94%), recruited from staff in a hospice. Ratings were made using the Edinburgh Postnatal Depression Scale (EPDS), which was felt to be the most useful scale of those considered, despite not being validated in this population. Four brief acupuncture sessions were performed at weekly intervals. The greatest fall in the EPDS scores was observed within the first two treatments. At the end of the study, there was an average reduction of 44% in the EPDS scores. Further research is needed, including a suitable control group, to determine whether the effect observed in this study was a specific effect of needling at HT7.

  AIM: Insomnia is a major problem which decreases life quality. Many causes are involved with it and anxiety is often associated. The underlying mechanism is not completely understood, even though different factors seem to be associated. Among them melatonin and its circadian rhythm is thought to have an important role. In addition, acupressure and acupuncture are known to ameliorate insomnia and anxiety, when a specific wrist point is stimulated (HT 7 Shenmen). With these bases, the aim of the present study has been to evaluate the efficacy of an acupressure device, H7-insomnia control, positioned on HT 7 points, during the night, in terms of general health and anxiety levels, together with the evaluation of sleep quality and the urinary melatonin metabolite 6-hydroxymelatonin sulphate determination, in a number of insomniacs. METHODS: Forty patients with insomnia were divided into two groups and randomly received either the H7 or placebo treatments, in a double-blind protocol, for 20 nights. Before and after treatments every subject answered a series of questionnaires (General Health Questionnaire 28 items; State-Trait Anxiety Inventory; Pittsburgh Sleep Quality Index) and collected 24 h urines, divided into two samples of 12 h each. Urinary melatonin metabolite was then determined using a RIA method. RESULTS: Data obtained indicate that the device H7-insomnia control is efficacious to ameliorate quality of sleep and reduce anxiety levels in insomniacs, at a higher extent than in the placebo group. In addition, the 24 hours urinary melatonin metabolite rhythm, obtained at the end of treatment, was considered as being normal in a higher percentage of H7-treated patients, with respect to the placebo group. CONCLUSION: It is plausible to hypothesize that the wrist acupressure device might be considered a valid tool, without adverse effects since it does not contain pharmaceutical products, that is able to naturally ameliorate sleep quality in insomniacs, acting through a not jet completely clarified mechanism, that may involve melatonin.

Efficacy of HT 7 Point Acupressure Stimulation in the Treatment of Insomnia in Cancer Patients and in Patients Suffering from Disorders other than Cancer. Minerva Med. 2008;99(6):535-7. [152501].

  AIM: The induction of sleep would depend on interaction between gabaergic system and the pineal gland through its main hormone melatonin. Until few years ago benzodiazepines were the only drugs effective in the treatment of insomnia. Recently, however, both melatonin and acupressure have appear to be active in sleep disorders. The aim of study was to evaluate the efficacy of HT 7 point acupressure in insomnia. METHODS: The study enrolled 25 patients affected by sleep disorders, 14 of whom had a neoplastic disease. They were treated by HT 7 stimulation for al least two consecutive weeks using a medical device named H7 Insomnia Control. RESULTS: An improvement in the quality of sleep was achieved in 15/25 (60%) patients, with a more evident efficacy in cancer patients (11/14 [79%]). CONCLUSION: This study confirms previous clinical data showing the efficacy of acupressure in the treatment of sleep disorders, particularly in cancer-related insomnia.

  A possible application of acupuncture in alleviating depression-like behavioral changes and regulating serotonin signaling in the prefrontal cortex (PFC) of maternally-separated rat pups was investigated in this study. On postnatal day 15, rat pups were maternally-separated and received acupuncture stimulation at acupoint HT7 or ST36 once a day for 7 days. On postnatal day 21, the tail suspension test was performed and the PFC was harvested. Tissue levels of serotonin (5-HT) and 5-hydroxyindole-3-acetic acid (5-HIAA) were then measured by high-performance liquid chromatography and expression of serotonin transporter (5-HTT) and brain-derived neurotrophic factor (BDNF) were assessed by western blotting. Levels of 5-HT and 5-HIAA were not significantly changed, but the 5-HIAA/5-HT ratio was significantly increased by maternal separation. The immobility time of maternally-separated rat pups was increased, and increased 5-HTT expression and reduced BDNF level were observed in the PFC. But acupuncture stimulation at HT7 alleviated the behavioral change and regulated the changes of 5-HIAA/5-HT ratio, 5-HTT, and BDNF. In conclusion, acupuncture stimulation at HT7 can relieve maternal separation-induced changes, and we propose that regulation of the 5-HIAA/5-HT ratio and of 5-HTT expression by acupuncture stimulation are important acupuncture-induced benefits in this animal model of depression.

  To date, the therapeutic strategy against cognitive impairment in Parkinson's disease (PD) is still not in satisfaction level and requires novel effective intervention. Based the oxidative stress reduction and cognitive enhancement induced by laser acupuncture at HT7, the beneficial effect of laser acupuncture at HT7 against cognitive impairment in PD has been focused. In this study, we aimed to determine the effect of laser acupuncture at HT7 on memory impairment, oxidative stress status, and the functions of both cholinergic and dopaminergic systems in hippocampus of animal model of PD. Male Wistar rats, weighing 180-220 g, were induced unilateral lesion at right substantianigra by 6-OHDA and were treated with laser acupuncture continuously at a period of 14 days. The results showed that laser acupuncture at HT7 enhanced memory and neuron density in CA3 and dentate gyrus. The decreased AChE, MAO-B, and MDA together with increased GSH-Px in hippocampus of a 6-OHDA lesion rats were also observed. In conclusion, laser acupuncture at HT7 can improve neuron degeneration and memory impairment in animal model of PD partly via the decreased oxidative stress and the improved cholinergic and dopaminergic functions. More researches concerning effect of treatment duration are still required.

  Effects of acupuncture at HT7 on glucose metabolism in a rat model of Alzheimer's disease: an 18F-FDG-PET study. Acupunct Med. 2015. [185150]. OBJECTIVE: To explore the effects of acupuncture at HT7 on different cerebral regions in a rat model of Alzheimer's disease (AD) with the application of 18F-2-fluoro-deoxy-D-glucose positron emission tomography (FDG-PET). METHODS: Sixty Wistar rats were included after undergoing a Y-maze electric sensitivity test. Ten rats were used as a healthy control group. The remaining 50 rats were injected stereotaxically with ibotenic acid into the right nucleus basalis magnocellularis and injected intraperitoneally with D-galactose. AD was successfully modelled in 36 rats, which were randomly divided into three groups (n=12 each): the AD group, which remained untreated; the AD+HT7 group, which received 20 sessions of acupuncture at HT7 over 1 month; and the AD+Sham group, which received acupuncture at a distant non-acupuncture point. Total reaction time (TRT) was measured by Y-maze and 18F-FDG-PET scans were conducted on day 1 and 30. PET images were processed with Statistical Parametric Mapping 8.0. RESULTS: Pre-treatment, TRT was greater in all AD groups versus controls (mean±SD 24.10±2.48 vs 41.34±5.00 s). Post-treatment, TRT was shortened in AD+HT7 versus AD+Sham and AD groups (p<0.0001, two-way analysis of variance). Glucose metabolic activity in the hippocampus, thalamus, hypothalamus, frontal lobe, and temporal lobe was decreased in AD rats compared with healthy controls and relatively elevated after HT7 acupuncture. Compared with sham acupuncture, HT7 needling had a greater positive influence on brain glucose metabolism. CONCLUSIONS: Needling at HT7 can improve memory ability and cerebral glucose metabolic activity of the hippocampus, thalamus, hypothalamus, and frontal/temporal lobes in an AD rat model.

  OBJECTIVE: To observe the influence of acupuncture of Shenmen (HT 7) and Yanglao (SI 6) on neuro-images in different cerebral regions in volunteer subjects. METHODS: Twelve healthy young volunteer participants were enrolled in this research. fMRI scans were taken in random order in a block design (one for baseline and two for acupuncture stimulations). During stimulation phase, an acupuncture needle inserted in right HT7 or S16 was twirled at an angle of 180 degrees and a frequency of about 1.5 Hz for 35. 6 ms. Main parameters for fMRI were TR/TE/FA = 3560 ms/50 ms/90 degrees. Acupuncture sensations were evaluated by means of visual analog scale (VAS). The collected images were analyzed by using SPM 2 for exploring inter-group differences in blood oxygen level dependent (BOLD) responses. RESULTS: When manipulating the needle, both the operator and the subject had a feeling of deqi . Increases in BOLD signal (group analysis, corrected, 0.05, K > or =10) were found mainly in right postcentral gyrus of frontal lobe (BA 2, BA 1, BA 43), left inferior frontal gyrus (BA 47), secondarily, in the right inferior parietal lobule (BA 40), right inferior frontal gyrus (BA 44), left superior temporal gyrus (BA 22) and right insula (BA 40) after acupuncture at HT7; and chiefly in left inferior parietal lobule (BA 40), right inferior frontal gyrus (BA 45, BA 46), secondarily in the left middle temporal gyrus and inferior temporal gyrus (BA 37) as well as the left superior frontal gyrus (BA 10) after acupuncture of S16. CONCLUSION: Acupuncture of HT7 and SI6 elicite different BOLD responses in some related cerebral regions.

  OBJECTIVE: To study the central modulation mechanism on the relative specificity of the Heart and Lung Meridians and to provide the experimental evidence for deeply study on correlation between meridian-viscera and brain. METHODS: Ten healthy students in Anhui College of TCM were chosen and a modified block design was adopted. After 32 time points of resting and 32 of rotation needling, then 48 of resting and 32 stimulating, and 16 resting time points, functional imagings were collected at last. All the process would last for 10 min 44 sec. Acupuncture work was finished by one acupuncturist with extensive experience by acupuncture at the left Shenmen (HT 7) or Taiyuan ( LU 8 ) with the disposable sterile stainless steel needle, and uniform reinforcing-reducing method was used with frequency of 1 Hz and depth of 1.0 cm. After the experiment, the sensation of acupuncture and the other feeling or psychic process were inquired and recorded detailedly. These data were analyzed by AFNI software. RESULTS: Acupuncture at Taiyuan ( LU 8 ) could excite the contralateral frontal lobe, apical lobe, cerebral ganglion, VI, VIII areas and inferior semilunar lobule of cerebellum, and restrain bilateral callosal gyrus and homolateral gyrus rectus. Acupuncture at Shenmen (HT 7) could excite the contralateral IV-VIII areas of cerebellum, and homolateral VI, VII areas of cerebellum, and restrain parts of homolateral apical lobe. CONCLUSION: Acupuncture at Shenmen (HT 7) of the Heart Meridian and Taiyuan ( LU 8 ) of the Lung Meridian can excite or restrain different brain areas, indicating that there are relatively specific corresponding brain areas for the Heart Meridian and Lung Meridian.

  OBJECTIVE: To observe the effect of acupunture at Shenmen (HT 7) and Daling (PC 7) on different cerebral functional regions by Functional Magnetic Resonance Imaging (MRI), and discuss the relative specificity of effect of these two acupoints. METHODS: Ten healthy right-handed volunteers were enrolled in this research. Under the scan of fMRI with the pattern of “rest-stimulation-rest-stimulation-rest”, acupuncture stimulation was given at Shenmen (HT 7) and Daling (PC 7) on the right side, and all the data were analyzed with Matlab software and SPM5 package to observe the activated cerebral regions. RESULTS: The activated brodmann areas by acupuncture at Shenmen (HT 7) were mainly BA10 BA13, BA47, BA22 on the left side and BA40 BA44 on the right side, while the activated areas by acupunoture at Daling (PC7) were BA46, BA47, BA22 BA10. BA45 on the left side and BA44 BA9, BA6. BA40 on the right side. CONCLUSION: The activated cerebral functional regions of acupuncture stimulation at Shenmen (HT 7) and Daling (PC 7) are not exactly the same, which indicates that the acupuncture effects of the two acupoints are specific. With the same activated areas of language and cognitive function, the Shenmen (HT 7) specializes in emotion control while the Daling (PC 7) could active the autonomic nerve function area.

  Based on the observation that repeated acu-point stimulation elicits evoked potentials whose latency varies as a result of the stimulus intensity we assessed the evoked potential elicited by ;stimulus of three acupoints (Hegu, Shenmen and Houxi), comparing the results to the potentials produced by median nerve stimulus and nonacupunctural point. Fourteen healthy individuals were studied, and no modifications related to the amount of stimuli were found in the N1-P1 amplitude of the potentials. The Ni latency of the Hegu and Shenmen point potentials increased with the amount of stimuli, until it reached a plateau at around 400 stimuli. It did not vary for Houxi and the nonacupunctural point. We conclude that the somesthesic afference from acupunctural points must involve control circuits that are quantitatively different for each point.

  Acupuncture is a useful irritation therapy clinically. Acupuncture at acupoints is proved to have specific function on human body. Magnetic stimulation is a new kind of stimulating technique of non-invasive, painless and effective. The effect of magnetic stimulation on acupoint is a new subject in recent years. In this paper, the electroencephalogram (EEG) evoked potentials (EPs) of magnetic stimulation by stimulating the acupoint of Shenmen(HT7) are studied. The experiments are divided into four groups: quiet, acupoint stimulation, mock stimulation and mock point stimulation. The EEG EPs are collected and an obvious P150 component is obtained. The amplitudes of P150s are analyzed and compared. The P150s are localized in brain by dipole model and the coronal, sagittal and axial plans are painted and observed. The results show that acupoint stimulation on acupoint of Shenmen(HT7) can evoke stronger nerve activity of somatosensory than stimulation on common surface. The dipole source of acupoint stimulation and common surface stimulation are both focused on the cingulated gyrus which related to somatosensory.

  OBJECTIVE: To investigate the effects of manual acupuncture at Shenmen (HT7) or Taiyuan (LU9) on the attention function of the brain, and to lay an experimental foundation for researching brain function and integration mechanisms of the human brain in relation to acupuncture stimulation. METHODS: Ten healthy young college students were selected as experimental subjects. P3a and P3b potentials were induced by novel stimulation and target stimulation with vision and were observed using Neuroscan event-related potentials system at time windows of ms 330-430 or 400-600 ms for observing the change of intensity distribution of P300 after manual acupuncture at HT7 or LU9. RESULTS: The amplitude of P3a and P3b decreased significantly after manual acupuncture at HT7 or LU9, but the degree of decreases affected by the acupoints was different. The decrease of the amplitude of P3a due to acupuncture at HT7 was more significant than acupuncture at LU9 (P<0.05). CONCLUSION: The attention function of the brain is affected by manual acupuncture at HT7 or LU9 and manual acupuncture at HT7 has a greater influence on the attention function of the brain.

  Comparaison des potentiels évoqués de l'électrostimulation de 7C et 9P (Hu 2013)

  OBJECTIVE: To observe the effect difference of electroacupuncture (EA) stimulation of Shenmen (HT 7) and Taiyuan ( LU 9 ) on P 300 of event-related potentials (ERPs) in volunteer subjects, so as to explore functional specificity of acupoints in processing cerebral information. METHODS: Sixty healthy volunteer college students were randomly and equally divided into Shenmen (HT 7) group and Taiyuan ( LU 9 ) group (30 persons/group). EA (2 Hz, 1 mA) was applied to bilateral Shenmen (HT 7) and Taiyuan ( LU 9 ) for 15 min. The ERPs were acquired by averaging EEG activity following Oddba II auditory tone-double stimuli and brain electrical activity mapping (BEAM) acquired by means of Scan 4.5 collection and analysis system. Data were calculated and analyzed with SPSS 17.0 for Windows. After testing, the subjects were inquired about the perception for acupuncture stimulation and other sensations or psychological activities. RESULTS: Following EA stimulation of both HT 7 and LU 9 , the amplitude of P 300 in the ERPs were significantly decreased in comparison with pre-EA stimulation in the same one group (P < 0.01, P < 0.05). No significant changes were found in the latencies of P 300 after EA stimulation of both HT 7 and LU 9 (P > 0.05). But, EA of HT 7 had a slightly stronger effect in shortening P 300 latency. With regard to the potential intensity distribution of BEAM, there were some differences between HT 7 and LU 9 groups. The high potential responses for HT 7 were found mainly in the occipital lobe, and in the left parietal lobe and the right temporal lobe, whereas those for LU 9 were found to mainly disperse in the left occipital lobe and the parietal lobe. CONCLUSION: EA stimulation of HT 7 and LU 9 has a slight difference on lowering P 300 amplitude of ERPs, and may result in different distribution of the high potential responses in different lobes of the cerebral cortex in healthy subjects. The functional specificity of EA stimulation of different acupoints needs further study.
