Hwang SI, Yoon YJ, Sung SH, Cho SJ, Park JK. Acupuncture Treatment for Emotional Problems in Women with Infertility: A Systematic Review and Meta-Analysis. Healthcare (Basel) 2023; 11:2704. [PMID: 37893778 PMCID: PMC10606758 DOI: 10.3390/healthcare11202704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 10/03/2023] [Accepted: 10/06/2023] [Indexed: 10/29/2023] Open
Abstract
This systematic review and meta-analysis aimed to evaluate the efficacy and safety of acupuncture in treating emotional problems in women with infertility. We searched for randomized controlled trials using acupuncture treatment for emotional problems in women with infertility using 11 databases from their inception to 30 June 2023. The control intervention included no treatment, sham acupuncture treatment, and conventional treatment. The primary outcome was emotion-related rating scales, and the secondary outcomes were total effectiveness rate, quality of life, clinical pregnancy rate, and adverse events. Twelve randomized controlled trials involving 1930 participants were included. A meta-analysis of these studies indicated that, as compared to the control treatment, acupuncture significantly improved the State-Trait Anxiety Inventory, Self-rating Anxiety Scale, Amsterdam Preoperative Anxiety and Information Scale, and Self-rating Depression Scale scores, which were the primary emotion-related outcomes. Furthermore, the meta-analysis demonstrated that acupuncture treatment had a significant effect on the clinical pregnancy rate, which was the secondary outcome. No adverse events were reported in any of the studies. Our findings demonstrate the potential of acupuncture for treating emotional problems in women with infertility. However, well-designed and high-quality randomized clinical trials are required to confirm the effectiveness and safety of acupuncture treatment. The protocol of the current study was registered in PROSPERO (registration number: CRD42020166119).

Abstract
Background Major depressive disorder (MDD) exhibits a pronounced occurrence among adolescents, aligning closely with the lifetime prevalence rate of 16.6% observed in adults. It is difficult to treat and prone to recurrence. Acupuncture has shown potential in enhancing treatment effectiveness. Nonetheless, there is a lack of research on the use of intradermal acupuncture (IA) in treating adolescent MDD. Methods This study is a double-blind, randomized controlled trial. A cohort of 120 participants will be assigned randomly to three distinct groups, namely a Selective Serotonin Reuptake Inhibitors (SSRIs)-only group, a sham intradermal acupuncture combined with SSRIs (SIA) group, and an active intradermal acupuncture combined with SSRIs (AIA) group. Hamilton Depression Rating Scale will serve as the primary outcome, while Patient Health Questionnaire-9, Self-Rating Depression Scale, Pittsburgh Sleep Quality Index, and Short Form 36 Questionnaire will serve as secondary outcomes in assessing the amelioration of depressive symptoms in patients. These data will be analyzed using SPSS26.0 software. Results We will assess the efficacy and safety of IA for MDD using commonly employed clinical psychiatric scales. Conclusion The efficacy of IA in treating adolescent MDD may be demonstrated in this study, suggesting its potential for optimizing MDD treatment schemes. Trial Registration ClinicalTrials.gov Identifier: NCT05832619 (April 27, 2023).

Front Neurosci 2022; 16:934752. [PMID: 35958987 PMCID: PMC9361000 DOI: 10.3389/fnins.2022.934752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Accepted: 06/23/2022] [Indexed: 11/13/2022] Open
Abstract
Electroacupuncture (EA) stimulates somatic median afferents underlying P5-6 acupoints and modulates parasympathoexcitatory reflex responses through central processing in the brainstem. Although decreases in blood pressure and heart rate by the neural-mediated Bezold-Jarisch reflex responses are modulated by EA through opioid actions in the nucleus tractus solitarius and nucleus ambiguus, the role of the hypothalamus is unclear. The hypothalamic paraventricular nucleus (PVN) is activated by sympathetic afferents and regulates sympathetic outflow and sympathoexcitatory cardiovascular responses. In addition, the PVN is activated by vagal afferents, but little is known about its regulation of cardiopulmonary inhibitory hemodynamic responses. We hypothesized that the PVN participates in the Bezold-Jarisch reflex responses and EA inhibits these cardiopulmonary responses through the PVN opioid system. Rats were anesthetized and ventilated, and their heart rate and blood pressures were monitored. Application of phenylbiguanide every 10 min close to the right atrium induced consistent depressor and bradycardia reflex responses. Unilateral microinjection of the depolarization blockade agent kainic acid or glutamate receptor antagonist kynurenic acid in the PVN reduced these reflex responses. In at least 70% of the rats, 30 min of bilateral EA at P5-6 acupoints reduced the depressor and bradycardia responses for at least 60 min. Blockade of the CCK-1 receptors converted the non-responders into EA-responders. Unilateral PVN-microinjection with naloxone reversed the EA inhibition. Vagal-evoked activity of the PVN cardiovascular neurons was reduced by 30 min EA (P5-6) through opioid receptor activation. These data indicate that PVN processes inhibitory cardiopulmonary reflexes and participates in EA-modulation of the neural-mediated vasodepression and bradycardia.

Abstract
Posttraumatic stress disorder (PTSD) is a serious mental disorder that can appear after exposure to extreme stress. Acupuncture is an alternative therapy that is widely used to treat various neurodegenerative diseases, as well as cognitive and memory impairments. The aim of this study was to examine whether acupuncture stimulation at a specific acupoint (Shenmen or heart meridian, HT7) could improve memory defects caused by single prolonged stress (SPS) in rats. After exposure to SPS, acupuncture on the HT7 acupoint in male rats was performed, once daily for 21 days. We confirmed that this treatment improved fear memory, cognitive function, and spatial memory by modulating the neuroinflammation and expression of brain-derived neurotrophic factor (BDNF) mRNA in the brain. It also significantly inhibited the activation of proinflammatory cytokines, such as tumor necrosis factor-α and interleukin-1β and the enzyme cyclooxygenase-2 in the brain; it increased the expression of BDNF mRNA in the hippocampus. Our findings provide valuable information concerning the clinical usefulness of acupuncture in the treatment of PTSD.

Enhanced Expectation of External Sensations of the Chest Regulates the Emotional Perception of Fearful Faces. Brain Sci 2021; 11:brainsci11070946. [PMID: 34356181 PMCID: PMC8306575 DOI: 10.3390/brainsci11070946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 07/12/2021] [Accepted: 07/14/2021] [Indexed: 11/20/2022] Open
Abstract
Emotional perception can be shaped by inferences about bodily states. Here, we investigated whether exteroceptive inferences about bodily sensations in the chest area influence the perception of fearful faces. Twenty-two participants received pseudo-electrical acupuncture stimulation at three different acupoints: CV17 (chest), CV23 (chin), and PC6 (left forearm). All stimuli were delivered with corresponding visual cues, and the control condition included visual cues that did not match the stimulated body sites. After the stimulation, the participants were shown images with one of five morphed facial expressions, ranging from 100% fear to 100% disgust, and asked to classify them as fearful or disgusted. Brain activity was measured using functional magnetic resonance imaging during the facial expression classification task. When the participants expected that they would receive stimulation of the chest (CV17), the ratio of fearful to non-fearful classifications decreased compared to the control condition, and brain activities within the periaqueductal gray and the default mode network decreased when they viewed fearful faces. Our findings suggest that bodily sensations around the chest, but not the other tested body parts, were selectively associated with fear perception and that altering external inferences inhibited the perception of fearful faces.

Abstract
OBJECTIVE The purpose of the present study was to investigate the effect of acupuncture on xerostomia in irradiated patients with head and neck squamous cell carcinoma (HNSCC). STUDY DESIGN A preventive, 2-arm, parallel, single-blind trial was performed. Patients with HNSCC (N = 296) were checked for eligibility, and 107 patients were enrolled in the study. The study comprised 1 group that did not receive the intervention (n = 55) and the interventional group that received traditional and auricular acupuncture (n = 52). The primary outcome was the reduction of the patients' xerostomia after treatment. In addition, the secondary outcome was the reduction of anxiety. RESULTS The current acupuncture protocol reduced the xerostomia score and increased saliva volume and density without changing salivary pH. Additionally, acupuncture decreased the Beck Anxiety Inventory (BAI) score after radiation therapy. CONCLUSION Combining traditional and auricular acupuncture reduced xerostomia and increased saliva volume without changing the saliva's pH in irradiated patients with HNSCC. Additionally, the combination of traditional and auricular acupuncture reduced BAI scores.

Abstract
OBJECTIVE To examine the association between traditional Chinese medicine (TCM), preconception health patterns and fertility outcomes. METHODS A community-based prospective cohort study was conducted in China. A total of 3012 newly married women who were willing to conceive within 2 years were enrolled in the study and took National Free Prepregnancy Checkups (NFPC). A reliably structured self-rating scale was used to measure the TCM preconception health patterns of the enrolled women. A 3-year follow-up was conducted to obtain the fertility outcomes, including pregnancy rate, time to pregnancy, spontaneous miscarriage and newborn status. Statistical analyses were conducted using Chi-square or Fisher's exact tests, logistic regression models, general linear models and the Cox proportional hazard model. RESULTS The fertility outcomes showed no statistic correlations to the terms of NFPC in this population. Approximately a half of the women (46.66%) had unhealthy patterns. Women with qi & blood-deficiency (odds ratio [OR] = 35.19, 95% confidence interval [CI] = 1.55-801.15) or qi-stagnation (OR = 4.55, 95% CI = 0.90-23.06) pattern took a longer time to get pregnant, and those with qi-stagnation (OR = 2.05, 95% CI = 1.1-3.82) or yang-deficiency (OR = 1.91, 95% CI = 1.12-3.25) pattern had a higher risk of spontaneous miscarriage. CONCLUSION Three unhealthy TCM patterns during the preconception period might be risk factors for low fecundity or poor pregnancy outcomes. The TCM preconception pattern identification may provide a convenient and effective way to screen for potential pregnancy risks beyond the NFPC. Further, appropriate interventions based on the TCM preconception health patterns are needed to improve quality in women's fecundability and birth outcomes.

Abstract
Objective To observe the effects of electroacupuncture (EA) at different acupoints on the expression of N-methyl-D-aspartate receptor (NMDA receptor ) and behaviors in irritable bowel syndrome (IBS) rats. Methods Wistar rats were randomly divided into blank control group (blank group, n=10) and model preparation group (n=50); experimental rat model of IBS was established by the “neonatal maternal separation and acetic acid enema” combined with “colorectal distension stimulation” method. A total of 50 IBS rats were randomly assigned to five groups of 10 each: model group, Yintang (GV29) group, Neiguan (PC6) group, Tianshu (ST25) group, and Zusanli (ST36) group. Rats in four treatment groups, aged 9 weeks old, were treated with EA by HANS with a sparse-dense wave with a frequency of 2/100 Hz, current of 0.1-0.3mA, and 20 min/stimulation, every other day for a total of 5 sessions. After treatment, the abdominal visceral sensitivity was evaluated by abdominal withdrawal reflex (AWR), and the psychological and emotional behavior of rats were evaluated by the open-field test (OFT). The expression of NMDA receptors in anterior cingulate cortex (ACC) was detected by Quantitative Real-time PCR, and the positive expression of NMDA receptors in colon was detected by immunohistochemistry. Results The IBS rat's abdomen is more sensitive and irritable; NR1, NR2A, and NR2B in ACC and NR1 and NR2B in colon of rats significantly increased in the model group versus the normal group (P<0.01) and were inhibited in all treatment groups (P<0.01, P<0.05). Additionally, NR2A and NR2B in ACC reduced more in GV29 group (P<0.01) than in other treatment groups (P all<0.05) compared with the model group. The expression of NR2B in colon was significantly inhibited in ST36 group (P<0.01) and inhibited in GV29 group and ST25 group (P all <0.05) compared with the model group. And the expression of NR2B in colon was more inhibited in ST36 group than in PC6 group (P<0.01). Conclusions EA at different acupoints could obviously relieve abdominal pain and abnormal behaviors in IBS rats in different degrees of effects. The effect of abdominal pain-relief, from greatest to least, is ST25, ST36, GV29, and PC6, while the effect of relieving abnormal behaviors caused by IBS, from greatest to least, is GV29, PC6, ST36, and ST25. There are significant differences in the expressions of NMDA receptors in ACC and colon among different acupoints. This difference should be related to the location distribution and indications of acupoints.

Abstract
Menopause-related depression devastates women's quality of life after middle age. Previous research has shown that estrogen hormone therapy has serious adverse effects; thus, complementary and integrative therapies have been considered clinically. The present study investigates whether stimulation of an acupoint using a mechanical acupuncture instrument (MAI) can mitigate depression-like behavior caused by estrogen deficiency in ovariectomized (OVX) rats. The animals were divided into Sham OVX, OVX, OVX + Sameumgyo (SP6) and OVX + NonAcu (non-acupuncture point) groups. MAI stimulation significantly increased the total distance traveled in the open-field test and the number of open-arm entries in the elevated plus maze and decreased the duration of immobility in the forced swim test. In addition to this decrease in depression-like behavior, brain-derived neurotrophic factor (BDNF) and neuropeptide Y (NPY) release increased in the hippocampus in response to MAI treatment, but estradiol levels did not recover. Furthermore, microinjection of the BDNF receptor antagonist ANA-12 (0.1 pmol/1 μl) into the hippocampus before MAI stimulation significantly suppressed the recovery of NPY levels. Taken together, these findings indicate that MAI stimulation at SP6 facilitates an estradiol-independent BDNF-NPY cascade, which may contribute to its antidepressant effects in OVX rats, an animal model of menopausal disorders.

Abstract
Acupuncture improves ethanol withdrawal-induced anxiety in rats in an acupoint-dependent manner. Thus, the present study investigated the effects of acupuncture on acute restraint stress- (ARS-) induced anxiety. Male rats were exposed to ARS for 3 h followed by acupuncture at either PC6 (Neiguan), HT7 (Shenmen), or a nonacupoint (tail) once a day for three consecutive days. Five minutes after the third acupuncture treatment, anxiety-like behavior was evaluated in an elevated plus maze (EPM). Additionally, plasma corticosterone (CORT) levels were measured by radioimmunoassay and the concentrations of norepinephrine (NE) and 3-methoxy-4-hydroxy-phenylglycol (MHPG) in the central nucleus of the amygdala (CeA) were determined using high-performance liquid chromatography. Acupuncture at PC6, but not HT7 or a nonacupoint, attenuated anxiety-like behavior, but this attenuation was abolished by a postacupunctural intra-CeA infusion of NE. Acupuncture at PC6 also reduced the oversecretion of plasma CORT and inhibited increases in amygdaloid NE and MHPG induced by ARS. Further, Western blot analyses and real-time polymerase chain reaction assays revealed that acupuncture at PC6 prevented ARS-induced enhancements in the protein and mRNA expressions of tyrosine hydroxylase in the CeA. These results suggest that acupuncture performed specifically at acupoint PC6 reduces ARS-induced anxiety-like behavior by dampening amygdaloid noradrenergic responses.

Abstract
The aim of this work was to investigate if eletroacupuncture at PC6 would modulate the stress-induced anxiety-like behavior and the level of activation of several brain areas. Rats were distributed in groups: control; submitted to immobilization; submitted to immobilization and eletroacupuncture at PC6 or at the tail. Immobilization increased grooming and decreased stretched attend postures and the time spent in the open arms of the ele-vated plus-maze. Eletroacupuncture at PC6 or tail canceled the effect of immobilization on grooming and attenuated the stretched attend posture. Immobilization increased Fos-immunoreactivity in the prefrontal cortex, medial and central amygdala, paraventricular and dorsomedial nuclei of the hypothalamus, lateral hypothalamus, dentate gyrus, CA1, CA2 and CA3 hippocampal areas. The activation of paraventricular, dorsomedial nuclei and prefrontal cortex by immobilization was canceled by electroacupuncture at PC6 and attenuated by electroacupuncture in the tail. The activation of the other areas was canceled by electroacupuncture in PC6 or the tail. It is concluded that immobilization induced anxiety-like behavior that was moderately attenuated by eletroacupuncture with difference between the stimulation in PC6 or the rat tail. Eletroacupuncture showed specificity concerning to the attenuation of the effects of immobilization in the CNS areas related to the stress response, anxiety and cardiovascular system.

Abstract
Objective. The current study is designed to investigate the antidepressant efficacy of electroacupuncture (EA) treatment by evaluating its effect on the synthesis, metabolism, reuptake, and receptors of 5-hydroxytryptamine (5-HT), so as to clarify the molecular mechanisms of EA for antidepression. Materials and Methods. Solitary combined with the chronic unpredictable mild stress (CUMS) was used to establish the rat model with depression. The depressed rats were supplied with EA treatment for 4 weeks, and the behavior change and the following indices including 5-HT, 5-hydroxyindoleacetic acid (5-HIAA), monoamine oxidase A (MAO-A), tryptophan hydroxylase (TPH), 5-HT transporter (SERT), 5-HT1A, and 5-HT2A in hippocampus and prefrontal cortex were examined. Results. EA treatment significantly improved the behavior of rats and increased 5-HT level in hippocampus of depressed rats. Similarly, EA treatment could significantly increase protein and mRNA expression of TPH and 5-HT1A during 5-HT synthesis process in hippocampus of depressed rats. However, EA treatment had no effect on the activity of MAO-A and the expression of SERT protein and mRNA. Conclusion. Antidepressant efficacy of EA treatment can be accomplished through enhancing 5-HT synthesis, upregulating 5-HT1A level, and improving 5-HT content in brain and synaptic gaps.

Abstract
In the present study, we investigated the changes of microRNA (miRNA) expression upon depression and electro-acupuncture (EA) intervention in chronic unpredictable mild stress (CUMS) rats using microarray analysis. Results showed that EA intervention remarkably improved behavioral indexes in terms of crossing number, rearing number, sucrose preference and body weight of CUMS rats. Microarray analysis revealed that a total of 153 differentially expressed miRNAs were regulated by CUMS, and the expression of 180 differentially expressed miRNAs was changed after EA intervention. Among these miRNAs, two miRNAs were significantly up-regulated and four miRNAs were significantly down-regulated by CUMS. Moreover, four miRNAs were significantly up-regulated and 12 miRNAs were significantly down-regulated after EA intervention. The expressions of miR-383-5p and miR-764-5p were up-regulated after CUMS, while their expressions were down-regulated by EA intervention. Further analysis showed that 1260 possible target genes were predicted for miR-383-5p and miR-764-5p, and 97 pathways and 137 gene ontology (GO) were involved. Among these pathways and GO, about 20 pathways and 21 GO were related to depression. Changes of miR-383-5p and miR-764-5p indicated that EA might exert its therapeutic effect on depression through promoting the neurotrophy and inhibiting the abnormal apoptosis of neurons as well as other correlative signal pathways. In conclusion, our present study enriched the understanding of pathological process of depression and revealed possible mechanisms of EA on depression.

Abstract
The paraventricular nucleus (PVN) regulates sympathetic outflow and blood pressure. Somatic afferent stimulation activates neurons in the hypothalamic PVN. Parvocellular PVN neurons project to sympathoexcitatory cardiovascular regions of the rostral ventrolateral medulla (rVLM). Electroacupuncture (EA) stimulates the median nerve (P5-P6) to modulate sympathoexcitatory responses. We hypothesized that the PVN and its projections to the rVLM participate in the EA-modulation of sympathoexcitatory cardiovascular responses. Cats were anesthetized and ventilated. Heart rate and mean blood pressure were monitored. Application of bradykinin every 10-min on the gallbladder induced consistent pressor reflex responses. Thirty-min of bilateral EA stimulation at acupoints P5-P6 reduced the pressor responses for at least 60-min. Inhibition of the PVN with naloxone reversed the EA-inhibition. Responses of cardiovascular barosensitive rVLM neurons evoked by splanchnic nerve stimulation were reduced by EA and then restored with opioid receptor blockade in the PVN. EA at P5-P6 decreased splanchnic evoked activity of cardiovascular barosensitive PVN neurons that also project directly to the rVLM. PVN neurons labeled with retrograde tracer from rVLM were co-labeled with μ-opioid receptors and juxtaposed to endorphinergic fibers. Thus, the PVN and its projection to rVLM are important in processing acupuncture modulation of elevated blood pressure responses through a PVN opioid mechanism.

IL-4 Inhibits IL-1β-Induced Depressive-Like Behavior and Central Neurotransmitter Alterations. Mediators Inflamm 2015; 2015:941413.

Abstract
It has been known that activation of the central innate immune system or exposure to stress can disrupt balance of anti-/proinflammatory cytokines. The aim of the present study was to investigate the role of pro- and anti-inflammatory cytokines in the modulation of depressive-like behaviors, the hormonal and neurotransmitter systems in rats. We investigated whether centrally administered IL-1β is associated with activation of CNS inflammatory pathways and behavioral changes and whether treatment with IL-4 could modulate IL-1β-induced depressive-like behaviors and central neurotransmitter systems. Infusion of IL-4 significantly decreased IL-1β-induced anhedonic responses and increased social exploration and total activity. Treatment with IL-4 markedly blocked IL-1β-induced increase in PGE2 and CORT levels. Also, IL-4 reduced IL-1β-induced 5-HT levels by inhibiting tryptophan hydroxylase (TPH) mRNA and activating serotonin transporter (SERT) in the hippocampus, and levels of NE were increased by activating tyrosine hydroxylase (TH) mRNA expression. These results demonstrate that IL-4 may locally contribute to the regulation of noradrenergic and serotonergic neurotransmission and may inhibit IL-1β-induced behavioral and immunological changes. The present results suggest that IL-4 modulates IL-1β-induced depressive behavior by inhibiting IL-1β-induced central glial activation and neurotransmitter alterations. IL-4 reduced central and systemic mediatory inflammatory activation, as well as reversing the IL-1β-induced alterations in neurotransmitter levels. The present findings contribute a biochemical pathway regulated by IL-4 that may have therapeutic utility for treatment of IL-1β-induced depressive behavior and neuroinflammation which warrants further study.

Acupuncture Affects Autonomic and Endocrine but Not Behavioural Responses Induced by Startle in Horses. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:219579.

Abstract
Startle is a fast response elicited by sudden acoustic, tactile, or visual stimuli in a variety of animals and in humans. As the magnitude of startle response can be modulated by external and internal variables, it can be a useful tool to study reaction to stress. Our study evaluated whether acupuncture can change cardiac autonomic modulation (heart rate variability); and behavioural (reactivity) and endocrine (cortisol levels) parameters in response to startle. Brazilian Sport horses (n = 6) were subjected to a model of startle in which an umbrella was abruptly opened near the horse. Before startle, the horses were subjected to a 20-minute session of acupuncture in acupoints GV1, HT7, GV20, and BL52 (ACUP) and in nonpoints (NP) or left undisturbed (CTL). For analysis of the heart rate variability, ultrashort-term (64 s) heart rate series were interpolated (4 Hz) and divided into 256-point segments and the spectra integrated into low (LF; 0.01–0.07 Hz; index of sympathetic modulation) and high (HF; 0.07–0.50 Hz; index of parasympathetic modulation) frequency bands. Acupuncture (ACUP) changed the sympathovagal balance with a shift towards parasympathetic modulation, reducing the prompt startle-induced increase in LF/HF and reducing cortisol levels 30 min after startle. However, acupuncture elicited no changes in behavioural parameters.

Abstract
Anxiety disorders are among the most common psychiatric illnesses, and acupuncture treatment is widely accepted in the clinic without the side effects seen from various medications. We designed a scalp acupuncture treatment protocol by locating two new stimulation areas. The area one is between Yintang (M-HN-3) and Shangxing (DU-23) and Shenting (DU-24), and the area two is between Taiyang (M-HN-9) and Tianchong (GB-9) and Shuaigu (GB-8). By stimulating these two areas with high-frequency continuous electric waves, remarkable immediate and long-term effects for anxiety disorders have been observed in our practice. The first case was a 70-year-old male with general anxiety disorder (GAD) and panic attacks at night. The scalp acupuncture treatment protocol was applied with electric stimulation for 45 minutes once every week. After four sessions of acupuncture treatments, the patient reported that he did not have panic attacks at night and he had no feelings of anxiety during the day. Follow-up 4 weeks later confirmed that he did not have any episodes of panic attacks and he had no anxiety during the day since his last acupuncture treatment. The second case was a 35-year-old male who was diagnosed with posttraumatic stress disorder (PTSD) with a history of providing frontline trauma care as a Combat Medics from the Iraq combat field. He also had 21 broken bones and multiple concussions from his time in the battlefield. He had symptoms of severe anxiety, insomnia, nightmares with flashbacks, irritability, and bad temper. He also had chest pain, back pain, and joint pain due to injuries. The above treatment protocol was performed with 30 minutes of electric stimulation each time in combination with body acupuncture for pain management. After weekly acupuncture treatment for the first two visits, the patient reported that he felt less anxious and that his sleep was getting better with fewer nightmares. After six sessions of acupuncture treatments, the patient completely recovered from PTSD, went back to work, and now lives a healthy and happy family life. The above cases and clinical observation show that the scalp acupuncture treatment protocol with electric stimulation has a significant clinic outcome for GAD, panic disorder and PTSD. The possible mechanism of action of scalp acupuncture on anxiety disorder may be related to overlapping modulatory effects on the cortical structures (orbitofrontal cortex [OFC]) and medial prefrontal cortex [mPFC]) and subcortical/limbic regions (amygdala and hippocampus), and biochemical effect of acupuncture through immunohistochemistry (norepinephrine, serotonin) performed directly to the brain tissue for anxiety disorders.

Abstract
Recent studies have been conducted to examine the neuroprotective effects of acupuncture in many neurological disorders. Although the neuroprotective effects of acupuncture has been linked to changes in signaling pathways, accumulating evidence suggest the participation of endogenous biological mediators, such as the neurotrophin (NT) family of proteins, specifically, the brain derived neurotrophic factor (BDNF). Accordingly, acupuncture can inhibit neurodegeneration via expression and activation of BDNF. Moreover, recent studies have reported that acupuncture can increase ATP levels at local stimulated points. We have also demonstrated that acupuncture could activate monocytes and increase the expression of BDNF via the stimulation of ATP. The purpose of this article is to review the recent findings and ongoing studies on the neuroprotective roles of acupuncture and therapeutic implications of acupuncture-induced activation of BDNF and its signaling pathway.

Abstract
Extracellular signal-regulated kinase (ERK)-cAMP response element binding protein (CREB) signal pathway has been implicated in the pathogenesis of depression. There is growing evidence that acupuncture in traditional Chinese medicine has antidepressant-like effect. However, the effect of acupuncture on ERK-CREB pathway remains unknown. In our study, the antidepressant-like effect of acupuncture treatment was measured by sucrose intake test and open field test in rats exposed to chronic unpredictable mild stress (CUMS) for 4 weeks. The protein levels of ERK1/2, CREB, phosphorylated ERK1/2 (p-ERK1/2), and phosphorylated CREB (p-CREB) in the hippocampus (HP) and prefrontal cortex (PFC) were examined by Western blot analysis. Our results showed that CUMS rats exhibited the reduction in behavioral activities, whereas acupuncture stimulation at acupoints Baihui (Du20) and Neiguan (PC6) reversed the behavioral deficit. In addition, exposure to CUMS resulted in the decrease of p-ERK1/2 and p-CREB in the HP and PFC. Acupuncture increased the ratio of p-ERK1/2 to ERK1/2 and the ratio of p-CREB to CREB in the HP and PFC. Our study suggested that one potential way, by which acupuncture had antidepressant-like effect, might be mediated by activating the ERK-CREB pathway in the brain.

Abstract
BACKGROUND AND OBJECTIVE Postmortem studies indicate that the number and density of glial cells are reduced in different brain regions of patients with depression. Glial cell line-derived neurotrophic factor (GDNF) plays an important role in the pathogenesis of depressive disorder (DD) and might be a biomarker for damage to nerve cells. In this study, we compared the therapeutic effects of electroacupuncture (EA) and fluoxetine, a serotonin reuptake inhibitor, on DD patients, focusing on the serum level of GDNF. DESIGN This was a prospective, randomized clinical trial. SETTING Seventy-five patients with DD from the Department of Acupuncture, Beijing Hospital of Traditional Chinese Medicine, were recruited. INTERVENTION Twenty patients were treated with acupuncture for 6 weeks on the acupoints of Baihui (DU20) and Zusanli (ST36). Sixteen patients were treated with acupuncture for 6 weeks on the acupoints of Taichong (LR3), Sanyinjiao (SP6), Neiguan (PC6), and Shenmen (HT7), and constituted the electroacupuncture control group. The patients received acupuncture treatment five times per week. Twenty-five patients were treated with oral fluoxetine (20 mg/day) for 6 weeks. OUTCOME MEASURES All subjects were evaluated by the Hamilton Depression Rating Scale at four time points (0 [baseline], 2, 4, and 6 weeks after treatment). Serum GDNF was quantified in duplicate by enzyme-linked immunosorbent assay (ELISA). RESULTS EA and fluoxetine had similar curative effects on DD patients. EA had a faster onset of action, better response rate, and better improvement rate than fluoxetine. Both fluoxetine and EA treatment restored the normal concentration of GDNF in the serum of DD patients. CONCLUSION EA treatment for depression is as effective as a recommended dose of fluoxetine. However, EA demonstrates an advantage in the regulation of the production of GDNF compared with fluoxetine.

DESIGN, SETTING AND SUBJECTS A two-group, randomized, single-blind study involving 90 undergraduate university students was conducted from January to December of 2011. INTERVENTIONS Subjects completed the State-Trait Anxiety Inventory (STAI) form Y-1 (State Anxiety, SA) and Y-2 (Trait Anxiety, TA). Then, each subject lay on a treatment table for 20 minutes. The acupuncture group had needles inserted into select acupoints; control subjects did not. Subjects then completed the STAI form Y-1 again, after which they completed the Automated Operation Span Task (AOSPAN) - a computerized test of working memory. MAIN OUTCOME MEASURES Performance on the AOSPAN and the STAI scores were the main measures of the outcomes. RESULTS The acupuncture group scored 9.5% higher than the control group on the AOSPAN Total Correct Score (65.39 vs. 59.9, p=0.0134), and committed 36% fewer math errors (2.68 vs. 4.22, p=0.0153). Acupuncture subjects also reported lower SA after intervention than control subjects (26.14 vs. 29.63, p=0.0146).

Abstract
Alzheimer's disease is the most common form of dementia diagnosed in the aging population worldwide. The cause of Alzheimer's is still not clear. There is no cure for the disease and current treatments are only symptomatic relieve. The search for new treatment is made ever more urgent due to increasing population aging. Acupuncture has been in practice in China for more than 3000 years and used to treat a wide variety of conditions including cardiovascular and psychiatric diseases, acute, and chronic pain. In this chapter, we review recent development on the effects and mechanisms of acupuncture on Alzheimer's disease. In Alzheimer's animal models, acupuncture stimulation at acupoints enhances cholinergic neurotransmission, trophic factor releasing, reduces apoptotic and oxidative damages, improves synaptic plasticity and decreases the levels of Aβ proteins in the hippocampus and relevant brain regions. The biochemical modulations by acupuncture in the brains of Alzheimer's models are correlated with the cognitive improvement. In Alzheimer's patients, functional brain images demonstrated that acupuncture increased in the activity in the temporal lobe and prefrontal lobe which are related to the memory and cognitive function. Although only a few acupuncture clinical studies with a small number of participants are reported, they represent an important step forward in the research of both acupuncture and Alzheimer's. Translation of acupuncture research in animal model studies into the human subjects will undoubtedly enhance acupuncture efficacy in clinical study and treatment which could eventually lead to a safer, well-tolerated and inexpensive form of care for Alzheimer's patients.

Abstract
RATIONALE Cocaine addiction is associated with high rates of relapse, and stress has been identified as a major risk factor. We have previously demonstrated that acupuncture reduces drug self-administration and dopamine release in the nucleus accumbens (NAc), a brain structure implicated in stress-induced reinstatement of drug-seeking behavior. OBJECTIVE This study was conducted to investigate the effects of acupuncture on footshock-induced reinstatement of cocaine-seeking and the expression of c-Fos and the transcription factor cAMP response element-binding protein (CREB) in the NAc, used as markers of neuronal activation in conditions of stress-induced reinstatement to cocaine. METHODS Male Sprague-Dawley rats were trained to self-administer cocaine (1.0 mg/kg) for 14 days, followed by extinction and then footshock stress. Acupuncture was applied at bilateral Shenmen (HT7) points for 1 min after footshock stress. RESULTS AND CONCLUSIONS Acute footshock stress reinstated cocaine-seeking behavior and enhanced c-Fos expression and phosphorylated CREB (pCREB) activation in the NAc shell in cocaine pre-exposed rats. On the other hand, acupuncture at HT7, but not at control point (LI5), markedly reduced reinstatement of cocaine-seeking (86.5 % inhibition vs. control value), c-Fos expression (81.7% inhibition), and pCREB activation (79.3% inhibition) in the NAc shell. These results suggest that acupuncture attenuates stress-induced relapse by regulating neuronal activation in the NAc shell.

Abstract
This review aims to examine the volume and quality of the evidence base which supports the use of acupuncture in the treatment of anxiety disorders. A literature review was conducted using Pubmed, Google scholar, AMED, BMJ, Embase, Psychinfo, Cochrane library, Ingenta connect, and Cinahl databases. Keywords were "anxiety,""anxious,""panic,""stress,""phobia," and "acupuncture" limited to year 2000 onwards and English language where available. The quality of research examining the use of acupuncture in the treatment of anxiety disorders is extremely variable. There is enormous variety regarding points used, number of points used in a session, duration of sessions, frequency of treatment and duration of treatment programme. While the generally poor methodological quality, combined with the wide range of outcome measures used, number and variety of points, frequency of sessions, and duration of treatment makes firm conclusions difficult. Against this, the volume of literature, consistency of statistically significant results, wide range of conditions treated and use of animal test subjects suggests very real, positive outcomes using a treatment method preferred by a population of individuals who tend to be resistant to conventional medicine.

Abstract
When an acupuncture needle is inserted into a designated point on the body and
mechanical or electrical stimulation is delivered, various neural and neuroactive
components are activated. The collection of the activated neural and neuroactive
components distributed in the skin, muscle, and connective tissues surrounding the
inserted needle is defined as a neural acupuncture unit (NAU). The traditionally defined
acupoints represent an anatomical landmark system that indicates local sites where NAUs
may contain relatively dense and concentrated neural and neuroactive components, upon
which acupuncture stimulation would elicit a more efficient therapeutic response. The
NAU-based local mechanisms of biochemical and biophysical reactions play an important
role in acupuncture-induced analgesia. Different properties of NAUs are associated with
different components of needling sensation. There exist several central pathways to
convey NAU-induced acupuncture signals, Electroacupuncture (EA) frequency-specific
neurochemical effects are related to different peripheral and central pathways transmitting
afferent signals from different frequency of NAU stimulation. More widespread and intense
neuroimaging responses of brain regions to acupuncture may be a consequence of more
efficient NAU stimulation modes. The introduction of the conception of NAU provides a
new theoretical approach to interpreting effects and mechanisms of acupuncture in
modern biomedical knowledge framework.

Acupuncture stimulation alleviates corticosterone-induced impairments of spatial memory and cholinergic neurons in rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2011; 2012:670536.

Abstract
The purpose of this study was to examine whether acupuncture improves spatial cognitive impairment induced by repeated corticosterone (CORT) administration in rats. The effect of acupuncture on the acetylcholinergic system was also investigated in the hippocampus. Male rats were subcutaneously injected with CORT (5 mg/kg) once daily for 21 days. Acupuncture stimulation was performed at the HT7 (Sinmun) acupoint for 5 min before CORT injection. HT7 acupoint is located at the end of transverse crease of ulnar wrist of forepaw. In CORT-treated rats, reduced spatial cognitive function was associated with significant increases in plasma CORT level (+36%) and hippocampal CORT level (+204%) compared with saline-treated rats. Acupuncture stimulation improved the escape latency for finding the platform in the Morris water maze. Consistently, the acupuncture significantly alleviated memory-associated decreases in cholinergic immunoreactivity and mRNA expression of BDNF and CREB in the hippocampus. These findings demonstrate that stimulation of HT7 acupoint produced significant neuroprotective activity against the neuronal impairment and memory dysfunction.

Abstract
Acupuncture therapy has been applied to various psychiatric diseases and chronic pain since acupuncture stimulation might affect brain activity. From this point of view, we investigated the effects of acupuncture on autonomic nervous system and brain hemodynamics in human subjects using ECGs, EEGs and near-infrared spectroscopy (NIRS). Our previous studies reported that changes in parasympathetic nervous activity were correlated with number of de-qi sensations during acupuncture manipulation. Furthermore, these autonomic changes were correlated with EEG spectral changes. These results are consistent with the suggestion that autonomic changes induced by needle manipulation inducing specific de-qi sensations might be mediated through the central nervous system, especially through the forebrain as shown in EEG changes, and are beneficial to relieve chronic pain by inhibiting sympathetic nervous activity. The NIRS results indicated that acupuncture stimulation with de-qi sensation significantly decreased activity in the supplementary motor complex (SMC) and dorsomedial prefrontal cortex (DMPFC). Based on these results, we review that hyperactivity in the SMC is associated with dystonia and chronic pain, and that in the DMPFC is associated with various psychiatric diseases with socio-emotional disturbances such as schizophrenia, attention deficit hyperactive disorder, etc. These findings along with the previous studies suggest that acupuncture with de-qi sensation might be effective to treat the various diseases in which hyperactivity in the SMA and DMPFC is suspected of playing a role.

Abstract
A previous study reported that the PC6 acupuncture point can alleviate chronic mild stress (CMS)-induced anxiety [17]. Following the previous study, this study examined the effects of the PC6 acupuncture point on CMS-induced memory loss. The memory storage and acetylcholinesterase (AchE) activity in the hippocampus were measured, respectively, using a passive avoidance test (PAT) and AchE immunohistochemistry. In the PAT (retention test), the CMS group showed a markedly lower latency time than the control (post (72h): P<0.01, post (96h): P<0.05, post (120h): P<0.001). However, acupuncture at PC6 significantly recovered the impairment of memory compared to the CMS group (post (120h): P<0.001). Exposure to CMS also significantly decreased the AchE activity in the hippocampus compared to the control rats. Acupuncture stimulation at the PC6 point on the pericardium channels (3min), but not at other points (TE5), produced memory improvements and an increase in AchE reactivity in the hippocampus compared to the CMS group. These results show that the acupuncture point is effective in restoring the CMS-related biochemical and behavioral impairments, such as learning and memory.

Abstract
Emergence of posttraumatic-like behaviors following chronic trauma is of interest given the rising prevalence of combat-related posttraumatic stress disorder (PTSD). Stress associated with combat usually involves chronic traumatization, composed of multiple, single episode events occurring in an unpredictable fashion. In this study, we investigated whether rats recovering from repeated trauma in the form of chronic variable stress (CVS) express posttraumatic stress-like behaviors and dysregulated neuroendocrine responses. Cohorts of Long-Evans rats underwent a 7 day CVS paradigm followed by behavioral and neuroendocrine testing during early (16 h post CVS) and delayed (7 day) recovery time points. A fear conditioning-extinction-reminder shock paradigm revealed that CVS induces exaggerated fear recall to reminder shock, suggestive of potentiated fear memory. Rats with CVS experience also expressed a delayed expression of fearful arousal under aversive context, however, social anxiety was not affected during post-CVS recovery. Persistent sensitization of the hypothalamic-pituitary-adrenocorticotropic response to a novel acute stressor was observed in CVS exposed rats. Collectively, our data are consistent with the constellation of symptoms associated with posttraumatic stress syndrome, such as re-experiencing, and arousal to fearful contexts. The CVS-recovery paradigm may be useful to simulate trauma outcomes following chronic traumatization that is often associated with repeated combat stress.
