Abstract
INTRODUCTION Protracted opioid abstinence syndrome (POAS) refers to a series of physical discomforts and neuropsychiatric symptoms after discontinuation of opioid-type substances for a certain amount of time and is one of the main causes of relapse. Studies have shown that acupuncture is effective in the treatment of POAS. We plan to conduct this systematic review and meta-analysis to assess the efficacy and safety of acupuncture for POAS. METHODS AND ANALYSIS A comprehensive search of studies will be carried out in the following databases from inception to 31 January 2023: Web of Science, Embase, PubMed, Chinese Biology Medicine, China National Knowledge Infrastructure, Wan Fang Database and Chinese Scientific Journal Database (VIP). WHO International Clinical Trials Registry Platform, ClinicalTrials.gov and Chinese Clinical Trial Registry will also be searched for ongoing relevant trials, and 'grey literatures' will be identified from GreyNet International, OpenGrey and Google Scholar. Randomised controlled trials regarding acupuncture therapy for treatment of POAS will be included. The primary outcome is the severity of protracted withdrawal symptoms. Two reviewers will screen studies using the inclusion criteria, extract data and assess the risk of bias, respectively. The quality of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluation. Data synthesis will be performed using RevMan V.5.4.1. ETHICS AND DISSEMINATION This study will not invade patients' personal privacy, and so ethical review is not required. The results will be disseminated in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42022382978.

Circular RNA expression profiling in the nucleus accumbens: Effects of electroacupuncture treatment on morphine-induced conditioned place preference. Addict Biol 2020; 25:e12794. [PMID: 31240833 DOI: 10.1111/adb.12794] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Revised: 04/16/2019] [Accepted: 05/23/2019] [Indexed: 11/30/2022]
Abstract
Electroacupuncture (EA) has been developed on the basis of traditional Chinese acupuncture. EA can suppress craving in opioid addicts and opioid-seeking responses in rodents. However, the molecular mechanism of EA on the rewarding properties of morphine and craving responses is not known. Here, we have applied a conditioned place preference paradigm in mice to measure morphine-induced rewarding effects along with EA treatment. Circular RNAs (circRNAs) can function as micro RNA (miRNA) sponges to effectively regulate gene expression levels. CircRNA profiling within the nucleus accumbens (NAc) was performed in EA-treated and sham-treated mice. Following RNAseq, data were analyzed by gene ontology (GO) and Kyoto Encyclopedia Genes and Genomes (KEGG) tools. We identified 112 significantly differentially expressed circRNAs, including 51 that were up-regulated and 61 that were down-regulated. Our bioinformatics analyses show that these differentially expressed circRNAs map into pathways that are mainly involved with renin secretion and the cGMP-PKG signaling. We further constructed a circRNA-miRNA network that predicts the potential roles of the differentially expressed circRNAs and the interaction of circRNAs with miRNAs. Our secondary sequencing and bioinformatics analysis in the NAc after EA treatment on morphine-induced CPP provides putative novel targets on molecular mechanisms involved in morphine reinforcement and possibly craving.

Abstract
Opiate addiction has a high rate of relapse. The accumulating evidence shows that electroacupuncture (EA) may be effective for the treatment of opiate relapse. However, the change of expression of CB1-Rs and CB2-Rs involve in 2Hz EA anti-relapse pathway is still unclear. To explore the changes of expression of CB1-Rs and CB2-Rs, heroin self-administration (SA) model rats were adopted and treated using 2Hz EA. The expressions of CB1-Rs and CB2-Rs were observed using immunohistochemistry method. The results showed that, compared with the control group, active pokes in the heroin-addicted group increased, while the active pokes decreased significantly in 2Hz EA group compared with heroin-addicted group. Correspondingly, the expression of CB1-Rs in prefrontal cortex (PFC), hippocampus (Hip), nucleus accumbens (NAc) and ventral tegmental area (VTA) all increased significantly while the expression of CB2-Rs in those relapse-relevant brain regions decreased obviously in heroin-addicted group when compared with the control group. In addition, the expression of CB1-Rs obviously decreased in the 2Hz EA group while the expression of CB2-Rs in those relapse-relevant brain regions increased significantly when compared with the heroin-addicted group. It indicated that 2Hz EA could attenuate the heroin-evoked seeking behaviors effectively. The anti-relapse effects of 2Hz EA might be related to the decrease of CB1-Rs and increase of CB2-Rs expression in relapse-relevant brain regions of heroin SA rats.

Abstract
High compliance with methadone maintenance therapy (MMT) is crucial to successful opioid abstinence in addicts. However, MMT has numerous side effects, including reductions in quality of life and quality of sleep. Many studies have demonstrated that electroacupuncture relieves withdrawal symptoms in opioid addicts. The present study was a case-control study. From January 2015 to September 2016, 106 patients undergoing MMT at a medical center in central Taiwan were recruited and separated into an electroacupuncture treatment group and a control group. Electroacupuncture was performed for 15 minutes twice weekly for 4 weeks. The electroacupuncture treatment group was discovered to have improved quality of life, especially in terms of vitality and mental health. Although electroacupuncture did not significantly improve sleep quality, we found that sleep quality was significantly improved once methadone dosage had been reduced. Electroacupuncture can improve quality of life in patients undergoing MMT. If methadone dosage can be reduced and electroacupuncture can be employed, both sleep and life quality can be improved.

Abstract
The United States (U.S.) is facing a national opioid epidemic, and medical systems are in need of non-pharmacologic strategies that can be employed to decrease the public's opioid dependence. Acupuncture has emerged as a powerful, evidence-based, safe, cost-effective, and available treatment modality suitable to meeting this need. Acupuncture has been shown to be effective for the management of numerous types of pain conditions, and mechanisms of action for acupuncture have been described and are understandable from biomedical, physiologic perspectives. Further, acupuncture's cost-effectiveness can dramatically decrease health care expenditures, both from the standpoint of treating acute pain and through avoiding addiction to opioids that requires costly care, destroys quality of life, and can lead to fatal overdose. Numerous federal regulatory agencies have advised or mandated that healthcare systems and providers offer non-pharmacologic treatment options for pain. Acupuncture stands out as the most evidence-based, immediately available choice to fulfil these calls. Acupuncture can safely, easily, and cost-effectively be incorporated into hospital settings as diverse as the emergency department, labor and delivery suites, and neonatal intensive care units to treat a variety of commonly seen pain conditions. Acupuncture is already being successfully and meaningfully utilized by the Veterans Administration and various branches of the U.S. Military, in some studies demonstrably decreasing the volume of opioids prescribed when included in care.

Abstract
Addressing the global obesity epidemic requires innovative approaches that are also acceptable to affected individuals. There is growing evidence suggesting that food addiction, one contributor to obesity, bears many similarities to drug and alcohol addiction, presenting a potential role for addiction-focused acupuncture as a novel treatment modality. In this perspective article, we begin by briefly reviewing the evidence linking food and drug/alcohol addiction. We then describe the development of an acupuncture-based protocol for treating opioid addiction in Hong Kong in the 1970s and discuss the evidence base for acupuncture's efficacy in treating a range of substance use disorders. Next, we describe acupuncture's proposed mechanism of action in attenuating withdrawal and promoting abstinence. Finally, we note the dearth of studies specifically examining the effectiveness of acupuncture in treating food addiction and suggest that more research should focus in this area as part of the effort to combat rising rates of obesity worldwide.

Abstract
There is an emerging consensus that between one fifth and one half of breast cancer patients experience chemotherapy-associated cognitive dysfunction. Research shows that patients with cancer are often interested in acupuncture for symptom relief. A clinical question thus arises: What should physicians advise their patients regarding the use of acupuncture to alleviate or ameliorate chemotherapy-associated cognitive dysfunction? The authors review and synthesize 2 bodies of relevant research literature: (1) the developing literature on the etiology and nature of chemotherapy-associated cognitive dysfunction and (2) the literature concerning acupuncture for neurological diseases and psychological issues. There is evidence that acupuncture may be effectively used to manage a range of psychoneurological issues, some of which are similar to those experienced by patients with chemotherapy-associated cognitive dysfunction. The evidence of efficacy is more promising for psychological than neurological conditions. Given evidence of possible efficacy combined with evidence of demonstrated safety, we suggest that physicians should support patient decisions to use acupuncture services for chemotherapy-associated cognitive dysfunction, especially given the lack of proven alternatives.

Abstract
OBJECTIVE To assess the therapeutic effect of transcutaneous electric acupoint stimulation (TEAS) for the treatment of withdrawal syndrome in heroin addicts. METHODS A total of 63 male heroin addicts with withdrawal score higher than 20 were recruited in the Detoxification Center of Zhongshan city, Guangdong province, China. They were randomly distributed into two groups: TEAS group (n = 31) received TEAS by using a Han's acupoint nerve stimulator (HANS) model 200A with two output channels, 2-3 sessions per day, 30 minutes per session for 10 consecutive days. Electrical stimulation of alternating frequencies of 2- and 100-Hz with 3 second each, and with intensity of 10-15 mA was applied on Hegu (LI-4) and Laogong (PC-8) points on one hand, and Neiguan (PC-6) and Waiguan (SJ-5) points on the other forearm via electroconductive skin pads of 4 cm × 4 cm in size. The control group (n = 32) was treated with similar procedure except that the leads of the output of the stimulator was disconnected. Assessments of the severity of the withdrawal syndrome were conducted one day before and on each day during the whole treatment period of 10 days. Buprenorphin of 1 mg per day sublingually was provided to all subjects in the first two days, and then to those with withdrawal score over 20 in the following days. RESULTS The TEAS treatment dramatically alleviated the withdrawal syndrome during heroin detoxification. No significant difference was found in withdrawal scores between the two groups at the beginning of the observation. Withdrawal scores showed a more marked drop in TEAS group than the control starting from the second day, and maintained at a lower level for the whole course of treatment. The area under the curve of withdrawal score in TEAS group was only 40% of that in the control (P < 0.001, two way repeated measures analysis of variance), and the requirement of buprenorphine was only 10% of that in the control. No adverse effects were observed in either group. CONCLUSION TEAS of 2/100 Hz for 10 days in abrupt abstinence of the heroin addicts resulted in a marked reduction of the withdrawal syndrome as well as a reduced requirement for rescue opioids.

Abstract
Electroacupuncture (EA) at ST36 is effective for improving gastric motility. However, the underlying mechanism remains poorly understood. The aim of this study was to investigate the effects of EA on gastric contraction and to determine whether interstitial cells of Cajal (ICCs) are involved. Rats were randomized into control, diabetic (DM), diabetic with sham EA (DM + SEA), diabetic with low frequency EA (DM + LEA) and diabetic with high frequency EA (DM + HEA) groups. EA was performed everyday for four and eight weeks. Contractions in antrum strips were explored using the organ bath technique. Western blotting was employed to determine c-kit and transmembrane stem cell factor (M-SCF) expression in the gastric antrum, and levels of soluble stem cell factor (S-SCF) in serum were determined by enzyme-linked immunosorbent assay (ELISA). The distribution of ICCs was further assessed by immunohistochemistry. The results were as follows: (1) Contractions in the DM group were attenuated at four and eight weeks, but LEA and HEA restored the attenuated contraction. (2) ICCs were significantly decreased at eight weeks without alteration at four weeks in DM group, but were rescued in the LEA and HEA groups. (3) Whereas M-SCF and S-SCF in the DM group were slightly decreased at four weeks and were dramatically reduced at eight weeks, LEA and HEA markedly enhanced SCF at eight weeks. Collectively, the data suggest that in diabetic rats, LEA and HEA at ST36 could facilitate contraction of the gastric antrum, possibly by involving the SCF/c-kit pathway.

Abstract
In order to investigate the influence of electroacupuncture on heroin seeking behavior and the expression of CB2-Rs in the relapse-relevant brain regions, heroin self-administration rat model which represents the heroin relapse behaviors was developed with progressive fixed ratio program. The model rats were randomly divided into 3 groups: control group, heroin-addicted group and 2Hz electroacupuncture group (stimulating on acupoints zusanli and sanyinjiao). The expression of CB2-Rs in the relapse-relevant brain regions were assessed with immunohistochemistry technologies. The reinstatement of heroin seeking behavior induced by conditioned cue priming showed that compared with the heroin-addicted group, active pokes in the 2Hz electroacupuncture group decreased significantly (p<0.05). Compared with the control group, the expression of CB2-Rs in prefrontal cortex (PFC) and nucleus accumbens (NAc) was significantly decreased (p<0.05) in heroin-addicted group and increaseed significantly recover (p<0.05) in the 2Hz electroacupuncture group. Our present results showed that 2Hz-electroacupuncture could attenuate the conditioned cue-evoked heroin-seeking behavior and the inhibitory effect was mediated partially by the increase CB2-Rs expression in relapse-relevant brain regions in heroin-addicted rats.

Abstract
Functional brain network, one of the main methods for brain functional studies, can provide the connectivity information among brain regions. In this research, EEG-based functional brain network is built and analyzed through a new wavelet limited penetrable visibility graph (WLPVG) approach. This approach first decompose EEG into δ, θ, α, β sub-bands, then extracting nonlinear features from single channel signal, in addition forming a functional brain network for each sub-band. Manual acupuncture (MA) as a stimulation to the human nerve system, may evoke varied modulating effects in brain activities. To investigating whether and how this happens, WLPVG approach is used to analyze the EEGs of 15 healthy subjects with MA at acupoint ST36 on the right leg. It is found that MA can influence the complexity of EEG sub-bands in different ways and lead the functional brain networks to obtain higher efficiency and stronger small-world property compared with pre-acupuncture control state.

Abstract
Scant scientific evidence supports the efficacy of acupuncture in the treatment of opiate dependence. The purpose of this study was to examine the effectiveness of acupuncture for heroin addicts on methadone maintenance by measuring the daily consumption of methadone, variations in the 36-item Short Form Health Survey-36 (SF-36) and Pittsburgh Sleep Quality Index (PSQI) scores, and heroin craving. Sixty heroin addicts were randomly assigned to true acupuncture (electroacupuncture at the Hegu [LI4] and Zusanli [ST36] acupoints, as well as acupuncture at the Ear Shenmen) or sham acupuncture (minimal acupuncture at the Hegu and Zusanli acupoints without electrical stimulation and superficial acupuncture at the Ear Shenmen), twice weekly for 4 weeks. From week 2 onwards, the daily dose of methadone was reduced by a significantly greater amount with true acupuncture compared with sham acupuncture. True acupuncture was also associated with a greater improvement in sleep latency at follow-up. All adverse events were mild in severity. Acupuncture appears to be a useful adjunct to methadone maintenance therapy (MMT) in heroin addiction.

Mechanisms of electroacupuncture-induced analgesia on neuropathic pain in animal model. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:436913. [PMID: 23983779 PMCID: PMC3747484 DOI: 10.1155/2013/436913] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/20/2013] [Revised: 06/23/2013] [Accepted: 07/11/2013] [Indexed: 01/28/2023]
Abstract
Neuropathic pain remains as one of the most difficult clinical pain syndromes to treat. Electroacupuncture (EA), involving endogenous opioids and neurotransmitters in the central nervous system (CNS), is reported to be clinically efficacious in various fields of pain. Although multiple experimental articles were conducted to assess the effect of EA-induced analgesia, no review has been published to assess the efficacy and clarify the mechanism of EA on neuropathic pain. To this aim, this study was firstly designed to evaluate the EA-induced analgesic effect on neuropathic pain and secondly to guide and help future efforts to advance the neuropathic pain treatment. For this purpose, articles referring to the analgesic effect of acupuncture on neuropathic pain and particularly the work performed in our own laboratory were analyzed. Based on the articles reviewed, the role of spinal opioidergic, adrenergic, serotonergic, cholinergic, and GABAergic receptors in the mechanism of EA-induced analgesia was studied. The results of this research demonstrate that μ and δ opioid receptors, α2-adrenoreceptors, 5-HT1A and 5-HT3 serotonergic receptors, M1 muscarinic receptors, and GABAA and GABAB GABAergic receptors are involved in the mechanisms of EA-induced analgesia on neuropathic pain.

Abstract
Morphine causes physical and psychological dependence for individuals after repeated-use. Above all, our previous study showed that acupuncture attenuated reinstatement of morphine-seeking behavior induced by pharmacological cue. In this study, we investigated whether acupuncture could suppress the reinstatement of morphine-seeking behavior induced by the combination of environmental and pharmacological cues and the possible neuronal involvement. Male Sprague-Dawley rats were trained to self-administer morphine (1.0 mg/kg) for 3 weeks. Following the withdrawal phase (7 days), the effects of acupuncture on reinstatement of morphine-seeking behavior were investigated. For the investigation of neuronal involvement, the GABAA receptor antagonist bicuculline and the GABAB receptor antagonist SCH 50911 were pre-treated. Morphine-seeking behavior induced by combination of re-exposure to the operant chamber and morphine injection was suppressed perfectly by acupuncture at SI5, but not at the control acupoint LI5 and this effect was blocked by pre-treatment with the GABA receptor antagonists. This study suggests that acupuncture at SI5 can be considered as a predominant therapy for the reinstatement of morphine-seeking behavior in humans.

Electroacupuncture reduces cocaine-induced seizures and mortality in mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:134610.

Abstract
The aims of this study were to characterize the protective profile of electroacupuncture (EA) on cocaine-induced seizures and mortality in mice. Mice were treated with EA (2 Hz, 50 Hz, and 100 Hz), or they underwent needle insertion without anesthesia at the Dazhui (GV14) and Baihui (GV20) acupoints before cocaine administration. EA at 50 Hz applied to GV14 and GV20 significantly reduced the seizure severity induced by a single dose of cocaine (75 mg/kg; i.p.). Furthermore, needle insertion into GV14 and GV20 and EA at 2 Hz and 50 Hz at both acupoints significantly reduced the mortality rate induced by a single lethal dose of cocaine (125 mg/kg; i.p.). In the sham control group, EA at 50 Hz applied to bilateral Tianzong (SI11) acupoints had no protective effects against cocaine. In addition, EA at 50 Hz applied to GV14 and GV20 failed to reduce the incidence of seizures and mortality induced by the local anesthetic procaine. In an immunohistochemistry study, EA (50 Hz) pretreatment at GV14 and GV20 decreased cocaine (75 mg/kg; i.p.)-induced c-Fos expression in the paraventricular thalamus. While the dopamine D3 receptor antagonist, SB-277011-A (30 mg/kg; s.c), did not by itself affect cocaine-induced seizure severity, it prevented the effects of EA on cocaine-induced seizures. These results suggest that EA alleviates cocaine-induced seizures and mortality and that the dopamine D3 receptor is involved, at least in part, in the anticonvulsant effects of EA in mice.

Abstract
Augmentation of extinction with learning enhancing therapy may offer an effective strategy to combat heroin relapse. Our lab previously found that electroacupuncture (EA) not only significantly reduced cue-induced reinstatement of heroin seeking but also exhibited a promoting effect on the ability of learning and memory. In the present study, we further investigated the effects of EA on the extinction of heroin-seeking behavior in rats with a history of intravenous heroin self-administration. We trained Sprague-Dawley rats to nose-poke for i.v. heroin either daily for 4h or 25 infusions for 14 consecutive days; then the rats underwent 7 daily 3h extinction sessions in the operant chamber. To assess EA's effects on the extinction response of heroin-associated cues, 2Hz EA was administered 1h before each of the 7 extinction sessions. We also applied immunohistochemistry to detect FosB-positive nuclei in the nucleus accumbens core. We found that EA treatment facilitated the extinction response of heroin seeking but did not alter the locomotor activity in an open field testing environment. EA stimulation attenuated the FosB expression in the core of the nucleus accumbens, a brain region involved in the learning and execution of motor responses. Altogether, these results suggest that EA may provide a novel nonpharmacological approach to enhance extinction learning when combined with extinction therapy for the treatment of heroin addiction.

Abstract
New therapies are needed for alcohol abuse, a major public health problem in the U.S. and worldwide. There are only three FDA-approved drugs for treatment of alcohol abuse (naltrexone, acamprosate and disulfuram). On average these drugs yield only moderate success in reducing long-term alcohol consumption. Electroacupuncture has been shown to alleviate various drugs of abuse, including alcohol. Although previous studies have shown that electroacupuncture reduced alcohol consumption, the underlying mechanisms have not been fully elucidated. ΔFosB and FosB are members of the Fos family of transcription factors implicated in neural plasticity in drug addiction; a connection between electroacupuncture's treatment of alcohol abuse and the Fos family has not been established. In this study, we trained rats to drink large quantities of ethanol in a modified intermittent access two-bottle choice drinking procedure. When rats achieved a stable baseline of ethanol consumption, electroacupuncture (100 Hz or 2 Hz, 30 min each day) was administered at Zusanli (ST36) for 6 consecutive days. The level of FosB/ΔFosB in reward-related brain regions was assessed by immunohistochemistry. We found that the intake of and preference for ethanol in rats under 100 Hz, but not 2 Hz electroacupuncture regiment were sharply reduced. The reduction was maintained for at least 72 hours after the termination of electroacupuncture treatment. Conversely, 100 Hz electroacupuncture did not alter the intake of and preference for the natural rewarding agent sucrose. Additionally, FosB/ΔFosB levels in the prefrontal cortex, striatal region and the posterior region of ventral tegmental area were increased following excessive ethanol consumption, but were reduced after six-day 100 Hz electroacupuncture. Thus, this study demonstrates that six-day 100 Hz electroacupuncture treatment effectively reduces ethanol consumption and preference in rats that chronically drink excessive amount of ethanol. This effect of electroacupuncture may be mediated by down-regulation of FosB/ΔFosB in reward-related brain regions.

Abstract
Acupuncture as a therapeutic intervention is widely practiced in the treatment of many functional disorders including alcohol abuse. In the present study, the effects of acupuncture on alcohol withdrawal syndrome (AWS) and Fos-like immunoreactivity (FLI) in the striatum and the nucleus accumbens (NAC) of rats were investigated. During 3 days of cessation following chronic administration of ethanol (3 g/kg, i.p. for 3 weeks), rats showed a significant increase in AWS, such as hypermotility, tail rigidity, grooming and tremor, and an increase in FLI in the dopamine terminal areas of the brain. Treatment with acupuncture at zusanli (ST36) or sanyinjiao (SP6) during the withdrawal period inhibited both AWS and FLI of rats undergoing ethanol injection. These results suggest that acupuncture may be useful in the treatment of alcoholism by modulating post-synaptic neural activation in the striatum and NAC.

Abstract
Although an acupuncture needle penetrates the skin, subcutaneous tissue, and underlying muscle, the most effective locus for the somatic acupoint on the needle path is not well established. We therefore investigated the sensory innervations of tissues in the needle path of the canine Shen-Shu point and evaluated their roles in initiating an acupunctural signal. Horseradish peroxidase solution was injected at all three levels within the acupoint. Only a few peroxidase-positive neurons were observed in the L1 dorsal root ganglion following intradermal injection. Following subcutaneous injection, peroxidase-labeled neurons were detected extending from spinal levels T10 to L2, with maximal labeling at T12 (46.3%). Approximately 95% of positive neurons were at spinal levels T11, T12, T13, and L1. As a result of an intramuscular injection, labeled neurons were observed at spinal levels T12 to L3, with most labeling occurring at L1 (39.9%). Approximately 95% of positive neurons were at spinal levels T13, L1, and L2. The results suggest that most afferent terminals are in the subcutaneous tissue rather than the muscular tissue, with an approximate ratio of 3.75:1. The data provide solid evidence that sensory innervation to a somatic acupoint is confined to a spinal segment and spatially organized, and we speculate that to cause a maximum effect, the centripetally transmitted signal from needling a somatic acupoint is spatio-segmental and divergently amplified.

Abstract
Acupuncture is an accepted treatment worldwide for various clinical conditions, and the effects of acupuncture on opiate addiction have been investigated in many clinical trials. The present review systematically analyzed data from randomized clinical trials published in Chinese and English since 1970. We found that the majority agreed on the efficacy of acupuncture as a strategy for the treatment of opiate addiction. However, some of the methods in several included trials have been criticized for their poor quality. This review summarizes the quality of the study design, the types of acupuncture applied, the commonly selected acupoints or sites of the body, the effectiveness of the treatment, and the possible mechanism underlying the effectiveness of acupuncture in these trials.

Abstract
Drug addiction is a chronic brain disorder characterized by withdrawal symptoms that occur during drug abstinence and a high tendency of relapse. Compared with the currently available pharmacological interventions, acupuncture therapy has the potential to help drug addicts stay away from drugs without major adverse side effects. It has taken decades of research to optimize the parameters of electrical acupoint stimulation for detoxification and for relapse prevention, as well as to establish a safe and easy procedure by which drug addicts can use it on themselves. The discovery that acupuncture can trigger the release of opioid substances from the brain in the 1970s provided the inspiration. Following this, basic research on animals made it possible to understand the mechanisms of action and establish the procedure for treating drug addictions. This article reviews the past, present, and foreseeable future regarding the use of acupuncture-related technique for the treatment of opiate addiction from the perspective of translational medicine.

Abstract
In a previous paper we reported that electroacupuncture (EA) could suppress opioid withdrawal syndrome and increase the appetite, sleep, and body weight in heroin addicts or morphine dependent animals. Considering that opioids were known to inhibit immune function, the present study was designed to observe whether EA could modulate the immune status of morphine dependent and withdrawal mice. We found that chronic morphine-induced decrease of splenic T lymphocyte proliferation and IL-2 production can be significantly raised by 2 Hz EA, and the fluctuation of CD4+/CD8+ ratio was also run to the baseline level by the EA. These findings indicated that chronic morphine exposure-induced immune dysfunction in mice could be normalized by 2 Hz EA.

Abstract
Sleep disturbance is considered as an important symptom of acute and protracted opiate withdrawal. Current results suggest that sleep disturbance may be taken as a predictor of relapse. Appropriate sleep enhancement therapy will be in favor of the retention in treatment for opiate addicts. Our previous studies have shown that electroacupuncture (EA) is effective in suppressing morphine withdrawal syndrome. The aim of the present study is to investigate the effect of 2 and 100 Hz EA on the sleep disturbance during morphine withdrawal. Rats were made dependent on morphine by repeated morphine injections (escalating doses of 5-80 mg kg(-1), subcutaneously, twice a day) for 5 days. EA of 2 or 100 Hz was given twice a day for 3 days, starting at 48 h after the last morphine injection. Electroencephalogram and electromyogram were monitored at the end of the first and the last EA treatments, respectively. Results showed that non-rapid eye movement (NREM) sleep, REM sleep and total sleep time decreased dramatically, while the sleep latency prolonged significantly during acute morphine withdrawal. Both 2 and 100 Hz EA produced a significant increase in NREM sleep, REM sleep and total sleep time. It was suggested that EA could be a potential treatment for sleep disturbance during morphine withdrawal.

Abstract
Alleviating opiate withdrawal syndrome in addicts is a critical precondition to break away from drug and further to prevent reuse. Electroacupuncture (EA) was claimed to be effective for alleviating withdrawal syndrome, but the optimal protocol remained unclear. In the present study we found that (1) 100 Hz EA administered 12-24h after the last morphine injection suppressed the withdrawal syndrome in rats, multiple sessions of EA were more effective than single session, with the after-effect lasting for at least 7 days. (2) A down-regulation of preprodynorphin (PPD) mRNA level was observed in spinal cord, PAG and hypothalamus 60 h after the last morphine injection, which could be reversed by multiple sessions, but not a single session of EA. (3) Accompanied with the decrease of PPD mRNA level, there was an up-regulation of p-CREB in the three CNS regions, which was abolished by 100 Hz EA treatment. The findings suggest that down-regulation of p-CREB and acceleration of dynorphin synthesis in spinal cord, PAG and hypothalamus may be implicated in the cumulative effect of multiple 100Hz EA treatment for opioid detoxification.

Abstract
Electroacupuncture stimulation (EAS) has been demonstrated effective for pain relief and treating other various diseases. However, the conventional way of EAS, the bi-acupoint method, is not suitable for basis study of acupoint specificity. Moreover, its operations are inconvenient and difficult to be persevered, especially for long-term, continuous and even imperative treatments. These disadvantages motivate designs of new EAS methods. We present a novel uni-acupoint electrical stimulation method, which is applied at a single acupoint and quite meets the needs of basis study and simpler clinical application. Its pain relief effect has been evaluated by animal tests of Wistar rats. During the experiments, rats were given 30 min 2/100 Hz uni- and bi-acupoint EAS and their nociceptive thresholds before and after EAS were attained by hot-plate test. The analgesic effect was defined as the change of nociceptive threshold and used to evaluate the effectiveness of uni-acupoint EAS for pain relief. The hot-plate test results indicated that analgesic effect of uni-acupoint group was significantly higher than that of the control group and there was no significant difference of analgesic effects between uni- and bi-acupoint EAS. The results suggested that uni-acupoint method was an effective EAS method and had comparable pain relief effect with bi-acupoint method.

Abstract
Acupuncture has been used to treat drug addiction by nicotine, alcohol, cocaine and morphine. This study was designed to investigate the effect of bee venom (BV) acupuncture on hyperactivity and hyperthermia induced by acute exposure to methamphetamine (METH, 1mg/kg, s.c.) in mice. Diluted BV (20μl of 0.01, 0.1, 1 and 10mg/ml in saline, s.c.) was administered bilaterally into the Zusanli acupoint (ST36) or control points (SP9 or GB39 or tail base). BV injection into ST36 dose dependently reduced METH-induced hyperactivity and hyperthermia, while BV injection (1mg/ml) into control points did not produce these suppressive effects. METH injection significantly increased Fos expression in several brain regions including nucleus accumbens (NA), caudate putamen (CPU), ventral tegmental area (VTA), substantia nigra (SN) and locus coeruleus (LC). Interestingly, BV (1mg/ml) injection into ST36 further increased METH-induced Fos expression in NA (core and shell), SN and LC. When we performed sciatic denervation or combination treatment of BV and lidocaine (BV diluted in 5% lidocaine solution), the enhancement of Fos elevation by BV was completely blocked in the NA, SN and LC in METH-injected mice, indicating that BV-induced peripheral nerve stimulation played an important role in the BV effect. Furthermore, the effects of BV were completely blocked by the α₂-adrenoceptor antagonist, idazoxan (3mg/kg, i.p.), but not by β-adrenoceptor antagonist, propranolol (10mg/kg, i.p.). Taken together, these findings suggest that BV acupuncture into ST36 may modulate METH-induced hyperactivity, hyperthermia and Fos expression through activation of the peripheral nerve and the central α₂-adrenergic activation.

Abstract
Clinical trials are currently underway to determine the effectiveness of acupuncture in the treatment of drug addiction. While there are still many unanswered questions about the basic mechanisms of acupuncture, some evidence exists to suggest that acupuncture can play an important role in reducing reinforcing effects of abused drugs. The purpose of this article is to critically review these data. The neurochemical and behavioral evidence showed that acupuncture's role in suppressing the reinforcing effects of abused drugs takes place by modulating mesolimbic dopamine neurons. Also, several brain neurotransmitter systems such as serotonin, opioid and amino acids including GABA have been implicated in the modulation of dopamine release by acupuncture. These results provided clear evidence for the biological effects of acupuncture that ultimately may help us to understand how acupuncture can be used to treat abused drugs. Additional research using animal models is of primary importance to understanding the basic mechanism underlying acupuncture's effectiveness in the treatment of drug addiction.

Abstract
UNLABELLED Our previous fMRI and microdialysis measurements showed that electroacupuncture (EA) at LI4 was effective in alleviating excessive cerebral dopamine release induced by d-amphetamine (AMPH) in rats. We now compare the effect of EA in adjusting excess dopamine release at two stimulating frequencies (2 Hz versus 100 Hz at LI4) and at two acupoints (forepaw (LI4) versus hindpaw (ST36), at 2 Hz). fMRI measurements of relative cerebral blood volume (rCBV) were used to monitor the brain activity of "rest", followed by AMPH challenge, 10 min "rest", and then 20 min of EA. RESULTS EA at LI4 and ST36 significantly attenuated the AMPH-induced rCBV increases in the striatum, S1 cortex, and thalamus. Frequency: EA at 100 Hz induced greater attenuation of rCBV than EA at 2 Hz in the S1, insula, anterior cingulate cortices, dorsolateral striatum, and thalamus. Acupoints: EA at LI4 modulated a broader area in the medial anterior striatum while EA at ST36 modulated a more site-specific area in the dorsolateral striatum. In the thalamus, EA at LI4 showed greater attenuating effect than EA at ST36 did. However, in the insular cortex, EA at ST36 showed stronger attenuation. CONCLUSION EA at both LI4 and ST36 was effective in restoring dopamine homeostasis from an excess state, with the most effective response at LI4 with 100 Hz, while the responses to 2Hz EA at LI4 and ST36 showed slightly different spatial distribution of MR signal. This therefore provided insight into the neurophysiological basis of electroacupuncture effects in cortical and subcortical circuits.

Abstract
Over the last three decades there has been an increasing interest in acupuncture treatment of substance abuse around the world. Three important steps can be identified in this field. Dr. Wen of Hong Kong was the first (1972) to report that acupuncture at 4 body points and 2 ear points combined with electrical stimulation can relieve opioid withdrawal signs in the addicts. The second major step was made by Dr. M. Smith in New York, the head of the National Acupuncture Detoxification Association (NADA) of the USA, who finalized a protocol (1985), using only ear points without electrical stimulation for the treatment of drug abuse. The recent advance in this field was made by Dr. Han of the Peking University, Beijing, who characterized a protocol (2005), using electrical stimulation of identified frequencies on body points to ameliorate heroin withdrawal signs and prevent relapse of heroin use. In this review, the efficacy of acupuncture and related techniques for the treatment of drug dependence in experimental settings and clinical practice will be reviewed, and the possible mechanisms underlying this effect be discussed.

Abstract
The aim of this study was to observe the effect of electroacupuncture (EA) on chronic morphine-induced neuronal morphological changes in the ventral tegmental area (VTA) in rats at electron-microscopic level. Fourteen days of administering escalating doses of morphine induced pathological morphological changes of neurons in the VTA: the rough endoplasmic reticulum swelled, membrane configuration of the nucleus and mitochondria blurred, and structure of myelin sheath changed. Both 2 and 100 Hz EA treatment reversed the morphological alterations induced by chronic morphine administration. The findings provide new evidence that EA may serve as a potential therapy in treating opiate addiction.

Abstract
Chronic morphine administration induces functional and morphological alterations in the mesolimbic dopamine system (MLDS), which is believed to be the neurobiological substrate of opiate addiction. Our previous studies have demonstrated that peripheral electrical stimulation (PES) can suppress morphine withdrawal syndrome and morphine-induced conditioned place preference (CPP) in rats. The present study was designed to investigate if PES could reverse the cell size reduction induced by chronic morphine treatment in the ventral tegmental area (VTA), which is an important area of the MLDS. Immunohistochemical observations showed that the cell size of dopaminergic neurons in the VTA reduced significantly in the chronic morphine-treated rats with a concomitant decrease in the number of BDNF-positive cells compared to the saline-treated rats. A much milder morphological change, accompanying with an increased number of BDNF-positive cells, was observed in dopaminergic neurons in the rats that received repeated 100 Hz PES after morphine withdrawal. In another experiment, enzyme-linked immunosorbent assay (ELISA) reconfirmed a significant up-regulation of BDNF protein level in the VTA in the rats received 100 Hz PES after morphine abstinence. These results indicate that PES could facilitate the morphological recovery of the VTA dopaminergic cells damaged by chronic morphine treatment and up-regulate the BDNF protein level in the VTA. Activation of endogenous BDNF by PES may play a role in the recovery of the injured dopaminergic neurons in the morphine addictive rats.

Abstract
Acupuncture stimulation elicited a composite of sensations termed deqi that is related to clinical efficacy. Neurobiological studies have identified the hypothalamus as an important component in mediating the deqi. Functional changes in hypothalamus persist after abstinence in addicts. We investigated the activation in the hypothalamus associated with acupuncture stimulation in healthy volunteers and heroin addicts by fMRI. Cortisol level and psychophysical responses, including the deqi sensation (an acupuncture effect of needle-manipulation), anxiety, and sharp pain, were also assessed. The activation of the hypothalamus was more robust in the addicts than that in the healthy subjects during acupuncture stimulation. The deqi scores of the heroin addicts were significantly higher than those of the healthy subjects during acupuncture treatment. An acupuncture sensation scale predicted the activation of the hypothalamus associated with the deqi sensation.

Abstract
Many studies have shown that acupuncture can contribute to the biochemical balance in the central nervous system and maintenance or recovery of homeostasis. It is well known that chronic administration of ethanol may produce depletion or sensitization of extracellular dopamine levels in the nucleus accumbens. The present study was designed to investigate the effects of acupuncture on chronic ethanol-induced changes in extracellular dopamine levels in the nucleus accumbens shell (using in vivo microdialysis in unanesthetized rats). Male Sprague-Dawley rats were treated with 3 g/kg/day of ethanol (20%, w/v) or saline by intraperitoneal injection for 21 days. Following 72 h of ethanol withdrawal, acupuncture was applied at bilateral Shenmen (HT7) points for 1 min. Different group of rats using the same paradigm of ethanol treatment were acupunctured at the same points after the systemic ethanol challenge (3 g/kg, i.p.). Acupuncture at the specific acupoint HT7, but not at control points (PC6 or tail) significantly prevented both a decrease of extracellular dopamine levels in the nucleus accumbens during ethanol withdrawal and an increase in accumbal dopamine levels induced by the ethanol challenge. These results provided strong evidence that stimulation of the specific acupoint HT7 helps to normalize the release of dopamine in the mesolimbic system following chronic ethanol treatment.

Abstract
Spasticity in rat hindlimbs was induced by compressing cervical spinal cord with a wax ball. Ashworth score and H-reflex were measured 1 week after the surgery. The results showed that: (1) muscle spasm was detected in the hindlimbs a week after the operation and maintained at least 8 weeks, (2) in the spastic animals, dynorphin A (1-17)-ir decreased significantly in thoracic and lumbar segments of the spinal cord and (3) peripheral administration of kappa receptor agonist U50488H and electrical stimulation at 100 Hz effectively relieved the muscle spasm. Our data supported the note that the reduction of endogenous dynorphin A (1-17) might play an important role in the pathogenesis of spinally induced muscle spasticity and the replenishment of its shortage might relieve the spasticity.

Abstract
Acupuncture as a therapeutic intervention has been used for the treatment of many functional disorders including substance abuse. However, there are still many unanswered question about the basic mechanism underlying acupuncture's effectiveness in the treatment of drug addiction. Repeated injection of psycostimulants or morphine can produce behavioral and neurochemical sensitization and have been used as a model for studying drug addiction. The present study was designed to investigate the effect of acupuncture on repeated morphine-induced changes in extracellular dopamine levels using in vivo microdialysis and repeated morphine-induced behavioral changes. Male Sprague-Dawley rats were treated with saline or increasing doses of morphine (10, 20 and 40 mg/kg, s.c., twice daily for 3 days). Following 15 days of withdrawal, acupuncture was applied at bilateral Shenmen (HT7) points for 1 min after the systemic challenge with morphine HCl (5 mg/kg, s.c.). Results showed that acupuncture at the specific acupoint HT7, but not at control points (TE8 and tail) significantly decreased both dopamine release in the nucleus accumbens and behavioral hyperactivity induced by a systemic morphine challenge. These results suggest that the therapeutic effect of acupuncture on morphine addiction occurs through inhibition of neurochemical and behavioral sensitization to morphine.

Abstract
Our previous studies have shown that 2 Hz peripheral electrical stimulation (PES) can suppress morphine-induced conditioned place preference (CPP) in the rat, although the mechanisms remain unclear. Since CPP involves the mechanism of learning and memory, it is rational to ask whether the suppressive effect of repeated 2 Hz PES on morphine-induced CPP is due to an impairment of the function of spatial learning and memory. Rats were trained with 4 mg/kg morphine, i.p. for 4 days to establish the CPP. Twenty-four hours after the CPP testing, they were given PES at 2 Hz once a day for 1, 3 or 5 days, followed by another CPP testing. The results showed that (1) the morphine-induced CPP was significantly inhibited by 3 or 5 consecutive sessions, but not by single session of 2 Hz PES. (2) A test of spatial leaning and memory ability using the Morris water maze task revealed that 2 Hz PES per se exhibited a promoting, rather than a deteriorating effect on the ability of spatial memory. (3) 2 Hz PES by itself produced a moderate yet significant CPP. The results imply that (a) a low frequency PES can produce a rewarding effect as revealed by the CPP testing, which may account, at least in part, for its suppressive effect on morphine induced CPP, (b) the suppressive effect of PES on morphine induced CPP is not due to a deteriorating effect on the ability of spatial memory.

Abstract
Experimental efforts for understanding the mechanisms of electroacupuncture (EA) for opiate addiction are partially hampered by restraint stress. In unrestrained animals, it is difficult to perform EA stimulation at acupuncture points frequently selected on the four limbs. The present study was performed to evaluate the effect of EA at the acupuncture point Shen-Shu (BL.23) on morphine withdrawal signs and c-Fos expression of the amygdala in freely moving rats or restrained rats. We applied immunohistochemistry to detect c-Fos-positive nuclei. Corticosterone levels and behavioral responses were measured during EA stimulation. The needles were bilaterally inserted and fixed at BL.23, and 100-Hz electric stimulation was conducted 30 min before naloxone-precipitated withdrawal. In both freely moving rats and restrained rats, EA significantly reduced the signs of morphine withdrawal. Notably, EA stimulation in freely moving rats attenuated c-Fos expression in the central nucleus of the amygdala while EA in restrained animals increased this response. In addition, the restrained rats emitted greater levels of vocalization and facial expression than freely moving rats during EA stimulation. Corticosterone levels were also significantly higher in restrained animals after EA stimulation. The new EA paradigm demonstrated in the present study might help the analysis of certain physiological responses induced by EA that would otherwise have been hindered by restraint stress.

The present study was performed to elucidate if preproenkephalin (PPE) and preprodynorphin (PPD) mRNAs in the nucleus accumbens (NAc) play a role in this event. Rats were trained with morphine for 4 days to establish CPP paradigm. They were then given 15-min test once a day for eight consecutive days for extinction trial. Twenty-four hours after the 8th session of extinction trials, rats were given peripheral electrical stimulation (PES) at 2 or 100 Hz once a day for 3 days, then a morphine-priming injection at a dose of 1, 2, or 4 mg/kg to reinstate the extinguished CPP. At the end of the experiment, PPE and PPD mRNA levels in the nucleus acccumbens (NAc) were determined by the semiquantitative RT-PCR technique. The results showed that PES at 2- and 100-Hz administered 30 min a day for 3 days suppressed both the expression of morphine-induced CPP and the reinstatement of extinguished CPP. PES at 2 Hz increased preproenkephalin (PPE) mRNA levels, whereas PES of 100 Hz that of preprodynorphin (PPD) mRNA levels in the NAc. These findings suggest that enkephalin and dynorphin in NAc may play important roles in the mechanisms underlying the inhibitory effect of PES on the expression and reinstatement of morphine-induced CPP in rats.

Abstract
Clinical trials are currently underway to determine the effectiveness of acupuncture in the treatment of drug abuse. However, there are still many unanswered questions about the basic mechanisms of acupuncture. Studies have shown that the GABA(B) receptor system may play a significant modulatory role in the mesolimbic system in drug abuse, including ethanol. The in vivo microdialysis study was designed to investigate the effect of acupuncture on acute ethanol-induced dopamine release in the nucleus accumbens and the potential role of the GABA(B) receptor system in acupuncture. Male Sprague-Dawley rats were administered with the highly selective GABA(B) antagonist SCH 50911 (3 mg/kg, i.p.) 1h prior to an intraperitoneal injection of ethanol (1 g/kg). Immediately after ethanol treatment, acupuncture was given at bilateral Shenmen (HT7) points for 1min. Acupuncture at the specific acupoint HT7, but not at control points (PC6 or tail) significantly decreased dopamine release in the nucleus accumbens. Inhibition of dopamine release by acupuncture was completely prevented by SCH 50911. These results suggest that stimulation of specific acupoints inhibits ethanol-induced dopamine release by modulating GABA(B) activity and imply that acupuncture may be effective in blocking the reinforcing effects of ethanol.
