Acupuncture Mechanisms: Anesthesia, Analgesia and Protection on Organ Functions. This review summarizes research progress on the mechanisms of acupuncture for analgesia; its protection against organ function injury in anesthesia; and its effect on analgesia, immunomodulation, neuroendocrine regulation and multiple organ protection. The current evidence supports that acupuncture analgesia and its organ protection in anesthesia is associated with the integration of neuroendocrine-immune networks at the level of neurotransmitters, cytokines, hormones, neuronal ensembles, lymphocytes, and endocrine cells. Although the mechanisms of acupuncture analgesia and its organ protection are still not completely understood, basic as well as clinic research on the mechanisms and applications of acupuncture and related techniques are being carried out.
Acupuncture For Military PTSD Found Effective. Acupuncture effectively treats posttraumatic stress disorder (PTSD). Researchers conducting a randomized controlled study of active duty US military service personnel concludes that acupuncture significantly improves patient outcomes for PTSD patients. Acupuncture also induced secondary improvements: reduced depression and pain, improved mental and physical health functioning.
Low frequency (electroacupuncture) or manual acupuncture stimulates nerve fibers thus affecting large numbers of neurotransmitter systems in the brain and spinal cord, such as acetylcholine, opioids, and serotonin. Acupuncture sensitive neurons have been identified in the brain. Acupuncture has been shown to affect signalling molecules in many animal model studies. Research has found that acupoints have increased conductance, decreased resistance/impedance, elevated capacitance, and higher potential compared to controls. Yet there is still a lack of research results which adequately explain the physiological basis of meridians and the 'qi' that moves along them. Although qi and the flow of it through meridians has not been directly measured, bioenergy can be measured. Using electromyography, researchers have shown that electric energy caused by acupuncture does in fact travel along pathways roughly corresponding to meridians. This energy follows blood flow that was initiated and stimulated by acupuncture. For more information on the use of electromyography, EEG, Photon Migration Spectroscopy, Laser Doppler Flometry, and Gas Discharge Visualization to study Acupuncture, Qigong, andTtai Chi see Publications on the Laboratory for Mind-Body Signaling & Energy Research website.
Researchers at Penn Medicine and other institutions found that electro-acupuncture (“real” acupuncture) helped reduce joint pain by as much as 40 percent in women with breast cancer, whether the patient expected it to work or not. The study also found that “sham” acupuncture – which involves nonpenetrative needles and no electrical stimulation – provided pain reduction as high as 80 percent if patients had a high degree of expectation that it would work. The study results provide important implications for future treatment of breast cancer patients with joint pain. Patients who reported pain relief had increased expectancy that it would continue to work over the course of their acupuncture treatment as compared with nonresponders, suggesting that positive responses during the process of real acupuncture increased the expectations of further positive outcomes. “These findings certainly challenge the notion held by some that acupuncture is ‘all placebo,’” said the study’s lead author Joshua Bauml, MD, an assistant professor of Medicine in the Abramson Cancer Center. “If it were ‘all placebo,’ patients receiving real acupuncture who had low expectations that it would work would report little or no reductions in pain. But that’s not the case.” Sham acupuncture only produced clinically important pain reduction for those with high onset expectancy. But patients with the highest expectation that it would work reported as much as 80 percent reductions in pain – twice the rate of patients receiving real acupuncture. Sham acupuncture patients with low baseline expectancy scores did not report any significant pain reduction.

PDQ Cancer Information Summary for Acupuncture - Patient Version. The PDQ cancer information summaries are peer-reviewed, evidence-based summaries on topics including adult and pediatric cancer treatment, supportive and palliative care, screening, prevention, genetics, and complementary and alternative medicine. There are versions for patients and professionals. The summaries come from the National Cancer Institute's comprehensive cancer database, PDQ (Physician Data Query). This PDQ cancer information summary has current information about the use of acupuncture in the treatment of people with cancer. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care. Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Date Last Modified") is the date of the most recent change. The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Cancer Complementary and Alternative Medicine Editorial Board.
Over the years there has been substantial debate about whether acupuncture really works for chronic pain. Research from an international team of experts adds to the evidence that it does provide real relief from common forms of pain. The team pooled the results of 29 studies involving nearly 18,000 participants. Some had acupuncture, some had “sham” acupuncture, and some didn’t have acupuncture at all. Overall, acupuncture relieved pain by about 50%. More.
Harvard Medical School review presents the latest available evidence regarding the use of acupuncture for cancer pain. Cancer pain is one of most prevalent symptoms in patients with cancer. The National Comprehensive Cancer Network guidelines for adult cancer pain recommends acupuncture, as one of several integrative interventions, in conjunction with pharmacologic intervention as needed. It also provides "actionable" acupuncture protocols for specific cancer pain conditions and related symptoms in order to provide more clinically relevant solutions for clinicians and cancer patients with pain. These conditions include postoperative cancer pain, postoperative nausea and vomiting, postsurgical gastroparesis syndrome, opioid-induced constipation, opioid-induced pruritus, chemotherapy-induced neuropathy, aromatase inhibitor-associated joint pain, and neck dissection-related pain and dysfunction.
In 1997, the National Institutes of Health issued a Consensus Statement which officially approved acupuncture for use in medical treatment.

Characterizing acupuncture stimuli using brain imaging with FMRI - a systematic review and meta-analysis of the literature. Brain response to acupuncture stimuli encompasses a broad network of regions consistent with not just somatosensory, but also affective and cognitive processing. Acupuncture can modulate the activity within specific brain areas. Media Article and Image: Where acupuncture pricks the brain.
Pain and sensory detection threshold response to acupuncture is modulated by coping strategy and acupuncture sensation. The interaction between psychological coping strategy and acupuncture sensation intensity can differentially modulate pain and sensory detection threshold response to EA. In a clinical context, our findings suggest that instructions given to the patient can significantly affect therapeutic outcomes and the relationship between acupuncture intensity and clinical response. Specifically, acupuncture analgesia can be enhanced by matching physical stimulation intensity with psychological coping strategy to acupuncture contexts.
Acupoints Initiate the Healing Process. Needling is the first step of traditional acupuncture therapy. Needling reactions- neuronal, biophysical, and biochemical-are the beginning of healing. The messengers of the three reactions involved may include neurotransmitters, cytokines, hormones, and inflammatory factors. Healing may be potentiated through these messengers in neuronal and humoral pathways. The reactions manifest as erythema and De Qi-both of which are common phenomena used as positive signs in acupuncture treatment.
Systematic review finds acupuncture is helpful in managing symptoms in cancer patients. Acupuncture should be considered for symptom management where there are limited treatment options, using current peer-reviewed guidelines and clinical reasoning.

Proposed catalog of the neuroanatomy and the stratified anatomy for the 361 acupuncture points of 14 channels. In spite of the extensive research on acupuncture mechanisms, no comprehensive and systematic peer-reviewed reference list of the stratified anatomical and the neuroanatomical features of all 361 acupuncture points exists. This study creates a reference list of the neuroanatomy and the stratified anatomy for each of the 361 acupuncture points on the 14 classical channels and for 34 extra points. This is a step towards western medical standardization of acupuncture points.

Acupuncture, Connective Tissue, and Peripheral Sensory Modulation. Although considerable controversy surrounds the legitimacy of acupuncture as a treatment, a growing literature on the physiological effects of acupuncture needling in animals and humans is providing new insights into basic cellular mechanisms including connective tissue mechanotransduction and purinergic signaling. This review summarizes these findings and proposes a model combining connective tissue plasticity and peripheral sensory modulation in response to the sustained stretching of tissue that results from acupuncture needle manipulation.
Electrical properties of acupuncture points and meridians: a systematic review. Twenty-four articles from twenty-nine studies in publications from 1970 to 2007 were searched to support or refute the claim that acupuncture points or meridians possess distinct electrical properties. The reported electrical associations at acupuncture points include increased conductance, decreased resistance/impedance, elevated capacitance, and higher potential compared to controls.
New findings of the correlation between acupoints and corresponding brain cortices using functional MRI. The results obtained demonstrate the correlation between activation of specific areas of brain cortices and corresponding acupoint stimulation predicted by ancient acupuncture literature.
Analgesic acupuncture effects outlast the needling period. Pain-associated brain areas were modulated in direct response to a preceding acupuncture treatment.
Traditional acupuncture triggers a local increase in adenosine in human subjects.There is increasing evidence that local chemical production of adenosine via connective tissue wrapping around needles is one factor that contributes to the pain relieving mechanism of acupuncture in human subjects.
Neurobiological mechanisms of acupuncture analgesia. Acupuncture has been proven by biochemical, immunohistochemical, molecular biological and neurophysiological investigations. It has been shown that short term acupuncture analgesia is mediated by an activation of endogenous antinociceptive systems and descending inhibitory systems. Long term effects cannot be explained sufficiently by experimental results; however, they suggest an involvement of long term inhibitory synaptic modification at spinal cord neurons and clinical and radiological findings indicate limbic system modulation.
