In clinical practice, acupuncture anesthesia presents a multitude of advantages, pivotal among these being Body System Protection. This technique supports the body's natural defenses, reducing the physiological stress often associated with surgical procedures. By modulating the body's response to pain, acupuncture anesthesia allows for a lower Dosage of Medication, significantly reducing the potential for drug-related side effects. Furthermore, this approach plays a crucial role in Emotion Regulation, helping patients maintain a calm and stable emotional state, which is essential for a positive surgical outcome. The impact of acupuncture on the nervous system not only aids in Pain Relief but also promotes Enhanced Recovery After Surgery. Patients tend to experience faster recuperation times, attributed to the holistic nature of this method. Additionally, acupuncture anesthesia is associated with a Lower Incidence of Side Effects compared to conventional anesthetics. Its ability to modulate and balance the body's responses makes it an invaluable tool in the realm of modern medicine, offering a safer, more patient-centered approach to pain management and recovery.

35269431 However, using CRO to shield the degranulation of MCs in the treated acupoint can significantly weaken the acupuncture analgesic effect (Figure 6a). Cells. 2022 Feb 25;11(5):809. doi: 10.3390/cells11050809. Analgesic Effect Review
35269431 The critical findings are that in non-painful WsRC−+/+ rats, although acupuncture (10 min, ST36) still can produce an analgesic effect for mechanical pain, the effect is substantially decreased compared with wild-type rats.

35647012 Compared with conventional acupuncture, EA is more effective and convenient, so EA is often used to assist anesthesia and analgesia in various surgical procedures.. It has been reported that in a variety of local anesthesia surgerys, EA can significantly enhance the perioperative analgesic effect, improve hemodynamic abnormalities, and reduce the incidence of adverse reactions after anesthesia.

23573118 The fact that the acupuncture treatment of Groups 1 and 2 differ in their analgesic effects in the present study indicates that it considerably matters which acupoints are used and contradicts the view that acupuncture might only mediate nonspecific skin stimulation, which may or may not exceed placebo effects.

23573118 As imaging studies have delivered evidence of acupoint-specific functional magnetic resonance imaging patterns and the selection of acupoints presented the only systematic difference between acupuncture treatment in Groups 1 and 2, the observable difference in analgesic effects can be attributed to the summation effect of all twelve individual acupoint-specific reactions.

15937559 The unequal sex distribution between the two groups (female prevalence in the AA group and male prevalence in the control group) might only have diminished the difference between the groups in terms of ibuprofen requirement (suggested analgesic effect of AA), since women experience more acute pain than men and they also require more non-steroidal anti-inflammatory drugs.

32062864 It is well known that the analgesic mechanism of acupuncture is related to endogenous opioid system activation.14 Laboratory studies have also shown that continuous electrical stimulation at one frequency could induce tolerance and weaken the analgesic effect.15, 16 Thus, dilatational wave stimulation has been popularly used in recent years, since it can promote the release of all three endogenous opioid peptides and delay analgesia tolerance under continuous electroacupuncture (EA) or TEAS.17 Highxe2x80x90intensity EA produces more extensive and enduring analgesic effect than lowxe2x80x90intensity EA due to the activation of brainstem negative feedback system by Axcexb4 fibers and also by C fibers under noxious stimulation.

25481535 These results suggest that the serotonergic system plays a major role in mediating the analgesic effect of BVA on oxaliplatin-induced cold allodynia. BMC Complement Altern Med. 2014 Dec 6;14:471. doi: 10.1186/1472-6882-14-471. Analgesic Effect Mechanism
25481535 Unlike the EA-induced analgesia mainly involving the endogenous opioid system, the analgesic effects of BVA are known to be mediated by the non-opioid, descending noradrenergic system. BMC Complement Altern Med. 2014 Dec 6;14:471. doi: 10.1186/1472-6882-14-471. Analgesic Effect Mechanism
25481535 This implies that BVA exerts a potent analgesic effect on oxaliplatin-induced cold allodynia by activating the spinal serotonergic inhibitory system. BMC Complement Altern Med. 2014 Dec 6;14:471. doi: 10.1186/1472-6882-14-471. Analgesic Effect Mechanism

22550540 However, there have been no reports that electroacupuncture at BL60 by itself has an analgesic effect on inflammatory pain. Evid Based Complement Alternat Med. 2012;2012:324039. doi: 10.1155/2012/324039. Epub 2012 Apr 5. Analgesic Effect Inflammatory Pain Mechanism
22550540 In electroacupuncture treatment, it has been shown that low-frequency stimulation produces prolonged analgesic effects relatively late in electroacupuncture; however, high-frequency stimulation produces short-lasting analgesic effects immediately after initiation of electroacupuncture.

24757373 Even though there is no direct evidence regarding the analgesic effect of BL60 stimulation, the pain-relieving effect of acupuncture stimulation at acupoints on biphasic pain behavior in formalin test may be limited and mainly suppress the late phase in formalin test which reflects the injury-induced spinal sensitization.

35416841 Among these, adenosine A1 receptors are widely distributed in the spinal dorsal horn neurons, and activation of adenosine A1 receptors can inhibit the excitability of spinal neurons and achieve analgesic effects.

35416841 Moreover, our own previous studies showed that adenosine content in the spinal cord of CCI rats can increase 60 min after EA, while silencing the adenosine A1 receptors can reverse the analgesic effect of EA. Arq Neuropsiquiatr. 2022 Mar;80(3):289-295. doi: 10.1590/0004-282X-ANP-2021-0149. Analgesic Effect Mechanism
35416841 At the same time, the MWT and TPT levels in the EA + AOPCP group were significantly lower than those in the EA and EA + NS groups, which provided strong evidence that AOPCP could reverse the analgesic effect of EA on CCI rats.

35416841 Therefore, we hypothesized that EA may increase the level of adenosine and produce analgesic effects through upregulating the expression of 5'-NT in the spinal cord of CCI rats. Arq Neuropsiquiatr. 2022 Mar;80(3):289-295. doi: 10.1590/0004-282X-ANP-2021-0149. Analgesic Effect Mechanism
35416841 However, our study had some shortcomings: we only used AOPCP to inhibit the activity of 5'-NT; this could only demonstrate the involvement of 5'-NT in the analgesic effect of EA at the pharmacological level.

35416841 In conclusion, we believe that EA can upregulate the expression of 5'-NT in the spinal cord of CCI rats and that AOPCP can significantly reverse the upregulation of adenosine content in the spinal cord of CCI rats and the analgesic effect of EA on CCI rats, while exogenous adenosine supplementation can restore the analgesic effect of EA.

25368638 Previous studies addressing the analgesic effect of acupuncture mainly focused on purine and a single purine receptor; no studies have examined the possible influence of synergism or antagonism with other receptors. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Mechanism
25368638 Electroacupuncture may induce an analgesic effect in neuropathic pain by influencing both purinergic A1 and P2X purinoceptor 3 (P2X3) receptors simultaneously. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Neuropathic Pain Mechanism

25368638 Whereas the stimulation of A1 receptors results in analgesic effects in a wide range of animal models, in rats lacking the A1 receptor there is an enhanced response to nociceptive stimuli. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Mechanism
25368638 Electroacupuncture treatment produces a long-lasting analgesic effect on neuropathic pain and increases expression of P2X3 receptors in the midbrain periaqueductal gray matter, which potentiates the function of the purinergic signaling system at the supraspinal level and provides a rational basis for explaining the analgesic effect of electroacupuncture. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Neuropathic Pain Mechanism
25368638 The analgesic effects of peripheral, spinal and supraspinal A1 receptors are well established, and an A1 receptor agonist has been found to substantially reduce inflammatory and neurogenic pain; also, the suppression of pain mediated by electroacupuncture requires adenosine A1 receptor expression. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Mechanism
25368638 Although the analgesic effect of electroacupuncture is well documented, little is understood about its biological basis. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Mechanism
25368638 The primary mechanism implicated in the analgesic effect of electroacupuncture involves release of endogenous opioid peptides in response to the long-lasting activation of ascending sensory tracts during stimulation. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Mechanism
25368638 Also, it has been suggested that the analgesic effects of electroacupuncture are associated with its ability to counter-regulate spinal glial activation. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Mechanism

25368638 Therefore, the ATP release induced by electroacupuncture does not activate P2X3 receptors and so does not exert an anti-analgesic effect. Neural Regen Res. 2012 Nov 25;7(33):2618-23. doi: 10.3969/j.issn.1673-5374.2012.33.007. Analgesic Effect Mechanism
25368638 In patients with chronic neuropathic pain, adenosine compounds appear to mediate their analgesic effects through A1 receptor-related modulation of central sensitization at spinal or supraspinal levels.

23737830 This restrained EA method had been suggested to cause stress, and its analgesic effects might hardly be differentiated from stress-induced analgesia (SIA). Evid Based Complement Alternat Med. 2013;2013:404956. doi: 10.1155/2013/404956. Epub 2013 May 12. Analgesic Effect Mechanism
23737830 In addition, accumulating evidence suggests that different stimulating parameters, such as current intensity, frequency, and location, all significantly affect the analgesic effects of EA.
