It aims at treating a range of clinical conditions, especially used for pain relief. Modern scientific research studies have revealed the analgesia mechanisms of acupuncture. Our purpose was through literature retrieval to describe the current status of acupuncture therapy in peripheral neuropathic pain in China, to promote the spread and development of acupuncture therapy in relieving peripheral neuropathic pain. Methods: An electronic search was conducted using China National Knowledge Infrastructure (CNKI), with the medical heading subject ‘acupuncture’ and ‘neuralgia’ . Then we summarized the top three diseases in acupuncture therapies. Lastly we selected high-quality observational studies and RCT articles of randomized controlled trials in acupuncture,which were in line with reporting standards (STRICTA) . Results: 1250 studies and 13 diseases retrieved from CNKI . The occurrence frequencies with acupuncture therapies in peripheral neuropathic pain were sciatica, postherpetic neuralgia, trigeminal neuralgia. And then introduced these diseases from the aspects of interventions, acupuncture points choice, course of treatment, the effective targets. Conclusion: Acupuncture therapy has the advantage of relieving pain, decreasing side effects, and promoting the quality of life than western medicine, and combined acupuncture therapies could increase efficacy of neuropathic pain. Key words: Painful Peripheral Neuropathy, acupuncture therapy, treatment status 1 | Scholoxy Publications | www.scholoxy.org Volume 1 | Issue 4 Background Peripheral neuropathy is damage to, or disease function, such as Yanhusuo, Wuzhuyu, Wulingzhi, affecting the peripheral nervous system, which may Moyao, and so on. Some of the herbs have not been impair the function of peripheral nervous system. documented for their analgesic function by ancient Common causes include systemic diseases (such as herbal medicine books, but they were found to have diabetes), infection, metabolic abnormalities and analgesic effects in experimental studies, such as immune system disease[1].The estimated prevalence Lingzhi, Dangshen, Haishen, Tufuling, of peripheral neuropathies in the general population is Tianzhuhuang[7]. approximately 2%, and in adults over 55 years of age action slowly, and can't achieve the analgesic effect it can reach 8% [2], and its main clinical manifestations are motion disorders and paresthesia[1]. However, Chinese herbs take on immediately. In china, non-drug therapy showed an Pain is the advantage in the treatment of pain, the main therapy main symptom of paresthesia. The experts consensus is acupuncture, which is the stimulation of specific revised in 2013 classified them as neuropathic pain; acupuncture points along the skin of the body, symptoms included stabbing pain, burning pain, involving various methods includes moxibustion, radiating pain which patients could hardly bear and acupoints injection, pricking blood, cupping, acupoints seriously affected the patient's quality of life [3]. Most application, transcutaneous electrical nerve common diseases which could cause peripheral stimulation, acupoints catgut implantation. It also neuropathic pain are sciatica, postherpetic neuralgia, includes other physical treatment methods such as trigeminal neuralgia. The principle of treatment is massage, infrared spectroscopy treatment, drug analgesic therapy, on the basis of active treatment of fumigation and so on. These therapies take effects by primary diseases. The therapies can be roughly opening the meridians and collaterals, regulating of Qi divided into drug therapy and non-drug therapy. In and blood, with less side effects, easy to operate, China, the drug treatments can be divided into affordable, which relieve pain and improve quality of Western drugs and Chinese herbs. Western drugs life. This article focuses on the status of acupuncture mainly include: Ca+ Channel Modulators (Pregabalin therapy on peripheral neuropathic pain in China. and Gabapentin), Tricyclic Antidepressants (TCA), Serotonin(5-HT) and Selective Serotonin Methods Norepinephrine Reuptake Inhibitor(SSNRI), Local An electronic search was conducted using China lidocaine, Carbamazepine, Oxcarbazepine, Opioid National Knowledge Infrastructure(CNKI), with the Analgesics(morphine, oxycodone, methadone), etc[3]. medical But the western drugs for analgesia can produce ‘neuralgia’ . Then we summarized the top three more side effects at the same time, such as nausea diseases in acupuncture therapies. Lastly we selected and drug high-quality observational studies and RCT articles of addiction , and some may lead to kidney dysfunction randomized controlled trials in acupuncture,which in severe cases[4-6]。Chinese herbs could bring good were in line with reporting standards (STRICTA) [8] . vomiting, gastrointestinal discomfort, heading subject ‘acupuncture’ and clinical effects. More than 300 kinds of Chinese herbs have been demonstrated to have analgesic effect. Some of the herbs are clearly documented in the ancient herbal medicine books for their analgesic 2 | Scholoxy Publications | www.scholoxy.org Volume 1 | Issue 4 Result diseases, and the most common diseases which required the acupuncture therapy were chosen, such There were 1250 studies and 13 diseases retrieved from CNKI. The occurrence frequencies with acupuncture therapies in peripheral neuropathic pain are summarized as follows (Figure 1). This article is as sciatica, postherpetic neuralgia, trigeminal neuralgia. And then these diseases were introduced from the aspects of interventions, therapies, course of treatment, the effective targets[8] based on the occurrence frequencies of these 3% 1% 1% 0% 0% 0% 0% 2% 1% 1% Sciatica Postherpetic neuralgia 36% 24% Trigeminal neuralgia Occipital neuralgia Great occipital neuralgia 31% Intercostal neuralgia Figure 1 The occurrence frequencies Acupuncture therapy for sciatica showed that acupuncture improved blood circulation, increased the body's pain threshold and pain Sciatica is pain of the nerve pathway and its distribution areas. The symptoms are paroxysmal and persistent pain in the hip, the back of the thighs, the lateral of cruel region and border of foot. The nature of pain is mostly dull pain, there might be burning or stabbing pain sometimes. The reason for it is the pathological changes of the sciatic nerve and tolerance threshold, relieved muscle spasms and pain, promoted the functional recovery of body[9]. Statistical results show that the top three therapies for sciatica, respectively is: acupuncture, acupuncture plus medicine and warming acupuncture(Figure 2), we summarized the therapies of acupuncture for sciatica as follows (Table1) surrounding structures[1] , Related systematic reviews 3 | Scholoxy Publications | www.scholoxy.org Volume 1 | Issue 4 Figure 2 therapies for sciatica Table 2 The acupuncture therapies for sciatica Source Invention Therapies MA Zhibian(BL54),Huantiao(GB30),Yinmen( BL37),Weizhong(BL40),Chenshan(BL57), Konglun(BL60),Xuanzhong(GB39),Ahshipoint .

Acupuncture therapy for Trigeminal neuralgia high frequency, which lies in the sixth position in the acupuncture disease spectrum[18]. And the system Trigeminal neuralgia is a chronic recurrent pain condition that affects the trigeminal nerve, which carries sensation from face to brain. The episodes of intense pain may occur paroxysmally and might be reoccuring[17]. The rate of incidence is higher among the middle aged people. Clinical reports of acupuncture therapy in trigeminal neuralgia have a 6 | Scholoxy Publications | www.scholoxy.org reviews indicated that acupuncture is of similar efficacy as carbamazepine but with fewer adverse effects in treatment of trigeminal neuralgia [19]. The top three therapies , respectively are: acupuncture and moxibustion, acupuncture plus medicine and acupoint injection plus acupuncture(Figure 4). the acupuncture therapies are summarized as follows (Table3).

Secondly, the choice of acupuncture points has a certain regularity for the pain of peripheral Through the summary about the acupuncture treatment of these diseases , we found that acupuncture treatment in neuropathic pain has certain characteristics and regularities. Firstly, acupuncture is not limited to filiform needles, often with other therapies like acupoint injection, auricular-plaster, acupoint catgut embedding, bloodletting, cupping, transcutaneous electrical nerve stimulation, TDP (specific electromagnetic wave treatment machine), etc. Combination therapies can achieve the efficiency neuropathy. The points of primary disease should be selected firstly , and compared with the points in the pain area and specific points in treatment, such as when we treated the Huantiao(GB30) sciatica, should Zhibian(BL54), be selected; Weizhong(BL40), Chenshan(BL57) could be selected too, and Ashi points were used widely. In addition, acupoints could be selected according to nerve branches, such as trigeminal neuralgia and postherpetic neuralgia, we could select the points in the distribution of skin lesion. Lastly, acupuncture therapy 8 | Scholoxy Publications | www.scholoxy.org has the advantage of relieving pain, Volume 1 | Issue 4 decreasing side effects, and promoting the quality of and to promote the spreading and development of life acupuncture abroad. than western medicine, and combined acupuncture therapies could result in increased efficacy.
