RESUMEN
Migraine is a neurological disorder characterized by attacks of moderate or severe headache and various neurological symptoms. Acupuncture, as a commonly used non-pharmacological therapy, has the advantage of obvious therapeutic effect and few side effects in the prevention and treatment of migraine. But the underlying mechanism of acupuncture on migraine remains unclear. Recently, advances in neuroimaging technology have helped to objectively assess the effect of acupuncture on treating migraine and offered new opportunities to explore the central mechanism of acupuncture on treating migraine. In order to better understand the current status of neuroimaging studies on the therapeutic mechanism of acupuncture on migraine and shed light on future research, this review aims to overview the neuroimaging studies in recent 10 years from two aspects: (1) Central mechanism of acupuncture on treating acute migraine attack; (2) Central mechanism of acupuncture on preventing migraine attack.

BACKGROUND: As a central nervous system disease, migraine often coexists with gastrointestinal disorders, which suggests a disruption of brain-gut regulation. Clinical studies have confirmed that acupuncture and flunarizine not only alleviate migraine attacks but also substantially inhibit accompanying gastrointestinal symptoms. However, it is still not clear how acupuncture and flunarizine regulate the interactions of brain, gut, and microbiome. Therefore, this study will combine neuroimaging technology and gut microbiota detection technology to explore and compare the effects and brain-gut modulating mechanisms of acupuncture and flunarizine for migraine. METHODS: This randomized clinical trial will recruit 66 patients with migraine without aura. Participants will be randomly assigned in a 1 : 1 ratio to an acupuncture group or a control group. The acupuncture treatment strategy is based on experience from our previous study and consensus meetings with clinical experts. Patients will receive 12 sessions of manual acupuncture treatment (once every other day to a total of three times per week, followed by a 2-day break). Flunarizine will be administered at a dose of 5 mg daily in the control group. Participants in both groups will receive treatment for a period of 4 weeks. The primary outcome is the change in frequency of migraine attacks, and the secondary outcomes include the changes in migraine days (days on which migraine attacks occurred), average migraine severity, gastrointestinal symptoms, psychiatric symptoms, and quality of life. Fresh stool samples will be collected, and 16S ribosomal RNA gene sequencing analysis will be used for gut microbiota. Magnetic resonance imaging will be applied to detect between-group changes in brain function. The abovementioned indicators will be collected at baseline, after a 4-week intervention, and at the 12-week follow-up. Discussions. From the perspective of brain-gut regulatory mechanisms, we will combine brain neuroimaging and gut microbiological data to partially reveal the similarities and differences of acupuncture and flunarizine on the treatment of migraine. The trial is registered with ChiCTR2000034417.
RESUMEN
Based on the internationally-recognized Consolidated Standards for Reporting of Trials (CONSORT) statement and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA), the reported quality of randomized controlled trials (RCTs) of acupuncture for cancer pain during last 10 years were evaluated. The RCTs of acupuncture for cancer pain were searched by computer. The English databases included PubMed and EMbase while the Chinese databases included CNKI, Wanfang, VIP and SinoMed. The publication date of the literature was from March 2009 to March 2019. As a result, 22 Chinese RCTs and 13 English RCTs were included. According to the CONSORT statement, among the Chinese studies, 1 RCT reported primary and secondary outcomes, 8 RCTs reported randomization, none of RCTs reported allocation concealment and blind method, and 4 RCTs reported baseline data; among the English studies, 8 RCTs reported primary and secondary outcomes, 8 RCTs reported randomization, 6 RCTs reported described allocation concealment, 7 RCTs reported blind method, and 13 RCTs reported baseline data. According to the STRICTA statement, among the Chinese studies, 17 RCTs reported the name of acupoints, 6 RCTs reported depth of insertion, 17 RCTs reported acupuncture response sought, and none of RCTs reported the qualifications of acupuncturists; among the English studies, 12 RCTs reported the name of acupoints, 7 RCTs reported depth of insertion, 8 RCTs reported acupuncture response sought, and 7 RCTs reported the qualifications of acupuncturists. The Chinese RCTs have more detailed description of acupuncture intervention and theory, but not enough attention is paid to methodological description such as randomization, blindness, data analysis. On the other hand, the English RCTs have better description of methodology, but the description of theory and details of acupuncture is relatively weak. It is concluded that more efforts were needed to further improve the clinical trial design according to the CONSORT statement and STRICTA statement to improve the quality of clinical evidence.

The internationally-accepted Consolidated Standards for Reporting of Trials (CONSORT) and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) were applied to evaluate the literature quality of randomized controlled trials (RCTs) regarding acupuncture for chronic neck pain in past 10 years. The literature of RCTs regarding acupuncture for chronic neck pain was searched by computer; the English literature was searched in PubMed and EMbase, while the Chinese literature was searched in CNKI, Wanfang database, VIP database and China Biomedical Literature Database. The literature published from January 2008 to January 2018 was searched. As a result, 29 Chinese articles and 10 English articles were included. According to CONSORT, among Chinese articles, 28 articles (96.6%) described baseline data, 23 articles (79.3%) described randomization, 0 articles (0.0%) described allocation concealment, 3 articles (10.3%) described blind method; among English articles, 6 articles (60.0%) described baseline data, 8 articles (80.0%) described randomization, 8 articles (80.0%) described allocation concealment, and 7 articles (70.0%) described blind method. According to STRICTA, among Chinese articles, 8 articles (27.6%) described needle instrument selection, 18 articles (62.1%) described needle depth, 24 articles (82.8%) described needling sensation, and 0 articles (0.0%) described acupuncturist' qualifications; among English articles, 5 articles (50.0%) described needle instrument selection, 8 articles (80.0%) described needle depth, 3 articles (30.0%) described needling sensation, and 4 articles (40.0%) described acupuncturist' qualifications. In conclusion, the reporting of acupuncture details in Chinese literature is superior to that in English literature, while the reporting of trial design in English literature is slightly superior to that in Chinese literature. Moreover, both Chinese and English literature need to further improve clinical trial design to improve the reporting quality of clinical evidence based on CONSORT and STRICTA.
