The long-term prophylactic effects of acupuncture for migraine are uncertain.OBJECTIVE To investigate the long-term effects of true acupuncture compared with sham acupuncture and being placed in a waiting-list control group for migraine prophylaxis. DESIGN, SETTING, AND PARTICIPANTSThis was a 24-week randomized clinical trial (4 weeks of treatment followed by 20 weeks of follow-up). Participants were randomly assigned to true acupuncture, sham acupuncture, or a waiting-list control group. The trial was conducted from October 2012 to September 2014 in outpatient settings at 3 clinical sites in China. A total of 249 participants 18 to 65 years old with migraine without aura based on the criteria of the International Headache Society, with migraine occurring 2 to 8 times per month.INTERVENTIONS Participants in the true acupuncture and sham acupuncture groups received treatment 5 days per week for 4 weeks for a total of 20 sessions. Participants in the waiting-list group did not receive acupuncture but were informed that 20 sessions of acupuncture would be provided free of charge at the end of the trial. MAIN OUTCOMES AND MEASURESParticipants used diaries to record migraine attacks. The primary outcome was the change in the frequency of migraine attacks from baseline to week 16. Secondary outcome measures included the migraine days, average headache severity, and medication intake every 4 weeks within 24 weeks.RESULTS A total of 249 participants 18 to 65 years old were enrolled, and 245 were included in the intention-to-treat analyses. One hundred eighty-nine (77.1%) were women. Baseline characteristics were comparable across the 3 groups. The mean (SD) change in frequency of migraine attacks differed significantly among the 3 groups at 16 weeks after randomization (P < .001); the mean (SD) frequency of attacks decreased in the true acupuncture group by 3.2 (2.1), in the sham acupuncture group by 2.1 (2.5), and the waiting-list group by 1.4 (2.5); a greater reduction was observed in the true acupuncture than in the sham acupuncture group (difference of 1.1 attacks; 95% CI, 0.4-1.9; P = .002) and in the true acupuncture vs waiting-list group (difference of 1.8 attacks; 95% CI, 1.1-2.5; P < .001). Sham acupuncture was not statistically different from the waiting-list group (difference of 0.7 attacks; 95% CI, −0.1 to 1.4; P = .07).CONCLUSIONS AND RELEVANCE Among patients with migraine without aura, true acupuncture may be associated with long-term reduction in migraine recurrence compared with sham acupuncture or assigned to a waiting list.TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01687660

A bout 6%-8% of men and 16%-18% of women in the United States and England experience migraines, with or without an aura.1,2 A prevalence of 1% has been reported in mainland China, 3 compared with 4.7% in Hong Kong and 9.1% in Taiwan.4,5 A recent Cochrane meta-analysis suggests that acupuncture as migraine prophylaxis is safe and effective and should be considered as a treatment option for willing patients. Although the specific effects acupuncture are controversial, acupuncture, as it is currently practised, clearly differentiates between real acupuncture points and nonacupuncture points. The Chinese Government launched the National Basic Research Program to obtain more data about the specificity of acupuncture points. 7Trials from Italy and Brazil 8,9 showed that acupuncture was more effective than sham acupuncture in preventing migraines, but other trials have reported no differences. [10][11][12][13] There is no evidence that one acupuncture strategy is more effective than another for treating migraines. According to acupuncture theory, a headache on the lateral side is usually defined as a Shaoyang headache. In Jinkuiyi, 14 migraines are said to affect the yang meridians (including the Taiyang, Yangming and Shaoyang meridians). In Lingshu, 15 the Shaoyang meridians are said to go through the lateral side of the body, therefore the Shaoyang meridians are thought to be superior for treating migraines. Some points on the Shaoyang meridians are regarded as being more specific for migraines than other points. Research CMAJ Background: Acupuncture is commonly used to treat migraine. We assessed the efficacy of acupuncture at migraine-specific acupuncture points compared with other acupuncture points and sham acupuncture. Methods:We performed a multicentre, singleblind randomized controlled trial. In total, 480 patients with migraine were randomly assigned to one of four groups (Shaoyangspecific acupuncture, Shaoyang-nonspecific acupuncture, Yangming-specific acupuncture or sham acupuncture [control]). All groups received 20 treatments, which included electrical stimulation, over a period of four weeks. The primary outcome was the number of days with a migraine experienced during weeks 5-8 after randomization. Our secondary outcomes included the frequency of migraine attack, migraine intensity and migrainespecific quality of life.Results: Compared with patients in the control group, patients in the acupuncture groups reported fewer days with a migraine during weeks 5-8, however the differences between treatments were not significant (p > 0.05). There was a significant reduction in the number of days with a migraine during weeks [13][14][15][16] was a significant, but not clinically relevant, benefit for almost all secondary outcomes in the three acupuncture groups compared with the control group. We found no relevant differences between the three acupuncture groups.Interpretation: Acupuncture tested appeared to have a clinically minor effect on migraine prophylaxis compared with sham acupuncture.

The effects of acupuncture as adjunctive treatment to antianginal therapies for patients with chronic stable angina are uncertain. OBJECTIVE To investigate the efficacy and safety of acupuncture as adjunctive therapy to antianginal therapies in reducing frequency of angina attacks in patients with chronic stable angina. DESIGN, SETTING, AND PARTICIPANTS In this 20-week randomized clinical trial conducted in outpatient and inpatient settings at 5 clinical centers in China from October 10, 2012, to September 19, 2015, 404 participants were randomly assigned to receive acupuncture on the acupoints on the disease-affected meridian (DAM), receive acupuncture on the acupoints on the nonaffected meridian (NAM), receive sham acupuncture (SA), and receive no acupuncture (wait list [WL] group). Participants were 35 to 80 years of age with chronic stable angina based on the criteria of the American College of Cardiology and the American Heart Association, with angina occurring at least twice weekly. Statistical analysis was conducted from December 1, 2015, to July 30, 2016. INTERVENTIONS All participants in the 4 groups received antianginal therapies as recommended by the guidelines. Participants in the DAM, NAM, and SA groups received acupuncture treatment 3 times weekly for 4 weeks for a total of 12 sessions. Participants in the WL group did not receive acupuncture during the 16-week study period. MAIN OUTCOMES AND MEASURES Participants used diaries to record angina attacks. The primary outcome was the change in frequency of angina attacks every 4 weeks from baseline to week 16. RESULTS A total of 398 participants (253 women and 145 men; mean [SD] age, 62.6 [9.7] years) were included in the intention-to-treat analyses. Baseline characteristics were comparable across the 4 groups. Mean changes in frequency of angina attacks differed significantly among the 4 groups at 16 weeks: a greater reduction of angina attacks was observed in the DAM group vs the NAM group (difference, 4.07; 95% CI, 2.43-5.71; P < .001), in the DAM group vs the SA group (difference, 5.18; 95% CI, 3.54-6.81; P < .001), and in the DAM group vs the WL group (difference, 5.63 attacks; 95% CI, 3.99-7.27; P < .001). CONCLUSIONS AND RELEVANCE Compared with acupuncture on the NAM, SA, or no acupuncture (WL), acupuncture on the DAM as adjunctive treatment to antianginal therapy showed superior benefits in alleviating angina.

SUMMARY BackgroundFunctional dyspepsia (FD) is a common disease without an established optimal treatment.

Objective.-To discuss the results of a multicenter randomized controlled trial of the efficacy of verum acupuncture in treating acute migraine attacks.Background.-Acupuncture has been used in China for centuries to treat migraine headache. Convincing evidence of its efficacy in alleviating pain, however, has been inadequate to date.Methods.-A total of 218 patients with migraine were recruited for the study; 180 met the inclusion criteria; 175 completed the callback process and were randomized into 3 groups. One group received verum acupuncture while subjects in the other 2 groups were treated with sham acupuncture. Each patient received 1 session of treatment and was observed over a period of 24 hours. The main outcome measure was the differences in visual analog scale (VAS) scores before treatment and 0.5, 1, 2, and 4 hours after treatment.Results.-Significant decreases in VAS scores from baseline were observed in the fourth hour after treatment when VAS was measured in the patients who received either verum acupuncture or sham acupunctures (P < .05). The VAS scores in the fourth hour after treatment decreased by a median of 1.0 cm, 0.5 cm, and 0.1 cm in the verum acupuncture group, sham acupuncture group 1, and sham acupuncture group 2, respectively. Similarly, there was a significant difference in the change in VAS scores from baseline in the second hour after treatment among the 3 groups (P = .006). Moreover, at the second hour after treatment, only patients treated with verum acupuncture showed significant decreases in VAS scores from baseline by a median of 0.7 cm (P < .001). Significant differences were observed in pain relief, relapse, or aggravation within 24 hours after treatment as well as in the general evaluations among the 3 groups (P < .05). Most patients in the acupuncture group experienced complete pain relief (40.7%) and did not experience recurrence or intensification of pain (79.6%).Conclusion.-Verum acupuncture treatment is more effective than sham acupuncture based on either Chinese or Western nonacupoints in reducing the discomfort of acute migraine. Verum acupuncture is also clearly effective in relieving pain and preventing migraine relapse or aggravation. These findings support the contention that there are specific physiological effects that distinguish genuine acupoints from nonacupoints.

Chronic atrophic gastritis (CAG) is a common gastrointestinal disease which has been considered as precancerous lesions of gastric carcinoma. Previously, electro-acupuncture stimulation has been shown to be effective in ameliorating symptoms of CAG. However the underlying mechanism of this beneficial treatment is yet to be established. In the present study, an integrated histopathological examination along with molecular biological assay, as well as 1H NMR analysis of multiple biological samples (urine, serum, stomach, cortex and medulla) were employed to systematically assess the pathology of CAG and therapeutic effect of electro-acupuncture stimulation at Sibai (ST 2), Liangmen (ST 21), and Zusanli (ST 36) acupoints located in the stomach meridian using a rat model of CAG. The current results showed that CAG caused comprehensive metabolic alterations including the TCA cycle, glycolysis, membrane metabolism and catabolism, gut microbiota-related metabolism. On the other hand, electro-acupuncture treatment was found able to normalize a number of CAG-induced metabolomics changes by alleviating membrane catabolism, restoring function of neurotransmitter in brain and partially reverse the CAG-induced perturbation in gut microbiota metabolism. These findings provided new insights into the biochemistry of CAG and mechanism of the therapeutic effect of electro-acupuncture stimulations.
