Electroacupuncture for patients with refractory functional dyspepsia: A randomized controlled trial.

BACKGROUND: To test the efficacy of electroacupuncture for patients with refractory functional dyspepsia (FD). METHODS: A 24-week, 2-arm, single-blind, randomized controlled trial was conducted at three hospitals in China. Patients with refractory FD were randomly assigned to receive 20 sessions of authentic or sham electroacupuncture in a treatment duration of 4 weeks. The primary outcome was complete absence of dyspeptic symptoms at 16 weeks after initiation of acupuncture (week 16). The secondary outcomes included adequate relief of dyspeptic symptoms, Leeds Dyspepsia Questionnaire (LDQ), Nepean Dyspepsia Index (NDI), and adverse events. Intention-to-treat analysis was performed. KEY RESULTS: Two hundred patients were included, of which 196 (98%) completed follow-up data at week 24. At week 16, 17 (17%) patients in the authentic electroacupuncture group vs 6 (6%) patients in the sham group achieved the primary outcome (P = .014). Sixty-two (62%) patients had adequate relief in the authentic electroacupuncture group, as compared to 22 (22%) in the sham group (P = .001). The scores of LDQ and NDI were significantly improved in both groups at week 16, and patients in the authentic electroacupuncture group have more improvements (LDQ, mean difference, -2.2, 95% confidence interval, -2.3 to -2.1, P < .001; NDI, -7.3, -10.5 to -4.2, P < .001). Results were similar for all the outcomes assessed at week 24. No serious adverse events were reported in both groups. CONCLUSION: Acupuncture efficaciously improves dyspeptic symptoms in patients with refractory FD.

[A preliminary discussion on the contents and value of Shi er mai (Twelve Channels) and Bie mai (Allo-channels), the medical bamboo slips unearthed from Han tomb in Laoguanshan of Chengdu].

The 52 medical bamboo slips entitled Si er ma (Twelve Channels) and Bie mai (Allo-channels) , unearthed from Han tomb in Laoguanshan, are the exclusive medical books concerning channels. Shi er mai is the first work bearing the term " heart dominating channel" , and the running pathways and manifestations of 12 channels. This book could be the major original sources of the 12-channel theories described in the Chapter of Jing mai (Channels) of Ling shu (Miraculous Pivot) . While Bie mai suggests the coexistence of the multi-channel systems at the time when the book was compiled and, together with the 12 "channel" , and 3 "branched collaterals" , these 2 books represent the original condition before the establishment of the mode of channel circulation in Ling shu, and is significant to explore the nature and origin of channel.

[A preliminary evaluation and discussion on the significance of the medical bamboo slips Ci shu (Needling Methods) unearthed from a Han tomb in the Mount. Laoguan, Chengdu].

The compilation of medical bamboo slips, Ci shu(Needling Methods), which was unearthed from a Han tomb in Mt. Laoguan, is a monograph dealing exclusively with the principles of clinical acupuncture manipulations with 40 acupuncture prescriptions, being the earliest unearthed work with documented standard methods of acupuncture manipulations and acupuncture prescriptions in China. The chapter Zhen fang (Acupuncture Prescriptions) is the earliest summary of standardized acupoint prescriptions up to now in China, which is of great significance to clinical practice directly derived from ancient clinical performance of acupuncture. The chapter Zhen fang of the book Ci shu is also one of the earliest ancient clinical reports archiving the acupoint. This may provide invaluable perspectives to the study of the conceptualization, origination, development, formation of theoretical system, and clinical application of acupoints.

Local and distant acupuncture points stimulation for chronic musculoskeletal pain: A systematic review on the comparative effects.

One in four people suffers from chronic musculoskeletal pain (CMP). Acupuncture points stimulation is increasingly used for pain relief for CMP. Commonly, a combination of local and distant points is used. However, the difference between the effects of local and distant point stimulation is unknown. This systematic review aimed to determine if there was a difference in effects between stimulating local and distant points, and the combination of both when compared with either alone. English and Chinese electronic databases were searched to identify randomized controlled trials, where local or distant points were stimulated in adults with CMP. Pain intensity was the primary outcome measure. Nineteen were included in the qualitative analysis and 15 in the meta-analysis. Local and distant point stimulation was more effective than their respective controls in pain reduction immediately after treatment. Three studies directly compared the stimulation of local and distant points and found no significant difference between the two. No studies compared combined local and distant point stimulation with either alone. Subgroup analyses showed that, local tender point stimulation was more effective than local acupuncture points. Local and distant point stimulation induces similar degree of acupuncture analgesia. The benefit of combining local and distant point stimulation is unknown. However, subgroup analyses suggested that local tender points could be important in the treatment of CMP for short-term pain relief.

Randomised clinical trial: an assessment of acupuncture on specific meridian or specific acupoint vs. sham acupuncture for treating functional dyspepsia.

BACKGROUND: Functional dyspepsia (FD) is a common disease without an established optimal treatment. AIM: To determine (i) the effect of acupuncture in relieving FD symptoms and improving life quality; (ii) the effect difference between acupoint and non-acupoint; and (iii) the effect difference among different acupoints. METHODS: A total of 712 eligible patients were included and randomly assigned to six groups (Group A: specific acupoints of the stomach meridian; Group B: non-specific acupoints of the stomach meridian; Group C: specific acupoints of alarm and transport points; Group D: specific acupoints of the gallbladder meridian; Group E: sham acupuncture of non-acupoints; and Group F: itopride). A treatment period of 4 weeks (continuous five sessions per week), and a follow-up period of 12 weeks were arranged. The outcomes were the (i) patients' response, (ii) symptoms improvement measured using the Symptom Index of Dyspepsia and (iii) quality-of-life improvement based on Nepean Dyspepsia Index. RESULTS: All groups had an improvement in dyspepsia symptoms and the QoL at the end of treatment, and the improvement was sustained for 4 weeks and 12 weeks. The overall response rate was significantly higher in acupuncture group A (70.69%), and lower in sham acupuncture group (34.75%), compared with itopride and other acupuncture groups. Similarly, the difference in symptoms and QoL improvement was significant between group A and the other acupuncture groups. CONCLUSIONS: Acupuncture is effective in the treatment of functional dyspepsia, and is superior to non-acupoint puncture. The benefit of acupuncture relies on acupoint specificity.
