While increasing numbers of patients are seeking acupuncture treatment for depression in recent years, there is limited evidence of the antidepressant (AD) effectiveness of acupuncture. Given the unsatisfactory response rates of many Food and Drug Administration- approved ADs, research on acupuncture remains of potential value. Therefore, we sought to review the efficacy and safety of acupuncture treatment for depression in clinical applications. We conducted a PubMed search for publications through 2011. We assessed the adequacy of each report and abstracted information on reported effectiveness or efficacy of acupuncture as monotherapy for major depressive disorder (MDD) and as augmentation of ADs. We also examined adverse events associated with acupuncture, and evidence for acupuncture as a means of reducing side effects of ADs. Published data suggest that acupuncture, including manual-, electrical-, and laser-based, is a generally beneficial, well-tolerated, and safe monotherapy for depression. However, acupuncture augmentation in AD partial responders and nonresponders is not as well studied as monotherapy; and available studies have only investigated MDD, but not other depressive spectrum disorders. Manual acupuncture reduced side effects of ADs in MDD. We found no data on depressive recurrence rates after recovery with acupuncture treatment. Acupuncture is a potential effective monotherapy for depression, and a safe, well-tolerated augmentation in AD partial responders and nonresponders. However, the body of evidence based on well-designed studies is limited, and further investigation is called for.

Objective: Post-operative cognitive dysfunction (POCD) is a common post-surgical complication, which is associated with increased costs and extended hospital stays. Recently, interest in acupuncture as a potential therapy for POCD has grown. The objective of this meta-analysis was to assess the effectiveness of acupuncture for POCD. Methods: PubMed, Embase, CENTRAL, Medline, Web of Science, CNKI, Wanfang, and VIP databases were searched through March 2018. Randomized controlled trials (RCTs) in which patients with POCD treated with acupuncture (acupuncture group) were compared with those receiving a no treatment control were included. Meta-analyses were conducted using Review Manager 5.3. Results: Sixteen studies containing 1241 participants were included. POCD incidence in the acupuncture group was significantly lower than that in the control groups on the first (odds ratio (OR) = 0.32, 95% confidence interval (CI) = 0.23–0.45) and third (OR = 0.41, 95% CI = 0.30–0.56) post-operative days, with no statistically significant difference on the seventh day (OR = 0.58, 95% CI = 0.32–1.04). Acupuncture therapy also improved mini–mental state examination (MMSE) scores on the first (mean difference (MD) = 3.28, 95% CI = 2.79–3.77) and third (MD = 2.52, 95% CI = 2.18–2.87) post-operative days, with no effect on the seventh (MD = 0.14, 95% CI = –0.24 to 0.51). Visual analogue scale (VAS) scores on the first post-operative day were not impacted by acupuncture but were likely associated with post-operative nausea and vomiting on the seventh post-operative day. With respect to methodological quality, most RCTs were found to have an unclear risk of bias. Conclusion: Acupuncture may successfully treat/prevent POCD. However, the current evidence is limited and further research is needed.

Objective: To evaluate the efficacy/effectiveness of acupressure as an adjunct to standard procedures during labor and delivery, compared with standard procedures with/without sham acupressure, in randomized controlled trials (RCTs). Methods: Ten main databases were searched from their inception until 31 January 2018. Two reviewers independently extracted data concerning the effects of acupressure on pain intensity, labor duration, mode of delivery, use of medications and adverse events. A meta-analysis of these measures was performed using RevMan 5.3. Pooled standardized mean differences (SMDs) or odds ratios (ORs) for the above outcomes were estimated with a fixed or random effects model, according to the heterogeneity. Results: A total of 13 RCTs including 1586 enrolled patients met the eligibility criteria. Acupressure plus standard procedures (ASP) for labor management significantly reduced pain sensation, compared with sham acupressure plus standard procedures (SASP) and standard procedures (SP) alone. The analgesic effect of acupressure was immediate and persisted for at least 60 min (all p < 0.01). Compared with the untreated control groups, the acupressure group had a shorter duration of labor, especially the first stage of labor (SMD = −0.76, 95% confidence interval (CI) = −1.10 to −0.43; p < 0.001; I2 = 74%) and second stage of labor (SMD = −0.37, 95% CI = −0.59 to −0.18; p < 0.001; I2 = 0%). Data suggesting that acupressure reduced the Cesarean section rate was inconclusive. The use of pharmacologic agents (oxytocin and analgesics) did not differ between the ASP, SASP and SP groups. No adverse events were reported in this limited number of studies. Conclusion: Moderate evidence indicates that acupressure may have promising effects on labor pain and duration. However, high-quality trials to verify these findings are warranted.
