A meta-analysis of the efficacy and safety of traditional Chinese medicine formula Ganmai Dazao decoction for depression

Ethnopharmacological relevance Ganmai Dazao (GMDZ) decoction is a traditional Chinese herbal formula commonly used for the treatment of depression. The objective of this study was to assess the efficacy and safety of GMDZ, either alone or as co-therapy, for depression. Materials and methods We systematically searched key databases (9 Chinese and 7 English) up until May 2013 for randomized controlled trials (RCTs). The primary outcomes were effective rate and self-rated or clinician-rated severity of depression. The secondary outcome was the occurrence of adverse events. Methodological quality of the RCTs was assessed by the Cochranes risk of bias assessment. Results Ten RCTs were included. All were written in Chinese and the methodological quality was generally low. Pooled analysis of 5 studies which compared GMDZ with antidepressants showed that GMDZ was significantly more efficacious than antidepressants in effective rate (risk ratio: 1.14, 95% CI: 1.02 to 1.27, P=0.02, I2=0%), but comparable in Hamilton Depression Rating Scale (HDRS) score (mean difference: -2.10, 95% CI: -4.62 to -0.41, P=0.10, I 2=92%). With regard to the other 5 studies which compared GMDZ plus antidepressants with antidepressants alone, there was no significant difference in effective rate (risk ratio: 1.24, 95% CI: 0.99 to 1.55, P=0.07, I 2=93%), but the end-point HDRS score was significantly lower in GMDZ antidepressants combination (mean difference: -4.25, 95% CI: -6.50 to -2.00, P=0.0002, I2=96%). Adverse events were more common with antidepressants than GMDZ (rate ratio: 0.52, 95% CI: 0.32 to 0.82, P=0.005, I2=37%) and in antidepressants alone compared to GMDZ antidepressants combination (rate ratio: 0.23, 95% CI: 0.08 to 0.68, P=0.08, I2=0%). Conclusion The overall results suggest that GMDZ has few side effects and the potential as an antidepressant. Adding GMDZ to antidepressants reduces side effects and enhances efficacy of antidepressants. However, due to the small number of studies and their limitations, further studies with better methodological quality and more comprehensive safety assessment are needed to determine the benefits and risks of GMDZ in the treatment of depression. © 2014 Elsevier Ireland Ltd.link_to_subscribed_fulltex

Prescription of Chinese Herbal Medicine in Pattern-Based Traditional Chinese Medicine Treatment for Depression: A Systematic Review

Traditional Chinese medicine (TCM) treatments are often prescribed based on individuals’ pattern diagnoses. A systematic review of randomized controlled trials in Chinese and English literatures on TCM pattern-based treatment for depression has therefore been conducted. A total of 61 studies, 2504 subjects, and 27 TCM patterns were included. Due to the large variation of TCM pattern among participants, we only analyzed the top four commonly studied TCM patterns: liver qi depression, liver depression and spleen deficiency, dual deficiency of the heart, and spleen and liver depression and qi stagnation. We found that Xiaoyao decoction was the most frequently used herbal formula for the treatment of liver qi depression and liver depression with spleen deficiency, while Chaihu Shugan decoction was often used for liver depression and qi stagnation. Bai Shao (Paeonia lactiflora Pall.) and Chai Hu (Bupleurum chinense DC.) were commonly used across different TCM patterns regardless of the prescribed Chinese herbal formulas. The rationale underlying herb selection was seldom provided. Due to the limited number of studies on TCM pattern-based treatment of depression and their low methodological quality, we are unable to draw any conclusion regarding which herbal formulas have higher efficacy and which TCM patterns respond better to CHM

Efficacy of abdominal acupuncture for neck pain: A randomized controlled trial.

This study aims to provide evidence regarding the clinical efficacy of abdominal acupuncture for neck pain.This randomized, patient and assessor-blind, sham-controlled trial was conducted at a Chinese medicine center in Hong Kong between November 2014 and March 2016. A total of 154 eligible participants (age range, 18-65 years) with neck pain were randomly assigned to receive abdominal (n = 77) or non-penetrating sham abdominal (sham group; n = 77) acupuncture. Each participant was administered treatment over six sessions by Registered Chinese Medicine Practitioners, in accordance with a standardized protocol. The primary outcome was mean improvement in neck pain disability scores evaluated by the Northwick Park Neck Pain Questionnaire (NPQ). Secondary outcomes included intensity of neck pain and health-related quality-of-life measures. The outcomes were assessed at baseline and at 2 and 6 weeks from baseline. Patients in the abdominal acupuncture group received additional follow-up evaluation at 14 weeks from baseline. Outcomes were evaluated by intention-to-treat analysis.All participants provided informed consent for treatment and follow-up evaluation. Patients who received abdominal acupuncture exhibited greater improvement in NPQ scores than those who received sham treatment at both 2 and 6 weeks from baseline (intergroup mean differences, -5.75; 95% confidence interval [CI], -9.48 to -2.03; P = 0.008 and -8.65; 95% CI, -12.13 to -5.16; P < 0.001, respectively). The improvement in NPQ scores in the abdominal acupuncture group was even more significant at 14 weeks from baseline. Patients in the abdominal acupuncture group also exhibited significantly greater improvements in intensity of neck pain and a few quality-of-life measures than those in the sham abdominal acupuncture group, without any serious adverse events.These findings suggest that abdominal acupuncture is an effective alternative treatment for neck pain.Chinese Clinical Trial Registry ChiCTR-TRC-14004932

Acupuncture for post-stroke depression: a systematic review and network meta-analysis

Abstract Background Patients with post-stroke depression (PSD) usually experience anxiety, hopelessness, and insomnia, which have a negative impact on their daily activities and post-stroke rehabilitation. Acupuncture (AC), as a minimally invasive technique, has become a popular choice for improving depression symptoms. However, it is still unclear which therapy is associated with the best outcomes for PSD. In this review, we aimed to explore the impact of AC in alleviating symptoms of PSD and to evaluate the difference in effectiveness between AC combined with pharmacotherapies and various non-pharmacotherapies. Methods Six databases and three clinical trials registration platforms were searched from inception to March 2023. Randomized clinical trial comparing needle-based AC with pharmacotherapy, and other non-pharmacotherapy or invalid group were included. Two independent reviewers identified eligible studies, and collected data using a pre-made form. A Bayesian network meta-analysis was conducted to assess and compare different techniques using RStudio 3.6.0 with the package ‘GEMTC’ V.0.8.1. The primary outcome was the efficacy for PSD assessed by scales measuring depressive symptoms. The secondary outcomes were effectiveness for neurological function and the quality of life. The ranking probabilities for all treatment interventions was performed using the Surface Under the Cumulative Ranking curve (SUCRA). The risk of bias was assessed by using the Revised Cochrane Risk of Bias tool 2. Results Sixty-two studies, involving 5308 participants published from 2003 to 2022, were included. The results showed that compared with western medicine (WM) (defined as pharmacotherapy for PSD), AC alone or with repetitive transcranial magnetic stimulation (RTMS), Traditional Chinese medicine (TCM) alone or with WM, were superior for alleviating depression symptoms. Compared to Usual Care, AC alone or plus other therapies could significantly decrease scores on the Hamilton Depression Rating scale. According to result of SUCRA, AC plus RTMS had the highest probability of improving depressive symptoms with a probability of 49.43%. Conclusions The results of this study indicate that AC alone or combined with other therapies appears to be effective in improving depression symptoms of stroke survivors. Moreover, in comparison to WM, AC alone or plus RTMS, TCM, TCM with WM, or WM, were more effective in improving depression symptoms of PSD. Also, AC with RTMS seems to be the most effective with the highest probability. Registration This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database in November 2020 and updated in July 2021.
