Effect of acupuncture at 3-points for intelligence on vascular dementia Protocol for a systematic review and meta-analysis of randomized controlled trials

Abstract

Background: Vascular dementia (VD) is a commonly-seen disease in the elderly. What is more, “Acupuncture at 3-points for intelligence” is one of the most important components of “Jin’s three-needle therapy” created by Rui Jin, a professor of Guangzhou University of Chinese Medicine, which can be used in the VD patients. In this article, researchers will assess the clinical efficacy and safety of acupuncture at 3-points for intelligence in the treatment of VD. Methods: A systematic literature search for articles up to September 2018 will be conducted using 9 databases: PubMed, Cochrane Library, Embase, CNKI, CBM, VIP, Wanfang database, OASIS, and CiNii. Inclusion criteria are randomized controlled trials (RCTs) of acupuncture at 3-points for intelligence on treating VD. The primary outcome measures will be scores reflecting the neurological function of participants based on common medical scales. Hemorheology indexes, homocysteine (Hcy), acetylcholine (Ach), nitric oxide (NO), and adverse events will also be assessed. Stata V.13.0 software will be used for data synthesis, sensitivity analysis, meta-regression, subgroup analysis, and risk of bias assessment. A funnel plot will be developed to evaluate reporting bias. Egger and Begg tests will be further performed to conduct quantitative evaluation of publication bias and to evaluate the symmetry of funnel plot. We will use the Grading of Recommendations Assessment, Development, and Evaluation system to assess the quality of evidence. Results: The results of this systematic review and meta-analysis will be published in a peer-reviewed journal. Conclusion: Our study will provide the evidence for the clinical efficacy and safety of acupuncture at 3-points for intelligence in the treatment of VD.
