Efficacy and safety of electroacupuncture for benign prostatic hyperplasia: A systematic review and meta-analysis.

BACKGROUND: This study aimed to evaluate the efficacy and safety of electroacupuncture (EA) in the treatment of benign prostatic hyperplasia. METHODS: Seven databases were searched from the inception of each database to March 31, 2023, including PubMed, Web of Science, Cochrane, Embase, China National Knowledge Infrastructure, Wanfang, and China Biology Medicine. The modified Jadad scale was used to assess literature quality, and literature inclusion and exclusion were conducted in strict accordance with the criteria of a score of ≥4. The risk of bias was evaluated using the Cochrane risk of bias tool. The pooled effect size of the binary data was measured by odds ratio (OR) and 95% confidence interval (CI), and the pooled effect size of the continuous data was presented as weighted mean difference (WMD) and 95% CI. If I² was larger than 50%, a random effects model was adopted, and otherwise, a fixed effects model was used. Additionally, publication bias assessment and sensitivity analysis were conducted. RESULTS: A total of 325 records were retrieved, and finally 9 randomized controlled trial studies were included, involving 1045 patients. Meta-analysis revealed that the EA group had better improvement than the control group in terms of clinical effective rate (odds ratio = 3.92, 95% CI = 2.38 to 6.47, I²â€…= 0%, P < .001), International Prostate Symptom Score (WMD = -4.99, 95% CI = -6.15 to -3.84, I²â€…= 76.9%, P < .001), maximum urinary flow rate (WMD = -4.99, 95% CI = -6.15 to -3.84, I²â€…= 87.4%, P < .001), and post-void residual volume (WMD = -17.12, 95% CI = -29.49 to -4.75, I²â€…= 89.1%, P < .01). There was no statistical significance in prostate volume and adverse events between the EA group and the control group (P > .05). CONCLUSION: EA is effective in the treatment of benign prostatic hyperplasia with acceptable overall safety.

Acupuncture for post-stroke spasticity: An overview of systematic reviews.

BACKGROUND: Post-stroke spasticity (PSS) is the most common complication of stroke. Acupuncture is widely used in clinical practice for the treatment of PSS, and is therefore considered a common complementary treatment. Several systematic reviews (SRs) and meta-analyses (MAs) have demonstrated the efficacy and safety of acupuncture in the treatment of PSS; however, the quality of evidence of these studies has not been adequately assessed. OBJECTIVE: To evaluate and summarize the SRs/MAs and inform future research and clinical practice on the efficacy and safety of acupuncture for PSS. DATA SOURCES AND EXTRACION: The following databases were searched from their dates of inception to March 26, 2023: PubMed, Embase, The Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Wanfang Database, SinoMed, and Chinese Science and Technology Periodical Database (VIP), and grey literature were manually searched. Two reviewers independently completed literature retrieval, screening, and data extraction. REVIEW APPRAISAL: Systematic evaluation tools to Assess Systematic Reviews (AMSTAR) 2, Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020 Checklist), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system were used to systematically evaluate the methodological, reporting, and evidence quality of the SRs/MAs. RESULTS: Overall, 226 papers were examined, and after careful consideration, 10 SRs/MAs were deemed eligible for inclusion. The AMSTAR 2 assessment revealed that one SR/MA had medium, one study had low, and the remaining eight studies had critically low methodological qualities. Additionally, four SRs/MAs completed more than 60 % of the PRISMA 2020 checklist. The GRADE system indicated that six outcomes were medium, 26 outcomes were low, and 24 outcomes were critically low. CONCLUSION: Based on the evidence, acupuncture may be a promising complementary treatment to improve post-stroke spasticity and quality of life. Further high-quality RCTs are needed in future studies to support the broader application of acupuncture for the treatment of PSS.

Corticospinal tract: a new hope for the treatment of post-stroke spasticity.

Stroke is the third leading cause of death and disability worldwide. Post-stroke spasticity (PSS) is the most common complication of stroke but represents only one of the many manifestations of upper motor neuron syndrome. As an upper motor neuron, the corticospinal tract (CST) is the only direct descending motor pathway that innervates the spinal motor neurons and is closely related to the recovery of limb function in patients with PSS. Therefore, promoting axonal remodeling in the CST may help identify new therapeutic strategies for PSS. In this review, we outline the pathological mechanisms of PSS, specifically their relationship with CST, and therapeutic strategies for axonal regeneration of the CST after stroke. We found it to be closely associated with astroglial scarring produced by astrocyte activation and its secretion of neurotrophic factors, mainly after the onset of cerebral ischemia. We hope that this review offers insight into the relationship between CST and PSS and provides a basis for further studies.
