This meta-analysis and systematic review aimed to evaluate the efficacy of electroacupuncture and explore its potential mechanisms in animal models of ischemic stroke. The PubMed, EMBASE, Web of Science, CENTRAL, and CINAHL databases were comprehensively searched up to May 1, 2024. This review included articles on preclinical investigations of the efficacy and mechanisms of electroacupuncture in treating ischemic stroke. Data from 70 eligible studies were analyzed in Stata 18.0, using a random-effects model to calculate the standardized mean difference (Hedge's g). The risk of bias was assessed using RevMan 5.4 software, and the quality of evidence was rated according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. Subgroup analyses were conducted to test the consistency of the results and sensitivity analyses were used to assess their robustness. The quality assessment revealed that most studies adequately handled incomplete data and selective reporting. However, several methodological limitations were identified: only 4 studies demonstrated a low risk of allocation concealment, 26 achieved a low risk of outcome assessment bias, and 9 had a high risk of randomization bias. Additionally, there was an unclear risk regarding participant blinding and other methodological aspects. The GRADE assessment rated 12 outcomes as moderate quality and 6 as low quality. The mechanisms of electroacupuncture treatment for ischemic stroke can be categorized as five primary pathways: (1) Electroacupuncture significantly reduced infarct volume and apoptotic cell death ( P < 0.01) in ischemic stroke models; (2) electroacupuncture significantly decreased the levels of pro-inflammatory factors ( P < 0.01) while increasing the levels of anti-inflammatory factors ( P = 0.02); (3) electroacupuncture reduced the levels of oxidative stress indicators ( P < 0.01) and enhanced the expression of antioxidant enzymes ( P < 0.01); (4) electroacupuncture significantly promoted nerve regeneration ( P < 0.01); and (5) electroacupuncture influenced blood flow remodeling ( P < 0.01) and angiogenesis ( P < 0.01). Subgroup analyses indicated that electroacupuncture was most effective in the transient middle cerebral artery occlusion model ( P < 0.01) and in post-middle cerebral artery occlusion intervention ( P < 0.01). Dispersive waves were found to outperform continuous waves with respect to neuroprotection and anti-inflammatory effects ( P < 0.01), while scalp acupoints demonstrated greater efficacy than body acupoints ( P < 0.01). The heterogeneity among the included studies was minimal, and sensitivity analyses indicated stable results. Their methodological quality was generally satisfactory.

Studies have shown that the optic nerve crush model and glaucoma model are commonly used to study retinal ganglion cell injury. While these models differ in their mechanisms, both ultimately result in retinal ganglion cell injury. With advancements in high-throughput technologies, techniques such as microarray analysis, RNA sequencing, and single-cell RNA sequencing have been widely applied to characterize the transcriptomic profiles of retinal ganglion cell injury, revealing underlying molecular mechanisms. This review focuses on optic nerve crush and glaucoma models, elucidating the mechanisms of optic nerve injury and neuron degeneration induced by glaucoma through single-cell transcriptomics, transcriptome analysis, and chip analysis. Research using the optic nerve crush model has shown that different retinal ganglion cell subtypes exhibit varying survival and regenerative capacities following injury. Single-cell RNA sequencing has identified multiple genes associated with retinal ganglion cell protection and regeneration, such as Gal , Ucn , and Anxa2 . In glaucoma models, high-throughput sequencing has revealed transcriptomic changes in retinal ganglion cells under elevated intraocular pressure, identifying genes related to immune response, oxidative stress, and apoptosis. These genes are significantly upregulated early after optic nerve injury and may play key roles in neuroprotection and axon regeneration. Additionally, CRISPR-Cas9 screening and ATAC-seq analysis have identified key transcription factors that regulate retinal ganglion cell survival and axon regeneration, offering new potential targets for neurorepair strategies in glaucoma. In summary, single-cell transcriptomic technologies provide unprecedented insights into the molecular mechanisms underlying optic nerve injury, aiding in the identification of novel therapeutic targets. Future researchers should integrate advanced single-cell sequencing with multi-omics approaches to investigate cell-specific responses in retinal ganglion cell injury and regeneration. Furthermore, computational models and systems biology methods could help predict molecular pathways interactions, providing valuable guidance for clinical research on optic nerve regeneration and repair.</p>","PeriodicalId":19113,"journal":{"name":"Neural Regeneration Research","volume":" ","pages":"989-999"},"PeriodicalIF":6.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12296432/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144002704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, chronic cerebral hypoperfusion is an important factor influencing the onset and progression of vascular dementia. The myelin sheath is a critical component of white matter, and damage and repair of the white matter are closely linked to myelin sheath integrity. This article reviews the role of microglia in vascular dementia, focusing on their effects on myelin sheaths and the potential therapeutic implications. The findings suggest that ischemia and hypoxia cause disruption of the blood-brain barrier and activate microglia, which may worsen blood-brain barrier damage through the release of matrix-degrading enzymes. Microglia-mediated metabolic reprogramming is recognized as an important driver of inflammation. Damage to the blood-brain barrier and subsequent inflammation can lead to myelin injury and accelerate the progression of vascular dementia. Early activation of microglia is a protective response that contributes to the maintenance of blood-brain barrier integrity through sensing, debris-clearing, and defensive mechanisms. However, prolonged activation can trigger a shift in microglia toward the pro-inflammatory M1 phenotype, resulting in myelin damage and cognitive impairment. Triggering receptor expressed on myeloid cells 2 and triggering receptor expressed on myeloid cells 1 have been identified as potential biomarkers for vascular dementia, as both are closely linked to cognitive decline. Although effective clinical treatments for myelin damage in the central nervous system are currently lacking, researchers are actively working to develop targeted therapies. Several drugs, including nimodipine, dopaminergic agents, simvastatin, biotin, and quetiapine, have been evaluated for clinical use in treating microglial and myelin damage. Future research will face challenges in developing targeted therapeutic strategies for vascular dementia, requiring further investigation into the timing, duration, and specific mechanisms of microglial activation, as well as the exploration of new drug combinations and additional therapeutic targets.</p>","PeriodicalId":19113,"journal":{"name":"Neural Regeneration Research","volume":" ","pages":"1000-1012"},"PeriodicalIF":6.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12296411/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143720788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review systematically analyzes the current understanding of the bidirectional relationship between blood-brain barrier disruption and neuroinflammation in traumatic brain injury, along with emerging combination therapeutic strategies. Literature review indicates that blood-brain barrier disruption and neuroinflammatory responses are key pathological features following traumatic brain injury. In the acute phase after traumatic brain injury, the pathological characteristics include primary blood-brain barrier disruption and the activation of inflammatory cascades. In the subacute phase, the pathological features are characterized by repair mechanisms and inflammatory modulation. In the chronic phase, the pathological features show persistent low-grade inflammation and incomplete recovery of the blood-brain barrier. Various physiological changes, such as structural alterations of the blood-brain barrier, inflammatory cascades, and extracellular matrix remodeling, interact with each other and are influenced by genetic, age, sex, and environmental factors. The dynamic balance between blood-brain barrier permeability and neuroinflammation is regulated by hormones, particularly sex hormones and stress-related hormones. Additionally, the role of gastrointestinal hormones is receiving increasing attention. Current treatment strategies for traumatic brain injury include various methods such as conventional drug combinations, multimodality neuromonitoring, hyperbaric oxygen therapy, and non-invasive brain stimulation. Artificial intelligence also shows potential in treatment decision-making and personalized therapy. Emerging sequential combination strategies and precision medicine approaches can help improve treatment outcomes; however, challenges remain, such as inadequate research on the mechanisms of the chronic phase traumatic brain injury and difficulties with technology integration. Future research on traumatic brain injury should focus on personalized treatment strategies, the standardization of techniques, cost-effectiveness evaluations, and addressing the needs of patients with comorbidities.
