Despite the availability of various non-surgical and pharmacological treatments, their effectiveness is often limited by temporary symptom relief and lack of disease-modifying properties. Platelet-rich plasma (PRP) has emerged as a promising biological therapy for KOA, with preclinical evidence suggesting its potential to promote cartilage repair and modulate inflammation. This systematic review and meta-analysis aims to comprehensively evaluate the efficacy and safety of PRP injections in the treatment of KOA.</p><p><strong>Methods: </strong>A systematic literature search was conducted from January 1, 2021, to December 31, 2024, encompassing major medical databases, clinical trial registries, and grey literature sources. Randomized controlled trials (RCTs) comparing PRP with other treatments for KOA were included based on predefined eligibility criteria. Data extraction and analysis were performed using various statistical software packages and machine learning models. A neural network model was constructed to predict PRP treatment outcomes by integrating multidimensional clinical features. Study quality was assessed using the Cochrane Risk of Bias Tool, and publication bias was evaluated through funnel plot analysis and Egger's test.</p><p><strong>Results: </strong>The meta-analysis included 28 RCTs with a total of 3246 KOA patients. PRP demonstrated comparable pain relief to hyaluronic acid (HA) but superior functional improvement, especially when combined with HA. Compared to corticosteroids, PRP showed no significant difference in efficacy as monotherapy but enhanced outcomes when used in combination. PRP also outperformed physical therapy and exercise therapy in both pain control and functional improvement. The optimal PRP concentration range was identified as 600-900 × 10⁹/L, with 3-5 injections at 7-14-day intervals yielding the best results.

T2D is a complex metabolic syndrome involving multiple cell types within multiple organs, such as the liver, muscle, adipose tissue, and pancreas. Because the adult human endocrine pancreas does not have regenerative capability, understanding of the pathogenesis of T2D is vital for working out successful strategies for the delay or arrest of disease development. Newly, ferroptosis, an iron-dependent, regulated cell death, has emerged as a significant promoter of the pathogenesis and development of T2D. Ferroptosis is distinguishable from apoptosis, autophagy, and necroptosis, and is characterized by the accumulation of iron, lipid peroxidation, and suppression of glutathione peroxidase 4 (GPX4). Ferroptosis in pancreatic β-cells results in the defective secretion of insulin. The labile iron pool (LIP), particularly Fe<sup>2</sup>⁺, enhances the formation of reactive oxygen species (ROS) during the Fenton reaction, thereby leading to ferroptosis. Recent empirical studies have revealed an exquisite regulatory interaction between ferroptosis and microRNAs (miRNAs), with the implication being that miRNAs play a central role in the regulation of ferroptosis during T2D. Two-way regulation of ferroptosis by miRNAs has been highlighted herein, with special focus on new insights and the speculation on the potential of using inhibition of ferroptosis as a strategy for treatment. Therapeutic approaches targeting ferroptosis include the use of ferroptosis inhibitors, such as Ferrostatin-1 and Deferoxamine, and miRNA-guided therapy that regulates iron homeostasis and lipid peroxidation. Such interventions may find practical applications in sustaining β-cell function and stimulating insulin secretion in diabetic patients. In conclusion, understanding the molecular mechanisms that regulate ferroptosis and identifying specific drugs targeting ferroptosis and associated miRNAs may unlock novel and effective therapies for individuals with T2D.</p>","PeriodicalId":11949,"journal":{"name":"European Journal of Medical Research","volume":"30 1","pages":"982"},"PeriodicalIF":3.4,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12529866/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145299360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
