Study on the Protective Effect of Platelet-Rich Plasma Combined with Injection of Pain Points Around Knee Joint on Knee Osteoarthritis and its Molecular Mechanism.
Objective: Previous studies showed the PRP have the therapeutic effects for KOA, but the more detail roles remained unclear and therefore this study was carried on to explore the deeper mechanisms for PRP.
Methods: NRS and WOMAC scores were used to evaluate the clinical efficacy before surgery, 1 month and 6 months after surgery, and the postoperative joint structure changes (n = 24). Examination of pathology of the femoral condyle plate in rats using HE staining (n = 6); Angiogenesis experiments were used to investigate the effect of different groups of cell culture supernatants on the tubular structure formation capacity of HUVECs (n = 3). Observe the proliferation of chondrocytes using clonal formation experiments (n = 3). Western blot was used to analyze the PI3K/AKT signaling pathway and the expression of exosome-secretion-related proteins (n = 3).
Results: In clinical studies, PRP can reduce patients' NRS and WOMAC scores and alleviate the progression of knee arthritis; In rat experiments, PRP reduced damage from knee arthritis and lowered Mankin's score. PRP improves tubular formation of HUVECs and the proliferation capacity of chondrocytes. Compared with the blank control group, the protein expression levels of PI3K, AKT, mTOR, P27, and cyclinD1 in the PRP group were increased. Compared with the PRP group, the protein expression levels of PI3K, AKT, mTOR, P27, and cyclinD1 in the PRP+Axitinib group supplemented with VEGFRs inhibitor and PI3K inhibitor group were significantly decreased. The effect of the LY294002 +PRP group was better than that of the above groups. Macrophage-derived exosomes activate HIF-1a and COX-2 in endothelial cells to promote chondrocyte repair of KOA.
Conclusion: PRP can promote chondrocytes proliferation and repair by activating the PI3K/AKT signaling pathway, thereby exerting anti-OA effects. It provides new targets and methods for the clinical treatment of OA.
期刊介绍:
Launched in 1995, Alternative Therapies in Health and Medicine has a mission to promote the art and science of integrative medicine and a responsibility to improve public health. We strive to maintain the highest standards of ethical medical journalism independent of special interests that is timely, accurate, and a pleasure to read. We publish original, peer-reviewed scientific articles that provide health care providers with continuing education to promote health, prevent illness, and treat disease. Alternative Therapies in Health and Medicine was the first journal in this field to be indexed in the National Library of Medicine. In 2006, 2007, and 2008, ATHM had the highest impact factor ranking of any independently published peer-reviewed CAM journal in the United States—meaning that its research articles were cited more frequently than any other journal’s in the field.
Alternative Therapies in Health and Medicine does not endorse any particular system or method but promotes the evaluation and appropriate use of all effective therapeutic approaches. Each issue contains a variety of disciplined inquiry methods, from case reports to original scientific research to systematic reviews. The editors encourage the integration of evidence-based emerging therapies with conventional medical practices by licensed health care providers in a way that promotes a comprehensive approach to health care that is focused on wellness, prevention, and healing. Alternative Therapies in Health and Medicine hopes to inform all licensed health care practitioners about developments in fields other than their own and to foster an ongoing debate about the scientific, clinical, historical, legal, political, and cultural issues that affect all of health care.
