Osteoarthritis （OA）， rheumatoid arthritis （RA）， gouty arthritis （GA）， and intervertebral disc degeneration （IVDD） are the most common bone and joint-related diseases in clinical practice. They can all affect related joints， leading to joint pain， swelling， dysfunction， and other symptoms. The difference is that OA is mainly caused by joint wear and age-related degradation and is manifested as joint pain， stiffness， and limited movement. RA is an autoimmune disease， manifested as joint pain， swelling， morning stiffness， and systemic symptoms. GA is caused by abnormal uric acid metabolism， manifested as acute arthritis， and IVDD is caused by intervertebral disc degeneration. Studies have shown that the mechanism of the occurrence and development of these bone and joint diseases is extremely complex. Pyroptosis is closely related to these bone and joint-related diseases by participating in bone and joint inflammation， cartilage metabolism imbalance， extracellular matrix degradation， and pathological damage of bone and joint. Inhibition of bone and joint-related pyroptosis will effectively prevent and treat bone and joint-related diseases. At the same time， many studies have confirmed that traditional Chinese medicine （TCM） has a prominent curative effect and obvious advantages in the prevention and treatment of bone and joint-related diseases. TCM can reduce the inflammatory reaction of bone and joints， improve the pathological damage of bone and joint diseases， and relieve bone and joint pain by inhibiting pyroptosis. Therefore， this article aims to briefly explain the relationship between pyroptosis and the occurrence and development of bone and joint-related diseases and summarize the latest research reports on the intervention of pyroptosis in the treatment of bone and joint-related diseases by TCM monomers， TCM extracts， and TCM compounds. It offers new ideas for the in-depth study of the pathogenesis and drug treatment of bone and joint diseases and provides a basis for the clinical use of TCM to prevent and treat bone and joint diseases.

【Objective】 To study the effects of different storage temperature and different storage time on the activity of key growth factors in platelet-rich plasma(PRP), and to provide a theoretical basis for maximize the role of PRP in clinical treatment. 【Methods】 PRP was collected by blood cell isolation and apheresis, stored at 22℃ and -80℃, respectively. VEGF, TGF-β and PDGF were detected by ELISA. The content of growth factors in PRP was detected when stored at 22℃for 1, 3 and 5 days, and the growth factors content of PRP stored at 22℃ for 3 days was detected after thrombin activation for 0.5, 1 and 1.5 hours. The content of growth factor in frozen PRP (stored at -80℃ for 30 days after initial 3-days storage at 22℃ ) and fresh PRP (stored at 22℃ for 3 days) was compared. The growth factor content in PRP frozen at - 80℃ for 30, 60 and 180 days, and the growth factor content in PRP frozen at -80℃ for 180 days after repeated freeze-thaw for 1, 2, 3, 5 and 10 times were detected. 【Results】 The growth factor content of apheresis PRP was significantly higher than that of platelet-poor plasma. No statistical difference was noticed in VEGF, TGF-β and PDGF content in PRP at 1, 3 and 5 days stored at 22℃; no statistical difference was noticed in VEGF, TGF-β and PDGF content in PRP stored at 22℃ for 3 days after thrombin activation for 0.5, 1 and 1.5 hours. There was no statistically significant difference in growth factor content between PRP stored at 22℃ for 3 days versus frozen at -80℃ for 30 days after initial 3-days storage at 22℃. No statistical difference was found in VEGF, TGF-β and PDGF contents in frozen PRP repeatedly frozen and thawed for 1 to 10 times. 【Conclusion】 Apheresis PRP can release a large amount of growth factors after activation. Fresh PRP stored at 22℃ for 5 days or frozen at -80℃ for 180 days has no impact on the content of growth factors, and frozen PRP at -80℃ can achieve long-term, effective and safe preservation, which is conducive to multiple use of PRP in treatment.
