BACKGROUND:Osteoarthritis is a chronic degenerative disease of skeletal muscle,and the incidence of osteoarthritis is increasing yearly,but its pathogenesis is not clear.The commonly used drugs for osteoarthritis include non-steroidal anti-inflammatory drugs and glucocorticoid.Adverse drug reactions to these drugs can reduce patient compliance and ultimately affect the efficacy of treatment.Active ingredients in Chinese medicine are closely scrutinized for their safety and other characteristics. OBJECTIVE:Through reviewing the research progress in the effect of active ingredients of traditional Chinese medicine on osteoarthritis-related signaling pathways,to provide ideas and theoretical basis for the research,development,and application of new drugs in the prevention and treatment of osteoarthritis. METHODS:CNKI,WanFang,VIP,PubMed,and GeenMedical were searched for relevant literature in the last 10 years.The key words were"OA,osteoarthritis,traditional Chinese medicine,active ingredients of traditional Chinese medicine,chondrocyte,inflammation,signal pathways,mechanism"in Chinese and English.We excluded the irrelevant repetitive and older literature,and finally included 63 articles for further review. RESULTS AND CONCLUSION:The active ingredients of traditional Chinese medicine regulate the levels of inflammatory factors,promote the proliferation and differentiation of chondrocytes,regulate the apoptosis of chondrocytes,and delay the degeneration of chondrocytes through Wnt/β-catenin,NK-ΚB,P38 MAPK,PI3K/AKT,JAK2/STAT3 and other signaling pathways,thus slowing the progression of osteoarthritis.

Since 2010, the incidence of severe fever with thrombocytopenia syndrome (SFTS) has been increased. Owing the progress in diagnosis and treatment, the overall mortality of SFTS in China has decreased, while the mortality in critical SFTS patients is still high. In order to provide guidance and working procedures for clinicians to diagnose and treat critical SFTS, the National Medical Center for Major Public Health Events invited experts to discuss and formulate this consensus based on their experience and up-to-date knowledge on SFTS.
