ABSTRACT
Objective To study the correlation between the expression levels of four inflammatory factors (interleukin [IL]-1β, IL-6, IL-8 and tumor necrosis factor α [TNF-α]) in knee joint fluid and the related histopathology. Methods Before the joint surgery, the knee joint fluid was extracted from 31 patients. The expression levels of IL-1β, IL-6, IL-8 and TNF-α in knee joint fluid were examined by cytometric bead array, and the pathological feature of synovial tissues was analyzed. According to the histopathological diagnosis, the patients were divided into osteoarthritis (OA), revision after prosthesis replacement (RPR), pigmented villonodular synovitis (PVNS) and rheumatoid arthritis (RA) groups. According to the content of hemosiderin in the synovial tissue, they were divided into hemosiderin deposition group and non-hemosiderin deposition group. According to the infiltration of inflammatory cells in synovial tissue, they were divided into inflammatory cell infiltration group and noninflammatory cell infiltration group. According to the color of knee joint fluid, they were divided into blood joint fluid group and non-blood joint fluid group. Results There were nine male and 22 female patients with an average age of (63.60±9.19) years, including 12 left knees and 19 right knees. There were 18 cases with OA, five with RPR, five with PVNS and three with RA. The levels of four inflammatory factors in the knee joint fluid of OA group were the lowest, which were significantly different from the other three groups (all P0.05). The level of IL-6 in knee joint fluid of RA group was significantly higher than that of PVNS group, but significantly lower than that of RPR group, and the differences between the three groups were significant (all P0.05). Conclusion IL-1β, IL-6, IL-8 and TNF-α are expressed in various joint diseases and the expressions are related to their pathological features, which can help further understand the pathogenesis and development of some joint diseases, so as to provide a reference for clinical diagnosis, treatment and basic research.
