ABSTRACT
BACKGROUND:
The main change of knee osteoarthritis is cartilaginous degeneration and secondary bone hyperplasia. The mechanism of these pathological changes is unclear, but some experiments have proved that the onset of knees osteoarthritis is closely related to inflammatory substances.OBJECTIVE:
To discuss the role of inflammatory substances in the pathogenesis of knee osteoarthritis.METHODS:
According to diagnostic criteria set by the American Colege of Rheumatology, we selected 60 knee osteoarthritis patients as experimental group, and another 60 patients undergoing the operative treatment of traumatic amputation or meniscus injury (except knee injury) as control group. After extracting synovial fluid samples from two groups, ELISA assay method was used to detect the levels of interleukin-1β, interleukin-6, interleukin-8, interleukin-10, tumor necrosis factor α, basic fibroblast growth factor, and osteopontin. The nitric oxide level in the synovial fluid was detected with nitric oxide detection kit. The content of lipid peroxidase was detected using TBA fluorescence method. RESULTS ANDCONCLUSION:
We found higher levels of interleukin-1β, interleukin-6, interleukin-8, interleukin-10, tumor necrosis factor α, basic fibroblast growth factor, osteopontin, nitric oxide, and lipid peroxidase in knee osteoarthritis patients, and these levels were positively correlated with knee osteoarthritis. These inflammatory substances are realy involved in the inflammation process of knees osteoarthritis.
