OBJECTIVE: To compare the effects of filiform needling, electroacupuncture (EA) and moxibustion on articular cartilage morphology and nuclear transcription factor-κB (NF-κB) p65/ Nod-like receptor protein 3 (NLRP3) pathway in rats with knee osteoarthritis (KOA). METHODS: Wistar rats were randomly divided into blank control， model, filiform needling, EA and moxibustion groups, with 8 rats in each group. The KOA model was established by injecting sodium iodoacetate into the right knee cavity. Filiform needling, EA and moxibustion groups were treated with the right side of "Dubi" (ST35) and "Neixiyan" (EX-LE5), and were given filiform needling, EA and mild moxibustion therapies for 15 min respectively, once every other day, for a total of 4 weeks. The diameter of the right knee joint was observed. The ultrastructure of knee chondrocytes was observed by transmission electron microscope. The contents of serum tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-18 were determined by ELISA. The expression levels of NF-κB p65, NLRP3, apoptosis-related speckle like protein (ASC) and TNF-α in knee cartilage were dectected by Western blot. RESULTS: <0.05) in moxibustion group. CONCLUSION: Filiform needling, EA and moxibustion can all reduce the formation of knee osteophytosis in KOA rats, alleviate joint cavity narrowing, improve the ultrastructure of articular cartilage, reduce the level of inflammatory factors, regulate the NF-κB p65/NLRP3 pathway. Moxibustion has the most obv...
