Aquaporins ( AQPs ) act as an important channel for body water crossing the cell membrane, and are closely related to the balance of water metabolism and water reserves. Recent studies have found that there are signiifcant differences in the expressions of AQPs in arthritis joints and normal joints. The expressions of AQP1, AQP3 and AQP9 in the patients with rheumatoid arthritis and osteoarthritis are all signiifcantly increased, which are enhanced with the occurrence of lesions. The expressions of AQP4 are higher in the patients with gouty arthritis and osteoarthritis than in the patients with normal joints, which can reflect the severity of articular diseases. After medication, the expressions of AQPs are remarkably reduced, and the arthritis symptoms are improved. It points out that a special intimate relationship exists between the upregulation of the expressions of AQPs in arthritis joints and the occurrence and development of pathological changes. With AQPs as therapeutic targets, the cell membrane pe
