“…Hematoxylin-eosin (HE) was used to stain the renal histopathological section, and the microscope (×400) was used to observe the structural changes of renal tubules and glomerulus; the peroxidase method was used to detect the renal function indexes such as uric acid (UA), creatinine (Cre) and urea nitrogen (BUN); enzyme-linked immunosorbent assay (ELISA) method was used to determine the contents of interleukin-1β (IL-1β) in serum and kidney tissues; Western blot was used to detect the expressions of Caspase-1, IL-1β and glucose transporter 9 (GLUT-9) in the kidney tissues.Results① Pathological examination results: there was not obvious pathological changes were observed in the kidney tissues of the Control group; in the Model group, the renal tissue capsule was incomplete, the glomerulus was deformed and atrophic, and the renal tubules were disordered; in the Exercise group, the number of inflammatory cell infiltration was significantly decreased, the renal tubular structure was relatively intact, and the pathological changes such as cytoplasmic vacuolation of renal tubular epithelial cells were significantly decreased. ② UA, Cre and BUN content of serum: compared with the Control group, UA, BUN and Cre content in serum of the Model group and Exercise group was significantly increased (<italic>P</italic>&lt;0.05); compared with the Model group, UA, BUN and Cre content in serum of the Exercise group were significantly decreased (<italic>P</italic>&lt;0.05). ③ Serum and kidney IL-1β content: compared with the Control group, the expression of IL-1β in serum and kidney of the Model group and the Exercise group were significantly increased (<italic>P</italic>&lt;0.05); compared with the Model group, the expression of IL-1β in serum and kidney of the Exercise group was significantly decreased (<italic>P</italic>&lt;0.05). ④ Expressions of Caspase-1, IL-1β and GLUT-9 protein: compared with the Control group, the expressions of Caspase-1, IL-1β and GLUT-9 protein in kidney tissues of the Model group and the Exercise group were significantly increased (<italic>P</italic>&lt;0.05); compared with the Model group, the expressions of Caspase-1, IL-1β, and GLUT-9 protein in kidney tissues of the Exercise group were significantly decreased (<italic>P</italic>&lt;0.05).ConclusionAerobic treadmill exercise can effectively reduce the level of uric acid and inflammatory response of hyperuricemia rats, and improve renal function, which may be related to the regulation of GLUT-9 protein expression.…”
