Effect and Mechanism of Massage Manipulation on Rats with Skeletal Muscle Overuse Injury Based on Wnt/β-catenin Signaling Pathway
Published 2024-12-01“…Compared with the model group, the time to pass the balance beam and the number of paw slips in the intervention group decreased significantly after intervention, and the differences were statistically significant (<italic>P</italic><0.05). (2) Histopathological changes in gastrocnemius muscle tissue: the model group showed a large number of cracks within the muscle cells and broken myofibrils in the gastrocnemius muscle; compared with the model group, the intervention group had a reduced degree of muscle tissue damage, and the muscle fibers were in regular morphology and arranged in order. (3) Ultrastructural changes in gastrocnemius muscle tissue: the local myofibril bundles in the model group were broken and dissolved, and a small amount of Z-line structure was dissolved and blurred. …”

Effect and Mechanism of Action of Pushing Method on Rats with Skeletal Muscle Overuse Injury based on Wnt/β-catenin Signaling Pathway
Published 2024-01-01“…Catenin protein expression levels.Results(1) Comparison of motor function:compared with the blank group, the time of passing through the balance beam and the number of times of sliding paw were significantly increased in the model group and intervention group after intervention, and the difference was statistically significant (<italic>P</italic><0.05); compared with the model group, the time of passing through the paw and the number of times of sliding paw were significantly decreased in the intervention group after intervention, and the difference was statistically significant (<italic>P</italic><0.05). (2) Gastrocnemius muscle histopathological changes:the model group can be seen in the gastrocnemius muscle a large number of myocytes can be seen within the cracks, myogenic fibers fracture; compared with the model group, the degree of damage to the gastrocnemius muscle tissues in the intervention group to reduce the degree of damage, can be seen in the form of myofibers is regular, neatly arranged. (3) Ultrastructural changes in gastrocnemius muscle tissue:local myogenic fiber bundles were broken and dissolved, and a small amount of Z-line structure was dissolved and blurred; compared with the model group, the gastrocnemius muscle cells in the intervention group were slightly edematous, and the structure of the myogenic fiber bundles was clear; part of the myogenic fiber bundles were broken, and the structure of the Z-lines was clear and more neatly arranged. (4) Gastrocnemius muscle tissue MyoD, MyoG and Pax7 mRNA transcript levels:compared with the blank group, MyoD, MyoG and Pax7 mRNA transcript levels were significantly higher in both the model group and the intervention group (<italic>P</italic><0.05); compared with the model group, MyoD, MyoG and Pax7 mRNA transcript levels were significantly higher in the intervention group (<italic>P</italic><0.05).
