Synaptotagmin\u20103 (SYT\u20103), by mediating the internalization of the glutamate AMPA receptor GLUA2, may be related to EA's mechanism. This study aims to explore the mechanism by which EA improves limb spasticity after ICH, providing scientific evidence for its clinical application.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>ICH models were established using stereotaxic injection of autologous tail blood into the right striatum. SD rats were randomly divided into Sham, ICH, ICH\u00a0+\u00a0SCRAMBLE, EA, and ICH\u00a0+\u00a0TAT\u2010GLUA2\u20103Y groups. Rats in the EA group received 30\u00a0min of EA treatment daily after ICH. Muscle tone, neurological deficits, and motor function were assessed. After 3 and 7 days of intervention, the motor cortex was dissected for Western blot analysis of SYT\u20103, GLUA2, and P\u2010GLUA2\u2010Ser880 expression. Immunoprecipitation was used to detect the interaction between SYT\u20103 and GLUA2. Nissl staining and NeuN staining were employed to evaluate brain damage. Fluorescence double\u2010labeling technique was used to observe the expression of SYT\u20103 and GLUA2 in the cell membrane and cytoplasm. Transmission electron microscopy was utilized to examine the microstructure of neurons and synapses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Compared to the ICH group, rats in the EA group showed reduced muscle tone in the left limbs and significant improvement in neurological deficits and motor function. In the ICH\u00a0+\u00a0TAT\u2010GLUA2\u20103Y group, the binding of SYT\u20103 and GLUA2 was inhibited, spastic symptoms were alleviated, and membrane expression of GLUA2 increased. In the EA group, SYT\u20103 levels were significantly reduced, GLUA2 expression increased in the membrane and cytoplasm, and P\u2010GLUA2\u2010Ser880 expression decreased.
