Neuronal apoptosis is an important factor in the etiology of Alzheimer’s disease (AD). Aerobic exercise (AE) enhances learning and memory, improves cognitive impairment, increases telomere binding protein expression, and decreases apoptosis regulators, but it remains unclear whether it can improve cognitive impairment caused by neuronal apoptosis in AD. Therefore, this study investigated whether an 8-week running table exercise intervention could reduce apoptosis and improve cognitive function in the hippocampal neurons of AD model mice. After the exercise intervention, we evaluated the learning memory ability (positioning, navigation, and spatial search) of mice using a Morris water labyrinth, Nissl staining, immunohistochemistry, and protein application to detect hippocampal PI3K/Akt/GSK-3β signaling pathway protein and hippocampal neuronal cell apoptosis protein B cell lymphoma 2 (Bcl-2) and apoptosis-promoting protein bcl-2-related X (Bax) protein expression. The results showed that aerobic exercise improved the location and spatial exploration ability of mice, increased the number of PI3K- and p-Akt-positive cells, increased the expression of PI3K, p-Akt, and bcl-2 proteins, decreased the expression of GSK-3β and Bax proteins, and increased the bcl-2/Bax ratio of mice. The results suggest that aerobic exercise can reduce apoptosis and improve cognitive function in AD mice. The molecular mechanism may involve activation of the PI3K/Akt/GSK-3β signaling pathway.
Background Acupuncture therapy is well known. But there is no report that acupuncture in patients with coagulation dysfunction in stroke may lead to severe soft tissue injury. we report a case of acupuncture leading to severe soft tissue injury.Methods A 63-year-old female patient was hospitalized for stroke rehabilitation. After 2 years of discharge, severe subcutaneous hematoma caused by acupuncture was readmitted to hospital. She received medication and physical rehabilitation. we monitored the international standardized ratio (INR) in plasma and observed the degree of dissipation of subcutaneous hematoma. the changes of patients during treatment were explored by data analysis.Findings Subcutaneous hematoma (area 20×20 cm) disappeared completely after 3 weeks of physical factor therapy. Small range (area ≤3×3 cm) subcutaneous hematoma can heal itself within 2 weeks. Improper acupuncture is only one of the causes of soft tissue injury. Stroke with coagulation dysfunction is not a contraindication of acupuncture treatment.Interpretation Our report suggests that previously unanticipated acupuncture treatment for stroke patients with coagulation dysfunction may lead to severe multiple soft tissue injuries. Although coagulation dysfunction is not a contraindication of acupuncture treatment, acupuncture treatment for stroke patients with coagulation dysfunction should be vigilant, strengthen the level of acupuncture operation, and fundamentally eliminate the problem. These cases are validation and supplement of adverse clinical reactions caused by improper acupuncture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
