Introduction: Bone marrow-derived mesenchymal stem cell-derived extracellular vesicles (BMSC-EVs) are widely used for therapeutic purposes in preclinical studies. However, their utility in treating diabetes-associated atherosclerosis remains largely unexplored. Here, we aimed to characterize BMSC-EV-mediated regulation of autophagy and macrophage polarization.

In this study, we explored the efficacy and possible mechanisms in combination of CIMT and iTBS through behavioral evaluation, RNA sequencing, Golgi staining, transmission electronic microscope (TEM), high-performance liquid chromatography (HPLC), western blotting (WB) and immunofluorescence. Firstly, we observed that combination therapy is safe and effective, and it can significantly reduce the number of immature dendritic spines and increase the number of functional dendritic spines, the amount of glutamate (Glu) and the expression of Glu1 receptor (Glu1R).

Alcoholic osteonecrosis of the femoral head (AIONFH) is caused by long-term heavy drinking, which leads to abnormal alcohol and lipid metabolism, resulting in femoral head tissue damage, and then pathological necrosis of femoral head tissue. If not treated in time in clinical practice, it will seriously affect the quality of life of patients and even require hip replacement to treat alcoholic femoral head necrosis. This study will confirm whether M2 macrophage exosome (M2-Exo) miR-122 mediates alcohol-induced BMSCs osteogenic differentiation, ultimately leading to the inhibition of femoral head necrosis.

Disulfiram (DSF), which has been traditionally used to treat alcoholism, has been shown to inhibit tumor growth, indicating its potential as an anticancer agent. However, its development and application are hindered by its poor water solubility, instability in physiological environments, and low bioavailability. In this study, phenylboronic acid-chitosan (PBA-CS) grafts were synthesized using the carbodiimide method.

Ethnopharmacological Relevance: Bovis calculus (BC) has a medicinal history of over 2,000 years in treating stroke in China. Bovis Culus Sativus (BCS) has similar pharmacological effects to BC. Due to the scarcity of BC, BCS is often used as a substitute for BC in clinical practice for treating stroke in traditional Chinese medicine.
