Exosomes are a kind of membrane vesicle with a diameter of 30-150 nm. It is formed by the budding of multiple vesicles in cells, which can fuse with the cell membrane and be released into the extracellular matrix. Adipose derived stem cells (ADSCs) have the potential of self-renewal and multi-directional differentiation. They can transport the active substance, regulate the inflammatory response, cell migration, proliferation, differentiation and angiogenesis via the action of paracrine exosomes, so as to enhance the ability of wound repair, promote wound healing, and inhibit the formation of scars. Chronic wounds refer to the wounds that can not reach the anatomic and functional integrity through the normal, orderly, and timely repair process, and the course of the wound healing is more than 4 weeks. At present, there are various treatment methods for chronic wounds, among which ADSCs, although showing a good application prospect, have some limitations due to ethical issues, while exosomes can avoid this problem. This article reviews the treatment of chronic wounds with ADSC exosomes.

Ankle sprains are common in female soccer players. Ankle injuries have the potential to impact balance control, which can further contribute to recurrent injuries. This study aimed to examine if female collegiate soccer players exhibited worse ankle stability and single-leg balance than female non-soccer players, and whether there was a correlation between ankle stability and single-leg balance.

Background: The mechanistic association between the hydraulic forces generated during contrast injection and the risk of coronary injury is poorly understood. In this study, we sought to evaluate whether contrast injections increase intracoronary pressures beyond resting levels and estimate the risk of hydraulic propagation of coronary dissections.
Methods: This is a prospective, single-arm, multicenter study that included patients with nonculprit, non-flow-limiting coronaries.

Background: Chronic kidney disease (CKD) is a significant contributor to the global burden of disease. Among its causes, chronic kidney disease due to type 2 diabetes (CKD-T2D) is the primary subtype. This study aims to provide an updated assessment of the global disease burden of CKD-T2D from 1990 to 2021.
