Acid α-glucosidase (GAA) is a lysosomal enzyme that hydrolyzes glycogen to glucose. Deficiency of GAA causes Pompe disease (PD), also known as glycogen storage disease type II. The resulting glycogen accumulation causes a spectrum of disease severity ranging from infantile-onset PD to adult-onset PD. Additional non-invasive biomarkers of disease severity are needed to monitor response to therapeutic interventions. ⋯ Exosomes derived from urine or serum are a potential source of biomarkers for Pompe Disease. Further study of the differences in the miRNA transcriptome and proteome content of exosomes may yield new insights into disease mechanisms.

Erxian decoction (EXD) is an empirical formula for treating cardiovascular disease, our previous work has shown that EXD could improve the cardiovascular structure and function in ovariectomized (OVX) rats, but its pharmacological mechanism is still unclear. ⋯ EXD may prevent myocardial tissue damage through induction of the PI3K/AKT signaling pathway, thereby reducing cardiomyocyte apoptosis and inflammation. EXD may be a potential drug for the treatment of postmenopausal cardiovascular disease.
