However, its pathogenesis is not clear, which may be the result of multiple factors such as obesity, insulin resistance (IR) and inflammatory response. As a novel adipokine, Apelin is closely related to obesity, insulin resistance and inflammation, and may be involved in the pathophysiology of GDM. Studies have shown that Apelin has the effects of reducing blood sugar and improving insulin sensitivity, and is expected to become a new target for GDM treatment.展开更多
