Arterial occlusive disease is the leading cause of death in Western countries. Core contemporary therapies for this disease include angioplasties, stents, endarterectomies and bypass surgery. However, these treatments suffer from high failure rates due to re-occlusive vascular wall adaptations and restenosis. Restenosis following vascular surgery is largely due to intimal hyperplasia. Intimal hyperplasia develops in response to vessel injury, leading to inflammation, vascular smooth muscle cells dedifferentiation, migration, proliferation and secretion of extra-cellular matrix into the vessel's innermost layer or intima. In this review, we describe the current state of knowledge on the origin and mechanisms underlying the dysregulated proliferation of vascular smooth muscle cells in intimal hyperplasia, and we present the new avenues of research targeting VSMC phenotype and proliferation.

Background: The arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis. AVF stenosis is a common complication, often requiring balloon angioplasty. For recurrent stenosis, AVF stenting may be an option.

Cardiovascular diseases (CVDs) are the foremost cause of mortality worldwide, with incidence and mortality rates persistently climbing despite extensive research efforts. Innovative therapeutic approaches are still needed to extend patients' lives and preserve their health. In the present study, novel supramolecular nanomedicine with both nitric oxide (NO) and antioxidant releasing ability was developed to enhance therapeutic efficacy against vascular injuries.

Ethnopharmacological Relevance: Astragali Radix-Angelicae Sinensis Radix is an important traditional Chinese medicine used for the treatment of cardiovascular diseases. Our previous studies have shown that Astragali Radix-Angelicae Sinensis Radix can inhibit vascular intimal hyperplasia and improve the blood vessel wall's ECM deposition, among which six main active components can be absorbed into the blood, suggesting that these components may be the main pharmacodynamic substances of Astragali Radix-Angelicae Sinensis Radix against vascular intimal hyperplasia.
Aim Of The Study: A mouse model of atherosclerosis was used to study the relationship between the anti-intimal hyperplasia effect of Astragali Radix-Angelicae Sinensis Radix and the inhibition of VAF activation and ECM synthesis.

Synthetic vascular grafts are promising conduits for small caliber arteries. However, due to restenosis caused by intimal hyperplasia, they cannot keep long patency in vivo. In this work, through single cell RNA sequencing, we found that thrombospondin-1 (THBS1) was highly expressed in the regenerated smooth muscle cells (SMCs) in electrospun polycaprolactone (PCL) vascular grafts.
