Published: April 2010

While recent developments have allowed greater insight into the vascular pathobiology and intimal hyperplasia, very few of these advances have led to improved clinical care of hemodialysis vascular accesses. Indeed the most common procedure for the treatment of access stenosis and thrombosis is the same model for the creation and study of intimal hyperplasia. The evolution of our understanding of vascular thrombosis is reviewed with a current concept that includes a dynamic interplay of the biophysics, chemistry and biology of the blood vessel with the blood and its constituents. Implications for possible future interventions based on these novel concepts are offered, and the significance of improving our understanding of the pathobiology is emphasized.

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.

Article Synopsis
  • Intimal hyperplasia (IH) is a major issue in vascular interventions, and this study investigates the role of gangliosides GA2 in its development.
  • Researchers found that GA2 levels were significantly higher in atherosclerotic mouse aortae and plasma, and injecting GA2 worsened IH by interacting with macrophages.
  • The study reveals that GA2 activates caspase-4 and promotes pyroptosis in macrophages, suggesting a new mechanism for IH that could lead to potential diagnostic and treatment strategies.

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.
