Development of the aorta and pulmonary artery is a complex process involving multiple molecular genetic pathways that modulate morphogenesis of the outflow tracts and the anastomosis of branch vessels. Recent genetic studies of the cardiovascular system demonstrate that congenital and adult onset progressive disorders of the great vessels such as aneurysms are components of generalized vascular, cardiac, and extracardiovascular syndromes. Current paradigms suggest that aortic disease is founded in patterning anomalies of the conotruncus that occur in utero. These aberrations can be consequences of genetic aberrations in transcriptional regulation of signal transduction both within and outside the developing great vessels.

Extracellular matrix (ECM)-based small-diameter vascular grafts (SDVGs, inner diameter (ID) < 6 mm) hold great promise for clinical applications. However, existing ECM-based SDVGs suffer from limited donor availability, complex purification, high cost, and insufficient mechanical properties. SDVGs with ECM-like structure and function, and good mechanical properties were rapidly prepared by optimizing common materials and preparation, which can improve their clinical prospects.

Organoids, exhibiting the capability to undergo differentiation in specific in vitro growth environments, have garnered significant attention in recent years due to their capacity to recapitulate human organs with resemblant in vivo structures and physiological functions. This groundbreaking technology offers a unique opportunity to study human diseases and address the limitations of traditional animal models. Cardiovascular diseases (CVDs), a leading cause of mortality worldwide, have spurred an increasing number of researchers to explore the great potential of human cardiovascular organoids for cardiovascular research.

Forging additive hybrid manufacturing integrated the high efficiency of forging and the great flexibility of additive manufacturing, which has significant potential in the construction of reactor pressure vessels (RPVs). In the components, the heat-affected zone (HAZ, also called as bonding zone) between the forged substrate zone and the arc deposition zone was key to the final performance of the components. In this study, the Mn-Mo-Ni welding wire was deposited on the 16MnD5 substrate with a submerged arc heat source.

In recent years, with the deepening of mesentery research, it is found that its blood vessels, nerves, lymphoid tissue, adipose tissue and other structures play an important role in the occurrence and development of Crohn disease, and the degree of lesion is related with the disease process, surgical difficulty, the occurrence of intraoperative complications and postoperative recurrence. The optimal surgical strategy of Crohn disease based on mesenteric involvement has received great attention. Multiple retrospective studies found that extended mesenteric resection and Kono-S anastomosis potentially could reduce the rate of postoperative recurrence.

Aorticopulmonary paragangliomas are exceedingly rare tumors in pediatric populations. Complete surgical resection is the only curative treatment. However, resection is challenging due to the vascularity of paragangliomas and their close relationship with the great vessels.
