Several erythropoietin-producing hepatocellular receptor B family (EPHB) and their ligands, ephrinBs (EFNBs), are involved in blood pressure regulation in animal models. We selected 528 single nucleotide polymorphisms (SNPs) within the genes of EPHB6, EFNB2, EFNB3 and GRIP1 in the EPH/EFN signalling system to query the International Blood Pressure Consortium dataset. A SNP within the glutamate receptor interacting protein 1 (GRIP1) gene presented a p-value of 0.000389, approaching the critical p-value of 0.000302, for association with diastolic blood pressure of 60,396 individuals. According to echocardiography, we found that Efnb3 gene knockout mice showed enhanced constriction in the carotid arteries. In vitro studies revealed that in mouse vascular smooth muscle cells, siRNA knockdown of GRIP1, which is in the EFNB3 reverse signalling pathway, resulted in increased contractility of these cells. These data suggest that molecules in the EPHB/EFNB signalling pathways, specifically EFNB3 and GRIP1, are involved blood pressure regulation.

Study Objectives: Insomnia with objective short sleep duration is associated with increased hypertension risk. We aimed to explore the mechanism underlying the association between objective short sleep duration and hypertension in patients with chronic insomnia disorder (CID) by multi-omics.
Methods: CID was defined according to International Classification of Sleep Disorders-3, and objective short sleep was based on the median value of total sleep time of the overall subjects during an overnight polysomnography.

Background: Management of acute aortic dissection (AAD) caused by retrograde perfusion through the femoral artery during minimally invasive cardiac surgery (MICS) remains controversial. We present a case of AAD occurring during the late cardiopulmonary bypass (CPB) phase, which was successfully managed by vascular graft replacement, without altering the blood supply route.
Case Presentation: A 63-year-old man was scheduled for totally endoscopic aortic valve replacement.

Aim/hypothesis: Pilots with type 1 diabetes are required to perform capillary glucose monitoring regularly during flights. Continuous glucose monitoring (CGM) may be an effective and more practical alternative. This study aimed to assess the accuracy of CGM systems against self-monitoring of blood glucose (SMBG) during a hypobaric flight simulation.

Bacterial meningitis is a rare but severe disease with a high mortality. The most frequent pathogens in adults are pneumococcus, meningococcus and Listeria. The most important key symptoms are headache, meningism and fever; however, the absence of individual cardinal symptoms does not exclude the diagnosis.

Invading blood cells, extracellular tissue, and soluble mediators all play important roles in the wound-healing process. There is a substantial global burden of disease and mortality attributable to skin defects that do not heal. About 1% to 2% of the population in industrialized nations suffers from chronic wounds that don't heal, despite healthcare breakthroughs; this condition is very costly, costing about $25 billion each year in the US alone.
