  • Adrenal insufficiency after cardiovascular surgery with cardiopulmonary bypass

    Relative/absolute adrenal insufficiency is not uncommmon in the patients undergoing cardiovascular surgery with cardiopulmonary bypass. However, this complication was rarely reported due to its unspecific clinical presentations and the unawareness of ICU physicians and cardiac surgeons. However, this puts them on a higher risk of hemodynamic instability and cardiovascular adverse events during hospitalization. Systematic reviews concentrated on it are rarely reported currently. We aim to review the etiology, risk factors, potential pathogenesis and related research progress for this complication.

  • Functional role and underlying mechanisms of neuropilin-1 in proliferation and migration of rat vascular smooth muscle cells

    ObjectiveTo investigate the role and potential mechanisms of neuropilin-1 (NRP1) in the pathogenesis of vein graft failure.MethodsThe rat vascular smooth muscle cells (VSMCs) were transfected with NRP1-shRNA adenovirus and negative control adenovirus respectively. Cell counting kit-8, flow cytometry, Transwell and Western blot were used to investigate the effects of inhibition of NRP1 on VSMCs proliferation viability, apoptosis, migration capacity and its downstream signaling pathway protein expression.ResultsThe proliferation and migration of rat VSMCs could be inhibited after down-regulation of NRP1, and the increase of apoptosis was also observed. Moreover, inhibition of NRP1 significantly reduced Akt and NF-κB phosphorylation in rat VSMCs, but had little effect on activation of ERK1/2.ConclusionNRP1 may promote vein graft hyperplastic remodeling by regulating the proliferation and migration of VSMCs through PI3K/Akt and NF-κB pathways, but further animal study is required.

  • Research progress on silent cerebral infarction after cardiac surgery through cardiopulmonary bypass

    In the absence of symptoms, silent cerebral infarction can be discovered incidentally during an imaging or neuropathological examination. After cardiovascular surgery with cardiopulmonary bypass, the morbidity is high, and it may contribute to neurocognitive dysfunction, symptomatic cerebral infarction and increased risk of death. The embolus caused by various operations intraoperatively are closely associated with this progress. However, controversies over the prevention still persist. As a result, an overall summary of silent cerebral infarction after cardiovascular surgery with cardiopulmonary bypass will be presented in this review.
