Abstract This work aimed to investigate the effects of calcitonin gene-related peptide (CGRP)-modified mesenchymal stem cells (MSCs) on vascular stenosis in carotid balloon-injured rats. The CGRP gene labeled with EGFP was transfected into bone marrow MSCs, and CGRP protein expression in MSCs was confirmed by immunofluorescence assays. A rat carotid balloon injury model was established using a surgical method. CGRP-modified MSCs were orthotopically transplanted into the injured area of the rats. At 28 days after cell transplantation, EGFP and CD31 expression was detected by immunofluorescence staining. Hematoxylin-eosin (H&E) staining was used to detect the intima/media area… More >

Abstract Tracheal stenosis is a common respiratory disease and is usually treated by stent implantation. However, the implanted stent often causes excessive hyperplasia of trachea granulation tissue, leading to the restenosis. Although surgical removal or chemical suppression can be used to alleviate the restenosis, the efficacy is limited. Thus, restenosis remains a thorny complication. We investigated this issue from the perspective of the “tress-growth”relationship. Firstly, the lower airway of 5 experimental dogs were CT-scanned to reconstruct the 3D numerical models; secondly, the implantations of the Nitinol alloy stents were numerically simulated; thirdly, 45 days after the… More >

Abstract Background. The efficacy of percutaneous coronary intervention (PCI) is limited by the need for repeat revascularization resulting from restenosis. The restenosis rate after treatment for in-stent restenosis (recurrent restenosis) is high (> 30%). Numerous studies have suggested the predictive value of interleukin 6 (IL-6) and transforming growth factor β1 (TGF-β1). Methods. We sought to determine whether serum levels of IL-6 and TGF-β1 could help identify individuals with recurrent restenosis. Thirty seven patients with a history of stent implantation were enrolled and divided into three groups: (1) patients with a current, first restenosis (n = 9);… More >
