  • Local Application of Paclitaxel for Prevention Restenosis of Vein Graft in Rabbits

    Abstract: Objective To investigate the effect of keeping implanted vein graft from restenosis by local application of paclitaxel. Methods Ninetysix New Zealand rabbits were randomly divided into three groups, control group (n=32), group Ⅰ(n=32), group Ⅱ(n=32). The vein graft stenosis model was made in all rabbits. In group Ⅰand group Ⅱ, 1μg and 8μg of paclitaxel was applied locally in pluronic gelatin respectively. There were no local treatment in control group. Grafts were harvested at 1, 2, 4, and 6 weeks and underwent morphological analysis as well as immunohistochemical analysis. Results The intimal thickness in group Ⅱ were significantly decreased compared to those in control group at 1,2,4, and 6 weeks after operation (30.10±4.50μm vs. 48.20±9.16μm, 40.70±6.91μm vs. 54.20±8.67μm, 54.70±7.11μm vs. 68.60±13.72μm, and 68.70±8.24μm vs. 76.40±12.98μm, Plt;0.05). The CD8 positive cells and metallothionein positive cells in group Ⅰand group Ⅱ were significantly decreased compared to those in control group (Plt;0.05). Conclusion The results suggest that perivascular application of paclitaxel inhibits neointimal hyperplasia of vein grafts in a rabbit model, and paclitaxel may have a therapeutic potential for the treatment of vein graft disease.

  • Research progress on electrical impedance tomography in pulmonary perfusion

    Electrical impedance tomography (EIT) is an emerging technology for real-time monitoring based on the impedance differences of different tissues and organs in the human body. It has been initially applied in clinical research as well as disease diagnosis and treatment. Lung perfusion refers to the blood flow perfusion function of lung tissue, and the occurrence and development of many diseases are closely related to lung perfusion. Therefore, real-time monitoring of lung perfusion is particularly important. The application and development of EIT further promote the monitoring of lung perfusion, and related research has made great progress. This article reviews the principles of EIT imaging, lung perfusion imaging methods, and their clinical applications in recent years, with the aim of providing assistance to clinical and scientific researchers.
