Animal Models and Experimental Medicine 2024年第5期 685-695页

作者： chang gao Wenlong Yuan Dongcheng Wang Xin Zhang Tong Zhang Zhimin Zhou Biomedical Barriers Research Center Institute of Biomedical Engineering Chinese Academy of Medical Sciences & Peking Union Medical College Tianjin Key Laboratory of Biomedical Materials Clinical Laboratory Tianjin Hospital

Background: In facial plastic surgery, patients with nasal deformity are often treated by rib cartilage transplantation. In recent years, cartilage tissue engineering has developed as an alternative to complex surgery for patients with minor nasal defects via injection of nasal filler material. In this study, we prepared an injectable nasal filler material containing poly-L-l actic acid(PLLA) porous microspheres(PMs), hyaluronic acid(HA) and adipose-derived mesenchymal stem cells(ADMSCs).Methods: We seeded ADMSCs into as-prepared PLLA PMs using our newly invented centrifugation perfusion technique. Then, HA was mixed with ADMSC-i ncorporated PLLA PMs to form a hydrophilic and injectable cell delivery system(ADMSCincorporated PMH).Results: We evaluated the biocompatibility of PMH in vitro and in vivo. PMH has good injectability and provides a favorable environment for the proliferation and chondrogenic differentiation of ADMSCs. In vivo experiments, we observed that PMH has good biocompatibility and cartilage regeneration ***: In this study, a injectable cell delivery system was successfully *** believe that PMH has potential application in cartilage tissue engineering,especially in nasal cartilage regeneration.

为解决正常使用极限状态下体外束应力增量计算方法存在的效率、精度问题,基于试验结果和相关假定将体外束加固连续刚构视为各单跨加固体系,考虑使用荷载作用下体外束曲线变形特征及与梁体相对位置变化的几何关系,通过理论推导得出单跨加固体系在荷载作用下体外束应力增量计算的简析公式。将各单跨加固体系体外束应力增量进行叠加,导出全桥加固体系体外束总应力增量计算公式,并对不同荷载及布束形式下体外束应力增量计算公式进行了探讨。以一座体外束加固连续刚构实桥为算例,运用上述方法对体外束在正常使用极限状态下的应力增量进行了计算,并将计算结果与有限元模型、参考文献结果进行了对比验证。结果表明:体外束加固连续刚构在正常使用初期,体外索的应力增量变化取决于加固体系所承受的荷载,张拉控制应力对其影响不大,而在使用后期,张拉控制应力对体外束应力增量的影响逐渐加大;所提公式对体外束在正常使用极限状态下的应力增量计算具有较高的精度,最大平均误差在5%以内,能够满足工程计算精度的要求,且使结构设计偏于安全;同时,公式形式简单,避免了复杂的有限元建模与能量变分运算,便于工程技术人员掌握,具有较好的实用性。

以黑龙江省哈尔滨市依兰县丹清河实验林场30块天然次生白桦林样地的1844棵白桦为研究对象,从常用的10个冠幅基础预测模型中选择白桦的最优模型,通过分析单木因子与冠幅的相关性对模型进行再参数化,引入样地水平的随机效应构建天然次生白桦冠幅的混合效应模型。结果表明:Logistic模型最适宜描述白桦的冠幅变化,引入枝下高、高径比和树冠率可以改进模型的预测精度。引入样地水平的随机效应改善了数据的异方差问题,再次提高了冠幅的预测精度。因此,建议在实际生产中采用非线性混合效应模型对天然次生白桦的冠幅进行预测,从而提高冠幅预测的准确率,为合理经营天然次生白桦提供更加科学有效的理论支持。
