Abstract： Taking the network buzzword "inner volume" as an example, this paper analyzes the communication motivation of the word from the perspective of meme. In addition, the generalization communication of the language meme is also related to social psychological catharsis, user self-expression and group identity, and reflects on the existing problems in the network buzzword communication from the macro, meso and micro levels.

Abstract：目的：制备具有碱性成纤维细胞生长因子缓释性能手术缝纫线的复合材料，并探究其机械性能和体外释药情况。方法：利用静电纺丝技术，通过研究复合材料中物质成分的配比，优化包载效率。并研究聚己内酯-胶原复合结构 (PCL–Col) 对可控释放 bFGF 的影响，来制备具有生物活性与药物缓释性能的手术缝纫线。并观察缝纫线微观结构，检测缝纫线机械性能和载药量。结果：通过扫描电镜结果证明载药的手术缝纫线具有完整的线状结构。进一步通过拉伸与拉伸循环实验证明缝纫线具有良好的机械性能，最后通过酶联免疫吸附实验 (enzyme linked immunosorbent assay，ELISA) 证明所制备的手术缝纫线具备一定的药物缓释性能。结论：通过静电纺丝装置，优化纺丝参数，成功制备了PCL–Col–bFGF的手术缝线复合材料。该缝纫线满足缝合所需要的机械性能同时具备一定的bFGF缓释性能。
