Abstract: 目的 研究细丝蛋白B(FLNB)在钙化性心脏瓣膜中的表达及其临床意义。方法 2021年8月~2022年1月在我院手术切除的钙化性主动脉瓣标本9例,同期因主动脉夹层行手术切除的正常主动脉瓣膜标本8例作为对照。组织切片茜素红染色观察瓣膜钙化结节。采用免疫组化分析方法对瓣膜中细丝蛋白B的表达进行分析。利用冰冻组织标本进行蛋白质免疫印迹检测,验证相应分子表达水平间差异。结果 钙化瓣膜切片经茜素红染色可以看见明显钙化结节。免疫组化检查显示细丝蛋白B表达于细胞质,钙化瓣膜高于正常瓣膜,钙化组平均光密度为(6.57±1.65)%;对照组为(0.91±0.52)%,两组比较差异有统计学意义(P<0.05),蛋白质免疫印迹结果与之一致。结论 细丝蛋白B在钙化瓣膜中表达增高,可能参与了瓣膜钙化的病理进程。
