摘要
背景:肌腱损伤是一种主要的骨科疾病。超声靶向微泡破坏(UTMD)是一种很有前途的基因转染方法,可用于肌腱损伤的治疗 目的:利用UTMD体外研究最佳转化生长因子(TGF- macrophach)短发夹RNA (shRNA)序列和转染条件,并在体内鉴定其对大鼠跟腱损伤早期黏附修复的抑制能力。 方法:选择最佳序列,荧光显微镜下分析,体外实时定量逆转录聚合酶链反应。将40只跟腱损伤大鼠在体内分为5组:(1)对照组,(2)质粒组,(3)质粒+超声组,(4)质粒+微泡组,(5)质粒+微泡+超声组,治疗14天后安乐死。通过黏附评分和病理检查评估TGF-表达。 结果:体外给药的最佳条件为输出强度为1W/cm2,占空比为30%,照射时间为60 s (P <0.05)。5组质粒转染效率高于其他组(P <0.05)。5组黏附指数评分最低,TGF-表达最少(P <0.05)。与其他组相比,第5组的炎症反应较轻。 结论:UTMD传递TGF- shRNA是治疗体内肌腱损伤的一种有效方法。
