8. 关于用于尝试童颜但是出现结节的宝,看这里,谨防需要请转存。
High-Intensity Focused Ultrasound as a Novel Approach for the Management of Non-inflammatory Nodules After Poly-L-Lactic Acid (PLLA) Injections 就是说,高强度超声可以作为一种搞plla注射之后而产生的非炎症性结节的手段(翻译的好别扭感觉,就这样吧,你们看的懂)
The biological rationale for the observed efficacy of HIFU remains speculative. We hypothesize it could lie in HIFU’s ability to generate well-defined zones of thermal
coagulation that selectively disrupt granulomatous tissue and induce a local ‘‘reset’’ of the inflammatory response [4, 5]. Granulomatous PLLA nodules represent a foreignbody reaction characterized by giant cells and macrophage activation
HIFU 能够在组织内形成精准可控的热凝固区(我觉得取决于医生操作),选择性破坏肉芽肿组织,并在局部诱导炎症反应的“重置” 。PLLA 结节本质上是一种异物反应性肉芽肿(利用炎症刺激),其特征包括巨噬细胞和多核巨细胞的活化。通过将聚焦能量精确作用于特定深度,HIFU 可能打断这一异常炎症过程,从而促进结节的消退。
具体治疗参数细节All patients underwent HIFU therapy with transducers at depths of 4.5 mm, 3.0 mm, and 1.5 mm (with 1.5J, 0.7J, and 0.5J, respectively; 750 shots per cartridge)
