Skin topical preconditioning before and after surgical procedures is a relatively new concept, particularly in relation to the efficient removal of tissue breakdown products. Clinical trials demonstrate improvements, such as less induration, when surgery is combined with topical product preconditioning and with usage post-surgery.
This trial aimed to assess the efficacy of such a regimen at the molecular level through gene expression studies in combination with clinical assessments.
Six women who underwent medial thigh liposuction administered either a bland moisturizer or the experimental topical products to each side of the surgical area twice daily. Biopsies were taken before any topical application, at 2 and 4 weeks after liposuction. An inflammation-related gene expression analysis was conducted to compare the different conditions. In addition, the degree of induration was assessed in a blinded manner.
Compared with the bland moisturizer, the experimental group demonstrated a hastened immune inflammatory response moving more rapidly to an anti-inflammatory reversal at 2 weeks followed by a wound healing extracellular remodeling effect at 4 weeks. This matched the clinical picture depicting less induration with the treatment.
For patients undergoing body procedures, a topical treatment with the Alastin induces an accelerated healing response, inducing the clearance of "waste" products and the induction of anti-inflammatory genes. Furthermore, this topical treatment stimulates extracellular matrix remodeling, which ultimately leads to less induration.
手术前后进行皮肤局部预处理是一个相对较新的概念,特别是在有效清除组织分解产物方面。临床试验表明,当手术与局部产品预处理及术后使用相结合时,会有一些改善,比如硬结减少。
本试验旨在通过基因表达研究结合临床评估,在分子水平评估这种治疗方案的疗效。
六名接受大腿内侧吸脂术的女性,每天两次在手术区域的每一侧涂抹温和保湿剂或实验性局部产品。在任何局部应用前、吸脂术后2周和4周进行活检。进行炎症相关基因表达分析以比较不同情况。此外,以盲法评估硬结程度。
与温和保湿剂相比,实验组表现出更快的免疫炎症反应,在2周时更快地转向抗炎逆转,随后在4周时出现伤口愈合细胞外重塑效应。这与临床情况相符,即治疗后硬结较少。
对于接受身体手术的患者,使用Alastin进行局部治疗可诱导加速愈合反应,促进“废物”产物清除并诱导抗炎基因表达。此外,这种局部治疗刺激细胞外基质重塑,最终减少硬结。
