文题释义:

超长皮瓣:皮瓣是由有血液供应的皮肤及其附着的皮下脂肪组织所形成。在皮瓣形成与转移过程中,必须有一部分与本体供皮瓣区相连,此相连的部分称为蒂部,以保持血液供应,其他均与本体分离,转移到另一创面受皮瓣区后,暂时仍由蒂部血运供应营养,等受皮瓣区创面血管长入皮瓣,建立新的血运后,再将蒂部切断,始完成皮瓣转移全过程,故又名带蒂皮瓣,但局部皮瓣或岛状皮瓣转移后则不需要断蒂。大鼠超长皮瓣是沿大鼠背部中线设计0.9-1.0 cm×2.5-6.0 cm大小、蒂在尾端的超长随意皮瓣。

高压氧预处理:高压氧预处理一般只是用于正常人进入空气稀薄区的研究,其结论是可提高进驻高原者的抗氧化活力,改善高原低氧环境体内氧化与抗氧化之间的平衡紊乱,并可维持一定的时间,对于降低急性高原反应的发病率有很好的预防及治疗作用,目前已应用在更多疾病治疗过程中。 

 

背景:高压氧治疗能促进皮瓣内微循环再生,增加血管内血流量与血氧含量,对皮瓣淤血改善效果明显。但高压氧预处理在皮瓣移植中的应用研究还未得到足够重视。

目的:建立大鼠背部超长皮瓣模型,观察高压氧预处理在皮瓣淤血形成早期可能发挥的作用。

方法:SD大鼠36只随机分3组,每组12只。3组均在背部设计随意皮瓣9 cm×2.5 cm制成淤血模型。高压氧预处理组在移植前接受4 d的高压氧治疗,1次/d;移植后高压氧治疗组在移植后接受4 d高压氧治疗,1次/d;对照组皮瓣移植后于常压空气中。移植后第3,5天,用苏木精-伊红染色观察组织浸润,免疫组织化学方法分析组织血管内皮生长因子和转化生长因子β表达,第5天计算皮瓣存活率。
结果与结论:移植后5 d对照组皮瓣存活面积较其他两组少(P < 0.05),高压氧预处理组和移植后高压氧治疗组差别不明显(P > 0.05)。移植后3 d和5 d时,对照组皮瓣血管内皮生长因子和转化生长因子β阳性细胞数均低于高压氧预处理组和移植后高压氧治疗组(P < 0.05),而高压氧预处理组和移植后高压氧治疗组之间差异无显著性意义(P > 0.05)。结果说明,高压氧预处理可促进随意皮瓣血管内皮生长因子和转化生长因子β的表达,有利于新生血管的生成,能提高随意皮瓣的成活率。

Abstract:

BACKGROUND: Hyperbaric oxygen (HBO) therapy can alleviate the skin flap congestion by improving the angiogenesis and increasing the oxygen content of blood in skin flaps. Although the HBO therapy ability to increase flap survival has been well described, the research on the application of HBO pretreatment in skin flap transplantation does not arouse adequate concern.
OBJECTIVE: To investigate the effect of HBO pretreatment on early-stage flap congestion in the rat model of over-length dorsal random skin flaps.
METHODS: Thirty-six SD rats were randomly divided into control group (n=12), HBO pretreatment group (n=12) and HBO treatment group (n=12). Rats in the HBO pretreatment group received 4 days of HBO therapy prior to transplantation, once a day. Rats in the HBO treatment group received 4 days of HBO therapy after transplantation. Rats in the control group were raised in the normal conditions after flap transplantation. At postoperative days 3 and 5, rats were sacrificed and the samples were collected. The inflammation of flap tissues was detected using hematoxylin-eosin staining. The expression of vascular endothelial growth factor and transforming growth factor-β was analyzed by immunohistochemistry staining. The flap survival rate was calculated at postoperative day 5.
RESULTS AND CONCLUSION: The flap survival area of the HBO pretreatment group and HBO treatment group was larger than that of the control group (P < 0.05). At postoperative days 3 and 5, the expression levels of vascular endothelial growth factor and transforming growth factor-β in the flap tissue were higher in the HBO pretreatment group and HBO treatment group than the control group (P < 0.05). However, there was no significant difference in the flap survival area and the expression of vascular endothelial growth factor and transforming growth factor-β between HBO pretreatment and HBO treatment groups  (P > 0.05). HBO pretreatment can increase the expression of vascular endothelial growth factor and transforming growth factor-β and promotes angiogenesis in random pattern flaps, thereby improving skin flap survival.
