Methods: The rabbit model of maxillofacial soft tissue blast injury was established with the KTY 04 blasting cap. Wound discharge was collected with polyvinyl alcohol sponge and its content of VEGF and bFGF was determined with ELIZA.

• 方法：采用改进的家兔颌面部爆炸伤动物模型，以KTY－04型雷管为爆炸源，复制颌面部爆炸损伤，选用聚乙烯醇（PVA）海绵收集伤口渗液，双抗体夹心酶（ELISA）法检测其中VEGF和bFGF含量。
