Abstract： 目的:探讨VAC促进猪皮肤软组织爆炸伤感染创面血管生成的机制. 方法:用电雷管在4只15～20 kg的小白家猪双侧肩胛及双侧臀部造成16个爆炸伤创面,随机分为对照组和治疗组. 各组创面伤后前3 d不做任何处理,以造成创面感染. 伤后3 d,对照组油纱布换药,治疗组用-15 kPa负压的VAC治疗. 于治疗前和治疗后1, 3, 6, 9, 14, 19, 24 d取创面中心的活组织. 结果:VAC治疗后1 d创面中即有大量毛细血管内皮细胞表达VEGF,治疗后3 d开始下降. 而对照组创面在治疗后9 d开始才有VEGF的大量表达,并在治疗后14 d开始下降. VEGF的受体flk-1的表达,治疗组创面在治疗后1 d开始即大量表达,治疗后6 d开始下降,对照组创面在9 d开始大量表达,治疗后19 d逐渐下降. 结论:VAC促进猪皮肤软组织爆炸伤感染创面血管的生成可能与其促进VEGF和flk-1的表达有关.
