摘要 目的建立新生大鼠坏死性小肠结肠炎(NEC)模型,探讨肝素结合性表皮生长因子样生长因子(HB-EGF)对NEC新生大鼠回肠组织促炎因子白细胞介素-12(IL-12)和白细胞介素-18(IL-18)水平的影响及其对肠道保护作用的机制。方法 30只SD新生大鼠随机分为3组:NEC模型组(缺氧复氧冷刺激+人工喂养)、HB-EGF干预组(缺氧复氧冷刺激+HB-EGF+人工喂养)和正常对照组(母乳喂养),观察造模和干预后大鼠一般状况和盲肠近端回肠组织病理改变及用ELISA双抗夹心法检测回肠组织IL-12和IL-18的水平。结果HB-EGF干预组病理评分≥2分的发生率小于NEC模型组(20%vs 90%,P<0.05);HB-EGF干预组的IL-12及IL-18水平均低于NEC模型组(P<0.01)。结论 HB-EGF可能通过降低NEC新生大鼠中促炎症因子IL-12及IL-18水平,从而起到保护肠道的作用。
