目的:观察烟雾暴露与戒烟大鼠气道胰岛素样生长因子1(IGF-1)与骨桥蛋白(OPN)的表达变化,探讨烟雾暴露大鼠气道损伤的机制。方法将雄性SD大鼠40只随机分为5组:对照组(C组)、烟雾暴露1个月组(S1组)、烟雾暴露1个月及戒烟1个月组(Q1组)、烟雾暴露3个月组(S2组),烟雾暴露3个月及戒烟1个月组(Q2组),HE染色观察肺组织病理学改变;免疫组化染色检测IGF-1及OPN蛋白在气道的表达;RT-PCR检测肺组织IGF-1及OPN mRNA的表达。结果与C组比较,S1、S2组支气管上皮细胞IGF-1、OPN蛋白及mRNA表达均增强(P<0.05), Q1、Q2组支气管上皮细胞的IGF-1、OPN蛋白及mRNA表达低于各吸烟组(P<0.05),支气管IGF-1蛋白与OPN 蛋白呈正相关(r=0.558,P<0.05)。结论 IGF-1、OPN参与烟雾暴露大鼠的气道重塑,早期戒烟有助于逆转气道重塑。

ObjectiveTo observe the expression changes of insulin-like growth factor 1(IGF-1) and osteopontin (OPN) in rats airway of smoke exposure and smoke cessation, explore the mechanism of smoke exposure rats with airway damage.Methods Forty male SD rats were randomly divided into five groups: control group(C group), smoke exposure 1 month group(S1 group), smoke exposure 1 month and smoke cessation 1 month group(Q1 group), smoke exposure 3 months group(S2 group), smoke exposure 3 months and smoke cessation 1 month group(Q2 group).The lung tissue airway remodeling were observed using HE staining. The expression of IGF-1 and OPN protein in bronchial of each group was evaluated by immunohistochemistry. The expression of IGF-1 and OPN mRNA in bronchial of each group was detected by Reverse Transcription-Polymerase Chain Reaction.Results S1, S2 groups of IGF-1, OPN protein and mRNA which were expressed in bronchial epithelial cells were significantly higher than C group (P<0.05). Q1, Q2 groups were lower than the smoke exposure(P<0.05). In bronchial, IGF-1 protein was positively related with OPN protein(r=0.558,P<0.05).ConclusionIGF-1 and OPN participate in airway remodeling with smoke exposure of rats. Early to give up smoking helps to reverse the airway remodeling.
