摘    要:目的观察沙美特罗/N酸氟替卡松对中重度持续支气管哮喘(简称哮喘)患者转化生长因子p1(transforminggrowthfactor—β1,TGF-β1)/Smad通路的影响。方法中重度持续哮喘患者30例,对照组20例。哮喘组给予规律吸入沙美特罗/N酸氟替卡松50/250/xg,2次/d,持续6个月。酶联免疫吸附试验(ELISA法)定量测血清TGF-β1、Smad2表达,宝石能谱高分辨率CT(HRCT)扫描测量气道壁厚度/气道外径(T/D)、气道壁面积占气道总面积百分比(WA%)评估气道重塑程度。结果哮喘组(治疗前)血清TGF-β1(301.5±27.3)ng/L、Smad2(1182.1±50.6)ng/L与对照组TGF—β1(55.2±12.8)ng/L、Smad2(796.4±56.2)ng/L比较差异有统计学意义(t=8.52,t=5.90,P值均〈0.05),哮喘组(治疗后)TGF-β1,(96.1±25.6)ng/L、Smad2(853.4±49.7)ng/L与哮喘组(治疗前)比较差异具有统计学意义(t=7.21,t=3.13,P值均〈O.05),哮喘组(治疗后)血清Smad2与对照组比较差异无统计学意义(t=0.24,P〉o.05);哮喘组(治疗前)T/D(23.66士4.06)%较对照组(19.79士3.37)%增加,差异有统计学意义(t=3.45,P〈O.05),哮喘组(治疗前)wA%(69.24±6.03)‰值与对照组(51.67±4.55)%比较差异有统计学意义(t=3.77,P〈O.05)。规律吸入沙美特罗/丙酸氟替卡松6个月后,哮喘组(治疗后)T/D(20,43±3.00)%、WA%(58.40±3.85)%下降,与哮喘组(冶疗前)比较差异有统计学意义(t=2.96,t=3.05.P值均〈0.05),哮喘组(治疗后)T/D与对照组比较差异无统计学意义(t=0.95,P〉0.05),气道重塑减轻。结论哮喘患者气道重塑伴随血TGF-β1、Smad2蛋白的表达增加,规律吸入沙美特罗j丙酸氟替卡松可以通过减少血清TGF-β1、Smad2蛋白的表达,从而减轻哮喘患者气道重塑。调节TGF-β1/Smad通路可能是治疗哮喘气道重塑的新策略。

Abstract:Objective To observe the effects of Salmeterol/fluticasone propionate accuhalar on the airway remodeling and the expression~ of transforming growth facto-β1 (TGF-β1), Smad2 in asthmatic patients. Methods Thirty patients were diagnosed as patients with moderate-severe persisteut asthma (asthma group) and other twenty were the healthy subjects (control group). The patients with asthma were treated with Salmeterol/fluticasone propionate accuhalar for 6 months. Levels of TGF -β1 , Smad2 in plasma were detected by ELISA. Quantitative assessment was used to analyze the thickness of airway wall (T, T/D) and airway wall area(WA, WAg/0) by HRCT. Results @Plasma TGF-β1, Smad2 levels in asthma group (pre-treatment)(301. 5±27. 3) ng/I,,(1 182.1±50.6) ng/L were higher than those in control group (55.2±12.8) ng/L,(796.4±56.2) ng/L ( P 〈,0.05), while decreased in asthma group (after treatment) (96.1 ± 25.6) ng/L, (853.4 ± 49.7) ng/L as compared with asthma group (pre treatment) (P 〈0.05). (2)The values of T/D and WA% in asthma group (pre treatment)(23.66±4.06) % ,(69.24±6.03)% were higher than those of control group (19.79±3.37) % ,(51.67±4.55), while decreased in asthma group (after treatment)(20.43± 3.00)%, (58.40± 3.85)% as compared with asthma group (pre-treatment) ( P 〈 0.05). Conclusions Salmeterol/fluticasone propionate accuhalar could decrease the expression of TGF-β1, Smad2 in moderate-severe persistent asthmatic patients and inhibit airway remodeling.
