摘要
目的 通过构建慢性哮喘大鼠模型,研究白头翁皂苷B4对慢性哮喘大鼠肺组织中转化生长因子-β1(transforming growth factor β1,TGF-β1)、p38丝裂原活化蛋白激酶(mitogen activated protein kinase,p38 MAPK)的调控作用和氧化应激水平的影响。方法 构建慢性哮喘大鼠模型,将72只SD大鼠随机分为健康对照组、慢性哮喘组、地塞米松组、白头翁皂苷B4高剂量组、白头翁皂苷B4低剂量组、白头翁皂苷B4+TGF-β1激活组,每组12只。检测各组大鼠肺泡灌洗液中各种类细胞数量;苏木精-伊红(hematoxylin-eosin,HE)染色法检测各组大鼠肺组织病理学变化;试剂盒检测各组大鼠肺组织中超氧化物歧化酶(superoxide dismutases,SOD)、丙二醛(malondialdehyde,MDA)含量及炎症因子白细胞介素-1β(interleukin-1β,IL-1β)、白细胞介素6(interleukin-6,IL-6)、血清肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)水平;Western blot法检测TGF-β1、p38MAPK、p-p38MAPK蛋白的表达。结果 健康对照组大鼠肺组织结构完整;与健康对照组相比,慢性哮喘组大鼠出现明显肺损伤,肺泡灌洗液中细胞总数、中性粒细胞、嗜酸性粒细胞、淋巴细胞数量升高,肺组织MDA[(0.96±0.15)vs(19.36±1.79)μmol/L]、IL-1β、IL-6、TNF-α含量和TGF-β1蛋白表达量[0.21±0.06 vs 2.35±0.12]、p-p38MAPK/p38MAPK[0.25±0.07 vs 0.88±0.06]升高,SOD含量[(159.51±6.37)vs(42.15±5.73)U/L]降低,差异均有统计学意义(均P<0.05);与慢性哮喘组相比,地塞米松组、白头翁皂苷B4高剂量组、白头翁皂苷B4低剂量组大鼠肺组织逐渐恢复,肺泡灌洗液中细胞总数、中性粒细胞、嗜酸性粒细胞、淋巴细胞数量降低,肺组织MDA[(19.36±1.79)vs(3.48±0.16)、(3.53±0.31)、(14.25±0.65)μmol/L]、IL-1β、IL-6、TNF-α含量和TGF-β1蛋白表达量[(2.35±0.12)vs(0.57±0.08)、(0.61±0.11)、(1.15±0.12)]、p-p38MAPK/p38MAPK[0.88±0.06 vs 0.41±0.07、0.39±0.05、0.62±0.09]降低,SOD含量[(42.15±5.73)vs(131.62±4.84)、(133.28±4.62)、(95.62±6.68)U/L]升高,差异均有统计学意义(均P<0.05);与白头翁皂苷B4高剂量组相比,白头翁皂苷B4低剂量组、白头翁皂苷B4+TGF-β1激活组肺组织恢复缓慢,肺泡灌洗液中细胞总数、中性粒细胞、嗜酸性粒细胞、淋巴细胞数量升高,肺组织MDA[(3.53±0.31)vs(14.25±0.65)、(15.25±0.62)μmol/L]、IL-1β、IL-6、TNF-α含量和TGF-β1蛋白表达量[(0.61±0.11)vs(1.15±0.12)、(1.95±0.14)]、p-p38MAPK/p38MAPK [0.39±0.05 vs 0.62±0.09、0.69±0.10]升高,SOD含量[(133.28±4.62) vs(95.62±6.68)、(64.16±7.41)U/L]降低,差异均有统计学意义(均P<0.05);地塞米松组与白头翁皂苷B4高剂量组相比,各项指标无明显变化,差异均无统计学意义(均P>0.05)。结论 白头翁皂苷B4可调控TGF-β1/p38MAPK信号通路,抑制TGF-β1表达和p38MAPK激活,从而减轻氧化应激和炎症反应,缓解慢性哮喘,改善病情。
