摘要: |
目的 观察芍药甘草汤对支气管哮喘SD大鼠Treg/Th17失衡及相关细胞因子IL-2、IL-6、IL-10、IL-17的干预情况,探讨芍药甘草汤防治哮喘的作用机制。方法 SD大鼠40只,♂,随机均分为正常对照组、模型组、芍药甘草汤组、地塞米松组、中西医结合组,每组8只。除正常对照组外其余各组大鼠以卵白蛋白致敏并诱发哮喘模型。正常对照组和模型组生理盐水灌胃,其余组给予对应药物,用Elisa酶联免疫法测定肺匀浆中相关细胞因子IL-2、IL-6、IL-10、IL-17水平。流式细胞仪检测大鼠脾脏CD4+细胞数及比例。结果 与模型组比较,各药物组均可显著降低IL-2、IL-6及IL-17水平(P<0.01),同时能显著升高IL-10含量(P<0.01);各药物组之间比较IL-2、IL-6和IL-10差异无统计学意义(P>0.05);地塞米松组IL-17表达比芍药甘草汤组及中西医结合组均显著降低(P<0.05)。与模型组比较,芍药甘草汤组能显著增加CD4+CD25+Foxp3+Treg细胞的比例(P<0.01)。结论 芍药甘草汤防治哮喘的作用机制可能与调节哮喘大鼠Treg/Th17比例及其相关细胞因子表达的作用有关。 |

Abstract: |
OBJECTIVE To observe the effects of Shaoyao Gancao decoction on the imbalance of Treg/Th17 and their related cytokine in rats with asthma, and to explore its mechanism in treating asthma. METHODS SD rats, ♂, were randomly divided into normal control group, model group, Shaoyao Gancao decoction group, dexamethasone group and integrated TCM-WM group(n=8 for each group). Asthma was induced by intraperitoneal injection of ovalbumin (OVA) and forced inhalation of atomized OVA. Expression of IL-2, IL-6, IL-10 and IL-17 was detected by Elisa method. Numbers of CD4+ T cells in spleen was analyzed by flow cytometry. RESULTS Compared with model group, expression of IL-6, IL-17 and IL-2 in lung homogenate were decreased significantly in the treated group(P<0.01) and expressions of IL-10 was significantly increased in the treated groups(P<0.01). There were no significant differences of expression of IL-2, IL-6 and IL-10 among the treated groups(P>0.05). Expression of IL-17 was decreased significantly in the dexamethasone group than other treated groups(P<0.05). Compared with model group, Shaoyao Gancao decoction increased the percentages of CD4+CD25+Foxp3+ regulatory T cell(P<0.01). CONCLUSION Shaoyao Gancao decoction can efficiently regulate the imbalance of Treg/Th17 and their related cytokine, which may be one of its mechanisms in preventing and treating asthma. |
