摘  要:目的探究小儿定喘口服液在脂多糖诱导的肺炎模型体外和体内的抗炎效果。方法选取BALB/c小鼠完全随机分为对照组、模型组、不同浓度或剂量小儿定喘口服液处理的观察组(浓度指6.25、12.50、25.00、50.00mg/L,剂量指2.5、5.0、10.0、20.0ml/kg,下同),每组6只(观察组指4种药物浓度或剂量各6只)。对照组不给予任何药物处理,模型组应用脂多糖处理,观察组应用小儿定喘口服液。体外用噻唑蓝试验检测小鼠巨噬细胞活力,Greiss反应法测定小鼠巨噬细胞一氧化氮含量,酶联免疫吸附试验(ELISA)测定巨噬细胞炎症因子前列腺素E2(PEG2)、肿瘤坏死因子α(TNF-α)、白细胞介素1β(IL-1β)、IL-6含量;体内ELISA测定血清中的炎症因子TNF-α、IL-1β、IL-6含量,逆转录聚合酶链反应测定肺组织中TNF-α、IL-1β、IL-6mRNA表达量,测定肺泡灌洗液及外周血中白细胞、中性粒细胞、巨噬细胞总数,苏木精.伊红染色观察小鼠肺组织的病理损伤。结果体外实验结果显示不同浓度小儿定喘口服液处理后巨噬细胞活力差异均无统计学意义(P〉0.05);观察组一氧化氮、炎症因子PGE2、TNF-α、IL-β、IL-6含量随小儿定喘口服液浓度增加有降低趋势,并且体内试验结果显示观察组血清中炎症因子TNF-β、IL-1β、IL-6含量[(35±7)、(33±6)、(26±1)、(18±2)ng/L比(66±4)ng/L,(36±4)、(21±9)、(17±9)ng/L比(58±8)ng/L,(67±12)、(45±32)、(33±6)ng/L比(108±22)ng/L]及肺组织中TNF-α、IL-1β、IL-6相对mRNA含量[(3300±300)、(2200±100)、(600±600)比(4200±600),(960±80)、(570±90)、(480±100)、(220±50)比(980±240),(2300±600)、(300±100)、(200±50)比(6800±1200)]明显低于模型组,差异有统计学意义(P〈0.01或P〈0.05)。观察组Objective To explore vitro and vivo anti-inflammatory effects of Xiaoer Dingchuan Koufuye (XDK) in lipopolysaccharide (LPS) induced acute pneumonia mice. Methods BALB/c mice were randomly divided into blank control group, model control group and observation groups with different concentrations or doses of XDK treatment(concentrations including 6. 25, 12. 5, 25, 50 mg/L; doses including 2. 5, 5, 10, 20 ml/kg), with 6 rats in each group. The model control group was treated with LPS, observation groups were treated with XDK. In vitro experiments, 3-(4,5-Dimethyl-2-thiazolyl) -2,5-diphenyl-2-H-tetrazolium bromide (MTT) test was used to detect the activity of mice macrophage ; Greiss reaction method was used to detect nitric oxide (NO) in macrophage; enzyme-linked immunosorbent assay (ELISA) test was used to detect prostaglandin E2 (PEG2 ), tumor necrosis factor α (TNF-α) , interleukin 1β (IL-1β) and IL-6 in macrophage. In vivo experiments, ELISA was used to detect serum TNF-α, IL-1β and IL-6; reverse transcription polymerase chain reaction was used to detect expressions of TNF-α, IL-1β, IL-6 mRNA in lung tissue; numbers of white blood cell, neutrophilic granu- locyte and macrophage in broncho-alveolar lavage fluid and peripheral blood were calculated; pathological damage of lung tissue was observed through hematoxylin F-eosin staining. Results In vitro experiments, macrophage activity showed no difference among groups with different concentrations of XDK treatment( P 〉0.05 ) ; NO, PGE2, TNF-α, IL-1β and IL-6 decreased with the increase of XDK concentration. In vivo experiments, TNF-α, IL-1β, IL-6 and TNF-α, IL-1β, IL-6 mRNA in lung tissue in observation groups were significantly lower than those in model control group[ (35 ±7) ,(33 ±6) ,(26 ±1) ,(18 ± 2) ng/L vs (66 ±4) ng/L; (36 ±4), (21 ±9), (17 ± 9) ng/L vs (58 ± 8) ng/L; (67 ± 12), (45 ± 32), (33 ± 6) ng/L vs ( 108 ± 22) ng/L; ( 3 300 ±
