目的观察丙卡特罗联合孟鲁司特钠(MK)对小儿支气管哮喘(BA)患者肺功能、气道炎症水平及血清过氧化脂质/过氧化物酶(LPO)水平的影响。方法选择2021年1月—2022年12月河南中医药大学人民医院收治的150例BA患儿,对照组75例给予常规对症治疗与丙卡特罗,研究组75例在对照组基础上给予MK。比较两组的肺功能、气道反应性指标、气道炎症指标、不良反应,并检测血清LPO、嗜酸粒细胞阳离子蛋白(ECP)、白细胞介素-13(IL-13)水平。结果治疗后,2组的一秒用力呼吸容积(FEV1)、FEV1/用力肺活量(FVC)、最大呼气峰流速(PEF)、最大呼气中段流量(MMEF)、50%用力呼气流速(FEF50%)、FEF75%均大于治疗前(P0.05)。结论丙卡特罗联合MK能改善小儿BA患者肺功能、气道反应性指标,缓解气道炎症,降低血清LPO、ECP、IL-13水平,且未增加不良反应。

To study the stratified stability of a water column in the North Passage of the Yangtze River Estuary,a numerical model of the hydrodynamics of this estuary is established using the EFDC *** the basis of EFDC results,this paper derives and pro-vides the discriminative index of water body stability caused by salinity and analyzes the along-range variation in water body strati-fication stability in the North Passage of the Yangtze River Estuary and the periodic variation at a key location(bend area)based on the simulation results of the numerical *** work shows that the water body in the bend area varies between mixed and strati-fied types,and the vertical average flow velocity has a good negative correlation with the differential velocity between the surface and bottom layers of the water *** model simulation results validate the formulae for the stratified stability discriminant during spring tides.
