The experiments showed that whenatomization took place under the conditions where the combination of a pyrolytic coating graphitetube and fast raising temperature were used and the temperature was stable, the signal peak shapescould be improved, the sensitivity was enhanced, and the memory effect was removed. The vanadium infood and traditional Chinese medicinal herbs can be accurately determined using the standard curvemethod.展开更多
目的:观察麻黄附子细辛汤联合沙美特罗替卡松粉吸入剂治疗老年慢性支气管哮喘的临床疗效。方法:将98例老年慢性支气管哮喘患者按照随机数字表法分为对照组47例和治疗组51例。对照组给予沙美特罗替卡松粉吸入剂经口吸入,治疗组在对照组...目的:观察麻黄附子细辛汤联合沙美特罗替卡松粉吸入剂治疗老年慢性支气管哮喘的临床疗效。方法:将98例老年慢性支气管哮喘患者按照随机数字表法分为对照组47例和治疗组51例。对照组给予沙美特罗替卡松粉吸入剂经口吸入,治疗组在对照组治疗的基础上联合麻黄附子细辛汤。比较两组患者的临床疗效、不良反应发生率及治疗前后中医证候积分、哮喘控制测试(asthma control test,ACT)评分、肺功能[用力呼气流量峰值(forced expiratory peak,PEF)、用力肺活量(forced vital capacity,FVC)、一秒用力呼气容积(forced expiratory volume in one second,FEV_(1))]、细胞因子水平[白细胞介素-4(interleukin-4,IL-4)、干扰素-γ(interferon-γ,IFN-γ)、转化生长因子-β1(transforming growth factor-β1,TGF-β1)]变化情况。结果:对照组有效率为87.23%,治疗组有效率为98.04%,两组患者有效率比较,差异具有统计学意义(P<0.05)。两组治疗后中医证候积分低于本组治疗前,ACT评分高于本组治疗前,且治疗后组间比较,差异具有统计学意义(P<0.05)。两组治疗后PEF、FVC及FEV_(1)高于本组治疗前,且治疗后治疗组高于对对照组,差异具有统计学意义(P<0.05)。两组患者治疗后IFN-γ高于本组治疗前,IL-4及TGF-β1低于本组治疗前,且治疗后组间比较,差异具有统计学意义(P<0.05)。两组不良反应发生率比较,差异无统计学意义(P>0.05)。结论:麻黄附子细辛汤联合沙美特罗替卡松粉吸入剂治疗老年慢性支气管哮喘,可明显改善患者的临床症状及肺功能,有效拮抗炎性细胞因子及转化生长因子表达,减轻呼吸道炎症反应,阻止气道重塑发生。展开更多
