沙丁胺醇雾化吸入治疗细支气管炎37例疗效观察

    Clinical effect of salbutamol in treatment of bronchiolitis

    • 摘要: 目的: 观察氧启动雾化吸入沙丁胺醇治疗细支气管炎的临床价值。方法: 患儿随机分为治疗组(n=37)、对照组(n=34),对照组予抗感染、抗过敏、激素静脉滴注,必要时吸氧、强心、利尿。治疗组加用氧启动雾化吸入沙丁胺醇3~5天,2次/天。结果: 治疗组在止咳、平喘、哮鸣音消失时间和住院天数均较对照组明显缩短(P<0.001)。结论: 沙丁胺醇雾化吸入治疗细支气管炎疗效肯定,值得临床推广。

       

      Abstract: Objective: This study was designed to characterize the ultrastructure of the coccoid Helicobacter pylori(H. pylori) forms in the tissues of carcinoma.Methods: Transmission electron microscopy(TEM) technique was used to examine the structure of coccoid H. pylori in 4 cases of gastric carcinoma and 2 cases of esophageal carcinoma.Results: It was found that the coccoid H. pylori were scattered in cancer nest and cancer interspace,some of which enterded cancer cells,macrophages and other cells.The coccoid H. pylori appeared to be similar to the L-forms of other bacteria with varying cell shape and size,different cytoplasmic electron densities and defects in cell wall.Two types of coccoid H. pylori could be distinguished in the tissues of carcinoma by TEM.Type A was smaller with higher electron density in the cytoplasma,and flagellation on the cell membrane,suggesting that it could be viable.However,the type B was larger with lower electron density in the cytoplasma,and no flagellation on the cell membrane,suggesting that it could be a degenerative form.Conclusions: The coccoid forms of H.pulori still have certain degree of viability,thus they may play an important role in the transmission of H. pylori,the relapse of H. pylori related disease after treatment and the development of the related carcinoma.
