Objective To investigate the value of electronic bronchoscopy in the diagnosis of children respiratory diseases. Methods The electronic bronchoscopy results in 400 children with respiratory disease were retrospectively analyzed. Results In 400 children, there were 246 cases with simple endobronchial inflammation, 67 cases with bronchial malacia, 38 cases with bronchial stenosis, 23 cases with bronchial foreign , 4 cases with tracheal bronchus, 4 cases with epiglottic cyst, 3 cases with bronchiectasis, 3 cases with endobronchial granulation, 3 cases with laryngomalacia, 2 cases with vascular ring compression of the trachea, 2 cases with laryngeal web, 1 case with subglottic cyst, 1 case with subglottic neoplasm, 1 case with tracheoesophageal fistula, 1 case with bronchial atresia (left) and 1 case with trachea cyst. All the children had no serious complications. Conclusions Electronic bronchoscopy can effectively improve the level of diagnosis and treatment of children' s respiratory system disease, and it is worth of clinical promotion.

Objective To explore the characteristics of attenuated plaque (AP) in culprit lesions for acute coronary syndrome (ACS) in elderly patients.Methods This study included 166 ACS patients meeting the conditions from Jan.1, 2013 to Sep.31, 2014.Clinical data, vascular lesions determined by coronary angiography and intravenous ultrasound (IVUS)-demonstrated characteristics of culprit plaque, which included presence of AP, maximum attenuation arc, extravascular elastic membrane area, lumen area, plaque area, plaque burden and remodeling index, were recorded.Results Compared with non-elderly group, elderly group had a higher proportion of multiple coronary-artery lesions (50.0％ vs.35.1％, x2=6.525, P =0.038), more attenuation plaques (62.0 ％ vs.45.9％, x2 =4.245, P=0.039), a larger maximum attenuation arc[(142±80)° vs.(115±54)°, t=5.254, P=0.000], larger plaque area[(14.2±3.9)mm2 vs.(12.3 ± 4.1) mm2, t=2.325, P=0.022], more plaque burden [(81.1±14.2)％ vs.(76.4±13.5)％, t=2.025, P=0.042] and higher remodeling index [(1.19±0.17) vs.(1.09±0.13), t=4.245, P=0.031].Conclusions The onset of ACS is more closely related with the unstable plaque in elderly patients, and strengthening the measures for plaque stabilization will be helpful in the prevention and treatment of ACS in the elderly.
Résumé
Objective: To explore the clinical efficacy of a new drug for acute coronary syndrome (ACS), ticagrelor in treating the patients with acute ST-segment elevation myocardial infarction (STEMI), and to compare the effect between ticagrelor and clopidogrel in order to obtain the prospective information of ticagrelor in clinical practice. Methods: A total of 307 STEMI patients were divided into 2 groups, Treatment group, the patients received ticagrelor with aspirin, n=157 and Control group, the patients received clopidogrel with aspirin, n=150. With a period of treatment, the major adverse cardiac events (MACE), rate of thrombosis re-formation and routine blood test result were compared between 2 groups. Results: Treatment group presented the better LVDD, LVEF, platelet level and ST-segment recovery than those in Control group, P Conclusion: The clinical effect of ticagrelor is similar to clopidogre for improving the platelet level and cardiac function in STEMI patients, while the clinical advantage reported in abroad should be further studied.
Résumé
Wheezing is one of the most common respiratory symptoms in infant,which caused by diseases including bronchiolitis,interstitial pneumonia,asthma,etc.The infection of virus is the main and most important factor inducing wheezing in infants,the role of bacteria is not clear yet.In recent years,some researches found that bacteria usually colony and infect in the respiratory of children with asthmatic disease that plays important role of the wheezing prognosis in the early neonatal,but this is still controversial.So this article will overview researches of the role of bacterial colonization/infection in wheezing illness in recent years.
