Objective To study the assessment of airway inflammation in asthma patients with airway remodeling by high resolution spiral CT(HRCT).Methods Retrospective analysis on 60 cases of chronicity-persistent period asthma patients with induced sputum IL-4 test,airway mucosa biopsy,HRCT scan; while 20 patients only used HRCT scan as control group.To compare the difference of sputum IL-4,HRCT test of airway wall thickness(WT),wall area(WA)and airway wall relative area(WA％)in different degrees of asthma paitents.Results WA,WA％and WT were significantly increased in different degrees of asthma patients when compared to control group(P<0.05),there were significant difference among each group(P<0.05).WA％and WT were positively correlated with induced sputum IL-4.Conclusion HRCT can effectively evaluate the airway inflammation in airway remodeling of asthma patients,which can be used to evaluate the severity of asthma,treatment effect and follow-up observation.

ObjectiveTo explore the Clinical effect of Tiotropium Bromide combined with seretide in patients with chronic obstructive pulmonary disease at stable period.Methods84 patients with stable COPD from March 2015 to February 2016 in our hospital outpatient respiratory department were randomly divided into control group and treatment group.The control group was treated with Seretide, the treatment group was treated withtiotropium bromide on the basis of control group.Compared the lung function, blood gas analysis, 6-minute walking distance, dyspnea score and quality of life were between the two groups after six months of treatment.ResultsFVC, FEV1and FEV1/ FVC (%) in the treatment group were significantly higher than those in the control group (P<0.05).The score of quality of life and dyspnea in the treatment group were significantly lower than those in the control group (P<0.05).The 6MWD in treatment group was significantly longer than that in control group (P<0.05).PaCO2 was significantly lower in the treatment group than that in the control group, but PaO2 was significantly higher than that in the control group after six months treated(P<0.05).ConclusionThe combination of tiotropium bromide and seretide in patients with chronic obstructive pulmonary disease (COPD) is effective in improving pulmonary function, improving life therapy, and reducing the symptoms of dyspnea.

Objective To investigate the clinical effect of milrinone injection combined therapy in patients with cor pulmonale complicated with respiratory failure and observe the effect of milrinone on blood gas index, blood viscosity and pulmonary arterial pressure.Methods The clinical data of 100 patients with cor pulmonale complicated with respiratory failure were retrospectively analyzed from April 2014 to April 2016.Among them, 50 cases were treated with conventional oxygen therapy, diuretic, asthma and anti-infection treatment.In the control group, 50 cases were treated with milrinone injection as the treatment group.The clinical curative effect and adverse reaction were analyzed.The blood gas analysis index, blood viscosity and pulmonary arterial pressure were measured before and after the treatment.The sputum normal and cyanosis, cough, wet rales and edema time were recorded in the two groups.Results The total effective rate of the treatment group was 92.0%, which was significantly higher than that of the control group 70.0%(P <0.05).After treatment, the hemorheological indexes and blood gas analysis indexes of the two groups improved significantly, However, the improvement of the indicators of the treatment group were significantly better than the control group (P<0.05).The pulmonary arterial pressure in the treatment group was (18.36 ±7.38) mmHg, which was significantly lower than that in the control group (23.79 ±6.14) mmHg (P<0.05); After treatment, the sputum normal and cyanosis in the treatment group, cough, wet rales, edema time were significantly shorter than the control group ( P <0.05 ) .No significant adverse effects were observed in both groups during the treatment.Conclusion The use of milrinone injection comprehensive treatment of pulmonary heart disease with respiratory failure in patients with significant efficacy and safety , but also can help improve blood viscosity and blood gas analysis indicators, reduce pulmonary artery pressure, better promote the rehabilitation of patients.

Objective? To investigate the status of knowledge, attitude, practice of preventing professional exposure to body fluid splash in the medical staff of ENT Department in 6 ClassⅢ Grade A hospitals in Shanxi Province so as to provide evidence for the formulation of prevention and protection measures. Methods? By convenience sampling, a total of 300 medical staff in ENT Department in 6 Class ⅢGrade A hospitals in Shanxi Province from July to September in 2018 were selected as the research objects. The Questionnaire of Knowledge, Belief and Practice of Occupational Protection Among Medical Staff in Otorhinolaryngology Department was used to investigate them. A total of 300 questionnaires were distributed and 265 valid ones were retrieved. Results? The 265 medical staff in ENT Department scored (43.86±6.05) points in knowledge, (34.67±4.79) points in attitude and (32.95±4.98) points in practice, with a total score of (111.48±14.84). Knowledge, attitude and practice were positively correlated (P＜ 0.05). Multivariate linear regression analysis showed that professional title, length of service and exposure history were the influencing factors of occupational protection behavior of medical staff in ENT Department (P＜0.05). Conclusions? The protection of occupational exposure to body fluid splashing of medical staff should start with improving the attitude, and constantly strengthen the attitude in practical work, so as to achieve the purpose of improving the protection behavior.
