Objective The purpose of this study was to explore the correlation between peripheral blood eosinophil (EOS) count and smoking history, some inflammatory indicators, lung function, efficacy of ICS, risk of respiratory failure and chronic pulmonary heart disease, risk of acute exacerbation within 1 year, readmission rate and mortality in patients with acute exacerbation of COPD. Methods Retrospective analysis of the baseline clinical data of 816 patients with acute exacerbation of chronic obstructive pulmonary disease in the Department of Respiratory and Critical Care Medicine of the First Affiliated Hospital of Shihezi University from January 1,2019 to December 31,2021. The patients were divided into EOS ≥ 200 cells / μL (High Eosinophi, HE) group and EOS<200 cells / μL (low Eosinophi, LE) group according to whether the peripheral blood EOS was greater than 200 cells / μL at admission. Peripheral venous blood data (including blood eosinophil count, white blood cell count, lymphocyte percentage, neutrophil percentage), blood gas analysis value, lung function index and medication regimen of all patients were collected, and the efficacy of ICS was recorded. The patients were followed up for 1 year to observe the acute exacerbation and readmission rate, and the mortality rate was followed up for 1 year and 2 years. Results Neutrophil count, lymphocyte count and peak expiratory flow (PEF) in HE group were positively correlated with EOS value (P<0.05), and smoking was more likely to increase EOS value. HE group was more sensitive to ICS. The risk of acute exacerbation in HEA group was higher than that in LE group. ICS could reduce the rate of acute exacerbation in HE group. EOS value in LE group was inversely proportional to FEV1 / FVC and MMEF values (P<0.05). The risk of chronic pulmonary heart disease in LE group was higher than that in HE group. The 2-year mortality rate in HE group was higher than that in LE group. Conclusions Peripheral blood EOS count is correlated with some inflammatory indicators, acute exacerbation risk, and lung function. ICS can improve the clinical symptoms and prognosis of patients with higher EOS count.

Objective To explore the application effect of recumbent rehabilitation exercise combined with oscillatory positive expiratory pressure training in pulmonary rehabilitation of patients with moderate to severe inhalation injury. Methods Fifty-seven patients with moderate-to-severe inhalation injuries admitted to the Department of Burns and Plastic Surgery of the People’s Hospital of North Jiangsu Province from January 2021 to March 2023 were selected by convenience sampling. The patients were randomly divided into Group A, Group B, and Group C. Group A received conventional treatment, Group B received the recumbent rehabilitation exercise on the basis of Group A, and Group C received the concussive expiratory pressure training on the basis of Group B. The three groups were compared before and after the intervention with respect to forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), sputum properties, sputum difficulty, sputum viscosity, average daily sputum output, Borg shortness of breath score, and 1-minute sitting and standing test. Results The improvement values of FEV1, FVC, sputum viscosity, average daily sputum discharge, Borg shortness of breath score, and 1-minute sit-to-stand test were compared among the three groups after intervention, and the differences were statistically significant (all P<0.05). The improvement values of Borg shortness of breath score, and 1-minute sit-to-stand test in group B were significantly better than those in group A (all P<0.05). The improvement values of FEV1, FVC, and sputum properties in group C were significantly better than those in group A (all P<0.05), Coughing difficulty, sputum viscosity, total average daily sputum expectoration, Borg shortness of breath score, and 1-minute sit-to-stand test improvement values were significantly better than those of group A (all P<0.05). Improvement values of FEV1, average daily sputum expectoration, and Borg shortness of breath score in group C were significantly better than those of group B (all P<0.05). Conclusion For pulmonary rehabilitation of patients with moderate-to-severe inhalation injuries, prone rehabilitation exercises combined with oscillatory positive expiratory pressure training can effectively improved the patients’ exercise capacity and respiratory function, and improve their quality of life.
Objective To determine if the therapeutic response to an inhaled corticosteroid is attenuated in individuals with asthma who smoke.Methods 38 outpatients with chronic stable asthma who visited during March 2008 and January 2009 were enrolled in the study. 23 cases were nonsmokers and 15 cases were smokers. All of them were treated by daily inhaled budesonide, and β2 agonist when necessary.They were required to record symptoms and peak expiratory flow every day on an asthmatic diary card. Thepatients were followed 28 days. ACT score, asthma-symptom score, Asthma Control Test ( ACT) score,pulmonary function, and peak expiratory flow were compared between the non-smoking and the smoking asthmatic patients. Results All of the patients had statistically significant increases in ACT score, mean morning and night PEF, mean forced expiratory volume in 1 second, and a significant decrease in asthmasymptom score after budesonide treatment compared with before. There were significantly greater changes inany of these parameters in the non-smokers than in the smokers. Conclusions Active cigarette smoking impairs the efficacy of short term inhaled corticosteroid treatment in asthma. This finding has important implications for the management of patients with asthma who smoke.
Objective To explore the effect of systematic respiratory training on lung function in patients with mild to moderate traumatic brain injury. Methods A total of 60 patients with craniocerebral injury who received conservative treatment from January 2015 to June 2017 were selected. These patients were randomly divided into two groups: breathing training group for systematic breathing training and conventional treatment group for conventional rehabilitation training. Pulmonary infection, length of hospital stay, lung function determination, vital capacity, percentage of maximal ventilation, patient’s oxygen saturation, arterial partial pressure of oxygen, peak airway pressure, airway resistance, and respiratory mechanics were observed. Results The pulmonary infection rate and the length of hospital stay in the respiratory training group were 10.0% and (8.17±0.99) days, respectively, which were significantly lower than those in the conventional treatment group [33.3% and (12.67±0.99) days, respectively]; the differences between the two groups were statistically significant (P<0.05). At the same time, pulmonary function, oxygen saturation, arterial oxygen tension, and respiratory mechanics were all better in the breathing training group than those in the conventional treatment group, the differences between the two groups were statistically significant (P<0.05). Conclusion Breathing training can significantly improve the recovery of lung function in patients with mild to moderate traumatic brain injury, reduce the incidence of complications and effectively improve the prognosis.
【Abstract】 Objective To observe the effects of scoliosis on pulmonary function. Methods 31 cases of scoliosis were included and underwent pulmonary function test ( PFT) . The cases were divided into an adolescent group ( 16 cases) and an adult group ( 15 cases) according to age. Predicted value was used as a reference to assess various PFT parameters. Results In both groups, forced expiratory volume in one second, forced vital capacity, and pulmonary diffusion decreased. In the adolescent group, residual volume,functional residual volume, and total lung capacity decreased. In the adult group, vital capacity and maximal voluntary ventilation decreased, the ratio of forced expiratory volume in one second to forced vital capacity decreased, and resonance frequencies increased significantly compared with the adolescent group ( P lt; 0. 05) . Conclusion Scoliosis may lead to restrictive ventilation defect, which is mainly lung volume reduction in adolescent patients and more severe in adult patients.
ObjectiveTo explore the predictive value of fractional exhaled nitric oxide (FeNO) in the treatment response of adult asthmatic patients. Methods64 adult outpatients with asthma from Peking Union Hospital between March and September 2013 were recruited in the study. All patients completed asthma control test (ACT) together with exhaled nitric oxide (FeNO) and pulmonary function test. Then the patients were classified into a higher FeNO group (n=33) and a normal FeNO group (n=31) according to FeNO level. All patients accepted regular inhaled ICS/LABA treatment (salmeterol and fluticasone 50/250). Three months later all patients reaccepted ACT,FeNO and pulmonary function test. ResultsThe ACT score increased in all patients,and was significantly higher in the higher FeNO group than that in the normal FeNO group[22.07±5.49 vs. 19.23±5.48,t=2.893,P<0.05]. The complete control rate of the higher FeNO group was higher than that in the normal FeNO group (42.42% vs. 19.35%,χ2=3.960,P<0.05). The FEV1 and FEV1%pred of two groups both increased significantly (P<0.05),but there was no significant difference between two groups (P>0.05). Correlation analysis showed that FeNO and the declined rate of FeNO was negatively correlated with the ACT score(r=-0.302,P<0.05;r=0.674,P<0.01) and positively correlated with the improvement of ACT score (r=0.514,P<0.01;r=0.674,P<0.01). No significant correlation was found between FeNO and FEV1 or FEV1%pred. ConclusionThe effect of ICS/LABA therapy is better for asthma patients with higher FeNO. FeNO can be used for predicting the response to ICS/LABA therapy in patients with asthma and guiding the treatment.
