Objective To explore the value of detecting exhaled nitric oxide(FeNO)during systemic glucocorticoid use in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). Methods A randomized controlled study was conducted from January 2019 to December 2021 at the People's Hospital of Meizhou City. The subjects were 58 AECOPD patients,all of whom were tested for FeNO levels. Based on whether the FeNO levels were>25 ppb,they were divided into a high level FeNO group and a low level FeNO group. They were divided into a treatment group and a control group based on whether they received systemic glucocorticoid therapy. The control group received routine treatment,while the treatment group received routine and systemic glucocorticoid therapy. Changes in FeNO and lung function indicators before and after treatment were detected,COPD assessment test(CAT)scores were determined,and differences between groups were compared. Results After systemic glucocorticoid therapy,the high level group of FeNO showed a decrease in FeNO(P<0. 05),while the high level group showed no statistically significant difference in FeNO before and after routine treatment(P>0. 05). The low level group showed no statistically significant difference in FeNO between the treatment group and the control group before and after treatment(P>0. 05). The first second forced expiratory volume(FEV₁)and the ratio of first second forced expiratory volume to forced vital capacity(FEV₁/FVC)in the high level group of FeNO significantly increased after treatment,and the degree of increase in the treatment group was greater than that in the control group(all P<0. 05). The FEV₁ and FEV₁/FVC in low level group of FeNO significantly increased after treatment(all P<0. 05),but the difference between the treatment group and the control group was not significant(P>0. 05). The CAT scores of the high and low levels of FeNO groups decreased after treatment compared to before treatment(all P<0. 05),and the decrease was more significant in the high level FeNO group. Conclusions The implementation of FeNO measurement in AECOPD patients can reflect airway inflammation to a certain extent,predict glucocorticoid treatment response,guide the rational and effective application of systemic glucocorticoid and avoid excessive glucocorticoid use.

目的 调查非重症监护室护士对住院卧床老年患者肺康复的知信行现状,探讨其影响因素。方法 采用自行设计的卧床老年患者肺康复知信行现状调查问卷,对广州市第一人民医院的555 名非重症监护室护理人员进行调查。结果 共回收有效问卷513份。调查对象肺康复知信行总分为（76.01±12.27）分,知识维度、态度维度、行为维度得分分别为（14.09±3.25）、（21.89±3.38）、（40.03±9.87）分。多元回归分析显示,主要影响护士对住院老年卧床患者实施肺康复知信行的因素为护龄、是否参加过肺康复相关培训及科室是否已开展肺康复（P<0.05）。结论 非重症监护室护士对卧床老年患者肺康复的态度积极,行为良好,但知识有待提升。建议开展卧床老年人相关肺康复培训,激励护士主动学习肺康复新理念的积极性和主动性,强化理论联系临床实践,从而提高临床护理质量。

Objective To investigate the knowledge,attitude and practice of non-intensive care unit（ICU）nurses about pulmonary rehabilitation of hospitalized bedridden elderly patients,and to explore the influencing factors．Methods A self-designed questionnaire on the status of knowledge,attitude and practice about pulmonary rehabilitation of bedridden elderly patients was used to investigate 555 non-ICU nurses in our hospital．Results A total of 513 valid questionnaires were collected．The total score of pulmonary rehabilitation was（76.01±12.27）,and the scores of knowledge,attitude and practice were（14.09±3.25）,（21.89±3.38）and（40.03±9.87）,respectively．Multiple regression analysis showed that the main factors affecting nurses' knowledge,attitude and practice in implementing pulmonary rehabilitation for hospitalized elderly bedridden patients were nursing age,whether they had participated in training related to pulmonary rehabilitation and whether pulmonary rehabilitation had been carried out in the unit（P<0.05）．Conclusions Non-ICU nurses have positive attitudes and good practice toward pulmonary rehabilitation for bedridden elderly patients,but their knowledge needs to be improved．It is recommended that training on pulmonary rehabilitation for the bedridden elderly be carried out to motivate nurses to learn new concepts of pulmonary rehabilitation,strengthen the link between theory and clinical practice,and improve the quality of clinical care．

Objective To investigate the changes in the diversity and abundance of intestinal flora during the intensive period of anti-tuberculosis treatment. Methods Stool specimens from 20 patients with newly treated bacteria-positive pulmonary tuberculosis in Guangzhou Chest Hospital, which were treated with the intensive treatment for 1 week and whole intensive treatment, were collected. All the specimens were subjected to 16S rDNA sequencing and bioinformatics analysis. Results The Alpha diversity index Chao1 and observed_otus index of the treatment group with whole process were (97.8±28.3) and (97.6±28.2) respectively, which were higher than (81±34.7) and (81±34.7) of the 1-week treatment group, which had statistical differences (P=0.04;P=0.038). PCoA analysis based on weighted and unweighted Unifrac distance showed that there was no significant difference in the overall flora community structure between the two groups. Among the bacteria families with higher relative abundance, the relative abundance of Bacteroidaceae,Enterococcaceae,Enterobacteriaceae,Erysipelotrichaceae,Porphyromonadaceae and Bifidobacteriaceae in the treatment group with whole process decreased, the relative abundance content of Lachnodoiraceae,Fusobacteriaceae,Prevotellaceae, Rumincoccaceae, and Veillonellaceae increased. By using linear discriminant analysis effect size (LEfse) to analyze the two sets of data, it was found that at the genus level,Rumincoccaceae of Firmicutes and Lactobacillus;Collinsella of Actinobacteria were significantly different species between the groups. Conclusion Compared with 1 week of treatment, the diversity of intestinal flora increased at the end of intensive treatment, but there was no significant difference in the community structure of intestinal flora. The abundance of intestinal Bacteroidaceae decreased, and the abundance of Lachnodoiraceae increased.
