Circulating Neutrophil Counts Decrease in Response to Mitigated Air Quality in Stable COPD Patients

This three-year study, based on the Guangzhou Institute of Respiratory Disease （GRID）, chronic obstructive pulmonary disease （COPD） Biobank, was conducted in 36 COPD patients to estimate whether changes in levels of leukocytes, erythrocytes, hemoglobin, and platelets were related to changes in air pollutant concentration. Daily NO2 levels exhibited significant differences between baseline years and the 2010 Asian Game period. We observed significant reductions in leukocyte and neutrophils counts levels, by 15.51% and 23.01%, from pre-Asian Games to during-Asian Games, respectively. In the post-Asian Game period, most pollutants approximated pre-Asian Game period levels, and similar effects were demonstrated in leukocyte and neutrophil counts. For both items, we identified significant increases resulting from elevated NO2 at lag days 0-2/5-6. We concluded that reductions in pollutants during the intervention period were associated with inactivation of hematological events in COPD.

The Impact of a Multidisciplinary Nursing Model on the Quality of Life of COPD Patients in Remission in the Elderly

Objective:To study the effects of multidisciplinary nursing model on self-care ability,lung function,exercise endurance,negative emotion and quality of life of elderly patients with chronic obstructive pulmonary disease(COPD).Methods:80 patients with COPD hospitalized in the Aerospace Center Hospital from August 2019 to August 2020 were recruited.They were randomly divided into control group and experimental group,with 40 patients in each group.The patients in the control group received routine nursing,and the patients in the experimental group received multidisciplinary nursing intervention on the basis of routine nursing.The nursing observation time of the two groups was 8 weeks.Results:after 8 weeks of nursing intervention,it was found that FEV1/FVC and 6MWD in the observation group were significantly higher than those in the control group(P<0.05).There was no significant difference in SAS score and SDS score between the two groups before nursing,but it was significantly lower in the observation group after nursing.The difference between the above data was statistically significant(P<0.05).The SGRQ score of the observation group was significantly lower than that of the control group(P<0.05).Conclusion:the application of multidisciplinary nursing model can effectively improve the exercise endurance of elderly patients with COPD,eliminate the negative emotions of patients,and improve the quality of life of patients.The comprehensive application value is significant.
