Objective:To explore the ability of patients with obstructive sleep apnea (OSA) to recognize facial happy and sad expressions and their correlation with cognitive function.Methods:Convenience sampling was used to select 45 OSA patients in the Geriatric Respiratory Sleep Department of the First Affiliated Hospital of Zhengzhou University from February to September 2023 as the observation group, while 45 volunteers without OSA were recruited as the control group. General Information Questionnaire, Montreal Cognitive Assessment (MoCA), Chinese Facial Affective Picture System (CFAPS), and Facial Expression Suite were used to investigate the study participants. E-prime 2.0 software was used to measure the reaction time and subjective intensity of participants' recognition of happy and sad expressions.Results:A total of 90 questionnaires were distributed, 90 valid questionnaires were recovered, and the effective recovery rate was 100.00%. The reaction time to happy expressions was shorter than that to sad expressions in control group ( P<0.05). The OSA group had a shorter reaction time to sad expressions than the control group ( P<0.05), and the reaction intensity scores of sad expressions of all intensities were higher than those of the control group ( P<0.05) .Intensity scores of sad expressions is negatively correlated with MoCA scores in OSA group. Conclusions:Patients with OSA have a high sensitivity to expressions of sadness, as evidenced by short reaction times, high perceived reaction intensity, and a correlation with cognitive function. OSA patients may misunderstand their social partners' intentions and emotional states, leading to social barriers.

Objective:To explore the effect of remote pulmonary rehabilitation management in chronic obstructive pulmonary disease (COPD) patients.Methods:From May 2017 to May 2019, convenience sampling was used to select 114 COPD outpatients in the Respiratory Department of the First Affiliated Hospital of Zhengzhou University. All patients were randomly divided into control group ( n=57) using conventional pulmonary rehabilitation management and observation group ( n=57) using remote pulmonary rehabilitation management, respectively, and the management period was one year. We compared the differences in COPD self-management ability, body mass index, airflow obstruction, dyspnea, exercise capacity (BODE) index, and average annual hospital admission rate between the two groups. Results:After intervention, the scores and the total score of self-management of observation group were higher than those of control group, and the differences were statistically significant ( P<0.01) . The dimension scores and the total score of self-management of observation group after the intervention were higher than those before intervention, and the differences were statistically significant ( P<0.05) . After intervention, the observation group's percentage of forced vital capacity in the first second to predicted value and the 6 minutes walking distance were higher than those of control group, and the dyspnea score and BODE index were lower than those of control group, and the differences were statistically significant ( P<0.05) . The average annual admission rate of the observation group and the control group were 5.41% and 9.06%, respectively. The average annual hospital admission rate of observation group was lower than that of control group, and the difference was statistically significant (χ 2=6.806, P=0.009) . Conclusions:Remote pulmonary rehabilitation management can improve the self-management ability of COPD patients, improve pulmonary function and reduce the admission rate of patients, which is worthy of clinical promotion.
