ABSTRACT
Objective To investigate the relationship between pulmonary arterial ( PA) enlargement and pulmonary function in patients with chronic obstructive pulmonary disease (COPD).Methods From December 2012 to June 2016,78 patients with acute exacerbation of COPD in the Eighth People＇s Hospital of Qingdao were selected. According to pulmonary CT findings,they were divided into two groups : PA enlargement group (38 cases) was PA＞3.0cm,normal PA group(40 cases) was PA≤3.0cm.FEV1and FVC of stable phase were compared.Results The FEV1of men in the A enlargement group was (1.08 ±0.44)L,that in the normal PA group was (1.44 ±0.66)L,the difference was statistically significant (t＝2.27,P＝0.028).The FEV1of women in the PA enlargement group was (0.90 ±0.41)L,which in the normal PA group was (1.35 ±0.58)L,the difference was statistically significant (t＝2.28,P＝0.026).Correlation analysis showed that the diameter of PA was negatively related with FEV 1/FVC(r＝-0.509,P＝0.001),PA enlargement was related with lung function decline.Conclusion COPD patients with PA enlargement are more associated with accelerated loss of lung function and should be treated early.
ABSTRACT
Objective To know the sleeping quality of clinical nurses in Urumqi, and analyze the influencing factors, put forward the corresponding countermeasures for different factors to improves the sleeping quality. Methods Randomly selected 407 nurses in clinical departments as the research objects in Urumqi top three hospitals, using the Pittsburgh sleep quality index scale (PSQI) and general situation questionnaire to investigate, and then analyzed the results of the survey. Results The incidence rate of sleeping disorders in emergency nurses was the highest (80.00%), followed by pediatric, intensive department, internal medicine, surgical department, operating room, outpatient and others was the lowest (39.02%). Gender (t=-2.015, P =0.045), age (F=8.509, P =0.000), establishment(F=3.609, P =0.013) were the influence factors of PSQI scores. Only the difference of the scores of hypnotic drugs between different ethnic groups was significant, P0.05. Conclusions Poor sleeping quality of nurses existed in every department, its sleeping quality status, department, gender, age and establishment have certain correlation, interventions should be strengthened, to improve the overall level of sleeping.
