Objective: To analyze the clinical features of asymptomatic patients infected with the SARS-CoV-2 novel coronavirus. Methods: The clinical data of 10 asymptomatic cases and 12 symptomatic cases of COVID-19 diagnosed during February 2020 to April 2020 was collected and the clinical features of the two groups of patients were compared. Results: 10 cases of asymptomatic infection and 12 cases of symptomatic patients were tested positive for the novel coronavirus nucleic acid test. There was no significant difference in gender distribution between the two groups (P?0.05); the average age of patients in the asymptomatic group was lower than that of the symptomatic group ( P?0.05), the difference in clinical classification between the two groups was statistically significant (P?0.05); there was no statistically significant difference in the results of chest CT examination involving lung lobes between the two groups (P?0.05), and there was no statistically significant difference in mortality between the two groups (P>0.05). Conclusion: The average age of asymptomatic novel coronavirus infections was lower than that of confirmed cases of COVID-19, mainly among young people. There was no significant difference in clinical classification, mortality and chest CT examination results between symptomatic and asymptomatic cases.
Objective: To explore the effect of respiratory rehabilitation training on the quality of life of pneumoconiosis patients. Methods: 76 pneumoconiosis patients who were treated in our hospital from April 2017 to December 2019 were selected as the research object, and randomly divided into 2 groups according to the order of admission by coin tossing, 38 cases in each group. The control group carried out health knowledge education on the basis of conventional treatment, and the observation group combined with respiratory rehabilitation training on the basis of the control group to compare the quality of life and lung function of the two groups of patients. Results: After 2 months of nursing care, scores of GQOLI-74 scale and pulmonary ventilation function indexes in the observation group were higher than those in the control group, with statistically significant differences (P<0.05). Conclusion: Respiratory rehabilitation training can improve pulmonary ventilation function of pneumoconiosis patients, improve the quality of life of patients, has good clinical application value.
Objective: To analyze the clinical characteristics and chest CT imaging characteristics of patients with confirmed COVID-19 (COVID-19) and patients with suspected COVID-19. Methods: The study time span was from February 2020 to May 2020. The case samples were selected from 72 patients with confirmed covid-19 and suspected covid-19 diagnosed and treated by The First People’s Hospital of Yinchuan and Yinchuan Temporary Emergency Hospital, including 38 patients with confirmed covid-19 and 34 patients with suspected covid-19. All patients underwent laboratory examination and chest CT examination, and the specific examination results were compared and analyzed. Results: There were significant differences in number of white blood cell, percentage of lymphocytes, creatine kinase and erythrocyte sedimentation rate between confirmed and suspected COVID-19 patients (P<0.05). The CT imaging characteristics of COVID-19 patients were compared with those of suspected COVID-19 patients. The lesions of COVID-19 patients were mostly characterized by mixed ground glass density and pure ground glass density. There were vascular thickening and interstitial thickness increase, and accompanied by bronchiectasis or air bronchogram. The distribution of lesions was mostly subpleural without pleural effusion. The lesion area of suspected COVID-19 patients mostly showed solid density and mixed ground glass density. The lesion was distributed along bronchovascular and pleural effusion was observed. Conclusion: There are some differences in biochemical indexes and chest CT images between confirmed and suspected covid-19 patients, which can be used for differential diagnosis.
Objective: To evaluate the efficacy of transbronchoscopic large volume lung lavage in the treatment of pneumoconiosis complicated with chronic obstructive pulmonary disease (COPD). Methods: The clinical data of 80 patients with pneumoconiosis complicated with COPD admitted to our hospital from June 2017 to January 2019 were retrospectively analyzed. 40 patients in the control group were treated with conventional drugs and 40 patients in the observation group treated with conventional drugs plus transbronchoscopic large-volume lung lavage. Dyspnea score and healthy quality of life were compared between the two groups. Results: the scores of dyspnea in the observation group were significantly lower than those in the control group at 12, 24 and 48 weeks after treatment, and the (SGRQ) scores of George's respiratory problems questionnaire in the observation group were significantly lower than those in the control group at 12, 24 and 48 weeks after treatment. Conclusion: Thetransbronchoscopic large volume of lung lavage has a significant effect on the treatment of pneumoconiosis patients with COPD, which can effectively reduce the degree of dyspnea and improve the quality of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
