ABSTRACT
Objective:To analyze the related literature of pulmonary rehabilitation research at home and abroad, understand its research focus and development trend, and provide a reference and basis for future pulmonary rehabilitation research.Methods:Literature related to pulmonary rehabilitation published in the database of Web of Science and China National Knowledge Infrastructure from January 2015 to February 2022 was retrieved, and the contents such as the number of articles published annually, authors, research institutions, and high-frequency keywords were visually analyzed by bibliometrics and CiteSpace software.Results:The number of articles published each year showed an obvious upward trend from 2015, and the number of Chinese documents was higher than that of English documents from 2019 to 2020. MARTIJN A SPRUIT was the author with the largest number of articles published in English, with a total of 65 articles published, with close cooperation among scholars. Che Guowei was the author with the largest number of articles published in Chinese literature, with 13 articles published in total. The cooperation among the authors was relatively lacking and scattered. The main research institutions abroad were universities, and the institution with the highest number of papers was Maastricht University in the Netherlands, with a total of 85 articles. The research institutions cooperated closely and formed a cooperation network. Hospitals were the main research institutions in China, and the thoracic surgery Department of West China Hospital of Sichuan University had the highest total number of publications, with 14 articles. The cooperation among institutions was not close, and there was a lack of cooperation with universities and scientific research institutions. Through keyword co-occurrence and clustering and timeline view analysis, it was concluded that the research hotspots in this field were pulmonary rehabilitation of patients with different chronic respiratory diseases, the influence of pulmonary rehabilitation on lung function and quality of life of patients with chronic obstructive pulmonary disease, and the intervention methods of pulmonary rehabilitation. The future trend was predicted as the clinical application value of pulmonary rehabilitation in the treatment of lung cancer.Conclusions:At present, pulmonary rehabilitation research is in a stable development period. However, the cooperation between domestic authors and institutions is not close enough compared with foreign countries. In the future, China should strengthen the communication and cooperation between research teams, and learn from foreign research results to further develop the application of pulmonary rehabilitation in lung cancer patients, to promote the development of pulmonary rehabilitation research in China.
ABSTRACT
Objective:To analyze the characteristics of child cases admitted to accidental injury and provide reliable basis for the prevention of accidental injury.Methods:The clinical data of children admitted to Hunan Children′s Hospital aged 0-18 due to accidental injuries from January 1, 2018 to December 31, 2021 were retrospectively analyzed. The type of accidental injury and characteristic factors such as prognosis, gender, age, time, and location of the child were analyzed.Results:A total of 9 049 children with accidental injury were admitted, accounting for 3.72%(9 049/33 697) of the total number of hospitalized children. The top three types of accidental injuries were falls/drop (3 695 cases), foreign bodies/suffocation (2 639 cases) and traffic accidents (1 165 cases), accounting for 82.87%(7 499/9 049). There were 8 760 cases (96.81%) of improvement and recovery, 178 cases (1.97%) of disability, and 111 cases (1.23%) of unhealed/dead. Among the accidental injuries, 5 833 cases (64.46%) were boys and 3 216 cases (35.54%) were girls, and the incidence ratio was 1.81∶1. There was significant difference between boys and girls in the composition ratio of the type of accidental injury such as falls/falls, foreign bodies/suffocation, poisoning, sharp object injury, drowning ( χ2 values were 3.90-20.56, all P<0.05). Among the accidental injuries, the children aged 1 to<3 years had higher accidental injuries than the other age groups (3 263 cases, accounting for 36.06%), and the composition ratio of accidental injuries in different age groups was different ( χ2 values were 12.98-573.97, all P<0.05). Among the accidental injuries, the accidental injuries occurred in the second quarter and the third quarter were higher than those in the other two quarters (4 892 cases, accounting for 54.06%), and the composition ratio of accidental injuries such as falls/falls, foreign bodies/suffocation, burn and scald, drowning occurred in different quarters was different ( χ2 values were 10.79-18.88, all P<0.05). In the case of accidental injuries, the family was the most likely place of accidental injury, with different types of accidental injuries occurring in different places ( χ2 values were 10.08-2 186.54, all P<0.05). Conclusions:Children′s unintentional injuries are most likely to occur in boys aged 1-<3 years, and fall/fall is the main injury type. Traffic accidents are the most important unintentional injury type leading to children′s unhealed/dead. Different injury types were related to child gender, age, quarter, and place of occurrence.Due to the differences in the occurrence mechanism and injury mode of accidental injuries in different countries and regions, and the majority of accidental injuries can be prevented, targeted preventive measures should be taken according to the characteristics of children′s accidental injuries in different regions, and a comprehensive prevention system for children′s accidental injuries should be constructed to ensure children′s safety.
