In recent years, the aging process of China′s population has accelerated, and the number of disabled people has skyrocketed. It is urgent to improve the health benefits of family bed services. The author found that there was a lack of synergy in policies, service subjects and content, and service concepts in the practical process of family bed services in various regions of China, which limited the effectiveness of services. The author put forward the theoretical framework of integrated family bed service, combined the service practice experience of six cities, namely Guangzhou, Shanghai, Beijing, Shenzhen, Nanjing and Hohhot, and put forward specific suggestions on building integrated family bed service. Among them, department collaboration could be the source power of system integration, institutional linkage could improve service continuity, service concept and incentive mechanism could promote each other, and modern technology could promote functional integration.

Objective:To identify the viral etiologies and epidemic characteristics of acute respiratory infection (ARI) in Fuzhou.Methods:The information and respiratory tract specimens of ARI cases from three different types of hospitals in Fuzhou were collected in 2019. Real-time quantitative fluorescent PCR (Polymerase Chain Reaction, PCR) was uesd to detect adenovirus (AdV) and human bocavirus (HBoV), Real-time quantitative fluorescent RT-PCR (Reverse Transcription-PCR, RT-PCR) was used to detect influenza virus A/B (IFV-A/B), respiratory syncytial virus (RSV), parainfluenza virus 1-4 (PIV-1~4), human metapneumovirus (HmpV), coronavirus (CoV)-229E/OC43/HKU1/NL63 and rhinovirus (RV). Chi-square test and Fisher exact test were used to analyze the epidemiological characteristics of ARI cases. Results:Of the 726 ARI cases enrolled, 316 (43.53%) were positive for at least one viral pathogen, of which, 40 cases had dual infection and 9 had triple infection. The viral infection rates in different age groups were significantly different. The main viral pathogens in ARI in Fuzhou in 2019 were IFVs (12.40%), followed by Adv (10.61%), RV (8.82%), and RSV (5.51%). The AdV infection was more common in male ARI cases, and IFV-B, PIV, RSV, RV, and AdV were identified more commonly in children. In addition, the infection with IFVs, RSV, and RV had obvious seasonality.Conclusions:The main pathogens of ARI cases in Fuzhou in 2019 include IFVs, AdV, RV, RSV, etc. The infection of respective virus in ARI cases represent different age-distribution and seasonality.

Objective:This study aimed to assess left atrial function in adults across various age groups using 4-dimensional automated left atrial quantification(4D Auto LAQ)technology.The study also aimed to compare the differences in two-dimensional(2D)and four-dimensional(4D)strains of the left atrium among different age groups, with the goal of enhancing the clinical utility of 4D Auto LAQ.Methods:A total of 409 healthy volunteers were recruited for the research.Two-dimensional and four-dimensional images were obtained using a GE Vivid E95 ultrasound system with a 4Vc four-dimensional probe.The study examined variations in 2D and 4D ultrasound parameters across various age groups.Furthermore, the relationship between left atrial reservoir strain(LASr), Left atrial conduit strain(LAScd), left atrial contraction strain(LASct), and age was explored.Results:The study involved 409 volunteers, with 217 males and 192 females, who were categorized into three age groups: young(18-45 years, n=56), middle-aged(46-65 years, n=202), and elderly(>65 years, n=151).Conventional ultrasound measurements indicated changes in left atrial anterior-posterior diameter with age progression: (31.70±3.65)mm for the young group, (34.02±3.91)mm for the middle-aged group, and(35.2±4.37)mm for the elderly group( P<0.01).The 2D and 4D left atrial parameters across the age groups were as follows: LASr(2D)(%): 37.48±7.51, 30.95±8.23, 26.9±7.56( P<0.01); LA VImax(ml/m 2): 23.54±5.79, 26.33±7.6, 28.99±8.15( P<0.01); LASr(%): 31.2±17.07, 22.5±8.59, 19.49±7.47( P<0.01).Both 2D and 4D left atrial parameters exhibited significant associations with age.Specifically, the correlations between LASr(2D)(%), LAScd(2D)(%), LASr(%), LAScd(%), and age were -0.429, 0.580, -0.354, 0.298, respectively( P<0.01). Conclusions:The 4D Auto LAQ technology is efficient in assessing left atrial function across various age groups, with age playing a significant role in influencing left atrial parameters.When compared to other ultrasound parameters, both 2D and 4D left atrial strain parameters have the ability to detect differences at an early stage, making them suitable for the early screening, evaluation, and monitoring of age-related left atrial dysfunction, especially in the elderly population.
