Objective:This study implemented a pulmonary rehabilitation integrated care management model based on an Internet of things platform for patients with chronic obstructive pulmonary disease (COPD) and evaluated its effectiveness to provide evidence for clinical respiratory rehabilitation practices.Methods:A quasi-experimental design was adopted. Patients from the Department of Respiratory and Critical Care Medicine at Changsha Central Hospital Affiliated to University of South China between May and December 2023 were selected via purposive sampling. Sixty COPD patients from May to August 2023 were assigned to the control group, while 60 patients from September to December 2023 were assigned to the comprehensive management group. The control group adopted routine respiratory rehabilitation management, the comprehensive management group adopted a pulmonary rehabilitation integarted care management mode based on Internet of things platform respiratory rehabilitation. Before and after 6 months of intervention, patients were assessed for respiratory rehabilitation compliance, lung function (including the percentage of forced expiratory volume in the first second to the expected value (FEV 1% pred) and the ratio of forced expiratory volume in the first second to forced vital capacity (FEV 1/FVC), 6-minute walk test (6MWT) and COPD Assessment Test (CAT). Results:Finally, 55 cases were included in the control group and 59 cases were included in the comprehensive management group. The control group included 32 males and 23 females, aged (67.31 ± 7.14) years. The comprehensive management group included 39 males and 20 females, aged (68.15 ± 6.34) years. The respiratory rehabilitation compliance score, FEV 1% pred, FEV 1/FVC, 6MWT, and CAT score of the full management group after intervention were as follows: (26.45 ± 1.51) points, (59.21 ± 6.68)%, (78.35 ± 8.01)%, (479.63 ± 54.70) m, and (12.35 ± 4.01) points, which were all better than the control group′s (15.68 ± 1.56) points, (44.09 ± 6.31)%, (68.38 ± 6.43)%, (429.82 ± 60.50) m, and (17.03 ± 4.23) points. The difference between two groups were significant ( t values were 1.83-5.24, all P<0.05). Conclusions:The pulmonary rehabilitation integarted care management model based on Internet of things platform improves patient compliance, enhances pulmonary function, enhance their activity endurance, and improve their quality of life. It is worth promoting and using in clinical practice.

Objective:To analyze the current situation and influencing factors of information need for cardiac rehabilitation of urban and rural patients with coronary heart disease, and explore the inequality of information need for cardiac rehabilitation among urban and rural patients with coronary heart disease and its influencing factors, so as to provide a scientific reference for formulating targeted cardiac rehabilitation programs.Methods:From June to July 2024, hospitalized patients with coronary heart disease from a Class A tertiary hospital in Suzhou City were selected by convenience sampling as the study subjects. A General Information Questionnaire, Information Need in Cardiac Rehabilitation Hospital Anxiety and Depression Scale, Health Literacy Management Scale, and Coronary Artery Disease Self-Management Scale were used to conduct a questionnaire survey. Multiple linear regression was used to analyze the influencing factors of the cardiac rehabilitation information needs and the oaxaca-blinder model was used to analyze the causes of unequal information needs in urban and rural patients.Results:A total of 254 hospitalized patients with coronary heart disease who met the inclusion and exclusion criteria were surveyed, included 127 males and 127 females, 182 of them were aged 60 years or older. The total cardiac rehabilitation information needs score of rural and urban patients with coronary heart disease were 168.00 (115.50, 255.00) and 213.00 (132.00, 255.00), respectively, the difference was significant ( U = 5 389.50, P<0.05). Multiple regression analysis showed that health literacy ( β = 0.871, P<0.05) was the influencing factor of cardiac rehabilitation information needs of rural coronary heart disease patients, and depression ( β = 0.719, P<0.05) and living status ( β = -0.186, P<0.05) was the influencing factor of cardiac rehabilitation information needs of urban coronary heart disease patients. Average monthly household income per capita (C = 14.50%) and health literacy (C = 88.30%) were the main causes of the difference in cardiac rehabilitation information needs between urban and rural patients with coronary heart disease. Conclusions:The information demand for cardiac rehabilitation of patients with coronary heart disease in rural area is lower than that in urban areas in Suzhou, mainly due to health literacy and monthly income. It is recommended to narrow the urban-rural gap by improving rural health literacy, optimizing medical insurance policies, and promoting a multi-level rehabilitation service network.

ObjectiveTo understand the mortality trends among residents of Fuling District， Chongqing， before and after theCOVID-19 outbreak， and to provide references for the government to formulate disease prevention and control policies and measures. MethodsData on mortality and population in Fuling District from 2017 to 2022 were collected to analyze population mortality and standardized mortality rates， and to compare the changes in the causes of death by year and before and after the pandemic. ResultsFrom 2017 to 2022， the crude mortality rate in Fuling District showed an upward trend （APC=3.04%， P<0.05）， while the standardized mortality rate showed a downward trend （APC=-6.47%， P<0.01）. The mortality rate of males was higher than that of females （P<0.05）， with different age groups having different causes of death composition. The highest proportion of deaths in 0-year-old group was from infectious diseases， maternal and neonatal diseases， and nutritional deficiencies， the highest proportion of deaths in the 1‒24 age group， with the exception of those aged 5‒9， was from injuries， and the main cause of death for residents aged 25 and above was chronic diseases. The mortality rate of mental and behavioral disorders rose from the 13th to the 9th place. According to the epidemic situation of COVID-19， there were no changes in the top five causes of death among the entire population. The motility rate of endocrine， nutritional and metabolic diseases rose from the sixth to the fifth place in male population， and the motility rate of malignant tumor rose from the 3rd to the 2nd place in female population. ConclusionThere are no changes in the top five causes of death among the entire population of Fuling District before and after the COVID-19 outbreak. Chronic diseases remain the main cause of death. It is necessary to control the risk factors for cardiovascular and cerebrovascular diseases such as hypertension， diabetes， and dyslipidemia， and to curb the rising trend of mortality rates from strokes and acute myocardial infarction. For deaths caused by accidental injuries， targeted health education should be conducted for different populations.

Objective:To investigate the association between plasma anti-Müllerian hormone(AMH) levels and ischemic stroke.Methods:In this case-control study, 93 ischemic stroke patients were randomly selected as the case group from a study on the prevention and treatment of metabolic syndrome, which was conducted in 2018-2019 in Changshu, Jiangsu Province, while 372 nonischemic stroke patients were selected as the control group according to the principle of 1∶4 matching.An enzyme-linked immunosorbent assay was used to measure plasma AMH levels.The conditional logistic regression model and restricted cubic spline were used to analyze the relationship between AMH levels and ischemic stroke.Results:A total of 465 subjects with an average age of (68.7±7.4)years were included in this study, of whom 215(46.2%)were men and 250(53.8%)were women.According to our conditional Logistic regression analysis, the risk of ischemic stroke was reduced by 44% for every unit increase in the log-AMH level( OR=0.56, 95% CI: 0.37-0.85)in the overall population after multivariate adjustment.Compared with the tertile with the lowest AMH level, the risk of ischemic stroke in the tertile with the highest AMH level decreased significantly( OR=0.37, 95% CI: 0.19-0.69). When subgrouped by sex, the tertiles with the highest AMH levels were associated with a 66% lower risk of ischemic stroke in men( OR=0.34, 95% CI: 0.13-0.88)and a 64% lower risk of ischemic stroke in women( OR=0.36, 95% CI: 0.15-0.87), compared with the tertiles with the lowest AMH levels.The results of restricted cubic spline analysis showed that there was a linear dose-response relationship between plasma AMH levels and ischemic stroke both in the general population and in male or female population( Pvalues for linear trends were 0.0002, 0.008 and 0.007, respectively). Conclusions:Higher plasma AMH levels decrease the risk of ischemic stroke with a dose-response pattern.

Objective:To examines the social health status and influencing factors affecting the elderly population in urban communities of Beijing, based on the "the Standard for Healthy Chinese Older Adults(2022)" .Methods:Using the stratified sampling method, a total of 159 elderly individuals aged 60 and above from the Lanyuan community in the Malianwa street jurisdiction of Haidian district, Beijing, were selected as research subjects.The average age of the participants was(70.7±7.9)years, comprising 74 males and 85 females.Household face-to-face interviews were conducted, utilizing self-compiled questionnaires to perform a comprehensive assessment and analysis of the social health status of the elderly.Results:In the study involving community-based elderly participants, 32.1%(51 cases)were classified as healthy.The analysis revealed statistically significant differences in the social health status among various age groups of the elderly( χ2=11.802, P=0.019), with a notable downward trend in social health status as age increases( χ2=9.626, P=0.002).Furthermore, the results of multivariate Logistic regression analysis indicated that educational level( OR=2.119, 95% CI: 1.044-4.031, P=0.038)and chronic disease status( OR=5.007, 95% CI: 1.083-23.140, P=0.039)are significant influencing factors on the social health status of older adults. Conclusions:The social health status of the elderly in urban communities in Beijing is generally low and deteriorates progressively with age.Both educational attainment and chronic disease prevalence significantly influence the social health of this demographic.For elderly individuals with lower educational levels and poor chronic disease management, it is essential to conduct social health assessments and implement targeted intervention strategies to enhance their overall social health.

Objective To study the effects of intramedullary pressure on the fluid flow behavior in bones.Methods Multi-scale models of macro bone tissue and macro-meso osteon groups were established using the COMSOL Multiphysics software.Considering the interrelationship of different pore scales,such as the bone marrow cavity,Haversia canal,and bone lacunar-canaliculus,the pore pressure and flow rate of hollow bone tissues and bone tissues with intramedullary pressure were compared,and the effects of the amplitude and frequency of intramedullary pressure on the pressure and flow velocity of the liquid in the bone were analyzed.Results When intramedullary pressure was considered,the pore pressure in bone tissues with intramedullary pressure was 6.4 kPa higher than that in hollow bone tissues.The flow pressure increased significantly with an increase in the intramedullary pressure amplitude,but the flow velocity remained unchanged.The frequency of intramedullary pressure had little effect on pore pressure and flow velocity.Conclusions The multi-scale pore model established in this study can accurately analyze bone fluid flow behavior.These results are of great significance for an in-depth understanding of force conduction in the bone.
