With Minglou Community Children's Rehabilitation Base as a case,which was jointly founded by tertiary specialized hospital and community health service center,the paper introduced how to use SWOT model to systematically analyze the strengths and weaknesses of the internal environment,opportunities and threats of external condition.Based on the analysis,the solutions,suggestions and policy of children's rehabilitation were proposed,providing reference for decision making to promote the community children's rehabilitation.

Objective:To investigate the effects of cardiac exercise rehabilitation on heart failure with preserved ejection fraction.Methods:200 patients with clinically diagnosed heart failure with preserved ejection fraction who received treatment from May to December 2019 were included in this study. They were randomly assigned to receive either routine treatment (control group, n = 100) or routine treatment combined with cardiac exercise rehabilitation (observation group, n = 100). Before and after treatment, the distance walked during the 6-minute walk test was compared between the control and observation groups. Before and after treatment, plasma level of brain natriuretic peptide, left ventricular ejection fraction, left ventricular short-axis fractional shortening, left atrial diameter, left ventricular end diastolic diameter were compared between the two groups. Adverse events such as falls during treatment were recorded in each group. Before and after treatment, quality of life was evaluated using The Minnesota Living With Heart Failure Questionnaire in each group. All patients were followed up for 3 months. Three-month rehospitalization rate was calculated in each group. Results:After treatment, the distance walked during the 6-minute walk test in the observation group was significantly longer than that in the control group [(421.63 ± 86.75) m vs. (328.44 ± 74.93) m, t = 8.130, P < 0.001). After treatment, the distance walked during the 6-minute walk test in each group was significantly increased compared with before treatment ( tcontrol group = 6.584, P < 0.001; tobservation group = 15.337, P < 0.001). After treatment, plasma level of brain natriuretic peptide in the observation group was significantly lower than that in the control group [(227.68 ± 31.22) mg/L vs. (269.74 ± 36.81) mg/L, t = 8.714, P < 0.001]. After treatment, plasma level of brain natriuretic peptide in each group was significantly decreased compared with before treatment ( tcontrol group = 24.669, P < 0.001; tobservation group = 38.776, P < 0.001). After treatment, left ventricular end diastolic diameter and left atrial diameter in each group were significantly decreased compared with before treatment ( t = 4.031, 10.166, 3.715 and 12.569, all P < 0.05), while left ventricular ejection fraction and left ventricular short-axis fractional shortening in each group were significantly increased compared with before treatment ( t = 7.610, 11.906, 3.915 and 6.105, all P < 0.05). The amplitude of improvement in abovementioned indices in the observation group was significantly greater than that in the control group ( t = 7.255, 12.739, 4.703 and 2.442, all P < 0.05). During the treatment, no falls, adverse cardiovascular events, or death occurred in each group. After treatment, the Minnesota Living With Heart Failure Questionnaire scores in physical domain, emotional domain and other domains in the observation group were (23.96 ± 4.75) points, (9.47 ± 2.02) points, (26.31 ± 1.84) points, respectively, which were significantly lower than those in the control group [(28.63 ± 5.12) points, (12.35 ± 1.89) points and (32.76 ± 2.49) points, t = 6.867, 10.411 and 20.833, all P < 0.001]. After treatment, the Minnesota Living With Heart Failure Questionnaire scores in various domains in each group were significantly decreased compared with before treatment ( t = 6.648, 14.746, 28.782, 35.262, 9.665 and 27.962, all P < 0.05). Three-month rehospitalization rate in the observation group was significantly lower than that in the control group [10.0% (10/100) vs. 22.0% (22/100), χ2 = 5.357, P = 0.021]. Conclusion:Cardiac exercise rehabilitation for the treatment of heart failure with preserved ejection fraction can help improve the heart function, increase exercise endurance, improve prognosis, reduce rehospitalization rate, and improve quality of life.

Objective: To propose the concept of a novel regional control and prevention (RCP) system for the outbreak of COVID-19 infectious disease, design an emergency epidemic prevention information system based on the existing network architecture and information system in the region, and a remote intelligent medical consultation and remote office platform, research and develop the technology of risk assessment and early warning for people in the region, and improve the regions’prevention and control ability facing emergency of major infectious diseases. Methods: Taking colleges, affiliated (teaching) hospitals, and cloud applications as typical RCP regional units, the existing local area network interaction methods between the cloud and universities and affiliated (teaching) hospitals are established to realize remote work in the network environment, remote medical imaging, psychological and ethical consultation and interaction; applying multi-agent propagation model based on complex network, combining Global Positioning System (GPS), Radio Frequency Identification (RFID), and electronic fence technology, to realize the risk classification and early warning of units and personnel in the area. Results: In the RCP, a system architecture combining campus network, affiliated (teaching) hospital intranet, and the Internet is used. Dynamic connection is made using distributed technology and cloud storage. The data buffer mechanism of the intermediary database in the network realized telemedicine consultation and telecommuting. Relying on the platform, multi-agent propagation model based on complex network and cellular automaton model are used to realize the score and early warning of population exposure risk in the region by using GPS, RFID and electronic fence technology. Conclusions In the epidemic phase of major infectious diseases, the construction of RCP can improve the response speed of wartime epidemic prevention, provide reasonable data-based warnings and risk ratings, and reduce the exposure risk of susceptible people. The design and development of RCP is a systematic project that needs to combine regional structural and functional characteristics, and the foundation of the early informatization work in the region and the level of the emergency development team determine the development progress, maintenance, and actual application effects. It is recommended to establish a peacetime and wartime combined RCP mode and incorporate it into the government's disease control system to improve the national and regional level of prevention and control of major infectious diseases.
