ObjectiveTo explore the factors influencing home-based rehabilitation exercise and the needs for digital interventions among patients with spinal muscular atrophy (SMA), based on the behavior change wheel (BCW), and to provide evidence for the development of digital home-based rehabilitation interventions. MethodsA two-phase qualitative study was conducted from December, 2024 to March, 2025. Using convenience sampling, 14 participants were recruited, including patients with SMA, primary caregivers, rehabilitation professionals, clinicians, a patient organization representative and a health policy expert. In phase 1, semi-structured individual interviews were conducted with seven participants, including patients, caregivers and a patient organization representative, to identify factors influencing home-based rehabilitation exercise and unmet needs. In phase 2, a focus group involving 12 stakeholders was conducted, including five participants who had participated in phase 1, to explore requirements for the functions, knowledge content and interface design of a digital intervention, five of them had participated in phase 1. Overall, the two phases involved 14 individual participants, accounting for 19 participant-instances. Thematic analysis was performed using both deductive and inductive approaches, guided by the capability-opportunity-motivation-behavior (COM-B) model. ResultsSix themes were identified. phase 1 showed that patients with SMA experienced inadequate continuity of rehabilitation services and limited access to professional rehabilitation resources, with interruptions in institution-based rehabilitation coexisting with declining adherence to home-based exercise. Home-based rehabilitation exercise was jointly influenced by capability-, opportunity- and motivation-related factors, including limited capabilities of patients and caregivers, constraints in time and supportive conditions and insufficient goals, feedback, and incentives. Individualized rehabilitation plans and professional guidance were the major unmet needs. phase 2 showed that the core functions of a digital intervention should include individualized exercise plans, professional guidance and feedback, reminders and incentives, safety monitoring, remote assessment, and privacy and permission management. Core knowledge content should include stratified exercise guidance, caregiving skills, recognition of abnormal conditions, and information on when and how to seek help. The interface should be simple, impose a low user burden and accommodate different types of users. ConclusionHome-based rehabilitation exercise among patients with SMA is jointly influenced by multiple capability-, opportunity- and motivation-related factors. Digital interventions should prioritize individualized rehabilitation plans, professional guidance and sustained behavioral support. These findings may inform the development of a digital home-based rehabilitation intervention prototype for patients with SMA; its feasibility, safety, clinical effectiveness and economic value require further evaluation.

Objective:To study the epidemic and etiologic characteristics of influenza virus(Flu)and respiratory syncytial virus (RSV) infections in outpatient influenza-like illness(ILI)cases of children under 10 years of age in Gansu province in 2018 And to provide evidences for diagnosis, treatment, control and prevention of Flu and RSV infections in Gansu province.Methods:A total of 8 559 pharyngeal swab samples of ILI outpatients cases were tested with real-time fluorescent PCR to detect Flu, 3 436 of which were detected by RT-PCR for RSV.Results:Of the 8559 specimens, 934 (10.91%) samples were positive for Flu. Among them, 431 were positive for H1N1, 70 were positive for H3N2, 428 were positive for Flu B, 5 were mixed; 320 of the 3436 (9.31%, ) samples were positive for RSV. There were significant differences in the positive rates of Flu and RSV among 14 cities and prefectures ( χ2=56.99, χ2=263.34, Р< 0.01). Influenza reached its peak in January 2018 with a positive rate of 50.70%. Flu B/Yamagata strain (53.53%) and A H1N1 (39.93%) were prevalent simultaneously. The peak of RSV epidemic was from February to April, the positive rate was 13.98%. The RSV positive rate of children under 5 years of age was 10.11%, higher than that of children over 5 years of age was 6.94%. There was statistical significance ( χ2=7.67, Р<0.01). Conclusions:RSV and influenza viruses are the main pathogens in ILI cases of children under 10 years of age. There are epidemic peaks in winter and spring every year. It is suggested that the monitoring of RSV and the development and application of vaccine should be strengthened.

Objective To investigate the effects of Xiao Yao San on intracellular Ca2 + concentration in cultured rat hippocampal neurons in the state of chronic stress and study the mechanism of chronic stress injuring and XiaoYao San protecting. Methods MK-801 acts as tool,cultured rat hippocampal neurons were divided into seven groups, those were group 1 (control), group 2 (normal serum), group 3 (normal serum + Glu), group 4 (model serum + Glu), group 5 (model serum + Glu + MK-801), group 6 (Xiaoyaosan + Glu), group 7 (Xiaoyaosan + Glu + MK-801). to detect intracellular Ca2+ concentration in cultured hippocampal neurons in the simulated micro - environment of chronic stress and after intervention with the serum treated with Xiao Yao San by confocal laser microscope at the same period of time. Results Compared with group 1 (779.97 ± 36.81), concentration of Ca2+ intracellular of group 2 (1092.38 ± 36.41), group 3 (1472.49 ± 76. 19), group 4 (1509.52 ±104.69) and group 5 (1186.97 ±41.92) all increased significantly (P＜0.01) ,group 6 (908.74 ±40.24) increased too (P ＜ 0.05), compared with group 2, concentration of Ca2 + intracellular of group 3,4 and 5 all increased significantly (P ＜ 0.01), but group 7 (721.99 ± 60.33) decreased significantly (P ＜ 0.01). Compared with group 4, concentration of Ca2+ intracellular of group 6 and 7 decreased significantly (P＜ 0.01), group 5 decreased too (P ＜ 0.05), compared with group 6, concentration of Ca2 + intracellular of group 5 increased significantly (P ＜ 0.01),when group 7 decreased significantly (P＜0.01). Conclusion Serum of chronic stress treated with Xiao Yao San has the effect of inhibiting Ca2+ overload in hippocampal neurons,it may work through a variety of signaling pathways including Glu-NR-Ca2+ to maintain the steady-state of Ca2+ concentration in hippocampal neurons, and then to protect neurons from the neurotoxic effects of excitatory.

Objective To observe the mechanisms that Xiaoyao powder influences the hypothalamus-pituitary-adrenal (HPA) axis of chronic-stress rats. Methods Chronic stress rats were as researching object,and RU-38486 acted as tool drugs. The serum-GC density of rats were tested with ELISA,and the glucocortcoid(GR) in hippocampus neuron were tested with immunofluorescence,the CRH mRNA in hypothalamus were tested by in situ hybridization (ISH). Results Compared with normal group ( 1.09 ± 0.11 ;0.57 ± 0.10), the expression of GR in hippocampus of model group decreased(0.65 ± 0. 10; P ＜ 0. 01 ), and the expression of CRH mRNA in hypothalamus of model group increased ( 1.12 ±0. 11; P＜0. 0l ) ,the GR in hippocampus of RU-38486 group increased ( 1.59 ± 0. 11; P ＜ 0. 01 ), and the expression of CRH mRNA in hypothalamus of RU-38486 group reduced (0.48±0.10; P＜0.05) ,but both the expression of GR in hippocampus and the CRH mRNA in hypothalamus of Xiaoyao powder group were no change (0.62 ±0.08;0.97 ±0.13; P＞0.05). Compared with model group,both the expression of GR in hippocampus of RU-38486 and Xiaoyao powder group increased (P＜0. 01) ,and both the expression of CRH mRNA in hypothalamus of RU-38486 and Xiaoyao powder group reduced (P＜0.01). Conclusion Multi-stress can result in the expression of GR in hippocampus of rats decreasing and the expression of CRH mRNA in hypothalamus increasing, but those changes can be restrained by Xiaoyao powder, and it is the maybe mechanism of Xiaoyao Powder resisting chronic stress in HPA axis.
