Background: Metals and their ions have been used to reduce bacterial infection risks. Among them, minerals containing rubidium (MCR), natural minerals containing metal ions, show potential as novel and tunable materials. Objective: This study aimed to investigate the antibacterial activity and mechanism of MCR. Methods: The inhibitory effect of MCR on bacteria was clarified using the growth curve method, turbidimetric method, and minimum inhibitory concentration method. Physiological and biochemical indices were employed to investigate the inhibitory mechanism of MCR. Results: The results revealed that MCR inhibited Staphylococcus aureus, Listeria monocytogenes, and Escherichia coli with minimum inhibitory concentrations of 11.95, 2.60, and 2.60 mg/mL, respectively. The inhibitory activity of MCR was insignificant against Bacillus subtilis, Salmonella typhimurium, and Helicobacter pylori at 3.25 mg/mL. Mechanistic assessments showed that MCR affected bacterial conductivity, protein and nucleic acid levels, reducing sugar content, respiratory chain dehydrogenase activity, bacterial lipid peroxidation, intracellular adenosine triphosphate, and extracellular alkaline phosphatase. Conclusion: MCR has bacteriostatic activity and the mechanism primarily involves adhesion to bacteria, disrupting the integrity of their cell walls and membranes, and altering their permeability. This disruption leads to the release of intracellular molecules of various sizes, inhibiting cellular respiration and metabolism, and causing oxidative damage. These combined effects impair cellular functions, affecting cell growth and metabolism, or leading to cell death. These findings provide a theoretical reference for the development of MCR as a bacteriostatic agent.

BACKGROUND:
As an essential part of health services, rehabilitation is of great significance to improve the health and quality of life of the whole population. Accelerating aging calls for a significant expansion of rehabilitation services in China, but rehabilitation needs remain unclear. We conducted the study to explore the rehabilitation needs in China and project the trend of rehabilitation needs from 2020 to 2034.
METHODS:
The data of health conditions that might potentially benefit from rehabilitation were obtained from Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of rehabilitation needs were made until 2034 using Bayesian age-period-cohort analysis (BAPC).
RESULTS:
Approximately 460 million persons (33.3% of the total population) need rehabilitation in China, contributing to 63 million years lived with disabilities (YLDs) in 2019. The number of prevalent cases that need rehabilitation increased from around 268 (95% uncertainty interval [UI]: 257-282) million in 1990 to almost 460 (95% UI: 443-479) million in 2019, representing an increase of 71.3%. The highest contribution to the need for rehabilitation was musculoskeletal disorders with about 322 (95% UI: 302-343) million persons in seven aggregate disease and injury categories, and hearing loss with over 95 (95% UI: 84-107) million people among 25 health conditions. Based on the projection results, there will be almost 636 million people (45% of the total population) needing rehabilitation services in China by 2034, representing an increase of 38.3%. The rehabilitation needs of neoplasms, cardiovascular diseases, and neurological disorders are expected to increase significantly from 2019 to 2034, with increases of 102.3%, 88.8% and 73.2%, respectively.
CONCLUSIONS
The need for rehabilitation in China substantially increased over the last 30 years. It is predicted that over two in five people will require rehabilitation by 2034, thus suggesting the need to develop rehabilitation services that meet individuals' rehabilitation needs.

Objective:To investigate the chain mediating role of psychological resilience and coping styles between social support and psychological distress in elderly stroke patients.Methods:Using convenience sampling, 245 elderly stroke patients with their first episode, admitted to the Neurology Department of the Affiliated Hospital of Hebei University from June to July 2023, were recruited as study subjects. A questionnaire survey was conducted using a General Information Questionnaire, Distress Thermometer for Stroke Patients, Perceived Social Support Scale, Connor-Davidson Resilience Scale Short Form, and Medical Coping Modes Questionnaire. Pearson correlation analysis was used to examine the relationships between psychological distress, social support, psychological resilience, and coping styles in elderly stroke patients. Harman's single-factor test was employed to detect common method bias among variables. The PROCESS macro in SPSS software was utilized to test the chain mediation effects.Results:A total of 245 questionnaires were distributed, with 230 valid responses collected, yielding a response rate of 93.9%. Among the 230 elderly stroke patients, the incidence of psychological distress was 23.9% (55/230). Significant correlations were observed among psychological distress, social support, psychological resilience, and coping styles ( P<0.05). Social support influenced psychological distress through the mediation of psychological resilience and confrontational coping, with a total indirect effect of -0.098. The same relationship existed for social support through psychological resilience and avoidant coping, with a total indirect effect of -0.058. Additionally, social support influenced psychological distress through psychological resilience and submissive coping, with a total indirect effect of -0.113. Avoidant coping had a suppressing effect on the influence of social support on psychological distress. Conclusions:Elderly stroke patients experienced moderate to low levels of psychological distress. Psychological resilience and coping styles played a chain-mediating role between social support and psychological distress. Special attention should be given to elderly stroke patients with low levels of social support.
