Background: Short internodes contribute to plant dwarfism, which is exceedingly beneficial for crop production. However, the underlying mechanisms of internode elongation are complicated and have been not fully understood.Results: Here, we report a maize dwarf mutant,dwarf2014(d2014), which displays shortened lower internodes. Map-based cloning revealed that thed2014gene is a novelbr2allele with a splicing variation, resulting in a higher expression ofBR2-T02instead of normalBR2-T01. Then, we found that the internode elongation ind2014/br2exhibited a pattern of inhibition-normality-inhibition (transient for the ear-internode), correspondingly, at the 6-leaf, 12-leaf and 14-leaf stages. Indeed,BR2encodes a P-glycoprotein1 (PGP1) protein that functions in auxin efflux, and our in situ hybridization assay showed thatBR2was mainly expressed in vascular bundles of the node and internode. Furthermore, significantly higher auxin concentration was detected in the stem apex ofd2014at the 6-leaf stage and strictly in the node region for the ear-internode at the 14-leaf stage. In such context, we propose that BR2/PGP1 transports auxin from node to internode through the vascular bundles, and excessive auxin accumulation in the node (immediately next to the intercalary meristem) region suppresses internode elongation ofd2014.Conclusions: These findings suggest that low auxin levels mediated by BR2/PGP1 in the intercalary meristem region are crucial for internode elongation.

Aim: This study aimed to describe and visualize the current research state and collaborative networks in home care safety for older adults over the past 11 years to analyse the gaps of research and future research trends.Background: The amount of research on safety in home care for older adults is increasing. It is necessary to understand the status of development and main research topics and identify the main contributors and their relationships.Methods: A total of 2,631 publications were retrieved from the Web of Science. The external characteristics of the publications were summarized with the Web of Science and Histcite. Collaborative networks and keywords were analysed and visually displayed using analysis tools.Results: The number of articles increased over the years. Articles were identified from 79 countries, 3,630 institutions, 647 journals and 11,691 authors, and complex cooperative relations among them and five research topics were identified.Conclusion: Research on home care safety for older adults is developing steadily, and this field may be understood to a greater extent in the future. Countries, institutions and scholars need to cooperate more in this research field.Implications for Nursing Management: This study contributes important information for understanding achievements in the research field of home care safety and provides insights into future research.

Objectives: This study aimed to measure the patient safety culture and the current practice of patient safety goals in China. Methods: This cross-sectional survey was conducted between November 2020 and November 2021. The 12-dimensions Hospital Survey on Patient Safety Culture questionnaire and the 14-items Survey on the Current Practice of Patient Safety Goal questionnaire were electronically distributed to 8164 healthcare providers across 26 provinces in China. Data were analyzed using descriptive statistics, correlation analysis, and multivariate linear regression. Results: A total of 8164 surveys were received, of which 7765 were valid and analyzed. The average positive response rate for the Hospital Survey on Patient Safety Culture survey was 69.68% (43.41%–91.54%). The percentage of positive responses in 5 dimensions (organizational learning, teamwork within units, feedback about error, management support for safety, and teamwork across units) was above the control limits, and 3 (nonpunitive response to error, staffing, and frequency of event reporting) were below the control limits. The average positive response rate for the Survey on the Current Practice of Patient Safety Goal survey was 96.11%. Patient safety culture was positively related to the current practice of patient safety goals (r = 0.34, P < 0.001). Conclusions: Our study concludes that although healthcare providers in China feel positively toward patient safety culture and practicably toward patient safety goals, considerable work is still needed to promote a patient safety movement.

Objective: To explore the Chinese community-dwelling intention of older adults to adopt gerontechnology and its influencing factors.Design: A mixed-methods sequential explanatory design with an inductive approach was employed. In phase 1, a self-made questionnaire was administered from August 2018 to December 2019. Multifactor logistic regression was used to analyze the adoption intention and factors influencing the use of gerontechnology. In phase 2, participants completed a semistructured interview to explore the adoption intention of a specific form of gerontechnology, Smart Aged Care Platform, from May to July 2020.Setting: Twelve communities in three districts of Chongqing, China.Participants: Community-dwelling older adults were included.Results: A total of 1,180 older adults completed the quantitative study; two-thirds of them (68.7%) showed adoption intention toward gerontechnology. Nineteen participants (10 users and nine nonusers) completed the qualitative study and four themes were explored. Through a summarized understanding of the qualitative and quantitative data, a conceptual model of influencing factors, namely, predictive, enabling, and need factors, was constructed.Conclusions: This study reveals that most Chinese community-dwelling older adults welcome the emergence of new technologies. However, there was a significant difference in the adoption intention of gerontechnology in Chinese community-dwelling older adults based on their sociodemographic and psychographic characteristics. Our findings extend previous technology acceptance models and theories and contribute to the existing resource base.

Aim: To the determinants and the underlying mechanism of health literacy, social support, and resilience on the health‐related quality of life (HRQoL) among older stroke survivors.Design: A cross‐sectional design was applied at four comprehensive hospitals in Chongqing via convenience sampling from January 2020 to June 2021.Methods: Health literacy, social support, and resilience were designed as independent variables, and HRQoL was measured as a dependent variable. Structural equation modelling with the bootstrap method was used to test the hypotheses.Results: The theoretically derived model exhibited a good fit (χ²/df ratio = 2.830, GFI = 0.987, CFI = 0.978, RMSEA = 0.066). Health literacy (β = 0.12, p < 0.05) and social support (β = 0.14, p < 0.05) directly affect HRQoL. Resilience (β = 0.40, p < 0.01) also mediated the relationship between health literacy, social support, and HRQoL. The three variables explaining 29.0% of HRQoL variance.Patient or Public Contribution: There was no direct patient or public involvement in the design, conduct, or reporting of this study. Participants were recruited through convenience sampling from four comprehensive hospitals in Chongqing, and their perspectives or contributions were not explicitly sought. The study focused on examining the determinants and underlying mechanism of health literacy, social support, and resilience on the health‐related quality of life among older stroke survivors. Nonetheless, the findings of this research may inform the development of interventions aimed at improving the health‐related quality of life in post‐stroke older patients.
