    Abstract Background: As China's population ages, the demand for care for the disabled elderly is increasing, and family caregivers find it challenging to meet the comprehensive care needs of the disabled elderly. Through home respite services, families of the disabled elderly can receive help and support from specialized nursing professionals to ease the burden on family caregivers and provide high-quality services. This study explores the willingness and influencing factors of Master of Geriatric Nursing Specialist postgraduates in China to volunteer to provide home respite services for disabled elderly individuals.
    Methods: A qualitative study based on Grounded Theory used Strauss and Corbin's programmatic version. A purposive sampling method was employed to conduct semi-structured interviews with 12 Master of Geriatric Nursing Specialist postgraduates from a tertiary hospital in Changsha, Hunan Province, China.
    Results: The willingness of Master of Geriatric Nursing Specialist postgraduates to volunteer to provide home respite services for the disabled elderly was established as a core category, which was influenced by three main categories: personal factors, service object factors, and social factors, and nine categories formed from 39 initial concepts were included under the main category.
    Conclusions: Influenced by China's traditional cultural background, Master of Geriatric Nursing Specialist postgraduates in China have shown high motivation in volunteering to provide home respite services for the families of the disabled elderly but have been challenged by several challenges from China's healthcare environment and education system. Relevant departments need to adopt a series of policies and measures to increase volunteers' willingness to participate in respite care and promote its development.

    Abstract Protein crotonylation plays a role in regulating cellular metabolism, gene expression, and other biological processes. NDUFA9 (NADH dehydrogenase [ubiquinone] 1 alpha subcomplex subunit 9) is closely associated with the activity and function of mitochondrial respiratory chain complex I. Mitochondrial function and respiratory chain are closely related to browning of white adipocytes, it's speculated that NDUFA9 and its crotonylation are associated with browning of white adipocytes. Firstly, the effect of NDUFA9 on white adipose tissue was verified in white fat browning model mice, and it was found that NDUFA9 promoted mitochondrial respiration, thermogenesis, and browning of white adipose tissue. Secondly, in cellular studies, it was discovered that NDUFA9 facilitated browning of white adipocytes by enhancing mitochondrial function, mitochondrial complex I activity, ATP synthesis, and mitochondrial respiration. Again, the level of NDUFA9 crotonylation was increased by treating cells with vorinostat (SAHA)+sodium crotonate (NaCr) and overexpressing NDUFA9, it was found that NDUFA9 crotonylation promoted browning of white adipocytes. Meanwhile, the acetylation level of NDUFA9 was increased by treating cells with SAHA+sodium acetate (NaAc) and overexpressing NDUFA9, the assay revealed that NDUFA9 acetylation inhibited white adipocytes browning. Finally, combined with the competitive relationship between acetylation and crotonylation, it was also demonstrated that NDUFA9 crotonylation promoted browning of white adipocytes. Above results indicate that NDUFA9 and its crotonylation modification promote mitochondrial function, which in turn promotes browning of white adipocytes. This study establishes a theoretical foundation for the management and intervention of obesity, which is crucial in addressing obesity and related medical conditions in the future.
