Perimenopausal depression (PMD) is an affective disorder that occurs in women during the transition from sexual maturity to old age. It can induce various complications, such as insomnia and cognitive decline. The etiology of PMD is complex. Although multiple hypotheses have been proposed, there is still no unified theory that fully explains its pathogenesis. Research into its mechanisms relies heavily on animal experiments, and establishing reliable animal models is crucial for experimental studies. Appropriate animal models can better simulate human pathophysiological states, rapidly evaluate the efficacy and safety of drugs and intervention methods, grasp the essence of the disease, and uncover its intrinsic connections, thereby exploring more advanced intervention strategies. However, there is a lack of systematic review and summarization of literature related to model construction. Additionally, traditional Chinese medicine (TCM), adhering to the principles of ''syndrome differentiation and treatment'' and ''holistic concept'', has shown significant efficacy in treating PMD. In recent years, research exploring and analyzing its therapeutic mechanisms has been increasing. Therefore, to gain a clearer and more comprehensive understanding of PMD animal modeling methods and the mechanisms of TCM, this paper reviewed Chinese and English literature on PMD animal models and mechanisms of TCM in PMD treatment. It summarized the construction methods of single-factor and multi-factor PMD models, and discussed the advantages and disadvantages of each modeling approach. Furthermore, it delved into the mechanisms of TCM intervention in PMD, revealing that TCM formulas primarily exert their effects by regulating the hypothalamic-pituitary-adrenal axis, hypothalamic-pituitary-ovarian axis, gut-brain axis, cell signaling pathways, neural circuits, hormone levels, and neurotransmitter levels. This review aims to provide a reference for future research in this field. In summary, by summarizing the progress in the methods for PMD animal model construction and the mechanisms of TCM, the paper seeks to offer new insights into the mechanistic research of TCM intervention in PMD.

Objective:To gain an in-depth understanding of the career development of male nurses in China, analyze trends, challenges, and opportunities, and provide a basis for policy-making, talent cultivation, and professional development in the nursing field.Methods:A descriptive qualitative research method was adopted. From March 29th to July 30th, 2023, the heads of the male nurses working groups of nursing associations in 26 regions of China were selected by purposive sampling method for semi-structured interviews. Content analysis was used to analyze the data.Results:The current situation of the career development of male nurses in China could be summarized into the following three themes. (1) Current situation: the organizational structure of provincial-level male nurses work was basically complete, but there were obvious differences at the grassroots level; the work was carried out in various forms, and diverse models developed in coordination; (2) Trends: there were obvious stratifications in professional ideology and professional abilities of male nurses among different regions and different-level medical institutions; the gender dividend was gradually decreasing, and male nurses should give play to their advantages in logical thinking ability; (3) Prospects: early intervention was needed to enhance professional identity and organizational support; male nurses should be trained in various aspects through multiple forms such as counterpart assistance, expert databases or online academic forums; interdisciplinary development might be the key to stimulating internal driving force.Conclusions:Significant progress has been made in the career development of male nurses in China, but there are still challenges and issues to address. Further improvements in related policies, enhancement of social recognition and professional status, and increased investment and support in research and education are needed to promote the sustained development of male nursing careers.
