ObjectiveTo explore the effects of Jingui Shenqiwan (JSW) and Liuwei Dihuangwan (LDW) on the reproductive ability and brain function of normal mice and compare the actions of the two medications. MethodsSeven groups of female and male mice were divided at a ratio of 2∶1. Except for the control group, the other six groups were as follows: a group of both males and females receiving JSW (3.0 g·kg-1), a group of both males and females receiving LDW (4.5 g·kg-1), a group of males receiving water and females receiving JSW, a group of males receiving water while females receiving LDW, a group of females receiving water while males receiving JSW, and a group of females receiving water while males receiving LDW. Each group was administered the drug for 14 days and then caged together at a 2∶1 (female∶male) ratio to detect the number of pregnant mice and calculate the pregnancy rate. Pregnant mice continued receiving the drug until they naturally gave birth, which was followed by the observation of newborn mice, calculation of their average number, and the measurement of the offspring's preference for sugar water and neonatal recognition index. At the end of the experiment, the weights of the thymus and spleen were measured to calculate the organ coefficients, and mRNA or protein expression was analyzed in the brain and testes or ovaries. A 1% sucrose solution was used to examine the euphoria of their brain reward systems, while novel object recognition test (NOR) was applied to assess their memory capabilities. mRNA expression was detected using real-time quantitative polymerase chain reaction (Real-time PCR) assay, and protein expression was analyzed with Western blot. ResultsCompared with the control group, oral administration of JSW to both male and female mice for 14 days significantly increased the pregnancy rate of female mice on day 2 after being caged together (P<0.05), while LDW showed a trend but no statistical significance. Additionally, compared with the control group, JSW could upregulate the gene expression of gonadotropin-releasing hormone (GnRH) in the thalamus, as well as reproductive stem cell factor (SCF) and tyrosine kinase receptor (c-Kit) in the testes and reproductive stem cell marker mouse vasa homologue (MVH) in the ovaries, upregulate the expression of proteins influencing neuronal functional activity, such as brain-derived neurotrophic factor (BDNF), in hippocampal neurons (P<0.05), and enhance sucrose preference in male mice (P<0.05). Compared with the control group, JSW significantly increased sucrose preference and novel object recognition index in offspring mice (P<0.05), which was related to the upregulation of hippocampal dopamine D1 receptor (D1R) and N-methyl-D-aspartate receptor (Nmdar) gene expression. Compared with the control group, both JSW and LDW could upregulate the protein expression of glucocorticoid receptor (GR), BDNF, and tyrosine kinase receptor B (TrkB) in the hippocampus of offspring mice (P<0.05). ConclusionJSW significantly enhances the reproductive ability of normal mice, which is not only related to the release of gonadotropin but also associated with its regulation of brain function. Additionally, JSW has a certain regulatory effect on the brain function of the offspring mice.

Objective:
To systematically characterize the developmental trajectory and interdisciplinary integration of intelligent diagnosis in traditional Chinese medicine (TCM) through quantitative topic evolution analysis, we addressed the fragmentation of existing research and clarified the long-term research structure and evolutionary patterns of the field.
Methods:
A topic evolution analysis was performed on Chinese-language literature pertaining to intelligent diagnosis in TCM. Publications were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang Data, and China Science and Technology Journal Database (VIP), covering the period from database inception to July 3, 2025. A hybrid segmentation approach, based on cumulative publication growth trends and inflection point detection, was applied to divide the research timeline into distinct stages. Subsequently, the latent Dirichlet allocation (LDA) model was used to extract research topics, followed by alignment and evolutionary analysis of topics across different stages.
Results:
A total of 3 919 publications published between 2003 and 2025 were included, and the research trajectory was divided into five stages based on data-driven breakpoint detection. The field exhibited a clear evolutionary shift from early rule-based systems and tongue-pulse image and signal analysis (2006 – 2010), to machine-learning-based syndrome and prescription modeling (2011 – 2015), followed by deep-learning-driven pattern recognition and formula association (2016 – 2020). Since 2021, research has increasingly emphasized knowledge-graph construction, multimodal integration, and intelligent clinical decision-support systems, with recent studies (2024 – 2025) showing the emergence of large language models and agent-based diagnostic frameworks. Topic evolution analysis further revealed sustained cross-stage continuity in syndrome modeling and prescription association analysis, alongside the progressive consolidation of integrated intelligent diagnostic platforms.
Conclusion
By identifying key technological transitions and persistent core research themes, our findings offer a structured reference framework for the design of intelligent diagnostic systems, the construction of knowledge-driven clinical decision-support tools, and the alignment of AI models with TCM diagnostic logic. Importantly, the stage-based evolutionary insights derived from this analysis can inform future methodological choices, improve model interpretability and clinical applicability, and support the translation of intelligent TCM diagnosis from experimental research to real-world clinical practice.

To investigate the risk factors for acute kidney injury (AKI) following the use of amphotericin B deoxycholate and to develop a predictive model to guide clinical monitoring and intervention. A retrospective analysis was conducted on hospitalized patients who received amphotericin B deoxycholate between January 2014 and September 2024. Patients were divided into a training set and a validation set. Demographic data, laboratory findings, and medication orders were collected. Based on the occurrence of AKI during treatment and within 7 days after discontinuation, patients were classified into an AKI group and a non-AKI group. Univariate analysis was used to screen for potential risk factors, multivariate logistic regression was employed to construct a predictive model, and model performance was evaluated using the area under the receiver operating characteristic curve (AUC) and the Hosmer-Lemeshow test. The training set included 473 patients, comprising 255 males (53.91%) and 218 females (46.09%), with a median age of 52(35, 62) years. The AKI group consisted of 191 cases (40.38%), and the non-AKI group consisted of 282 cases (59.62%). The validation set included 114 patients, comprising 80 males (70.18%) and 34 females (29.82%), with a median age of 43.5 (31.0, 58.5) years. The AKI group consisted of 42 cases (36.84%), and the non-AKI group consisted of 72 cases (63.16%). Univariate analysis revealed statistically significant differences between the two groups in 23 factors (all Admission to the ICU, elevated serum creatinine at admission, and comorbid cardiac insufficiency as potential risk factors for AKI, while prophylactic use of diphenhydramine/promethazine or sodium bicarbonate showed a protective association. A predictive model with good discrimina-tion and calibration was developed, which may provide a basis for early identification of high-risk patients and timely adjustment of treatment strategies in clinical practice.

Objective:To explore the effectiveness of interprofessional cooperative simulation in teaching emergency care for shock patients among intensive care unit (ICU) undergraduate nursing students.Methods:An interprofessional cooperative simulation-based teaching faculty team was established for ICU undergraduate nursing students, and a shock case library was developed. Using convenience sampling, 32 ICU undergraduate nursing students in 2022 were selected as the control group and received conventional simulation-based teaching, with students rotating through roles as nurses, standardized patients, doctors, and family members. In the experimental group, 34 ICU undergraduate nursing students in 2023 and 24 ICU clinical medicine interns were recruited to act as doctors for interprofessional cooperative simulation-based teaching. Each group was divided into subgroups, with each subgroup consisting of 4-5 nursing students. One group completed simulation-based training per month for a total of 8 sessions, with each session lasting 3 hours. The teaching adopted the on-site "tidal ward" in situ simulation, and the scenarios included patient history collection and health assessment, shock emergency care, nursing evaluation, and health education. The differences between the two groups of nursing students were compared in terms of ICU exit theoretical assessment score, objective structured clinical examination skill assessment score, and satisfaction with simulation-based teaching. SPSS 22.0 was used for independent samples t test and Mann-Whitney U test. Results:The experimental group achieved significantly higher scores in theoretical assessment (84.65±8.06), total score of satisfaction with simulation-based teaching (101.00±5.13), and clinical learning and multiprofessional team dimensions (47.32±3.35) compared to the control group ( P<0.001). The experimental group achieved higher scores in objective structured clinical examination skill assessment (81.40±7.22), guiding feedback and reflection (37.50±3.04), and judgmental thinking and clinical reasoning (16.00±2.03) compared to the control group, though the differences were not significant ( P=0.977, 0.668, and 0.636). Conclusions:Interprofessional cooperative simulation enhances the shock patient emergency care abilities and satisfaction with simulation-based teaching for undergraduate nursing students.
