Objectives:To investigate the epidemiological characteristics and ethnic differences of cardiovascular-kidney-metabolic syndrome(CKM)among the Hani,Dai,Bai,and Lisu populations in Yunnan Province,and to provide evidence for developing effective prevention and control strategies for CKM.Methods:A cross-sectional survey was conducted among four ethnic minority groups.A total of 3 906 permanent residents aged 18 years and older were enrolled using a multistage cluster random sampling method.CKM stages(0-4)were defined based on the 2023 American Heart Association criteria,stages 3-4 were classified as advanced CKM.Descriptive statistics and chi-square tests were used to compare the prevalence of CKM stages across ethnic groups.Modified Poisson regression was applied to estimate relative risk(RR)and 95%confidence intervals(CI)for factors associated with advanced CKM.Results:The prevalence rates of CKM stage 1 and above among the Hani,Dai,Bai and Lisu ethnic groups were 80.1%,87.3%,84.8%and 67.8%,respectively.The prevalence of CKM was generally higher in males than in females,and the prevalence of CKM increased significantly with age.The Dai ethnic group had the highest prevalence of advanced CKM(24.7%,95%CI:22.1%-27.4%),while the Lisu ethnic group had the lowest prevalence of advanced CKM(13.7%,95%CI:11.5%-15.9%).Modified Poisson regression analysis showed that older age and higher body mass index were common risk factors for advanced CKM across all four ethnic groups.Additionally,except for the Lisu ethnic group,the other three ethnic groups had specific individual risk factors:among the Hani ethnic group,low educational attainment(RR=2.18,95%CI:1.12-4.25)and low income(RR=1.47,95%CI:1.00-2.18)were the primary risk factors of CKM.Among the Dai ethnic group,smoking(RR=1.60,95%CI:1.07-2.37)and a family history of cardiovascular disease(RR=1.61,95%CI:1.14-2.27)are the primary risk factors of CKM.Among the Bai ethnic group,male gender(RR=0.48,95%CI:0.29-0.79)was the primary risk factor of CKM.Conclusions:The prevalence of CKM stage 1 or higher is relatively high among the four minority ethnic groups in Yunnan province.There are significant differences in staging characteristics and primary risk factors across ethnic groups,necessitating the development of stratified,differentiated intervention strategies to achieve precise prevention and control and ethnic health equity in terms of CKM.

Objective:To develop a rapid assessment scale for healthy aging suitable for the Chinese population.Methods:Based on existing healthy aging assessment scales, national standards, and expert consensus, an initial Healthy Aging Rapid Assessment Scale was drafted through two rounds of expert consultation. A pre-survey was conducted with 3 220 subjects recruited from Guangzhou between July 2023 and July 2024. Items were screened through item analysis and exploratory factor analysis to form the final scale. Reliability and validity of the final scale were validated across five cities: Guangzhou, Dongguan, Shenzhen, Baoding, and Chuxiong.Results:The initial version comprised 36 items, while the finalized scale contained 18 items across three dimensions: metabolic health, mental health, and cognitive health. Test-retest reliability ranged from 0.71 to 0.81 across all study sites. The Spearman-Brown coefficient varied between 0.91-0.96, Cronbach′s α between 0.77-0.83, comparative fit index (CFI) between 0.90-0.98, goodness-of-fit index (GFI) between 0.90-0.99, and root-mean-square error of approximation (RMSEA) between 0.03-0.09. For the three dimensions, reliability and validity metrics demonstrated consistency: Spearman-Brown coefficients 0.87-0.99, Cronbach′s α 0.77-0.83, CFI 0.90-0.98, GFI 0.90-0.99, and RMSEA 0.03-0.09 across four regions.Conclusion:The developed Healthy Aging Rapid Assessment Scale for the Chinese population exhibits robust reliability and validity.

Objective To explore the mechanism of Lidan Huatan Huoxue Decoction improving cognitive impairment caused by obesity based on metabolomics.Methods Twenty-four 6-week-old male SD rats were randomly divided into a normal group fed with regular diet(Con,n=6)and a modeling group fed with high-fat and high-sugar diet(n=18).Rats with a body mass that is 20%higher than the standard body mass of their age-matched peers fed with ordinary diet were considered to have a successful obese model established.The presence of cognitive impairment was assessed by Morris water maze and Barnes maze tests.After the obese-induced cognitive impairment(OICI)model was established,the modeling rats were randomly divided into a model group(Model,n=6),a donepezil group(Donepezil,n=6),and a Lidan Huatan Huoxue Decoction group(LHH,n=6).Drugs were administered to the donepezil and LHH groups by gastric intubation.The donepezil group was administered with a dose of 0.45 mg·(kg·d)-1,while the LHH group was administered with a dose of 25 g·(kg·d)-1.The normal and model groups were given the same volume of normal saline by gastric intubation for 8 weeks.Before the rats were sacrificed,water maze and Barnes maze experiments were conducted to assess cognitive function.After sacrifice,specimens were collected for biochemical and histological examination of liver tissue and brain tissue.Non-targeted metabolomic analysis using liquid chromatography-mass spectrometry(LC-MS)was performed on feces,serum,and brain tissue to analyze changes in differential metabolites in rats.Results Compared with the model group,the intervention of Donepezil and LHH effectively improved the learning and memory ability of OICI rats(P<0.05 or P<0.01),inhibited the overactivation of hippocampal microglia,and increased the number of hippocampal synaptic proteins.LHH improved metabolic-related indicators in OICI rats(P<0.05 or P<0.01).Metabolomic analysis showed significant differences in metabolites in feces,serum,and brain tissue between the model group and the normal group.The main affected pathways in fecal metabolites included steroid biosynthesis,caffeine metabolism,lysosome,vitamin B6 metabolism,phenylalanine,tyrosine,and tryptophan biosynthesis.The main affected pathways in serum metabolites included central carbon metabolism in cancer,pentose phosphate pathway,mineral absorption,protein digestion and absorption,and aminoacyl-tRNA biosynthesis.The main affected pathways in brain tissue metabolites included glycerophospholipid metabolism,β-alanine metabolism,propionic acid metabolism,niacin and nicotinamide metabolism,and caffeine metabolism.After LHH intervention,fecal metabolites showed the most significant changes,mainly involving vitamin B6 metabolism,vitamin digestion and absorption,histidine metabolism,fructose and mannose metabolism,and steroid biosynthesis.Conclusion LHH can improve cognitive impairment in obese rats mainly by regulating fecal metabolites.The main pathways involved include vitamin B6 metabolism,vitamin digestion and absorption,histidine metabolism,fructose and mannose metabolism,and steroid biosynthesis.Among them,vitamin B6 metabolism and vitamin digestion and absorption may be the most important pathways.

Objective:To investigate the protective effect of fluoxetine on neurons in rats with subarachnoid hemorrhage (SAH) and explore its mechanism based on the chemokine receptor 4 (CXCR4)/nucleotide-binding oligomerization domain-like receptor protein 1 (NLRP1) pathway.Methods:Seventy-five rats were randomly divided into a normal control group and a model group. The SAH model was established by the internal carotid artery puncture method in the model group. After modeling, rats were randomly divided into the model group, fluoxetine low-, medium-, and high-dose groups, and nimodipine group, with 12 rats in each group. The fluoxetine low-, medium-, and high-dose groups were intravenously injected with fluoxetine at doses of 5, 10, and 15 mg/kg, respectively; the nimodipine group was intraperitoneally injected with nimodipine at 0.2 mg/kg; the normal control group and model group were intraperitoneally injected with an equal volume of normal saline, once a day for 7 consecutive days. The shuttle box was used to determine the number of avoidance responses and avoidance response time of rats. The water content of brain tissue and Evans blue exudation volume were calculated. Enzyme-linked immunosorbent assay (ELISA) kits were used to detect the levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) in the hippocampal tissue. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of hippocampal tissue. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the mRNA levels of CXCR4 and NLRP1 in the hippocampal tissue. Western blot was used to determine the protein levels of CXCR4, NLRP1, LC3-Ⅱ, and Beclin1 in the hippocampal tissue.Results:Compared with the normal control group, the model group had a lower number of avoidance responses, lower levels of SOD, CAT, GSH, CXCR4 mRNA, CXCR4, LC3-Ⅱ, and Beclin1 protein in the hippocampal tissue (all P<0.05); while the avoidance response time, brain water content, Evans blue exudation volume, levels of IL-6, TNF-α, MDA, and mRNA and protein levels of NLRP1 in the hippocampal tissue were higher (all P<0.05). Compared with the model group, the fluoxetine groups (all doses) and nimodipine group had a higher number of avoidance responses, higher levels of SOD, CAT, GSH, CXCR4 mRNA, CXCR4, LC3-Ⅱ, and Beclin1 protein in the hippocampal tissue (all P<0.05); while the avoidance response time, brain water content, Evans blue exudation volume, levels of IL-6, TNF-α, MDA, and mRNA and protein levels of NLRP1 in the hippocampal tissue were lower (all P<0.05); moreover, the changes in various indicators were more significant with the increase of fluoxetine dose. HE staining results showed that there were no pathological changes in the hippocampal tissue of the normal control group; in the model group, the number of hippocampal neurons decreased, nuclei were pycnotic, and cell arrangement was irregular. Compared with the model group, the number of hippocampal neurons increased, cell arrangement was regular, and hippocampal pathology was significantly restored in the fluoxetine groups (all doses) and nimodipine group. Conclusions:Fluoxetine can significantly alleviate the pathological progression of cerebral edema, repair neuronal damage, improve neurological function, and regulate mitochondrial autophagy in SAH rats, whose mechanism may be related to the regulation of the CXCR4/NLRP1 pathway.

Objective:To identify the multidimensional health management needs of young and middle-aged women with breast cancer based on a patient journey map, with the aim of improving prognosis and quality of life in this population.Methods:A descriptive qualitative research approach was employed. From November 2024 to February 2025, in-depth interviews were conducted with 20 young and middle-aged female patients undergoing treatment for breast cancer at the First Affiliated Hospital of Nanjing Medical University. Data were analyzed using conventional content analysis, and a patient journey map was developed.Results:Along the treatment timeline, patients' health management needs were categorized and refined from three dimensions—tasks, pain points, and emotions—into key themes: limited disease awareness, need for early detection and treatment, decision on the treatment plane, lack of nutritional support, impairment of intimate relationships and impact on fertility, body image and self-identity, and coping with changes in social relationships. These findings were integrated into a visualized patient journey map.Conclusions:The health management journey of young and middle-aged women with breast cancer is long and deeply personal, characterized by complex and diverse needs. The patient journey map systematically illustrates patients' dynamic experiences, perceptions, and behaviors as they interact with multiple events, changing environments, and varied healthcare services. It also reveals the internal drivers behind decision-making processes, uncovering unmet needs that may not be readily apparent. This process enables healthcare professionals to adopt a patient-centered approach to innovatively optimize interventions, thereby improving the precision and appropriateness of healthcare services.

Objective:To compare the effects of different appointment regimens on the daily waiting time, fixedness of treatment time and lateness rate of radiotherapy patients.Methods:Medical records of 5488 radiotherapy from 332 patients on the same linear accelerator in West China Hospital of Sichuan University from March to June 2022 were selected. Based on the radiotherapy information integration platform of MOSAIQ, all patients were randomly assigned to the morning class, afternoon class and evening class. Traditional manual appointment regimen was adopted for the morning class, 30 min appointment regimen for the afternoon class, and 15 min appointment regimen for the evening class, respectively. The differences in patient waiting time for treatment, fixedness of treatment time, and lateness rate under different appointment regimens were compared. The fixedness of treatment time and waiting time was determined by one-way ANOVA, and the 2×3 Chi-square test was adopted for the lateness rate. Results:The waiting time in the 15 min appointment, the 30 min appointment and manual appointment groups were (27.08 ± 17.21), (34.57± 19.12) and (41.50 ±20.94) min, respectively. There was statistical significance among three appointment regimens ( F=254.97, P<0.001). The waiting time was the shortest in the 15 min appointment group, followed by the 30 min appointment group, and the manual appointment group (all P<0.001 for two-group comparison). The fixedness of treatment time in the 15 min appointment, the 30 min appointment and the manual appointment groups were (15.60±7.87), (18.69±8.94) and (24.30±15.10) min, respectively. There was statistical significance among three groups ( F=25.23, P<0.001). Among them, the fixedness of treatment time in the 15 min appointment group was the highest, followed by the 30 min appointment group, and the manual appointment group (all P<0.001). The lateness rates in the 15 min appointment, the 30 min appointment and the manual appointment groups were 5.7%, 6.2% and 9.6%, respectively. The lateness rate in the manual appointment group was higher than those in the 15 min appointment and the 30 min appointment groups ( χ2=19.24、14.90, both P<0.001), but there was no statistical significance in the lateness rate between the 15 min appointment and 30min appointment groups ( χ2=0.39, P=0.535). Conclusion:In the clinical practice of conventional intensity-modulated radiotherapy technology carried out by conventional linear accelerator, the 15 min appointment regimen can shorten the waiting time for radiotherapy and improve the fixedness of daily radiotherapy time, which is worthy of clinical promotion.
