BACKGROUND: The American Heart Association (AHA) introduced the concept of cardiovascular-kidney-metabolic (CKM) health and stage, reflecting the interaction among metabolism, chronic kidney disease (CKD), and the cardiovascular system. However, the association between CKM stage and the long-term risk of cardiovascular disease (CVD) has not been validated. This study aimed to evaluate the long-term CVD risk associated with CKM health metrics and CKM stage using data from a population-based cohort study. METHODS: In total, 5293 CVD-free participants were followed up to around 13 years in the Chinese Multi-provincial Cohort Study (CMCS). Considering the pathophysiologic progression of CKM health metrics abnormalities (comprising obesity, central adiposity, prediabetes, diabetes, hypertriglyceridemia, CKD, and metabolic syndrome), participants were divided into CKM stages 0, 1, and 2. The time-dependent Cox regression models were used to estimate the cardiovascular risk associated with CKM health metrics and stage. Additionally, broader CVD outcomes were examined, with a specific assessment of the impact of stage 3 in 2581 participants from the CMCS-Beijing subcohort. RESULTS: Among participants, 91.2% (4825/5293) had at least one abnormal CKM health metric, 8.8% (468/5293), 13.3% (704/5293), and 77.9% (4121/5293) were in CKM stages 0, 1, and 2, respectively; and 710 incident CVD cases occurred during a median follow-up time of 13.3 years (interquartile range: 12.1 to 13.6 years). Participants with each poor CKM health metric exhibited significantly higher CVD risk. Compared with stage 0, the hazard ratio (HR) (95% confidence interval [CI]) for CVD incidence was 1.31 (0.84-2.04) in stage 1 and 2.27 (1.57-3.28) in stage 2. Significant interactive impacts existed between CKM stage and age or sex, with higher CVD risk related to increased CKM stages in participants aged <60 years or females. CONCLUSION These findings highlight the contribution of CKM health metrics and CKM stage to the long-term risk of CVD, suggesting the importance of multi-component recognition and management of poor CKM health in CVD prevention.

Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

BACKGROUND: There is growing evidence that the occurrence and severity of respiratory diseases in children are related to the concentration of air pollutants. Nonetheless, evidence regarding the association between short-term exposure to air pollution and outpatient visits for respiratory diseases in children remains limited. Outpatients cover a wide range of disease severity, including both severe and mild cases, some of which may need to be transferred to inpatient treatment. This study aimed to quantitatively evaluate the impact of short-term ambient air pollution exposure on outpatient visits for respiratory conditions in children. METHODS: This study employed data of the Second People's Hospital of Yichang from January 1, 2016 to December 31, 2023, to conduct a time series analysis. The DLNM approach was integrated with a generalized additive model to examine the daily outpatient visits of pediatric patients with respiratory illnesses in hospital, alongside air pollution data obtained from monitoring stations. Adjustments were made for long-term trends, meteorological variables, and other influencing factors. RESULTS: A nonlinear association was identified between PM_2.5, PM₁₀, O₃, NO₂, SO₂, CO levels and the daily outpatient visits for respiratory diseases among children. All six pollutants exhibit a hysteresis impact, with varying durations ranging from 4 to 6 days. The risks associated with air pollutants differ across various categories of children's respiratory diseases; notably, O₃ and CO do not show statistical significance concerning the risk of chronic respiratory conditions. Furthermore, the results of infectious respiratory diseases were similar with those of respiratory diseases. CONCLUSIONS Our results indicated that short-term exposure to air pollutants may contribute to an increased incidence of outpatient visits for respiratory illnesses among children, and controlling air pollution is important to protect children's health.

Refractory inner ear disease refers to a spectrum of inner ear diseases that fail to achieve good therapeutic effects even after standardized treatment recommended by existing clinical practice guidelines. This disease spectrum is characterized by diverse etiological factors, high phenotypic heterogeneity, unclear subtype characteristics, unknown pathogenic mechanisms, and variable prognosis, making it difficult to define precisely. Refractory inner ear disease accounts for a significant proportion of the total population with inner ear diseases and has not been systematically summarized, refined, and deeply studied to date. This article, for the first time, clearly proposes the concept, definition, and scope of refractory inner ear disease, and elaborates on the current research status, challenges, and coping strategies for refractory inner ear disease. With the development and progress of science and technology, we believe that in the future we will witness more innovative technologies and new drugs applied to the treatment of refractory inner ear disease, bringing hope of cure to patients.

Objective:To investigate the clinical characteristics and treatment outcomes of patients with blast-induced hearing loss（BIHL）. Methods:The clinical features, laboratory parameters, audiometric profiles, and treatment efficacy of patients with blast induced hearing loss and those with idiopathic sudden hearing loss（ISHL） were analyzed using t-tests, Wilcoxon rank-sum tests, and chi-square tests, with a significance level set at P<0.05. Results:A total of 59 patients in the BIHL group and 117 patients in the ISHL group were included in this study. The mean age of the BIHL group was（39.07±14.49） years, comprising 45 males and 14 females. After the blast, 21 patients went to the hospital within the initial 14-day period, and an additional 38 patients seeking admission thereafter. In the BIHL group, 33 patients had unilateral hearing loss with PTA of （50.30±28.85） dB HL, while 26 had bilateral hearing loss with a PTA of（44.54±26.22） dB HL. In comparison, among the ISHL group, 112 patients had unilateral hearing loss with a PTA of（56.28±14.19） dB HL, and 5 had bilateral involvement with a PTA of（56.25±35.14） dB HL. The effective treatment rate within 14 days for the BIHL group was 31.8%, while for the ISHL group, the effective rate within 14 days was 77.0%. Conclusion:Blast-induced hearing loss is caused by exposure to high-intensity noise. The overall treatment effectiveness during hospitalization is lower compared to idiopathic sudden hearing loss, and the treatment window is shorter. Therefore, greater emphasis should be placed on prevention.

It can be summarized as “political firmness， excellent technology， working hard， and healing the wounded and rescuing the dying.” This content has many hidden similarities and integrations with the goal of cultivating humanistic literacy for medical students in military medical universities. This paper aimed to identify the important connection points between the red doctor spirit and the contents and goals of medical humanities teaching， as well as integrate the red doctor spirit into medical humanities teaching by various dimensions， including systematic reconstruction of textbook content， immersive innovation in teaching form， three-dimensional support in resource construction， and innovative implementation of narrative medicine teaching. It also further explored the extension of the red doctor spirit in military medical humanistic literacy， namely， revolutionary humanism and revolutionary heroism， thereby enhancing the effectiveness of medical humanistic teaching.

Palliative care is a way to help end-of-life populations improve their quality of life， and its development in practice cannot be separated from the level of education in palliative care. At present， some medical schools in palliative care education compared with western developed countries have problems such as imperfect construction of hospice curriculum system， lack of medical students’ hospice knowledge； insufficient interdisciplinary teaching faculty， weak palliative care awareness of medical students； single teaching evaluation mode； weak palliative care practice teaching links. To this end， it is necessary to improve the palliative care curriculum system， explore rich and diverse teaching methods； strengthen interdisciplinary teaching and faculty development， enhancing the awareness of palliative care among medical students；establish a scientific and effective evaluation method， carry out multi-dimensional dynamic assessment； expand the palliative care practice teaching base， and accurately improve the practical skills of medical students in palliative care， and other countermeasures to improve the level of palliative care education， and to help the strategy of Healthy China.
