Objective:To explore the distribution of cardiovascular disease(CVD)and cardiovascular risk fac-tors(CVRF)in patients with epithelial ovarian cancer before treatment and their correlation with the histological type,stage and grade of ovarian cancer.Methods:A total of 401 newly diagnosed epithelial ovarian cancer pa-tients admitted to The First Affiliated Hospital of Dalian Medical University from January 1,2015 to December 31,2022 were enrolled.Analyze the distribution of CVD(including hypertension,coronary heart disease,stroke,etc.)and CVRF(including diabetes,dyslipidemia,high level of uric acid)in epithelial ovarian cancer patients.Univari-ate analysis and multivariate Logistic regression were performed on the association between CVD,CVRF and the histological type,grade and stage of epithelial ovarian cancer.Results:①Among 401 epithelial ovarian cancer pa-tients,43.6％had at least one CVD before therapy.The most common CVD was hypertension(41.1％),and the most common CVRF was dyslipidemia(57.9％).②Multivariate Logistic regression analysis showed that age ≥60 years was an independent risk factor for serous,high-grade,and advanced epithelial ovarian cancer(OR＞1,P＜0.05).Dyslipidemia was an independent risk factor for high-grade and advanced epithelial ovarian cancer(OR＞1,P＜0.05).High level of uric acid was an independent risk factor for advanced epithelial ovarian cancer(OR＞1,P＜0.05).③The proportion of high-density lipoprotein cholesterol(HDL-C)and lipoprotein A[Lp(A)]abnor-malities in patients with advanced epithelial ovarian cancer was significantly higher than in those with early stage epithelial ovarian cancer(P＜0.05),and the proportion of number of abnormal lipid components was higher in pa-tients with high grade and advanced epithelial ovarian cancer than in patients with low grade and early stage epi-thelial ovarian cancer,respectively(P＜0.05).Conclusions:Patients with epithelial ovarian cancer bear a signifi-cant burden of CVD and CVRF.Hypertension is the most common CVD,and dyslipidemia is the most common CVRF.Dyslipidemia was associated with epithelial ovarian cancer grade and stage.High level of uric acid was as-sociated with epithelial ovarian cancer stage.Active control of blood pressure and blood lipid levels is very impor-tant for epithelial ovarian cancer patients.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective: To investigate the effects of Zuogui Jiangtang Jieyu Formula (ZGJTJYF) on histone H3 lysine 18 lactylation (H3K18la) in the hippocampus of rats with diabetes mellitus complicated with depression (DD) and predict the regulatory genes of H3K18la. Methods: Male Sprague-Dawley rats were divided into control, model, and positive drug (metformin [0.18 g/kg] and fluoxetine [1.8 mg/kg]) groups, and the three groups were treated with high, medium, and low ZGJTJYF doses (20.52, 10.26, and 5.13 g/kg, respectively), with 10 rats per group. After treatment, the forced swimming and water maze tests were performed to assess depressive-like behaviors and cognitive function. An enzyme-linked immunosorbent assay was used to measure blood insulin, glycosylated hemoglobin, lactate levels, and lactate content in the hippocampus. Western blotting was used to detect H3K18la expression in the hippocampus. Cleavage Under Targets and lagmentation(CUT&Tag) experiments targeted hippocampal H3K18la epigenetic modification regions to analyze the transcription factors bound by H3K18la. Kyoto Encyclopedia of Genes and Genomes and Protein-Protein Interaction networks were constructed to identify key pathways and target genes regulated by H3K18la. Results: Compared with the normal group, the model group rats showed prolonged immobility time in the forced swim test, increased escape latency in the water maze experiment, decreased target quadrant distance ratio (P<0.01), increased serum lactate content, and decreased lactate content in hippocampal homogenate (P<0.01), as well as decreased H3K18la protein expression in the hippocampus (P<0.01). Compared with the model group, ZGJTJYF reduced the immobility time in the forced swim test and the escape latency in the water maze test (P<0.01), while the distance ratio in the target quadrant increased (P<0.01) in model rats. Lowered fasting blood glucose, insulin, and glycosylated hemoglobin levels (P<0.05, P<0.01) were also observed. ZGJTJYF also increased the lactate content and H3K18la protein expression in hippocampal homogenate (P<0.05, P<0.01). The DNA sequences bound by H3K18la were predominantly enriched at the transcription start sites. ZGJTJYF modulated H3K18la-associated pathways, including cell adhesion junctions, tumor growth factor-beta (TGF-β) signaling, stem cell pluripotency regulation, mitogen-activated protein kinase(MAPK) signaling pathway, and insulin resistance, leading to the identification of 12 target genes. Conclusion ZGJTJYF enhances hippocampal lactate levels and H3K18la modification in DD rats, which may regulate neural cell interactions, neurogenic stem cell function, TGF-β signaling, MAPK signaling, and insulin resistance pathways.

Objective:To investigate the detection status of pulmonary tuberculosis (PTB) among patients aged ≥65 years in China and provide evidence for improving PTB prevention and control in this population.Methods:The data were collected from the tuberculosis subsystem of Chinese Disease Control and Prevention Information System, and the case information of elderly PTB patients aged ≥65 years old who were registered in designated tuberculosis medical institutions nationwide from January 1, 2015 to December 31, 2023.Descriptive epidemiological methods were used to analyze trends in detection status, regional differences, and demographic characteristics.Results:From 2015 to 2023, 1 567 047 elderly PTB detection were identified, accounting for 25.1% of all PTB patients (1 567 047/6 243 215). The average registration rate for elderly PTB patients was 96.9 per 100 000, approximately twice that of the general population. The registration rate declined over the years ( Z=-2.61, P=0.009) but increased in 2018 and 2023. The proportion of elderly PTB patients rose annually, from 21.3% in 2015 to 32.4% in 2023 ( Z=2.30, P=0.022). Active case-finding accounted for only 3.0% (47 049/1 567 047) of patients on average during the study period, peaking at 7.3% (14 123/194 615) in 2018 before declining. The registration rates of elderly tuberculosis patients are relatively higher in central and western regions. In the central region, the average registration rate was 113.8 per 100 000, with a proportion of active case detection of 0.4% (2 532/570 059). In the western region, the average registration rate was 130.0 per 100 000, and the proportion of active case-finding was 7.6% (41 973/549 998). Subgroups with notably lower active detection proportions included males (2.5%, 27 443/1 101 091), those aged 80-84 years (2.2%, 2 978/133 855), and migrant populations (0.5%, 1 635/307 673). Conclusions:The burden of PTB among the elderly aged ≥65 years in China remains high, with a low proportion of active case-finding from 2015-2023. There is an urgent need to strengthen health education and active screening to improve the early diagnosis and prevention of tuberculosis in the elderly.
