Objective: To summarize strategies for improving childhood hypertension, so as to provide evidencebased recommendations for poliymaking and practice childhood hypertension management in China. Methods: From March to April 2024, child health stakeholders from five districts in Hangzhou were selected using a combination of stratified and convenience sampling methods. Data were analyzed using a groundedtheory approach. During the indepth interview phase, six policymakers were interviewed. Focus group discussions were conducted with school administrators, healthcare providers, and parents, comprising a total of 62 participants. Results: Through threelevel coding, 116 initial categories were identified(e.g., "trend of younger age" "difficulty in behavior change"), 35 main categories (e.g., "higher incidence compared to the past" "caused by comprehensive influencing factors"), and 12 core categories (e.g., "epidemic status" "influencing factors"). Finally, the cognitive status, problem analysis, and management strategies of children hypertension were constructed. Conclusion Effective prevention and control of childhood hypertension requires coordinated efforts among governments, schools, families, and society to establish a comprehensive management system, with dynamic monitoring and evaluation to optimize policy implementation.

The study analyzes the global prevalence of childhood hypertension and the relationship between macroecological factors, meso environmental factors, and micro individual factors based on the perspective of life course and childhood hypertension. And it further summarizes existing prevention and control strategies: systematic prevention and control based on policy and social support, health promotion based on behavioral science theory, and dynamic monitoring and management based on individualized prevention and control, to provide a reference for promoting the advancement of childhood hypertension prevention and control strategies.

OBJECTIVES: To investigate the molecular mechanism by which Lichong Xiaozheng Granules (LCXZ) sensitize ovarian cancer to cisplatin (DDP) treatment. METHODS: LC-MS analysis was used to identify the blood components of LCXZ after its administration in mice via gavage. In a BALB/c mouse model bearing subcutaneous ovarian cancer xenografts, the effects of daily gavage of distilled water (control group), intraperitoneal injection of DDP (5 mg/kg) once a week, or both DDP injection and daily LCXZK gavage (15 g/kg) on tumor growth were evaluated. Histopathological changes in the xenografts and kidneys were assessed with HE staining. RNA-seq was performed to identify the differentially expressed genes followed by KEGG pathway analysis. The changes in mitochondrial ultrastructure and expressions of mitochondrial apoptosis-related were examined with transmission electron microscopy and Western blotting. RESULTS: A total of 218 blood-borne components of LCXZ were detected by LC-MS. In the tumor-bearing mice, treatments with DDP and DDP combined with LCXZ redcued the tumor volume by 60.3% and 72.6% compared with that in the control group, respectively. Transcriptomic analysis revealed significantly upregulated ANT3 expression in both the two treatment groups. Molecular docking indicated that the main active components of LCXZ were capable of binding to adenine nucleotide translocator 3 (ANT3) with binding energies below -6 kcal/mol. Transmission electron microscopy showed obvious mitochondrial swelling and outer-membrane damage in the tumor cells in DDP-treated mice, and these changes were more pronounced in the combined treatment group. The expression levels of BAX, ANT3, cleaved caspase-3 and cleaved caspase-9 were increased, whereas BCL-2 expression was decreased significantly in the tumor cells in both the DDP and DDP+LCXZ groups. CONCLUSIONS LCXZ enhances the therapeutic efficacy of cisplatin against ovarian cancer xenografts in mice by promoting mitochondrial dysfunction and activating apoptotic signaling pathways via upregulating ANT3.

Objective:To explore the correlation between MYB/NFIB gene fusion and clinicopathological features such as tumor grade and prognosis of head and neck adenoid cystic carcinoma (ACC), and to assess the concordant rate of fluorescent in situ hybridization (FISH) with MYB and NFIB immunohistochemistry.Methods:FISH detection of MYB/NFIB gene fusion was performed on 48 head and neck ACC cases and 15 non-ACC salivary gland tumors at National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China during April 2014 and January 2020. ACC cases were divided into grade Ⅰ-Ⅱ, grade Ⅲ and high-grade transformation, according to pathological grading criteria. Prognosis, FISH results and other clinicopathological characteristics were analyzed. MYB and NFIB immunohistochemistry was performed on the 48 ACC and 15 non-ACC cases. The diagnostic accuracy of FISH and immunohistochemistry was compared.Results:FISH detected MYB/NFIB gene fusion in 41.7% (20/48) of the ACC. Its positive rate was inversely correlated with higher pathological grades ( P=0.036). The higher histological grade was linked to worse progression-free survival ( P=0.024), whereas there was no correlation between the status of gene fusion detected by FISH and progression-free survival ( P=0.536). FISH didnot detect MYB/NFIB gene fusion in 15 non-ACC salivary gland tumors The specificity of diagnosing ACC is 100% for both FISH detection of gene fusion and immunohistochemical detection of MYB expression. However, the sensitivity for both methods was only about 41.7%, respectively. By combining FISH and MYB immunohistochemistry, the sensitivity for diagnosing ACC was increased to 66.7%. Conclusions:MYB/NFIB gene fusion has a lower detection rate in grade Ⅲ ACC and high-grade transformation ACC. Meanwhile gene fusion status is not correlated with prognosis. The sensitivity for diagnosing ACC can be improved by combining FISH and MYB immunohistochemistry.

Objective To investigate the relationship between sleep fragmentation(SF)parameters and left ventricular structure in a community-based elderly population using data collected from the Multi-Ethnic Study of Atherosclerosis(MESA)cohort.Methods A total of 1 404 participants from the MESA cohort who underwent polysomnography(PSG)and cardiac magnetic resonance(CMR)were included.PSG was used to assess SF parameters,including wake after sleep onset(WASO),arousal index-total(ArI-total),arousal index-rapid eye movement(ArI-REM),and arousal index-non-rapid eye movement(ArI-NREM).Left ventricular end-diastolic mass(LVEDM)was measured via CMR.Linear regression was employed to analyze the relationship between SF parameters and left ventricular mass to height ratio(LVHi).Results Univariate linear regression analysis showed that WASO[β 0.134;95％confi-dence interval(CI)0.023-0.052;P＜0.001],ArI-total(β 0.184;95％CI 0.203-0.362;P＜0.001),ArI-REM(β 0.116;95％CI 0.100-0.260;P＜0.001)and ArI-NREM(β 0.175;9 5％CI 0.176-0.323;P＜0.001)were positively correlated with LVHi.After adjust-ment for confounding factors in multivariate linear regression analysis,WASO(β 0.045;95％CI 0.001-0.024;P=0.033)was positively correlated with LVHi.WASO(β 0.089;95％CI 0.006-0.034;P=0.006)was significantly associated with increased LVHi in the female group but not in the male group.Conclusion In an ethnically diverse cohort,WASO is significantly associated with increased LVHi after adjustment for potential confounders,especially in the female elderly population.

Objective:To assess the efficacy of different fusion strategies involving the convolutional block attention module (CBAM) and Unet for automatic pancreas segmentation in enhanced CT images of patients with acute pancreatitis.Methods:A retrospective analysis was conducted on 1 158 patients with acute pancreatitis admitted to the Affiliated Hospital of North Sichuan Medical College between January 1st, 2016 and July 30th, 2021. Among them, 141 patients with first-episode acute pancreatitis were randomly categorized into mild, moderate, and severe cases. The test set comprised 5 mild and 15 severe cases, while the remaining 126 cases were used for training. Within the training set, 20% of the data was randomly allocated as the validation set. Different fusion paths of the CBAM and Unet networks were trained, utilizing the Dice similarity coefficient, Hausdorff distance (HD), and pixel accuracy (PA) as evaluation metrics. The model demonstrating the best performance on the validation set was selected and evaluated on the test set. Additionally, the Unet model was combined with the attention gate attention mechanism (AttentionUnet) in the skip connection, and the ResBlock replaced the original convolution module (ResUnet) in the Unet network. Moreover, the skip connection branch module of feature extraction was integrated with CBAM (ResUnet_CBAM) for comparison.Results:Unet_CBAM achieved better results on the test set with a Dice value of 80.06%, a HD value of 3.765 9 and a PA value of 0.992 3, all surpassing other fusion strategies. The segmentation accuracy of the pancreatic region in CT images of acute pancreatitis patients was notably enhanced compared to Unet and its related variant networks.Conclusions:The Unet network integrated into CBAM after skip connection can better perform pancreatic segmentation on enhanced CT images of patients with acute pancreatitis and can effectively improve the efficiency of relevant personnel in pancreatic segmentation on enhanced CT images of patients with acute pancreatitis.

Pathological vascular remodeling is a hallmark of various vascular diseases. Previous research has established the significance of andrographolide in maintaining gastric vascular homeostasis and its pivotal role in modulating endothelial barrier dysfunction, which leads to pathological vascular remodeling. Potassium dehydroandrographolide succinate (PDA), a derivative of andrographolide, has been clinically utilized in the treatment of inflammatory diseases precipitated by viral infections. This study investigates the potential of PDA in regulating pathological vascular remodeling. The effect of PDA on vascular remodeling was assessed through the complete ligation of the carotid artery in C57BL/6 mice. Experimental approaches, including rat aortic primary smooth muscle cell culture, flow cytometry, bromodeoxyuridine (BrdU) incorporation assay, Boyden chamber cell migration assay, spheroid sprouting assay, and Matrigel-based tube formation assay, were employed to evaluate the influence of PDA on the proliferation and motility of smooth muscle cells (SMCs). Molecular docking simulations and co-immunoprecipitation assays were conducted to examine protein interactions. The results revealed that PDA exacerbates vascular injury-induced pathological remodeling, as evidenced by enhanced neointima formation. PDA treatment significantly increased the proliferation and migration of SMCs. Further mechanistic studies disclosed that PDA upregulated myeloid differentiation factor 88 (MyD88) expression in SMCs and interacted with T-cadherin (CDH13). This interaction augmented proliferation, migration, and extracellular matrix deposition, culminating in pathological vascular remodeling. Our findings underscore the critical role of PDA in the regulation of pathological vascular remodeling, mediated through the MyD88/CDH13 signaling pathway.

Aim To reveal the mechanism of cross-species ischemic heart failure from the perspective of spatial and gene co-expression networks.Methods GSE210374 and GSE57338 high-throughput sequencing datas were re-trieved from the national center for biotechnology information gene expression database(NCBI-GEO),and R language soft-ware packages was used to analyze and screen differentially expressed genes(DEG)in different myocardial regions of myo-cardial infarction rats,as well as DEG of myocardial samples from patients with ischemic heart failure and healthy controls,and the regional expression of common genes was analyzed.Weighted gene co-expression network analysis(WGCNA)was used to screen the genes related to myocardial infarction and to carry out enrichment analysis,protein-protein interac-tion network(PPI)was constructed to screen core genes(HG).Results A total of 4 835 differentially expressed genes were screened out in myocardial infarction rats and normal controls,and 51 differentially expressed genes were screened out in ischemic heart failure patients and normal control samples,which revealed representative gene sets in the left ventricular myocardial infarction area(I area),border area(BZ area),and remote area(R area)after myocardial in-farction.Spatial expression analysis revealed that there were 20 co-expressed genes in each myocardial region,16 of which were expressed in all three regions,the number of genes specifically expressed in I,BZ and R regions were 2,0 and 2,respectively.Enrichment analysis showed that the functions of co-expressed genes were different in different region.The I and BZ regions were related to collagen fiber assembly,stress-induced cardiomyocyte hypertrophy,down-regulation of c-Jun amino terminal kinase(JNK signal)and cell proliferation,and complement signaling pathways;The I and R regions were enriched in the binding of Wnt and collagen;As a non-ischemic distal R region,the co-expressed genes were signifi-cantly enriched in the extracellular matrix for functions such as compressive resistance,cytolysis and inhibition of T cell proliferation.Furthermore,it was worth noting that the products of co-expressed genes in the three regions were mostly lo-cated in the extracellular space and extracellular matrix,suggesting that there may be active cellular secretion and interac-tion regulation.Further PPI analysis suggested that asporin(ASPN),osteoglycin(OGN)and collagentype ⅩⅥ alpha chain(COL14A1)gene might be the core genes of the mechanism mentioned above.Conclusions The common mechanism of ischemic heart failure in rats and human involves multiple signaling pathways such as complement and coagu-lation cascade signaling and Wnt;which may be closely related to cell apoptosis mediated by extracellular matrix and exo-somes;ASPN,OGN,and COL14A1 may be the core genes.This work is expected to provide spatial and pathway refer-ence for the selection of intervention targets and pathway in the transformation research related to ischemic heart failure.
