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.

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.

HBV DNA intra-and extracellularly, as well as the expression levels of intracellular HBV total RNAs and 3.5kb-RNA changes, were detected with qPCR. Hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) levels were measured in the cell supernatant by an enzyme-linked immunosorbent assay (ELISA). The t-test method was used for the statistical analysis of the mean difference between groups.Results:EFTUD2 mRNA and protein expression levels were significantly increased in HepAD38 and HepG2-NTCP cells following AM679 treatment, with a statistically significant difference ( P ?

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.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objectives:To report the sexual functional outcomes of vaginal dilation therapy in Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome patients.Methods:From March 2020 to February 2023, 97 MRKH syndrome patients performed vaginal dilation therapy with guidance from Peking Union Medical College Hospital, and 45 of them engaged in penetrative intercourse and were included in this prospective cohort study. The Chinese version of female sexual function index (FSFI) was used to assess sexual function. Functional success was defined as FSFI>23.45. Forty age-matched healthy women were selected as controls. Kaplan-Meier survival analysis was used to calculate the median time to success. Pearson correlation analysis was used to explore the relationship between neovagina length and sexual function. Complications were collected using follow-up questionnaires.Results:The functional success rate of vaginal dilation therapy was 89% (40/45) with a median time to success of 4.3 months (95% CI: 3.0-6.1 months). Compared to controls, MRKH syndrome patients had significantly lower scores in the orgasm domain (4.72±1.01 vs 4.09±1.20; P=0.013) and pain domain (5.03±0.96 vs 4.26±0.83; P<0.001). However, there were no significant differences in the FSFI total score (26.77±2.70 vs 26.70±2.33; P=0.912), arousal domain (4.43±0.77 vs 4.56±0.63; P=0.422) and satisfaction domain (4.88±0.98 vs 4.65±0.86; P=0.269) between MRKH syndrome patients and controls. MRKH syndrome patients had significantly higher scores in the desire domain (3.33±0.85 vs 3.95±0.73; P<0.001) and lubrication domain (4.37±0.56 vs 5.20±0.67; P<0.001). The prevalence of sexual dysfunction in MRKH patients was non-inferior to controls: low desire [3% (1/40) vs 23% (9/40); P=0.007], arousal disorder [3% (1/40) vs 3% (1/40); P>0.999], lubrication disorder [5% (2/40) vs 25% (10/40); P=0.012], orgasm disorder [40% (16/40) vs 20% (8/40); P=0.051], sexual pain [30% (12/40) vs 15% (6/40); P=0.108]. Conclusions:MRKH syndrome patients undergoing non-invasive vaginal dilation therapy could achieve satisfactory sexual life. Given its high functional success rate and slight complication, vaginal dilation therapy should be recommended as the first-line option, reducing the need for unnecessary surgeries.

ObjectiveTo investigate the possible mechanism of Wenfei Huaxian Decoction （温肺化纤汤） in treatment of pulmonary fibrosis in systemic sclerosis-associated interstitial lung disease （SSc-ILD）. MethodsSixty C3H/He female rats were randomly divided into a control group， a model group， a pirfenidone group， and low-， medium-， and high-dose Wenfei Huaxian Decoction groups. The SSc-ILD model mice was established by subcutaneous injection of bleomycin solution 0.04 mg/d into the back of mice for 28 days in all groups but the control group. After successful modelling， the pirfenidone group was given pirfenidone capsule 300 mg/（kg·d） by gavage， the low-， medium- and high-dose Wenfei Huaxian Decoction groups were given Wenfei Huaxian Decoction 7.81， 15.62， and 31.24 g/（kg·d） by gavage， respectively， and the control group as well as the model group were given normal saline 0.1 ml/10 g by gavage， for a total of 21 days. At the end of the intervention， HE staining and Masson staining were used to observe the pathological changes in the skin and lung tissues； the hydroxyproline content of the skin and lung tissues was detected； the protein expression levels of endoplasmic reticulum stress-related proteins glucose-regulated protein 78 （BIP） and C/EBP homologous protein （CHOP） as well as those of nuclear factor kappa B （NF-κB） pathway p65 were measured by western blot； ELISA was performed to determine the expression levels of interferon gamma （IFN-γ）， interleukin 6 （IL-6） and tumour necrosis factor alpha （TNF-α） in serum of rats. ResultsThe results of HE and Masson staining indicated that compared with the control group， the dermis significantly thickened， the number of collagen fibers significantly enlarged， and the number of inflammatory cells significantly increased in the model group； the lung tissue showed a marked inflammatory cellular response with massive collagen fibre proliferation with inflammatory cell infiltration. Compared with the model group， the skin tissue and lung tissue collagen fibre proliferation significantly reduced and inflammatory cell infiltration reduced in the pirfenidone group and all dose groups of Wenfei Huaxian Decoction， and the effects of pirfenidone group and Wenfei Huaxian Decoction medium- and high-dose groups were basically comparable. Compared with the model group， the content of hydroxyproline in skin and lung tissue， the serum level of IFN-γ， IL-6 and TNF-α， and the expression levels of BIP and CHOP protein in lung tissue increased in model group （P＜0.05）. Compared with model group， the content of hydroxyproline in skin tissue of pirfenidone group， low-and medium-dose Wenfei Huaxian Decoction groups decreased， and the content of hydroxyproline in lung tissue of medium-dose Wenfei Huaxian Decoction group decreased. The serum level of IFN-γ， IL-6， TNF-α and the expression levels of BIP， CHOP and p65 protein in lung tissue of rats in pirfenidone group and high-dose Wenfei Huaxian Decoction group decreased （P＜0.05）. The content of hydroxyproline in lung tissue of medium-dose Wenfei Huaxian Decoction group was significantly lower than that of low-dose and high-dose Wenfei Huaxian Decoction group， and the serum level of IFN-γ， IL-6， TNF-α in low- and medium-dose Wenfei Huaxian Decoction group were higher than those in high-dose Wenfei Huaxian Decoction group. The expression level of BIP protein in high-dose group was significantly lower than that in low- and medium-dose Wenfei Huaxian Decoction groups （P＜0.05）. ConclusionWenfei Huaxian Decoction can improve the skin and lung fibrosis of SSc-ILD rats， which may act through anti-inflammation， inhibition of NF-κB pathway， and then inhibition of endoplasmic reticulum stress， which ultimately blocked the fibrotic process.

ObjectiveTo analyze the correlation between 11 small molecule active components and 1 protein component of characteristic processed products with porcine cardiac blood and other products of Salviae Miltiorrhizae Radix et Rhizoma（SMRR） from Menghe medical school and anti-cerebral ischemic oxidative damage， and to identify its key component markers of characteristic processed products with porcine cardiac blood for anti-cerebral ischemic oxidative damage. MethodHigh performance liquid chromatography（HPLC） was established to simultaneously determine the contents of 11 active ingredients in SMRR and its processed products［processed with porcine cardiac blood， porcine blood， wine and transferrin（Tf） in porcine cardiac blood］， and the content of Tf in different processed products of SMRR was detected by enzyme-linked immunosorbent assay（ELISA）. Furthermore， A zebrafish ischemic stroke model was constructed to evaluate the effects of different processed products of SMRR on the behavioral trajectory of cerebral ischemic zebrafish， the neuronal damage of transgenic zebrafish Tg（elavl3：eGFP） brain， as well as the levels of malondialdehyde（MDA） and superoxide dismutase（SOD） in the brain tissues. The hippocampal neurons oxygen-glucose deprivation/reoxygenation（OGD/R）-induced ischemia-hypoxia model was constructed to evaluate the effects of different processed products of SMRR on oxidative damage of neuronal cells by taking lactate dehydrogenase（LDH）， reactive oxygen species（ROS）， MDA and SOD as indexes. Finally， principal component analysis（PCA）， partial least squares-discriminant analysis（PLS-DA） and Spearman correlation analysis were used to analyze the 11 small molecule active components and 1 protein component with efficacy indicators， in order to screen the key components of the characteristic processed products with porcine cardiac blood for cerebral ischemic oxidative damage. ResultCompared with the raw products， the contents of water-soluble and fat-soluble components in processed products of SMRR increased to different degrees， while the content of salvianolic acid A decreased. Compared with the wine-processed products， the contents of salvianolic acid B， danshensu， rosmarinic acid and other components in the porcine cardiac blood-processed products， porcine blood-processed products， Tf-processed products were increased， while the content of salvianolic acid A was decreased. ELISA results showed that there was no significant difference in Tf content between the porcine cardiac blood-processed products， porcine blood-processed products， Tf-processed products. Pharmacological results showed that different processed products of SMRR could improve the behavioral deficits， brain neuronal injury and oxidative stress after ischemic stroke in zebrafish， and the effect of the porcine cardiac blood-processed products was most pronounced. PCA results showed that salvianolic acid B， salvianolic acid A， rosmarinic acid， lithospermic acid， danshensu， tanshinone Ⅱ_A， caffeic acid， cryptotanshinone and tanshinone Ⅰ were the main contributing components of SMRR and its processed products. And the results of correlation analysis showed that the contents of cryptotanshinone， rosmarinic acid， caffeic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A and tanshinone Ⅰ were negatively correlated with MDA level in zebrafish brain tissue， while the contents of lithospermic acid， protocatechuic aldehyde， rosmarinic acid， dihydrotanshinone Ⅰ， salvianolic acid B and Tf were positively correlated with SOD level， and the contents of rosmarinic acid， caffeic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A， tanshinone Ⅰ， danshensu， Tf were positively correlated with neuronal fluorescence intensity in the zebrafish brain. And the contents of lithospermic acid， protocatechuic aldehyde， rosmarinic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A and Tf were negatively correlated with LDH， ROS and MDA levels and positively correlated with SOD level. ConclusionThere are differences in the anti-ischemic oxidative damage effects of SMRR and its different processed products， among which the porcine cardiac blood-processed products has the strongest effect on improving oxidative damage， which may be related to the content changes of salvianolic acid B， danshensu， rosmarinic acid and other components. This study can provide a basis for clarifying the quality markers of SMRR processed with porcine cardiac blood for cerebral ischemia and elucidating its processing mechanism.
