ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

ObjectiveTo explore the molecular mechanism implicated in the treatment of primary myelofibrosis （PMF） using Chinese medicinal herbs （CMH） by bioinformatics and molecular dynamics. MethodsData mining was performed to find the high-frequency CMH in treating PMF between the year of 1985 and 2024 by searching CNKI， Chinese Science and Technology Journal Database （CCD）， and China Academic Journal Database （CSPD）. TCMSP， SwissTargetPrediction and related reports were used to collect the main active ingredients of high-frequency CMH and their targets. The PMF datasets GSE44426 and GSE124281 were downloaded from GEO database， and R software was used for data normalization and differentially expressed genes （DEGs） screening. Key module hub genes were obtained by weighted gene co-expression network analysis （WGCNA） analysis. The common intersection genes of active ingredient targets， DEGs and key module hub genes of CMH were selected， and the target network was generated using Cytoscape 3.9.2 software. The core target network was generated by topological analysis， while key pathways were selected by GO and KEGG pathway enrichment analysis， and protein interaction relationships were obtained from the String database， so as to construct drug-ingredient-target network and protein interaction network （PPI） relationship diagrams. Discovery Studio 2020 software was used to perform molecular docking， and the GROMACS program was used to perform molecular dynamics simulation. ResultsA total of 21 prescriptions were collected involving 121 herbs. There were 9 herbs with a frequency ≥10 times， which were Danshen （Radix et Rhizoma Salviae Miltiorrhizae）， Huangqi （Radix Astragali）， Baizhu （Rhizoma Atractylodis Macrocephalae）， Danggui （Radix Angelicae Sinensis）， Dangshen （Radix Codonopsis）， Gancao （Radix et Rhizoma Glycyrrhizae）， Baishao （Radix Paeoniae Alba）， Fuling （Poria） and Shudihuang （Radix Rehmanniae Praeparata） from high- to low-frequency. A total of 98 active ingredients and 1125 potential targets were obtained from 9 high-frequency CMH. GSE44426 and GSE124281 data sets screened out 24 gene samples， including 14 of the healthy control group and 10 of the PMF group， and identified 319 DEGs between the two groups， including 122 up-regulated genes and 197 down-regulated genes. WGCNA screened out 24 co-expression module genes and found that the five modules closely related to the onset of PMF were MEpink， MEdarkred， MEblack， MEgrey， and MEturquoise， involving 7112 key module hub genes. The GO and KEGG enrichment analyses indicated that lipids and the atherosclerosis pathways were mainly involved in the mechanism of above high-frequency CMH in treating PMF， which included six hub protein targets： HSP90AA1， HSP90AB1， SRC， MAPK1， IL1B and IL10. From the drug-ingredient-target network， seven active ingredients of CMH targeting at these six hub targets were found， including verbascoside， verbascos isoflavone， kaempferol， luteolin， naringenin， quercetin and pachymic acid. The molecular docking and molecular dynamics analyses showed that the key CMH were Shudihuang， Huangqi， Baishao， Danshen， Gancao and Fuling， and among the seven active ingredients， calycosin had the highest binding affinity with HSP90AB1. ConclusionThe main CMH for the treatment of PMF may be Shudihuang， Huangqi， Baishao， Danshen， Gancao and Fuling， and the active ingredients include verbascoside， verbascos isoflavones， kaempferol， luteolin， naringenin， quercetin and pachymic acid. The relevant targets are HSP90AA1， HSP90AB1， SRC， MAPK1， IL-10， and IL-1β， and the most critical pathways are lipid and atherosclerosis pathways.

OBJECTIVE To systematically review the efficacy and safety of ticagrelor versus clopidogrel in CYP2C19 loss-of-function carriers with mild ischemic stroke or transient ischemic attack(TIA). METHODS Databases such as PubMed, Embase, the Cochrane Library, CNKI, and Wanfang were systematically searched, and the search period was from database establishment to June 2022. Two reviewers independently screened literature, extracted data, and evaluated the methodological quality of the included studies. Meta-analysis was performed using RevMan 5.3 software. RESULTS A total of 2 studies with 7 087 patients were included. Compared with clopidogrel, ticagrelor reduced the incidence of stroke[RR=0.78, 95%CI(0.66−0.93), I2=0%, P=0.007] and vascular event[RR=0.78, 95%CI(0.66−0.91), I2=0%, P=0.002] in patients with mild ischemic stroke or TIA carrying the CYP2C19 loss-of-function allele. The incidence of any bleeding[HR=2.18, 95%CI(1.66−2.85)] and minor bleeding[HR=2.41, 95%CI (1.81−3.20)] in the ticagrelor-aspirin group was higher than that in the clopidogrel-aspirin group, and dyspnea (1.2% vs 0.2%, P<0.001) and arrhythmias(1.7% vs 0.8%, P=0.001) were more common in the ticagrelor-aspirin group than in the clopidogrel-aspirin group. There was no significant difference in the incidence of severe bleeding between the two groups. CONCLUSION Compared with clopidogrel, ticagrelor reduces the incidence of stroke and vascular events in patients with mild ischemic stroke or TIA carrying the CYP2C19 loss-of-function allele, and did not increase the risk of severe bleeding. However, the ticagrelor group had a higher incidence of minor bleeding, dyspnea and arrhythmias.

Objective To investigate the correlation between serum interleukin-2 receptor(IL-2R),CD4+/CD8+ and disease activity in patients with lupus nephritis(LN).Methods A total of 38 patients with LN who were treated in Hangzhou Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University from March 2021 to December 2022 were enrolled in LN group,and 40 healthy persons who underwent physical examination in the hospital during the same period were included in healthy control group.General clinical data,systemic lupus erythematosus disease activity index(SLEDAI)and pathological classification were collected.LN patients were divided into active group and inactive group according to SLEDAI score,and the difference of clinical indicators between two groups was compared.Results The hemoglobin(Hb),platelet count,albumin(ALB),complement C3 and C4 in LN group were significantly lower than those in healthy control group,the positive rates of antinuclear antibody and anti-double strand DNA antibody(anti-ds-DNA antibody),serum creatinine(SCr)and C-reactive protein were significantly higher than those in healthy control group(P<0.05).The ALB of active group was significantly lower than that of inactive group,and IL-2R,erythrocyte sedimentation rate,24h urinary protein quantity and anti-ds-DNA antibody positive rate were significantly higher than those of inactive group(P<0.05).Serum IL-2R levels in LN patients were positively correlated with SLEDAI,SCr,blood urea nitrogen and 24h urinary protein quantity,and negatively correlated with Hb and complement C3(P<0.05).Conclusion Serum IL-2R can be used as an indicator to judge the degree of LN activity and provide a basis for the judgment of clinical disease activity.

Herb-induced liver injury(HILI)tends to have complex toxic material basis and toxic mechanism,which greatly affects the safety of traditional Chinese medicine.This article summarizes the main toxic components of Chinese herbal medicine causing liver injury and their mechanism of action.The toxic components of Chinese herbal medicine causing liver injury can be classified into two categories of drug-derived and non-drug-derived toxic components.Drug-derived toxic components mainly include alkaloids,terpenoids,anthraquinones,and phenylpropanoids,and their mechanism of action involves oxidative stress,apoptosis and necrosis,CYP450 enzymes,and genotoxicity.Non-drug-derived toxic components mainly include pesticide residues,sulfur dioxide residues,heavy metals,fungi,and plant growth regulators,and their mechanisms involve oxidative stress,apoptosis,metabolic disorders,and CYP450 enzymes.On this basis,this article further proposes the unsolved problems and research difficulties,in order to promote the basic research on the hepatotoxicity of traditional Chinese medicine.

Objective:To explore the influencing factors and pathways of home-based exercise rehabilitation compliance in patients after percutaneous coronary intervention (PCI), so as to provide theoretical basis for formulating targeted intervention program.Methods:From July 2022 to February 2023, convenience sampling was used to select 220 patients who underwent PCI at Yantai Yuhuangding Hospital affiliated with Qingdao Medical College, Qingdao University as the study subject. A survey was conducted on patients using the General Information Questionnaires, Self-Efficacy for Exercise Scale, Illness Perception and Behavior Questionnaire in Patients with Coronary Heart Disease after PCI, Social Support Rating Scale, and Exercise Rehabilitation Compliance Follow-up Scale.Results:A total of 220 questionnaires were distributed, and 215 valid questionnaires were collected, with an effective response rate of 97.73% (215/220). The Exercise Rehabilitation Compliance Follow-up Scale in 215 patients after PCI was (11.35±3.85). The mediating effect of exercise self-efficacy between social support and exercise compliance was 0.150 [95% CI (0.055, 0.167), P<0.01], and the mediating effect of disease cognition between social support and exercise compliance after PCI was 0.065 [95% CI (0.016, 0.090), P<0.05]. The direct effect of social support on exercise compliance was 0.238 [95% CI (0.064, 0.278), P<0.01], and the indirect effect was 0.215 [95% CI (0.083, 0.233), P<0.05], and the mediating effect accounted for 47.46% of the total effect. Conclusions:Social support can directly or indirectly affect the compliance of patients with home-based exercise rehabilitation through the mediating effect of exercise self-efficacy and post PCI disease cognition. Medical and nursing staff can improve patient exercise self-efficacy and disease cognition by constructing intervention strategies based on social support, thereby enhancing home-based exercise rehabilitation compliance.

The cases were mainly undertaken by the municipal health supervision institution, while the number of cases handled by basic-level health supervision institutions was increasing. The administrative penalties were mainly imposed on persons and primary or non-classified medical institutions. Common illegal behaviors included occupational health management of radiation workers and personal protection during medical exposure. Conclusion We should focus on strengthening the publicity and supervision of personal protection in occupational health management and medical exposure, continue to improve the law enforcement ability of basic-level radiation health supervisors, develop a standardized management system for radiation diagnosis and treatment, innovate the supervision mode and radiation hazard notification mode, promote the “Internet + ” informatization supervision, and recommend to improve and revise radiation-related laws and regulations.

Background/Aims: The accuracy of endosonographers in diagnosing gastric subepithelial lesions (SELs) using endoscopic ultrasonography (EUS) is influenced by experience and subjectivity. Artificial intelligence (AI) has achieved remarkable development in this field. This study aimed to develop an AI-based EUS diagnostic model for the diagnosis of SELs, and evaluated its efficacy with external validation. Methods: We developed the EUS-AI model with ResNeSt50 using EUS images from two hospitals to predict the histopathology of the gastric SELs originating from muscularis propria. The diagnostic performance of the model was also validated using EUS images obtained from four other hospitals. Results: A total of 2,057 images from 367 patients (375 SELs) were chosen to build the models, and 914 images from 106 patients (108 SELs) were chosen for external validation. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the model for differentiating gastrointestinal stromal tumors (GISTs) and non-GISTs in the external validation sets by images were 82.01%, 68.22%, 86.77%, 59.86%, and 78.12%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the external validation set by tumors were 83.75%, 71.43%, 89.33%, 60.61%, and 80.56%, respectively. The EUS-AI model showed better performance (especially specificity) than some endosonographers.The model helped improve the sensitivity, specificity, and accuracy of certain endosonographers. Conclusions We developed an EUS-AI model to classify gastric SELs originating from muscularis propria into GISTs and non-GISTs with good accuracy. The model may help improve the diagnostic performance of endosonographers. Further work is required to develop a multi-modal EUS-AI system.

ObjectiveTo explore the status of breastfeeding and complementary feeding of infants and toddlers at 6 and 12 months of age， and to analyze the related influencing factors to inform interventions for breastfeeding and complementary feeding problems in infants and toddlers. MethodsA total of 910 children selected from Pudong New Area of the Shanghai maternal-child pairs cohort， who completed follow-up at 6 and 12 months of age， were included in the study. A feeding status questionnaire completed by the parents was used to understand the breastfeeding and complementary feeding status of children at 6 and 12 months of age， and correlation analysis was conducted between the breastfeeding and complementary feeding status and the influencing factors. ResultsThe breastfeeding rate of infants at 6 months was 76.2% （693/909）， with a higher rate among girls than boys， and the rate of continuous breastfeeding at 12 months was 35.5% （322/906）. The minimum dietary diversity （MDD） pass rate at 6 months was 16.1% （146/906）， higher in boys than in girls （χ² =5.384， P<0.05）. The MDD pass rate at 12 months was 61.6% （554/899）. The likelihood of MDD failure in 6-month-old boys was 1.499 times higher than that in girls. Feeding of oils and their products， beverages （fruit juices）， and snacks （chocolates， candies， cakes， cookies， etc.） were risk factors for MDD failure in 6‒ and 12‒month-old children. Compared with no intake of oils and their products， beverage and snacks， the OR （95% CI） for MDD failure in 6-month-old infants fed with oils and their products， beverage and snacks were 5.866 （2.496‒13788）， 4.542 （2.943‒7.010）， and 2.599 （1.243‒5.261）， respectively. Compared with the non-fed group， the OR （95% CI） of MDD failure in infants aged 12 months fed with oils and their products， snacks， and sweet drinks were 2.335 （1.736‒3.140）， 1.549 （1.107‒2.168）， and 1.485 （1.116‒1.976）， respectively （P<0.05）. ConclusionsThe rate of continuous breastfeeding in children at 12 months in the Pudong New Area of Shanghai is low， and the dietary structure of children is unreasonable. Improvements are needed in the introduction of complementary foods. Unhealthy foods such as oils and their products， beverages， and snacks are all high-risk factors for MDD failure in children at 6 and 12 months.
