ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Background: Influenza A virus (IAV) is a negative-sense RNA virus of the Orthomyxoviridae family and is the etiological agent of a highly contagious acute respiratory disease that can lead to acute lung injury. Objective: To elucidate the molecular mechanisms of IAV infection, an integrative research approach combining gene expression profiling, multinetwork analysis, and in vivo experimental validations was employed. Methods: First, a series of network-based analyses were performed, including protein-protein interaction network construction, weighted gene co-expression network analysis, and subsequent gene set enrichment analysis, to identify the major underlying mechanisms of IAV infection. Following gene expression analysis, core targets, both direct and indirect regulators, were screened. An IAV (H1N1) strain A/PR/8/34-induced acute lung injury mouse model was constructed for in vivo validations. Batch one included two groups to evaluate findings from the multi-network analysis: Mock (n = 10; 5 males and 5 females) and IAV (n = 10; 5 males and 5 females). Batch two included three groups to assess the role of toll-like receptor 3 (TLR3) in IAV infection: Mock (n = 6; 3 males and 3 females), IAV (n = 6; 3 males and 3 females), and TLR3 inhibitor (n = 6; 3 males and 3 females). Body weight was measured on days 0, 3, and 5 after infection. On day 5, lung tissues were collected to assess viral load and histopathological changes. Key targets were examined using enzyme-linked immunosorbent assay, Western blotting, and immunofluorescence staining, both in sera and lung tissues. Results: IAV infection was significantly associated with dysregulation of the immune-inflammation system, such as the LTR, nucle-otide-binding oligomerization domain-(NOD) like receptor, retinoic acid-inducible gene I-like receptor, and nuclear factor kappa-B signaling pathways. Gene set enrichment analysis further indicated that the TLR and necroptosis signaling pathways played crucial roles in the progression of IAV infection (TLR signaling pathway normalized enrichment score = 2.3941, P = 1.00 × 10 ⁻¹⁰; necroptosis normalized enrichment score = 1.9421, P = 6.21 × 10 ⁻⁷). Among the core targets, TLR3 and mixed lineage kinase domain-like protein (MLKL) may regulate gene expression at the transcriptional level (all P < 0.05). In vivo validation using an IAV (PR8) infected acute lung injury mouse model demonstrated increased viral load and lung index, alveolar structural damage, and inflammatory cell infiltration. Immunofluorescence staining exhibited large gaps in Lamin B1 staining and breaches in Emerin signals following IAV-PR8 infection. Expression levels of TLR3, p-receptor-interacting serine/threonine-protein kinase 3 (RIPK3)/RIPK3, and p-mixed lineage kinase domain-like protein (MLKL)/MLKL proteins in lung tissues, as well as proinflammatory factors and mediators in sera, were significantly elevated after IAV infection. Moreover, enhanced neutrophil infiltration (myeloperoxidase) and citrullinated histone H3 (a neutrophil extracellular trap-specific marker), both established indicators of neutrophil extracellular trap formation, were observed. Notably, treatment with a TLR3 inhibitor significantly ameliorated IAV-induced acute lung injury by regulating necroptosis-related targets. Conclusion: Our study provides network-based in vivo evidence that TLR3-receptor-interacting serine/threonine-protein kinase 3-MLKL-mediated necroptosis may underlie IAV-induced acute lung injury and could serve as a potential therapeutic target in severe influenza cases.

Gallbladder cancer is a highly aggressive malignancy of the biliary system, often diagnosed at the advanced stage due to its insidious early symptoms, leading to poor overall progno-sis. In recent years, the rapid advancement of artificial intelligence (AI) technologies and their inte-gration into medicine have opened new avenues for the early diagnosis and precision treatment of gallbladder cancer. Currently, AI incorporating deep learning algorithm has significantly improved diagnostic sensitivity and specificity in ultrasound, computed tomography, and pathological analysis. However, clinical translation of AI models remains limited by challenges such as insufficient annota-ted data and limited model interpretability. Future research should focus on establishing multi-center data-sharing mechanisms, developing interpretability tools, and optimizing multimodal data integration strategies, thereby promoting the transformation of AI technologies from an auxiliary diagnostic tool to a core component of clinical decision-making.

Objective To investigate the prognostic differences among pure urothelial carcinoma,squamous-differentiated urothelial carcinoma,and pure squamous cell carcinoma,so as to provide reference for postoperative risk stratification.Methods The clinical data of bladder cancer patients who visited the Department of Urology,Peking University First Hospital and underwent radical cystectomy during Jan.2005 and Jun.2024 were retrospectively analyzed.Patients were categorized into the pure urothelial carcinoma group(n=725),squamous-differentiated urothelial carcinoma group(n=189),and pure squamous cell carcinoma group(n=36).General characteristics,surgical approaches,pathological staging,muscle invasion status,and lymph node positivity were compared among the three groups.Kaplan-Meier survival curves were plotted,and prognostic differences among the groups were compared after 1∶1 propensity score matching between each pair.Independent risk factors of prognosis were identified with Cox multivariable regression.Results The pure squamous cell carcinoma group had a higher proportion of female patients(50.00％vs.25.24％vs.22.75％,P=0.002 4).Compared with the pure urothelial carcinoma group,the other two groups demonstrated higher proportions of stage Ⅲ+Ⅳ,higher rates of muscle invasion,and higher lymph node positivity,with the pure squamous cell carcinoma group showing the highest overall staging(69.45％vs.58.20％vs.29.38％,P＜0.000 1).Kaplan-Meier analysis showed that squamous-differentiated urothelial carcinoma group and pure squamous cell carcinoma group had significantly worse survival than the pure urothelial carcinoma group(P＜0.05),while the former two groups exhibited similar outcomes(P=0.85).After propensity score matching,postoperative survival curves among the three groups were not significantly different(all P＞0.05).In multivariable Cox proportional hazards models adjusting for confounders,prognosis was primarily associated with age,muscle invasion,and lymph-node positivity(P＜0.05);pathological subtype was not an independent predictor of postoperative survival.Conclusion In a cohort of non-metastatic patients undergoing radical cystectomy,pure squamous cell carcinoma and squamous-differentiated urothelial carcinoma presented with higher clinical and pathological staging and poorer unadjusted prognosis compared with pure urothelial carcinoma.However,postoperative survival did not differ significantly among the three groups in the same clinicopathological conditions.

Purpose To explore the influence of thrombolysis therapy before percutaneous coronary intervention(PCI)on long-term left ventricular global and regional function in ST segment elevation myocardial infarction(STEMI)patients by cardiac magnetic resonance(CMR).Materials and Methods A retrospective analysis was conducted on 67 STEMI patients who were enrolled in a prospective study from November 2021 to August 2022 in the First Affiliated Hospital with Nanjing Medical University,the First People's Hospital of Lianyungang,the Affiliated Hospital of Jiangnan University,Changzhou No.2 People's Hospital and Huai'an Second People's Hospital and underwent CMR examination one year later.STEMI patients were divided into thrombolysis group and non-thrombolysis group according to whether a single half-dose of 5 mg recombinant staphylokinase(r-SAK)was given within two hours before the first medical contact and PCI.Based on CMR cine images,the traditional left ventricular function,global and segmental functional parameters were measured,and the differences between the two groups were compared.According to the degree of late gadolinium enhancement involvement,myocardial segments were divided into the following four types:transmural infarcted segments,non-transmural infarcted segments,locally infarcted segments,and non-infarcted segments.The parameters of the two groups were compared across these different segments.Results At the patient level,the cardiac index,left ventricular wall thickening and left ventricular wall motion in r-SAK thrombolysis group were higher than those in non-thrombolysis group(t/Z=-2.426,-4.307,-2.735,all P<0.05).At the segment level,compared with non-thrombolysis group,patients received r-SAK before primary PCI showed greater segmental radial strain in non-transmural infarcted segments(Z=-2.117,P=0.034);larger segmental wall motion in locally infarcted segments(Z=-2.235,P=0.025),and better segmental circumference strain in the non-infarcted segments(Z=-3.869,P<0.001).Conclusion The thrombolytic therapy before PCI in STEMI patients retain better long-term left ventricular global and regional function evaluating by CMR.

Background and purpose:SEC14L1P1,a pseudogene of the SEC14 family,is closely associated with the development of various tumors,but its role in oral squamous cell carcinoma(OSCC)has not been clarified.This study aimed to gain insights into the expression characteristics and subcellular localization of SEC14L1P1 in OSCC cells,as well as its effects on OSCC cell proliferation and migration.Methods:The expression of SEC14L1P1 in head and neck squamous cell carcinoma(HNSCC)tissues was analyzed by the ENCORI database;The expression of SEC14L1P1 and its relationship with patient prognosis in HNSCC was further analyzed using the GDC and UCSC Xena databases.The expression of SEC14L1P1 in OSCC cell lines was detected by real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR);RNA nucleoplasmic separation assay was performed to determine the localization of SEC14L1P1 in OSCC cells.SEC14L1P1 knockdown(SS-SEC14L1P1)group and knockdown control(SS-NC)group were established for CAL-27 cells,and SEC14L1P1 overexpression(SEC14L1P1)group and overexpression control(Vector)group were established for HN30 cells.The effects of SEC14L1P1 expression on the proliferation and migration abilities of cells in each group were assessed by cell counting kit-8(CCK-8)and transwell migration assays.RTFQ-PCR and Western blot experiments were used to detect the effects of altered SEC14L1P1 expression on the expression levels of epithelial-mesenchymal transition(EMT)-related genes.To investigate the effects of SEC14L1P1 on the proliferation of OSCC cells in vivo using a subcutaneous xenograft tumor model in nude mice,12 four-week-old BALB/c nude mice were randomly divided into two groups:the antisense oligonucleotide(ASO)-NC group and the ASO-SEC14L1P1 group,with 6 mice in each group.All mice were individually labeled.Further mechanistic studies were performed by analyzing molecules interacting with SEC14L1P1 through the RNAInter database,and the ENCORI database was queried for expression correlation between SEC14L1P1 and DHX9.The effect of altered SEC14L1P1 expression on the phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)pathway was detected by Western blot assay.Results:Database analysis showed that the expression of SEC14L1P1 was higher in HNSCC tissues than in normal tissues,and was strongly associated with poor patient prognosis.The RTFQ-PCR results showed that SEC14L1P1 was highly expressed in all six OSCC cell lines;RNA nucleoplasmic separation showed that SEC14L1P1 was mainly localized in the nucleus in CAL-27 and HN30 cells.Compared with SS-NC,the relative expression of SEC14L1P1 in the SS-SEC14L1P1 group was significantly lower and significantly inhibited cell proliferation and migration,while the relative expression of SEC14L1P1 in the SEC14L1P1 group was significantly higher compared with the Vector group,which also significantly increased cell proliferation and migration.The down-regulation of SEC14L1P1 was accompanied by increased mRNA and protein levels of E-cadherin,and decreased mRNA and protein levels of N-cadherin and vimentin,with the opposite result after SEC14L1P1 overexpression.In vivo experiments showed that the xenograft tumor weight and volume of the ASO-SEC14L1P1 group were significantly reduced.Further mechanistic studies revealed a positive correlation between SEC14L1P1 and DHX9 expressions,and DHX9 has been shown to activate the PI3K/AKT signaling pathway.Knockdown of SEC14L1P1 resulted in decreased protein expressions of phosphorylated-PI3K(p-PI3K)and phosphorylated-AKT(p-AKT),and overexpression of SEC14L1P1 increased protein expressions of p-PI3K and p-AKT.Conclusion:SEC14L1P1 showed high expression levels in OSCC cells and tissues and promoted the proliferation and migration of OSCC cells,a phenomenon that may be related to the regulation of the PI3K/AKT signaling pathway by SEC14L1P1,which in turn promotes EMT.

Objective:To design two kinds of intensity modulated radiotherapy (IMRT) plans with different radiation field distributions,and to compare the dose differences of that at the dose of target region and organs at risk (OAR) for middle and lower esophageal cancer,so as to provide a reference for the design of IMRT plan. Methods:The data of 17 patients with middle and lower esophageal cancer who received IMRT at Shangluo Central Hospital from November 2022 to May 2023 were retrospectively analyzed. IMRT plans with different radiation fields for Plan 1 and Plan 2 were designed for each patient. The angles of radiation field for Plan 1 were 0°,80°,120°,160° and 200°,and those for Plan 2 were 30°,130°,180°,230° and 330°,respectively. The prescribed dose to the planning target volume (PTV) was 60 Gy/30 F. The differences in dosimetric parameters between the two plans were compared. Results:There were no statistically significant differences in the dose parameters of 2％,98％,50％ target dose (D2％,D98％,D50％),homogeneity index (HI),conformity index (CI) and monitor unit between the two groups (P>0.05). There were no significant differences in V5 of dual lungs,the mean dose (Dmean) of heart,and the maximum dose (Dmax) of spinal-cord between two groups (P>0.05). The volume percentage (V10,V20,V30) of dual lungs received radiation doses of 10,20 and 30 Gy,and the mean dose (Vmean) of lung in the Plan1 group reduced respectively 7.44％,21.16％,10.09％ and 5.31％ than those in the Plan2 group,and the differences of them were statistically significant (t=-5.845,-7.729,-2.247,-3.960,P<0.05). Heart V10 and V20 in the Plan1 group decreased respectively by 7.23％ and 5.78％,with statistical significance (t=-4.376,-3.523,P<0.01),while V30 and V40 of Plan 1 increased respectively by 2.7％ and 4.92％,without statistical significance (P>0.05). There was no significant difference in heart Dmean between the Plan1 group and the Plan2 group (P>0.05). Conclusion:Both two methods of distribution field can meet the clinical requirements,and Plan1 has more advantages in protecting organs at risk under the premise of meeting the requirements of target region.
