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:Rev-erbα is involved in the regulation of inflammation,but pharmacological activation of Rev-erbα increases the risk for cardiovascular diseases.To reduce the relevant risk,an exploration on SR9009,a Rev-erbα agonist,combined with other drugs to relieve inflammation in skeletal myoblasts was conducted,laying the theoretical foundation for the treatment of inflammation-associated skeletal muscle atrophy. OBJECTIVE:To investigate the relationship of SR9009,indolepropionic acid and nuclear factor-κB signaling pathways in lipopolysaccharide-induced C2C12 myoblasts. METHODS:(1)C2C12 myoblasts were induced to differentiate in the presence of lipopolysaccharide(1 μg/mL).RNA-seq and KEGG pathway analysis were used to study signaling pathways.(2)C2C12 myoblast viability was assessed using the cell counting kit-8 assay to determine optimal concentrations of indolepropionic acid.Subsequently,cells were categorized into control group,lipopolysaccharide(1 μg/mL)group,SR9009(10 μmol/L)+lipopolysaccharide group,indolepropionic acid(80μmol/L)+lipopolysaccharide group,and SR9009+indolepropionic acid+lipopolysaccharide group.ELISA was employed to measure protein expression levels of interleukin-6 in the cultured supernatant.Real-time quantitative PCR were employed to measure mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.Western blot assay were employed to measure protein expression levels of NF-κB p65 and p-NF-κB p65.(3)After Rev-erbα was knocked down by siRNA,knockdown efficiency was assessed by RT-qPCR.And mRNA levels of interleukin-6 and tumor necrosis factor α were also measured. RESULTS AND CONCLUSION:Compared with the blank control group,lipopolysaccharide time-dependently inhibited myofibroblast fusion to form myotubes,the mRNA expression levels of interleukin-6 and tumor necrosis factor α were elevated,and the level of interleukin-6 in the cell supernatant was significantly increased.The results of KEGG pathway showed that the nuclear factor-κB signaling pathway was activated by lipopolysaccharide.Indolepropionic acid exhibited significant suppression of C2C12 myoblasts viability when its concentration exceeded 80 μmol/L.Indolepropionic acid and SR9009 inhibited the activation of NF-κB signaling pathway,thereby played an anti-inflammatory role,and suppressed the mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.Compared with the lipopolysaccharide group,the ratio of p-NF-κB p65/NF-κB p65 protein expression were downregulated.SR9009 combined with indolepropionic acid notably reduced lipopolysaccharide-induced inflammation,further downregulated the mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.The ratio of p-NF-κB p65/NF-κB p65 protein expression was significantly lower than that in the SR9009+lipopolysaccharide group or indolepropionic acid+lipopolysaccharide group.Rev-erbα increases time-dependently with lipopolysaccharide induction.The knockdown efficiency of Rev-erbα by siRNA reached over 58%,and lipopolysaccharide was added after Rev-erbα was successfully knocked down.Compared with the lipopolysaccharide group,the mRNA expression levels of interleukin-6 and tumor necrosis factor α were significantly up-regulated.These results conclude that Rev-erbα may act as a promising pharmacological target to reduce inflammation.SR9009 targeted activation of Rev-erbα combined with indolepropionic acid significantly inhibits the nuclear factor-κB signaling pathway and attenuates the inflammatory response of C2C12 myofibroblasts.Moreover,the combined anti-inflammatory effect is superior to that of the intervention alone.

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.

Objective:To explore and analyze the expression levels of serum transthyretin（TTR）and Survivin in children with Mycoplasma pneumoniae pneumonia（MPP），and to further analyze the effect of the combination of the two in the predictive of pulmonary consolidation.Methods:A total of 142 children with MPP admitted to Qinhuangdao First Hospital from April 2022 to April 2024 were selected as the MPP group，and they were grouped into consolidation group（ n=58）and non-consolidation group（ n=84）according to the chest imaging examination.In addition，135 healthy children were selected as the control group.The ELISA was used to test serum TTR and Survivin levels on admission to the hospital.The general clinical data were collected and analyzed.Multivariate Logistic regression was used to analyze the influencing factors of pulmonary consolidation in children with MPP.Receiver operating characteristic（ROC）curves were plotted to analyze the value of TTR and Survivin in predicting pulmonary consolidation in children with MPP.Pearson method was used to analyze the correlation between TTR，Survivin and inflammation-related indicators. Results:Compared with the control group，the serum TTR[（261.25±28.06）mg/L vs.（296.33±31.28）mg/L] and Survivin[（1.53±0.18）pg/mL vs.（1.86±0.20）pg/mL] levels in the MPP group greatly decreased（ P<0.05）.Compared with the non-consolidation group，the serum TTR[（235.62±25.76）mg/L vs.（278.95±29.65）mg/L] and Survivin[（1.39±0.16）pg/mL vs.（1.62±0.19）pg/mL] levels in the consolidation group were greatly lower（ P<0.05），and the neutrophil percentage，white blood cell count and C-reactive protein（CRP）levels in the consolidation group were greatly higher than those in the non-consolidation group（ P<0.05）.Elevated neutrophil percentage，white blood cell count and CRP levels were risk factors for pulmonary consolidation in children with MPP（ P<0.05），while Elevated TTR and Survivin level were protective factors（ P<0.05）.The cutoff values for TTR and Survivin to diagnose solid lung lesions in children with MPP were 262.38 mg/L and 1.54 pg/mL,respectively.The area under ROC curve of TTR，Survivin and combined prediction for pulmonary consolidation were 0.855，0.866 and 0.940，respectively，and the area under ROC curve of combined prediction was greatly better than those of TTR（ Z=3.281， P=0.001）and Survivin（ Z=3.211， P=0.001）alone.TTR and Survivin were negatively correlated with neutrophil percentage，white blood cell count and CRP（ P<0.05）. Conclusion:The serum TTR and Survivin levels of children with MPP combined pulmonary consolidation are reduced，which have certain auxiliary predictive value for the occurrence of pulmonary consolidation in patients.

OBJECTIVE: To assess the clinical value of digital PCR (dPCR) for the prenatal diagnosis of common fetal aneuploidies. METHODS: A dPCR-based assay was developed for detecting trisomies 21, 18, and 13. A retrospective analysis was carried out on 173 amniotic fluid samples collected by the Prenatal Diagnosis Center of Taizhou Hospital between January 2017 and December 2023. By using chromosomal karyotyping as the gold standard, the diagnostic performance of the multiplex dPCR system was evaluated in a double-blind manner. This study has been approved by the Ethics Committee of Taizhou Hospital (Ethics No. K20250339). RESULTS: Chromosomal karyotyping has identified 59 cases of trisomy 21, 5 cases of trisomy 18, 2 cases of trisomy 13, 6 cases with chromosomal structural abnormalities or mosaicisms, and 101 cases with a normal karyotype. The dPCR results (Z-score cutoff = 4.0, CI = 99.997%) showed full concordance with karyotyping (sensitivity = 100%, specificity = 100%, Kappa = 1). Among the 6 structurally abnormal or mosaicism samples, dPCR has accurately detected 4 cases, but mis-classified 2 cases of trisomy 21 with very low-level mosaicisms (3.3%, 6.9%, respectively) as normal. CONCLUSION The established multiplex dPCR system demonstrated high diagnostic accuracy for common chromosomal aneuploidies, with results available within 24 hours. It can serve as an efficient supplementary tool to conventional chromosomal karyotyping, providing reliable support for time-sensitive clinical decision-making in prenatal diagnosis.

OBJECTIVE: To assess the clinical value of non-invasive prenatal testing (NIPT) for identifying maternal malignant tumors. METHODS: A retrospective analysis was carried out on pregnant women undergoing Non-invasive prenatal testing (NIPT) at Taizhou Hospital in Zhejiang Province from January 2018 to December 2022. The criteria included maternal copy number variations for at least two chromosomes. Clinical follow-up data were obtained for the high-risk population of maternal malignant tumors through telephone follow-up and review of electronic medical records. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: K20250339). RESULTS: Among 45 141 NIPT samples, 6 (0.013%) were suggested to have maternal malignant tumors. Follow-up information was available for 5 patients (83.3%). Two cases were diagnosed with maternal malignant tumors, including 1 myelodysplastic syndrome and 1 pelvic malignant tumor. Two cases were found to have multiple uterine fibroids and 1 was lost during follow-up. CONCLUSION The abnormal copy number indicated by NIPT may serve as an early signal for maternal malignant tumors. To establish a systematic follow-up protocol and multidisciplinary collaboration are conducive to achieving early diagnosis of tumors and improving the prognosis of patients. Based on the results of this study, it is recommended that for pregnant women with unexplained copy number variations and suspected maternal tumors by NIPT, targeted tumor screening program should be implemented to optimize their clinical management.

Objective:To analyze the values of platelet transforming growth factor-β (TGF-β) and SMAD family member 2 (Smad2) in patients′ peripheral platelets for CRC diagnosis and staging.Methods:Retrospective case-control study. Tumor tissues, paratumor tissues and peripheral blood samples were collected from 248 CRC patients (147 males, 101 females; age 21-93 years) diagnosed in the First Hospital of Jilin University from October 10th, 2020, to March 10th, 2025. Peripheral blood samples were also collected from 40 colorectal adenomatous polyp patients (21 males, 19 females; age 22-74 years) and 75 healthy individuals (43 males, 32 females; age 18-81 years) during the same period. Tissue homogenates and platelets were isolated using tissue disruption and gradient centrifugation, respectively. Total RNA was respectively extracted from tissues and platelets, and the expression levels of TGF-β and Smad2 were quantified by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) expressed as relative quantity 2 -ΔΔCt. Differences of TGF-β and Smad2 expression were compared between CRC tissues and adjacent tissues, as well as among CRC patients, polyp patients, and healthy controls. The relationship of platelet TGF-β and Smad2 expression with pathological features includingtumor stage, pathological type, and metastasis were analyzed. The efficiency of platelet TGF-β, Smad2, and their combination in diagnosing CRC was evaluated using receiver operating characteristic (ROC) curves. Results:The expression levels of TGF-β and Smad2 in CRC tumor tissues[1.09 (0.45, 2.00), 2.93 (0.78, 6.73)] were significantly higher than those in adjacent tissues[0.81 (0.27, 1.50), 1.29 (0.40, 2.63)] ( Z TGF-β=4.54, Z Smad2=6.67, both P<0.001). The expression levels of TGF-β and Smad2 in platelets of CRC patients[2.73(1.53, 4.38), 3.16 (1.58, 4.38)] were significantly higher than those in the colorectal polyp group[1.23(0.70, 2.54), 1.16(0.78, 2.27)] and the healthy control group[0.96(0.51, 1.88), 0.92 (0.55, 1.88)] ( H TGF-β=59.71, H Smad2=78.74, both P<0.001). Platelet TGF-β expression increased progressively with tumor stage (stage 1-4) ( P<0.05), while platelet Smad2 levels were higher in metastatic CRC compared with non-metastatic cases ( P<0.05). ROC curve analysis showed that the area under the curve (AUC) for diagnosing CRC when combining platelet TGF-β and Smad2 was 0.81[95%Confidence interval( CI) 0.77—0.86], which was 0.90 (95% CI 0.86—0.93) if adding serum carcinoembryonic antigen (CEA). Conclusion:Platelet TGF-β and Smad2 expression correlates with the diagnosis and staging of CRC, demonstrating potential as liquid biopsy biomarkers for colorectal malignancies.

CD46 is a type Ⅰ transmembrane glycoprotein that participates in the classical pathway and alternative complement activation cascade in the innate immune system. CD46 is highly expressed on the surface of various tumor cells，playing a significant role in promoting tumor progression and immune evasion. Studies have found that the expression level of CD46 is closely related to the prognosis and immunotherapy outcomes of multiple tumors. Inhibition of CD46 expression or function can enhance the sensitivity of tumor cells to oncolytic adenovirus therapy，among others. However，the clinical application of CD46 in tumor immunotherapy still faces some challenges. This review summarizes the research progress in CD46 in tumor immunotherapy，aiming to further explore the mechanisms of CD46 and the clinical potential of potential therapeutic targets.
