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 retrospectively analyze the epidemiological trends of birth defects in perinatal infants in Fengxian District, Shanghai from 2018 to 2022, so as to provide a scientific evidence for the formulation of related prevention and control strategies. MethodsBased on the data from the National Birth Defects Surveillance System, statistical analysis was conducted on the perinatal birth defects from monitored hospitals within the region from 2018 to 2022. ResultsFrom 2018 to 2022, a total of 20 870 perinatal infants delivered in the monitored hospitals in Fengxian District, with 472 cases with birth defects, showing a significant increase in the prevalence of birth defects (PRR=1.49, 95%CI: 1.39‒1.59). The risk of birth defects increased with maternal age, especially for advanced maternal age (PRR=1.58, 95%CI: 1.12‒2.25). Infants born to mothers with gestational diabetes had a higher prevalence of birth defects compared to those without gestational diabetes (PRR=1.99, 95%CI: 1.46‒2.70). Infants with birth defects were more likely to be born prematurely (PRR=2.07, 95%CI:1.56‒2.76). The top three types of birth defects were congenital heart disease (CHD), other anomalies of the external ear, and polydactyly. ConclusionThe prevalence of birth defects in Fengxian District monitored hospitals showed an upward trend from 2018 to 2022. Advanced maternal age and gestational diabetes were identified as risk factors for birth defects. CHD is the leading type of birth defect in Fengxian District over the five-year period. To reduce the prevalence of birth defects, it is crucial to implement comprehensive prevention and treatment measures for CHD.

Objective:To investigate the value of early tight junction protein Claudin-5 levels in predicting the severity of acute pancreatitis (AP).Methods:A prospective observational study was conducted, including patients diagnosed with AP and admitted to the Northern Jiangsu People's Hospital from December 1, 2021 to November 30, 2022. Eligible healthy volunteers were randomly selected to serve as healthy controls during the same period. Patients were classified into mild acute pancreatitis (MAP) group, moderate-severe acute pancreatitis (MSAP) group, and severe acute pancreatitis (SAP) group based on the 2012 Atlanta classification criteria. Patients with SAP were then divided into three subgroups of 1, 3, and 7 days based on the duration of hospitalization. Baseline data, such as gender, age, underlying disease, and probable etiology, was collected from all enrolled individuals. The enzyme-linked immunosorbent assay (ELISA) was employed to detect serum Claudin-5 levels in each cohort of enrollees. Data on additional serologic indicators, including hematocrit (HCT), albumin (Alb), serum Ca 2+, C-reactive protein (CRP), and procalcitonin (PCT) levels, were obtained via the in-hospital test query system in each group of patients with AP. The modified Marshall score (mMarshall), modified CT severity index (mCTSI) score, bedside severity index of severity in acute pancreatitis (BISAP) score, and acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) were recorded for each group of patients with AP. Differences in the above indicators between groups were analyzed and compared. Spearman's correlation method was employed to examine the relationship between Claudin-5 levels and each influential factor. The receiver operator characteristic curve (ROC curve) was plotted to analyze the predictive value of each influencing factor on SAP. Ridge regression was used to screen for independent risk factors for SAP. Results:A total of 109 patients with AP were enrolled, comprising 66 in the MAP group, 15 in the MSAP group, and 28 in the SAP group. Additionally, 27 healthy volunteers were enrolled as the healthy control group. No statistically significant differences were observed in gender and age among the enrolled groups, and no statistically significant differences were identified among the three groups of patients with AP in terms of underlying disease and etiologic composition. As the disease progressed, serum Claudin-5 levels exhibited a notable increase across all AP patient groups, and they were all significantly higher than those in the healthy control group [ng/L: 888.58 (574.52, 1 141.59), 3 749.02 (2 784.93, 5 789.92), 4 667.81 (3 935.21, 7 315.66) vs. 291.13 (250.19, 314.75), all P < 0.05]. Subgroup analyses showed that as the disease duration prolonged, patients in the SAP group exhibited a notable decline in Claudin-5 levels at 3 days post-admission, compared with those at 1 day post-admission [ng/L: 2 052.59 (1 089.43, 4 006.47) vs. 4 667.81 (3 935.21, 7 315.66), P < 0.05]. Spearman correlation analysis showed that serum Claudin-5 levels in patients with AP were significantly positively correlated with CRP, PCT, HCT, and mMarshall, mCTSI, and BISAP scores ( r values were 0.570, 0.525, 0.323, 0.774, 0.670, 0.652, all P < 0.001), and significantly negatively correlated with Alb ( r = -0.394, P < 0.001). A significant trend was observed in patients with AP, with an increase of HCT levels and a decrease of Alb levels as the disease progressed (both P < 0.05). An improvement of aforementioned phenomena was observed in patients with SAP following treatment, indirectly indicating that serum Claudin-5 level was a positive indicator of vascular leakage. ROC curve analysis showed that serum Claudin-5 levels in patients with AP exhibited the highest accuracy for early prediction of SAP, with the area under the ROC curve (AUC) of 0.948. When serum Claudin-5 levels ≥2 997 ng/L, the sensitivity for early screening for SAP was 100% and the specificity was 88.89%. Multifactorial ridge regression analysis showed that serum Claudin-5 level, PCT and APACHEⅡscore could be used as independent risk factors for early prediction of SAP (all P < 0.05). Conclusion:Serum Claudin-5 levels facilitate early prediction of SAP and are strongly associated with inflammatory response and vascular leakage.

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 investigate the prevalence and mortality of dementia and assess the impact of geriatric syndromes (GS) on the risk for dementia and death in elderly population in Beijing.Methods:A cross-sectional survey was conducted in the elderly population aged ≥65 years and selected by a multi-stage sampling in Beijing during 2013-2015. Cognitive function was screened using the Chinese Revised Version of the Mini-Mental State Examination (MMSE). Then, neurological examination and psychiatric assessment were performed for those with the MMSE score lower than the cut-off value. The information about GS prevalence was also collected. The study also collected death records for all individuals from baseline until December 31, 2019. Based on the age and gender distribution from Beijing data of the 2010 Six th National Population Census, the dementia prevalence in the study population was directly standardized. Logistic regression analysis was used to evaluate the association of different forms of dementia with GS, and Cox proportional hazards regression model was used to estimate the hazard ratio ( HR) and 95% CI of death. Results:During 2013-2015, a total of 2 935 individuals completed dementia assessments, of which 167 were diagnosed with dementia. The standardized prevalence of dementia was 5.9% (95% CI: 5.0%-17.4%). The individuals with Alzheimer's disease (AD) and vascular dementia (VaD) accounted for 58.7% and 28.1% of total individuals with dementia, respectively. Aging, lower education level, urinary incontinence, and fall were risk factors for AD, while disability of activity of daily life dependence, hypertension, and stroke were found to be risk factors for VaD. After a median follow-up of 5.44 person-years, 399 deaths were recorded. The 5-year mortality risk was 2.87 (95% CI: 1.92-4.17) times and 4.93 (95% CI: 3.23-7.53) times higher for the elderly individuals with AD and VaD, respectively, compared to non-demented individuals. After adjusting for demographic, GS, and cardiovascular risk factors, the mortality risk in the elderly individuals with AD showed no significant difference compared with non-demented individuals ( HR=1.32, 95% CI: 0.89-1.97), while the mortality risk in those with VaD was 2.46 (95% CI: 1.49-4.05) times higher than that in non-demented individuals. Conclusions:The prevalence of dementia in Beijing increased significantly in the context of population aging, especially the prevalence of AD. The presence of GS increased the risks for AD and VaD, as well as the risk for death. Close attention needs to be paid to GS management in dementia prevention in elderly population.

Objective: To investigate the differences in enolase and laminin levels in vaginal epithelial tissues between mice successfully infected withGardnerellaand mice not infected with Gardnerella, providing information for further exploration of the correlation between enolase and laminin levels and the incidence of bacterial vaginosis. Methods: Gardnerella strains isolated, purified, and identified from vaginal secretions of patients with bacterial vaginosis were used to infect the vagina of mice and establish a mouse model of bacterial vaginosis. Successful and failed mice was defined as successful and failed groups, respectively. Differential expression of enolase and laminin in the vaginal epithelial tissue of two groups of mice was detected by Western blot. Modeling success rate was statistically analyzed, and the expression differences of enolase and laminin was compared between two groups. Results: One strain of Gardnerella vaginalis infected 10 SPF grade KM mice, 7 mice met the diagnostic criteria for bacterial vaginosis, and 3 mice failed to model, with a success rate of 70%. Western blot was used to detect protein expression levels, and the levels of laminin and enolase in the successfully modeled mouse vaginal epithelial tissue were significantly higher than those in the failed modeling group, with statistical differences between the two groups(P<0.05). Conclusion Enolase and laminin may be involved in the occurrence of bacterial vaginosis, however, further research is needed to determine the mechanisms through which they trigger the occurrence and development of the disease.

Objective:To investigate the relationship between serum soluble CD155 (sCD155), soluble CD163 (sCD163) and chemotherapy efficacy and prognosis in patients with diffuse large B-cell lymphoma (DLBCL).Methods:A total of 126 patients with DLBCL admitted to Handan Central Hospital from May 2018 to May 2020 (DLBCL group) and 126 healthy subjects (control group) were prospectively selected to compare serum sCD155 and sCD163 levels. According to the chemotherapy effect of DLBCL patients, they were divided into effective group and ineffective group, and the serum sCD155 and sCD163 levels were compared before and after treatment. The effective rate of chemotherapy in patients with different serum sCD155 and sCD163 levels was compared. Kaplan-Meier method was used to analyze the relationship between serum sCD155 and sCD163 levels and 3-year overall survival (OS) and progression-free survival (PFS) of DLBCL patients. Cox proportional risk regression model was used to analyze the prognostic factors of DLBCL patients.Results:The serum levels of sCD155 and sCD163 in DLBCL group were higher than those in control group before treatment (all P<0.05). The effective rate of chemotherapy in 126 DLBCL patients in this group was 69.8%(88/126). Compared with the effective group, the serum levels of sCD155 and sCD163 were higher in the ineffective group before and after treatment (all P<0.05). Compared with before treatment, serum sCD155 and sCD163 levels in the effective group were decreased after treatment (all P<0.05). The effective rate of DLBCL patients in sCD155 and sCD163 high level groups was lower than that in sCD155 and sCD163 low level groups (all P<0.05). Kaplan-Meier analysis showed that the 3-year OS and PFS of DLBCL patients in the low level group of sCD155 and sCD163 were higher than those in the high level group (all P<0.05). The high level of sCD155 and sCD163 were independent risk factors for 3-year PFS and OS in DLBCL patients (all P<0.05). Conclusions:Abnormal levels of serum sCD155 and sCD163 in DLBCL patients may reduce the efficacy of chemotherapy and lead to poor prognosis.

Objective:To analyze the clinical characteristics and all-cause mortality influencing factors of patients with Keshan disease.Methods:Clinical data of patients with Keshan disease from Keshan disease areas in Sichuan Province and Yunnan Province were collected and retrospectively analyzed for clinical characteristics and survival status during regular follow-up. According to the survival status of patients, the survey subjects were divided into a survival group and a death group. All-cause mortality (referring to the death caused by various reasons throughout the follow-up period) was used as the study endpoint. Kaplan-Meier (K-M) survival curve analysis and log-rank χ 2 test were performed, univariate and multivariate Cox regression analysis were used for all-cause mortality factor analysis. Results:A total of 176 patients with Keshan disease were collected, including 92 cases in Sichuan Province and 84 cases in Yunnan Province. Among all the patients, there were 105 males, accounting for 59.66%, and 71 females, accounting for 40.34%. The age was (53.89 ± 13.19) years old. Thirty-five cases died from all causes, with a mortality rate of 19.89%. There were significant differences in age ( t = 2.09, P = 0.038), New York Heart Association (NYHA) cardiac function grading (χ 2 = 14.62, P < 0.001) and ventricular premature contraction (χ 2 = 6.82, P = 0.009) between the survival group and the death group. K-M survival curve analysis showed that patients with Keshan disease complicated by premature ventricular contraction and high NYHA cardiac function grading (Ⅲ and Ⅳ) had higher all-cause mortality (log-rank χ 2 = 8.72, 22.49, P < 0.05). Univariate Cox regression analysis showed that NYHA cardiac function grading and ventricular premature contraction ( HR = 3.09, 2.71, P < 0.05) were predictive influencing factors for all-cause mortality in patients with Keshan disease. Multivariate Cox regression analysis showed that NYHA cardiac function grading ( HR = 6.57, P = 0.002) and ventricular premature contraction ( HR = 2.98, P = 0.050) were independent factors for all-cause mortality in patients with Keshan disease. Conclusions:Among 176 patients with Keshan disease, the number of patients with poor cardiac function (NYHA cardiac function grading Ⅲ and Ⅳ) and arrhythmia is high. NYHA cardiac function grading and ventricular premature contractions are independent influencing factors for all-cause mortality in patients with Keshan disease.

Objective:To analyze the clinical characteristics, prognosis and gene mutation in patients with dilated cardiomyopathy (DCM) in Keshan disease area of Sichuan Province, and to explore the risk factors for all-cause death in DCM patients.Methods:In June 2016, 55 DCM patients diagnosed at the local disease prevention and control center through clinical manifestations, electrocardiogram examination, and echocardiography were selected as the survey subjects in Mianning County, Liangshan Yi Autonomous Prefecture, and Renhe District, Panzhihua City, Keshan disease areas of Sichuan Province. Baseline clinical data were analyzed and long-term follow-up was conducted. The follow-up period ended June 15, 2021, with the endpoint of all-cause death. Univariate Cox regression was used to analyze the influencing factors of all-cause death in patients, and Kaplan-Meier (K-M) survival curve was used to analyze the survival time of patients. At the same time, peripheral venous blood was collected from 27 DCM patients. After separating white blood cells, DNA was extracted, and whole exome sequencing was performed to screen potential pathogenic genes.Results:Among the 55 DCM patients, 40 were males and 15 were females. The age was (54.09 ± 12.38) years old. The heart function classification of New York Heart Association (NYHA) was mainly grade Ⅱ and Ⅲ, accounting for 94.55% (52/55). The follow-up time for 55 DCM patients was (7.02 ± 2.96) years, and 17 patients experienced all-cause death, accounting for 30.91% (17/55), including 15 males and 2 females. Compared with the survival group, the death group had a lower incidence of syncope (χ 2 = 6.57, P = 0.010), but higher rates of bilateral lower limb edema (χ 2 = 6.43, P = 0.017), pulmonary congestion (χ 2 = 7.61, P = 0.006), intraventricular conduction block (χ 2 = 6.41, P = 0.011), and angiotensin-converting enzyme inhibitor (ACEI) use (χ 2 = 6.57, P = 0.010), as well as increased left ventricular diameter ( t = 2.36, P = 0.022). Univariate Cox regression analysis showed that bilateral lower limb edema [hazard ratio ( HR) = 4.61, P = 0.042] and intraventricular conduction block ( HR = 3.20, P = 0.019) were risk factors for all-cause death of DCM patients. The results of K-M survival curve analysis showed that patients with bilateral lower limb edema and intraventricular conduction block had higher all-cause death rates (log-rank χ 2 = 5.02, 6.24, P = 0.025, 0.012). Whole exome sequencing results showed that 4 patients were detected to carry pathogenic or suspected pathogenic gene mutations, with a positive rate of 14.81% (4/27), involving three genes: β-myosin heavy chain 7 (MYH7), calreticulin 3 (CALR3), and gelsolin (GSN). Conclusions:The all-cause death rate of DCM patients in the Keshan disease area of Sichuan Province is relatively high. Dead patients are prone to bilateral lower limb edema, pulmonary congestion, and intraventricular conduction block, as well as increased left ventricular diameter. Bilateral lower limb edema and intraventricular conduction block are independent predictive risk factors for all-cause death in DCM patients. MYH7, CALR3 and GSN are involved in the pathogenesis of DCM.

Objective:To investigate the impacts of magnesium isoglycyrrhetinic acid combined with continuous blood purification on organ function and inflammatory mediator levels in patients with severe acute pancreatitis (SAP) complicated with sepsis.Methods:A total of 124 patients with SAP complicated with sepsis who came to Subei People′s Hospital from March 2020 to February 2023 were grouped into an observation group (62 cases) and a control group (62 cases) according to the treatment method, the control group was treated with continuous blood purification, and the observation group was treated with magnesium isoglycyrrhetate on basis of the control group, the organ function, inflammatory mediator levels, clinical efficacy, and clinical medication safety of two groups were compared.Results:After treatment, the scores of acute physiology and chronic health status assessment (APACHE) Ⅱ and sequential organ failure assessment (SOFA) in both groups were decreased compared to before treatment, and the scores of APACHE Ⅱ and SOFA in the the observation group were lower than those in the control group: (26.43 ± 3.78) scores vs. (35.99 ± 3.87) scores, (9.18 ± 1.52) scores vs. (14.51 ± 1.88) scores, there were statistical differences ( P<0.05). After treatment, the levels of interleukin (IL)-8, tumor necrosis factor-α (TNF-α) and IL-6 in both groups were decreased, and the levels of IL-8, TNF-α and IL-6 in the the observation group were lower than those in the control group: (114.81 ± 23.74) ng/L vs.(268.32 ± 29.14) ng/L, (214.41 ± 25.09) ng/L vs. (311.33 ± 28.11) ng/L, (32.58 ± 4.76) ng/L vs. (46.35 ± 5.76) ng/L, there were statistical differences ( P<0.05). The total clinical effective rate after treatment in the the observation group was higher than that in the control group: 96.77%(60/62) vs. 80.65%(50/62), there was statistical difference ( χ2 = 6.52, P<0.05). The incidence of adverse reactions in the two groups had no statistical difference ( χ2 = 0.08, P>0.05). Conclusions:Magnesium isoglycyrrhetinic acid combined with continuous blood purification can improve organ function and reduce inflammatory mediator levels in SAP patients with sepsis.
