Objective To comprehensively evaluate the multidimensional impact of the"Tianjin Experience"of Chest Pain Center(CPC)development on in-hospital mortality,optimization of treatment workflows,and regional coordination of care for patients with acute myocardial infarction(AMI),with the aim of providing scientific evidence to further improve the model and enhance AMI treatment outcomes.Methods This study analyzed data from the"Cardiovascular and Cerebrovascular Acute Events Surveillance System"maintained by the Tianjin Center for Disease Control and Prevention from 2013 to 2024.A segmented regression model was applied to assess the long-term trends in in-hospital mortality from acute myocardial infarction(AMI),with a particular focus on evaluating the impact of the chest pain center program on treatment outcomes.Additionally,supplementary analyses were conducted using surveillance data from the Tianjin Chest Pain Center Quality Control Team between 2017 and 2024.To verify the effectiveness of treatment process optimization,temporal trends in key time-based process indicators were assessed,including Door-in-Door-out(DIDO)time at non-PCI hospitals,Door-to-Wire(D-to-W)time,and First Medical Contact to Wire(FMC-to-W)to wire time.Results According to the data from the Tianjin Center for Disease Control and Prevention,the average 28-day AMI mortality rate in the overall patient population was 9.85％.Between 01/2013 and 12/2014,the mortality rate showed a significant upward trend(P＜0.01),followed by a downward trend from 01/2015 to 12/2024,although the latter did not reach statistical significance(P＞0.05).From 2013 to 2024,a total of 27 633 AMI cases with complete clinical records were collected from Tianjin Chest Hospital,with an average 28-day mortality rate of 4.55％.The mortality rate exhibited a decreasing trend from 01/2013 to 12/2016,with an annual percent change(APC)of-7.56(P＜0.05).From 01/2017 to 12/2024,the trend stabilized,with an APC of 0.39(P＞0.05).Conclusions The development of the CPC system in Tianjin significantly reduced key treatment times and improved the overall efficiency of AMI management.While population-level AMI mortality rates began to decline after 2015,the rate of improvement has slowed,indicating a continued need for optimizing the regional coordinated care system to further enhance patient outcomes.

Objective To evaluate platelet aggregation after 14 days of treatment with ticagrelor alone or aspirin plus ticagrelor in patients with stable coronary artery disease.Methods Patients with stable coronary artery disease receiving dual antiplatelet therapy with aspirin 100 mg/d plus clopidogrel 75 mg/d were randomly assigned to ticagrelor monotherapy group or ticagrelor plus aspirin group after washout of ticagrelor monotherapy.Platelet aggregation rate was measured after 7 days and 14 days.Results 57 patients(32 in Ticagrelor monotherapy group and 25 in Ticagrelor+Aspirin group)completed the follow-up.The mean age was(61.16±7.87)years.The platelet aggregation rates induced by arachidonic acid(AA),adenosine diphosphate(ADP),and collagen-induced were similar at baseline and randomization in both groups.After 14 days of treatment,the ADP-induced platelet aggregation rates in both groups were significantly lower than the baseline,but there was no statistical difference between the two groups[(21.50±7.86)％vs.(21.92±10.21)％,P=0.864].The ADP-induced platelet aggregation rates in both groups decreased compared to randomization,but the Ticagrelor monotherapy group was significantly higher than the Ticagrelor+Aspirin group[(48.22±24.01)％vs.(8.67±5.96)％,P＜0.001].In the monotherapy group,5 patients had a significant increase in the AA-induced platelet aggregation after the discontinuation of aspirin.After 14 days of continued Ticagrelor monotherapy,the AA-induced platelet aggregation rate decreased significantly again(＜30％).Conclusions Ticagrelor monotherapy exerts a strong inhibitory effect on ADP-induced platelet aggregation and a mild inhibitory effect on the AA-induced platelet aggregation.In addition to its strong inhibitory effect on ADP-induced platelet aggregation,the mild inhibitory effect of Ticagrelor on the AA-induced pathway may have some clinical significance for the early de-escalation of dual antiplatelet therapy to monotherapy in patients.

Objective To investigate neutralizing antibody levels in symptomatic and asymptomatic patients with coronavirus disease 2019 (COVID-19) at 6 and 10 months after disease onset. Methods Blood samples were collected at three different time points from 27 asymptomatic individuals and 69 symptomatic patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Virus-neutralizing antibody titers against SARS-CoV-2 in both groups were measured and statistically analyzed. Results The symptomatic and asymptomatic groups had higher neutralizing antibodies at 3 months and 1–2 months post polymerase chain reaction confirmation, respectively. However, neutralizing antibodies in both groups dropped significantly to lower levels at 6 months post-PCR confirmation. Conclusion Continued monitoring of symptomatic and asymptomatic individuals with COVID-19 is key to controlling the infection.

Objective Non-typhoid Salmonella is the main pathogen of foodborne diseases, and its prevalence has obvious seasonal characteristics. The detection of non-typhoid Salmonella usually increases when the temperature is high. However, there are significant differences in the duration, peak time and intensity of the epidemic of non-typhoid Salmonella in different years. Therefore, it is necessary to establish an evaluation method for the epidemic threshold and epidemic intensity of non-typhoid Salmonella to serve monitoring and early warning. Methods The data of non-typhoid Salmonella cases reported in the foodborne disease surveillance system of Jiangsu Province from January 2015 to December 2019 were collected. The moving epidemic method (MEM) was used to calculate the weekly epidemic threshold of non-typhoid Salmonella cases in Jiangsu Province using the surveillance data from 2015 to 2018, and to evaluate the epidemic intensity of non-typhoid Salmonella in 2019. Results The parameter δ was selected as 2.8, and the optimal MEM model was established. The weekly thresholds of non-typhoid Salmonella cases in Jiangsu Province were 3.53 at the beginning of the epidemic and 5.44 at the end of the epidemic, while the weekly thresholds were 12.58 for the epidemic week with moderate epidemic intensity, and 21.63 and 27.48 for the epidemic periods with high and very high epidemic intensity, respectively. The combined sensitivity and specificity of the model during the study period were 0.936 and 0.725, respectively. Conclusion Using MEM method to establish the epidemic threshold of non-typhoid Salmonella in Jiangsu Province has good sensitivity and acceptable specificity.

OBJECTIVE: This study optimizes three-dimensional (3D) culture conditions of HepG2 using response surface methodology (RSM) based on the VitroGel system to facilitate the cell model in vitro for liver tissues. METHOD: HepG2 cell was 3D cultured on the VitroGel system. Cell viability was detected using Cell Counting Kit-8 (CCK-8) assay of HepG2 lived cell numbers. The proliferation of HepG2 cell and clustering performance was measured via fluorescence staining test. Albumin concentration in the culture medium supernatant as an index of HepG2 cell biological function was measured with ELISA kit. Independent factor tests were conducted with three key factors: inoculated cell concentration, cultured time, and dilution degree of the hydrogel. The preliminary results of independent factor tests were used to determine the levels of factors for RSM. RESULT: The selected optimal culture conditions are as follows: concentration of inoculated cells was 4.44 × 10 ⁵/mL, culture time was 4.86 days, and hydrogel dilution degree was 1:2.23. The result shows that under optimal conditions, the predicted optical density (OD) value of cell viability was 3.10 and measured 2.978 with a relative error of 3.94%. CONCLUSION This study serves as a reference for the 3D HepG2 culture and constructs liver tissues in vitro. Additionally, it provides the foundation for repeated dose high-throughput toxicity studies and other scientific research work.
