Objective To investigate the incidence trend of infectious diseases among kindergarten children in Yangpu District, Shanghai, and to provide scientific reference for prevention and control strategies of infectious diseases among key populations. Methods Descriptive epidemiology method and Joinpoint regression analysis model were used to analyze the surveillance data of infectious diseases among kindergarten children. Results The average annual reported incidence of infectious diseases among kindergarten children in Yangpu District was 3,344.08/100,000, showing a downward trend (AAPC=-5.51, 95%CI: -13.02~2.63). Intestinal (65.49%) and respiratory (34.48%) infectious diseases were the main cases. There were 7,378 cases of hand, foot and mouth disease (62.95%), 1,885 cases of influenza (16.08%), 1,378 cases of varicella (11.76%), and 392 cases of mumps (3.34%), accounting for 94.14% of all reported cases. Hand, foot and mouth disease (AAPC=-17.68%, 95%CI: -27.52~-6.51), mumps (AAPC=-9.33, 95%CI: -14.86~-3.45) and varicella (AAPC=-7.32, 95%CI: -17.35~3.93) showed an overall decreasing trend, while influenza (AAPC=32.19, 95%CI: 12.49-55.34) was on the rise. The incidence of the disease showed double peak distribution, and the high incidence months were from May to July and from September to December. The male to female ratio was 1.39:1. Conclusion The incidence of infectious diseases among kindergarten children in Yangpu District shows a downward trend. It is necessary to continue to increase the coverage rate of Enterovirus 71(EV71), influenza, chickenpox and MMR combined live attenuated vaccine, strengthen monitoring and early warning, actively carry out health guidance, and effectively control the occurrence of common infectious diseases in kindergarten children.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Objective To evaluate the ability of longitudinal changes in urinary extracellular domain of neurotrophin receptor p75(p75ECD)to serve as a prognostic biomarker of severity,progression and survival time in patients with amyotrophic lateral sclerosis(ALS).Methods Forty patients with ALS attended follow-up appointments at 3-to 6-month interval,and 51 healthy control(HC)volunteers were recruited.The concentrations of urinary p75ECD were tested by a sandwich ELISA.The ALSFRS-r was used to quantify the severity of ALS.The change rate of urinary p75ECD(Δp75ECD)was calculated as the average monthly change during the period between the first and the last sampling.Results The concentration of urinary p75ECD was higher at the last follow-up than at baseline(P=0.002 3).Spearman analysis showed that there was a negative correlation between urinary p75ECD and ALSFRS-r score(r=-0.35,P=0.001 3);the course of ALS in the fast-changing Δp75ECD group was shorter than that in the slow-changing group(P=0.015 8);the Δp75ECD and course of ALS showed a negative correlation(r=-0.39,P=0.014),and the Δp75ECD in the fast-progression ALS group was significantly higher than in the slow-progression group(P=0.001 6).There was a positive correlation between Δp75ECD and progression in ALS patients(r=0.34,P=0.005).Kaplan-Meier survival analysis showed a longer median survival time in those with slow-changing Δp75ECD(P=0.03).Conclusion The change rate of urinary p75ECD has shown great potential as a biomarker for the prognosis of the severity,progression and survival time of ALS.

Objective:To investigate the application of contrast-enhanced ultrasound (CEUS) in the diagnosis of hepatocellular carcinoma (HCC) and evaluate the therapeutic efficacy of radiofrequency ablation.Methods:A case-control study was conducted among high-risk HCC patients who underwent puncture biopsies at Lishui Central Hospital from January 2019 to January 2023. A total of 118 confirmed HCC patients were selected as the case group, and 118 patients with hepatitis B cirrhosis were selected as the control group, following a 1:1 matching principle. All patients underwent a CEUS examination, and the therapeutic efficacy of CEUS in detecting HCC was analyzed. The case group underwent radiofrequency ablation for 1 month. The case group underwent 1 month of radiofrequency ablation treatment, and the application value of CEUS in assessing the efficacy of radiofrequency ablation for HCC was evaluated based on the results of Gd-EOB-DTPA-enhanced magnetic resonance imaging.Results:The results of the CEUS examination were compared with the pathological diagnosis results. In the case group, 6 cases were misdiagnosed, while in the control group, 8 cases were missed. The diagnostic accuracy of CEUS was 94.07%, and the Cohen's Kappa value for CEUS was 0.88, indicating a good consistency between CEUS and pathological diagnosis results. After radiofrequency ablation, the alpha-fetoprotein levels in the case group decreased significantly from [(141.27 ± 34.90) μg/L] before the procedure to [(59.78 ± 14.55) μg/L] after the procedure ( t = 24.32, P < 0.001). However, the longest diameter of the lesions increased from [(17.44 ± 4.17) mm] before the procedure to [(28.47 ± 5.41) mm] after the procedure ( t = -16.46, P < 0.001). There was no statistically significant difference in the longest diameter of the tumors assessed by CEUS postoperatively compared to the Gd-EOB-DTPA-enhanced MRI results ( P > 0.05). When comparing the efficacy of radiofrequency ablation assessed by CEUS to the results from Gd-EOB-DTPA-enhanced MRI, there were 8 true positive cases, 107 true negative cases, and 3 cases that were misdiagnosed. The accuracy of CEUS in assessing the efficacy of radiofrequency ablation for HCC was 97.46%, with a Cohen's Kappa value of 0.83. Conclusions:CEUS demonstrates a high accuracy in the diagnosis of HCC and can serve as an effective method for evaluating the efficacy of radiofrequency ablation. It shows good consistency with pathological diagnoses and Gd-EOB-DTPA-enhanced MRI results, indicating a high clinical application value.

Objective:New HIV infections serve as a crucial indicator for assessing the dynamic changes in the HIV epidemic. This study aims to estimate the number of new HIV infections in Dehong Dai and Jingpo Autonomous Prefecture of Yunnan Province (Dehong), using a back-calculation method that integrates diagnosis delay approaches and Bayesian theory. Additionally, it compares the differences between these two estimation methods.Methods:Data were obtained from the Chinese Information System for Disease Control and Prevention. Based on CD4 + T lymphocytes (CD4) counts depletion model, the first CD4 count prior to antiretroviral therapy of HIV-infected individuals diagnosed in Dehong from 2010 to 2023 was utilized to retroactively determine the infection date of HIV-infected individuals and ascertain the annual number of new HIV infections who had been diagnosed. Subsequently, the diagnosis delay distribution method and Bayesian theory were leveraged to assess the diagnosis probability of newly infected individuals, thereby projecting the number of new HIV infections in the region over the specified period. Results:During 2010-2023, a total of 5 693 individuals aged 15 and above, excluding mother-to-child transmission, were diagnosed with HIV in Dehong. After excluding 364 cases due to missing CD4 count results or abnormal first CD4 counts (≥2 000 cells/μl), 5 329 HIV-infected individuals were included in the final analysis. Through CD4 counts back-calculation from 2010 to 2023, the annual number of new infections diagnosed was 479, 427, 337, 305, 256, 219, 194, 193, 131, 166, 120, 71, 42 and 47. When using the diagnosis delay distribution method and life table analysis, the cumulative diagnosis probability rose from 0.301 within one year to 0.913 within 14 years, leading to a reduction in the number of estimated new infections from 577 in 2010 to 168 in 2023, with a total estimate of 4 412 (95% CI:4 350-4 480). Alternatively, based on Bayesian theory, the diagnosis probability increased from 0.413 within one year to 0.946 within 14 years, leading to a reduction in the number of estimated new infections from 557 in 2010 to 122 in 2023, with a total of 3 814 (95% CI: 3 787-3 837). Conclusions:Both methods yielded consistent results in estimating new HIV infections in Dehong from 2010 to 2023. Given the region's ongoing expansion of HIV testing, the estimates derived from Bayesian theory may more accurately reflect the actual situation. These findings provide a reference basis for formulating and optimizing HIV/AIDS prevention and control strategies in Dehong, facilitating progress toward the goal of eliminating AIDS by 2030 in the region.

ObjectiveTo analyze the incidence rate and mortality of acute myocardial infarction (AMI) and their changing trends among the registered residents in Xiaoshan District, Hangzhou City from 2017 to 2023, so as to provide references for formulating policies related to AMI prevention. MethodsThe morbidity and mortality data of AMI among the registered residents in Xiaoshan District from 2017 to 2023 were collected through the Hangzhou Chronic Disease and Death Cause Monitoring System. Software such as Excel 2019, SPSS 25.0 and Joinpoint 4.9.1.0 were used to calculate the incidence rate, mortality, and average annual percentage change (AAPC) of AMI. ResultsFrom 2017 to 2023, the average annual crude incidence rate, age-standardized incidence rate using China standard population (ASIRC), and the age-standardized incidence rate using World standard population (ASIRW) of AMI in Xiaoshan District were 48.25/100 000, 29.14/100 000, and 21.64/100 000, respectively, and, from which the AAPCs were 5.495%, 6.010%, and 6.533%, respectively, all showing an upward trend. The average annual crude mortality rate, the age-standardized mortality rate using China standard population (ASMRC), and the age-standardized mortality rate using World standard population (ASMRW) were 11.76/100 000, 6.52/100 000, and 4.71/100 000, respectively, from which the AAPCs were -9.669%, -10.433% and -9.615%, respectively, all showing a downward trend. The average annual crude incidence rate of AMI was higher in males (65.87/100 000) than that in females (31.31/100 000). Moreover, the average annual crude mortality rate of AMI was higher in males (14.08/100 000) than that in females (9.52/100 000), and the difference was statistically significant (all P<0.001) .After age grouping, the crude incidence rate of AMI among the residents aged 35-, 45-, 55-, and 65- years in Xiaoshan District from 2017 to 2023 showed an upward trend over time, with AAPCs of 16.993%, 17.149%, 8.523%, and 5.002%, respectively. While the crude mortality rate in residents aged 35-, 75-, and 85-102 years showed an decreasing trend over time, with AAPCs of -23.977%, -15.467%, and -17.415%, respectively, but there was no statistically significant difference in the trends in incidence rate and mortality of other age groups (all P>0.05). ConclusionThe situation of AMI prevention and control among the registered residents in Xiaoshan District is not optimistic, and targeted measures should be strengthened for the male residents aged ≥35 years old.
