In 2022, Hainan provincial government launched the project for the prevention and control of viral hepatitis with the goals of a hepatitis B screening rate of 90%, a diagnostic rate of 90%, and a treatment rate of 80% among people aged 18 years and above by the year 2025, and the main intervention measures include population-based prevention, case screening, antiviral therapy, and health management. As of December 31, 2024, a total of 6.875 million individuals in the general population had been screened for hepatitis B, with a screening rate of 95.6%. A total of 184 710 individuals with positive HBsAg were identified, among whom 156 772 were diagnosed through serological reexamination, resulting in a diagnostic rate of 84.9%. A total of 50 742 patients with chronic hepatitis B were identified, among whom 42 921 had hepatitis B-specific health records established for health management, with a file establishment rate of 84.6%. A total of 31 553 individuals received antiviral therapy, with a treatment rate of 62.2%. A total of 2.503 million individuals at a high risk of hepatitis C were screened, among whom 4 870 tested positive for HCV antibody and 3 858 underwent HCV RNA testing, resulting in a diagnostic rate of 79.2%, and 1 824 individuals with positive HCV RNA were identified, among whom 1 194 received antiviral therapy, with a treatment rate of 65.5%. In addition, 159 301 individuals with negative HBsAg and anti-HBs and an age of 20 — 40 years were inoculated with hepatitis B vaccine free of charge. Through the implementation of the project for the prevention and control of viral hepatitis, a large number of hepatitis patients have been identified, treated, and managed in the province within a short period of time, which significantly accelerates the efforts to eliminate the crisis of viral hepatitis.

Objective:This study analyzed the clinical characteristics and early mortality risk factors in patients with hyperleukocytic acute leukemia (HAL) to provide a basis for predicting early prognosis.Methods:Data were retrospectively collected from 211 patients with primary HAL who visited the Emergency Center of the Hematology Hospital, Chinese Academy of Medical Sciences, between July 1, 2019 and November 30, 2021. The value of each indicator in early risk stratification and prognosis was analyzed.Results:The early-death group exhibited higher WBC, peripheral blood immature cell proportions, prothrombin times (PT), fibrinogen degradation products (FDP), and D-dimer levels than the non-early death group ( P<0.05). Mortality in hyperleukocytic AML (20.5% ) was significantly higher than that in hyperleukocytic ALL (9.3% ) ( P<0.05). There were significant differences in age, creatinine, PT, fibrinogen (FIB) levels, WBC, lactic dehydrogenase (LDH), uric acid, blood potassium, blood calcium, and blood phosphorus levels between the two groups of patients ( P<0.05). A WBC threshold of 255.96×10?/L predicted early mortality with 65.6% sensitivity and 69.0% specificity, with higher WBC levels associated with a 5.164-fold increased mortality risk ( P<0.05). The age, WBC, LDH, urea, PT, FDP and D-dimer of patients at the time of consultation are risk factors affecting the survival of HAL ( P<0.05) . Conclusion:HAL is a life-threatening condition with a high early mortality. Age, WBC, LDH, urea, PT, FDP and D-dimer are risk factors for early death in HAL.

Objective:To study the survival and prognostic factors for the recurrent extracranial malignant germ cell tumors (MGCTs) in children, and to explore feasible salvage treatment.Methods:A retrospective study.Pediatric patients with recurrent extracranial MGCTs diagnosed in Shanghai Children′s Medical Center between January 2010 and January 2020 were retrospectively recruited.Comprehensive treatment regimens included surgery, chemotherapy and radiation.Kaplan-Meier survival analysis and Cox regression model were employed to analyze the survival and prognostic factors for children with recurrent extracranial MGCTs.Results:A total of 172 children with extracranial MGCTs were treated, including 21 (12.2%) recurrent cases.The median time of MGCT recurrence after the end of the first treatment was 11 months.Finally, 19 patients were recruited after excluding 2 non-eligible cases, including 10 boys and 9 girls with the age at recurrence of 26 (8-170) months.The follow-up time was 57 (13-122) months.Salvage chemotherapy, complete resection and radiotherapy were performed in 16, 14 and 4 patients, respectively.The 4-year overall survival (4yr-OS) rate was (82.5±9.2)%(19 cases). The 4yr-OS rate was significantly higher in patients managed with surgery but without adjuvant chemotherapy at the initial treatment (13 cases) than those managed with chemotherapy at the initial treatment (6 cases)[(92.3±7.4)% vs.(60.0%±21.9)%, P=0.002]. Univariant and Cox multivariant regression analyses showed that failure to achieve the normal range of alpha fetoprotein after 3 cycles of chemotherapy significantly influenced the survival of recurrent extracranial MGCTs. Conclusions:For patients with recurrent extracranial MGCTs, comprehensive treatment approaches like complete surgical resection, chemotherapy, and radiotherapy offer a favorable survival rate.Specifically, recurrent and re-treated patients who initially received surgery alone without adjuvant chemotherapy have a higher survival rate compared to those who received chemotherapy during the initial treatment.

Objective The occurrence of chickenpox in rapidly developing areas poses substantial seasonal risk to children.However,certain factors influencing local chickenpox outbreaks have not been studied.Here,we examined the relationship between spatial clustering,heterogeneity of chickenpox outbreaks,and socioeconomic factors in Southern China. Methods We assessed chickenpox outbreak data from Southern China between 2006 and 2021,comprising both relatively fast-growing parts and slower sub-regions,and provides a representative sample of many developing regions.We analyzed the spatial clustering attributes associated with chickenpox outbreaks using Moran's I and local indicators of spatial association and quantified their socioeconomic determinants using Geodetector q statistics. Results There were significant spatial heterogeneity in the risk of chickenpox outbreaks,with strong correlations between chickenpox risk and various factors,particularly demographics and living environment.Furthermore,interactive effects among specific are factors,such as population density and per capita residential building area,percentage of households with toilets,percentage of rental housing,exhibited q statistics of 0.28,0.25,and 0.24,respectively. Conclusion This study provides valuable insights into the spatial dynamics of chickenpox outbreaks in rapidly developing regions,revealing the socioeconomic factors affecting disease transmission.These implications extend the formulation of effective public health strategies and interventions to prevent and control chickenpox outbreaks in similar global contexts.

Head and neck tumor is a common malignant tumor with increasing incidence and mortality worldwide. Traditional diagnostic methods for head and neck tumor are limited by the lack of specific biomarkers and the limitation of invasive detection methods, as well as high time cost and a high rate of misdiagnosis. Therefore, research on head and neck tumor diagnosis based on new technologies is needed. Hyperspectral imaging (HSI) is a non-contact optical imaging technique that captures a series of images in multiple spectral bands to generate a hyperspectral image cube. HSI has shown its corresponding potential in the early diagnosis, tumor margin identification and clinical research of head and neck cancer.

Objective:To compare the safety of radial artery puncture in elderly patients aged 75 years and older who are undergoing neurointerventional procedures.Methods:A single-center retrospective study was conducted, involving 350 elderly patients aged 75 years and older who received neurointerventional treatment at Beijing Tiantan Hospital, Capital Medical University, from June to December 2022.The participants were divided into two groups based on the puncture site: femoral artery puncture and radial artery puncture.The safety indicators compared between the two groups included puncture failure, changes in puncture site, general puncture complications(such as subcutaneous bleeding, puncture site hematoma, and vasospasm), severe puncture complications(including distal limb ischemia and pseudoaneurysm), and lower limb venous thrombosis.Multivariate Logistic regression analysis was conducted to evaluate the impact of different puncture methods on the occurrence of complications.Results:Among the 350 patients, 280 underwent femoral artery puncture, while 70 underwent radial artery puncture.There were no statistically significant differences in baseline characteristics between the two groups(all P>0.05).The proportions of patients using antiplatelet drugs prior to surgery, puncture failure rates, rates of change in puncture sites, and the incidence of severe complications-including distal limb ischemia and pseudoaneurysm-were not significantly different between the two groups( χ2=2.051, 0.075, 0.588, 3.175; P=0.152, 0.784, 0.443, 0.075).In the femoral artery puncture group, 20.4%(57 cases)of patients experienced general puncture complications(including subcutaneous bleeding, puncture site hematoma, and vasospasm), whereas only 8.6%(6 cases)in the radial artery puncture group experienced such complications, revealing a statistically significant difference between the two groups( χ2=5.720, P=0.022).Multivariate Logistic regression analysis indicated that, compared to femoral artery puncture, radial artery puncture was associated with a reduced risk of all complications( OR=0.272, 95% CI: 0.139-0.532, P<0.001), general puncture complications( OR=0.375, 95% CI: 0.153-0.919, P=0.032)and lower limb venous thrombosis( OR=0.219, 95% CI: 0.050-0.954, P=0.043). Conclusions:In elderly patients aged 75 years and older who are undergoing neurointerventional procedures, radial artery puncture is associated with a reduced incidence of general puncture complications and lower limb venous thrombosis when compared to femoral artery puncture, indicating a superior safety profile.

To explore the epidemiological characteristics of public health emergency events (PHEE) of varicella in the Beijing-Tianjin-Hebei region and analyze its related influencing factors. Excel was used to organize the varicella data in the Beijing-Tianjin-Hebei region from 2006 to 2021, reported by the management information system of PHEE, to describe the epidemiological characteristics of varicella events. Spatial autocorrelation and spatial scanning methods were used to test and determine its spatial clusters. Geographic detectors were used to analyze the impact of socio-economic factors. From 2006 to 2021, there were 644 reported varicella events in the Beijing-Tianjin-Hebei region, with a total of 18 052 cases and an incidence rate of 2.78%. The number, duration and response time M ( Q1, Q3) of each reported event were 22 (15, 35) cases, 19 (7, 34) days and 7 (4, 17) days, respectively. Hebei Province had a shorter response time and duration of events compared to Beijing and Tianjin. The most reported varicella events were in 2006 and 2007, with 112 and 106 events, respectively. By 2014, the number of events had decreased yearly, and there was a small peak from 2017 to 2019 between 2014 and 2021. From 2006 to 2021, the PHEE of varicella showed a seasonal bimodal distribution from March to June and from October to January of the following year, with peaks in May and December. There was a total of 500 reported varicella events in primary schools, including 218 events in rural primary schools (34%), 142 events in county and town primary schools (22%) and 140 events in urban primary schools (22%). The distribution of varicella events showed a positive spatial autocorrelation and strong spatial clustering, with Moran′s I of 0.31. The Class 1 clustering area was centered in Kuancheng Manchu Autonomous County, Chengde City, with a radius of 207 km and included 58 districts ( LLR=3 550.23, RR=3.78). The most explanatory factor among socio-economic factors was the proportion of the population aged 0-24 years old ( q=0.22), and the interaction effect between each factor was stronger than the independent effect. Overall, there are differences in the level of handling varicella events across Beijing, Tianjin and Hebei. The main occurrence of varicella events is in primary schools, especially in rural areas. Varicella events exhibit spatial clustering. Population structure-related factors have a strong impact on the risk of the incidence of varicella events.
