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: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:To investigate the clinical significance of tumor budding as an indicator of postoperative distant organ metastasis after radical gastrectomy in elderly patients diagnosed with gastric cancer.Methods:The clinical and pathological data of 124 elderly patients who experienced metastasis after undergoing radical gastrectomy were retrospectively analyzed.The analysis was conducted from March 2015 to June 2022, focusing on the clinicopathological factors that influenced the occurrence of postoperative distant metastasis in these patients.Tumor budding in gastric cancer tissues was assessed using hematoxylin-eosin staining, and its clinical significance was analyzed.Results:The tumor budding grade of gastric cancer tissues showed a significant correlation with vascular invasion( χ2=6.731, P=0.009), the number of lymph node metastases( rs=0.481, P<0.001), and the time of distant metastasis( rs=-0.450, P<0.001).In the univariate analysis, factors such as tumor budding grade, tumor size, vascular invasion, postoperative chemotherapy, cancerous nodule, preoperative serum carbohydrate antigen 125, and the number of lymph node metastases were found to influence distant metastasis-free survival after radical gastrectomy in elderly patients(all P<0.05).The multifactorial analysis also indicated that tumour outgrowth grade was an important independent prognostic factor for postoperative distant metastasis in elderly gastric cancer patients( HR=3.731, P<0.001). Conclusions:The findings of this study indicate that tumor budding may serve as a potential marker for predicting distant organ metastasis in elderly patients who have undergone radical gastrectomy.This discovery holds significant clinical implications.

Objective: To examine the developmental trajectory of fine motor ability in schoolage children with attention deficit hyperactivity disorder (ADHD) for two years, so as to provide scientific evidence to promote motor development in ADHD children. Methods: From April to June 2019, 31 children aged 6-8 years old were selected from a public elementary school. They were diagnosed with ADHD by two psychiatric professionals according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. Additionally, 31 typical developmental children, matched for age, sex and IQ with the ADHD group, were recruited as the control group. Fine motor ability was assessed with tasks of hand manual dexterity in Movement Assessment Battery for Children-2 (MACB-2), and a followup assessment was conducted from April to June 2021. The development changes of fine motor ability between two groups of children were compared by using t test and repeated measures analysis of variance. Results: Between baseline and followup periods after two years, the total score of hand fine motor in the ADHD group did not show significant improvement (7.4±3.0, 8.0±3.4; t=-1.05, P>0.05), while there was a small effect size improvement in typically developing control group (9.5±2.1, 10.5±2.4; t=-2.12, effect size=0.38, P<0.05). Followup after two years, coin/peg throwing scores with dominant hand improved between ADHD group and control group (7.0±3.3, 9.5±3.2; 8.4±2.8, 11.6±1.6) (t=-3.74, -6.33, P<0.01; effect size=0.67, 1.14), with a smaller improvement in the ADHD group. The score for threading beads/threads decreased in between ADHD group and control group (7.9±2.4, 5.8±3.1; 9.2±1.1, 8.2±1.9) (t=3.89, 2.78, P<0.01; effect size=0.70, 0.50), with a greater decrease in the ADHD group. Conclusions The development speed of fine motor ability in children with ADHD aged 6-8 is slow and continues to lag behind normal developmental children. Fine motor development in children with ADHD should be closely monitored, and targeted interventions should be implemented when necessary.

Objective: Idiopathic intracranial hypertension (IIH) is a condition of unknown etiology associated with venous sinus stenosis. This study aimed to develop a magnetic resonance venography (MRV)-based radiomics model for predicting a high trans-stenotic pressure gradient (TPG) in IIH patients diagnosed with venous sinus stenosis. Materials and Methods: This retrospective study included 105 IIH patients (median age [interquartile range], 35 years [27– 42 years]; female:male, 82:23) who underwent MRV and catheter venography complemented by venous manometry. Contrast enhanced-MRV was conducted under 1.5 Tesla system, and the images were reconstructed using a standard algorithm. Shape features were derived from MRV images via the PyRadiomics package and selected by utilizing the least absolute shrinkage and selection operator (LASSO) method. A radiomics score for predicting high TPG (≥ 8 mmHg) in IIH patients was formulated using multivariable logistic regression; its discrimination performance was assessed using the area under the receiver operating characteristic curve (AUROC). A nomogram was constructed by incorporating the radiomics scores and clinical features. Results: Data from 105 patients were randomly divided into two distinct datasets for model training (n = 73; 50 and 23 with and without high TPG, respectively) and testing (n = 32; 22 and 10 with and without high TPG, respectively). Three informative shape features were identified in the training datasets: least axis length, sphericity, and maximum three-dimensional diameter.The radiomics score for predicting high TPG in IIH patients demonstrated an AUROC of 0.906 (95% confidence interval, 0.836– 0.976) in the training dataset and 0.877 (95% confidence interval, 0.755–0.999) in the test dataset. The nomogram showed good calibration. Conclusion Our study presents the feasibility of a novel model for predicting high TPG in IIH patients using radiomics analysis of noninvasive MRV-based shape features. This information may aid clinicians in identifying patients who may benefit from stenting.

Objective To explore the diagnostic value of Young's modulus obtained by real-time shear wave elastography (SWE) for liver fibrosis in autoimmune hepatitis (AIH) patients. Methods A total of 75 AIH patients in the First Affiliated Hospital of Zhengzhou University from January 2013 to April 2022 were retrospectively enrolled. Scheuer scoring system was used to evaluate degrees of liver fibrosis (S0-S4). By using pathological examination of liver tissues as the golden standard, the receiver operating characteristic curve (ROC) was plotted and the area under the curve (AUC) was used to evaluate the diagnostic value of SWE for the significant fibrosis (≥S2), advanced liver fibrosis (≥S3), and liver cirrhosis (S4), respectively. Independent sample t test was used for comparison of continuous data with normal distribution between the two groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and Bonferroni method was used for further comparison between two groups. The Spearman correlation coefficient was used for correlation analysis. The logistic regression analysis was used to predict the impact factors in diagnosis accuracy. Results The Young's modulus measured by SWE was statistically significant different among various fibrosis groups ( H =35.186, P < 0.001) although there was no statistical significance in patients' age and platelet, alanine aminotransferase, aspartate aminotransferase, total bilirubin, alkaline phosphatase, and glutamyl transpeptidase levels (all P > 0.05). The Young's modulus measurement was positively correlated with liver fibrosis ( r =0.675, P < 0.05). The AUCs of SWE in the diagnosis of≥S2, ≥S3, and S4 were 0.839, 0.820 and 0.898, respectively and the corresponding optimum cut-off values were 9.2, 10.9, and 14.4 kPa, respectively. The overall concordance rate of the liver Young' s modulus measurements vs . fibrosis stages was 57.33%. Moreover, the alkaline phosphatase level was an independent predictor for diagnostic accuracy of SWE for stage 0-1 fibrosis ( OR =1.009, 95% CI : 1.001-1.018, P =0.029). Conclusion The SWE possessed a diagnosis value for the significant fibrosis (≥S2), advanced liver fibrosis (≥S3) and liver cirrhosis (S4), although there was a low overall concordance rate in the liver Young's modulus measurements obtained using SWE vs. fibrosis stages.

Objective:To explore application of mixed teaching platform in the clinical practice teaching of the laboratory medicine in Children's hospitals.Methods:We constructed a mixed online and offline teaching platform based on the Laboratory Quality Management System (LQMS) in the Children's Hospital of Chongqing Medical University. The undergraduates from Batch 2016 ( n=15) and Batch 2018 ( n=12) of College of Laboratory Medicine of Chongqing Medical University were taken as control group and experimental group respectively. Traditional teaching method was adopted by the control group, and the mixed teaching method was adopted by the experimental group. The results of two groups' clinical practice assessment, rate of outstanding students (total score ≥ 90) and rate of satisfaction (score ≥ 90) were compared to evaluate the teaching effect. SPSS 17.0 was used to conduct t-test and Chi-square test. Results:The database of teaching platform includes 68 teaching cases, 198 pieces of courseware, 305 clinical cases and 3 036 atlases. The test bank has accumulated 4 657 tests, covering clinical laboratory, immunology, biochemistry, microbiology and blood transfusion. The results of students in experimental group were significantly better than those of the control group [the score of clinical practice assessment: (85.90±5.04) vs. (78.90±6.75)( P<0.05); rate of outstanding students: 33.3% (4/12) vs. 6.7% (1/15), P>0.05; rate of satisfaction: 86.7% (13/15) vs. 100.0% (12/12) ( P>0.05). Conclusion:The mixed online and offline teaching platform based on the LQMS is highly recognized by students and can significantly improve the effect of clinical practice teaching, which can provide typical medical case teaching at any time and make up for limited case type in children's hospital.

Objective:To understand the epidemiological characteristics of public health emergency events (PHEE) of varicella in China from 2006 to 2021 and related response performances.Methods:The data of varicella PHEE in 31 provinces of China from 2006 to 2021 were collected through the Public Health Emergency Management Information System, Microsoft Excel 2019 software and SPSS 26.0 statistical software were used to conduct descriptive epidemiological, statistical analysis on the time, area, location distribution, scale and epidemic management.Results:A total of 11 443 PHEE involving 341 048 related cases were reported from 2006 to 2021, with an annual attack rate of 1.78%-3.80% and a total attack rate of 2.33% (341 048/14 624 042). The number of PHEE and related cases of varicella decreased from 1 107 (35 349) in 2007 to 262 (6 884) in 2012 ( Z=-2.40, P<0.001), then increased year by year to 1 318 (42 649) in 2019 ( Z=2.58, P<0.001), with a significant decline since 2020. The varicella PHEE in China presents the seasonal characteristics,the peak is from April to June and from October to December, respectively. The sub-peak of varicella PHEE in eastern China generally appears 1-2 months earlier than in central and western China. Varicella PHEE reports are mainly distributed in eastern China, the attack rate is relatively high in western China, school-reported varicella PHEE was 88.26% of the total reports (10 099/11 443). The epidemic scale of varrcella PHEE typically range from 10 to 29 cases per year among the given outbreaks. The M ( Q1, Q3) of average number of cases, average duration, and average reporting interval of PHEE were 23 (16,35), 20 (14, 26) days, and 9 (5,19) days, respectively, and the reporting interval was positively correlated with the duration ( r=0.854, P<0.001). Conclusions:The varicella PHEE in China from 2006 to 2021 has not been effectively controlled. Schools are the key places to prevent and control varicella PHEE. Improving the sensitivity of varicella PHEE monitoring, strengthening the timely disposal of varicella epidemic, and promoting varicella vaccination are effective measures to prevent and control varicella PHEE.
