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 explore the preoperative non-invasive prediction of early postoperative glioma recurrence using multi-modal conventional MRI radiomics.Methods A retrospective analysis of the clinical and MRI data of 83 glioma patients who met the inclusion criteria was conducted.The Kruskal-Wallis test was used to compare clinical factors between recurrent and non-recurrent groups.The automated segmentation of the entire tumor lesion for glioma patients was accomplished with VB-Net algorithm,a deep learning approach developed by United Imaging Healthcare;and the extraction of radiomics features from preoperative T1CE and T2WI images was carried out on URP platform.The optimal feature combination was determined using the maximum relevance and minimum redundancy and least absolute shrinkage and selection operator methods.Logistic regression and five-fold cross-validation were employed to analyze radiomics features and construct 4 prediction models,namely T2WI model,T1CE model,T2WI+T1CE model,and imaging-clinical fusion model.The diagnostic performances of these models were evaluated and compared using the area under the receiver operating characteristic curve(AUC)and the Delong test.In addition,the model sensitivity and specificity were calculated.Results Postoperatively,there were 40 recurrent cases and 43 non-recurrent cases.The clinical factors such as glioma grade showed statistical significance between two groups(P<0.05),while gender and age did not show significant statistical differences(P>0.05).For the single-sequence radiomics models,T1CE model(AUC:0.804)outperformed T2WI model(AUC:0.702).The multi-modal combined model exhibited a higher AUC than the single-sequence prediction models,with an AUC of 0.849,a sensitivity of 72.5%,and a specificity of 79.1%.The imaging-clinical fusion model whose predictive efficiency was close to that of multi-modal combined model(P=0.303)also performed well in forecasting postoperative glioma recurrence,with an AUC of 0.839,a sensitivity of 72.5%,and a specificity of 79.1%.Conclusion The multi-modal conventional MRI radiomics model can better predict early postoperative glioma recurrence.The imaging-clinical fusion model that includes glioma grade does not have the diagnostic performance superior to that of radiomics model.

Objective In this research,the documents in the field of plant tissue culture in the past decade were compared by the form of charts,and the possible reasons for these results were analyzed.The application of plant tissue culture in the field of medicinal plants was introduced in detail,and the shortcomings of its development were pointed out,in order to provide a reference for the future development of medicinal plant tissue culture.Methods The CNKI and WOS database were used as the data sources,the visual analysis software Bibliometrix,CiteSpace,and VOSviewer were used to analyze the study of plant tissue culture in the past decade.The publication,author,country,institution,citations,and keywords were visualized and discussed.And then,the results were retrieved by using medicinal plants as keywords,and focusing on medicinal plant tissue culture research.Results Within the scope of the study,902 publications in CNKI and 7658 publications in WOS were filtered out.The journals with the largest number of publications in medicinal plant tissue culture accounted for a relatively high proportion.The study reveals that the author of the largest number of Chinese publications,Wei Kunhua specializing in medicinal plants,whereas the most prolific author in English also dabbles in medicinal plants.The institutions with the most amount of publications mainly concerned on the establishment of tissue culture system in the medicinal plant tissue culture.In the issuing country,Chinese output occupies the first place.The hotspots of plant tissue culture research focus on the optimization of culture conditions,metabolomics and genomics in the research.Conclusion The domestic development in the field of plant tissue culture is lagging behind compared with that of foreign countries,and the cooperation and communication among various units should be strengthened;although domestic and foreign countries have paid attention to the medicinal plant tissue culture,most of research still remains in the basic application,and its development can be promoted by combining the research with multi-omics technology.

Objective:To evaluate the safety and efficacy of radiofrequency ablation（RFA）in the treatment of papillary thyroid microcarcinoma（PTMC）near and remote from the thyroid capsule.Methods:The clinical data，ultrasound images，ablation parameters and postoperative follow-up metrics were prospectively collected from 130 patients with pathologically confirmed PTMC in the Second Affiliated Hospital of Xi'an Jiaotong University who underwent RFA treatment between January 2023 and December 2024. According to whether the nodule margin was ≤ 2 mm from the thyroid capsule，the patients were divided into the subcapsular group（60 cases）and the remote from the capsule group（70 cases）. The clinical data，ablation parameters，complication rate，absorption of ablation lesions，tumor recurrence and metastasis were compared between the two groups.Results:The success rates of RFA in both groups were 100%. There was a statistically significant difference between the two groups at baseline in the location of nodules（ χ2=13.266， P=0.001）. After 12 months of routine follow-up，the incidence of complications was 5.00%（3/60）in the subcapsular group and 1.43%（1/70）in the remote from the capsule group，all complications recovered within 1 month，with no statistically significant difference（ P=0.407）. There were no significant changes in thyroid function［including free triiodothyronine（FT3），free thyroxine（FT4）and thyroid-stimulating hormone（TSH）］before and one month after RFA in the two groups（all P>0.05）. A statistically significant difference in the volume reduction rate（VRR）between the two groups was observed only when maximum diameter ≤ 5?mm at the 1st and 3rd months（all P<0.05）. For the remaining postoperative follow-up periods，there were no statistically significant differences in ablation zone volume or VRR between the two groups（all P>0.05）. At the final follow-up，for lesions with maximum diameter ≤ 5?mm，the tumor disappearance rate was 100% in both the subcapsular and remote from the capsule groups. For lesions with maximum diameter >5 mm，the rates were 78.4%（29/37）and 89.7%（26/29）in the respective groups，with no statistically significant difference between the two groups（ χ2 = 1.489， P =0.222）.There was no local tumor progression，lymph node metastasis or distant metastasis in either group. Conclusions:RFA is a safe and effective treatment for subcapsular PTMC，demonstrating comparable efficacy to that for PTMC located remote from the thyroid capsule.

Objective: To investigate the assocation of sedentary behavior among college students on psychological health issues, such as depressive, anxiety, and stress symptoms, and to analyze the moderating role of takeaway consumption behavior in the context, in order to provide a scientific basis for reducing emotional symptoms among college students. Methods: A stratified cluster sampling method was employed to conduct a questionnaire on 3 427 first year students of a higher education institution in Hefei of Anhui Province from May to June 2021. The study variables included demographic characteristics, sedentary time, takeaway consumption behavior, and emotional (symptoms depressive, anxiety, and stress symptoms). The Spearman correlation analysis was used to analyze the association between variables, and linear regression analysis was used to analyze the association between takeaway consumption behavior and depressive, anxiety and stress symptoms among college students with sedentary time. Results: Both sedentary time and takeaway consumption behavior were positively correlated with depressive, anxiety and stress symptoms among college students ( r =0.10, 0.10, 0.10; 0.10, 0.11, 0.11, all P <0.05). The results of linear regression analysis showed that the interaction term between takeaway consumption behavior and sedentary time was positively correlated with symptoms of depressive, anxiety, and stress symptoms among college students (depression: β =0.04, anxiety: β =0.04, stress: β =0.04, all P <0.05). The results of the simple slope test demonstrated that regardless of the level of takeaway consumption behavior, sedentary time was positively correlated with the depressive symptoms of college students; compared with low takeaway consumption behavior, high takeaway consumption behavior ( β=0.77, P <0.01) enhanced the association between sedentary time and depressive symptoms among college students. In addition, under the condition of high takeaway consumption behavior, sedentary time was positively correlated with the anxiety and stress symptoms of college students (anxiety: β =0.64; stress: β =0.71, both P <0.01); while under the condition of low takeaway consumption behavior, sedentary time was not related to the anxiety and stress symptoms of college students ( β =0.17, 0.22, both P >0.05). Conclusions Sedentary behavior is related to a the emotional symptoms of depressive, anxiety, and stress among college students. Takeaway consumption behavior may exacerbate this impact.

Objective:To investigate the influence of four preoperative CT image characteristics on the outcome of thoracoscopic surgery for chronic tuberculous empyema.Methods:This is a retrospective cohort study. Two hundred and eleven patients of tuberculous empyema who underwent video-assisted thoracic surgery(VATS) decortication at the First Department of Surgery , Wuhan Pulmonary Hospital from June 2020 to June 2023 were retrospectively analyzed. There were 162 male cases and 49 female cases, with an age ( M (IQR)) of 33 (27) years (range: 8 to 76 years). Patients were divided into two groups according to whether low-density lines, mass-patchy density, pleural fusion were observed, and the lesion size. Compare the clinical indicators of two groups of cases. Using the rapeutic efficacy as the dependent variable and four CT features as covariates, cases with cure or improve were included in Logistic regression analysis to calculate OR (95% CI) values. Results:Preoperative chest CT images showed that 127 cases (60.2%) had low-density lines, 102 cases (48.3%) had mass-patchy density, and 88 cases (47.7%) had pleural fusion. The lesions spanned 2 to 11 intercostal spaces, with a median of 7 intercostal spaces. The lesion size was divided into two groups according to <7 intercostal spaces and ≥7 intercostal spaces, with 101 cases (47.9%) and 110 cases (52.1%), respectively. In the intra-group comparison, there were no difference in age, lesion location and pulmonary tuberculosis. In the comparison of gender, except that the proportion of female patients in the group with lesion size <7 intercostal spaces ( χ2=6.064, P=0.010) was higher than ≥7 intercostal spaces, there were no significant difference between other groups. In low-density lines group, there was no difference in the incidence of anemia and hypoproteinemia between the two groups. Compared with the non low-density line group, patients with low-density line group exhibited fewer cases of abnormal elevation in ESR and CRP was lower(all P<0.01), the period of preoperative treatment ( U=7 281.00, P<0.01) was longer than the non low-density line group, while the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration, and therapeutic efficacy were all better than the non low-density line group(all P<0.05). In the comparison between the mass-patchy density group, there were fewer cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP in the without mass-patchy density group(all P<0.05), and the period of preoperative treatmentwas shorter ( U=4 581.50, P=0.026), and the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration and therapeutic effect were better too(all P<0.05). In the grouping comparison of pleural fusion, there were no difference in cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP, and the period of preoperative treatment between the two groups; the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration, and therapeutic efficacy of the group without pleural fusion were better than the group with pleural fusion(all P<0.05). The group with <7 intercostal spaces had fewer cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP (all P<0.05), the period of preoperative treatment was longer ( U=4 295.00, P=0.004), the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours,postoperative drainage duration, lung re-expansion duration and complications were less (all P<0.05), the therapeutic efficacy was better than the group with ≥7 intercostal spaces ( χ2=27.912, P<0.01). The Logistic regression analysis of cured and improved cases showed that mass-patchy density and lesion size were independent risk factors affecting the therapeutic efficacy (all P<0.05). Conclusions:For patients with CT images showing mass-patchy density, pleural fusion, and a large lesion size, the difficulty and risk of surgery may be relatively high.The preoperative CT images can provide objective reference for clinical preoperative evaluation.
