Objective: To establish a prediction model for high-risk cardiovascular disease (CVD) among residents aged 35 to 75 years, so as to provide the basis for improving CVD prevention and control measures. Methods: Permanent residents aged 35 to 75 years were selected from Dongcheng District, Beijing Municipality using the stratified random sampling method from 2018 to 2023. Demographic information, lifestyle, waist circumference and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. Influencing factors for high-risk CVD among residents aged 35 to 75 years were identified using a multivariable logistic regression model, and a prediction model for high-risk CVD was established. The predictive effect was evaluated using the receiver operating characteristic (ROC) curve. Results: A total of 6 968 individuals were surveyed, including 2 821 males (40.49%) and 4 147 females (59.51%), and had a mean age of (59.92±9.33) years. There were 1 155 high-risk CVD population, with a detection rate of 16.58%. Multivariable logistic regression analysis showed that gender, age, smoking, central obesity, systolic blood pressure, fasting blood glucose, triglyceride and low-density lipoprotein cholesterol were influencing factors for high-risk CVD among residents aged 35 to 75 years (all P<0.05). The area under the ROC curve of the established prediction model was 0.849 (95%CI: 0.834-0.863), with a sensitivity of 0.693 and a specificity of 0.863, indicating good discrimination. Conclusion The model constructed by eight factors including demographic characteristics, lifestyle and blood biochemical indicators has good predictive value for high-risk CVD among residents aged 35 to 75 years.

ObjectiveTo explore the feasibility and rationality of applying relevant diagnostic and treatment programmes from textbooks as evidence in traditional Chinese medicine （TCM） diagnosis and treatment guidelines， using allergic rhinitis as an example. MethodsTextbooks published from October 1949 to December 2022， as well as TCM diagnosis and treatment guidelines published until December 2022 on allergic rhinitis were searched， and the contents of diagnosis and treatment related to allergic rhinitis were extracted. The similarities and differences between textbooks in different periods， between textbooks in different versions， and between textbooks and guidelines were compared and analyzed. ResultsA total of 12 national planning textbooks on TCM otolaryngology and 4 Chinese medicine diagnosis and treatment guidelines on allergic rhinitis from 1975 to 2021 were included. The evolution of diagnostic and treatment programmes was shown by the textbooks in different periods. Since 2003， syndrome of latent heat in lung channel has been added in the published textbook， and TCM featured therapies， such as nasal packing， intranasal spray were enriched， as well as the contents related to prevention and prognosis. The main syndromes included lung qi deficiency and cold， spleen qi deficiency， kidney yang deficiency， and latent heat in lung meridian. The most common recommended prescriptions were Wenfei Zhiliu Pill （温肺止流丹）， Yupingfeng Powder （玉屏风散） and Cangerzi Powder （苍耳子散）； Buzhong Yiqi Decoction （补中益气汤）， Shenling Baizhu Powder （参苓白术散）； Shenqi Pill （肾气丸） or Zhenwu Decoction （真武汤）； Xinyi Qingfei Decoction （辛夷清肺饮）. A comparison of different versions of textbooks showed that the classification of syndromes was consistent， while the formulas were slightly different. The comparison between different versions of the current textbooks and the guidelines showed that the recommended prescriptions of the textbooks had more Cangerzi Powder， Xiaoqinglong Decoction （小青龙汤）， Zhenwu Decoction， etc.， while TCM featured therapies such as nose blowing， smelling， nasal plugging， nasal washing were enriched， and information on formula modification， prevention and adjustment， prognosis were also added， which can supplement the corresponding evidence for the guidelines. ConclusionTextbooks could serve as a strong supplement for the evidence-based development of TCM clinical guidelines. However， there is still a need for further research on the quality assessment system of textbook evidence to improve the credibility of its applicability of the guidelines evidence.

This study used the Appraisal of Guidelines Research & Evaluation-Health Systems （AGREE-HS） to demonstratively compare 34 global coronavirus disease-2019 （COVID-19） health systems guidance documents （HSGs） and 6 World Health Organization （WHO） standard HSGs. The comparison involved topic， participants， methods， recommendations， and implementability， with the aim of exploring the characteristics of emergency HSGs. The results showed that the emergency HSGs had an overall average score of 49%， with topic having the highest score， recommendations having the second highest score， and participants having the lowest score. The standard HSGs had an overall average score of 79%， with high scores in all items. The emergency HSGs had lower scores in participants， methods， recommendations， and implementability than the standard HSGs （P<0.001）， while the COVID-19 emergency HSGs developed by the WHO had higher score in topic than the standard HSGs （P<0.05）. Compared with those released by countries， the COVID-19 emergency HSG developed by the WHO showed superiority in all items and overall scores （P=0.000 2）. This indicates that emergency HSGs， represented by the COVID-19 emergency HSG， place equal emphasis on topic and recommendations as standard HSGs but have low requirements in terms of expert participation， evidence support， and comprehensive consideration in the time- and resource-limited context. They have the characteristics of prominent topics， clear purposes， orientation to demand， keeping up with the latest evidence， flexible adjustment， and timeliness， emphasizing immediate implementation effects， weakening long-term effects， and focusing on comprehensive benefits. Additionally， developers， types， and report completeness are important influencing factors.

The scientific rigor and efficacy of methodologies employed in drafting emergency health systems guidance documents （HSGs） are paramount in guaranteeing the quality， reliability， and applicability of HSGs. According to the Appraisal of Guidelines for Research and Evaluation- Health Systems （AGREE-HS）， we demonstratively assessed both global coronavirus disease-2019 （COVID-19） emergency HSGs and World Health Organization （WHO） standard HSGs to uncover the core attributes of methods employed in the development of emergency HSGs. Our evaluation findings revealed that across the five assessment items of AGREE-HS， methods in the 34 emergency HSGs evaluated ranked third， trailing behind topic and recommendations. Notably， criterion 2 （the best available and most contextually relevant evidence is considered） received the highest score， whereas criterion 5 （evidence of cost and cost-effectiveness of the potential options is described） scored the lowest. Compared with the WHO standard HSGs， the COVID-19 emergency HSGs exhibited low scores in methods （P<0.05）， which was reflected in nine criteria （P<0.05）， especially in criteria 1 （systematic and transparent methods are used to identify and review the evidence） and 9 （systematic and transparent methods are used to agree upon the final recommendations）. Among the COVID-19 emergency HSGs， that developed by the WHO achieved higher scores in eight out of all nine criteria， excluding criterion 8 （P<0.05）. The clinically relevant emergency HSGs had higher scores in the criteria 3 （the evidence base is current） and 8 （the rationale behind the recommendations is clear） than other types of emergency HSGs. Collectively， the methodology for developing emergency HSGs， represented by the COVID-19 emergency HSG， underscores evidence orientation and integrates expert consensus. It is characterized by adaptable evidence synthesis strategies， streamlined evidence review protocols， and contextual relevance， all of which are influenced by external， internal， and implementation-specific factors.

Objective:To explore the relationship between gene mutation in the pre-C region of hepatitis B virus (HBV) and acute-on-chronic liver failure (ACLF) associated with hepatitis B.Methods:Fifty-eight patients with chronic hepatitis B (CHB) admitted to the General Hospital of Northern Theater Command of the Chinese People′s Liberation Army from May 2020 to May 2023 were selected as the CHB group, 51 patients with chronic hepatitis B liver cirrhosis (CHB-LC) were selected as the CHB-LC group, and 52 patients with hepatitis B-related acute-on-chronic liver failure were selected as the ACLF group. The clinicopathological data of the three groups were collected for retrospective analysis. Peripheral serum HBV DNA of the three groups was collected. The pre-C region genes of HBV in the three groups were amplified by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR), and then gene sequencing was performed. The variation at position 1896 of the pre-C region gene of HBV in the three groups was recorded. The general data, hepatitis B e antigen (HBeAg), HBV DNA quantification, triglycerides (TG), total cholesterol (TC), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), and gene mutation in the pre-C region of the three groups were observed and compared. Logistic regression analysis was performed on the related influencing factors of the onset of hepatitis B-related ACLF.Results:There were no statistically significant differences in gender, age, disease course, body mass index (BMI), TG, TC, and BUN among the three groups (all P>0.05), and there were statistically significant differences in HBeAg, HBV DNA quantification, ALT, and AST among the three groups (all P<0.05). The HBV DNA quantification, ALT, and AST in the ACLF group were higher than those in the CHB group and the CHB-LC group (all P<0.05). The mutation rate at position 1896 of the pre-C region gene of HBV in the ACLF group was higher than that in the CHB group and the CHB-LC group (all P<0.05); The results of logistic multivariate regression analysis showed that HBV DNA quantification, ALT, and gene mutation in the pre-C region were independent influencing factors for the onset of hepatitis B-related ACLF ( OR=1.042, 1.570, 1.413, P<0.05). Conclusions:The variation at position 1896 of the pre-C region gene of HBV is common in patients with HBV infection at different disease courses. The incidence of its variation shows a gradually increasing trend in CHB, CHB-LC, and ACLF. Elevated HBV DNA and ALT and gene mutation in the pre-C region of HBV are independent risk factors for the occurrence of hepatitis B-related ACLF. The progress of the disease in such patients requires clinical attention.

Objective: 18F-N-(2-(Diethylamino)ethyl)-5-(2-(2-(2-fluoroethoxy)ethoxy)ethoxy) picolinamide ( 18F-PFPN) is a novel positron emission tomography (PET) probe designed to specifically targets melanin. This study aimed to evaluate the diagnostic feasibility of 18F-PFPN in patients with ocular or orbital melanoma. Materials and Methods: Three patients with pathologically confirmed ocular or orbital melanoma (one male, two females; age 41–59 years) were retrospectively reviewed. Each patient underwent comprehensive 18F-PFPN and 18F-fluorodeoxyglucose ( 18F-FDG) PET scans. The maximum standardized uptake value (SUV max) of the lesion and the interference caused by background tissue were compared between 18F-PFPN and 18F-FDG PET imaging. In addition, the effect of intrinsic pigments in the uvea and retina on the interpretation of the results was examined. The contralateral non-tumorous eye of each patient served as a control. Results: All primary tumors (3/3) were detected using 18F-PFPN PET, while only two primary tumors were detected using 18F-FDG PET. Within each lesion, the SUV max of 18F-PFPN was 2.6 to 8.3 times higher than that of 18F-FDG. Regarding the quality of PET imaging, the physiological uptake of 18F-FDG PET in the brain and periocular tissues limited the imaging of tumors. However, 18F-PFPN PET minimized this interference. Notably, intrinsic pigments in the uvea and retina did not cause abnormal concentrations of 18F-PFPN, as no anomalous uptake of 18F-PFPN was detected in the healthy contralateral eyes. Conclusion Compared to 18F-FDG, 18F-PFPN demonstrated higher detection rates for ocular and orbital melanomas with minimal interference from surrounding tissues. This suggests that 18F-PFPN could be a promising clinical diagnostic tool for distinguishing malignant melanoma from benign pigmentation in ocular and orbital melanomas.
