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.

Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

ObjectiveA multiplex amplification system was constructed based on the capillary electrophoresis platform for simultaneous detection of saliva, semen, and vaginal secretions using tissue-specific RNA markers. The aim of this study is to identify the tissue origin of suspicious body fluid stains found at crime scenes and determine whether the body fluid stains at the crime scene are one or several types among saliva, semen, and vaginal secretions. MethodsThirty saliva samples, forty semen samples, and forty vaginal secretion samples (half from 2015 and half from 2024) were collected from healthy adult volunteers. Through primer designing, system formulation, and PCR condition optimization, a multiplex fluorescent amplification system was constructed. The specificity, sensitivity, and detection ability for mixed samples of this system were investigated, and it was tested using real crime scene materials. In the primer design stage, to reduce the requirements for RNA template quality, the amplification products were set within 80-300 bp. In the system formulation stage, dominant and subordinate primers were mainly considered. By reducing the concentration of dominant primers and increasing that of subordinate primers, a capillary electrophoresis spectrum with an appropriate peak height ratio was finally obtained. Additionally, gradient experiments were designed to adjust the concentrations of PCR reagents and PCR amplification conditions, and multiple versions of DNA amplification enzymes were optimized to achieve the best experimental results. ResultsThrough statistical analysis, there was no significant difference in the capillary electrophoresis of the 3 types of body fluid samples from the two years (2015 and 2024), demonstrating that the sample preservation method in this study can preserve samples for a relatively long time. The composite amplification system constructed in this study exhibited high specificity for all 3 types of body fluid, with no cross-reactions between the markers of each type of body fluid. The minimum detection thresholds for the 3 types of body fluid reached 0.002 9, 0.001 5, and 0.42 mg/L, respectively. This system also had a high degree of discrimination for mixed samples, especially for semen-saliva mixtures, where each body fluid marker could still be successfully detected when the concentration ratio of semen to saliva was 100:1. Meanwhile, in the two actual cases presented in this article, the application of this composite amplification system performed outstandingly. ConclusionThe composite amplification detection system constructed in this study can achieve the correct screening of saliva, semen, and vaginal secretions, overcoming the problems such as low specificity and sensitivity of marker tests and unbalanced RFU values of each marker in previous studies. The specificity and sensitivity meet the practical work requirements, and the operation is simple. It provides an analytical and identification method for body fluid stains in actual case and is applicable to the identification of the tissue origin of biological evidence at crime scenes involving sexual assault, indecent assault, and other criminal acts. In the future, more types of body fluid markers will be screened to expand the types of body fluids detected by the system, and body fluid-specific cSNP and cInDel genetic markers will be introduced to infer the sources (individuals and types) of mixed and complex stains more accurately.

To introduce and analyze guideline terminology related to clinical question formulation, evidence retrieval and appraisal, and recommendation development. A systematic search was conducted in guideline development manuals and relevant methodological literature, covering publications up to October 25, 2024. Terminology related to the three aforementioned stages of related to guideline development was extracted from the included literature, standardized, and refined through consensus meetings to finalize a comprehensive terminology list and definitions. A total of 30 guideline development manuals and 15 methodological articles were included, and 23 core terms were identified. It is recommended to develop a standardized and scientifically sound guideline terminology system with unified naming, clear definitions, and alignment with the linguistic environment and usage habits in China. At the same time, it is essential to strengthen terminology training for both guideline developers and users based on this system, in order to deepen their correct understanding and proper application of guideline terminology.

ObjectiveBased on the quality evaluation experience of "it is better to have a fragrant and strong aroma" summarized by materia medica of past dynasties, the chemical components of Sojae Semen Nigrum(SSN) and Sojae Semen Praeparatum(SSP) were systematically compared and analyzed, and the main fermentation products in different fermentation time were quantitatively analyzed, so as to clarify the transformation law of internal components in the processing process and provide scientific basis for the modern quality control of SSP. MethodUltra performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used for the structural identification of the chemical constituents of SSN and SSP, and with the aid of Progenesis QI v2.3 software, the negative ion mode was employed for principal component analysis(PCA) pattern recognition, and the data were analyzed with the aid of orthogonal partial least squares-discriminant analysis(OPLS-DA) for two-dimensional data to obtain S-plot, and components with |P|>0.1 were selected as the differential constituents. The contents of isoflavonoids in SSP during fermentation was determined by UPLC, and the samples were taken every 8 h in the pre-fermentation period and every 2 d in the post-fermentation period, and the dynamic changes of isoflavonoid contents in different fermentation stages were analyzed. The contents of amino acids and nucleosides in SSP and SSN from different fermentation stages were quantitatively analyzed by phenyl isothiocyanate(PITC) pre-column derivatization and high performance liquid chromatography(HPLC) gradient elution, and the contribution of flavor substances to the "delicious" taste of SSP was discussed by taste intensity value(TAV). ResultA total of 19 kinds of differential components were screened out, mainly soybean saponins and isoflavones, and their contents decreased significantly or even disappeared after fermentation. In the pre-fermentation process of SSP, glycoside bond hydrolysis mainly occurred, and isoflavone glycosides in SSN were degraded and converted into the corresponding aglycones, the content of flavor substances such as amino acids increased gradually. In the post-fermentation process, protein degradation mainly occurred, after 8 d of post-fermentation, the content of isoflavones was basically stable, while the total content of amino acids increased by 8-40 times on average. Different amino acids form the special flavor of SSP, such as the TAV of glutamate is always ahead of other flavor substances, and sweet substances such as alanine and valine have made relatively great contributions to SSP. ConclusionBased on the law of constituent transformation, combined with the traditional evaluation index of "fragrant and strong", it is difficult to control the fermentation degree of SSP by the existing standards in the 2020 edition of Chinese Pharmacopoeia. It is suggested that description of the characteristics of SSP be refined and changed to "fragrant, delicious and slightly sweet", and at the same time, the post-fermentation index compounds such as glutamic acid, alanine and valine should be added as the quality control indicators of SSP, so as to standardize the production process and improve the quality of SSP.

ObjectiveTo investigate the mechanism of Atractylodis Macrocephalae Rhizoma(AMR) in the treatment of slow-transmission constipation(STC) by observing the effects of AMR on short-chain fatty acids and intestinal barries in STC mice. MethodForty-eight male KM mice were randomly divided into blank group, model group, AMR low-, medium-, high-dose groups(2.5, 5, 10 g·kg-1) and mosapride group(2.5 mg·kg-1). Except for the blank group, all groups were gavaged with loperamide suspension(5 mg·kg-1) twice daily for 14 d to construct the STC mouse model. At the same time, each drug administration group was given the corresponding drug by gavage for consecutive 14 d, the blank and model groups were gavaged with equal volume of distilled water. The effects of the treatment of AMR on body mass, defecation frequency, fecal water content and intestinal propulsion rate of mice were observed, the pathological changes of mouse colon were observed by hematoxylin-eosin(HE) staining and periodic acid-Schiff(PAS) staining, the levels of gastrin(GAS) and motilin(MTL) in serum were detected by enzyme-linked immunosorbent assay(ELISA), gas chromatography-mass spectrometry(GC-MS) was used to detect the contents of short-chain fatty acids(SCFAs) in mouse feces, real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to determine the mRNA and protein expression levels of zonula occludens-1(ZO-1), Occludin, and Claudin-1 in the colon of mice. ResultCompared with the blank group, the body mass, defecation frequency, fecal water content and intestinal propulsion rate of mice in the model group were significantly decreased(P<0.05, P<0.01), the arrangement of colonic tissues was disordered, and the number of goblet cells was reduced, the levels of GAS and MTL in serum were significantly decreased(P<0.01), and the levels of SCFAs in the feces were on a decreasing trend, with the contents of acetic acid, propionic acid, butyric acid, isobutyric acid and valeric acid were significantly decreased(P<0.05, P<0.01), the mRNA and protein expression levels of ZO-1, Occludin and Claudin-1 in the colonic tissues were significantly decreased(P<0.01). The above results suggested that STC mouse model was successfully constructed. Compared with the model group, the body mass, defecation frequency, fecal water content and intestinal propulsion rate of mice in AMP administration groups all increased significantly(P<0.05, P<0.01), the mucosal layer of the colonic tissues was structurally intact without obvious damage, and the number of goblet cells increased, serum levels of GAS and MTL were significantly increased(P<0.01), the contents of SCFAs in the feces were all on a rising trend, with the contents of acetic, propionic, butyric and isobutyric acids rising significantly(P<0.05, P<0.01), the mRNA and protein expression levels of ZO-1, Occludin and Claudin-1 in the colonic tissues were significantly increased(P<0.05, P<0.01). ConclusionAMR is able to improve the constipation symptoms in STC mice, and its mechanism may be related to increasing the contents of SCFAs in the intestine as well as promoting the mRNA and protein expression levels of ZO-1, Occludin and Claudin-1 in the colon.

Climate change has led to an increasing frequency and intensity of extreme climate events such as heat and drought extremes with considerable global public health burden. This systematic review collected 87 domestic and international studies from 2000 to 2023, considering the impacts of heat extremes, drought extremes, and compound hot-dry events on infectious diseases attributable to various transmission pathways such as waterborne, foodborne, insect-borne, airborne, and contact-transmitted diseases. Our results showed that high temperature was associated with increased transmission risks of waterborne and foodborne diseases including infectious diarrheal diseases (cholera, dysentery, typhoid, and paratyphoid) and infectious gastroenteritis; vector-borne diseases including dengue fever, Zika virus (ZIKV) disease, chikungunya fever, malaria, West Nile fever, and Rift Valley fever; airborne diseases including influenza-like diseases, influenza A, measles, and mumps; and contact-transmitted diseases including HIV/AIDS, schistosomiasis, and leptospirosis. Additionally, drought conditions also amplified the transmission risks of waterborne and foodborne diseases including cholera, Escherichia coli infection, rotavirus infection, and hepatitis E; vector-borne diseases such as scrub typhus, schistosomiasis, hemorrhagic fever with renal syndrome, and West Nile fever; airborne diseases including meningococcal meningitis, pertussis, measles, and upper respiratory infections; and contact-transmitted diseases such as HIV/AIDS. Along with global warming, the frequency of compound high temperature and drought events shows a considerably increasing trend, causing more adverse health effects than heat or drought alone. However, there is limited research quantifying their effects on infectious diseases. These associations may be mediated through temperature and precipitation on infectious disease pathogens, transmission vectors, population susceptibility, public health services, and behaviors. In the context of climate change, the increasing occurrence of compound events of high temperatures and droughts raises health concerns, and further studies are needed to enhance our understanding of the impacts of climate change on infectious diseases and improve human adaption to climate change.

Objective:
To analyze the burden indicators and trend predictions of eating disorders in Chinese adolescents aged 10-24 years from 1990 to 2019, so as to provide a reference for the prevention and control of eating disorders among adolescents.
Methods:
According to the latest data of the Global Burden of Disease Study(GBD) 2019 database classified by gender, age group and other indicators, the Joinpoint regression model and bayesian age period cohort model(BAPC) were used to analyze and predict the incidence rate, prevalence and disabilityadjusted life year (DALY) rate of eating disorders among Chinese adolescents aged 10 to 24 years old, and explore the trend of the disease burden of eating disorders in this population in the past three decades.
Results:
From 1990 to 2019, the overall crude incidence rate of eating disorders among adolescents in China increased from 278.93/105 to 422.27/105, and the crude incidence rate increased from 122.63/105 to 198.80/105, and the crude DALY rate increased from 26.67/105 to 43.50/105. In terms of gender, the standardized incidence rate, standardized prevalence rate and standardized DALY rate of eating disorders of boys and girls all showed an upward trend(boys:AAPC=1.52%,1.84%,1.86%,girls:AAPC=1.28%,1.74%,1.77%,P<0.05). The standardized incidence rate, standardized prevalence rate and standardized DALY rate of boys with eating disorders (54.97%, 68.88%, 69.75%) were higher than those of girls (44.26%, 64.48%, 65.56%), and the differences were statistically significant (χ2=201.45, 35.02, 34.55, P<0.05). In terms of age groups, the incidence rate of the 15-19yearold age group (524.10/105) was higher than that of other age groups (10-14yearold age:251.17/105, 20-24yearold age:476.49/105) (χ2=156.87, P<0.05), the prevalence rate of the 20-24yearold age group (278.67/105) and the DALY rate (60.83/105) were higher than those of other age groups (10-14yearold age:81.79/105,18.02/105, 15-19yearold age:221.81/105,48.59/105) (χ2=204.50,197.14, P<0.05). BAPC prediction model showed that in the future, the incidence rate of eating disorders among adolescents in China would still show an upward trend, but the prevalence rate and DALY rate would show a steady downward trend, which might reach 516.43/105, 188.41/105 and 41.23/105 respectively in 2030.
Conclusions
The burden of eating disorders among adolescents in China continues to increase, with boys and those aged 15-19 years being the key populations for prevention and treatment. All sectors of society should actively take relevant measures and pay attention to the prevention and treatment of adolescent eating disorders.
