The year 2025 marks the 110th anniversary of the Chinese Medical Association-a significant milestone in the history of medical science in China. Over the past century, the Association has witnessed and facilitated remarkable advances in medicine, uniting generations of medical professionals committed to safeguarding public health. As one of its leading academic journals, the Chinese Journal of Preventive Medicine, since its inception in 1953, has systematically documented the development of public health and preventive medicine in China-from the control of endemic diseases to the establishment of a modern public health system. Since 2008, in collaboration with the National Center for AIDS/STD Control and Prevention, China CDC, the Journal has published a decade-long series of annual special issues on HIV/AIDS prevention and control, comprehensively showcasing China's scientific progress and practical achievements in this field. These publications cover various domains, including epidemiology, behavioral interventions, policy evaluation, and health economics, collectively reflecting the evolution of prevention strategies. This article reviews the pivotal role of the Journal in advancing public health and disease prevention in China, underscores its academic influence and mission as a knowledge disseminator, and anticipates its ongoing contributions and innovations under the Healthy China 2030 initiative.

<p><p><b>Objective:</b> To analyze the distribution of allergens in patients aged 0-18 years with allergic diseases in Guangzhou City, and to investigate the distribution characteristics of serum specific immunoglobulin E (sIgE) and the sensitization patterns in this population. <b>Methods:</b> This cross-sectional study collected data on 4 001 patients aged 0-18 years who were diagnosed with allergic diseases in Guangdong Women and Children Hospital from March 2024 to February 2025 (2 430 males and 1 571 females; median age 2 years, mean age 1 year). The sIgE results for 7 inhalant allergens and 7 food allergens were obtained using the HAIKE ALLEOS 1200 fluorescent magnetic particle chemiluminescence method and analyzed. Chi-square tests/Fisher's exact tests were employed for intergroup comparisons, and Pearson correlation analysis was conducted to assess associations among different allergens. <b>Results:</b> Among the 4 001 patients, the main allergens identified were milk (2 571/4 001, 64.3%), egg white (1 664/4 001, 41.6%), <i>Dermatophagoides pteronyssinus</i> (<i>Der. pteronyssinus</i>) (554/4 001, 13.8%), wheat (244/4 001, 6.1%), and <i>Dermatophagoides farinae</i> (<i>Der. farinae</i>) (237/4 001, 5.9%). In different age groups, the <1 year group (infancy) and the 1-3 years group (toddler) primarily showed sensitization to milk (557/878, 63.4%) (1 792/2 291, 78.2%) and egg white (421/878, 47.9%) (1 010/2 291, 44.1%), with significant intergroup differences (<i>χ</i><sup>2</sup>=739.391, <i>χ</i><sup>2</sup>=116.77, both <i>P</i><0.001). The 4-6 years group (preschool) showed sensitivities mainly to <i>Der. pteronyssinus</i> (166/429, 38.7%), milk (164/429, 38.2%), egg white (161/429, 37.5%), and <i>Der. farinae</i> (79/429, 18.4%) (<i>χ</i><sup>2</sup>=1 166.793, <i>χ</i><sup>2</sup>=739.391, <i>χ</i><sup>2</sup>=116.77, <i>χ</i><sup>2</sup>=507.150, all <i>P</i><0.001); the 7-18 years group (school age and adolescence) showed sensitization mainly to <i>Der. pteronyssinus</i> (269/403, 66.7%), <i>Der. farinae</i> (120/403, 29.8%), egg white (72/403, 17.9%), and milk (60/403, 14.9%) (<i>χ</i><sup>2</sup>=1 166.793, <i>χ</i><sup>2</sup>=507.150, <i>χ</i><sup>2</sup>=116.77, <i>χ</i><sup>2</sup>=739.391, all <i>P</i><0.001).

The prevalence of allergic diseases is rising globally, including in China, and has become an increasingly serious public health issue. This consensus, developed by the Allergy Prevention and Control Committee of the Chinese Preventive Medicine Association, draws on international guidelines (such as EAACI standards) and Chinese research to systematically outline the principles and methods of allergen testing. It aims to standardize testing procedures and improve early diagnosis and precision treatment. Taking into account regional variations in climate, allergen distribution, and patient characteristics across China, the consensus proposes regionally tailored testing recommendations to promote standardized management of allergic diseases. It covers both traditional testing methods, such as skin prick tests,serum-specific immunoglobulin E testing (sIgE), and emerging molecular diagnostic technologies, emphasizing targeted strategies tailored to China's specific context. The consensus aligns with international standards while reflecting regional innovations, providing scientific guidance for clinical practice.

<p><p>This study analyzed the respiratory bacterial characteristics and antibiotic resistance of nursing home acquired pneumonia (NHAP) patients in social care nursing homes in Shanghai City, revealing a pathogen spectrum exhibiting features of both community-acquired pneumonia (CAP) and hospital-acquired pneumonia (HAP). These findings provide scientific evidence for clinical management and hospital infection control in similar community-run nursing homes and elderly care facilities. A retrospective method was employed to collect sputum samples from 945 NHAP patients at Shanghai Yingkang Nursing Home from January 2021 to December 2023. Bacterial cultures were used to detect bacteria, which were identified using the VITEK<sup>®</sup> 2 compact fully automated microbial analysis system, and antimicrobial susceptibility testing was conducted using the disk diffusion method. Analysis of bacterial distribution and antibiotic resistance was conducted using chi-square tests to compare differences in bacterial distribution among different age groups, patients with varying living statuses (bedridden <i>vs.</i> non-bedridden), and those with single or multiple bacterial infections. Results revealed a total of 1 702 bacterial isolates, with Gram-negative bacteria accounting for 80.7% (1 374/1 702). The predominant species were Pseudomonas aeruginosa (16.6%, 283/1 702), Klebsiella pneumoniae (16.1%, 274/1 702), Acinetobacter baumannii (14.8%, 252/1 702), and Escherichia coli (13.2%, 225/1 702). Gram-positive bacteria constituted 19.3% (328/1 702), predominantly Staphylococcus aureus (18.3%, 312/1 702). With Escherichia coli exhibiting resistance rates of >80% to penicillin (Ampicillin), cephalosporins, and aztreonam; Acinetobacter baumannii exhibiting resistance rates of >76% to carbapenems; and MRSA(Methicillin-resistance Staphylococcus aureus) accounting for 90.7% (283/312) of Staphylococcus aureus. Key resistance profiles varied, with Klebsiella pneumoniae exhibiting a resistance rate of 24.1% (66/274) to imipenem; Pseudomonas aeruginosa exhibiting a resistance rate of 49.8% (141/283) to imipenem; all Gram-positive cocci remained susceptible to vancomycin and linezolid. Population characteristics revealed that bacterial detection rates were 50.2% (854/1 702) among patients aged >84 years. With significantly increased detection rates for Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae across higher age groups (<i>χ</i>²=9.28, <i>P</i><0.05). Bacterial detection rates were significantly higher among long-term bedridden patients compared to non-bedridden patients [e.g., Acinetobacter baumannii: 78.2% (197/252) <i>vs.</i> 21.8% (55/252), <i>χ</i>²=46.6, <i>P</i><0.001]. The infection pattern was primarily single bacterial infection, accounting for 77.6% (734/945), with Staphylococcus aureus accounting for 30.4% (223/734); multiple infections were primarily Staphylococcus aureus+Pseudomonas aeruginosa combinations, accounting for 14.1

<p><p><b>Objective:</b> To characterize the epidemiology of allergic rhinitis (AR) in a tertiary hospital of Shanghai City and to describe the distribution and features of allergen-specific immunoglobulin E (sIgE) and total immunoglobulin E (tIgE), providing evidence to inform public-health prevention and clinical management. <b>Methods:</b> A retrospective study was conducted using data from 23 101 patients diagnosed with allergic rhinitis in the Eye & ENT Hospital of Fudan University from 2014 to 2024. Cases tested by enzyme-linked immunoassay were analyzed to summarize the distribution characteristics of allergic sensitization by gender, age, and season. Chi-square tests were applied to assess group differences, and multiple linear regression analyses were used to evaluate serum tIgE levels and their epidemiological patterns under exposure to different allergens. <b>Results:</b> Of the 23 101 patients with allergic rhinitis included in the study, 12 683 tested positive for at least one allergen, with inhalant allergens being the most common type. The overall sIgE positivity rate differed significantly by gender, age, and season. Males exhibited a higher positivity rate than females [56.31% (6 945/12 333) <i>vs.</i> 53.29% (5 738/10 768); <i>χ</i>²=21.2, <i>P</i><0.001]. The highest positivity rate was observed among patients aged 7-12 years [75.79% (3 359/4 432)], followed by those aged 13-18 years [72.73% (1 779/2 446); <i>χ</i>²=2 202.5, <i>P</i><0.001]. Seasonally, the highest sIgE positivity rate occurred in summer [60.64% (4 971/8 197); <i>χ</i>²=371.3, <i>P</i><0.001].Overall, the positivity rates for inhalant allergens [55.87% (6 891/12 333)] and food allergens [2.57% (317/12 333)] were both higher in males than in females [52.74% (5 679/10 768) and 1.84% (198/10 768)]. The positivity rate for inhalant allergens showed a gradual decline with age, whereas that for food allergens remained relatively stable after adulthood. Regarding seasonal variation, allergic rhinitis due to both inhalant [60.16% (4 931/8 197)] and food allergens [2.70% (221/8 197)] was most prevalent from June to August (summer).Analysis of specific sIgE responses revealed that mite mix [46.85% (10 823/23 101)], cat dander [12.65% (2 923/23 101)], and dog epithelium [5.33% (1 232/23 101)] were the predominant allergens. Among patients with positive allergy tests, the leading causes of grade 3 or higher severe allergic reactions were mite mix [61.91% (6 700/10 823)], cat dander [35.27% (1 031/2 923)], and artemisia pollen [31.76% (101/318)].Finally, tIgE analysis demonstrated that patients with food allergies (positive for any food allergen), those positive for a single food allergen (peanut or soybean), and those positive for a single respiratory allergen (elm pollen, artemisia pollen, mold mix, hop pollen, or ragweed pollen) exhibited significantly elevated tIgE levels (<i>P</i><0.05). <b>Conclusion:</b> Based on the analysis of clinical data from a large sample of pe

Regarding seasonal variation, allergic rhinitis due to both inhalant [60.16% (4 931/8 197)] and food allergens [2.70% (221/8 197)] was most prevalent from June to August (summer).Analysis of specific sIgE responses revealed that mite mix [46.85% (10 823/23 101)], cat dander [12.65% (2 923/23 101)], and dog epithelium [5.33% (1 232/23 101)] were the predominant allergens. Among patients with positive allergy tests, the leading causes of grade 3 or higher severe allergic reactions were mite mix [61.91% (6 700/10 823)], cat dander [35.27% (1 031/2 923)], and artemisia pollen [31.76% (101/318)].Finally, tIgE analysis demonstrated that patients with food allergies (positive for any food allergen), those positive for a single food allergen (peanut or soybean), and those positive for a single respiratory allergen (elm pollen, artemisia pollen, mold mix, hop pollen, or ragweed pollen) exhibited significantly elevated tIgE levels (<i>P</i><0.05). <b>Conclusion:</b> Based on the analysis of clinical data from a large sample of pe","PeriodicalId":24033,"journal":{"name":"中华预防医学杂志","volume":"59 12","pages":"2062-2071"},"PeriodicalIF":0.0,"publicationDate":"2025-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145811234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate the association of combined trajectories for triglyceride-glucose (TyG) index and serum uric acid with diabetic retinopathy (DR). A cohort study design was utilized, based on the physical examination data of the Beijing Physical Examination Centre from 2015 to 2023, with one physical examination per year. The trajectory groups for the first 4 years were determined by the dual group-based trajectory model. The Cox proportional hazard regression model was used to explore the association between different trajectory groups and DR incidence. The study included 2 978 patients with type 2 diabetes mellitus. During a median follow-up period of 3.95 years, 73 (2.5%) individuals developed DR. The majority were male, had a long duration of diabetes and a high baseline TyG index. The combined trajectory of the TyG index and serum uric acid allowed the whole population to be divided into three groups: the control group, with a total of 1 690 cases (56.7%) in which both TyG index and serum uric acid were at low levels; the high serum uric acid group, with a total of 786 cases (26.4%) in which serum uric acid was substantially elevated while the TyG index was mildly elevated; and the high TyG index group, with a total of 502 cases (16.9%) in which the TyG index was substantially elevated while serum uric acid was was mildly elevated. Compared with the control group, the high TyG index group had a higher risk of incident DR, with an effect value of [2.45 (95%CI: 1.26-4.75), P=0.008] from the Cox model fully adjusted for covariates, and the effect persisted after adjustment for the baseline TyG index and serum uric acid values (P=0.048); the high serum uric acid group was not found to be associated with the risk of incident DR (P>0.05). In conclusion, diabetic patients in the high TyG index trajectory group had a higher risk of DR incidence that persisted at mildly elevated blood uric acid, suggesting that diabetic patients should pay more attention to TyG index changes to prevent DR.

Allergen-specific IgE testing plays a critical role in the diagnosis and management of allergic diseases. Compared with traditional methods, quantitative IgE testing offers more precise diagnostic support, facilitates assessment of disease severity, guides personalized treatment, and improves the prediction of disease onset and prognosis. Given China's vast territory and regional diversity in geography, climate, dietary habits, and age distribution, the spectrum and prevalence of allergens vary significantly across populations. Therefore, the selection of allergens for testing should be guided by patients' clinical histories and regional epidemiological characteristics. Broad, non-targeted screening may lead to misinterpretation of allergen sensitization results. This article integrates epidemiological data and age stratification with quantitative allergen-specific IgE testing to standardize allergen testing practices and promote precision diagnosis and treatment of allergic diseases.

Objective: To explore the correlation between neutrophil percentage to high-density lipoprotein cholesterol ratio (NHR) and coronary artery stenosis (CAS)≥50% in patients with controlled low-density lipoprotein cholesterol (LDL-C) <2.60 mmol/L. Methods: This study enrolled patients with controlled LDL-C who had been diagnosed with CAS disease at the Department of Cardiology, TEDA International Cardiovascular Hospital, between January and December 2013. Participants were stratified into two groups based on coronary angiography results: the CAS ≥50% group and the CAS <50% group. General clinical data, laboratory parameters, and NHR of patients were compared between the two groups. Logistic regression analysis was utilized to identify factors associated with CAS ≥50% in patients with controlled LDL-C. A receiver operating characteristic (ROC) curve was performed to evaluate the predictive value of these associated factors. The DeLong test was applied to compare the predictive efficacy among different models based on the ROC curves. Decision curve analysis (DCA) was employed to assess the benefits of the models in clinical decision-making. Results: A total of 467 subjects were enrolled, including 317 in the CAS ≥50% group and 150 in the CAS <50% group. The NHR in the CAS ≥50% group (67.15±20.31) was significantly higher than that in the CAS<50% group (58.24±17.59, t=4.615, P<0.001). Elevated NHR was an associated factor for CAS ≥50% with controlled LDL-C [OR=1.015, 95%CI: 1.003~1.027, P=0.016]. A ROC model integrating NHR, aspartate aminotransferase mitochondrial isoenzyme (ASTm), diabetes mellitus, and smoking history for predicting CAS≥50% in patients with controlled LDL-C had an area under the curve of 0.716, with a sensitivity of 61.50%, a specificity of 71.70%, and a Youden's index of 0.332. The DeLong test demonstrated that the integrated model exhibited significantly superior performance compared to the single NHR model (Z=3.765, P<0.001). Furthermore, DCA demonstrated that the integrated model can provide net benefits for clinical decision-making within a threshold probability range of 0.12~0.60. Conclusion: In patients with coronary artery lesions in whom LDL-C levels are controlled, elevated NHR is an associated factor for the occurrence of CAS≥50%. The model integrating NHR, ASTm, diabetes mellitus, and smoking history exhibits a certain predictive effect on disease.

Objective: To analyze the epidemiological characteristics and intervals of onset-to-diagnosis and diagnosis-to-report for meningococcal meningitis in Zhejiang Province from 2014 to 2024. Methods: Meningococcal meningitis case data were collected from the National Notifiable Disease Reporting System (NNDRS) and the Meningococcal Meningitis Surveillance Information Management System in Zhejiang Province (2014 to 2024). The Mann-Whitney U test and Kruskal-Wallis H test were used to compare the differences in the onset-to-diagnosis time among case groups with different characteristics. Results: From 2014 to 2024, Zhejiang Province reported 45 meningococcal meningitis cases (3 deaths), with a case fatality rate of 6.67%. The average annual incidence and mortality rates were 0.065 per million and 0.004 per million, respectively. The mean annual age-specific incidence rates for the 0-4, 5-9, 10-14, and ≥15-year-old groups were 0.793, 0.063, 0.074, and 0.032 per million, respectively. Of 39 isolated strains, serogroup B dominated (53.85%, 21 strains), followed by Y (10.26%, 4), C (10.26%, 4), W (7.69%, 3), and non-groupable strains (17.95%, 7). Among the 0-4-year-old group, serogroup B accounted for 75.00% (15/20 strains). The median onset-to-diagnosis interval M (Q1,Q3) was 6 (3, 8) d, while the diagnosis-to-report interval was 0 (0, 0) d. For cases with petechiae/purpura, the median onset-to-diagnosis interval was 3 (2, 6) d, while for cases without petechiae/purpura, it was 6 (5, 10) d, with a statistically significant difference (U=134.50, P=0.008). Conclusion: From 2014 to 2024, the incidence of meningococcal meningitis in Zhejiang Province remains low. In the general population, serogroup B is the predominant strain, with co-circulation of multiple serogroups including Y, C, and W. The 0-4-year-old group has a relatively higher incidence, with serogroup B being the predominant strain in this age group. In the future, more efforts should be devoted to strengthen the sensitivity of monitoring for meningitis and improve the ability of medical institutions to differentiate and diagnose atypical symptoms of meningitis.

Objective: To conduct a molecular epidemiological investigation and genetic characteristics of the local outbreak of Chikungunya fever in Guangzhou City in July 2025, clarify the source, genotype, and variation characteristics of the virus, and provide a scientific basis for traceability and prevention and control of the outbreak. Method: Epidemiological data and serum samples of confirmed cases were collected. The virus nucleic acid testing, whole genome sequencing, phylogenetic tree reconstruction, and E1/E2 protein amino acid site analysis were performed. Results: By August 6, 2025, 104 autochthonous Chikungunya cases had been confirmed in Guangzhou City, showing a spatially scattered transmission pattern with limited cluster potential in areas such as Xintang Town. Fifty-one full-genome sequences were obtained, all belonging to the East/Central/South African (ECSA) genotype, Central African subclade, with a similarity of 99.96% to the Réunion Island strains (2024-2025). Fifteen amino acid mutations were identified in E1/E2 proteins, of which 13 were unique, including adaptive mutations such as E1-A226V and E2-I211T. Conclusion: The outbreak is caused by a single imported ECSA-genotype strain, potentially from the Indian Ocean region. There may be a risk of small-scale outbreaks in Guangzhou City. Continuously strengthening mosquito-borne disease surveillance, early warning systems, and etiological monitoring is significant for disease prevention and control.
