The prevalence of food allergy in children is increasing, which seriously affects the quality of life of children and their families. Among children and adolescents, IgE-mediated food allergy is the most common type. In recent years, allergen specific IgE (sIgE) and skin prick testing (SPT) have been widely used in clinical practice, with component resolved diagnosis (CRD) also gaining traction for precise diagnosis of IgE-mediated food allergy. However, a challenge persists in clinical practice due to the tendency to over-interpret food allergen test results without considering the patient's clinical history. While food avoidance remains the most effective treatment for IgE-mediated food allergy, there are varying approaches to clinical management. Strict food avoidance for non-severe food allergies may increase the patient's burden and impact their quality of life. To address these challenges, a consensus on the diagnosis and management of IgE-mediated food allergy in children has been developed based on the latest guidelines and research evidence. This consensus aims to guide physicians in standardizing the management of IgE-mediated food allergy in children.

To analyze the disease burden of Alzheimer's disease (AD) in China from 1990 to 2021 and its trend of change, providing evidence for targeted interventions to reduce the burden of AD. A descriptive analysis of AD and its main risk factors among males and females of different ages in China from 1990 to 2021 was conducted using the Global Burden of Disease (GBD) 2021 database. The evaluation indicators were incidence rate, prevalence rate, mortality rate, and disability-adjusted life years (DALYs). The risk factors included high body mass index (BMI), high fasting plasma glucose, and smoking. The results showed that in 2021, the number of AD incidence among the Chinese population was 2 914 112 (204.8/100 000), the number of prevalence was 16 990 827 (1 194.2/100 000), the number of DALYs was 10 072 477 (708.0/100 000), and the number of deaths was 491 773 (34.6/100 000), which increased by 242.7%, 249.1%, 208.2%, and 239.4% respectively compared with 1990. In 2021, the AD incidence rate (264.4/100 000), prevalence rate (1 558.9/100 000), DALYs rate (935.8/100 000), and mortality rate (47.3/100 000) were all higher in women than in men. All rates showed a clear age-dependent trend. In 2021, the DALYs attributable to smoking, high BMI, and high fasting plasma glucose in the AD population in China were 602 501.1 (42.3/100 000), 466 728.7 (32.8/100 000), and 1 204 039.4 (84.6/100 000), respectively, with death tolls of 24 897.3 (1.7/100 000), 20 856.3 (1.5/100 000), and 58 838.2 (4.1/100 000). The proportion of DALYs attributable to high BMI showed an upward trend during 1990-2021, while the proportion of DALYs attributable to smoking showed a gradual decrease. The difference in the attributable risk factors between the genders was significant. In 2021, the highest risk among men was attributed to smoking, with DALYs rate and mortality rate of 68.3/100 000 and 2.7/100 000, respectively. In contrast, the highest risk among women was attributed to high fasting blood sugar, with DALYs rate and mortality rate of 111.1/100 000 and 5.6/100 000, respectively. In conclusion,the disease burden of AD is still increasing, and targeted interventions should be taken for both males and females to reduce the burden of AD by reducing unhealthy lifestyles.

Autoantibody detection is important in the diagnosis, classification, condition assessment and therapeutical effect monitoring of autoimmune disease.

Bones possess metabolic activity, with their homeostasis maintained by bone resorption and bone formation mediated by osteoclasts and osteoblasts. By measuring bone metabolism markers, the overall state of bone metabolism and dynamic changes in systemic bone tissue can be reflected. Traditional bone turnover markers, including alkaline phosphatase, bonespecific alkaline phosphatase, procollagen type 1 N-terminal propeptide, procollagen type 1 C-terminal propeptide, osteocalcin, c-terminal telopeptides of type 1 collagen(CTX) and its subtype β-CTX, n-terminal telopeptides of type 1 collagen, have been widely used in clinical practice but still have limitations in terms of stability, diagnostic reliability, and specific reflection of bone sites. Recently, novel bone turnover markers like microRNA, C-X-C chemokine ligand 12, Gelsolin, Annexin A2, sclerostin, Dickkopf-related protein 1, and citrate have garnered significant attention. This article endeavors to conduct a review of the production, mechanism of action, detection methods, diagnostic value, and application prospects of new bone turnover markers in osteoporosis, thereby offering novel ideas for the prevention, diagnosis, and treatment of osteoporosis.

Allergic reactions are abnormal responses of the immune system to specific allergens, typically resulting in the release of inflammatory mediators and tissue damage. Cardiovascular diseases are common conditions that contribute significantly to increased mortality rates, with inflammation-induced tissue damage playing a crucial role in their pathogenesis. Allergic reactions are associated with various aspects of cardiovascular diseases, such as hypertension, atherosclerosis, and cardiac remodeling. Certain allergic conditions may increase the risk of cardiovascular disease onset. This article aims to explore the role of inflammatory mediators in allergic reactions within the pathophysiology of common cardiovascular diseases. By doing so, it seeks to uncover potential links between allergic reactions and cardiovascular diseases, offering new insights for the prevention and treatment of related conditions.

Objective: The objective of this research is to study the prevalence and risk factors of psychosocial and behavioral problems in children and adolescents of different ages and genders to provide a scientific foundation for more targeted psychological interventions and social support in the future. Methods: From April 21 to May 31, 2023, a cross-sectional survey was conducted using a stratified random sampling method in five cities (Beijing City, Changchun City, Baicheng City, Shenyang City, Hohhot City) across four provinces in Northern China (Beijing, Jilin, Liaoning, Inner Mongolia). The study was conducted using an online questionnaire among children and adolescents aged 6-16 years. Self-made social and life characteristics questionnaire and Achenbach Child Behavior Check List (CBCL) (for parent) was utilized to investigate the prevalence of psychosocial and behavioral problems and relative influencing factors. Using stepwise regression analysis to screen potential factors affecting the psychosocial and behavioral health of children and adolescents and logistic regression analysis was employed to analyze the risk factors associated while controlling for confounding variables. Results: A total of 10 492 questionnaires were distributed in this study. Among the 8 593 valid questionnaires collected, there were 4 385 males (51.03%) and 4 208 females (48.97%). The sample consisted of 3 348 children aged 6-11 years old and 5 245 children aged 12-16 years old. Out of these participants, 688 individuals (8.01%) were detected positive. In the 6-11 age group, 1 762 boys were assessed, revealing 142 positive cases (8.06%), while 1 586 girls were assessed, with 84 positive cases (5.30%). In the 12-16 age group, 2 623 boys were evaluated, resulting in 237 positive cases (9.04%), and 2 622 girls were evaluated, with 225 positive cases (8.58%). Overall, boys had a higher prevalence rate than girls did, with older age groups showing higher rates compared to younger ones. Logistic regression analysis identified six significant risk factors: parent-child conflict (OR=4.207, 95%CI: 3.583-4.940), irregular diet patterns(OR=1.862, 95%CI: 1.566-2.213), parental mental illness history(OR=5.381, 95%CI: 2.673-10.83), sleep disorders(OR=4.664, 95%CI: 4.194-5.187), and excessive screen exposure(OR=1.863, 95%CI: 1.577-2.200) were found to be risk factors; whereas having more close friends (OR=0.510, 95%CI: 0.431-0.603) acted as a protective factor. Conclusions: Psychosocial and behavioral problems in children and adolescents will change with social conditions, with continuous attention required to prevent risk factors. Precise intervention and integral support should be implemented by families, schools and society to provide more accurate protection for children and adolescents.

From June to September 2021, residents aged 15-65 years from 18 provincial cities and 10 directly administered counties (cities) in Henan Province were collected for a questionnaire survey, so as to understand the status quo of the knowledge and related influencing factors of hepatitis C prevention and treatment. Among 11 627 subjects, the adjusted awareness rate of knowledge about hepatitis C prevention and treatment was 59.2% (95%CI: 58.3%-60.1%). The awareness rate was higher among people aged 15-24 years [63.7% (95%CI: 61.4%-66.1%)] and those with education level of college or above [72.8% (95%CI: 70.8%-74.8%) (both P<0.05). The multivariate logistic regression model analysis showed that compared with urban and aged 15-24 years residents, rural, aged 25-34 years, 35-44 years, 45-54 years, and 55-65 years residents had lower awareness rates, with OR (95%CI) values of 0.825 (0.754-0.902), 0.733 (0.624-0.863), 0.746 (0.626-0.889), 0.766 (0.643-0.912), and 0.580 (0.484-0.695), respectively; compared with unmarried, junior high school and below residents, marriage/cohabitation, high school or vocational school, college or above residents had higher awareness rates, with OR (95%CI) values of 1.523 (1.315-1.764), 1.624 (1.474-1.789) and 2.212 (1.945-2.516), respectively.

Soybeans and peanuts belong to the leguminous family and are common causes of food anaphylaxis. Symptoms range from oral allergy syndrome to severe breathing difficulties, anaphylactic shock, and even death. But the allergens causing allergies are different, and the severity of symptoms are different. Precise diagnosis at the molecular level or component-resolved diagnosis (CRD) is necessary. CRD is a technology that accurately identifies allergen proteins to help physicians personalize clinical treatment and management strategies for allergy patients. In this article, according to the European Academy of Allergy and Clinical Immunology (EAACI) issued the "Allergen Component Diagnostic Guidance Recommendation 2.0 (MAUG 2.0)", it introduces the soy and peanut allergenic components, clinical diagnosis, treatment and management, aimed at improving the accurate diagnosis and personalized treatment of soy and peanut allergy.
