To investigate the distribution and development of common allergens in children in Hangzhou area, and to provide an epidemiological basis for the prevention, diagnosis, and treatment of allergic diseases in this area. This study is a retrospective study, selecting 3 524 children who underwent allergen screening at DiAn Medical Laboratory Center (Hangzhou) Co., Ltd. from January 2022 to January 2024 as the research subjects, including 2 012 males and 1 512 females. Among them, there were 1 098 infants (0-1 year olds), 1 673 toddlers (1-3 year olds), and 753 children (3-14 year olds). Immunoblotting was used to detect 21 allergen-specific immunoglobulin E (sIgE) antibodies. The positive rates of various allergens were calculated according to gender, age, and other factors, and the epidemiological characteristics and trends were analyzed. The results showed that the overall positive rate of sIgE was 60.33% (2 126/3 524). The main inhaled allergens were Dermatophagoides pteronyssinus/Dermatophagoides farinae (992, 28.15%), dog dander (295, 8.37%) and cat dander (181, 5.13%). The main food allergens were milk (696, 19.75%), egg white (541, 15.36%) and shrimp (205, 5.83%). Boys had significantly higher sIgE positivity rates than girls for Dermatophagoides pteronyssinus/Dermatophagoides farinae(642, 31.90%, χ2=10.10, P=0.001), house dust(61, 3.02%, χ2=5.12, P=0.024), cat dander(124, 6.16%, χ2=4.06, P=0.044), mold combinations(103, 5.14%, χ2=7.51, P=0.006), and tree pollen combinations(42, 2.07%, χ2=5.44, P=0.020) (all P<0.05); With age, there was a significant increase in positivity rates for house dust mite/dust mite, house dust, mold combinations, milk, and beef (all P<0.05), and a significant decrease in positivity rates for cockroach consumption, egg whites, shrimp, crab, cod, lobster/scallop, and soybeans (all P<0.05), the positive rates of only ingestive allergens decreased significantly ( P<0.001), and the positive rates of only inhalant and mixed allergens increased significantly ( P<0.001). In conclusion,in the Hangzhou area, dust mites are the most common inhalant allergens among children with allergic diseases, while milk is the most common food allergen. Boys are more sensitive to inhalant allergens, and as children grow older, the positive rates for different allergens undergo significant changes. Dynamic monitoring of changes in specific IgE antibodies to various allergens can assist in the diagnosis, prevention, and treatment of allergic diseases.

Objective:To analyze the epidemiological and clinical characteristics of respiratory pathogens in China.Methods:This study was a cross-sectional study, which encompassed 19 core units of the clinical pathogen network and established a three-tiered clinical pathogen surveillance system. Thirty respiratory samples were collected every two weeks from various units from January to December 2024, and the clinical and pathogen diagnostic information were gathered. A total of 11 864 samples were tested using this system. The tier-1 clinical pathogen surveillance system covered influenza A virus (Flu-A), influenza B virus (Flu-B), respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The tier-2 clinical pathogen surveillance system focused on 18 key respiratory pathogens. The tier-3 clinical pathogen surveillance system further clarified whether any emerging infectious diseases had occurred.Results:The tier-1 clinical pathogen surveillance system showed Flu-A predominated in December, Flu-B predominated in January, SARS-CoV-2 peaked in March and August, whereas RSV circulated sporadically throughout the year. Geographic trends were broadly consistent across the seven major regions, although Flu-A detection in December was notably higher in Northeast China (48.1%(111/231)) and East China (36.2%(148/409)), and RSV detection was concentrated in the Northwest and South China from January to March. Data from the tier-2 clinical pathogen surveillance system indicated that Streptococcus pneumoniae, Mycoplasma pneumoniae, rhinovirus, and adenovirus were detected year-round, of these, Streptococcus pneumoniae and rhinovirus showed elevated positive detection rates from August to September, while adenovirus peaked in January. Legionella pneumophila was not detected throughout the year, and other pathogens fluctuated throughout the year without a consistent pattern. The predominant etiologic agents of pediatric pneumonia were Mycoplasma pneumoniae (35.0%(105/300)), rhinovirus (25.7%(77/300)), and adenovirus (17.3%(52/300)), whereas adult pneumonia was mainly caused by Streptococcus pneumoniae (10.5%(29/277)), Staphylococcus aureus (6.9%(19/277)), Mycoplasma pneumoniae (6.9%(19/277)), and Flu-A (6.1%(17/277)). The tier-3 clinical pathogen surveillance system did not identify any emerging respiratory pathogens. Conclusion:Respiratory pathogens in China in 2024 exhibit distinct temporal and spatial distribution patterns and vary among different populations.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To investigate the improvement in nutritional indicators, clinical complications, and respiratory infections among children with cerebral palsy (CP) and malnutrition who meet the indications for tube feeding under oral feeding and tube feeding interventions.Methods:In this retrospective cohort study, 82 children with CP and malnutrition that met the indications for tube feeding from the Children′s Rehabilitation Hospital of the Third Affiliated Hospital of Zhengzhou University from January 2022 to April 2024 were included.These patients were divided into an oral feeding group and a tube feeding group.The t-test, Mann-Whitney U test, or Kruskal-Wallis test was used to analyze nutritional indices such as weight-for-age Z-score (WAZ), height/length-for-age Z-score (HAZ), and weight-for-height/length Z-score (WHZ) before and after intervention in both groups.The improvement in clinical complications and respiratory infections was also analyzed. Results:After 3-month nutritional intervention, there were 60 cases in the oral feeding group and 22 cases in the tube feeding group.The tube feeding group showed better improvement in WHZ [-0.23(-1.79, 0.88) vs.-1.62(-2.02, -0.91) ] than the oral feeding group ( P<0.05).After 6-month nutritional intervention, there were 50 cases in the oral feeding group and 16 cases in the tube feeding group.The tube feeding group showed better improvement in WAZ [-0.80(-1.92, -0.42) vs. -2.26(-2.88, -1.84)], HAZ (-1.31±1.23 vs. -2.32±1.19), and WHZ (-0.74±1.39 vs. -1.58±1.03) than the oral feeding group (all P<0.05).After 12-month nutritional intervention, there were 30 cases in the oral feeding group and 10 cases in the tube feeding group.The tube feeding group showed better improvement in WAZ [-1.06(-1.77, -0.88) vs.-2.25(-3.06, -1.47) ] and HAZ (-1.22±1.63 vs. -2.54±1.50) than the oral feeding group (all P<0.05).Clinical complications improved better in the tube feeding group than those in the oral feeding group.In the tube feeding group, significant differences in choking ( χ2=16.29, P=0.001) and vomiting ( χ2=6.81, P=0.013) were observed before and after nutritional intervention.There was a statistically significant difference in frequency of lower respiratory infections 3 and 6 months after nutritional intervention between the 2 groups (all P<0.05). Conclusions:Compared with oral feeding, tube feeding can effectively improve the clinical nutritional indicators and reduce the clinical complications and the risk of respiratory infections in CP children that meet the indications for tube feeding.

The enterotoxigenic Escherichia coli (ETEC) infection is a major factor restricting the development of animal husbandry. However, the abuse of antibiotics will lead to the antibiotic residues and emergence of antibiotic-resistant bacteria. The existing vaccines face challenges in stimulating intestinal immunity, demonstrating limited prevention effects. Therefore, it is indispensable to develop a new vaccine that is safe and suitable as a feed additive to activate intestinal immunity. This study constructed yeast-cell microcapsules (YCM) carrying the DNA vaccine against ETEC by genetic engineering. Furthermore, animal experiments were carried out to explore the regulatory effects of feeding YCM on the intestinal immune system and intestinal microbiota. Saccharomyces cerevisiae was selected as the oral delivery vehicle (microcapsules) of the DNA vaccine. The codon-optimized nucleic acid sequence of K88, the main antigen of mammal-derived ETEC, was synthesized, and the yeast shuttle vector containing the corresponding DNA vaccine expression cassette was constructed by DNA recombination. The recombinant strain of YCM was prepared by transforming JMY1. Additionally, the characteristics of the YCM strain and its feasibility as an oral vaccine were comprehensively evaluated by the fluorescence reporter assay, gastrointestinal fluid tolerance assay, intestinal epithelial cell adhesion assay, intestinal retention assessment, antiserum detection, and intestinal microbiota detection. The experimental results showed that the DNA vaccine expression cassette was expressed in mammals, and the recombinant strain of YCM could tolerate up to 8 hours of gastrointestinal fluid digestion and had good adhesion to intestinal epithelial cells. The results of mouse feeding experiments indicated that the recombinant strain of YCM could stay in the intestinal tract for at least two weeks, and the DNA vaccine expression cassette carried by YCM entered the intestinal immune system and triggered an immune response to induce the production of specific antibodies. Moreover, feeding YCM recombinant bacteria also improved the abundance of gut microbiota in mice, demonstrating a positive effect in regulating intestinal flora. In summary, we prepared the recombinant strain of YCM carrying the DNA vaccine against ETEC and comprehensively evaluated its characteristics and feasibility as an oral vaccine. Feeding the recombinant YCM could induce specific immune responses and regulate intestinal microbiota. The findings provide a reference for the immunoprevention of ETEC-related animal diseases.
