Objective:To analyze the distribution of allergen components of dust mite in children with airway allergic diseases.Methods:This was a cross-sectional study. The clinical data of children with dust mite-induced allergic asthma (AA) complicated with allergic rhinitis (AR) or allergic rhinitis who were treated in Department of Allergy,Beijing Children′s Hospital from January 2019 to October 2022 were retrospectively analyzed. The spedific IgE (sIgE) levels to Der p1,Der p2,Der p5,Der p7,Der p10,Der p21,Der p23 and Der f1,Der f2 were detected by protein chip method. The distribution of dust mite sensitized components and the sIgE levels in children with different airway allergic diseases and different ages were compared.Results:Among 138 children with airway allergic diseases,there were 97 boys and 41 girls,age (6.86±2.61) years old,and there were 106 cases of AA combined AR (AAAR group) and 32 cases of AR alone (AR group). The sensitization rates of Der p2 was the highest (75.4%,104/138),followed by Der f2 (74.6%,103/138),Der f1 (73.9%,102/138),Der p1 (71.7%,99/138),Der p21 (19.6%,27/138),Der p5 (16.7%,23/138),Der p23 (14.5%,20/138),Der p7 (11.6%,16/138) and Der p10 (2.9%,4/138). The co-sensitization rate of Der p1,Der p2,Der f1 and Der f2 was the highest (31.2%,43/138). There was no significant difference in sensitization rate of dust mites components between AAAR group and AR group(all P>0.05). AAAR group had higher levels of sIgE to Der p23 than AR group [0.1 (0,0.1) IU/ml vs. 0 (0,0.1) IU/ml,Z=-2.819, P=0.005]. There were no significant differences in the positive rate of dust mite components and sIgE levels between children aged≤6 and>6 years old with airway allergic diseases(all P>0.05). Conclusions:Der p1,Der p2,Der f1 and Der f2 are the major components of dust mites sensitizing airway allergic diseases in children. Der p1,Der p2,Der f1 and Der f2 are the main co-sensitizing components in children with dust mite-induced airway allergic diseases. Compared with AR,the sIgE level to Der p23 in children with AAAR is higher.

Serotonin syndrome (SS), also known as serotonin toxicity, is a rare but life-threatening drug reaction syndrome. This case involves a 17-year-old female patient who developed tremors, fatigue, and tachycardia after taking fluoxetine combined with bupropion and tandospirone for five days. SS was highly suspected, and her symptoms improved following treatment targeted at serotonin syndrome. This case is reported to raise awareness among clinicians about the potential adverse reactions of drug combinations, the importance of early identification of SS symptoms, and precautions when prescribing combined medications to avoid serious consequences.

Objective To explore the application effectiveness of the"three-early education"model in professional quality education for medical psychology students.Methods Two groups were studied:medical psychology undergraduates of grade 2017 under conventional teaching and medical psychology undergraduates of grade 2019 under the"three-early education"model.Surveys were distributed at the end of the third academic year to evaluate their participation in research,clinical activities,and social practices,along with their satisfaction regarding the educational arrangement.Results Students from the grade 2019 cohort who received"three-early education"exhibited significantly higher rates of participation in research projects,clinical studies,and community engagement than students from the grade 2017 cohort who received traditional education(P＜0.05).In comparison to the grade 2017 cohort,the grade 2019 cohort showed significantly increased satisfaction levels in curriculum design,scheduling,evaluation methods,and professional proficiency(P＜0.05).Conclusion The"three-early education"model enhances the practical engagement and teaching satisfaction of medical psychology undergraduates,thereby improving their professional competence in the field of medical psychology.

Pseudopleuronectes yokohamae is an important marine economic fish species in northern China and is vulnerable to various pathogens during the breeding process.To investigate the viru-lence of Edwardsiella tarda on Pseudopleuronectes yokohamae and elucidate the role of miRNAs in their interaction,we conducted pathological analyses on various tissues of Pseudopleuronectes yokohamae larvae pre-and post-infection with Edwardsiella tarda.Subsequently,Illumina high-throughput sequencing was employed to identify and functionally characterize differentially ex-pressed miRNAs in liver and kidney tissues.The results demonstrated that infection with Ed-wardsiella tarda led to ulceration,hemorrhaging,significant hepatomegaly,nephromegaly,and as-cites in the abdominal cavity.Histopathological examination revealed swollen hepatocytes with vac-uolization,minor blood cell infiltration,and enlarged renal corpuscles with signs of cellular lysis.miRNA sequencing analysis indicated that 24 miRNAs were significantly upregulated and 45 miR-NAs were significantly downregulated in the liver,while in the kidney,6 miRNAs were upregulat-ed and 58 were downregulated following infection.Functional enrichment analysis revealed signifi-cant enrichment of differentially expressed miRNAs in Toll and IMD signaling pathways,HIF-1 signaling pathway,Rap1 signaling pathway,MAPK signaling pathway,and Apelin signaling path-way.These findings suggest the involvement of these miRNAs in host metabolism,pathogen rec-ognition,and immune response in the interaction between Pseudopleuronectes yokohamae and Ed-wardsiella tarda.This research lays a foundation for elucidating the mechanisms underlying bacte-rial disease susceptibility and resistance in Pseudopleuronectes yokohamae.
