Introduction: In-depth analysis of the rambling genes of atopic dermatitis may help to identify the pathologic mechanism of this disease. However, this has seldom been performed.
Aim: Using bioinformatics approaches, we analysed 3 gene expression profiles in the gene expression omnibus (GEO) database, identified the differentially expressed genes (DEGs), and found out the overlapping DEGs (common DEGs, cDEGs) in the above 3 profiles.
Material And Methods: We identified 91 upregulated cDEGs, which were then arranged into a protein-protein interaction (PPI) network, and Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway and Gene Ontology (GO) term enrichment analyses were performed to explore the functional roles of these genes.
Results: GO analyses revealed these DEGs to be significantly enriched in biological processes including immune system process, immune response, defence response, leukocyte activation, and response to the biotic stimulus. These DEGs were also enriched in the KEGG pathway, including influenza A, amoebiasis, primary immunodeficiency, cytokine-cytokine receptor interaction, and IL-17 signalling pathway. PPI analysis showed that 9 genes (PTPRC-CTLA4-CD274-CD1C-IL7R-GZMB-CCL5-CD83, and CCL22) were probably the novel hub genes of atopic dermatitis.
Conclusions: Together, the findings of these bioinformatics analyses thus identified key hub genes associated with AD development.

Atopic dermatitis (AD) is a chronic and inflammatory skin disorder characterized by impaired barrier function and imbalanced immunity. Recent advances have revealed that dysbiosis of skin microbiota plays important roles in the pathogenesis and development of AD. Meanwhile, endogenous and external factors contribute to the dysbiosis of skin microbiota in AD.

Introduction: Due to their widespread character, allergic diseases are a significant challenge in the field of public health and clinical practice. The available clinimetric tools, including standardized and validated questionnaires, play an important role in determining the incidence of a particular allergic disease in the targeted population.
Aim: We attempted to evaluate the specificity and sensitivity of modified and standardized questions from the ISSAC and ECRHS questionnaires in the diagnosis of allergic diseases.

Atopic dermatitis (AD) is difficult to cure as a chronic inflammatory skin disease. In the present study, a series of N-heterocyclic functionalized chalcone derivatives have been prepared to investigate their in vitro and in vivo anti-inflammatory activities. The results indicated that many derivatives could effectively inhibit NO generation with low toxicity.
