Abstract: Objective: To analyze the related information of salivary differential proteins between OSAHS children and non-OSAHS children through proteomics detection technology. Methods: Saliva samples were collected from 6 children with OSAHS [5 males and 1 female, with an average age of (12.00±2.71) years] and 6 non-OSAHS healthy children [3 males and 3 females, with an average age of (10.22±2.05) years]. Total proteins were extracted, data-independent acquisition (DIA) mass spectrometry analysis and protein identification of differential proteins were performed, and finally bioinformatics analysis was conducted on the screened differential proteins. Results: 5636 proteins were identified in the non-OSAHS group and 5608 proteins in the OSAHS group, among which 5582 proteins were present in all groups. A total of 303 up-regulated proteins and 185 down-regulated proteins were screened out as significant differences between the two groups, among which several proteins with significant differences, such as KRT80, CXCL10, KRT19, and SAA2, were selected. Conclusion: There are differences in salivary proteins between OSAHS children and non-OSAHS children, and OSAHS molecular markers may be closely related to its occurrence, development, and pathogenesis.
