Abstract:
Objective:To explore the level of expression, clinical significance of receptor-interacting protein kinase-3(RIPK3) in the bronchoalveolar alveolar lavage fluid (BALF) of mycoplasma pneumoniae pneumonia(MPP) in children and the relationship between RIPK3 and various cytokines.Methods:Using a case-control study, 30 refractory mycoplasma pneumoniae pneumonia children treated in Children′s Hospital of Xuzhou Medical University from February 2019 to February 2021 were selected as the MRPP group, 35 mycoplasma pneumoniae pneumonia children as the RPP group.Meanwhile, 20 sex- and age-matched hospitalized children with bronchial foreign body were selected as the case-control group.In all subjects, protein levels of RIPK3 and mixed lineage kinase domain-like protein(MLKL) were determined by Western Blot.Meanwhile, levels of IL-6, IL-1β and TNF-α were determined by enzyme linked immuno sorbent assay(ELISA). Compare levels of different parameters between the three groups and analyze the correlation between levels of RIPK3 and MLKL, L-6, IL-1β, TNF-α in the BALF of MPP children using Spearman rank correlation analysis.Results:There were statistically significant differences in the levels of RIPK3, MLKL, IL-6, IL-1β and TNF-α in BALF between RMPP group, MPP group and control group (all P<0.001). Pairwise comparisons also showed statistical differences, and the RMPP group was the highest, followed by MPP group, and the control group was the lowest.The level of RIPK3 in BALF of MPP children was positively correlated with MLKL, IL-6, IL-1β and TNF-α ( r=0.711, 0.676, 0.725, 0.651, P<0.001). Linear regression analysis shows: MLKL=0.432×RIPK3. Conclusion:RIPK3 may be involved in the occurrence and development of MPP in children, and is closely related to cytokines such as IL-6, IL-1β and TNF-α.
