Abstract:
Objective:To detect the expression level of vitamin D receptor(VDR) in children with hand, foot, and mouth disease(HFMD), and explore its potential value in the diagnosis and treatment of children with HFMD.Methods:A total of 82 children with HFMD hospitalized in the Second Affiliated Hospital of Xi′an Jiaotong University and Xi′an Children′s Hospital from May 2017 to May 2019 were selected as the case group.At the same time, 42 healthy children who underwent physical examination in the Child Health Department during the same period were randomly selected as the control group.Peripheral blood of two groups of children was extracted to detect and compare the expression levels of VDR mRNA in mononuclear cells, and the correlation between the expression level of VDR and HFMD and the correlation with various clinical characteristics were analyzed.Results:The relative expression of VDR in children with EV71 HFMD was 2.03%±0.38%, which was lower than that in children of control group(3.11%±1.29%), and the difference was statistically significant( t=-3.586, P=0.001). However, the relative expression of VDR in children with CA16 HFMD was 3.69%±1.79%, which was higher than that in children of control group, and the difference was not statistically significant( t=1.043, P=0.305). Among children with EV71 HFMD, the relative expression level of VDR was significantly different between the mild group and the severe group(2.18%±0.44% vs. 1.84%±0.17%, t=2.199, P= 0.041). There was no statistical difference regarding the relative expression level of VDR between mild and severe CA16 HFMD(4.16%±1.73% vs. 2.93%±1.73%, t=1.587, P=0.129). Conclusion:Compared with healthy children, the expression level of VDR is significantly lower in children with EV71 HFMD, and may be related to the severity of EV71 HFMD.
