Abstract:
Objective To investigate the expression of serum microRNA(miR)-340-5p,miR-155-5p and their relationship with Th1/Th2 cytokines in patients with chronic hepatitis B.Methods A total of 128 pa-tients with chronic hepatitis B in this hospital from October 2021 to October 2023 were selected as the study group,and 96 healthy subjects from the hospital during the same period were selected as the control group.The expression levels of serum miR-340-5p and miR-155-5p were detected by fluorescence quantitative PCR(qPCR),and the expression levels of serum Th1/Th2 cytokines were detected by enzyme-linked immunosor-bent assay(ELISA).The relationship between miR-340-5p,miR-155-5p and Th1/Th2 cytokines was analyzed by Pearson method,and the influence of serum miR-340-5p and miR-155-5p on the occurrence of chronic HPV infection was analyzed by Logistic regression.Results Compared with the reference group,the serum levels of miR-340-5p,miR-155-5p,IL-4,and IL-13 in the study group decreased(P＜0.05),while the levels of IFN-γand IL-12 increased(P＜0.05).Serum miR-340-5p was negatively correlated with IFN-γ and IL-12(r=-0.315,-0.293,both P＜0.05),and positively correlated with IL-4 and IL-13(r=0.413,0.412,both P＜0.05).Serum miR-155-5p was negatively correlated with IFN-γ and IL-12(r=-0.406,-0.375,both P＜0.05),and positively correlated with IL-4 and IL-13(r=0.343,0.407,both P＜0.05).Serum miR-340-5p(OR=0.735,95％CI:Increased expression levels of 0.590-0.915)and miR-155-5p(OR=0.612,95％CI:0.416-0.900)were protective factors for the occurrence of chronic hepatitis B.IFN-γ(OR=1.652,95％CI:1.170-2.333)and IL-12(OR=1.063,95％CI:1.012-1.116)were risk factors for chronic hepatitis B(P＜0.05).Conclusion Serum miR-340-5p and miR-155-5p are usually low expressed in chronic hepatitis B patients,and they are negatively correlated with Th1 cytokine level and positively correlated with Th2 cytokine level.
