ABSTRACT
Objective@# To investigate the relationship between serum miR-199a-5p and miR-378a-3p levels and the recurrence of infants with proliferative facial hemangioma relapsed after propranolol withdrawal in infants.@*Methods@#Ninety-three infants with proliferative facial hemangioma were selected, all of whom received propranolol treatment. The recurrence of the hemangioma after treatment was followed up, and the children were divided into a recurrence group (23 patients) and a nonrecurrence group (70 patients). Venous blood was collected before and after treatment, and the serum levels of miR-199a-5p and miR-378a-3p were detected by qRT-PCR, and the relationship between the serum levels of miR-199a-5p and miR-378a-3p and the recurrence of proliferative facial hemangioma relapsed after propranolol withdrawal in infants was analyzed.@*Results @# The serum expressions levels of miR-199a-5p and miR-378a-3p in non-relapsed group were increased after treatment compared with before treatment (P < 0.05), and there was no significant difference in the levels of miR-199a-5p and miR-378a-3p in the serum of the recurrence group after treatment compared with before treatment (P > 0.05). After treatment, the levels of miR-199a-5p and miR-378a-3p in the serum of the recurrence group were lower than those of the nonrecurrence group (P < 0.05). After treatment, the serum levels of miR-199a-5p and miR-378a-3p in patients with Ⅲ ~Ⅳ Norm grade hemangioma were higher than those in patients with Ⅰ~Ⅱ Norm grade hemangioma (P < 0.05). Logistic regression analysis showed that the low expression of miR-199a-5p, low expression of miR-378a-3p and tumor grade Ⅰ~Ⅱ after treatment were risk factors for the recurrence of proliferative facial hemangioma after propranolol withdrawal in infants (P < 0.05).@*Conclusion@# Low serum levels of miR-199a-5p and miR-378a-3p are associated with the recurrence of proliferative facial hemangioma after propranolol withdrawal in infants.
