Relationship between catecholamine level and gene polymorphism of β1 adrenergic receptor G1165C in children with EV71 infection in hand foot and mouth disease.

Objective: To investigate the relationship between the levels of plasma adrenaline and norepinephrine and gene polymorphism of β1 adrenergic receptor G1165C in children with enterovirus 71 (EV71) infection in hand foot and mouth disease (HFMD).

Methods: The polymerase chain reaction (PCR) was used to detect the expression of gene polymorphism of β1 adrenergic receptor G1165C in vitro. The levels of plasma adrenaline and norepinephrine were measured by enzyme-linked immunosorbent assay (ELISA).
