  • Correlation of the T102C Polymorphism of Serum 5-Hydroxytryptamine and Its Receptor Gene and Suicidal Behavior by Poison in Non-depressive Patients

    ObjectiveTo explore the correlation of serum levels of 5-hydroxytryptamine (5-HT) and 5-HT2A receptor gene T102C polymorphism with suicidal behavior by poison in non-depressive patients, in order to diagnose and intervene the suicidal behavior of patients as early as possible. MethodsSixty-two non-depressive patients with the behavior of suicide by poison treated between January 2013 and June 2014 were selected as patient group, and other 66 healthy persons were selected as control group. Peripheral blood in the two groups of patients were collected to test the serum levels of 5-HT with enzyme linked immunosorbent assay, and the 5-HT2A receptor gene T102C polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism. The data were analyzed by SPSS 19.0 statistically. ResultsThe serum level of 5-HT in the patient group was significantly lower than that in the control group (P<0.001), and the frequency of T102C genotype in the patient group was higher than the control group (χ2=5.533, P=0.013). The distribution of genotype was different, and homozygous mutations of CC in the patient group were higher than the control group (χ2=5.648, P=0.017). ConclusionThe serum levels of 5-HT and 5-HT2A receptor gene T102C polymorphism, and the frequency of T102C genotype may be related to suicidal behavior by poison in non-depressive patients.
