Abstract:
Objective:To establish the normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province.Methods:A prospective study was conducted on healthy Han-nationality children aged 3-12 who took physical examination in Wuhan Children′s Hospital, Hubei province from January to August 2021.The children were asked for their medical histories, and those with neurological diseases, psychiatric diseases, infection, trauma, and a drug history in the past 2 weeks were excluded.The plasma of 324 children (262 males, 62 females; 217 cases in the 3-7 years old, 107 cases in the 8-12 years old) and urine of 391 children (302 males, 89 females; 266 cases in the 3-7 years old, 125 cases in the 8-12 years old) were collected.They ultra performance liquid chromatography-mass spectrometry multiple techniques (UPLC-MS/MS) were used to detect 10 kinds of neurotransmitters (e.g., dopamine, epinephrine, glutamic acid, etc.) in plasma and 8 kinds of neurotransmitters (e.g., dopamine, epinephrine, 5-hydroxyindoleacetic acid, etc.) in random urine.The normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province was established.The Kruskal- Wallis H test was made for statistical analysis of the differences in neurotransmitter levels among different age groups and gender groups.The neurotransmitter levels between different groups were compared by the Nemenyi test. Results:There were no significant differences in the levels of various neurotransmitters in children of different genders(all P>0.05). There were significant differences in the levels of dopamine, methoxy-norepinephrine, tryptophan and γ-aminobutyric acid in the plasma of children aged 3-7 years and 8-12 years.There were significant differences in the levels of dopamine, epinephrine, norepinephrine, methoxy-norepinephrine, high vanillic acid and 5-hydroxyindoleacetic acid in the random urine between the 3-7 years old group and the 8-12 years old group. Conclusions:The normal reference range of neurotransmitters in Han-nationality children aged 3-12 in Hubei province is established.This study provides reference for clinical practice and lays a foundation for the study of neurotransmitter-related diseases in children.
