酪氨酸羥化酶基因SNP多態(tài)性與運(yùn)動性失眠的實(shí)驗(yàn)研究
[Abstract]:Exercise insomnia is a special type of insomnia and one of the symptoms of exercise fatigue. Moderate exercise helps sleep, but beyond a certain limit can lead to insomnia, or exercise insomnia. As to whether insomnia is hereditary or not, some researchers have investigated and confirmed the heredity of insomnia. Catecholamine is an important hormone and neurotransmitter in the human body, which is synthesized by tyrosine and involved in the synthesis of four enzymes. Tyrosine hydroxylase (tyrosine hydroxylase) is the first enzyme to catalyze tyrosine to produce dopa, which plays an important role in regulating the function of central nervous system and sympathetic nervous system, because of the important role of TH in regulating central nervous system. In this study, TH gene level was used to study the occurrence of motor insomnia. Objective: to analyze the statistical difference of tyrosine hydroxylase gene SNP genotyping between insomnia group and non-insomnia group by questionnaire investigation and PCR sequencing, and to explore whether there is a certain correlation between tyrosine hydroxylase gene polymorphism and motor insomnia. Methods: the basketball class, martial arts class, aerobics class, weightlifting class, track and field class, basketball team, martial arts team, calisthenics team, weightlifting team, and weightlifting team were investigated by questionnaire in Department of physical Education of Chengdu Institute of physical Education. Three hundred and thirty athletes of track and field team investigated their subjective feelings, analyzed and judged according to the evaluation criteria of motor insomnia, divided them into insomnia group and non-insomnia group, and used polymerase chain reaction-restriction fragment length polymorphism (PcR-RFLP) analysis method. The tyrosine hydroxylase gene sequences of 16 patients with insomnia and 18 patients with no insomnia were obtained by sequencing. By comparing the SNP polymorphism of tyrosine hydroxylase gene between insomnia group and non-insomnia group, the relationship between tyrosine hydroxylase gene and motor insomnia was determined. Results: 1, the athletes' fatigue conscious symptoms were measured, of which 67% of the athletes scored in the fourth grade (19-24 points). 2, basketball, martial arts, aerobics, weightlifting, 100% of weightlifters developed physical fatigue, 20% viscera fatigue, 9% mental fatigue, basketball, martial arts, calisthenics, The probability of mental fatigue in track and field were as follows: 60: 52and 50: 360.The tyrosine hydroxylase gene locus G-494AnC-388TFA-641G was analyzed from the experimental data. There was statistical difference between the exercise insomnia group and the non-insomnia group, but there was no statistical difference between the G-94 TA- 581GT-741GT-801C741 G-814AHN C-824T and C-833T loci. Conclusion: 1. After training, 67% of athletes will develop middle and higher degree fatigue. 2. Weight lifters have higher body fatigue rate, and lower ratio of viscera fatigue and mental fatigue. Athletes in basketball, martial arts, aerobics and track and field events have higher rates of viscera fatigue and mental fatigue. 3. The polymorphism of tyrosine hydroxylase gene locus G-494AnC-388TKA-641G is associated with the occurrence of sports insomnia. However, because the sample size was large and small, the tyrosine hydroxylase gene locus G-494An C-388TKA-641G could not be proved to be related to motor insomnia. At the same time, 7 loci of tyrosine hydroxylase gene G-94 TX A-581GFT-741CU G-801CU G-814ANC-824T and C-833T did not show any correlation with motor insomnia in this study.
