The strategy of physiological arousal of athletes in sports competition based on drug intervention / A estratégia da excitação fisiológica de atletas em competições esportivas com base em intervenção medicamentosa / Deportistas basados en intervenciones farmacéuticas, estrategia fisiológica de despertar

ABSTRACT Generally speaking, the physiological index of the human body is in a relatively stable state, which refers to the function of various organ systems with the characteristics of high-tide period, low-tide period and critical period. However, for competitive athletes, it is necessary to maintain physiological activation in both training and competition. In view of this, this study will analyze the physiological arousal degree of aspirin and acetaminophen in order to provide a reference for athletes to take analgesic drugs. In this study, the analytic hierarchy process (AHP), principal component analysis and factor analysis, were used to construct a scientific evaluation system of physiological arousal level, and the medication and non-medication status of 90 athletes were evaluated. The results showed that aspirin was better than acetaminophen in blood urea and serum creatine kinase, and the comprehensive score of some athletes was higher than 0.95. Aspirin is better in arousing athletes' physiology. The research results will provide scientific guidance for athletes to take antipyretic and analgesic drugs.

RESUMO Em termos gerais, o índice fisiológico do corpo humano encontra-se num estado relativamente estável, que se refere à função de vários sistemas de órgãos no corpo humano, com as características do período de altas, período de baixas e período crítico. No entanto, para atletas competitivos, é necessário manter a ativação fisiológica em treinamento e competição. Em vista disso, este estudo irá analisar o grau fisiológico de excitação de aspirina e acetaminofeno, a fim de fornecer referência para os atletas a tomar medicamentos analgésicos. Neste estudo, o Analytic Hierarchy Process (AHP), análise de componentes principal e análise de fatores foram usados para construir um sistema de avaliação científica de nível de excitação fisiológica, e o estado de medicação e de não medicação de 90 atletas foram avaliados. Os resultados mostraram que a aspirina foi melhor do que o acetaminofeno na ureia sanguínea e na creatina quinase sérica, e o escore abrangente de alguns atletas foi maior do que 0.95. A aspirina é melhor no despertar da fisiologia dos atletas. Os resultados da pesquisa fornecerão orientação científica para os atletas tomarem medicamentos antipiréticos e analgésicos.

Methylation in the promoter regions of WT1, NKX6-1 and DBC1 genes in cervical cancer tissues of Uygur women in Xinjiang

Abstract This study aimed to explore: 1) DNA methylation in the promoter regions of Wilms tumor gene 1 (WT1), NK6 transcription factor related locus 1 gene (NKX6-1) and Deleted in bladder cancer 1 (DBC1) gene in cervical cancer tissues of Uygur women in Xinjiang, and 2) the correlation of gene methylation with the infection of HPV16/18 viruses. We detected HPV16/18 infection in 43 normal cervical tissues, 30 cervical intraepithelial neoplasia lesions (CIN) and 48 cervical cancer tissues with polymerase chain reaction (PCR) method. Methylation in the promoter regions of the WT1, NKX6-1 and DBC1 genes in the above-mentioned tissues was measured by methylation-specific PCR (MSP) and cloning sequencing. The expression level of these three genes was measured by real-time PCR (qPCR) in 10 methylation-positive cervical cancer tissues and 10 methylation-negative normal cervical tissues. We found that the infection of HPV16 in normal cervical tissues, CIN and cervical cancer tissues was 14.0, 36.7 and 66.7%, respectively. The infection of HPV18 was 0, 6.7 and 10.4%, respectively. The methylation rates of WT1, NKX6-1 and DBC1 genes were 7.0, 11.6 and 23.3% in normal cervical tissues, 36.7, 46.7 and 30.0% in CIN tissues, and 89.6, 77.1 and 85.4% in cervical cancer tissues. Furthermore, WT1, NKX6-1 and DBC1 genes were hypermethylated in the high-grade squamous intraepithelial lesion (CIN2, CIN3) and in the cervical cancer tissues with infection of HPV16/18 (both P< 0.05). The expression of WT1, NKX6-1 and DBC1 was significantly lower in the methylation-positive cervical cancer tissues than in methylation-negative normal cervical tissues. Our findings indicated that methylation in the promoter regions of WT1, NKX6-1 and DBC1 is correlated with cervical cancer tumorigenesis in Uygur women. The infection of HPV16/18 might be correlated with methylation in these genes. Gene inactivation caused by methylation might be related to the incidence and development of cervical cancer.
