目的:研究不同肌糖原状态下运动诱导肌源性白细胞介素6(Interukin-6,IL-6)表达及蛋白释放与葡萄糖转运体4(Glucose Transport 4,GLUT4)基因表达的关系。方法:通过特定的运动方案和饮食方案造成大鼠在运动前体内肌糖原含量不同,再观察定...目的:研究不同肌糖原状态下运动诱导肌源性白细胞介素6(Interukin-6,IL-6)表达及蛋白释放与葡萄糖转运体4(Glucose Transport 4,GLUT4)基因表达的关系。方法:通过特定的运动方案和饮食方案造成大鼠在运动前体内肌糖原含量不同,再观察定量负荷跑台运动后肌源性IL-6表达及释放与葡萄糖转运体GLUT4基因表达的变化规律。结果:血清IL-6浓度在运动30min后显著增加,运动120min后达到峰值,运动后逐渐降低;骨骼肌IL-6mRNA在运动120min后显著增加,运动后3-6h继续增加至峰值;骨骼肌GLUT4mRNA在运动时并未增加,而在运动后3h开始增加,运动后6h达到峰值。上述三个指标在低肌糖原组的增加与正常糖原组相比更加显著。结论:低肌糖原含量可以促进运动中IL-6的释放及运动后恢复期IL-6和GLUT4的基因表达;运动导致恢复期GLUT4基因表达的增加很有可能与肌源性IL-6的表达及IL-6的自分泌作用有关。展开更多

It further represents an economic burden on society due to the high consumption of healthcare resources and the non-productivity of IBS patients. The diagnosis of IBS is based on symptom assessment and the Rome Ⅲ criteria. A combination of the Rome Ⅲ criteria, a physical examination, blood tests, gastros-copy and colonoscopy with biopsies is believed to be necessary for diagnosis. Duodenal chromogranin A cell density is a promising biomarker for the diagnosis of IBS. The pathogenesis of IBS seems to be multifactorial, with the following factors playing a central role in the pathogenesis of IBS:heritability and genetics, dietary/intestinal microbiota, low-grade inflammation, and disturbances in the neuroendocrine system (NES) of the gut. One hypothesis proposes that the cause of IBS is an altered NES, which would cause abnormal GI motility, secretions and sensation. All of these abnormalities are characteristic of IBS. Alterations in the NES could be the result of one or more of the following:genetic factors, dietary intake, intestinal flora, or lowgrade inflammation. Post-infectious IBS (PI-IBS) and inflammatory bowel disease-associated IBS (IBD-IBS) represent a considerable subset of IBS cases. Patients with PI-and IBD-IBS exhibit low-grade mucosal inflammation, as well as abnormalities in the NES of the gut.展开更多

Odors compounds can act on the neuroendocrine system, neurotransmitters and neuromodulators, influencing psychological behavior as well as body function. The study was conducted in 20 individuals in each test to analyze the effects of essential oil inhalation on psychomotor performance in the healthy volunteers. Two tests were performed in the present study （1） SLCT （six letter cancellation test） and （2） DLST （digit letter substitution test）. These tests were carded out for the assessment of psychopharmacological activity of essential oil of Rosa damascena Mill., in healthy young human individuals belonging to the age group 18 to 22 years. The results of the psychomotor performance test in healthy human individuals revealed that there was improvement in psychomotor functions.展开更多
