慢性疲劳综合症的神经内分泌免疫研究进展   总被引:1,自引:0,他引:1  
慢性疲劳综合症是现代医学新认识的疾病,发病机制复杂.最近研究发现,细胞免疫功能和细胞因子表达的异常、内分泌功能的紊乱以及神经系统功能的异常可能参与该病的病理机制,因此神经内分泌免疫系统的失调是引发慢性疲劳综合症的重要因素.  相似文献

Fetal alcohol spectrum disorder (FASD ) is a prevalent neurodevelopmental disability with significant implications for learning and behaviour. International research suggests that the prevalence of FASD in school‐aged children is 2.3–6.3%. In this paper, we address the questions: (1) what is FASD ; (2) what is the prevalence of FASD in schools; (3) what is the impact of FASD ; and (4) why develop special FASD education strategies and programmes? We summarise the 18‐year history of W innipeg S chool D ivision's development of its FASD P rogramme of services, describe the specialised FASD classrooms and then present the results from a consensus‐generating workshop comprised of 36 FASD education professionals, with over 209 years of collective FASD education programme experience, who were asked to identify and reach consensus on best strategies and lessons learned in FASD education programmes. We then suggest that effectively educating children with FASD is critical to get right if positive educational outcomes are to be realised.  相似文献

Two studies investigating the relationship betweenphoneme awareness and word reading ability in Downsyndrome (DS) are reported. The first study included33 Brazilian individuals with DS (mean age = 23years). They all had begun to read and all showedclear signs of phonological recoding skills. Thirty-three normal children (mean age = 7 years),matched with the individuals with DS for readingability, participated as controls. The second studyincluded individuals with DS with a wider range ofreading ability: a group of 46 readers (mean age = 22years) and a group of 47 nonreaders (mean age = 18years). The results question Cossu, Rossini, andMarshall's (1993a) claim that phoneme awareness is notrelated to alphabetic reading acquisition in DS.Although the individuals with DS who participated inthe first study performed rather poorly on a task thatpresupposes the ability to explicitly manipulatephonological representations, they performed quitewell on a task assessing the ability to detectphonemic similarities in words. We suggest that it wasthis ability that enabled them to acquire phonologicalrecoding skills as well as they did, despite theircognitive limitations. The results of the second studywere consistent with this interpretation. The abilityto detect phonemic similarities in wordssignificantly differentiated between the readers andthe nonreaders, even after we controlled forvariations in letter knowledge, intelligence, andchronological age.  相似文献

试验研究了猪繁殖与呼吸综合征病毒(PRRSV)弱毒疫苗鼻腔接种对母猪子宫黏膜内淋巴细胞分布的影响.试验选用4月龄长白×大约克夏二元杂交母猪12头.结果表明:鼻腔接种可使猪子宫角、体和颈黏膜上皮内淋巴细胞的数量较对照组增加,差异显著(P<0.01).经鼻腔接种时,子宫黏膜固有层中多见淋巴细胞聚集成群,并向黏膜腔表面排放.说明PRRSV弱毒疫苗鼻腔接种对母猪子宫黏膜及上皮内淋巴细胞的分布具有显著影响.  相似文献

We investigated the associations of cardiometabolic risk factors with academic achievement and whether motor performance, cardiorespiratory fitness, physical activity, or sedentary behaviour mediated these associations. Altogether 175 children 6–8 years-of-age participated in the study. We assessed body fat percentage (BF%), waist circumference, insulin, glucose, triglycerides, HDL cholesterol, and systolic and diastolic blood pressure, leptin, alanine aminotransferase, and gamma-glutamyltransferase (GGT). Reading fluency, reading comprehension, and arithmetic skills were assessed using standardized tests. Speed/agility, balance, and manual dexterity test results were used to calculate motor performance score and physical activity was assessed by combined heart rate and movement sensor and cardiorespiratory fitness by maximal cycle ergometer test. In boys, BF% was inversely associated with reading fluency (β = ?0.262, P = 0.007) and reading comprehension (β = ?0.216, P = 0.025). Motor performance mediated these associations. Leptin was inversely related to reading fluency (β = ?0.272, P = 0.006) and reading comprehension (β = ?0.287, P = 0.003). The inverse association of leptin with reading fluency was mediated by motor performance. In girls, GGT was inversely associated with reading fluency independent of confounders (β = ?0.325, P = 0.007). The inverse association of BF% with academic achievement among boys was largely explained by motor performance. Leptin in boys and GGT in girls were inversely associated with academic achievement independent of confounding factors.  相似文献
