Brain-derived neurotrophic factor is a crucial neurotrophic factor that plays a significant role in brain health. Although the vast majority of meta-analyses have confirmed that exercise interventions can increase brain-derived neurotrophic factor levels in children and adolescents, the effects of specific types of exercise on brain-derived neurotrophic factor levels are still controversial. To address this issue, we used meta-analytic methods to quantitatively evaluate, analyze, and integrate relevant studies. Our goals were to formulate general conclusions regarding the use of exercise interventions, explore the physiological mechanisms by which exercise improves brain health and cognitive ability in children and adolescents, and provide a reliable foundation for follow-up research. We used the Pub Med, Web of Science, Science Direct, Springer, Wiley Online Library, Weipu, Wanfang, and China National Knowledge Infrastructure databases to search for randomized controlled trials examining the influences of exercise interventions on brain-derived neurotrophic factor levels in children and adolescents. The extracted data were analyzed using Review Manager 5.3. According to the inclusion criteria, we assessed randomized controlled trials in which the samples were mainly children and adolescents, and the outcome indicators were measured before and after the intervention. We excluded animal experiments, studies that lacked a control group, and those that did not report quantitative results. The mean difference(MD;before versus after intervention) was used to evaluate the effect of exercise on brain-derived neurotrophic factor levels in children and adolescents. Overall, 531 participants(60 children and 471 adolescents, 10.9–16.1 years) were included from 13 randomized controlled trials. Heterogeneity was evaluated using the Q statistic and I^(2) test provided by Review Manager software. The meta-analysis showed that there was no heterogeneity among the studies(P = 0.67,

近年来,水利水电工程中暴发了沼蛤(淡水壳菜)污损问题,不同程度地影响了水利和水电工程的输水、生产等安全,引起了国内外社会广泛关注。本文研究结果显示,沼蛤在长江流域主要分布于四川及以下的低海拔区,四川以上高海拔区未见记录;基于COI和ITS 1基因联合构建的系统发育树分析显示,长江流域沼蛤可能存在两个类群,其中COI序列A+T含量(64.7%)显著高于C+G含量(35.3%),种内遗传距离范围为0~0.123;COI序列总单倍型多样性指数为0.893,核苷酸多样性指数为0.069;ITS 1序列A+T含量为45.3%,C+G含量为54.7%,种内遗传距离范围为0~0.061;ITS 1序列总单倍型多样性指数为0.679,核苷酸多样性指数为0.028。基于COI基因分析的两个亲缘关系类群间的遗传分化系数为0.844,基因差异分化系数为0.118;基于ITS 1基因分析的相应参数分别为0.927和0.492。基于形态学特征分析显示,长江流域沼蛤的长高比、长宽比和韧带长度差异显著,可明显分成两个类群,且与COI和ITS 1基因分析显示的两个类群相对应。基于栖息生境分析显示,长江流域沼蛤类群1主要生活在水流较缓、底质以卵石为主的区域,表现为缓流型;类群2主要生活在水流较急、底质以泥沙为主的区域,表现为激流型,对环境的适应性更强,分布范围较类群1更广,在传播扩散能力方面表现更强。本研究有助于了解长江流域沼蛤基础生物学信息,可为流域沼蛤的综合防控提供重要参考。
