简介:摘要ObjectiveThis single-center study aimed to investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on modulation of thyroid hormone levels and cognition in the recovery stage of patients with cognitive dysfunction following stroke.MethodsSeventy post-stroke patients who had cognitive impairment were randomly assigned to either the rTMS group or the control (sham) group. Both groups were administered basic treatment, with the rTMS group receiving rTMS (1 Hz, 90% MT, 1000 pulse/20 min, once a day for 5 days, for a total of 20 times), the stimulation site was the contralateral dorsolateral prefrontal cortex (DLPFC), and the sham group receiving sham stimulation which had the same stimulation parameters and site, except that the coil plane was placed perpendicular to the surface of the scalp. Cognitive function assessment and thyroid function tests were performed before and after 4 weeks of treatment.Resultserum levels of triiodothyronine (T3), free triiodothyronine (FT3), and thyroid stimulating hormone (TSH) showed a positive correlation with Montreal Cognitive Assessment (MoCA) scale score of stroke patients in the recovery phase. The post-treatment change in the scores of MoCA and Modified Barthel Index (MBI) and scores of 3 cognitive domains (visuospatial function, memory, and attention), as well as serum T3, FT3, and TSH levels, were improved more significantly in the rTMS group, and T3 and FT3 levels significantly affected the MoCA scores within the reference range.ConclusionsSerum T3, FT3, and TSH levels of stroke patients in the recovery phase were positively correlated with MoCA score. rTMS increased T3, FT3, and TSH levels and also improved MoCA and MBI of patients in the recovery phase of stroke.

简介:碳排出物由于与经济开发联系的人的精力消费正在增加的数据表演。作为结果,很多注意集中于在碳排出物减少这生长以及提出政策到地址并且减轻气候变化的努力。尽管以前的研究的多数探索了位于中国碳排出物下面的驱动力,很少被执行了在因为相关精力消费统计的有限可获得性城市级。这里,我们利用空间自相关,Markov链过渡矩阵,一个动态面板模型,和系统概括了距离评价(Sys-GMM)以经验为主地评估碳排出物的关键决定因素在基于在1992和2013之间收集的中国遥感数据城市级。我们也使用这些数据讨论考虑的观察空间溢出效果空间与时间落后并且不同地理、经济的weighting矩阵的一个范围。这研究的结果建议在城市级的碳排出物的地区性的差异随着时间的过去减少了,它与显著空间溢出效果,和俱乐部凝块一致高排放。这些模式的进化也显示出明显的路径依赖,当面板数据分析的结果揭示在碳排出物和人均的GDP之间的一种重要U字形的关系的存在时。数据也证明人均的碳排出物在大多数与经济生长在音乐会增加了城市,和那一生长也施加了的第二等的工业和广泛的投资高比例越过中国的城市级的碳排出物上的重要积极效果。相反,道路的快速的人口凝块,在技术的改进,增加的贸易坦诚,和可接近性和密度都在禁止碳排出物起了一个作用。因此,以便减少排出物,当同时行动鼓励减轻这个过程的那些时,中国政府应该立法禁止支持碳的版本的因素的效果。根据在这研究介绍的分析,我们说服那优化工业结构,优化广泛的投资,增加技术的水平,并且改进道路可接近性都是有效途径越过中国增加精力积蓄和还原剂碳排出物。
