Objectives Microembolic signals(MES)on transcranial Doppler(TCD)predict stroke and cognitive *** levels of total homocysteine(tHcy),a prothrombotic factor,are higher in patients with microemboli in carotid stenosis and in patients with paradoxical *** this study we assessed the association between the level of tHcy and the number of MES in patients with mechanical heart valves(MHVs).Methods TCD monitoring was performed to detect MES before and after breathing 100% oxygen and repeated every 2-4 weeks up to six *** Twenty-five patients with MHVs(mean age:63.60±10.15 years)participated in this study;15 were men(66.47±7.25 years)and 10 were women(59.30±12.60 years).In total,there were 126 study *** multiple regression,higher tHcy was associated with more MES in both preoxygenation(OR 1.34(95%CI 1.07 to 1.68,P=0.009))and postoxygenation(OR 1.40(95% CI 1.07 to 1.83,P=0.01))*** smoking and the length of time between the operation and monitoring also correlated with a higher number of MES before and after breathing oxygen,particularly in *** Higher tHcy and smoking were associated with a higher MES count in both preoxygenation and postoxygenation *** smoking can be stopped and hyperhomocysteinaemia is treatable,these are clinically important findings.

Understanding how plants respond to nitrogen in their environment is crucial for determining how they use it and how the nitrogen use affects other processes related to plant growth and development. Under nitrogen limitation the activity and affinity of uptake systems is increased in roots, and lateral root formation is regulated in order to adapt to low nitrogen levels and scavenge from the soil. Plants in the legume family can form associations with rhizobial nitrogen-fixing bacteria, and this association is tightly regulated by nitrogen levels. The effect of nitrogen on nodulation has been extensively investigated, but the effects of nodulation on plant nitrogen responses remain largely unclear. In this study, we integrated molecular and phenotypic data in the legume Medicago truncatula and determined that genes controlling nitrogen influx are differently expressed depending on whether plants are mock or rhizobia inoculated. We found that a functional autoregulation of nodulation pathway is required for roots to perceive, take up, and mobilize nitrogen as well as for normal root development. Our results together revealed that autoregulation of nodulation, root development, and the location of nitrogen are processes balanced by the whole plant system as part of a resource-partitioning mechanism.

背景:肩关节上盂唇前后部(SLAP),是维持肩关节稳定的重要结构。SLAP的损伤常常造成肩关节的疼痛和功能障碍,但在临床上通过常规查体却很难确诊。目的:验证我们发现的一个新的临床试验用于诊断SLAP损伤。方法:选取因肩关节疼痛初次进行关节镜手术治疗的患者。术前均进行4项常用的SLAP损伤的临床检查法Speed、Yergason、O'Brien、及我们的新试验(Reverse Biceps Load test)进行检查做初步诊断。之后所有患者进行肩关节镜检查,术中镜下对有SLAP损伤的患者进行记录并分型。结果:从2010年2月至2010年8月大约有137名肩关节疼痛的患者进行了肩关节镜手术治疗,其中52名患者存在有SLAP或二头肌长头腱的损伤。其中对于SLAP及二头肌腱的损伤,新试验敏感度76.92%,特异性为43.53%。当肩关节后伸,前部极度外旋时SLAP及二头肌长头腱处于高张力状态。此时轻微的外力就可诱发疼痛,因此新试验具有较高的敏感性,但此位置时前关节囊及部分肩袖亦处于高张力状态,所以特异性会受一定影响。结论:新试验对于SLAP及二头肌腱损伤有较高的敏感性,可以作为SLAP损伤的筛选试验运用于临床。

新冠肺炎大流行是一个对教育,尤其是高等教育的认识进行重新思考的机会。由于这场大流行病所造成的全面危机,尤其是所谓应急远距离教学的开展,各级各类教育工作者不得不重新思考他们的角色、支持学生完成学习任务的方法,以及如何把学生看作是自我组织学习者、积极公民和自主社会能动者。我们发表在本刊的前一篇文章试图总结和分享一些专家的建议,帮助普通高校教师适应在线教与学。作为该文续篇,本文旨在回答以下问题:普通高校教师已经经历了突发、不得不为之的在线教与学,这种经验如何能有助于弥合今后在线与面授教学的距离?受访的四位专家(同时也是本文合作者)一致强调高等教育的教学法理论化而不是数字化,认为战略决策是后新冠大流行时代教育实践的核心。本文回顾过去一年发表的文章,并分析受访专家对研究问题的看法,结果表明,在应急远距离教学过程中“被迫”使用数字技术教学这种情况有可能渐渐变成数字和非数字工具和方法的和谐融合,以促成更加主动、灵活和有意义学习的发生。
