12019新型冠状病毒基因组特征和流行病学:病毒起源和受体结合的意义显示文摘研究者对来自9例新型冠状病毒肺炎住院患者的支气管肺泡灌洗液样本和培养的分离株进行了下一代测序。从这些个体中获得了严重急性呼吸综合征-冠状病毒2(severe acute respiratory syndrome-coronavirus 2,SARS-CoV-2)的完整和部分基因组序列。利用Sanger测序连接病毒重叠群以获得全长基因组,cDNA末端快速扩增确定终端区。对这些SARSCoV-2基因组和其他冠状病毒基因组进行了系统进化分析,以确定该病毒的进化史并有助于推断其可能的起源。刘青(译) 刘莉(审校) Lu R Zhao X Li J Niu P Yang B Wu H Wang W Song H Huang B Zhu N Bi Y Ma X Zhan F Wang L Hu T Zhou H Hu Z Zhou W Zhao L Chen J Meng Y Wang J Lin Y Yuan J Xie Z Ma J Liu WJ Wang D Xu W Holmes EC Gao GF Wu G Chen W Shi W Tan W 2020中华高血压杂志2020,28,3:516
2术中神经电生理监测在单椎板入路选择性神经后根离断术中的作用显示文摘目的单椎板入路选择性神经后根离断术(SL-SDR)治疗痉挛性脑瘫完全依赖术中神经电生理监测结果。本研究旨在讨论SL-SDR术中肌电图判读对神经根选择和离断的影响及作用。方法回顾分析2016年5月至2019年3月在上海交通大学附属儿童医院神经外科采用改良神经电生理监测离断方案指导下SL-SDR治疗的痉挛性脑瘫患儿的临床资料,重点关注术中肌电图判读及其与术前临床表现的相关性,以及比较采用不同神经电生理监测离断方案解读术中肌电图时的神经后根选择差异。结果共纳入318例患儿,男性231例、女性87例,平均年龄5.9岁,32例为偏瘫、161例为双侧瘫、125例为四肢瘫。每例患儿有2~8组目标肌群(术前肌张力≥2级)。术中神经电生理监测结果显示,探测的21728枚神经小根[(68.3±8.2)枚/例]中6272枚(28.9%)与肛门括约肌相关,15456枚[(48.6±7.6)枚/例]与下肢肌群相关,其中,神经后根11009枚[(34.6±7.4)枚/例]。共有3370枚[(10.6±4.7)枚/例]符合改良神经后根离断方案,其中3061枚50%部分离断、309枚75%部分离断。术前粗大运动功能分级(GMFCS)分级Ⅰ~Ⅴ级的离断率(部分离断的神经后根数/下肢肌群相关神经后根数)分别为15.8%、22.3%、33.4%、41.8%和45.7%。75%部分离断的离断率随术前GMFCS分级的递增而增加,分别为1.5%、4.8%、8.5%、14.1%和15.2%。术后3周,2068组目标肌群肌张力显著降低[(1.7±0.5)级对(2.7±0.6)级]。术前GMFCS分级Ⅰ和Ⅱ级患儿采用传统离断方案约有20%的病例无法识别任何1枚约20%需离断的神经后根,而随着患儿术前GMFCS分级的递增,传统与改良方案离断的符合率逐步提高,分别为39.5%、41.3%、52.2%、54.1%和62.8%。结论由于SL-SDR完全依赖于术中肌电图判读,使得术中神经电生理监测显得至关重要。改良神经电生理监测离断方案指导下的SL-SDR可以安全、有效治疗痉挛性脑瘫。SL-SDR术中肌电图及其与临床表现相关的预后,可以使临床医师更好地理解此类患儿脊髓神经元环路的运作模式。Xiao B Constatntini S Browd SR Zhan Q Jiang W Mei R 詹琪佳(编译) 2020中国现代神经疾病杂志2020,20,4:4
3Effect of Weak Light on the Photoassimilates Distribution and Transformation of Young Grape Plants显示文摘The effect of weak light on the photoassimilates distribution and transformation of young Jingyu grape plants ( Vitis vinefera L. cv. Jingyn) were studied by shading. Compared to the grape grown under natural light intensity environment, the net photosynthetic rate diurnal variation curve of experimental plants grown in weak light intensity environment was remarkably lower. Its leaf and stem biomass ratio increased when light intensity decreased, the root and new shoot biomass ratio showed an opposite trend. The 14C-photoassimilates was mostly distributed to young leaves and stem, a little was distributed to root. The metabolism of 14C-photoassimilates distributed to the entire grape body were also changed under weak light intensity environment.ZHAN Ji-cheng, HUANG Wei-dong and WANG Li-jun(College of Horticultural Sciences , China Agricultural University, Beijing 100094 , P.
