1Blue light is more essential than red light for maintaining the activities of photosystem Ⅱ and Ⅰ and photosynthetic electron transport capacity in cucumber leaves显示文摘Blue and red lights differently regulate leaf photosynthesis. Previous studies indicated that plants under blue light generally exhibit better photosynthetic characteristics than those under red light. However, the regulation mechanism of related photosynthesis characteristics remains largely unclear. Here, four light qualities treatments(300 μmol m–2 s–1) including white fluorescent light(FL), blue monochromatic light(B, 440 nm), red monochromatic light(R, 660 nm), and a combination of red and blue light(RB, R:B=8:1) were carried out to investigate their effects on the activity of photosystem II(PSII) and photosystem I(PSI), and photosynthetic electron transport capacity in the leaves of cucumber(Cucumis sativus L.) seedlings. The results showed that compared to the FL treatment, the R treatment significantly limited electron transport rate in PSII(ETRII) and in PSI(ETRI) by 79.4 and 66.3%, respectively, increased non-light induced non-photochemical quenching in PSII(ΦNO) and limitation of donor side in PSI(ΦND) and reduced most JIP-test parameters, suggesting that the R treatment induced suboptimal activity of photosystems and inhibited electron transport from PSII donor side up to PSI. However, these suppressions were effectively alleviated by blue light addition(RB). Compared with the R treatment, the RB treatment significantly increased ETRII and ETRI by 176.9 and 127.0%, respectively, promoted photosystems activity and enhanced linear electron transport by elevating electron transport from QA to PSI. The B treatment plants exhibited normal photosystems activity and photosynthetic electron transport capacity similar to that of the FL treatment. It was concluded that blue light is more essential than red light for normal photosynthesis by mediating photosystems activity and photosynthetic electron transport capacity.MIAO Yan-xiu W ANG Xiao-zhuo G AO Li-hong C HEN Qing-yun QU Mei 2016Journal of Integrative Agriculture2016,15,1:9

3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
