2化疗药物诱发神经病理性疼痛的新机制——白介素-17显示文摘化疗药物诱导的外周神经病理性疼痛(CIPN)是癌症治疗常见的不良反应,比例高达80%。CIPN降低病人的生活质量,导致化疗延迟甚至终止,造成化疗效应的降低。白介素-17(IL-17)是目前已发现的30余种白细胞介素之一,按序号排在第17位。本文目的在于探讨脊髓和背根神经节(DRG)的IL-17如何调控CIPN。结果:①在正常小鼠,脊髓背角IL-17主要由星形胶质细胞合成。外源性给予IL-17,增加IIo层Somatostatin阳性(SOM+)-tdTomato神经元的兴奋性突触后电流(sEPSCs)频率,抑制IIo层SOM+神经元的抑制性突触后电流(sIPSCs)频率和幅度。Luo H 刘风雨(译) 2019中国疼痛医学杂志2019,25,12:14
3Transcriptomic landscape regulated by the 14 types of bone morphogenetic proteins(BMPs)in lineage commitment and differentiation of mesenchymal stem cells(MSCs)显示文摘Mesenchymal stem cells(MSCs)are ubiquitously-existing multipotent progenitors that can self-renew and differentiate into multiple lineages including osteocytes,chondrocytes,adipocytes,tenocytes and myocytes.MSCs represent one of the most commonly-used adult progenitors and serve as excellent progenitor cell models for investigating lineagespecific differentiation regulated by various cellular signaling pathways,such as bone morphogenetic proteins(BMPs).As members of TGFb superfamily,BMPs play diverse and important roles in development and adult tissues.At least 14 BMPs have been identified in mammals.Different BMPs exert distinct but overlapping biological functions.Through a comprehensive analysis of 14 BMPs in MSCs,we demonstrated that BMP9 is one of the most potent BMPs in inducing osteogenic differentiation of MSCs.Nonetheless,a global mechanistic view of BMP signaling in regulating the proliferation and differentiation of MSCs remains to be fully elucidated.Here,we conducted a comprehensive transcriptomic profiling in the MSCs stimulated by 14 types of BMPs.Hierarchical clustering analysis classifies 14 BMPs into three subclusters:an osteo/chondrogenic/adipogenic cluster,a tenogenic cluster,and BMP3 cluster.We also demonstrate that six BMPs(e.g.,BMP2,BMP3,BMP4,BMP7,BMP8,and BMP9)can induce ISmads effectively,while BMP2,BMP3,BMP4,BMP7,and BMP11 up-regulate Smad-independent MAP kinase pathway.Furthermore,we show that many BMPs can upregulate the expression of the signal mediators of Wnt,Notch and PI3K/AKT/mTOR pathways.While the reported transcriptomic changes need to be further validated,our expression profiling represents the first-of-its-kind to interrogate a comprehensive transcriptomic landscape regulated by the 14 types of BMPs in MSCs.Linghuan Zhang Qing Luo Yi Shu Zongyue Zeng Bo Huang Yixiao Feng Bo Zhang Xi Wang Yan Lei Zhenyu Ye Ling Zhao Daigui Cao Lijuan Yang Xian Chen Bin Liu William Wagstaff Russell R*Reid Hue H*Luu Rex C*Haydon Michael J*Lee Jennifer Moriatis Wolf Zhou Fu Tong-Chuan He Quan Kang 2019Genes & Diseases2019,6,3:11

5肠系膜下动脉根部淋巴结清扫联合血管低位或高位结扎治疗直肠癌的效果观察显示文摘目的:在结直肠癌手术中,与肠系膜下动脉高位结扎相比,保留左结肠动脉的低位结扎在淋巴结清扫、吻合口漏和肿瘤学结果方面仍存在争议。本研究通过回顾性病例分析探讨腹腔镜直肠癌前切除术中肠系膜下动脉高位结扎或低位结扎对患者近期和远期疗效的影响。方法:回顾性分析2013年至2016年在仁济医院行腹腔镜直肠癌前切除术的614例患者的临床资料,比较低位结扎组和高位结扎组的临床人口学特征、手术时间、IMA根部淋巴结清扫数目、围手术期并发症、术后3年和术后5年的总生存率和无病生存率。两组之间比较采用t检验或χ^(2)检验,生存率采用Kaplan-Meier生存曲线以及Log-rank检验分析。以P<0.05为差异有统计学意义。孙凌宇 俞旻皓 骆洋 LUO Y YU M H HUANG Y Z 2021结直肠肛门外科2021,27,4:6
6Mid-infrared dual-comb spectroscopy with electro-optic modulators显示文摘Absorption spectroscopy of fundamental ro-vibrational transitions in the mid-infrared region provides a powerful tool for studying the structure and dynamics of molecules in the gas phase and for sensitive and quantitative gas sensing.Laser frequency combs permit novel approaches to perform broadband molecular spectroscopy.Multiplex dual-comb spectroscopy without moving parts can achieve particularly high speed,sensitivity and resolution.However,achieving Doppler-limited resolution in the mid-infrared still requires overcoming instrumental challenges.Here we demonstrate a new approach based on difference-frequency generation of frequency-agile near-infrared frequency combs that are produced using electro-optic modulators.The combs have a remarkably flat intensity distribution,and their positions and line spacings can be freely selected by simply dialing a knob.Using the proposed technique,we record,in the 3-μm region,Doppler-limited absorption spectra with resolved comb lines within milliseconds,and precise molecular line parameters are retrieved.Our technique holds promise for fast and sensitive time-resolved studies of,for example,trace gases.Ming Yan Pei-Ling Luo Kana Iwakuni Guy Millot Theodor W Hänsch Nathalie Picqué 2017Light(Science & Applications)2017,6,1:5
7Prevalence of amblyopia among preschool children in central south China显示文摘AIM: To determine the prevalence and factors associated with amblyopia among children aged 30-83 mo in central south of China.METHODS: A population-based, cross-sectional study was conducted in children aged 30-83 mo in Changsha(an urban city) and Zhangjiajie(a rural area) in central south of China. Clinical examinations including ocular alignment, ocular motility, visual acuity(VA), prism cover test, cycloplegic refraction, slit lamp examination and fundus examination were performed by trained study ophthalmologists and optometrists. Unilateral amblyopia was defined as a 2-line difference between eyes with VA<20/32 in the worse eye and with coexisting anisometropia [≥1.00 D spherical eutivalent(SE) for hyperopia, ≥3.00 D SE for myopia, and ≥1.50 D for astigmatism], strabismus, or past or present visual axis obstruction. Bilateral amblyopia was defined as VA in both eyes <20/40(≥ 48-month-old) and <20/50(< 48-month-old), with coexisting hyperopia ≥4.00 D SE, myopia ≤-6.00 D SE, and astigmatism ≥2.50 D, or past or present visual axis obstruction.RESULTS: There were 8042 children enrolled and 7713 children were screened. The amblyopia prevalence in children aged 30-83 mo was 1.09%(95% confidence interval, 0.86%-1.35%) with no age(P=0.81), gender(P=0.46) or area distribution(P=0.93) differences. Of these, 0.68% were unilateral cases and 0.41% were bilateral cases. Underlying causes included anisometropia(40%), binocular refractive error(36%), strabismus(14%) and deprivation(10%). Hyperopia combined with astigmatism was the frequent refractive error for ametropic and anisometropic amblyopia.CONCLUSION: In this rural and urban Chinese population, 1.09% of children with 30-83 mo of age had amblyopia, a prevalence rate similar to that of many other studies. Anisometropia and refractive error are the most common causes of unilateral and bilateral amblyopia respectively.Yun-Ping Li Meng-Wen Zhou Susan H Forster Si-Ying Chen Xin Qi Hui-Ming Zhang Jing Luo 2019International Journal of Ophthalmology(English edition)2019,12,5:5

12Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2.Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q 2006Journal of Semiconductors2006,27,4:2

14纳米光子结构软膜紫外光固化纳米压印(英文)显示文摘紫外光固化纳米压印是实现纳米结构批量复制的一种新技术.其特点是低成本和高分辨,而且可以达到极高的套刻精度.为了得到大面积图案的均匀复制,可用聚二甲基硅氧烷(PDMS)制备透光的压印软模板.其母版图案可由高分辨率电子束曝光和反应离子刻蚀的方法在硅片基底上获得,然后用浇注的方法将图案转移到PDMS上.本实验特别发展了紫外光固化纳米压印适用于软膜压印的双层膜图型转移技术.该双层膜由廉价的光胶和聚甲基丙烯酸甲脂(PMMA)构成.对光胶层的压印可用普通的光学曝光仪实现.然后再将图案用反应离子刻蚀的方法转移到PMMA层中.为了证明方案的可行性,在两种不同材料的半导体基片上压印了三角晶格的光子晶体和准晶结构的图案,并用剥离的方法将它们转移到金属薄膜上,最后成功地进行了硅片刻蚀实验.相信这一纳米制做方法对大面积纳米光子结构和光学集成芯片的制造是普遍适用的.SHI J WANG Z M BAO K PEROZ C BELOTTI M XU L P LUO C X SUN M H ZHANG B JI H OUYANG Q CHEN Y 2006纳米技术与精密工程2006,4,3:2
