Electromagnetic interference (EMI) shielding inhigh-frequency range, especially the rapidly growing terahertz(THz) frequency range, attracts increasing attention due tothe potential application of terahertz in 6G wirelesscommunication, and security inspection. However, traditionalconductive EMI films typically achieve high shieldingeffectiveness through strong reflection, which may causesecondary pollution to other devices. Here, a gradientstructure strategy was proposed to constructTi_(3)C_(2)Tx/hydroxypropyl methyl cellulose (HPMC) film, in whichthe content of Ti_(3)C_(2)Tx gradually increases along the thicknessdirection, resulting in different conductivity of the two surfaces(surface-M and surface-H) for the film. The obtained gradientfilmexhibits an EMI shielding efficiency of over 48.5 dB in theTHz range (0.2-1.6 THz) at a thickness of 40 μm. Especially,as the THz waves incident from the surface-H to the film, the absorption effectiveness reaches 48.2 dB (average absorbedpower loss up to 91.4%), and the reflection effectiveness is only 0.3 dB. In additions, the gradient-film also demonstrates ahigh absorption rate of 95.5% in the infrared band (2.5-16.7 μm). Moreover, the gradient-film exhibits an excellent tensilestress and Young’s modulus value of 173.1 MPa and 2.8 GPa, respectively. Therefore, the gradient-film proposed in thiswork, with excellent electromagnetic absorption in both THz and infrared band, provides a promising candidate for the nextgenerationEMI shielding applications.

During the boreal summer,intraseasonal oscillations exhibit significant interannual variations in intensity over two key regions:the central-western equatorial Pacific(5°S-5°N,150°E-150°W)and the subtropical Northwestern Pacific(10°-20°N,130°E-175°W).The former is well-documented and considered to be influenced by the ENSO,while the latter has received comparatively less attention and is likely influenced by the Pacific Meridional Mode(PMM),as suggested by partial correlation analysis *** elucidate the physical processes responsible for the enhanced(weakened)intraseasonal convection over the subtropical northwestern Pacific during warm(cold)PMM years,the authors employed a moisture budget *** findings reveal that during warm PMM years,there is an increase in summer-mean moisture over the subtropical northwestern *** increase interacts with intensified vertical motion perturbations in the region,leading to greater vertical moisture advection in the lower troposphere and consequently resulting in convective *** a process is pivotal in amplifying intraseasonal convection *** observational findings were further verified by model experiments forced by PMM-like sea surface temperature patterns.

背景:毛囊体外重建依赖于毛乳头细胞及角质形成细胞3D共培养时的自组装行为,该过程与毛囊胚胎发育极为相似,因此,毛囊类器官可作为毛囊再生相关基础研究良好的体外模型,目前,通过仿生系统培养的全人源毛囊类器官已能成功移植到动物体内。毛囊类器官研究使毛囊再生成为可能,但构建方法亦无统一定论,仍面临诸多挑战。目的:综述目前毛囊类器官的研究进展,总结毛囊类器官培养方法及表征,阐述应用前景,为后续研究提供可靠依据,以期促进其在组织工程及脱发治疗的临床转化。方法:应用计算机在中国知网(CNKI)及PubMed数据库中,以“毛囊再生,毛发再生,类器官”为中文检索词,“hair growth,hair loss,hair regeneration,hair follicle,dermal papilla cell,organoid”为英文检索词进行检索,查阅国内外关于毛囊类器官的相关文献,共纳入文献67篇进行后续分析。结果与结论:①不同来源的毛乳头细胞与角质形成细胞可在体外构建毛囊类器官,以获得鼠源、人-鼠嵌合及人源毛囊类器官,并成功用于啮齿动物移植模型;②多种重编程方法如电刺激、添加重组蛋白、解离细胞基因过表达等可用于促进毛囊类器官毛胚形成及毛钉伸长,同时,多种3D打印技术的应用已实现大小可控毛囊类器官的批量生产,极大提高了生产效率;③在解离细胞共培养体系中加入黑素细胞时,或可破译新生毛囊的色素缺失难题,而加入人脐静脉血管内皮细胞时,细胞聚集体内的新生血管可改善营养供给,减少中心部位坏死;④随着工程化类毛囊技术逐渐趋于成熟,患者自体细胞构建的毛囊类器官或可用于严重脱发的个体化医疗。

目的探讨非瓣膜病性心房纤颤(房颤)及其合并脑栓塞患者的抗凝治疗情况。方法采集2012年1月~2013年12月于苏州大学附属第二医院治疗的208例心源性脑栓塞患者的临床资料,对其中存活的164例非瓣膜病性房颤(包括华法林抗凝治疗34例,抗血小板治疗130例)以及另行采集的36例一级预防华法林抗凝治疗的非瓣膜病性房颤患者随访1年。分析70例华法林抗凝治疗患者的基本情况,并依据预防等级、年龄、国际标准化比值(INR)控制水平、1年内是否继发出血进行分组比较,并分析与稳态时华法林剂量相关的因素。结果 164例非瓣膜病性房颤合并脑栓塞患者中,华法林抗凝组患者年龄、入院NIHSS评分明显低于抗血小板组,INR、1年内颅内外出血发生率明显高于抗血小板组(均P0.05);与1年内未继发出血的患者比较,1年内继发出血的患者入院NIHSS评分明显增高,初始INR水平明显降低(均P<0.05)。稳态时华法林剂量与年龄呈负相关,与初始华法林剂量呈正相关(均P<0.05)。结论对于非瓣膜病性房颤合并脑栓塞患者而言,华法林抗凝治疗较抗血小板治疗的出血风险高。对于华法林抗凝治疗的非瓣膜病性房颤患者而言,一级预防较二级预防的患者年龄更轻、服药依从性好;低抗凝强度(INR 1.5~2.0)与传统抗凝强度(INR 2.1~3.0)在降低脑卒中发生率、出血风险方面无明显差别;年龄较轻患者华法林初始剂量及稳态时剂量均较高,但脑卒中风险及出血风险较低。
