We have been developing new fabrication tools based on optical radiation pressur e and related phenomena to develop a flexible and accurate microfabrication tec hnology. In this paper, the laser trapping probe for the nano-CMM for assessment , in addition to micromachining technique using a small particle controlled by o p tical radiation pressure and laser aggregation technique are discussed. As the p o sitional detection probe for the nano-CMM, an optically trapped silica particle with 8 mm diameter in forced oscillation state is used. A probe sphere retains a stable position when applied with trapping force by Nd:YAG laser light formed an nu lar and is forced to oscillate by the driving force changed by modulating the in tensity of LD emission. Experintal results show that this vibrational microprobe h as the possibility to achieve positional sensing accuracy of less than 25 nm. As a new micromachining technique, nano-removal process using an optically trapped m icro-grain is proposed. The laser trapping force enables not only to stably trap the diamond grain with asymmetrical shape but also to freely control the positi on with spinning. Using this micro machining tool, the machining experiments of h ydrocarbon film are performed. AFM observation confirmed that the fine groove wi th depths of about 3～4 nm can be fabricated. As an additive process based on ra diation pressure, a laser microstructure fabrication using laser agglomeration p h enomena of colloidal particles aided by radiation pressure is investigated. By c ontrolling laser beam scanning in slurry containing KOH solution and SiO 2 par ticles with a diameter of 140 nm, colloidal particles are aggregated and adhered firmly to a silicon wafer substrate. Using this laser agglomerating process, two-dimensional grid microstructures at the pitch of 5 mm can be fabricated.

The problems existent in the Chinese core journals are approached from different aspects of library and information science. The theoretical basis of bibliometrics and the methods for measuring and selecting core journals are reviewed at full length. The introduction of the models of comprehensive evaluation is a successful example of applying fuzzy mathematics method in selecting core journals. The conclusions drawn by the authors justify Bradford’s Law of Scattering, Garfield’s Law of Concentration and other regularities about scientific journals.

Traditional treatment of infectious diseases is based on compounds that aim to kill or inhibit bacterial growth. The bacterial resistance against antibiotics is a serious issue for public health. Today, new therapeutic targets other than the bacterial wall were deciphered. Quorum sensing or bacterial pheromones are molecules called auto-inducer secreted by bacteria to regulate some functions such as antibiotic resistance and biofilms formation. This therapeutic target is well-studied worldwide, nevertheless the scientific data are not updated and only recent researches started to look into its potential as a target to fight against infectious diseases. A major concern with this approach is the frequently observed development of resistance to antimicrobial compounds. Therefore, this paper aims to provide a current overview of the quorum sensing system in bacteria by revealing their implication in biofilms formation and the development of antibiotic resistance, and an update on their importance as a potential target for natural substances.

目的:探讨腹腔镜与开腹胰十二指肠切除术治疗胰头癌的疗效。方法:回顾分析2017年6月至2021年6月收治的94例胰头癌患者的临床资料。根据手术方法将患者分为对照组(n=43,行开腹胰十二指肠切除术)与观察组(n=51,行腹腔镜胰十二指肠切除术)。比较两组手术相关指标、术后并发症发生率及术前、术后第3天的炎症因子水平。结果:两组手术时间、失血量、输血率、切缘阳性率、淋巴结清扫数量、淋巴结阳性率差异均无统计学意义(P>0.05)。观察组术后排气时间[(3.20±1.04)d vs.(4.32±1.35)d]、术后下床活动时间[(2.75±1.08)d vs.(4.50±1.12)d]、住院时间[(8.25±2.01)d vs.(11.42±3.27)d]短于对照组(P0.05)。术后第3天,观察组前列腺素E2[(211.05±23.22)pg/mL vs.(327.65±39.32)pg/mL]、5-羟色胺[(95.64±11.48)mg/L vs.(127.35±19.10)mg/L]低于对照组(P<0.05)。结论:腹腔镜胰十二指肠切除术治疗胰头癌的安全性、效果较好,与开腹手术相比,腹腔镜手术对术后疼痛因子的影响较小,临床应根据患者情况选择恰当的方案。
