Perioperative parecoxib administration reduces postoperative pain, opioid consumption, and adverse events in adult patients. However, the efficacy and safety of parecoxib in children remain unclear. This meta-analysis included related published studies to address this concern. Eight databases in the literature until February 2015 were systematically explored to identify randomized controlled trials （RCTs） comparing perioperative parecoxib administration and placebo/standard treatments for acute postoperative pain in children. Primary outcomes were postoperative pain scores and adverse events. The Face, Legs, Activity, Crying, Consolability scale was used to score pain in children younger than 6 years, whereas the Visual Analog Scale was used in children older than 6 years. Secondary outcomes were sedation scores （measured using the Ramsay scale）, agitation scores （measured using the Sedation-Agitation Scale）, and opioid consumption. The methodological quality of RCTs was independently assessed in accordance with the ＂Risk of bias＂ of Cochrane Collaboration. Data were analyzed using Review Manager 5.2. Twelve RCTs involving 994 patients met the inclusion criteria. Compared with children who received placebo treatment, those who received parecoxib demonstrated lower early （2 h） and later （12 h） postoperative pain scores; lower incidence rates of postoperative nausea, vomiting, and agitation; higher early （1 h） postoperative sedation scores; and lower agitation scores. Similarly, children who received parecoxib had lower early （2 h） and later （12 h） postoperative pain scores, lower incidence rates of postoperative nausea and vomiting, and lower early （1 h） postoperative sedation scores compared with those who received standard treatments; however, these children showed no significant difference in agitation scores. Unfortunately, data on the effect of parecoxib on opioid consumption were insufficient. Overall, these results suggested that perioperative parecoxib admini

Let G be a graph and H a subgraph of G. A backbone-k-coloring of （G, H） is a mapping f： V（G） → {1,2,…,k} such that If（u）- f（v）｜ ≥ 2 if uv ∈ E（H） and ｜f（u）- f（v）｜ ≥ 1 if uv ∈ E（G）／E（H）. The backbone chromatic number of （G, H） denoted by Xb（G, H） is the smallest integer k such that （G, H） has a backbone-k-coloring. In this paper, we prove that if G is either a connected triangle-free planar graph or a connected graph with mad（G）〈 3, then there exists a spanning tree T of G such that Xb（G, T） ≤ 4.

A vertex distinguishing edge coloring of a graph G is a proper edge coloring of G such that any pair of vertices has the distinct sets of colors. The minimum number of colors required for a vertex distinguishing edge coloring of a graph C is denoted by Xs＇8（G）. In this paper, we obtained upper bounds on the vertex distinguishing chromatic index of 3-regular Halin graphs and Halin graphs with △（G） ≥ 4, respectively.

Abrasive is the one of key influencing factors during chemical mechanical polishing（CMP） process. Currently, α-Alumina （α-Al2O3） particle, as a kind of abrasive, has been widely used in CMP slurries, but their high hardness and poor dispersion stability often lead to more surface defects. After being polished with composite particles, the surface defects of work pieces decrease obviously. So the composite particles as abrasives in slurry have been paid more attention. In order to reduce defect caused by pure α-Al2O3 abrasive, α-alumina-g-polystyrene sulfonic acid （α-Al2O3-g-PSS） composite abrasive was prepared by surface graft polymerization. The composition, structure and morphology of the product were characterized by Fourier transform infrared spectroscopy（FTIR）, X-ray photoelectron spectroscopy（XPS）, time-of-flight secondary ion mass spectroscopy（TOF-SIMS）, and scanning electron microscopy（SEM）, respectively. The results show that polystyrene sulfonic acid grafts onto α-Al2O3, and has well dispersibility. Then, the chemical mechanical polishing performances of the composite abrasive on glass substrate were investigated with a SPEEDFAM-16B-4M CMP machine. Atomic force microscopy（AFM） images indicate that the average roughness of the polished glass substrate surface can be decreased from 0.835 nm for pure α-Al2O3 abrasive to 0.583 nm for prepared α-Al2O3-g-PSS core-shell abrasive. The research provides a new and effect way to improve the surface qualities during CMP.

失效的“压舱石”:经济安全化的现实转向

经济安全化是国家通过安全叙述将非安全的经济议题转化为安全议题的过程。在国家认为经济合作的收益将损害其在权力竞争中的整体所得时,或者在国家间政治外交关系遇到巨大震荡或冲击时,国家安全逻辑会超越经济逻辑而生效。此时,安全与经济问题在刻意煽动下交织碰撞,国家间密切的经贸关系不仅难以成为管控两国矛盾与分歧的“压舱石”,反而会被国家视作现存的“安全威胁”,成为某些国家中断或破坏双边政治经济联系的借口与手段。国家间存在的经济相互依赖关系也会随之成为安全化操纵国维护与拓展权力、进行地缘政治竞争和打击、操纵他国的战略性工具。因此,文章以存在紧密经济相互依赖的中美与俄欧关系为案例,在比较中美、俄欧之间不同经济安全化动因的基础上,分析经济安全化转向背后的选择逻辑,为中国更好地应对经济安全化挑战、更有针对性地发挥“经济压舱石”作用提供一定思考。
