目的评价冠状动脉计算机断层成像(CTCA)对冠状动脉斑块性质的评价能力,比较不同斑块性质患者的临床诊断结果和高敏C反应蛋白(HS-CRP)水平的差异。方法选择因怀疑冠状动脉病变就诊的患者,均在接受CTAT检查后进行冠状动脉造影(CAG),CAG检查结果冠状动脉狭窄率≥50%且CTCA检查存在斑块者纳入研究。根据CTCA检查显示斑块的CT值将患者分为软斑块组、钙化斑块组和混合斑块组,比较各组间的临床特征。同时,比较急性冠状动脉综合征(ACS)患者与慢性稳定型缺血性心脏病(SIHD)患者以及不同HS-CRP水平患者CTAT斑块分布的特点,评价软斑块联合HS-CRP识别ACS患者的价值。结果共有106例患者入选该研究,其中66例(62.3%)为软斑块组,13例(12.3%)为钙化斑块组,27例(25.4%)为混合斑块组,三组斑块的CT值分别为(35.2±11.8)、(252.3±40.9)和(88.3±19.6)HU。除钙化斑块组患者年龄高于软斑块组和混合组(P=0.036),三组间其他临床因素以及血肌酐、血肌钙蛋白和HS-CRP水平比较差异均无统计学意义(P>0.05)。ACS组与SIHD组、HS-CRP水平正常组与HS-CRP水平升高组患者的斑块分布情况均无统计学差异(P>0.05)。8例HS-CRP水平升高且合并软斑块的患者均诊断为ACS。结论CTCA可区别不同性质的冠状动脉斑块。不同临床诊断结果和不同HS-CRP水平患者的CTCA斑块分布并无差异,而HS-CRP水平升高且斑块为软斑块的患者均诊断为ACS。

背景:探讨基于步法的足部触地模式对乒乓球运动中下肢关节运动特征的影响,可为指导下肢训练提供科学依据。目的:对比乒乓球运动中不同触地模式下的运动学和动力学差异。方法:使用动作捕捉和三维测力台同步采集17名专业乒乓球运动员在正常触地和全脚掌触地模式下优势侧下肢的运动学和动力学数据。配对样本t检验用于分析关节角度、地面反作用力、关节反作用力和关节力矩等离散指标的统计学差异;统计参数映射用于分析足底压力中心移动轨迹和膝关节力矩等时间序列数据的统计学差异。结果与结论:①正常触地模式下的膝关节内翻、侧向地面反作用力、膝关节垂直反作用力和伸膝力矩峰值显著高于全脚掌触地模式;②在足底压力中心移动距离中的89%-91%运动阶段,正常触地模式压力中心显著远于全脚掌触地模式;③在X轴力矩曲线中的23%-38%运动阶段,正常触地模式的伸膝力矩显著大于全脚掌触地模式;④在Y轴力矩曲线的8%-18%运动阶段,全脚掌触地模式显著大于正常触地模式。通过对比不同触地模式的下肢生物力学特征值和统计参数映射分析结果,认为全脚掌触地模式可能是影响乒乓球运动表现的重要因素。乒乓球运动中需要针对性地对触地模式进行调整和练习,避免使用全脚掌触地模式,提升乒乓球运动者下肢运动能力。

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

The electrical oscillations across a liquid membrane in water/oil/water system was studied with octanol as oil phase by introducing two opposite charged surfactants in oil and aqueous phase, respectively. The sustained and rhythmic oscillation was observed. To a certain extent, the features of the oscillation （e.g. induction time, frequency, life time and orientation of the pulse pikes） strongly depend on the property of surfactant, dissolved in octanol. The mechanism may be explained by the formation and destruction of dual-ion surfactant membrane accompanying with emulsification at the interface and considering the coupling effect of diffusion and associated reaction in the vicinity of the interface.

Angiogenesis in atherosclemtic plaque plays a critical role in the mechanism of atherosclerotic physiopathology. Present consensus shows that angiogenesis in atherosclerotic plaque is mainly resulted in hypoxia, inflammation and some pro-angiogenic factors. The homeostasis in plaque, which is hypoxic and infiltrated by inflammatory cells, may lead to angiogenesis, increase the plaque instability and the incidence rate of vascular events. This article reviews the progression of pathogenetic mechanism, physiopathological significance, relevant detecting technique and corresponding therapeutic methods of Chinese and Western medicine of angiogenesis in atherosclerotic plaque, so as to provide more theoretical basis for atherosclerotic clinical treatment.
