Background: Pericoronary fat stranding (PCFS) is a novel noninvasive imaging sign of coronary inflammation, and has important implications for cardiovascular risk stratification, and the outcome of percutaneous coronary intervention (PCI) for coronary heart disease patients with pericoronary fat stranding remains unknown. Aim: We report two rare cases of PCI-treated coronary heart disease patients with severe PCFS. Case Presentation: This is the first report of two rare cases of PCI for patients with coronary heart disease surrounded by severe PCFS. We demonstrated that the outcome in these cases is poor, and in-stent restenosis or occlusion occurs rapidly within 2- 6 months following PCI. However, Case 2 underwent coronary artery bypass grafting after the rapid occurrence of in-stent occlusion, and the bypass graft remained intact over the 5 years following coronary artery bypass grafting. Conclusion: Coronary artery bypass grafting rather than PCI may be appropriate for coronary heart disease patients with severe PCFS.

目的观察冠状动脉CT成像(CCTA)中,根据冠状动脉钙化(CAC)近端与远端冠状动脉管腔CT值及校正后冠状动脉强化值(CCO)差值评估钙化部位管腔狭窄的准确度。方法对CCTA显示钙化的233支主要冠状动脉(左前降支、左回旋支和右冠状动脉),根据狭窄程度分为轻度狭窄组、中度狭窄组、重度狭窄组和完全闭塞组,比较各组CCO差值,分析以钙化近远端CCO差值评估冠状动脉狭窄的准确度。结果完全闭塞组CCO差值高于轻度狭窄组、中度狭窄组和重度狭窄组(P0.05);中度狭窄组和重度狭窄组CCO差值高于轻度狭窄组(P<0.001)。以钙化近远侧CCO差值0.0869作为诊断界点,其诊断冠状动脉≥50%狭窄的敏感度、特异度、阳性预测值和阴性预测值分别为76.67%、75.47%、91.39%和48.78%;以0.2070作为诊断界点时,其诊断冠状动脉闭塞的敏感度、特异度、阳性预测值和阴性预测值分别为91.84%、79.89%、54.88%和97.35%。结论冠状动脉钙化近远端管腔CCO差值随狭窄程度加重而升高,以之作为评价指标,可明显提高评估冠状动脉钙化及狭窄程度的准确性。

Methanol is one of the most important basic feedstock for the organic chemical industry and also is a potential fuel. Although the technology for the production of methanol is generally considered mature, much attention is still being paid to the improvements of the process, equipment and catalyst. As compared with the existing gas-solid two-phase process, the three-phase (also called the slurry phase or liquid phase) process has the advantages of simpler structure of the reactor, more uniform temperature distribution in the reactor, higher one-through conversion of syngas, ease of charging and discharging the catalyst, etc. So the investment, energy consumption, and production costs are much lower. The improvement of the catalyst is also a focus of research and development.

The response of rice to N fertilizer applicationhas shown that high rates of N application donot always ensure a proportional increase inyield due to high N losses. A model, ORYZA-0 was developed by ten Berge for designingoptimum N fertilizer management strategy inrice. We evaluated the performance ofORYZA-0 in Jinhua, Zhejiang Province. ORYZA-0 includes N uptakes, partition-ing of N among the organs, and utilization ofleaf N in converting solar energy to dry mat-ter. It can predict the amount and time of Nfertilizer application to achieve a maximumbiomass or yield combining with Price algo-rithm optimization procedure.

由于多轴向同时振动不能简单地采用单轴依次振动来完全等效,对此提出了一种保持结构关键部位三轴与单轴随机振动应力等效的载荷谱裁剪方法。通过推导线性系统三轴随机振动载荷到结构关键点响应间的变换关系式,提出三轴载荷谱均方根值裁剪方法;综合考虑试件中不同零部件的重要程度和材料强度,基于试件关键部位在三轴载荷下的等效应力与在单轴依次载荷下的最大等效应力之比应等于裁剪前后该点应力响应功率谱均方根值之比,分类定义了三轴载荷谱均方根值裁剪准则,同时为避免因谱型裁剪的多样性造成试验的不确定性,制定了三轴载荷谱的保型裁剪原则。以某典型舱段电路板为例,验证了该三轴载荷谱裁剪方法的有效性。利用该方法得到的三轴载荷谱,不仅可以避免结构重要零部件过试验或欠试验,而且也保证了关键点应力的等效性和裁剪谱型的确定性。
