作者： The Expert Writing Committee of the Chinese Expert Consensus on Clinical Applications of Drug-Coated Balloon(2.(nd)Edition) Jun-Bo GE y.n-Dai CHEN 不详 Zhongshan Hospital Fudan University Chinese PLA General Hospital

Percutaneous coronary.interventions have progressed through the era of plain balloon dilation, bare-metal stent insertion to drug-eluting stent treatment, which has significantly.reduced the acute occlusion and restenosis rates of target vessels and improved patient prognosis, making drug-eluting stents the mainstream interventional treatment for coronary.artery.disease. In recent y.ars, drug-coated balloons(DCBs) have become a new treatment strategy.for coronary.artery.disease, and the drugs used in the coating and the coating technology.have progressed in the past y.ars. Without permanent implant, a DCB delivers antiproliferative drugs rapidly.and uniformly.into the vessel wall via the excipient during a single balloon dilation. Many.evidence suggests that DCB angioplasty.is an effective measure for dealing with in-stent restenosis and de novo lesions in small coronary.*** more clinical studies are published, new evidence is emerging for the use of DCB angioplasty.in a wide range of coronary.diseases, and the indications are expanding internationally. Based on the latest research from China and elsewhere, the Expert Writing Committee of the Chinese Expert Consensus on Clinical Applications of Drug-Coated Balloon has updated the previous DCB consensus after evidence-based discussions and meetings in terms of adequate preparation of in-stent restenosis lesions, expansion of the indications for coronary.de novo lesions, and precise guidance of DCB treatment by.intravascular imaging and functional evaluation.

植物是有机污染物的重要储存体。有机污染物可以跨叶面进入植物体，通过食物链的富集作用，造成潜在的环境和健康风险。气孔和角质层是叶面吸收有机污染物的两个主要途径，角质层作为典型的大气-植物体微界面，是植物和大气中有机污染物的双向运输障碍。相对于气孔的直接吸收，有机污染物在角质层上的跨膜行为更加复杂。本文总结了有机污染物的叶面吸收途径，综述了有机污染物的叶面吸收机理及影响因素，重点阐述了有机污染物跨角质层的运输过程，并展望了未来的研究趋势和发展方向，为更好了解有机污染物的叶面吸收机理及其在环境中的归趋行为提供理论基础。

Many.phenomena in nature and technology.are associated with the filtration of suspensions and colloids in porous media. Two main ty.es of particle deposition,namely. cake filtration at the inlet and deep bed filtration throughout the entire porous medium, are studied by.different models. A unified approach for the transport and deposition of particles based on the deep bed filtration model is proposed. A variable suspension flow rate, proportional to the number of free pores at the inlet of the porous medium, is considered. To model cake filtration, this flow rate is introduced into the mass balance equation of deep bed filtration. For the cake filtration without deposit erosion,the suspension flow rate decreases to zero, and the suspension does not penetrate deep into the porous medium. In the case of the cake filtration with erosion, the suspension flow rate is nonzero, and the deposit is distributed throughout the entire porous medium. An exact solution is obtained for a constant filtration function. The method of characteristics is used to construct the asy.ptotics of the concentration front of suspended and retained particles for a filtration function in a general form. Explicit formulae are obtained for a linear filtration function. The properties of these solutions are studied in detail.
