Comparison of Multivessel Versus Culprit-Vessel-Only Revascularization in Patients With STEMI and Multivessel Disease During Primary PCI: In-Hospital Outcomes From the CCC-ACS Project in China.

Background: The consensus on whether acute ST-segment elevation myocardial infarction (STEMI) patients with multivessel coronary artery disease (MVD) benefit from complete revascularization during primary percutaneous coronary intervention (PCI) is unclear.

Aims: This study aims to assess the impact of multivessel PCI (MV-PCI) versus culprit-vessel-only PCI (CV-PCI) on in-hospital outcomes in a Chinese population.

Methods: We evaluated STEMI patients with MVD undergoing PCI, registered in the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome (CCC-ACS) project, from November 2014 to December 2019.

Predictive factors for multivessel disease in patients with acute coronary syndrome: analysis from the CCC-ACS project in China.

Background: Multivessel disease(MVD) is linked to a poorer prognosis, increased complications, longer hospital stays, and higher in-hospital mortality when compared to single-vessel disease(SVD).The purpose of this study is to explore the clinically relevant predictors of acute cornary syndrome (ACS) combined with MVD.

Methods: This multicenter retrospective study included 68,378 ACS patients from 240 hospitals.

Tight focusing of the vector optical field with polarization varying along complex curves of the Poincaré sphere.

Different from the scalar optical field with spatially uniform polarization, the vector optical field exhibits inhomogeneous distribution of polarization on the cross section. Manipulating the variation of polarization in a single optical beam is important to acquire a flexible and controllable focused optical field. Previous studies mainly focused on the vector optical field with its polarization varying along a circular trajectory of the Poincaré sphere.

Transformable Colloidal Polymer Particles with Ordered Internal Structures.

Based on studies combining experiments and simulations, internally ordered colloidal particles that are able to undergo morphological transformations both in shape and internal structure are presented. The particles are prepared by emulsion solvent evaporation-induced 3D soft confined assembly of di-block copolymer polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP). Control over the solvent selectivity leads to a dramatic change in shape and internal structure for particles.

Formation Mechanisms of Porous Particles from Self-Assembly of Amphiphilic Diblock Copolymers inside an Oil-in-Water Emulsion Droplet upon Solvent Evaporation.

The formation mechanisms of porous particles from self-assembly of amphiphilic diblock copolymers inside an oil-in-water emulsion droplet upon evaporation of the organic solvent are investigated based on Monte Carlo simulations for the first time. A morphological diagram of particles is constructed as a function of the surfactant concentration (φ) and the copolymer composition characterized by the volume fraction of the hydrophilic B block ( f). Particles with various morphologies are predicted.

Phase behavior of ABC-type triple-hydrophilic block copolymers in aqueous solutions.

The phase behavior of symmetric ABC triple-hydrophilic triblock copolymers in concentrated aqueous solutions is investigated using a simulated annealing technique. Two typical cases, in which the hydrophilicity of the middle B-block is either stronger or weaker than that of the end A- and C-blocks, are studied. In these two cases, a variety of phase diagrams are constructed as a function of the volume fraction of the B-block and the copolymer concentration ([Formula: see text] for both non-frustrated and frustrated copolymers.
