Abstract
The heterogeneity of hepatocellular carcinoma (HCC) and the complexity of the tumor microenvironment (TME) pose challenges to efficient drug delivery and the antitumor efficacy of combined or synergistic therapies. Herein, a metal-coordinated carrier-free nanodrug (named as USFe3+ LA NPs) was developed for ferroptosis-mediated multimodal synergistic anti-HCC. Natural product ursolic acid (UA) was incorporated to enhance the sensitivity of tumor cells to sorafenib (SRF). Surface decoration of cell penetration peptide and epithelial cell adhesion molecule aptamer facilitated the uptake of USFe3+ LA NPs by HepG2 cells. Meanwhile, Fe3+ ions could react with intracellular hydrogen peroxide, generating toxic hydroxyl radical (·OH) for chemodynamical therapy (CDT) and amplified ferroptosis by cystine/glutamate antiporter system (System Xc-), which promoted the consumption of glutathione (GSH) and inhibited the expression of glutathione peroxidase 4 (GPX4). Notably, these all-in-one nanodrugs could inhibit tumor metastasis and induced immunogenic cell death (ICD). Last but not least, the nanodrugs demonstrated favorable biocompatibility, augmenting the immune response against the programmed death-ligand 1 (PD-L1) by increasing cytotoxic T cell infiltration. In vivo studies revealed significant suppression of tumor growth and distant metastasis. Overall, our work introduced a novel strategy for applications of metal-coordinated co-assembled carrier-free nano-delivery system in HCC combination therapy, especially in the realms of cancer metastasis prevention and immunotherapy.

Abstract
The term "zwitterionic polymers" refers to polymers that bear a pair of oppositely charged groups in their repeating units. When these oppositely charged groups are equally distributed at the molecular level, the molecules exhibit an overall neutral charge with a strong hydration effect via ionic solvation. The strong hydration effect constitutes the foundation of a series of exceptional properties of zwitterionic materials, including resistance to protein adsorption, lubrication at interfaces, promotion of protein stabilities, antifreezing in solutions, etc. As a result, zwitterionic materials have drawn great attention in biomedical and engineering applications in recent years. In this review, we give a comprehensive and panoramic overview of zwitterionic materials, covering the fundamentals of hydration and nonfouling behaviors, different types of zwitterionic surfaces and polymers, and their biomedical applications.

Abstract
At present, cardiovascular stent intervention faces clinical complications such as delayed endothelialization, late thrombosis and restenosis after implantation. In this work, a kind of bifunctional polymer brush-grafted coronary stent with anticoagulant and endothelial functions was developed. First, a block copolymer brush with zwitterionic structure consisting of sulfoethyl methacrylate (SBMA) and glycidyl methacrylate (GMA) was surface-induced grafted onto the surface of bare metal coronary stent by atom transfer radical polymerization. The diethylenetriamine NONOate (DETA NONOate), acted as nitric oxide (NO) donor to promote endothelialization, was then attached to polyglycidyl methacrylate (PGMA) brush by a reactive epoxy group to produce NO. The process of chemical modification and the release behavior of NO were characterized in detail. Moreover, the results of anticoagulant test, cytotoxicity test, endothelial cells (ECs) proliferation test and animal experiment of this bifunctional polymer brush-grafted coronary stent we proposed indicate that the zwitterion modified and NO supplied bifunctional coatings has good anticoagulant property, no cytotoxicity and significant endothelialization effect. This work opens the door to combine biological activity of NO and anticoagulant effect of zwitterions, which has great potential to address post-operative side effects associated with restenosis and late stent thrombosis.

Abstract
Nanosized drug delivery systems have emerged to improve the therapeutic performance of anticancer drugs. Here, an amphiphile-based nanoparticle consisting of amphiphilic prodrug N-[3b-acetoxy-urs-12-en-28-oyl]-amino-2-methylpiperazine was developed (UP12 NPs) with uniform sizes (~100 nm), which possessed the advantages of small molecules and nanomedicine. The positively charged UP12 NPs significantly enhanced the cellular drug uptake on HepG2 cells than negatively charged UA NPs. Meanwhile, UP12 and these therapeutic amphiphile-based nanoparticles could induce cell apoptosis more efficiently than that of UA and UA NPs. Moreover, molecular docking demonstrated that the UP12 and intercellular adhesion molecule 1 (ICAM-1) could dock well. UP12 and UP12 NPs significantly decreased the mRNA expression of ICAM-1 and inhibited the migration and adhesion of liver cancer cells (HepG2 cells), which indicated that UP12 might be one of the potential ICAM-1 inhibitors. In vivo, UP12 NPs enhanced tumor accumulation, inhibited tumor lung metastasis and showed good biocompatibility. Overall, UP12 or UP12 NPs could be developed as prospective drugs for cancer metastasis therapy via ICAM-1 mediated cell adhesion. STATEMENT OF SIGNIFICANCE: In this study, we fabricated the therapeutic amphiphile-based nanoparticles by assembly of ursolic acid piperazine derivative N-[3b-acetoxy-urs-12-en-28-oyl]-amino-2-methylpiperazine (name as UP12 NPs) with low cytotoxicity. UP12 NPs exhibited spherical morphology and uniform sizes. Particularly, these therapeutic amphiphile-based nanoparticles significantly enhanced tumor accumulation and inhibited tumor lung metastases via intercellular adhesion molecule 1 (ICAM-1) mediated cell adhesion.

Abstract
In the treatment of coronary artery disease (CAD), the use of stent implantation often leads to clinical complications such as restenosis, delayed endothelial healing, and thrombosis. Here, we develop a double drug sustained-release coating for the stent surface by grafting heparin/NONOate nanoparticles (Hep/NONOates). The Hep/NONOates and surface modification of the stent were characterized by X-ray photoelectron spectroscopy, attenuated total reflection Fourier-transform infrared spectroscopy, static water contact angle, and scanning electron microscopy (SEM), and the release behaviors of the anticoagulant, heparin (Hep) and the bioactive molecule, nitric oxide (NO) were studied. Furthermore, the blood compatibility and cytotoxicity of the modified stent were evaluated by whole blood adhesion and platelet adhesion tests, hemolysis assay, morphological changes of red blood cells, plasma recalcification time assay, in vitro coagulation time tests, and MTT assay. Finally, the results of a rabbit carotid artery stent implantation experiment showed that the double drug sustained-release coating for the stent can accelerate regeneration of endothelial cells and keep good anticoagulant activity. This study can provide new design ideas based on nanotechnology for improving the safety and effectiveness of drug-eluting stents.

Abstract
In this paper, novel heparin-mimicking hyperbranched polyester nanoparticles (HBPE-SO3 NPs) with abundant of sulfonated acid functional groups were synthesized, and their antithrombogenicities were further evaluated. Further, a label-free electrochemical aptamer biosensor (aptasensor) based on HBPE-SO3 NPs modified electrode was developed for thrombin (TB) detection in whole blood. Meanwhile, the anti-biofouling properties of different modified electrodes were studied by whole blood and platelet adhesion test, hemolysis assay and morphological changes of red blood cells in vitro. Besides, the thrombin-binding aptamer was selected as receptor for the proposed aptasensor, which has excellent binding affinity and selectivity for TB. When binding to TB, the electron transfer taking place at the modified electrode interface was inhibited that can attribute to the stereo-hindrance effect, resulting in the decreased current response. This aptasensor showed excellent electrochemical properties with a wide detection range and a low detection limit of 0.031pM (S/N = 3), and provided high selectivity, long-term stability and good reproducibility. Finally, the sensitively detection of TB in whole blood samples directly was achieved by this aptasensor we proposed, which suggested its great potential for TB detection in the clinic.

Abstract
Mesoporous silica has been developed for the modification of titanium surfaces that are used as implant materials. Yet, the traditional modification methods failed to effectively construct mesoporous silica on the titanium surface evenly and firmly, in which the interaction between mesoporous silica and titanium was mainly physical. Here, in situ growth of mesoporous silica on a titanium surface was performed using a simple evaporation-induced self-assembly strategy. Meantime, in situ introduction of drugs (heparin and vancomycin) to mesoporous silica was also adopted to improve the drug-loading amount. Both the above-mentioned processes were completed at the same time. Transmission electron microscopy, N2 adsorption-desorption isotherms, Fourier transform infrared spectroscopy, scanning electron microscopy, and water contact angle measurements were used to characterize the structure of the mesoporous silica film. Results indicated that the mesoporous silica film that in situ grew on the titanium surface was smooth, thin, transparent, and stable. Cytotoxicity, proliferation performance of osteoblast cells, and in vitro and in vivo studies of the antibacterial activity of the coating were tested. This is the first study to modify the titanium surface by the in situ growth of a mesoporous silica coating with two kinds of drugs. The stability of the mesoporous silica coating can be attributed to the chemical bonding between dopamine and silicon hydroxyl of the mesoporous silica coating, and the smooth surface of mesoporous silica is a result of the method of in situ growth. The large amount of drug-loading also could be ascribed to the in situ introduction of drugs during the synthetic process. The strategy proposed in this work will bring more possibilities for the preparation of advanced functional materials based on the combination of mesoporous structure and metallic materials.

Abstract
Silicone catheter has been widely used in peritoneal dialysis. The research missions of improving blood compatibility and the ability of resisting bacterial adhesion of silicone catheter have been implemented for the biomedical requirements. However, most of modification methods of surface modification were only able to develop the blood-contacting biomaterials with good hemocompatibility. It is difficult for the biomaterials to resist bacterial adhesion. Here, agarose was selected to resist bacterial adhesion, and heparin was chosen to improve hemocompatibility of materials. Both of them were loaded into mesoporous silica nanoparticles (MSNs), which were successfully modified on the silicone film surface via electrostatic interaction. Structures of the mesoporous coatings were characterized in detail by dynamic light scattering, transmission electron microscopy, Brunauer-Emmett-Teller surface area, thermogravimetric analysis, Fourier transform infrared spectroscopy, scanning electron microscope, and water contact angle. Platelet adhesion and aggregation, whole blood contact test, hemolysis and related morphology test of red blood cells, in vitro clotting time tests, and bacterial adhesion assay were performed to evaluate the anticoagulant effect and the ability of resisting bacterial adhesion of the modified silicone films. Results indicated that silicone films modified by MSNs had a good anticoagulant effect and could resist bacterial adhesion. The modified silicone films have potential as blood-contacting biomaterials that were attributed to their biomedical properties.

Abstract
Polyethylene glycol (PEG) and heparin (Hep) were grafted onto polysulfone (PSF) membrane by plasma-induced surface modification to prepare PSF-PEG-Hep membranes used for artificial lung. The effects of plasma treatment parameters, including power, gas type, gas flow rate, and treatment time, were investigated, and different PEG chains were bonded covalently onto the surface in the postplasma grafting process. Membrane surfaces were characterized by water contact angle, PEG grafting degree, attenuated total reflectance-Fourier transform infrared spectroscopy, ultraviolet-visible spectrophotometry, X-ray photoelectron spectroscopy, critical water permeability pressure, and scanning electron microscopy. Protein adsorption, platelet adhesion, and coagulation tests showed significant improvement in the hemocompatibility of PSF-PEG-Hep membranes compared to pristine PSF membrane. Gas exchange tests through PSF-PEG6000-Hep membrane showed that when the flow rate of porcine blood reached 5.0 L/min, the permeation fluxes of O2 and CO2 reached 192.6 and 166.9 mL/min, respectively, which were close to the gas exchange capacity of a commercial membrane oxygenator. © 2016 Wiley Periodicals, Inc.

Abstract
AIM Vascular endothelial-cadherin (VE-cadherin) is specifically expressed by outgrowth endothelial cells (OECs). Zwitterionic stent showed high antifouling and excellent blood compatibility. Therefore, we hypothesized that anti-VE-cadherin antibody-coated zwitterionic stents (VE-cad-Z stents) would promote re-endothelialization, reduce neointimal formation, and resist thrombus. METHODS VE-cad-Z stents were examined using platelet adhesion test, platelet activation, and OEC capture ability in vitro. In vivo effect of VE-cad-Z stents on re-endothelialization, thrombus-resistance, and neointima hyperplasia was investigated in left common carotid arteries of rabbits (n=15). RESULTS In vitro, VE-cad-Z stents showed better platelet-resistance and OEC-capture ability (DNA concentration: 297.23±22.71 versus 67.49±15.26 ng/µL, P<0.01). In vivo, VE-cad-Z stents exhibited better patency rate than bare metal stents (BMS) (15/15 versus 12/15), and it significantly reduced platelet adhesion and neointima formation (neointima area: 1.13±0.05 versus 1.00±0.05mm(2), P<0.01 and 3.04±0.11versus 1.05±0.06mm(2), P<0.01, at 3 and 30 days, respectively; % stenosis: 20.99±0.98 versus 18.72±0.97, P<0.01 and 56.46±2.20 versus 19.45±1.24, P<0.01, at 3 and 30 days, respectively). CONCLUSION These data suggested that VE-cad-Z stents could specifically capture OECs, consequently promote endothelial healing, and also reduce platelet adhesion and neointima formation.
