Abstract
In this study, a targeted graphene quantum dot-cationic polymer composite gene vector with endothelial cell-targeting CAG peptide was successfully designed and prepared. This vector could efficiently bind and deliver the therapeutic gene pZNF580 to endothelial cells (HUVECs). At a concentration of less than 40 μg mL-1, the results of the CCK-8 assay showed that the relative cell viability of each composite gene vector was greater than 80%, and the results of the flow cytometry assay showed that C-GQDs-PEI-PEG-CAG/pZNF580 (88.96%) and N-GQDs-PEI-PLGA-PEG-CAG/pZNF580 (87.70%) treated groups showed significantly higher cell viability than the positive control group Lip2000/pZNF580 (56.76%). The results of in vitro cell transfection and western blot experiments confirmed that the composite gene vector was able to deliver pZNF580 efficiently and enable the high expression of the ZNF580 protein in HUVECs. The results of the EdU assay, wound healing and Transwell experiments indicated that the composite gene vector/pZNF580 nanoparticles (NPs) could significantly promote the proliferation and migration. The results of the EdU method showed that the proliferative ability of C-GQDs-PEI-PLGA/pZNF580 (84.96 ± 1.99%) and N-GQDs-PEI-PLGA/pZNF580 (85.01 ± 1.31%) treatment groups for HUVECs was significantly higher than that of the positive control group Lip2000/pZNF580 (77.89 ± 2.18%). The results of the scratch assay showed that the cell migration rate of C-GQDs-PEI-PLGA-PEG-CAG/pZNF580 (93.08 ± 1.97%) and N-GQDs-PEI-PLGA-PEG-CAG/pZNF580 (91.99 ± 1.52%) groups was significantly higher than that of the positive control group Lip2000/pZNF580 (85.03 ± 2.21%). In addition, the results of the in vitro angiogenesis assay showed that the C-GQDs-PEI-PLGA-PEG-CAG/pZNF580 and N-GQDs-PEI-PLGA-PEG-CAG/pZNF580 groups had significantly higher angiogenesis-promoting ability than the positive control group, Lip2000/pZNF580.The present study provides a highly efficient and low-toxic method to promote endothelial cell migration in the field of regenerative medicine and a low-toxicity strategy to promote endothelial layer formation, which provides new possibilities for future vascular regeneration therapy.

Abstract
As an urgently needed device for vascular diseases, the small-diameter vascular graft is limited by high thrombogenicity in clinical applications. Rapid endothelialization is a promising approach to construct an antithrombogenic inner surface of the vascular graft. The main bottleneck for rapid endothelialization is the adhesion, migration, and proliferation of endothelial cells (ECs) in situ of the small-diameter vascular graft. Herein, we innovatively fabricated an intelligent gene delivery small-caliber vascular graft based on electrospun poly(lactic acid-co-caprolactone) and gelatin for rapid in situ endothelialization. The graft surface was co-modified with EC adhesive peptide of Arg-Glu-Asp-Val (REDV) and responsive gene delivery system. REDV can selectively adhere ECs onto the graft surface; subsequently, the overexpressed matrix metalloproteinase by ECs can effectively cleave the linker peptide GPQGIWGQ-C; and finally, the gene complexes were intelligently and enzymatically released from the graft surface, and thereby, the gene can efficiently transfect ECs. Importantly, this enzymatically releasing gene surface has been proven to be safe and temporarily stable in blood flow owing to the biotin-avidin interaction to immobilize gene complexes on the inner surface of vascular grafts through the GPQGIWGQ-C peptide linker. It has the advantage of specifically adhering the ECs to the surface and smartly transfecting them with high transfection efficiency. The co-modified surface has been demonstrated to accelerate the luminal endothelialization in vivo, which might be attributed to the synergistic effect of REDV and effective gene transfection. Particularly, the intelligent and responsive gene release surface will open a new avenue to enhance the endothelialization of blood-contacting devices.

Abstract
Smart polymers as ideal drug nanocarriers have attracted much attention due to the effective drug delivery, internalization and release once triggered by intracellular stimuli, as well as reduced cytotoxicity. We here reported the anionic micelle consisting of copolymer (PEG-b-PAsp) and a PBE (Phenylboronic Ester) group grafted, which can achieve fast response to intracellular ROS and enhanced anti-tumor activity. With this, PEG-b-PAsp-g-PBE/DOX system showed better tumor growth inhibition when studied on HeLa cell lines with high level of intracellular ROS and its subcutaneous tumor models. Additionally, the administration of PEG-b-PAsp-g-PBE/DOX did cause significantly lower systemic toxicity in comparison with free DOX. Hence, PEG-b-PAsp-g-PBE could be a highly efficient and safe nanocarrier to improve the efficacy of chemotherapeutic.

Abstract
Redox-responsive cationic polymers have gained considerable attention in gene delivery due to low cytotoxicity and spatio-temporal release of DNA into the cells. Here, we reported the synthesis of reducible disulfide conjugated polyethyleneimine (1.8 kDa) (denoted as SS-PEI) and its application to transfer pEGFP-ZNF580 plasmid (pZNF580) into EA.hy926 cell. This reducible SS-PEI polymer was prepared by one-step polycondensation reaction of low molecular weight PEI with bis-(p-nitrophenyl)-3,3'-dithiodipropionate. The SS-PEI successfully condensed pZNF580 into nano-sized complexes (170 ± 1.5 nm to 255 ± 1.6 nm) with zeta potentials of 3 ± 0.4 mV to 17 ± 0.9 mV. The complexes could be triggered to release pZNF580 when exposed to the reducing environment of 5 mM dithiothreitol. Besides, the SS-PEI exhibited low cytotoxicity. In vitro transfection results showed that SS-PEI exhibited good transfection efficiency comparable to PEI25kDa. Thus, the SS-PEI could act as an reducible gene carrier with good transfection efficiency and low cytotoxicity.

Abstract
Strong specificity for cancer cells is still the main challenge to deliver drugs for the therapy of cancer. Herein, we developed a convenient strategy to prepare a series of 5-boronopicolinic acid (BA) modified tumor-targeting drug delivery systems (T-DDSs) with strong tumor targeting function. An anti-tumor drug of camptothecin (CPT) was encapsulated into poly(lactide-co-glycolide)-g-polyethylenimine (PLGA-PEI) to form drug-loaded nanoparticles (NP/CPT). Then, the surface of NP/CPT was coated by BA with different polymer and BA molar ratios of 1:1, 1:5, 1:10 and 1:20 via electrostatic interaction to obtain T-DDSs with enhanced biocompatibility and specificity for tumor cells. The introduced BA can endow drug-loaded NPs with high targeting ability to tumor cells because of the overexpression of sialic acids (SA) in tumor cells, which possessed strong interaction with BA. Those T-DDSs exhibited good biocompatibility according to the results of MTT assay, hemolysis test and cellular uptake. Moreover, they were capable of decreasing the viability of breast cancer cell line 4T1 and MCF-7 cells with no obvious cytotoxicity for endothelial cells. Especially, T-DDS with 1:20 molar ratio displayed much higher cellular uptake than other groups, and also exhibited highly efficient in vivo anti-tumor effect. The significantly high targeting function and biocompatibility of T-DDSs improved their drug delivery efficiency and achieved good anti-tumor effect. The BA decorated T-DDSs provides a simple and robust strategy for the design and preparation of DDSs with good biocompatibility and strong tumor-specificity to promote drug delivery efficiency.

Abstract
Rheumatoid arthritis (RA) is a kind of systemic autoimmune disease, and patients with RA usually suffer serious pain, resulting in low quality of life. The development of drug delivery systems (DDSs) provides a valid approach for RA therapy via inhibiting the secretion of inflammatory cytokines from macrophages. As a prevailing drug nanocarrier with distinctive superiority, polymeric nanoparticles (NPs) have attracted much attention in recent years. However, low biocompatibility and limited exploitation of drug with high efficiency are still the main challenges in RA treatment. To overcome the limitations, we prepared a biocompatible copolymer methoxy-poly(ethylene glycol)-poly(lactide-co-glycolide) (mPEG-PLGA). Moreover, benzoylaconitine (BAC) with superior anti-inflammatory effect was selected as model drug. It was isolated from Aconitum kusnezoffii Reichb and encapsulated into mPEG-PLGA NPs (NP/BAC) to increase the bioavailablity of BAC. The NPs exhibited high cytocompatibility for activated macrophages and well compatibility with red blood cells. Furthermore, the anti-inflammatory property of NP/BAC was testified by substantially inhibiting secretion of pro-inflammatory cytokines. The TNF-α and IL-1β cytokines of NP/BAC group reduced 70 % and 66 % compared with that of activated macrophages. Especially, NP/BAC reduced the overexpression of NF-κB p65 to inhibit NF-κB signaling pathway, which was a critical regulator of inflammatory responses. NP/BAC also showed efficient in vivo anti-inflammatory effect with high ear (69.8 %) and paw (87.1 %) swelling suppressing rate. These results revealed the anti-inflammatory mechanism of NP/BAC and proved it was a suitable DDS to suppress inflammation, providing a promising strategy for RA therapy and research of Aconitum kusnezoffii Reichb.
