Abstract
The combination of gene therapy and chemotherapy has showed increased therapeutic efficacy in the treatment of cancers, but it is not well investigated about the actual coordination pattern between therapeutic gene and chemical drug. In this work, p53/BPEI-β-CD/AD-dox complex was fabricated and employed to investigate the interaction manner between p53 and doxorubicin (Dox). Briefly, branched polyethylenimine (BPEI) was conjugated with β-cyclodextrin hydrate (β-CD) to form BPEI-β-CD backbone, and p53 plasmid was condensed by positively charged BPEI via electrostatic interaction, while Dox was first conjugated with adamantine (AD) and then assembled with BPEI-β-CD backbone via the host-guest interaction. It was found that the BPEI-β-CD backbone possessed high endocytosis efficiency but low cytotoxicity. Moreover, p53/BPEI-β-CD/AD-dox complex released Dox and enabled the expression of p53 gene in a sequential manner, and the released Dox and expressed p53 gene showed successive inhibition of the growth of HeLa cells in vitro. With the ability to co-deliver chemical drug and therapeutic gene and exert their inhibitory actions on tumor cell growth in a sequential manner, this DNA/BPEI-β-CD/AD-drug complex via electrostatic interaction and host-guest assembly not only achieved long-term efficacy in inhibiting tumor cell growth but also can be employed as a platform to investigate the coordination pattern between chemical drugs and therapeutic genes for other purposes.

Abstract
The unique ability of cyclodextrins (CDs) to form inclusion complexes can be transmitted to polymeric networks in which CDs are chemically grafted or cross-linked. Combination of CDs and hydrogels in a single material leads to synergic properties: the hydrophilic network enhances biocompatibility and prevents dilution in the physiological medium increasing the stability of the inclusion complexes, while CDs finely tune the mechanical features and the stimuli-responsiveness and provide affinity-based regulation of drug loading and release. Therefore, CD-functionalized materials are opening new perspectives in pharmacotherapy, emerging as advanced delivery systems (DDS) for hydrophobic and hydrophilic drugs to be administered via almost any route. Medical devices (catheters, prosthesis, vascular grafts, bone implants) can also benefit from surface grafting or thermofixation of CDs. The present review focuses on the approaches tested to synthesize nano- to macro-size covalently cross-linked CD networks: i) direct cross-linking through condensation with di- or multifunctional reagents, ii) copolymerization of CD derivatives with acrylic/vinyl monomers, and iii) grafting of CDs to preformed medical devices. Examples of the advantages of having the CDs chemically bound among themselves and to substrates are provided and their applicability in therapeutics discussed.

Abstract
beta-Cyclodextrin (beta-CD) hydrogel was prepared in a strong alkali condition using epichlorohydrin (EPI) as a cross-linker, where the molar ratios of EPI to beta-CD were 8:1, 10:1, and 15:1. In order to endow a pH sensitivity to the hydrogel, naphthaleneacetic acid (NAA) was loaded in the hydrogel by taking advantage of its hydrophobic interaction with the cavities of beta-CD. The releases of blue dextran (a water-soluble dye) from the hydrogels were promoted, as the pHs of the media increased. When the molar ratio of EPI to beta-CD was lower, the degrees of release were higher, and the pH dependency of the release became more prominent. In fact, the swelling ratio of the hydrogels having a lower molar ratio of EPI to beta-CD was higher. The higher swelling ratio would account for the higher degree of release and the marked pH sensitivity.
