Abstract
Rheumatoid arthritis (RA) can lead to joint destruction and deformity, which is a significant cause of the loss of the young and middle-aged labor force. However, the treatment of RA is still filled with challenges. Though dexamethasone, one of the glucocorticoids, is commonly used in the treatment of RA, its clinical use is limited because of the required high-dose and long-term use, unsatisfactory therapeutic effects, and various side-effects. Ultrasound-targeted microbubble destruction (UTMD) can augment the ultrasonic cavitation effects and trigger drug release from targeted nanocarriers in the synovial cavity, which makes it a more effective synergistic treatment strategy for RA. In this work, we aim to utilize the UTMD effect to augment the synergistic therapy of RA by using polyethylene glycol (PEG)-modified folate (FA)-conjugated liposomes (LPs) loaded with dexamethasone sodium phosphate (DexSP) (DexSP@LPs-PEG-FA). The UTMD-mediated DexSP@LPs-PEG-FA for targeted delivery of DexSP including a synergistic ultrasonic cavitation effect and drug therapy were investigated through in vitro RAW264.7 cell experiments and in vivo collagen-induced arthritis SD rat model animal experiments. The results show the DexSP release from targeted liposomes was improved under the UTMD effect. Likewise, the folate-conjugated liposomes displayed targeting association to RAW264.7 cells. Together with the application of ultrasound and microbubbles, liposomes-delivered DexSP potently reduced joints swelling, bone erosion, and inflammation in both joints and serum with a low dose. These results demonstrated that UTMD-mediated folate-conjugated liposomes are not only a promising method for targeted synergistic treatment of RA but also may show high potential for serving as nanomedicines for many other biomedical fields.

Multifunctional-imprinted nanocomposite membranes with thermo-responsive biocompatibility for selective/controllable recognition and separation application.

Abstract
Inspired by the biomimetic modification strategy of dopamine self-polymerization technique, molecularly imprinted nanocomposite membranes (MINCMs) with thermo-responsive rebinding and separation performance were synthesized and evaluated. Herein, the Au/SiO2-based multilevel structure had been successfully obtained onto the polydopamine (pDA) modified membrane surfaces. Afterward, the poly(N-isopropylacrylamide)-based biomolecule-imprinted sites were adequately constructed by developing a photoinitiated atom transfer radical polymerization (pATRP) imprinting strategy using the high-biocompatible ovalbumin (Ova, pI 4.6) as template molecule. Therefore, thermo-responsive 'specific recognition sites' toward Ova were then achieved on the as-prepared MINCMs after the well-designed imprinting process. When the external temperature was set at 37 °C, excellent ovalbumin rebinding capacity (33.26 mg/g), selectivity factor (3.06) and structural stability were obtained. Importantly, as to the controllable biocompatibility research of this work, the bare glass and Ova-bound-MINCMs (the MINCMs were bound with Ova) showed basically the same cell adhesion behaviors and viability, indicating the excellent biocompatibility of the Ova-bound-MINCMs. Additionally, efficient and rapid regulation of cell adhesion/detachment on ovalbumin-bound MINCMs could be still obtained even after 10 cycles of temperature-switch process, which indicated that the as-prepared MINCMs had strong ability to work under high intensity and long continuous operation.

Three-dimensional macroporous wood-based selective separation membranes decorated with well-designed Nd(III)-imprinted domains: A high-efficiency recovery system for rare earth element. J Colloid Interface Sci 2020; 587:703-714.

Abstract
Three-dimensional (3D) basswood materials, for the first time, were successfully used for the construction of rare-earth Nd(III)-imprinted nanocomposite membranes. Herein, polydopamine (PDA)-modified layers could be initially synthesized on basswood surfaces. After the double-bonded modification procedure, the 3D wood-based ionic imprinted membranes (3DW-IIMs) system was finally accomplished by developing a re-modified two-step-temperature free radical polymerization process. The as-design PDA@basswood surface structure was first proposed and applied as imprinting-initiated factors for the preparation of Nd(III)-imprinted sites. Importantly, excellent rebinding capacity (120.87 mg g-1), adsorption kinetics and permselectivity coefficients (more than 10) were achieved successfully. Furthermore, an important research result had also been found that the PDA-modified layers caused significant promotions to the rebinding capacities of the as-prepared 3DW-IIMs, that is to say, more and more Nd(III)-imprinted sites could be synthesized because of the PDA-modified surfaces. The as-obtained selective rebinding and separation results together with the green natural wood-based materials strongly demonstrated that our synthesis methodology of 3DW-IIMs had great potential for applications in various fields of rare earth separation, chemical industry, and environment protection.

Abstract
In spite of the intense efforts in selective separation field, the utilization and preparation of membrane-associated molecularly imprinted membranes with both enhanced rebinding capacities and high permselectivity performance still remain strong challenges. Herein, the bioinspired PDA-modified porous regenerated cellulose membrane (pRCMs) with mineral-coated multilevel structure was first proposed for the preparation of PDA/CaCO3-based imprinted nanocomposite membranes (PCIMs), m-cresol was chosen as the template molecule. Importantly, this bioinspired methodology was redeveloped and optimized to obtain abundant and uniformly distributed CaCO3 nanocomposite on the surfaces of PDA@pRCMs. The as-designed sandwich-like imprinting structure were then constructed on PDA/CaCO3-based surfaces by developing a simple sol-gel imprinting process. Attributing to the design of the uniform CaCO3/PDA@pRCMs surfaces, amount of m-cresol-imprinted sites and permeation selectivity could be both optimized, it was no surprise that more excellent rebinding capacity (97.4 mg g-1), fast adsorption kinetics and high permselectivity coefficients (more than 13) were successfully achieved. Importantly, the whole synthesis process was conducted without complicated procedures and polluting the environment. Finally, the experimental results mentioned above, together with the green synthesis processes strongly demonstrated that our synthesis methodology of PCIMs had great potential for applications in various fields of selective separation, chemical industry, environment, biological medicine and so on.
