Polymer electrolytes incorporated with fillers possess immense potential for constructing the fast and selective Li conduction. However, the inhomogeneous distribution of the fillers usually deteriorates the microdomain consistency of the electrolytes, resulting in uneven Li flux, and unstable electrode-electrolyte interfaces. Herein, we formulate a solution-process chemistry to in situ construct gel polymer electrolytes (GPEs) with well-dispersed metal-organic frameworks (MOFs), leading to a uniform microdomain structure.

Materials And Methods: A retrospective study was conducted on 396 patients who underwent UAE (n = 153) or LM (n = 243) treatment from April 2010 to September 2019. After 1:1 propensity score matching (PSM), a comparative analysis was conducted on surgical trauma magnitude, postoperative recovery time, improvement in associated symptoms and quality of life, surgical adverse events, recurrence rates, and further interventions.
Anticancer drugs used for systemic chemotherapy often exhibit off-target toxicity and uncontrolled drug release due to their lack of targeting. To improve the bioavailability of drugs and reduce side effects, we have developed a mixed micelle of nanomedicine composed of two prodrugs with surface modified monoclonal antibody for cancer therapy. In this system, Nimotuzumab was used as targeting ligands of the mixed micelles (named as DCMMs) that is composed of polymer-doxorubicin prodrug (abbreviated as PEG-b-P(GMA-ss-DOX)) and maleimide polyethylene glycol-chlorin e6 (abbreviated as Mal-PEG-Ce6).

Compared with non-cross-linked micelles, SCMs exhibit superior structural stability. At the same time, the introduction of an environmentally sensitive crosslinker into a drug delivery system allows SCMs to respond to single or multiple stimuli in the tumor microenvironment, which can minimize drug leakage during the blood circulation process.

Of the similar concept, targeting cancer cell membrane using membrane active peptides is a hopeful therapeutic modality but had long been hindered from in vivo application. Here we report an enabling strategy of pre-opsonizing a membrane penetrating Ir-complexed octa-arginine peptide (iPep) with serum albumin via intrinsic amphipathicity-driven bimodal interactions into nanoparticles (NP).

Herein, we present an effective strategy to treat HCC using magnetic hyperthermia therapy (MHT)-enhanced cancer immunotherapy combined with transcatheter arterial embolization (TAE). Uniform liquid metal microspheres (LM MSs) obtained by microfluidic technology with powerful eddy-thermal effects could be used as both MHT and TAE agents for effective cancer therapy.

Antibody-drug conjugates (ADCs) are a class of tumor cell-targeting drugs that have developed rapidly in recent years. From the perspective of further improving ADC targeting and developing natural macromolecules as drug carriers, it is still challenging and necessary to try new targeted drug delivery modalities. In this study, we have developed an antibody-modified prodrug nanoparticle based on biomacromolecule dextran (DEX) to delivery antitumour drug doxorubicin (DOX).

In order to develop multifunctional hydrogel dressings with appropriate biological activity to accelerate wound healing and obtain better clinical therapeutic effects, herein we report a hybrid system based on drug loaded mesoporous silica and injectable polymer hydrogels mixed with hypoglycemic drug metformin (Met) as a dressing for diabetic wounds. Firstly, a copolymer with the phenylboronic acid group in the side group, poly(acrylamide--dimethylaminopropylacrylamide--methacrylamidophenylboronic acid) (abbreviated as PB), was prepared.

Since TAMs are mainly composed of M2-type macrophages, they have a promoting effect on tumor growth, invasion, and metastasis. M2-type macrophages contain a specific receptor CD163 on their surface, providing a prerequisite for active targeting to TAMs.

In this report, we evaluated changes in the tumor immune microenvironment (TIME) in distant tumor tissues after Cryo and investigated the immunosuppressive mechanisms that limit the efficacy of Cryo.
Methods: Bilateral mammary tumor models were established in mice, and we first observed the dynamic changes in immune cells and cytokines at different time points after Cryo.
To overcome the limitation of conventional nanodrugs in tumor targeting efficiency, coupling targeting ligands to polymeric nanoparticles can enhance the specific binding of nanodrugs to tumors. Cyclo(Arg-Gly-Asp-d-Phe-Lys) (abbreviated as c(RGDfK)) peptide has been widely adopted due to its high affinity to the tumor marker αβ integrin receptor. In this study, we develop a cRGD peptide-conjugated camptothecin (CPT) prodrug, which enables self-assembly of nanoparticles for precise targeting and enrichment in tumor tissue.

Electrochemo-mechanical failure of Ni-rich cathodes leads to rapid performance degradation, and thus hinders their practical implementation in all-solid-state lithium batteries (ASSLBs). To solve this problem, herein, we propose a bifunctional chemomechanics strategy by protecting polycrystalline LiNiCoMnO (NCM) cathodes using a high-mechanical-strength fast ionic conductor LiZr(PO) (LZP) coating layer. The coating layer's synergistic effect between mechanical strength and electrochemical stability is studied in LiPSCl (LPSCl)-based ASSLBs for the first time.

A routine treatment combining surgical debridement with anti-infection therapy is widely used for treating DUs in the clinic, but hardly offers a satisfying wound healing outcome. It is known that a long-term antibiotic treatment may also lead to the drug resistance of pathogens.

First, a polyphosphoester-based diblock copolymer (PBYP--Gluc)--PEEP was prepared via ring-opening copolymerization (ROP) and the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) in which PBYP and PEEP represent the polymer segments from 2-(but-3-yn-1-yloxy)-2-oxo-1,3,2-dioxaphospholane and 2-ethoxy-2-oxo-1,3,2-dioxaphospholane, respectively, and Gluc comes from 2-azidoethyl-β-d-glucopyranoside (Gluc-N) that grafted with PBYP. The structure and molecular weight of the copolymer were characterized by H NMR, P NMR, GPC, FT-IR, and UV-vis measurements.

The space charge layer (SCL) is generally considered one of the origins of the sluggish interfacial lithium-ion transport in all-solid-state lithium-ion batteries (ASSLIBs). However, in-situ visualization of the SCL effect on the interfacial lithium-ion transport in sulfide-based ASSLIBs is still a great challenge. Here, we directly observe the electrode/electrolyte interface lithium-ion accumulation resulting from the SCL by investigating the net-charge-density distribution across the high-voltage LiCoO/argyrodite LiPSCl interface using the in-situ differential phase contrast scanning transmission electron microscopy (DPC-STEM) technique.
