Abstract
Current management of anesthesia-associated complications falls short in terms of both efficacy and safety. Nanomaterials with versatile properties and unique nano-bio interactions hold substantial promise as therapeutics for addressing these complications. This review conducts a thorough examination of the existing nanotherapeutics and highlights the strategies for developing prospective nanomedicines to mitigate anesthetics-related toxicity. Initially, general, regional, and local anesthesia along with the commonly used anesthetics and related prevalent side effects are introduced. Furthermore, employing nanotechnology to prevent and alleviate the complications of anesthetics is systematically demonstrated from three aspects, that is, developing 1) safe nano-formulization for anesthetics; 2) nano-antidotes to sequester overdosed anesthetics and alter their pharmacokinetics; 3) nanomedicines with pharmacodynamic activities to treat anesthetics toxicity. Finally, the prospects and challenges facing the clinical translation of nanotherapeutics for anesthesia-related complications are discussed. This work provides a comprehensive roadmap for developing effective nanotherapeutics to prevent and mitigate anesthesia-associated toxicity, which can potentially revolutionize the management of anesthesia complications.

Abstract
A magnetic molecularly imprinted polymer (MMIP) was synthesised and tested for an in vivo rheumatoid arthritis (RA) rat model. Magnetite coated with mesoporous silica (Fe2O3@mSi) was used as core for surface imprinting, dopamine was used as monomer and methotrexate (MTX) was loaded directly during polymerisation. The amount of MTX loaded on MMIPs reached 201.165 ± 0.315 µmol/g. Characterisation of the polymers was done via SEM, TEM, and FTIR. The pharmacological effect of the selected MMIP was evaluated in a Complete Freund's Adjuvant (CFA) induced arthritis rat model where a 3D magnet bearing construct was designed for targeted delivery of MMIPs. The parameters evaluated were the change in paw edoema, paw diameter, gait score, and animal's weight. Results revealed a tendency of MMIP to significantly improve the measured parameters which was confirmed with histopathological findings. In conclusion, the improvement in the arthritic signs associated with MMIP treatment compared to free MTX, indicated successful targeting of MMIPs to the site of inflammation.

Abstract
Coptisine (Cop) exerts a neuroprotective effect on central nervous system disease, particularly ischemic stroke. However, its protective mechanism is still unclear. This study aimed to investigate the protective effect of Cop on cerebral ischemia-reperfusion (IR) rats with a middle cerebral artery occlusion model by integrating a gas chromatography-mass spectrometry (GC-MS)-based metabolomics approach with biochemical assessment. Our results showed that Cop could improve neurobehavioral function and decrease the ischemia size in IR rats. In addition, Cop was found to decrease inflammatory mediators (e.g., prostaglandin D2 (PGD2) and tumor necrosis factor-α (TNF-α) and attenuate oxidative stress response (e.g., increase the superoxide dismutase (SOD) expression and decrease 8-iso-PGF2α level). Furthermore, the GC-MS-based cerebrospinal fluid (CSF) metabolomics analysis indicated that Cop influenced the level of glycine, 2,3,4-trihydroxybutyric acid, oleic acid, glycerol, and ribose during IR injury. Cop exhibited a good neuroprotective effect against cerebral IR injury and metabolic alterations, which might be mediated through its antioxidant and anti-inflammatory properties.

Abstract
Stroke is a common cerebrovascular disease that can interrupt local blood flow in the brain, causing neuronal damage or even death, resulting in varying degrees of neurological dysfunction. Neuroplasticity is an important neurological function that helps neurons reorganize and regain function after injury. After cerebral ischemia, neuroplasticity changes are critical factors for restoring brain function. An enriched environment promotes increased neuroplasticity, thereby aiding stroke recovery. In this review, we discuss the positive effects of the enriched environment on neuroplasticity after cerebral ischemia, including synaptic plasticity, neurogenesis, and angiogenesis. In addition, we also introduce some studies on the clinical application of enriched environments in the rehabilitation of post-stroke patients, hoping that they can provide some inspiration for doctors and therapists looking for new approaches to stroke rehabilitation.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 303:115961.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huanglian Jiedu Decoction (HLJDD) is a traditional heat-dissipating and detoxicating prescription used in Chinese medicine and has been extensively applied in the clinical treatment of ischemic stroke. Preliminary research confirmed that HLJDD exerts a neuroprotective effect on brain tissue injury caused by cerebral ischemia by promoting angiogenesis. However, the components of HLJDD responsible for its medicinal activity in ischemic injury remain unclear. AIM OF THE STUDY The aim of this study was to identify the active components of HLJDD that could promote angiogenesis and investigate its underlying mechanism, as well as Hypoxia-inducible factor-1α (HIF-1α)/Vascular endothelial growth factor (VEGF) signalings in human umbilical vein endothelial cells (HUVECs). MATERIALS AND METHODS The specific binding components of HLJDD with HUVECs were isolated and identified through a combination of live cell biospecific extraction, solid-phase extraction, and ultra performance liquid chromatography (UPLC)-Orbitrap Fusion Tribrid mass spectrometry (MS). Their pharmacological activity against oxygen-glucose deprivation-reperfusion (OGD/R) injury and in vitro pro-angiogenesis was validated using Cell Counting Kit-8 (CCK-8) and tube formation analysis, respectively. Finally, we explored the effect of active ingredients on the expression levels of HIF-1α and VEGF using enzyme-linked immunosorbent assay. Molecular docking was used to predict the potential binding of six active components to phosphoinositide 3-kinase (PI3K), serine/threonine-specific protein kinase (AKT) and Von Hippel-Lindau (VHL) proteins, which are involved in the regulation of HIF-1α and are highly associated with angiogenesis. RESULTS A total of 13 HUVECs-specific HLJDD components were identified, and 10 of them were shown to protect against OGD/R injury. We were the first to demonstrate that two of these components have a protective role in OGD/R-induced HUVECs injury. Additionally, seven of these 10 components exhibited angiogenesis-promoting activity, and two of these components were shown, for the first time, to promote angiogenesis in HUVECs. These effects might occur through the HIF-1α/VEGF pathway. Molecular docking results showed that all six active ingredients could stably bind to PI3K and AKT proteins, suggesting that these two proteins may be potential targets for six active ingredients. CONCLUSIONS The approach employed in this study effectively identified proangiogenic components in HLJDD that might act via PI3K/AKT/HIF-1α/VEGF pathways and other mechanisms involved in angiogenesis. In conclusion, this study was the first to demonstrate four compounds with new bioactivities and could also provide insight into the isolation and discovery of new bioactive compounds existing in Chinese medicine with potential clinical value.

Abstract
In this study, a ligand fishing technique based on magnetic mesoporous silicon was established and used to screen α-glucosidase inhibitors from Pueraria lobata. To clarify quantity-activity relationships in a holistic view, the knock-out/knock-in technology was used to analyse the interactions of several active constituents in P. lobata. Magnetic mesoporous silicon with a large specific surface area and better biocompatibility was synthesised. Subsequently, α-glucosidase was immobilised on -NH2-modified magnetic mesoporous silicon, and the compounds in the crude extract of P. lobata were screened across enzyme binding. The structures of the ligands were elucidated using UPLC-Q-TOF-MS/MS, and their activities were verified by knock-out/knock-in experiments and molecular docking. Daidzein and puerarin showed α-glucosidase inhibitory activities with an IC50 of 0.088 ± 0.003 mg mL-1 and 0.414 ± 0.005 mg mL-1, respectively. Among them, puerarin, which accounted for more than 40% of the total content, showed synergistic effects with other components and was the main contributor to the α-glucosidase inhibitory activity of P. lobata.

Abstract
Background Disruption of the postsynaptic density protein-95 (PSD95)—neuronal nitric oxide synthase (nNOS) coupling is an effective way to treat ischemic stroke, however, it still faces some challenges, especially lack of satisfactory PSD95-nNOS uncouplers and the efficient high throughput screening model to discover them. Results Herein, the multifunctional metal–organic framework (MMOF) nanoparticles as a new screening system were innovatively fabricated via layer-by-layer self-assembly in which His-tagged nNOS was selectively immobilized on the surface of magnetic MOF, and then PSD95 with green fluorescent protein (GFP-PSD95) was specifically bound on it. It was found that MMOF nanoparticles not only exhibited the superior performances including the high loading efficiency, reusability, and anti-interference ability, but also possessed the good fluorescent sensitivity to detect the coupled GFP-PSD95. After MMOF nanoparticles interacted with the uncouplers, they would be rapidly separated from uncoupled GFP-PSD95 by magnet, and the fluorescent intensities could be determined to assay the uncoupling efficiency at high throughput level. Conclusions In conclusion, MMOF nanoparticles were successfully fabricated and applied to screen the natural actives as potential PSD95-nNOS uncouplers. Taken together, our newly developed method provided a new material as a platform for efficiently discovering PSD95-nNOS uncouplers for stoke treatment. Graphical Abstract ![]()

Abstract
Novel and highly selective molecularly imprinted polymers based on the surface of metal–organic frameworks, NH2-MIL-101(Cr) (MIL@MIPS), were successfully fabricated to capture neuronal nitric oxide synthase–postsynaptic density protein-95 (nNOS–PSD-95) uncouplers from Sanhuang Xiexin Decoction (SXD) for stroke treatment. The resultant polymers were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, and X-ray diffraction. The performance tests revealed that MIL@MIPs had a large binding capacity, fast kinetics, and excellent selectivity. Then the obtained polymers were satisfactorily applied to solid-phase extraction coupled with high-performance liquid chromatography to selectively capture nNOS–PSD-95 uncouplers from SXD. Furthermore, the biological activities of components obtained from SXD were evaluated in vivo and in vitro. As a consequence, the components showed a potent neuroprotective effect from the MTS assay and uncoupling activity from the co-immunoprecipitation experiment. In addition, the anti-ischemic stroke assay in vivo was further investigated to determine the effect of reducing infarct size and ameliorating neurological deficit by the active components. Therefore, this present study contributes a valuable new method and new tendency to selectively capture active components for stroke treatment from SXD and other natural medicines. Novel MIL@MIPs were prepared to rapidly capture nNOS–PSD-95 uncouplers from Sanhuang Xiexin decoction, coupled with SPE and HPLC.![]()
