High-voltage sodium metal batteries are a highly intriguing battery technology in view of their resource sustainability, cost efficiency, and ultrahigh energy density. However, developing a high-performance electrolyte, compatible with both high-voltage cathodes and highly reactive sodium metal anodes, is extremely challenging. In this work, we delicately formulate a ternary phosphate electrolyte, composing of a cost-effective sodium bis(trifluoromethane sulfonyl) imide salt, a nonflammable triethyl phosphate (TEP) solvent, and a fluoroethylene carbonate (FEC) co-solvent. By rationally tailoring the TEP/FEC ratio, the ternary phosphate electrolyte displays a well-balanced performance, not only enabling highly efficient sodium deposition (an average Coulombic efficiency of 95.7% for Na//Cu cells) but also inheriting the intrinsic anodic stability (≥4.5 V vs Na+/Na) and nonflammability of phosphates. As a consequence, high-voltage Na3V2(PO4)2F3 cathode-based sodium metal cells (Na3V2(PO4)2F3//Na) deliver remarkable cyclic stability (97.9% capacity retention after 300 cycles), which is among the best for Na3V2(PO4)2F3-based batteries. This work may guide the electrolyte design principles and is highly enlightening in developing high energy density sodium-based batteries.Choline is an important factor for regulating human health and is widely present in various foods. In this work, a sensor strategy based on a choline oxidase-integrated copper(II) metal-organic framework with peroxidase-like activity is constructed for one-step cascade detection of choline. The one-step cascade strategy can avoid intermediate product transferring in general multi-step reactions, and the multi-enzyme activities can be well exerted under one condition, thus exhibiting excellent catalytic activity and enhanced stability. In the integrated system, choline is catalyzed by ChOx to produce betaine and H2O2, which eventually got converted to hydroxyl radicals by the peroxidase nanozyme, oxidized the chromogenic substrate ABTS, and produced an observable absorption peak at 420 nm. A new choline detection method was thus established and showed a satisfactory linear relationship at 6-300 μM, which has been used for the choline analysis in milk.Perovskite quantum dots (PQDs) are applicable in light-emitting diodes (LEDs) owing to their color tunability, high color purity, and excellent photoluminescence quantum yield (PLQY) in the solution state. However, a PQD film obtained through nonradiative recombination by concentration quenching and the formation of surface defects exhibited a low PLQY. In this study, we focused on the energy transfer between PQDs with different energy gaps (Eg) to reduce nonradiative recombination in the film state and consequently achieve high device performance. We prepared size-controlled PQDs measuring 10.7 nm (large-size QD; LQD) and 7.9 nm (small-size QD; SQD) with different Eg values and observed a spectral overlap between SQD emission and LQD absorption. To investigate the Förster resonance energy transfer (FRET) from SQDs to LQDs, we prepared SQD-LQD mixed QDs (MQDs). The MQD film enhanced LQD emission and exhibited a higher PLQY (52%) with a longer PL decay time (7.4 ns) than those exhibited by the neat LQD film (38% and 6.2 ns). This energy transfer was determined to be FRET by photoluminescence excitation and PL decay times. Moreover, the external quantum efficiency of an MQD-based LED increased to 15%, indicating that the FRET process can enhance the PLQY of the film and LED efficiency.The interaction of CH4 with cationic copper clusters has been studied with infrared-multiple photon dissociation (IRMPD) spectroscopy. Cun+ (n = 2-4) formed by laser ablation were reacted with CH4. The formed complexes were irradiated with the IR light of the free-electron laser for intracavity experiments (FELICE), and the fragments were mass-analyzed with a reflectron time-of-flight mass spectrometer. The structures of the Cun+-CH4 complexes are assigned on the basis of comparison between the resulting IRMPD spectra to spectra of different isomers calculated with density functional theory (DFT). For all sizes n, the structure found is one with molecularly adsorbed CH4. Only slight deformations of the CH4 molecule have been identified upon adsorption on the clusters, which results in redshifts of the spectroscopic bands. This deformation can be explained by charge transfer from the cluster to the adsorbed methane molecule.
COVID-19 pandemic containment measures have led to changes in various areas of life, including restrictions on health care. Patients with chronic pain may have faced an increased burden during pandemic and the resources of this vulnerable population are unknown. Therefore, a qualitative study was conducted to understand how people with chronic pain have experienced the course of the pandemic.

Twenty semi-structured telephone interviews were conducted six months after the initial lockdown in Germany. The participants were patients with chronic pain who exhibited varying changes in their pain during the first German lockdown, recruited from a German outpatient pain clinic at a Department of Anesthesiology and Intensive Care. The semi-structured interview guidelines were designed to explore how patients with chronic pain experienced their pain during the pandemic, how they coped, and how they experienced pain management during this time. The interview recordings were transcribed verbatim and coded using the qualitative content analysis method.

Four themes emerged from the results differential impact on pain experience, difficulty coping with pain, supportive pain management, and endurance.

During this uncertain time, it was particularly important to maintain pain treatment in order to establish a sense of safety and stability. This underscores the special role of maintaining therapeutic contact during a pandemic and the potentially special role of telemedicine.

Chronic postsurgical pain (CPSP) is common among patients receiving major surgeries. Regorafenib CPSP produces suffering in patients, both physically and mentally. However, the mechanisms underlying CPSP remain elusive. Here, a genome-wide expression profiling of ipsilateral spinal cord dorsal horn (SCDH) was performed to identify potential genes related with CPSP.

A rat skin/muscle incision and retraction (SMIR) model was established to induce CPSP. Immunostaining was used to study glial cell and neuron activation in ipsilateral SCDH of SMIR model rats. RNA sequencing (RNA-Seq), combined with bioinformatics analysis, was undertaken to explore gene expression profiles. qPCR was applied to validate the expression of some representative genes.

The SMIR model rats developed persistent mechanical allodynia in ipsilateral hindpaw for up to 14 days. Ipsilateral SCDH of SMIR rats showed remarkable glial cell and neuron activation. A number of differentially expressed genes (DEGs) were identified in ipsilateral SCDH of SMIR rats by RNA-Seq. qPCR confirmed expression of some representative DEGs. Bioinformatics indicated that chemical synaptic transmission, sensory perception of pain and neuroactive ligand-receptor interaction were predominant functions. We compared our dataset with human pain-related genes and found that several genes exclusively participate in pain modulation and mechanisms.

Our study provided novel understandings of the molecular mechanisms possibly contributing to CPSP. These findings may offer new targets for future treatment of CPSP.

Postherpetic neuralgia (PHN) is a severe complication of herpes zoster (HZ), representing an important burden of disease in the elderly. Electroacupuncture (EA) has become growingly appreciated as a therapy of PHN with the situation that effectiveness of conventional therapy of PHN is less than ideal. Owing to its low price, no side effects, high safety and high patients acceptance, EA has been used in treating PHN more frequently. Therefore, the randomized controlled trial which is to evaluate the effectiveness and safety of EA in patients with PHN and whether EA could be an alternative therapy of medication is needed.

A total of 88 patients with PHN will be recruited from 2 hospitals and randomized assigned to EA group or Medication group in a 11 ratio, utilizing a central randomization system. The trial will involve a 4-week treatment period, and a 4-week follow-up period. All variables will be evaluated at week 0 (baseline), week 2 (treatment), week 4 (treatment), week 8 (follow-up) and week 16 (follow-up). Primary outcomes will be pain intensity. Secondary outcomes will contain quality of life, mood state and sleep quality. All adverse effects will be assessed during the trial.

This study will provide significant evidence that whether EA therapy is effective and safe for patients with PHN and whether EA could be an alternative therapy of medication.

The aims of this study were to identify the prognosis-related risk factors for HCC patients after surgery and to develop a predictive model by analysing the medical records of 152 HCC patients in our hospital.

Univariate Cox regression analysis was applied to identify potential risk factors for HCC patients after surgery and to determine independent prognosis-related risk factors by multivariate analysis. Subsequently, a nomogram model was developed based on all independent factors and was validated by a validation set. Calibration and receiver operating characteristic curves were employed to evaluate the accuracy of the model. Finally, decision curve analyses were used to assess its clinical utility.

The univariate Cox regression analysis indicated that the patient's age, sex, grade, different AJCC TNM stages, vascular invasion, lymphatic infiltration, and tumour size were potential prognostic-related risk factors for HCC patients (p < 0.2), and the findings of multivariate analysis revealed that grsurgery, and a nomogram model built on these predictors exhibited great accuracy and clinical usefulness.
NF-κB signaling is involved in a wide range of biological processes including cell proliferation, cell survival and immunity. Meanwhile, as one of the major oncogenic pathways, its upregulation has been observed in many cancer types. Compared with canonical NF-κB signaling, its non-canonical branch was much less studied in cancerous context.

In this study, we leveraged multi-omics data across multiple platforms to investigate the activity of non-canonical NF-κB signaling in low-grade glioma (LGG) and explore its connection with molecular characteristics of LGG.

We found that non-canonical NF-κB signaling could classify LGG patients into subgroups with significant survival difference. Non-canonical NF-κB-low group enriched with oligodendroglioma featured by CIC mutations and 1p19q co-deletion. On the another hand, LGG in non-canonical NF-κB-high group showed high frequency of EGFR mutations but relatively low frequency of IDH mutations. In addition, LGG in this group reflected immunosuppressive environment characterized by high level of cytotoxic T cell exhaustion and macrophage M2 infiltration.
