Background:
Diabetic pain patients have increased pain at night. Exosomes can relieve neuropathic pain. This study aimed to investigate the efficacy of exosome administration at different time points in relieving diabetic neuropathic pain (DNP) in rats.
Methods:
M2 macrophages from bone marrow were induced in mice and exosomes were extracted. A diabetic rat model was induced using streptozotocin, with the mechanical withdrawal threshold (MWT) of the rats beingmeasured at ≤ 80% of the basal value after 14 days, indicating successful construction of the DNP rat model.Exosomes were administered on three consecutive days at ZT0 (zeitgeber time) and ZT12. Parameters including blood glucose levels, body weight, MWT, and thermal withdrawal latency (TWL) were assessed in the rats. The lumbar spinal cord of rats was examined on days 21 and 28 to measure inflammatory factors and observe the expression of M1 and M2 microglia. Furthermore, microglia were exposed to lipopolysaccharide (LPS) and LPS + exosomes in a controlled in vitro setting to assess alterations in microglia phenotype involving the NF-kB p65 andIKBα inflammatory signaling pathways.
Results:
The findings revealed that administration of exosomes during the rat resting period at ZT12 resulted in increased MWT and TWL, as well as a shift in microglia polarization towards the M2 phenotype. In vitro analysis indicated that exosomes influenced microglia polarization and suppressed the phosphorylation of NF-kB p65 andIKBα.
Conclusions
Temporal therapy with exosomes effectively reduces pain in DNP rats by polarizing microglia andaffecting NF-kB p65 and IKBα signaling pathways.

Aldehyde oxidase (AOX) is a molybdoenzyme that is primarily expressed in the liver and is involved in the metabolism of drugs and other xenobiotics. AOX-mediated metabolism can result in unexpected outcomes, such as the production of toxic metabolites and high metabolic clearance, which can lead to the clinical failure of novel therapeutic agents. Computational models can assist medicinal chemists in rapidly evaluating the AOX metabolic risk of compounds during the early phases of drug discovery and provide valuable clues for manipulating AOX-mediated metabolism liability. In this study, we developed a novel graph neural network called AOMP for predicting AOX-mediated metabolism. AOMP integrated the tasks of metabolic substrate/non-substrate classification and metabolic site prediction, while utilizing transfer learning from 13C nuclear magnetic resonance data to enhance its performance on both tasks. AOMP significantly outperformed the benchmark methods in both cross-validation and external testing. Using AOMP, we systematically assessed the AOX-mediated metabolism of common fragments in kinase inhibitors and successfully identified four new scaffolds with AOX metabolism liability, which were validated through in vitro experiments. Furthermore, for the convenience of the community, we established the first online service for AOX metabolism prediction based on AOMP, which is freely available at https://aomp.alphama.com.cn.

A GC-LSTM model is proposed based on the characteristics of global optimization of genetic algorithm.The model automatically and iteratively searches the optimal hyper-parameter configuration of the C-LSTM model through the genetic algorithm of a specific genetic strategy,and it is configured using the genetic iteration results and validated on the MIT-BIH arrhythmia database according to the classification criteria of the Association for the Advancement of Medical Instrumentation.The testing shows that the classification accuracy,sensitivity,accuracy and F1 value of GC-LSTM model are 99.37%,95.62%,95.17%and 95.39%,respectively,higher than those of the manually established model,and it is also advantageous over the existing mainstream methods.Experimental results demonstrate that the proposed method can achieve better classification performance while avoiding a large number of experimental parameters.

Objective To evaluate the effect of pacing in different parts of the ventricle on left ven-tricular mechanical asynchrony using myocardial metabolic imaging.Methods A total of 56 elderly patients undergoing permanent pacemaker implantation in our hospital from January to November 2023 were recruited and randomly divided into left bundle branch pacing(LBBAP)group and right ventricular pacing(RVP)group,with 28 patients in each group.Another 28 elderly patients who did not undergo pacemaker implantation surgery were selected as the control group.Within 1 week after pacemaker implantation,18F fluorodeoxyglucose(18F-FDG)positron emission tomo-graphy(PET)/CT myocardial metabolism imaging was performed to analyze PET myocardial metabolism images and evaluate left ventricular mechanical synchrony.Results The LVEF was significantly higher in the control group than the LBBAP group and RVP group[(67.68±9.61)%vs(62.71±11.33)%vs(57.36±16.07)%,P=0.012],but no such difference was seen between the LBBAP group and the RVAP group(P>0.05).The LBBAP group had obviously lower pat-tern standard deviation(PSD),phase histogram bandwidth(PHBW),entropy,summed motion score(SMS),summed thickening score(STS),extent of abnormal motion(Mot Ext)and thicken-ing extent(Thk Ext)when compared with the RVP group(P<0.01).There were no statistical significant differences in the terms of PSD,PHBW,Entropy,SMS,STS,Mot Ext,and Thk Ext between the LBBAP group and the control group(P>0.05).Conclusion 18F-FDG PET/CT myo-cardial metabolic imaging can be used to evaluate left ventricular mechanical synchrony in pacing different parts of the ventricle,and LBBAP can obtain better left ventricular synchrony parame-ters than RVP,similar to the control group.
