ObjectiveTo observe the effect of hyperbaric oxygen therapy (HBOT) combined with repetitive peripheral magnetic stimulation (rPMS) on ankle motor function and balance of stroke patients. MethodsFrom April, 2022 to March, 2023, 96 patients in the First Affiliated Hospital of Bengbu Medical College were randomly divided into control group (n = 32), rPMS group (n = 32) and combined group (n = 32). The control group received conventional rehabilitation; rPMS group received rPMS on the basis of the control group; and the combined group received HBOT on the basis of rPMS group, for two weeks. Before and after treatment, the plantar weight-bearing ratio of the affected side, Berg Balance Scale (BBS), active range of motion (AROM) of ankle dorsiflexion of the affected side, and integrated electromyographic (iEMG) values during maximum isometric contraction of the tibialis anterior and gastrocnemius muscles were measured. ResultsTwo cases dropped out in each group, and 90 cases were finally included, and no adverse events occurred during treatment. Before treatment, there was no significant difference in plantar weight-bearing ratio of the affected side, BBS score, AROM of ankle dorsiflexion of the affected side, and iEMG of tibialis anterior and gastrocnemius among three groups (F < 2.070, P > 0.05). After treatment, all the indicators significantly improved in all the groups (|t| > 27.004, P < 0.001), and they were better in the combined group than in rPMS group and the control group (P < 0.001); except the proportion of plantar weight-bearing on the affected side, the other indicators were better in rPMS group than in the control group (P < 0.001). ConclusionrPMS can promote the recovery of ankle motor function and balance of stroke patients, and the effect combining with HBOT is better.

Objective: Empirical findings confirmed that autistic and schizotypal traits are associated with attentional function as well as include various dimensions. So far, no study has reported which dimension of these traits relates to attentional networks. This study aimed to find out whether there are associations between attentional networks and autistic traits; and between attentional networks and schizotypal traits. Methods: A total of 449 volunteers was included in this study, and autism-spectrum quotient (AQ), schizotypal personality questionnaire (SPQ), and attention network test (ANT) were used to measure autistic traits and schizotypal traits. The three independent attentional networks, including alerting network, orienting network, and executive control network, were also measured. Results: Autistic traits were associated with the orienting network, whereas schizotypal traits were associated with the orienting network and executive control network. Furthermore, attentional networks could be predicted by specific dimensions of autistic and schizotypal traits. AQ-attention switching [0.104 (-1.175– -0.025), p=0.041] and AQ-attention to detail [-0.097 (-0.798– -0.001), p=0.049] were significant predictors of orienting network and gender were significant predictor of executive network (Beta=0.107; 95% CI=-0.476–10.139; p=0.031). Whereas, schizotypal dimension “interpersonal” was a significant predictor of all three attentional networks [Alerting: 0.147 (-0.010–0.861), p=0.045; Orienting: 0.147 (0.018–0.733), p=0.040; Executive: 0.198 (0.215–1.309), p=0.006]. Conclusion This study demonstrated that autistic and schizotypal traits were associated with attentional networks. The specific dimensions of autistic and schizotypal traits could predict attentional networks. Nevertheless, the attentional networks predicted with these two traits were different.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

Alcohol abuse leads to alcoholic liver disease and no effective therapy is currently available. Wuzhi Tablet (WZ), a preparation of extract fromthat is a traditional hepato-protective herb, exerted a significant protective effect against acetaminophen-induced liver injury in our recent studies, but whether WZ can alleviate alcohol-induced toxicity remains unclear. This study aimed to investigate the contribution of WZ to alcohol-induced liver injury by using chronic-binge and acute models of alcohol feeding. The activities of ALT and AST in serum were assessed as well as the level of GSH and the activity of SOD in the liver. The expression of CYP2E1 and proteins in the NRF2-ARE signaling pathway including NRF2, GCLC, GCLM, HO-1 were measured, and the effect of WZ on NRF2 transcriptional activity was determined. We found that both models resulted in liver steatosis accompanied by increased transaminase activities, but that liver injury was significantly attenuated by WZ. WZ administration also inhibited CYP2E1 expression induced by alcohol, and elevated the level of GSH and the activity of SOD in the liver. Moreover, the NRF2-ARE signaling pathway was activated by WZ and the target genes were all upregulated. Furthermore, WZ significantly activated NRF2 transcriptional activity. Collectively, our study demonstrates that WZ protected against alcohol-induced liver injury by reducing oxidative stress and improving antioxidant defense, possibly by activating the NRF2-ARE pathway.

To investigate the cytotoxicity of the homemade peptide cationic liposome CDO14 and its efficacy of RNA interference (RNAi). MTT method was used to determine the cytotoxicity of the liposome to a human lung cancer cell line Luc-A549 that can express luciferase stably. Luciferase siRNA (Luc-siRNA) was transfected into Luc-A549 cells by CDO14. Contents of luciferase in the transfected cells were detected by luminous instrument and contents of total protein in these cells were detected by BCA method. Nude mice were inoculated with Luc-A549 cells in axilla to establish xenograft tumor model. Complexes of Luc-siRNA and the cationic liposomes were injected into the modeling mice via tail vein. Contents of luciferase in the transfected mice were detected by the whole body imaging system. The cytotoxicity of the homemade cationic liposome was similar to that of commercial liposome DOTAP, and lower than that of Lipo2000. The siRNA transfection efficacy mediated by CDO14 was higher than that mediated by DOTAP. The homemade peptide cationic liposome CDO14 is expected to serve as delivery vector in gene therapy because of its low cytotoxicity and high transfection efficiency.
