Objective:To investigate the effect of mindfulness-based cognitive therapy on the sense of personal control and illness perception of young and middle-aged patients after percutaneous coronary intervention (PCI), so as to provide theoretical and practical guidance for the psychological care of patients after PCI.Methods:A randomized controlled trial was conducted. From January 2022 to December 2023, young and middle-aged patients after PCI admitted to the Department of Cardiology, Qinhuai Medical District, Eastern Theater Command General Hospital of the Chinese People′s Liberation Army were selected as the research subjects by convenient sampling method, patients were divided into the experimental group and the control group by the random number table method. The control group was given routine nursing, and the experimental group was given mindfulness-based cognitive therapy on the basis of routine nursing. The Personal Mastery Scale (PMS), Cardiac Self-Efficacy Questionnaire (CSEQ), and Brief Illness Perception Questionnaire (BIPQ) were used to evaluate personal sense of control, self-efficacy, and illness perception before and after the intervention respectively.Results:A total of 80 young and middle-aged patients after PCI were included. There were 40 cases in the control group, including 25 males and 15 females, aged (49.43 ± 5.55) years old. There were 40 cases in the experimental group, including 19 males and 21 females, aged (49.03 ± 4.19) years old. Before the intervention, there was no statistically significant difference in the PMS, CSEQ and BIPQ scores between the two groups of patients (all P>0.05). After the intervention, the PMS, CSEQ scores of the patients in the experimental group were (23.03 ± 2.54), (45.85 ± 8.16) points respectively, which were higher than (21.95 ± 2.28), (39.05 ± 8.78) points in the control group, the BIPQ score of the patients in the experimental group was(39.63 ± 8.12) points, which was lower the (45.45 ± 8.64) points in the control group, the differences were statistically significant ( t=-2.00, -3.59, 3.11, all P<0.05). Conclusions:Mindfulness-based cognitive therapy can effectively improve the sense of personal control and self-efficacy of young and middle-aged patients after PCI, reduce the sense of threat to the disease.

Objective:The prediction model of postoperative recurrence of ovarian endometriosis cyst(OEM)was constructed to provide a reference for evaluating postoperative recurrence of OEM patients.Methods:The clinical,pathological and follow-up data of 342 patients who underwent the initial laparoscopic ovarian cystectomy for OEM at The Second Hospital of Hebei Medical University from January 1,2017 to October 31,2021 were retro-spectively analyzed.Based on univariate and multivariate Cox regression analysis,the relevant factors affecting OEM recurrence were identified.According to the results of multivariate analysis,a nomogram was drawn.The C index and receiver operating characteristic(ROC)curve were used to test the efficiency of the prediction model.Results:The 2-year recurrence rate of OEM patients was 20.4%and the 5-year recurrence rate was 35.2%.Uni-variate and multivariate Cox regression analysis showed that menstrual cycle(HR 0.916,95%CI 0.860-0.976,P=0.006),delivery≥1(HR 0.376,95%CI 0.171-0.827,P=0.015),CA125≥100 U/ml(HR 1.790,95%CI 1.167-2.746,P=0.008),total cyst diameter≥10 cm(HR 2.254,95%CI 1.318-3.854,P=0.003),and postoperative medications(HR 0.434,95%CI 0.292-0.644,P=0.000)were associated with OEM recurrence and were included in the no-mogram prediction model.The C-index of the nomogram prediction model was 0.710(95%CI 0.665-0.754),and the area under the curve(AUC)of the ROC for OEM patients with recurrence at 2 years after surgery was 0.786 and 0.708 at 5 years.Conclusions:In this study,we developed a nomogram to predict the probability of recur-rence at 2 years and 5 years for OEM patients under 45 years who underwent conservative surgery,which has i-deal predictive performance and helps clinicians to screen high-risk patients,and thus give high-risk OEM patients additional attention and intervention.

This study explores the antiviral effects of Lopinavir on porcine hemagglutinating en-cephalomyelitis virus(PHEV)in vitro and in vivo.Using PHEV-infected N2a cells as an in vitro experimental model,the impact of varying concentrations of Lopinavir on PHEV replication was analyzed through Western blot and qRT-PCR techniques.The results demonstrated that Lopinavir was beneficial to PHEV replication at low-concentration,but as the concentration increased,Lopi-navir began to exert an inhibitory effect,with the most pronounced effect observed at a concentra-tion of 8 μmol/L.PHEV-infected 3-week-old male BALB/c mice were utilized in vivo experi-ments,with Lopinavir(10 mg/kg)administered intragastrically three days post-infection.Follow-ing the onset of illness in the control group,all mice were euthanized,and brain tissues were col-lected for histopathological examination.The findings indicated that Lopinavir significantly reduced the distribution of PHEV and ameliorated the pathological damage in brain tissue,and prolonged the survival time of the mice.In conclusion,Lopinavir exhibits an antiviral effect against PHEV both in vitro and in vivo,offering a theoretical basis for the prevention and treatment of PHEV in-fections in clinical practice.

Cancer immunotherapy has emerged as a promising strategy. However, low response rates and immune-related side effects have plagued immunotherapy. Metallic nanoparticles, utilizing metals as their framework, are gaining prominence in cancer immunotherapy. Metal ions have shown the ability to modulate immune status by activating the cGAS-STING pathway and inducing immunogenic cell death (ICD), thereby enabling multidimensional activation of immunotherapy. Metallic nanoparticles offer significant advantages in cancer immunotherapy, leading to their increasing use in enhancing therapeutic outcomes. In view of the ever-increasing research on metallic nanoparticles, this review presents the construction, characterization, and enhanced cancer immunotherapeutic effects of different types of metal nanosystems from the perspective of the immunoregulatory mechanisms of metal ions. We delve into the current limitations and future directions of metallic nanoparticles in this rapidly evolving field. To the best of our knowledge, this review offers the most up-to-date and systematic analysis of metallic nanoparticles in immunotherapeutic applications. It is anticipated that this review of metallic nanoparticles will inspire a more refined and intelligent design of metallic nanoparticles for future research, paving the way for advancing their clinical applications.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

To establish a double fluorescent RT-LAMP that can distinguish between chicken astro-virus(CAstV)and avian nephritis virus(ANV),two sets of specific primers and probes labeled with fluorescent groups were designed by comparing the conserved sequences of CAstV ORF1b gene and ANV ORF1b gene downloaded from GenBank.The CAstV probe was labeled with CY3 fluorophore at the 3'end and the quencher BHQ2 at the 5'end.The ANV probe was labeled with CY3 fluorophore at the 3'end and the quencher BHQ2 at the 5'end.The reaction system of the method was optimized,and specificity,repeatability,interference,sensitivity,and clinical sample detection were performed.The results were compared with RT-qPCR and RT-PCR to verify the ef-fectiveness of the method.The experimental results showed that the established double fluorescence RT-LAMP method could complete the reaction within 60 min,and the optimal reac-tion temperature was 65 ℃.This method only detects ANV and CAstV,with no cross-reactivity to other common avian pathogens.The minimum detection limit of CAstV was 1.4 ×10 2 copies/μL,and the minimum detection limit of ANV was 1.5×10 2 copies/μL.The interference and reproduc-ibility tests were good.Compared with RT-qPCR,the coincidence rates of CAstV and ANV were 97.97％and 98.85％,respectively.In conclusion,the double fluorescence RT-LAMP method estab-lished in this study has the characteristics of rapidity,accuracy,good specificity,high sensitivity and good reproducibility,which is suitable for clinical diagnosis and provides technical support for the epidemiological investigation of CAstV and ANV.

Objective:To evaluate the safety of neoadjuvant therapy with pembrolizumab combined with 5-fluorouracil (5-FU) and cisplatin in patients with advanced temporal bone squamous cell carcinoma (TBSCC), and its impact on tumor response rate and disease-free survival (DFS).Methods:This prospective, single-arm, open-label clinical study enrolled patients with advanced (Stage Ⅲ/Ⅳ) TBSCC from Sun Yat-sen Memorial Hospital. Patients received 2-3 cycles of neoadjuvant therapy with pembrolizumab, 5-FU, and cisplatin, followed by definitive surgery. Postoperatively, patients received 6 cycles of pembrolizumab combined with radiotherapy. The primary endpoint was the 2-year disease-free survival (DFS) rate. Secondary endpoints included objective response rate (ORR) and safety indicators. Survival analysis was performed using the Kaplan-Meier method. Adverse events (AE) were assessed using the National Cancer Institute′s Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Statistical analyses were conducted using SPSS software, version 22.0.Results:From August 2021 to April 2024, 16 patients with advanced TBSCC were enrolled (13 males and 3 females), with a median age of 54 years and a median follow-up time of 2.32 years. Following neoadjuvant therapy, the objective response rate (ORR) was 64.3% (9/14), and the disease control rate (DCR) was 92.9% (13/14). The 2-year DFS rate was 86.6%. Common treatment-related adverse events (TRAE) included leukopenia (56.3%, 9/16), nausea and vomiting (50.0%, 8/16), diarrhea, oral mucositis, and elevated liver function tests (25.0%, 4/16).
