Objective To explore the influences of transcranial direct current stimulation(tDCS)in combination with cognitive-motor dual task training(CMDT)on memory and executive function in patients suffering from post-stroke cognitive impairment.Methods A total of 75 stroke patients were randomly divided into the tDCS group,the CMDT group and the combined group,each consisting of 25 cases.All patients in the three groups received routine rehabilitation treatment.The tDCS group underwent tDCS stimulation of dorsolateral prefrontal lobe(DLPFC)of the region,the CMDT group received CMDT and the combined group received CMDT on the basis of tDCS treatment.The fourth edition of the Wechsler Memory Scale(WMS-IV),Wisconsin Card Test(WCST),Montreal Cognitive Assessment(MoCA)and Modified Barthel Index(MBI)were used to evaluate the overall cognitive function,memory,executive function,and daily living ability of the patients before and 4 weeks after treatment,respectively.Results Before treatment,there were no significant differences in the evaluation indices between the three groups(P＞0.05).After 4 weeks of treatment,the scores of WCST,WMS-IV,MoCA and MBI in the three groups were improved compared with those before the treatment(P＜0.05),and the combined group was significantly superior to the tDCS group and the CMDT group(P＜0.05).Conclusion The combination of tDCS and CMDT can improve the cognitive function after stroke,and at the same time exert a synergistic effect on memory and executive function.

Objective:To investigate the characteristics of visual and auditory sustained attention and sex differences in pupils of different grades.Method:Totally 231 students from grades 1 to 6 participated in this stud-y.The development and sex differences of sustained attention were measured by average reaction times,coefficients of variation for reaction times,omission error rates and commission error rates in visual and auditory two-choice re-action time(CRT)tasks.Result:The students in grade 5 had significantly slower visual average reaction times and coefficients of variation for reaction times(P＜0.001 or P＜0.05)than those in grade 3.The students in grade 5 had significantly lower auditory average reaction times,coefficients of variation for reaction times,omission error rates and commission error rates(P＜0.001 or P＜0.01)than those in grade 1.There was no significant sex differ-ences in visual or auditory average reaction times,coefficients of variation for reaction times or omission error rates(Ps＞0.05).Conclusion:There would be age differences in characteristics of both visual and auditory sustained at-tention in pupils,and may be no sex difference in visual or auditory sustained attention.

Colorectal cancer is the third leading cause of cancer-related mortality worldwide.Hepatic resection is the standard treatment for colorectal cancer liver metastasis.Microwave ablation(MWA),as a minimally invasive therapeutic approach,offers an alternative treatment option for these patients.But the clinical efficacy of hepatic resection and MWA in treating colorectal cancer liver metastasis patients is still inconclusive.Literatures were retrieved on comparative studies about the treatment of colorectal cancer liver metastasis with hepatic resection and MWA from multiple databases,including sinoMed,PubMed,Web of Science,EMBASE,CNKI,Wanfang,etc.The cutoffdate of retrieval was September 2024.Finally,a total of 13 studies comprising 2 057 patients,were included in this study.The papers were assessed using the Newcastle-Ottawa Scale and Jadad Scale.All included studies were of high quality.Data extraction focused on postoperative complications,length of hospital stay,surgical duration,hospitalization costs,and patient survival outcomes,including overall survival(OS)and disease-free survival(DFS).A meta-analysis was performed using Review Manager 5.4 software.There were no significant differences in OS(HR=1.03,95%CI:0.85-1.25,P=0.77)and DFS(HR=1.27,95%CI:0.94-1.71,P=0.13)between the MWA group and the hepatic resection group.In the subgroup analysis of patients with≤5 liver metastases and size of metastases≤3 cm,there were no statistically significant differences in OS and DFS between the MWA group and the hepatic resection group.The MWA group exhibited shorter hospital stay,reduced hospitalization costs,decreased surgical duration,less intraoperative blood loss,and lower incidence of complications compared to the hepatic resection group(P＜0.05).Therefore,for patients with colorectal liver metastases characterized by a number of liver metastases≤5 and size of metastases≤3 cm,MWA serves as an effective alternative to hepatic resection,with a lower morbidity associated with treatment.Further validation of these findings is warranted through additional randomized controlled trials and cohort studies.The registration number of this Meta-analysis on the PROSPERO platform is CRD42024610278.

Bow hunter's syndrome,also referred to as rotational vertebral artery occlusion syndrome,is a rare etiological factor of posterior circulation infarction.This article reported a case of a young male patient who experienced recurrent posterior circulation infarctions caused by bilateral bow hunter's syndrome.Carotid ultrasonography confirmed a marked reduction in blood flow velocity in both vertebral arteries during neck rotation.High-resolution MR angiography and CT angiography of the head and neck revealed dissection involving the V3 segment of the left vertebral artery.The findings suggested that bow hunter's syndrome may be associated with thrombus formation secondary to repetitive mechanical compression of the vertebral artery intima,which could potentially lead to arterial embolism and subsequent cerebral infarction.This paper presents the patient's diagnostic and therapeutic course and includes a review of relevant literature aimed to enhance clinical awareness and understanding of this uncommon condition.

The specific mechanisms of interferon regulatory factor 8(IRF8)in porcine intestinal in-nate immunity and resistance to enteric virus infection remain to be elucidated.To investigate the immunoregulatory role of IRF8,establishing an IRF8 gene knockout porcine intestinal epithelial cell(IPEC-J2)monoclonal cell line is of significant importance.This study initially aimed to obtain recombinant adeno-associated virus rAAV-sgIRF8-eGFP capable of knocking out the IRF8 gene through co-transfection of HEK-293T cells with three plasmids.Subsequently,IPEC-J2 cells were infected with the virus,and those expressing eGFP were selected by flow cytometry and cultured to form monoclonal cell lines.These cell lines were then identified by Sanger sequencing and West-ern blot techniques.Lastly,qPCR analysis was used to measure the expression levels of interferon factors IFN-α,IFN-β,IFN-γ and IFN-λ,providing preliminary insights into the impact of IRF8 gene knockout on IPEC-J2 cell immunity.The results demonstrated successful generation of rAAV-sgIRF8-eGFP,which successfully infected IPEC-J2 cells leading to eGFP fluorescence.Flow cytometry followed by cell culture led to the establishment of two monoclonal cell lines,IRF8-KO1 and IRF8-KO3.Sanger sequencing revealed a five-base deletion in IRF8-KO1 and a seven-base dele-tion in IRF8-KO3.Western blot confirmed the absence of IRF8 protein expression in IRF8-KO1,making it an ideal candidate monoclonal cell line.qPCR analysis of interferon factors indicated sig-nificant decrease in IFN-γ(P＜0.05)and IFN-λ(P＜0.01)transcription level in IRF8-knockout cells,while the transcription levels of IFN-α and IFN-β remained relatively unchanged.This study successfully established an IRF8 gene knockout IPEC-J2 monoclonal cell line,providing a founda-tion for further research on IRF8-related porcine intestinal immune regulation and mechanisms of intestinal virus infection.

Objective:To investigate the regulatory role of the tumor suppressor gene ARID1A(AT-rich interaction domain 1A)in the proliferation of lung adenocarcinoma(LUAD)cells and its molecular mechanism associated with the protein kinase B(AKT)signaling pathway.Methods:Stable ARID1A-overexpressing A549/H1299 cell models were constructed via lentiviral transfection,with transfection efficiency validated by RT-PCR and Western blot.Cell viability was assessed using the CCK-8 assay,proliferation rate was evaluated using EdU staining,and migration capacity was analyzed by scratch assay.Cell death was evaluated through Calcein/PI live/dead staining and trypan blue exclusion.The phosphorylation level of AKT(p-AKT/AKT ratio)was detected by Western blot.The role of AKT in proliferation regulation was further validated by treating overexpressing cells with the AKT inhibitor MK-2206(1 μmol/L).Results:ARID1A overexpression significantly inhibited the proliferation and migration of A549/H1299 cells while upregulating p-AKT levels.MK-2206 treatment abolished the inhibitory effects of ARID1A overexpression on proliferation.Cell death assays demonstrated no significant impact of ARID1A overexpression on LUAD cell mortality.Conclusion:ARID1A specifically suppresses LUAD cell proliferation and migration by activating the AKT signaling pathway,suggesting that targeting AKT may provide a potential therapeutic strategy for LUAD patients with ARID1A deficiency.

Purpose To explore the clinicopathological features and potential clinical value of marginal zone lym-phoma(MZL)derived from T-bet positive memory B cell.Methods Clinical data of 67 cases of MZL were collected.Hematoxylin-eosin,immunohistochemistry,and multiple immunofluorescence stains,B cell receptor high throughput sequencing technology were used to study the histology,immunophenotype,and immunoglobulin heavy chain variable gene(IGHV)repertoire.Results T-bet was expressed in some MZL patients(34/67,50.75％),which was correla-ted with clinicopathological characteristics such as gender,clinical stage,and Ki67 proliferation index(P＜0.05),and also the progression-free survival was poor(P=0.012 2).T-bet positivity was a risk factor affecting the progres-sion of MZL.Microscopically,T-bet positive MZL frequently presented T-bet positive tumor B cells surrounded follicu-lar germinal center,"MALT ball"-type lymphoepithelial lesions,and IgG positive neoplastic plasma cells(P＜0.05).T-bet had no biased influence on the VH gene usage(P＞0.05).The common VH families were IGHV4 and IGHV3,and the segments were IGHV4-34 and IGHV3-30.The positivity of T-bet was associated with somatic hypermutation(SHM)state(P=0.014 9).The SHM was mainly in the range of 2％-4.9％in T-bet positive MZL,while in T-bet negative MZL the SHM was mostly greater than 5％.The VH gene usage was not correlated with the clinicopathological features of patients(P＞0.05).IGHV4 was correlated with progression-free survival in T-bet positive MZL(P=0.038 2).Conclusion The expression of T-bet in MZL is closely related to the clinicopathological features such as histology,plasma cell immunophenotype and IGHV gene repertoire,and the prognosis of patients is poor,which may be a potential molecular marker affecting the progression of MZL.

Objective:To analyze the current status and related factors of occupational burnout among immunization program staff in Dezhou City in 2025.Methods:From February to March 2025, 1 209 healthcare workers engaged in immunization programs in all disease prevention and control centers (CDCs), vaccination clinics and obstetrics vaccination rooms within the jurisdiction of Dezhou City were enrolled in this study. Basic information was collected via questionnaires. The Maslach Burnout Inventory-General Survey (MBI-GS) was used to assess occupational burnout status across three dimensions: emotional exhaustion, depersonalization and low personal achievement, with severity graded by scores. Multivariate logistic regression models were adopted to analyze the related factors of occupational burnout.Results:Among 1 209 participants, 986 (81.56%) were female and 513 (42.43%) were aged ≥40 years old. About 91 (7.53%) worked in CDCs, 970 (80.23%) in vaccination clinics and 148 (12.24%) in obstetric units. The detection rate of occupational burnout was 83.87% (1 014/1 209), with mild-to-moderate and severe occupational burnout rates of 16.38% (198/1 209) and 67.49% (816/1 209), respectively. Multivariate logistic regression model showed that compared with those who had no intention of resigning, those who frequently had turnover intention ( OR=10.225, 95% CI: 4.093-25.543) had a higher risk of experiencing occupational burnout. Compared with those who slept for more than seven hours a day, those who slept for less than six hours a day ( OR=4.266, 95% CI: 1.773-10.266) and those who slept for 6-7 hours ( OR=1.543, 95% CI: 1.100-2.164) had a higher risk of developing occupational burnout. Conclusion:The detection rate of occupational burnout among immunization program staff in Dezhou City is relatively high, significantly related to frequent turnover intention and insufficient sleep.
