OBJECTIVE: To observe the effect of electroacupuncture combined with enhanced recovery after surgery (ERAS) protocol on promoting intestinal function in patients after gastric cancer surgery. METHODS: Forty-four patients who underwent radical gastrectomy for gastric cancer were randomly divided into an experimental group (22 cases, 3 cases were excluded) and a control group (22 cases, 4 cases were excluded). Both groups received treatment under ERAS protocol, the experimental group was given electroacupuncture at bilateral Neiguan (PC6), Hegu (LI4), Zusanli (ST36) and Quchi (LI11), disperse-dense wave was selected, with frequency of 2 Hz/100 Hz. The control group received placebo electroacupuncture intervention, with the same acupoints as the experimental group, electrode pads were placed on the acupoints without electrical stimulation. Each session lasted 30 min, starting from 1 h after surgery, once every 24 h, until the patient resumed anal flatus. The intestinal sound rate of both groups was observed 24 h before surgery and 24, 48 h after surgery. The bowel sound recovery time (BSRT), time to first anal flatus, time to first defecation, and tolerance to oral enteral nutrition suspension were compared between the two groups. The levels of serum C-reactive protein (CRP), interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured 24 h before surgery and 24 h after surgery in both groups. RESULTS: The intestinal sound rate 24 h after surgery was decreased compared with that 24 h before surgery in the two groups (P<0.05), the intestinal sound rate 24, 48 h after surgery in the experimental group was higher than that in the control group (P<0.05). The BSRT in the experimental group was earlier than that in the control group (P<0.05) .The levels of serum CRP, IL-6, IL-10 24 h after surgery in the experimental group were higher than those 24 h before surgery (P<0.05), while the levels of serum CRP, IL-4, IL-6, IL-10, IFN-γ in the control group were higher than those 24 h before surgery (P<0.05); the levels of serum CRP、IL-4、IFN-γ 24 h after surgery in the experimental group were lower than those in the control group (P<0.05) .The tolerance rate of oral enteral nutrition suspension in the experimental group was 84.2% (16/19), which was higher than 50.0% (9/18) in the control group (P<0.05). CONCLUSION Electroacupuncture combined with ERAS protocol can improve the intestinal motility, shorten the BSRT, enhance the tolerance of oral intake, and reduce inflammatory response in patients after gastric cancer surgery.

Objective:To explore the chain mediation role of career development planning and career success in the relationship between nurses' professional values and occupational embeddedness.Methods:From February to March 2024, a convenience sampling method was used to select 763 nurses from ClassⅢ Grade A hospitals in Wenzhou as research subjects. Data were collected using a General Information Questionnaire, the Occupational Embeddedness Scale for Nurses (OESN), the Nursing Professional Values Scale-Revised (NPVS-R), the Nurses' Career Planning Questionnaire (NCPQ), and the Career Success Scale for Nurses (CSSN). Pearson correlation analysis was performed to examine the correlations among the scores of OESN, NPVS-R, NCPQ, and CSSN. The AMOS 21.0 software was used to construct a structural equation model to explore the chain mediation role of career development planning and career success in the relationship between nurses' professional values and occupational embeddedness.Results:A total of 763 questionnaires were collected, with 749 valid responses, resulting in an effective recovery rate of 98.17%. The average scores for the 749 nurses were as follows: OESN (60.29±7.65), NPVS-R (108.99±11.82), NCPQ (42.98±4.44), CSSN (73.57±8.34). All four scale scores were positively correlated with each other ( P<0.05). The chain mediation effect of career development planning and career success in the relationship between nurses' professional values and occupational embeddedness was established, with the total indirect effect accounting for 46.04% (0.302/0.656) of the total effect and the chain mediation effect of career development planning and career success accounting for 10.21% (0.067/0.656) . Conclusions:The level of occupational embeddedness among nurses needs further improvement. Nurses' professional values not only directly influence their level of occupational embeddedness but also affect their career development planning, which in turn impacts their career success, ultimately exerting an indirect effect on occupational embeddedness. Nursing managers should strengthen nurses' professional values, assist them in formulating clear career development plans, and provide timely feedback and recognition of career success.

Objective:To investigate the clinicopathological features, molecular pathology characteristics, and prognosis of non-small cell lung carcinoma (NSCLC) exhibiting co-expression of p40 and thyroid transcription factor1 (TTF1).Methods:Clinical and pathological data of six NSCLC cases with co-expression of p40 and TTF1 diagnosed at the First People′s Hospital of Xiaoshan District, Hangzhou, China from January 2016 to December 2023 were collected. Relevant literature was also reviewed.Results:NSCLC with co-expression of p40 and TTF1 commonly occurred in male smokers and had been in stage Ⅲ-Ⅳ when diagnosis. Microscopic examination revealed that the tumor cells were arranged in solid nests and sheets with marked atypia and visible mitotic figures. There was no prominent evidence of keratinization or glandular formation. The tumor cells diffusely co-expressed p40 and TTF1, exhibiting a dual immunophenotype characteristic of both squamous cell carcinoma and adenocarcinoma. Molecular testing of four NSCLC co-expressing p40 and TTF1 revealed the presence of common EGFR mutations, as well as mutations of NRAS (mutation rate of 2.09%), EML4-ALK (mutation rate of 24.77%), and PIK3CA (exon 10 c.1658 G>C p.S553T, mutation rate of 4.32%). All six tumors were poorly differentiated, highly invasive, and associated with poor prognosis. Four of the six patients experienced widespread metastasis and died within 7 to 30 months after the diagnosis or initial treatment.Conclusions:NSCLC with co-expression of p40 and TTF1 exhibits distinct clinicopathological features, immunophenotypes, molecular alterations, and clinical outcomes, characterized by rapid progression and poor prognosis. Pathologists should be vigilant in recognizing this entity to avoid misdiagnosis and missed diagnosis.

Objective To investigate the mechanism by which Erastin affects ferroptosis in lung fibroblasts.Meth-ods Mouse lung fibroblasts (C57/B6-L) were treated with varying concentrations of the iron death inducer Eras-tin.Cell viability was assessed using the cell counting Kit-8 (CCK-8) assay.Oxidative stress levels were visualized using a fluorescence microscope, and the expression of proteins related to the mitogen-activated protein kinase (MAPK) signaling pathway was analyzed using Western blot.Additionally, the p38 and extracellular regulated protein kinase (ERK) inhibitors SB203580 and U0126 were employed to further elucidate the mechanism by which Erastin induces iron death in lung fibroblasts.Results At a concentration of 100 μmol/L, Erastin effectively in-duced ferroptosis in lung fibroblasts, leading to an upregulation of oxidative stress.Furthermore, the phosphoryla-tion levels of p38 and ERK proteins in the MAPK pathway were elevated (P<0.05) .The addition of SB203580 and U0126 inhibitors resulted in a significant reduction in oxidative stress levels and a notable increased in cell ac-tivity in lung fibroblasts (P<0.05).Conclusion It can be concluded that Erastin induces ferroptosis in lung fi-broblasts, potentially through the mediation of oxidative stress via the MAPK signaling pathway.

Objective To evaluate the effectiveness of filter membranes made from different materials in monitoring the health status of rodents in barrier environment facilities by investigating their microbial capture performance.Methods Pasteurella pneumotropica(Pp)and Staphylococcus aureus(Sa)were used as representative strains to simulate the process of microbial capture by filter membranes under laboratory conditions.The microbial capture effectiveness of five self-selected filter membranes(M1,M2,M3,M4,and M5)with adsorption and breathability properties and a commercial filter membrane(T1)were comprehensively evaluated based on captured dust mass,minimum detection limit,and differences in Ct values obtained through fluorescence quantitative PCR detection.The best-performing self-selected filter membrane was placed in the ventilation ducts of cage racks within the barrier facility,with sentinel mice in corresponding cage racks as the control group.Staphylococcus epidermidis and Escherichia coli were used as indicator bacteria to calculate the positive detection rate and coincidence rate,thereby exploring the feasibility of using microbial capture filter membranes to monitor the health status of experimental animals in barrier facilities.Results In terms of the captured dust mass,the self-selected filter membrane M3(non-woven filter membrane with a diameter of 0.1 μm);showed a capture effectiveness second only to T1,with a capture mass of 0.126 g.For Sa,all filter membranes except M4 had a minimum detection limit of 102 CFU/g.For Pp,the minimum detection limit for all filter membranes was 102 CFU/g.However,the Ct value of the quantitative fluorescence PCR amplification results for M3 was significantly lower than that of other materials,indicating that M3 had the best capture performance among the five self-selected materials.In the filter detection verification experiment,the positive detection rate of Staphylococcus epidermidis in sentinel mouse feces and M3 was 50.00％(6/12)and 58.33％(7/12),respectively,with a coincidence rate of 92％.The positive detection rate of Escherichia coli in both sentinel mouse feces and M3 was 50.00％(6/12),with a coincidence rate of 100％.Conclusion Among the 5 self-selected filter membranes,M3 exhibits the best capturing performance.Within the barrier environment facilities,M3 outperforms sentinel mice in monitoring Staphylococcus epidermidis.Therefore,non-woven filter membrane with a diameter of 0.1 μm;can be used as the material for microbial capture filter membranes,providing valuable insights for the selection and application of microbial capture filter membranes used in PCR monitoring of cage exhaust air dust.

Affective brain-computer interfaces (aBCIs) has important application value in the field of human-computer interaction. Electroencephalogram (EEG) has been widely concerned in the field of emotion recognition due to its advantages in time resolution, reliability and accuracy. However, the non-stationary characteristics and individual differences of EEG limit the generalization of emotion recognition model in different time and different subjects. In this paper, in order to realize the recognition of emotional states across different subjects and sessions, we proposed a new domain adaptation method, the maximum classifier difference for domain adversarial neural networks (MCD_DA). By establishing a neural network emotion recognition model, the shallow feature extractor was used to resist the domain classifier and the emotion classifier, respectively, so that the feature extractor could produce domain invariant expression, and train the decision boundary of classifier learning task specificity while realizing approximate joint distribution adaptation. The experimental results showed that the average classification accuracy of this method was 88.33% compared with 58.23% of the traditional general classifier. It improves the generalization ability of emotion brain-computer interface in practical application, and provides a new method for aBCIs to be used in practice.
