Gastric ulcer （GU） is a high-incidence digestive system disease characterized pathologically by disruption of gastric mucosal integrity， with clinical features including a prolonged course and periodic recurrence. Modern medicine attributes its pathogenesis to the dynamic imbalance between aggressive and defensive factors，while traditional Chinese medicine （TCM） posits its development as closely linked to spleen deficiency. Current therapies combining acid suppressants and antibiotics face challenges such as high recurrence rates，poor mucosal healing，and adverse drug reactions. Long-term use may induce metabolic disturbances like hypergastrinemia and reduced intestinal microbiota diversity. Therefore，exploring safer and longer-lasting therapeutic strategies has become a critical focus. TCM has extensive clinical experience and unique advantages in GU prevention and treatment. Studies demonstrate that the classic formula Shenling Baizhu San exhibits therapeutic properties of "invigorating spleen and tonifying Qi to restore physiological balance and eliminating dampness and regulating middle energizer to unblock Qi movement"， enabling a holistic approach targeting both symptoms and root causes in GU with spleen deficiency as the core pathology by suppressing aggressive factors and strengthening defensive factors. Experimental research reveals its mechanisms involve enhancing the physicochemical barrier of the mucus layer，repairing epithelial barriers and microcirculation，modulating gastric acid secretion and gastrointestinal motility，and regulating microecological barriers and mucosal immunity. Clinical evidence confirms its synergistic effects in promoting ulcer healing，improving Helicobacter pylori eradication rates，and reducing recurrence risks. This review examined the etiology and pathogenesis of GU and systematically evaluated Shenling Baizhu San from three perspectives-clinical application，pharmacological effects， and experimental research-to provide insights for optimizing integrated traditional Chinese and Western medicine protocols and expanding its clinical applications.

Soybean meal (SBM) prepared by soybean crushing is the most popular protein source in the poultry and livestock industries (Cai et al., 2015) due to its economic manufacture, high protein content, and good nutritional value. Despite these benefits, SBM contains various antigen proteins such as glycinin and β-conglycinin, which account for approximately 70% of the total proteins of the SBM and reduce digestibility and damage intestinal function (Peng et al., 2018). Treating SBM with proteases (neutrase, alcalase, and trypsin) or fermentation can eliminate these antigen proteins (Contesini et al., 2018). Because of its safety and rapid growth cycle, Bacillus strains are considered ideal for the fermentation industry (Yao et al., 2021). SBM fermented by Bacillus yields products with high nutritional value and low levels of antinutritional factors (ANFs), stimulating research in this area (Yuan et al., 2017). Kumari et al. (2023) demonstrated that fermentation with Bacillus species effectively degrades antigen proteins and increases crude protein content. The degradation of antigen proteins relies on protease hydrolysis. Low protease production is the major obstacle hindering the widespread use of microbial fermentation techniques.

Probiotics are natural systems bridging synthetic biology, physical biotechnology, and immunology, initiating innate and adaptive anti-tumor immune activity. We previously constructed an all-in-one engineered food-grade probiotic Lactococcus lactis (FOLactis) which could boost the crosstalk among different immune cells such as dendritic cells (DCs), natural killer cells, and T cells. Herein, considering the limited clinical efficacy of naked personalized neoantigen peptide vaccines, we decorate FOLactis with tumor antigens by employing a Plug-and-Display system comprising membrane-inserted peptides. Intranodal injection of FOLactis coated with neoantigen peptides (Ag-FOLactis) induces robust DCs presentation and neoantigen-specific cellular immunity. Notably, Ag-FOLactis not only triggers a 45-fold rise in the quantity of locally reactive neoantigen-specific T cells but also induces epitope spreading in both subcutaneous and metastatic tumor-bearing models, leading to potent inhibition of tumor growth. These findings imply that Ag-FOLactis represents a powerful platform to rapidly and easily display antigens, facilitating the development of a bio-activated platform for personalized therapy.

Soil cadmium (Cd) pollution is one of the major environmental problems globally. Ophiopogon japonicus, a multifunctional plant extensively used in traditional Chinese medicine, has demonstrated potential in environmental remediation. This study investigated the Cd accumulation pattern of O. japonicus under cadmium stress and identified the heavy metal ATPase (HMA) family members in this plant. Our results demonstrated that O. japonicus exhibited a Cd enrichment factor (EF) of 2.75, demonstrating strong potential for soil Cd pollution remediation. Nine heavy metal ATPase (HMA) members of P1B-ATPases were successfully identified from the transcriptome data of O. japonicus, with OjHMA1-OjHMA6 classified as the Zn/Co/Cd/Pb-ATPases and OjHMA7-OjHMA9 as the Cu/Ag-ATPases. The expression levels of OjHMA1, OjHMA2, OjHMA3, and OjHMA7 were significantly up-regulated under Cd stress, highlighting their crucial roles in cadmium ion absorption and transport. The topological analysis revealed that these proteins possessed characteristic transmembrane (TM) segments of the family, along with functional A, P, and N domains involved in regulating ion absorption and release. Metal ion-binding sites (M4, M5, and M6) existed on the TM segments. Based on the number of transmembrane domains and the residues at metal ion-binding sites, the plant HMA family members were categorized into three subgroups: P1B-1 ATPases, P1B-2 ATPases, and P1B-4 ATPases. Specifically, the P1B-1 ATPase subgroup included the motifs TM4(CPC), TM5(YN[X]₄P), and TM6(M[XX]SS); the P1B-2 ATPase subgroup featured the motifs TM4(CPC), TM5(K), and TM6(DKTGT); the P1B-4 ATPase subgroup contained the motifs TM4(SPC) and TM6(HE[X]GT), all of which were critical for protein functions. Molecular docking results revealed the importance of conserved sequences such as CPC/SPC, DKTGT, and HE[X]GT in metal ion coordination and stabilization. These findings provide potential molecular targets for enhancing Cd uptake and tolerance of O. japonicus by genetic engineering and lay a theoretical foundation for developing new cultivars with high Cd accumulation capacity.

Objective:To explore the barriers to nurses applying the best evidence for non-pharmacologic prophylactic management of venous thromboembolism (VTE) in patients with multiple myeloma (MM), and to provide a basis for the development of clinical responses.Methods:A parallel mixed-methods study was conducted in January 2024 to facilitate the selection of nurses from the hematology department of Affiliated Hospital of Jiangsu University to conduct semi-structured in-depth interviews. Concurrently, convenience sampling was employed to select nursing staff from the same departineat for a quantitative questionnaire survey. The interview outlines based on the theoretical domains framework and the questionnaires based on the Barriers to the Application of the Evidence and Facilitators Scale. The questionnaire was developed based on the Barriers and Facilitators to Evidence Application Scale and combined with qualitative and quantitative analyses to derive barriers to nurses' implementation of best evidence.Results:The qualitative study conducted interviews with 9 female nurses in the hematology department, aged 25-49. The quantitative study surveyed 17 female nurses in the hematology department with an average age of (33.18 ± 9.09) years. Nurses scored high overall in evidence application (156.65 ± 20.09) points, with high scores on the organizational form dimension (34.47 ± 1.48) points, the evidence application leader dimension (44.24 ± 1.30) points, the nurses' team dimension (42.53 ± 1.41) points, and the implementation scenario dimension (11.18 ± 0.61) points, which suggests that nurses were process was well supported overall. Low scores on the evidence dimension (11.94 ± 0.91) points and patient dimension (12.41 ± 1.03) points indicated that nurses had barriers in knowledge acquisition and practical application. The results of qualitative interviews further revealed that nurses encourter multiple challenges when applying best evidence, including insufficient knowledge base, low professional identity within societym, absence of standardized departmental protocols, negative outcome expectations, and inadequate motivation coupled with ulcear objectives.Conclusions:There are multiple clinical factors affecting nurses' application of best evidence, and departments should propose targeted coping strategies based on the barrier factors to ensure the successful implementation of evidence-based practice changes, and thus advance the clinical application of best evidence for non-pharmacological prevention of VTE in MM patients.

Pediatric severe pneumonia is characterized by an abrupt onset and swift progression，frequently complicated by serious complications，which is the leading cause of death in children under 5 years old. In recent years，the prevalence of gram-negative bacterial infections in severe pneumonia patients has been on the rise，and the inappropriate use of antibiotics has augmented the resistance of bacteria，thereby complicating their treatment. Therefore，early diagnosis and timely treatment are particularly critical. This review provided the common gram-negative bacteria，risk factors and triggers，microbiological testing methods，resistance mechanism，and treatment in children with severe pneumonia，with the aim of providing clinically useful guidance for pediatricians when treating such patients.

[Objective]To explore the therapeutic effect of wrist-ankle acupuncture in postoperative analgesia of mixed hemorrhoids.[Methods]Eighty patients with mixed hemorrhoid after surgery under lumbar anesthesia were randomly divided into experimental group and control group,with 40 cases in each group.The control group received routine postoperative treatment and nonsteroidal anti-inflammatory drugs(NSAIDs),100 mg Tramadol was intramuscularly injected when the visual analogue score(VAS)≥7.The experimental group received wrist-ankle acupuncture treatment firstly when the VAS≥7,if the VAS was still≥7 after half an hour,the 100 mg Tramadol was intramuscularly injected.Compare the VAS scores of two groups before the first intervention and 0.5 hour after the intervention,as well as at 6,12,18,24,36 and 48 hours after surgery.Compare the frequency of Tramadol use at 48 hours after surgery and the changes in prostaglandin E2(PGE2)and 5-hydroxytryptamine(5-HT)levels before and 0.5 hour after the first intervention.[Results]There was no significant statistical difference in VAS scores between experimental group and control group before the first intervention(P＞0.05).The VAS scores of both groups 0.5 hour after the first intervention were lower than before the intervention in the same group(P＜0.05).The VAS score of experimental group patients after the first intervention for 0.5 hour was higher than that of control group(P＜0.05).The VAS scores of experimental group at 6,12,18,24,36 and 48h after surgery were lower than those of control group at the same time point(P＜0.05).The frequency of using Tramadol in experimental group was lower than that in control group 48 hours after surgery(P＜0.05).There was no significant statistical difference in PGE2 and 5-HT levels between experimental group and control group before intervention(P＞0.05).The PGE2 and 5-HT levels in experimental group and control group decreased after intervention for 0.5 hour compared to before intervention in the same group(P＜0.05).The PGE2 and 5-HT levels in experimental group were higher than those in control group after 0.5 hour of intervention(P＜0.05).[Conclusion]Wrist-ankle acupuncture therapy can effectively alleviate postoperative pain in patients with mixed hemorrhoids,reduce the use of postoperative analgesics,and its analgesic mechanism may be related to downregulating the serum levels of PGE2 and 5-HT,which has certain clinical application value..

Objective To explore correlations of expression levels of microRNA-147(miR-147),Ki-67 and carcinoembryonic antigen(CEA)with lymph node metastasis of invasive lung adenocarci-noma.Methods A total of 160 patients with invasive pulmonary adenocarcinoma were selected as study subjects.Based on presence of lymph node metastasis,patients were divided into lymph node metastasis group(n=74)and non-lymph node metastasis group(n=86).Immunohistochemistry was employed to detect the expression levels of miR-147 and Ki-67 in cancer tissues.The serum CEA level was measured using the chemiluminescence method.The correlations of the expression levels of miR-147,Ki-67 and serum CEA with the clinicopathological characteristics of patients were analyzed.The value of miR-147,Ki-67 and CEA in predicting lymph node metastasis was evaluated using the receiver operating characteristic(ROC)curve.Results The expression level of miR-147 in the lymph node metastasis group was significantly lower than that in the non-lymph node metastasis group,while the expression levels of Ki-67 and serum CEA were significantly higher in the lymph node me-tastasis group than in the non-lymph node metastasis group(P＜0.05).Patients with a tumor diameter≥3 cm or TNM stage Ⅲ to Ⅳ had significantly lower miR-147 expression levels in cancer tissues compared to those with a tumor diameter＜3 cm or TNM stage Ⅰ to Ⅱ(P＜0.05).The Ki-67 ex-pression level in cancer tissues was significantly higher in patients with a tumor diameter ≥3 cm than in those with a tumor diameter＜3 cm(P＜0.05).The serum CEA level was significantly higher in patients with TNM stage Ⅲ to Ⅳ than in those with TNM stage Ⅰ to Ⅱ(P＜0.05).The expres-sion level of miR-147 was negatively correlated with Ki-67,serum CEA and lymph node metastasis(P＜0.05);Ki-67 and serum CEA were positively correlated with lymph node metastasis(P＜0.05);Ki-67 was positively correlated with serum CEA(P＜0.05).The areas under the ROC curves for miR-147,Ki-67 and CEA in predicting lymph node metastasis were 0.785,0.835 and 0.798,respectively(P＜0.05).Conclusion The expression levels of miR-147 and Ki-67 in cancer tissues and the serum CEA level are correlated with lymph node metastasis in invasive pulmo-nary adenocarcinoma.

Objective:This study aimed to retrospectively analyze the incidence and influencing factors of tricuspid regurgitation (TR) in the short term after pacemaker lead implantation at the Second Affiliated Hospital of Zhejiang University School of Medicine, so as to provide evidence for understanding pacemaker lead-related TR.Methods:Consecutive patients who underwent single- or dual-chamber permanent pacemaker implantation between June 2019 and December 2023 in the Department of Cardiology were enrolled. General clinical data and relevant parameters were collected. Changes in TR severity before and shortly after the procedure were assessed using echocardiography. TR progression was defined as an increase by one grade or more, and TR improvement as a decrease by one grade or more. Logistic regression analysis was employed to identify factors associated with TR progression.Results:A total of 219 patients were included (128 males, 91 females), with a mean age of 69.7 ± 11.2 years. The median follow-up time was 99 (26, 199) days. TR remained unchanged in 114 patients (52.1%), improved in 46 (21.0%)—including 36 (16.4%) with one-grade reduction, 9 (4.1%) with two-grade reduction, and 1 (0.5%) with three-grade reduction—and progressed in 59 patients (26.9%). Among those with progression, 51 (23.3%) had mild-to-moderate TR worsening by one grade, and 8 (3.7%) had moderate or worse TR worsening by at least two grades. Notably, one case involved lead perforation of the leaflet and two cases had lead impingement. Compared with the non-progression group ( n = 114), pacemaker indication (AV block vs. sick sinus syndrome), baseline left atrial diameter, pulmonary artery systolic pressure (PASP), and the severity of mitral regurgitation (MR) and TR were significantly associated with TR progression or improvement (all P < 0.05). Ordinal logistic regression analysis identified preoperative TR severity [ OR=10.57 (3.77–29.68), P < 0.001] and pacemaker indication [ OR=0.452 (0.222–0.918), P = 0.028] as independent predictors of postoperative TR progression. Patients with AV block were more likely to receive left bundle branch pacing ( P < 0.001), which may contribute to their lower risk of TR. Conclusions:Short-term progression of TR after pacemaker implantation is relatively common, although severe TR remains rare. Preoperative TR severity and pacemaker indication are independent predictors of short-term TR progression. The use of physiological pacing modalities may help reduce the incidence of TR following pacemaker lead implantation.

Objective:To explore the health education needs of patients undergoing fecal microbiota transplantation (FMT) at different stages of treatment.Methods:A qualitative research method was employed and an interview guide based on timing theory was developed. Semi-structured interviews were conducted with patients treated for colorectal conditions with FMT at Tenth People's Hospital of Tongji University from August to October 2022. Data from the interviews were analyzed using thematic analysis.Results:A total of 19 patients aged 20 to 65 were interviewed, including seven males and 12 females. A total of five main themes and 15 subthemes were identified: health education demands during the diagnosis phase (basic information about FMT; knowledge about donor screening), health education demands during the preparation phase (alleviating discomfort caused by nasoenteric tubes; interpretation of examination reports), health education demands during the execution phase (dietary guidance during FMT; exercise guidance during FMT; medication and supplementary training guidance; management of adverse reactions), health education demands during the adaptation phase (consolidating treatment effects; knowledge related to FMT capsules; post-discharge follow-up content and methods; post-discharge precautions), long-term health education demands (diverse health education tools; individualized health education approaches; alleviating psychological anxiety) .Conclusions:Patients undergoing FMT have numerous concerns, and diverse health education needs throughout the treatment process. Healthcare professionals should adopt various health education strategies to address these needs.
