Objective To explore the effects of behavior change intervention based on the multi-ple-theory model on patients with dyslipidemic ischemic stroke.Methods A total of 93 patients with dyslipidemic ischemic stroke who were hospitalized in the vascular neurology ward of Beijing Tiantan Hospital,Capital Medical University from January to August 2024 were selected as the study subjects using the convenience sampling method.They were randomly divided into control group(n=49)and intervention group(n=44)using the envelope-drawing method.Patients in the control group re-ceived routine stroke health education,while those in the intervention group underwent a 3-month be-havior change program guided by the multiple-theory model.The levels of healthy behaviors,body mass index(BMI),total cholesterol(TC),triglycerides(TG),high-density lipoprotein(HDL-C),and low-density lipoprotein(LDL-C)were compared between the two groups.Results There were no statistically significant differences in general information and disease-related data between the two groups(P＞0.05).At 1-,3-,and 6-month after the intervention,the level of healthy behaviors in the intervention group was higher than that in the control group,with statistically significant differ-ences(P＜0.05).There was a statistically significant difference in BMI between the two groups at 6 months after the intervention(P＜0.05).The TC levels in the intervention group at 3 and 6 months after the intervention were lower than those in the control group,with statistically significant differences(P＜0.05).The HDL-C level in the intervention group at 6 months after the intervention was high-er than that in the control group,with a statistically significant difference(P＜0.05).The LDL-C levels in the intervention group at 1-,3-,and 6-month after the intervention were lower than those in the control group,with statistically significant differences(P＜0.05).There were no statistically significant differences in TG levels between the intervention group and the control group at different time points after the intervention(P＞0.05).Conclusion The behavior change intervention pro-gram based on the multiple-theory model can effectively improve and maintain healthy behaviors and improve blood lipid levels in patients with dyslipidemic ischemic stroke.

Cancer is a serious global health problem and a major cause of human death. Conventional cancer treatments often run the risk of impairing vital organ functions. Anticancer peptides (ACPs) are considered to be one of the most promising therapeutic agents against common human cancers due to their small sizes, high specificity, and low toxicity. Since ACP recognition is highly limited to the laboratory, expensive, and time-consuming, we proposed pLM4ACP, a model for predicting ACPs based on machine learning and protein language models. In this model, the protein language model ProtT5 was used to extract the features of ACPs, and the extracted features were input into the support vector machine (SVM) classification algorithm for optimization and performance evaluation. The model showcased significantly higher accuracy than other methods, with the overall accuracy of 0.763, F1-score of 0.767, Matthews correlation coefficient of 0.527, and area under the curve of 0.827 on the independent test set. This study constructs an efficient anticancer peptide prediction model based on protein language models, further advancing the application of artificial intelligence in the biomedical field and promoting the development of precision medicine and computational biology.

Objective:To visually analyze the research hot-spots and development trends of pelvic floor dysfunction nursing, in order to provide a reference for the research of pelvic floor dysfunction nursing in China.Methods:The China National Knowledge Infrastructure (CNKI) and Web of Science core collection were used as the retrieval databases to retrieve the literature in the field of pelvic floor dysfunction nursing from the establishment of the database to January 31, 2025. CiteSpace 6.4.R1 software was used to visually analyze the included literature.Results:A total of 1 947 Chinese articles and 4 931 English articles were included. The number of English literature increased year by year, while Chinese literature showed a downward trend since 2019. There were more and stable core authors and core institutions in foreign research, while there was less cooperation among domestic authors and institutions. The research hotspots abroad mainly focused on improving the quality of nursing care and managing specific health problems. The future development trends were primarily randomized controlled trials, tension-free vaginal tape, postoperative care, and patient experience. The research hotspots in China mainly focused on nursing interventions. The future development trends were primarily patient quality of life and effectiveness evaluation.Conclusions:Due to different development stages, compared with foreign countries, there are still some deficiencies in evidence-based medicine, delicacy of nursing after tension-free vaginal tape, patient experience, innovation of nursing technology, and depth and breadth of nursing research in China. In the future, we should learn from foreign studies to promote the development of nursing research on pelvic floor dysfunction in China.

Hypercholesterolemia is a significant risk factor for the development of atherosclerosis. 2',3',5'-Tri-O-acetyl-N ⁶-(3-hydroxyphenyl) adenosine (IMM-H007), a novel AMPK agonist, has shown protective effects in metabolic diseases. However, its impact on cholesterol and triglyceride metabolism in hypercholesterolemia remains unclear. In this study, we aimed to elucidate the effects and specific mechanisms by which IMM-H007 regulates cholesterol and triglyceride metabolism. To achieve this goal, we used Apoe ^-/- and Ldlr ^-/- mice to establish a hypercholesterolemia/atherosclerosis model. Additionally, hepatocyte-specific Ampka1/2 knockout mice were subjected to a 5-week high-cholesterol diet to establish hypercholesterolemia, while atherosclerosis was induced via AAV-PCSK9 injection combined with a 16-week high-cholesterol diet. Our results demonstrated that IMM-H007 improved cholesterol and triglyceride metabolism in mice with hypercholesterolemia. Mechanistically, IMM-H007 modulated the AMPKα1/2-LDLR signaling pathway, increasing cholesterol uptake in the liver. Furthermore, IMM-H007 activated the AMPKα1-FXR pathway, promoting the conversion of hepatic cholesterol to bile acids. Additionally, IMM-H007 prevented hepatic steatosis by activating the AMPKα1/2-ATGL pathway. In conclusion, our study suggests that IMM-H007 is a promising therapeutic agent for improving hypercholesterolemia and atherosclerosis through the activation of AMPKα.

Background and Aims:Biliary tract cancers(BTCs)are highly aggressive malignancies with dismal prognosis,for which radical resection remains the only potentially curative treatment.Laparoscopic surgery has demonstrated superiority over open surgery in perioperative safety and recovery,yet it is technically limited in complex operations.Robot-assisted laparoscopy,with its high-definition three-dimensional vision and enhanced instrument dexterity,may overcome these limitations.However,comparative evidence balancing baseline differences between laparoscopic and robot-assisted laparoscopic radical resections for BTCs is still lacking.This study aimed to evaluate and compare their short-term safety using propensity score matching(PSM).Methods:A total of 151 patients with biliary tract cancers who underwent radical resection were retrospectively enrolled from the Chinese Biliary Tract Tumor Collaborative Group database,including 128 in the laparoscopic group and 23 in the robotic-assisted laparoscopic group.To balance baseline differences,an initial 1∶1 PSM was performed,yielding 19 laparoscopic and 19 robotic cases.Subsequently,using the robotic group as the reference,a 1∶2 PSM was conducted,resulting in 36 laparoscopic and 18 robotic cases.Primary outcomes(conversion to open surgery,ICU admission,and postoperative complications)and secondary outcomes(operative time,intraoperative blood loss,transfusion,postoperative hospital stay,reoperation,readmission,and hospitalization costs)were compared between the two groups.Multivariate regression analyses were performed to explore factors associated with conversion to open surgery and postoperative hospital stay.Results:After matching,baseline characteristics were well balanced between groups.For primary outcomes,the conversion rate to open surgery was significantly higher in the laparoscopic group than in the robotic group(41.7％vs.0,P=0.001),while ICU admission,overall postoperative complications,and Clavien-Dindo graded complications showed no significant differences(all P＞0.05).For secondary outcomes,the postoperative hospital stay was significantly more extended in the laparoscopic group compared with the robotic group(18.5 d vs.8.0 d,P=0.005),whereas operative time,intraoperative blood loss,transfusion,reoperation,readmission,and hospitalization costs were comparable(all P＞0.05).Logistic regression for conversion did not identify statistically significant predictors,but moderately differentiated tumors,elevated preoperative CA19-9,and higher harvested lymph node counts showed trends toward increased risk.Multivariate linear regression revealed that robotic-assisted surgery was an independent factor for reduced postoperative hospital stay(P=0.024),while preoperative total bilirubin(P=0.020),longer operative time(P=0.000),postoperative complications(P=0.006),and reoperation(P=0.005)were found to be associated with a prolonged hospital stay.Conclusion:Robot-assisted laparoscopic radical resection for BTCs is not inferior to conventional laparoscopy in short-term safety and may further reduce conversion rates and hospital stay.Its technical advantages may be particularly valuable in anatomically complex or challenging cases.Nonetheless,cost-effectiveness and resource allocation should be considered for wider adoption.

Objective To investigate the weight loss efficacy and mechanisms of oligopeptide-herbal medicine composite,and to provide new approaches for obesity treatment.Methods Twenty-three SPF female SD rats were randomly divided into control group(n=3)and modeling group(n=20).The control group was fed an ordinary diet for 6 consecutive weeks,and the modeling group was fed a high-fat diet for 6 consecutive weeks to establish a simple obesity rat model.After successful modeling,the modeling group was randomly divided into model group(n=10)and treatment group(n=10).The treatment group started anoint-and-massage therapy with oligopeptide-herbal medicine composite(3 g per rat per time,once a day,20 min each time),which was recorded as day 1.The control group and model group were not treated with oligopeptide-herbal medicine composite but received the same massage,and continued to be fed ordinary feed and high-fat feed respectively.Ten rats in the model group and ten in the treatment group were each divided into 3 groups,with 3,3,and 4 rats in each group.On days 3,6,and 9 after treatment,the rats in the three groups were weighed and cardiac blood collection was performed after isoflurane respiratory anesthesia.After euthanasia by cardiac bloodletting,abdominal subcutaneous adipose tissue(aSAT)and perirenal white adipose tissue(pWAT)samples were collected and weighed.Serum triglycerides(TG)and high-density lipoprotein cholesterol(HDL-C)levels were measured.Image J software was used to measure aSAT thickness and the diameter and area of perirenal white adipocytes and abdominal subcutaneous adipocytes.Immunofluorescence technique was used to observe the number of telocytes(TCs),cell junctions and exosomes per unit area of aSAT.Transmission electron microscopy was used to measure the length of telopodes(Tps)of dermal and subcutaneous TCs in abdominal skin,and to observe the distribution of exosome vesicles,rough endoplasmic reticulum,mitochondria,and cell junctions.Results Compared with the control group,the body weight of rats in the modeling group increased significantly(P＜0.05).Compared with the control group,rats in the model group showed a significant increase in serum TG level,a significant decrease in HDL-C level,and a significant increase in pWAT mass(all P＜0.05).Compared with the model group,the treatment group showed a significantly increased rate of body weight reduction,significantly decreased pWAT mass,significantly decreased serum TG level,and significantly increased HDL-C level(all P＜0.05).Compared with the model group,the treatment group showed significant reductions in aSAT thickness,as well as cell diameter and area in both aSAT and pWAT(all P＜0.05).Compared with the model group,the treatment group showed significantly increased number of TCs per unit area of aSAT,number of exosomes from TCs in aSAT,and Tps length(all P＜0.05).The treatment group showed an increasing trend in the numbers of mitochondria,rough endoplasmic reticulum,and cell junctions in TCs.Conclusion Oligopeptide-herbal medicine composite applied via anoint-and-massage therapy effectively improves obesity-related symptoms such as dyslipidemia and fat accumulation in obese rats by regulating TCs and their intercellular communication.

Gastric cancer is a highly lethal malignant tumor, with early diagnosis being difficult and treatment outcomes influenced by multiple factors. In recent years, comprehensive treatment approach, incorporating surgery, chemotherapy, radiotherapy, targeted therapy, and immuno-therapy, has significantly improved efficacy. The advantages of comprehensive treatment are most important in patients with locally advanced and metastatic gastric cancer. For locally advanced cases, surgery serves as the core treatment, with various therapeutic modalities applied during the peri-operative period to enhance surgical outcomes. For metastatic patients, drug therapy is the primary method, supplemented by local treatments to achieve the best benefit. With the understanding of the molecular mechanisms underlying gastric cancer development, the use of molecular biomarkers for prognostic stratification and guidance for targeted therapy or immuno-therapy has become a crucial aspect of comprehensive treatment. Based on the latest research advancements, the authors discuss comprehensive treatment strategies for gastric cancer at different stages, offering insights into impro-ving efficacy and prognosis.
