Objective To discuss the application value of single-port laparoscopy assisted testicular fixation in treating pediatric inguinal cryptorchidism.Methods A total of 128 children with inguinal cryptorchidism admitted to Jinhua Maternal and Child Health Hospital from June 2024 to March 2025 were enrolled in this study.Using a randomized digital table method,the children were divided into observation group(n=64)and control group(n=64).The observation group underwent single-port laparoscopy assisted testicular fixation surgery,while control group received conventional three-port laparoscopy surgery.Intraoperative blood loss,surgical duration,hospitalization time,hospitalization costs,and incision length,differences in inflammatory markers,pain stress indicators,sex hormone levels,and complications were compared between two groups.Results Compared to control group,the surgical duration and postoperative hospitalization time were shorter in observation group,intraoperative blood loss was lower in observation group,incision length was shorter in observation group,hospitalization costs was higher in observation group,and vancouver scar scale scores was lower in observation group(P＜0.05).One day postoperatively,interleukin-6,superimposed C-reactive protein,and prostaglandin E2 were increased compared to pre-treatment levels in both groups.The reduction in observation group was more significant than that in control group(P＜0.05).One day postoperatively,levels of neuropeptide Y,nerve growth factor,and substance P were decreased in both groups.The increase in observation group was more pronounced than that in control group(P＜0.05).Conclusion Single-port laparoscopy is used for pediatric inguinal cryptorchidism with the advantages of minimally invasive,safety and fast recovery.It can effectively reduce postoperative inflammation and pain response,and does not affect sex hormone level and testicular development,with high clinical application value.

Food-derived bioactive peptides (FBPs), particularly those with ten or fewer amino acid residues and a molecular weight below 1300 Da, have gained increasing attention for their safe, diverse structures and specific biological activities. The development of FBP-based functional foods and potential medications depends on understanding their structure‒activity relationships (SARs), stability, and bioavailability properties. In this review, we provide an in-depth overview of the roles of FBPs in treating various diseases, including Alzheimer's disease, hypertension, type 2 diabetes mellitus, liver diseases, and inflammatory bowel diseases, based on the literature from July 2017 to Mar. 2023. Subsequently, attention is directed toward elucidating the associations between the bioactivities and structural characteristics (e.g., molecular weight and the presence of specific amino acids within sequences and compositions) of FBPs. We also discuss in silico approaches for FBP screening and their limitations. Finally, we summarize recent advancements in formulation techniques to improve the bioavailability of FBPs in the food industry, thereby contributing to healthcare applications.

Objective　To analyze the whole genome sequence characteristics of dengue serotype 2 virus (DENV-2) strains isolated from Guangzhou in 2023, providing new foundational data to support local dengue fever prevention and control efforts. Methods　Dengue viruses were isolated from serum samples of dengue fever patients using C6/36 cells. Whole genome sequencing of dengue virus was performed using Nanopore sequencing technology (Nanopore platform). The sequencing data were assembled utilizing IPH-NANO v1.0 software, and homology analysis, phylogenetic analysis, and amino acid site variation analysis of the dengue virus genome sequence were conducted using software such as BioEdit7.0.9.0, MEGA11, and iqTree1.6.12. Results　A total of 13 DENV-2 isolates were obtained from the serum samples of dengue fever patients in Guangzhou in 2023, all of which were derived from locally infected cases. The whole genome sequences obtained by sequencing and splicing ranged from 10 429-10 439 nt in length. The nucleotide (amino acid) homology among the 13 isolates was 99.7%-99.9% (99.6%-9.9%). A genome-wide phylogenetic analysis showed that the genotypes of all 13 Guangzhou isolates were identified as the Cosmopolitan genotype and were grouped in the same evolutionary clade as isolates from Réunion (French overseas territory), Djibouti, Kenya, and other regions. Compared with the reference sequence (NC001474), a total of 26 amino acid site variations were identified in the C/prM/E protein regions of the 13 isolates, including 4 variations in the C protein region, 8 in the prM protein region, and 14 in the E protein region. Conclusion　The DENV-2 strains isolated from Guangzhou in 2023 exhibited high homology, with closely related isolates primarily originating from countries or regions such as Réunion, Djibouti, and Kenya, it highlights the need for further assessment of the risk of dengue fever importation from East Africa, South Asia, and other regions.

With the rapid development of artificial intelligence, computational pathology has been seamlessly integrated into the entire clinical workflow, which encompasses diagnosis, treatment, prognosis, and biomarker discovery. This integration has significantly enhanced clinical accuracy and efficiency while reducing the workload for clinicians. Traditionally, research in this field has depended on the collection and labeling of large datasets for specific tasks, followed by the development of task-specific computational pathology models. However, this approach is labor intensive and does not scale efficiently for open-set identification or rare diseases. Given the diversity of clinical tasks, training individual models from scratch to address the whole spectrum of clinical tasks in the pathology workflow is impractical, which highlights the urgent need to transition from task-specific models to foundation models (FMs). In recent years, pathological FMs have proliferated. These FMs can be classified into three categories, namely, pathology image FMs, pathology image-text FMs, and pathology image-gene FMs, each of which results in distinct functionalities and application scenarios. This review provides an overview of the latest research advancements in pathological FMs, with a particular emphasis on their applications in oncology. The key challenges and opportunities presented by pathological FMs in precision oncology are also explored.

Coronary artery bypass grafting (CABG) is one of the most effective revascularization treatments for coronary heart disease. Secondary prevention strategies, which rely on antiplatelet and lipid-lowering drugs, are crucial after CABG to ensure the durability of revascularization treatment effects and prevent adverse cardiovascular and cerebrovascular events in the medium to long term. Previous research conducted by Professor Zhao Qiang's team from Ruijin Hospital of Shanghai Jiao Tong University, known as the DACAB study, indicated that dual antiplatelet therapy (DAPT, specifically ticagrelor+aspirin) after CABG can enhance venous graft patency. However, it remains uncertain whether DAPT can further improve the medium to long-term clinical outcomes of CABG patients. Recently, the team reported the medium to long-term follow-up results of the DACAB study, termed the DACAB-FE study, finding that DAPT administered after CABG can reduce the incidence of major cardiovascular events over five years and improve patients' medium to long-term clinical outcomes. This article will interpret the methodological highlights and significant clinical implications of the DACAB-FE study.

Background::Gastric cancer (GC), a malignant tumor with poor prognosis, is one of the leading causes of cancer-related deaths worldwide; consequently, identifying novel therapeutic targets is crucial for its corresponding treatment. NUF2, a component of the NDC80 kinetochore complex, promotes cancer progression in multiple malignancies. Therefore, this study aimed to explore the potential of NUF2 as a therapeutic target to inhibit GC progression. Methods::Clinical samples were obtained from patients who underwent radical resection of GC at Lanzhou University Second Hospital from 2016 to 2021. Cell count assays, colony formation assays, and cell-derived xenotransplantation (CDX) models were used to determine the effects of NUF2 on GC progression. Flow cytometry was used to detect the effect of NUF2 or quercetin on cell cycle progression and apoptosis. A live-cell time-lapse imaging assay was performed to determine the effect of NUF2 on the regulation of mitotic progression. Transcriptomics was used to investigate the NUF2-associated molecular mechanisms. Virtual docking and microscale thermophoresis were used to identify NUF2 inhibitors. Finally, CDX, organoid, and patient-derived xenograft (PDX) models were used to examine the efficacy of the NUF2 inhibitor in GC. Results::NUF2 expression was significantly increased in GC and was negatively correlated with prognosis. The deletion of NUF2 suppressed GC progression both in vivo and in vitro. NUF2 significantly regulated the mitogen-activated protein kinase (MAPK) pathway, promoted G2/M phase transition, and inhibited apoptosis in GC cells. Additionally, quercetin was identified as a selective NUF2 inhibitor with low toxicity that significantly suppressed tumor growth in GC cells, organoids, CDX, and PDX models. Conclusions::Collectively, NUF2-mediated G2/M phase transition and apoptosis inhibition promoted GC progression; additionally, NUF2 inhibitors exhibited potent anti-GC activity. This study provides a new strategy for targeting NUF2 to suppress GC progression in clinical settings.
