Background and Aims:Acute pancreatitis(AP)accompanied by intestinal injury and intestinal barrier dysfunction can significantly worsen AP prognosis.Currently,there is no effective clinical treatment for AP-related intestinal dysfunction.Ulinastatin(UTI)is a conventional drug used for AP treatment due to its ability to inhibit trypsin activity and exert anti-inflammatory effects.However,whether UTI directly improves AP-related intestinal injury remains unclear.Therefore,this study was conducted to investigate the therapeutic effects and potential mechanisms of UTI in AP-related intestinal dysfunction.Methods:Thirty rats were equally randomized into three groups and received intraperitoneal injections of PBS(control group),20%L-arginine(AP group),or 20%L-arginine+UTI(UTI group).Tail vein blood samples were collected at 0,24,and 48 h after the initial injection of L-arginine(or PBS),and the rats were euthanized after the final blood collection to obtain pancreatic and terminal ileum tissues.Serum levels of amylase,lipase,intestinal fatty acid-binding protein(I-FABP),and diamine oxidase(DAO)were measured using ELISA.Histopathological examinations of the pancreas and terminal ileum were conducted.Western blot was used to detect the protein expression levels of tumor necrosis factor α(TNF-α),interleukin 6(IL-6),interleukin 1β(IL-1β),and interleukin 10(IL-10)in terminal ileum tissue.Western blot and qRT-PCR were used to assess the protein and mRNA expression levels of Toll-like receptor 4(TLR4)and nuclear factor κB(NF-κB)p-p65 in the terminal ileum.Results:Compared with the control group,both the AP and UTI groups exhibited significant AP changes(elevated serum amylase and lipase levels,pancreatic histopathological damage)and AP-related intestinal injury(decreased I-FABP and DAO levels,ileal histopathological damage).However,these alterations were significantly less severe in the UTI group compared to the AP group(all P<0.01).Compared with the control group,both the AP and UTI groups showed significantly increased protein expression of pro-inflammatory factors(TNF-α,IL-1β,IL-6)and the anti-inflammatory factor IL-10 in the ileal tissue;however,the UTI group exhibited significantly lower levels of pro-inflammatory factors and higher levels of IL-10 compared to the AP group(all P<0.01).Additionally,compared with the control group,both the AP and UTI groups displayed significant upregulation of TLR4 and NF-κB p-p65 protein and mRNA expressions in ileal tissue,but the upregulations were significantly lower in the UTI group compared to the AP group(all P<0.01).Conclusion:UTI can inhibit the activation of the TLR4/NF-κB signaling pathway in the ileal tissue of AP rats,thereby reducing pro-inflammatory cytokine levels and increasing anti-inflammatory cytokine levels.Therefore,in addition to its anti-pancreatitis effects,UTI may have a direct therapeutic effect on AP-related intestinal dysfunction.

Background and Aims:Coactivator-associated arginine methyltransferase 1(CARM1)is involved in the regulation of RNA and protein processing.Recent studies have revealed its crucial role in tumorigenesis and cancer progression.However,the correlation between CARM1 expression,pan-cancer prognosis,and the immune microenvironment remains unclear.This study was conducted to investigate the relationship between CARM1 expression and pan-cancer prognosis,immune microenvironment,and its potential biological mechanisms using bioinformatics approaches.Methods:Using the TCGA,GTEx,and HPA databases,the expression pattern of CARM1 in various cancers and its prognostic relevance were analyzed.The correlation between CARM1 expression and the tumor microenvironment,as well as immune checkpoint genes,were analyzed using TCGA data.The PPI network of CARM1-interacting genes was constructed using the STRING database.GSEA was performed to investigate the potential biological mechanisms of CARM1 in pan-cancer.Results:Compared to normal tissues,CARM1 was upregulated in most tumor tissues,and its expression was associated with prognosis in multiple cancers.CARM1 expression was correlated with immune cell infiltration and immune checkpoint gene expression.Enrichment analysis suggested that CARM1 might alter the biological function of urinary system tumors by affecting ribosome biogenesis.Additionally,it may influence the biological functions of digestive system tumors by modulating arginine biosynthesis,DNA replication,and the cell cycle.Conclusion:CARM1 is aberrantly expressed in tumor tissues and may serve as a prognostic biomarker for multiple cancers.It is associated with the tumor microenvironment and immune checkpoint gene expression in pan-cancer and may contribute to tumorigenesis through multiple biological pathways,making it a potential therapeutic target for pan-cancer treatment.

Acute pancreatitis(AP)is a severe digestive system emergency characterized by high morbidity and mortality,with a complex pathogenesis involving multiple signaling pathways.Among them,the RhoA/ROCK signaling pathway plays a crucial role in the onset and progression of AP,influencing pancreatic inflammation,fibrosis,microcirculatory regulation,and interactions with other signaling pathways.Studies have shown that inhibiting the RhoA/ROCK signaling pathway can effectively alleviate AP severity,reduce inflammatory cytokine levels,and improve pancreatic microcirculation,offering new therapeutic insights and potential strategies for AP treatment.Therefore,this review systematically summarizes the structure and function of the RhoA/ROCK signaling pathway,explores its mechanistic role in AP progression,and further discusses its potential clinical applications.By integrating existing research findings,this paper aims to provide new perspectives on the role of this signaling pathway in AP and offer a theoretical foundation for future basic research and clinical applications.

Pancreatic cancer is a highly aggressive malignancy with a poor prognosis,and surgical resection remains the only potentially curative treatment.However,since most patients are diagnosed at a locally advanced or metastatic stage,the feasibility of upfront surgery is limited.In recent years,neoadjuvant and conversion therapy have emerged as crucial strategies for borderline resectable and locally advanced pancreatic cancer,aiming to increase the R0 resection rate and improve survival outcomes.Studies have shown that FOLFIRINOX and gemcitabine plus nab-paclitaxel are commonly used neoadjuvant chemotherapy regimens,with the former being more suitable for patients with good performance status,while the latter is better tolerated across a broader patient population due to its lower toxicity.Additionally,radiotherapy,such as stereotactic body radiotherapy(SBRT),can enhance local tumor control,increase tumor cell eradication,and minimize damage to normal tissues,thereby optimizing overall treatment efficacy.Despite the significant advantages of this approach,challenges remain,including the management of toxic side effects and the optimization of treatment protocols.Future research will focus on personalized precision medicine,integrating genomic sequencing and radiomics to refine neoadjuvant/conversion therapy strategies and exploring the combination of chemotherapy,radiotherapy,immunotherapy,and targeted therapy to improve long-term survival in pancreatic cancer patients.This paper summarizes recent advancements in neoadjuvant/conversion therapy combined with radiotherapy for pancreatic cancer and discusses its potential role in modulating tumor biology and optimizing treatment strategies.

Metabolic-bariatric surgery(MBS)has become an important treatment for pathological obesity and metabolic diseases.However,common postoperative nutritional complications—such as protein-energy malnutrition,iron deficiency anemia,and vitamin B12 deficiency—significantly affect patients' long-term prognosis.Traditional nutritional management models rely on static monitoring and standardized supplementation,which are insufficient to address individual variability and dynamic postoperative changes.Artificial intelligence(AI),through integrating multimodal data(such as biochemical indicators,imaging information,and wearable device monitoring)and intelligent modeling,offers new approaches for dynamic monitoring,risk prediction,and personalized intervention.Based on literature from 2017 to 2025,this article systematically evaluates the application of AI in perioperative nutritional management for MBS,covering key technologies including machine learning,deep learning,and natural language processing.It also analyzes current challenges in clinical translation,such as data fragmentation,lack of model interpretability,and limited long-term validation.In the future,enhanced multi-center collaboration,the development of standardized databases,and explainable models will be essential to advancing nutritional management in MBS from empirical practice to precision medicine.

With the rising incidence of hiatal hernia and gastroesophageal reflux disease,surgical techniques urgently require refinement to improve patient outcomes.Guided by the concept of"anatomical priority",Professor Chen Shuang's team has established a standardized seven-step laparoscopic protocol,emphasizing three key components:precise dissection of the"sacred plane",three-dimensional crural reconstruction,and tension-controlled fundoplication.To address limitations such as restricted intraoperative visualization and poor reproducibility,the team further developed the innovative"necktie traction technique".This method employs a red pediatric catheter to create a dynamic traction system,enabling directional field exposure,axial esophageal repositioning,and quantitative control of fundoplication.Integrating biomechanical principles,the technique provides a visualized and standardized operative pathway,significantly enhancing surgical safety,efficacy,and reproducibility.As a novel approach combining anatomical restoration with functional anti-reflux reconstruction,the"necktie technique"offers robust technical support for the standardized promotion of laparoscopic anti-reflux surgery.

Retroperitoneal sarcoma is a rare but highly malignant type of soft tissue tumor,and its diagnosis and treatment have long been focal points in clinical research.In December 2021,the Japanese Society for Sarcoma Research,together with several other medical organizations,published the Clinical practice guidelines for the management of retroperitoneal sarcoma,which were revised in April 2023.The guidelines provide recommendations on three key aspects:the diagnosis of retroperitoneal tumors,treatment of primary retroperitoneal sarcomas,and management of recurrent or unresectable cases.They also address 11 clinical questions derived from these topics and,for the first time,present a systematic diagnostic and treatment algorithm for this disease—offering important reference value for standardizing the management of retroperitoneal sarcoma in China.The diagnostic process includes assessment of clinical features,imaging evaluation,pathological diagnosis,and biopsy.Despite the technical challenges,surgical resection remains the mainstay of treatment,with a particular emphasis on achieving R0 resection.In addition,chemotherapy,radiotherapy,particle therapy,and targeted therapy also play crucial roles.This article focuses on analyzing and discussing the guideline's recommendations on imaging,pathological diagnosis,and surgical resection,in comparison with other domestic and international guidelines.It further explores the effectiveness of current non-surgical treatment strategies based on recent advances in particle and immunotherapy,and looks ahead to the prospects of improving patient outcomes through personalized treatment,multimodal therapy,and multidisciplinary collaboration.

Background and Aims:Polycystic ovary syndrome(PCOS)is a common endocrine disorder among obese women,often accompanied by psychological issues such as anxiety and depression.Laparoscopic sleeve gastrectomy(LSG)is an effective treatment for obesity and its related metabolic conditions,and has shown clear benefits in improving weight and metabolic profiles in PCOS patients.However,the potential mechanisms by which psychological status may affect weight loss outcomes remain unclear.This study aimed to evaluate the psychological characteristics of obese patients with PCOS and explore their impact on postoperative weight loss outcomes,in order to provide evidence for individualized intervention strategies.Methods:Female obese patients scheduled for LSG between November 2020 and September 2022 were enrolled and divided into PCOS and non-PCOS groups.Standardized psychological scales were used to assess anxiety,depression,self-esteem,and eating behaviors.Weight loss outcomes were recorded at 6 and 12 months postoperatively.Propensity score matching was used to control for confounding factors such as age and body mass index(BMI),and correlation analysis was conducted to explore the relationship between psychological status and weight loss outcomes.Results:A total of 314 patients were included,with 130 cases(41.4％)in the PCOS group.Before matching,the PCOS group had significantly worse psychological indicators and lower weight loss outcomes compared to the non-PCOS group(all P＜0.05);after matching,these differences were no longer statistically significant(all P＞0.05).Emotional eating was positively correlated with 12-month weight loss outcomes in the PCOS group,while anxiety and internalized weight stigma were associated with weight loss outcomes in the non-PCOS group(P＜0.05).Additionally,among patients with moderate and extreme obesity,weight loss outcomes in the PCOS group were superior to those in the non-PCOS group(P＜0.05).BMI was negatively correlated with self-esteem,eating behaviors,and quality of life(all P＜0.05).Conclusion:Obese patients with PCOS exhibit notable psychological distress.However,after controlling for BMI and age,their psychological status and weight loss outcomes are comparable to those of non-PCOS patients.BMI may serve as an important confounding factor,and psychological factors may influence weight loss indirectly through eating behaviors.Preoperative psychological screening and intervention are recommended.
