Background and Aims:Gastroesophageal reflux disease(GERD)is a common complication following sleeve gastrectomy(SG),particularly in patients with concomitant hiatal hernia,where symptoms tend to be more persistent and refractory,significantly impairing postoperative quality of life.This study aimed to evaluate the efficacy of laparoscopic hiatal hernia repair combined with gastroesophageal fixation in SG patients with severe GERD and hiatal hernia,providing clinical reference for revisional surgical strategies.Methods:The clinical data of 9 patients with severe GERD after SG who underwent laparoscopic hiatal hernia repair and gastroesophageal fixation at Huashan Hospital,Fudan University,between January 2023 and June 2024 were retrospectively analyzed.GerdQ scores,proportion of endoscopically confirmed reflux esophagitis,and proton pump inhibitor(PPI)usage were compared before and after surgery.Surgical parameters and follow-up outcomes were also recorded.Results:All patients successfully completed the surgery without major intraoperative complications,and the mean postoperative hospital stay was 5.22 d.After a mean follow-up period of 15.27 months,the GerdQ score significantly decreased from 11.67±2.00 to 7.22±1.48.The proportion of patients with GerdQ score≥8 decreased from 100.00％to 44.44％,and the rate of endoscopically confirmed GERD dropped from 88.89％to 11.11％;PPI use also significantly declined,with all differences reaching statistical significance(all P＜0.05).Conclusion:Laparoscopic hiatal hernia repair combined with gastroesophageal fixation can effectively alleviate reflux symptoms in SG patients with coexisting hiatal hernia,demonstrating favorable short-term efficacy and high safety.This approach may be a preferable surgical option for selected patients.

Gastroesophageal reflux disease (GERD), a common chronic disease of the digestive system, has a severe impact on the quality of life of patients and simultaneously increases the medical burden. The symptoms of GERD are diverse and atypical, and diagnosis requires a comprehensive assessment of symptoms, endoscopic findings, reflux monitoring, and therapeutic responses. Lifestyle interventions and pharmacological treatment remain the preferred basic treatment modalities for GERD, which have a favorable relieving effect on most of the population. Patients who do not respond to conservative treatment can undergo endoscopic anti-reflux surgery and surgical procedures. For patients with concomitant esophageal hiatal hernia, esophageal hiatal hernia repair can be performed simultaneously. With the high prevalence of obesity and the popularization of bariatric surgery, GERD in the obese population and those after bariatric surgery has gradually received more attention. This article summarizes the current status of the diagnosis and treatment of GERD and prospects the new technologies and research directions in the future.

In recent years， hyperuricemia （HUA） has shown a rapidly increasing incidence and tends to occur in increasingly young people， with a wide range of cardiac， renal， joint， and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage， medication restriction， and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid （UA）， and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology， which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine （TCM） can treat HUA via multiple targets and multiple pathways from a holistic view， with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However， its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA， this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora， intestinal metabolites， intestinal UA transporters， and intestinal barriers. Furthermore， we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology， with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.

Objective This study aims to establish a hidden curriculum-based medical humanities teaching pathway within surgical internship education and evaluate its effectiveness in enhancing students' humanistic care competence.Methods A single-group pre-test and post-test design was adopted.A total of 76 interns from a tertiary teaching hospital in 2024 were in-cluded.A five-dimensional hidden curriculum framework—material,spiritual,behavioral,faculty,and institutional—was con-structed.Humanistic competence was assessed before and after the intervention using the Humanistic Professional Awareness Scale for Healthcare Students and Providers(HPAS-HSP).Results Post-intervention scores significantly improved compared to pre-intervention across the total scale in the three dimensions:personal integrity and responsibility,sensitivity to others,and pro-fessional competence(P＜0.05),with the greatest improvement observed in sensitivity to others.Conclusion The structured hidden curriculum is effective in enhancing medical students' humanistic qualities,especially in fostering emotional resonance and professional identity.Future work should focus on verifying behavioral transformation and developing multi-source evaluation sys-tems to improve effectiveness and applicability.

Objective:To investigate the effects of thioredoxin reductase 1 (TXNRD1) on ferroptosis and immune function of dendritic cells (DCs) in septic mice, and to provide a basis for improving the immunosuppression in sepsis caused by wound infection.Methods:This study was an experimental research. Sixty male C57BL/6J mice aged 6-8 weeks were subjected to cecal ligation and puncture (CLP) to establish sepsis models. Ten mice were selected at 0 (immediately), 6, 12, 24, 48, and 72 h after CLP surgery, respectively, according to the random number table method. Mouse splenic DCs were isolated using CD11c-positive magnetic beads. The protein expressions of TXNRD1, and anti-ferroptosis proteins solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) in the cells were detected by Western blotting, the reduced glutathione (GSH) content in the cells was measured by colorimetric assay, the lipid peroxidation level was assessed via live-cell imaging technology, and the levels of major histocompatibility complex class Ⅱ subtype I-A/I-E and leukocyte differentiation antigens CD80 and CD86 were detected by flow cytometry. Another 100 male C57BL/6J mice aged 6-8 weeks were divided into corn oil+sham injury group, corn oil+CLP group, inhibitor+sham injury group, and inhibitor+CLP group according to the random number table method, with 25 mice in each group. Mice in the two inhibitor groups were intraperitoneally injected with TXNRD1 inhibitor auranofin, while mice in the two corn oil groups were intraperitoneally injected with corn oil. One hour later, mice in the two CLP groups underwent CLP surgery to establish sepsis models, while mice in the two sham injury groups underwent sham surgery. Twenty mice from each group were selected to observe survival within 7 d post-surgery, and the survival rate was calculated. At 24 h post-surgery, mouse splenic DCs from the remaining 5 mice in each group were collected for corresponding assays as above.Results:Compared with those at 0 h after CLP surgery, the protein expressions of TXNRD1, GPX4, and SLC7A11 in mouse cells at 24 h after CLP surgery and the protein expression of TXNRD1 in mouse cells at 48 h after CLP surgery were significantly decreased ( P<0.05), the GSH content in mouse cells was significantly decreased at 24 and 48 h after CLP surgery ( P<0.05). The lipid peroxidation level in mouse cells was low at 0, 6, and 12 h after CLP surgery, slightly lower than that at 72 h after CLP surgery; the lipid peroxidation levels in mouse cells at 24 and 48 h after CLP surgery were significantly higher than those at 0, 6, 12, and 72 h after CLP surgery. Compared with those at 0 h after CLP surgery, the levels of I-A/I-E and CD80 in mouse cells at 6, 12, 24, 48, and 72 h after CLP surgery and the levels of CD86 in mouse cells at 12, 24, and 48 h after CLP surgery were significantly increased ( P<0.05). At 24 h post-surgery, the protein expressions of TXNRD1, SLC7A11, and GPX4 in mouse cells in corn oil+CLP group were significantly lower than those in corn oil+sham injury group ( P<0.05), while the protein expressions of TXNRD1, SLC7A11, and GPX4 in mouse cells in inhibitor+CLP group were significantly lower than those in corn oil+CLP group and inhibitor+sham injury group ( P<0.05). At 24 h post-surgery, the content of GSH in mouse cells in corn oil+CLP group was (239±32) μg/mg, which was significantly lower than (366±59) μg/mg in corn oil +sham injury group ( P<0.05); the content of GSH in mouse cells in inhibitor+CLP group was (134±19) μg/mg, which was significantly lower than (355±31) μg/mg in inhibitor+sham injury group and that in corn oil+CLP group (with both P values <0.05). At 24 h post-surgery, the lipid peroxidation level of mouse cells in inhibitor+CLP group was significantly higher than that in the other three groups ( P<0.05). At 24 h post-surgery, the levels of I-A/I-E, CD80, and CD86 in mouse cells in corn oil+CLP group were significantly higher than those in corn oil+sham injury group ( P<0.05), while the levels of I-A/I-E and CD80 in mouse cells in inhibitor+CLP group were significantly higher than those in inhibitor+sham injury group ( P<0.05) but significantly lower than those in corn oil+CLP group ( P<0.05); the level of CD86 in mouse cells in inhibitor+sham injury group was significantly higher than that in corn oil+sham injury group ( P<0.05). Within 7 d post-surgery, the survival rate of mice in inhibitor+CLP group was significantly lower than that in inhibitor+sham injury group and corn oil+CLP group (with χ2 values of 31.19 and 3.91, respectively, both P values <0.05). Conclusions:In septic mice, the expression of TXNRD1 in DCs is reduced, cell ferroptosis is enhanced, and immune function is weakened. The inhibition of TXNRD1 in DCs will exacerbate cell ferroptosis and immune function suppression, and is closely related to the poor prognosis of sepsis.

Obesity is a major global public health challenge and a leading cause of multiple metabolic disorders,including hypertension and diabetes.In China,more than half of the adult population is overweight or obese.While anti-obesity pharmacotherapies(such as GLP-1 receptor agonists)and bariatric surgery have both advanced rapidly,strategies for integrating these two modalities remain unclear.In particular,controversies persist regarding surgical eligibility after drug discontinuation,and standardized clinical guidelines are lacking.In July 2025,the International Federation for the Surgery of Obesity and Metabolic Disorders released the world's first statement focusing on"metabolic bariatric surgery after pharmacotherapy-induced weight loss",which emphasizes the chronic disease model of obesity management and clarifies the synergistic relationship between pharmacotherapy and surgery.This article interprets the statement from the perspectives of treatment strategies,surgical eligibility,and drug-surgery coordination,aiming to provide evidence-based reference for clinicians and to promote standardized,integrated obesity management.
