Objective To explore the prognostic factors for patients with descending duodenum gastrointestinal stromal tumors (GIST), analyze the impact of different surgical approaches on prognosis, and develop a predictive model for surgical approach selection. Methods This single-center retrospective cohort study included patients with primary descending duodenum GIST treated in Zhongshan Hospital, Fudan University from January 2010 to January 2015, with follow-up until August 2025. The primary outcomes were incidence of postoperative complications, disease-free survival (DFS) rate, and overall survival (OS) rate. Cox regression and logistic regression were used to identify factors influencing prognosis and surgical approach selection, respectively. A nomogram model for selecting the surgical approach was constructed. Results A total of 78 patients with descending duodenum GIST were included, with age of (56.14±11.76) years. The 1-, 5-, and 10-year OS rates were 100%, 98.7%, and 85.7%, respectively, and the corresponding DFS rates were 100%, 90.9%, and 82.3%. Intraoperative blood loss, postoperative gastroparesis, mucosal ulceration, maximum tumor diameter, and Ki-67-positive cell ratio were independent risk factors for DFS, while maximum tumor diameter and mitotic figure were independent risk factors for OS (P＜0.05). The 10-year DFS rate was higher in the local resection group than in the pancreaticoduodenectomy group (89.45% vs 74.24%; HR＝0.300, P＝0.013), but there was no statistical difference in OS between the two groups. The incidence of postoperative complications in the pancreaticoduodenectomy group was higher than that in the local resection group (P＜0.001). Maximum tumor diameter and distance from tumor to the duodenal papilla were independent factors influencing surgical approach selection. The nomogram model based on these two indices demonstrated good discrimination and accuracy upon internal validation. Conclusions The long-term prognosis of patients with descending duodenal GIST is favorable, and surgical treatment achieves satisfactory outcomes. The nomogram model developed in this study can effectively guide individualized surgical approach selection and provide a reference for clinical decision-making.

Objective To compare the clinical efficacy of neuroendoscope-assisted evacuation and navigation-assisted puncture drainage in treating thalamic hemorrhage breaking into the ventricle. Methods A retrospective analysis was conducted on the clinical data of 93 patients with thalamic hemorrhage breaking into the ventricle at Taihe Hospital of Wannan Medical College between January 2022 and February 2024. The patients received neuroendoscope-assisted removal of thalamic hematoma combined with contralateral extraventricular drainage (n＝44, neuroendoscope group) and navigation-assisted thalamic hematoma puncture drainage combined with contralateral extraventricular drainage (n＝49, navigation group), respectively. The treatment efficacy, surgical situation, and prognosis between the two groups were compared. Results The neuroendoscope group had longer operation duration, more intraoperative blood loss, higher hospitalization costs than the navigation group (P＜0.05). The neuroendoscope group had higher hematoma clearance rate 3rd after surgery and shorter length of stay than the navigation group (P＜0.05). There was no significant difference in the incidence of intracranial infection after surgery between the two groups. The neuroendoscope group had higher Glasgow coma scale (GCS) score at 1 week after surgery and Glasgow outcome scale (GOS) score at 3 months after surgery (P＜0.01). Conclusions Compared with navigation-assisted puncture, neuroendoscope-assisted evacuation can improve the thalamic hemorrhage clearance rate, shorten the length of stay, and improve the prognosis of patients.

ObjectiveTo investigate the current professional competency among full-time and part-time personnel of the nosocomial infection control administration in Shanghai, so as to provide a scientific basis for future training programmes. MethodsIn December 2024, a questionnaire survey was conducted by the Shanghai Nosocomial Infection Quality Control Center among full-time and part-time personnel of the nosocomial infection control administration across medical institutions at various levels and types in Shanghai using convenience sampling method. The questionnaire consisted of two parts: demographic information and professional competency assessment. The professional competency scale comprised four dimensions: fundamental cognition, basic skills, professional expertise, and personal qualities, totaling 35 items. ResultsA total of 1 179 questionnaires were distributed, with 1 144 valid responses collected, yielding an effective response rate of 97.03%. Statistically significant differences were observed among full-time and part-time personnel of the nosocomial infection control administration in terms of age (t=5.32, P=0.021), professional background (χ²=9.90, P=0.019), educational qualifications (χ²=19.10, P<0.001), professional titles (χ²=12.60, P=0.002), and the levels of medical institutions (χ²=111.08, P<0.001). The scores of full-time personnel of the nosocomial infection control administration in fundamental cognition [92 (82, 99) points] and basic skills [88 (78, 96) points] were significantly higher than those of part-time personnel(Z=-2.21, P=0.027;Z=-2.74, P=0.006). Statistically significant differences were found in fundamental cognition scores between full-time and part-time personnel of the nosocomial infection control administration regarding occupational safety protection, definition of healthcare-associated infection outbreaks, types of drug-resistant bacteria and their prevention and control strategies, and transmission routes of different infectious diseases (all P<0.05). Statistically significant differences were also observed in basic skills scores including proficient use of monitoring platforms, formulation and revision of standard operating procedures (SOPs), independent completion of targeted surveillance, guidance on basic infection control skills, guidance for key departments, and follow-up of personnel with occupational exposure (all P<0.05). However, no statistically significant differences were found in scores of professional knowledge and personal qualities (P>0.05). ConclusionThere are certain differences in professional competency between full-time and part-time personnel of the nosocomial infection control administration in Shanghai in terms of fundamental cognition and basic skills. Part-time personnel can effectively improve their professional competency through systematic training on basic infection control knowledge and practical skills, thereby comprehensively enhancing the overall quality of the nosocomial infection administration team.

Objective To investigate the protective effect and underlying mechanisms of HydroMg, a novel sustained-release hydrogen donor, in a model of doxorubicin (DOX)-induced chronic cardiotoxicity. Methods H9C2 cells were treated with 1 μmol/L DOX and/or 1 μg/mL HydroMg, and mitochondrial membrane potential, reactive oxygen species (ROS) levels, and apoptosis were measured. In the animal experiment, mice were divided into control, HydroMg, DOX, and DOX＋HydroMg groups. The HydroMg group received intraperitoneal injection of HydroMg (100 mg/kg). Chronic cardiotoxicity was established by intraperitoneal injection of DOX (5 mg/kg every week) for four consecutive weeks; In the DOX＋HydroMg group, HydroMg (100 mg/kg) was administered intraperitoneally 4–5 h prior to each DOX injection. Cardiac function and remodeling were evaluated by echocardiography and heart weight index (HWI). The long-term survival of mice were analyzed. Subsequently, transcriptome sequencing was performed on myocardial tissues from the DOX group to identify key molecular alterations compared with controls. Results At the cellular level, HydroMg treatment effectively reversed DOX-induced mitochondrial dysfunction and oxidative stress, as evidenced by restored membrane potential, reductions in total ROS and mitochondrial superoxide levels by approximately 30% and 9%, respectively, and a decrease in the apoptosis rate from 34.13% to 18.27%. In the animal model, compared with the DOX group, HydroMg intervention increased left ventricular ejection fraction (LVEF) and fractional shortening (LVFS) by 9.62% and 5.82%, respectively, attenuated the reduction in HWI (4.41 mg/mm vs 3.53 mg/mm), and improved the 4-week survival rate (80% vs 60%). Transcriptomic analysis revealed that the core molecular features of DOX-induced cardiotoxicity, including widespread suppression of oxidative phosphorylation and antioxidant pathways. Conclusions HydroMg protects against DOX-induced chronic cardiotoxicity by alleviating oxidative stress and improving mitochondrial function, and provides a potential therapeutic strategy against DOX-related cardiotoxicity.

Objective To explore the application and efficacy of glucocorticoids in severe non-antineoplastic drug-induced liver injury (DILI). Methods A retrospective study was conducted on patients with severe non-antineoplastic DILI who were hospitalized at Zhongshan Hospital, Fudan University from November 2016 to October 2025. Clinical data, laboratory results, suspected causative drugs, glucocorticoid use, and prognosis were collected. The time for peak total bilirubin decreased by 50% was used as an efficacy indicator. Patients were divided into a glucocorticoid group and a non-glucocorticoid group based on glucocorticoid use. Results A total of 102 patients with severe DILI were included, and 58 (56.9%) received glucocorticoid therapy. The most common suspected causative drugs were traditional Chinese medicine (65.7%), and the primary type of liver injury was hepatocellular (72.5%). The proportion of female patients (P＝0.030), baseline peak total bilirubin (P＜0.001), and international normalized ratio (P＝0.034) were significantly higher in the glucocorticoid group than in the non-glucocorticoid group. The median time for peak total bilirubin decreased by 50% was 9.5 days in the glucocorticoid group and 11 days in the non-glucocorticoid group, with no statistically significant difference between the two groups. No significant benefit of glucocorticoid therapy was observed in subgroups with positive autoantibodies, elevated immunoglobulin G (IgG), or elevated γ-globulin ratio. Low-dose and gradual tapering were the main methods of glucocorticoid administration. Adverse reactions occurred in 8 patients (13.8%) in the glucocorticoid group, which resolved after drug withdrawal or symptomatic treatment. Conclusions The usage rate of glucocorticoids is relatively high in patients with severe non-antineoplastic DILI. Glucocorticoid treatment may accelerate the improvement of cholestasis in these patients, with mild adverse reactions and good safety.

Moyamoya vasculopathy (MMV) refers to a chronic cerebrovascular disease characterized by progressive stenosis or occlusion of the arteries around the circle of Willis, accompanied by the formation of collateral vessels. In traditional Chinese medicine (TCM), MMV falls into the categories of “stroke”, “vertigo”, and “headache”, among others. Its core etiology is related to congenital insufficiency and acquired malnourishment, with wind, fire, phlegm, deficiency, and stasis as the key pathogenic factors. Current Western medical diagnosis and treatment of MMV remain suboptimal, and TCM pattern differentiation has yet to be standardized. The most common clinical patterns are liver yang hyperactivity (associated with hemorrhagic symptoms) and qi deficiency with blood stasis (associated with ischemic symptoms). Treatment modalities include acupuncture, Chinese herbal formulas, and TCM–Western medicine integrated therapy. Clinical trial results have confirmed that integrated therapy offers certain benefits for MMV; however, there is a lack of relevant diagnostic and treatment guidelines as well as in-depth mechanistic studies. This article reviews the progress in TCM and Western medicine for the diagnosis and treatment of MMV and proposes a trinity diagnostic and therapeutic approach integrating “disease differentiation–pattern differentiation–staging”, which provides a reference for TCM–Western medicine integration management.

Objective To investigate the predictive value of D-dimer for in-hospital mortality and heart failure with reduced ejection fraction (HFrEF) in patients with acute myocardial infarction (AMI). Methods A total of 688 patients with AMI who were hospitalized at Zhongshan Hospital, Fudan University, from January 2020 to December 2023 were retrospectively enrolled. Demographic and clinical characteristics, laboratory findings, echocardiographic parameters, and in-hospital outcomes were collected. Patients were divided into four groups according to D-dimer quartiles, and trend tests were used to compare changes in each indicator with increasing D-dimer levels. The primary endpoints were in-hospital mortality and HFrEF. Multivariable logistic regression analysis was performed to assess the independent associations of D-dimer with in-hospital mortality and HFrEF. Receiver operating characteristic (ROC) curve analysis was used to evaluate its predictive performance. Results Differences and trend tests among four groups for age, creatinine, peak cardiac troponin T, N-terminal pro-brain natriuretic peptide (NT-proBNP), left ventricular ejection fraction, HFrEF incidence, and in-hospital mortality were statistically significant (P＜0.05). Multivariable logistic regression analysis showed that elevated D-dimer was associated with an increased risk of in-hospital mortality in patients with AMI (OR＝1.251, 95%CI 1.093–1.432, P＝0.001), and HFrEF (OR＝1.075, 95%CI 1.028–1.124, P＝0.002). ROC curve analysis showed that the area under the curve (AUC) of D-dimer for predicting in-hospital mortality and HFrEF were 0.871 and 0.716, respectively. At a cutoff value of 0.47 mg/L, the sensitivity and specificity of D-dimer in predicting HFrEF were 81.9% and 52.1%, respectively; at a cutoff value of 2.18 mg/L, the sensitivity and specificity of D-dimer in predicting in-hospital mortality were 63.6% and 93.8%, respectively. Restricted cubic spline analysis demonstrated significant non-linear associations between D-dimer and the risks of in-hospital mortality and HFrEF (P＜0.001). Conclusions Elevated D-dimer level is significantly associated with increased risks of in-hospital mortality and HFrEF in patients with AMI and shows acceptable predictive performance. As a simple and readily available laboratory biomarker, D-dimer may provide useful information for early risk stratification and clinical management in patients with AMI.
