Esophageal cancer is a prevalent malignant tumor of the digestive tract in China, and radical surgery remains the cornerstone of its comprehensive treatment. However, multifactorial challenges such as postoperative gastrointestinal tract reconstruction, traumatic stress, and tumor-related metabolic disturbances render esophageal cancer patients highly susceptible to malnutrition. Perioperative nutritional support therapy plays a crucial role in enhancing surgical safety, improving clinical outcomes, and elevating patients' quality of life by regulating metabolic homeostasis, preserving organ function, and optimizing the immune microenvironment. This article reviews the mechanisms underlying malnutrition in esophageal cancer, methods for nutritional status assessment, and precision intervention pathways based on multi-omics evaluations. The aim is to strengthen clinicians' awareness of standardized perioperative nutritional management for esophageal cancer patients and promote its clinical implementation, thereby facilitating postoperative recovery and improving long-term quality of life.

Background: s/Aims: Sarcomatoid hepatocellular carcinoma (HCC) is a rare histological subtype of HCC characterized by extremely poor prognosis; however, its molecular characterization has not been elucidated. Methods: In this study, we conducted an integrated multiomics study of whole-exome sequencing, RNA-seq, spatial transcriptome, and immunohistochemical analyses of 28 paired sarcomatoid tumor components and conventional HCC components from 10 patients with sarcomatoid HCC, in order to identify frequently altered genes, infer the tumor subclonal architectures, track the genomic evolution, and delineate the transcriptional characteristics of sarcomatoid HCCs. Results: Our results showed that the sarcomatoid HCCs had poor prognosis. The sarcomatoid tumor components and the conventional HCC components were derived from common ancestors, mostly accessing similar mutational processes. Clonal phylogenies demonstrated branched tumor evolution during sarcomatoid HCC development and progression. TP53 mutation commonly occurred at tumor initiation, whereas ARID2 mutation often occurred later. Transcriptome analyses revealed the epithelial–mesenchymal transition (EMT) and hypoxic phenotype in sarcomatoid tumor components, which were confirmed by immunohistochemical staining. Moreover, we identified ARID2 mutations in 70% (7/10) of patients with sarcomatoid HCC but only 1–5% of patients with non-sarcomatoid HCC. Biofunctional investigations revealed that inactivating mutation of ARID2 contributes to HCC growth and metastasis and induces EMT in a hypoxic microenvironment. Conclusions We offer a comprehensive description of the molecular basis for sarcomatoid HCC, and identify genomic alteration (ARID2 mutation) together with the tumor microenvironment (hypoxic microenvironment), that may contribute to the formation of the sarcomatoid tumor component through EMT, leading to sarcomatoid HCC development and progression.

Background/Aims: Metabolic dysfunction-associated steatohepatitis (MASH) is a significant risk factor for gallstone formation, but mechanisms underlying MASH-related gallstone formation remain unclear. Golgi membrane protein 1 (GOLM1) participates in hepatic cholesterol metabolism and is upregulated in MASH. Here, we aimed to explore the role of GOLM1 in MASH-related gallstone formation. Methods: The UK Biobank cohort was used for etiological analysis. GOLM1 knockout (GOLM1-/-) and wild-type (WT) mice were fed with a high-fat diet (HFD). Livers were excised for histology and immunohistochemistry analysis. Gallbladders were collected to calculate incidence of cholesterol gallstones (CGSs). Biles were collected for biliary lipid analysis. HepG2 cells were used to explore underlying mechanisms. Human liver samples were used for clinical validation. Results: MASH patients had a greater risk of cholelithiasis. All HFD-fed mice developed MASH, and the incidence of gallstones was 16.7% and 75.0% in GOLM1-/- and WT mice, respectively. GOLM1-/- decreased biliary cholesterol concentration and output. In vivo and in vitro assays confirmed that GOLM1 facilitated cholesterol efflux through upregulating ATP binding cassette transporter subfamily G member 5 (ABCG5). Mechanistically, GOLM1 translocated into nucleus to promote osteopontin (OPN) transcription, thus stimulating ABCG5-mediated cholesterol efflux. Moreover, GOLM1 was upregulated by interleukin-1β (IL-1β) in a dose-dependent manner. Finally, we confirmed that IL-1β, GOLM1, OPN, and ABCG5 were enhanced in livers of MASH patients with CGSs. Conclusions In MASH livers, upregulation of GOLM1 by IL-1β increases ABCG5-mediated cholesterol efflux in an OPN-dependent manner, promoting CGS formation. GOLM1 has the potential to be a molecular hub interconnecting MASH and CGSs.

Ménière's disease(MD)and vestibular migraine(VM)are two common episodic vertigo disor-ders.Patients with VM often exhibit auditory and vestibular symptoms similar to those of MD.Patients with MD are also prone to migraine features such as headache,photophobia,and a positive family history of migraine.There-fore,differentiating MD from VM is challenging,especially in the early stages of the disease.Although the two dis-eases overlap in many ways,some core features in terms of demographic characteristics,clinical symptoms,and la-boratory tests can be used to identify them.However,a highly specific test or biological marker to distinguish the two is not available.Physicians may combine various features such as symptoms,signs,and tests to differentiate MD and VM.

Aim To investigate the role and mecha-nism of allopurinol(ALLO)in restoring the abnormal metabolism of kynurenine(Kyn)mediated by trypto-phan-2,3-dioxygenase 2(TDO2)to ameliorate ulcera-tive colitis(UC)in mice,and to provide experimental basis for the treatment of UC by ALLO.Methods A dextran sodium sulfate(DSS)-induced mouse UC mod-el was established,and the mice were randomly divided into the control group,the model group,the ALLO low,medium and high-dose groups(10,20,and 40 mg·kg-1),and the positive-significant salazosulfapyridine(SASP)(200 mg·kg-1)group.The body mass and disease activity index(DAI)scores of mice were re-corded;HE staining was performed to observe the de-gree of pathological damage in colon tissue;Western blot was performed to detect TDO2 protein expression in colon tissue;flow cytometry was performed to detect changes in the proportion of macrophages in spleen and mesenteric lymph nodes;ELISA was employed to de-tect the levels of TNF-α,IL-1β and IL-6 pro-inflamma-tory cytokines in the supernatant of colon tissue homog-enate;high performance liquid chromatography(HPLC)was used to detect the levels of tryptophan(Trp)and Kyn in the supernatant of colon tissue ho-mogenate.Results Compared with the model group,ALLO administration significantly ameliorated colonic histopathological injury in UC mice,decreased the pro-portion of macrophages in spleen and mesenteric lymph nodes,down-regulated the levels of TNF-α,IL-1 β,and IL-6 pro-inflammatory factors in serum of homogenate of colonic tissues,and inhibited the activity(Kyn/Trp ratio)and expression of TDO2 in colonic tissues.Con-clusion ALLO improves disease manifestations in mice with ulcerative colitis,which may be related to its restoration of abnormal Kyn metabolism.

Aim To investigate the effect of Zhenwu decoction on inflammation,oxidative stress and apopto-sis of human glomerular epithelial cells(HGEC)in-duced by lipopolysaccharide(LPS)based on Nrf2/HO-1 signaling pathway,and to explore the underlying mechanism.Methods HGEC were treated with LPS(1.0 mg·L-1)for 24 h to construct an oxidative damage model.On this basis,2.5％,5％and 10％Zhenwu decoction-containing serum were added to the low,medium and high dose groups of Zhenwu decoc-tion,and a normal group was set up.The changes of cell activity were assessed by MTT method and LDH method.The contents of TNF-α,IL-6,IL-10,SOD,CAT,GSH-Px,ROS and MDA in each group were de-tected by ELISA.The apoptosis of each group was de-tected by flow cytometry.The mRNA and protein ex-pressions of Bax,Bcl-2,caspase-3,caspase-9 and Nrf2/HO-1 pathway were detected by RT-qPCR and Western blot,respectively.Results Compared to the normal group,the model group of HGEC exhibited increased levels of inflammatory cytokines,enhanced oxidative stress response and aggravated apoptosis;after inter-vention with various doses of Zhenwu decoction,the in-flammatory levels in HGEC were reduced,oxidative damage and apoptosis were effectively ameliorated,and the mRNA and protein expression levels of the Nrf2/HO-1 signaling pathway were upregulated.Conclu-sions Zhenwu decoction can protect HGEC from LPS-induced inflammation and oxidative damage and im-prove apoptosis.The mechanism may be related to the activation of Nrf2/HO-1 signaling pathway.

Objective:To explore the mediating role of coping style and fear of disease progression between health literacy and self-management in postoperative chemotherapy patients with colorectal cancer. It provided a theoretical basis for improving the self-management ability of postoperative chemotherapy patients with colorectal cancer.Methods:Convenience sampling method was used to select postoperative chemotherapy patients with colorectal cancer admitted to the Second Affiliated Hospital of Anhui Medical University from October 2023 to May 2024, and a cross-sectional survey was conducted using Health Literacy Management Scale, Medical Coping Modes Scale, Fear of Progression Questionnaire-Short Form, and Cancer Patient Self-Management Assessment Scale.Results:A total of 229 questionnaires were distributed, of which 220 were returned as valid questionnaires, including 142 males and 78 females, aged (60.05 ± 10.14) years. The total health literacy score was (85.30 ± 9.45) points and self-management score was (150.36 ± 14.10) points among patients undergoing postoperative chemotherapy for colorectal cancer. Self-management was positively correlated with health literacy and facing ( r=0.576, 0.525, both P<0.01), while negatively correlated with avoidance, yielding, and fear of disease progression ( r=-0.660, -0.616, -0.566, all P<0.01). The mediation model showed that facing coping style and fear of disease progression had a chained mediation effect of 0.050 between health literacy and self-management, accounting for 8.36% of the total effect. Conclusions:Self-management in patients with postoperative chemotherapy for colorectal cancer was moderately low. The chain mediating role of coping style and fear of disease progression between health literacy and self-management in postoperative chemotherapy patients with colorectal cancer was established. Nursing staff should strengthen health education for postoperative chemotherapy patients with colorectal cancer, guide patients to face the disease positively, reduce fear, and promote patient self-management.

Objective:To construct Nomogram prediction model for pulmonary infection in patients after aortic dissection surgery, so as to provide reference for early screening of high-risk groups and carrying out preventive nursing measures.Methods:This was a retrospective case-control study. The case data of patients after aortic dissection surgery in the Second Affiliated Hospital of Anhui Medical University from January 2020 to October 2023 were selected by convenient sampling method and divided into pulmonary infection group and non-pulmonary infection group according to whether pulmonary infection occurred within one week after surgery. The risk factors of pulmonary infection after aortic dissection surgery were analyzed by Logistic regression and the Nomogram prediction model was constructed by R4.3.3.The model was evaluated by area under the receiver operating characteristic curve, calibration curve and decision curve analysis.Results:A total of 324 patients with aortic dissection were collected, and the incidence of postoperative pulmonary infection was 26.9%(87/324). There were 87 cases in pulmonary infection group, including 65 males and 22 females, with a median age of 58.0 years. There were 237 cases in non-pulmonary infection group, including 180 males and 57 females, with a median age of 60.0 years. Finally, operation time ( OR=1.015, 95% CI 1.007-1.022), intraoperative blood transfusion ( OR=1.001, 95% CI 1.000-1.022), mechanical ventilation time ( OR=7.624, 95% CI 2.679-21.692), postoperative invasive operation ( OR=6.310, 95% CI 1.545-25.778) and postoperative renal insufficiency ( OR=6.723, 95% CI 1.219-37.063) were independent risk factors for pulmonary infection after aortic dissection surgery. The area under the receiver operating characteristic curve of the model was 0.978, sensitivity of 93.7%, and specificity of 90.8%. The calibration curve showed good consistency, and the decision curve analysis curve showed good net benefit. Conclusions:Operation time, intraoperative blood transfusion, mechanical ventilation time, postoperative invasive operation and postoperative renal insufficiency are high-risk factors of pulmonary infection after aortic dissection surgery and the constructed predictive model has predictive value.

Objective:To evaluate the efficacy and safety of therapeutic temperature control in patients with severe traumatic brain injury (sTBI).Methods:The full-text databases of Chinese Medical Journal, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP Database, China Biomedical Database, PubMed, Embase, and Cochrane Library were searched for randomized controlled trials (RCTs) of hypothermia treatment and conventional treatment in patients with sTBI. The search period was from January 2016 to June 2025. Meta-analysis was performed using RevMan 5.3 software. The evaluation indicators included intracranial pressure before treatment, at 3 and 5 days after treatment, favorable prognosis rate and mortality rate within 6 months after treatment, and incidence of pulmonary infection, intracranial infection, epilepsy, acute gastrointestinal dysfunction, deep vein thrombosis, abnormal coagulation function, and arrhythmia during treatment; publication bias.Results:A total of 33 studies involving 3 322 patients were included, with 1 696 patients in the temperature treatment group and 1 626 in the conventional treatment group. There was no statistically significant difference in intracranial pressure between the two groups before treatment ( SMD=0, 95% CI -0.13, 0.14, P>0.05). However, at 3 and 5 days after treatment, the intracranial pressure was lower in the temperature treatment group than that in the conventional treatment group ( SMD=-2.29, 95% CI -2.76, -1.82, P<0.01; SMD=-2.66, 95% CI -3.43, -1.89, P<0.01). Within 6 months after treatment, the favorable prognosis rate was higher in the temperature treatment group than that in the conventional treatment group ( RR=1.41, 95% CI 1.32, 1.50, P<0.01), and mortality rate was lower than that in the conventional treatment group ( RR=0.64, 95% CI 0.55, 0.75, P<0.01). Compared with the conventional treatment group, the incidences of epilepsy and acute gastrointestinal dysfunction in the temperature treatment group were statistically reduced ( RR=0.33, 95% CI 0.13, 0.83, P<0.05; RR=0.43, 95% CI 0.25, 0.74, P<0.05). There were no statistically significant differences in the incidence of pulmonary infection ( RR=0.96, 95% CI 0.85, 1.08, P>0.05), intracranial infection ( RR=0.56, 95% CI 0.20, 1.56, P>0.05), deep vein thrombosis ( RR=0.93, 95% CI 0.69, 1.25, P>0.05), abnormal coagulation function ( RR=1.19, 95% CI 0.43, 3.31, P>0.05) or arrhythmia ( RR=0.51, 95% CI 0.23, 1.12, P>0.05) between the two groups. Egger′s test indicated the presence of publication bias and the results remained robust after trim and fill analysis. Conclusions:For patients with sTBI, temperature control therapy shows lowered intracranial pressure and mortality rate as well as improved favorable prognosis rate at 6 months posttreatment, and decreased incidence of epilepsy and acute gastrointestinal dysfunction during treatment, while reveals similar incidence of pulmonary infection, intracranial infection, deep vein thrombosis, abnormal coagulation function, and arrhythmia when compared with conventional treatment.

Objective:To investigate the clinical management,complications,and prognostic prediction model of bronchopulmonary dysplasia(BPD)in preterm infants.Methods:A total of 854 very preterm infants(gestational age ≤ 32 weeks)admitted to the Neonatal Intensive Care Unit(NICU)of Shanghai Children's Hospital from January 2018 to December 2022 were retrospectively enrolled.After applying inclusion and exclusion criteria,713 infants were included.Based on the 2018 National Institute of Child Health and Human Development(NICHD)diagnostic criteria for BPD,the cohort was divided into a BPD group(n=164)and a non-BPD group(n=549).Clinical data of infants and maternal characteristics were compared between groups.Univariate and stepwise multivariate logistic regression analyses were performed to identify independent risk factors for BPD and evaluate clinical management.A nomogram model was subsequently developed to predict BPD prognosis.Results:Gestational age,duration of non-invasive ventilation,total oxygen therapy time,total hospital stay,hemodynamically significant patent ductus arteriosus(hsPDA),maximum diameter of patent ductus arteriosus(PDA),fetal growth restriction(FGR),use of vasoactive agents,and proportion of pulmonary surfactant administration were identified as independent risk factors for BPD(all P＜0.05,OR＞0).The nomogram model demonstrated excellent predictive performance,with an area under the receiver operating characteristic curve(AUC)of 0.93 and a calibration curve slope approaching 1.The Hosmer-Lemeshow goodness-of-fit test indicated satisfactory model calibration(x2=8.2865,P=0.406).Conclusion:Gestational age,non-invasive ventilation duration,total oxygen therapy time,total hospital stay,hsPDA,PDA maximum diameter,FGR,vasoactive agents,and pulmonary surfactant use are critical predictors of BPD in preterm infants.The prognostic models for BPD incidence and severity,constructed based on these factors,exhibit strong predictive accuracy and may serve as a valuable clinical tool for risk stratification and early intervention.
