ObjectiveTo investigate the value of preoperative dual-layer spectral detector CT （DLCT） parameters in predicting lymph node metastasis （LNM） of non-functional pancreatic neuroendocrine neoplasms （NF-pNENs）. MethodsA retrospective study was conducted on patients with pathologically confirmed NF-pNENs who underwent preoperative contrast-enhanced DLCT examination between September 2019 and July 2024. Regions of interest （ROIs） were manually delineated on three representative slices of the solid component of the lesion， and the mean values were recorded. Conventional CT parameters， monochromatic energy images （40 keV， 70 keV， 100 keV）， iodine concentration maps， and effective atomic number （Z_eff） maps in the pancreatic parenchymal phase and portal venous phase were acquired. A total of 34 parameters， including clinical characteristics， imaging features， conventional CT and DLCT quantitative parameters， were analyzed. Intergroup differences were compared between the LNM and non-LNM groups. Independent predictive factors were screened using logistic regression and least absolute shrinkage and selection operator （LASSO） regression. Receiver operating characteristic （ROC） curves were generated for each predictive model， and the area under the curve （AUC） was calculated to evaluate the predictive efficacy. ResultsA total of 82 patients with NF-pNENs were enrolled， including 37 males and 45 females， with a mean age of 49.7±14.7 years. Thirty patients were performed with LNM and 52 were with non-LNM. After univariate logistic regression， LASSO regression and multivariate stepwise logistic regression analyses， body mass index （BMI）， organ invasion， normalized CT value in the portal venous phase （nCTv） and normalized iodine concentration in the portal venous phase （nICv） were identified as independent predictive factors. The AUCs of the clinical-radiological qualitative model （BMI+organ invasion）， conventional CT model （nCTv）， DLCT model （nICv） and comprehensive model （organ invasion+nICv） were 0.815 （0.719， 0.910）， 0.750 （0.642， 0.858）， 0.829 （0.733， 0.925） and 0.865 （0.879， 0.953）， respectively. The comprehensive model combining clinical-radiological and DLCT characteristics exhibited superior predictive performance. ConclusionDLCT parameters are more effective than conventional CT parameters in predicting LNM in NF-pNENs， enabling non-invasive preoperative prediction and assisting clinical decision-making.

The hemostatic function in patients with liver cirrhosis is not simply in a state of hypocoagulability， but rather a fragile rebalanced state resulting from the simultaneous remodeling of procoagulant and anticoagulant systems， the von Willebrand factor-platelet axis， and the fibrinolytic system. Since patients with liver cirrhosis frequently exhibit laboratory abnormalities including thrombocytopenia， prolonged prothrombin time/international normalized ratio， abnormal fibrinogen level， and elevated D-dimer， these manifestations substantially overlap with the laboratory phenotype of disseminated intravascular coagulation （DIC）， leading to potential misdiagnosis and unnecessary blood product transfusion or correction of coagulation parameters in clinical practice. Current evidence suggests that factor Ⅷ level and the widely used International Society on Thrombosis and Haemostasis DIC scoring system have limited value in differential diagnosis in patients with liver disease， and there is still a lack of a unified pathway for differential diagnosis. This article systematically reviews the pathophysiological overlap between rebalanced hemostasis in liver cirrhosis and DIC and summarizes the diagnostic value of conventional coagulation parameters， emerging hemostatic biomarkers， and global hemostatic assays in differential diagnosis of these conditions. Furthermore， it proposes a four-step diagnostic pathway of “trigger identification， baseline comparison， dynamic monitoring， and organ assessment” with reference to the specific clinical scenarios including infection， acute decompensation， gastrointestinal bleeding， hepatocellular carcinoma， and the perioperative period. In the future， DIC prediction models based on the features of liver disease should be established in combination with viscoelastic testing and multidimensional biomarkers， so as to achieve precise risk stratification and individualized management of coagulation abnormalities in patients with liver cirrhosis.

The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

Objective:To assess the safety and to identify risk factors associated with systemic adverse effects (SAEs) during the dose-escalation phase of rush immunotherapy (RIT) in patients with allergic rhinitis (AR).Methods:A retrospective analysis was conducted in 316 house dust mite-allergic patients diagnosed with AR who underwent RIT at the Second Affiliated Hospital of Nanchang University between February 2012 and August 2024, including 206 males and 110 females aging from 5 to 58 years old. The number of patients experiencing SAEs, the frequency of SAE incidents, and the severity grades of SAEs during the dose-escalation phase were analyzed. Associations between SAE occurrence and 19 potential factors, including demographic characteristics, serological parameters, and pulmonary function parameters, were investigated. Data were analyzed using IBM SPSS Statistics version 26.0.Results:Among the 316 patients, 4 358 RIT injections were administered during the dose-escalation phase. SAEs occurred in 45 patients (14.24%, 45/316), accounting for 57 distinct SAE incidents. The SAE incidence rate per injection was 1.31%. Of the 57 SAEs, 34 (59.65%) were Grade Ⅰ, 5 (8.77%) were Grade Ⅱ, and 18 (31.58%) were Grade Ⅲ. No Grade Ⅳ or Ⅴ SAEs were observed. SAE occurrence demonstrated significant associations with: age ( Z=-2.73, P=0.006), body mass index (BMI; t=4.08, P<0.001), skin prick test reaction intensity ( χ2=10.34, P=0.006), eosinophil count ( Z=-2.19, P=0.028), eosinophil percentage ( Z=-2.59, P=0.010), forced expiratory volume in one second (FEV?; Z=-2.04, P=0.042), peak expiratory flow (PEF; Z=-2.44, P=0.015). Multivariate logistic regression analysis identified BMI as an independent risk factor for SAEs ( OR=0.86; 95% CI: 0.75-0.99; P=0.034). Conclusions:During the RIT dose-escalation phase for house dust mite-allergic AR patients, the incidence of SAEs was approximately 1.31% per injection. SAEs were predominantly mild (Grade Ⅰ), consistent with a favorable overall safety profile. BMI was identified as a statistically significant risk factor for SAE occurrence.

OBJECTIVES: To verify whether hesperetin (Hes) alleviates doxorubicin (DOX)-induced cardiotoxicity by reducing inflammation via regulating the AMPK/NLRP3 pathway. METHODS: C57/bl6 mice and H9c2 cells treated with DOX to mimic cardiotoxicity were randomly divided into Sham (or control) group, DOX group, DOX+Hes group, DOX+Hes+compound C (CC, an AMPK inhibitor) group. Cardiac function and myocardial pathologies of the mice were evaluated, and the changes in H9c2 cell morphology and viability were assessed. Lactate dehydrogenase (LDH) activity in mouse myocardial tissues and H9c2 cells was measured using ELISA, and H9c2 cell apoptosis was detected with TUNEL staining. In both H9c2 cells and the myocardial tissues of the mice, cellular expression levels of TNF-α, IL-6 and IL-1β mRNAs and cleaved caspase-3, Bcl2, Bax, IL-1β, IL-18, p-AMPK, AMPK, p-mTOR, mTOR, NLRP3, ASC and caspase-1 proteins were detected using RT-PCR and Western blotting. RESULTS: DOX treatment caused cell swelling, decreased cell viability and increased LDH activity in H9c2 cells, resulting also in significantly increased cell apoptosis and cleaved caspase-3 expression and decreased Bcl2/Bax ratio. The DOX-treated mice showed obvious myocardial fiber swelling and inflammatory infiltration, decreased cardiac function and significantly increased myocardial LDH activity. In H9c2 cells, DOX treatment significantly increased the mRNA expressions of TNF-α, IL-6 and IL-1β and protein expressions of IL-1β and IL-18, lowered the expressions of p-AMPK and p-mTOR, and increased the expressions of NLRP3, ASC and caspase-1. Hes treatment obviously reduced these toxic effects of DOX in H9c2 cells, but its protective effects were blocked by application of compound C. CONCLUSIONS Hes reduces DOX-induced cardiotoxicity by inhibiting inflammation via regulating the AMPK/NLRP3 pathway.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective:To assess the efficacy and safety profile of antaitasvir phosphate combined with yiqibuvir in the treatment of chronic hepatitis C (CHC) of various genotypes, without cirrhosis or with compensated cirrhosis.Methods:394 cases with CHC from 22 centers were collected from October 2021 to April 2023. They were randomly assigned to receive either the experimental drugs (antaitasvir phosphate 100 mg+yiqibuvir 600 mg) or placebo treatment in a 3∶1 ratio. The patients were administered drugs once a day for 12 consecutive weeks, and then followed up for 24 weeks after treatment cessation. All subjects were unblinded at the four-week follow-up following drug discontinuation, with the experimental drug group continuing to complete subsequent post-discontinuation follow-up. The placebo group was switched to receive the experimental drugs for a repeated 12-week treatment period and followed up for another 24 weeks after discontinuation of the drug (placebo delayed treatment phase).The sustained virologic response rate (SVR12) was observed for subjects in the double-blind phase and the placebo delayed-treatment phase at 12 weeks after treatment cessation.Virological resistance analysis was performed on subjects who failed treatment. The primary efficacy endpoint was SVR12. The number and percentage of subjects who achieved "HCV RNA
