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.

Lung cancer remains one of the leading causes of cancer-related morbidity and mortality worldwide, and its treatment continues to face major challenges such as therapeutic resistance and tumor recurrence. Pyroptosis, a newly characterized form of programmed cell death, induces tumor cell death through gasdermin-mediated membrane pore formation and is accompanied by the release of inflammatory mediators, thereby playing complex roles in lung cancer initiation, progression, and modulation of the tumor microenvironment. Active components and herbal formulas derived from traditional Chinese medicine can modulate pyroptosis-related signaling pathways through multi-target mechanisms, showing potential advantages in inducing lung cancer cell death, inhibiting proliferation and migration, and reversing chemoresistance. This review systematically summarizes relevant studies from domestic and international sources, focusing on the molecular mechanisms of pyroptosis, its roles in lung cancer development and tumor microenvironment remodeling, and the current research progress on traditional Chinese medicine-based interventions targeting pyroptosis, with the aim of providing references for the prevention and treatment of lung cancer using traditional Chinese medicine.

ObjectiveThe present study aimed to investigate alterations in white matter microstructure and spontaneous neural activity in male college smokers, and to further explore their associations with nicotine dependence. Given that adolescence and early adulthood represent critical periods for brain maturation, particularly for white matter development, understanding the neural correlates of smoking behavior during this stage is of substantial importance for both neuroscience and public health. MethodsA total of 115 male undergraduate students were initially recruited for this study. After quality control and exclusion procedures, 52 male college smokers and 42 demographically matched healthy non-smokers were included in the final analysis. All participants underwent multimodal magnetic resonance imaging (MRI), including diffusion tensor imaging (DTI) and resting-state functional MRI (rs-fMRI). White matter fiber tracts were reconstructed using the automated fiber quantification (AFQ) method, which enables precise identification and quantification of major fiber bundles. Eighteen major white matter tracts were segmented for each participant. Along the core trajectory of each tract, 100 equidistant nodes were sampled. Fractional anisotropy (FA) was calculated at each node to assess white matter microstructural integrity, while amplitude of low-frequency fluctuation (ALFF) was computed to evaluate spontaneous neural activity within white matter tracts. Between-group differences in FA and ALFF were assessed using two-sample t-tests, with appropriate corrections applied for multiple comparisons. Furthermore, Pearson correlation analyses were conducted to examine the relationships between imaging-derived metrics (FA and ALFF values in regions showing significant group differences) and nicotine dependence severity, as measured by the Fagerström test for nicotine dependence (FTND). ResultsCompared with healthy non-smokers, male college smokers exhibited significantly increased FA values in several white matter tracts, including the left thalamic radiation, right corticospinal tract, forceps major of the corpus callosum, left uncinate fasciculus, and right arcuate fasciculus. These findings suggest altered microstructural organization or increased directional coherence within these pathways. In addition, smokers demonstrated significantly elevated ALFF values in the forceps major, right uncinate fasciculus, and left arcuate fasciculus, indicating enhanced spontaneous neural activity in these white matter regions. Correlation analyses revealed that FA values in the left thalamic radiation and right corticospinal tract were negatively correlated with FTND scores, suggesting that higher levels of nicotine dependence were associated with reduced microstructural integrity or altered fiber organization in these regions. In contrast, ALFF values in the forceps major and right uncinate fasciculus were positively correlated with FTND scores, indicating that greater nicotine dependence was associated with increased spontaneous neural activity in specific white matter pathways. ConclusionThe present study provides evidence that male college smokers exhibit distinct alterations in both white matter microstructure and functional activity. These abnormalities are not uniformly distributed but rather localized to specific fiber tracts implicated in sensorimotor processing, interhemispheric communication, and higher-order cognitive and emotional regulation. Importantly, the observed associations between imaging metrics and nicotine dependence severity suggest that these structural and functional alterations may reflect neurobiological mechanisms underlying addiction. The combination of AFQ-based tract profiling and multimodal MRI offers a sensitive approach for detecting subtle changes along white matter pathways, highlighting its potential utility in identifying neuroimaging biomarkers of nicotine dependence. Overall, these findings indicate that smoking during early adulthood may disrupt ongoing white matter maturation, potentially leading to long-term consequences for brain function. This study provides novel insights into the neural basis of nicotine dependence and underscores the importance of early intervention and prevention strategies targeting young smokers.

ObjectiveTo explore the mechanisms of Qingchang Wenzhong Decoction (清肠温中方, QWD) in treating ulcerative colitis (UC). MethodsA total of 100 male C57BL/6J mice were assigned to a pseudo-germ-free group (n=45) and a conventional group (n=55) using a random number table. Pseudo-germ-free model was established by giving antibiotic treatment and subsequently subjected to acute UC induction. After the model was successfully established, the 45 pseudo-germ-free acute UC mice were randomly allocated to a pseudo-germ-free model group, a pseudo-germ-free QWD group, and a pseudo-germ-free mesalazine group, with 15 mice in each group. The 55 conventional mice were randomly divided into a normal control group (n=10), as well as a conventional model group, a conventional QWD group, and a conventional mesalazine group, with 15 mice in each group. Except for the normal control group, acute UC models were established in all other groups. Mice in the control group received no intervention. From day 32 of the experiment, mice in the pseudo-germ-free QWD group and the conventional QWD group were administered with QWD granules at a dose of 9.71 g/(kg·d) by gavage with deionized water, while those in the pseudo-germ-free mesalazine group and the conventional mesalazine group were given mesalazine enteric-coated tablets at a dose of 151.67 mg/(kg·d) by gavage. Mice in the remaining groups received an equal volume of deionized water once daily for 7 consecutive days. On day 25 of the experiment, six mice were randomly selected from both the pseudo-germ-free group and the conventional group to measure body weight, and fecal samples were collected for 16S rDNA sequencing to compare differences in gut microbiota, including operational taxonomic units (OTUs), Shannon index, Observed_species index, and phylogenetic diversity (PD whole tree). On day 39, body weight was measured in all groups, and the disease activity index (DAI) was evaluated. Colon length and colon wet weight were recorded. Histopathological changes in colonic tissues were assessed by hematoxylin and eosin (HE) staining, and histological injury scores were determined. In addition, the expression levels of mucopolysaccharides and mucin 2 (MUC2) in colonic tissues were measured. ResultsOn day 25, there was no significant difference in body weight between the pseudo-germ-free group and the conventional microbiota group (P>0.05). Compared to the conventional microbiota group, the pseudo-germ-free group showed significantly reduced OTUs, Shannon index, Observed_species index, and PD whole tree (P<0.01). On day 39, compared to the normal control group, mice in the conventional model group showed a significant decrease in the body weight and an increase in DAI, along with increased colon wet weight, shortened colon length, markedly elevated histopathological scores, and reduced expression of mucopolysaccharides and MUC2 (P<0.01). In contrast, no significant differences were observed in these parameters in the pseudo-germ-free model group (P>0.05). Compared to the conventional model group, the conventional QWD group showed significant improvement in all measured parameters, whereas the conventional mesalazine group showed reductions only in DAI scores and colon wet weight (P<0.01). No statistically significant differences were observed among the pseudo-germ-free model group, the pseudo-germ-free QWD group, and the pseudo-germ-free mesalazine group (P>0.05). ConclusionQWD may promote the reconstruction of the intestinal mucus barrier by regulating the intestinal flora, thereby exerting a therapeutic effect on acute UC.

Objective:To translate the Maastricht Clinical Teaching Questionnaire (MCTQ) into Chinese and evaluate its reliability and validity in standardized training of residents.Methods:The Chinese version of MCTQ was obtained according to the Brislin translation model, including translation, back-translation, and cross-cultural debugging. A convenient sampling survey was carried out among the trainees in the First Affiliated Hospital of Shandong First Medical University in June 2022 by using an online survey tool. A total of 562 valid questionnaires were collected. Data from valid survey questionnaires were subjected to item analysis (critical ratio method), reliability analysis (Cronbach's alpha coefficient and composite reliability), structural validity analysis (exploratory factor analysis and confirmatory factor analysis), and discriminant validity analysis using SPSS 25.0 and AMOS 24.0 software.Results:The Chinese version of MCTQ scale consisted of 24 items, which was consistent with the original scale. Four common factors were extracted with a cumulative variance contribution of 79.96%. The four-factor model demonstrated high goodness of fit. The χ2/d f, RMR, RMSEA, GFI, AGFI, NFI, and CFI were 3.491, 0.008, 0.067, 0.886, 0.861, 0.947, and 0.962, respectively. Both Cronbach's α and composite reliability exceeded 0.7, indicating high internal consistency and reliability. The correlation coefficients between the four factors ranged from 0.265 to 0.307, all of which were smaller than the corresponding square roots of average variance extracted, demonstrating high structural and discriminant validity. Conclusions:The Chinese version of MCTQ is valid and reliable in the Chinese context and can serve as a useful tool to evaluate the performance of clinical teachers during standardized residency training.
