Hepatocellular carcinoma(HCC), the third leading cause of cancer-related death worldwide, is characterized by high mortality and recurrence rates. Common treatments include hepatectomy, liver transplantation, ablation therapy, interventional therapy, radiotherapy, systemic therapy, and traditional Chinese medicine(TCM). While exhibiting specific advantages, these approaches are associated with varying degrees of adverse effects. To alleviate patients' suffering and burdens, it is crucial to explore additional treatments and elucidate the pathogenesis of HCC, laying a foundation for the development of new TCM-based drugs. With emerging research on gut microbiota, it has been revealed that microbiota plays a vital role in the development of HCC by influencing intestinal barrier function, microbial metabolites, and immune regulation. TCM, with its multi-component, multi-target, and multi-pathway characteristics, has been increasingly recognized as a vital therapeutic treatment for HCC, particularly in patients at intermediate or advanced stages, by prolonging survival and improving quality of life. Recent global studies demonstrate that TCM exerts anti-HCC effects by modulating gut microbiota, restoring intestinal barrier function, regulating microbial composition and its metabolites, suppressing inflammation, and enhancing immune responses, thereby inhibiting the malignant phenotype of HCC. This review aims to elucidate the mechanisms by which gut microbiota contributes to the development and progression of HCC and highlight the regulatory effects of TCM, addressing the current gap in systematic understanding of the "TCM-gut microbiota-HCC" axis. The findings provide theoretical support for integrating TCM with western medicine in HCC treatment and promote the transition from basic research to precision clinical therapy through microbiota-targeted drug development and TCM-based interventions.

Doxorubicin (Dox) is an anthracycline drug widely applied in various malignancies. However, the fatal cardiotoxicity induced by Dox limits its clinical application. Post-transcriptional protein modification via ubiquitination/deubiquitination in cardiomyocytes mediates the pathophysiological process in Dox-induced cardiotoxicity (DIC). In this study, we aimed to clarify the regulatory role and mechanism of a deubiquitinating enzyme, ubiquitin-specific peptidase 13 (USP13), in DIC. RNA-seq analysis and experimental examinations identified that cardiomyocyte-derived USP13 positively correlated with DIC. Mice with cardiac-specific deletion of USP13 were subjected to Dox modeling. Adeno-associated virus serotype 9 (AAV9) carrying cTNT promoter was constructed to overexpress USP13 in mouse heart tissues. Cardiomyocyte-specific knockout of USP13 exacerbated DIC, while its overexpression mitigated DIC in mice. Mechanistically, USP13 deubiquitinates the stimulator of interferon genes (STING) and promotes the autolysosome-related degradation of STING, subsequently alleviating cardiomyocyte inflammation and death. Our study suggests that USP13 serves a cardioprotective role in DIC and indicates USP13 as a potential therapeutic target for DIC treatment.

Objective:To investigate the current situation of fall fear in elderly patients after operation of intertrochanteric fracture, analyze the influencing factors and build a prediction model.Methods:A prospective cohort study and convenient sampling method were used to select 303 elderly patients with intertrochanteric fracture after surgery in the Department of Orthopedics, Affiliated Hospital of Jining Medical University from January 2021 to December 2022 as the modeling group. According to the scores of fall fear when getting out of bed for the first time, they were divided into 211 cases in the fall fear group and 92 cases in the non-fall fear group. Multivariate Logistic regression was used to analyze the influencing factors of fall fear after operation of femoral intertrochanteric fracture in elderly patients, and a risk prediction score model was established. ROC curve was used to evaluate the differentiation of the model, calibration chart was used to evaluate the calibration degree of the model, and Bootstrap method was used for internal verification. Data of 81 elderly patients with intertrochanteric fracture treated from January to May 2023 were collected as a validation set for external verification of the model.Results:A total of 6 influencing factors were included in the prediction of fall fear risk model for elderly patients after operation of intertrochanteric fracture: gender ( OR = 3.229, 95% CI 1.672 - 6.401), number of co-existing diseases ( OR = 9.578, 95% CI 4.532 - 20.245), pain ( OR = 1.684, 95% CI 1.074 - 2.463), depression ( OR = 1.719, 95% CI 1.371 - 2.155), social support ( OR = 0.859, 95% CI 0.784 - 0.942), and ability to perform activities of daily living ( OR = 0.960, 95% CI 0.932 - 0.989) (all P<0.05). The area under ROC curve of the prediction model was 0.853, the sensitivity was 0.896, and the specificity was 0.663. The area under the externally verified ROC curve was 0.766, the sensitivity was 0.800, and the specificity was 0.645. The calibration curve was close to the reference curve in the model prediction, indicating that the model hasd a good prediction effect. Conclusions:The prediction effect of this model is good, and it can quickly predict the risk of fall fear in elderly patients after operation of intertrochanteric fracture, and provide a basis for medical personnel to provide timely intervention measures.
