As one of the most common malignant tumors， digestive system tumors exhibit an increase in the incidence and mortality year by year. Its pathogenesis is complex， making it difficult to carry out early prevention. Autophagy is a process in which cells use lysosomes to degrade their organelles and macromolecules to maintain cellular homeostasis under the regulation of autophagy-related genes. Cellular autophagy has a dual regulatory effect on the tumor microenvironment， which always affects the occurrence and development of digestive system tumors. Therefore， the effect and mechanism of action of cellular autophagy on digestive system tumors have become a hot topic in tumor therapy in recent years. Meanwhile， the remarkable research results of targeted autophagy drugs indicate that cellular autophagy may become an important target for anti-digestive system tumors. Traditional Chinese medicine （TCM） has been widely used in the comprehensive treatment of digestive system tumors with good efficacy. A variety of active ingredients in TCM， such as flavonoids， glycosides， terpenoids， quinones， and alkaloids， can increase the expression of autophagy-associated proteins microtubule-associated protein 1 light chain 3 （LC3）Ⅱ/Ⅰ， autophagy-related gene （ATG）5， ATG7， inhibit the expression of autophagy-related protein p62 ， and induce autophagy in digestive system tumor cells， thereby exerting the anti-digestive system tumor effect. By summarizing the research results in recent years on the modulation of cell autophagy by active ingredients in TCM to fight against digestive system tumors， this paper analyzed the relevant signaling pathways， regulatory factors， and functional characteristics of cell autophagy modulation， so as to elucidate the mechanism by which active ingredients of TCM induce autophagy and to provide ideas and references for clinical application.

Breast cancer （BC）， a common malignant tumor in women， is characterized by high incidence and mortality rates， posing a serious threat to women's life and health. Currently， the commonly used treatments for BC include surgery， radiotherapy， chemotherapy， molecular targeted therapy， and endocrine therapy. Although radiotherapy and chemotherapy can effectively kill tumor cells and inhibit the proliferation and differentiation of tumor cells， they can induce adverse reactions such as hematopoietic dysfunction and impaired immune function. The other treatment methods also have problems such as drug resistance， high recurrence rates， reduced quality of life， and poor clinical efficacy. Therefore， it is urgent to explore new drugs with better efficacy and lower toxicity. Ferroptosis is a form of iron-dependent， non-apoptotic programmed cell death triggered by lipid peroxidation. In recent years， ferroptosis has become a hot topic in the field of cancer treatment and has been gradually proven to effectively inhibit the proliferation and metastasis of BC cells， reduce the drug resistance of BC to chemotherapy drugs， and enhance the sensitivity of BC to radiotherapy. Traditional Chinese medicine （TCM）， with multiple components， multiple targets， and mild side effects， is widely used in the treatment of BC. A large number of studies have shown that active ingredients of TCM， such as saponins， flavonoids， terpenoids， phenols， and polysaccharides， can inhibit the proliferation and metastasis of BC cells by modulating ferroptosis-related pathways. These include iron metabolism， lipid metabolism， cystine/glutamate antiporter system Xc^-/glutathione/glutathione peroxidase 4， Specifically， these ingredients elevate the levels of lipid peroxidation， reactive oxygen species， malondialdehyde， and Fe²⁺ in BC cells， thereby inducing ferroptosis-mediated suppression of tumor progression. This article reviews the relevant literature at home and abroad in recent years， summarizes the mechanisms of ferroptosis in regulating BC and the research progress in the active components of TCM targeting ferroptosis in the intervention of BC， aiming to provide ideas for the development of new drugs for the treatment of BC.

Objective:To explore the predictive value of changes in prealbumin for the prognosis of patients with hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF) after artificial liver treatment.Methods:From January 1, 2018 to December 31, 2021, the clinical data (including prealbumin, platelet count, lymphocyte count, alanine transaminase (ALT), etc.) of 87 patients with HBV-ACLF who received artificial liver treatment at the Department of Gastroenterology of the General Hospital of Western Theater Command PLA were retrospectively collected. The 90-day survival status of all the patients was followed up, and the patients were divided into the survival group and the mortality group according to the survival status. The clinical characteristics and the changes of prealbumin on day 1 to 3, day 3 to 7, and day 1 to 7 after artificial liver treatment were compared between the 2 groups. Multivariate logistic regression analysis was used to analyze the independent influencing factors of the 90-day prognosis of HBV-ACLF patients after artificial liver treatment, and the nomogram prediction model was established and the receiver operating characteristic curve (ROC) was drawn to assess the area under the curve (AUC). Hosmer-Lemeshow goodness-of-fit test, calibration curve and clinical decision curve were performed to evaluate the goodness of fit, consistency and clinical value of the prediction model. Paired t-test and Mann-Whitney U test were used for statistical analysis. Results:There were 69 cases enrolled into the survival group, and 18 cases enrolled into the mortality group. The levels of albumin, prealbumin, platelet count, lymphocyte count, and ALT before treatment, and the level of prealbumin at the 3rd day after treatment of the survival group were all higher than those of the mortality group (32.5 (30.6, 35.2) g/L vs. 29.4 (27.6, 32.3) g/L, 66.0 (52.5, 81.5) mg/L vs. 56.5 (39.2, 65.0) mg/L, 103.0 (72.5, 145.0)×10 9/L vs. 63.5 (40.0, 92.5)×10 9/L, 1.1 (0.8, 1.4)×10 9/L vs. 0.9 (0.5, 1.1)×10 9/L, (514.7±86.4) U/L vs. (328.2±93.4) U/L, 90.0 (69.5, 102.5) mg/L vs.68.5(60.0, 75.8) mg/L), and the age, the level of total bilirubin, international normalized ratio, and prothrombin time before treatment of the survival group were all lower than those of the mortality group (48.0 (42.0, 57.0) years old vs. 48.5 (47.0, 56.0) years old, 323.9 (261.2, 409.2) μmol/L vs. 452.2 (405.8, 510.8) μmol/L, 1.5 (1.3, 1.9) vs. 1.9 (1.4, 2.1), 17.3 (14.6, 20.8) s vs. 21.4 (16.6, 23.2) s), and the differences were statistically significant ( Z=-3.38, -2.87, -2.38 and -2.01, t=2.39, Z=-4.11, 3.00, 3.64, 2.18 and 2.37; all P<0.05). The change of prealbumin on day 1 to 3 after treatment in the mortality group was greater than that in the survival group (-0.182 (-0.321, -0.026) vs. -0.043 (-0.133, 0.093)), and the difference was statistically significant ( Z=-3.42, P=0.001). The results of multivariate logistic regression analysis showed that the age, total bilirubin before treatment, and the change of prealbumin on day 1 to 3 after treatment were independent influencing factors for the 90-day prognosis in HBV-ACLF patients after artificial liver treatment (all P<0.05), and the nomogram model was established based on the above 3 factors. The results of ROC analysis showed that the AUC of the prediction model was 0.933 (95% confidence interval: 0.866 to 1.000, P<0.001), with a sensitivity of 0.933 and a specificity of 0.825. The results of the Hosmer-Lemeshow goodness-of-fit test showed that the prediction model had a good fit( P=0.700). The results of calibration curve analysis indicated that the actual curve of the prediction model was close to the calibration curve, with an average absolute error of 0.034, the consistency between the predicted probability and the actual probability was good. The clinical decision curve analysis suggested that the prediction model had significant clinical benefits. Conclusions:The changes of prealbumin after artificial liver treatment in HBV-ACLF patients can reflect the recovery of liver function. The nomogram prediction model based on the change of prealbumin on day 1 to 3 after treatment, age, and total bilirubin before treatment can better predict the 90-day prognosis of HBV-ACLF patients after artificial liver treatment.

Objective:To evaluate the clinical efficacy of transoral robotic surgery (TORS) in the treatment of malignant tongue base tumors.Methods:A multicenter study was conducted to collect and analyze the clinical data of patients with malignant tongue base tumors who underwent TORS at five otolaryngology-head and neck surgery centers in China, including Eye Ear Nose and Throat Hospital of Fudan University, Sun Yat-sen University Cancer Center, Tongji Hospital of Huazhong University of Science and Technology, Sun Yat-sen Memorial Hospital of Sun Yat-sen University, and the First Affiliated Hospital of China Medical University between January 2017 and January 2023. Among the patients, 38 were males and 11 were females, with a mean age of 59.0±8.8 years. Baseline characteristics, complications, and follow-up data were compared between groups. Independent sample t-tests or Mann-Whitney U tests was used for comparisons of continuous variables; chi-square tests or Fisher′s exact tests was applied for categorical variables. Survival analysis was performed using the Kaplan-Meier method to calculate overall survival and disease-free survival, and differences between groups were compared using the log-rank test. Results:Among the 49 patients, 41 (83.7%) were diagnosed with squamous cell carcinoma (SCC), with a p16 positive rate of 51.2% (21/41). There were no statistically significant differences between the p16-positive group ( n=21) and the p16-negative group ( n=20) in age, sex, or postoperative bleeding (all P>0.05). However, there was a significant difference in TNM stage between the two groups ( χ2=14.556, P=0.020), with the p16-positive group predominantly in stage I (66.7%) and the p16-negative group primarily in stages Ⅲ and Ⅳ (40.0% and 30.0%, respectively). The postoperative tracheotomy rate was 30.6% (15/49), and the incidence of postoperative bleeding was 6.1% (3/49). The 1-year and 3-year overall survival rates were 98.0% and 92.5%, respectively, while, the 1-year and 3-year disease-free survival rates were 89.2% and 84.9%, respectively. No significant differences were observed between the p16-positive and p16-negative groups in 3-year overall survival (100% vs. 83.8%, χ2=1.093, P=0.518) or 3-year disease-free survival (68.2% vs. 88.9%, χ2=2.161, P=0.382). Conclusion:TORS for malignant tongue base tumors demonstrates high clinical safety and favorable oncological outcomes.

The follow-up period ranged from 1 to 81 months, with an average of 24.8 months, in which, five patients(17.9%) died, five patients(17.9%) experienced local recurrence and four patients(14.3%) had distant metastases. The three year overall survival, local control rate and disease-free survival were 77.1%, 74.6% and 57.1%, respectively.Conclusion:In properly selected cases of hypopharyngeal cancer, TORS can offer acceptable survival and local control rates, which can be considered as a new useful option for the surgery of hypopharyngeal cancer.

Objective:To investigate the efficacy and feasibility of transoral robotic surgery (TORS) for resection of tumors in the parapharyngeal spaces.Methods:The clinical data of 57 patients who underwent TORS for parapharyngeal space tumors from September 2018 to February 2024 were retrospectively analyzed. These patients were treated at five medical institutions: The First Affiliated Hospital of China Medical University, Eye & ENT Hospital of Fudan University, Sun Yat-sen Memorial Hospital, Sun Yat-sen University, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, and Sun Yat-sen University Cancer Center. The patients were 28 males and 29 females, aged 17-77 years (median age, 47 years). The pathological types, locations, and sizes of the tumors, operation time, intraoperative bleeding volumes, postoperative hospital stays, and postoperative complications were evaluated. The data were analyzed using SPSS 27.0 software.Results:Postoperative pathological examination revealed 11 types of benign tumors. Among 57 cases, 27 cases had their tumors in the prestyloid spaces, predominantly with pleomorphic adenoma ( n=17), and 30 cases in the retrostyloid spaces, predominantly with schwannoma ( n=22). The tumor volumes ranged from 0.6 to 130.1 cm3, the intraoperative bleeding volumes ranged from 5 to 1 000 ml, the operation time ranged from 20 to 390 min, and the postoperative hospital stays ranged from 2 to 25 days. The total costs for individual cases were 36 000-100 000 yuan, with the highest cost in the case suffering from cerebrovascular accident. Four patients(7.0%) had tracheotomy and 36(63.2%) had nasogastric tube placement. Among the 57 patients, 5 had postoperative cavity effusion, 2 had wound dehiscence, 2 had cerebrovascular accidents, 1 had Horner syndrome, and 2 had other complications. The patients were followed up for 1-67 months, with only 1 patient with intracranial and extracranial communication relapsed. Conclusion:TORS is a safe and feasible approach for treating parapharyngeal space tumors, offering advantages such as minimal invasiveness, reduced blood loss, and faster recovery. It is suitable for parapharyngeal space tumors of various pathological types and locations. The postoperative complications are manageable, with favorable long-term follow-up results and low recurrence rates.
