       Objective To evaluate the predictive value of inflammatory，immune，and nutritional indicators for peritoneal metastasis after radical gastrectomy in gastric cancer and to establish a predictive model applicable for preoperative risk assessment．Methods Clinical data from 85 patients with advanced gastric cancer treated at Suzhou Municipal Hospital between 2022 and 2024 were retrospectively collected．Patients were divided into two groups based on postoperative peritoneal metastasis occurrence：a metastasis group（n=44）and a non-metastasis group（n=41）．Indicators analyzed and compared between groups included nutritional parameters（serum albumin，fibrinogen，PNI），inflammatory markers（neutrophil count，CRP，NLR，SII），tumor markers and immune indicators（lymphocyte count，IL-2，IL-6，TNF-α，IFN-γ）．Univariate and multivariate logistic regression analyses identified independent predictors for constructing the prediction model．Internal validation was performed using 1 000 bootstrap resamples to calculate the adjusted area under the curve（AUC）and shrinkage factor for model optimization．Results Multivariate analysis identified IL-6（OR=1.116，95%CI：1.020-1.224）and CA125（OR=1.016，95%CI：1.006-1.026） as independent predictors of postoperative peritoneal metastasis．The constructed predictive model demonstrated good discriminatory ability，with an initial AUC of 0.801（95%CI：0.702–0.900）and a bootstrap-corrected AUC of 0.797．The model exhibited ideal calibration and good clinical robustness．Conclusions This study established a predictive model based on preoperative IL-6 and CA125 levels to assess the risk of peritoneal metastasis after radical surgery in gastric cancer patients．The model effectively identifies high-risk cases preoperatively，providing critical guidance for developing individualized adjuvant treatment and follow-up strategies，with potential to improve patient prognosis．

Objective To investigate the expression of MAML1 and its relationship with clinical characteristics, prognosis and the efficiency of immunotherapy in patients with GC. Methods MAML1 expression profile was observed by TCGA database. Kaplan-Meier survival analysis was applied to evaluate the correlation between the expression of MAML1 and clinical characteristics, prognosis and treatment efficiency of patients in GSE15459 dataset. MAML1-associated genes were predicted by STRING and were enriched in GO and KEGG by FUNRICH software. The relationship between MAML1 expression and markers of tumor infiltrated cells were explored by TIMER and GEPIA database. Results MAML1 was abnormally upregulated in GC tissues compared to normal gastric tissues (P<0.001). MAML1 expression was significantly associated with the overall survival of patients in stage III, with lymph node metastasis and without distant metastasis (P<0.001). There was no significant difference between MAML1 expression and the overall survival of patients in stage I, II, IV, without lymph node metastasis and with distant metastasis (P>0.05). MAML1-assoicated genes were mainly located at the nucleus, mediating transcriptional regulation and mainly enriching in androgen receptor, C-MYB transcription factor and HIF-2α transcription regulation and other related signaling pathways. MAML1 expression was positively related with the expression of B cell, CD4⁺ T cell and macrophages (P<0.05), but without significant difference with tumor purity, CD8⁺ T cell, neutrophils and dendritic cells (P>0.05). Conclusions MAML1 could be used as a marker of clinical prognosis of patients with GC. The potential molecular mechanism might be associated with its function in transcriptional regulation and changes in tumor microenvironment.

Objective In this study, GEPIA database, including TCGA database and GTEx database, were used to explore the potential targets of dihydrotanshinone I on gastric cancer through oxidative stress. Methods Literatures on potential targets of dihydrotanshinone I in gastric cancer were searched in the database;GEPIA database tool was used to analyze the potential mechanism of dihydrotanshinone I on gastric cancer;taking analysis of the correlation between potential target genes and genes expressing key antioxidant stress proteins;We had analysis of expression level of dihydrotanshinone I on potential target genes in gastric cancer patients;and prognostic analysis of dihydrotanshinone I on potential target genes in gastric cancer patients. Results The main targeting genes(proteins) of dihydrotanshinone I on potential target genes were hypoxia inducible factor-1(hif-1) and citrulline histone H3(CITH3), whose genes were HIF1 A and NOS2, respectively;GEPIA database showed that there was a positive correlation between HIF1 A and CAT(P=2e-04, R=0.18), GPX1(P=0.033, R=0.11), or NFE2L2(P=0, R=0.41), while NOS2 only had a positive correlation with SOD1(P=0.21, R=0.18), and no correlation with other three genes. The expression levels of HIF1 A and NOS2 in gastric cancer tissues were higher than those in normal adjacent gastric tissues. The overall survival rate of patients with gastric cancer decreased with the high expression of HIF1 A. Conclusion Dihydrotanshinone I may induce apoptosis of AGS cells through reactive oxygen species mediated oxidative stress, and inhibit the expression of HIF1 A and NOS2, thus inhibit their antioxidative stress, which may improve the overall survival rate of gastric cancer patients.

Objective To evaluate the anticancer actions of dihydrotanshinone Ⅰ(DHTS)in gastric cancer cells. Methods Cell viability was determined using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)assay. Intracellular reactive oxygen species (ROS)levels were determined using flow cytometry. Caspase activities were measured with fluorometric assay. The anticancer activity of DHTS in nude mouse gastric cancer model was verified. Results MTT assay showed that DHTS greatly inhibited HCG27 or AGS cell viability in dose- and time-dependent manners. Elevated intracellular ROS levels and increased apoptotic cells were observed in DHTS-treated HCG27 or AGS cells. In addition, activation of caspase-3 and caspase-8, rather than caspase-9, were noticed in DHTS-treated HCG27 or AGS cells. Furthermore, blocking ROS generation with N-acetylcysteine markedly reversed DHTS-induced cell apoptosis. DHTS inhibited the increase of tumor volume in mice. Conclusion All the findings strongly suggest that DHTS may initiate ROS generation and induce oxidative stress and cell apoptosis in HCG27 or AGS human gastric cancer cells, which deserves to be further developed as an anticancer agent.
