Objective To compare the long-term survival outcomes of patients with T1-2N0M0 duodenal neuroendocrine tumor (DNET) after endoscopic resection (ER) or surgical resection (SR). Methods Patients diagnosed with T1-2N0M0 DNET between January 1, 2004, and December 31, 2015, were extracted from the SEER database. Kaplan-Meier survival curve and log-rank test were used to compare overall survival (OS) rate and cancer-specific survival (CSS) rate between patients undergoing ER or SR. Propensity score matching (PSM) was used to reduce grouping differences, and multivariate Cox regression was used to analyze factors affecting OS and CSS before and after PSM. Results A total of 656 patients were included, with 457 in ER group and 199 in SR group. Before PSM, there was no significant difference in the 5-year OS rate between the ER and SR groups (88.9% vs 89.6%), but there was a significant difference in the 5-year CSS rate (99.3% vs 96.9%, P=0.017). Before PSM, multivariate Cox regression analysis showed advanced age was an independent risk factor for decreased OS (P<0.001). After PSM, there was no significant difference between the ER group (n=187) and SR group (n=187) in 5-year OS rate (90.2% vs 88.9%) or CSS rate (98.9% vs 96.7%). After PSM, multivariate Cox regression also showed advanced age was an independent risk factor for decreased OS, while resection method was not an independent factor for OS or CSS. Conclusions There is no significant difference in OS or CSS after endoscopic treatment and surgical treatments for patients with T1-2N0M0 DNET, and advanced age is an independent factor for OS.

OBJECTIVE:
To study the in vitro and in vivo antitumor effects of the polysaccharide of Alocasia cucullata (PAC) and the underlying mechanism.
METHODS:
B16F10 and 4T1 cells were cultured with PAC of 40 µg/mL, and PAC was withdrawn after 40 days of administration. The cell viability was detected by cell counting kit-8. The expression of Bcl-2 and Caspase-3 proteins were detected by Western blot and the expressions of ERK1/2 mRNA were detected by quantitative real-time polymerase chain reaction (qRT-PCR). A mouse melanoma model was established to study the effect of PAC during long-time administration. Mice were divided into 3 treatment groups: control group treated with saline water, positive control group (LNT group) treated with lentinan at 100 mg/(kg·d), and PAC group treated with PAC at 120 mg/(kg·d). The pathological changes of tumor tissues were observed by hematoxylin-eosin staining. The apoptosis of tumor tissues was detected by TUNEL staining. Bcl-2 and Caspase-3 protein expressions were detected by immunohistochemistry, and the expressions of ERK1/2, JNK1 and p38 mRNA were detected by qRT-PCR.
RESULTS:
In vitro, no strong inhibitory effects of PAC were found in various tumor cells after 48 or 72 h of administration. Interestingly however, after 40 days of cultivation under PAC, an inhibitory effect on B16F10 cells was found. Correspondingly, the long-time administration of PAC led to downregulation of Bcl-2 protein (P<0.05), up-regulation of Caspase-3 protein (P<0.05) and ERK1 mRNA (P<0.05) in B16F10 cells. The above results were verified by in vivo experiments. In addition, viability of B16F10 cells under long-time administration culture in vitro decreased after drug withdrawal, and similar results were also observed in 4T1 cells.
CONCLUSIONS
Long-time administration of PAC can significantly inhibit viability and promote apoptosis of tumor cells, and had obvious antitumor effect in tumor-bearing mice.

AIM: To compare the efficacy and safety of tigecycline with polymyxin B in the treatment of carbapenem resistant enterobacteriaceae (CRE) pneumonia in critically ill patients. METHODS: A retrospective analysis was performed on the clinical data of patients with CRE pneumonia who received tigecycline or polymyxin B therapy from January 1, 2018 to Jun 30, 2023 in the Intensive Care Unit (ICU). Primary outcomes included the 28-day all-cause mortality and clinical cure rate within 28days. Secondary outcomes included the ICU mortality, in-hospital mortality, the length of hospital stay and ICU stay, microbial eradication, duration of mechanical ventilation. Independent predictors affecting 28-day clinical cure rate were tested using Cox regression analyses. RESULTS: A total of 83 eligible patients were included in the final analysis after propensity score matching, 54 in the tigecycline group and 29 in the polymyxin B group. The 28-day all-cause mortality was 31.5% (17/54) in the tigecycline group and 37.9% (11/29) in the polymyxin B group, the difference was not statistically significant (P=0.554); the clinical cure rate was 63% (34/ 54) in the tigecycline group, which was significantly higher than that of the polymyxin B group of 34.5% (10/29) (P = 0.013). There were no statistical differences between the two groups in terms of secondary outcomes. Multivariate logistic regression analysis found that the use of tigecycline was an independent predictor of the 28-day clinical cure rate (HR 2.083, 95%CI 1.018-4.263, P = 0.045). However, activated partial thromboplastin time (APTT) and prothrombin time (PT) were significantly prolonged in the tigecycline group compared with the polymyxin B group (P=0.047; P=0.027), and fibrinogen (FIB) was significantly decreased (P < 0.001) after drug administration. CONCLUSION: There was no significant difference in 28-day all-cause mortality between the tigecycline and polymyxin groups; tigecycline might be associated with a higher 28-day clinical cure rate compared with polymyxin B. It should be noted that tigecycline may increase the risk of coagulation abnormalities.

Objective:To study the effects of different doses of X-ray irradiation on the immune microenvironment and cGAS-STING signaling pathway of hepatocellular carcinoma cells.Methods:C57BL/C mice were subcutaneously injected with Hepa 1-6 hepatocellular carcinoma cells in the right axilla to establish a subcutaneous tumor-forming hepatocellular carcinoma model. The mice were randomly divided into 0, 4, 8, 12 Gy irradiation groups, with 10 mice in each group. The body weights and tumor volumes were monitored. Specimens were collected 28 d after irradiation. The ELLSA and Flow Cytometry method was used to compare the macrophage-associated cytokines tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-6 (IL-6), chemokine ligand 5 (CCL5), IL-10, IL-13, transforming growth factor-β (TGF-β), IL-4 and macrophage M1, M2 phenotype ratio (M1/M2). Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) and immunoblotting assay were used to detect the expression of genes and proteins related to the cGAS-STING signaling pathway in hepatoma cells.Results:With the increase of irradiation dose, the tumor volume was significantly reduced ( F=8.42, P<0.05), the proportion of cell necrosis increased ( F=3.89, P<0.05), the content of macrophage-associated cytokines other than IL-4 increased ( F=6.32-15.50, P<0.05), and the proportion of M1 and M2 types of macrophage in the immune microenvironment of hepatocellular carcinoma tumors was elevated ( F= 5.46, 5.14, P < 0.05).The gene expression and protein expression levels of cGAS-STING signaling pathway were elevated in hepatocellular carcinoma cells (mRNA expression of cGAS and STING: F=6.35, 16.10, P<0.05; protein expression of cGAS and STING: F=71.31, 37.15, P<0.05). Conclusions:X-ray irradiation activates the cGAS-STING signaling pathway in hepatocellular carcinoma cells and contributes to the remodeling of the tumor immune microenvironment.
