Comparable long-term outcomes after endoscopic therapy and gastrectomy of early adenocarcinoma of esophagogastric junction: a population-based study.

Background And Aims: Current guidelines recommend consideration of endoscopic therapy (ET) when treating selected early gastric cancers. However, clinical decision-making on ET versus gastrectomy for early adenocarcinoma of esophagogastric junction (AEGJ) remains challenging because of uncertain long-term outcomes.

Methods: We performed a retrospective cohort study using the Surveillance, Epidemiology, and End Results database from 2004 to 2017 of early AEGJ patients underwent ET or gastrectomy.

NLRP3 inflammasome inhibition attenuates subacute neurotoxicity induced by acrylamide in vitro and in vivo.

Acrylamide (AA) constitutes an important industrial chemical agent and well-known neurotoxin. However, the mechanism underlying AA-mediated neurotoxicity is extremely complicated and controversial. In this study, we found that activation of the NLR family pyrin domain containing 3 (NLRP3) inflammasome and its subsequent downstream inflammatory responses plays an important role in AA-induced neurotoxicity mechanisms.

Influence of Tumor Location on Lymph Node Metastasis and Survival for Early Gastric Cancer: a Population-Based Study.

Background: The question that whether the criteria for endoscopic resection of early gastric non-cardia cancer (GNCC) is appropriate for early gastric cardia cancer (GCC) remains unclear. Thus, our aim was to evaluate the influence of tumor location on lymph node metastasis (LNM) and overall survival (OS) for early gastric cancer (GC).

Methods: A total of 5440 early GC patients in the Surveillance, Epidemiology, and End Results (SEER) database were identified.

Modified American Joint Committee on Cancer Tumor-Node-Metastasis Staging System Based on the Node Ratio Can Further Improve the Capacity of Prognosis Assessment for Gastric Cancer Patients.

Our aim was to investigate whether the modified American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) staging system based on the node ratio can further improve the capacity of prognosis assessment for gastric cancer (GC) patients regardless of the number of lymph nodes examined (eLNs). A total of 17,187 GC patients in the Surveillance, Epidemiology, and End Results (SEER) database were included. On the basis of a training set of 7,660 GC patients, we built the tumor-node ratio-metastasis (TNrM) staging system, which was then externally validated with a validation set of 9,527 GC patients.

Madecassoside protects BV2 microglial cells from oxygen-glucose deprivation/reperfusion-induced injury via inhibition of the toll-like receptor 4 signaling pathway.

In a previous study, the authors reported that madecassoside (MA) exerted a potent neuroprotective effect against cerebral ischemia-reperfusion (I/R) injury in rats, mediated by anti-oxidative, anti-inflammatory, and anti-apoptotic mechanisms. However, the cellular and molecular bases for its neuroprotective effects have not been fully elucidated. In this study, an in vitro ischemic model of oxygen-glucose deprivation followed by reperfusion (OGD/R) was used to investigate the role of the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-kappa B (NF-κB) pathway in the neuroprotective and anti-inflammatory effects of MA.
