Nonsteroidal Anti-inflammatory Drugs for the Prevention of Post-endoscopic Retrograde Cholangiopancreatography Pancreatitis.

Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) remains the most frequent and severe complication following ERCP, elevating both patient suffering and healthcare costs, and posing challenges to the advancement of ERCP techniques. Empirical evidence supports the prophylactic use of nonsteroidal anti-inflammatory drugs (NSAIDs) in the prevention of PEP, especially in high-risk populations, as endorsed by both the American Society for Gastrointestinal Endoscopy (ASGE) and the European Society for Gastrointestinal Endoscopy (ESGE). However, the prophylactic efficacy of NSAIDs in average-risk individuals, alongside the ideal drug selection, dosing, and timing of NSAID administration, remains to be elucidated.

Case report: a precancerous lesion associated with HPV in the anal canal diagnosed by magnifying endoscopy with narrow-band imaging and resected by endoscopic submucosal dissection.

Although anal cancer remains rarely diagnosed in the world, its frequency is rising, especially in high-risk groups. The prognosis of advanced anal cancer is poor. However, there are still few reports on the endoscopic diagnosis and treatment of early anal cancer and its precancerous lesions.

Asporin represses gastric cancer apoptosis via activating LEF1-mediated gene transcription independent of β-catenin.

Asporin (ASPN) presents in the tumor microenvironment and exhibits a cancer-promoting effect as a stroma protein. Even though ASPN has already been observed inside cancer cells, the functions of intracellular ASPN and its underlying mechanisms remain unknown. Here we reported that ASPN was upregulated in different stages of gastric cancer (GC), and associated with a poor prognosis.

Exosomal Sonic Hedgehog derived from cancer-associated fibroblasts promotes proliferation and migration of esophageal squamous cell carcinoma.

Esophageal squamous cell carcinoma (ESCC) is one of the most common and aggressive malignancies in China. Cancer-associated fibroblasts (CAFs) can actively communicate with and stimulate tumor cells, thereby contributing to the development and progression of tumors. Yet, whether CAFs-derived exosomes have a role in the progression of ESCC is largely unknown.

Identification of Gut Microbiota and Metabolites Signature in Patients With Irritable Bowel Syndrome.

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder. However, the underlying mechanism of IBS is not fully understood. The aim of this study was to investigate potential mechanism and novel biomarkers of IBS through evaluation of the metabolomic and microbiologic profile.

RBBP8/CtIP suppresses P21 expression by interacting with CtBP and BRCA1 in gastric cancer.

RB Binding Protein 8 (RBBP8) was previously reported being involved in DNA double-strand break (DSB) repair in cancers. However, there is no systematic study about the specific functions and related mechanisms of RBBP8 in gastric carcinogenesis. Through immunohistochemistry staining of paired gastric cancer (GC) tissues, adjacent high-grade intraepithelial neoplasia (HGIEN) tissues, and non-cancerous tissues, we found RBBP8 expression was upregulated in both HGIEN and GC tissues.

Cyclin-Dependent Kinase Inhibitor 3 Promoted Cell Proliferation by Driving Cell Cycle from G1 to S Phase in Esophageal Squamous Cell Carcinoma.

. Cyclin-dependent kinase inhibitor 3 (CDKN3) has been found playing a varying role in carcinogenesis, but its biological function in esophageal squamous cell carcinoma (ESCC) is unclear. The aim of this study was to demonstrate the role of CDKN3 in ESCC.

Multi-omics Analysis of Gut Microbiota and Metabolites in Rats With Irritable Bowel Syndrome.

Irritable bowel syndrome (IBS) is a common gastrointestinal dysfunctional disease. The pathophysiology of IBS is, however, largely unknown. This study aimed to determine whether evaluation of fecal metabolite and microbiota profiles may offer an opportunity to identify a novel pathophysiological target for IBS, and to reveal possible gut microbe-metabolite associations.

Asporin promotes cell proliferation via interacting with PSMD2 in gastric cancer.

Asporin (ASPN), a member of small leucine-rich repeat proteoglycan (SLRP) family of proteins, serves important roles in diverse biological responses and disease conditions. We tested the hypothesis that ASPN regulated proliferation of gastric cancer (GC) cells and identified its down-stream regulators. ASPN promoted the proliferation of GC cells.

FAM175B promotes apoptosis by inhibiting ATF4 ubiquitination in esophageal squamous cell carcinoma.

FAM175B is a reported regulator of p53 and suppresses tumorigenesis in numerous types of cancer, but very little is known about its function in esophageal squamous cell carcinomas (ESCCs), almost 70% of which exhibit mutations in p53. Here, we report that FAM175B expression is downregulated in high-grade intraepithelial neoplasia (t = 2.44, P = 0.

Cytoplasmic Asporin promotes cell migration by regulating TGF-β/Smad2/3 pathway and indicates a poor prognosis in colorectal cancer.

Previous studies revealed that Asporin (ASPN) is a potential mediator in the development of various types of cancer as a secreted stroma protein, but the function of ASPN inside the cancer cells remains largely unknown. Here, we demonstrated a higher expression level of ASPN in colorectal cancer (CRC) than matched normal tissues, and 25% (2/8) CRC showed copy number variation (CNV) gain/amplification in ASPN gene. Both higher ASPN expression levels and ASPN CNV gain/amplification indicated a worse prognosis in CRC patients.

A nomogram for endoscopic screening in a high esophageal squamous cell cancer risk area: results from a population-based study.

Background: Endoscopy is the main approach used for esophageal squamous cell carcinoma (ESCC) screening, especially in high-risk areas. However, little consensus has been achieved in recent ESCC screening programs, and endoscopists have selected patients only by age and family history.

Patients And Methods: To generate a proper strategy for selecting an eligible population for endoscopic screening based on demographic factors, lifestyle, and eating habits, a total of 7,830 residents in an area with a high risk of ESCC were recruited for this study.

Transcriptome and methylome profiling in a rat model of irritable bowel syndrome induced by stress.

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder that is associated with psychological stress. However, the full landscape of IBS‑related epigenetic factors remains unveiled and needs to be elucidated. The water‑avoidance stress (WAS) method was used to induce a rat IBS model.

Gene regulatory network construction identified NFYA as a diffuse subtype-specific prognostic factor in gastric cancer.

Lauren classification is a pathology-based gastric cancer (GC) subtyping system, which is widely used in the clinical treatment of patients with GC. However, genome-scale molecular characteristics to distinguish between diffuse (DF) and intestinal (IT) GC remain incompletely characterized, particularly at the transcriptional regulatory level. In the present study, gene regulatory networks were constructed using the Passing Attributes between Networks for Data Assimilation (PANDA) algorithm for DF, IT and mixed GC.

Cadherin Expression Shift Could Well Distinguish Esophageal Squamous Cell Carcinoma from Non- Cancerous Esophageal Tissues.

Background: Biomarkers for esophageal squamous cell carcinoma (ESCC) identification with high sensitivity are not well established. Since abnormal expression of cadherins has been widely reported in cancer, we explored its feasibility as an ESCC biomarker.

Methods: Expression of E-cadherin and N-cadherin were detected in 150 esophageal tissues by immunohistochemistry.

Factors associated with gastric adenocarcinoma and dysplasia in patients with chronic gastritis: a population-based study.

Objective: Gastric cancer (GC) is one of the leading causes of death in China and other Asian countries. Recently, gastric endoscopy has become the main approach for GC screening, but the identification of high-risk individuals remains a challenge in GC screening programs.

Methods: There were 7,302 patients with chronic gastritis involved in this study.
