Advances in the endoscopic management of gastric varices.

This review provides an overview of the treatment options available for gastric varices (GV) with a focus on endoscopic methods. Various minimally invasive techniques, including endoscopic band ligation, endoscopic cyanoacrylate injection, and transjugular intrahepatic portosystemic shunt, can be applied to the treatment of GV. Endoscopic cyanoacrylate injection is now recognized as a first-line treatment for GV.

N-3 polyunsaturated fatty acids protect esophageal epithelial cells from acid exposure.

Our previous study showed that n-3 PUFAs inhibited inflammation in rats with esophagitis. This study aimed to observe the protective effect of n-3 PUFAs against acid damage to esophageal epithelial cells (Het-1A cells) and to explore its mechanism. The level of malondialdehyde (MDA) was increased by acid exposure, while that of superoxide dismutase (SOD) was decreased.

Effect of Endoscopic Appendix Intubation and Irrigation on Acute Uncomplicated Appendicitis.

Objective: To investigate the efficacy and safety of endoscopic appendix intubation and irrigation (EAI) on acute uncomplicated appendicitis.

Methods: This prospective non-randomized study examined 169 patients with suspected acute uncomplicated appendicitis at The First Affiliated Hospital of Fujian Medical University from October 2015 to 2017. Patients were divided into three groups: endoscopic appendix intubation and irrigation (EAI, n = 18), laparoscopic appendectomy (LA, n = 87), and antibiotic alone (A, n = 64).

Endoscopic thermocoagulation hemostasis for acute non-varicose upper gastrointestinal hemorrhage: a randomized controlled study.

Objective: This study evaluated the application of the bipolar electrocoagulation catheter via a peripheral-to-central (3 + 1) technique, relative to directly pressing only at the center of the bleeding site (direct-stroke), to effect endoscopic hemostasis of acute non-varicose gastrointestinal bleeding (ANVUGIB).

Methods: Patients (n = 148) with endoscopically diagnosed ANVUGIB were randomly apportioned to receive treatment by 3 + 1 (n = 78) or direct-stroke (n = 70) application of the bipolar electrocoagulation catheter. The 3 + 1 strategy required pressing at3 narrowly restricted sites equidistant peripheral and center to the site of bleeding.

Methods: One hundred six patients diagnosed with PPU were treated with either OTSC (n = 26) or conservative treatments (n = 80), respectively. The outcome assessments included technical success rate, clinical success rate, post-treatment complications after 1 month, mortality rate, time to resume oral feeding, length of hospital stay, and the administration of antibiotics.

Simvastatin, but not pravastatin, inhibits the proliferation of esophageal adenocarcinoma and squamous cell carcinoma cells: a cell-molecular study.

Background And Objective: Long-term statin therapy has been shown to protect against several cancers, including esophageal cancer (EC). While the mechanisms underlying this effect are not clear. We investigated the effect of hydrophobic simvastatin and hydrophilic pravastatin on the proliferation of EC cells and sought to explore the underlying mechanisms.

Balloon-assisted ultrasonic localization: a novel technique for direct percutaneous endoscopic jejunostomy.

Direct percutaneous endoscopic jejunostomy (DPEJ) is a useful method for the establishment of enteral nutrition (EN) pathway. However, the identification of stomal puncture points for DPEJ is difficult. Here we present a case treated with an improved technique for DPEJ puncture-point localization, which was named DPEJ with balloon-assisted ultrasonic localization (DPEJ-BAUL).

CALCB splice region pathogenic variants leading to plasma cell neurotropic enrichment in type 1 autoimmune pancreatitis.

Recently, we have demonstrated that PRSS1 mutations cause ectopic trypsinogen activation and thereby result in type 1 autoimmune pancreatitis (AIP). However, the molecules involved in inducing obliterative vasculitis and perineural inflammation in the pancreas are not well-described. The present study applied whole-exome sequencing (WES) to determine the underlying etiology and revealed novel missense splice region variants, CALCB c.

Effects of Different Ratio of n-6/n-3 Polyunsaturated Fatty Acids on the PI3K/Akt Pathway in Rats with Reflux Esophagitis.

BACKGROUND We designed this study to investigate the influence of different ratios of n-6/n-3 polyunsaturated fatty acid in the diet of reflux esophagitis (RE) rats' and the effect on the PI3K/Akt pathway. MATERIAL AND METHODS RE rats were randomly divided into a sham group and modeling groups of different concentrations of n-6/n-3 polyunsaturated fatty acid (PUFA): 12:1 group, 10:1 group, 5:1 group, and 1:1 group. RT-PCR and Western-blot were used to detect the expression of PI3K, Akt, p-Akt, NF-κBp50, and NF-κBp65 proteins in esophageal tissue.

Antibodies to Type IV Collagen Induce Type 1 Autoimmune Pancreatitis.

Type 1 autoimmune pancreatitis (AIP) is prototypic autoantibody-mediated diseases. Sclerosis accompanied by fiber deposition is generally regarded as the primary lesion in the development of obliterative vasculitis. However, why collagens or their antibodies play a crucial role in the pathogenesis of AIP has not been demonstrated.

The 5-HT4 receptor agonist mosapride attenuates inflammation of reflux esophagitis.

Background/aims: Chronic inflammatory processes and gastric contents related esophageal mucosal injury are two major characteristics of reflux esophagitis RE). This study was aimed to establish a rat model fitting RE major characteristics and to investigate the effects of mosapride, one of the 5-hydroxy tryptamine (5-HT)4 receptor agonists, on mucosal inflammation in RE.

Methodology: Rat RE model was established by pyloric clip and section ligation-induced chronic acid reflux esophagitis.

Multiple gene mutations in patients with type 2 autoimmune pancreatitis and its clinical features.

Background: It is now clear that there are two histological types (type 1 and type 2) of autoimmune pancreatitis (AI P). The histological substance of type 1 AI P is known as lymphoplasmacytic sclerosing pancreatitis (LPSP) or traditional AIP, and type 2 AIP is characterized by distinct histology called idiopathic duct centric pancreatitis (IDCP). Serum IgG4 increase is considered as a marker for type 1 AI P.

PRSS1 intron mutations in patients with pancreatic cancer and chronic pancreatitis.

Genetic risk factors of chronic pancreatitis (CP) have been identified and a number of studies have found that CP can lead to pancreatic cancer. Therefore, the detection of pancreatitis-associated gene mutations can aid the pancreatic cancer diagnostic process. Mutations in three genes, the cationic trypsinogen (PRSS1) gene, the cystic fibrosis transmembrane conductance regulator (CFTR) gene and the pancreatic secretory trypsin inhibitor (SPINK1) gene, have been identified as risk factors for CP.

Novel mutations of PRSS1 gene in patients with pancreatic cancer among Han population.

Background: A high mortality rate of pancreatic cancer becomes a bottleneck for further treatment with long-term efficacy. It is urgent to find a new mean to predict the early onset of pancreatic cancer accurately. The authors hypothesized that genetic variants of cationic trypsinogen (PRSS1) gene could affect trypsin expression/function and result in abnormal activation of protease activated receptor-2 (PAR-2), then lead to pancreatic cancer.
