Impacts of Inflammatory Cytokines Variants on Systemic Inflammatory Profile and COVID-19 Severity.

Background: Cytokine storm is known to impact the prognosis of coronavirus disease 2019 (COVID-19), since pro-inflammatory cytokine variants are associated with cytokine storm. It is tempting to speculate that pro-inflammatory cytokines variants may impact COVID-19 outcomes by modulating cytokine storm. Here, we verified this hypothesis via a comprehensive analysis.

The gut microbiota participates in the effect of linaclotide in patients with irritable bowel syndrome with constipation (IBS-C): a multicenter, prospective, pre-post study.

Background: Interindividual variation characterizes the relief experienced by constipation-predominant irritable bowel syndrome (IBS-C) patients following linaclotide treatment. Complex bidirectional interactions occur between the gut microbiota and various clinical drugs. To date, no established evidence has elucidated the interactions between the gut microbiota and linaclotide.

Case report: An unusual case of small bowel bleeding and common iliac artery pseudoaneurysm caused by an unnoticed swallowed toothpick.

Gastrointestinal (GI) bleeding is a common clinical condition that can be caused by a variety of reasons. Bleeding can occur anywhere in the GI tract, and it usually presents as vomiting of blood, melena or black stools. We herein present a case of a 48-year-old man who was ultimately diagnosed with perforation of the lower ileum, pseudoaneurysm of the right common iliac artery, lower ileum-right common iliac artery fistula, and pelvic abscess caused by accidental ingestion of a toothpick.

Acute myocardial infarction followed by radiofrequency therapy for gastroesophageal reflux disease in a man: A case report.

Coronary artery disease (CAD) is a common comorbidity of gastroesophageal reflux disease. Since the distal esophagus and heart share a common afferent vagal supply, the delivery of radiofrequency in the distal esophagus can stimulate the coronary artery and induce acute myocardial infarction in a patient with CAD.

Minimally invasive treatment of cirrhotic secondary hypersplenism with high-intensity focused ultrasound.

High-intensity focused ultrasound (HIFU) has been reported to be a minimally invasive effective method for the treatment of secondary hypersplenism. However, neither the short-term efficacy nor the indications and/or contraindications have been described in patients with cirrhosis. From October 2019 to May 2021, eleven cases of patients with cirrhotic secondary hypersplenism were enrolled.

The prevalence of coronary atherosclerosis in patients with refractory gastroesophageal reflux disease ready for antireflux surgery.

Coronary atherosclerosis (CAS) and gastroesophageal reflux disease (GERD) share common risk factors. The existing CAS may not only increase the possibility of GERD to be refractory GERD (RGERD), but also increase the risk of antireflux surgery for these patients. The aim of this study was to estimate the prevalence of CAS and its potential risk factors in patients with RGERD ready for antireflux surgery.

Cap-assisted endoscopic sclerotherapy is effective for rectal mucosal prolapse associated outlet obstructive constipation.

Background And Study Aims: Outlet obstructive constipation (OOC) is a common type of chronic constipation that is usually caused by internal hemorrhoids (IH) and rectal mucosal prolapse (RMP). Cap-assisted endoscopic sclerotherapy (CAES) was demonstrated to be effective in the treatment of IH and RMP. This study explored the efficacy of CAES in treating OOC associated with IH and RMP.

Gastroesophageal reflux disease and salivary pepsin in patients with heterotopic gastric mucosa in the upper esophagus.

Background: Heterotopic gastric mucosa in the upper esophagus (HGMUE) is reported to be related to gastroesophageal reflux disease (GERD). This study investigated the prevalence of GERD and the use of salivary pepsin to diagnose gastroesophageal reflux, especially proximal reflux, in HGMUE patients.

Methods: One hundred and fifty-three HGMUE patients and 50 healthy volunteers were studied.

Chloride intracellular channels as novel biomarkers for digestive system tumors (Review).

Digestive system malignant tumors are common tumors, and the traditional treatment methods for these tumors include surgical resection, radiotherapy, chemotherapy, and molecularly targeted drugs. However, diagnosis remains challenging, and the early detection of postoperative recurrence is complicated. Therefore, it is necessary to explore novel biomarkers to facilitate clinical diagnosis and treatment.

Roles of Cl/HCO anion exchanger 2 in the physiology and pathophysiology of the digestive system (Review).

Cl/HCO anion exchangers (AEs), which are members of the solute carrier 4 family, contribute to the exchange of one intracellular HCO for one extracellular Cl. AE2, a vital subtype of the Cl/HCO exchangers, is expressed widely in various cells and tissues in mammals and serves essential roles in the pathophysiological processes of the cardiovascular system and renal tubular reabsorption. Recently, research on the function of AE2 in the digestive system shed new light on its roles in the regulation of cellular and organ physiology.

Transient delayed gastric emptying following laparoscopic Nissen fundoplication for gastroesophageal reflux disease.

Purpose: Although laparoscopic Nissen fundoplication (LNF) is a kind of minimally invasive surgery, some transition time may still be required to allow the fundoplicated stomach to adapt to the new anatomical position. We observed transient delayed gastric emptying (DGE) post-LNF in our preliminary study. This study aimed to investigate the occurrence rate and development of transient DGE post-LNF.

A case report of eosinophilic gastroenteritis misdiagnosed as cholelithiasis.

Eosinophilic gastroenteritis is not only easy to ignore in clinical practice, but also easy to miss in the process of pathological diagnosis. There is a need to consider it in the differential diagnosis of alimentary disease.

Cap-assisted endoscopic sclerotherapy for internal hemorrhoids: technique protocol and study design for a multi-center randomized controlled trial.

Background: Cap-assisted endoscopic sclerotherapy is a new interventional therapy for internal hemorrhoids and rectal prolapse under colonoscopy. The proper length of the endoscopic injection needle is the core for performing cap-assisted endoscopic sclerotherapy well with more benefits and less complications. However, no data are currently available to guide endoscopists to consider the length of injection needle before cap-assisted endoscopic sclerotherapy.

Effect of VIATORR stent in early ultrasound evaluation after transjugular intrahepatic portosystemic shunt (TIPS): A case report.

Shunt dysfunction is a major complication of transjugular intrahepatic portosystemic shunt (TIPS). Ultrasonography is a preferred method of shunt follow-up after TIPS, but some misjudgments can occur in cases of shunt dysfunction due to peculiarities of the VIATORR stent. Here we report one case and suggest that the first ultrasound evaluation for patients who received TIPS procedure with VIATORR stent should be performed one month after the procedure.

To compare the Stretta procedure with proton pump inhibitors for the treatment of nonerosive reflux disease (NERD).From July 2018 to April 2019, patients diagnosed with NERD and referred for treatment were enrolled. They were treated with either Stretta procedure or proton pump inhibitor (PPI) medication and followed-up for 6 months.

24-hour monitoring of transient lower esophageal sphincter relaxation events by long-term high-resolution impedance manometry in normal volunteers: The "mirror phenomenon".

Background: The aim of this study was to investigate the frequency and circadian changes in transient lower esophageal sphincter relaxations (TLESRs) in normal volunteers using 24-hour high-resolution impedance manometry (HRIM).

Methods: Fifteen volunteers underwent HRIM. TLESRs were recorded during the mealtime, 2-hour postprandial, daytime, and supine periods.

Prevalence and Predictors of Silent Gastroesophageal Reflux Disease in Patients with Hypertension.

Background: Gastroesophageal reflux disease (GERD) without symptoms or silent GERD can be easily missed in patients with hypertension. We aimed to investigate the prevalence of GERD, specifically the prevalence of silent GERD in hypertensive patients, and to explore its possible predictors.

Methods: Consecutive patients with hypertension referred to the cardiovascular clinic of Suining Central Hospital in 2016 were screened for this study.

Visfatin increases miR-21 to promote migration in HCC.

Hepatocellular carcinoma (HCC) is a common human malignancy. In this study, we aimed to investigate the serum levels of visfatin and miR-21 in HCC patients, to analysis the relationship between the pathological features and the plasma level of visfatin or miR-21, and to explore the roles of visfatin and miR-21 in migration of HCC cells. Our results showed that the serum levels of visfatin and miR-21 were significant higher in HCC patients than healthy subjects.

Endoluminal Sphincter Augmentation with the MUSE™ System and GERDX™ System in the Treatment of Gastroesophageal Reflux Disease: A New Impact?

To bridge the gap between the long-term intake of proton pump inhibitors (PPIs) and the potential risks of laparoscopic fundoplication, a number of endoscopic procedures for the treatment of gastro-esophageal reflux disease (GERD) have been developed over the past 30 years. Because of the minimally invasive approach, short operative time, and efficacy in selected patients, endoluminal sphincter augmentation appears to be highly attractive. However, most early devices have proven to be unsafe or failed to provide long-term symptom relief.

Graphene oxide directed in-situ deposition of electroactive silver nanoparticles and its electrochemical sensing application for DNA analysis.

The development of high-performance biosensing platform is heavily dependent on the recognition property of the sensing layer and the output intensity of the signal probe. Herein, we present a simple and highly sensitive biosensing interface for DNA detection on the basis of graphene oxide nanosheets (GONs) directed in-situ deposition of silver nanoparticles (AgNPs). The fabrication process and electrochemical properties of the biosensing interface were probed by electrochemical techniques and scanning electron microscopy.

Label-free electrochemical lead (II) aptasensor using thionine as the signaling molecule and graphene as signal-enhancing platform.

A label-free and highly sensitive electrochemical aptasensor for Pb(2+) was constructed using thionine (TH) as the signaling molecule and graphene (GR) as the signal-enhancing platform. The electrochemical sensing interface was fabricated by stepwise assembly of GR and TH on the lead (II) specific aptamer (LSA) modified electrode. Upon interaction with Pb(2+), the aptamer probe on the sensor underwent conformational switch from a single-stranded DNA form to the G-quadruplex structure, causing the GR with assembled TH released from the electrode surface into solution.

β-Cyclodextrin functionalized graphene as a highly conductive and multi-site platform for DNA immobilization and ultrasensitive sensing detection.

A versatile nanocomposite containing β-cyclodextrin and graphene (CD-GR) was prepared through a simple chemical reduction method. The characterization experiments show that the nanocomposite remains the flake-like morphology of GR, but its solubility and stability in aqueous solution are greatly improved. Then the nanocomposite was modified at glassy carbon electrode (GCE) surface, and was used as a functional matrix for the covalent immobilization of probe DNA using 2,4,6-trichloro-1,3,5-triazine (TCT) as the crosslinker.
