High concentrations of polyethylene microplastics restrain the growth of Cinnamomum camphora seedling by reducing soil water holding capacity.

The accumulation of microplastics (MPs) in soils due to anthropogenic activities affects the growth and development of plants and thereby endangering the diversity and function of ecosystems. Although there is an increasing number of studies exploring the effects of MPs on plants in recent days, most of them focus on crops only. However, few studies have been conducted on woody plants that play a prominent role in ecosystems, while crucial edaphic factors which potentially restrain plant growth in MP-contaminated soils are yet to be revealed.

A novel and challenging EUS-guided bridging technique for hilar cholangiocarcinoma (Bismuth IV) after total gastrectomy.

The incidence of hilar cholangiocarcinoma is (1-2) / 100,0001. Due to the high location of obstruction, the treatment of hilar cholangiocarcinoma is complicated, especially for patients with gastrointestinal surgery. The traditional ERCP technique is to find a way to place more stents to treat obstructive jaundice.

Screening and Predictive Biomarkers for Down Syndrome Through Amniotic Fluid Metabolomics.

Background: Down syndrome (DS) is a congenital disorder caused by the presence of an extra copy of all or part of chromosome 21. It is characterized by significant intellectual disability, distinct facial features, and growth and developmental challenges. The utilization of metabolomics to analyze specific metabolic markers in maternal amniotic fluid may provide innovative tools and screening methods for investigating the early pathophysiology of trisomy 21 at the functional level.

Swiprosin-1 participates in the berberine-regulated AMPK/MLCK pathway to attenuate colitis-induced tight junction damage.

Background And Purpose: Activation of AMP-activated protein kinase (AMPK) is essential in maintaining the epithelial tight junction (TJ) barrier. Berberine, a phytochemical AMPK agonist, has been widely reported to ameliorate colitis. Berberine or AMPK activation inhibits cytoskeletal contraction induced by myosin light chain kinase (MLCK), thereby ameliorating TJ barrier defects.

Endoscopic treatment of postoperative intestinal stenosis combined with bilioenteric anastomotic stenosis.

Postoperative anastomotic stenosis is a common complication after biliary, pancreatic and gastrointestinal surgery, which may be caused by multiple factors such as tissue proliferation and cancer recurrence. Endoscopic therapy is often hampered when the lens is difficult to pass through. A patient with intestinal stricture complicated by bilioenterostomy stenosis was treated by superselection of guide wire and stent.

Endoscopic segmentalized drainage of biliary tract obstruction complicated with duodenal stenosis.

Biliary obstruction is a common gastrointestinal disorder with many etiological factors, such as benign and malignant diseases of the biliary tract, pancreas, and liver. Endoscopic ultrasound guided biliary drainage provides a new method for the treatment of biliary obstruction when ERCP cannula fails.

Main chemical constituents and mechanism of anti-tumor action of Solanum nigrum L.

Objective: Solanum nigrum L. (SNL) is a natural drugwith diverse bioactive components and multi-targeted anti-tumor effects, gaining increasing attention in clinical application.

Method And Results: This paper reviews the studies on SNL by searching academic databases (Google Scholar, PubMed, Science Direct,and Web of Science, among others), analyzing its chemical compositions (alkaloids, saponins, polysaccharides, and polyphenols, among others), andbriefly describes the anti-tumor mechanisms of the main components.

Caffeic Acid Reduces Ferroptosis to Dampen Inflammation of Keratinocytes in Psoriasis by Inhibiting EGR1-induced Transcription Activation of CHAC1.

Background: Ferroptosis of keratinocytes is closely associated with amplification of skin inflammation in psoriasis. This study focuses on unlocking the role of caffeic acid (CA), a polyphenol compound, in keratinocyte ferroptosis and understanding the underlying mechanistic basis.

Methods: The interaction between early growth response protein 1 (EGR1) and chac glutathione specific γ‑glutamylcyclotransferase 1 (CHAC1) was predicted by bioinformatics and validated via chromatin immunoprecipitation and dual-luciferase reported assays.

Monocyte/macrophage-mediated venous thrombus resolution.

Venous thromboembolism (VTE) poses a notable risk of morbidity and mortality. The natural resolution of the venous thrombus might be a potential alternative treatment strategy for VTE. Monocytes/macrophages merge as pivotal cell types in the gradual resolution of the thrombus.

Pancreatic fistula after pancreaticoduodenectomy - Alternative therapy of endoscopic ultrasound guided pancreatic duct puncture drainage.

Pancreatic fistula is a very difficult complication after pancreatic surgery(1). Endoscopic ultrasound guided drainage of pancreatic duct (EUS-PD)was a challenging endoscopic procedure that can solve the problem of postoperative pancreatic fistula. However, EUS-PD cannot be completed in patients with undilated pancreatic ducts.

QPH-FR: A Novel Quinoa Peptide Enhances Chemosensitivity by Targeting Leucine-Rich Repeat-Containing G Protein-Coupled Receptor 5 in Colorectal Cancer.

Chemoresistance is one of the difficulties in the treatment of colorectal cancer (CRC), and the enhanced stemness of tumor cells is the underlying contributing factor. Leucine-rich repeat-containing G-protein-coupled receptor 5 (LGR5) is a classical marker of CRC stem cells and can be an important potential target for CRC chemotherapy. Quinoa, a protein-rich plant, offers potential as a source of high-quality active peptides.

ERCP-Related adverse events in pediatric patients: a 10-years single-site review.

Purpose: This retrospective analysis aimed to assess the feasibility and safety of endoscopic retrograde cholangiopancreatography (ERCP) in pediatric patients by examining ERCP-related adverse events (AEs) occurring over a decade at a single center.

Methods: Pediatric patients under 18 years old who underwent ERCP at the Second Hospital of Hebei Medical University from 1/2013 to 11/2023 were included. ERCP-related AEs were defined according to ERCP-related adverse events: European Society of Gastrointestinal Endoscopy (ESGE) Guideline.

External fistula internalization - Endoscopic ultrasound guided stent implantation between stomach and fistula in the treatment of refractory pancreatic cutaneous fistula.

Pancreatic cutaneous fistula is a complex condition, making it challenging to achieve favorable outcomes with conservative medical treatment. Surgical interventions often entail surgical risks and postoperative complications. Here, we present a case involving endoscopically guided stent placement between the stomach and the fistula.

Endoscopic management of recurrent obstructive jaundice after EUS-guided biliary drainage.

EUS-GUIDED biliary drainage (EUS-BD) has recently gained widespread acceptance as a minimally invasive alternative method for biliary drainage. However, the risks of encountering recurrent biliary obstruction (RBO) after EUS-BD have increased due to the growing clinical experience of EUS-BD and prolonged prognosis of the underlying disease. Previous studies have shown that the incidence of RBO following EUS-BD ranges from 11% to 25%.

Rheological characterization of chia seed gum as a thickening agent used for dysphagia management.

Dysphagia has emerged as a serious health issue facing contemporary society. Consuming thickened liquids is an effective approach for improving the swallowing safety for dysphagia patients. The thickening effect of chia seed gum (CSG), a novel thickener, in different dispersing media (water, orange juice, and skim milk) was investigated.

Simplified single-session EUS-guided transhepatic antegrade stone removal for management of choledocholithiasis in patients with surgically altered anatomy.

Background: Endoscopic ultrasound (EUS)-guided transhepatic antegrade stone removal (TASR) has been reserved for choledocholithiasis after failed endoscopic retrograde cholangiopancreatography (ERCP) in recent years. The aim of this study was to evaluate the techniques, feasibility, and safety of simplified single-session EUS-TASR for choledocholithiasis in patients with surgically altered anatomy (SAA).

Methods: A retrospective database of patients with SAA and choledocholithiasis from the Second Hospital of Hebei Medical University (Shijiazhuang, China) between August 2020 and February 2023 was performed.
