Combining non-invasive liquid biopsy and a methylation analysis to assess surgical risk for early esophageal cancer.

Background: While the widespread use of endoscopic submucosal dissection (ESD) has significantly reduced the incidence of early esophageal cancer (ESCA), the limited ability of ESD to strip deep infiltrating esophageal lesions results in a considerable risk of intraoperative perforation. Circulating-free DNA (cfDNA) is widely used in modern tumor screening due to its non-invasive detection capabilities. A methylation analysis offers vital insights into the condition and advancement of malignancies due to its unique positioning, such as a marker of cancer.

Metabolome Profiling of Malignant Ascites Identifies Candidate Metabolic Biomarkers of Hepatocellular Carcinoma.

Background: Malignant ascites is one of the severe complications of hepatocellular carcinoma, which can be regarded as a unique tumor microenvironment of hepatocellular carcinoma. The identification of novel biomarkers in malignant ascites could be crucial to differentiate patients with hepatocellular carcinoma and cirrhotic ascites.

Objective: The study aimed to distinguish the metabolomics of malignant ascites in patients with hepatocellular carcinoma from that of non-malignant ascites (cirrhotic ascites).

MAGED4B is a Poor Prognostic Marker of Stomach Adenocarcinoma and a Potential Therapeutic Target for Stomach Adenocarcinoma Tumorigenesis.

Background: Gastric cancer is the second most common cause of cancer death worldwide with poor overall prognosis. It is important to study the molecular mechanism of stomach adenocarcinoma (STAD). MAGED4B, a member of the melanoma antigen gene (MAGE) family, is highly expressed in many tumor cells and is associated with tumor progression.

Transcriptomic and network pharmacology approaches revealed possible mechanisms underlying the 5-fluorouracil (5-FU)-sensitizing effect of Xuan-Fu-Hua decoction treatment on liver cancer cells.

Background: Xuan-Fu-Hua decoction is a traditional Chinese medicine formula widely used for the treatment of inflammation-related disease in the lung and liver. This study aimed to investigate the effect of Xuan-Fu-Hua decoction treatment on liver cancer cells and its mechanism of action.

Methods: The impact of Xuan-Fu-Hua decoction treatment on the proliferation and apoptosis of SMMC-7721 liver cancer cells with or without 5-fluorouracil (5-FU) cotreatment was determined in both and settings.

Endoscopic tightening of the cardia mucosa in gastroesophageal reflux disease: A case series of 120 patients up to 1-year follow-up.

Background And Aim: A technique of endoscopic tightening of the cardia mucosa for the treatment of gastroesophageal reflux disease (GERD) was developed and its clinical efficacy was observed.

Methods: 120 patients with GERD who underwent endoscopic tightening surgery from December 2017 to December 2019 were included in this study. GERD-Q score and constitution type of patients were evaluated preoperatively and at 1 month, 3 months, 6 months, and 1 year after surgery.

A Study on the Static Magnetic and Electromagnetic Properties of Silica-Coated Carbonyl Iron Powder after Heat Treatment for Improving Thermal Stability.

In order to study the thermal stability of coated carbonyl iron powder (CIP) and its influence on magnetic properties, carbonyl iron powder was coated with a silica layer and then annealed in an air atmosphere at elevated temperatures. Transmission electron microscopy (TEM) analysis and Fourier transform infrared spectroscopy confirmed the existence of a silicon dioxide layer with a thickness of approximately 80~100 nm. Compared with uncoated CIP, the silicon-coated CIP still maintained a higher absorption performance after annealing, and the calculated impedance matching value Z only slightly decreased.

Background And Aim: A technique of endoscopic tightening of the cardia mucosa for the treatment of gastroesophageal reflux disease (GERD) was developed and its clinical efficacy was observed.

Methods: 120 patients with GERD who underwent endoscopic tightening surgery from December 2017 to December 2019 were included in this study. GERD-Q score and constitution type of patients were evaluated preoperatively and at 1 month, 3 months, 6 months, and 1 year after surgery.

[Molecular mechanism of astragaloside Ⅳ against atherosclerosis by regulating miR-17-5p and PCSK9/VLDLR signal pathway].

This study explores the regulatory effect of astragaloside Ⅳ on miR-17-5 p and its downstream proprotein convertase subtillisin/kexin type 9(PCSK9)/very low density lipoprotein receptor(VLDLR) signal pathway, aiming at elucidating the mechanism of astragaloside Ⅳ against atherosclerosis(AS). In cell experiment, oxidized low-density lipoprotein(ox-LDL) was used for endothelial cell injury modeling with vascular smooth muscle cells(VSMCs). Then cells were classified into the model group, miR-17-5 p inhibitor group, blank serum group, and astragaloside Ⅳ-containing serum group based on the invention.

Safety of potassium-bearing citrate in patients with renal transplantation: A case report.

Rationale: Urinary lithiasis is one of severe postoperative complications in patients undergoing renal transplantation, possibly leading to anuria, urinary infection, or even acute renal failure. Potassium sodium hydrogen citrate (PSHC), a potassium-bearing citrate, is commonly prescribed to prevent stone formation.

Patient Concerns: A 25-year-old man (patient 1) and a 31-year-old man (patient 2) receiving renal transplantation for end-stage renal disease (ESRD) were enrolled in this study.

miR-340 Inhibits Proliferation and Induces Apoptosis in Gastric Cancer Cell Line SGC-7901, Possibly via the AKT Pathway.

BACKGROUND Gastric cancer is among the most common types of cancer, with high morbidity and mortality. MicroRNAs (miRNAs) play vital roles in the tumorigenesis and biology of gastric cancer. This study aimed to reveal the role of miR-340 in gastric cancer cell proliferation and apoptosis and to elucidate the potential mechanisms.

Knockdown of Minichromosome Maintenance Proteins Inhibits Foci Forming of Mediator of DNA-Damage Checkpoint 1 in Response to DNA Damage in Human Esophageal Squamous Cell Carcinoma TE-1 Cells.

Esophageal squamous cell carcinoma (ESCC) has a high morbidity in China and its treatment depends greatly on adjuvant chemotherapy. However, DNA damage repair in cancer cells severely affects the outcome of treatment. This study investigated the potential mechanism regarding mediator of DNA-damage checkpoint 1 (MDC1) and minichromosome maintenance proteins (MCMs) during DNA damage in ESCC.
