Esophageal variceal (EV) diameter is a critical, independent risk factor for hemorrhage, and plays a key role in guiding choices of endoscopic treatment techniques. We developed a novel tool, the virtual ruler (VR), which offers increased precision and expediency in EV diameter (EVD) measurements. This study investigates the clinical value of VR for assessing EVD during the endoscopic treatment of cirrhotic EVs.

Article Synopsis
  • A 2D flexible hydrogel (GO/CNF) is created by combining graphene oxide (GO) with cellulose nanofiber (CNF) using microwave-assisted hydrothermal methods, resulting in a superhydrophilic material with a layered structure.
  • * The optimal mass ratio of GO to CNF is 3:1, leading to a specific capacitance of 295 F/g and improved electrochemical performance when used as free-standing electrodes in a three-electrode system.
  • * The enhanced properties of the hydrogel, especially at a press pressure that increases hydrophilicity, suggest its potential for use in flexible solid-state supercapacitors, wearable electronics, and biological signal detection with a high energy density of 20.6

Article Synopsis
  • The study investigates the correlation between esophageal variceal diameter (EVD) and portal pressure gradient (PPG) as a potential non-invasive indicator of bleeding risk in patients with portal hypertension.
  • Utilizing an AI-based method for measuring EVD, researchers analyzed data from 128 patients, revealing a significant positive correlation between EVD and PPG.
  • Results showed that patients with higher PPG had larger EVD, and EVD proved to be a reliable predictor of elevated PPG levels, suggesting its clinical utility in managing patients at risk for bleeding.

Article Synopsis
  • * Researchers utilized various statistical methods, including Cox regression and ROC analysis, to evaluate and validate CTARSig's effectiveness and to characterize the tumor immune environment in STAD patients.
  • * The study identified eleven key CTA-related genes for CTARSig, revealing that high levels of the gene ELOVL4 are linked to poor survival outcomes and increased metastatic behavior in gastric cancer, suggesting it could be a promising target for future therapies.

Background: Glutamine Synthetase (GS) could induce vascular sprouting through the improvement of endothelial cell migration in inflammatory diseases. MR vessel-size imaging has been proposed as a valuable approach for visualizing the underlying angiogenic processes in the brain.

Objective: This study aims to investigate the role of GS in the neovascularization of gliomas through the utilization of MR vessel-size imaging and histopathological techniques.

Molecular triplet-triplet annihilation upconversion often experiences drastic luminescence quenching in the presence of oxygen molecules, posing a significant constraint on practical use in aerated conditions. We present an oxygen-immune near-infrared triplet-triplet annihilation upconversion system utilizing non-organometallic cyanine sensitizers (λ = 808 nm) and chemically synthesized benzo[4,5]thieno[2,3-b][1,2,5]thiadiazolo[3,4-g]quinoxaline dyes with a defined dimer structure as annihilators (λ = 650 nm). This system exhibits ultrastable upconversion under continuous laser irradiance (>480 mins) or extended storage (>7 days) in aerated solutions.

Article Synopsis
  • HORMAD1 is a cancer/testis antigen that has been found to be significantly upregulated in gastric cancer, correlating with poor prognosis.
  • Research showed that HORMAD1 influences cancer cell growth and invasion by affecting the NF-κB signaling pathway and promoting the epithelial-mesenchymal transition (EMT).
  • HORMAD1 may serve as a valuable prognostic biomarker and potential therapeutic target for gastric cancer treatment.

Marine biological activities make a non-negligible contribution to atmospheric aerosols, leading to potential impacts on the regional atmospheric environment and climate. The eastern China seas are highly productive with significant emissions of biogenic substances, but the spatiotemporal variations of marine biogenic aerosols are not well known. Air mass exposure to chlorophyll (AEC) can be used to indicate the influence of biogenic sources on the atmosphere to a certain degree.

  • Traditional plain radiographs for intraoperative spinal level localization (SLL) can be inaccurate due to obstructions from shoulders and scapulae; this study investigated using oblique radiographs with methylene blue markings to improve accuracy.
  • The study involved 33 patients with upper thoracic spine lesions, showing that oblique radiographs effectively visualized structures and recorded median times for radiographing and operation.
  • The findings suggest that this technique enhances the precision of locating lesions during surgery while minimizing radiation exposure and shortening operation time.

Purpose: The formation mechanism of spinal extradural arachnoid cysts (SEACs) remains unclear. There are several hypotheses for the formation of SEACs, but none of them can fully explain its pathological findings and surgical procedures. In this study, we retrospectively analyzed the cases of SEACs, aiming to clarify the formation mechanism of SEACs.

In this study, we intended to describe a human case of lumbosacral canal sparganosis in People's Republic of China (China). A 56-year-old man was admitted to Xiangya Hospital Central South University in Changsha, Hunan province, China after having an experience of perianal pain for a week. An enhancing mass, a tumor clinically suggested, was showed at the S1-S2 level of the lumbosacral spine by the examination of magnetic resonance imaging (MRI) with gadolinium contrast.

The aim of the present study was to investigate the expression and prognostic value of microRNA-135a (miR-135a) and matrix metalloproteinase-13 (MMP-13) in serum of colon cancer (CC). A total of 117 cases of patients admitted to Sheng Li Oil Field Central Hospital from May 2015 to May 2017 were enrolled in the research group (RG), and 120 cases of subjects undergoing normal health examination were included in the control group (CG). The expression of miR-135 and MMP-13 in peripheral blood of the two groups were compared, and their values were analyzed.

Background: Intracorporeal rectal transection at the anorectal junction for ultralow rectal cancer is technically difficult due to pelvic width and limited roticulation, which might require a transanal transection or an oblique transection with multiple firings. These procedures were reported to be associated with the increased risk of morbidity. To address these problems, we presented a novel technique Transanterior Obturator Nerve Gateway (TANG) to transect rectum for ultralow rectal cancer and evaluated its safety and feasibility in this study.

Dysregulation of gene expression, often interpreted by gene transcription as an endpoint response, is tightly associated with human cancer. Long noncoding RNAs (lncRNAs), derived from the noncoding elements in the genome and appeared no less than 200nt in length, have emerged as a novel class of pivotal regulatory component. Recently, great attention has been paid to the cancer-related lncRNAs and growing evidence have shown that lncRNAs act as key transcriptional regulators in cancer cells through diverse mechanisms.

Temozolomide (TMZ) is one of the most commonly used drugs for the clinical treatment of glioblastomas. However, it has been reported that treatment with TMZ can induce autophagy, which leads to tumor resistance and increases the survival of tumor cells. MicroRNA-30a (miR-30a) has been found to have inhibitory effects on autophagy by directly targeting beclin 1.

Cervical cancer is a common cancer among women and has a high morbidity and mortality. The traditional clinical methods for cervical cancer screening are invasive and limited in terms of cost and time. There is an unmet clinical need for new methods to aid clinicians in the rapid screening and auxiliary diagnosis of cervical precancer.

Aim: The present study aimed to examine the effect of tumor necrosis factor-α (TNF-α) inhibition on bone marrow-derived mesenchymal stem cells (BMSCs) in neurological function recovery after spinal cord injury (SCI) via the Wnt signaling pathway in a rat model.

Methods: The rat model of SCI was established using Allen's method. Seventy-two adult male Sprague Dawley (SD) rats were randomly assigned into 4 groups (18 rats in each group): the sham control group, saline control group, BMSCs group (injection with BMSCs at the injured site) and BMSCs + TNF-α group (injection with BMSCs under TNF-α treatment at the injured site).
