miR-let-7c-3p targeting on Egr-1 contributes to the committed differentiation of leukemia cells into monocyte/macrophages.

In preliminary experiments, it was found that the expression of early growth response-1 (Egr-1) was upregulated during the committed differentiation of leukemia cells into monocytes/macrophages. The cross-analysis of gene chip detection and database prediction indicated that Egr-1 was associated with upstream microRNA (miR)-let-7c-3p, thus the present study focused on the role of the miR-let-7c-3p/Egr-1 signaling axis in the committed differentiation of leukemia cells into monocytes/macrophages. Phorbol 12-myristate 13-acetate (PMA) was used to induce the directed differentiation of human K562 leukemia cells into monocytes/macrophages and the differentiation of K562 leukemia cells was determined by cell morphology observation and expression of differentiation antigens CD11b and CD14 by flow cytometry.

Vitamin E-coated dialyzer alleviates erythrocyte deformability dysfunction in patients with end-stage renal disease undergoing hemodialysis.

Patients with end-stage renal disease (ESRD) are characterized by augmented oxidative stress (OS) due to the imbalance between the generation of increased concentrations of oxidative molecules and decreased antioxidant capacity. Vitamin E-coated dialyzer membranes (VEMs) have previously been reported to alleviate the imbalance of redox metabolism in patients with ESRD undergoing hemodialysis (HD); however, their effect on the deformability of red blood cells (RBCs) remains unknown. In the present study, 48 patients with ESRD undergoing HD were enrolled and randomly assigned into two groups: HD with VEMs (VEM group; n=24) and HD with polysulfone dialyzer membranes (PM group; n=24), and another 24 healthy volunteers served as the control group.

Aim: To analyse the diagnostic value of magnetic resonance imaging (MRI)-based radiomics for triple-negative breast cancer (TNBC) by conducting a meta-analysis.

Materials And Methods: A comprehensive search was performed to identify relevant English articles concerning the MRI-based radiomics diagnosis of TNBC (from the date of database establishment to November 2021). The pooled sensitivity (SEN), pooled specificity (SPE), positive likelihood ratio (LR+), negative likelihood ratio (LR-), diagnostic odds ratio (DOR) with 95% confidence interval (CI), summary receiver operating characteristic (SROC) curve and area under the curve (AUC) for the accuracy of MRI-based radiomics in the diagnosis of TNBC were calculated.

Effect of Heptaflourane Inhalation and Anesthesia Induction on Hemodynamics of Elderly Patients Undergoing Elective Gastrointestinal Tumor Surgery.

Gastrointestinal stromal tumors (GISTs) are rare malignancies that begin in specific cells in the GI tract's (also known as the digestive tract's) wall. The microenvironment of gastrointestinal cancers has gotten a lot of interest in the last decade. There are various obstacles connected with providing care to individuals with gastrointestinal cancers, especially the elderly.

Observation on Application Effect of Arterial Puncture and Catheterization under Guidance of Intelligent Medical Care Ultrasound in Clinical Anesthesia.

In clinical anesthesia and the rescue of critically ill patients, arterial puncture and catheterization are the most commonly chosen ways to establish central arterial access for patients. Invasive arterial puncture and catheterization facilitate the grasp of real-time vital sign information of patients during surgery, which strengthens patient monitoring during surgery and improves safety. However, the traditional method of arterial puncture and cannulation through palpation of the radial artery is often prone to complications related to mechanical injury, such as hemorrhage, hematoma, and accidental perforation of the artery.

Newly Prepared 129Xe Nanoprobe-Based Functional Magnetic Resonance Imaging to Evaluate the Efficacy of Acupuncture on Intractable Peripheral Facial Paralysis.

This study focused on the application value of the newly prepared 129Xe nanoprobe-based functional magnetic resonance imaging (fMRI) in exploring the mechanism of the acupuncture treatment for intractable facial paralysis, expected to provide a theoretical reference for the mechanism of acupuncture for the treatment of facial paralysis. In this study, 30 patients with intractable peripheral facial paralysis (experimental group) and 30 healthy volunteers (control group) were selected. All patients were scanned by the newly prepared 129Xe nanoprobe-based fMRI technology, and then brain functional status data and rating data were collected.

MiR-17-5p protects neonatal mice from hypoxic-ischemic brain damage by targeting Casp2.

Hypoxia-ischemia brain damage (HIBD) is a leading cause of neonatal death worldwide, which significantly influences the development of newborns; however, effective treatment strategies remain limited. Recent studies have discovered that microRNAs (miRNAs) play essential roles in the progression of HIBD. Our study was designed to explore whether miR-17-5p was involved in the pathological development of HIBD.
