Rat models of liver fibrosis were made by carbon tetrachloride, and the serum levels of AST, ALT, γ-GT, MDA, GSH-px, SOD were detected, serum markers of PCⅢ, IV-C, LN, HA were detected by ELISA method. HE and Masson staining were conducted in hepatic tissues to observe pathological variations. Collagen Ⅲ, TGF-β, α-SMA, E-cadherin were detected by Western blot. The curative effect of the extract of Ornithogalum caudatum on rat liver fibrosis induced by CCl4was observed and the mechanism was discussed. The experiment results showed that the extract of O. caudatum (50, 150, 500 mg•kg⁻¹) obviously decreased the serum levels of AST, ALT, γ-GT, MDA, increased the serum levels of GSH-px, SOD, decreased the expression of serum markers of PCⅢ, IV-C, LN, HA, and improved the liver pathological variations of fibrotic rats. The experiment proved that the extract of O. caudatum could treat the liver fibrogenesis induced by CCl4 in rats. The positive medicine may inhibit accumulation of extracellular and activate hepatic stellate cell and epithelial-mesenchymal transition.

Background: The hypobaric hypoxic atmosphere can cause adverse reactions or sickness. The purpose of this study was to explore the preventive effect and mechanism of human umbilical cord mesenchymal stem cells (hUC-MSCs) on acute pathological injury in mice exposed to high-altitude.
Methods: We pretreated C57BL/6 mice with hUC-MSCs via the tail vein injection, and then the mice were subjected to hypobaric hypoxic conditions for five days.
Exploring factors associated with Kidney Disease Quality of Life in patients with advanced chronic kidney disease: the Reach-J CKD cohort study.
Clin Exp Nephrol
January 2025
Reach-J Steering Committee, Tsukuba, Ibaraki, Japan.
Background: Although several studies have examined the Kidney Disease Quality of Life (KDQOL) in patients with chronic kidney disease (CKD), the factors associated with kidney-related symptoms have not been fully explored.
Methods: This nationwide multicenter cohort study enrolled 2248 patients. To identify the factors associated with each item or the three KDQOL domains, such as burden of kidney disease, symptoms/problems of kidney disease, and impact of kidney disease on daily life, multiple regression analysis was performed using baseline data.
Association between sleep quality and serum biomarkers among long-term hot spring bathers: a cross-sectional study.

Previous studies investigating the influence of hot spring bathing on sleep quality have predominantly focused on the short-term effects through questionnaire surveys without blood collection for biochemical tests. Here, we undertook a comprehensive investigation of the long-term health effects of hot spring bathing among the residents of Hot Spring Village. A total of 140 participants were enrolled, and their demographic characteristics and the patterns of hot spring bathing were obtained via face-to-face interview, and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI).

Purpose: This study aims to investigate whether zinc ion (Zn) alleviates myocardial ischemia-reperfusion injury (MIRI) through the MAM-associated signaling pathway and to explore its impact on ERS and calcium overload.
Methods: H9C2 cells were cultured in a DMEM supplemented with 10 % fetal bovine serum and 1 % antibiotic solution. A MIRI model was established through simulated ischemia and reoxygenation with Zn treatment in a complete medium.

Diabetic neuropathic pain (DNP) is a common complication of diabetes mellitus (DM) and is characterized by spontaneous pain and neuroinflammation. The Sigma-1 receptor (Sig-1R) has been proposed as a target for analgesic development. It is an important receptor with anti-inflammatory properties and has been found to regulate DNP.
