Causal association of serum vitamin D levels with urolithiasis: a bidirectional two-sample Mendelian randomization study.

Background: In light of inconsistent evidence from previous observational studies regarding the correlation between serum vitamin D levels and urolithiasis, this study aimed to investigate the genome-wide causal association between genetically predicted serum 25(OH)D levels and urolithiasis using the Mendelian randomization (MR) approach.

Methods: In this study, we utilized genome-wide association studies (GWAS) summary statistics from the UK Biobank and SUNLIGHT consortium for serum vitamin D levels, as well as urolithiasis data from FinnGen. We employed bidirectional two-sample MR analysis to evaluate potential causal relationships.

Evaluation of safety and efficacy of intracranial self-expanding drug-eluting stents for symptomatic intracranial atherosclerotic stenosis: a prospective, multicentre, randomised controlled, superiority clinical trial protocol.

Background: In-stent restenosis (ISR) is a crucial factor that affects the long-term efficacy of intracranial bare metal stent (BMS) implantation for intracranial atherosclerotic stenosis (ICAS). Patients with intracranial ISR are at a high risk of recurrent ischaemic events. The NOVA intracranial drug-eluting stent (DES) trial demonstrates that a DES can reduce ISR and stroke recurrence after intracranial bare stent implantation.

Safety and efficacy of intralesional rituximab injection versus involved site radiation therapy in primary ocular adnexal MALT lymphoma: study protocol for a multicentre randomised controlled trial.

Introduction: Involved site radiation therapy (ISRT) is a widely used treatment for primary ocular adnexal mucosa-associated lymphoid tissue (MALT) lymphoma with control rates over 85%; however, its complications could reach 30%-50%. Intralesional rituximab injection has shown promising results with remission rates between 65% and 100% and minimal complications. This study aimed to conduct a multicentre randomised controlled clinical trial to compare the safety and efficacy of intralesional rituximab injection versus ISRT on primary ocular adnexal MALT lymphoma.

Wearable Patch ECG monitors and transesophageal electrophysiological study for diagnosing palpitations of unknown origin.

Objective: To analyze the application value of wearable adhesive Patch ECG monitors combined with transesophageal electrophysiological study (TEPS) in the diagnosis of palpitations of unknown origin.

Methods: This was a retrospective study of patients with suspected arrhythmia who were admitted to Henan Provincial People's Hospital between October 2021 and July 2023 due to recurrent paroxysmal palpitations of unknown origin, with or without accompanying symptoms such as dizziness, amaurosis, and syncope. All patients underwent TEPS.

Comparisons of efficacy and safety of 400 or 800 ml bacterial count fecal microbiota transplantation in the treatment of recurrent hepatic encephalopathy: a multicenter prospective randomized controlled trial in China.

Background: Hepatic encephalopathy (HE) represents a critical complications of end-stage liver disease, serving as an independent predictor of mortality among patients with cirrhosis. Despite effective treatment with rifaximin, some patients with HE still progress to recurrent episodes, posing a significant therapeutic challenge. Recurrent HE is defined as experiencing two or more episodes within a 6-month period.

An in vitro biomechanical evaluation of integrated lateral plate combined with oblique lateral interbody fusion in different bone conditions.

Oblique lateral interbody fusion (OLIF) is a minimally invasive surgery for the treatment of lumbar degenerative diseases (LDD). Under normal bone mass(NB), supplemental with lateral plate (LP) fixation has been proven to provide stability and reduce complications. However, it is unclear whether OLIF combined with LP fixation can achieve satisfactory fixation effects in cases of osteoporosis(OP) or osteopenia (OS)? In this study, Eighteen L3-5 spinal specimens from 3 to 6 months old fresh calves were equally divided into 3 groups: group A (NB), group B (OS) and group C (OP).

[Efficacy analysis of 3D printing prefixed nail path model assisted lumbar and sacral hemivertebra orthopaedic surgery].

Objective: To analyze the safety and effectiveness of 3D printing prefabricated nail path model assisted lumbosacral hemivertebra orthopaedic surgery.

Methods: A retrospective analysis was performed on 8 patients with lumbosacral hemivertebra deformity admitted from January 2016 to July 2021, including 3 males and 5 females, aged 6 to 15 at the time of surgery. The hemivertebra of 4 cases located on the left side and 4 cases on the right side.

Transcriptome analyses reveal molecular mechanisms of novel compound heterozygous variants causing infantile cerebellar retinal degeneration.

Background And Purpose: Infantile cerebellar retinal degeneration (ICRD) (OMIM #614559) is a rare autosomal recessive inherited disease associated with mutations in the aconitase 2 (ACO2) gene. We report a Chinese girl with novel compound heterozygous variants in , who presented at 7 months of age with psychomotor retardation, truncal hypotonia, and ophthalmologic abnormalities. This study aims to investigate the potential molecular mechanisms underlying deficiency-induced neuropathy.

Regulation of Ankyrin-G on Nav1.5 Channel in Hypoxic HL-1 Cardiac Muscle Cells.

Background: Hypoxia has a major regulatory impact on the electrical activity transmission in the myocardium, and it is involved in the development of tachyarrhythmia disease. Anchor protein G (ankyrin-G, ANK-G) is associated with voltage-gated Na channels (Nav1.5), but its specific role and mechanism have not been fully defined.

A Self-Calibrating Fluorescent-Photoacoustic Integrated Probe Enables Fast Visualizing Pancreatic Cancer and Imaging-Guided Tumor Surgery.

Pancreatic cancer is known for its high invasiveness and metastasis, making rapid visualization and precise treatment critical for improving patient outcomes. Current diagnostic tools lack abilities to provide rapid and accurate tumor localization, particularly for real-time intraoperative guidance. To address this gap, the study has developed a novel Förster Resonance Energy Transfer (FRET)-mediated dual-ratiometric near-infrared fluorescence (NIRF)/photoacoustic (PA) bimodal probe, SiRho-SHD-NTR, specifically designed for the fast and accurate navigation of pancreatic tumor resection.

A nanoporous electrochemical aptamer-based sensors for rapid detection of cardiac troponin I in blood.

Acute myocardial infarction (AMI) is one of the top contributors to global disease mortality. AMI biomarkers, such as cardiac troponin I (cTnI), are often detected with enzyme-linked immunosorbent assay (ELISA) that suffers from several well-known drawbacks such as poor stability and slow and cumbersome operation. Therefore, it is necessary to develop a new analytical technique that can rapidly analyse and detect cTnI for early screening of AMI.

Methods: This prospective, multicenter, observational study enrolled patients with malignancies who received any generic nab-paclitaxel-based regimens in China. The primary endpoint was safety, and secondary endpoint was objective response rate (ORR).

Overexpression of the inwardly rectifying potassium channel Kir4.1 or Kir4.1 Tyr9 Asp in Müller cells exerts neuroprotective effects in an experimental glaucoma model.

Downregulation of the inwardly rectifying potassium channel Kir4.1 is a key step for inducing retinal Müller cell activation and interaction with other glial cells, which is involved in retinal ganglion cell apoptosis in glaucoma. Modulation of Kir4.

Novel biallelic variants in IREB2 cause an early-onset neurodegenerative disorder in a Chinese pedigree.

Background: Cellular iron metabolism is essential for maintaining various biological processes in organisms, and this is influenced by the function of iron-responsive element-binding protein 2 (IRP2), encoded by the IREB2 gene. Since 2019, three cases of a genetic neurodegenerative syndrome resulting from compound heterozygous mutations in IREB2 have been documented, highlighting the crucial role of IRP2 in regulating iron metabolism homeostasis. This study aims to investigate the molecular basis in a single proband born to non-consanguineous healthy parents, presenting with severe psychomotor developmental abnormalities and microcytic anemia.
