GNAS, not a Highly Mutated Gene, Has Prognostic Significance and Carcinogenic Effects in Osteosarcoma.

Background/aims: Osteosarcoma is a prevalent and aggressive primary malignant bone tumor affecting children and adolescents. Despite advancements in sequencing technologies, there remains a lack of reliable prognostic biomarkers and effective targeted therapies for osteosarcoma. This study focuses on identifying key prognostic genes, particularly the role of GNAS, in osteosarcoma progression.

Inhibiting the expression of spindle appendix cooled coil protein 1 can suppress tumor cell growth and metastasis and is associated with cancer immune cells in esophageal squamous cell carcinoma.

Inhibiting the expression of spindle appendix cooled coil protein 1 (SPDL1) can slow down disease progression and is related to poor prognosis in patients with esophageal cancer. However, the specific roles and molecular mechanisms of SPDL1 in esophageal squamous cell carcinoma (ESCC) have not been explored yet. The current study aimed to investigate the expression levels of SPDL1 in ESCC via transcriptome analysis using data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus databases.

Intravascular ultrasonography assisted carotid artery stenting for treatment of carotid stenosis: Two case reports.

Background: Digital subtraction angiography (DSA), the gold standard of cerebrovascular disease diagnosis, is limited in its diagnostic ability to evaluate arterial diameter. Intravascular ultrasonography (IVUS) has advantages in assessing stenosis and plaque nature and improves the evaluation and effectiveness of carotid artery stenting (CAS).

Case Summary: Case 1: A 65-year-old man presented with a five-year history of bilateral lower limb weakness due to stroke.

In vitro bloodbrain barrier permeability study of four main active ingredients from Alpiniae oxyphyllae fructus.

The fruits of Alpinia oxyphylla Miq., a broadly utilized traditional Chinese medicine, have a number of effects on the central nervous system (CNS). The main active constituents of Alpiniae oxyphyllae fructus (AOF) were nootkatone, tectochrysin, chrysin and protocatechuic acid.

STIM1 controls calcineurin/Akt/mTOR/NFATC2-mediated osteoclastogenesis induced by RANKL/M-CSF.

Store-operated Ca entry (SOCE) is the stable calcium channel influx in most cells. It consists of the cytoplasmic ion channel ORAI and endoplasmic reticulum receptor stromal interaction molecule 1 (STIM1). Abolition of SOCE function due to ORAI1 and STIM1 gene defects may cause non-perspiration, ectoderm dysplasia and skeletal malformations with severe combined immunodeficiency (CID).

[Effect of xingnaojing injection combined with minimally invasive percutaneous drainage in treating brain edema and content of serum AQP4 in patients with moderate hypertensive basal ganglia hemorrhage].

Objective: To observe the effect of Xingnaojing Injection combined with minimally invasive percutaneous drainage on brain edema and content of serum aquaporin-4 (AQP4) in patients with moderate hypertensive basal ganglia hemorrhage, and discuss the treatment mechanism of Xingnaojing injection combined with minimally invasive percutaneous drainage for cerebral hemorrhage.

Method: Forty-two patients with moderate (25-50 mL) hypertensive basal ganglia hemorrhage (< 24 h) were selected and randomly divided into two groups: the observation group (n = 22) and the control group (n = 20). The neurological severity score were evaluated by the NIHSS (national institutes of health stroke scale), the volume of brain edemas were measured by head CT, the serum levels of AQP4 were determined by ELISA method on admission and 1 and 2 weeks after treatment.
