Article Synopsis
- Cerebral vasospasm (CV) is a serious complication after a brain hemorrhage, and endovascular therapy, especially intra-arterial vasodilator infusion (IAVI), is being evaluated as a new treatment option.
- A systematic review and meta-analysis found that patients receiving endovascular therapy had significantly lower in-hospital mortality rates compared to those who received standard treatment, although other long-term recovery measures showed no significant difference.
- Patients undergoing endovascular therapy experienced longer stays in the ICU and total hospital time, suggesting that while it may reduce mortality, it may lead to increased healthcare resource use.
Background: Carotid cavernous fistula (CCF) refers to the abnormal arteriovenous communication between the carotid system at the skull base and the sphenoid cavernous sinus, which is caused by trauma in almost 75% of cases. The drainage of venous blood to the spinal cord represents a distinctive mechanism, which is commonly observed in dural arteriovenous fistula (DAVF), and typically manifests clinically as progressive myelopathy. However, it is a rare occurrence in clinical practice that traumatic carotid cavernous fistula (TCCF) causes delayed quadriplegia through perimedullary venous drainage.

Methods: A total of 95 paraffin-embedded samples of tumorous tissue of HNSCC were collected. Expression levels of PD-1, PD-L1, and P16 were determined by immunohistochemistry.
Objective: Several studies have been performed to investigate the association between SMAD3 gene polymorphism and osteoarthritis (OA), but the results were inconclusive. This study aims to determine whether SMAD3 polymorphism is associated with risk of OA.
Method: A comprehensive literature search in PubMed, Embase, and ISI Web of Science for relevant studies was performed.
Aims: Postmenopausal osteoporosis is a bone metabolism disease that is caused by an imbalance between bone-resorbing osteoclast and bone-forming osteoblast actions. Herein, we describe the role of troxerutin (TRX), a trihydroxyethylated derivative of rutin, in ovariectomy (OVX)-induced osteoporosis and its effects on the regulation of osteoclasts and osteoblasts.
Main Methods: In vivo, OVX female mice were intraperitoneally injected with either saline, 50 mg/kg TRX, or 150 mg/kg TRX for 6 weeks and then sacrificed for micro-computed tomography analyses, histological analyses, and biomechanical testing.
