Although RD did not exert significant effects on primary endpoint, RD significantly prevented CVS and reduced SAH-induced increases in the number of phosphorylated extracellular signal-regulated kinase (ERK)-positive endothelial cells, cyclooxygenase-2 expression, and macrophage infiltration in major cerebral arteries.
As per institutional protocol, all patients with CVS detected in the posterior circulation had magnetic resonance imaging (MRI) examinations instead ofCTA.

BACKGROUND The aim of this study was to investigate the protective effect of ADM gene mediated by plasmid pVAX1 on cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH).
CONCLUSIONS The recombinant eukaryotic expression plasmid pVAX1-ADM can significantly relieve cerebral vasospasm, increase the expression of serum ADM and NOS, and decrease the expression of serum ET-1 in a rat model of CVS; it is dose-dependent and can also improve nervous system function.

Cumulative levels measured over two weeks showed significant correlations with post-SAH complications including a negative correlation of D-Loop with pneumonia infection, hydrocephalus and occurrence of epilepsy, a positive correlation of Cyt B with occurrence of CVS and a negative correlation of COX-1 with occurrence of systemic infections and seizures.
In our consecutive series of 2,574 chorionic villus sampling (CVS) patients, 146 women (5.7%) underwent a subsequent amniocentesis in the same pregnancy for the indications of absent or insufficient villi (3.3%), elevated maternal serum alpha-fetoprotein (0.93%), CVS mosaicism (0.89%), culture failure (0.23%), specimen contamination (0.15%), and CVS aneuploidy (0.12%).
Our results show for the first time that the variations in CNR1 and OPRM1 genes are associated with CVS and that different genotypes may contribute to the risk of CVS.

Our results suggest that an early and persistent decrease in KLF4 followed by an increase in miR-15a may contribute to the altered vascular phenotype, resulting in development of CVS.

The higher the Hunt grade was, the higher the factor expression was; the expression levels of IL-6, CRP, S100 and NO in CSF were gradually increased in CVS group and unfavorable prognosis group, and the differences were significant compared with those in the control group.
