1.  Elevation of serum CXCL16 level correlates well with atherosclerotic ischemic stroke 
Introduction
Currently there are no reliable biological markers for ischemic stroke. The novel chemokine CXCL16 is known to be involved in the development of atherosclerosis. Nevertheless, the real role of CXCL16 in atherosclerotic disorders remains uncertain. The goal of our study was to investigate the associations between serum-soluble CXCL16 level and atherosclerotic ischemic stroke, including large artery atherosclerosis (LAA) and small artery occlusion (SAO) subtypes, and to explore whether elevation in CXCL16 levels is correlated with the severity of large arterial stenosis.
Material and methods
The study recruited 227 subjects, including 74 controls and 153 consecutive patients with acute ischemic stroke from atherosclerosis of the carotid artery. The etiology of the acute ischemic strokes was classified into LAA (n = 86) subtype and SAO (n = 67) subtype according to the TOAST criteria, and the severity of carotid artery stenosis was assessed by the NASCET criteria. Serum-soluble CXCL16 concentration was measured by enzyme-linked immunosorbent assay.
Results
Serum CXCL16 concentrations were significantly increased in both LAA (2.36 ng/ml) and SAO subtypes (2.13 ng/ml) when compared to that of the controls (2.04 ng/ml, p < 0.01 and p < 0.05, respectively), and it was significantly elevated in LAA subtype than in SAO subtype (p < 0.05). However, significant differences in CXCL16 levels between the high-grade stenosis group (2.36 ng/ml) and moderate-grade stenosis group (2.24 ng/ml) of LAA subtype were not found (p > 0.05). A correlation of serum levels of CXCL16 with serum levels of hs-CRP, fibrinogen and lipid parameters was not observed (p > 0.05).
Conclusions
Increased serum level of soluble CXCL16 was independently associated with atherosclerotic ischemic stroke, particularly LAA subtype.

2.  Vertebral artery dissection associated with viral meningitis 
BMC Neurology  2012;12:79.
Background
Vertebral artery dissection (VAD) is often associated with trauma or occurs spontaneously, inevitably causing some neurological deficits. Even though acute infection can be related to the development of spontaneous VAD (sVAD), VAD associated with viral meningitis has never been reported in the literature.
Case presentation
A 42-year-old man with fever, sore throat, and runny nose developed sudden onset of occipital headache, vertigo, transient confusion, diplopia, and ataxia. Brain stem encephalitis was diagnosed initially because the cerebrospinal fluid (CSF) study showed inflammatory changes. However, subsequent diffusion-weighted (DWI) magnetic resonance imaging of his brain demonstrated left lateral medullary infarction, and the digital subtraction angiography (DSA) confirmed VAD involving left V4 segment of the artery. Consequently, the patient was diagnosed as VAD accompanied by viral meningitis.
Conclusion
This case suggests that viral meningitis might lead to inflammatory injury of the vertebral arterial wall, even sVAD with multiple neurological symptoms.
