    Abstract

    Magnetic resonance imaging of spinal dural arteriovenous fistula (SDAVF) shows longitudinally extensive spinal cord lesions mimicking neoplastic or inflammatory myelopathy. On positron emission tomography/computed tomography (PET/CT), we report two patients who showed focal 18F‐fluorodeoxyglucose (FDG) uptake in longitudinally extensive spinal cord lesions. These lesions were indistinguishable from tumors or myelitis but were finally diagnosed as SDAVF. Although PET/CT availability may be limited, in cases of myelopathy with diagnostic challenges, it is important to recognize that focal FDG uptake can be observed in SDAVF.

    BACKGROUND: We aimed to develop quality indicators (QIs) related to primary and comprehensive stroke care and examine the feasibility of their measurement using the existing Diagnosis Procedure Combination (DPC) database. METHODS AND RESULTS: We conducted a systematic review of domestic and international studies using the modified Delphi method. Feasibility of measuring the QI adherence rates was examined using a DPC-based nationwide stroke database (396,350 patients admitted during 2013-2015 to 558 hospitals participating in the J-ASPECT study). Associations between adherence rates of these QIs and hospital characteristics were analyzed using hierarchical logistic regression analysis. We developed 17 and 12 measures as QIs for primary and comprehensive stroke care, respectively. We found that measurement of the adherence rates of the developed QIs using the existing DPC database was feasible for the 6 QIs (primary stroke care: early and discharge antithrombotic drugs, mean 54.6% and 58.7%; discharge anticoagulation for atrial fibrillation, 64.4%; discharge antihypertensive agents, 51.7%; comprehensive stroke care: fasudil hydrochloride or ozagrel sodium for vasospasm prevention, 86.9%; death complications of diagnostic neuroangiography, 0.4%). We found wide inter-hospital variation in QI adherence rates based on hospital characteristics. CONCLUSIONS: We developed QIs for primary and comprehensive stroke care. The DPC database may allow efficient data collection at low cost and decreased burden to evaluate the developed QIs.

    Objective : With advent of an endovascular suite in the operating room (hybrid OR), it has been reported recently that combination therapy with surgical and endovascular procedures in hybrid OR for complex cerebrovascular diseases is feasible. / Materials and methods : We analyzed the 15 consecutive cases who underwent combination therapy with hybrid OR in our hospital from October 2014 to September 2017 (8 Aneurysms, 3 carotid artery stenosis, and 4 dural arteriovenous fistulas (DAVF)). / Results : All procedures were performed successfully. We performed bypass surgery and endovascular trapping with endovascular procedure for all aneurysm cases. In 3 cases of carotid artery stenosis, we performed carotid artery stenting (CAS) with direct puncture of common carotid artery for 2 cases and rescue stenting with carotid endarterectomy for 1 case. Perioperative antiplatelet therapy was performed in all cases of unruptured aneurysms and carotid artery stenosis. In the cases of DAVF, we performed transarterial or transvenous embolization combined with craniotomy, or shunt ligation with selective indocyanine green videoangiography using microcatheter. Systemic full heparinization was performed during all endovascular procedures. There was no symptomatic hemorrhagic and ischemic complication. There was no neurological deterioration of modified Rankin scale at discharge except for the case of symptomatic hyperperfusion after CAS. / Conclusion : Combination therapy with hybrid OR for complex cerebrovascular disease is safe and feasible.

    Central nervous system (CNS) pericytes have been recognized as an indispensable component of the neurovascular unit. The expression of platelet-derived growth factor receptor β (PDGFRβ) is markedly increased in CNS pericytes after brain ischemia. It has been elucidated that PDGFRβ, expressed in pericytes and pericyte-derived fibroblast-like cells, plays important roles in the maintenance of the blood-brain barrier (BBB) and in the repair process in infarct areas. The aim of this study was to uncover how the PDGFRβ expression is regulated in pericytes after brain ischemia. We found that basic fibroblast growth factor (bFGF), but neither hypoxia at 1% O2 nor acidification at pH 6.5, significantly upregulated the PDGFRβ expression in human cultured CNS pericytes. SU5402, an inhibitor of FGF receptor (FGFR), and inhibitors of its downstream effectors Akt and Erk abolished the bFGF-induced upregulation of PDGFRβ. On the other hand, acidification significantly upregulated the expression of bFGF, while hypoxia upregulated the expression of FGFR1 in the pericytes. The expression of bFGF and FGFR1 was markedly induced in the ischemic hemisphere after ischemic insult in a middle cerebral artery occlusion stroke model. Immunofluorescent double labeling demonstrated that the expression of bFGF and FGFR1 was co-localized with PDGFRβ-positive cells in peri-infarct areas. Moreover, treatment with bFGF enhanced cell growth and the PDGF-BB-induced migratory activity of cultured pericytes, which were significantly suppressed by SU5402 or Sunitinib, an inhibitor of PDGFR. These data suggested that increased bFGF upregulates the expression of PDGFRβ and may enhance PDGFRβ-mediated pericyte functions after brain ischemia.

    Language:English   Publishing type:Research paper (scientific journal)  

    Fibrosis is concomitant with repair processes following injuries in the central nervous system (CNS). Pericytes are considered as an origin of fibrosis-forming cells in the CNS. Here, we examined whether platelet-derived growth factor receptor β (PDGFRβ), a well-known indispensable molecule for migration, proliferation, and survival of pericytes, was involved in the production of extracellular matrix proteins, fibronectin and collagen type I, which is crucial for fibrosis after ischemic stroke. Immunohistochemistry demonstrated induction of PDGFRβ expression in vascular cells of peri-infarct areas at 3-7days in a mouse stroke model. The PDGFRβ-expressing cells extended from peri-infarct areas toward the ischemic core after day 7 while expressing fibronectin and collagen type I in the infarct areas. In contrast, desmin and α-smooth muscle actin, markers of pericytes, were only expressed in vascular cells. In PDGFRβ heterozygous knockout mice, the expression of fibronectin and collagen type I was attenuated at both mRNA and protein levels with an enlargement of the infarct volume after ischemic stroke compared with that in wild-type littermates. In cultured brain pericytes, the expression of PDGF-B, PDGFRβ, fibronectin, and collagen type I, but not desmin, was significantly increased by serum depletion (SD). The SD-induced upregulation of fibronectin and collagen type I was suppressed by SU11652, an inhibitor of PDGFRβ, while PDGF-B further increased the SD-induced upregulation. In conclusion, the expression level of PDGFRβ may be a crucial determinant of fibrosis after ischemic stroke. Moreover, PDGFRβ signaling participates in the production of fibronectin and collagen type I after ischemic stroke.

    Language:English   Publishing type:Research paper (scientific journal)  

    OBJECTIVE: We have previously shown that Na(+)/H(+) exchanger isoform 1 (NHE1) plays an important role in Ca(2+) signaling and cell proliferation in human central nervous system (CNS) pericytes. The aims of the present study were to elucidate how NHE1-induced Ca(2+) signaling during acidosis is transformed into cellular responses in CNS pericytes. METHODS AND RESULTS: Human CNS pericytes were cultured, and the activation of cAMP responsive element-binding protein (CREB) was evaluated by Western blotting analysis, immunofluorescence, and luciferase assays. In human CNS pericytes, low extracellular Na(+) or low pH generated Ca(2+) oscillation and subsequently phosphorylated Ca(2+)/calmodulin-dependent kinase II (CaMKII) and CREB in a time-dependent manner. Focal cerebral ischemia was applied using photothrombotic distal middle cerebral artery occlusion in mice, and the phosphorylation of CREB and the production of interleukin-6 were observed in pericytes migrating into the peri-infarct penumbra during the early phase after ischemic insult. CONCLUSIONS: Our results indicate that extracellular acidosis induces Ca(2+) oscillation via NHE1, leading to Ca(2+)/CaMKII-dependent CREB activation in human CNS pericytes. Acidosis may upregulate a variety of proteins, such as interleukin-6, through the NHE1-Ca2+/CaMKII-CREB pathway in brain pericytes and may thus modulate brain ischemic insult.

    Language:English   Publishing type:Research paper (scientific journal)  

    Platelet derived growth factor (PDGF)-B plays a neuroprotective role in brain damages, including ischemic stroke. It has been suggested recently that PDGF receptor β (PDGFRβ) expressed in brain pericytes as well as in neurons and astrocytes may mediate the neuroprotective role of PDGF-B. The aims of this study were to elucidate the roles of PDGFRβ signaling in brain pericytes after ischemic stroke. In a rat middle cerebral artery occlusion (MCAO) model, PDGFRβ expression was induced specifically in the pericytes in peri-infarct areas and its level was gradually increased. PDGF-B induced marked phosphorylation of Akt in cultured brain pericytes. Consistently, PDGF-B was upregulated in endothelial cells in per-infarct areas and Akt was strongly phosphorylated in the PDGFRβ-expressing pericytes in periinfarct areas after MCAO. In the cultured pericytes, PDGF-B induced cell growth and anti-apoptotic responses through Akt. Furthermore, PDGF-B significantly increased the expression of nerve growth factor (NGF) and neurotrophin-3 (NT-3) through Akt in the pericytes. Thus, the PDGFRβ-Akt signaling in brain pericytes may play various important roles leading to neuroprotection after ischemic stroke.
