Abstract
BACKGROUND Circular RNAs (circRNA) have been reported to be involved in the progression of cerebral infarction. The purpose of this study was to reveal the role and potential molecular mechanism of circZfp609 (mmu_circ_0001797) in cerebral infarction. METHODS C57BL/6J mice was used to construct middle cerebral artery occlusion (MCAO) mice model, and primary mouse astrocytes were treated with oxygen-glucose deprivation/reperfusion (OGD/R) process. The circZfp609, microRNA (miR)-145a-5p and BTB and CNC homology 1 (BACH1) expression levels were detected by quantitative real-time PCR. Cell proliferation and apoptosis were assessed by cell counting kit 8 assay, EdU assay and flow cytometry. Western blot analysis was used to measure protein levels, and ELISA assay was utilized to detect the levels of inflammation factors. Lactate dehydrogenase (LDH) level was measured by LDH Assay Kit. Dual-luciferase reporter assay, RIP assay and RNA pull-down assay were used to evaluate RNA interaction. RESULTS CircZfp609 was upregulated in MCAO mice and OGD/R-induced astrocytes. Knockdown of circZfp609 promoted cell proliferation, while suppressed apoptosis and inflammation in OGD/R-induced astrocytes. CircZfp609 served as a sponge for miR-145a-5p, and miR-145a-5p inhibitor reversed the regulation of circZfp609 knockdown on OGD/R-induced astrocyte injury. BACH1 was a target of miR-145a-5p, and its overexpression abolished the inhibition effect of miR-145a-5p on OGD/R-induced astrocyte injury. Besides, circZfp609 downregulation also relieved the brain injury of MCAO mice through miR-145a-5p/BACH1 axis. CONCLUSION Our data showed that circZfp609 might promote cerebral infarction by regulating the miR-145a-5p/BACH1 pathway.

Acute Onset Quadriplegia and Stroke: Look at the Brainstem, Look at the Midline. J Clin Med 2022; 11:jcm11237205. [PMID: 36498778 PMCID: PMC9740674 DOI: 10.3390/jcm11237205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 11/24/2022] [Accepted: 12/01/2022] [Indexed: 12/12/2022] Open
Abstract
Acute onset quadriplegia with or without facial sparing is an extremely rare vascular syndrome, and the main focus of attention is on the cervical and upper thoracic spinal cord as the putative site of the damage. Quadriplegia has been occasionally reported in brainstem strokes within well-defined lesion patterns, but these reports have gained little attention so far because of the rarity of this clinical syndrome. The clinical, neuroanatomical and neuroimaging features of ischemic stroke locations associated with quadriplegia have been collected and reviewed in a pragmatical view, which includes a detailed description of the neurological signs associated with the damage of the pyramidal pathways. Two clinical examples have been added to raise practical suggestions in neurovascular practice. Ischemic stroke sites determining quadriplegia have some main well-defined midline locations in the brainstem, involving the pyramidal pathways of both sides in a single synchronous ischemic lesion in the medulla oblongata and in the pons. Several accompanying neurological signs have been described when the ischemic lesion involves tracts and nuclei other than the pyramidal pathways, and they can be useful as localizing clues. In some cases, the typical neuroimaging appearance of the ischemic lesion on Magnetic Resonance Imaging (MRI) has been reported as being a "heart appearance sign". This last sign has been described in midbrain strokes too, but this location is not associated with quadriplegia. The main etiology is atherothrombosis involving the intradural segment of the vertebral artery (VA) and their perforating branches. Two clinical examples of these rare vascular syndromes have been chosen to support a pragmatical discussion about the management of these cases. A midline ischemic stroke in the brainstem is a very rare vascular syndrome, and the acute onset quadriplegia is a distinctive feature of it. The awareness of this cerebrovascular manifestation might help to recognize and treat these patients.

Abstract
This study was to explore the application value of magnetic resonance imaging (MRI) image reconstruction model based on complex convolutional neural network (CCNN) in the diagnosis and prognosis of cerebral infarction. Two image reconstruction methods, frequency domain reconstruction network (FDRN) and image domain reconstruction network (IDRN), were introduced based on the CCNN algorithm. In addition, they were integrated to form two new MRI image reconstruction models, namely D-FDRN and D-IDRN. The peak signal to noise ratio (PSNR) value and structural similarity index measure (SSIM) value of the image were compared and analyzed before and after the integration. The MRI images of patients with cerebral infarction in the dataset were undertaken as the data source, the average diffusion coefficient (DCavg) and apparent diffusion coefficient (ADC) values of different parts of the MRI image were measured, respectively. The correlation of the vein abnormality grading (VABG) to the infarct size and the degree of stenosis of the responsible vessel was analyzed in this study. The results showed that the PSNR and SSIM values of the MRI reconstructed image of the D-IDRN algorithm based on the CCNN algorithm in this study were higher than those of other algorithms. There was a positive correlation between the VABG and the infarct size (r = 0.48 and P = 0.002), and there was a positive correlation between the VABG the degree of stenosis of the responsible vessel (r = 0.58 and P < 0.0001). The ADC value of the central area of the infarct on the affected side was significantly greatly lower than that of the normal side (P < 0.01), and the DCavg value of the central area of the infarct was much lower in contrast to the normal side (P < 0.05). It indicated that an image reconstruction algorithm constructed in this study could improve the quality of MRI images. The ADC value and DCavg value changed in the infarct central area could be used as the basis for the diagnosis of cerebral infarction. If the vein was abnormal, the patient suffered from severe vascular stenosis, large infarction area, and poorer prognosis.

Abstract
Objective: To investigate the clinical manifestations, magnetic resonance imaging (MRI) features, and prognosis of patients diagnosed with bilateral cerebral peduncular infarction (BCPI) with the 'Mickey Mouse ears' sign.Methods: This study, retrospectively summarized the clinical features, MRI and magnetic resonance angiography (MRA) manifestations, and prognosis of 5 patients diagnosed with BCPI and with the 'Mickey Mouse ears' sign from our hospital. In the meantime, we also systematically analyzed and summarized the clinical and imaging features, and prognosis in combination with relevant cases from the national and international literature that had been reported.Results: In our study, five cases presented tetraplegia whereas 4 cases presented disturbance of consciousness. In all cases, the 'Mickey Mouse ears' sign was observed in the mid-brain level using a diffusion-weighted imaging (DWI) cross-section. The MRA images showed thrombosis on either the basilar artery (BA), posterior cerebral artery (PCA), or superior cerebellar artery (SCA). All the studied patients received standardized treatment for cerebral infarction. However, three patients died and the remaining two were left in a locked-in syndrome state.Conclusions: BCPI is a very rare stroke disease and its main clinical manifestations are locked-in syndrome and persistent vegetative states. However, the obtained imaging features on the brain-MRI of patients diagnosed with BCPI with the 'Mickey Mouse ears' sign can predict a bad prognosis.

Abstract
Bilateral cerebral peduncular infarction (BCPI) is a very rare disorder among stroke patients. The main clinical manifestations in the previously reported BCPI case reports was associated with locked-in syndrome or persistent vegetative state. Here, we present a 51-year-old woman who had pseudobulbar palsy and quadriplegia. Magnetic resonance imaging showed an acute infarction in the middle areas of the cerebral peduncle with a unique "Mickey Mouse ears" sign. Diffusion tensor imaging and tractography showed relatively preserved corticospinal tracts, but the corticobulbar tracts were not detected. Magnetic resonance angiography showed posterior cerebral artery and vertebrobasilar artery occlusion. Cerebral perfusion insufficiency due to stenosis or occlusion of the vertebrobasilar artery and its branches may lead to BCPI. The prognosis and clinical manifestations of BCPI are related to the extent of the infarction in the involved cerebral peduncle and whether other territories are involved. Isolated BCPI may present a severe pseudobulbar palsy with relatively preserved limb function depending on the involvement pattern.

Abstract
An extremely rare case of bilateral cerebral peduncular infarctions (BCPI) is reported. The detection of the pure Mickey Mouse ears sign on MRI is an indicator of a need for reperfusion therapy. Severe stenosis of the basilar artery (BA) and a poor collateral supply from both posterior cerebral arteries were seen. Balloon angioplasty for the BA stenosis ameliorated the stenosis and produced a favorable outcome.

Abstract
OBJECTIVE The aim of this study was to characterize clinical features, etiologies, and mechanisms of strokes due to bilateral middle cerebellar peduncle infarction (BMCPI). METHODS Cases diagnosed as BMCPI in our hospital were retrieved, and a literature review was performed. Data on clinical features and brain MRI were obtained. Extracranial and intracranial segments of the vertebrobasilar artery were assessed by using digital subtraction angiography, magnetic resonance angiography, or computed tomography angiography. RESULTS Thirteen cases (11 men and 2 women) of BMCPI were identified. A high-intensity signal of diffusion-weighted imaging sequence involving the bilateral middle cerebellar peduncle was observed in all patients. Most patients experienced vertigo, dysarthria, ataxia, and hearing disorders. Eleven of these cases were classified as large artery atherosclerosis, one as traumatic vertebral artery (VA) dissection, and one as giant cell arteritis. CONCLUSION BMCPI is a rare cerebrovascular disease characterized by vertigo, ataxia, and dysarthria, which may also be accompanied by a hearing deficit or clinical signs of brainstem damage. BMCPI may be associated with hypoperfusion secondary to occlusive disease of the bilateral VA or proximal basilar artery.

Abstract
RATIONALE Due to the rarity of bilateral cerebral peduncular infarction (BCPI), its symptoms and prognosis are not clear. It is necessary to collect cases of pure cerebral peduncular infarction, explore the etiology and anatomy of midbrain infarction in depth, and develop meaningful tools for explaining clinical symptoms and predicting prognosis of patients. PATIENT CONCERNS We here provide a case of isolated BCPI with uncommon symptoms of ataxia, dysarthria, sensory disturbance, normal muscular strength, and full eye movements. DIAGNOSES Diffusion weighted images and apparent diffusion coefficient map of our patient revealed acute and isolated bilateral peduncle cerebrum infarction. INTERVENTIONS Drugs that could improve circulation and antiplatelet were used in therapy. OUTCOMES The infarct size was enlarged and new infarction was identified in the splenium of the corpus callosum and pons. The patient developed progressed disorder of consciousness and died at the eleventh day. LESSONS We inferred that the symptoms of ataxia, dysarthria, sensory disturbance, and mild paresis of the extremities could be prominent features of patients with pure cerebral peduncular infarction. We hypothesize that pure BCPI is also related to severe basilar artery stenosis or occlusion and there is no collateral circulation from PCA. This may explain the corresponding distribution of cerebral peduncular infarction and its poor prognosis. For these reasons, exploring etiology and anatomy of midbrain infarction in depth would have clinical value for predicting symptoms and prognosis.

Abstract
Objective: To investigate the anatomical characteristics, clinical manifestations, and imaging features of bilateral cerebral peduncular infarction. Methods: A retrospective analysis was performed on 11 patients diagnosed with bilateral cerebral peduncular infarction in the Affiliated Hospital of Xuzhou Medical University from December 2014 to December 2018. Their clinical and imaging features were analyzed and summarized in combination with the relevant national and international literature. Results: Among all the patients, there were eight cases with a history of hypertension, four cases with a history of diabetes mellitus, and four cases with a history of smoking. Conscious disturbance was observed in nine cases, quadriplegia in seven cases, pseudobulbar paralysis in three cases, and ataxia in one case. Brain magnetic resonance (MR) scans of bilateral cerebral peduncles showed patchy abnormal shadows with a hypointense signal on T1-weighted imaging (T1WI) and apparent diffusion coefficient (ADC) and hyperintense signal on T2-weighted imaging (T2WI), fluid-attenuated inversion recovery (FLAIR), and diffusion-weighted imaging (DWI). Computed tomography angiography (CTA) scans of head and neck showed severe stenosis or occlusion of vertebral artery, basilar artery, or posterior cerebral artery. All the patients received standardized treatment for cerebral infarction. Six patients died while five were left disabled. Conclusion: Bilateral cerebral peduncle infarction may be related to cerebral perfusion insufficiency caused by the stenosis or occlusion of vertebrobasilar artery and its branches. The main clinical manifestations are locked-in syndrome and persistent vegetative state. The specific imaging feature of "Mickey Mouse ear"-like infarction is associated with a poor prognosis.

Abstract
Isolated bilateral cerebral peduncular infarctions (BCPI) presenting as acute pseudobulbar palsy are rarely reported and, to the best of our knowledge, most of the previous reports of BCPI were related to locked-in syndrome and disturbance of consciousness. Herein, we described a case of a 55-year-old man who presented with acute pseudobulbar palsy and mild tetraparesis, but preserved eye movements, with no consciousness disturbance. DWI revealed an acute infarction involving the central portion of the cerebral peduncle with a characteristic “traditional Chinese eight character” sign. The relationship between the infarcted range in the cerebral peduncle and the clinical manifestation was discussed in our report.

Abstract
MicroRNAs (miRNAs) regulate biogenesis and disease development by targeting numerous mRNAs. miRNA (miR)‑124 and its direct target, inhibitor of apoptosis‑stimulating protein of p53 (iASPP), may be involved in tumor development and progression. The aim of the present study was to explore the role of miR‑124‑targeted iASPP in glioma. The results demonstrated that miR‑124 was aberrantly expressed in astrocytic glioma tissue and in the human glioblastoma cell lines U87 and U251. The expression of miR‑124 was lower in astrocytic gliomas compared with normal brain (NB) tissues, with a more reduced expression in higher‑grade tumors. In addition, several miR‑124 loci (including miR‑124‑1, miR‑124‑2 and miR‑124‑3) were revealed to be more highly methylated in U87 cells compared with methylation levels in U251 cells and NB cells. Furthermore, the expression of iASPP was higher in high‑grade astrocytic gliomas compared with low‑grade astrocytic gliomas. miR‑124 overexpression effectively inhibited U87 and U251 cell migration. In addition, miR‑124 regulated cell viability and arrested the cell cycle at the G0/G1 phase in these two cell lines. miR‑124 also reduced the expression levels of the cell cycle related genes iASPP, cyclin‑dependent kinase (CDK)4, CDK6 and cyclin D1. Results from the present study indicated that expression of the miR‑124 target gene iASPP may contribute to glioma development and progression.
