| 1 | Gene expression profiles in intracranial aneurysms显示文摘In this study, we extracted total RNA from 15 intracranial aneurysms and 17 superficial temporal artery samples, then performed genome-wide expression profiling using the Affymetrix U133 Plus 2.0 GeneChip. Genes that were differentially expressed between intracranial aneurysms and arterial samples were identified using significance analysis for microarrays, and the expression patterns of three randomly-selected genes were verified by real-time polymerase chain reaction analysis. We identified 3 736 differentially-expressed genes out of the 47 000 assayed transcripts. A total of 179 genes showed a >10-fold change in expression between the aneurysms and the arterial samples. Genes involved in the proliferation, migration, and apoptosis of vascular muscle cells, atherosclerosis, extracellular matrix disruption, and inflammatory reactions were associated with the formation of intracranial aneurysms. There were no significant differences in gene expression profile between unruptured and ruptured aneurysms. | Lanbing Yu Jinghan Fan Shuo Wang Dong Zhang Rong Wang Yuanli Zhao Jizong Zhao | 2014 | Neuroscience Bulletin2014，30，1： | 3 |
| 2 | Relationships between hemorrhage, angioarchitectural factors and collagen of arteriovenous malformations显示文摘Objective While associations between the angioarchitecture of arteriovenous malformations (AVMs) in the brain and pathological features have been described, here we investigated the relationship between the angioarchitecture, the pathological features of the vessel wall, and hemorrhagic events. Methods The study was conducted on 43 patients: 16 with ruptured AVM (rAVM), 15 with non-ruptured AVM (nrAVM), 6 with craniocerebral trauma (control) and 6 with epilepsy (control). The diagnosis of AVM was confirmed by preoperative digital subtraction angiography. Tissues were stained with hematoxylin and eosin and Masson's trichrome (for collagen fibers) to evaluate the vessel wall structure and endothelial integrity. The content and distribution of collagen types I and III in the vessel wall were assessed by immunohistochemical staining. Results In the nrAVM group, the nidus had more draining veins than the rAVM group (P <0.05). Severely damaged endothelial cells, significantly fewer smooth muscle cells in the media, and hyperplasic type-I and -III collagen fibers were found in the rAVM group. The content of collagen types I and III in rAVMs was higher than that in the nrAVM (P <0.05) and control groups (P <0.01). Conclusion There is an association between angioarchitectural features such as the number of draining veins and the pathological structure of the AVM wall. These abnormalities may contribute to AVM rupture. | Hongchuan Niu Yong Cao Xuejiang Wang Xiaowei Xue Lanbing Yu Ming Yang Rong Wang | 2012 | Neuroscience Bulletin2012，28，5： | 2 |
