RESUMEN

Intracranial atherosclerotic disease (ICAD) of a major intracranial artery, including middle cerebral artery (MCA),basilar artery, is the most common causes of stroke and is associated with a high risk of recurrent stroke in China. The difficulty to treatment these high-risk disease is to identify high-risk stroke subgroups and to develop more effective treatments (aggressive medical therapy/endovascular therapy). With the benefits, including non-invasive, in vivo, and no-ionizing radiation, 3.0 Tesla high-resolution magnetic resonance imaging (HR MRI) could be used to stratify high-risk patients, monitor progression of disease, and evaluate clinical efficacy, based on MCA wall structure and plaque characteristic. HR MRI has the latency of predicting high-risk patients benefit from endovascular therapy, having a broad application prospect during psot-SAMMPRIS era. The current research on MCA stenosis using HR MRI focuses on methodoiogy, diagnosis and differential diagnosis, etiology, and lacks of clinical efficiency evaluation and prognostic analysis of ICAD treatment, especially lacks the research on in-stent restenosis, which needs further investigation.

RESUMEN

<p><b>OBJECTIVE</b>To investigate the relation of heparanase gene and angiogenesis with the progress of gastric carcinoma (GC).</p><p><b>METHODS</b>Expression of heparanase mRNA in 52 GC tissue was detected by in situ hybridization assay. Microvessel density (MVD) was examined by immunohistochemical method. MVD and heparanase mRNA expression were analysed with their relation to histological grade, invasion depth,lymph node metastasis and organ metastasis.</p><p><b>RESULTS</b>MVD was 73.2 +/- 22.8 in 25 (48.1%) tissue with positive heparanase mRNA. It was 44.8 +/- 11.9 in 27 (51.9%) tissues with negative heparanase mRNA, between which the difference was significant (P < 0.001). MVD and heparanase mRNA expression were related with lymph node metastasis and depth of serosal invasion in GC (P < 0.005).</p><p><b>CONCLUSION</b>Heparanase, being related to angiogenesis in gastric cancer, promotes growth, invasion and metastasis. Heparanase mRNA expression is an important predictor of the biological behavior of human gastric carcinoma.</p>
