RESUMEN
Objective To investigate the plastic surgery of facial soft tissue for improvement of facial contour. Methods Botulinum toxin type A was injected into hypertrophied masseter to make it atrophy and attenuation; meanwhile, buccal fat lining was partly resected by intra-oral approach. Buc-cal liposuction was performed if necessary. Results 36 cases got satisfactory face thinning results af-ter treatment. The facial contour of all patients was markedly improved. Following up for 6 - 12 months showed that the effect was stable. Conclusion Plastic repair of facial soft tissue for improve-ment of facial contour is a simple approach, with mild injury, quick recovery, safe and effective.
RESUMEN
AIM: To investigate the genes differential expression in cortex during rat focal cerebral ischemia. METHODS: cDNA microarray chips containing numerous cDNAs were used to investigate the gene expression pattern between samples of focal cerebral ischemia and sham-control operation rats. RESULTS: Two hundred and eleven genes differentially expressed were screened out, among these genes, up-and down-regulated genes were 199 and 12, respectively. CONCLUSIONS: The analysis of gene expression pattern of focal cerebral ischemia based on cDNA microarray can realize high-throughput screening of the genes associated with the focal cerebral ischemia. The differential expression of genes may be related to the pathogenesis of focal cerebral ischemic diseases.
