Methods Obstructive sleeping apnea syndrome was operated by midline glossectomy or simple uvulopalatopharyngoplasty in 5 patients.

有研究表明，约 30 %的OSAS患者同时存在软腭平面及舌根平面气道狭窄，单纯行悬雍垂腭咽成形术是造成手术成功率下降的原因之一[1 ] 。

For example, we have conducted the sequence screening on the binding sites of the interface of Barnase/Barstar complex and found that our DGA method can not only determine which position is more conservative and more important, but also redesign the binding sites rationally. The random sequence design for α,β,α/β and α+β four folding motifs have also been practiced and revealed that there are both homology evolution and heterology evolution of protein sequences compatible the same backbone motif.

例如，通过对典型的Barnase／Barstar复合物界面研究发现，它可以确定界面结合位点的重要性和保守性，并对结合位点进行合理的序列重新设计；通过对α、β、α/β、α+β等四种折叠模式骨架的随机序列设计，发现在蛋白质进化过程中，对同一种结构模式同时存在序列的同源进化和非同源进化这两种趋势。
