Abstract: DPOAE输入输出函数曲线可以了解耳蜗的非线性,耳蜗障碍输入输出函数曲线陡峭.由于中耳在传导声音过程中是线性的,可以假设DPOAE增长曲线在传导性聋中无改变,而耳蜗损伤发现陡峭的DPOAE输入输出函数曲线,反映了耳蜗感音功能的丧失。

Abstract: 慢性鼻鼻窦炎与鼻窦CT检查之间的关系仍存在争议。1997年慢性鼻鼻窦炎的定义仅包含鼻部症状与体征，而未将影像学表现作为诊断的一部分。然而，在临床实践中，许多医生通过CT检查诊断慢性鼻窦炎，其主要目的有：①作为一项诊断性检查，证实慢性鼻窦炎的存在；②判断疾病严重程度的一种指标。作为辅助临床手术的一种手段，

Abstract: The term "protein transduction domain" (PTD) is typically used to refer to a class of small (20 amino acid) cationic peptides that can transport large, biologically-active molecules into a population of mammalian cells, which serves as a useful tool in the study on protein functions. They are also of great value in the treatment of a variety of diseases, such as ischemia, neoplasm etc., when linked to therapeutical biologically-active molecules (such as polypeptides or proteins).

Abstract: Consulting a large number of documents, we analysed the urban climate and the environmental characteristics that produced the heat island effects. The heat island effects infavor mankind health in some aspects but not in others. But generally speaking, the disadvantages are greater than the advantages, so we propose some measures and suggestions slowing down the heat island effects.
