简介：目的：通过临床病例探讨和研究上睑退缩的分度,及选择不同的手术方案,并观察手术治疗效果,以便对不同患者提供更加有效的治疗方案。方法：回顾性总结2000-11/2010-12上睑退缩患者98例146眼,对其病情程度进行分度及根据其分度选择不同的手术治疗,观察其手术疗效。结果：针对不同分度选择适宜的手术方法,可以有效矫正眼睑退缩。结论：眼睑退缩由于病因及眼睑退缩的程度进行分度,对不同类型患者实施个性化手术,规范眼睑退缩临床治疗路径,填补国内同种疾病的诊断和治疗方法的空白。

简介：目的为建立耳蜗Corti器及椭圆囊体外培养实验模型。方法离休Corti器及椭圆囊组织分别在DMEM+胰岛素+20%胎牛血清+葡萄糖培养基中培养9天和Medium-199+10%胎牛血清培养基中培养20天,并与同期体内发育结果比较。结果培养组织生长良好,组织结构及细胞形态均得到较好保存,其细胞分化程度与体内同期类似,无退化现象。结论该方法不仅能使组织结构及细胞形态得到保存,而且保留了细胞的活性,为耳毒性药物的作用及机制、毛细胞再生研究提供了有实用价值的实验模型。

简介：目的：观察4种上睑下垂术式的临床效果。方法：为探讨上睑下垂术的有效治疗方法，不断改进手术方式。结果：每种手术均有其优点及并发症，提上睑肌折叠术为目前较为理想的手术方法。结论：临床实践提上睑肌折叠术与以往专家理论：提上睑肌节制韧带上每缩短3～5mm肌肤，可矫正下垂量1mm不同：在节制韧带上缘折叠提上睑肌腱膜即可提起上睑，且上睑缘正好在角膜缘上2mm，术后恢复在角膜缘处。
