广东Ⅰ型心脏生物瓣膜置换术后瓣膜生存分析

Zhongshan Daxue xuebao. Yixue kexue ban, 2004
【目的】探讨广东I型心脏生物瓣膜置换术后瓣膜5年及10年累计生存率及生存规律,为临床治疗工作提供依据。【方法】1978年5月-1998年12月期间随访在广东省心血管病研究所接受广东I型心脏生物瓣膜置换术病例177例(男85例,女92例,年龄7～53岁),搜集瓣膜生存时间数据等。【结果】177例病人广东Ⅰ型心脏生物瓣膜5年及10年累计生存率分别为93.2%、49.0%。男、女瓣膜累计生存率曲线间差异无统计学意义。低(≤14岁)、中(15～40岁)、高(≥41岁)3个年龄组瓣膜累计生存率曲线比较,其中低与中,

计算机图像分析应用于单颗牙齿推断个体年龄方程的研究

Zhongshan Daxue xuebao. Yixue kexue ban, 1992
应用多重逐步回归对842颗成人牙齿结构变化测量法,分级法和对数转换数据进行分析研究,从而推导出利用单颗牙齿推断年龄方程,根据适用范围和牙齿类型的不同,从实验组得到的方程推断年龄的估计标准误分别为2.4～5.6岁,各方程测试于考核组标本时,估计的标准设分别为1.9～5.4岁,提高了利用单颗牙齿推断年龄的准确性和可靠性,对数转换对提高年龄复相关系数和减少推断年龄的估计的标准误有显著意义 ...
