ricles were scraped off by a bistoury at first and then pre-served in 70% of ethanol.Hoyer's medium was used to mount the chigger mites onto glass slides and the specimens of the chigger mites on the slides were finally identified into species under a microscope.Dispersion coefficient,clumping index,cassie index and patchiness index were used to analyze the spatial patterns of Chigger Mites.[Results] The captured 302 small mammals were identified as 16 species and 13 genera in 7 families.4 550 individuals of Chigger Mites were collected from the two auricles of 302 small mammal hosts and then they were identified as 63 species and 12 genera in     

放置不锈钢宫内节育器20年的子宫内膜亚显微结构的变化

为了了解放置不锈钢宫内节育器的安全性,我们收集了8例放置不锈钢宫内节育器20年、月经正常妇女之子宫内膜,在亚显微水平观察其变化。结果指出:压迫区子宫内膜有不同程度之萎缩或变性;移行区子宫内膜有轻度变性、轻度增生、个别细胞肥大及鳞状化生,未见明显癌变;远离区则无明显病变,对内源性性激素反应比较正常,即使核内管道系统与巨大线粒体亦仍在第17、19天两侧内膜中出现。因此,认为放置不锈钢宫内节育器20年后之子宫内膜不一定会发生严重的破坏或癌变。结合临床分析,将不锈钢宫内节育器存放时间延长至20年是可以的。     

家庭教育在社区精神分裂症患者社会功能康复中作用的探讨

为探讨家庭教育对精神分裂症患者社会功能康复的有效性和可行性，对济南市区125例精神分裂症患者亲属（主要照料者）进行了为期一年的家庭教育前瞻性对照研究，结果显示：教育组社会功能的康复较教育前有非常显著的提高，与对照组相比差异有统计学意义，提示家庭教育能够改善患者的社会功能，有利于患者的社会康复．
