The operating corneoloscope and Terry operative keratometer were used respectively in 29 and 34 eyes during the intraocular lens implantation to measure the corneal astigmatism qualitatively or quantitatively,so that the tension of incision closure could be adjusted. The surgically induced astigmatism in qualitative group two weeks after the operation was 3. 5 ± 1. 70 D and that in quantitative group was 2. 56±1. 60 D. There were 55.17% and 38. 24% of the eyes with over 2. 00 D corneal astigmatism in qu...

OBJECTIVE To investigate the clinical and pathological characteristics, diagnosis and treatment of stromal sarcoma of the breast （SSB）. Methods： The clinical and pathological data of 6 patients with SSB treated between 1954 and 2007 were retrospectively analyzed. METHODS The clinical and pathological data of 6 patients with SSB treated between 1954 and 2007 were retrospectively analyzed. RESULTS All patients were female and one was menopausal. The median age of the patients was 39 years old （range, 20-55）. All cases had a history of a palpable mass. The tumor rapidly augmented in a short time period in 3 patients. One patient had discontinuous pain and 3 patients had masses located in the upper outer quadrant of the breast. The median tumor radius was 6.0 cm （range, 3-15 cm）. According to the AJCC breast cancer staging standard （6th edition）, 1 case was of stage ⅡA, 2 cases were of stage ⅡB, 2 cases were of stage ⅢB and one case couldn＇t be staged. Four patients were initially treated by excising the tumor and then undergoing mastectomy or modified radical mastectomy after recurrence. Radical mastectomy was suitable for those with pectoralis major muscle involvement. Two patients received simple mastectom）~ 2 patients underwent radical mastectomy and another 2 patients received modified radical mastectomy. After surgery, all patients were identified as SSB through pathology, with focal ossification in one case and mucinous degeneration in another one case. Four patients who underwent axillary lymph node dissection did not have lymph node metastases. Three patients received chemotherapy after surgery. After a median follow-up time of 36.5 months （8-204 months）, 4 patients had recurrence after local excision and 3 patients had recurrence more than 2 times with a median time to recurrence of 2.5 months （1 to 4 months） after surgery. One patient had lung metastases at 7 months after the initial surgery and the other 5 patients were alive without disease at the end o

民俗早在远古时期就已与图像结缘。早期的岩画、陶器、青铜器、墓葬壁画、帛画等都包含有生产劳动、日常生活、神话传说、精神信仰的内容。魏晋以降,以社会生活为描绘对象的风俗画成为中国美术的重要分支。丰富的图像类民俗资料越来越多地引起了学界的关注。和文本研究一样,民俗学的图像研究也需从资料的搜集、归类和量化统计开始,并对民俗入画的过程进行追踪,首先解决哪些人在什么时代背景下、应何种需求、为谁画和如何画的问题。其次围绕特定的民俗主题,细读画作“文本”,考察画工选取哪些民俗要素入画并分析其原因,包括其在表现手法上所沿用的套式,并在此基础上建构图像民俗志的理论。透过图像,我们不仅可以了解一些历史民俗事象的具体面貌与细节,而且可以通过阐释图中蕴含的符号意义理解民众的思维逻辑。即便是那些因主客观原因而偏离了真实性的画作,也能折射出特定历史时期特定人群的生活理想、精神追求和审美情趣。

目的分析不同品种菜豆植物凝集素对小鼠骨髓细胞微核发生率的影响,明确其生物安全性。方法小鼠腹腔注射3个品种菜豆凝集素,6 d后取小鼠骨髓细胞,吉姆萨染色,光学显微镜下观察小鼠骨髓细胞的微核发生情况并进行微核发生率的统计,进而判断不同种类菜豆植物凝集素是否具有致突变作用。结果实验组3个品种的菜豆植物凝集素引起的小鼠微核发生率与阴性对照组比较差异均无统计学意义,而阳性对照组与实验组及阴性对照组间差异有统计学意义(P<0.05);小鼠骨髓细胞微核发生率与菜豆植物凝集素呈剂量—反应关系,但与小鼠性别无关。结论 3个含量分别为高、中、低水平的菜豆植物凝集素对小鼠骨髓细胞均无致突变作用,可进一步用于有关药物和生物制剂的开发应用。
