小儿脑胶质瘤分子遗传学研究进展

<正> 近20年来,分子遗传学的研究进展极为迅速。目前关于肿瘤的发病机理较为普遍的观点是:肿瘤是多种遗传因素的累积共同作用的结果,癌基因的活化与抑癌基因的失活是其重要因素。 原癌在细胞内的正常基因,通过扩增、突变或重排等方式转变成癌基因。癌基因编码的产物癌蛋白通过多种机制促进肿瘤生长。癌基因常为“显性”,等位基因中一个位点的突变可被激活;抑癌     

围产儿与儿童胸腺的病理改变

The most outstanding pathological changes of perinatal babies and children, based on the review of the autopsy files in the 1st Affiliated Hospital of West China University of Medical Sciences, are lymphocytic depletion, and reticuloepithelial cell swelling and/or fusiform malformation in the cortex, while in the medulla apoptosis is more prominent. We suppose that these alterations are due to immaturity of cortical thymocytes, and in the diseased condition, they are easily affected by extraordinary factors, especially the influence of corticosterone inducing acute severe necrosis, so the number of lymphocytes are obviously diminished. But, in the medulla, as intact mature lymphocytes exist, physiological phenomenon such as apoptosis is rather prominent in it. While in the medulla, Hassall's corpuscles have various characteristic changes, such as cornification, calcification, fusion, cystic change and disintegration. Besides, we observed a new alteration in the thymus defined as vacuolization. All the above pathological changes reached the peak in the 28- day group; there after, they might become either worse or better according to the condition of the disease and growth of the body. However, these are still problems to be further studied separately.     

患结节性多动脉炎的婴儿表现有低钠性高血压综合征

高血压合并低血钠性脱水被称作低钠性高血压综合征(H H S),是一种罕见且严重的高血压并发症。在此,作者报道1例17月龄的女童,其有严重的低血钠性脱水、低血钾、多尿和肾性蛋白尿,同时有恶性高血压和全身性炎性疾病。典型结节性多动脉炎的诊断多是基于肾动脉造影时显示有小动脉瘤及非动脉瘤样改变如动脉中断、动脉狭窄以及肾图灌注缺损而确定。抗高血压药物治疗引起血压下降,使得H H S患者异常得到恢复。但是,4个月的免疫抑制治疗后,结节性多动脉炎被有效控制。结论:这种罕见的系统性结节性多动脉炎在年龄非常小的儿童身上发生,是主要的价…     

351例股骨颈骨折的远期疗效

关于股骨颈骨折报道众多,治疗方案各异。基于股骨颈骨折与老龄化成比例的增加,目前它不仅是医疗问题,也成为了社会问题。Ljubljana大学创伤外科医院于1986年～1987年两年间收治了824例股骨上端骨折患者,其中股骨颈骨折351例。     

Effect of water restrictions on the physiological parameters,psychological behavior and brain c-Fos expression in rat

1 Introduction Exposure to hostile stressors causes a series of coor- dinated responses in the body, such as alterations of neu- roendocrine secretion, immune reaction and behavioral manifestation to maintain homeostasis stability and sur-vival of the organisms. Stressors are divided into two main categories: physical, or systemic, and psychological, or emotional / processive. Each stressor might activate a spe- cific central pathway to induce a special neuroendocrine response, even cause stre…     

肉芽肿性胃炎

胃的肉芽肿性炎不常见 ,播散性结节病、过敏性肉芽肿病、Crohn病、某些感染性疾病或异物反应均可导致。有时其形成缺乏以上任何因素 ,称之为孤立性 /特发性肉芽肿性胃炎。西方国家胃黏膜活检中的肉芽肿多与Crohn病有关。作者报道了 18例肉芽肿性胃炎 (占胃活检标本的 0 0 8% ) ,女性 12例 ,男性 6例 ,年龄 2 4～ 85岁 (平均 4 5 8岁 )。所有患者均有胃肠道症状 ,如上腹不适、疼痛、恶心和呕吐。患者的临床病理诊断分别为 :伴 /不伴有幽门螺杆菌 (helicobacterpylori,HP)感染的慢性胃炎 14 / 1例 ;伴有HP感染的胃腺瘤/癌 2例 ;Crohn病 1…
