通瘀注射液盆腔给药法治疗外在型子宫内膜异位症的临床研究

目的　运用通瘀注射液在非直视下经输卵管盆腔给药对子宫内膜异位症 (EEMs)的治疗作用 ,探讨活血化瘀法对EEMs的作用机理及此给药法的优势。方法　将临床治疗的EEMs患者 60例随机分为治疗组 (通瘀注射液组 )和对照组 (丹那唑组 ) ,疗程各为 3个月。用药前后测定下列指标 :临床症状与体征、内分泌激素、血液流变学、癌抗原 12 5 (CA12 5)和子宫内膜抗体 (EMAb)的阳性率变化。结果　治疗组的临床症状与体征、血液粘滞度和红细胞压积、CA12 5和EMAb的阳性率均降低 ,卵泡刺激素 (FSH)、黄体生成素 (LH)、雌二醇 (E2 )和孕激素 (P)的含量均受到调节 ,与对照组相比 ,差异有显著性。而治疗组对内分泌的调节能力弱于对照组 ,但作用柔和、均衡。结论　通瘀注射液对EEMs的作用是通过清除月经时异位内膜的瘀血、水肿、改善微循环及组织供氧、调节免疫功能和内分泌紊乱而实现的 ,与丹那唑相比其副作用小、并以治本为主。盆腔给药法则可使药物直达病灶 ,见效快     

Odontoma: a clinicopathologic study of 81 cases.

BACKGROUND AND PURPOSE: Odontoma is the most common odontogenic tumor. It includes 2 types, the compound and complex odontomas. There has not been a series study of the clinical and histologic features of odontomas from Taiwan. This study evaluated the clinicopathologic features of odontoma in Taiwanese. METHODS: Cases of odontoma treated from 1998 to 2002 identified from medical records were included. The microscopic features, radiographic features, and clinical history of the patients were reviewed and analyzed. RESULTS: A total of 81 odontomas in 81 patients (36 males and 45 females) were included. There were 62 compound and 19 complex odontomas. The mean age of the patients was 18 years with the majority of odontomas occurring in the first (32%) and second decade (38%) of life. Odontomas had a marked predilection for the maxilla (70%) and for the anterior region of the jaw (83%), particularly for the anterior maxilla (62%). Sixty four (79%) of the 81 odontomas were associated with 80 impacted teeth, including 71 permanent teeth, 2 deciduous teeth, and 7 supernumerary teeth. Of the 71 impacted permanent teeth, the maxillary central incisor (27%) was most commonly affected, followed by the maxillary canine (26%) and mandibular canine (24%). Histologic examination revealed enamel matrix in 90%, dentin in 100%, cementum in 88%, pulp tissue in 96%, fibrous capsule in 93%, ghost cells in 83%, reduced enamel epithelium in 86%, and nests of odontogenic epithelium in 58% of odontomas. Dentigerous cyst was associated with 9% of odontomas. CONCLUSIONS: In this series, odontomas occurred most often in the first and second decade of life. Although complex odontomas are usually found in the posterior jaw, in this Taiwanese series they were most commonly found in the anterior maxilla. Odontoma is frequently associated with an impacted tooth and occasionally with a dentigerous cyst. No recurrence of odontomas was found after surgical excision with follow-up of 1 to 15 years.     

Changes in brain gene expression shared by scrapie and Alzheimer disease.

We have isolated two recombinant cDNAs whose corresponding RNAs have an increased abundance in scrapie-infected hamster brain. DNA sequence analysis has shown that these two recombinants represent the genes for sulfated glycoprotein 2 and transferrin. The abundance of sulfated glycoprotein 2 RNA is increased in hippocampus from patients with Alzheimer disease and Pick disease, whereas transferrin RNA is not strongly modulated in these conditions. Expression of two previously identified scrapie-modulated genes, encoding glial fibrillary acidic protein and metallothionein, is also increased in both of these neurodegenerative diseases.     

输精管结扎干扰前列腺增生过程的机制探讨——精浆睾酮双氢睾酮的放射免疫测定

本文应用放射免疫测定的方法检测了13例输精管结扎后(平均15.3年,平均年龄50岁)的男性精浆双氢睾酮和睾酮的浓度,另取同年龄组男性13例作为对照。结果表明,精浆睾酮在结扎组(374.54p/ml)和正常对照组(315.64Pg/ml)中没有明显差异,而结扎组精浆中双氢睾酮(46.21pg/ml)却明显低子对照组(184.27pg/ml(p<0.01)。作者认为,输精管结扎对精浆DHT有长期影响,这可能是其对前列腺增生过程产生抑制作用的原因之一。     

慢性心力衰竭病人的临床分析

慢性心力衰竭（CHF）目前是老年人住院和死亡的主要原因，近几年研究结果显示CHF病人出现的肾功能障碍即心肾综合征发病率高，预后差，狭义的心肾综合征特指CHF引起的进行性肾功能损害，并导致肾功能不全，我们回顾性分析我院收治的100例CHF住院病人，着重探讨CHF程度与肾功能不全的发生率及其与住院的时间的关系。现将其临床分析介绍如下。
