目的　探讨布 -加氏综合征不同类型的介入放射学治疗效果。方法　 1例患者经下腔静脉造影后采用球囊成形术 ,其余 3例均造影后行球囊成形 支架置入术。结果　 1例膜型梗阻经球囊成形术后治愈 ,2例节段型梗阻患者经球囊成形术后分别置入“Z型支架 ,1例肝静脉型置入wallstent支架治愈。结论　介入放射学在诊治布 -加氏综合征方面是一种独特、有效的方法。     

小鼠原始生殖细胞源胚胎干细胞的分离培养和建系

目的 :对小鼠胚胎干细胞分离材料的获取及处理、胚胎干细胞分化抑制培养、细胞系的建立及保存所用技术进行探讨。方法 :取胎鼠生殖嵴及其周围组织 ,采用胎鼠的胚胎干细胞与其成纤维细胞共培养的方式进行。结果 :分离得到大量原始生殖细胞(PGCs)集落。多次克隆传代具有胚胎干 (ES)细胞的诸多特征 ,如有连续传代的能力 (有两组分别传至 3代和 4代 ) ,有典型鸟巢状结构 ,AKP染色阳性 ,体外分化实验具有形成类胚体的能力。结论 :从胎鼠生殖嵴中能够获得大量的ES细胞。采用的胚胎干细胞与其成纤维细胞共培养的方式进行胚胎干细胞的分离培养和建系是可行的     

支气管动脉给药治疗难治性肺结核（附10例报告）

难治性肺结核是当前结核专科医院内遇到较多且不好处理的一种肺结核，其特点是病程长，病情重．耐药率高。并发症多，疗效低，预后差，经支气管动脉给药能提高有效血浆浓度从而杀死结核菌，促进病灶愈合。我们近一年来对10例难治性肺结核在常规全身用药的基础上，用异烟肼．环丙杀星经支气管动脉给药，效果明显，现报告如下。     

Differentiation of human epidermal stem cells into fibroblasts induced by TGF-β1 in vitro

Objective To investigate the correlation between human epidermal stem cell (hESCs) and hypertrophic scar or keloid. Methods Improved collagen Ⅳ-coated adhesion methods was used to isolate and culture the epidermal stem cells after neutral protease selectively digested the dermo-epidermal junctions. After the cells were cultured and expanded in vitro, and passage 3 hESCs were induced by different concentrations of TGF-β1 (0.1, 5.0, and 10.0 ng/ml). Morphological fea-tures and identification of these cells were meseasured by HE, Masson, immunohistochemical staining on the days 3 and 7, respectively. Results After induced by TGF-β1 for 3 and 7 days, the morpholo-gy of the epidermal stem cell (hESCs) was changed into fusiform shape, similar to fibroblasts. 70 % ofthe cell which was induced by TGF-β1 were blue stained in the cytoplasm by Masson stain, which is the distinctive method for collagen, suggesting collagen appeared or increased in the cells. The collagen concentrations in supernatants of hESCs were 0.4150±0.0014, 0.3380±0. 0020, and 0.3870±0.0020, much higher than that in control group (0.0780±0.0025) and normal skin fibro-blast group (0.15004±0.0051) (P<0.05). Immunohistochemical staining revealed that positive rates of these cells for anti-vimentin staining were more than (95.00±1.20)% in experiments and (5.70±0.20)% in control group. Conclusion The differentiantion of hESCs induced by TGF-β1 into fibro-blasts indicates that hESCs may play a role in the pathogenesis of hypetrophic scar and keloid.     

干槽症的细菌学研究及甲硝唑微栓预防和治疗应用

本文通过对19例拔牙后干槽症患者牙窝内容物的细菌培养和药敏试验,对引起该病的特殊细菌和病因进行了探讨。同时采用甲硝唑微栓置入383例下颌阻生第三磨牙拔牙创内,观察其预防和治疗干槽症的效果,结果表明甲硝唑微栓在预防和治疗干槽症上具有明显效果。     

78结合牙1例

患者张某，女，52岁，因左上后牙自发痛2月余来诊。此牙2年前曾诊治。2月前此牙痛复发，在当地医院诊治至今，目前仍有咬合痛，偶有自发痛，来我科要求拔除，检查：7倾侧远中处银汞充填，近中洞达根底，叩（ ），松动（-），牙龈（-），8未查及，无牙列拥挤，根尖片：7根尖透射影，8阻生，78相连，其间未见牙周膜，诊断：（1）7慢性根尖周炎；（2）78为结合牙（8阻生）。     

湘西土家族、苗族、侗族癫痫流行病学调查

湘西土家族、苗族、侗族癫痫流行病学调查王华，雷花香，黄定梅，邓朝晖多年来，虽然癫痫的流行病学研究较多，但有关土家族、苗族、侗族的癫痫调查资料却极少。作者于１９９２年３月～７月对居住在湘西的这三个民族的人群进行了癫痫的流行病学调查。现将有关资料报告如下...
