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。     

闭合性腹部损伤157例诊断和治疗体会

闭合性腹部损伤是外科常见急、重、危病人,由于腹腔内脏器多,加之致伤因素复杂,病情严重,给诊治带来一定难度。如处理不当常造成严重后果,甚至危及生命,特别腹部实质性脏器破裂,发病时间短,出血量大,来势凶,早期出现休克,若得不到有效、及时的诊断和治疗死亡率高。提高腹部创伤的救治能力,降低其死亡率,提高治愈率,减少并发症,具有十分重要的意义。回顾本院1997年至2002年对157例闭合性腹部损伤的诊断、治疗体会,现报告如下。1临床资料本院从1997年至2002年共收治闭合性腹部损伤病人157例。其中车祸76例,高处跌落伤40例,撞伤7例,刀刺伤5例,…     

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.
