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.

髋关节撞击综合征

髋关节撞击综合征是一种常见的、可引起慢性髋关节疼痛及髋关节屈曲和内收受限的疾病,是髋关节骨性关节炎常见的病因。根据不同的解剖异常可分为Cam凸轮碰撞和Pincer钳形碰撞两型。髋关节X线正位片可观察到股骨头颈之间的凹陷度不足,表现为股骨头突起部向外侧伸延、头与颈间的凹陷减少或消失。CT及MRI能发现不明显的股骨头颈交界处及髋臼的解剖异常。而显示关节盂缘病变和邻近软骨病变及软骨下囊性变和滑膜疝,MRI较X线平片及CT更准确。主要就髋关节撞击综合征的临床、分型及影像学表现予以综述。
