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.     

敌枯双慢性毒性实验的病理形态学研究——实验大鼠脏器组织病理变化

将150只SD大鼠随机地分成Ⅰ,Ⅱ,Ⅲ,Ⅳ四个实验组和一个对照组(Ⅴ)。实验组敌枯双剂量分别为1.0,0.2,0.05及0.01mg/kg,均用去离子水配成相应浓度的染毒水,由动物自由摄取,对照组摄入去离子水。于实验第29.5,55周分两批处死。经组织病理学检查,结果发现:敌枯双可引起甲状腺滤泡上皮细胞萎缩甚至脱屑,其发生率(Ⅲ组为63.64%)与对照组(0%)比较差异有高度显著性(P<0.01);睾丸曲细精管各级生精细胞减少、萎缩甚至完全消失,其发生率(Ⅳ组为58.33%)与对照组(8.33%)比较差异有显著性(P<0.01);对心肌、肝组织也有不同程度的损伤.     

美学在责任制护理工作中的应用

随着医学模式的转变,护理模式也由传统的功能制护理转变为责任制护理,其实质就是以护理程序为核心,以计划为内容,以责任制为特点,以评价护理实效为目标的系统护理.责任护士系8h在班,24h负责制,分管一定数量的病人,对病人有关护理问题负有全责.她们的一举一动,一言一行都会影响着整个护理计划的实施和效果,这就要求责任护士在道德、心理、性格、学识和技能等方面具有能协助医生、帮助病人战胜疾病和死亡的基本条件,责任护士在病人心目中应是“生命的守护神”，

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。     

舒利迭治疗哮喘的临床观察

目的观察舒利迭治疗支气管哮喘的疗效.方法对32例确诊为支气管哮喘的患者吸入舒利迭前后的临床疗效及实验室指标进行观察对比.临床疗效分为显效、有效及无效.实验观察指标包括淋巴细胞亚群(CD4、CD8、CD4/CD8)测定、肺功能(FEV1、PEFR)检查及支气管激发试验(PD20-FEV1).结果舒利迭治疗支气管哮喘的总有效率为81.5%,治疗后患者CD8细胞增加,CD4/CD8比例下降,FEV1、PEFR、PD20-FEV1增加,P值均<0.01.结论吸入舒利迭治疗支气管哮喘有较好的临床疗效,能增强患者的免疫功能,改善肺通气功能,降低患者的气道高反应性.
