复方麝香注射液联合脑血肿引流术治疗中老年高血压脑出血疗效观察及费用对比

目的:探讨复方麝香注射液联合微创手术治疗中老年高血压脑出血的临床疗效.方法:将78例接受微创治疗的患者随机分组,两组均采用内科综合治疗.手术对照组在综合治疗基础上加用微创手术进行脑血肿引流;中西医结合组在微创手术治疗后加用复方麝香注射液(10～20 ml/d)静脉滴注1周.结果:中西医结合组显效率(66.67%)、有效率(82.05%)均明显高于手术对照组(46.15%和69.23%,P均<0.05),存活患者日常生活能力也明显优于手术对照组(P<0.05),意识恢复时间明显短于手术对照组(P<0.05),并发症的发生率(15.38%)明显低于手术对照组(38.46%,P<0.01),病死率(5.13%)明显低于手术对照组(10.26%,P<0.01),平均住院天数[(18.29±4.93)d]明显少于手术对照组[(26.23±5.82)d,P<0.05],平均住院费用[(5 916.23±826.39)元]明显少于手术对照组[(8 168.35±1 021.21)元,P<0.05].结论:脑血肿引流术后加用复方麝香注射液治疗中老年高血压脑出血,可降低病死率,减少并发症,降低病残程度,提高生存患者的生活质量,缩短住院时间,降低治疗费用.     

二氮嗪对大鼠脑缺血再灌注细胞凋亡的影响

目的研究二氮嗪开放线粒体ATP敏感性钾通道对大鼠脑缺血再灌注细胞凋亡的影响。方法采用线栓法建立大鼠局灶性脑缺血再灌注损伤模型,将20只大鼠随机分成4组,假手术组、缺血组、缺血＋二氮嗪治疗组和缺血＋二氮嚷＋MitoK（ATP）通道特异性抑制剂5-HD组。观察各组凋亡细胞数和凋亡相关蛋白Bcl-2、Bax的变化。结果与缺血组比较,二氮嗪使凋亡细胞数明显减少（83．2±9．04 vs 123．96±13．45）,Bcl-2表达增高（0．17±0．01 vs 0．13±0．01）,Bax表达下降（0．15±0．02 vs 0．20±0．03）,差异具有显著性（P＜0．05）。5-HD能取消这些作用（P＜0．05）。结论局灶性脑缺血再灌注损伤时,二氮嗪能通过上调半暗带区Bcl-2蛋白表达,下调Bax蛋白表达,减少神经元凋亡,对脑缺血损伤起保护作用。

法莫替丁与H1受体拮抗剂联合治疗慢性荨麻疹124例疗效观察

124例单用H1受体拮抗剂治疗疗效差的慢性荨麻疹患，联合应用法莫替丁治疗4周，结果显示临床痊愈率和显效分别为85．4％和10．5％，表明法莫替丁与H1受体拮抗剂联合用于这类H1受体拮抗剂不能奏效的慢性荨麻疹患是一种有效的治疗方法。     

手术前心理护理及层次需要

需要是人为了生活所必须的事物在头脑中的反映，是人类行为的动力，个性积极性的源泉。根据人们在生活选择中，因其不同的时期不同动机的追求目的所产生的动力也不尽相同，提出了需要层次不同学说，即生理、安全、尊敬、相互相爱和自我实现五个层次。术前这一短暂而特定的时期，病人仍然存在需要层次的问题，发现病人具有与健康人共同的     

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.
