糖皮质激素依赖性皮炎的治疗进展

糖皮质激素依赖性皮炎临床报道中,中医、中西医结合的治疗方法最多,显示出了其优势所在,其中中药疗效优于西药,且在改善和治愈面部潮红、毛细血管扩张、色素变化、病情反跳等症状方面优势明显,对于面部痤疮样皮疹、痒及不适等症状,中、西药治疗疗效相近。目前糖皮质激素依赖性皮炎最好的治疗方法应该是中西医结合疗法。     

针法微型外科解剖学基础

1针法微型外科对解剖学的要求 随着临床医学的发展，对解剖学从不同角度、不同形式提出了要求。解剖学指导和促进了医学的发展，同时又要求解剖学不断创新。早期的解剖学主要是服务于外科手术。随着外科手术的细致深入和发展，除常规的人体解剖和局部解剖外，又出现了显微外科解剖，人体皮瓣解剖，B超、CT和核磁共振等影像学解剖。     

氯胺酮对荷包牡丹碱诱导PC12细胞内Ca2+浓度波动方式的影响

目的研究氯胺酮对荷包牡丹碱诱导PCI2细胞内Ca^2＋浓度波动方式的影响。方法使用含25ng／LNGF的DMED培养基在多聚赖氨酸包被的培养皿中培养PCl2细胞；与终浓度10gmol／L的Ca^2＋指示剂Fluo-3 AM ester共孵育30min洗涤后，加入终浓度50gmol／L荷包牡丹碱；在激光共聚焦显微镜选定多个细胞分别测定荧光强度的变化；随后加入氯胺酮，记录细胞荧光强度的改变。在试验结束前依次加入Triton X-100和EGTA分别记录单个细胞最大荧光强度（Fmax）和最小荧光强度（Fmin），以计算细胞内Ca^2＋的相对强度。结果氯胺酮不改变荷包牡丹碱诱导PCl2细胞内Ca^2＋浓度波动的基线，但抑制细胞内Ca^2＋浓度升高的幅度（P〈0．05），缩短相邻波峰间的时间间隙（P〈0．05）。结论氯胺酮不仅改变荷包牡丹碱诱导PCl2细胞内Ca^2＋浓度升高的幅度，而且改变Ca^2＋浓度波动的周期。     

Neuroprotective effect of estrogen after chronic spinal cord injury in ovariectomized rats

BACKGROUND: At present, there is still lack of effective drugs for chronic spinal cord injury, whereas it is found recently that estrogen has a neuroprotective effect on brain and spinal cord injuries. OBJECTIVE: To observe the effect of estrogen on the apoptosis of nerve cells after gradual chronic spinal cord injury in ovariectomized rats. DESIGN: A randomized controlled animal trial. SETTING: Institute of Orthopaedics, the Second Hospital of Lanzhou University. MATERIALS: Sixty-five female Wistar rats of common degree, weighing 220–250 g, were provided by the experimental animal center of Lanzhou University. The rats were randomly divided into sham-operated group (n =5), estrogen-treated group (n =30) and saline control group (n =30), and the latter two groups were observed at 1, 3, 7, 14, 28 and 60 days respectively, and 5 rats for each time point. METHODS: All the rats were treated with bilateral oophorectomy 2 weeks before the experiment. T10 vertebral lamina was revolved into using plastic screw. The spinal canal impingement was not induced initially. After that, the original incision was opened to expose the screw every 7–10 days. MAIN OUTCOME MEASURES: The apoptosis and Caspase-3 positive cells in the damaged spinal cord were detected using terminal deoxynucleotidal transferase-mediated dUTP-biotin nick end labeling (TUNEL) method and Caspase-3 immunohistochemical staining at 1, 3, 7, 14, 28 and 60 days after chronic spinal cord injury respectively. RESULTS: Totally 65 rats were used, and the deleted ones during the experiment were supplemented by others. Changes of Caspase-3 expression after spinal cord injury: In the sham-operated group, only a small amount of Caspase-3 proteins were observed in the rat spinal cord, mainly located in motor neurons of spinal cord anterior horn. In the estrogen-treated group and saline control group, positive cells expressed occasionally at 1 day postoperatively, began to increase obviously at 7 days after injury, strongly expressed at 14 and 28 days, but decreased at 60 days, mainly located in the neurons of spinal cord gray matter anterior horn, and they expressed fewer in the motor neurons and white matter of ventral horn, and there were obvious differences between the estrogen-treated group and saline control group at 7, 14, 28 and 60 days (P < 0.05). CONCLUSION: Estrogen can reduce the apoptosis of nerve cells and promote the recovery of neurological function following gradual chronic spinal cord injury.     

影响飞行员掩饰性心理家庭多因素分析

目的 探讨飞行员夫妻双方掩饰性与心理健康及婚姻质量的关系.方法 采用症状自评量表、艾森克个性问卷的掩饰分量表和Olson婚姻质量问卷对288名空军飞行员夫妻双方进行评定,采用SPSS 15.0进行相关分析、回归分析.结果 发现飞行员以及妻子的掩饰特质与自身的心理健康9个因子:躯体化、强迫症状、人际关系敏感、焦虑、抑郁、敌对、恐怖、偏执、精神病性具有显著负相关性,前者相关系数在-0.219～-0.306之间,后者在-0.127～-0.391之间.飞行员以及妻子的掩饰特质与自身婚姻质量的12因子中的6(相关系数0.151～0.232)、7(相关系数0.123～0.309)项有显著正相关性;飞行员以及妻子的掩饰特质与对方的婚姻质量各有4项存在显著相关性,前者相关系数在0.127～0.251之间,后者在0.129～0.203之间.多因素分析揭示,对丈夫掩饰特质贡献最大的因素依次为妻子的焦虑情绪、妻子的恐怖情绪、丈夫的敌对情绪、妻子的婚姻满意度、丈夫的角色平等性;对妻子掩饰特质贡献最大的因素依次为妻子的敌对情绪、经济安排、性格相客性,丈夫的性生活、与亲友关系等.结论 开展飞行员心理健康教育,进行婚姻家庭心理咨询时,提高夫妻双方的掩饰性是非常有必要的.
