2例经皮球囊椎体成形术治疗胸腰椎压缩性骨折患者的护理

对2例经皮球囊椎体成形治疗胸腰椎压缩性骨折患者进行护理，术前做好心理护理，疼痛的护理，功能锻炼的指导，完善相关检查；术后做好生命体征的观察，积极预防骨水泥外渗、肺栓塞等并发症的发生，并指导合理饮食，加强功能锻炼。结果2例术后未发生并发症，痊愈出院，治疗效果满意。     

马棒状杆菌L型的分离鉴定及致病因子的研究

马棒状杆菌是人类极为罕见的机会致病菌，多发生于细胞介导免疫受损的病人，仅有少数免疫功能正常的人发病[1]。作者在报告2例后[2]发现11例马棒状杆菌L型致病病例，但免疫功能均为正常。特对其分离菌株进行微生物学鉴定，并作致病的毒力因子研究，报告如下。材料与方法一、标本来源13例患者皆为儿童，7～12岁。入院时主要为上腹部疼痛，非喷射性呕吐，伴发热38～39C，数d后，转下腹痛且伴腹泻及暗红色水样便。粪便、血、尿普通培养未检出致病菌。血L型培养均有细菌生长。经庆大霉素、红霉素8～lod治疗，体温等症状恢复正常，血标本L型培…     

α－脂蛋白测定质量控制、标本贮存及其正常参考值

分次使用国产ＥＬＩＳＡ药盒测定血清（浆）Ｌｐ（α）浓度过程中，进行质控、标本贮存等实验，并建立Ｌｐ（α）浓度水平的正常参考值。结果：①血清Ｌｐ（α）测值平均组内变异５．１８％、组间９．８６％，实验室间标准质控变异率０．１８％；②标本存放于—２５℃３１０天或者冻融３次后Ｌｐ（α）测值均无明显改变；③Ｌｐ（α）的血清与血浆值之间高度相关（ｒ＝０．９７４，Ｐ＜０．００１，ｎ＝６０）；④血清Ｌｐ（α）浓度在本室的正常参考值为２０４．３±１２６．４ｍｇ／Ｌ，并且呈正偏态分布，经对数或平方根变量交换均可使其正态化。     

电视新闻角度的选择

从不同方面去反映同一种东西，就会发现由于角度不同，其最终结果、主题体现、效果感受都各不相同。角度的选择，就是我们从多面主体的社会生活中，透过纷繁复杂的诸多现象，去挖掘事物的本质，分析事物，提炼精华。但是，能不能准确抓住事物本质特点的最佳角度，是对一个电视新闻记的综合素质的检验。     

奥美拉唑静脉给药治疗上消化道大出血的疗效观察

本文阐述了奥美拉唑（Ｏｍｅｐｒａｚｏｌｅ）治疗急性上消化道大出血８０例与法莫替丁（Ｆａｍｏｔｉｄｉｎｅ）治疗上消化道大出血５０例比较，前者有效率明显高于后者。提示奥美拉唑治疗急性上消化道大出血效果好，无副作用，减少了手术率、死亡率，是一种有效的止血药物。

抑郁发作自杀未遂患者脑源性神经营养因子水平及其相关因素研究

Objective To investigate the possible role of brain-derived neurotrophic factor(BDNF)in the pathophysiology of attempted suicide in depressive episode patients.Methods The subjects were 23 depressive episode patients who had recently attempted suicide.24 depressive episode patients without suicide attempt.and 30 sex-age-and education matched healthy controls.The Hamihon Depression Rating Scale-24 items(HAMD24),Beck Helpless Rating Scale(BHS)and Self-rating Idea of Suicide Scale (SIOSS)was used to evaluate the severitv of symptoms.The seruln level of BDNF was detected with sandwich ELISA.Pearson correlation coefficients wag used to measure the correlations between serum BDNF and the related illness variables.Results There were significant difierences in the serum level of BDNF between patients with attempted suicide,pailents without suicide attempt and normal controls(F=21.927,P＜0.05).Post hoc analysis showed the serum BDNF levels in patients with attempted suicide [(57 ±16)ng/L]were lower than that in patients without[(75±28)ns/L;P＜0.05],and were lower in patients without suicide attempt[(75 ±28)ng/L]than that in normal controls[(111 ±39)ng/L;P＜0.01].In patients with attempted suicide,the serum BDNF was negatively correlated to the duration of depressive episode(r=-0.541,P=0.008),the mean BHS score(r=-0.494,P=0.017)and the mean SIOSSscore(r=-0.754.P=0.000).Conclusion The results suggest that the decreased serum brain-derived neurotrophic factor is related to the pathophysiology of attempted suicide in depressive episode patients.
