桡骨头切除对肘关节稳定性影响的生物力学研究

目的：探讨桡骨头粉碎性骨折不同治疗方法对肘关节稳定性的影响。方法：将10个尸体标本，分别测定在其它组织无损伤时，肘内侧副韧带切断时，肘内侧副韧带和前臂骨间膜均切断时的力－位移曲线（纵向位移）及肘外翻角。结果：肘内侧副韧带切断时的纵向位移及肘外翻角均大于其它组织无损伤时；肘内侧副韧带和前臂骨间膜均切断时的纵向位移及肘外翻角均大于其它组织无损伤时和肘内侧副韧带切断时，两两间比较均有显著性差异（P＜0．001）。结论：在其它组织无损伤时，单纯桡骨头切除是安全的；合并肘内侧副韧带损伤时，可在有效修补韧带的同时作单纯头切除，必要时行假体置换；合并肘内侧副韧带和前臂骨间膜均损伤时，最好作假体置换。

免疫性血小板减少性紫癜辨证分型与血小板表面相关抗体及T淋巴细胞亚群的关系

为探讨免疫性血小板减少性紫癜（ITP）中医辨证分型与免疫机理的关系,将ITP患者中医辨证分型结合血小板相关抗体（PAIg）及T淋巴细胞亚群进行分析。发现作为本病主要抗体的PAIgG脾肾阴亏型明显高于脾虚失统型（P<0.01）;OKT₈⁺值亦显著高于脾虚失统型（P<0.05）,OKT₄⁺/OKT₈⁺比值则明显低于脾虚失统型（P<0.05）。提示脾肾阴亏型的免疫损伤程度较脾虚失统型严重。     

Potassium and sodium ions in the nerve tissue of emotionally overstrained rabbits

Measurement of K⁺ and Na⁺ concentrations in samples of individual brain nuclei and in ganglia of the autonomic nervous system from rabbits subjected to severe emotional stress (ES) through aperiodic stimulation of ventromedial hypothalamic nuclei and electrocutaneous stimulation revealed significantly altered levels of these ions in locus ceruleus samples from animals predisposed to ES-induced cardiovascular disorders and in samples of neurons of the caudal part of the brainstem from those resistant to such disorders.

目的 探讨外伤性十二指肠损伤的处理及影响预后的因素。方法 对1992年1月至2002年月1月收治的32例外伤性十二指肠损伤病例的临床资料进行回顾性分析。结果 术前确诊19例(59．4％)，漏诊13例(40．6％)；治愈29例(90．6％)，死亡3例(9．4％)；发生并发症9例(28．1％)。十二指肠瘘是主要的并发症。结论 简单而合理的手术方式是治疗十二指肠损伤的重要措施。早期手术，有效的十二指肠减压和术后肠外营养是影响预后的主要因素。     

A critical assessment of allergen component-based in vitro diagnosis in cherry allergy across Europe

BACKGROUND: Food allergy to cherry occurs throughout Europe, typically with restricted oral reactions in the central and northern parts but with frequent systemic reactions in the Mediterranean region. Previous studies have demonstrated insufficient sensitivity of commercially available cherry extract reagents in the diagnosis of cherry allergy. OBJECTIVE: To assess the diagnostic performance of specific IgE tests based on recombinant cherry allergens in comparison with an extract-based assay and to skin prick test (SPT). A secondary objective was to analyse the frequency of systemic reactions in cherry-allergic subjects across Europe, including the largest population of LTP-sensitized subjects from central Europe studied to date. METHODS: A total of 186 subjects from central Europe and Spain were studied. Serum IgE was analysed with ImmunoCAP tests carrying rPru av 1, 3 and 4, combined and separately, and cherry extract. RESULTS: Among the central European cherry allergics, the mix of rPru av 1, 3 and 4 had a sensitivity of 95%, compared with 65% for cherry extract, and the IgE binding capacity of the recombinant mix was considerably higher. The sensitivity of the two tests was more comparable in the Spanish population, 95% and 86%, respectively. The recombinant allergen ImmunoCAP equalled SPT in terms of sensitivity and specificity. Consistent with previous reports, major geographic differences in sensitization pattern and prevalence of systemic reactions were found. A significantly higher rate of systemic reactions was found in Spanish patients sensitized to Pru av 3 whereas German patients sensitized to LTP only had oral allergy syndrome. CONCLUSIONS: The recombinant cherry allergen ImmunoCAP is a highly sensitive diagnostic tool, clearly superior to any diagnostic method based on cherry extract. Three cherry allergens are sufficient for detecting sensitization in 95% of cherry-allergic subjects. Systemic reactions are common in LTP-sensitized individuals but seem to require at least one additional causative factor.

Effects of exercise on neurogenesis in the dentate gyrus and ability of learning and memory after hippocampus lesion in adult rats

Objective To explore the effects of exercise on dentate gyrus (DG) neurogenesis and the ability of learning and memory in hippocampus-lesioned adult rats. Methods Hippocampus lesion was produced by intrahippocampal microinjection of kainic acid (KA). Bromodeoxyuridine (BrdU) was used to label dividing cells. Y maze test was used to evaluate the ability of learning and memory. Exercise was conducted in the form of forced running in a motor-driven running wheel. The speed of wheel revolution was regulated at 3 kinds of intensity: lightly running, moderately running, or heavily running. Results Hippocampus lesion could increase the number of BrdU-labeled DG cells, moderately running after lesion could further enhance the number of BrdU-labeled cells and decrease the error number (EN) in Y maze test, while neither lightly running, nor heavily running had such effects. There was a negative correlation between the number of DG BrdU-labeled cells and the EN in the Y maze test after running. Conclusion Moderate exercise could enhance the DG neurogenesis and ameliorate the ability of learning and memory in hippocampus-lesioned rats.     

精神科儿少住院患者的42年资料回顾

目的了解从1958年8月本院正式成立儿童精神科以来,42年中儿童住院病人的情况,以掌握及了解儿童和少年精神障碍的发展趋势。方法从1958年8月到2000年9月之间住院的所有病人的病历共1327份,逐一记载所需资料内容,并将所有资料进行分析。结果患儿年龄主要集中在13—14岁,并涉及3—16岁各年龄段。以儿童和少年期最多,文化程度以初中和小学居多。在早期,精神障碍诊断不规范,90年代后,诊断趋于标准化,位于前五位的诊断是：精神分裂症、精神发育迟滞、脑器质性精神障碍、情感性精神障碍、行为障碍。90年代以来,每年住院儿童病人数量均呈增长趋势。结论在住院期间,儿童少年病人既要接受治疗,又需进行儿童间交友训练,而在成人精神科病房,在这一点上不能满足住院患儿的需要,不利于儿童和少年的综合治疗,所以在我院开设儿童青少年病房有重要的意义。
