脑电监测（24小时）对头痛型癫痫的诊断意义

对６０例临床疑为头痛型痛痫的患者进行２４ｈ脑电监测。结果表明：２４ｈ脑电监测对痛痫特殊类型的检出率明显高于常规ＥＥＧ。在１４例（２３．３％）有痫样放电的患者中，出现痫样放电以睡眠期多于清醒期；且睡眠周期中以ＮＲＥＭⅠ，Ⅱ期最常见。对６例（１６．２％）反复阵发出现高波幅额中线θ节律而无痫性放电的患者亦应考虑头痛型癫痫的诊断。     

Guillain-Barré syndrome in South-West Stockholm, 1973–1991, 3. Clinicoepidemiological subgroups

Using hierarchical cluster analysis, applied to 47 cases of Guillain-Barre Syndrome (GBS) incident in South-West Stockholm (SWS) during the period from January 1973 to June 1992, we identified three major clinicoepidemiological subgroups. The first subgroup, 25.5% of the cases (26.7 ± 6.7 years), recorded a peak incidence at ages 20–29 years and presented significant differences from other subgroups, a high proportion of cases with onset at low age preceded by respiratory infection (83.3%) and with normal motor conduction velocity (50.0%). Also found, were less affected biological parameters, a rapidly progressive course and independence in gait at one month after onset. A second subgroup, 27.7% of cases, was severely affected, clinically and functionally. It consisted predominantly of young individuals (22.7 ± 11.1 years), with a high incidence (69.2% of cases) in autumn. A third subgroup, comprising 40.47; of cases, was older (61.1 ± 11.0 years) and, in general, also severely affected. The incidence of this form appeared to be invariant with time.     

罂粟碱对大鼠单胺神经递质的影响

本文报道用高效液相色谱-电化学检测器方法,研究了罂粟碱对大鼠脑内及心脏单胺神经递质代谢的影响。结果表明:罂粟碱能显著增加大鼠纹状体及边缘区多巴胺代谢物二羟苯乙酸(DOPAC)和高香草酸(HVA),升高约50-70%。5-羟色胺代谢物5-羟吲哚醋酸(5HIAA)增加约30%,而对脑及心脏内的单胺递质本身含量未见有明显影响。     

Hypoxia effects on vascular endothelial growth factor derived epithelial cells of nasal polyps]

OBJECTIVE: To understand the role of nasal mucous epithelial cells to hypoxia in early stage of nasal polyps(NP) formation. METHODS: Epithelial cells of NP and inferior turbinate (IT) were cultured without serum under normal oxygen and hypoxia, and stimulus of inflammatory cytokines. Erythropoietin (EPO) was regarded as hypoxia mark, and expression of vascular endothelial growth factor(VEGF) mRNA and protein derived from epithelial cells were detected respectively by in situ hybridization and ELISA. RESULTS: 1. Under hypoxia, EPO mRNA was expressed intensely in epithelial cells from NP and IT, and there was no significant difference between both of them. This result suggested that EPO might be regarded as a hypoxic mark. 2. The ability of producing VEGF mRNA increased with cytokines stimulation, especially under hypoxia. Protein level of VEGF from epithelial cells of NP and IT increased with cytokines stimulation, especially in hypoxia and was time-dependent. CONCLUSION: Epithelial cells actively produce vast VEGF under hypoxia. The VEGF induced by hypoxia of the mucosa in middle meatus is of importance in the formation of nasal polyps(NP) in early stage, which may be the major cause of NP formation in middle meatus.
