内窥镜辅助下经口咽前路寰枢椎减压术

目的：探讨内窥镜辅助下经口咽前路寰枢椎减压术的临床效果。方法：1998年8月～2004年8月对38例陈旧性寰枢椎脱位患者采用内窥镜辅助下经口咽前入路减压术，其中18例行一期经口咽入路减压和后路枕颈内固定术：15例行经口咽前路寰枢椎复位钢板内固定术；5例不可复型仅行经口咽前入路减压术。结果：平均随访38个月（6～96个月）。术后患者临床症状均明显改善，上颈段脊髓减压改善率达89.3％。发生颅内感染1例，前路钢板松脱1例。结论：与常规减压方法相比，内窥镜辅助下经口咽前路寰枢椎减压手术创伤小，操作精细、准确，术中与助手可协同操作。     

Head lice in Israeli children: parents' answers to an epidemiological questionnaire

BACKGROUND: The aim was to determine the influence of the socioeconomic status of the family and the hygienic practices in the home on the prevalence of head lice infestation in children. METHODS: The study was carried out by analyzing the answers to a standardized epidemiological questionnaire given to parents of school children aged 4-17 in Bet Shemesh, a medium-sized urban town 25 km from Jerusalem. RESULTS: Of 3,000 questionnaires distributed, 958 (31.9%) were completed and returned. The majority of the children (72.4%) had been previously infested with lice. Half of them had other family members, mainly brothers and sisters, who had been infested in the past with lice. In 97.5% of the families the mother was responsible for examining the children for lice, and for carrying out treatment when infestation was present. An association was found between presence of lice infestation and mother's education, age of child, and frequency of shampooing, combing, and examination for lice. There was no association between infestation rates and mother's country of origin, crowding in the home, and the sharing of combs, brushes, hats, scarves, towels, and clothes. CONCLUSIONS: There is evidence that the incidence of lice infestation depends on the hygienic practices in the home rather than on the socioeconomic status of the family or sharing of personal articles among family members.     

膳食黑米皮抑制高脂诱导的家兔动脉粥样硬化形成及其机制的初步探讨

目的 探讨膳食黑米皮对高脂诱导的家兔动脉粥样硬化形成的影响及其作用机制。方法 24只雄性新西兰大耳白家兔,按体重随机分为3组,分别饲以正常基础饲料、高脂饲料(含96％基础饲料、0.5％胆固醇、3.5％猪油)、黑米皮饲料(含 91％基础饲料、0.5％胆固醇、3.5％猪油、5％黑米皮),实验期为 60d。用图像分析法测定各组家兔主动脉脂质斑块面积,并分析家兔氧化与抗氧化状态。结果 黑米皮实验家兔的主动脉壁斑块面积较高脂组低66%(P<0.001);黑米皮组实验家兔的主动脉壁8-ohdG含量和血清及主动脉壁中MDA水平也低于高脂组(P<0.05 );而红细胞及主动脉壁中SOD水平和血清α-生育酚含量在两个处理组之间差异无显著性。结论 膳食黑米皮可以抑制高脂诱导的家兔动脉粥样硬化形成,其机制可能与之降低机体氧化应激水平及过氧化脂质生成有关。     

Regulation of NGF gene expression in CNS glia by cell-cell contact.

Nerve growth factor (NGF) gene expression in central nervous system (CNS) glia appears to be associated with active glial growth. To study the underlying molecular mechanisms, we examined the effects of a number of growth-related factors on NGF mRNA expression in glial cultures. Our results suggest that glial membrane interaction, as a consequence of growth, actively inhibits NGF gene expression in CNS glia.
