人血浆高敏感性C反应蛋白与代谢综合征相关性分析

目的:了解我国人群血浆高敏感性C反应蛋白(hs-CRP)水平与代谢综合征(MS)关系及其它影响hs-CRP水平的相关因素。方法:1198例血浆标本来自2006年3月~2006年11月在浙江省桐乡市第三人民医院体检人群。采用Beckm an LX20血生化全自动生化仪及其配套试剂,测定上述空腹血浆标本中血糖(FPG)、甘油三脂(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-c)、低密度脂蛋白胆固醇(LDL-c)和hs-CRP水平。MS诊断标准参照中华医学会推荐标准。采用SPSS13.0统计学软件,分析hs-CRP水平与MS关系及其它影响hs-CRP水平的相关因素。结果:男性hs-CRP水平(x±s=1.55±0.53)高于女性(x±s=1.32±0.56)(P<0.001)。15.3%被检者(183/1198)患有MS,其hs-CRP水平明显高于非MS者(P<0.001)。各MS判断指标中,分别有肥胖、高血压病、糖尿病、高TG、低HDL-c时,其hs-CRP水平也明显升高(P<0.001)。排除年龄、性别影响后,hs-CRP水平与MS显著相关(OR值2.18,P<0.001)。结论:hs-CRP水平与MS密切相关,hs-CRP水平增高可作为独立反映MS发生的标志性检测指标。

大鼠胎胰胰岛组织培养及移植的实验观察

本实验对培养中的大鼠胎胰胰岛组织及其移植后的形态功能进行了观察。结果表明,大鼠胎胰经短期培养,不仅内分泌胰岛β细胞的活力保存良好,而且胰外分泌腺泡大大减少以致消失。21只糖尿病大鼠,同种移植经过7天培养的胎胰胰岛,未用免疫抑制剂,术后糖尿病缓解率76.2％。     

不同起搏模式对病人生存质量影响的调查研究

[目的]探讨不同起搏模式对病人生存质量（QOL）的影响。[方法]以健康调查问卷（SF一36量表）对112例不同起搏模式病人进行问卷调查，比较3种起搏模式下病人的QOL水平。[结果]除机体疼痛、角色情绪2个维度外其余6个维度（生理功能、角色限制、活力、社会功能、精神健康、总体健康）3种起搏模式间比较差异有统计学意义（P〈0．05）。[结论]应用AAI型、DDD型起搏器的病人生存质量优于VVI型起搏。

Biochemical and ultrastructural alterations produced by miconazole and econazole in Trypanosoma cruzi

Miconazole and econazole, two fungicide imidazole derivatives, completely inhibited growth of Trypanosoma cruzi (Tulahuen strain) at concentrations of about 20 muM. Culturing of T. cruzi in the presence of lower doses of imidazole derivatives produced: decrease of 5,7-diene sterol content in epimastigotes (including ergosterol); disappearance of the nuclear chromatin, vacuolization and decrease in the electron density of the cytoplasm; selective surface alterations as revealed by an increased response to wheat-germ- and phytohemagglutinin. At variance with the effect of miconazole on Candida (De Nollin et al. (1977) Antimicrobial. Agents Chemother. 11, 500-513), miconazole and econazole, under the experimental conditions used, did not increase the rate of hydrogen peroxide generation by T. cruzi.

Guidance of dopaminergic neuritic growth by immature astrocytes in organotypic cultures of rat fetal ventral mesencephalon.

Astrocytes, with their many functions in producing and controlling the environment in the brain, are of great interest when it comes to studying regeneration after injury and neurodegenerative diseases such as in grafting in Parkinson's disease. This study was performed to investigate astrocytic guidance of growth derived from dopaminergic neurons using organotypic cultures of rat fetal ventral mesencephalon. Primary cultures were studied at different time points starting from 3 days up to 28 days. Cultures were treated with either interleukin-1 beta (IL-1 beta), which has stimulating effects on astrocytic proliferation, or the astrocytic inhibitor cytosine arabinoside (Ara-C). Tyrosine hydroxylase (TH)-immunohistochemistry was used to visualize dopaminergic neurons, and antibodies against glial fibrillary acidic protein (GFAP) and S100 beta were used to label astrocytes. The results revealed that a robust TH-positive nerve fiber production was seen already at 3 days in vitro. These neurites had disappeared by 5 days. This early nerve fiber outgrowth was not guided by direct interactions with glial cells. Later, at 7 days in vitro, a second wave of TH-positive neuritic outgrowth was clearly observed. GFAP-positive astrocytic processes guided these neurites. TH-positive neurites arborized overlying S100 beta-positive astrocytes in an area distal to the GFAP-positive astrocytic processes. Treatment with IL-1 beta resulted in an increased area of TH-positive nerve fiber network. In cultures treated with Ara-C, neither astrocytes nor outgrowth of dopaminergic neurites were observed. In conclusion, this study shows that astrocytes play a major role in long-term dopaminergic outgrowth, both in axonal elongation and branching of neurites. The long-term nerve fiber growth is preceded by an early transient outgrowth of dopamine neurites.
