Introduction
Cytokines increased the risk of venous thromboembolism (VTE) in some case-control studies, but not in a prospective study. Data concerning the role of cytokines in the risk of VTE are limited. We examined in a case-control study the association of VTE and levels of interleukin (IL)-6, IL-8 and monocyte chemotactic protein-1 (MCP-1) and assessed whether promoter polymorphisms (IL-6 -174GC, IL-8 -251AT, MCP-1 -2518AG) would affect the thrombotic risk and cytokine levels.Materials and methods
The study included 119 patients (94 women) with a first event of VTE aged between 18-60 years, and 126 healthy controls (100 women) matched for age (± 5 years). Blood was collected > 7 months after the thrombotic event. Odds ratios (ORs) were calculated per increase of cytokines levels by 1 pg/mL.Results
ORs adjusted for age and sex were 1.520 [95% Confidence Interval (CI) 1.177 - 1.962] for IL-6, 1.095 (95% CI 1.002 - 1.196) for IL-8 and 1.000 (0.988 - 1.012) for MCP-1. With additional adjustment for ethnic composition, body mass index (BMI) and high sensitive C-reactive protein (hs-CRP), risk estimates remained significant for IL-6 and became of borderline statistical significance for IL-8. Polymorphisms did not influence the thrombotic risk and the cytokine levels in study participants.Conclusion
VTE was associated with IL-6 and IL-8 levels, and for IL-6 this association was independent of BMI and hs-CRP. Thus far, a causal relationship between inflammation and VTE remains to be clarified and more prospective data are warranted. 相似文献45.

Mescaline and phencyclidine (PCP) are potent hallucinogenic agents affecting human and animal behavior. As their psychotropic effects remain poorly understood, further research is necessary to characterize phenotypes they evoke in various animal models. Zebrafish (Danio rerio) are rapidly emerging as a new model organism for neuroscience research. Here, we examine the effects of mescaline (5-20mg/l) and PCP (0.5-3mg/l) in several zebrafish paradigms, including the novel tank, open field and shoaling tests. Mescaline and PCP dose-dependently increased top activity in the novel tank test, also reducing immobility and disrupting the patterning of zebrafish swimming, as assessed by ethograms. PCP, but not mescaline, evoked circling behavior in the open field test. At the highest doses tested, mescaline markedly increased, while PCP did not affect, zebrafish shoaling behavior. Finally, 20mg/l mescaline did not alter, and 3mg/l PCP elevated, whole-body cortisol levels. Overall, our studies indicate high sensitivity of zebrafish models to hallucinogenic compounds with complex behavioral and physiological effects. 相似文献

Background
Early diagnosis is crucial in management of pancreatic malignancy. DWMRI could be used in differentiating pancreatic lesions and judge about tumor aggressiveness.Patients & methods
Fifty patients were included in this prospective study with mean age ±43?years. Histopathology & follow up clinical results revealed 34 malignant and 16 benign lesions. All patients underwent non-contrast MRI examination and DWI at different b-values with ADC value measurements.Results
Conventional MRI poorly diagnosed pancreatic focal lesions with 79% Sensitivity, 68% specificity & 76% accuracy. In DWI with high b-value of 1000, 31/34 malignant lesions showed restricted diffusion with low ADC value (≤1.5?×?10?3?mm2/s) while 14/16 benign lesions showed mixed diffusion with higher ADC values (≥1.7?×?10?3?mm2/s). DWI at high b-value of 1000 with chosen ADC value of 1.5 as a cut-off value revealed high sensitivity (91.18%), 87.5% specificity, 93.84% PPV, 82.35% NPV and 90% accuracy in differentiating benign from malignant pancreatic lesions.Conclusion
DWMRI found to be a simple and non-invasive tool that aid in the diagnosis of pancreatic pathology with recommended high b-value and a cut-off ADC value of 1.5 that approved the highest sensitivity & specificity in differentiating benign from malignant pancreatic focal lesions. 相似文献48.
目的:建立电感耦合等离子体质谱(ICP-MS)法,测定香丹注射液中的铅(Pb)、 镉(Cd)、砷(As)、汞(Hg)、铜(Cu)。方法:分别以锗(Ge)、铟(In)、(Bi)为内标,采用ICP-MS 法同时测定5种元素的残留量;采用SPSS统计分析软件对不同厂家各批次之间及相同厂家不同批次之间的样品进行统计分析与评价。结果:所测元素标准曲线的相关系数均r>0.999,平均回收率为104%~122%,相对标准偏差(RSD)<7.9%。Cd和Pb的含量呈显著正相关性,Pearson相关系数为0.880;另外As和Pb、As和Cd的含量也有一定的相关性,Pearson相关系数分别为0.623和0.587。以上统计结果P值均小于0.05(具有显著性意义)。结论:该方法准确、快速、简便,可用于香丹注射液中重金属及有害元素的质量控制,也为横向评价各厂家生产的该药品质量提供辅助性参考。 相似文献

以OHSUMED语料库内提供的明确相关提问对为金标准和研究材料,借助BICOMB软件生成主题词-来源文献矩阵和共词矩阵,并获得各种系数的相似(相异)矩阵,对比分析目前国内基于SPSS共现聚类分析过程中主题词-来源文献矩阵与共现矩阵、各种相似性参数和各种类间距离计算方法的聚类效果。结果表明:主题词-来源文献矩阵聚类结果优于共词矩阵,在聚类分析中应优先选择。共词矩阵选择相似系数时应结合实际矩阵数据性质,并注意聚类方法原理上的正确性。 相似文献
