急性百草枯中毒(APP)死亡率高,可引起多器官功能障碍甚至衰竭,临床治疗方案常采用多项措施联合的集束化治疗。故在患者就诊早期即对APP严重程度进行评估,能够为临床治疗方法的选择提供指导,对启动不同级别的治疗措施和预后改善都具有重要的临床价值。本文就早期评估APP严重程度及预后的研究进展做一述评。 相似文献

成纤维细胞生长因子21(fibroblast growth factor 21,FGF21)是一种多效应的内分泌因子,主要在肝脏和脂肪组织中分泌,具有降脂、抗炎、抗氧化和抗动脉粥样硬化作用。近年来发现,FGF21在心血管疾病中能够诱导保护作用,心血管疾病患者血浆中FGF21水平升高,可作为亚临床动脉粥样硬化的生物标志物,可作为动脉粥样硬化性心血管疾病的治疗靶点。故本文将对FGF21抗动脉粥样硬化作用的最新进展进行综述。 相似文献

Objective To explore the effects of dexamethasone on nuclear factor-kB (NF-κB) expression in brain tissue after traumatic brain injury (TBI). Methods Forty rats were randomly divided into two groups: dexamethasone treatment and no treatment, and severe brain injury was produced by gas percussion in both groups. At 0, 6, 24, 72 and 120 hours after injury, 5 rats of each group were executed and the histopathological changes in brain tissue in rats were observed by hematoxylin-eosin (HE) stain. The expression of NF-κB in brain tissue of rats was detected by immunohistochemical method. Results NF-κB expression was significantly up-regulated at 6 hours in brain tissue of rats after TBI (P<0.05), reaching the highest level at 24 hours (P<0. 01). It showed a tendency to lower, but was still high at 120 hours after TBI (P<0. 05 or P<0. 01). After treatment with dexamethasone, NF-κB level was lowered at 6, 24 and 72 hours (all P<0. 01). Conclusion NF-κB expression is up-regulated in brain tissue in early period after TBI, and keeps on a high level, thus inducing inflammatory response to produce secondary injury to brain tissue. Dexamethasone shows protective effects by regulating the levels of NF-κB and prevents secondary injury which is caused by the inflammatory cytokines in rat brain tissue after TBI. 相似文献

目的采用Meta分析比较因龋露髓恒牙使用三氧化钙无机聚合物(mineral trioxide aggregate,MTA)或氢氧化钙(calcium hydroxide,CH)进行直接盖髓以保存活髓的临床疗效。方法计算机检索Pubmed、Embase、中文生物医学文献数据库、中国期刊全文数据库、维普数据库、万方数据库,筛选国内外有关采用MTA或CH进行直接盖髓的龋坏恒牙活髓保存的临床研究,检索范围为建库至2015年7月15日。在严格筛选资料和质量评价的基础上,采用Rev Man5.3软件对纳入的研究结果进行Meta分析。结果共纳入9篇临床对照试验研究。Meta分析结果显示:使用MTA或CH直接盖髓治疗因龋露髓恒牙的疗效数据具有同质性,采用固定效应模型分析。MTA优于CH,差异有统计学意义(OR合并=3.65,95%CI=2.54~5.26,P<0.000 01)。结论使用MTA直接盖髓治疗因龋露髓恒牙的活髓保存效果良好,与CH比较,更适合作为直接盖髓材料。但由于本研究中部分文献的质量不高,纳入文献相对较少,上述结论还需要更多高质量,大样本的临床对照试验进一步验证。 相似文献
