目的探讨人肝细胞株L02脂肪变性时微小RNA-29a(miR-29a)的表达变化及其靶向沉默信息调节因子2相关酶类1(silent mating type information regulation 2 homolog-1,Sirt1)调节脂肪肝细胞脂肪沉积的机制。方法采用油酸和棕榈酸混合物诱导建立非酒精性脂肪肝细胞模型,验证模型成功后,PCR检测miR-29a和Sirt1的表达变化;生物学预测miR-29a的靶基因;分别转染miR-29a模拟物和抑制剂,过表达miR-29a和抑制miR-29a后再建立人脂肪肝细胞模型。油红O染色观察细胞中脂质蓄积情况并测定甘油三酯含量,荧光定量PCR和免疫印迹法检测Sirt1基因和蛋白表达变化。结果脂肪肝细胞模型组miR-29a相对表达量和甘油三酯含量显著高于对照组(P<0.01),Sirt1相对表达量显著低于对照组(P<0.01);生物学预测Sirt1是miR-29a的靶基因,过表达miR-29a后,细胞内脂滴明显增多,脂肪沉积加重,甘油三酯含量显著增加(P<0.05),细胞中miR-29a的表达显著上调(P<0.01),而Sirt1 mRNA表达显著下调(P<0.05),Sirt1蛋白表达呈下降趋势;与之相反,抑制miR-29a后,细胞中脂滴相对减少,脂肪沉积减轻,甘油三酯含量显著下降(P<0.05),细胞中miR-29a的表达被有效抑制(P<0.01),而Sirt1 mRNA的表达显著上调(P<0.05),Sirt1蛋白表达较对照组呈上升趋势。结论 miR-29a在非酒精性脂肪肝细胞中表达显著上调,miR-29a通过表达上调负调控Sirt1表达从而促进脂肪肝细胞中脂肪沉积。 相似文献

Blood donation in China: sustaining efforts and challenges in achieving safety and availability 下载免费PDF全文
China has entered a new phase in blood safety and availability through persistent efforts in the past decades. Based on national data from 2008 to 2012, we present a comprehensive review on the blood services ranging from policy and organization, supply, donors, screening and processing, and clinical use to government response in contemporary China. Current evidence suggests that the Chinese blood industries, after continual efforts in reforms on the legal framework and national management system, have been in a relatively steady but bottleneck stage. Although the blood industries have had an impressive track record on management and resolving problems, such as low availability, limited donors, deficient laboratory tests, shortage of blood products, and unnecessary clinical usage of blood still exist nationwide. While medical technology and services have seen a rapid increase in progress in recent years, they have not coordinated with the development of the national health care system. This article presents an analysis with detailed data, rich contents, and recent response from the Chinese government, allowing readers to appreciate how China, a country with more than 19.13% of the world's population, has long endeavored to improve safety and availability of blood. Meantime, the article sincerely welcomes the guidance on policymaking and technical assistance from the international community. Data in this article do not include those of Hong Kong, Macao, or Taiwan. 相似文献

Monocarboxylates cannot cross the blood-brain barrier freely to participate in brain energy metabolism. Specific monocarboxylate transporters (MCTs) are needed to cross cellular membranes. Monocarboxylate transporter 2 (MCT2) is a major monocarboxylate transporter encoded by the SLC16A7 gene. Recent studies reported that neurodegenerative diseases of the CNS, such as Alzheimer's disease (AD) and Parkinson's disease (PD), were related to energy metabolic impairment. MCT2 also plays an important role in energy metabolism in the CNS. To provide experimental evidence for future research on the role of MCT2 in the pathological process of CNS degenerative diseases, the distribution and density of MCT2 in different subregions of wild-type mouse brain was examined using immunohistochemistry, western blot and immunogold post-embedding electron microscopic techniques. The amount of MCT2 was higher in cerebellum than in cortex and hippocampus on western blots, and there was no statistical difference between cortex and hippocampus. Immunohistochemistry assay revealed the highest density of MCT2 in the CA3 of the hippocampus. The granular cell layer of the cerebellum contained more MCT2 than the molecular layer. The MCT2 density on the end feet of astrocytes of molecular layer was lower than in hippocampus, but the postsynaptic densities (PSDs) of asymmetric synapses in the molecular layer exhibited a high density using immunogold post-embedding electron microscopic techniques. 相似文献

目的探索基于增量费用比的医用耗材分类的循证评价方法并进行实证检验。方法借鉴四象限图进行耗材证据分类探索。结果医用耗材管理科推荐的项目中95.22%获得小组推荐,小组推荐的项目100%通过委员会决议。医用耗材管理科意见、小组意见与委员会决议的相关性较高。结论 "一维度"模型更利于小组意见生成与委员会决策。以诊疗技术所需耗材整体费用为基础,更接近实际情况。分类临界值有待进一步优化,分类依据需根据医院情况不断调整。基于增量费用比的医用耗材循证证据分类评价方法是一种适合中国国情的、简单快速的医院卫生技术评估方法。 相似文献

通过对我国当前职业病病人经济风险分担机制及其问题进行剖析发现,我国职业病病人经济风险分担机制是用人单位为主要负担者、政府保基本、个人或非盈利组织为补充,但实践中还存在诊断和鉴定过程比较繁琐、落实工伤待遇比较困难、赔偿和其他保障救助不到位等问题。建议更加重视应对职业病病人经济风险,诊断鉴定过程中让劳动者少跑路、少等待、少提供材料、少额外开销,施行《工伤保险条例》时让劳动者应参保尽参保、应赔付尽赔付、保障水平“就高不就低”,同时,充分利用现有大病救助制度,鼓励利用市场机制分散病人经济风险,拓宽救助渠道,提高救助精准性。 相似文献
