1相关性和一致性:这对相仿概念和测量方法的回顾与阐明(英文)显示文摘一致性(agreement)和相关性(correlation)是两个广泛使用的概念,用来评估变量之间的关联。虽然二者相似且相关,但是它们代表关联完全不同的概念。评估变量之间的一致性假设变量测量的是相同的结构,而在变量测量完全不同的结构时也可以评估它们之间的相关性。这种概念上的差异就要求使用不同的统计方法,并且当评估一致性或相关性时,统计方法根据数据的分布和研究者的兴趣可能会有所不同。例如,Pearson相关性,作为评估连续变量之间相关性的一种普遍测量方法,只有用于符合线性关系的变量时才能提供有用的信息;当用于不符合线性关系的变量时就无法提供准确信息甚至会产生误导。同样地,内部相关性,作为一种评估连续变量之间一致性的常用方法,如果一致性不好的实质正好是研究兴趣所在,那么该测量就不能为研究者提供充分的信息。本报告回顾了一致性和相关性的概念,并讨论了几种常用方法在应用中的差异。Liu JY Tang W Chen GQ Lu Y Feng CY Tu XM 2016上海精神医学2016,28,2:6
2RNA secondary structures located in the interchromosomal region of human ACAT1 chimeric mRNA are required to produce the 56-kDa isoform显示文摘我们以前报导了人的 ACAT1 基因通过从染色体抄录的二不连续的 RNA 处理的 interchromosomal 生产妄想的 mRNA 1 和 7。妄想的 mRNA 把 AUG1397-1399 和 GGC1274-1276 用作翻译开始 codons 分别地,与在人的房间是确实地在场的后者生产正常 50-kDa ACAT1 和新奇酶地活跃的 56-kDa isoform,包括人的导出单核白血球的巨噬细胞。在这个工作,我们报导位于 GGC1274-1276 codon 的附近的 RNA 第二等的结构为 56-kDa isoform 的生产被要求。三预言的茎环(nt 1255-1268, 1286-1342 和 1355-1384 ) 的效果被 transfecting 表示 plasmids 个别地测试进包含的房间野类型,删除或变异的茎环序列连接了到一个部分 ACAT1 8 月开的读物框架(ORF ) 或到另外的基因的 ORF。表示模式被西方的污点分析监视。我们发现从染色体 7 的在上游的 stem-loop1255-1268 和从染色体 1 的下游的 stem-loop1286-1342 为 56-kDa isoform 的生产被需要,而从染色体 1 的最后 stem-loop1355-1384 是非必需的。用有一个稳定的发卡的 monocistronic 和 bicistronic 向量的实验的结果证明从 GGC1274-1276 codon 的那翻译开始被一个内部核糖体入口地点(怒火) 调停。进一步的实验表明从 GGC1274-1276 codon 的那翻译开始要求在上游的组成 AU 的 RNA 第二等的结构和下游地 GC 富有的结构。这个机械学的工作为人的 ACAT1 抄本的妄想的性质的生物意义提供进一步的支持。Jia Chen Xiao-Nan Zhao Li Yang Guang-Jing Hu Ming Lu Ying Xiong Xin-Ying Yang Catherine CY Chang Bao-Liang Song Ta-Yuan Chang Bo-Liang Li 2008Cell Research2008,18,9:5
3Nitrite-derived nitric oxide by xanthine oxidoreductase protects the liver against ischemia- reperfusion injury显示文摘It was demonstrated that xanthine oxidoreductase (XOR), during ischemia, catalyzes the formation of nitric oxide (NO) from nitrite (NO2-) and this NO2--derived NO protects the isolated perfused rat heart against the damaging effects of ischemia-reperfusion (I/R) when conventional nitric oxide synthase (NOS) -dependent NO production is impaired. Liver is one of the organs with the highest XOR concentration. This study was designed to determine whether NO2--derived NO by XOR protects liver against I/R injury in vivo. For its minute amounts and active reactivity, NO can not be detected directly in real time in vivo by this time. We have to prove the above hypothesis indirectly. METHODS:Wistar rats were pretreated with saline, NOS inhibitor L-NAME (10 mg/kg intravenously), XOR inhibitor allopurinol (1.5 mg/kg orally), L-NAME +allopurinol and NO scavenger carboxy-PTIO (0.6 mg/kg intravenously) respectively (12 animals per group). And then, they were subjected to total liver ischemia for 40 minutes followed by reperfusion. Blood samples and liver tissues were obtained for analysis after 3 hours of reperfusion. Survival was also investigated. RESULTS:Allopurinol-treated animals exhibited further increased serum alanine aminotransferase (ALT) levels and liver myeloperoxidase (MPO) activities, but further decreased liver adenosine triphosphate (ATP) stores after I/R compared to saline-treated counterparts (830.5±108.3 U/L, 56.5±11.0 U/mg protein and 1.93±0.47 μmol/g vs. 505.8± 184.2 U/L, 41.5±10.2 U/mg protein and 3.05±0.55 μmol/g respectively, P<0.01, P<0.05 and P<0.01 respectively). The hepatocyte injury was further exacerbated and the overall survival rate was significantly decreased after I/R in animals given by allopurinol compared to those pretreated by saline (P<0.05). L-NAME and allopurinol co-treated animals exhibited more severe liver injury (P<0.05 and P<0.01) and a further decreased overall survival rate (P<0.05) compared to L-NAME or allopurinol alone-treated counterparts, but they were not different from carboxy-PTIO treated animals (P>0.05). CONCLUSION:NO2--derived NO by XOR in the hypoxic and acidic environment induced by hepatic I/R protects the liver against I/R injury in vivo.Department of General Surgery ( Lu P, Wang CY and Chen DD), and Department of Radiology (Liu F), Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430022, China Cold Spring Harbor Laboratory, New York 11724, USA ( Yao Z) General Surgery Laboratory, Union Hospital, Tongji Medical College , Huazhong University of Science and Technology, Wuhan 430022 , China (Tian Y, Zhang JH and Wu YH) 2005Hepatobiliary & Pancreatic Diseases International2005,4,3:4
