Analysis of clinical characteristics of 150 cases of pediatric hepatitis caused by nonhepatotropic pathogen

  • Published Date: 2011-07-20
  • Objective To study the clinical characteristics of pediatric hepatitis caused by nonhepatotropic pathogen.Methods Retrospective analysis of the clinical characteristics of 150 cases diagnosed with non-hepatotropic pathogen related hepatitis in pediatric gastroenterology department, Shengjing hospital during Jan, 2009 to Sept, 2010 were studied.Results There were 81 males and 69 females in the 150 cases.Mycoplasma pneumoniae and EB virus were the main causes of the non-hepatotropic pathogen related hepatitis, with 69 cases (46%) and 59 cases (39.33%) respectively.Compared with pre-treatment, there were significant reduction in the level of ALT and AST (P<0.05) after treatment.Conclusion The results show that the clinical manifestations of non-hepatotropic pathogen related hepatitis are nonspecific.ALT and AST can be used to confirm the diagnosis.Early diagnosis and treatment are the key points to improve the prognosis.

     

  • 在肝细胞癌(HCC)的治疗中,放射治疗日益成为一种重要的治疗策略。然而,对放射治疗的抵抗是成功治疗的主要障碍之一。因此,该研究旨在阐明放射抵抗的机制,并寻找可靠的生物靶点,以提高HCC放射治疗的疗效。

    从无标记的定量蛋白质组筛选中,确定转移RNA(tRNA;鸟嘌呤-N[7]-)甲基转移酶1(METTL1)是N7-甲基鸟苷(M7G)tRNA修饰的关键酶,是HCC细胞辐射抗性的重要驱动因素。通过体外和体内功能丧失及功能获得实验分析,发现METTL1促进DNA双链断裂(DSB)修复,并使HCC细胞对电离辐射产生抵抗。

    在机制上,METTL1介导的M7G tRNA修饰选择性地调节电离辐射处理后DNA依赖的蛋白激酶催化亚基或DNA连接酶Ⅳ的翻译,从而导致非同源末端连接(NHEJ)介导的DNA DSB修复效率提高。临床上,肿瘤组织中METTL1的高表达与接受放射治疗的HCC患者的不良预后显著相关。

    研究表明,METTL1是电离辐射治疗后HCC细胞基于NHEJ的DNA修复的关键增强剂。这些发现有助于了解tRNA修饰在信使RNA翻译控制中的作用。
