  • 简介:AbstractIncreasing evidence suggests that long non-coding RNAs (lncRNAs) are of vital importance for various biological processes, and dysregulation of lncRNAs is frequently associated with various diseases such as psoriasis. LncRNAs modulate gene expression at the transcriptional, post-transcriptional, and translational levels; however, the specific regulatory mechanisms of lncRNAs in psoriasis remain largely unexplored. This review provides an overview of recent studies investigating mechanisms and functions of lncRNAs in psoriasis, especially focusing on the role of lncRNAs in keratinocytes, T cells, and dendritic cells.

  • 简介:目的:分析非手术疗法治疗腰椎间盘突出症的近期、远期疗效。方法:将165例腰椎间盘突出症患者按随机和单盲法分为牵引组、推拿组,推拿加功能锻炼组,治疗2个疗程后,评定近期疗效。然后将取得显效的102例患者按区组随机和单盲法分为功能锻炼组和对照组,随访1年观察两组复发率,并分别于治疗后6和12个月进行腰椎功能评定。结果:推拿组和推拿加功能锻炼组较牵引组近期疗效显效率差异有显著性(x^2=8.359,P<0.01)。功能锻炼组1年内的复发率明显低于对照组(x^=12.631,P<0.01)。结论:推拿加功能锻炼是防治腰椎间盘突出症的有效方法。
