目的:探讨lncRNA LINC-PINT通过miR-425-5p/PTCH1轴对喉癌细胞干性的影响.方法:采用实时定量聚合酶链反应(qRT-PCR)方法将LINC-PINT全长序列扩增并转染到HEp-2细胞,应用Diana Tools、双荧光素酶报告分析系统分别预测和验证LINC-PINT及miR-425-5p的分子靶标,应用qRT-PCR和Western blot检测LINC-PINT和癌细胞干性相关基因(Sox-2、CD44、CD133和Nanog)及其蛋白的表达.结果:转染LINC-PINT后证实LINC-PINT过表达会引起癌细胞干性相关基因表达下调,抑制miR-425-5p可引起癌细胞干性相关基因表达下调;LINC-PINT的分子靶标为miR-425-5p,且miR-425-5p的分子靶标为PTCH1.结论:LINC-PINT通过miR-425-5p/PTCH1轴抑制喉癌细胞干性而抑制喉癌的发生.

越来越多的研究发现,参与细胞焦亡中的NLRP3炎症小体被抑制启动或激活后,可以起到一定的减少神经炎症反应、延缓神经退行性疾病进展的作用.因此,现就依赖NLRP3炎症小体的细胞焦亡在神经退行性疾病中的最新研究进展进行综述.
In children and adolescents,syncope is common and accounts for a considerable proportion of emergency vis-its.The underlying diseases of pediatric syncope mainly include neurally mediated syncope (NMS) and cardiogenic conditions.NMS accounts for 70-80％ of
目的 探究肠内营养支持干预在高脂血症胰腺炎患者中的疗效观察及对营养状态的影响研究.方法 选取2019年2月至2021年3月我院收治的106例高脂血症胰腺炎患者,随机分成2组,每组53例,对照组接受肠外营养支持干预,研究组则接受肠内营养支持干预,比较2组的疗效及营养状态.结果 与对照组比,研究组的治疗效果更优(P<0.05);治疗2周后,与对照组比,研究组的免疫状态指标更优(P<0.05);治疗2周后,与对照组比,研究组的炎性因子指标更低(P<0.05);治疗2周后,与对照组比较,研究组的营养状态指标更优(
