简介:什么叫蓝V?蓝V就是微博认证对企业或者社会机构标的蓝色“V”。它们主要是在微博宣传自己的企业或机构,看上去很严肃,很高大上;什么叫段子手?段子手就是在微博上以发无厘头搞笑内容为主的个体,他们的形象是嬉皮笑脸的。两个角色虽然都是混迹在微博上,但好像也是两条平行线,风马牛不相及的。不过现在情况有了变化,这些本来应该打着官腔说些场面话的蓝V们变得越来越接地气起来,话也捡着有趣好玩的说,跟爆点,蹭热度,编笑话。以往大家都不太关注蓝V的微博的,但是这些家伙变得越来越有意思了,同样一个笑话,通过蓝v的嘴说出来,因为它们身份的加持,感觉就变得不不一样了呢!
简介:摘要肝脏是结直肠癌血行转移最主要的靶器官,结直肠癌肝转移是结直肠癌治疗的重点和难点之一。为了提高我国结直肠癌肝转移的诊断和综合治疗水平,自2008年起联合编写《中国结直肠癌肝转移诊断和综合治疗指南》并后续进行了多次修订,以期指导对结直肠癌肝转移患者进行全面评估,精准地制定个体化的治疗目标,开展综合治疗,达到预防肝转移发生、提高肝转移灶局部毁损率、延长长期生存和改善生活质量的目的。本次修订后的2023版《指南》包括结直肠癌肝转移的诊断和随访、预防、MDT作用、手术及其他毁损治疗、可达到“无疾病证据”状态结直肠癌肝转移的新辅助和辅助治疗、无法达到“无疾病证据”状态结直肠癌肝转移的综合治疗等六部分,汇集总结国内外该领域的先进经验和最新成果,内容详尽,可操作性强。
