BACKGROUND In patients with metastatic colorectal cancer(mCRC),the treatment options are limited and have been proved to be affected by rat sarcoma virus(RAS)mutational *** RAS wild-type(wt)patients,the combination of antiepidermal growth factor receptor(EGFR)monoclonal antibodies with chemotherapy(CT)is more effective than CT *** the other hand,RAS-mutated patients are not eligible for treatment with anti-EGFR *** SUMMARY Eleven patients with initially RAS-mutated mCRC were followed from diagnosis to May *** the time of cell-free DNA determination,five patients had undergone one CT line,five patients had undergone two CT lines,and one patient had undergone three CT lines(all in combination with bevacizumab).At the second and third treatment lines[second line(2L),third line(3L)],patients with neo-RAS wt received a combination of CT and *** neo-RAS wt patients treated with anti-EGFR,our findings indicated an increase in progression-free survival for both 2L and 3L(14.5 mo,P=0.119 and 3.9 mo,P=0.882,respectively).Regarding 2L overall survival,we registered a slight increase in neo-RAS wt patients treated with anti-EGFR(33.6 mo vs 32.4 mo,P=0.385).At data cut-off,two patients were still alive:A RAS-mutated patient undergoing 3L treatment and a neo-RAS wt patient who received 2L treatment with anti-EGFR(ongoing).CONCLUSION Our case series demonstrated that monitoring RAS mutations in mCRC by liquid biopsy may provide an additional treatment line for neo-RAS wt patients.

内侧前额叶皮质(mPFC)参与诸如工作记忆等认知功能。星形胶质细胞大麻素1型受体(CB1R)诱导细胞质内钙离子(Ca2+)浓度变化,对神经元功能产生影响。mPFC的星形胶质细胞也表达腺苷A1和A2A受体(A1R,A2AR),但目前尚不清楚这些细胞中的CB1R与腺苷受体之间的交流。我们在这里展示,通过CB1R-A2AR或CB1R-A1R异源二聚体,星形胶质细胞Ca2+信号传递发生了进一步的调节,最终影响mPFC突触可塑性。当A1R和A2AR被激活时,CB1R介导的Ca2+瞬变出现增加或减少,揭示了腺苷受体可能是星形胶质细胞CB1R的调节器。CB1R的激活导致mPFC的长时程增强(LTP)增强,受A1R控制,但不受A2AR控制。值得注意的是,在IP3R2KO小鼠中,由于没有显示出星形胶质细胞Ca2+水平升高,CB1R的激活减少了LTP,这种效果不受A1R或A2AR的调节。本研究表明,CB1R在mPFC LTP上具有稳态作用,受到A1R的控制,可能是由于这些受体在星形胶质细胞中的交流,最终改变了CB1R Ca2+信号传递。

目的旨在通过系统综述,确定针对复杂慢性病患者增强自我管理的干预措施,以改善慢性呼吸困难,为护理人员促进该类人群的自我管理提供依据。方法2023年12月,系统检索Medline、Scopus、Web of Science、CINAHL、Cochrane图书馆和乔安娜布里格斯研究所(Joanna Briggs Institute,JBI)循证实践数据库。对纳入研究进行数据提取和综合,研究人员采用Rayyan文献管理软件筛选标题及摘要,并依据JBI研究质量评估工具进行方法学质量评估。结果共纳入18项研究。这些研究探讨了针对慢性呼吸困难的各种干预措施,包括药物干预(氧气疗法和吸入疗法)和非药物方法(教育计划、呼吸练习、液体摄入管理、身体感知技术、同伴支持、情商培训和网络应用程序的使用)。这些干预措施减轻了患者情绪困扰,可以使患者在自我管理方面变得独立自主。结论促进复杂慢性病患者对慢性呼吸困难的自我管理需要采取综合方法,但目前研究中没有充分考虑到针对患者行为改变的干预措施,需要进一步开展相关研究完善干预措施。

位于巴西利亚的圣家族教堂由ARQBR Arquiteturae Urbanismo打造设计。“当我看到这片高原,那漫无边际的地平线,极为广衰。它的尺度超乎寻常——就像一片海洋,上面飘着大片白云。通过将城市置于其中,我们将创造出一种绝无仅有的景观。”巴西著名建筑师兼城市规划师Lucio Costa在多年前为巴西新首都巴西利亚选址后,讲述了他对这片土地的看法和感受。他不仅概括出了这里的景观特点,即广阔的地平线,同时也构成了巴西利亚最初的城市规划概念。
