概括
一个新的通风-输液容量差异指数 (VQCDI) 准确地预测了手术或SABR后治疗后的肺功能. 这种方法在当前基于体积的预测中得到了改进,特别是在复杂的情况下.
科学领域:
- 肺部医学 肺部医学
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 准确预测治疗后的肺功能对于选择治疗疗法至关重要,例如用于早期肺癌的手术和刻板体移除性身体放射疗法 (SABR).
- 目前用于预测术后 (PPO) 肺功能的方法依赖于叶片体积,它忽略了区域通风和 perfusion 变化,特别是在患病的肺部.
- 评估定量通风/ perfusion 单光子发射计算机断层扫描/计算机断层扫描 (V/Q SPECT/CT) 的可行性,以改善治疗后的肺功能预测是必不可少的.
研究的目的:
- 开发和评估一种新的指数,即通风-输液容量差异指数 (VQCDI),用于量化叶片对肺功能的贡献.
- 评估V/Q SPECT/CT在接受肺癌治疗的患者肺功能区域定量方面的可行性.
- 为了比较VQCDI的预测准确度与传统的CT基于肺功能治疗后体积预测.
主要方法:
- 开发了一种新的通风-输液容量差异指数 (VQCDI),使用内部软件来量化叶膜通风,输液和体积.
- 在区域量化软件中启用手动注释手术边缘和辐射场.
- 预期招募的患者接受了叶叶切除术,亚叶叶切除术或SABR,将VQCDI预测与治疗后6个月的肺功能测量 (FEV1,DLCO,DLCOc) 进行比较.
主要成果:
- 在手术患者的治疗后FEV1预测中,VQCDI显示出强烈的相关性 (R=0.920,ICC=0.908),优于体积预测.
- 在手术参与者中,VQCDI还显示了肺部对一氧化碳 (DLCO) 和血红蛋白校正的DLCO (DLCOc) 的扩散能力的强烈相关性 (R=0.899-0.921).
- 通过不同类型的手术 (分叶切除术,分叶切除术) 和患者病情 (吸烟者,肺气) 保持了高预测性表现,在SABR后评估放射性肺炎方面具有潜在的实用性.
结论:
- 透气-输液容量差异指数 (VQCDI) 是一个可行的和准确的工具,用于预测治疗后的肺功能.
- VQCDI提供了新的功能,用于评估肺功能后,亚叶叶切除和立体除体辐射疗法 (SABR).
- 建议进行进一步的多中心研究,并进行延长的随访,以验证这些发现.

pre-mRNA Processing
57.6K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.
