概括
这项研究跟踪了手术后肺癌患者的代谢变化. 一些代谢物水平在手术后恢复到正常水平,但另一些仍然改变,可能有助于治疗监测.
科学领域:
- 在瘤学瘤学.
- 代谢学 代谢学 代谢学
- 生物化学 生物化学
背景情况:
- 肺癌 (LC) 是一个主要的全球健康问题,手术是早期阶段的主要治疗方法.
- 监测手术后的代谢变化可以告知治疗反应和复发检测.
- 了解这些代谢变化对于改善患者的治疗结果至关重要.
研究的目的:
- 为了分析肺癌患者手术前后的血清代谢概况.
- 为了比较两个不同的术后时间点 (1个月和3-6个月) 与健康对照的新陈代谢概况.
- 为了确定在外科手术后发生变化的特定代谢物.
主要方法:
- 使用了一个非向的代谢学平台,结合了逆相 (RP) 和水友互动色谱 (HILIC).
- 采用超高性能液态染色学 (UHPLC) 与质谱学 (MS) 结合进行全面分析.
- 分析了110名肺癌患者 (手术前和术后) 和健康对照的血清样本.
主要成果:
- 在研究组中确定了22种显著变化的代谢物.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
