肺癌

研究人员研制开发了一种新的诊断平台可以早期诊断癌症，在呼出的气体中找到代表肺存在病理细胞的蛋白生物标记。
肺癌诊断出来越早，治愈的机会就越大。但早期诊断是困难的，因为在肺癌早期表现为慢性炎症反应。为了明确诊断，患者需要进行X线检查或支气管镜检查，而后者可能对肺会产生刺激，或需要取走组织样本，这对患者来说很难接受。
德国的科学家研究出一种方法，可以检测呼气中的特殊蛋白生物标记物。存在这种生物标记物就意味着肺中存在肿瘤细胞。为了完成检查，患者需要向一种设备呼吸大约20分钟时间。呼出的气体进行冷凝和浓缩，然后通过能够识别这种特殊蛋白的抗体进行标记物检测。该蛋白能够刺激新血管的生长。
这个项目未来两年的目标是生产出一个原型，进而用于临床诊断的研究，并在将来发展到生产阶段。

The researchers developed a new diagnostic platform for early diagnosis of cancer found in the exhaled breath of lung exists on behalf of the pathological cells of the protein biomarkers.
Lung cancer diagnosed earlier, the greater the chance of cure. But early diagnosis is difficult, because in the early manifestation of chronic lung inflammation. In order to confirm the diagnosis, patients need X-ray or bronchoscopy, which may cause stimulation of the lung, or require removal of tissue samples, it is difficult to accept the patient.
German scientists developed a method to detect specific proteins breath biomarkers. The existence of such biological markers present in the lung means that tumor cells. To complete the examination, patients need a device to breathe about 20 minutes. Exhaled gas condensation and concentration, and then be able to identify this particular marker protein antibody detection. The protein can stimulate the growth of new blood vessels.
The next two years the project aims to produce a prototype, and then used for clinical diagnosis, and in the future development to production stage.
