Combined occurrence of both congenital pulmonary airway malformation (CPAM) and esophageal cyst is rare and its diagnosis requires a carefully pathologic examination. Differential diagnoses include malignant neoplasms of pulmonary origin, pulmonary inflammatory pseudotumor, bronchogenic cysts and other congenital lesions of esophagus and lung. This paper presented a rare case report of a 31-year-old adult male with combined type III CPAM and an esophageal cyst.

Ribosomal protein S6 (rpS6), a component of the small 40S ribosomal subunit, has been found to be associated with multiple physiological and pathophysiological functions. However, its effects and mechanisms in non-small cell lung cancer (NSCLC) still remain unknown. Here, we showed that expressions of total rpS6 and phosphorylation rpS6 (p-rpS6) were both significantly overexpressed in NSCLC.

The standard definition of high-risk individuals for lung cancer was not uniform and the value of chest digital radiography (DR) in lung cancer screening was still unproven. The aim of this study was to assess whether the original questionnaire named as "Self-evaluation Scoring Questionnaire for High-risk Individuals of Lung Cancer" combined with DR examinations could detect early stage of lung cancer effectively. The Self-evaluation Scoring Questionnaire for High-risk Individuals of Lung Cancer had been designed in previous studies.

Methods: With the method of evidence-based medicine, risk factors of lung cancer were identified and their risk assignments were calculated to design the Self-evaluation Scoring Questionnaire for High-risk Individuals of Lung Cancer. Studies including more than 10 000 subjects were carried the out to confirm the questionnaire's value.
Proapoptotic BH-3-only protein Bad (Bcl-Xl/Bcl-2-associated death promoter homolog, Bad) initiates apoptosis in human cells, and contributes to tumorigenesis and chemotherapy resistant in malignancies. This study explored association between the Bad expression level and prognosis in patients with non-small cell lung cancer (NSCLC). In our study, a cohort of 88 resected primary NSCLC cases were collected and analyzed.
