Background
Human telomerase reverse transcriptase (hTERT) is the catalytic subunit of telomerase enzyme, which adds nucleotides to telomeres and counteracts their length shortening. The development of a telomere maintenance mechanism represents a hallmark of cancer. On the other hand, idiopathic pulmonary fibrosis (IPF) is associated with mutations in telomerase genes and shorter telomeres. IPF is frequently complicated with lung cancer.
Aim
To investigate the expression of hTERT in lung cancer with co-existing IPF and to compare with lung cancer without fibrosis.
Methods
Diagnostic lung cancerous biopsies were retrieved from 18 patients with lung cancer and concomitant IPF, as well as 18 age and gender matched controls with lung cancer without pulmonary fibrosis. The expression of hTERT was studied with immunohistochemistry. ImajeJ software was used to quantitate subcellular stain intensity. Immunohistochemical investigation of two senescence-associated markers, p16 and p21, was also performed in all 36 cases.
Results
Both groups highly expressed hTERT, without significant difference (100% vs 95%, p = 0.521). Evaluation of p16 and p21 immunostaining revealed negative to minimal immunoreactivity in both groups. hTERT localization exhibited higher median nuclear intensity in the group of lung cancer with IPF (0.62 vs 0.45, p = 0.016), while cytoplasmic intensity did not differ significantly (0.17 vs 0.15, p = 0.463). Higher median nuclear intensity was also correlated with small cell lung cancer subtype in the whole study sample (0.69 vs 0.45, p = 0.09).
Conclusion
hTERT is highly expressed in lung cancer with concomitant IPF, but with differential localization compared to lung cancer without IPF, implying differences in pathogenicity and requiring further investigation.

Introduction
Computed tomographic (CT) phenotypic patterns of chronic obstructive pulmonary disease (COPD) identify different clinical features of disease. The impact of these variables on the physiological response to exercise has been the focus of a great deal of research as it allows more individualized clinical approaches. The aim of our study was to evaluate the relationships between CT phenotyping of subjects with COPD and the ventilatory response during cardiopulmonary exercise testing (CPET).
Methods
Subjects with COPD were classified into four phenotypes based on CT metrics of emphysema (low attenuation area less than a threshold of -950 Hounsfield [%LAA-950]) and airwall thickness (bronchial wall area percentage [%WA]).
Results
Eighty COPD patients (78.8% males, median age 65±11.3 years) were enrolled in the study. Based on CT phenotype, 25 (31.3%) patients were classified as normal, 27 (33.8%) air dominant, 17 (21.3%) emphysema dominant and 11 (13.8%) mixed type. The emphysema and mixed phenotypes showed the highest ventilatory equivalent for carbon dioxide (VE/VCO2) and VE/VCO2 slope (p<0,05). In all phenotypes, %LAA was positive correlated with VE/VCO2 and VE/VCO2 slope (r = 0.437, p = 0.006 and r = 0.503, p<0.001, respectively). %WA also showed a positive correlation with VE/VCO2 and VE/VCO2 slope (r = 0.541, p<0.001 and r = 0.299, p = 0.033, respectively). In multivariate regression models, after adjustment for age, BMI, sex and FEV1, %LAA was the only independent predictor of VE/VCO2 and VE/VCO2 slope (β 0.343, SE 0.147, 95% CI 0.009/0.610, p = 0.044 and β 0.496, SE 0.081, 95% CI 0.130/0.455, p = 0.001, respectively).
Conclusion
Emphysema (%LAA) and airways metrics (%WA) had strong relationships with the different characteristics of ventilatory response to exercise in subjects with mild to moderate COPD. In particular, %LAA seemed to play an important role as an independent predictor of VE/VCO2 and VE/VCO2 slope. These results suggested that CT phenotyping may help predicting ventilatory response to exercise in subjects with COPD.
简介：慢性阻塞性肺病（COPD）的计算机断层扫描（CT）表型模式可确定疾病的不同临床特征。这些变量对运动生理反应的影响一直是大量研究的焦点，因为它可以使临床方法更加个体化。我们的研究旨在评估慢性阻塞性肺病受试者的 CT 表型与心肺运动测试（CPET）期间通气反应之间的关系：根据肺气肿（低衰减面积小于-950 Hounsfield[%LAA-950]阈值）和气壁厚度（支气管壁面积百分比[%WA]）的 CT 指标，将慢性阻塞性肺病受试者分为四种表型：80 名慢性阻塞性肺病患者（78.8% 为男性，中位年龄为 65±11.3 岁）参加了研究。根据 CT 表型，25 例（31.3%）患者被归类为正常型，27 例（33.8%）为空气优势型，17 例（21.3%）为肺气肿优势型，11 例（13.8%）为混合型。肺气肿和混合表型的二氧化碳通气当量（VE/VCO2）和 VE/VCO2 斜率（pE/VCO2 和 VE/VCO2 斜率（r = 0.437，p = 0.006 和 r = 0.503, pE/VCO2 and VE/VCO2 slope (r = 0.541, pE/VCO2 and VE/VCO2 slope (β 0.343, SE 0.147, 95% CI 0.009/0.610, p = 0.044 and β 0.496, SE 0.081, 95% CI 0.130/0.455, p = 0.001, respectively).结论：肺气肿（%LAA）和气道指标（%WA）与轻度至中度慢性阻塞性肺疾病患者运动时通气反应的不同特征有密切关系。尤其是，肺气肿%LAA似乎是VE/VCO2和VE/VCO2斜率的独立预测因子。这些结果表明，CT 表型可能有助于预测慢性阻塞性肺病患者运动时的通气反应。
