Aim: The aim of this study is to explore the relationship between the neutrophil-to-lymphocyte ratio (NLR) and clinicopathological features in patients with papillary thyroid carcinoma (PTC). Methods: We performed an analysis of 843 patients, including 321 patients with PTC, 83 patients with thyroid adenoma and 439 patients with nodular goiter (NG). Thyroglobulin and thyrotropin were measured in each patient. Neutrophils, lymphocytes, and platelets were counted. Statistical analysis was used to correlate the NLR with demographic and histopathologic characteristics of the patients. Result: Age correlated with NLR and lymphocyte number in patients with PTC and NG. In patients aged >45 years, those with PTC had a higher NLR and a lower lymphocyte count than those with NG. Patients with PTC aged <45 years had a higher leukocyte count and a lower NLR than those aged ≥45 years. Patients with clinical stage I/II PTC had a lower NLR and a higher lymphocyte count than patients with stage III/IV. Conclusions: Younger patients with PTC had a higher lymphocyte count but a lower NLR than older patients with PTC. The NLR and lymphocyte counts were associated with the clinical stage. Thus, a higher NLR and a lower lymphocyte count may be prognostic for stratifying patients with thyroidal goiters and are risk factors of PTC for older patients.

Background. Noncystic fibrosis bronchiectasis (NCFB) is characterized by airway expansion and recurrent acute exacerbations. Macrolide has been shown to exhibit anti-inflammatory effects in some chronic airway diseases. Objective. To assess the efficacy of roxithromycin on airway inflammation and remodeling in patients with NCFB under steady state. Methods. The study involved an open-label design in 52 eligible Chinese patients with NCFB, who were assigned to control (receiving no treatment) and roxithromycin (receiving 150 mg/day for 6 months) groups. At baseline and 6 months, the inflammatory markers such as interleukin- (IL-)8, neutrophil elastase (NE), matrix metalloproteinase- (MMP)9, hyaluronidase (HA), and type IV collagen in sputum were measured, along with the detection of dilated bronchus by throat computed tomography scan, and assessed the exacerbation. Results. Forty-three patients completed the study. The neutrophil in the sputum was decreased in roxithromycin group compared with control (P < 0.05). IL-8, NE, MMP-9, HA, and type IV collagen in sputum were also decreased in roxithromycin group compared with the control group (all P < 0.01). Airway thickness of dilated bronchus and exacerbation were reduced in roxithromycin group compared with the control (all P < 0.05). Conclusions. Roxithromycin can reduce airway inflammation and airway thickness of dilated bronchus in patients with NCFB.
