Epidermal growth factor receptor (EGFR) exon 20 insertion ( ex20ins) is a common mutation in non-small cell lung cancer (NSCLC). Patients with ex20ins generally respond poor to EGFR-tyrosine kinase inhibitors (EGFR-TKIs). ex20ins are often co-occurring with amplification. However, the impact of amplification on the survival of patients with ex20ins mutations has not been determined. This is an observational longitudinal cohort study. A prospectively managed database included consecutive treatment-naïve adult patients with advanced NSCLC and ex20ins confirmed by next-generation sequencing (NGS) at Guangdong Provincial People's Hospital between November 2017 and February 2019. The participants were enrolled from the database and extracted their clinical characteristics, treatment and clinical outcomes. NGS was used to establish whether amplification was present in tumor tissue. Overall survival (OS) and progression-free survival (PFS) were compared between amplification and non- ification group than in the amplification group (110 . 31 days, P=0.030). There is a tendency that amplification might be a poor predictor in ex20ins-positive NSCLC patients treated with EGFR-TKIs. There is a tendency that EGFR amplification might be a poor predictor in EGFR ex20ins-positive NSCLC patients treated with EGFR-TKIs. Coronary artery aneurysm (CAA) and coronary artery ectasia (CAE) may be two different types of coronary artery dilatation with unknown etiology. This study aimed to compare the differences between CAA and CAE and to investigate their pathogenesis and the necessity of antiplatelet therapy. One hundred patients each with confirmed CAA, CAE, and normal coronary artery (NCA) from September 2017 to July 2019 were included. All patients completed examinations of the ankle-brachial index (ABI), pulse wave rate, and carotid ultrasonography; and were tested for routine blood, lipid, and immune parameters. Blood samples were collected 1 week after the withdrawal of antiplatelet drugs, and vascular inflammatory indexes, platelet activation indexes, thromboelastography, and the platelet aggregation rate were measured. Analysis of variance and the chi-square or Fisher exact test were used for statistical analysis. The perinuclear anti-neutrophil cytoplasmic antibody (ANCA), endothelial-1, matrix metalloproteinase-9,ificantly higher in CAE than in NCA. CAE was closely related to inflammation, whereas CAA was closely related to atherosclerosis. Platelet activation was present in both diseases; therefore, antiplatelet therapy is recommended.

Pneumothorax refers to the abnormal presence of air in the thoracic cavity. Pulmonary emphysema (PE) is often detected during computed tomography (CT), one of the radiological investigations used to diagnose pneumothorax and devise treatment plans in former or current smokers who present with pneumothorax. However, there are few reports that describe the recurrence rate and risk factors associated with recurrence in patients with PE and pneumothorax. This study retrospectively cross-sectional analyzed the medical records of 164 patients diagnosed with their first episode of secondary spontaneous pneumothorax and admitted to a tertiary care hospital, between March 2013 and February 2019. The CT scans of 98 patients revealed PE, and 49 patients of those underwent pulmonary function tests (PFTs) after the resolution of pneumothorax. selleck Risk factors for recurrence were analyzed using Cox proportional hazard regression. All the subjects were male and former or current smokers, with a median age of 72 years. Thiicting
