Correlation analysis on the association of composite dietary antioxidant index with serum cotinine levels in the general adult population.

Objectives: This study utilized data from the National Health and Nutrition Examination Survey (1999-2020) to explore the relationship between dietary antioxidant intake and serum cotinine levels among US adults.

Methods: A total of 41 132 participants were included after exclusions. The composite dietary antioxidant index (CDAI), incorporating vitamins A, C, and E, zinc, selenium, and carotenoids, was derived from 24-hour dietary recalls.

Value of ultrathin bronchoscope in improving the endobronchial ultrasound localization rate and diagnosing peripheral pulmonary nodules by cryobiopsy.

Background: A 3.0-mm ultrathin bronchoscope (UTB) with a 1.7-mm working channel provides better accessibility to peripheral bronchi.

The value of calcofluor white in the diagnosis of invasive fungal diseases.

Purpose: To evaluate the value of calcofluor white in the diagnosis of invasive fungal disease (IFD).

Methods: A total of 84 patients with possible pulmonary fungal infection who underwent bronchoscopy with bronchoalveolar lavage fluid (BALF) were included. All BALF specimens were subjected to Calcofluor white (CFW), potassium hydroxide (KOH) and Gram stains.

Advice for smokers in smoking cessation clinic: a review.

Background: Tobacco dependence has become a global public health concern. We chose to investigate the modifiable factors and motivations during the period of smoking cessation based on the mechanism of nicotine addiction.

Methods: We selected emotion, sleep, alcohol, caffeine beverages, mental activities after dinner, exercise and CYP2A6 genotype as influencing factors, and provided corresponding recommendations for smokers based on these factors.

Diagnostic performance of cryobiopsy guided by radial-probe EBUS with a guide sheath for peripheral pulmonary lesions.

Objective: Transbronchial lung cryobiopsy (TBCB) has developed rapidly and has become one of the research hotspots of lung biopsy technology. The present study sought to evaluate the efficacy of TBCB guided by radial-probe EBUS (RP-EBUS) and a guide sheath (GS) without fluoroscopy for peripheral pulmonary lesions.

Methods: In this retrospective study, McNemar's test was used in order to compare TBCB and transbronchial forceps biopsy (TBFB) in terms of diagnostic performance.

An Innovative Method: Predicting the Visibility of Radial Endobronchial Ultrasound for Peripheral Pulmonary Nodules by Virtual Bronchoscopic Navigation.

The diagnosis of peripheral pulmonary nodules (PPNs) still is the key and difficult point. Previous studies have demonstrated that the diagnostic yield of radial endobronchial ultrasound (rEBUS) visible nodules is significantly higher than that of invisible nodules. The traditional method of predicting the rEBUS-visibility of nodules is based on the CT-bronchus signs, but its effectiveness may be unsatisfactory.

The usefulness of liquid-based cytology of bronchoalveolar lavage fluid combined with bronchial brush specimens in lung cancer diagnosis.

Objective: To explore the diagnostic value of liquid-based cytology (LBC) of bronchoalveolar lavage fluid (BALF) combined with bronchial brushing (BB).

Methods: One hundred patients with pulmonary masses or nodules found by chest computed tomography (CT) or X-ray before bronchoscopy or other diagnostic biopsy examinations were selected consecutively for this retrospective study. BALF and BB were performed for all patients.

Study on the effects of combined tea drinking and mental activity after dinner on smokers in China.

Introduction: Cigarette and tobacco use is a leading cause of chronic obstructive pulmonary disease, lung cancer, and other malignant tumors. In China, people prefer to engage in mental activities (gambling, overtime work, playing video games, or other mental activities) on the weekends or during spare time, especially in the evening before they prepare for bed. In China, smokers frequently consume tea while smoking.

Clinical features and nasal inflammation in asthma and allergic rhinitis.

Asthma and allergic rhinitis (AR) are widely considered to be the most common chronic inflammatory disorders. This study was performed to investigate the clinical features, disease severity, and upper airway inflammation among patients with asthma, AR, and asthma comorbid AR. Blood and nasal lavage fluid samples were collected from patients with isolated asthma (n = 23), isolated AR (n = 22), and asthma comorbid AR (n = 22).

Nasal Bacterial Microbiome Differs Between Healthy Controls and Those With Asthma and Allergic Rhinitis.

Perturbation of the microbiome has numerous associations with the phenotypes and progression in chronic airways disease. However, the differences in the nasal microbiome in asthma and allergic rhinitis (AR) have not been defined. We examined whether the nasal microbiome would vary among different comorbidities in asthma and AR and that those differences may be associated with the severity of asthma.

Do nicotine dependence influencing and non-influencing behaviors have an association with high nicotine dependence in smokers?

Introduction: Nicotine dependence (ND) is a maladaptive pattern of tobacco smoking with withdrawal symptoms similar to other drug addictive disorders. It is very common in clinical practice that smokers always have different degrees of nicotine dependence with the same amount of tobacco consumption. Behaviors may influence daily cigarette consumption or smoking status.

Mental activities after dinner increase cigarettes consumption.

Tobacco smoking is the main risk factor for many diseases such as chronic obstructive pulmonary disease as well as lung cancer and cigarettes. Smokers usually keep continuing to smoke during their mental activities in the evening between dinner and sleep time on work days. So it is critical to elucidate the relationship between cigarettes daily consumption and mental activities after dinner.

Diagnostic role of liquid-based cytology of bronchial lavage fluid in addition to bronchial brushing specimens in lung cancer.

Background: Liquid-based cytology (LBC) tests, including the liquid-based thin layer method, have demonstrated the highest potential for reducing false-negatives and improving sample quality.

Method: This study aimed to evaluate the diagnostic role of LBC of bronchial brushing specimens in lung cancer. A total of 249 patients were analyzed in our study, involving 155 patients with combined bronchial brushing and bronchoalveolar lavage (BAL) and 94 patients with BAL alone.

[Epithelium constitution for esophageal tissue engineering using electrospinning technology].

The basement membrane (BM) is crucial in regulating the physical and biological activities of esophageal epithelial cells which attach to the underlying BM. In order to simulate the natural construction of BM, we prepared the fibrous scaffolds using biodegradable polylactide (PLA) and silk fibroin (SF) as the materials via electrospinning technology. BM's proteins containing collagen (IV), laminin, entactin and proteoglycan were extracted from porcine esophagus and coated on the eletrospun fibers.

Progress on materials and scaffold fabrications applied to esophageal tissue engineering.

The mortality rate from esophageal disease like atresia, carcinoma, tracheoesophageal fistula, etc. is increasing rapidly all over the world. Traditional therapies such as surgery, radiotherapy or chemotherapy have been met with very limited success resulting in reduced survival rate and quality of patients' life.
