Purpose: Nitric oxide (NO) is a potential marker in the diagnosis and monitoring of treatment for the management of patients with allergic rhinitis (AR). The study aimed to determine the value of nasal fractional exhaled nitric oxide (FeNO) in the diagnosis and treatment response of AR patients.
Methods: The participants were divided into control and allergic rhinitis groups based on the clinical symptoms and skin prick tests. The AR group was treated with intranasal corticosteroid after the diagnosis. The nasal fractional exhaled nitric oxide (FENO) levels were compared between control and AR groups. In the AR group, the visual analogue scale (VAS), Nasal Obstruction Symptoms Evaluation (NOSE) questionnaire, and nasal fractional exhaled nitric oxide (FeNO) were assessed pre- and post-treatment.
Results: One hundred ten adults were enrolled. The nasal FeNO level was significantly higher in AR compared to control ( < 0.001). Both the subjective (VAS and NOSE), both ( 0.01) and objective (nasal FeNO, < 0.001) assessments showed significant different pre- and post-treatment. The threshold level of nasal FeNO in the diagnosis of AR was 390.0 ppb (sensitivity of 73% and specificity of 80%) based on the receiver operator characteristic curve.
Conclusion: Nasal FeNO level is significantly higher in AR compared to control group with significant difference pre- and post-treatment. The findings suggest nasal FeNO can serve as an adjunct diagnostic tool together with the monitoring of treatment response in AR.

Intestinal dysmotility is a major complication that significantly impacts the prognosis of acute pancreatitis (AP). The neuronal nitric oxide synthase (nNOS) -expressing neurons within the enteric nervous system promote intestinal relaxation via the release of nitric oxide (NO). As the rate-limiting enzyme of NO synthesis, nNOS directly regulates NO production, thereby modulating intestinal motility.

Background: Studies have described sex differences in childhood asthma, allergy, and atopic dermatitis, but the development and clinical phenotype of these differences remain poorly understood.
Objective: To characterize sex differences in atopic disease throughout childhood and study the potential role of sex-steroid metabolites.
Methods: We examined sex differences in asthma, allergy, and atopic dermatitis using longitudinal generalized estimating equation models in the COPSAC (n=411) and COPSAC (n=700) birth cohorts.

Objective: To assess the production of nitric oxide and endothelin in off-pump coronary artery bypass grafting by comparing two techniques of internal thoracic artery preparation: skeletonized and pedicled without endothoracic fascia.
Methods: In this prospective, randomized clinical study, 40 patients undergoing off-pump coronary artery bypass grafting were randomized according to internal thoracic artery preparation technique into the skeletonized or pedicled (without endothoracic fascia) groups (n=20 each). Endothelial expression of CD31 was evaluated by means of immunohistochemistry and en-face immunofluorescence.

Ethnopharmacological Relevance: Chronic inflammatory pain represents a significant global health burden, seriously affecting the patient's quality of life. Jin-Tian-Ge Capsules (JTG), a substitute for natural tiger bone, has been approved in China for the treatment of osteoporosis, osteoarthritis and rheumatoid arthritis. Clinical observations show that JTG can mitigate chronic pain associated with the above bone-related diseases.

Phagocytosis is mediated mainly by immune cells, such as macrophages, monocytes and neutrophils, that clear large pathogens including bacteria. The small GTP-binding protein Rab5 is crucial for both clathrin-dependent endocytosis and phagocytosis, but the role and mechanism of Rab5 activation during phagocytosis are poorly understood. Here we report that nitric oxide (NO), a novel regulator of Rab5, regulates phagocytosis through S-nitrosylation of Rab5.
