Lignin is one of the main components in plants, which can transform value-added bioenergy and chemicals. At the same time, due to the close combination of lignin and hemicellulose in the structure, it becomes a barrier for cellulose utilization. Therefore, the effective degradation of lignin is of great significance for the utilization of these resources.

Epigenetic modifications, such as N6-methyladenosine (m6A) modification of mRNA, play important roles in regulating gene expression in multiple physiological and pathological processes. However, the function of m6A modification in AR and the inflammatory response is poorly understood.

Methods: A prospective study was admitted to the children undergoing T&A at our institution between October 2019 and January 2020, specifically focusing on preoperative coagulation function. Within this group, we identified 5 patients exhibiting prolonged APTT and coagulation factor deficiencies, constituting the experimental group, and 10 patients matched by gender and age with normal blood coagulation function were selected as the control group.

To assess the presentation of allergic fungal rhinosinusitis(AFRS) in children and the role of long-term comprehensive therapy of endoscopic surgery combined with drug therapy. The 3 children with AFRS were routinely examined by nasal endoscopy, CT scan, MRI scan and allergen detection before surgery, and mycological and histomathological examination were performed on the secretions in the sinus and the mucosa of the affected sinuses. All the 3 patients underwent endoscopic surgery, preoperative and postoperative treatment with oral and nasal corticosteroid, nasal irrigation, and individualized anti-allergy therapy and immunotherapy.

Objectives: To evaluate the effect of hypothermic saline application for pediatric coblation tonsillectomy on postoperative pain.
Methods: Forty-eight children with adenotonsillar hyperplasia underwent tonsillectomy ± adenoidectomy. 24 children were in the HTS group (which used hypothermic saline as the coblation medium in operation), the other 24 children with the same age were in the control NTS group (who use normothermic saline as the coblation medium).
Background: Epistaxis is a common symptom in children. The effect of air pollution on epistaxis is not yet clear.
Objectives: To explore the characteristics of pediatric epistaxis in Beijing and its correlation with air pollutants.

Objectives: The aim of the study was to investigate upper airway cough syndrome (UACS) in children and to determine alternative methods to explore the relationships among TRPV1, TGF-β2, and UACS.
Methods: In 2012, 104 children with adenoid hypertrophy aged 2-13 years who were admitted to the otolaryngology department, Capital Institute of Pediatrics-affiliated children's hospital, were included in this study. Enzyme-linked immunosorbent assay (ELISA) and immunohistochemical (IHC) studies for TRPV1 and TGF-β2 were performed to understand the relationship between the two inflammatory factors, and the correlations among the indices and UACS.
