Quantitative assessment and correlational analysis of subjective and objective indicators in patients with allergic rhinitis.

Background: The diagnosis of allergic rhinitis is mainly based on the typical medical history, clinical manifestations, and corresponding allergen test results of the patients. However, there are often clinical inconsistencies among the 3.

Objective: To study the clinical characteristics of patients with allergic rhinitis from both subjective and objective aspects to determine the correlations between the quantitative assessment outcomes of subjective and objective indicators.

Effect of Blocking the OX40/OX40L Signaling Pathway by siRNA Interference on Animal Experimental Study of Allergic Rhinitis.

Background: The identification of new approaches and intervention targets for the treatment of AR is urgently needed. We aimed to investigate the effect of blocking the OX40/OX40L signaling pathway by small interfering RNA (siRNA) on ovalbumin (OVA)-induced AR in a mouse model.

Methods: After establishment of the AR model, the mice were interfered by siRNA-OX40L (experimental group), siRNA-C (negative control group), or PBS (control group).

Silencing of FANCD2 enhances the radiosensitivity of metastatic cervical lymph node-derived head and neck squamous cell carcinoma HSC-4 cells.

Fanconi anemia complementation group D2 (FANCD2) is involved in the key steps of the Fanconi anemia (FA) pathway, which plays a role in the repair of DNA crosslink damage. However, the role of FANCD2 during radiotherapy for head and neck squamous cell carcinoma (HNSCC) is unclear. In this study, the HNSCC cell line HSC-4 was used.

Rosai-Dorfman disease (RDD) in the paraglottic space: report of a case and review of literature.

Sinus histiocytosis with massive lymphadenopathy is also known as Rosai-Dorfman disease (RDD) and is characterized by painless bilateral cervical lymphadenopathy. In the present case report, a 67-year-old Chinese woman presented with a 3-month history of progressive voice hoarseness, progressive dyspnea on exertion and a foreign body sensation. MRI revealed a lesion involving the right side of the paraglottic space.

Scalp junctional nevus with malignant transformation (melanoma) metastatic to parotid lymph node region, cervical lymph nodes and the back: a case report and review of literature.

Parotid malignancy may occur as a primary neoplasm of the salivary tissue or as metastatic involvement of the parotid lymph nodes. Primary tumors of squamous cell carcinoma and malignant melanoma involving the skin of the head and neck have the potential to spread to lymph nodes of the parotid gland. Metastatic malignant melanoma to the back was exceptionally rare and no such reports have been noted in the literature.

[Role and mechanism of the expression of matrix metalloproteinase 9 and tumor necrosis factor α in upper and lower respiratory tract inflammation in rats].

Objective: To investigate the role and mechanism of matrix metalloproteinase 9 (MMP-9) and tumor necrosis factor α (TNF-α) in the pathogenesis of allergic rhinitis (AR) and asthma(AS).

Methods: The rat models of AR and AS were made by injecting ovalbumin. The infiltration of eosinophils and mast cells were detected by hematoxylin-eosin (HE) staining and toluidine blue staining respectively, and the expression of MMP-9 and TNF-α in nasal mucosa and lung tissue were examined by immunohistochemical staining (SP method).
