Circular RNAs: Functions and mechanisms in nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is a malignant epithelial tumor of the nasopharyngeal mucosa with a high incidence rate in southern China and Southeast Asia and an evident ethnic and geographical distribution. Circular RNAs (circRNAs) are single-stranded noncoding RNAs with covalent, closed-loop structures. They are characterized by high stability and abundance, are evolutionarily conserved, and exhibit tissue/developmental stage specificity.

Innovative application of internal carotid artery embolization in salvage endoscopic nasopharyngectomy for recurrent nasopharyngeal carcinoma: A case-matched comparison.

Background: The efficacy and safety of internal carotid artery (ICA) embolization as a treatment strategy in recurrent nasopharyngeal carcinoma (rNPC) patients with tumors invading the ICA remain unclear.

Methods: We enrolled all rNPC patients with tumors invading the ICA, who underwent salvage endoscopic surgery. Using propensity scores to adjust for specific potential prognostic factors, a well-balanced cohort of 42 patients with limited rNPC was formed by matching each patient who underwent ICA embolization (study group) with one who did not (control group).

Chinese Society of Allergy Guidelines for Diagnosis and Treatment of Allergic Rhinitis.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2-3 decades in developing countries including China, with the prevalence of AR varying widely in these countries.

Chinese Guideline on allergen immunotherapy for allergic rhinitis.

The present document is based on a consensus reached by a panel of experts from Chinese Society of Allergy (CSA) and Chinese Allergic Rhinitis Collaborative Research Group (C2AR2G). Allergen immunotherapy (AIT), has increasingly been used as a treatment for allergic rhinitis (AR) globally, as it has been shown to provide a long-term effect in improving nasal and ocular symptoms, reducing medication need, and improving quality of life. AIT is currently the only curative intervention that can potentially modify the immune system in individuals suffering from AR and prevent the development of new sensitization and the progression of disease from AR to asthma.
