Risk Factors for Severe Allergic Rhinitis and the Association with Serum-Specific Immunoglobulin E Levels: A Study in Guangzhou, China.

Introduction: The meticulous management of risk factors is paramount in the effective control of allergic rhinitis (AR), playing a significant role in diminishing both the direct medical expenditures and the indirect economic impacts associated with the condition. Presently, there is a notable deficiency in research concerning the risk factors for severe AR, as well as the correlation between serum allergen-specific immunoglobulin E (sIgE) levels and the severity of AR symptoms.

Methods: The study utilized data from a cross-sectional epidemiological survey conducted in Guangzhou, China, from April 2023 to March 2024, involved 638 AR patients.

[Expert consensus on the diagnosis and treatment of respiratory diseases exacerbated by nonsteroidal anti-inflammatory drugs （2024, Chengdu）].

Non-steroidal anti-inflammatory drugs-exacerbated respiratory disease （N-ERD） is a chronic respiratory disease characterized by eosinophilic inflammation, featuring chronic rhinosinusitis （CRS）, asthma, and intolerance to cyclooxygenase 1 （COX-1） inhibitors. The use of these medications can lead to an acute worsening of rhinitis and asthma symptoms. This condition has not yet received sufficient attention in China, with a high rate of misdiagnosis and a lack of related research.

Chinese Expert Consensus on the Use of Biologics in Patients with Chronic Rhinosinusitis (2022, Zhuhai).

Background: Chronic rhinosinusitis (CRS) is a common inflammatory disease in otolaryngology, mainly manifested as nasal congestion, nasal discharge, facial pain/pressure, and smell disorder. CRS with nasal polyps (CRSwNP), an important phenotype of CRS, has a high recurrence rate even after receiving corticosteroids and/or functional endoscopic sinus surgery. In recent years, clinicians have focused on the application of biological agents in CRSwNP.

Nrg1/ErbB2 regulates differentiation and apoptosis of neural stem cells in the cochlear nucleus through PI3K/Akt pathway.

Sensorineural hearing loss (SNHL) is a common causes of disability. Neural stem cells (NSCs) from the cochlear nuclei have been considered to be a potential direction for the treatment of SNHL. Neuregulin 1 (NRG1)/ErbB2 signaling displays an essential role in nervous system development.

Development and external validation of a nomogram to predict the risk of Upper gastrointestinal precancerous lesions in a non-high-incidence area.

Background: Upper gastrointestinal precancerous lesions (UGPL) is the major preventable disease in non-high-incidence area. A prognostic nomogram was constructed to predict and identity susceptible population of UGPL before endoscope screening.

Methods: We recruited 300 ,016 eligible participants for upper gastrointestinal cancer (UGC) screening aged 40-74 years from two cities in Hunan province from 2012 to 2019.

MicroRNA-485-5p suppresses cell proliferation and invasion in hepatocellular carcinoma by targeting stanniocalcin 2.

Increasing evidences indicate that dys-regulation of MicroRNAs contributes to hepatocellular carcinoma. However, the roles of miR-485-5p in HCC are still largely unexplored. In the present study, our quantitative real-time PCR analysis found that miR-485-5p was significantly down-regulated in 50 pairs of human HCC tissues.

The comparison of sensitivity of motion sickness between retinal degeneration fast mice and normal mice.

Recent studies report that a conflict between information from the visual system and vestibular system is one of the main reasons for induction of motion sickness (MS). We may be able to clarify the integration mechanism of visual and vestibular information using an animal model with a visual defect, the retinal degeneration fast (rdf) mouse, and the role of vestibular information in the pathogenesis of MS. The rdf mice and wild-type Kunming mice were subjected to rotary stimulation to induce MS.

Publications about hearing in otorhinolaryngology journals from chinese authors: a 11-year survey of the literature.

Hearing loss is a leading cause of disability in China. However, the research status in the field of hearing among Chinese individuals in the three major regions of China: Mainland (ML), Hong Kong (HK) and Taiwan (TW), are unknown. The output of hearing articles published in international otorhinolaryngology journals from these three regions were compared in this study.

Determining leak locations during transnasal endoscopic repair of cerebrospinal fluid rhinorrhea.

Objective: For transnasal endoscopic repair procedures to be successful, it is critical to identify leak locations during surgery. We aim to evaluate different methods to more accurately detect leak locations during the endoscopic repair of cerebrospinal fluid rhinorrhea.

Materials And Methods: We performed a retrospective chart review of 39 cases undergoing endoscopic repair of cerebrospinal fluid rhinorrhea.

Primary myxofibrosarcoma of the parotid: case report.

Background: Myxofibrosarcoma is common in the extremities of elderly people and is characterized by a high frequency of local recurrence.

Case Presentation: We report a 37 year old female who presented with a 4-month history of facial pain and a 3-month history of painful progressive swelling in the preauricular area. She underwent a total parotidectomy.

[Immunogenicity of multi-epitopes gene of major outer membrane protein of Chlamydia trachomatis].

Objective: To construct a recombinant eukaryotic expression plasmid pcDNA3.1-Ct MOMP168 including Ct MOMP multi-epitopes gene, and evaluate the Ct MOMP-specific humoral and cellular immune response induced by pcDNA3.1-Ct MOMP168 in BALB/c mice.

[An effective combined therapy for simple premature ejaculation].

Objective: To observe the clinical effect of a combined therapy in the treatment of simple premature ejaculation.

Methods: A total number of 110 patients with simple premature ejaculation were divided into a control group (n = 50), given oral hydrochloric acid sertraline only, and a combined therapy group (n = 60), treated by oral administration of hydrochloric acid sertraline, local inunction of a traditional Chinese medicine and guidance in sexual psychology and knowledge. At the end of a 4-week treatment and 4 weeks after the drug withdrawal, the therapeutic effects were evaluated by ejaculation latency and satisfaction with sexual life.

Development of self-microemulsifying drug delivery systems for oral bioavailability enhancement of alpha-Asarone in beagle dogs.

A self-microemulsifying drug delivery system (SMEDDS) for enhancement of oral absorption of a poor water-soluble drug, alpha-Asarone (ARE), is reported. Solubility of ARE was determined in various vehicles. SMEDDS consisted of a mixture of oils, surfactants, and cosurfactants that were emulsified in an aqueous medium under the gentle agitation and digestive motility.

Anticancer drug resistance of HeLa cells transfected with rat glutathione S-transferase pi gene.

Objective: To establish a cytologic expressing system of rat glutathione S-transferase pi (GST-pi) cDNA for detecting the resistance of HeLa cells to anticancer drugs.

Methods: The assessment was made with various anticancer drugs (adriamycin, mitomycin, cisplatinum and vincristine) that showed different cytotoxicities in transfectant HeLa cells with pSV-GT containing rat GST-pi cDNA (HeLa/pSV-GT) or control pSV-neo (HeLa/pSV-neo). Expression levels of GST-pi mRNA in HeLa/pSV-GT and HeLa/pSV-neo were measured by in situ hybridization using Digoxin-labelled cDNA probe.
