Background: Artemisia pollen is the most prevalent outdoor aeroallergen causing respiratory allergies in Beijing, China. Pollen allergen concentrations have a direct impact on the quality of life of those suffering from allergies. Artemisia pollen deposition grading predictions can provide early warning for the protection and treatment of patients as well as provide a scientific basis for allergen specific clinical immunotherapy.
Objective: To develop a model of Artemisia pollen grading to predict development in patients with pollen allergy.
Methods: Artemisia pollen data from four pollen monitoring stations in Beijing as well as the number of Artemisia pollen allergen serum specific immunoglobulin E positive cases in Beijing Tongren Hospital from 2014 to 2016 were used to develop a statistical model of pollen deposition and provide optimised threshold values.
Results: A logarithmic correlation existed between the number of patients with Artemisia pollen allergy and Artemisia pollen deposition, and the average pollen deposition for three consecutive days was most correlated with the number of allergic patients. Based on the threshold of the number of patients and the characteristics of Artemisia pollen, a five-stage pollen deposition grading model was developed to predict the degree of pollen allergy.
Conclusions: Graded prediction of pollen deposition may help pollen allergic populations benefit from preventive interventions before onset.

Background: Thunderstorm Asthma (TA) events are observed worldwide, but the precise triggering mechanisms remain elusive.
Objective: This study aims to outline the environmental patterns associated with TA events in China.
Methods: Environmental data was collected from Chinese cities that have experienced TA events, focusing on meteorological conditions in the seven days preceding the thunderstorms.

Pollen-food allergy syndrome is an IgE-mediated allergic reaction arising from cross-reactive homologous allergens found in both food and pollen. Allergens, such as pathogenesis-related protein class 10 and profilin, usually trigger oropharyngeal itching and numbness in patients, whereas lipid transfer proteins tend to induce anaphylaxis. This article presents a case study of an individual with Artemisia pollen allergy who experienced anaphylaxis after consuming red fruit ginseng, a perennial herb belonging to the Campanulaceae family.

Background: Pollen is the most common outdoor allergen that causes allergic rhinitis and asthma, which seriously affects patient quality of life and extensive cross-reactivity occurs between pollen allergens.
Methods: The study enrolled 84 patients with respiratory allergies and at least one pollen allergy who visited the clinic. Specific-IgE was detected via immunoblotting in the sera of patients with positive respiratory allergies to pollen.

Purpose: This study aimed to investigate the efficacy and safety of coseasonal initiation of Artemisia annua sublingual immunotherapy (SLIT) for children and adult patients with allergic rhinoconjunctivitis (ARC).
Methods: A total of 50 patients (aged 4-60 years) with ARC who visited hospital from July to September 2022 were enrolled and randomly divided into the SLIT (n = 25) and control group (n = 25). Patients in SLIT group received Artemisia annua SLIT and patients in control group only received symptomatic medication.
