Diagnostic value of IgE, fractional of exhaled nitric oxide, and peripheral blood eosinophils in adult bronchial asthma and their relationship with disease severity.

Objective: To investigate the diagnostic value of immunoglobulin E (IgE), fractional of exhaled nitric oxide (FeNO), and peripheral blood eosinophils (EOS) in adult bronchial asthma and to analyze their relationship with asthma severity.

Methods: A retrospective analysis was conducted on 336 patients diagnosed with bronchial asthma and admitted to Xi'an Fourth Hospital from January 2022 to January 2024, forming the asthma group. Additionally, another 127 healthy subjects were selected as the non-asthmatic control group.

[Study on thermal treatment schedule of leucite microcrystallization to reinforce dental glass ceramics].

Objective: To explore the thermal treatment schedule of leucite microcrystallization to reinforce dental glass ceramics.

Methods: After component analysis and selection, the raw material were treated by different temperature schedules. The products were analyzed by polaring microscope and X-ray diffractometer to determine the appropriate thermal treatment schedule.

Study on some mechanism of leucite microcrystallization to reinforce dental glass ceramics.

Objective: To research the influence of K(2)O composition in the raw material on leucite microcrystallization and to study the effect of leucite content on compressive strength of the dental glass ceramics reinforced by leucite microcrystallization.

Methods: The raw materials with different K(2)O content were treated by a decided thermal treatment system. The products were analyzed by polaring microscope and X-ray diffractometer, and their compressive strength was also tested.
