NCT04233762
The study aim is to investigate if changes in sex hormones during the menstrual cycle affects cough sensitivity in females and males with mild allergic asthma. Female subjects will be grouped according to natural cycle, or taking oral contraceptives. Male subjects will act as the control group.
NCT06288984
Impaired respiratory function may occur after brain injury, and will progress to restricted respiratory dysfunction without early intervention. At present, there is a lack of effective treatment options for respiratory dysfunction. Repetitive Transcranial Magnetic Stimulation(rTMS) is a non-invasive, painless and non-invasive neuroregulatory technique. In healthy people, rTMS applied to the respiratory motor cortex induces a contralateral respiratory muscle response. However, whether rTMS can improve respiratory function in patients with brain injury remains unclear. gut microbiota can affect muscle function and mass, and animal experiments have shown that probiotics can increase skeletal muscle mass and grip strength in mice. On the other hand, studies have found that rTMS can improve the nutritional status of patients with vegetative state by regulating the structure of gut microbiota. However, it remains unclear whether rTMS can improve respiratory muscle function in patients with brain injury by regulating gut microbiota. Therefore, the investigators intend to apply rTMS to the respiratory motor cortex to observe whether rTMS can improve respiratory function and reduce the incidence of pneumonia in patients with brain injury, and to observe the role of gut microbiota in this process.
