Bronchial asthma (referred to as asthma for short) is a chronic airway inflammatory disease involving various cells and cell components. The clinical manifestations are repeated wheezing, shortness of breath, with or without chest tightness, cough and other symptoms, accompanied by airway hyperresponsiveness and variable airflow obstruction. With the prolongation of the disease course, it may even lead to airway remodeling. Surveys have found that the prevalence of asthma among children aged 0-14 in China is 3.02%, reaching 7.6 million; the prevalence among adults is 4.2%, reaching 45.7 million. Glucocorticoid (ICS) is the preferred anti-inflammatory drug for asthma treatment recommended by authoritative guidelines at home and abroad. Chenkeshu - Fluticasone Propionate Nebuliser Suspension for Inhalation is a new generation of ICS, with higher anti-inflammatory activity and safety. In addition to the treatment of asthma, airway management during the perioperative period is also an important field of application for Chenkeshu.

Used in conjunction with a low-protein diet to prevent and treat damage caused by protein metabolism disorders due to chronic renal insufficiency. It is typically used for patients with a glomerular filtration rate (GFR) below 25 milliliters per minute. A low-protein diet requires adults to limit their daily protein intake to 40 grams or less.

Postoperative pain is the most common and urgent acute nociceptive pain in clinical practice, and it is a problem faced by the majority of surgical patients. Studies show that the incidence of postoperative pain is as high as 82%, and the incidence of pain after discharge is as high as 75%. If postoperative pain is not adequately controlled initially, it can lead to pathological remodeling of the central nervous system, and acute pain may develop into difficult-to-control chronic pain. Postoperative pain can affect various aspects of a patient's health, including endocrine function, cardiac function, pulmonary function, gastrointestinal function, and both peripheral and central systems. Both domestic and international clinical guidelines recommend early treatment of postoperative pain, advocating for multimodal analgesia and emphasizing individualized pain management. Additionally, patients need to adopt continuous, multimodal, and preventive analgesic measures to prevent the formation of a pain-sensitive state. These measures aim to achieve complete, long-lasting, and effective pain relief that covers the entire perioperative period.
