Central post-stroke pain (CPSP), a neuropathic pain syndrome occurring after a cerebrovascular accident, is characterized by pain or paraesthesia in the part of the body dominated by the area of the brain where blood vessels are injured. CPSP patients are often accompanied by anxiety, depression and other emotional disorders, which have a serious negative impact on patients' quality of life. However, the pathogenesis of CPSP has not been fully elucidated, the clinical diagnosis rate is not high, and the commonly used treatment methods are not effective. This article reviews the clinical features, epidemiology, pathogenesis and treatment of CPSP in order to provide reference for the elucidation of CPSP mechanism and effective treatment.

Epidural labor analgesia aims to provide effective medical services to alleviate labor pain in parturients, while adhering to the principles of voluntary participation and clinical safety. In 2018, Peking Union Medical College Hospital(PUMCH)became one of the first pilot units for labor analgesia in China, and has achieved satisfactory results in high-quality development of labor analgesia. This article mainly introduces the achievements and experience of labor analgesia at PUMCH, including: (1) prioritizing maternal and infant safety, arranging personnel rationally, and developing standardized treatment processes through multidisciplinary collaboration to ensure safe and comfortable childbirth; (2) leveraging the hospital's comprehensive capabilities in emergency treatment, and improving collaborative rescue plans for critically ill parturients and newborns; (3) implementing advanced teaching methods to effectively train and conduct simulated drills for labor analgesia and rescue of critically ill parturients; (4) conducting patient education and informative lectures to help parturients acquire a scientific understanding of labor analgesia. We hope that this experience can provide reference and inspiration for other hospitals.
