As a high-impact publication indexed in SCI and consistently ranked in the top tiers (Zone 1 or 2) of the Chinese Academy of Sciences journal ranking, the journal is renowned for its rigorous academic standards and significant influence on clinical practice. It publishes a broad spectrum of high-quality original research, comprehensive reviews, clinical guidelines, and evidence-based medicine articles, all of which are subject to stringent peer review to ensure scientific validity and clinical relevance.
