Recently, the integration of biomechanics and mechanobiology has introduced mechanical factors into skin disease research. The interaction between mechanical factors and skin's physiological and pathological changes has gradually been transformed in clinical diagnosis and treatment. The two emerging fields, mechanodiagnostics and mechanotherapy, have been developed to address clinical needs. However, clinicians often lack a comprehensive understanding of skin mechanical characteristics and the mechanobiological mechanisms in dermatology. Thus, we propose the concept of \"skin mechanomedicine\". By summarizing relevant research at home and abroad, this paper systematically elucidates the multiscale mechanical characteristics of skin diseases and their impact on biological behavior from four perspectives: skin biomechanics, skin mechanobiology, skin mechanodiagnostics, and skin mechanotherapy. Meanwhile, in-depth exploration was conducted on the potential application of mechanical factors in the diagnosis and treatment of skin diseases, aiming to provide new research perspectives and solutions for the diagnosis and treatment of skin diseases.</p>","PeriodicalId":24023,"journal":{"name":"Zhonghua yi xue za zhi","volume":"105 7","pages":"489-496"},"PeriodicalIF":0.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143433967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The progress in molecular diagnostic technology has effectively improved the diagnostic rate of hereditary hearing loss. Moreover, the findings of population-based molecular epidemiological studies on hearing loss provide theoretical support for the implementation of carrier screening, which aims to identify high-risk families that may give birth to deaf children, and thus lay the foundation for the large-scale prevention of hereditary hearing loss. In view of the lack of unified normative documents on the prevention of hereditary hearing loss in clinical application, a multidisciplinary team of experts consulted the latest evidence-based medicine at home and abroad, and has reached a consensus on the applicable population, strategy, technology, prevention period selection, and clinical process for the pre-pregnancy/prenatal prevention of hereditary hearing loss. The goal is to provide a reference for the clinical standardization implementation of hereditary hearing loss prevention and insight for the research and development of prevention technologies.</p>","PeriodicalId":24023,"journal":{"name":"Zhonghua yi xue za zhi","volume":"105 6","pages":"428-439"},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143411153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
