Research on the Extraction of Tongue and Facial Diagnosis Features of Psoriasis Vulgaris in Traditional Chinese Medicine and Its Correlation With Laboratory Indicators

Обзор

Psoriasis Vulgaris is a chronic, inflammatory, and immune-activated skin disease. It is the most common type of psoriasis, accounting for approximately 85-90% of all psoriasis patients. Its clinical features include erythema, papules, covered with varying scales, a long course of disease, and recurrent attacks. According to traditional Chinese medicine, psoriasis is mainly characterized by blood heat syndrome, blood stasis syndrome and blood dryness syndrome, accounting for more than 90% of all syndrome types. The TCM syndrome differentiation and treatment of psoriasis also attach great importance to the transformation and evolution of TCM syndrome types. For instance, the three syndrome types of blood heat syndrome, blood stasis syndrome and blood dryness syndrome are not static and can transform into each other. For example, blood heat syndrome can develop into blood dryness syndrome as the disease progresses, blood dryness syndrome can transform into blood stasis syndrome, and blood stasis syndrome can also transform into blood heat syndrome or blood dryness syndrome. Observation is an important diagnostic method in traditional Chinese medicine. The images of tongue and face diagnosis contain a lot of important clinical information. They can objectively reflect the prosperity and decline of qi and blood in the human body, the nature of diseases, the depth of the lesion location, the prognosis of the disease, and can also reflect the physiological and pathological changes of the body. In recent years, significant progress has been made in the research of digital and intelligent technologies for tongue and facial diagnosis. Introducing objective indicators such as tongue diagnosis, facial diagnosis and pulse diagnosis into the evaluation research of diseases has become a hot topic. This project, by analyzing the clinical tongue and facial image data of patients with psoriasis vulgaris and combining it with clinical laboratory indicators, fuses and analyzes the characteristic parameters of patients' tongue and facial diagnosis with blood biochemical indicators, metabolomics and other data. This is helpful to reveal the disease occurrence pattern of patients with blood stasis type psoriasis and construct a diagnostic model for blood stasis syndrome of psoriasis. At the same time, it provides a powerful decision support tool for clinical practice and also helps deepen our understanding of the complex process of the occurrence of blood stasis type psoriasis, thereby providing a solid scientific basis for formulating precise diagnostic and treatment strategies.
