Characteristics of LKDS and PBSS of KOA Based on the Enhancement of Inflammatory Response by TGF-β/Smad Pathway Inhibited

1. Through research and analysis, the levels of upstream and downstream factors related to TGF-β/Smad signaling pathway and inflammatory response factor related factors in serum, blood cells, articular fluid, urine, tongue covering and discarded tissues after surgery of patients with LKD syndrome and PBS syndrome of knee osteoarthritis were obtained, and the syndrome characteristics were further obtained.
2. Through research and analysis, the index levels of multiple omics detection in serum, blood cells, joint fluid, urine, tongue coating and discarded tissues of patients with LKD syndrome and PBS syndrome of knee osteoarthritis were obtained, and the syndrome characteristics were further obtained.
3. The severity of syndrome was quantified by syndrome score scale and the correlation between the above results and the syndrome score of patients with knee osteoarthritis with LKD syndrome and PBS syndrome was studied in combination with imaging characteristics.
4. To establish a "disease and syndrome cell model" and test relevant indicators to support the above research.
5. Through the analysis of the above research results, the possible mechanism is analyzed to provide an objective basis for the biological basis of the syndrome and relevant evidence for the clinical diagnosis and treatment of knee osteoarthritis with traditional Chinese medicine.
