What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in VAS pain score from baseline 4 weeks | After treatment.researchers and investigators were assessed by VAS score (0-10cm) for the overall condition of the disease. Participants rated their current state of control from very good to very poor. The researchers rated disease activity status from no active rheumatism to most severe active rheumatism. The score is accurate to one decimal place. | 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in WOMAC scale scores from baseline |  | 4 weeks | 
| Health Measurement Scale (SF-36) |  | 4 weeks | 
| Number of Participants With Metabolic Abnormal Events at All Assessment Time Points. | The participants were tested with blood lipid [liver and kidney function [aspartate aminotransferase(AST), alanine aminotransferase(ALT), Urea(Ur), Crea(Cr)] for regular metabolic function evaluation .The number of participants experiencing metabolic abnormal events have been reported. | 4 weeks |
