Laboratory test (any item meets): neutrophil absolute number < 1.0 × 10^9 / L, platelet count < 50 × 10^9 / L, serum albumin < 30g / L, serum creatinine > upper limit of 1.2 times normal value range, total bilirubin、alanine aminotransferase、aspartate aminotransferase > upper limit of 2 times of normal value range.
5. The subject has diseases or symptoms may affect VAS, WOMAC and so on.
6. The subject has serious and poorly controlled concomitant diseases, such as (but not limited to) nervous system, cardiovascular, liver, kidney, gastrointestinal and endocrine diseases, which may prevent the subjects from participating in the study according to the judgment of the researchers.
