OBJECTIVETo explore the effect of Bushen Gujin Recipe (BGR) on serum and synovial expression of interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α) in knee osteoarthritis (KOA) model rabbits.

METHODSTotally 36 8-month-old healthy male New Zealand white rabbits were randomly divided into 4 groups, i.e., the normal control group, the model group, the Western medicine group (Meloxicam, at the daily dose of 6 mg/kg), and the TCM group (BGR, at the daily dose of 53 g/kg), 9 in each group. Modeling was performed in all rabbits except those in the normal control group by using Hulth A method. All medication was performed for 8 consecutive weeks. Contents of IL-1 and TNF-α were detected using ELISA from serum, partial synovial tissue of the front knee joint, cartilage and subchondral bone of the medial femoral condyle.

RESULTSThe joint space became narrowed in the Western medicine group, ranging between the model group and the TCM group. The articular surface was rough with obvious osteophytes. The joint space was slightly narrower in the TCM group; the articular surface was slightly rough with mild osteophytes. Compared with the normal control group, contents of IL-1 and TNF-α in serum and synovial increased in the model group (P < 0.01). Compared with the model group, contents of IL-1 and TNF-α in serum and the synovial fluid decreased in the two treatment groups (P < 0.01). There was no statistical difference in contents of IL-1 and TNF-α between the Western medicine group and the TCM group.

CONCLUSIONBGR promoted the synthesis of cartilage matrix and carti- lage repair through inhibiting the secretion of IL-1 and TNF-α, and prolonging cartilage degeneration.

OBJECTIVETo evaluate the safety and the clinical value of external use of jiuyi Powder (JP) in treating plasma cell mastitis using partial least-squares discriminant analysis (PLSDA).

METHODSTotally 50 patients with plasma cell mastitis treated by external use of JP were observed and biochemical examinations of blood and urine detected before application, at day 4 after application, at day 1 and 14 after discontinuation. Blood mercury and urinary mercury were detected before application, at day 1, 4, and 7 after application, at day 1 and 14 after discontinuation. Urinary mercury was also detected at 28 after discontinuation and 3 months after discontinuation. The information of wound, days of external application and the total dosage of external application were recorded before application, at day 1, 4, and 7 after application, as well as at day 1 after discontinuation. Then a discriminant model covering potential safety factors was set up by PLSDA after screening safety indices with important effects. The applicability of the model was assessed using area under ROC curve. Potential safety factors were assessed using variable importance in the projection (VIP).

RESULTSUrinary β2-microglobulin (β2-MG), urinary N-acetyl-β-D-glucosaminidase (NAG), 24 h urinary protein, and urinary α1-microglobulin (α1-MG) were greatly affected by external use of JP in treating plasma cell mastitis. The accuracy rate of PLSDA discriminate model was 74. 00%. The sensitivity, specificity, and the area under ROC curve was 0. 7826, 0. 7037, and 0. 8084, respectively. Three factors with greater effect on the potential safety were screened as follows: pre-application volume of the sore cavity, days of external application, and the total dosage of external application.

CONCLUSIONSPLSDA method could be used in analyzing bioinformation of clinical Chinese medicine. Urinary β2-MG and urinary NAG were two main safety monitoring indices. Days of external application and the total dosage of external application were main factors influencing blood mercury and urine mercury. A safety classification simulation model of treating plasma cell mastitis by external therapy of JP was established by the two factors, which could be used to assess the safety of external application of JP to some extent.
