Abstract:

BACKGROUND: Previous studies have confirmed that Longbie capsule or bone marrow mesenchymal stem cells alone have a certain therapeutic effect on knee osteoarthritis.
OBJECTIVE: To observe whether Longbie capsule combined with bone marrow mesenchymal stem cell transplantation is better than the single use in the treatment of knee osteoarthritis.
METHODS: Ninety-six adult male Sprague-Dawley rats were randomly divided into four groups: model group, drug group, stem cell group and drug+stem cell group, with 24 rats in each group. Papain was injected into the knee joint cavity of each rat to duplicate the osteoarthritis model. On the 3rd day after modeling, 0.1 mL of bone marrow mesenchymal stem cell suspension was injected into the knee joint cavity of the rats in the stem cell group, once a week; the water solution of Longbie capsule, 0.937 5 g/kg, was intragastrically injected into the rats in the drug group, twice a week; and the above-mentioned treatments were both performed in the drug+stem cell group. The treatment in each group lasted for 4 weeks. The levels of serum interleukin-1β and interleukin-6 were measured using ELISA before modeling, 3 days after modeling and 4 weeks after administration. Four weeks after administration, the cartilage samples were taken from the right knee joint of each rat for pathological observation with hematoxylin-eosin staining, and for detecting the expressions of collagen type II, Hur, XIAP protein and mRNA using RT-PCR and western blot, respectively. 
RESULTS AND CONCLUSION: On the 3rd day after modeling, the levels of interleukin-1β and interleukin-6 in each group were significantly higher than those before modeling. After 4 weeks of administration, the levels of interleukin-1β in the model group were significantly higher than those in the other three groups (P < 0.05); and the levels of interleukin-1β and interleukin-6 in the drug group and stem cell group were significantly higher than those in the drug+stem cell group (P < 0.05). (2) The surface of articular cartilage tissue in the model group was rough and severely damaged, there were many joint fissures, and the chondrocytes were aggregated and distributed in disorder. The damaged cartilage tissues were partially repaired in the drug group and stem cell group, with the smoother surface of cartilage tissue and fewer joint fissures than the model group, and there were also increased and evenly distributed chondrocytes in the former two groups. The surface of articular cartilage in the drug+stem cell group was smooth, and the chondrocytes were regular and uniformly arranged without joint fissures. (3) The expression of type II collagen, Hur, XIAP protein (or gene) in the model group was lower than that in the other three groups (P < 0.05), and the expression of type II collagen, Hur, and XIAP protein (or gene) in the drug group and stem cell group was lower than that in the drug+stem cell group (P < 0.05). These results indicate that Longbie capsule combined with bone marrow mesenchymal stem cell transplantation is superior to Longbie capsule or bone marrow mesenchymal stem cell transplantation used alone in the treatment of knee osteoarthritis.
