Abstract:

BACKGROUND: Cell transplantation becomes a new approach for treatment of cerebral infarction. In recent years, bone marrow mesenchymal stem cells (BMSCs) have become an important kind of seed cells in cell transplantation.
OBJECTIVE: To investigate the effect of fleabane injection combined with BMSC transplantation on S100B protein and superoxide dismutase expression in acute cerebral infarction rats.
METHODS: Animal models of acute cerebral infarction were made in Sprague-Dawley rats using suture method. After successful modeling, 80 model rats were randomly divided into control group, fleabane group, BMSC group and combined group (fleabane combined with BMSC transplantation). Changes of serum S100B protein and serum superoxide dismutase levels were detected using enzyme-linked immunosorbent assay and xanthine oxidase method, respectively, before and after treatment. NIHSS neurological function scores were measured to observe neurological behavior changes in model rats. The infarct volume was measured by TTC staining.
RESULTS AND CONCLUSION: At 36, 7, 14 days after treatment, S100B protein levels in the fleabane group and BMSC group were significantly lower than that in the control group, but higher than that in the combined group (P < 
0.05); serum superoxide dismutase levels in the fleabane group and BMSC group were significantly higher than that in the control group, but lower than that in the combined group (P < 0.05). At 1, 2, 3 weeks after treatment, NIHSS neurological function scores were ranked as follows: combined group < fleabane group and BMSC group < control group, and there was a significant difference between groups (P < 0.05). At 2 weeks after treatment, the infarct volume in the fleabane group and BMSC group was higher than that in the combined group but lower than that in the control group (P < 0.05). These findings indicate that fleabane combined with BMSC transplantation can inhibit the expression of S100B protein in rats with acute cerebral infarction, and promote the activity of superoxide dismutase, thereby playing a neuroprotective role.
