Abstract:

BACKGROUND: At present, a great quantity of research has shown the effectiveness of traditional Chinese medicine and bone marrow mesenchymal stem cells for vascular restenosis. However, studies concerning their combined application to restenosis after percutaneous transluminal angioplasty with diabetes mellitus are presently lacking.
OBJECTIVE: To observe the effects of combined application of bone marrow mesenchymal stem cells and benefiting-Qi nourishing-Yin and dissolving-congestion prescription on restenosis after percutaneous transluminal angioplasty in dogs with diabetes mellitus.
METHODS: A dog model of vascular restenosis with diabetes mellitus was established by balloon injury of femoral artery and intravenous injection of alloxan. After successful model induction, 22 dog models were randomly divided into three groups: model group (n=6), treatment with Chinese medicine (n=8), and combined treatment with bone marrow mesenchymal stem cells and Chinese medicine (n=8). Serum vascular endothelial growth factor levels were measured using enzyme-linked immunosorbent assay preoperatively and at 1, 2, 4 and 8 weeks postoperation. Samples of vessels were taken to conduct pathomorphological observation and quantitative analysis of proliferation degree. Tissues, including heart, liver, kidney and pancreatic gland, were collected to evaluate the safety of stem cell transplantation using hematoxylin-eosin staining at 8 weeks postoperation.
RESULTS AND CONCLUSION: Serum vascular endothelial growth factor levels began to increase at 1 week postoperation in the Chinese medicine group and combined treatment group, at 4 weeks postoperation in the model group compared with preoperation (P < 0.05). At all time points, serum vascular endothelial growth factor levels were highest in the combined treatment group, but lowest in the model group (P < 0.05). Quantitative analysis of vascular proliferation demonstrated that at 8 weeks postoperation, new intimal area, new intimal/medial areas and stenosis rate were highest in the model group, but lowest in the combined treatment group at 8 weeks postoperation (P < 0.05). Safety assessment of stem cell transplantation showed morphological structures of the heart, liver, kidneys and pancreas were normal, no necrosis. In a word, the effects of the combined application of bone marrow mesenchymal stem cells and benefiting-Qi nourishing-Yin and dissolving-congestion prescription were much pronounced in preventing restenosis after percutaneous transluminal angioplasty in dogs with diabetes mellitus rather than single therapy of Chinese medicine. It is a safe and effective treatment to prevent vascular restenosis after percutaneous transluminal angioplasty in dogs with diabetes mellitus.
