摘要:

背景:目前大量研究已经证实了中药制剂、骨髓间充质干细胞在防治血管再狭窄中的有效性,但二者联合应用防治糖尿病下肢动脉介入成形后血管再狭窄的相关研究较少。
目的:观察骨髓间充质干细胞联合益气养阴化瘀中药对犬糖尿病股动脉介入成形后血管再狭窄的影响。
方法:采用四氧嘧啶静脉注射结合球囊损伤建立糖尿病下肢血管再狭窄犬模型,造模成功后将22只犬随机分为3组,即糖尿病模型组(模型组,n=6)、益气养阴化瘀方治疗组(中药组,n=8)及益气养阴化瘀方联合骨髓间充质干细胞治疗组(联合治疗组,n=8)。分别在经皮腔内血管成形前、治疗后1,2,4,8周采用ELISA法检测血清中血管内皮生长因子水平。治疗后8周取股动脉血管标本进行病理血管形态学观察及增生程度的定量分析,并取心肝肾胰腺组织标本行病理切片苏木精-伊红染色评价干细胞静脉移植安全性。
结果与结论:治疗后1周,中药组和联合治疗组血清血管内皮细胞生长因子均开始升高,模型组治疗后4周开始升高(与治疗前比较,P < 0.05)。同期各阶段,血清血管内皮细胞生长因子水平联合治疗组最高,模型组最低(P < 0.05)。血管增生程度定量分析结果显示,治疗后8周新生内膜面积、新生内膜/中膜面积及狭窄率,模型组最高,联合治疗组最低(P < 0.05)。干细胞移植安全性评价结果显示,治疗后8周心肝肾胰腺组织内部结构形态正常,未见组织坏死现象。综上,骨髓间充质干细胞联合益气养阴化瘀方比单纯中药治疗在防治糖尿病下肢动脉介入成形后再狭窄中作用更显著,是一种安全、有效的防治糖尿病下肢动脉介入成形后血管再狭窄发生的手段。

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.
