摘要:

背景:质粒载体因其较好的生物安全性和较高的体内维持时间,被广泛应用于基因治疗研究领域。
目的:观察携带肝细胞生长因子基因重组质粒pUDKH在糖尿病后肢缺血模型大鼠股动脉周围骨骼肌多点注射15 d后骨骼肌组织的病理学变化。
方法:利用STZ制备SD大鼠糖尿病模型。随机分为3组,建模后24 h内高浓度组注射pUDKH 200 μg/只,低浓度组注射pUDKH 100 μg/只,对照组注射等体积医用注射用水。15 d后,取大鼠的骨骼肌组织进行病理学观察。
结果与结论:对照组肌浆萎缩变性,纤维化增生并透明变性,浆细胞浸润变性,肌间隙变宽,有局灶性脓肿形成;pUDKH治疗后有丰富的微血管形成,高浓度组肌纤维横纹较低浓度组保持完整。提示携载肝细胞生长因子基因质粒pUDKH对糖尿病大鼠肢端缺血有治疗作用。

Abstract:

BACKGROUND: At present, plasmid vectors are widely used in gene therapy based on their better bio-security and a longer duration in vivo.
OBJECTIVE: To investigate the histological changes of ischemic skeletal muscle of the hind limbs in diabetic rats after multi-point injection of recombinant plasmids carrying hepatocyte growth factors (pUDKH) into muscles around the femoral arteries for 15 days.
METHODS: Streptozotocin was used to establish diabetes model in Sprague-Dawley rats, and then the rats were divided into three groups randomly. After 24 hours of modeling, rats in the high dosage group were injected with pUDKH at 200 μg for each, those in the low dosage group were injected with pUDKH at 100 μg for each, and those in the control group were treated with medical water for injection at the same volume. Skeletal muscles of the rats were removed for pathological observation at 15 days.
RESULTS AND CONCLUSION: Sarcoplasmic atrophy and degeneration, fibrotic hyperplasia and hyalinization, invasive degeneration of plasma cells, widened muscle space, and focal abscess could be seen in the control group. Plentiful capillaries were formed after the treatment by pUDKH, and stripes of muscle fibers were well kept in the high dosage group compared with the low dosage group. It is indicated that pUDKH carrying hepatocyte growth factors has the therapeutic effects on Limb ischemia of diabetic rats.
