摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗研究基质金属蛋白酶(matrix metalloproteinase,MMPs)在脑动脉瘤患者中的表达,探讨白藜芦醇对其表达的影响。
〖HTH〗方法〖HTSS〗〖KG*2〗选取体质量250~300 g的成年雄性SD大鼠70只,随机分为对照组、模型组、治疗组3组。将模型组和治疗组建立大鼠肾性高血压模型。治疗组给予白藜芦醇(50 mg/kg)混入饲料喂养;模型组仅给予普通饲料;对照组模拟手术,普通饲料喂养。术后1、2、3个月,模型组和治疗组分别随机抽取10只大鼠,采用酶联免疫吸附测定法检测大鼠血清MMP2、9表达水平。显微镜下仔细观察颅底右侧动脉环及其主要分支。
〖HTH〗结果〖HTSS〗〖KG*2〗3组以上指标组间差异有统计学意义(P<005),而时点间及组间·时点间交互作用差异无统计学意义(P>005)。
〖HTH〗结论〖HTSS〗〖KG*2〗白藜芦醇通过抑制MMP2、9的表达,对脑动脉瘤的发生发展起到预防和延缓作用。

Abstract: [Abstract] Objective〖HTSS〗〓To study the expression of matrix metalloproteinase(MMPs) in patients with cerebral aneurysm and to explore the effect of resveratrol on its expression.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Selected 70 adult male SD rats from 250 to 300 grams, were randomly divided into three groups: control group, model group and treatment group. Model group and treatment group were established to model rat renal hypertension. The treatment group was treated with resveratrol(50 mg/kg) mixed with feed. The model group is only for ordinary feed. The control group simulated operation, normal feed feeding. 1, 2 and 3 months after surgery, 10 rats were randomly selected from the model group and the treatment group, and the serum MMP2 and 9 expression levels were detected by enzyme linked immunosorbent assay method. The right arterial ring and its main branches were examined under the microscope.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The comparison between the three groups and the above groups showed significant difference, which was of statistical significance(P<005), while the difference in interaction between groups and between groups and times were of no statistical significance(P>005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Resveratrol can prevent and delay the occurrence and development of cerebral aneurysms by inhibiting the expression of MMP2 and 9.
