Description
技术领域
本发明涉及恒河猴糖尿病肾病模型的制备方法。
背景技术
糖尿病(Diabetes Mellitus,DM)的发病率呈快速增长的趋势。据报道我国现约有9200万DM和1.48亿DM前期患者,成为继美国之后的第二个糖尿病发病大国。随着病情的逐渐发展加重,这些患者中约有30-40%的1型糖尿病患者和约20%的2型糖尿病患者伴随严重的肾功能损害——糖尿病肾病(Diabetic Nephropathy,DN)。
DN是糖尿病患者最严重的慢性并发症之一,也是糖尿病患者最主要的死亡原因。一旦DN患者出现了显著的临床症状,此时可选择的药物较少,且药物的治疗效果较差,病情往往呈进行性发展直至末期肾衰,给患者家庭和社会带来巨大的经济负担。因此深入研究DN的发病机制及早期诊断方法,在此基础上探索延缓或逆转疾病进程的有效措施,是目前医学研究的热点和难点问题。
动物模型是研究人类重大疾病的基础,建立与人类高度近似的DN动物模型,将会在研究其发病机理、早期诊断和干预治疗等方面取得事半功倍的效果。非人灵长类动物作为人类的近亲,在遗传基因方面约96%以上同源,其形态结构、生理机能和生化代谢均同人类非常相似,建立一种非人灵长类动物DN模型对研究DN的发生发展、早期诊断和新药研发等具有重要的科学意义和经济价值。

3.3肾脏B超检查的血流分布和频谱
如图5所示,早期肾血管床阻力增加,从而使肾内血流发生改变,随着病情加重,动脉硬化的血管壁弹性减低,管腔狭窄,外周血管阻力增高,肾血流灌注减少,使肾血流呈低流,高阻状态,其中,B组和C组的的病理改变非常明显,C组最为明显。
3.4肾血流动力学参数和血流灌注系数
如图4所示,与对照组相比,ABC三组血流动力学参数阻力指数(RI)增加,舒张末期最低流速(EDV)降低,血流灌注系数曲线下面积(AUC)降低,C组与对照组的差异最大,B组其次,A组差异最小。

综上,实验组A未出现糖尿病肾病的相关症状,实验组B和C出现了糖尿病肾病的典型临床症状:
1、实验组B和C在第36个月开始出现了微量蛋白尿(MAU)并且随着病程推移有增加趋势;
2、肾组织HE、Masson、PAS染色显示:实验组A无病变,实验组B和C肾脏从第24个月开始出现炎性细胞侵润、系膜细胞增生、基底膜增厚、胶原和糖原的沉积,并且发现实验组C在第42个月出现局部肾小球硬化。同时期肾组织免疫荧光显示实验组BC于正常组和实验A组相比CTGF、eNOS、IL-1、IV型胶原、纤连蛋白(FN)、TGF-β表达增加,并且在实验组C更加显著,同时实验组C还出现MCP1和TNF-α表达;
3、Real-time PCR显示:实验组B和C在第24个月开始出现Smad2和Smad3mRNA表达,实验组C更显著,并且在第42个月出现Smad7和NF-κb mRNA表达增加;
4、肾血管造影显示,实验组B和C的血流灌注系数AUC和流动力学参数阻力指数RI显著增加,舒张末期最低流速EDV降低(P<0.05),动脉硬化的血管壁弹性减低,管腔狭窄,外周血管阻力增高,肾血流灌注减少,使肾血流呈低流、高阻状态;
本发明通过长期控制糖尿病恒河猴的血糖浓度范围为10-20mmol/L,使得糖尿病恒河猴出现肾组织炎性细胞侵润、系膜细胞增生、基底膜增厚、胶原和糖原的沉积、肾脏损伤、微量蛋白尿等糖尿病肾病的典型临床症状,说明本发明恒河猴糖尿病肾病造模成功。
本发明通过长期控制糖尿病恒河猴的血糖浓度范围为10-20mmol/L,结合长期高脂肪摄入的方式,使得糖尿病恒河猴的各种糖尿病肾病典型症状比单独控制血糖的方式更为显著,说明二者联合处理的方式更优。
