文题释义:
脂联素:
为可溶性胶原家族成员之一,其由244个氨基酸的残基组成,其有着降糖、降血脂、增加胰岛素的敏感性及抗动脉粥样硬化的作用。国内外的众多相关研究表明脂联素与胰岛素抵抗、肥胖、2型糖尿病等代谢综合征相关,2型糖尿病患者循环中脂联素水平和脂肪组织中脂联素基因表达均降低。
脂肪干细胞:是近年来从脂肪组织中分离得到的一种具有多向分化潜能的干细胞。主要恢复组织细胞的修复功能,促进细胞的再生,恢复年轻面容的同时,身体功能也得到充分改善,有效改善亚健康、早衰等疾病,由内而外真正的有效抵抗衰老。与骨髓干细胞类似,脂肪干细胞由脂肪组织提取而来,因此来源较其他干细胞更广泛。以往人们认为脂肪是人体肥胖之源,瘦身后抽出的脂肪组织都当成废弃物丢弃,现经由医学专家研究证实,同骨髓中存在造血干细胞一样,脂肪组织中同样含有大量的间质干细胞,这种间质干细胞也具有体外增生及多重分化的潜力。  

 

摘要
背景:
脂联素可以调节机体内的糖和脂代谢,保护机体组织器官,故将其与干细胞移植联合用于治疗肾病综合征。
目的:探讨脂联素联合脂肪干细胞治疗大鼠肾病综合征的影响。
方法:①体外复苏培养大鼠脂肪干细胞,移植前行CM-Dil 标记;②将80只SD大鼠随机分为4组:对照组、肾病综合征模型组、脂肪干细胞移植组和脂联素联合脂肪干细胞移植组,各20只。后3组采用单次尾静脉阿霉素注射(6 mg/kg)构建大鼠肾病综合征的模型,分别经尾静脉注射生理盐水,2×106 L-1脂肪干细胞悬液和2×106 L-1脂肪干细胞悬液+1 μg/kg脂联素,1次/d,连续3 d。
结果与结论:①造模28 d后,与对照组相比,其余3组大鼠的24 h尿蛋白、血胆固醇和尿素氮水平较高,血白蛋白水平较低;与肾病综合征模型组相比,脂肪干细胞移植组大鼠24 h尿蛋白、血胆固醇和尿素氮水平降低,血白蛋白水平升高;与脂肪干细胞移植组相比,脂联素联合脂肪干细胞移植组24 h尿蛋白、血胆固醇和尿素氮水平降低,血白蛋白水平升高;②造模28 d后,肾病综合征模型组大鼠肾组织的病理损伤最为明显,脂肪干细胞移植组大鼠肾组织的病理损伤明显减轻,脂联素联合脂肪干细胞移植组大鼠肾组织的病理损伤明显改善,炎性细胞及水肿均减轻;③肾组织中CM-Dil 阳性细胞:脂联素联合脂肪干细胞移植组最多,脂肪干细胞移植组次之,对照组和肾病综合征模型组未见;④结果提示脂肪干细胞移植对肾病综合征有一定治疗作用,且脂联素可以增强其治疗效果,改善肾功能指标,有效抑制肾组织的病理损伤。

Abstract:

BACKGROUND: Adiponectin can regulate glucose and lipid metabolism in the body and protect body tissues and organs. Therefore, we combine it with stem cell transplantation for the treatment of nephrotic syndrome.
OBJECTIVE: To investigate the therapeutic effect of adiponectin combined with adipose stem cell transplantation in the rats with nephrotic syndrome. 
METHODS: Rat adipose stem cells were resuscitated and cultured in vitro, and labeled using CD-Dil prior to the transplantation. Eighty Sprague-Dawley rats were randomly assigned into a normal control group, a model group, an adipose stem cell transplantation group, and a combined group (adiponectin and adipose stem cell transplantation), with 20 rats in each group. Rats in the normal control group received no treatment. The remaining rats in the latter three groups were given a single intravenous injection of adriamycin (6 mg/kg) to prepare animal models of nephrotic syndrome, followed by a tail vein injection of normal saline, 2×106/L adipose stem cell suspension, and 1 μg/kg adiponectin plus 2×106/L adipose stem cell suspension, respectively. Administration of adiponectin in the combined group was given once a day, for 3 consecutive days.
RESULTS AND CONCLUSION: (1) Compared with the normal control group, higher levels of 24-hour urinary protein, blood cholesterol and urea nitrogen as well as lower serum albumin level were observed in the remaining three groups at 28 days after modeling. Compared with the model group, the levels of 24-hour urinary protein, blood cholesterol and urea nitrogen in the adipose stem cell transplantation group were decreased, while the level of serum albumin was increased. Compared with the adipose stem cell transplantation group, the levels of 24-hour urinary protein, blood cholesterol and urea nitrogen in the combined group were decreased, while the level of serum albumin was increased. (2) At 28 days after modeling, severest renal damage appeared in the model group, while the damage was reduced in the adipose stem cell transplantation group and considerably relieved in the combined group accompanied by improved inflammation and edema. (3) The number of CM-Dil positive cells in renal tissues was highest in the combined group followed by the adipose stem cell transplantation group, but no positive cells were detected in the normal control and model groups. Our experimental findings reveal that adipose-derived stem cell transplantation has a certain therapeutic effect on nephrotic syndrome, and adiponectin can enhance this therapeutic effect, by improving renal function and effectively inhibiting the pathological changes of renal tissues.
