16年腹膜透析的基础和临床研究回顾

总结16年以来中南大学湘雅二医院肾内科腹膜透析的基础与临床研究的经验与成果。在国内率先成功构建了腹膜透析及腹膜纤维化动物模型，分离、鉴定了腹膜间皮细胞；利用细胞、分子生物学方法，系统研究了腹膜透析液的生物相容性、腹膜间皮细胞透析损伤的分子机制与防治措施，观察了促纤维化细胞因子转化生长因子-β1(TGF-β1),结缔组织生长因子（CTGF）及过氧化物酶体增生物激活受体-γ（PPAR-γ)等在腹膜纤维化发病机制中的重要作用，并初步阐明了它们的基因表达调控机制。首次在腹膜透析研究领域中利用纳米载体介导TGF-β1-shRNA与pCTGF-shRNA质粒在腹膜细胞与组织中的表达。在临床研究方面，研究了腹膜透析置管定位新方法、腹膜透析溶质转运特点及其机制、腹膜透析治疗模式及其他并发症的防治。

Basic experimental and clinical research on peritoneal dialysis in the past 16 years

To summarized the experiences from our basic experimental and clinical research on peritoneal dialysis. In the past 16 years, peritoneal fibrosis rat models and rabbit models of peritonitis were first established successfully in our laboratory in China. Peritoneal mesothelial cells were also separated and identificated. Besides, we assessed the biocompatibility of peritoneal dialysis fluid and analyzed the molecular mechanism of peritoneal mesothelial cell injury. We demonstrated the key role of transforming growth factor-β1 (TGF-β1), connective tissue growth factor (CTGF) and peroxisome proliferative activated receptor-γ (PPAR-γ) in the pathogenesis of peritoneal fibrosis, as well as their regulation of molecular mechanism. Furthermore, we transfected the plasmids encoding TGF-β1-shRNA or pCTGF-shRNA into peritoneal cells and tissues by nanocarrier technologies. In clinical research, the positioning of peritoneal dialysis catheters, peritoneal dialysis treatment modalities and the prevention and treatment of its complications were studied. The characteristics and mechanism of solute transport in peritoneal dialysis was also explored.
