Objective To investigate the association between the level of advanced oxidation protein products (AOPP) in serum and the dialysate glucose exposure dose in patients undergoing non-diabetic maintenance peritoneal dialysis (PD). Methods In this cross-sectional study, the levels of serum AOPP were measured in 192 non-diabetic PD patients. Based on the exposure dose of dialysate glucose , PD patients were assigned into the high-dose exposure and low-dose exposure groups. Serum C-reactive protein levels were also measured and the rates of cardio-vascular disease (CVD) were recorded in both groups. Results The levels of serum AOPP were higher in the high-dose exposure group, as compared with the low-dose exposure group [(78.7 ± 15.6) mmol/L vs. (71.7 ± 14.8) mmol/L, P = 0.003]. The serum C-reactive protein levels [4.6 (3.0-11.4) mg/L vs. 3.0 (2.2-5.3) mg/L, P < 0.001] and the rates of CVD (53.6% vs. 35.8%, P = 0.014) were also higher in the high-dose exposure group. After multivariate adjustment ,the level of serum AOPP was independently associated with dialysate glucose exposure dose (β = 0.157, P = 0.031) and duration of PD (β = 0.164, P =0.043). Conclusion The serum AOPP levels are associated with the dialysate glucose exposure doses in non-diabetic PD patients. Minimizing the glucose load might reduce the risk of developing CVD.%目的：了解非糖尿病腹膜透析患者血清晚期氧化蛋白产物（AOPP）在不同透析液葡萄糖暴露量下的水平，探明血AOPP水平是否与腹膜透析液葡萄糖暴露程度相关。方法：对192例非糖尿病腹膜透析患者进行横断面研究。按透析液葡萄糖暴露量将患者分为高糖暴露组和低糖暴露组。检测所有患者空腹血清AOPP和C反应蛋白水平，记录两组患者的心血管疾病患病率。结果：高糖暴露组的血清AOPP水平显著高于低糖暴露组[（78．7±15．6）mmol／L vs （71．7±14．8）mmol／L， P ＝0．003]。高糖暴露组患者血C反应蛋白[4．6（3．0～11．4）mg／L vs 3．0（2．2～5．3）mg／L， P ＜0．001]和心血管疾病患病率（53．6％ vs 35．8％， P ＝0．014）均显著高于低糖暴露组。经多因素校正后，血清AOPP水平与透析液葡萄糖暴露量（β＝0．157， P ＝0．031）和透析时长（β＝0．164， P ＝0．043）独立相关。结论：非糖尿病腹膜透析患者血清AOPP水平与透析液葡萄糖暴露程度相关，减少葡萄糖暴露度可能降低非糖尿病腹膜透析患者的心血管疾病发生风险。
