摘  要:目的探讨膀胱尿路上皮癌患者机体氧化应激变化及其与疾病严重程度的关系。方法膀胱癌组来自2009年6月至2011年6月我院收治的膀胱尿路上皮癌患者共159例,包括非肌层浸润性膀胱癌(Ta、T1)患者117例、肌层浸润性膀胱癌(T2以上)42例。选择同期健康体检人群120例作为正常对照组。分别检测各组血清维生素(Vit)C、VitE、超氧化物歧化酶(SOD)、谷胱苷肽过氧化物酶(GPx)、丙二醛(MDA)、总抗氧化活性(AOA)等。结果膀胱癌组血清VitC、VitE、SOD、GPx、AOA均明显低于正常对照组[(0.023±0.006)ms/L比(0.057±0.009)mg/L,(0.082±0.021)mg/L比(0.149±0.012)ms/L,(31±12)kU/L比(201±31)kU/L,(2136±436)U/L比(7674±922)U/L,(0.90±0.04)nmol/L比(1.67±0.29)nmo]/L,均P〈0.01];但MDA含量明显高于正常对照组[(12.6±4.2)ixmol/L比(3.1±0.9)μmol/L,P〈0.01]。非肌层浸润性膀胱癌患者血清VitC、VitE、SOD、GPx均明显高于肌层浸润性膀胱癌[(0.027±0.014)mg/L比(0.012±0.005)ms/L,(0.095±0.019)ms/L比(0.046±0.007)ms/L,(37.1±10.9)kU/L比(14.9±2.7)kU/L,(2422±457)U/L比(1339±264)U/L,均P〈0.01];MDA含量低于肌层浸润性膀胱癌[(7.8±1.1)μmol/L比(25.8±3.6)μmol/L,P〈0.01];2组AOA差异无统计学意义(P〉0.05)。结论膀胱尿路上皮癌的发生发展与机体氧化应激有关,补充外源性抗氧化剂可能有助于膀胱尿路上皮癌的治疗和预防。Objective To assess the changes of oxidative stress in patients with bladder urothelial carcinoma. Methods All 159 patients (Ta ± T1, 117; ≥ T2, 42 ) were bladder urothelial carcinoma and 120 healthy controls were chosen. Vitamins C and E, superoxide dismutase (SOD), glutathione peroxidase (GPx), malondiatdehyde (MDA) and total antioxidant activity (AOA) were estimated. Results The serum levels of vitamins C and E, SOD, GPx and AOA were significantly lower [ (0. 023 ± 0.006)mg/L vs (0.057 ± 0.009 )mg/L, (0.082 ±0.021 ) mg/L vs (0. 149 ± 0. 012) mg/L, ( 31 _± 12) kU/L vs (201 ± 31 ) kU/L, (2136 ± 436) U/L vs (7674 ± 922 ) U/L, ( 0.90 ± 0. 04 ) nmol/L vs ( 1.67 ± 0.29 ) nmol/L, all P 〈 0.01 ] while serum MDA levels were significantly higher in patients than those in controls E ( 12.6 ± 4.2 ) μmol/L vs (3.1 ± 0.9 ) μmol/L, P 〈 0. 01 ]. There were significant differences between the patients with non-muscle invasive bladder tumors and muscle invasive tumors for vitamins C and E, SOD and GPx I ( 0. 027 ± 0. 014 ) mg/L vs ( 0. 012 ± 0. 005 ) rng/L, ( 0. 095 ± 0. 019) mg/L vs (0. 046 ± 0. 007) rag/L, (37.12 ± 10.9) kU/L vs ( 14.9 ± 2.7 ) kU/L, (2422 ± 457) U/L vs ( 1339 ± 264) U/L, all P 〈 0.01 ], except AOA ( P 〉 0. 05 ). Conclusions The oxidative stress of bladder urothelial carcinoma in correlation with the severity of the disease, and it may be important factors in tumor development and growth. These findings suggest possible use of antioxidant supplementation as prophylaetic agent for prevention and treatment of bladder cancer.
