目的 探讨高迁移率族蛋白B1（HMGB1）在食管鳞癌患者血清中的表达及其作为食管鳞癌肿瘤标志物的可行性.方法 回顾性分析201 1年1-12月间天津医科大学附属肿瘤医院食管肿瘤科收治的78例食管鳞癌患者的临床病理资料,以酶联免疫吸附测定法、电发光免疫测定法和微粒酶联免疫测定法分别检测78例食管鳞癌患者术前和术后1个月血清HMGB1、癌胚抗原（CEA）、细胞角蛋白19片段抗原（Cyfra21-1）及鳞状上皮细胞癌相关抗原（SCC）的水平.以60名健康成人血清HMGB1的95％单侧参考值范围作为阳性判定标准（大于96 μg/L）;以CEA大于5.0 μg/L、Cyfra21-1大于3.3 μg/L、SCC大于1.5μg/L作为其他血清标记物的阳性判定标准.结果 78例食管鳞癌患者术前血清HMGB1水平为（748.7±92.4） μg/L,其表达水平与肿瘤大小、浸润深度、淋巴结转移及肿瘤分期有关（P＜0.01,P＜0.05）.术后1个月,患者血清HMGB1表达水平为 （181.4±20.5） μg/L,较术前明显下降（P＜0.01）;但在T4、N1和Ⅲ期中仍相对较高（P＜0.01,P＜0.05）.血清HMGB1对食管鳞癌诊断的灵敏度为 84.6％（66/78）,明显高于CEA[10.3％ （8/78）]、Cyfra21-1[25.6％（20/78）]和SCC [42.3％ （33/78）];但4种血清肿瘤标记物特异度均较高,分别为93.3％（56/60）、88.3％（53/60）、90.0％（54/60）和 93.3％（56/60）.结论 与CEA、Cyfra21-1和SCC相比,血清HMGB1检测食管鳞癌灵敏度高,易于检测,特异度好,可作为肿瘤标志物用于食管鳞癌的辅助诊断、病期评价及预后判断.     

持续性非卧床腹膜透析患者微炎性反应状态及其与动脉硬化和心脏功能的关系

目的 研究持续性非卧床腹膜透析（CAPD）患者血清炎性反应标志物水平与动脉硬化和心脏功能的关系。 方法 以27例慢性肾脏病（CKD）5期非透析患者及27例健康人为对照，对我院腹膜透析中心随诊的67例CAPD患者进行微炎性反应状态的横断面调查与分析。收集相关的临床及实验室资料。ELISA法检测血清白细胞介素6（IL-6）、IL-10水平。免疫透射比浊法检测超敏C反应蛋白（hs-CRP）水平。颈动脉彩超和超声心动图分别检测颈动脉硬化和心脏功能。 结果 与健康对照组血清IL-6(ng/L)、IL-10(ng/L) 及hs-CRP(mg/L)比较（中位数为0.698、0.277及0），CAPD患者（2.400、1.988及1.090）和CKD5期患者（1.515、1.958及1.345）均显著升高；颈动脉硬化（44.8%、 33.3%比14.8%）和左心室肥厚（LVH，70.1%、81.5%比3.7%）的发生率显著增加；左心室重量指数（LMVI）和心脏功能综合指数（Tei，0.75±0.31、0.66±0.27比0.52±0.23）亦显著升高（P < 0.01）。但CAPD患者与CKD5期患者上述指标间差异无统计学意义。IL-6、SDS抑郁量表评分和脉压差是CAPD患者发生颈动脉硬化的独立危险因素。IL-6与Tei指数呈正相关；IL-10与LVMI呈负相关，与心脏射血分数（EF）呈正相关。IL-6和原发性高血压病是CAPD患者Tei指数升高的独立危险因素。结论 CKD5期非透析和CAPD患者存在微炎性反应状态，且与颈动脉硬化和心脏功能异常有关。IL-6是腹膜透析患者发生颈动脉硬化和Tei指数升高的独立危险因素。

持续性非卧床腹膜透析患者血钾浓度变化的临床意义

持续性非卧床腹膜透析（CAPD）具有操作简便、对中分子毒素清除效果好,对血流动力学影响小等优点,且随着腹膜透析技术的进步,腹膜炎等相关并发症的发生率明显下降,接受CAPD治疗的患者逐年增加。在这种情况下,电解质紊乱,尤其低血钾已成为影响CAPD疗效的重要因素之一。本文回顾性分析2007年10月至2009年4月我院CAPD患者的血钾浓度变化及其临床意义。     

Body composition and nutritional status in patients on continuous ambulatory peritoneal dialysis (CAPD)

Total body water (TBW), extracellular water (ECW), exchangeable potassium pool (EKP), and alkali-soluble nitrogen in skeletal muscle tissue (N) were determined in 9 CAPD patients on treatment from 5 to 14 months (mean 8.6 months). The parameters were reevaluated in 6 of these patients 5 to 13 months later (mean 8.6 months). The mean value of TBW was normal and directly correlated to body weight (BW), but TBW was abnormally distributed between extracellular and intracellular space. ECW volume was significantly lower than the predicted value (12.1 +/- 1.4 versus 16.8 +/- 1.9 l) and out of proportion to TBW (34.8 +/- 3.9% versus 47.8 +/- 1.5%). The calculated intracellular water, therefore, appeared clearly hyperexpanded. The mean value of EKP was slightly reduced, but in three patients there was a 25% reduction. N content was low in 5 out of 9 patients. When the parameters were re-evaluated BW and TBW were unchanged in two subjects. A third patient showed a simultaneous increase in both BW (12.7%) and TBW (19%). TBW variations (+19%, -23%, -24%) without changes in BW were seen in three patients. The mean value of EKP was unchanged, but there was a 25% reduction in one patient. N content improved in two and worsened in one of the three patients in whom it was determined. The data suggest that cell overhydration was the distinctive feature in our CAPD patients, and that the evolution of the nutritional status was variable, since the patients could remain stable, gain or loose body fat, and probably change their lean body mass.     

透出液蛋白丢失与连续性非卧床腹膜透析患者营养不良-炎性反应-动脉硬化综合征的相关性

Objective To investigate the impact of peritoneal albumin leakage on malnutrition-inflammation-atherosclerosis (MIA) syndrome in continuous ambulatory peritoneal dialysis (CAPD) patients. Methods A cross-sectional study of a cohort of 130 CAPD patients without edema or active infection was performed. In order to identify peritoneal transport characteristics in CAPD patients, a standard peritoneal equilibration test (PET) was carried out. For malnutrition and inflammation, serum albumin and high-sensitivity C-reactive protein (hs-CRP) levels were measured. Mean-carotid artery intima media thickness (IMT) was used to determine atherosclerosis. Residual glomerular filtration rate (rGFR) was defined as the average of 24-hour urinary urea and creatinine clearances. Results Pearson and Spearman correlation analysis showed that peritoneal albumin leakage amount was positively correlated with age, body mass index, night dwell time, blood glucose, 4 h D/P creatinine levels and hs-CRP levels (r=0.204, P<0.05 ;r=0.314, P<0.01; r=0.265, P<0.01; r=0.212, P<0.05; r=0.401, P<0.01; r=0.216, P<0.05); whereas it was negatively correlated with diastolic perssure, serum albumin levels, glucose level of dialyzate and peritoneal Kt/V (r=-0.209, P<0.05; r=-0.123, P<0.05; r=-0.271, P<0.01; r=-0.212, P<0.01). Overall, there was no correlation between peritoneal albumin leakage and IMT. Patients was significantly greater (P<0.01), and there was a positive correlation between peritoneal albumin leakage amount and IMT (r=0.650, P<0.01). Conclusions Peritoneal albumin leakage is significantly associated with peritoneal transport characteristics, malnutrition and inflammatory state in CAPD patients. High peritoneal albumin leakage amount is a risk factor for atherosclerosis in patients with rGFR less than 1 ml·min-1(1.73 m2)-1.

透出液蛋白丢失与连续性非卧床腹膜透析患者营养不良-炎性反应-动脉硬化综合征的相关性

目的 探讨透出液蛋白丢失对连续性非卧床腹膜透析（CAPD）患者营养不良-炎性反应-动脉硬化（MIA）综合征的影响。 方法 对130例无明显水肿和活动性感染的CAPD患者进行横断面的研究。用标准腹膜平衡试验（PET）评估CAPD患者腹膜转运功能。颈动脉彩色超声检测颈动脉内膜中层厚度（IMT）。检测患者血清白蛋白、夜间留腹透出液蛋白和超敏C反应蛋白（hs-CRP）的水平。残余肾功能（rGFR）为24 h尿尿素氮和尿肌酐清除的平均值。 结果 Pearson和Spearman相关分析显示,CAPD透出液蛋白的丢失与年龄、体质量指数（BMI）、夜间腹透液留腹的时间、血糖、4 h透出液肌酐与血肌酐比值（4 h D/Pcr）及hs-CRP水平呈正相关（分别为r = 0.204,P < 0.05;r = 0.314,P < 0.01;r = 0.265,P < 0.01;r = 0.212,P < 0.05;r = 0.401,P < 0.01和r = 0.216,P < 0.05）;与舒张压、血清白蛋白、透析液糖浓度及腹膜Kt/V呈负相关（分别为r = －0.209,P < 0.05;r = －0.123,P < 0.05;r = －0.271,P < 0.01;r = －0.212,P < 0.01）。总体上,透出液蛋白丢失量与IMT无相关,但患者rGFR小于1 ml·min^－1·（1.73 m²）^－1时,透出液蛋白丢失量与IMT呈正相关（r = 0.650,P < 0.01）。 结论 CAPD患者透出液蛋白的丢失与患者腹膜转运类型、营养不良和炎性反应状态密切相关。患者rGFR小于1 ml·min^－1·（1.73 m²）^－1时,透出液蛋白的丢失是颈动脉动脉硬化的危险因素。
