Retinol-binding protein and prealbumin in cord blood of term and preterm infants

Retinol-binding protein (RBP) and prealbumin (PA) are potentially useful indicators of inadequate protein and/or energy intake. Concentrations of RBP and PA were determined in cord blood of 117 infants and were found to be lower before 37 weeks gestation than at term. Adult subjects had substantially higher concentrations of RBP and PA than found in cord blood.

Discrepancy between the Measurement of Thyroxine-Binding Prealbumin Plasma Level and Binding Capacity in Protein-Calorie Malnutrition

Abstract. The measurement of thyroxine-bindung prealbumin (TBPA) in protein-calorie malnutrition by two different techniques leads to the recognition of an unexpected discrepancy. Whereas TBPA plasma levels as measured by immunodiffusion are markedly decreased to 29. 3 % of the normal, those recorded by maximal binding capacity (TBPA_cap) are characterized by a wide dispersion. In the control group, the ratio between TBPA and TBPA plasma level is 9. 1. In the malnourished group on admission, the same ratio is     

肿瘤相关性贫血铁代谢及前白蛋白水平变化的临床意义

目的 分析实体肿瘤患者贫血发生情况、贫血类型、铁代谢状况、前白蛋白水平的变化情况及其之间的相关性.方法 对2007年7月至2010年4月期间我院收治的370例恶性实体肿瘤患者的临床资料进行回顾性分析.结果 370例肿瘤患者中有206例存在贫血,发生率55.67%(206/370),其中轻度贫血129例,中、重度贫血77例,后者血清铁明显降低[(8.37±6.09)μmol/L];血清铁蛋白增高[(474.57±327.58)μg/L];血清铁降低与贫血程度有相关性(P＜0.05),而不同程度贫血之间血清铁蛋白差异无统计学意义(P＞0.05);所有贫血患者中,前白蛋白下降187例(90.77%),贫血下降的程度与前白蛋白下降未显示有相关性(P＞0.05).结论 恶性实体肿瘤患者贫血发生率较高,而且以正细胞正色素性贫血为主,与铁代谢障碍有关,与前白蛋白水平无相关性.

Abstract：

Objective To explore the occurrence of anemia, anaemia type, iron metabolism situation,variation of serum Prealbumin (PA), and the relationship among them in cancer patients. Methods Three hundred and seventy cancer patients, admitted from July 2007 to April 2010 to our hospital, were enrolled into the study. The clinical data of all subjects were analyzed retrospectively. Results The incidence of anemia in 370 patients was 55.67% (206/370). Among all 206 anemia cases,129 cases had mild anaemia and 77 cases had middle to severe anaemia. In the last group ( n = 77 ), we found significant decrease in serum iron level ( [ 8. 37 ± 6. 09 ] μmol/L) and increase in serum ferritin level ( [ 474. 57 ± 327. 58 ] μg/L); and the correlation between serum iron and the anemia degree( Ps ＜ 0. 05 ). However, we found no significant differences of serum ferritin level between the groups with different degree of anemia(P ＞0. 05). Among all 206 anemia cases ,187(90. 77% ) patients had a low level of serum PA, but no relationship between the degree of anemia and the drop of serum PA ( P ＞ 0. 05 ). Conclusion The anemia was very popular in cancer patients, which had correlation with iron metabolism situation but not PA.     

直肠癌术后吻合口瘘患者CRP、A1b、PA水平的变化及意义

目的分析直肠癌术后吻合口瘘患者血液中C反应蛋白（C—reactiveprotein,CRP）值、白蛋白（albumin,Alb）值、前白蛋白（prealbumin,PA）值的变化及临床意义。方法根据吻合口痿发生情况,将151例直肠癌保肛手术患者分成吻合口瘘组（20例）合对照组（131例）,比较并分析术后第1、3、5、7天两组患者血液中CRP值、Alb值、PA值。结果术后,吻合口瘘组患者CRP值呈上升趋势,Alb值、PA值呈下降趋势,对照组CRP值呈下降趋势,Alb值、PA值呈上升趋势。术后第1天,两组CRP值差异无统计学意义（P〉0．05）;术后第3、5、7天,两组CRP值差异有统计学意义（P〈0．05）。术后第1、3天,两组Alb值差异无统计学意义（P〉0．05）;术后第5、7天,两组Alb值差异有统计学意义（P〈0．05）;术后第1、3、5、7天,两组PA值差异均有统计学意义（P〈0．05）。结论直肠癌术后动态监测患者血液中CRP值、Alb值、PA值有助于早期发现吻合口瘘。     

Expression differences of serum prealbumin in benign and malignant colorectal tumors

Objective： The aim of the study was to investigate the expression differences of serum prealbumin in patients with benign and malignant colorectal tumors and its clinical significance. Methods： The concentrations of total protein, albumin, prealbumin, hemoglobin of 113 colorectal cancer patients （cancer group） and 87 colorectal adenomas （adenoma group） were tested in Yixing Hospital Affiliated to Jiangsu University （China） during August 2013 to December 2013. Then the differences between the two groups were compared. Results： In colorectal cancer patients, the concentrations of serum prealbumin in 39/113 cases, total protein in 16/113 cases, albumin in 38/113, hemoglobin in 32/113 were lower than normal ranges. While, in colorectal adenoma patients, the concentrations of serum prealbumin in 4/87 cases, total protein in 2/87, albumin in 1/87, hemoglobin in 2/87 were below the detection limit. Comparative analysis showed that, average expression levels of serum prealbumin, albumin, total protein, hemoglobin in colorectal cancer patients were lower than those of colorectal adenoma patients, the difference was statistically significant （P 〈 0.05）, and colorectal cancer patients were more likely to have lower levels of above indicators （P 〈 0.05）. Conclusion： Compared to colorectal adenoma patients, patients with colorectal cancer have lower average expression levels, and were easier to have lower expression levels of serum albumin, albumin, total protein and hemoglobin, which suggest that colorectal cancer patients are more likely to have metabolic change, and clinic notable.

血清降钙素原与前白蛋白检测在儿童发热性疾病诊断中的意义

目的探讨血清降钙素原(PCT)与前白蛋白(PA)检测在儿童发热性疾病诊断中的意义。方法根据病原学诊断结果将100例发热性疾病患儿分为细菌感染组54例和病毒感染组46例,另选取同期体检结果正常儿童50例作为对照组。对3组儿童的血清PCT水平和PA水平进行检测和比较。结果细菌感染组患儿的血清PCT水平显著高于病毒感染组和对照组(P0.05),血清PA水平显著低于病毒感染组和对照组(P0.05);联合检测诊断细菌感染性发热的敏感性显著高于单独应用血清PCT检测或血清PA检测(P0.05),且血清PCT检测的敏感性显著高于血清PA检测(P0.05)。结论血清PCT水平的上升和血清PA水平的下降可提示有细菌感染性发热的发生,二者联合检测可提高诊断细菌感染性发热的敏感性。
