【摘要】 目的 探讨甘油三酯（triglyceride，TG）和总胆固醇（total cholesterol，TC）试剂对血清总胆汁酸（total bile acid，TBA）检测结果的影响及解决办法。 方法 2008年1月-2009年10月采用魅力2000全自动生化分析仪，首先单独检测20份血清标本的TBA 含量。然后分别检测TC和TG后进行TBA含量检测。最后设定特殊检测程序和清洗程序后再按TC→TBA，TG→TBA顺序进行TBA含量检测。 结果 单独检测20份血清标本的TBA结果均值为7.2 μmol/L;按TC→TBA，TG→TBA顺序检测结果均值分别为13.5 μmol/L和14.3 μmol/L，单独和组合测量方法测定TBA结果有统计学意义（Plt;0.05）。设定特殊检测程序和清洗程序后按TC→TBA，TG→TBA顺序检测结果均值分别为7.4 μmol/L和7.5 μmol/L，与单独测量TBA结果相比，无统计学意义。 结论 TG和TC试剂对TBA检测产生干扰的原因是试剂成分中含有浓度较高的TBA，在魅力2000全自动生化分析仪上，设定特殊检测程序和清洗程序，能有效消除TG、TC试剂对TBA检测的影响。【Abstract】 Objective To explore the influence and procedure improvement strategies of triglyceride (TG) and cholesterol reagent on the result of serum total bile acid (TBA) test. Methods The study was carried out between January 2008 to October 2009. The charming 2000 automatic biochemical analyzer was used. First, TBA content of 20 serum samples was independently tested. Then TBA was detected after the detection of TG and total cholesterol (TC) concentration. Finally, TBA test was conducted with special testing procedures and cleaning procedures of TC→TBA and TG→TBA method. Results The average concentrate of TBA of 20 serum samples was 7.2 μmol/L, while the average concentrates of TBA tested by TC→TBA and TG→TBA methods were 13.5 μmol/L and 14.3 μmol/L, respectively. With special testing procedures and cleaning procedures of TC→TBA and TG→TBA tests, the average concentrates of TBA were 7.4 μmol/L and 7.5 μmol/L, respectively. Conclusion High concentration of TBA in triglyceride and cholesterol reagents contributes substantially to the interference in serum total bile acids detection. With the charming 2000 automatic biochemical analyzer, special testing procedures and cleaning procedures are able to effectively eliminate the interference of triglycerides and cholesterol reagents from TBA detection.
目的：测定妊娠期肝内胆汁淤积症(ICP)患者血清及尿液的胆汁酸水平，探讨ICP时母体胆汁酸转运的变化及意义。方法：ICP患者(ICP组)及正常妊娠(对照组)各20例。血清及尿液总胆汁酸测定采用速率法。结果：(1)ICP组与对照组相比，血清及尿液中总胆汁酸水平均明显升高，差异有显著性(Plt;0.05)；(2)对照组尿液总胆汁酸水平明显高于血清，差异有显著性(Plt;0.05)，而ICP组血清和尿液总胆汁酸水平无显著性差异(Pgt;0.05)；(3)两组中血清与尿液总胆汁酸水平均无相关性(Pgt;0.05)。结论：ICP患者母血中总胆汁酸水平明显增加，而总胆汁酸经尿液的排泄未成比例增加，这可加重胆汁淤积，引起围产儿不良结局。
摘要:目的: 探讨血清前白蛋白(prealbumin,PAB)、胆碱脂酶(cholinesterase,ChE)、总胆汁酸(total bile acid,TBA)在肝硬化中的检测价值。 方法 :测定105例肝硬化患者和30例健康人的前白蛋白、胆碱脂酶、总胆汁酸活性及肝功能生化指标,并按ChildPugh分级进行比较。 结果 :肝硬化组前白蛋白含量、胆碱脂酶活性均较对照组显著降低;按ChildPugh分级比较,肝硬化组前白蛋白含量在Child A级与对照组、B级与A级之间、在C级与B级之间差异有显著性(Plt;001);胆碱脂酶活性在Child A级与对照组、B级与A级、C级与B级之间差异有显著性(Plt;001)。总胆汁酸在Child B级与A级,C级与B级间有显著差异性,在A级与对照组间差异无显著性。 结论 :血清前白蛋白、胆碱脂酶在肝硬化早期评估中有很重要的价值,而总胆汁酸在肝硬化预后的判定中有重要价值。 Abstract: Objective: To evaluate the role of prealbumin (PAB), cholinesterase (ChE), and total bile acid (TBA) in evaluating liver reserve function in patients with liver cirrhosis. Methods : One hundred and five serum samples from patients with liver cirrhosis were detected in PAB, ChE, TBA and other biochemical markers. All patients were classified in accordance with ChildPugh scale. Results : For PAB, the differences among ChildPugh A, B, C and healthy group were statistically significant (t=1254, 1887, 2316) (Plt;001). For ChE, the differences among ChildPugh A, B, C and healthy group were statistically significant (t=1288, 0856, 1002) (Plt;001). For TBA, the differences among ChildPugh C group, B group and A group were statistically significant (t=0526, 1081)(Plt;001), the difference among ChildPugh A group and healthy group was not statistically significant (t=5615) (Pgt;005). Conclusion : PAB and ChE reflect liver reserve function earlier in patients with liver cirrhosis. The role of TBA is important in reflecting prognosis in patients with liver cirrhosis.
ObjectiveTo explore the relationship between the levels of transferrin (TRF), prealbumin (PAB) and total bile acids (TBA) in serum and the loss of the hepatic reserve function in primary liver cancer (PHC) patients and the importance of the former factors for diagnosis of PHC. MethodsA total of 154 patients with PHC collected between March 2010 and February 2013 were included in our study. Based on the information of hepatic reserve function and the Child-Pugh classification standard, the patients were divided into Child-Pugh-A, B, and C groups with 67, 55 and 42 patients respectively. Another 58 healthy subjects were selected as the control group. Serum TRF, PAB and TBA levels were measured by automated chemiluminescence immunoassay, immune turbidimetric assay and enzymatic cycling respectively, and they were compared among the groups. ResultsTRF level of patients in the control group and Child-Pugh-A, B, and C groups was respectively (2.574±0.214), (1.618±0.135), (0.988±0.121), and (0.314±0.107) g/L, with significant differences among the groups (P<0.05). PAB level of patients in four groups was respectively (269.32±37.29), (165.22±21.01), (123.24±31.15), and (83.66±19.74) mg/L, with significant differences among the groups (P<0.05). TBA level in the above four groups was respectively (9.16±2.48), (65.13±4.25), (133.62±8.44), and (250.73±21.59) μmol/L, and there was also significant differences among the groups. A positive correlation between serum TRF and PAB was found (r=0.927, P<0.001), and negative correlations between serum TBA level and serum TRF and between TBA and PAB were found (r=-0.454, P<0.001; r=-0.432, P<0.001, respectively). ConclusionSerum TRF, PAB and TBA levels are closely related to the hepatic reserve function in PHC patients, and they can be used as an important indicator for PHC diagnosis.
ObjectiveTo observe the effects of oral Xiaoyan Lidan tablets(XYLDT) on the bile composition(total bile acids, cholesterol, phospholipids) in patients with intrahepatic duct stones after common bile duct exploration(CBDE) with T tube drainage, to explore its possible preventive effects on stone recurrence. MethodsForty consecutive patients with intrahepatic bile duct stones who underwent CBDE with T tube drainage were randomly divided into experi mental group and control group. XYLDT were administrated at day 4 after surgery in experimental group(n=20), while none of medication were given in control group(n=20). 2 mL of bile was collected through T tube in both groups at day 1, 2, 3, 7, 14, and 21 postoperatively. Total bile acids(TBA), cholesterol(CHO), and phospholipids(PLIP) in bile were measured, and TBA/CHO ratio and PLIP/CHO ratio were calculated respectively. The results were statistical analyzed. ResultsThe demographic data in both groups including age, gender, height, weight, preoperative concomitant diseases, operative time, postoperative complications, hospital stays, serum total bilirubin, direct bilirubin, alanine aminotransferase(ALT), aspartate aminotransferase(AST), and amylase were not significantly different(P > 0.05). The measurements of TBA, CHO, PLIP, and the ratio of TBA/CHO and PLIP/CHO in bile were not significant on day 1, 2, and 3 after surgery in both groups(P > 0.05). In experimental group, the TBA, CHO, and PLIP on day 7, 14, and 21 after surgery were significantly increased compared with the control group(P < 0.05). The ratio of TBA/CHO on day 7, 14, and 21 was 2.17±0.29, 2.29±0.44, and 2.59±0.58, the ratio of PLIP/CHO was 2.03±0.68, 2.84±0.64, and 2.86±0.77, respectively, which were also significantly increased compared with the control group(P < 0.05). ConclusionsOral XYLDT can increase the secretion of TBA, CHO, and PLIP, elevate the TBA/CHO and PLIP/CHO ratio, and change the bile composition which may increase the dissolution of cholesterol in the bile. Presumably, oral XYLDT may have preventive effects in the recurrence of intrahepatic bile duct stones.
