摘要: 目的

探讨6%羟乙基淀粉130/0.4(6%Hydroxyethyl Starch130/0.4,HES)用于肝硬化患者后对蛋白的影响及作用机制。

方法

选择肝硬化腹水患者48例,随机分为两组,分别输入乳酸钠林格(A组)和HES(B组)。患者每天输入1次,共7日,输入量为血容量公式计算血容量的5%。输液前(T0)输液第7天结束后的24小时(T1)测定总蛋白(Total protein,TB)、白蛋白(human serum albumin,HSA)、尿素氮(urea nitrogen,BUN)、肌酐(creatinine,Cr)。HES输入人体后与HSA结合,荧光光谱法分析HES和HSA的结合关系,进一步研究HES对患者HSA的影响机制。

结果

两组相比,B组HSA(29.3 ± 3.3)g/L、TP(57.4 ± 4.3)g/L在T1时高于A组HSA(26.7 ± 3.9)g/L、TP(53.9 ± 4.5)g/L。HES加入到HSA后,HSA的二级结构发生变化。随着HES浓度增加,HSA的荧光强度降低, HES诱发HSA荧光猝灭,HES与HSA的Trp-214(Trp∶色氨酸)形成1∶1的结合物。

结论

HES减少肝硬化患者低蛋白血症的发生,与HES和HSA的Trp-214结合形成1∶1复合物,体积增大,利于HES的机械堵漏。

Abstract: Objective

To investigate the influence mechanism of 6% hydroxyethyl starch 130/0.4 on protein in patients with liver cirrhosis patients.

Methods

Fourty-eighty patients with liver cirrhosis were selected and divided into two groups randomly: sodium lactate ringer group(group A) and HES group(group B). The patients of group A were infused with 5% blood volume of sodium lactate ringer once a day for 7 days, and group B were infused with 5% blood volume of HES once a day for 7 days. TB, human serum albumin (HSA), BUN and CREA were measured at before infusion (T0), 24 hours (T1) after the end of Day 7. When HES was infused into human body, and it was bound to HSA, and fluorescence spectroscopy analyzed the binding relationship between HES and HSA, and the effects of HES on proteins in patients were further studied.

Results

Compared with group A, HSA (29.3 ± 3.3)g/L and TP (57.4 ± 4.3)g/L in Group B were higher than those in group A(26.7 ± 3.9)g/L and TP (53.9 ± 4.5)g/L at T1. The secondary structure of HSA was changed after HES was added. And as the concentration of HES increased, the fluorescence intensity of HSA decreased, HES induced HSA fluorescence quenching, and HES form a 1∶1 structural binding relationship with tryptophan-214 of HSA.

Conclusion

6% HES reduces the occurrence of low protein in patients with liver cirrhosis, and it binds with HES to form a 1∶1 complex with Trp-214 amino acids, which increases the volume of HES in favor of mechanical plugging.
