摘要

目的探讨高声压脉冲超声空化作用对兔肝细胞水通道蛋白4（AQP 4）及钠钾ATP酶（Na+-K+ATPase）表达的影响。方法将健康新西兰大白兔41只随机分为空白对照组（n=5）及不同辐照时间组:T1组（辐照时间1 min

n=12）、T5组（辐照时间5 min

n=12）及T10组（辐照时间10 min

n=12）;T1、T5及T10组采用高峰值负压（P=2.0 MPa）脉冲超声联合经静脉脂质微泡注射行肝脏超声辐照

随后获取肝脏组织标本;空白对照组仅行开腹手术获取肝脏组织标本。免疫组织化学法观察各组AQP 4及Na+-K+ATPase蛋白表达分布情况;蛋白免疫印迹法检测各组AQP 4及Na+-K+ATPase蛋白表达量。结果超声辐照后T1、T5及T10组AQP 4及Na+-K+ATPase强阳性表达细胞均较空白对照组数量增多、分布范围广泛;AQP 4蛋白表达量均较空白对照组显著增高

差异均有统计学意义（均P<0.05）

且T1、T10组与T5组AQP 4蛋白表达量比较差异均有统计学意义（均P<0.05）

T1组与T10组比较差异无统计学意义;T5组和T10组Na+-K+ATPase蛋白表达量明显高于空白对照组及T1组

差异均有统计学意义（均P<0.05）

T5组与T10组比较差异有统计学意义（P<0.05）

T1组与空白对照组比较差异无统计学意义。结论高声压脉冲超声空化作用在引起正常兔肝脏组织水肿的同时可引起AQP 4及Na+-K+ATPase蛋白表达量的增加

超声辐照时间的长短可影响蛋白表达量。

Abstract

Objective To investigate the effects of acoustic cavitation on the expression of proteins-aquaporin 4（AQP 4） and sodium potassium ATP enzyme（Na+-K+ATPase） in normal rabbit hepatocytes.Methods Forty-one healthy New Zealand white rabbits were randomly divided into the control group（n=5） and three different irradiation time groups:T1 group（irradiation time was 1 min

n=12）

T5 group（irradiation time was 5 min

n=12） and T10 group（irradiation time was 10 min

n=12）.Animals in T1 group

T5 group and T10 group were treated with high peak negative pressure（P=2.0 MPa） ultrasound irradiation combined with microbubble.Liver tissue specimens were obtained after ultrasound irradiation.Liver tissue specimens were taken by laparotomy in the control group.Distribution of AQP 4 and Na

-K

ATPase in each group was observed by immunohistochemical method

and expression of both protein was detected by Western blot.Results AQP 4 and Na

-K

ATPase positive cells of treatment groups were more than those of control group.AQP 4 protein expression of T1 group

T5 group and T10 group were significantly higher than that of control group（all P

0.05）.Comparison between groups showed that the expression of AQP 4 of T5 group was significantly higher than that of T1 group and T10 group（both P

0.05）

while the difference between T1 group and T10 group was not statistically significant.The expression of Na

-K

ATPase of T5 group and T10 group were significantly higher than that of control group and T1 group（all P

0.05）

while the difference between T1 group and control group was not statistically significant.Expression of Na

-K

ATPase in T5 group was significantly higher than that of T10 group（P

0.05）.Conclusion Microbubble enhanced cavitation could increase expression of AQP 4 and Na

-K

ATPase in normal rabbit liver while induce liver edema

and ultrasonic irradiation time is closely related to protein expression.
