ORP150在重症急性胰腺炎大鼠胰腺中表达变化的研究

目的探讨氧调节蛋白150(ORP150)在重症急性胰腺炎(SAP)大鼠胰腺损伤中的表达变化。方法将40只雄性Wistar大鼠随机分为:假手术组(SO组,10只)、SAP组(30只,其中SAP 3、6及12h3个时相各10只)。SO组开腹后仅翻动胰腺则关腹,SAP组则经胆胰管逆行注射5%牛磺胆酸钠制备SAP模型;测定SO组术后12h和SAP组造模后3、6及12h的腹水量、血清淀粉酶(AMY)及谷氨酸氨基转移酶(ALT)水平;于光镜下进行胰腺组织病理学评分;用RT-PCR法检测胰腺组织中ORP150mRNA的表达。结果 SAP组各时相腹水量,AMY及ALT水平和胰腺病理评分均明显高于SO组(P<0.05)。SAP组腹水量在造模后3h和6h之间差异无统计学意义(P>0.05),而12h较前2个时相均明显增高(P<0.05)。SAP组的AMY及ALT水平和胰腺组织病理学评分在造模后各时相两两间比较差异均有统计学意义(P<0.05)。ORP150mRNA在SO组呈低表达,在SAP组造模后各时相的表达强度均较SO组增强,其中造模后3h表达强度最高,6h和12h依次降低。结论 ORP150mRNA在SAP胰腺组织中呈高表达,提示ORP150可能在SAP胰腺损伤的发生、发展过程中起着一定的作用。

Study on Expression of ORP150 in Pancreas of Rats with Severe Acute Pancreatitis

Objective To explore the change of expres sion of oxygen-reg u lated protein 150(ORP150) in pancreatic injury of rats with severe acute pancr eatitis.Methods Forty male Wistar rats were randomly allocat ed into two groups: sham operation group(SO group,n=10) and severe acute pancreatitis model group(SAP group,3 h,6 h,and 12 h after modeling,each time n=10). SO group rats were only turned over the pancreas,and the SAP group rats were induc ed by retrogradely infusing 5% sodium taurocholate into the bili opan...
