Abstract： 目的:研究连接黏附分子C(JAM-C)在小鼠急性坏死性胰腺炎(ANP)模型胰腺、肾脏和肺脏组织中的表达.方法:采用雨蛙素和脂多糖联合腹腔注射的方法建立小鼠ANP模型.模型组(ANP组)小鼠腹腔内注射雨蛙素(50 μg/kg),连续6次,每次间隔1 h,在末次注射雨蛙素后,即向小鼠腹腔内注射脂多糖(LPS)(10 mg/kg);对照组小鼠腹腔内注射等体积生理盐水.在末次注射3 h后,用眼球取血法收集血液,检测血清淀粉酶,并取胰腺、肾脏、肺脏组织,通过Western blot印迹杂交法检测JAM-C在这些组织上的表达.结果:JAM-C在ANP组的胰腺、肺脏和肾脏上均有着高表达,大于生理盐水对照组3倍以上(0.608±0.133 vs 0.176±0.024,0.718± 0.148 vs 0.160±0.027,0.654±0.085 vs 0.166±0.039,均P<0.05).结论:在小鼠ANP模型中,JAM-C在胰腺、肾脏和肺脏上的表达均明显增高,提示JAM-C在ANP发病过程中起到重要的作用.
