目的探讨经皮导管引流(percutaneous catheter drainage,PCD)对大鼠重症急性胰腺炎(severe acute pancre-atitis,SAP)胰腺损伤的影响及意义。方法 60只Wistar大鼠按随机数字表法分为假手术组(仅行开腹手术)、SAP组(逆行胰胆管注射牛磺胆酸钠诱导SAP大鼠模型)和PCD治疗组(在SAP组基础上行PCD治疗),每组20只,每组分6、24 h2个时相点,每时相点10只。分别于术后6、24 h取血清及腹水测定TNF-α、IL-1β及淀粉酶、蛋白酶水平,留取胰腺组织制作石蜡切片行光镜下病理检查、免疫组化检测Bcl-2、Bax在胰腺组织的表达以及采用TUNEL染色观察胰腺组织细胞的凋亡指数。结果注射牛磺胆酸钠后大鼠血清淀粉酶、TNF-α、IL-1β在造模后有显著升高(P<0.05),相同时相点的大鼠经PCD治疗后血清及腹水中炎症因子及腹水中蛋白酶含量即有明显下降(P<0.05),光镜病理检查提示PCD治疗组大鼠胰腺病理损伤较未治疗的SAP大鼠明显改善,TUNEL染色可见术后24 h PCD治疗组大鼠胰腺组织细胞凋亡指数较未治疗的SAP组高[(14.6±2.1...
【英文摘要】
Objective To determine the effect of percutaneous catheter drainage(PCD) on pancreatic injury of severe acute pancreatitis(SAP) rats and its significance.Methods Sixty Wistar rats were equally randomized into 3 groups,sham-operation group,SAP model group and PCD group.Acute hemorrhagic pancreatitis was induced in rats by injecting 5% sodium taurocholate(2 mL/h,0.1 mL/100 g) into the common bilio-pancreatic duct.Rats in each group were then divided into 2 subgroups,which were killed in 6 and 24 h after opera...
