摘 要:目的 研究腹腔镜手术时CO2气腹对SD大鼠重症急性胰腺炎病变局部、血淀粉酶、白细胞介素-6(IL-6)、E-选择素和P-选择素的影响. 方法 雄性SD大鼠50只,随机分为3组:CO2气腹组(n=20),5%牛磺胆酸钠胆胰管逆行注射方法制备SAP动物模型后,以气腹机向大鼠腹腔内注入CO2(压力12 mm Hg,维持30 min);SAP组(n=20):建立SAP模型后关腹,不充入CO2;单纯手术组(n=10):仅开腹翻动胰腺后关腹.各组均于术后2.5 h处死动物,取静脉血测定血淀粉酶、白细胞介素-6、E-选择素和P-选择素的水平,并进行胰腺组织病理学检查. 结果 与单纯手术组相比,CO2气腹组和SAP组病理学评分、血清淀粉酶、白细胞介素-6、E-选择素和P-选择索均明显升高,差异有统计学意义(P=0.000).与SAP组相比,CO2气腹组血白细胞介素-6明显降低,差异有统计学意义P=0.000;病理学评分(P=0.294)、血清淀粉酶(P=0.073)、E-选择素(P=0.126)和P-选择素(P=0.213)的差异无统计学意义. 结论 对于SAP大鼠,CO2气腹对白细胞介素-6有一定的抑制作用;对胰腺病理变化及E-选择素和P-选择素无明显影响.Objective To examine the effect of carbon dioxide pneumoperitoneum on local pancreas pathological changes, serum levels of amylase, IL-6, E-selectin and P-selectin in rats with severe acute pancreatitis (SAP). Methods Fifty healthy male SD rats were randomly divided into 3 groups: CO2 experiment group ( n =20): SAP was induced by injecting 5% sodium taurocholate through retrogradely common biliopancreatic ducts via duodenal papilla,and then CO2 pneumoperitoneum was established at a pressure of 12 mmHg for 30 min; SAP group ( n = 20): The rats were treated as same as CO2 experiment group, excepting CO2 pneumoperitoneum; Control group (n = 10): Abdomen was incised and nothing was done to duodenum and pancreas except for moving them softly. The blood samples were gathered for examining serum levels of amylase, IL-6, E-selectin and P-selectin, and histopathologic examination of pancreas was done.Results Compared with control group, the pancreatic pathologic histology score, serum levels of amylase,IL-6, E-selectin and P-selectin were significantly higher in the CO2 experiment group and SAP group (P =0.000). The levels of IL-6 were significantly lower in CO2 experiment group compared to SAP group (P =0. 000). There was no significant difference between CO2 experiment group and SAP group in pancreatic pathologic histology score( P =- 0.294), the levels of serum amylase ( P = 0.073 ), E-selectin and P-selectin. Conclusions CO2 pneumoperitoneum has no adverse effect on the changes of pathological histopathology and the levels of IL-6, E-selectin and P-selectin in SD rats with SAP.
