Abstract
目的:探讨中性粒细胞(PMN)与内皮细胞(EC)黏附在急性胰腺炎(AP)早期发病中的机制及丹参对AP的治疗作用.方法:采用兔AP模型,24只日本大耳兔随机分为生理盐水组和丹参治疗组.分别于术前、术后即刻及2、4、8、12、16和24 h取血分离获得PMN,与体外培养的兔血管EC作用,测定PMN-EC黏附率及PMN表面黏附分子CD11a/CD18和CD11b/CD18值.结果:术后即刻两组黏附分子CD11a/CD18、CD11b/CD18及PMN-EC黏附率均升高,生理盐水组术后4 h达到高峰;丹参治疗组术后2、4、8、12、16和24 h的CD11a/CD18、CD11b/CD18显著低于生理盐水组.结论:丹参能降低黏附分子CD11a/CD18、CD11b/CD18表达,抑制PMN-EC黏附,改善微循环及减轻PMN-EC黏附所致的组织损伤,有助于AP的早期治疗.
