ABSTRACT Objective To discuss the importance of the study of conformation and variation of extrahepatic bile duct before gallbladder operationMethods The images of 100 cases having normal structure of gallbladder and extrahepatic bile duct were studied;the conformations and confluence sites were analyzedResults Among the 100 cases,97 cases had clear images of extrahepatic bile duct (97%),3 cases with large amount of air bulbs in bile duct because of the laxation of the lower common bile duct still had clear images of the general conformation of extrahepatic bile duct,87 cases had clear images of gallbladder and cystic duct (87%),13 cases (13%) had partial images of gallbladder or cystic ductConclusions ERCP can clearly show out the conformation and variation of extrahepatic bile duct and cystic duct and it is of important value before gallbladder operation

目的 通过对100例胆囊及肝外胆管正常结构尚存在的患者ERCP图像资料进行归纳和分析，探讨胆囊手术术前了解肝外胆道系统形态及变异的重要性。方法选出100例胆囊及肝外胆管正常结构尚存在的患者图像，对其形态、汇合位置进行分析。结果 100例患者图像中肝外胆管显示清晰者97例(97%)，3例因胆总管下端开口松弛导致大量气泡进入胆道，但肝外胆管大体形态显示尚清晰，胆囊及胆囊管显示清晰者87例(87%)，13例(13%)仅部分显示胆囊或胆囊管。结论 ERCP可以清晰显示肝外胆管及胆囊管的形态及变异情况，对于胆囊手术术前了解肝外胆道系统形态及变异有重要价值。 ERCP；胆囊管；肝外胆管

In presence of non- cancer suspicious patients, serum MMP-2 activity in chronic hepatitis is contrary to decrease at lowest among them. The level of MMP-9 similarly low compare with normal control. Therefore found out that the process from chronic hepatitis to hepatoma, a variation of MMP-2 is earlier to decrease and then to rise. Although there is no great variation but lower in MMP-9 compare to normal control.

肝癌病人的血清中MMP-9及MMP-2两者的变化与正常人相比差距最易观察，当比较所有非癌症病人血清时，慢性肝炎病人血清MMP-2活性表现相反的下降，而且是其中最低的，因此可以看出由慢性肝炎到肝癌的过程MMP-2的变化是先下降再升高，MMP-9虽然没有大变化，相较於正常人却都偏低。
