幽门螺杆菌感染与胆囊结石形成的相关性分析

目的:研究和探讨幽门螺杆菌(Helicobacter pylori,Hp)与胆囊结石形成关系,寻找Hp在胆道中存在的证据,同时对胆道中HpDNA的检测方法进行研究和分析.方法:参照文献对120例胆囊结石患者胆汁、粘膜和胆石进行Hp培养,并以Ure A和cagA作引物进行扩增,对扩增产物进行分析.结果:120例样本检测均为阴性结果,培养无Hp生长,使用PCR方法未检测到Hp DNA及Hp CagA抗体.结论:(1)运用PCR方法在胆汁和胆石中检测HpDNA尚受到多种因素制约.(2)Hp可能经Oddi's括约肌逆行的进入胆道但与胆囊结石并无明确相关性.

Analyze the associativity between Helicobacter pylori infection and cholecystolithiasis

Objective:To investigate the relationship of H pylori with cholecystolithiasis,to collect the evidence of Hp existing in biliary tract,and to study the detective method of Hp DNA in billiary tract.Methods:Hp which existing in bile,mucosa and gallstone of 120 cholecystolithiasis patients were cultured according to the literature.Then they were amplified by the primer of Ure A and cagA.Amplified products were analyzed.Results:All of the 120 samples were negative.No Hp grew in the medium.No Hp DNA and Hp Cag A antibody were found with PCR method.Conclusion:(1) It was restricted by many factors that Hp DNA in bile and gallstone wereexamined with PCR.(2) Hp maybe entered biliary tract regressively through Oddi's sphincter andhad no relationship with cholecystolithiasis.
