Abstract:
Objective To study the relationship between Helicobacter pylori (Hp) DNA positive detection in bile of gallbladder and intragastric Hp's colony and its plausible mechanism.Methods Sixty patients of gallbladder innocence diseases were recruited in the case group and 30 health populations were recruited in the control group.13CPDB was used to detect the infection of Hp.The cytotoxin associated gene antigen (cagA) in gall and gall-stone were detected through PCR.The empty function was tested through B ultrasound.Results The infection rate of Hp in all cases is 50.0% (30/60) and 7 of 30 bile (23.3%) ,1 of 30 gallstones (3.3%) were positive for Hp cag-A by PCR analysis in positive Hp infection group,with none of the 30 bile were positive in negative group( x2 = 5.822 ,P ＜ 0.05 ).The contraction rate of gallbladder of Hp positive group ( 56.8 ± 17.1 ) %was lower than negetive group' s ( 69.4 ± 13.1 ) % and the control group' s (63.3 ± 17.1 ) % ( F = 5.633,P ＜0.05).Conclusions Hp DNA is present in bile of gallbladder,and is related with Hp infection in stomach.Impairment of the gallbladder empty function may be related with Hp infection.
