Abstract:
Objective To evaluate the relationship between functional oipA gene of Helicobacterpylori and digestive disease. Methods Biopsy gastric mucosa were obtained from 360 patients who would get gastroscopy.Hp were isolated from urease positive samples and partly urease negative samples,and improved by microscope,urease experiment and 16SrRNA PCR. OipA and cagA of the isolates were obtained by PCR and the statas of oipA signal region were analysised after sequencing. Analyze the relevance between functional oipA gene of Helicobacter pylori and digestive disease.Results 106 isolated Hp were obtained,in which 72 strains with cagA gene positive,87 with oipA signal region gene positive (80 the statas of signal region was on and 1 was off;6 could not be decided).The frequency of functional oipA were both significantly higher than cagA in ulcer and atrophic gastritis.Conclusion The relationship between functional oipA gene and digestive disease was more closer than that of cagA.
