Abstract:
Objective To investigate the changes and significances of vaginal microecology in elderly postmenopausal women.Methods 50 postmenopausal women and 68 reproductive age women with no subjective symptoms and normal vaginal microecological who had health examination in Beijing Hospital were selected.The contents and strains of vaginal lactobacilli in both groups were detected by polymerase chain reaction (PCR),and their differences between the two groups were analyzed.Results 92％ (46 cases) of postmenopausal women had only one vaginal lactobacillus strain in vaginal,and 8％(4 cases) of them had two lactobacillus strains in vaginal.But 4％(3 cases) of reproductive-age women had only one vaginal lactobacillus strain in vaginal,and 96％ (65 cases) of them had two and more lactobacillus strains in vaginal.There was a significant difference in the strains of vaginal lactobacilli between the two groups (x2=91.035,P=0.000).The strains of vaginal lacmbacilli ranking top 4 detection rate was Lactobaeillus jensenii (30.0％),Lactobacillus gasseri (22.6％),Lactobacillus crispatus (16.9％) and Lactobacillus inert (13.2％) in postmenopausal women,while Lactobacillus inert (80.8 ％),Lactobacillus crispatus (70.5 ％),Lactobacillus gasseri (67.6％) and Lactobacillus jensenii (39.7％) in reproductive-age women.The content of 16s rDNA from vaginal lactobacillus was more in reproductive age women than in postmenopausal women [(87.3 ±0.8) ng/g total DNA vs.(35.1±3.6) ng / g total DNA,t=6.514,P=0.048].Conclusions Lactobacillus strains colonizing in vaginal are different between postmenopausal women and reproductive age women,and the content of the vaginal lactobacillus is reduced significantly in postmenopausal women.
