| helicobacter pylori-associated gastritis and gastric carcinoma in beijing. | a retrospective study was performed on 500 consecutive gastric biopsies obtained from patients with a diagnosis of gastritis and gastric carcinoma. overall, helicobacter pylori was detected in 336 cases (67.2%); it was seen in 82.4% of patients with duodenal ulcer, 80.1% of patients with gastric ulcer, 76.1% of patients with chronic atrophic gastritis, 60.3% of patients with chronic superficial gastritis, and 32.1% of patients with gastric carcinoma. the gastric epithelium colonized by helicobac ... | 1993 | 8189377 |

| [epidemiology of helicobacter pylori infection in shandong and beijing areas.]. | to study the current prevalence and recent epidemiological changes of helicobacter pylori (h. pylori) infection among children and adults residing in regions with high (muping, shandong) and low (yanqing, beijing) incidence of gastric cancer in china. | 2009 | 20193516 |
| recent changes in the prevalence of helicobacter pylori infection among children and adults in high- or low-incidence regions of gastric cancer in china. | the prevalence of helicobacter pylori (h. pylori) infection varies by geographic locations. studies indicate that the infection rate of h. pylori was previously high in china but that rates had been declining worldwide over recent decades. the aims of our study were: (1) to determine the current prevalence of h. pylori infection among children and adults residing in areas with high (muping county, shandong) and low (yanqing county, beijing) incidences of gastric cancer in china, and (2) to compa ... | 2009 | 19781321 |
| core genome haplotype diversity and vaca allelic heterogeneity of chinese helicobacter pylori strains. | the human gastric pathogen, helicobacter pylori, has co-evolved with its host and established itself in the human stomach possibly millions of years ago. therefore, the diversity of this bacterium is important in its clinical manifestations. our aim has been to evaluate the genetic diversity of 40 h. pylori clinical isolates from four different parts of china. the methods of multi-locus sequence typing and vaca allele genotyping were used to assess their genetic diversity. to discriminate mlst, ... | 2009 | 19452214 |

| primary antibiotic resistance of helicobacter pylori isolated from beijing children. | the antimicrobials resistance of helicobacter pylori (h. pylori) was able to sharply decline the eradication rate of h. pylori both in adults and children, but there are limited studies about the primary antibiotic resistance and the related gene mutations, specifically in china. | 2011 | 21923681 |
