H.p Introduction
Helicobacter pylori(abbr. H.p), be found by Austrilian scholar Marshall and
Warren in 1983, accordingly they won Nobel Prize for Medicine
Featu re
1. Patchy distribution
2. Secrete specific urease
3. Zero Self-Cure Rate(once infected,can’t
be self-cure without professional treatment)

Urease Role
Urease is a substance produced by Hp, it can decompose the urea into
carbon dioxide and ammonia. Ammonia can form cloud shape around Hp
bacteria, neutralize gastric acid, play a protective role on Hp

5.

Relationship between pH and Urease
Stronger acidic, bigger urease activity of Hp, bigger ability of
decompose urea
but other bacteria is opposite
low pH
high acidity
big urease activity of Hp

New data of epidemiological
50% gastric cancer growth and death in China
The trend will still increase from 2012 to 2030
Hp causes 64% gastric cancer
Eradication Hp infection can reduce 39% of gastric
cancer and precancerous lesion
Most of gastric cancer(>95%) caused by HP
