Aim: To investigate clarithromycin resistance positions 2142, 2143 and 2144 of the 23SrRNA gene in Helicobacter pylori (H. pylori) by nested-allele specific primer-polymerase chain reaction (nested-ASP-PCR).
Methods: The gastric tissue and saliva samples from 99 patients with positive results of the rapid urease test (RUT) were collected.
Objective: To study the physiopathologic basis of Weikangfu Granule (WKFG) in treating precancerosis of gastric mucosa in patients of chronic gastritis with Pi-deficiency syndrome (CG-PDS).
Methods: One hundred and fifteen patients of CG-PDS who suffered from intestinal metaplasia (IM) and atypical hyperplasia (ATHP) of gastric mucosa, were divided into two groups. The treated group (n = 61) was treated by WKFG with its ingredients modified according to the syndrome type of patients.
