### Question: Relationship between Helicobacter pylori negative chronic superficial gastritis and functional dyspepsia: are they the same disease?

### Context: 1: To discriminate between Helicobacter pylori (Hp) negative chronic superficial gastritis and functional dyspepsia (FD) from therapeutic point of view.
2: 214 patients with Hp negative chronic superficial gastritis were randomly assigned into two groups. One group was case control trial group, another was cross-treated self-control group. Ordinary treatment of chronic gastritis (plan A) and FD plan (plan B) were given. Symptoms and pathologic changes were analysed and compared.
3: In the case control group, the total effective rate of plan A and plan B was 89.2% and 88.5% respectively; in the cross-treated self-control group, the total effective rate of plan A and plan B was 81.8% and 89.8% respectively; There was no significant difference in the effective rate of the two different plans (P>0.05).


###Response: Hp negative chronic superficial gastritis is similar to FD from therapeutic point of view. The method of treatment of the two diseases may be same, though they are named differently.
