The virtuous effect of heat shock protein 70 and evil effect of nuclear factor-kappa B in patients with chronic gastric disease of PI-Wie damp-heat syndrome type

It has been proved in recent studies that the chronic gastric disease (CGD) of Pi-Wei damp-heat syndrome type (CGD-PWDH) is closely related with heat shock protein 70 (HSP70) and nuclear factor-kappa B (NF-kappaB). HSP70 can protect the auto-stability of cells and elevate the immune function in organism against tumor or multiple exogenous pathogens. Increasing of NF-kappaB expression presents in case of Helicobacter pylori (Hp) stimulation, it could induce inflammatory reaction, while inflammation factors could act inversely to enhance the expression of NF-kappaB, thus to cause and expand the damage of gastric mucosa. In addition, HSP shows blocking effect on the activation and expression of NF-kappaB. So, the author considered that in patients of Hp associated CGD-PEDH, HSP 70 exhibits the effect as that of "vital energy" and NF-kappaB play a role as the "evil qi" in Chinese medicine, the expressions of the two may embody the vital-evil combating manner of Pi-Wei damp-heat syndrome.
