But it was at the subcellular molecular biological level that we explored the pathophysiologic basis of classification of spleen deficiency in chronic gastritis by detecting the bioactive substances in gastric mucosa nuclei and mitochondria. Methods By means of optical microscope, scanning electron microscope (SEM), transmission electron microscopy (TEM) and histochemical staining, we conducted histopathological, subcellular ultrastructural analysis and nuclei and mitochondrial ultrastructural analysis of gastric mucosa of 188 spleen deficiency patients and of 42 voluntary blood donors. At the same time, bioactive substances were measured by means of X-ray energy dispersive analysis system (EDAX) image analysis system, radioimmunoassay method and chemiluminescence method. Results The content of cAMP, superoxide dismutase (SOD), Zn and Cu in gastric mucosa, and the content of Zn and Cu in mitochondria decreased progressively in order of groups: healthy control (HC), spleen Qi deficiency without organic lesion (F-SQD), spleen Yang deficiency without organic lesion (F-SyangD), disease without symptoms group, spleen Qi deficiency with organic lesion (G-SQD), spleen Yang deficiency with organic lesion (G-SyangD), spleen Yin deficiency (SyinD) and spleen deficiency with Qi stagnation (SDQS), chronic spleen deficiency gastritis (CSG) and chronic atrophic gastritis (CAG); decreased in order of HC, intestinal metaplasia (IM)Ⅰ_a, IMⅠ_b, IMⅡ_a and IMⅡ_b, P<0.05. The content of DNA, Zn and Cu in nuclei progressively increased in order mentioned above, P<0.05.Conclusions The quantitative changes of gastric mucosal cAMP, SOD, Zn, Cu, of mitochondrial Zn, Cu and of nuclear DNA, Zn and Cu are not only the substance base on which the lesion of gastric mucosa tissue structure occurs, but also the substance base on which spleen deficiency is classified. G-SQD and G-SyangD were more likely to be found in low-grade or middle-grade CSG and CAG, while SyinD and SDQS in middle-grade or high-grade CSG, CAG and IMⅡ_b.展开更多
