Study the relationship between TCM spleen def iciency syndromes and gastric precancerous lesion / 中华中医药杂志

ABSTRACT

Objective:To explore the relationship between the pathophysiological changes in TCM spleen de ciency syndromes and precancerous lesion of gastric mucosa.Method:160 cases with spleen de ciency syndromes accompanied by gastric mucosa intestinal metaplasia,IM and / or atypical hyperplasia,AHP,(spleen de ciency is divided into spleen qi de ciency or SQD,spleen yin de ciency or SyinD and spleen de ciency with qi stagnation or SDQS) and 22 cases in health control group were taken as the study object.The detection was conducted on such trace elements as Zn,Cu of gastric mucosa epithelial cell nuclei and mitochondrion under the direct view of CM200FEG –TEM by adopting 9100/60 -Energy Dispersion X-ray Analyzers;detection was conducted on epithelial cell nucleus DNA by using IBAS2000 image analyzer;detection was conducted on the expression of P53,Ki67,CerbB2,P21ras in gastric mucosa tissue slices by adopting ElivisionTM Plus'.Result:The quantitative changes of gastric mucosa epithelial cell nucleus DNA,Zn,Cu and the positive expression rates of P53,P21ras,CerbB2 and Ki67 increased in the sequence of SQD group,SyinD group and SDQS group,while mitochondrial Cu,Zn decreased in the same sequence,there was signi cant di erence between the groups(P
