In the comparison of doppler flow charts in the chronic gastritis group, there were statistically significant differences in VD, VM, D, RI, SV, ET between cun-kou artery and anterior tibial artery(P <0.05), and there were more statistically significant differences in PI between cun-kou artery and anterior tibial artery(P < 0.01). In the comparison of doppler flow charts between normal group and chronic gastritis group, there were statistically significant differences in SV, ET between normal group and chronic gastritis group(P < 0.05), and there were more statistically significant differences in PI between normal group and chronic gastritis group(P < 0.01).CONCLUSION: Based on the differences in doppler flow charts between the normal group and the chronic gastritis group, the doppler flow charts of cun-kou artery and anterior tibial artery were not only proved to be significantly different, but also provided quantitative objective indexes for the study of cun-kou artery and anterior tibial artery doppler flow charts of normal people and chronic gastritis patients. This study also proves that the doppler flow chart of the anterior tibial pulse is of great significance for the diagnosis of chronic gastritis.展开更多
