Exploring the digital and quantitative four diagnostic features in traditional Chinese medicine(TCM)of Glomerulonephritis，and provides some revelation for promoting the development of glomerulonephritis and treatment technology.Methods:According to the above standards，select 30 glomerulonephritis patients randomly as the experimental group，while 30 healthy people as the control group.By applying the four diagnosis auxiliary apparatus to collect four clinical diagnosis information and summarizing the statistical analysis of four diagnosis information at the same time.Results:Comparing with the control group，the value of the experiment group pulse wave conduction velocity and string and tightness were higher，the ratio of the experiment group red，crimson of tongue yellow and thick of tongue were higher，the water type constitution ratio is higher，and there was statistically significant differences between the two groups(P<0.05).Conclusion:The results of differences in pulse diagram parameters were consistent with the theory of classical TCM pulse theory.The results of differences in pulse wave velocity conform to the modern medical research.By applying four diagnostic and auxiliary apparatus and acquiring patients’ important digital and quantitative information，it is more advantageous to combine traditional Chinese and western medicine on the diagnosis and treatment to control the vicious incident vascular complications and blood vessels.
