Objective:
To establish the diagnosis evidence of objective tongue inspection for liver cancer (LC) patients with damp-heat syndrome (DHS) by dynamically observing their tongue figures using modern tongue image analytic apparatus, and to explore the effect of intervention on the tongue figures.
Methods:
Tongue figures were collected from 142 LC patients with DHS by tongue image analytic apparatus. Red (R), green (G) and blue (B) values were analyzed. The r and g values were calculated requesting r=R/(R+G+B), g=G/(R+G+B), and b=1-r-g, and scored in combination with Chinese medical symptoms scale. The tongue figure and correlated scores were collected from 59 of them 3 days after transcatheter arterial chemoembolization intervention.
Results:
The range of objective tongue inspection of LC patients with DHS was as follows: as for tongue fur, 0.360
Conclusion:
The range of objective tongue inspection of LC patients with DHS could be known by collecting and analyzing objective indicator of tongue figures, thus laying foundation for further studies with analysis of correlation between intervention and Chinese medicine based on tongue figures.
