Study On The Correlation Between TCM Classification Of Low Level Obstructive Jaundice And The Ultra-high Field MRCP Extrahepatic Image Changes

Objective:Traditional Chinese medicine plays an active role in the treatment of jaundice,and MRI and MRCP technique play an important role in obstructive jaundice.Moreover,with the increase of magnetic resonance scanner field intensity and the continuous maturity of MRCP technology,the accuracy of the diagnosis of obstructive jaundice has been increasing,and some recognized image changes have been formed.Therefore,this paper discusses the relationship between the TCM classification of low obstructive jaundice and the change of ultrahigh field intensity MRCP image,and seeks the visibility basis of TCM clinical dialectical classification.Methods:MRCP was analyzed in 70 patients with low-level obstructive jaundice.According to TCM theory and dialectical classification by senior Chinese medicine practitioners,it was divided into Yang Huang and Yin Huang.Yang Huang main Yellow bright,with heat,mouth bitter,yellow greasy fur,wiry pulse.Yin yellow main Yellow faint,with less satisfied,weak,pale tongue,deep pulse.The width of the common bile duct dilatation was measured on the 3D-MRCP image,and the signs of obstruction were typed.The difference is compared between Yang Huang and Yin Huang in the bile dilation and imaging sings by using chi-square analysis and Fisher exact correction method.The difference was statistically significant with P<0.05.Results:1.In the jaundice of low obstructive jaundice,the propor tion of bile duct stones and cholangitis in Yang Huang was 48/50(96%),and the proportion of tumors in Yang Huang was2/50(4%).The proportion of tumors in Yin and yellow was 18/20(90%),and the proportion of bile duct stones and cholang itis in Yin Huang was 2/20(10%).2.According to the degree of biliary dilation,there was no statistically significant difference between light,moderate and severe(P = 0.379 0).There were statistically significant diff erences between mild and severe and moderate to severe(P=0.0000).3."inverted cup levy" and "rat-tail sign" and "Double duct sign","four-segment sign" and "cut off sign" image cha nges in the comparison of Yang Huang and Yin Huang,x2=28.2072,P<0.0001.Conclusion:1.The TCM classification of obstructive jaundice in ultra-high field MRCP,Bile duct stones and cholangitis are mainly Yang huang,the tumor is mainly Yin huang.2.In hyper-field MRCP,the degree of yellow extrahepatic bile duct dilatation is more obvious than that of Yanghuang,Yang-yang is more common in mild and moderate,and yin-yang is more common in severe.3."inverted cup levy" and "rat-tail sign" are closely related to patients with Yang Huang,and "Double duct sign","four-segment sign" and "cut off sign" are closely related to patients with Yin Huang.
