Abstract:
Objective To investigate the effects of changes in protein bile sugar chain structure for differen-tiating benign and malignant biliary tract disease .Methods 100 patients with biliary tract diseases who were treated in Department of General Surgery ,Qingdao Haici Medical Group were selected in this study .According to benign or malignant biliary disease ,the patients were divided into control group ( benign biliary tract disease ) and observation group ( cholangiocarcinoma ) ,50 cases in each group .Two groups of patients with bile drops on the nitrocellulose mem-brane,through the comparison of wheat germ agglutinin (WGA),Datura stramonium agglutinin (DSA),lentil lectin (LCA),concanavalin A(CONA) positive rate of test,to explore the relationship between sugar chain of glycoprotein in bile and bile duct benign and malignant diseases .Results In control group,the positive rates of WGA,DSA,LCA, CONA agglutinin test were 22.0%,14.0%,2.0%,76.0%,those in the observation group were 76.0%,66.0%, 76.0%,82.0% respectively.No statistically significant difference between the two groups of CONA agglutinin test positive rate was observed(P>0.05).The WGA,LCA,DSA agglutination test positive rates in observation group were significantly higher than those in the control group ,the differences were statistically significant (χ2 =29.17,28.17, 57.55,all P<0.05).Conclusion Changes in bile glycoprotein chain structure are closely related to benign and ma -lignant biliary tract disease ,positive rates of WGA ,LCA,DSA agglutination test can be used to determine the benign and malignant biliary disease ,it should be popularized in clinical practice .
