Objective To study the expressions of CA19-9 and CA125 and their clinicopathologic significances in gallbladder adenocarcinoma, pericancerous tissues and chronic cholecystitis. Methods EnVisionTM immunohistochemistry was used for assaying the expressive levels of CA19-9 and CA125 in the routinely paraffin-embedded sections of specimens from gallbladder adenocarcinoma (n=108), pericancerous tissues (n=46), and chronic cholecystitis (n=35). Results The positive rates of CA19-9 and CA125 were significantly higher in gallbladder adenocarcinoma (49.1%, 51.9%) than those in pericancerous tissues (26.1%, 15.2%) and chronic cholecystitis (14.3%, 5.7%), respectively (P

Objective　To investigate the clinical significance and relationship among Pre-S2、6 common types of HBV serum immune markers(HBV-M)and HBV-DNA.Methods　Using PCR to detect HBV DNA and ELISA technique to detect Pre-S2,6 kinds of HBV-M in the meantime.Results　Positive infection rates of HBV DNA in 6 common types of the 1484 cases were 89.8%>55.6%>21.8%>7.5%>7.1%>6.8% respectively,namely the model (1)>(3)>(2)>(5)>(6)>(4);but the positive cases of HBV serum immune markers were in the order (2)>(1)>(3)>(4)>(5)>(6).The positive rates were significant difference between Pre-S2 and HBV DNA in (2)、(3) types (P<0.01) and no significant difference in other types(P>0.05).Conclusion　It is necessary to detect Pre-S2,HBV DNA and HBVserum immune markers,but HBV serum immune makers and Pre-S2 detected by ELISA only external indication and indirect evidence of HBV infection.While the detection of HBV DNA by PCR was direct evidence of HBV infection.Therefore they have their unique clinicl significance.

Objective To study the expressive levels of galectin-3 (gal-3) and sambucus nigra agglutinin(SNA) and to detect their clinicopathological significances in benign and malignant lesions of the gallbladder. Methods EnVisonTM Immunohistochemistry for assaying gal-3 expressive levels and ABC cytochemistry for determining SNA expressive levels were used in conventional paraffin-embedded sections from the specimens of adenocarcinoma (n = 108) , peritumoral tissues (n=46) . Adenomatous polyp (n=15), and chronic cholecystitis (n = 35). Results The positive rates of gal-3 and SNA were significantly higher in adenocarcinoma (62. 0%, 66. 7%) than in peritumoral tissues (39. 1%,45.6%), adenomatous polyp (26.7%, 33.3%) and chronic cholecystitis (11.4%, 11.4%)(P<0. 05 or P<0. 01). The positive gal-3 and SNA in benign cases showed atypical hyperplasia of the epthelium. The positive rates of gal-3 and SNA expression were significantly lower in well-differentiated adenocarcioma, mass with a maximal diameter of <2 cm, absence of lymph node metastasis,and absence of invasion to adjacent tissues than in poor-differentiated adenocarcinoma, mass with a maximal diameter of ≥2 cm, lymph node metastasis and invasion to adjacent tissues. (P<0. 05 or P<0. 01). There was a significant correlation between the expressive levels of gal-3 and SNA in gallbladder adenocarcinoma (x2=9. 51, P<0. 01). Conclusions The expressive levels of gal-3 and SNA lectins had important effects on carcinogenesis, progression and biologic behaviors of gallbladder cancer. Patients with positive gal-3 and /or SNA expressions had poor prognosis.
