Objective: To explore the clinical significance. Methods: The double-antibody sandwich ELISA technique. Result: The serum interleukin-6(IL-6) levels of patients with cholangiocarcinoma are significantly higher than those in benign biliary disease and normal controls (P<0.05). Conclusion: Serum IL-6 levels of patients with cholangiocarcinoma are significantly increased ,it is one of the important parameters for clinical evaluation in patients of cholangiocarcinoma.

Objective To compare the efficacy of a self-applied modified Semont maneuver(MSM) with self-treatment using a modified Epley procedure(MEP) in patients with posterior canal benign paroxysmal positional vertigo(PC-BPPV).Methods All 70 patients with PC-BPPV were treated respctively by using MEP and MSM between July 2001 and June 2003,remission rate and treatment-related side effects were compared at the end of 1 week.Results Remission rate was 95% in the MEP group(n=37) vs 58% in the MSM group(n=33,P
