RESUMEN

Interleukin-22 (IL-22) is a member of the IL-10 family, which exhibits a similar structure and immune function with IL-10. IL-22 is mainly secreted by Th22, Th1, and Th17 cells, innate lymphoid cells (ILCs), and γδT and NKT cells. IL-22 is mainly in-volved in autoimmune diseases, malignant tumors, and infective diseases. As such, studies have focused on the function of IL-22 cyto-kine in the pathogenesis of various malignant tumors. Studies revealing the expression and pathogenesis of IL-22 in malignant tumors possibly provide a new method to treat and prevent malignant tumors. In our study, the discovery, structural characteristics, and func-tions of IL-22 in malignant tumors are reviewed.

RESUMEN

Objective To investigate the value of biliary tumor markers for differential diagnosis of the benign and malignant biliary tract diseases.Methods Tumor markers (CA19-9,CEA and CA242) examination and bacterial culture were performed in a total of 160 patients,who underwent therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for biliary diseases.Resuts There were significant differences between malignant group and benign group in bile and serum in the level of CA19-9,CEA and CA242 (P <0.05) ; Cut-off value,according to ROC curve,was 239 ku/l in CA19-9,40 ng/ml in CEA and 60 ku/ml in CA242,respectively.There were significant differences between the bile marker and the serum marker in sensitivity,accuracy,negative predicative value of CEA (P < 0.05).No significant differences was found in specificity between the serum group and the bile group.There were significant differences in bile CA19-9 level between cholangiocarcinoma,pancreatic cancer,duodenal papilla carcinoma with carcinoma metastasizing to bile duct,and hepatocellular carcinoma (P < 0.05).Both in benign group and malignant group,there were significant differences in CA19-9 level between infectious bile and noninfectious bile (P < 0.05).Conclusion The level of CA19-9,CEA and CA242 in bile can be applied to differentiate benign and malignant biliary diseases.The bile tumor markers do not have advantage over serum tumor markers in specificity for diagnosis.Bile bacterial infection can result in the elevation of bile CA19-9 while it does not have impact on differential diagnosis.

RESUMEN

Objective To evaluate the cooperation and nursing during esophageal variceal ligature with painless endoscopy.Methods The cooperation and nursing intervention of 290 patients with esophageal varices treated with painless endoscopic loop ligature from January to December 2009 were analyzed retrospectively.Results The treatment of 290 patients were succeessful.There was no anesthetic accident and serious complication.The treatment was successfully completed in the safe,calm and comfortable painless condition.Conclusions Esophageal variceal ligature with painless endoscopy is a safe and painless method which is easily accepted by patiens.The key point of the successful treatment is close cooperation and the deliberate nursing.
