ABSTRACT

Objective To investigate the clinical value of combined detection of glycoprotein 125 (CA125) and human epididymis protein 4 (HE4).Methods 46 patients with ovarian malignant tumor (malignant tumor group) and 48 patients with benign ovarian tumors (benign tumor group) treated in our hospital from June 2013 to August 2015 were selected.The serum levels of CA125 and HE4 were detected in all the patients and its diagnostic value was evaluated by ROC curve.The levels of CA125 and HE4 in patients with different pathological types were compared.Results The best diagnostic value of CA125 was 47.9 U/L,The serum level of CA125 ≥47.9 U/L predicted the specificity of ovarian malignant tumor was 87.34% and that the sensitivity was 76.69%.The best diagnostic value of HE4 was 55.68 pmol/L.The serum level of HE4 ≥ 55.68 pmol/L predicted the specificity of ovarian malignant tumor was 90.34% and that the sensitivity was 83.01%.There was significant difference in CA125 and HE4 between the patients with benign and malignant ovarian tumors (P0.05)However,the sensitivity was significantly higher than that of single detection,the difference was statistically significant (P<0.05).The levels of CA125 and HE4 in patients with epithelial ovarian tumors were higher than those with non epithelial ovarian tumors,and the difference was statistically significant (P<0.05).The levels of CA125 and HE4 in patients with mucinous ovarian cancer were significantly lower than those in patients with serous ovarian cancer (P<0.05).Conclusion The combined detection of serum CA125 and HE4 can significantly improve the value of differential diagnosis of ovarian tumors,and CA125 and HE4 may play an important role in the pathological classification of malignant ovarian tumors.

ABSTRACT

AIM: To investigate the mechanisms of augmenter of liver regeneration (ALR) in promoting damaged hepatocyte proliferation.METHODS: The effects of Kupffer cell condition medium (KCCM+) stimulated by ALR on damaged hepatocyte proliferation were studied by MTT. The localization of ALR binding to Kupffer cell membrane and in intact rat liver was studied by immunohistochemistry. The IL-6 expression in Kupffer cells stimulated with ALR was observed by immunohistochemistry. RESULTS: The proliferation of damaged hepatocytes stimulated with KCCM+ was increased significantly. ALR immunostaining particles in plasm of hepatocyte were found in intact liver. The rough immunostaining particles of ALR were seen on the surface of Kupffer cell membrane. Immunostaining particles of IL-6 in Kupffer cells induced by ALR increased. CONCLUSION: ALR promotes proliferation of damaged hepatocytes indirectly by stimulating Kupffer cells.
