Résumé
Objective To detect the anti EZH2 autoantibodies IgG expression in hepatocellular carcinoma patient's serum samples and investigate the relationship of anti EZH2 autoantibodies IgG expression with clinicopathological parameters.Methods ELISA method was used to detect the anti EZH2 autoantibodies in serum of 120 cases of HCC patients and compared with 115 healthy controls.Results Serum anti EZH2 antibodies in patients with hepatocellular carcinoma group the content of IgG was 2.015±0.568 μg/ml group,anti EZH2 antibodies IgG content control health was 1.185±0.289 μg/ml.There was significant difference between two groups (t=12.48,P＜0.001).Anti EZH2 antibodies of IgG in serum of pa ticnts with hepatocellular carcinoma was up-regulated and the degree of tumor size,tumor the degree of differentiation,TNM grading and intrahepatic metastasis (t=8.485 ～ 57.93,P＜0.001).And age,sex,drinking,whether HBV infection had no significant difference (t=1.22～5.20,P＞0.05).Conclusion The expression of anti EZH2 autoantibodies in serum was related to the occurrence and development of hepatocellular carcinoma,and the detection of serum anti EZH2 autoantibodies in serum of liver cancer may be helpful to judge the malignant behavior and prognosis of hepatocellular carcinoma (HCC).which may be used as a refcrcnce for the evaluation of the prognosis of HCC patients with IgG antibody against IgG.
Résumé
Objective To investigate serum anti-insulin-like growth factor-Ⅱ mRNA binding protein1(IMP1) autoantibody IgG expression in hepatocellular carcinoma(HCC) patient and its relationship with clinicopathological parameters.Methods ELISA method was used to detect serum anti-IMP1 autoantibody IgG in 120 cases of HCC,then the detection results were compared those in 115 healthy individuals(control group).The relationship between serum anti-IMP1 autoantibody IgG level with clinicopathological parameters in HCC patients was analyzed.Results The serum anti-IMP1 autoantibody IgG levels in the HCC group and control group were(1.512±0.685),(1.080±0.301)μg/mL respectively,the HCC group was significantly higher than the control group with statistical difference(P0.05).Conclusion Serum anti-IMP1 autoantibody IgG expression increased is increased in HCC patient.The detection of serum anti-IgG autoantibody IMP1 level in HCC is conducive to judge the malignancy degree of HCC.
