Binding inhibition test by SABC-ELISA method were performed for the measurement of the antigen level. Results showed that the associated antigen detected in feces of patients with colon cancer were significantly higher than that of non-cancer disease or normal subjects. The positive rates were 61.1% as detected with CL-2; 53.4% with CL-3; 55.0%, PS-9; and 53.3% PS-10 in cancer patients while that in normal subjects were 7%; 9%; 8%; and 8% respectively. When 'cocktail' of CL-2, PS-9 and PS-10 were used, the positive rates were 92.5% in colon cancer and 14% in normal subjects. In seven out of the sixty patients with colon cancer studied who were graded as Dukes A, the results were all positive. The results seem superior to the serologic detection and may provide a promising new approach in the early diagnosis of colon cancer.展开更多

Methods 3AO cell proliferation was evaluated by viable cell count, percentage of cells in each cycle phase were analyzed by flow cytometric analysis, alkaline phosphatase (AKP) activity was determined as described , and CA125 expression was measured by ELISA. Results RA could inhibit the proliferation of 3AO cells accompanied with morphological changes in a dose-dependent manner. Cell cycle analysis indicated that RA inhibition of 3AO cells growth occurred through induction of G1 arrest with a concomitant reduction in the proportion of cells in S phase, AKP activity increased significantly after treatment with RA(0.1 μmol/L) for 1-5 days. Dose-response studies revealed that the AKP activity increased to a different extent as a function of RA concentrations. Furthermore, RA could suppress the expression of CA125 tumor marker in 3AO cells.Conclusion RA could markedly inhibit the proliferation and induce the differentiation of 3AO cells. for 1-5 days.

Methods Ten cases of normal ovarian tissues and 75 cases of ovarian epithelial neoplasm tissues were detected by immunohistochemical methods: S P for bFGF, FGFR 1,double immunohistochemistry Lab SA for Ki 67 antigen and bFGF. Results The expression level of bFGF, FGFR 1in ovarian epithelium and ovarian epithelial neoplasm showed a step wise increase in the following order:normal <benign <borderline <malignant; The expression level and intensity of bFGF and FGFR 1 were increased with the decrease of differentiation degree and increase of clinical stage in ovarian carcinoma; There was no statistical difference between the expression of bFGF, FGFR 1 in serous cystadenocarcinoma and that of mucinous cystadenocarcinoma; The expression of bFGF was correlated with that of FGFR 1 in neoplastic tissues; There were positive expression rates of bFGF and Ki 67 antigen in ovarian epithelial neoplasm. Conclusion As an important proliferative factor, bFGF plays an important role in carcinogenisis and progression of ovarian epithelial neoplasm.展开更多

In addition, 120 cases of benign ovarian tumors in the same period were selected as the benign group, and 92 healthy women who came to the hospital for health examination were selected as the control group. Serum HE4, CA125 levels and positive rates were detected by microparticle enzyme immunochemiluminescence assay, and ROMA index values were combined to assess the risk of ovarian cancer.Results:Malignant group serum CA125, HE4 level and ROMA index were significantly higher than those in the benign group and the control group, the level of CA125 in positive group was higher than control group, but the difference in level of HE4 and ROMA index between benign group and control group was not statistically significant. The positive rates of serum CA125, HE4 and ROMA index in malignant group were 76.4%, 92.7%, 96.4%, which were significantly higher than those in benign group (28.3%, 18.3%, 15%). The negative predictive value, positive predictive value, specificity and sensitivity of CA125 were all lower than those of HE4. The negative predictive value, positive predictive value, specificity and sensitivity of the combined ROMA index were higher than those of single diagnosis.Conclusions: Serum CA125, HE4 and ROMA index in elderly patients with ovarian cancer are significantly higher than those in elderly patients with benign ovarian tumors and healthy women. The combined diagnosis is the highest, with Gao Min's high sensitivity and specificity, which can be popularized in clinical practice.展开更多

Expression of CD80 mRNA was examined by reverse transcriptions-polymerase chain reaction(RT-PCR).Results:The positive rate of HLA classⅠ was 59.09%.CD80 mRNA was expressed on 9.09% of all 44 EOC tissues.HLA classⅠ expression rate in stage Ⅲ-Ⅳ was lower than that in stage Ⅰ-Ⅱ;in tumors of node-positive patients was lower than that of node-negative patients(P<0.05).In patiens with tumors expressing HLA class Ⅰ antigens,recurrence rate was lower than that in patients with tumors deficient in HLA class Ⅰ(P<0.01).In four patients with tumors expressing CD80 mRNA,recurrence did not occur,in contrast to patients with tumors lacking CD80 mRNA,in whom tumor relapse rate was 57.5%(P<0.05).Relapse ratein tumors deficient both HLA class Ⅰ and CD80 was significantly higher than that of tumors coexpression the two molecules.Conclusions:EOC cells may escapefrom the immune surveillance of the host through downregulating expressions ofHLA class Ⅰ and CD80.Evaluation of expressions of these surface immunoregulatory molecules may be helpful for judging prognoses of EOC patients and guiding immunotherapy.展开更多
