[Abstract]:Objective: to detect the expression of MAGE-A3, MAGE-A9 protein and gene in pathological diagnosis of cervical lesions, and to compare with normal tissues and study the relationship between MAGE-A3, MAGE-A9 and cervical intraepithelial neoplasia and the occurrence and development of cervical cancer, so as to provide a theoretical basis for the diagnosis and treatment of cervical lesions. Methods: a practical treatment scheme was taken. Methods: selected patients with cervical lesions admitted in our hospital in -2015 2009, 40 cases of cervical intraepithelial neoplasia (CIN III), 60 cases of Ia~b stage (FIGO staging) of cervical cancer, 24 cases of IIa stage (FIGO stage) of cervical cancer and 40 cases of normal cervix. All patients were treated with surgical treatment, consult the patient's medical records, combined with patient's presence. The pathological data of the bed were analyzed. All the pathological tissue wax blocks were collected, the immunohistochemical staining was performed and the expression of MAGE-A3 and MAGE-A9 was observed under light microscope. At the same time, the fresh surgical tissues were cut down in the operation room of our hospital in 2015 -2016, and the real time fluorescence PCR method was used to detect 15 cases of normal cervix, 15 cases of CIN III, and 20 cases of cervical cancer tissues, MAGE- The expression of A3, MAGE-A9 gene. The expression of MAGE-A3 and MAGE-A9 in 15 cases of normal cervix, 15 cases of CIN III tissue and 20 cases of cervical cancer were detected by Western Blot. Results: 1. immunohistochemistry showed that MAGE-A3 protein was mainly located in the cytoplasm, and the level of expression gradually increased with the severity of cervical lesions. The positive expression rate of A3 in normal cervix, CIN III and cervical cancer tissues was 5%, 15%, 48.81%, and the positive expression of three was gradually rising. The statistical analysis showed that the expression of MAGE-A3 in the cervical cancer group was significantly higher than that of the CIN group and the normal control group (P0.01), but the normal group and the CIN III group were significantly different. The difference was not statistically significant (P0.05). At the same time, the study showed that the expression level of MAGE-A3 and the clinical stage of cervical cancer, pathological classification, lymph node metastasis and high risk HPV infection were statistically significant (P0.05).MAGE-A9 protein was mainly located in the cytoplasm, MAGE-A9 was in the normal cervix, CIN III and cervical cancer tissues. The positive expression rates were 7.50%, 17.50%, 55.95% and three, respectively. The statistical analysis showed that the expression of MAGE-A9 was significantly higher in the cervical cancer group than in the CIN III group and the normal control group (P0.01), but there was no significant difference between the normal group and the CIN group (P0.05). The results showed that the expression level of MAGE-A9 and the clinical stage of cervical cancer, the pathological grades and the lymph node metastasis were statistically significant (P0.05).2. real-time fluorescence quantitative PCR method showed: (1) the relative expression level of MAGE-A3 mRNA in normal cervix, CIN III and cervical cancer tissues was 0.184 +, respectively, with GAPDH mRNA as the internal reference standard. The relative expression of 0.069,0.221 + 0.086 and 0.702 + 0.145.MAGE-A3mRNA in cervical cancer was significantly higher than that of CIN III and normal tissue. The difference between the cervical cancer group and the normal group and the group CIN III was statistically significant (P0.05), while the difference between the normal group and the CIN III group was not statistically significant (P0.05) (2) with GAPDH mRNA as the internal reference standard, normal cervix, CIN, and CIN. The relative expression level of MAGE-A9 mRNA in cervical cancer tissues was 0.182 + 0.062,0.234 + 0.087 and 0.642 + 0.150 respectively. The expression of MAGE-A9 in cervical cancer tissues was significantly higher than that of CIN and normal tissues. The difference between the cervical cancer group and the normal group and the CIN III group was statistically significant (P0.05), but there was no difference between the normal group and the CIN group group III group. The study significance (P0.05) 3.Western bloting Western blot showed: (1) the gray level of MAGE-A3 gradually deepened with the severity of cervical tissue lesion, and the relative expression level of MAGE-A3 protein in normal cervix, CIN III and cervical cancer tissues was relative expression of MAGE-A9 protein in 0.943 + 0.178,1.035 + 0.139,1.977 + 0.105. cervical cancer tissues The difference was significantly higher than that of CIN III and normal cervical tissue (P0.05), but there was no significant difference between the normal group and the CIN group (P0.05). (2) the gray level of MAGE-A9 gradually deepened with the severity of cervical tissue lesion, and the relative expression level of MAGE-A9 protein in normal cervix, CIN and cervical cancer tissues was 0.857 + 0, respectively. The relative expression of MAGE-A9 protein in.315,0.909 + 0.526,1.882 + 0.179. cervical cancer tissues was significantly higher than that of CIN III and normal cervical tissue (P0.05), but there was no significant difference between the normal group and the CIN group (P0.05). Conclusion: 1, the overexpression of MAGE-A3 is closely related to the development of cervical cancer, and the MAGE- is closely related to the development of cervical cancer, and MAGE- is closely related to the occurrence and development of cervical cancer, and MAGE-, and MAGE- The overexpression of A3 is closely related to the clinical stage of cervical cancer, pathological grading, lymphatic metastasis and high risk HPV infection, but not associated with age and cancer type. MAGE-A3 may be an early diagnosis of cervical disease. The important tumor marker for cervical cancer treatment can be an ideal target for the biological treatment of cervical cancer. To further understand the prognosis of cervical cancer biological behavior is of great clinical value.2, the overexpression of MAGE-A9 is closely related to the development of cervical cancer, and the overexpression of MAGE-A9 is related to the clinical stage of cervical cancer, pathological classification and lymphatic metastasis. MAGE-A9 may be the early diagnosis of cervical disease and cervical cancer. The important tumor marker,.MAGE-A9, may be an ideal target for the biological treatment of cervical cancer. MAGE-A9 is of great clinical value for the further understanding of the prognosis of cervical cancer biological behavior.
