Abstract: Abstract: Objective: To investigate the expression of Slug gene in cervical carcinoma and normal cervical tissues and its value in the diagnosis and treatment of cervical cancer. Methods: in 40 cases of cervical cancer patients from March 2013 to March 2015 were as study object, which is selected as the experimental group, and 40 cases of normal cervical tissue as the control group, using quantitative PCR method to detect two groups of subjects, comparative analysis of relative expression of Slug gene in cervical carcinoma and normal cervical tissues, the correlation analysis on the clinical pathological parameters of this gene and cervical carcinoma. Results: the relative expression of Slug gene in the experimental group was (4.69 + 1.13) I * 10, the relative expression of Slug gene in control group was (1.32 + 0.31) x 10 I, the relative expression of Slug gene in the experimental group were significantly higher than the control group, the two groups have great difference, P<0.05. The relative expression of Slug gene in tissues of experimental group patients with cervical node metastasis and International Obstetrics and Gynecology alliance with the lymph, and the relationship between the larger, P<0.05; and Never mind, age, tumor size and differentiation degree of P>0.05.. Conclusion: Slug gene in cervical cancer relative expression has significantly increased, and has good value in the diagnosis of cervical cancer that is a good method for detection and diagnosis, is worthy of popularization and application.
